Abstract

<P>PROBLEM TO BE SOLVED: To provide a sun tracking type solar energy receiving body device of good cost performance enhanced in quality and performance with a high practical value. <P>SOLUTION: The solar energy receiving body device is formed as a three-point support device by obliquely installing a solar panel rotation body, installing two separate lower parts with wheels or the like while setting an upper part as the rotational center, and moving one side in an azimuth displaceable manner by a sun tracking command part (an electronic circuit or a CPU) with respect to an installation surface by a sun tracking drive unit. Stable horizontal turning can thereby be attained regardless of during movement or stop. Further, since the upper part is rotatably supported by a shaft tower, its outside is open to facilitate assembly and maintenance and inspection. Since the lower parts located at the opposite extremes of the panel rotational center are driven, driving with small power can be attained. A hot water storage tank is fixedly provided while maintaining this basic structure. An elevation angle displaceable state is obtained, and an automatic handle is attached. A panel lock mechanism for stopping the big progress of destruction in case of disaster, and its detecting means are also constructed. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

The present invention relates to a solar tracking solar energy receiving device.

Conventionally, various solar energy beneficiary devices such as solar tracking solar panels have been invented (Non-Patent Document 1, Patent Document 1), but there is a problem that they often lack practical quality and performance. .
JP 2005-268671 A JP 2003-322418 A ISBN4-8277-2252-8 (Solar Tracking Device Production Guidebook)

  Although the said patent document 1 is disclosing the apparatus which tracks a solar cell panel to the sun, there seems to be an unsolved point as a practical apparatus. As for the 1st point, the power line arrangement | positioning process of a panel and an electric power supply body (house) remains unknown. Moreover, the said nonpatent literature 1 is a copyrighted work which the inventor of this invention wrote, and this inventor has produced and used the main solar tracking type solar system described in this book for many years. From this implementation experience, for example, as described in photographs 2-18 to 2-21 in Non-Patent Document 1, it is common to perform arrangement processing from the center of rotation to the part between the two. Estimated. However, if an arrangement process similar to that described above, which is essential for the apparatus of Patent Document 1, is to be performed, the arrangement process must be performed while avoiding the large gear (drive gear 2) provided at the essential rotation center. . If the disposing process is performed from the outside of the gear, there is a possibility that the gear is caught in the gear because it is a large gear. It is not possible to reduce the probability of entrainment by making a large gear into a small gear. This is because large gears are essential. The reason for this is that a large rotational torque is generated because the horizontal rotation drive of a heavy and large-area device is provided in the center of the device, and large gears and large rotational torque are swayed by strong winds, etc. This is because it helps prevent backlash.

  Further, Patent Document 1 has a structure in which a large gear for driving the panel is rotated by a motor with the center of the panel as the center of rotation. A geared motor is generally used as the motor. Clearances are provided between the gears of the geared motor and between the geared motor and the large gear for smooth rotation. If these total clearances are only 1 mm, a dead zone of 5 to 10 mm is generated at the outermost edge of the panel in terms of the ratio of the arm length to the rotational moment. For example, when the panel is rotated to the right by the motor and then moved to the counterclockwise rotation, the dead zone of the panel does not move for a while even though the motor is moving. That is, when the motor and gear serve as a stationary stopper for the panel, the outermost edge of the panel can move by 5 to 10 mm by an external force such as wind. The dead zone due to the clearance generated between the gears can easily move by the dead zone in the opposite direction due to strong wind, earthquake, tornado, etc. This may cause malfunction. If a malfunction occurs, it takes time to rebuild the system and the thermal efficiency is significantly reduced.

Further, mechanical noise caused by the movement of the panel through the clearance due to strong winds is noisy, damage to each tooth of the gear occurs, and the life of the apparatus is shortened. In addition, dust and sand carried by strong winds are more likely to adhere to the large gear. As a countermeasure, even if a cover is to be attached to the gear, it is difficult to install it because it is a connecting part between the rotating part and the non-rotating part.
Further, as can be seen in the above-mentioned Patent Document 2, the gear shaft 4 is made hollow, and wiring processing using the inside is also conceivable. However, in this case, not only the diameter of the gear shaft is increased, but also the gear and the shaft The mating structure becomes complicated or large, and the processing cost increases. If this patent document device is applied to a solar water heater, the pipe for supplying and distributing liquids must pass through the gear shaft. However, if this is done, the gear shaft will become larger and the rotary shaft mechanism will become larger and high-precision machining and cost will be increased. It becomes. Therefore, the types of Patent Documents 1 and 2 are not peeled off by a rotary solar water heater.

  The second point is the problem of the durability of the device, but the above-mentioned Patent Document 1 does not discuss whether it is durable. The present inventor has always considered what is required for a field-installed large-sized rotating device based on many years of implementation experience. In one embodiment of Non-Patent Document 1, the tank of the water heater is configured to rotate the sun tracking integrally with the collector panel, the drive unit is at the periphery (outermost side) of the rotating body, It has a point support structure. And the weight of the whole apparatus was as heavy as 350-400 kg. Further, the driving method of the above-mentioned patent document, that is, the method in which the center of the apparatus is supported by the center of rotation and the periphery of the apparatus is supported to move up and down, has a so-called two-point support rotation structure. In this method, a large load is applied to the two-point support portion of the large solar panel at the time of the abnormality, and the durability remains doubtful. Generally speaking, it is said that 80kg per square meter at a wind speed of 36m / s in a typhoon and 120kg per square meter at a wind speed of 44m / s. The equipment must be expensive or the panel must be downsized.

The present invention has been made to solve the problems described in the background art, and a first object of the present invention is to provide a practical solar tracking solar energy receiving device with good cost performance. The second object is to improve the quality and performance of the apparatus. The above performance and quality include durability and simplicity of equipment. In other words, if it is simple, it is difficult to break down, if it is difficult to break down, the durability will increase, and if it increases, the quality will improve.

In the above configuration, the shaft support portion may be a universal shaft support portion. If it does so, a freedom degree will increase in a shaft part.

  The following can be said as the effects of all the inventions described in the claims. Small power because the solar panel rotating body is installed obliquely and the lower part is moved relative to the installation surface by the solar tracking drive unit (the movement support means and the movement propulsion part) while the upper part is the center of rotation. It can be driven with. The central large gear found in the prior art is not required, resulting in an economical and inexpensive system. Since there is no panel azimuth rotation gear at the upper shaft rotary joint, the lead wires (electric wires and / or flexible liquid pipes) can be routed safely. Overall, the quality and performance of the entire solar energy receiver device will be improved.

  Further, in the present invention, various limitations can be released by bringing the center portion of the panel rotating body to the end portion (other than the center portion) of the panel rotating body. As a result, various examples can be constructed without changing the basic concept (design concept) as shown in the following examples. If various embodiments can be constructed without changing the basic design philosophy, common parts can be applied to different embodiments (models) in providing the device of the present invention according to various user preferences. For example, the invention in which the safety device in an emergency is operated by displacing (changing) the center of rotation of the panel rotating body using the basic technical idea of claims 3 and 4 is configured other than the basic technical idea ( For example, the three documents mentioned at the beginning) are almost impossible. This is because the panel rotation body rotation center is generally provided at the panel rotation body center, which is the case in the prior art. In this case, considerable energy is required to change the panel rotating body, and even if it can be done, the apparatus becomes very large. In the present invention, since the rotation center of the panel rotating body is configured to be easily changed, a progressive invention can be constructed. When constructing a developmental invention, it can be applied to, for example, a solar cell panel, a solar water heater or a combination thereof, and further to a solar power utilization device. For example, the safety device (Claims 13 to 16) has a common configuration. It can be added as a part. In addition, a solar cell panel or a solar water heater can be placed on the panel installation frame (see, for example, FIGS. 9 and 18). This means that parts can be shared.

<Effect of the Invention of Claim 1>
The effect described at the beginning of the effect of the invention or the effect equivalent to the effect of the invention of claim 3 is obtained. Listed briefly, including other effects. In the case of the device sun tracking rotation, a three-point support device is basically used, and one point is used as the center of rotation, so that stable horizontal rotation can be performed without wobbling regardless of whether the device is moving or stopped. Maintenance inspection is easy. It can be driven with small power. In addition, since a large gear is not required for the central rotating part, it is inexpensive. The conductor is safe. Since the liquid storage tank (tank) could be fixedly installed on the heat collector, it became possible to construct a solar-tracking natural circulation solar water heater (water heater). The collector can be azimuthally and elevationally displaced by the automatic handle function means of the collector support means (wheel). By moving the shaft rotation joint part (the one point), that is, the rotation center itself, it is possible to prevent the solar panel from moving at the time of abnormality. An abnormal (emergency) situation is detected or predicted by means of direct or indirect abnormality sensing, and the abnormal (emergency) situation is tolerated or the damage is minimized. As a result, the overall quality and performance of the solar energy receiver device are improved.

<Advantageous Effects of Claim 2>
Three-point support that solar energy beneficiary devices such as solar water heaters are installed diagonally, and the lower part is moved by the solar tracking drive unit, with the upper part of the axle tower being the center of rotation so that the upper part is supported by the axle tower Since a rotating body is constructed, a liquid storage tank (tank) is installed that is fixedly mounted on the installation surface separately from the rotation of the rotating body, and the tank is provided above the heat collection panel. A natural circulation solar water heater (water heater) can be constructed. Moreover, since the tank is fixedly provided so as to be separated from the rotating part, the above-mentioned movement propulsion part or a geared motor unit that is a central part thereof can be reduced in size. In addition, by not moving the heaviest tank in the apparatus, when the apparatus is installed on the roof of a building or the like, it is possible to reduce the load on the roof, beams, and ceiling. For example, the tank portion may be provided in a durable place with many pillars. Even if there is durability depending on the installation location, if a heavy object is rotated on the roof or ceiling, a squeak noise is likely to be generated, but this is also minimized in the invention of claim 2. Furthermore, since the rotating body can be lightened by the amount fixed to the tank, there are few failures. Maintenance is also easy. The upper surface of the tank is fixed to the installation surface above the uppermost part of the heat collector, which means that the pipe extends to the water as far as the upper surface of the tank is filled. Then water meets the requirements for natural circulation. As a result, a natural circulation type solar water heater can be constructed, so that a forced circulation device (for example, an electric pump using a motor) for forcedly circulating the liquid becomes unnecessary.

<Advantageous Effects of Claim 3>
The features of the invention of claim 3 can be summed up as a three-point support device, wherein one of the two points (the lower part) is installed and rotated, and the other point (the upper part) is set as the center of rotation. We have built a sun tracking rotator that drives one point, and is built with consideration of the weight balance between the upper and lower parts of the panel. It can be rotated horizontally. Further, the other is supported by the shaft tower so as to be rotatable and spaced from the installation surface, and the outside thereof is open, so that assembly and maintenance inspection are easy. Further, since the solar tracking drive unit is provided at the end of the installation surface side of the apparatus, it can be driven with small power. In addition, since a large central azimuth shift gear (refer to the prior art) is not required, an inexpensive system (economical) can be achieved, and the conductor (electric wire and / or flexible liquid pipe) can be safely routed. it can. As a result, the overall quality and performance of the solar energy receiver device are improved. There are other effects described at the beginning of the effects of the invention.

<Advantageous Effects of Claim 4>
The effect described at the beginning of the effect of the invention or the effect equivalent to the effect of the invention of claim 3 is obtained. To put it another way, there is a vertical rod like a shaft tower, and there is a solar energy receiver leaning diagonally on it, and the azimuth angle can be changed while supporting the upper portion of the receiver with the upper portion of the vertical bar. Since it can be constructed as a simple device that rotates the sun tracking around the vertical bar, for example, a solar energy beneficiary consisting of a vertically supported vertical bar, panel, shaft rotation joint unit, drive unit, and solar tracking sequencer The device (see FIGS. 9 and 18) can also be easily configured for portability. That is, there is an effect of simple configuration.

<Advantageous Effects of Claim 5>
In the tank-fixed solar tracking rotation solar energy beneficiary device, the rotation bent portion (FP, 3d5, 3d5 ′, FIG. 2b, etc.) of the communication pipe portion communicating the heat collector and the tank is maintained horizontally. By providing the pipe horizontal maintaining means (35C, FIG. 2b), the durability of the bent portion of the pipe can be improved. The device according to the present invention is basically an azimuth displacement type, and it is assumed that the bent portion of the pipe is basically bent while maintaining horizontal. Otherwise, the pipe bends with twisting when it is bent. If the bent portion that allows bending a large number of times includes a lot of twisting and bending, the durability is lowered. In this claim, the durability can be improved.
In this claim, it is possible to maintain the rotating bent portion horizontally by the pipe horizontal maintaining means even when a configuration is adopted in which the solar energy receiver is displaced at an elevation angle. Yes.
Furthermore, when an over-bending prevention means (35bb, SP1, SP2, GD1, GD2, GD3) is provided to prevent the communication pipe portion rotation bending portion (FIG. 2b) of the pipe level maintaining means from being bent more than necessary. The durability of the bent portion of the pipe is improved. Furthermore, when the pipe horizontal maintaining means includes a bent portion guide, it can be bent without difficulty every time when the pipe is bent, and the durability of the pipe is further improved.

<Advantageous Effects of Claim 6>
Since the shaft and the like are also used as a building which is a part of the living space, the strength of the tower is increased. Furthermore, the building is a building that covers the staircase that leads to the entrance to the rooftop. If the building includes an entrance (door) to the rooftop, the use efficiency is increased and the durability is further improved. This is because there are inevitably pillars in the stairs and the entrance / exit.

<Effect of the Invention of Claim 7>
Since the tank is installed on the above building, the earthquake resistance against strong winds and earthquakes is increased.

<Advantageous Effects of Claim 8>
The solar panel upper part connected to the shaft rotation joint part is moved up and down (being laid down) to further improve the solar energy receiver's efficiency. Further, when a natural phenomenon such as a strong wind earthquake is expected to be shaken, forcibly lowering the standing angle of the beneficiary body (lowering) makes it possible to reduce the probability of danger and improve security such as ensuring safety. For example, a typhoon blows from the side, so it will not be blown if the panel is laid down. An object is often destroyed by an earthquake because its potential energy is often high. By lowering its position (center of gravity), the probability of breaking can be lowered. Furthermore, the upper part of the rotation center of the panel azimuth rotation (the upper end position of the shaft rotation joint) can be moved up and down (by the shaft support moving means) (simply move the solar panel to stand) By laying the panel down from the predetermined position, the lower end of the panel is further away from the center of rotation. By utilizing this, if a stopper is provided there, the lower end of the panel can be held stationary, and security is improved. In addition, from the viewpoint of improving the receiving body receiving efficiency, it is preferable to set the variable length of the tower when the panel is laid down to 0.37 or less (for example, 1/3) of the maximum tower length. The reason for this is that when the length of the tower is the height of the tower from the installation surface and the upper tower is slid on the lower tower, the overlapping part (overlapping part) at the maximum length of the tower is the above value. This is because the durability and stability are lowered. This can be prevented from falling, but for that purpose, a high-strength material is required, and a strength-increasing device is required, which increases costs.

<Advantageous Effects of Claim 9>
According to the ninth aspect of the present invention, the solar panel elevation angle changing operation is simplified since the main locking with screws or the like is performed after the vertical movement of the panel in the vertical operation of the solar panel.

<Effect of the Invention of Claim 10>
In the basic structure of the three-point support panel rotating body, assuming that the optimal travel direction of the movement support means such as wheels is set at the predetermined elevation angle of the panel, if the panel elevation angle is changed, the optimal travel direction of the movement support means after the change is It will change. If the change is a little, it is possible to drive the panel while slipping the installation surface as when the vehicle turns, but if the discrepancy in the above traveling direction becomes large, the mobile propulsion unit (motor, etc.) is loaded and propelled. It becomes impossible. In order to avoid this, a panel vertical movement interlocking automatic handle mechanism is provided, and the traveling direction of the movement support means is adjusted to the azimuth displacement rotation direction as the panel elevation angle is changed. As a result, power loss can be reduced.

<Advantageous Effects of Claim 11>
The solar energy receiver is a collector of a hot liquid collector, and a tank is fixedly provided by a solar energy receiver device that allows the collector to be displaced in an azimuth angle and an elevation angle. Since the natural circulation condition is satisfied, the probability of facing the sun is increased, and the effect of the natural circulation is taken into consideration, so that the solar energy receiving efficiency is considerably improved.

<Advantageous Effects of Claim 12>
By making the shaft support portion a universal shaft support portion, (1) it can be driven even on an uneven installation surface or a slightly inclined installation surface. (2) The panel can be easily attached to and removed from the shaft. (3) Additional functions For example, when an attempt is made to add panel vertical movement, the shaft portion can be constructed with a simple configuration. (4) Additional function For example, when a shaft support part moving means is provided, and the panel is moved to a stopper means for ensuring safety in the event of an emergency by moving the panel, the universal shaft There is an advantage that it is not necessary to break the shaft. When the effect (2) is further added, it is possible to construct a simple solar tracking rotating solar energy receiver device that can be installed in a base camp such as a probe or a survey team. For example, a rod-shaped shaft or the like is inserted deeply into the snow surface where the snow surface is appropriately flattened. Since the head portion is, for example, the universal shaft support portion of FIG. 18, the panel only has to be fitted with the shaft portion mounted thereon. Since the installation surface of the lower end of the panel is a snow surface, the wheel as the movement support means is inappropriate, and if the wheel is attached, the movement support means is made by wearing slip shoes on the wheel. Or, replace the sliding shoes with wheels. As the movement propulsion unit, the wheel corresponding unit is driven by an impact driving unit driven by an object collision energy device using a hammer action effect including a hammer and an energy storage spring. When driving the hammer and when separating the hammer from the collision part, the energy is stored in the spring. 1: A large number (for example, 2 to 1000) is set, and a mechanism for intermittently driving the hammer is constructed to promote the movement. Part. For example, if one stroke rotates once, 15 strokes rotate 15 degrees. If this reaches the target of 15 degrees with 12 pulses, it can be stopped with 12 strokes. If the system is moved by a predetermined angle in such a system, a stopper pile that pierces the snow surface with a stopper pile that does not slide may be additionally provided on the lower surface of the movement support means. Naturally, the stake is automatically pulled out just before moving. In this way, when the solar energy receiver device is constructed in a simple portable type, the universal shaft support portion can rotate the panel azimuth angle without any trouble even if there is some unevenness on the snow surface. Therefore, in such a situation, the ease of assembly is combined and the universal shaft support will be an essential requirement.

<Advantageous Effects of Claim 13>
According to the thirteenth aspect of the invention, the stopper means can prevent the solar panel from floating from the installation portion (installation surface) due to a natural phenomenon such as a strong wind earthquake. In this case, the stopper means may be composed of a stepped portion where the STP contacts the lower surface of 901. If the stepped portions are two stepped portions separated by a predetermined distance from the lower portion of the panel, the stop effect is further exhibited. The stopper means may comprise ST7 and STT in FIG. The stopper means may be constructed by an axis moving means for generating a gravitational wedge effect and / or its control means.

<Advantageous Effects of Claim 14>
In the invention described in claim 14, since the shaft rotation joint portion can be moved by the shaft support portion moving means, and when the movement is executed, a fixing means for stopping and immobilizing the solar panel rotating body is provided. When an emergency due to a natural phenomenon is imminent, or during that time, the solar panel rotating body can be prevented from shaking or moving to improve security.

The following is a supplementary explanation that is added as an aid to understanding the concept. There are roughly two ways of operating the shaft support moving means. One is performed manually, and the other is performed automatically. In manual operation, the lever is operated, and the position of the rotary joint portion of the panel is changed during the operation. At this time, there is a method of horizontally moving without panel elevation angle displacement, but if the displacement for reducing the panel elevation angle is accompanied during the manual operation, the operation becomes extremely easy. Only the operation of releasing the fitting from the state where the panel is maintained at a predetermined angle is performed, and thereafter, the panel is displaced by the gravity dropping action of the panel itself. In the automatic operation, an operation for releasing the fitting is automatically performed. For this purpose, an initial displacement of the panel itself due to a natural phenomenon is detected and used as a trigger, or predetermined information such as an earthquake early warning is received or detected. Move. After that, as in the former case, the panel is displaced by the gravity dropping action of the panel itself, and the fixing means acts.
That is, the invention according to claim 14 includes that the fixing means is a fixing means fixed by a gravity wedge mechanism, and the fixing means has a large swing due to the effect (described later) of the gravity wedge. The larger the wedge, the more the wedge will bite in, and it will be able to withstand strong shaking.
Further, in the invention described in claim 14, the shaft support portion is a universal shaft support portion, and the distance from the lower portion with respect to the installation surface is a natural phenomenon, during solar tracking of the solar panel rotating body or An invention comprising a detecting means for detecting that it has become longer than when stopped, driving the shaft support moving means by the output of the detecting means, and fixing the solar panel rotating body by the fixing means With this configuration, further automation can be achieved.

<Advantageous Effects of Claim 15>
The invention according to claim 15 drives the shaft support moving means by the output of the detecting means for automatically detecting and detecting an abnormal phenomenon that is expected to be abnormal, and the solar panel rotating body is driven by the fixing means. Since it is fixed, it is possible to provide a solar energy beneficiary device with high security equipped with a fully automatic abnormal lock system.

<Advantageous Effects of Claim 16>
Since the solar panel rotating body can be fixed by the fixing means by receiving or detecting real-time earthquake information, it is possible to provide a highly secure solar energy beneficiary device equipped with a fully automatic abnormal lock system.
In the inventions according to claims 15 and 16, the shaft support portion may be a universal shaft support portion. Because the degree of freedom increases.

A plurality of embodiments will be described below. However, in describing the plurality of embodiments, the portions denoted by the same reference numerals and the same reference numerals basically indicate the same portions, and therefore only one embodiment is described. In some cases, the explanation is limited. The embodiment may be referred to as an example. “A and / or B” means “A and / or B”. The "shaft rotary joint part" is a simple shaft body structure composed of a bearing part and a shaft part. The shaft body includes the shaft body and the peripheral part of the shaft body (an azimuth angle and elevation angle displaceable shaft body, and the shaft body itself is collapsible. May also be included).

<First Embodiment>
The first embodiment will be described with reference to FIGS. FIG. 1 is a side view of a solar tracking solar energy receiving device, which shows the main part of the solar device viewed from the east to the west during south and middle times. The solar energy receiver device is described as a solar water heater in this embodiment, but may be a solar cell panel. In that case, you may exclude all parts (for example, a tank, a connection pipe, etc.) unnecessary for a solar cell panel. Assuming that the apparatus is a water heater, a heat collector 10 which is the main part of the solar water heater is installed on a pedestal frame 11 and is collectively referred to as a collector panel 1. Since the collector panel 1 is supposed to rotate and track the sun, it is also called a solar panel rotating body. In this embodiment, the collector panel 1 is horizontally rotated so as to be movable in the azimuth direction, and can be moved so as to be swingable in the elevation angle.

FIG. 5 is a rear view of the collector panel 1 viewed from e in FIG. FIG. 6 is a plan view in the F direction when FIG. 1 is viewed from the top to the bottom, showing the entire apparatus of the first embodiment, and the communication pipe 4 and the like are omitted. Note that FIG. 6 is drawn assuming that the panel 1 of FIG. 1 faces east. FIG. 7 is a first embodiment of FIG. 1 viewed from the upper left to the lower right and viewed from the front to the back of the paper, and is a perspective view in which the collector panel 1, the communication pipe 4, and the tower 2 are not shown. FIG.

  In this embodiment, the collector 10 which is a main part as the collector panel 1 having the pedestal frame 11, the tower 2 having a predetermined height fixed to the horizontal installation surface 9, and the panel 1 are driven. The motor drive unit MDU which is a main part as a sun tracking drive part (movement propulsion part) is provided. The heat collector 10 may be a commercially available rectangular heat collector (for example, two 1500 mm × 1000 mm × 65 mm), or a trapezoidal heat collector when the panel surface is viewed vertically. . As the rectangular heat collector, a collector panel 1 is obtained by mounting and fixing a plurality (for example, two / 10a, 10b) of the heat collectors 10 on the pedestal frame 11 and combining them (particularly FIG. 4, see FIG. The pedestal frame 11 is composed of a metal cross-section L-shaped angle member (frame) having the same outline as or slightly larger than the rectangular heat collector 10, and has a shape in which the plan view “N” is a mirror symmetrical configuration. ing. The diagonal bracing frame 11e is a deformation preventing frame. The deformation preventing frame may be an X type (11e, 11f, 11g, 11h).

  The sun tracking drive unit includes a motor drive unit MDU and a drive system (a sun tracking command unit including an electronic circuit or a microcomputer) which will be described later. The tower 2 includes a tower tower 21 as a lower part of the tower and a tower main body 22 as an upper part of the tower 2 slidably mounted thereon. The vertical slidable mechanism will be described in detail later, but the description will be continued assuming that both are held in a fixed relationship.

  The panel 1 includes rotating wheels 16 and 17 for rotating the panel 1 horizontally and smoothly on the installation surface 9 in the vicinity of both sides AA and BB on the installation surface side one end portion 11a of the pedestal frame 11. That is, the lower ends AA and BB of the legs 12 and 13 fixed at one end to the frame 11c and the frame 11d connecting the upper end frame 11b and the lower end frame 11a and fixed at the other end to the braces 11g and 11h. The mounting seats 14 and 15 and the leg bodies 12 and 13 are pivotably attached. The legs 12 and 13 are welded to the illustrated position across the auxiliary frames 11g and 11h and the left and right frames 11c and 11d. The other end (upper end) 11 b of the pedestal frame 11 is connected and connected to the tower main body 22 of the tower 2 via the connecting part 3 and the rotating shaft body 30. The connecting portion 3 is formed of a hinge member in which both wing portions (3a, 3b) are rotatably coupled via a shaft portion 3c, for example. By fixing one wing 3a of the hinge member to the center lower part (lower surface of the L-shaped angle) 11bb of the other end 1b of the frame 11 and the other 3b of the wing to the horizontal peripheral end 32a of the rotary shaft 30, 1 and the rotating shaft 30 are connected. The shaft tower main body 22 is provided with a rotating shaft body 30 (+) connected to the connecting portion 3 so as to be horizontally rotatable. The rotating shaft body 30 is configured by a side-view handle made of metal and has a long shaft portion 30a as a shaft body corresponding to the handle portion, and an upper end portion 33 and a lower end portion 34 thereof are welded to the tower main body portion 22. The triangular plate is attached rotatably to bearings BJ1 and BJ2 provided on the horizontal upper end 22a and the horizontal lower end 22b, respectively (see also FIG. 3).

The bearing parts BJ1 and BJ2 are bearing bearings, and the lower bearing part BJ2 uses a downward movement prohibition stopper specification bearing. The flange portion 32 of the rotating shaft body 30 includes a vertical portion 32b as an outer portion of the shaft body, a horizontal arm portion 32c, a grip portion (long shaft portion) 30a corresponding to a base portion of the handle portion 30a, and a peripheral portion (32b, It consists of stay members 36 and 37 as reinforcing portions that hold 32a) indeformably. The stay member 37 has one end welded in the vicinity of the horizontal peripheral end portion 32a and the other end welded and fixed to a stay member 36 that is bridged and fixed to the horizontal arm portion 32c and the long shaft portion 30a that is a holding portion. Become.

With the above configuration, the panel 1 is configured to maintain an oblique placement state in which the panel 1 is placed obliquely with respect to the installation surface 9. The panel 1 is rotated in the obliquely mounted state via the shaft body 30 so as to track the sun. The reason why the rotating wheels 16 and 17 are attached to the one end portion 1a deeper than the one end 11a of the collector panel 1 is that the shaft tower 2 moves up and down when the panel, which will be described in detail later, can be swung at an elevation angle. This is to increase the elevation angle swing range while suppressing the movable distance. In this embodiment, the rotating wheels 16 and 17 are attached via the legs 12 and 13 and the mounting seats 14 and 15 at about ３ of the vertical length (total panel length). The motor drive unit MDU is attached to the one leg, for example, the leg 13. This unit is a geared motor composed of a motor and a gear, and is connected to one wheel 15.

When the collector panel 1 is a hot water collector (a solar cell panel may be used, but the following tanks and pipes are not required), a tank (hot water tank) 5 is provided above the collector. And a communication pipe portion 4 through which water circulates between the heat collector and the tank 5 (see particularly FIG. 4). The tank 5 is mainly composed of struts 61, 62a, 62b, 63a, 63b extending in the vertical direction, oblique stages 61a, 61b, 63c, 63d, 64, 65, 68a, 68b and horizontal frames 61c, 61d, 67a, 67b. , 67c, 67d, 63e, 63f and 69, and is screwed onto a tank holding portion 69 which is one of the horizontal connection frames with screws (not shown). (See FIGS. 1, 5 and 6). The tank holding part 69 is composed of a rectangular frame and a ladder part, and is composed of, for example, an L-shaped angle member. When viewed from above, it forms the shape of an “eye” as a whole. There may be one or many horizontal bars (ladder portions) of the eyes. Each frame has a number and is not shown, but it should be understood that it is a hidden frame provided oppositely. For example, 68b is a hidden frame paired with 68a.

The support 61 is fixed at the middle of the upper ends of the oblique stays 61a and 61b, and the lower end of the support 61 is fixedly connected to the lower end of the support 61 via the horizontal connection frames 61c and 61d. The lower ends of 61a and 61b are installed on the installation surface 9, and are fixed to the installation surface with screws (not shown). The inner lower end portion of the support column 61 and the inner lower end portion of the stay 65 are connected and fixed, and the upper end portion of the stay 65 and the intermediate portion (center portion) of the ladder stay 69f of the tank holding unit 69 are connected and fixed. 61 and the north-south direction of the tank 5 are prevented. Further, the center portion of the ladder stay 69e of the tank holding portion 69 and the upper end portion of the support column 61 are welded or screwed together to connect and fix the connecting portion to the upper end portion of the stay 64, and the lower end portion of the stay 64. By connecting and fixing the intermediate portion of the frame 67c, the anti-glare prevention in the north-south direction is further strengthened. In addition, when the cross points of the stays 64 and 65 are screwed with the screw n1 or the like, the seismic strength is further increased.

The horizontal frame 67 constitutes the main part of the base part of the rectangular tank mount 6 composed of the east, west, north and south frames 67a, 67b, 67c, 67d. The vertical pillars 62a, 62b, 62c, 62d are vertically suspended from the joints at the four corners, and the tank holding part 69 is fixed thereon. Casters ca2, ca3, ca4, and ca5 are provided on the lower surface of the joint portion. A caster ca <b> 1 is also provided on the lower surface portion of the column 61. An appropriate reinforcing diagonal step (for example, an oblique step 68a between 62a and 63a) is provided between the adjacent columns 62a to 63b. A diagonal step 68b is also provided on the opposite side. The frames 63e and 63f are provided as deformation preventing frames in which the lower ends of the support columns 63a and 63b and the oblique steps 63c and 63d are connected to each other.
The tank mount 6 configured as described above is configured to support the tank 5 substantially at one point on the south side and four points on the north side. The column 61 of the tank gantry 6 also plays a role as a tower support part that supports the shaft 2 and the like vertically.

As shown in FIG. 3, the tower 2 is an attachment part provided at the upper end and the lower end of the tower base 21, either via the tower 2 or the column 61 or via a spacer SP <b> 1 provided as an intermediate member. Then, it is fixed to the support 61 by screwing means (not shown). When the tower 2 is fixed to the column 61, the rotation center of the collector panel 1 is located slightly north of the column 61, and is a position indicated by “O” in FIG.

In this embodiment, since a solar water heater is assumed as a solar energy receiver device, a liquid connection pipe 4 between the collector panel 1 and the tank 5 is required. Although details of the pipe 4 will be described later, the rotation center “O” is preferably provided outside the panel 1 so as not to overlap the panel 1 because the pipe 4 is required. If this is provided on the inside, there is a merit that the rotation radius of the panel is reduced and the installation area of the entire apparatus is reduced, but the processing of the connection pipe 4 becomes complicated and the pipe length must be increased, When viewed from above, the overlap between the tank and the panel becomes deeper, and the disadvantage is that a natural circulation water heater cannot be realized. Therefore, as the water heater system, the rotation center “O” is preferably outside the panel 1. However, it can be said that the demand is larger when the installation area of the entire apparatus is made as small as possible. Therefore, in this embodiment, the center of rotation is provided outside the panel 1 but is made as close to the panel 1 as possible. According to consideration, even if the distance D1 between the panel 1 and its rotation center “O” is about 10 cm (10 to 20 cm), the heat exchange efficiency is not lowered, and the cost is not increased as much as possible. As shown in FIG. 6, the tank 5 is installed so as to be long from north to south.

This tank 5 may be a set with a commercially available water heater panel, and the tank may be custom-made. In the case of the commercial case, as shown in FIG. 6, when the panel having the same length in the longitudinal direction and the length in the tank longitudinal direction is used (not necessarily equal), when the panel 1 is facing east or west, You may install so that the upper north side may overlap a tank a little. Even if it does in this way, compared with the thing which does not overlap, heat conversion efficiency hardly falls. For example, assuming that the short direction length DS of the tank 5 is 50 cm and an overlapping portion of 15 cm is provided, DS = 15 + 10 + 10 + 15 = 50 (cm). When the sun is tilted east or west, its altitude has dropped considerably, so the 15cm overlap is a vertical overlap, and when the sun's altitude is low, the tank and the panel Does not overlap the surface. Therefore, efficiency does not fall. When traveling south and south, the tank's short direction and the panel are confronted, and even in the summer solstice, the altitude is around 78 degrees in Japan. Because it gets hot, there is no problem. The above numerical value is an example, and it may be calculated in consideration of the vertical position of the tank and the panel. FIG. 1 may be an elevation angle fixing method, and the above numerical example may be seen as a numerical value when the tank and the panel are provided closest to each other (both vertical intervals are 10 cm). In FIG. 1, the elevation angle shift method is used, and the vertical separation distance is 20 to 60 cm, and the horizontal distance D1 between the rotation center “O” and the panel 1 is intended to be about 20 cm.

From the above consideration, in the east-west direction of the panel 1, the panel 1 and the tank 5 are provided so as to overlap in the vertical direction, and the distance D1 between the rotation center “O” and the panel 1 is at least about 1 cm in the radial length of the communication pipe 4. It can also be said that it is possible within a range that hardly reduces the efficiency. The thickness in the east-west direction of the slanted stages 64 and 65 at this time must be configured to be equal to or less than the diameter of the communication pipe 4.

In the space other than the overlapping portion of the tank 5, the base portion main portion 67 of the tank mount and the vertical column 62 are disposed. There are two reasons for providing such a hook-shaped portion. Generally, the weight of the tank 5 is 150 to 200 kg when filled with water, and close to 300 kg when it becomes large. One is that it has an earthquake resistant structure that can withstand strong winds and earthquakes as much as possible, and the other is that the sub tank ST can be placed between the bottom of the tank 5 and the main part 67 of the base. is there. The sub-tank ST represents the sub-tank detailed in P93 of the non-patent document written by the same inventor of the present invention as a structure as shown in FIG. This structure (FIG. 7) itself is novel. In other words, whatever the method, the solar tracking water heater has been proven in the non-patent literature that it becomes hot in the morning, and it is a sub-tank for storing the hot water as stock until it is used. . The sub-tank ST is inserted and arranged in the tank frame from the back of the page, that is, from the north side through the columns 63a and 63b. When the tank 5 is a main tank, the capacity of the main tank and the capacity of the sub tank are set to be the same or slightly smaller in the sub tank ST.

As shown in FIGS. 1 and 4, the communication pipe portion 4 is directly connected to a hot liquid inlet / outlet portion 41 provided on the upper end wall 1 bb of the heat collector 10 and an elbow portion 42 provided continuously to the inlet / outlet portion 41. A flexible pipe part 45 that connects a fixed (non-flexible) pipe part PS composed of a pipe part 43 and a T pipe part, and an L-shaped connecting port 48 fixed to the fixed pipe part PS and a hot water tank (tank) 5. 47 and the communication port 48. The flexible pipe portion 45 includes a regular short L pipe 46 for convenience. The inlet / outlet portion 41 is composed of cold water intake ports 41a and 41d (not shown) and hot water outlet ports 41b and 41c of the two collectors 10a and 10b provided side by side. The elbow portion includes elbow portions 42a, 42b, 42c, and 42d (not shown) that connect the straight pipe portions 43 and 41 to each other. In addition, 42e, 42f, and 42g are also elbow parts. T pipe parts 44a, 44b for separating or joining the fluids of the collectors 10a, 10b and the inlet / outlet 41 are connected by the elbow part 42 and the straight pipe part 43 to form the non-flexible) pipe part PS. is doing.

The cold water flowing into the flexible pipe portion 47a from the tank 5 through the communication port 48a falls in the order of the flexible pipe portion 47a, the elbow pipe portion 46a, the flexible pipe portions 45ba, 45ca, 45aa, and the cold water flowing into the T pipe portion 44a Here, the water is branched into straight pipe portions 43a and 43d, and enters the heat collectors 10a and 10b from the inlet 41a and the inlet 41d. The hot water heated by the heat collector rises from the outlets 41b and 41c through the elbow parts 42b and 42c through the straight pipe parts 43b and 43c, and through the elbow pipe parts 42f and 42g to the elbow parts from the straight pipe parts 43e and 43f. 44b, and flows upward from the communication port 48b to the tank 5 through the flexible pipe portions 45ab and 45bb, the elbow portion 46b, and the flexible pipe portion 47b. The flexible pipe portion 45 is guided by a guide member 35b that is slidably guided in the longitudinal direction of the pipe and is not deformed in the azimuth direction. It is defined between the pipe parts 45ba and 45bb which are guided by the azimuth non-deformation restricting part 61g formed by a long hole part and can extend and contract the pipe up and down, and between the guide member 35b and the restricting part 61g. It consists of pipe parts 45ca and 45cb. Pipe portions 45aa, 45ba, and 45ca are pipe portions for injecting cold water into the heat collector, and pipe portions 45ab, 45bb, and 45cb are pipe portions for inflowing hot water into the tank.
In addition, although the elbow pipe part 46 is an elbow pipe part which united 2 input 2 output in order to prevent variation, you may comprise separately.

The fixed pipe portion PS from the inlet / outlet 41 to the T tube portion 44 is fixed to the upper side portion 11ba of the L-shaped cross-section frame 11 on which the heat collector 10 is placed and fixed in order to fix the pipe portion PS to the fixed shape. Pipe holding portions 18 and 19 fixed by screws SC1 or welding are provided. The fixed pipe portions PS are fixed to the panel 1 by fixing the straight pipe portions 43 a and 43 d to the pipe holding portions 18 and 19. The T tube portions 44a and 44b are also held in a fixed relationship by a holding portion (not shown). Of the flexible pipe parts, the pipe part 45 is bundled by members (not shown) so that 45a and 45b can move in the longitudinal direction.
The fixed pipe portion PS is formed of a rigid body such as a double molded product of vinyl chloride or metal and resin. The flexible pipe 45 and the flexible pipe 47 are formed by coaxially forming a central pipe material made of polypropylene or the like and a covering portion made of a mesh-like stainless steel protective material, and are divided into a first connection portion and a second connection portion. The The pipe 45 serving as the first connection portion is detachably held by a tunnel-shaped guide member 35b provided near the panel on the upper surface of the horizontal top plate 35a fixed to the upper end 33a of the shaft main body 33 of the rotary shaft 30. .

As shown in FIG. 2, the top plate 35a has a shape such as a keyhole shape in a plan view or a front rear circular ridge, and a guide member 35b is fixed to a tongue-like tongue-shaped portion 35aa protruding from the circular portion. The top plate is formed of two upper and lower layers, and the top plate 35a interlocking with the rotary shaft 30 is a lower layer top plate, and a circular top plate 35c rotatably attached to the upper surface is an upper layer top plate. The upper surface of the tongue-shaped portion 35aa and the upper surface of the upper layer top plate 35c are formed to be the same surface.

The elbow pipe portion 46 is when the first connecting portion 45 and the second connecting portion 47 are in the vertically approaching state as indicated by the solid line in FIG. In order to prevent the pipe itself from undergoing excessive deformation (deformation that cannot be elastically recovered), an angled portion is provided. If the distance between the lower surface of the tank and the upper surface of the top plate 35a is designed not to approach too much when both approach, the first connecting portion and the second connecting portion can be integrated with each other. You may comprise.
Further, in order to prevent the horizontal fluctuation of the flexible pipe portion (second connecting portion) 47, two partial arc-shaped regulating members (guide members) 691 and 692 are indicated by dotted lines on the lower surface of the ladder portion 69e of the tank holding portion 69. In this manner, the holding portion 69 and the support column 61 may be fixedly provided. When the tower 2 expands and contracts vertically with respect to the axis, the pipe of the first connection portion 45 is held by the guide member 35b so as to be freely inserted and moved, and the length as the restriction member The holes 61g are guided so as to be able to be put in and out and bendable, and their positions are regulated.

In general, the flexible pipe material is made to be resistant to “bending”, but is not very durable against bending involving twisting. Therefore, it is desirable that the “flexible pipe bending mode” is always repeated without causing excessive deformation in the same way during vertical movement and azimuth movement. The number of years is shortened. Therefore, if a guide function unit that guides bending so as not to cause “over-deformation bending” is provided as shown in FIG. 2B, the service life can be extended. The configuration will be described next.

The gondola portion GD is fixed with a screw N35 at a position closest to the column 61 of the upper layer top plate 35c. The gondola portion GD is a functional member having a pipe bending guide function and a function to prevent the pipe from moving up and down. The gondola portion GD has a reverse U-shaped main body portion GD1 in front view and a U-shaped guide support arm portion GD2 having a counter structure. GD3, two upper and lower pulley parts PR (the lower pulley is not shown) that make a smooth movement when moving up and down, and a pulley that rotatably supports the pulley part PR and that is continuously connected to the main body part GD1 The support portion GD4 and the elastic slide member GD5 that always elastically presses the pulley portion PR against the end portion of the long hole 61g provided in the column 61 and also presses itself. The slide member GD5 has an oval ring shape, and includes slip prevention protrusions GD7 and GD8 that protrude in the pressing direction from a contact portion GD6 that contacts the end face of the long hole 61g. The guide member 35bb is fixed to the upper surface of the tongue-shaped portion 35aa with four screws 356, 357, 358, and 359. The guide member 35bb includes two long leaf spring portions SP1 and SP2 that pass through the upper surface of the upper top plate 35c and face both inner sides of the gondola main body GD1. The front ends of the leaf springs are each bent outward. In the illustrated state, the tongue-shaped portion 35aa when the panel 1 faces east is represented by a solid line, and the dotted line represents a state where the panel faces the south. And two pipe parts 45 are piled up and down and inserted through guide member 35bb between two leaf spring parts SP1 and SP2 (a pipe is not illustrated).

When the pipe is bent eastward or westward as shown in the drawing, the two leaf spring portions SP1 and SP2 guide the pipe so as not to cause excessive deformation bending of the pipe. At this time, one of the spring ends, for example, in the case of facing east, the spring end ST2 protrudes from the rear end outlet end face of the main body GD1, as shown in the figure, and the other spring end SP1 (not shown) is the GD1 rear end outlet. It is locked to the end face and the pipe bend does not bulge outward. Moreover, the top plate 35a moves up and down between the solid line illustrated state with a low solar altitude and the dotted line illustrated state with a high solar altitude in FIG. At this time, the top plate 35a rotates in the azimuth direction in synchronization with the panel 1, but the top plate 35c is made stationary by the gondola GD by making the top plate 35a and the top plate 35c rotatable. . The top plate 35c is movable up and down. Further, the top plate 35a keeps the top plate 35c horizontal when the azimuth angle changes, and keeps the flexible pipe portion 45c always horizontal when moving up and down and when changing the azimuth angle, while keeping the vertical position substantially the same as the pipe portion 44. ing. At the time of vertical movement, the top plates 35a and 35c move up and down in conjunction with the vertical movement of the tower 2 so that the gondola portion GD moves up and down. In order to ensure the smoothness of the GD vertical movement at this time, the upper and lower pulleys PR, PR rotate, and the GD 6 slides with respect to the support 61.

In the embodiment of FIG. 1, the pipe is regulated by the regulating member 35b or 35bb, but the subsequent portion near the tank has a structure that can be bent while allowing a predetermined bending radius. That is, the communication pipe 4 is regulated by the regulation part 61g or the GD1 following the guide member 35b. The regulating portion 61g or GD1 enables the pipe to move in the north-south direction. As a result, a large bending with a small radius of curvature is not concentrated on one place. In other words, the top plate 35c has a horizontal disk shape, and the pipe is placed horizontally on the disk, so that the end portion, that is, the angled portion 44 and the vicinity of the connection port 48 are not over-curved. In order to protect it, the guide member and the restricting member guide the way of bending. This improves the durability of the pipe 4. In addition, the flexible pipe portion located between the regulating portion 61g and the elbow portion 46 is also in an approaching state to the tank 5 (see FIG. 2) by the horizontal plate 229 fixed to the upper portion of the tower main body portion 22. The horizontal state can be maintained. That is, since the horizontal plate 229 is attached to the tower main body 22 via the triangular reinforcing portion 228 so as to be flush with the top surface of the top plate 35C, a drop portion (described later) does not occur due to slack. .

Further, since the top plates 35a and 35c need only support the communication pipe 4, they may be made of a stainless plate having a thickness of about 1 mm as shown in FIG. In addition, as shown in FIG. 1, the configuration in which the contact position of the pipe 4 guided by the guide members 35b, SP1, and SP2 is gradually changed by the vertical movement of the panel 1 is also an element that avoids the generation of one-point stress. ing. Further, when the panel 1 is laid down, the effective length of the pipe 4 from the member 35b to the connection port 48 increases corresponding to the rate of change in the elevation angle of the panel, so it is necessary to increase the pipe length to absorb “bending”. You don't have to. That is, “single-point concentrated bending” can be avoided without increasing the length of the pipe, so that the durability is increased, and in addition, the pipe length can be shortened.

Therefore, from the above configuration, in this embodiment,
1) It can be constructed as a variable azimuth system that rotates about 180 degrees from east to west by fixing the elevation angle of the panel.
2) It can be constructed as a two-axis variable system that changes the elevation angle while changing the azimuth angle of the panel.
3) The elevation angle change of the panel can be constructed as a system that changes to a low angle close to the horizontal when there is an abnormality such as an earthquake typhoon tornado. Assuming that the angle (inclination angle or elevation angle) formed by the panel with the horizontal plane is i, the wind pressure received by the panel becomes sin (i) times as much as the panel is nearly horizontal, and it is safe because it is weakened accordingly. Furthermore, even if damage occurs in an earthquake and the fragments fall on the installation surface, the potential energy is small, so that the damage can be reduced even if the installation surface is a roof member.
4) The elevation angle change of the panel can also be constructed as a moving system (described later) for locking the panel when all the above abnormalities occur.

In any case, the elevation angle of the panel is changed by sliding the tower main body 22 so as to be slidable up and down with respect to the tower base 21 having a predetermined height. For example, when the shaft tower is mainly constructed of a metal L-shaped angle, the rotating shaft is composed of an upper position holding triangular plate 22a and a lower position holding triangular plate 22b as shown in FIGS. The pulleys P1, P2, P3, P4, P5, and P6 are rotatably attached to the respective corners of the triangular tower base 21 so that the shaft tower main body 22 on which the body 30 is rotatably held is mounted. Holds vertically slidable. As shown in FIGS. 1 and 3, the pulley is provided with three places on the top of the shaft tower base 21, pulleys P1, P2, and P3, and three places in the middle, and pulleys P4, P5, and P6. The pulleys P1 to P3 are pulley support portions at three corners of the hollowed triangular member 21c of the central hollowed triangular member 21c having a thickness of 3 mm that is welded or screwed to one support portion 21a of the horizontal section L type of the shaft base 21. As shown in the figure, it is rotatably mounted via PR1, PR2 and PR3. The pulleys P4 to P6 are also attached to a triangular member (not shown) similar to the above at the intermediate portion in the same arrangement as described above.

The other support portion 21b is integrally formed as the base portion 21 by screwing and holding the lower bent portions 21c1 and 21c2 from the triangular member with screws or the like. The support portions 21a and 21b are screwed with screws or the like (not shown). A rack gear SR is attached to the entire upper and lower surfaces of one outer wall portion 221 of the L-shaped angle. A bearing portion JR is provided at a portion of the shaft tower base portion 21 located in an intermediate portion (see FIGS. 1 and 3) between the upper pulley and the lower pulley so as to confront this, and fitted and attached to the bearing portion JR. Further, the gear-integrated type corresponding shaft J1 is rotatably held by the bearing portion. The gear G1 is driven by the geared motor GM, and is rotated in conjunction with the rotation of the shaft J1. The geared motor GM is fixed to the outer wall portion 221. When the geared motor GM is driven, for example, the tower main body 22 moves downward from the uppermost position in FIG. 1 while being guided by a total of six pulleys P1 to P6. When the tower body 22 moves downward, the connecting part 3 moves so that the angle of each hinge part opens, and the angle of the panel changes so as to lie down. At the same time, the angled part (elbow part) 44 of the pipe rotates clockwise in FIG. 1 with the axis 3c as the center of rotation, so that the bending of the pipe is eased while extending the effective length of the pipe from the member 35b. The tank 5 and the top plate 35a are separated from each other (see the one-dot chain diagram in FIG. 1). When the tower main body 22 moves upward, each part moves in the opposite direction to the downward movement.

In this embodiment, it is considered as a solar tracking type solar water heater capable of both azimuth rotation and elevation angle shift, and the heating method is based on a natural circulation method. The more efficient structure for that is described above. That is, it is considered that the drop portion in the communication pipe 4 does not occur anywhere from the minimum elevation position to the maximum elevation position of the panel. This drop part means that it becomes S character or U character in the up-and-down direction. The larger this drop part, the lower the thermal efficiency of natural circulation. Increasing the diameter of the communication pipe is more efficient, but if the pipe diameter is increased and a drop occurs, the air bag may remain at the top of the S-shape when entering the water. . In addition, at the initial stage when natural circulation begins to occur, the drop portion may be a factor that prevents circulation of hot water and cold water. For example, at the initial stage, hot water rises into the tank while hot water and cold water mix in the pipe. It is difficult for the mixing at this time to occur in the drop. Also in this respect, it is better to have a structure in which the drop portion is less likely to occur. There is a place where some pipes 4 are horizontal at the maximum elevation position, but if it is horizontal, the hot water will be on the top and the cold water will be on the bottom. Therefore, the cold water mass accumulated in the oblique portion moves the horizontal cold water mass in the opposite direction to the hot water, so that the efficiency at the initial stage is hardly lowered. Once the hot water pipe is filled with hot water and the cold water pipe is filled with cold water, the circulation proceeds smoothly.

In this embodiment, the collector panel 1 is constructed as a structure capable of performing the rotation for changing the azimuth angle and the (motor) rotation for changing the elevation angle simultaneously or individually. As for the elevation angle changing method, a method is used in which the diagonally upper portion 1B (one side), for example, the upper end portion 1b is moved vertically up and down, and the lower portion 1A (the other), for example, the lower end portion 1a (precisely, the wheels 16, 17) is moved horizontally. I'm taking it. Accordingly, the rotational radius of the azimuth angle change rotation, that is, the trajectory Rt of the wheels 16 and 17 changes with the elevation angle change. When this change occurs, it is necessary to match the traveling direction of the wheels along the trajectory. The slight discrepancy is forced to the shaft center “O” with “slip”, so the rotation can be continued, but the big discrepancy increases the friction between the wheel and the installation surface and accelerates the wear of the wheel and motor drive system. Not only can it run. Therefore, this embodiment is further improved. It adds a “elevation angle shift interlocking wheel direction changing system (mechanism)” that changes the traveling direction of the wheel in conjunction with the elevation angle shift. The mechanism will be described with reference to FIG. 1, FIG. 5, FIG. 6, and FIG.

An inverted Y-shaped interlocking bar (interlocking member) YB that moves up and down with respect to the panel and moves in the wheel mounting direction is provided below the panel. The interlocking rod YB includes a clog-type interlocking rod bearing member RC1 fixed to the lower surface of the horizontal peripheral end portion 32a of the rotary shaft 30 with a screw SC5 and sliding holding members RC2, RC3, RC4 fixed to the panel 1. RC5 and the wheel rudder parts rd1 and rd2 attached to the wheel attachment seat 14 are slidably attached (FIG. 8). The slide holding members RC2, RC3, RC4, and RC5 that slidably hold the interlocking rod YB are screwed to the frame 11 with screws (SC2 for RC2) as shown by RC2. A through hole (long hole h8 long in the panel front and back direction) through which the interlocking rod can slide is provided in the longitudinal direction, and the interlocking rod can be penetrated through the through hole to be slidable. The upper end portion YB1 of the interlocking rod YB is a T-shaped shaft portion Y1, and forms a rotating shaft structure in which the horizontal end is fitted into the shaft holes of the clog teeth rb1 and rb2.

FIG. 8 is an operation and structure diagram for explaining the elevation angle shift interlocking wheel direction changing system. FIG. 8A is a cross-sectional view as seen from the arrow 7A in FIG. 8B, and shows the vicinity of the upper end of the interlocking rod. FIG. 8B is a perspective view of the same part in which the collector panel 1 is omitted. For example, when the elevation angle of the panel 1 is 0 degree in the horizontal position, the solid line state in FIG. 8A represents the 45 degree position of the panel 1. The two-dot chain diagram represents the 30 degree position, and the one-dot chain diagram represents the 15 degree position. An arbitrary point P1 in the longitudinal direction (vertical direction) of the interlocking bar YB at the 45 degree position of the panel 1 is an arbitrary point for indicating what the relative position to the panel 1 will be when the angle of the panel 1 is changed to 30 degrees and 15 degrees. Is a point. For example, in order to see the relative position, attention should be paid to the holding member RC2, and the distance or position between RC2 and P1 may be focused. It can be seen that the arbitrary point P1 comes to the position of P2 and P3 when the angle of the panel 1 is changed to 30 degrees and 15 degrees. The amount of transition is the arc length represented by the travel angle with the radius of the line segment 3C-Q1 (Q1 is the axis of the upper end of the interlocking rod) (exactly the length of Q1-Q2 and Q1-Q3) ) Only change. This displacement is transmitted by the interlocking rod YB through the sliding holding portion RC3 which is the intermediate holding portion, and is bifurcated from the lower portion (for example, 3 cm below) slightly and transmitted. While the interlocking rod YB is slidably held by the sliding holding portions RC4 and RC5 fixed to the legs, the displacement is finally transmitted to the wheel steering portions rd1 and rd2. That is, by transmitting the displacement of the interlocking rod relative to the panel 1 accompanying the elevation angle change of the panel 1 to the wheel rudder parts rd1 and rd2, the traveling direction of the wheel can always be automatically corrected to the trajectory (trajectory) Rt to be originally rotated. It is like that.

Note that the intermediate holding portion of the interlocking rod YB is screwed to the illustrated position of the reinforcing frame 11i of the frame 11 by screws SC2, for example, RC2 in FIG. 8A (RC3 has the same configuration). The sliding holding members RC2 and RC3 are formed with holes through which the interlocking rod YB can slide in the longitudinal direction, and the interlocking rod YB is slidably held in the holes. Further, the interlocking rod YB lower end holding structure RC4, RC5 to the rudder portions rd1, rd2 is configured to be slightly bent immediately before the rudder portion and supported by RC4, RC5, and the tip thereof is RC1 in FIG. It is the structure connected so that it can rotate freely by the structure substantially the same (the shape of a clogs main-body part differs). In other words, the panel angle displacement is transmitted to the rudder parts rd1, rd2 by the link mechanism 32a, 3b, the interlocking rod YB supported by RC1, RC2, RC4, RC5 and the rudder parts rd1, rd2. It can be said that.

As described above, the wheels can be automatically steered with a very simple configuration. A small amount of movement for changing the direction of the wheel, for example, about 1 to 3 cm, is sufficient, and the crotch opening deformation of the interlocking rod which is an inverted Y-shaped rigid body of this degree is performed within the elastic deformation limit. It has become. For example, the interlocking rod is formed of a stainless steel rod having a diameter of 1 to 2 cm or a rigid body in which the sliding contact portion is at least resistant to rust. The interlocking rod may be a pipe-like member. Such a linear motion of the upper end portion of the interlocking rod YB is converted into an oblique inward / outward motion of the lower end portion. In the position of the panel elevation angle of 45 degrees in FIG. 8A, the moving direction of the wheel is PQ1 (see FIG. 5), whereas when the panel elevation angle decreases to 30 degrees and 15 degrees, The moving direction becomes PQ2 and draws a great circle. When the interlocking rod YB is moved downward, the crotch opening deformation occurs. The deformation is stored in the interlocking rod YB itself as a spring force. FIG. 5 shows this state. If the panel elevation angle is commanded in a small direction from here, the interlocking rod YB returns and deforms so as to reduce the crotch opening angle while releasing the spring force. In other words, since a configuration is adopted in which return deformation occurs so as to cancel out the weight of the interlocking rod, when changing the traveling direction of the wheel, the force applied to either one can be applied to the other in the same way. The handle force is not unbalanced.

In FIG. 1, an alternate long and two short dashes line connecting the tower 2 and the installation surface 9 is an imaginary line that should be referred to when designing the apparatus of the present invention. It is shown as the critical boundary that is placed. For example, the installation angles of the oblique stages 61a and 61b are configured to be the same angle as this imaginary line. The inside of the imaginary line is a space that does not interfere with the panel, the interlocking rod YB, and the like with respect to the panel rotation. Steps -260 and 270 of the second embodiment (FIG. 9) to be described later are also provided in accordance with this imaginary line. When the shaft tower is fixed to the installation surface or the base portion with screws or the like with the L-shaped tower tower installation reinforcing material connected to the lower part of the tower, or is held by the oblique stage, the shaft tower is firmly supported. . For the above reasons, the L-shaped tower installation reinforcing material and the tower installation holder such as the oblique stage can be provided within the critical boundary line.

Therefore, in addition to the configuration of claims 3 and 4, etc., a shaft tower installation holding part is provided, and the panel side is challenged (protruded) from a position suspended from the shaft part of the other end part (upper part) of the solar panel rotating body. The invention in which the shaft tower installation holding part is provided can also be disclosed here. This configuration also includes an invention in which the lower part of the tower shown in FIGS. 14 and 19 is formed of a building. With this configuration, a strong shaft or the like can be configured. Further, the above-described configuration includes a configuration in which the shaft tower installation holding portion is configured with legs that extend radially from the shaft tower (see FIG. 9 and later).

<Second Embodiment>
Next, a second embodiment will be described with reference to FIGS. FIG. 9 is a side view of the solar tracking solar energy receiver device. The solar energy receiver of the device is a solar cell (photovoltaic power generation) panel 10S, and the panel 10S is rotated in the horizontal direction so that the azimuth is movable, and the elevation angle is freely swingable as in the previous embodiment. It can be moved. FIG. 10 is an exploded perspective view of the main part of the tower 20. FIG. 11 is a horizontal sectional view of the tower 20 as viewed from above in FIG. FIG. 12 is a perspective view of a part of the shaft rotation joint provided on the upper surface of the tower, and is a perspective view of a connecting seat and a slide seat (connecting portion) 300 for slidably attaching the connecting portion and the panel. It is the perspective view which looked at the top.

In this embodiment, a solar panel rotating body 100 including a solar cell panel 10S as a solar panel and a pedestal frame 11 on which the panel 10S is fixedly mounted, and a base surface (installation surface) on the ground or a rooftop. A tower 20 having a predetermined height fixedly disposed, and a sun tracking drive unit (MDU and electronic control unit) that rotationally drives the panel rotating body 100 are provided. The panel rotating body 100 includes one side 1a provided with a rotating wheel 16 and the other side 1b facing the rotary shaft portion 30aa. The panel rotating body 100 is provided with the rotating shaft portion 30aa other than the center of the rotating body and other than the center of gravity. The one 1a is installed on the horizontal installation surface 91 via the wheel 16 and the leg body 122, and the other 1b is connected to the shaft tower via the shaft rotation joint portion including the rotation shaft portion 30aa and the connection portion 300. 20 supports a part of the panel rotating body load (bearing one part of the three-point support). The rotating wheel 16 is fixedly attached to the panel rotating body 100 corresponding to both sides of the one 1a (FIG. 9 shows only one of them). The sun tracking drive unit MDU2 faces, for example, the rotating wheel 16 so as to drive the rotating wheel attached to the leg 122 fixed to the pedestal frame 11, for example, facing at least one side of the both sides. It couple | bonds and it is provided in the leg body 122. FIG. Thus, in this embodiment, when the wheel 16 is rotated by the sun tracking drive unit MDU2, the wheel 16 is installed while the panel rotating body 100 is supported by the shaft tower 20 via the joint portion JT. By rotating the surface, the panel rotator 100 rotates and azimuthally shifts around the joint shaft part to track the sun.

The installation surface 91 on which the rotating body 100 rotates via the wheel 16 may be a building, a rooftop of a house, or a concrete surface on the ground itself. In this embodiment, the upper surface of a special rail member RR is used as the installation surface 91. It is said. As the special rail member, for example, FIG. 3 (rails 18, 28, 38, 48) of Japanese Patent Laid-Open No. 2005-273201 invented by the same inventor can be used as it is. The panel 10S is fixedly mounted on the pedestal frame 11, and includes a wheel 16 rotatably attached to a lower end portion of a leg body 122 projecting downward from a lower surface of the lower lower end portion of the frame 11. 16, the lower part of the rotating body 100 is rotatably supported. The upper portion rotatably supports the shaft portion 30aa of the joint portion so that the azimuth angle shifts and rotates about the shaft portion 30aa. The shaft portion 30aa is provided in the shaft tower 20 that can be supported to be extendable in the vertical direction. The tower 20 is made of pyramid type stems -260 and 270 which are erected obliquely from a predetermined four locations inside the rail portion of the rail member RR formed in a substantially donut shape having a flat upper surface toward a central point. The middle part CU of the tower 20 is supported. The tower 20 is composed of a rectangular parallelepiped lower section 210 connected and fixed to the rail member RR, and a rectangular parallelepiped upper section 220 that can slide up and down to be held at a predetermined position. As shown in the horizontal section of FIG. 11, the lower part 210 is formed slightly smaller than the upper part 220.

In order to prevent the shaft tower from collapsing, the upper ends of the stays 260, 270 are to be attached to the upper portion of the shaft tower 20 as much as possible. However, since the elevation angle of the panel 10S is assumed to be changed, It was made to stick. The intermediate part CU is at the upper end of the lower part 210, and a through hole 210C is provided on the upper surface 210a of the lower part 210 so as to penetrate the rotary shaft part 30aa while having a clearance. Four elongated holes 210e and 210f (the other two are not shown) facing in four directions are provided immediately below the intermediate portion CU. The elongated holes are formed in the upper portion 220 so that the cross-shaped shaft holding member 240 can slide up and down. Open to hold. The shaft tower upper part 220 includes a shaft hole 20a provided on the upper surface 220a and a shaft holding part 246 of the central part 241 of the shaft holding member 240 provided on the lower surface, and the rotary shaft part 30aa is connected to the shaft hole 20a and the shaft holding part. H.246 and 246 can hold the azimuth angle freely. The shaft tower upper part 220 has long holes 220e, 220f in its side walls 220i, 220j, 220k, 220l in order to make the stays 260, 270 and the radial legs 242, 243, 244, 245 of the shaft holding member 240 approach and separate. 220g and 220h.

The shaft holding member 240 is screwed to the polygonal ring-shaped mounting member 230 with screws 232 to 235 via the legs 242 to 245 for holding the shaft holding member 240 to the upper part 220, and this frame-shaped cross member is attached to the upper part 220. The shaft tower upper part 220 is assembled by fitting into the lower end of the shaft from below and screwing with screws 236, 237, 238, 239. Here, the assembly procedure of the tower 20 is organized and shown.
1) The shaft tower lower part 210 is suspended and fixed to the rail member RR by the steps -260 and 270.
2) Insert the shaft tower upper part 220 from the upper part of the shaft tower lower part 210 as shown by arrow Y91 in a state where the cross member with frame (230 + 240) is not attached. Since this action is performed before the rail member RR is attached, it may be laid down and inserted.
3) The attachment member 230 is inserted into the lower end of the upper part of the tower from the lower part of the lower part of the shaft tower 210, and its four corners are fixed with screws 236 and 239 as shown in FIGS.
4) The shaft holding member 240 is inserted into the shaft tower through the long holes 220e to 220h and 210e, 210f (possible from any of four locations), and in the state shown in FIG. 10B, the shaft tower is set with screws 232, 233, and 234. Screwed to the mounting member 230 via the lower part 210. At this time, the inner end surfaces of the long holes 210e to 210h and the long holes 220e to 220h and the opposing surfaces of the radial legs 242 to 245 are fitted with a clearance (see FIG. 11).
5) With the tower tower upper part 2220 and the tower tower lower part 210 joined and integrated, the tower tower lower part 210 is suspended and fixed to the rail member RR by the steps -260,270.

In addition, cu1 is a screw hole opened in the intermediate part CU, and the upper part of the stage and the upper part of the tower tower lower part 210 are fixed to each other by a screw (not shown) via the upper end part screw hole. Reference numeral 270a denotes a screw hole formed in the upper end portion of the stay 270 for fixing to the vertical surface 210k perpendicular to the holding surface of the screw hole cu1. The shaft portion 30aa has a structure like a long nail as a whole, and the portion that contacts the nail head is a rotation holding portion 3T that receives and supports the load of the rotating body 100 including the panel, and is made of metal. The shaft body (the part excluding the holding portion 3T) and the holding portion 3T are welded at the connecting portion. The shaft portion 30aa is inserted from the shaft hole 20a of the shaft tower upper upper surface 220a, the lower end portion of the shaft portion 30aa is inserted into the shaft holding portion 246, and the shaft portion 30aa is attached to the shaft tower 20 so that the azimuth angle can be changed. .

As employed in the first embodiment, the direct rotation holding portion between the shaft hole 20a and the shaft holding portion 246 is a portion that rotates while applying a large force in the horizontal and vertical directions. It is desirable to adopt a structure consisting of In such a case, the shaft holding portion 246 has a stepped portion lowered by one step, and a bearing bearing with a downward movement prohibiting stopper function is disposed on the stepped portion. Then, the lower end portion of the shaft portion 30aa is also provided with a stepped portion having a reduced diameter so as to be fitted thereto so as to be freely rotatable. It is preferable that most of the vertical load is received by the above-described bearings with the two stepped portions to be fitted. In order to prevent the shaft from dropping off from the bearing in the event of an abnormality such as an earthquake, an E-ring stopper member is interposed at a portion where the lower end portion of the shaft portion 30aa penetrates the shaft holding portion 246. Also good. Then, the shaft portion 30aa does not come off the bearing. The above-described shaft tower is shown as an example in which the shaft tower is fixed to a predetermined vertical length. Therefore, a screw (bolt for fixing the vertical positions of the upper and lower parts 220 and 210 at a specific position of the upper part 220 at a position where the overlap portion between the upper part 220 and the lower part 210 is the smallest, that is, a position where the tower is set highest. ) 250, 251, 252, and 253 are provided as shown in FIGS. 9 and 11, and screws 236 and 237 are provided at a plurality of corners of the mounting member 230. Depending on the season, the vertical length of the tower is set, and the upper and lower portions 220 and 210 are fixed with fixing screws 250 to 253.

A connecting portion made of a hinge member 3abc for connecting the rotating body 100 and the tower 20 in a predetermined relationship is placed on the upper surface of the rotation holding portion 3T. The hinge member 3abc has substantially the same configuration as that of the first embodiment, but is functionally different from that of the coil spring 3SP, which is rotatably attached to the shaft portion 3cc and biased in the normally open direction (opening direction from FIG. 12). It is a point that is added. In this embodiment, a hat-shaped slide seat 300 having a cross section in the short direction fixed to the lower surface of the other 1b of the rotating body 100 (the upper lower surface of the pedestal frame 11) with mounting screws 301 and 302 is further provided. One of the hinge members 3aa is fixed to the flat top portion 350 of the slide seat 300 with screws 304 and 305, and the other 3bb is brought into contact with the holding portion 3T so that screw holes 306, 307, 308 of screws (not shown) are provided. The rotating body 100 and the shaft tower 20 are rotatably attached by insertion into 309 and screw insertion into the holding portion 3T. Furthermore, the slide seat 300 is provided with a top portion 350 via rising portions 330 and 340, and a space SS is provided. In a state where one head portion of the slide coupling portion CN loosely fitted in the space SS is projected from the long hole 360 provided in the longitudinal direction of the top portion 350 into the space SS, the slide coupling portion CN Is loosely fitted to the hinge member and the slide seat 300.

In this embodiment, the connecting portion 3abc and the slide seat 300 can be temporarily locked in a loosely fitted state at the slide coupling portion CN. The reason for this is that triangular projections 353 and 354 are provided on both sides of the long hole 360 of the top portion 350 at several locations in the longitudinal direction, and the hinge member Ta is in contact with the triangular projection to set the elevation angle of the rotating body 100. . At this time, the rotating body 100 and the tower 20 are fitted loosely without being completely separated from each other, over the triangular protrusions (or quadrangular protrusions) 353 and 354, and the triangular protrusions at different positions (for example, 351, This is because one side 3aa of the connecting portion 3abc is desired to be moved to 352), and it is difficult to change the elevation angle of the panel without the loose fitting state. As described above, when the panel elevation angle is moved, the elevation angle setting confirmation of the panel 10S is performed while the temporary engagement is performed using the triangular protrusion.

If the angle needs to be further changed, the above operation is repeated, and after the target elevation angle is changed, the fixing to the slide seat 300 is continued with the screws 304, 305 and the like. In the elevation angle changing operation of the panel 10S, the connection between the other 3bb and the holding portion 3T may be left as it is. When changing the elevation angle of the panel 10S, if the shaft 250 is loosened to make the tower 20 extendable and the screws 304 are loosened to bring the panel 10S and the tower 20 into the temporarily locked state, the panel 10S. Since the lower end portion is freely rotatable by the wheel 16, the panel, the tower, and the installation surface constituting the link mechanism are temporarily extremely unstable and temporarily present a dangerous state. Therefore, the link mechanism may be temporarily locked by the stopper member STT so that the metastable state is achieved even in the temporarily locked state. For example, as shown in FIG. 13, the wheel stopper member SST made by matching the holding width W1 with the road width of the rail member is illustrated. The stopper member SST is provided with recesses S1 and S2 into which the wheel 16 is fitted on the upper surface SU of the base portion SB whose vertical section perpendicular to the wheel traveling direction is a reverse cup shape. The recess S1 is formed by notching the upper surface SU to be equal to or slightly larger than the wheel 16, forming a recess S2 having steps S3 and S4 of the same width as the wheel 16, and curved upward in the order of S3 and S4. A recess is formed so as to rise. The step surface S4 having a curved surface is configured in accordance with, for example, the outer peripheral curved surface of the wheel. It is desirable that the wall surface S5 of the recess S2 is formed with the same width as or slightly larger than the wheel 16, and the end surface S6 of the upper end portion of the wall surface S5 is not higher than the rotation axis of the wheel.

Such a stopper member SST is inserted so as to press the concave portion on the wheel so as to be opposite to each other with respect to the two wheels on both sides of the panel from the traveling direction of the wheel or the opposite direction, and the traveling direction of the wheel. Further, wheel movement (panel movement) in the direction perpendicular to the traveling direction is prevented. If the metastable state is established after the panel movement is temporarily locked by the stopper member in this way, the panel change setting operation becomes extremely easy to work. When one of the connecting portions 3abc is in contact with the triangular projection, the sliding movement after the projection has been overcome when changing from one projection having the triangular projection to another projection, Thereafter, the spring 3SP works so as to always push up 3aa by the action of the spring 3SP, so that it can be moved to the next metastable state simply by holding the upper end of the panel and moving it up and down. By repeating this operation, it is possible to easily perform an arbitrary elevation angle change setting operation.

As described above, the first and second embodiments have been described. The mounting position of the shaft rotary joint portion (rotary shaft portion) with respect to the entire solar panel rotating body is the other of the solar panel rotating body (an upper portion disposed obliquely). You may provide in the horizontal direction center part. If it does so, the whole movement area may be small. Further, the load applied to the joint part may be supported by the shaft tower so that the load applied to the joint part exceeds zero and is ¾ or less of the total weight of the solar panel rotating body. If it does so, both a movement assistance member (wheel) and a shaft rotation joint part (rotation shaft part) will not be burdened, stability will increase and durability will also increase. Further, since the joint portion has the horizontal movement blocking portion (27w) for blocking the horizontal position movement of the panel, the joint portion is unlikely to be disengaged even when a disaster is abnormal. Moreover, a clearance mechanism is provided that can tilt when the joint portion is within this range by providing a stopper mechanism that does not tilt further when the shaft tilts (for example, 3 degrees) of the joint portion (FIG. 16b). As a result, the panel can be moved even if the ground contact surface is slightly uneven. It is possible to slightly widen the allowable range of the axis collapse phenomenon described later.

<Third Embodiment>
Next, a third embodiment will be described with reference to FIGS. FIG. 14 is a perspective view of a solar tracking solar energy receiver device. The solar energy receiver of the device is depicted as being primarily a solar water collector heat collection panel 110. FIG. 15 is a side view of the main part (FIG. 15A) and a diagram (FIG. 15B) for explaining the operation. FIG. 15 (A) shows the change mode when the panel angle is changed by comparing the solid line and the dotted line. . FIG. 16 is a perspective view mainly showing the shaft rotation joint portion of the panel rotation shaft support structure. FIG. 17 is a view showing a lock mechanism having both a panel angle holding function and a panel lock function. First, FIG. 14 will be described.

A feature of this embodiment is that the shaft tower according to claims 1, 3, 4 and the like is fixed to a base surface (installation surface such as a roof of a house, a roof of a building, or a ground surface) with respect to the entire apparatus. The tower is part of the building. Moreover, the part is said to be provided using necessary parts of the building. For example, if there is a building having a rooftop veranda, this building has a rooftop entrance for entering and exiting the rooftop. There must be a staircase at this doorway. Since this staircase is formed obliquely, the entrance / exit part is often formed obliquely. This part is slightly deformed to form a hemisphere. For example, in this embodiment, this portion is used as a part of a shaft tower (stepped portion covering structure of a rooftop entrance). A part of the tower is a part that forms the foundation of the tower, and a shaft tower body part for supporting the panel is necessary on the part. In this sense, the expression “part of the tower” is used. .

The tower base 8 is a building composed of a partial sphere smaller than the hemisphere (hereinafter referred to as a hemisphere). If the shaft tower main body for supporting the panel can be integrally formed in this hemisphere, the shaft tower base 8 functions as the shaft tower of claim 1 as it is. Assuming that the tower main body is a separate body, the tower base 8 is configured as, for example, a stepped covering structure for a rooftop entrance. The top surface 85 is supported by a plurality of longitudinally curved frames 81, 81,... Constituting the hemisphere. The lower end of the frame 81 is connected to the horizontal curved frame 82 that connects the plurality of frames 81 together and has an integral structure. A hemispherical frame composed of these frames 81 and 82 and the top surface 85 is connected and disposed by translucent plates 83 and 83. The through-hole plate 83 is made of, for example, a transparent or translucent acrylic panel, a tempered glass plate, or a reinforced resin plate. The portion of the through-hole plate 83 may be formed of an opaque simple wall material.

Around the lower periphery of the hemispherical tower base 8 is provided a C-shaped wheel rail 90 when the panel 110 rotates. The rail portion 90 has a substantially T-shaped or rectangular shape in cross section, and includes an upper wheel rolling surface 92 (also an installation surface or a base surface) and both side surfaces 93 and 94. A partial circumferential connecting portion 95 between the lower peripheral portion (frame 82) of the tower base 8 and the rail portion 90 is formed one step lower than the upper surface 92 as shown in FIG. A base portion 6Z of a column 6Y (FIGS. 15 and 16) that supports the hot water storage tank 50 is fixed to the top surface 85 by screws or the like (not shown). A support column 6 </ b> Y welded to the base portion is erected, and the upper end portion of the support column 6 </ b> Y is abutted and fixed to the lower surface of the tank 50. A shaft rotation joint portion JT including a panel rotation shaft 3Y is attached to the side surface of the column 6Y, and the panel 110 is placed on the rolling surface 92 of the rail portion 90 on the rolling surface 92 around the rotation shaft 3Y of the joint portion JT. Move through. The non-flexible pipe part PS having the same function as the previous embodiment is attached to the upper end surface of the panel as in FIG. 3, and the other is connected to the flexible pipe part FP. The pipe FP is always connected to the tank through the curved part FP1. 50. The joint portion JT is disposed under the pipe portions PS and FP.

The lower surface of one side 52 of the tank 50 is supported by the support column 6Y, and the other side is supported in a form fitted into the upper central recess 807 of the building 80 as the rooftop entrance. The building 80 is formed as a hexahedron, for example, a hexahedron, and includes a south surface 801, a north surface 802, an east surface 803, a west surface 804, an upper surface 805, and a lower surface. The shaft tower base 8 is provided in the form of projecting in the south direction at the center of the south surface 801. The north side of the tower base 8 and the central part of the building 80 form a connecting portion that communicates internally, and a stair that goes up to the roof is provided inside the tower base 8 as shown in STEP of FIG. A landing 97 that climbs up the stairs is formed inside the building 80. The north surface 802 is provided with a door (entrance / exit part) 808 for entering and exiting the roof. An auxiliary tank ST is provided inside the building 80 as necessary.

The panel 110 of this embodiment may be a larger panel than the first embodiment. The larger the size, the larger the devices and parts for controlling the panel elevation angle, and the more difficult it will be to realize durability and other aspects. You can also In this embodiment, the solar tracking system with only the azimuth movement control without the elevation angle control can be implemented. It was constructed as a hardened system (mechanism).

15 to 17 show a configuration in which the safety in the emergency is improved. FIG. 15A can be said to be a side view of FIG. As described above, the support column 6Y is erected on the top surface 85 via the base 6Z, and supports one side of the tank 50 (south surface on the south side at the upper end). Since the load of the panel 110 is also shared and applied to the support column 6Y, it can be said that the support column 6Y corresponds to the shaft tower main body when corresponding to the first embodiment. The column 6Y has a T-shaped horizontal section made up of ribs 6Y1, 6Y2, and 6Y3, as is apparent from FIG. However, the column 6Y may have a U-shaped horizontal section. And the joint part JT is attached to the up-down direction intermediate part of this T-shaped support | pillar 6Y. FIG. 16 is a perspective view showing details of the joint portion JT. In the intermediate portion, a substantially bowl-shaped bearing portion 6Y6 (shaft bearing portion) based on a plate-like mounting seat 6Y5 is provided on the outer surface of the ribs 6Y2 and 6Y3, and the shaft portion 3X is rotatable on the shaft portion. The joint portion JT is pivotally supported via the fitted shaft hole (hole-shaped shaft portion 3X). The two lower protrusions 3d8 provided with the shaft holes are provided so as to protrude from the lower surface of the vertical F-shaped holding member 3d that is F-shaped in a side view. A shaft hole 3h is provided in two horizontal pieces 3d6 and 3d7 which protrude horizontally from the vertical wall piece 3d1 of the member 3d and are vertically separated. The shaft hole 3h is a shaft hole for fitting the panel rotation shaft (vertical axis) 3Y. The shaft 3Y passes through a vertical wall 3b5 in the wing portion 3b1 of the hinge member 333 including one wing portion 3a1, the other wing portion 3b1 having an inverted U-shape in side view, and a shaft portion 3c1 that rotatably couples the wing portions. It is a shaft portion fixed to two horizontal pieces 3b2, 3b4 which are vertically separated.

With this structure, when the panel 110 is used, the other wing 3b1 can be rotated while being kept horizontal. In order to keep the wing 3b1 horizontal while supporting the panel diagonally, a reinforcing piece 3b6 is provided continuously to the horizontal piece 3b2 and the vertical wall 3b5. That is, the shaft 3Y rotates. This may be structured such that the shaft 3Y does not rotate but the 3b2, 3b4 rotate. In the former structure, it is desirable that the shaft rotating portion has a structure in which a round bar shaft is fitted via a ring-shaped bearing bearing portion fitted in the shaft hole 3h. The upper portion of the vertical axis holding portion 3d is divided into two pieces, one piece 3d2 and the other piece 3d3, and a U-shaped groove 3d5 is provided therebetween. Corresponding to this U-shaped groove 3d5, a long hole (through hole) 6Y8 is provided on the side of the rib 6Y2 in the portion of the column 6Y. The U-shaped groove 3d5 and the long hole 6Y8 are provided so that the communication pipes FP and FP1 that connect the tank 50 and the panel 110 communicate with each other. The fixed pipe PS (functionally identical to FIG. 3) projecting from the upper end surface of the panel 110 is horizontally arranged (the flowing water direction is horizontal) when the connection end TT1 with the flexible pipe FP is normally used (solid line in FIG. 15). And the flexible pipe FP is horizontally connected. Further, it is assumed that the U-shaped groove 3d5 and the long hole 6Y8 are horizontally arranged in a state where the flexible pipe FP is in contact with the U-shaped groove 3d5, and the subsequent portion FP1 is bent into a U shape and connected to the tank 50.

Further, a protrusion 3d9 is provided on the joint portion JT. The protrusion 3d9 protrudes toward the column 6Y (north direction) below the U-shaped groove 3d5 and above the horizontal piece 3d6 in the vertical axis holding member 3d1. As shown by the solid line in FIG. 15, the protrusion 3d9 is provided through the through hole h1 opened in the rib 6Y2 in a state where the support 6Y and the member 3d1 are in contact with each other, and the through hole h1 is provided in the protrusion 3d9. It is provided in a slightly larger size. As shown in FIG. 17, a rod driving piece K1 that is locked in a state where the projection 3d9 penetrates the hole h1 is provided so as to be movable with respect to the column 6Y in a lock style. The driving piece K1 is held by a holder K so as to be able to move horizontally on the ribs 6Y2 and 6Y3, and the holder K is fixed to the rib 6Y3 by screwing its seat KB with screws SC6 and SC6. . The holder K is configured in a horseshoe shape, and a drive piece K1 is inserted through the center. One end of the drive piece K1 is configured to pass through the through hole h5 opened in the rib 6Y1 and further pass through the hole h2 of the protrusion 3d9 through the through hole h5. An interlocking protrusion ac is provided on the upper surface of the horseshoe portion of the holder K. A lever LB having a long hole h3 that fits into the protrusion ac is rotatably mounted via a mounting seat 6Y4 of the rib 6Y3. The lever LB is held so that the free end side intermediate portion straddling the protrusion ac is not separated from the rib 6Y3 at the time of movement and stop by the U-shaped guide portion GD that guides the movement of the lever LB. Further, a tension spring S6 for biasing the lever LB in the direction of the rib 6Y1 is provided on the free end side of the guide portion GD so that both ends of the lever LB and the rib 6Y1 are locked. A stopper portion ST6 is provided between the spring S6 and the guide portion GD so as to be in contact with and fixed to the ribs 6Y1 and 6Y3, and the lever LB is urged by the spring S6 so as to contact the stopper portion ST6. Since the overall length of the lever LB is several times longer than the length of the mounting seat 6Y4 and the protrusion ac, the drive piece can be easily moved even when a large force is required for the horizontal movement of the drive piece K1. K1 can be moved horizontally.

During normal use, this solar energy receiver device is used with the joint portion JT in close contact with the support 6Y as shown by the solid line in FIG. The horizontal piece 3b2 (the other wing portion 3b1) is kept horizontal, the shaft 3c1 is kept horizontal, and the flexible pipe portion FP (other than the curved portion) is kept horizontal. At this time, the upper portion of the panel 110 is lifted upward to the position indicated by the solid line, while the lower portion is placed on the wheel rolling surface 92 of the rail portion 90 via the legs 12 and the wheels 16. When the wheel 16 is driven by a motor drive unit (not shown) attached to the leg 12, the wheel rolls on the surface 92.

When an alarm is issued in preparation for a typhoon or earthquake, if the spring S6 is slid in the extending direction while holding the upper end of the lever LB, the force is transmitted in the order of the long hole h3, the protrusion ac, and the driving piece K1. The one end of the drive piece can be detached from the holes h5 and h2. Then, the projection 3d9 is in a state where it can be detached from the hole h1. At this time, since the panel load partial pressure in the vertical direction is hung on the shaft end 3c1 of the wing portion 3b1, the shaft end 3c1 (hinge shaft) of the wing portion 3b1 away from the shaft 3X is rotated in the clockwise direction ( The force of FIG. 15a is generated. With this force, each part moves to the position shown by the dotted line. To what extent the transition is made, the lower end horizontal projection STP of the stopper member ST8 provided below the panel 110 enters the undercut portion 901 so that it faces the inner side surface 94 of the saddle rail 90, and the undercut portion 901 The transition state of the panel 110 is regulated by the contact portion P8 immediately above the protrusion STP being in contact with the side end portion of the panel 110. The contact portion P8 may be covered with a cushioning material P88 made of a leaf spring or a copper material. The buffer material P88 may be further provided continuously or separately on the upper surface of the protrusion STP. Then, during the operation before the lever LB, a transition is made from the solid line state during normal use to the panel 110 holding state (panel holding strengthening state) in the abnormal standby state. In the panel holding strengthening state, the position of the wheel 16 stops at the position illustrated by the dotted line near the outer end of the rail portion 90.

The transition from the normal use state to the abnormal standby state can be performed instantly by one-touch horizontal movement of the lever LB. In the abnormal standby state, self-gravity acts on the panel 110 itself so that the shaft 3c1 tries to move on the circumference having the radius of 3X-3C1 as a radius, and the contact force is exerted on the undercut side end surface and the contact portion P8. (Pressing force) always works. This force (the force of the gravity wedge presses the end face on the undercut side) causes a frictional force to act on the contact portion, so that it is difficult to move in the universal direction (all directions).

The panel lock mechanism acting as described above can be described from the viewpoint of “action by gravity wedge”. The action will be described with reference to FIG. 15B, but before that, what is a “wedge” is defined. A wedge is a tool that has been used since BC, and it is a “triangular object splitting tool with a thin tip, and when the tip is brought into contact with the split surface of the object vertically, the force F When the abutment surface is pushed, the component force x is generated in the splitting direction and the object is split by the component force. Then, the force F is applied to another object instead of the mass of the wedge itself (self-gravity), and a gravity wedge is defined. The gravity wedge holding structure means that “the direction of the force that the wedge object holding portion adjacent to the wedge object applies to the holding portion contact portion of the wedge object in a state where gravity G is applied downward to the wedge object. A holding structure in which the holding force Z ′ generated upward and inward of the wedge object is balanced by a pressing force that has the same scalar amount as the holding force Z ′ but in the opposite direction (required stone holding structure) " FIG. 15B is a diagram showing a wedge being pierced by a split object and the object being split to the left and right.

It is assumed that the wedge of the triangle ABC with the apex angle a having A as the vertex is inserted with the force F perpendicular to the split surface SUK of the object. At this time, it is assumed that all the acting forces work for the intermediate point p of the wedge blade for the sake of convenience, and the analysis proceeds. When the mass (gravity acceleration) of the wedge object is G, the force F is equivalent to the force G. This force G is shared by two points p, p on the left and right, and is balanced as shown in the figure by receiving a reaction force from the object by (1/2) G. Consider the p point on the left. At the point p, a force of G / 2 is applied downward to the object below the wedge by gravity. The force G / 2 can be expressed by a component force z perpendicular to the wedge blade side surface and a component force e parallel to the wedge blade surface. z, z′G, and x are vectors. And, when the relational expression between the horizontal component vector x of z and the wedge gravity G is expressed by trigonometric function theory,

x = (G / 2) * [cos {90- (a / 2)}] * [sin {90- (a / 2)]

It becomes. * Represents a product. As can be seen from this equation, when the scalar product (ze area) of z and e is the maximum, x takes the maximum value. That is, the maximum value is when a = 90 degrees or (a / 2) = 45 degrees. At this time, x is x = (G / 4).

When this idea is introduced in FIG. 15A and reconsidered, the force (moment) generated around the axis of the axis 3c1 is split by the solar panel rotating body including the panel 110 with respect to the split object including 3b1. It can be said that a certain wedge object is equivalent to a splitting force (moment). Accordingly, g acting on the shaft 3c1 in the downward direction is g = (G / 2), and if the total weight is, for example, 100 kg, the maximum value of x is 25 kg. For example, if the line segment 3c1-3x when the panel is normally set is 45 degrees with respect to the vertical line and becomes 60 degrees when the panel is locked, x is 25 kg to 21.7 kg. This horizontal splitting force x acts as a force by which the stopper STP pushes the side surface 94 or P8 pushes 901. That is, when the driving piece K1 is detached from the hole h2 of the protrusion 3d9, the initial detachment force by which the protrusion 3d9 is detached from the column 6Y has the same rotational moment if the line segment 3C1-3X and the line segment K1-3X are equal. Then it is 25kg. Thus, it can be said that the detaching force (panel lock initial driving force) has an instantaneous force and also has a holding force (21.7 kg in the above example) when the panel is locked. Further, the effect of the keystone, that is, the effect of wedge tightening that makes the panel holding part relative to the fixed part even if a clearance occurs due to the shaking of the panel at the time of abnormality (the effect that the wedge gets deeper as it moves) Equivalent).

Furthermore, even if the panel is forced to move up due to a typhoon or earthquake, the upper surface of the protrusion STP abuts the lower surface of the undercut portion, so that the panel cannot be moved upward. . As a further safety measure, a panel movement prevention measure can be applied in a nearly complete form by simply placing a wedge member (not shown) in a V-shaped valley formed between the back surface of 3d1 and the rib 6Y3.
As a return plan after the abnormal situation has passed, the following measures are taken. The panel 110 can be returned from the dotted line state to the solid line state by pushing up and pressing the front bent piece 3d4 provided on the upper part of the other piece 3d3 of the vertical axis holding member 3d backward (rightward in FIG. 15).

<Fourth Embodiment>
Next, a fourth embodiment will be described with reference to FIG. FIG. 18 is a side view of a main part of the solar tracking type solar energy receiver device partially shown in cross section. The drawing scale is changed between the upper part (right figure) and the lower part (left figure), and the joint portion JT is drawn several times larger than the periphery of the wheel. The solar energy receiver of the device may be a solar cell (photovoltaic power generation) panel 10S or a water heater heat collector 10. In the case of a heat collector, it is desirable to bundle a large number of cylindrical heat collectors that do not require a separate tank. The inlet / outlet pipes are connected in parallel to the upper end of each cylindrical heat collector, integrated into the vicinity of the heat collector as shown in Fig. 4, and suspended along the shaft tower with a plexiplex pipe from a single place. Then, it is only necessary to connect to the use device.
The feature of this embodiment is that the solar panel rotating body 100 including the solar panel 1 and the pedestal frame 11 on which the panel 1 is fixedly mounted, and the base surface 9 on the ground or the roof are fixedly disposed. A tower 20 having a predetermined height and a sun tracking drive unit (MDU and electronic control unit not shown in the figure) for driving the panel rotating body 100 to rotate. The drive unit is provided in the same manner as in the second embodiment (FIG. 9 and the like). The panel rotating body 100 includes one side 1a and 10Sa provided with a rotating wheel 16 and the other side 1b and 10Sb facing the rotary shaft portion (25Q or 27Q). The panel rotating body 100 is provided with the rotating shaft portion (25Q or 27Q) other than the center of the rotating body and other than the center of gravity. The one side 1a and 10Sa are installed on the horizontal installation surface 92 via the wheel 16 and the leg body 122, and the other side 1b and 10Sb are the rotating shaft portion (25Q or 27Q) and the connecting portion (slide seat). A part of the panel rotating body load (a part of the three-point support is borne) is supported by the tower 20 through the shaft rotary joint portion JT including 300. The rotating wheel 16 is fixedly attached to the panel rotating body 100 corresponding to both sides of the one side 1a and 10Sa (FIG. 18 shows only one side). In this embodiment, when the wheel 16 is rotated by the drive unit, the wheel 16 rotates the installation surface 92 while the panel rotating body 100 is supported by the axle tower 20 via the joint portion JT. Thus, the panel rotating body 100 is characterized in that the azimuth angle shifts and pivots around the joint shaft portion 25Q to track the sun.

Further, this embodiment is characterized by the structure of the joint portion JT. That is, the shaft rotation joint portion JT is a universal joint mechanism. In FIG. 18, a solid line diagram shows an example of a solar battery panel, and a one-dot chain line diagram shows an example of a water heater. The joint portion JT and its mounting structure will be described below using a solid line diagram. The shaft tower 20 may have a vertically movable shaft tower structure as in the first embodiment or the second embodiment, or may be a shaft tower having a predetermined height that does not move up and down. For example, if the shaft tower structure of the first embodiment is used, in FIGS. 1 and 3, bearing portions BJ1 and BJ2 provided on the horizontal upper end portion 22a and the horizontal lower end portion 22b of the triangular plate welded to the main body portion 22 such as the shaft, respectively. Without the shaft hole, the shaft portion 30a is removed, and the mounting seat 25a of the vertical cross-section inverted T-shaped shaft seat 25 having a bearing function is attached to the horizontal end portion 22a of the triangle plate with a screw 25n. , 25n. The tower top surface portion 201 corresponds to the triangular plate end portion 22a not having the bearing portion BJ1. The vertical portion 25b of the shaft seat 25 has a cylindrical shape, and the upper end of the vertical portion 25b is formed as a spherical bearing portion 25Q. The shaft seat 25 is formed by integrally cutting a metal such as iron, stainless steel, brass or the like including the mounting seat 25a, the bearing portion 25Q, and the over-rotation preventing stopper body 25S. The stopper body 25S has a short skirt shape if it is a cut-out integrated type, and is constituted by a surrounding four-point stop block body that is screwed with a screw (not shown). Screw holes and the like are formed by drilling work after cutting.

The other upper end 1b of the panel rotating body 100 fixes the panel 1 via a shaft body 27 having a concave spherical portion 27Q fitted to the spherical bearing portion 25Q and a slide seat 300 (see FIGS. 9 and 12). It is formed to be rotatable in the universal direction by being attached to the upper part of the pedestal frame 11 to be placed. “Rotatable in a universal direction” refers to a rotation that allows a change in any rotational direction of one or a plurality of three axes orthogonal to each other. The “universal rotary joint portion” refers to a joint portion in which the connection portion (panel side) and the connected portion (fixed side including the tower) are rotatable in the universal direction, as indicated by JT.

The upper end portion of the shaft body 27 is slidably attached to the slide seat 300 via the attachment seat 3aaa. The slide seat 3aaa is functionally equivalent to one 3aa (see FIG. 12) of the connecting portion 3abc corresponding to the hinge member 3. The column 27c of the shaft body 27 projecting downward from the mounting seat 3aaa is reinforced by triangular reinforcing portions 27a and 27b welded to the column 27c and the mounting seat 3aaa, and a cylindrical shaft portion is provided below the columnar shaft portion 27c. 27d is provided by cutting. The shaft portion 27d has the semispherical concave sphere portion 27Q below the shaft portion 27d, and is provided with a drop-off preventing side wall portion 27W extending along the outer surface of the cylinder. A stopper 27S is provided on the inner side of the lower end of the wall portion 27W to prevent over-rotation by contacting the spherical bearing portion 25Q when the panel rotating body 100 over-rotates in the elevation direction. A linear groove 25R as shown in the figure may be provided in either the bearing portion 25Q or the spherical portion 27Q, for example, the bearing portion 25Q. This concave groove is used as a lubricant filling portion such as grease so that the sliding operation can be smoothly maintained over a long period of time when the 25Q and 27Q are fitted and slid. In addition, although the diameter of the ball | bowl of the said bearing part 25Q is based also on the magnitude | size of a panel rotary body, 10 mm-100 mm are illustrated. For example, 10 to 40 mm is suitable for the second embodiment (FIG. 9), and 30 to 70 mm is suitable for the third embodiment. About the convex part or recessed part of the said rotating shaft part (25Q or 27Q), you may comprise this reversely, ie, a receiving side (lower side) may be concave, and an insertion shaft side (upper side) may be convex.

Next, the lower end part (one side 1a) of the panel 10S and the peripheral structure of the wheel 16 will be described. A wheel 16 is attached to the lower surface of the lower end portion 1a of the panel 10S via the leg body 122, and a projecting wall W composed of the vertical walls W1, W2, W3 is extended to the lower surface of the leg body 122 and / or the frame 11. Has been established. The upright walls W1 and W2 are formed of two surfaces substantially orthogonal to each other, and the upright wall W2 protrudes horizontally outward from the outer side surface 93 of the wheel rolling surface 92 of the rail portion 90. Is configured to avoid. At the lower end of the upright wall W2, there is provided a projecting piece WS for preventing falling off at the time of projecting toward the center of panel rotation. In addition, the lower end portion (one side 1a) of the heat collector 10 in the one-dot chain line diagram is merely thick (drawn as about twice), and the others are the same as the solid line diagram (however, the elevation angle fixing method is used when used). ). The mounting structure of the upper end (the other 1b) of the heat collector 10 to the joint part JT, if the solar tracking method adopts the azimuth angle shift and elevation angle fixing method, only adopts the solid line structure as it is but the thickness is different. Although there is no problem at all, if the azimuth and elevation shift method is adopted, the universal joint structure is slightly modified to improve durability in pipe connection between the heat collector and the tank. The structure is desirable. An example of the structure is the structure shown in the chain line diagram. Also in this configuration, the shaft structure (25 and 27d) composed of the sphere and the concave spherical surface is basically the same and may be the same. However, the structure of attaching the panel-side shaft body 27 to the panel is slightly different. First, in the solid line solar cell panel 10S, as shown in FIG. 9, the mounting seat 3aa (3aa in FIG. 9) can slide on the lower surface of the panel (the top surface 350 of the slide seat 300). In the heat collector 10 in the chain line diagram, the mounting portions 272 and 273 that are opened at right angles to the lower surface 104 and the upper surface 102 of the uppermost end portion are screwed with screws 276 and 275, respectively. The shaft body 27 which is a supported portion is integrally formed. The boundary portions 273 and 274 between the mounting seats 272 and 273 and the shaft portion 27d are formed by gently transitioning to strengthen the strength.

Since the universal joint mechanism is employed in the fourth embodiment configured as described above, even when the optimum elevation angle varies depending on the latitude or the season, the shaft and the bearing can be easily and easily fitted as in the first embodiment. Can be done. In particular, the operation of attaching the panel 1 with the shaft body to the tower 20 is completed simply by inserting the shaft portion 27d from above to the spherical bearing portion 25Q. At the time of removal, the panel 1 placed obliquely can be removed simply by lifting it upward while maintaining its shape. However, when the panel is attached, the protruding wall W is attached to the panel after attachment, and when the panel is removed, the protruding wall W is removed from the panel 1 before being removed. Alternatively, the projecting piece WS and the undercut portion 902 are prevented from undercutting (can be inserted / removed in a vertical motion) only when the vertical direction (vertical direction in FIG. 18) of the cylindrical shaft portion 27d is vertical, and otherwise The panel angle may be undercut. If comprised in this way, while the protrusion WS is attached to the panel 1, not only can the attachment and detachment of the panel 1 with respect to the tower 20 be performed by one touch, but also the side wall portion in one direction in all directions at the time of abnormality. The panel 1 is not detached from the fixing portions (20 and 90) except when the lifting operation of 27 W or more is performed. In this way, a panel rotation holding structure having a simple configuration and extremely high safety can be realized.

The probability of occurrence of the above-mentioned “moving in one direction and a predetermined length in one direction” is extremely low in a natural phenomenon, and it is clear that it is equal to nothing than looking at fire. In other words, it is not an exaggeration to say that it is possible only at the time of artificial attachment and removal. By configuring in this way, even if the panel is lifted in the event of an abnormality such as an earthquake or a typhoon, the panel is not detached from the fixed portion and does not damage the adjacent building. In this embodiment, since the universal joint mechanism is adopted, it is not necessary to provide a very flat rolling surface 92 such as the rail portion 90. For example, it can be installed on the concrete surface or the ground surface of the roof of a building. Or as a portable solar energy beneficiary device, a shaft tower, a panel with a joint part JT (or a separate joint part) and a drive part are separated, and base camps when climbing mountains, Antarctic bases, grasslands, etc. It is a convenient form to take as a personal belonging to a research team such as an academic survey and use it as a power source for several days to several months. In such a case, the wheel 16 is a slightly larger rubber tire, and the azimuth angle can be changed even on a slightly uneven surface or on a gentle slope. In the above temporary use example, the azimuth angle change and elevation angle fixing method is sufficient, and even if the elevation angle variation mechanism is employed, the method of fixing the tower length after the elevation angle change of the second embodiment method is sufficient. .

When the joint mechanism of the one-dot chain diagram is adopted and the azimuth angle change and elevation angle change method is adopted, the panel rotation radius R (FIG. 6) shown in the first embodiment also varies depending on the elevation angle change. In addition to the structure, it is desirable to add a “elevation angle shift interlocking wheel direction changing mechanism” similar to the first embodiment. The condition is that the upper end portion of the interlocking rod YB is rotatably fixed to the interlocking rod bearing member RC1 projecting substantially horizontally from the fixed portion, for example, the shaft seat 25, below the center of the bearing portion 25Q. By providing the slide holding members RC <b> 2 to RC <b> 5 on the back surface of the panel, the “elevation angle shift interlocking wheel direction changing mechanism” can be added. The difference from the first embodiment can be constructed in substantially the same manner except that the bifurcated leg portion of the interlocking rod YB is slightly left-right asymmetric. Alternatively, the interlocking rod YB leg portion may be left symmetrical by making the mounting positions of the grounding wheels slightly asymmetric. Further, the “elevation angle shift interlocking wheel direction changing mechanism” may use a servo mechanism to change and control the direction of the wheel 16 by a geared motor based on the elevation angle shift signal as in the first embodiment.

As in the second embodiment, even if the elevation angle is changed, the panel rotation radius R can be prevented from changing. In that case, the attachment seat 3aa may be slid with respect to the slide seat 300 as the panel elevation angle changes. In that case, if the stopper member ST8 shown in FIG. 15 (a) is additionally provided and provided so as to hang from the lower surface of the panel on the inner side of the rotation radius, the panel elevation angle transition is performed without using the stopper member SST of FIG. Even if it does, panel setting can be carried out in the position which fastened the wheel 16 to the rolling surface 92 of the rail part 90. FIG. That is, during the panel up-and-down operation, the rail portion 90 is held between the protruding wall W and the stopper member ST8, so that the lower portion of the panel can be held while providing clearance, so the screws 305 and 304 are removed, By simply moving the panel up and down, the desired angle can be obtained. Then, the elevation angle of the panel may be set so that the contact portion between the wheel 16 and the rolling surface 92 is at an intermediate position between the protruding wall W and the stopper member ST8 by fine adjustment. If a wedge member that fills the clearance between W2 and 902, 901 and ST8 is inserted only in this operation and the operation is performed, the fine adjustment operation is also unnecessary. When the angle setting operation is completed, the wedge member may be removed. Note that the protruding wall W and / or the stopper member ST also acts as a member for preventing the panel lower end portion from being lifted during a strong wind or an earthquake.

<Fifth Embodiment>
Next, a fifth embodiment will be described with reference to FIG. FIG. 19 (a) is a partial cross-sectional side view of the solar tracking solar energy receiver device, and is a side view seen from east to west. FIG. 19B is a partial cross-sectional side view showing the shaft rotation joint portion of the beneficiary member rotation shaft support structure of the external device. The beneficiary of the device is depicted as being a solar water heater heat collecting panel 110 (10). This embodiment is drawn in a similar manner to the third embodiment (FIG. 14) in appearance, and the panel rotation shaft structure (joint portion) is greatly different from FIG. The rotary shaft structure is in principle similar to that of the fourth embodiment shown in FIG. The structure is as follows.

One of the connection frames FF is fixed to the lower frame, for example 11i, of the upper part (the other) 1b of the panel 10. Then, one of them is provided with a shaft support portion having a concave spherical portion 27Q. The connection frame FF has a T-shaped vertical cross section, and is fixed to the frame 11i (see FIG. 5) together with one of the FFs via a triangular reinforcing part FS extending from the T-shaped horizontal part FH. The panel 10 is integrally formed. The other end portion of the frame FF is provided with a vertical portion FF1 perpendicular to the horizontal portion and a shaft portion 27d 'attached in contact with the horizontal tip portion FH1. A stopper 27S is provided below the shaft portion 27d 'in the same manner as in FIG. 18, and chamfered portions 27M are provided at three upper portions (east, west, north, and west). A shaft seat 25 having a convex spherical bearing portion 25Q fitted to the concave spherical portion 27Q is provided in the same manner as in FIG. The shaft seat 25 is fixed to the bottom surface bb of the substantially L-shaped holding member 3d '. The holding member 3d 'has a horizontal axis AH at the lower triangular tip bt thereof, and is attached to a holding member mounting seat 6Y5' having a shaft hole corresponding to the horizontal axis AH so as to be rotatable in the elevation direction. The mounting seat 6Y5 'is fixed to the vertical wall of the column 6Y. A stopper body ST7 is fixed to the middle vertical wall of the column 6Y so as to protrude toward the center of the panel via its mounting seat STB. This stopper body ST7 has an inverted T-shaped section in a short direction cut vertically (see also FIG. 21). The front end portion STT of the stopper body ST7 is provided to face the horizontal front end portion FH1 of the frame FF, and has a clearance CLS between the lower surface S7 of the front end portion STT and the upper surface S8 of the horizontal front end portion FH1. . The size of the clearance CLS is set smaller than the spherical radius of the bearing portion 25Q. By doing so, even if the fitting between the shaft portion and the bearing portion is likely to come off due to an earthquake typhoon or the like, the separation can be prevented. An azimuth angle detection sensor (sun tracking sensor) SE1 may be provided on the lower surface S7 of the distal end portion STT. You may provide this sensor in another site | part.

The holding member 3d 'is held in such a manner that its vertical portion abuts against the mounting seat STB of the stopper body ST7 and is pressed against the support column 6Y, and the receiving member is used. In order to be able to be pressed, a hole dh that penetrates the horizontal portion of the stopper body ST7 is provided in the vertical middle portion of the holding member 3d '. Explanation of the arrangement of PS, FP, FP1 and the like connected to the upper end of the panel 10, and explanations of 12, 17, 9, 92, 95, ST8, and STP provided below (one side) 1a of the panel 10 As described above. The length and position of the leg 12 are as shown in the figure and are slightly different.

The shaft tower includes a shaft tower base portion 8 and a main body portion (post 6Y) such as a shaft, and the shaft tower base portion 8 is the same as FIG. FIG. 19 shows the inside of the hemispherical dome (shaft tower base 8) in detail. The dome 8 is erected on the roof of a house or a building, for example, and a building 80 as a roof entrance / exit is provided adjacent to the dome 8. The building 80 is provided with an entrance door 808 on the north side. In the dome 8, a step STEP with the center of the dome as the uppermost step is provided. In the building having a rooftop, vertical pillars Y5, Y6, Y7 and horizontal pillars and / or rooftops F1, F2 and a landing 97 as shown in the figure are provided.

This embodiment is provided with an emergency safety device SAF (see FIGS. 19 and 20) that is in principle the same as FIGS. 15 to 17, and this safety device is further evolved from the former. . This point will be described with reference to FIG. Before that, the apparatus of FIG. 15 had to operate the safety device after the panel 10 was in the state of facing substantially south. “Operating in a substantially south-facing state” means that in the state other than FIG. 15A, for example, in the west-facing state, the back surface of the panel can be seen in FIG. 15A. In this state, when the lever LB is operated to drive the driving piece K1 so that the protrusion 3d9 is in a free state, the heel is released and the panel 10 is in a collapsed state so that the inclination angle i is reduced by its own weight. . At this time, since the direction of the axis 3X (see FIG. 15) and the rotation direction of panel collapse are orthogonal, they cannot be collapsed. If there is a clearance CL (see FIG. 16b) around the shaft 3c1, the panel can move in proportion to the size of the panel by the clearance. Depending on the amount of this clearance, the panel movement in the direction in which the panel inclination angle i becomes small and the movement of the wheel trace at the lower end of the panel to the outside even in the system of FIG. Allow. This allowance is referred to as the panel twist angle direction allowance. This allowance is slight, and the limit of the twist inclination angle of the panel is 1 to 2 degrees, which allows non-horizontalness with respect to the entire installation surface.

Fifth Embodiment In FIG. 19, not only the tolerance of the twisting angle of the panel is greatly allowed (30 degrees to 45 degrees), but also the safety device works if the lever LB is tilted regardless of which direction the panel 10 faces. It is like that. Moreover, the lever can be operated either manually, semi-automatically, or fully automatically.
FIG. 20 is a mechanism for locking or unlocking the rotation center position of the panel 10, and is a detailed perspective view seen from the north side of the safety device SAF in an emergency such as an earthquake typhoon, and is also a modification of FIG. . The safety device SAF is attached to the north-side standing surface of the column 6Y shown in FIG.

This safety device SAF has a function and mechanism for switching between a metastable state (panel rotatable state) and a stable state (locked state) of the panel by the driving piece K1. The driving piece K1 composed of the front end portion K11 and the rear end portion K12 is driven so as to be freely inserted into and removed from the through holes provided in the protrusions 3d9 and 3dp projecting northward from the holding portions 3d and 3d ′ in FIGS. The drive piece is detachably provided in a through hole h2 (not shown in FIGS. 19 and 20) penetrating in the east-west direction. The driving piece K1 is always allowed to pass through the through-hole h2 and the through-hole h1 opened in the rib 6Y2 in the rotatable state of the panel, thereby enabling the panel 10 to be in a metastable state. . The horseshoe-shaped holder K that holds the drive piece K1 in the horizontal direction so as to be freely inserted into and removed from the holes h1 and h2 is fixed to the rib 6Y3 via its seat KB as in FIG.

The lever shaft base end portion LBL is freely rotatable to the rib 6Y3 of the support column 6Y via a shaft seat (bearing) 6Y4 having a universal joint function and a shaft portion below the flange portion composed of the drive piece K1 and the holder K. It is attached to. The lever LB is connected to the rod-like upper portion LB via a wide plate-like main body portion LBB that is bent immediately from the base end portion. An intermediate portion of the main body portion LBB is provided with a laterally long hole opened in the horse's top surface of the holder K and a laterally elongated hole h44 that is always in a penetrating state when the panel is in a rotatable state (the state shown in FIG. 20). An L-shaped elongated hole h33 that passes through the shaft portion ac2 of the actuator welded and fixed to the drive piece K1 is provided immediately above the elongated hole h44, and the elongated hole that opens on the top surface of the holder K opposite the elongated hole. K22 is provided. Three protrusions K5, K5, and K5 fixed to both ends and the center of the upper wall surface rising from the seat KB of the holder K are provided, and the protrusion K5 has a top surface with a lever wide plate. It arrange | positions so that the through-hole h55 of the corresponding site | part provided in the shape main-body part LBB may be penetrated. The height of the top surface of the projecting piece K5 is set to a predetermined height described later. In the drive piece K1, roller type bearings R51 and R52 are rotatable on the vertical surface of the front end K11 facing the back surface K2 of the top surface of the holder K, and the roller type bearing R54 is rotatable on the vertical surface of the rear end K12. It is embedded and formed. A roller-type bearing R53 is also embedded in the drive piece vertical surface facing the rib 6Y3 of the support so as to be rotatable at an intermediate position between R51 and R52.

In the lever bar-like upper LBS, a vertically long hole LB penetrating in the column direction is formed. Opposite to this, an Ω-type spring 9S attached to the attachment seat 6Y9 is provided on the rib 6Y3. The lever LB is locked by the lever locking means by the spring 9S and the hole LBh. That is, in the metastable state of the panel 10, the spring top portion 9S5 is elastically engaged so as to slightly protrude from the hole LBh. The spring 9S includes attachment portions 9S1 and 9S2 to the attachment seat 6Y9, rising portions 9S3 and 9S4, and a top portion 9S5, and has elasticity at portions other than the attachment portions 9S1 and 9S2. The lever includes a motor drive unit MD5 that is fixed below the intermediate portion of the lever main body LBB. This unit MD5 is a geared motor composed of a motor, a worm, and a gear, and its case body is fixed to the lever body. The gear G5, which is an output unit, transmits the torque force to the rack-like teeth provided on the top surface of the drive piece K1 and moves the drive piece K1 horizontally by rotating the shaft part G51 by a motor. The escape portion of the actuator shaft ac2 at this time is entrusted to the laterally long hole K22, and the laterally long hole K22 has a length equal to or slightly longer than the horizontal movement length of the drive piece K1.

When the driving piece K1 is moved to the left (eastward) by the gear -G5 from the state shown in FIG. ) Is released from the hole h1. This is because the position at which the concave spherical portion 27Q pushes the bearing portion 25Q is shifted in the horizontal direction (and below the panel) from the axis AH (horizontal position shift). When the projection 3dp is detached from the hole h1, the panel 10 lowers its center of gravity (shift in the vertical direction) and simultaneously moves in the horizontal direction. As a result, the stopper piece STP at the lower end of the panel comes into contact with 94 or 901 (see FIG. 18). That is, a firmly fixed state is formed by one point at the upper end of the panel and two points at the lower end of the panel. Since this fixed state can be said to be a kind of “wedge driving state” in principle, it forms a stable fixed state. Since the panel upper end receiving part structure is composed of 27Q and 25Q spherical surfaces, the above "horizontal misalignment" and "vertical misalignment" are possible no matter which direction the panel is facing (for example, eastward) I have to. If the panel 10 faces either east or west, the protrusion STP at either end on the lower side of the panel is difficult to abut on the rail side surface 94. However, either one of them always abuts on the rail side surface 94 at two points. Since the abutting more than the one-point abutting force at the time should have occurred, the panel fixing state (stable state) is still formed. At this time as well, the “wedge strike state” is formed.

When returning to the panel rotatable state after the emergency situation is over, the 3d4 is moved upright and 3dp (3d9) is inserted into the hole h1, and an electric button described later is pushed, or manual operation (described later) is performed. Then, K11 fits into the hole h2, and the panel returns to the original rotatable state. When the lever LB is manually operated to disengage K11 from the hole h2, the spring 9S is disengaged from the hole LBh by operating the LBS away from the column 6Y. At this time, the gear G5 and the spur gear (rack) of the drive piece K1 are disengaged, and the peripheral portion of the hole h33 comes into contact with the head of the actuator fixed to the shaft portion ac2 with the screw N55. The lever LB will not fall. When the lever LB is moved to the left (eastward) in this state, the lever rotates about LBL, and the actuator shaft portion ac2 pushes the left end surface of the hole h33, so that the driving piece tip portion k11 moves to the left. Moving. The subsequent lock state release operation and lock state return operation of the panel 10 are the same as described above, and will be omitted. The roller bearings R51, R52, R53, and R54 described above act to make the movement of the driving piece K1 smooth. That is, the larger the panel 10 is, the more friction is generated between the driving piece tip K11 and the wall surface of the hole h2, and the bearing is provided to make it difficult to drive. ing. The bearing may not be provided depending on the size of the panel 10 and the size of the positional deviation.

<Example of azimuth angle detection mechanism>
FIG. 21 is an exploded perspective view showing an azimuth angle detection mechanism, which is shown as being suitable for the embodiment of FIG. 19, for example, and includes a detection unit and a sensor drive unit. The detection unit includes an azimuth detector (sensor) SE1 having mounting legs SEb and SEc, and a crank-type driven unit ac7 fixed to the rotation shaft end SEa of the sensor SE1. It consists of an L-shaped mounting portion FL and a cylindrical drive rod ac8 secured at one end to the vertical portion FLb by spot welding. The sensor SE1 is fixed to the lower surface S7 of the distal end STT of the emergency panel detachment preventing stopper ST7 (FIG. 19) located at the upper center of rotation of the panel 10 with a screw N7. The sensor SE1 may be anything as long as it can detect the rotation angle, and may be, for example, the rotation angle corresponding Gray code generator shown in Non-Patent Documents P40 and P51. The driven portion ac7 is made of an L-shaped piece, and includes a shaft end holding portion acA, a vertical portion acB extending its free end vertically, and a rod receiving engagement hole formed by horizontally bending the upper end of the vertical portion acB. It consists of non-driving piece acC with an ach.

The driving rod ac8 of the sensor driving portion is made of a stainless steel rod having spring properties, and when the tip of the driving rod ac8 is rotatably installed on the bearing portion 25Q, the driving rod ac8 is fitted into the engaging hole ach to be driven to rotate. The mounting portion FLa of the sensor driving portion FL is fixed to the top surface S8 of the tip with screws LS1 and LS2. Thus, when the drive rod ac8 fits into the engagement hole ach and the panel 10 rotates, the panel 10 rotates while having the clearance CLS. In an emergency, when the holding member 3d ′ supporting the other (upper end) of the panel 10 is to be tilted, the elasticity of the drive rod ac8 causes the rod to be deformed and its tip is detached from the engagement hole ach. A state equivalent to the state indicated by the dotted line in FIG. When returning the panel, the rod ac8 may be elastically deformed and reinserted into the engagement hole.

Even if the accident occurs when the holding member 3d ′ does not fall down due to some accident, and the panel rotation joint portion is likely to come off (a situation where 27Q is lifted from 25Q occurs) The upper surface S8 is in contact with the lower surface S7 while destroying the sensor SE1, so that the shaft portion is not disengaged. By constructing in this way, not only can the damage be minimized, but the proof that the phenomenon is so strong that the phenomenon of rising due to an earthquake typhoon or the like will become obvious by the destruction of the sensor. This makes it possible to clarify the assurance level of the present beneficiary device. Alternatively, even in the above case, if it is desired to prevent the sensor from being destroyed, the sensor destruction preventing portion STS indicated by the dotted line may be formed so as to protrude from the lower surface S7. As a result, even when the above emergency occurs, the upper surface S8 tries to contact the lower surface S7, and this destruction comes into contact with the prevention portion STS, so that the sensor can be prevented from being destroyed.

<Best mode of emergency safety device>
FIG. 22 is a perspective view showing the best mode of a safety device (panel shaft rotary joint portion) that increases the safety probability in an emergency such as a typhoon, a tornado, and an earthquake. 14 can be operated only in the south direction in combination with FIGS. 15, 16, 17, and 20, and in FIG. 19, in the south direction in combination with FIGS. 17, 18, 20, and 21. It was possible to operate ± 45 degrees, 90 degrees in total. If the apparatus shown in FIG. 22 is used, if the strut 61 can be thinned while maintaining the strength, the rotatable range can be as close as possible to the southward direction ± 180 degrees and a total of 360 degrees. A reasonable range for satisfying the above condition would be about ± 100 degrees southward, about 200 degrees in total. The panel shaft rotary joint portion JT of FIG. 22 will be described in comparison with FIG. 15A or JT of FIG. 22 can be said to be equivalent to a joint portion in which the JT attached to the attachment seat 6Y5 in FIG. 15 can be rotated in the azimuth direction together with the attachment seat. In other words, an alternative to the mounting seat that is deformed to rotate is a disc-shaped rotating seat 615 that is mounted on the upper surface of the support column 614 so as to be freely azimuthally displaceable. The column 614 is the column 61 in FIG. 7, the column 61 in FIG. 14, the column 6Y1 in FIG. 15, the column 6Y in FIG. 19, and the column 6Y in FIG. The column is a column connected to the column 61 by a coupling member 611, and is erected, for example, with a distance equal to or larger than the radius of the rotary seat 615 from the column 61 and from the center thereof.

The rotary seat 615 is rotatably mounted on the upper surface of the column with a ball bearing (not shown) interposed between the rotary seat 615 and the upper surface of the column 614. On the upper surface of the rotary seat 615, a vertical column 616 made of a prism, a square pipe or a U-shaped member is vertically suspended so as to be in contact with the inner surface of the support column 3dv. Shaft seats 617 and 618, such as rabbit ears, which are coupled to the lower portion of the vertical column 616, are integrally provided on the upper surface of the rotating seat 615, and the shaft seat hole and the joint body 3da are vertically supported. The column part 3dv is rotatably coupled via a shaft body XX that is passed through holes provided in the leg parts ca7 and ca8 of the parts 3de and 3dg. The column 3dv is a column having a U-shaped horizontal section composed of three vertical support portions 3df (intermediate back portion), 3de, and 3dg. The vertical support portions 3de and 3dg on both sides extend from the bottom (near the shaft body portion). A triangular displacement stabilization plate portion REG protruding in the direction of the column 61 in FIG. 22 is integrally provided. A connecting portion RL that connects the upper ends of the stabilizing plate portions REG on both sides closer to the support column 61 is provided. Accordingly, the column portion 3de having a U-shaped horizontal section is erected so as to freely open in a V shape so as to cover the vertical column 616. The upper surface of the vertical column 616 is integrally coupled to a columnar upper portion 619, and the columnar upper portion 619 includes a shaft portion 61j protruding integrally upward from the upper surface. The shaft portion 61j is formed by being rotatably fitted to a shaft recess provided on the lower surface of a columnar column 613 integrally connected to the column 61 by a connecting member 612.

A panel support holding portion 3db that protrudes in the horizontal direction (panel direction) is integrally provided on the intermediate portion back portion 3df of the support post portion 3dv. Is configured. The holding portion 3db is formed in an annular wall shape or a four-way wall shape, and is feedback coupled to the back portion 3df. Two angular support portions 3dc and 3dd that are spread out on the annular wall portion of the holding portion 3db that is far from the back portion 3df are integrally formed. One wing portion 3a1 is coupled to the two. The panel 10, 10S, 110 or the panel attachment member 11 is attached from the attachment hole h3a with screws as shown in FIG. 15, for example. A vertical elongated hole 3d5 ′ through which a communication pipe 4 communicating the heat collector (10, 10S) and the tank (5, 50) is passed is provided on the back portion 3df of the vertical support portion 3dv. A vertical hole 616h is also provided in the vertical column 616 at the same vertical position as 3d5 ′, and a vertical hole 6Y8 is also provided in the vertical U-shaped rear surface of the column 61. The pipe 4 passes through the long holes 3d5 ', 616h and 6Y8 and is connected to a panel rotating body and a tank (not shown). An electromagnetic actuator SL5 is fixed inside the columnar upper portion 619, and the drive piece PG5 is disposed so as to hang down from the lower surface of the 619.

With the above configuration, for example, the electromagnetic actuator SL5 receives a command signal from the abnormality detector 798 shown in FIGS. 25A and 25B described later or the earthquake information acquisition means EQI in FIG. When the drive piece PG5 is driven upward, the upper end portion of the back portion 3df and the drive piece PG5 are not fitted (contacted). Then, by the force (gravity) that the wedge function part of the gravity wedge mechanism tries to descend downward, the potential energy of the solar panel rotating body is consumed and the joint body part 3da is pulled to the panel side and the lower side, and the support part 3dv Falls on the panel side (this is called the panel collapse state). Then, the support portion 3dv and the vertical column 616 are V-shaped and stopped. This is because the stopper STP contacts the side surface 94 at the lower end of the panel (FIGS. 15 and 19). In the process of or when the support portion 3dv and the vertical column 616 become V-shaped, the triangular stabilizer plate portion prevents the XX axis and the shaft 3c1 from being twisted or prevents the twist. The REG functions stably in contact with the vertical support portions 3de and 3dg on both sides. The connecting portion RL also serves as an auxiliary portion that assists the two stabilizing plate portions REG on both sides so that the stabilizing plate portion REG is not twisted and opened when the panel collapses. The connecting portion RL is designed to face the side surface of the vertical column 616 with a predetermined clearance (for example, 1 to 5 mm) when the panel is collapsed. As a result, even if the stopper STP is deformed by an external force at the time of a large disaster, the connecting portion RL serves as a stopper and can prevent further collapse of the panel. .
In addition to the above-described configuration, in the panel collapse state, a plunger PG7 that enters from the stabilizer plate REG toward the support portion 3dg from the stabilizer plate REG to the outside of the panel-side standing surface of the vertical column 616 is provided. An electromagnetic actuator SL7 may be provided. The electromagnetic actuator SL7 may also be provided in the vertical support portion 3dg. In this case, when the plunger PG7 has a through hole through which the plunger PG7 is inserted and removed from the stabilizing plate portion REG, and the panel is stopped by the stopper mechanism at the lower end portion of the panel, the joint body portion 3da is The vertical column 616 is fixed at a position between the plunger PG7 and the connecting portion RL. Therefore, once the panel collapse occurs, the panel may maintain the panel collapsed state even if the PG is raised by 980 gal or more or strong wind unless an operation of retracting the plunger PG7 occurs. it can. It should be noted that a slight clearance is provided between 616 and PG7 and 616 and RL. In the state where the wedge function as described above is exerted, it constantly surpasses earthquakes and strong winds.

In this embodiment, regardless of the direction of the panel from east to south to west, the gravity wedge action works in the direction in which the panel lies, and the panel rotating body is securely held at the upper and lower two points. Can be. The drive signal to the electromagnetic actuator may be modified with the command signal and driven with a plurality of pulses as shown in FIG. 25 (e) PLS1. The upper part 1B of the panel rotating body (1, 100, 110) in a normal state where the abnormal situation or the emergency situation has been pushed up is pushed upward so that the upper end of the back part 3df and the driving piece PG5 are fitted again. Can be restored. The explanatory texts related to FIGS. 25 and 26 should be read again after reading the explanatory text to be described later.

<Sun tracking drive control unit>
An example of a drive system that is a central part of the sun tracking drive unit will be described. FIG. 23 is a block circuit diagram for rotating a rotary solar utilization device, which is a fully automatic solar tracking system. This system sets TM1 to chime mode and TM2 and TM3 to alarm mode among three commercially available digital quartz watches (timer circuits) TM1, TM2, and TM3. In this system, at the time of TM3 (for example, 7:30 am), the mode switching control circuit 765 switches from the sunset mode to the sunrise mode. The forward progress control circuit 763 is switched from the prohibit mode to the prohibit cancel mode by the mode signal at this time. When a chime signal is generated every hour from TM1 in this state, the switch SW1 that switches the main circuit of the motor M1 that rotates the solar heat utilization device is automatically switched by means such as a relay in the forward advance control circuit 763. Switch to the upper side. Then, the motor M1 rotates in the forward stepping direction, and the solar heat utilization device rotates by a predetermined angle in the direction in which the azimuth angle changes, that is, from the east to the south and to the west. When the motor rotates by a predetermined angle, a predetermined angle is detected by a rotation position sensor to generate a predetermined angle rotation end detection signal (step signal), and this signal is returned to the forward step control circuit 763, and SW1 is reset to stop the rotation.

Then, after 1 hour, a chime signal is emitted again from TM1, and using this signal as a trigger, the motor M is moved forward in the same manner as described above to rotate the solar heat utilization device by a predetermined angle. When this operation is repeated n times (n can be changed by TM2 and TM3) until the evening, a limit signal saying “I can't go any further” is sent from the rotational position sensor to the forward step control circuit 763. Depending on the time setting of TM2 and TM3, this limit instruction signal may not be output. In the meantime, when the sunset time (for example, 7:30 pm) that is the setting time of TM2 is reached, TM2 generates a sunset command signal, and switches the mode switching control circuit 765 from the sunrise mode to the sunset mode. In response to this mode switching, the forward step control circuit 763 is set to a drive prohibited state. Similarly, the reverse step control circuit 764 is excited, and the main circuit switch SW2 of the motor M1 is automatically switched to the upper side by means such as a relay. As a result, the motor M1 rotates in the reverse direction, and the solar heat utilization device rotates non-stop from the west to the south and east to the basic position. When the basic position is detected by the rotational position sensor 768, the reverse advance control circuit 764 is stock-controlled by this signal, and the switch SW2 is automatically returned to the lower side. Then, at the set time of TM3 the next morning, the mode is switched to the sunrise mode, and the same process as described above is repeated endlessly throughout the year.

A display control circuit 766 and a display (not shown) are provided so that the current position of the outdoor solar heat utilization device can be detected indoors. The circuits 763 to 768 are composed of about 3 to 40 electrical and electronic components. The explanation in FIG. 23 so far is an explanation of a portion surrounded by a one-dot chain line. For more details, please refer to my book mentioned above (especially P55). In other words, the existing system can be used as it is as the azimuth rotation system. A portion surrounded by a two-dot chain line in FIG. 23 to be described next is a portion newly added this time, and a new function is added as an entire circuit to constitute a new system.

A new function by the added new part is that the elevation angle of the panel 10 is controlled, and the control is performed by the optical sensor ph. In the overall system shown in FIG. 23, the azimuth angle control is an intermittent solar tracking method using a timer, and the elevation angle control is a light source direction tracking method using an optical sensor. In addition, a timer / light tracking hybrid control system is used in which the timer azimuth angle control is driven in preference to the light tracking elevation angle control. The configuration will be described next.

The optical sensor ph is a photodetector in which, for example, cds or the like is assembled as a resistor bridge circuit, and is provided on the upper surface of the panel 10 as shown in FIG. The detector output lines L1 and L2 are taken out as signals varying from + V1 to -V1. The voltage between L1 and L2 is 0V when there is even light input to the U / D light detection unit or when there is no light input. Only when there is a difference in optical input, + EV and -EV are generated between L1 and L2. If U is strong light input and D is weak light input by the waveform shaping / separating circuit 702, the line L3 is + eV (L3 = “1”), L4 is 0V, and L5 is 0V as shown in the time chart of FIG. If U / D is the opposite, L3 = 0, L4 = 0, L5 = + eV (L5 = “1”), and L3 = 0, L4 = 1, L5 = 0 when the light quantity is balanced. Waveform shaping is performed, and each signal is branched to each line. If the panel 10 faces downward from the sun position (the panel stands), + eV (L3 = “1”) is generated in L3. The L3 signal is used as one input of the AND circuit 705, and the other of the AND 705 delays the relay coil + side line L6 disposed in the forward step control circuit 763 slightly (for example, 1 μs to 1 ms) by the delay circuit 704. The output L8 is used as the other input.

Then, the output of the AND 705 is input to the set terminal S of the flip-flop circuit (FF) 710. That is, the FF 710 can be in the set state only when L8 becomes “1” when the motor M1 changes the azimuth angle of the panel with the chime signal every hour. As a result, the Q of the FF 710 becomes “1”, and this signal is amplified by the current amplifier 714 to turn on the relay UX 717. As a result, the contact SW3 is switched from the bottom to the top. Then, the panel turns up by the rotation of M2 by the motor and faces the sun. Specifically, the tower body 22 is moved downward by the geared motor GM so that the inclination angle i of the panel 10 of FIG. In this case, the motor M2 is equivalent to the motor used for the geared motor GM. Since the output of the sensor ph becomes 0 V when the sun is directly facing, L3 = “0”, L4 = “1”, L5 = “0”, and L4 = “1” is the reset terminal of the FF 710 via the OR circuit 706 R is input. As a result, Q = “0” turns off the relay, returns SW3 to the original state, and stops the motor M2. That is, since the signal line L7 obtained by inverting the voltage signal applied to the relay coil output + terminal in the circuit 763 controlled by the timer circuit TM1 by the inverter 703 is input to the reset terminal via the OR 706 in the FF 710, the motor M1. Is controlled so that the reset state is released only for a short period of time when it is intermittently driven every hour. Therefore, even if the optical sensor difference signal is generated at other times, it is ignored and the panel 10 is prevented from moving up and down. If the panel 10 faces upward from the sun position during the driving time of the motor M1 (L8 = “1”), L5 = “1” is one input, and L8 = “1” is the other input. By setting the FF 712 by the output “1” of 707 and outputting Q = “1”, the signal is amplified by the amplifier 716 to turn on the relay 718, and the contact SW 4 is switched from the bottom to the top. Then, the panel 10 turns downward by the rotation of the motor M2 and faces the sun. Then, since the sensor ph output becomes 0 V, L3 = “0”, L4 = “1”, L5 = “0”, and the L4 signal is input to the reset terminal of the FF 712 via the OR 708 and reset. As a result, relay DX718 is turned off, SW4 is turned off, and motor M2 is stopped.

By the way, in FIG. 1, as an example, the maximum inclination angle i of the panel is about 45 degrees and the minimum inclination angle i1 is about 15 degrees (the reason is as described above). In such a variable angle range, the solar positive diagonal of the panel may exceed the upper and lower limit values depending on the season or a predetermined time of the day. In this case, even if the panel reaches the upper and lower limit values, U / D Unbalance occurs in the optical difference signal. As a result, an instruction signal to go further (lower) is generated. In this case, each output of the limit sensor (which may be a switch) that generates “1” S7 is used as a reset terminal of FFs 710 and 712 as shown in the figure. FFs 710 and 712 are continuously reset. As a result, the motor M2 continues to stop rotating. S7 is a limiter including a plurality of limit sensors, and includes limit sensors S71 and S72 that can be automatically restored under a predetermined condition, and limit sensors S73 and S74 that are not automatically restored and can be manually restored. For example, when the limiter S7 is implemented in the first embodiment, 61g in FIG. 7 is provided on the facing surface on which 229 in FIG. Since the limiter is provided corresponding to the vertical position and the relay is represented with respect to the orientation of the panel, the display is conceptually opposite to each other.

For example, near the evening, the lower position limit sensor S72 generates “1” in a state in which a downward instruction signal continues to be output, that is, i = 45 degrees. This signal is input to the R terminal of the FF 712 via the OR 708, and the motor M2 is continuously stopped. To release from this state, when the sun rises the next morning, L3 = “1” by the sensor ph causes Q = “1” of the FF 710 and the motor M2 is driven (driven in the direction to lay the panel). Is called. After a slight rotation, S72 = "0", the limiter is released (limiter automatic return), the optical tracking control system within the above upper and lower limits is restored, and the tracking continues. The above is the operation when it is sunny.

At the time of intermittent panel azimuth driving every hour, a light difference signal may not be output due to cloudy or rainy. In this case, in this system, the panel 10 is left at the previous elevation position. In addition, during the above driving, if it is clear from the middle and there is an optical difference signal output, FF710 or FF712 is activated by L4 at the timing regulated by the lines L3 and L5, and the intermittent panel The panel 10 is driven by M2 so that the panel 10 faces the sun from a sunny time during the driveable time. The speed ratio between the motors M1 and M2 is such that the speed of the M2 is higher, and if the weather is far clearer, the panel's front (up and down movement) will follow before the intermittent azimuth stop position of the panel by M1. I try to arrive. By doing in this way, even if it is clear on the way, most can catch up. For example, even if there is no reaction about twice due to cloudiness, etc., when it is next sunny (after 3 hours), it can catch up to about 2/3 at a time. Even if you can't catch up unfortunately, you don't follow up deeply, and it's a system that you trust the next time.

Further, as a safety measure, a limit sensor S74 that operates at an upper limit (with a lower solar altitude) than the limit sensor S72 is configured to make a through or break between the anode terminals T3 and T4 of the motor drive relay 718, and the limit sensor. A limit sensor S73 that operates at a lower limit (a state in which the solar altitude is higher) slightly than S71 may be used to break or break between the anode terminals T1 and T2 of the motor drive relay 717. If such measures are taken, even if the solar tracking system fails, it is possible to prevent destruction of the tower, building, panel, etc. Incidentally, the installation positions of the limit sensors S73 and S74 are set to the maximum inclination angle i and the minimum inclination angle i1 of the panel 10 or slightly inside thereof. Also, in the figure, switches SWu and SWd in the two-dot chain line are panel forced movement switches. In particular, SWu is a switch for manually laying the panel (turning it up) at the time of failure or typhoon, earthquake forecast, and switch SWd is a switch that activates the panel.

<Panel auto lock system>
FIG. 25 shows a solar panel auto-lock system in an emergency such as an earthquake typhoon. (A) The figure shows that in the embodiment of FIG. 19 adopting FIG. 15 or FIG. 19 or FIG. 22, when the panel is about to be detached from the installation surface of the rail portion etc. in an emergency, it will not be blown. FIG. 6 is a modification showing a configuration in which the is fixed to a fixed body (installation surface), and is a mechanism diagram showing details of a panel lower part. (B) is a principle diagram of a detector for detecting an emergency. (C) The figure is the principal part of a solar panel auto-lock system, and is an example of a circuit system. (D) is a figure which shows a key lock part. FIG. 4E is a time chart for explaining the operation. (F) FIG. 19 shows a circuit for controlling the panel collapse state in the embodiment of FIG. 19 adopting FIG. 22, even if a factor causing vertical movement occurs in the event of a panel collapse in an emergency situation. ing.

If the (a) figure is regarded as a modified example of FIG. 19, for example, the (a) figure corresponds to a figure seen from an oblique rear side so that the back surface of the panel can be seen. In (a), one end of the lower frame 11a of the lower frame 11a of the panel 10 (see FIGS. 1 and 5) is attached to the lower part of the protrusion 11p fixed to the surface facing the lower end of the panel 10 and the other end (not shown). The movement support member (rotating wheel) 16 and the movement propulsion unit (motor drive unit) MDU are assembled (assembled) in a frame 79 that is engaged with a protrusion (not shown) that hangs from the lower surface of the panel. The mobile unit MVU is movably mounted on the rail portion 90. The rail portion 90 is placed on a placement surface 9 such as a rooftop via a sleeper 96, and the sleeper 96 is formed integrally with the rail portion 90. The rail portion 90 is formed of a square frame and has reinforcing triangular frames 97 and 98 welded to both sides thereof. A motor drive unit MDU connected to a wheel shaft J fixed to the wheel is fixed to the frame 79. A stopper body ST having a stop portion STP is also fixed to the frame 79. Attachment frames 791 and 792 for attaching the wheel 16 to the lower surface of the frame 79 of the movable body unit MVU are fixed, and an L-type attachment member 793 is attached to the outer frame 791 with screws 794. A sensor attachment member 797 is screwed to the hanging piece 793 with a screw 794.

When the panel 10 is detached from the installation surface 92 of the rail portion in the emergency, a panel separation detector (sensor) 798 for sensing the panel separation is fixed to the mounting member 797. As shown in FIG. 25B, the detector 798 is constituted by a self-inductance change detection type sensor, for example. The detector 798 is composed of a coil L1 (L2) in which a copper wire (conductor) is wound around a core cr made of a ferromagnetic material such as iron or ferrite and having a high relative permeability, and is formed in, for example, an inverted U shape. The both ends of the core cr are arranged opposite to each other with a gap GP (or clearance) provided on an installation surface 92 made of, for example, an iron plate. The detector 798 and the installation surface 92 form a self-inductance change detection type sensor. Two sensors are installed at both ends of the panel 10 in the width direction of the lower surface, for example, near the wheels 16 and 17. Accordingly, the coil L2 is provided in the vicinity of the wheel 17.

(C) As shown in the figure, one ends of the coils L1 and L2 are connected to one end of the AC power supply 781, and the other ends of the coils L1 and L2 are connected to the other end of the power supply 781 through predetermined resistors r5 and r6. One ends of the resistors r5 and r6 are grounded, the anode ends of the resistors r5 and r6 are coupled to one end of the resistor r3 through the diodes Di1 and Di2, and the other end of the resistor r3 is coupled to the transistor Tr1 through the diode and the resistor r3. Connect to the base. Further, the Tr1 is connected to the base from the DC power source + V through the switch SW7 and the resistor r2 that defines the base current when the SW7 is turned on, and is connected from the + V to the collector through the resistor r1 between the base and the emitter. Is connected to the capacitor c1. In this way, a large change in the collector voltage can be regarded as a detection output of panel separation detection from the ground plane 92. Therefore, the detection coils L1 and L2 to the transistor Tr1 are referred to as a detection signal generation unit. That is, when the gap GP is increased in one or both of the coils L1 and L2 attached to the lower surface of the panel 10, the inductance value of the coil is decreased. There are many factors, but the biggest factor is that the apparent permeability changes greatly. In other words, the panel separation operation can be regarded as an operation equivalent to the insertion and removal of the cores cr1 and cr2 in the coils L1 and L2 shown in FIG. In the extreme, if the relative permeability in the air is 1, it is said that the iron has 200 to 1000 times, so the self-inductance L is proportional to μ (mu), so it is equivalent to complete insertion and removal. Even if this is not possible, it is possible to detect a change of 10 to 100 times that of 1/10, and the change can be detected by the detection signal generator.

(E) Further description will be made with reference to the drawings. The signal 1 is a signal generated at the resistor r5 or r6 or the anode terminal of the diode Di1 or Di2, and within the range of T1 during normal use, if the voltage applied to both ends of the coil is Ve, Ve = L × (di / Dt), and since the inductance L value is large, in terms of impedance, the coil is larger than r5, the r5 anode voltage is low, and an alternating current signal such as T1 continues to be generated. If r5 and r6 are set to values that do not reach the diode barrier voltage value of 0.6 volts at that time, the base voltage is normally 0.6 volts or less and the transistor Tr1 is turned off. When the panel is detached from the ground plane due to a large earthquake typhoon, etc., the self-inductance of the coil decreases and the impedance decreases. Then, since the current flowing through the resistor r5 (r6) increases, the voltage across the resistor r5 (r6) increases, and a large amplitude voltage is generated as indicated by T2 of the signal 1). This is rectified by diodes Di1 and Di2 and output.

(C) According to the configuration shown in the figure, the diodes Di1 and Di2 certainly rectify the AC signal, but at the same time, detection of one or both of the detection signals from the two detectors (coils L1 and L2). A signal is output. In other words, this diode functions as both a rectifying action and a diode OR circuit. The rectified pulsating signal accumulates its electric energy in the capacitor C1 via the resistor r3, and gradually increases the base voltage (2). Although this rising curve depends on the frequency of the AC power supply, for example, if it is 50 to 10 KHz (but below the frequency that does not cause magnetic saturation), Tr1 can be turned on instantaneously for about 1 ms to 100 ms. When Tr1 is thus turned on, the signal is output from the collector as signal (3), inverted by inverter IN1, and differentiated by differentiation circuit DF to obtain signal DF as signal (4). The output Q of the flip-flop circuit FF780 set by this rising signal is amplified by the amplifier AMP1 to drive the relay x1, and a solenoid driven by the relay switch SX1 with a signal driven with a predetermined pulse width such as signal (5). SL1 is driven. The output Q is delayed by the delay circuit D1 (for example, 0.1 to 0.2 seconds) and amplified by the amplifier AMP2, and the relay X2 is driven to the relay switch SX2 by a pulse signal like the signal (6). To drive the solenoid SL2. When the FF 780 is reset by a delay circuit D2 that delays the output Q by a delay time longer than 1 (for example, 0.15 to 0.3 seconds), the signals (5) and (6) are obtained. The return to the basic position (no-energization position) of each plunger PG1, PG2 of each solenoid is instantaneously returned when the energization is turned off by a spring (not shown).

Two such electromagnetic actuators (solenoids) are arranged as shown in FIG. 6D, and one end of the seesaw bar BAR is driven using the plungers PG1 and PG2. A gap GP1 (for example, 1 to 3 mm) is provided between the tip of the plunger PG1 that is driven first and the contact portion of the bar BAR, and the bar BAR is driven so as to be hit with a hammer. One end of the link member LK is pivotally connected to the other end BH via the rotation fulcrum PT of the bar BAR, and the other end of the link member LK is connected to the drive piece KL having the same function as K1 in FIG. A key lock is rotatably connected to one end KH, and when the bar BAR is rotated, the drive piece KL is driven horizontally via the link member LK. That is, when the sensor detects an abnormality, Tr1 is turned on, and at that timing, the lower part of BAR is pushed by the solenoid plunger, and the drive piece KL is pulled to the left by the upper part via the link member LK. Then, the driving piece K2 is pulled out from the vertical rib 6Y1 penetration term h5 of the column 6Y and the protrusion 3d9 or the hole h2 of the protrusion 3dp in the left direction of the drawing (see FIGS. 15, 16, 17, 19, 20, and 25). The BAR is hit with the first plunger PG1 as if it were pulled with a hammer.

At this time, even if the driving piece K2 is difficult to move due to dust, dust, rust, etc., the driving piece K2 is made easy to move by the tapping operation because the gap GP1 is provided. Subsequently, the BAR is driven by the second plunger PG2 at a timing (after D1) slightly delayed. When the driving piece K2 is pulled out from the hole h2, the projections 3d9 and 3dp are automatically detached from the hole h1 due to a decrease in potential energy due to the weight of the panel 10, and resist (conquer) the friction between the wheel 16 and the installation surface 92. The contact surface slides and the stop portion STP of the stopper ST moves to the outside of the rail portion and contacts the side surface 99 of the rail portion. Or depending on the case, the upper surface of the stock part STP abuts on the rail side projecting part 90. Thereby, even if an (external) force is applied to the panel, the vertical and horizontal movement of the panel 10 can be made as immobile as possible. When the electromagnetic actuator SL5 of FIG. 22 is used, it can be explained by the idea that the SL1 substitutes for the SL5. In this case, D1, AMP2, X2, SL2, PG2, and (d) FIG. However, when the above-described electromagnetic actuator SL7 is provided in the stabilizing plate portion REG and is also operated, it can be explained by the idea that the corresponding SL2 substitutes for SL7. In this case, the delay time D1 needs to be set to a value that is slightly larger than the delay time, that is, a value that is equal to or longer than the panel collapse time (for example, 800 ms or more). Furthermore, when the circuit for driving the relay X2 is made to correspond to SL7, X2 needs to be a self-holding circuit. The circuit shown in FIG. 6 (f) in consideration of this point is indicated by X7 instead of the relay X2, SX7 instead of the contact SX2, SL7 instead of the solenoid SL2, and the amplifier 2 and the relay X7. A diode Di6 is connected between the power source V and the relay X7, and a series circuit of the reset switch RSW, the contact X7S of the self-holding relay X7 and the diode Di5 is inserted and connected. That is, the panel collapsed by the plunger PG1 (corresponding to PG5) of the first solenoid SL1 (corresponding to SL5) by the circuit system in which the circuit diagram (C) and AMP2 and subsequent parts in the circuit diagram are replaced with the circuit diagram (f). Thus, immediately after the panel collapses, the panel bulge can be prevented by the plunger PG2 (corresponding to PG7) of the second solenoid SL2 (corresponding to SL7). This is because the relay X7 is driven by a one-shot pulse like the signal (6) in FIG. 25 (e), but is held by the contact X7S, so the plunger PG7 is turned on until the reset switch RSW is turned off all the time after the one-shot, This keeps it locked to prevent panel jumping.

By the way, the situation where the panel 10 is detached from the ground plane 92 does not occur frequently, but is an extremely infrequent event, for example, once every three years or once in the life of the apparatus. For example, the panel lock function must be fulfilled even after 10 years of installation. Therefore, a number of safety measures are taken in FIG. For example, the SW7 is a test switch that is turned on during operation check, and is operated when the electromagnetic actuator is driven to test whether the plunger (driving piece) can be removed from the hole. is there. Further, in order to increase the execution probability of the panel lock function, a plurality of pulse signal forming means (circuit) PLS added by a dotted line may be provided at a stage after the Q output of the FF780. This circuit PLS outputs a plurality of pulse waveforms as shown in (e) and (8), (9) of FIG. As a condition, it is activated by a rising signal “1” after a long “0” level input (for example, “0” level maintenance for 1 minute or more), “1” is 50 ms, then “0” is 150 ms, and A circuit in which “1” is repeated in the same manner as described above and the pulse is repeated 3 to 10 times is provided at the position shown in the figure. When the key lock K2 is disengaged from the predetermined position, it may be detected that the disengagement is detected and the subsequent pulses of PLS1 and PLS2 may be stopped. When PLS is added, the delay time of D2 is set longer than the sum of a plurality of pulses. When such a means is additionally inserted, the free end of the bar BAR is struck 6 to 20 times in total by the two plungers PG1 and PG2. Therefore, even if a non-attachment is attached around the key lock K2, the key lock is released with a very high probability.

The sum of the number of hits to the bar BAR and the hitting time is better as the number of hits is larger and the time is shorter. For example, 10 seconds per second seems to be appropriate for making an inexpensive system that does not depend on a special design, and further as a panel lock system before a major destruction of a panel or a building. Because, in this system, first, the upper surface of the stop portion STP approaches the direction in which it contacts the lower surface of the overhang portion 901 due to an enlargement phenomenon of the gap GP at the time of abnormality. When the vertical shaking such as an earthquake is large, the upper surface comes into contact with the lower surface and then swings back to lower the panel. It is better to remove the key lock within this time (preferably this one reciprocating motion). A system that allows this reciprocating motion a plurality of times increases the probability that the overhang portion 901 or the stop portion STP will break. Therefore, a quick response system is preferable. In terms of design, it is desirable that the key lock be released only once with the plunger PG1 at the time of product shipment. It is better to use such a mechanism (for example, providing the means of roller bearings R51 to R54 in FIG. 20) and / or a powerful solenoid. After the abnormal situation is settled, for example, in FIG. 19, the lever 3d4 is raised vertically to return the panel 10 to the normal state and return the BAR to the original state, thereby returning to the normal use state.

<Solar energy beneficiary drive system>
FIG. 26 is a block diagram showing an example of a solar energy beneficiary drive system driven under a protection program in consideration of safety, and FIG. 27 shows an example of the program, which is a normal solar tracking system. And a panel lock system that locks solar panels by receiving earthquake information from earthquake information distribution centers such as the Japan Meteorological Agency during large earthquakes. FIGS. 26 and 27 are drawn with a system centered on a personal computer (also referred to as a microcomputer) viewed from a general household where a solar panel is installed, and is also an embodiment of the present invention. In FIG. 26, a portion surrounded by a one-dot chain line represents a system that is substantially equivalent to FIGS. 23 and 25 (c), and different points will be apparent after this description.

The microcomputer and its peripheral circuits are connected to a microcomputer 252 to which a read only memory ROM, a random access memory RAM, and a central processing unit CPU are connected by a bus 250, a setting data input unit 251 connected to the bus 250, and the Internet. The connection terminal 253 is connected. Further, an earthquake information receiving device 254 is connected to the bus 250 as an input device. Further, as an output device from the bus 250, the solar panel azimuth movement control motor M1, the solar panel inclination movement control motor M2, and the panel locking solenoids SL1 and SL2 are connected to each other through drivers (or interface circuits) DR1, DR2 and DR3. Has been. Reference numeral 256 denotes a motor and its peripheral circuits. A panel azimuth movement propulsion unit including the relay RX in the forward step control circuit 763 and the relay LX in the reverse step control circuit 764 shown in FIG. Represents. Reference numeral 258 denotes a panel inclination angle moving propulsion unit having the same configuration as 256 in terms of circuit configuration.

In this system, an earthquake information acquisition means EQI whose transmission source is the Japan Meteorological Agency is connected to the connection terminal 253 via an external network (Internet 403). The EQI includes, for example, an earthquake observation network seismometer information source collected by seismometers installed all over Japan, a communication network 400 to the Japan Meteorological Agency, and earthquake information from the earthquake information source is collected via the communication network. It includes an apparatus 410 in an earthquake information distribution center 401 such as the Japan Meteorological Agency, and an Internet system 403 that distributes an earthquake early warning 405 transmitted from the apparatus 410 in the center over the Internet. The device 410 may be installed at one location of the Japan Meteorological Agency, but requires a system or device that converts and distributes data so that it can be easily used by devices that use this earthquake information. Such a device is installed in the Japan Meteorological Agency, or the real-time earthquake information utilization conference device 402 shown in FIG. Since the device 410 is a system, it may include a center 401. When an earthquake actually occurs by the above information network, earthquake information from all over the country is collected, the epicenter and its magnitude (magnitude) are instantaneously determined, and the emergency earthquake bulletin 405 is distributed from the device 402 to the Internet. This information includes voice guidance information of earthquake information, for example, voice including “Sind, Rok, Jak”, “Sind, Go, Kyo” and the like. The earthquake information receiving device 254 includes an Internet terminal and directly receives the earthquake early warning or is connected to a bus of a terminal computer installed in the home and indirectly connected to an Internet terminal (for example, a USB terminal). Receive. Upon reception, the device 254 emits voice guidance saying “A, Sind, Go, Kyo, B”, for example. The part A may be, for example, “Kinkyu Shin Sokuhou” or “Dishin Hassei”. The part B may be additional explanatory text. This voice guidance is analyzed by the CPU and the panel is locked when there is a large earthquake.

The flow of solar panel movement control will be described in order using FIG. FIG. 27A is a main routine of a computer program in a home or facility where a solar panel is installed, and FIG. 27B is a timer interrupt routine processed by a timer interrupt every minute or every second. Yes, (c) is a routine on the seismic information transmission side of EQI such as the Japan Meteorological Agency, and (d) is a detailed routine of the processing 70 of (a). In FIG. 27A, when the main routine is started by turning on the power in S10, each flag, each data (for example, m1, m2, mode, timer, various initial condition data such as latitude for solar position calculation, etc.) ) Is initially set. In the next step S12, a change setting (manual change) of the sunset / sunrise time is accepted. Once the setting is changed, there is almost no change, and in the process at the time of return from the final process S70, the through process is common. In the next step S13, a branch / judgment process for the sunset / sunrise mode is performed.

Hereinafter, the description will be continued as processing from sunrise. Assuming that the sunset mode (mode defining from sunset to sunrise) has been presented in S13, branch processing is performed to determine whether or not it is a sunrise time in S14. It is determined “no” until dawn, and the process goes through S70 and returns to S12, and repeats S13 and S14. S70 is a panel safety process, which will be described later, and is a rare process of whether to work 0 to several times during the life of the apparatus, and is usually almost a through process. If the time before dawn is reached, it is determined in S14 that the sunrise time is reached. In S15, the sunrise mode (mode for defining from sunrise to sunset) SR is set, and in the flow S13 after the return, the process is branched to SR. Whether or not the motors M1 and M2 are being driven (m1 or m2 is 1) is branched to determine “NO”. That is, the SR time is set at or slightly before the sunrise time, and the panel starts moving from the first n hours after the sunrise (n varies depending on the season), so the motor has not started yet at this time. . The motor flag is determined to be “yes” when one of the flag m1 of the panel azimuth angle control motor M1 and the flag m2 of the panel tilt angle control motor M2 is “1”, and the process jumps to S20. If “NO” is determined in S16, a branching process is performed to determine whether it is the sunset time in S17, and a determination is made in S18 that whether it is just at the predetermined time n is determined in S18. S12, S13, S17, and S18 are repeated with a “no” determination until the n-hour just time. When the n hour just time is reached, the motors M1 and M2 are driven aiming at the target values A and B at the n hour in S19. The motor drive flags m1 and m2 are set to “1”. The target values A and B are calculated in advance in the solar orbit calculation process S42. That is, according to FIG. 27B, the target value of the panel to be moved next is calculated one minute before the time to move in S40, S41, and S42.

When this process is started in S40 at the timer interrupt, the branching process is performed in S41 for one minute before the predetermined time n in the SR mode. At the timing of one minute, the solar orbit calculation process and The optimum position in the panel facing direction is calculated based on, and the values are stored in the A and B registers, and the process returns in S43. The A value of A is a panel angle Aa that is ideally perpendicular to (directly facing) the solar altitude, except for the panel angle Ab when the solar altitude is quite high and the panel angle Ac when it is very low. In the special state Ab or Ac, a value rounded to the limit value, for example, a predetermined value of Ab = 15 degrees and Ac = 45 to 50 degrees is set. The B value of B is the panel azimuth angle Ba that is ideally perpendicular to the solar azimuth angle (directly opposite), and is equal to Ba in the autumn / winter spring when the sun is out in a narrow range. At a time near sunrise or sunset in autumn, the true value Bb and the true west value Bc may be used as limit values.

When the motors M1 and M2 start to move in S19, in a next step S20, it is branched whether or not the target value of the motor M2 is the A value, and the “no” determination is repeated until the motor M2 reaches the A value. Keeps moving. That is, whether or not the target value B of the motor M1 is determined in S21 by “No” in S20, and whether or not there is a motor abnormality is determined in “No” determination in S22 and S23 and both are determined as “No”. It is determined that there is no abnormality and the process returns. If an abnormality is found in the motors M1 and M2 at this time, it is determined as “yes” in the overcurrent determination of each motor M1 and M2 in S22, and the flag m1 and / or m2 is set to “0” in S26 and there is an abnormality. The motor is stopped and a failure is displayed in S27. Further, it is determined in S23 that the time that the panel should reach has not been reached (for example, gear pin breakage) although the motors M1 and M2 are moving, and the motor M1 and / or the motor M1 and / or S2 in S26. Alternatively, M2 is stopped. If “yes” is determined in S21, m1, m2, B, and A are set to “0”, and both the motors M1 and M2 are stopped. The reason for this is as described above.

As long as there is no motor abnormality as described above, S12, S13, S17, S18, S19, S20, S21, S22, and S23 are executed during the repetition of S12, S13, S17, and S18, and the panel target value at that time ( Each motor is driven until it reaches the position), and when it reaches the target value, it is stopped a predetermined number of times until sunset. When it is sunset (or any time thereafter), branch determination is made to “yes” in S17, the mode is changed from SR to SS in S28, and A and B values at the sunrise time of the next day are calculated in S29. Aiming at the A and B values, the motors M1 and M2 are reversely driven. The flags are m1 = 1 and m2 = 1 indicating the movement. When the panel moves back to the east in the sunrise direction, the motors are stopped in S20, S25, S21, and S24, the flags are returned to “0”, and the loops of S12, S13, and S14 are formed. The panel drive is paused until the next day's sunrise. It is a system that repeats this throughout the year.

When an earthquake early warning is issued by the Japan Meteorological Agency, etc. at an arbitrary timing during panel drive suspension in sunset mode SS or during sunrise mode SR, that is, during intermittent panel movement (including suspension) throughout the year The earthquake early warning is output from the means EQI. At this time, whether or not the early warning information is large enough to lock the panel is checked by the judging means on the transmitting side and the receiving side. For example, since the above earthquake early warning is information that is desired regardless of its severity, it is assumed that it is issued regardless of the magnitude of the earthquake, and information with a seismic intensity of less than 5 is also issued. Send with. In general, earthquake information is emitted from the Japan Meteorological Agency when an ordinary or greater earthquake occurs, but if the earthquake is greater than a predetermined earthquake, the transmission mode is activated in S50, and it is determined whether or not the information is an emergency earthquake warning in S51. If it is determined to be a preliminary report, an “emergency earthquake preliminary report” is issued in S 52, and the signal is widely transmitted to the general public via the Internet line and can be received by the earthquake information receiver 254 on the receiving side.

The device 254 provides voice guidance for “A, Sind, Go, Kyo, B” and the like. Accordingly, in FIG. 27D, when the apparatus 254 is activated, it is determined whether or not the earthquake information is voice-announced in S61. If yes, the information is determined in the voice guidance voice recognition flow S62 in the CPU. Voice recognition is performed, and in S63, it is determined whether a plurality of keywords “Sind”, “Number Go”, and “Kyo / Jac” are all included and arranged in the above order. In addition, “For training” or “Test” ”Or“ examination ”, it detects that there are no virtual keywords (non-practical words) in front of the important voice guidance. If “YES” is determined in S63, a safety instruction signal SAF for locking the panel is generated in S64, and the solenoids SL1, SL2, or SL5 (FIG. 22) shown in FIG. 25 are turned on by the instruction signal SAF. To drive. If “NO” in S61 or S63, the process returns in S65 and no safety signal is generated. Thus, when an emergency earthquake warning is issued when an earthquake occurs, the solenoids SL1, SL2, and SL5 are driven using the warning as a command signal, and the drive piece KL or PG1 is pulled out and driven, for example, in the state indicated by the dotted line in FIG. The solar panel can be locked.

Note that the earthquake information receiving device 254 has a function unit that directly senses an alarm signal of seismic intensity of 5 or higher issued from the Meteorological Agency or the real-time earthquake information utilization council device 302 and emits a “1” signal at the time of detection. For example, the solenoids SL1 and SL2 may be driven by a direct drive signal. In this case, the computer program control is unnecessary, and the above panel lock safety function can be enjoyed by connecting to the input terminal SAF in the electronic circuit system FIG.

As described above, although a number of embodiments according to the present invention have been described, the solar panel rotating body shaft rotation joint portion includes the shaft portion movement allowance portion, and the shaft portion movement allowance portion is configured such that the panel rotation body is rotated by azimuth displacement. A lock mechanism that is locked at the position where the shaft portion movement allowance portion is set, and by detaching the lock portion of the lock mechanism, a reduction in the potential energy of the panel rotating body is promoted, and a predetermined amount of the potential energy is consumed. By doing so, the panel rotating body moves vertically and horizontally, and the horizontal movement allows the stopper portion STP to abut on the stepped portion to make the panel rotating body immobile. (Gravity utilizing stopper mechanism and locking mechanism). This makes it possible to instantly cause a state displacement by simply removing the lock mechanism using the law of gravity drop using the potential energy of the panel rotating body.

Further, the lock mechanism includes a lock portion, a lock holding portion, and an auto-lock release mechanism, and the auto-lock release mechanism is unlocked by a lock release command signal (output of FF780). The solar energy beneficiary device (gravity utilizing stopper mechanism and auto-lock releasing mechanism) configured to move the lock portion from the lock holding portion to release the lock when it arrives. Thus, the lock can be automatically released, so that the state displacement can be instantly generated, and the panel rotating body can be temporarily fixed to the installation surface quickly when an abnormal situation is predicted.

Further, the stopper mechanism for holding the panel may be brought into contact with a contact portion provided on the installation surface by simply laying down the panel. That is, the stopper mechanism may be constituted by a horizontal movement blocking portion (receiving side) and a stopper (contacting side).

Furthermore, in FIG. 14, a solar cell panel (power generation body using sunlight) indicated by a dotted line may be provided below the panel 110. This solar cell is used for various applications. For example, the electrical system may be supported as an emergency power generator. For example, when a strong wind increases at the time of a power failure during a typhoon and the panel is about to be blown, it can be used as a power source for driving the electromagnetic actuator. At all times, it may be used as an auxiliary power source for use in a general household, for example.

In addition, the solar panel of the present invention is generally used while being mounted on a pedestal frame, but the panel itself may also serve as the pedestal frame. The solar panel rotating body in this case is the panel itself. Moreover, although the upper part and the lower part are integrally provided in the embodiment in the solar panel rotating body of the present invention, they may be provided separately on the upper and lower sides, and may be configured integrally with the pedestal frame. When the panel is divided into upper and lower parts, for example, the panel may be formed with an angle in the vertical and horizontal directions according to the shape of the building 8 in FIG.

Further, in the present invention, as shown in FIGS. 9, 14, 15, 18, and 19, the support position of the panel or the panel rotating body is half of its full length (oblique vertical length) with respect to the two upper and lower positions (span) ( It is preferable that the upper support position is equal to or less than 1/3 of the total length from the upper end of the panel (DS2) and the lower support position is equal to or less than 1/3 of the total length from the lower end of the panel (DS3). This is because the more deviating from the above conditions, the more unstable the panel support becomes. However, the above conditions assume a flat panel with a uniform cross section. The above conditions should be set in consideration of the center of gravity when the center of gravity of the panel is changed. In this case, for example, DS1 = 1/3 or more and DS2 = DS3 = 4/10 or less. It may be possible to manufacture. For example, the total length of the panel is 1 m, the panel upper supported part (for example, the lower end 11bb of the other end 1b of the frame 11) is the upper end of the panel (0 cm from the upper end), and the panel lower supported part (the panel corresponding to the legs 12, 13). If the part portion is 40 cm from the bottom of the panel and the elevation angle i = 45 degrees, the radius of the rail portion is 60 × 0.707 = 42.4 cm, which is less than half of the total length. As described above, the rail member used in the present invention can be constructed without increasing the size compared to the conventional case where the center of rotation is at the center of the panel.

In addition, the stopper means (ST or STP call 901) at the time of panel collapse provided near the movement support means (wheel) in the lower part of the panel rotating body has a collar projecting from the panel rotating body (moving body) side. The rails 90 are brought into contact with the side surface, and the vertical movement is prohibited by the undercut portion 901 so as to minimize the damage in an emergency. However, in the configuration shown in FIG. The occurrence probability may be lowered. In other words, it should not be blown by strong winds as it is laid down, and even if it is broken by an earthquake, the potential energy is kept low, so there should be less disaster. Therefore, in this embodiment, “panel laying” corresponds to the concept of “panel collapse”. In that case, in order to further reduce the probability of occurrence of danger, a stopper body (not shown) provided in the vicinity of the movement support means is brought into contact with a contact body slightly raised from the installation surface when the panel is laid down. You may make it say that it prepares for an emergency. Therefore, in this embodiment, “panel laying” corresponds to the concept of “panel collapse”.

  The “movement support means” and “driving means” in the claims can be called “movement means”. The “movement support means” may be wheels, sliding shoes, two legs, or a three-legged walking body.

In addition, according to the method described with reference to FIG. 23, the sun tracking control method of the present invention performs hybrid control of intermittent timer control and light tracking by an optical sensor. Is effective only when panel azimuth driving is performed intermittently. This reduces the probability of malfunction due to ambiguity control of the optical sensor. In other words, in order to eliminate all disturbances with the optical sensor and to control it, a number of guarantee means and compensation means are required, but the elevation angle control can be added to the azimuth angle control by adding a simple optical sensor. .

In the control circuit shown in FIG. 25, when a plurality of pulses are generated from the PLS, one pulse is composed of a large number of fine pulses, and the duty ratio of the fine many pulses is changed from the first pulse to the second and third pulses. If the effective portion is increased as the number of times is increased, it becomes easier to remove the ridge (KL) of the ridge structure.
In addition, each constituent element corresponding symbol and number in the specification is an exemplification, and each element corresponds to all corresponding part elements as a result of considering the specification and drawings. For example, as shown in a number of embodiments, the shaft rotary joint portion exists from a simple configuration to a composite configuration (from a narrow sense to a broad sense).
