Description

ちなみに入射光と反射光と集光点を平面内に収めるといっても、幾何学上の厳密な平面や点ではない。鏡に平面鏡を用いるならば、反射光の集束する所もおよそ鏡の幅をもつ集束域となる。 The present invention relates to a solar collector that reflects and collects sunlight with a plurality of mirrors. Or heliostat. More specifically, it is a two-axis tracking type, point condensing system concentrator.
The mirror here refers to all objects that reflect sunlight, sunlight, and sunlight. The mirror includes a reflector, a plane mirror, a concave mirror, a parabolic mirror, and a polygon mirror.
The usage forms of the concentrator are a generator, a Stirling engine prime mover, an air conditioner, a distiller, a hot water hot water supply device, a cooking device, and the like.
Please refer to Table 1 when reading the specification. The gist of the present invention is simple. The incident light, the reflected light, and the condensing point are within a plane. However, there are many different embodiments. In order to cover these various configurations, the member names in the claims are expressed by a superordinate concept. The member in an Example is described with the subordinate concept. Moreover, the form in which one member serves as two structural requirements can also be comprised. Therefore, a comparison table of member names having different notations in the claims and the examples is shown.

By the way, even if incident light, reflected light, and a condensing point are contained in a plane, it is not a strict geometric plane or point. If a plane mirror is used as the mirror, the spot where the reflected light is focused also becomes a focusing area having a mirror width.

In order to collect sunlight by reflecting it with a mirror, it is necessary to track the sun and control the angle of the mirror. There are many tracking methods. The single axis tracking method requires a simple device. However, with single-axis tracking, the focusing area of reflected light is dispersed, and the light collection rate decreases. In the biaxial tracking method, the reflected light converges to one point and the light collection rate increases. However, the two-axis tracking requires a tracking device for each mirror and is expensive. Therefore, it has been a problem to track a large number of mirrors in two axes with a simple mechanical mechanism. Several prior applications for this subject were filed. However, these patent documents contained errors and problems.
The error of the prior application is that it is established only with a mirror at a specific position on a specific day, but no other light is collected. A condensing tower is built, and mirrors are arranged in a row in the east-west direction from the position where this condensing point casts a shadow on Equinox, and a mechanism for collectively operating these mirrors is constructed. This concentrator is not established except for the equinox and for the equinox, and is not always established for a mirror whose positional relationship with the concentrator is shifted. All of Patent Documents 1 to 3 are errors that apply to all.
The problem with the prior application is that there is a problem with thermal expansion. Since the condenser is installed outdoors, it is affected by the outside air temperature. The object expands and contracts due to heat. The longer it is, the more affected by thermal expansion. Each of Patent Documents 1 to 3 includes a long member and has a configuration in which the adverse effects of thermal expansion cannot be avoided.

  An object of the present invention is to collectively control the two-axis tracking of a large number of mirrors with a simple mechanical mechanism. In other words, the number of driving devices is much smaller than the number of mirrors. In addition, when a condenser is constructed in a large size, it needs to be considered for thermal expansion because it is affected by thermal expansion.

  If the posture of a large number of mirrors is controlled with a simple mechanical mechanism, it is advantageous to arrange the mirrors in a straight line. A collective operation method using a simple mechanical mechanism can be established only when the condition that all the optical paths are in the same plane is satisfied. The only way to satisfy these conditions is to move the condensing area according to the tracking. Therefore, it is the gist of the solution means to keep the condensing area on a plane including the sun and mirror rows. At the cost of moving the condensing area, which has been fixed in the past, it has gained the benefit of realizing two-axis tracking with a simple mechanical mechanism.

A specific solution is to arrange a plurality of mirrors along the X coordinate axis on the XY coordinate plane of the XYZ orthogonal coordinates to form a mirror support member having a length in contact with all the mirrors, and each mirror rotates in the Y direction. connected to the Y bearing mechanism via a mirror support member, connecting the strut to the mirror supporting member through the X bearing mechanism and the axis of the X coordinate axis, the X axis to an arbitrary position of the mirror support member axes the X-axis angle transmission member to mind fixed connection, assuming a condensing zone at any position in the Z-axis line, the condenser region of the photothermal utilization means is located, the photothermal utilization means a mirror supported by a rod It is fixedly connected to the member , all mirrors are set to the initial Y-axis angle so that the assumed sunlight is reflected to the light heat utilization means, and the Y-axis crank is used for the members that rotate the Y-axis of all mirrors. Are fixedly connected, and all Y-axis cranks are connected to the Y-axis cranks at equal angles. An interlocking mechanism is connected to the shaft, and this crank interlocking mechanism is connected to a Y-axis angle control means for controlling the Y-axis angle of the mirror by crank motion. It is fixed to the collector installation plane, and one or more of these units are arranged in parallel. The X-axis angle transmission members of all units are connected to the X-axis angle control means, and the X-axis angle control means and the Y-axis angle control means The solution is to configure a solar concentrator that tracks the sun.
In addition, consideration for thermal expansion is necessary to increase the size of the condenser. Larger scale is just one of the design elements, but when it comes to outdoor structures in optical systems, it is essential to deal with thermal expansion. To cope with the thermal expansion, a connection configuration that allows a displacement amount that expands and contracts due to the thermal expansion is adopted.

The XYZ orthogonal coordinates here are expressions for facilitating understanding of the configuration of the main part of the present invention. The main part is movable by operating the device. The Y-coordinate axis and the Z-coordinate axis are not fixed and move by operation.
The mirror support member here is a member that holds the mirror. The mirror support member may be a frame surrounding the entire circumference of the mirror or a frame along one side of the mirror. This is the same as the relationship between the spectacle lens and the spectacle frame. As an example other than the embodiment, please also refer to Patent Document 3.
Here, the reason why the X bearing mechanism and the Y bearing mechanism are referred to as a bearing mechanism is that the positional relationship between the shaft rod and the bearing is established even in the reverse direction. This is because either the fixed side or the movable side can be a shaft rod and either can be a bearing.
Here, a Y bearing and a mirror reinforcing member can also be configured as a technically equivalent configuration for connecting the back surface of the mirror and the Y-axis angle crank.

The X axis angle transmission member and the X axis angle control means will be described. The X-axis angle transmission member is a member that transmits rotation to the X-axis bar. Specific X-axis angle transmission members and connection members are listed as sprockets and chains, gear gears and gear connection mechanisms, pulleys and belts, cranks and crank connection members, and the like. The frame angle transmission member is connected to the frame angle control means by a connecting member, and is driven by an appropriate power source. The power source is an electric motor, a linear motor, a hydraulic cylinder, or the like. Or the structure which operates the crank which rotates with an X-axis by human power is also materialized.
A condensing area here is an area targeted at the design stage to collect light as a solar concentrator. The area where the reflected light from the mirror is eventually focused is referred to as the focusing area.
The light heat utilization means includes solar thermal power generation, solar thermal power machine, solar distiller, hot water feeder, cooker, illuminator, and the like. Or it is a circulation path of the heat medium for transferring heat to these light heat utilization means.
The crank interlocking mechanism here is a mechanism for interlocking many Y-axis cranks. The Y-axis cranks are arranged in parallel and in series. Therefore, if the other end of the Y-axis crank is connected by a linear member, all the Y-axis cranks can be linked. The crank interlocking mechanism only needs to rotate the Y axis by an equal angle in the crank motion. Therefore, the shape and direction of the Y-axis crank can be variously configured. See Patent Document 3 for a specific example.

The diameter difference eliminating crank referred to here is a crank that eliminates a difference in distance between the crank interlocking mechanism and the X axis. When the crank interlock mechanism is cranked, the radial distance from the X axis center to the east end of the crank interlock mechanism changes. Therefore, a diameter difference eliminating crank is interposed between the X axis and the east end of the crank interlocking mechanism.
Here, the control of the X-axis angle control means and the Y-axis angle control means is a biaxial sun tracking means. Where appropriate, conventional techniques of solar tracking are used. For example, a calendar control method in which data converted from the azimuth and elevation angle of the solar orbit coordinates to the X-axis angle and the Y-axis angle is stored in a computer and controlled according to the date and time. If we incorporate the age of the moon, it becomes more accurate. Feedback control by a sensor may be used.
The meaning of fixing the column to the collector installation plane here means that the installation direction of the collector is not limited. If there are no geographical restrictions, the east-west unit is the best. The reason is the light collection efficiency and the ease of tracking. As long as it is flat, both slopes and vertical surfaces can be installed. In the case of wall installation, a vertical wall is preferred. The reason is that even if the X-axis angle is manipulated, there is no difference in height of the condensing part, and the force required for the X-axis angle control is constant.
Arranging one or more units in parallel here means adding units in parallel next to each other. It also means that it includes a single unit configuration. Even a single unit is sufficiently effective as a condenser.

The effect of the present invention is that two-axis tracking of a large number of mirrors is realized by a simple mechanical mechanism. Conventionally, in order to track a large number of mirrors in two axes, each mirror requires a driving device, sensors, piping, and wiring for tracking in two axes. In the present invention, only one set or several sets of drive devices are required in the entire concentrator. Even if the estimation is made with 30 mirrors, the reduction effect of this driving device is great.
Another effect is that it is easy to perform maintenance and storm evacuation of the means for utilizing light heat. In the tower type concentrator, the trouble of maintaining the light heat utilization means at the top of the tower is a burden. In the present invention, the operation such as maintenance is facilitated by operating the light heat utilization means to a low position. Even when storms such as typhoons are forecasted by weather, damage can be avoided by lowering the light heat utilization means. Moreover, the structure of Claims 4 and 5 prevents the harmful effects of thermal expansion.

FIG. 3 is an overall perspective view of the second embodiment. FIG. 4 is a side view of the periphery of the mirror according to the second embodiment. FIG. 5 is a side view of the peripheral portion of the mirror according to the second embodiment, in which the mirror is tilted.

The concentrator can be used for various purposes. There are many design elements for concentrators. Therefore, there are a wide variety of concentrator embodiments. Although only basic examples can be introduced, it should be understood that the examples are very diverse. In particular, mirrors and units have a lot of room for expansion. 30 units can be constituted by 30 mirrors. When such a large-scale concentrator is constructed, consideration for thermal expansion becomes necessary. Since it is difficult to illustrate, in the embodiment, three mirrors and three units are used. Even if it is a 3rd mirror, please see that thermal expansion displacement equivalent to the 30th mirror occurs.
Corresponding member names differ between the claims and the embodiments. The comparison is shown in Table 1, so please refer to it.

The first embodiment corresponds to claims 1 and 4. A description will be given with reference to FIGS. FIG. 2 omits the north mirror. Only the mirror at the northeastern end is shown with an imaginary line. The northwest end portion also omits the Y bearing 6 and the Y-axis crank 7. The X-axis rod 2 faces east and west, and the four X bearings 3 are engaged. A column 4 is connected to the X bearing 3, and the column 4 is fixed to the ground. Three Y-axis rods 5 are fixed to the X-axis rod 2 in the north-south direction. A Y bearing 6 is engaged with the Y axis rod 5. The mirror 1 is connected to the Y bearing 6. A Y-axis crank 7 is fixedly connected to the Y bearing 6. A crank interlocking mechanism 9 comprising three horizontal bars 8 that are in contact with two long bars at right angles is formed. The crank interlocking mechanism 9 is positioned directly under the mirror 1 row. The lower end of the Y-axis crank 7 is axially connected to the crank interlocking mechanism 9. The horizontal bar 8 also serves as a shaft bar connected to the lower end of the Y-axis crank 7. At this time, all the Y-axis cranks 7 are in the same direction and posture, but each mirror 1 is in the posture of the initial Y-axis angle.
The east end of the crank interlocking mechanism 9 is axially connected to a diameter difference eliminating crank 10. The diameter difference canceling crank 10 is symmetrical, and the other end is connected to the east end of the crank interlocking mechanism 9 on the south side. The east end of the diameter difference eliminating crank 10 is rotatably engaged with the sliding tube 11. The sliding tube 11 is engaged with the X-axis bar 2. The sliding tube 11 is connected to the piston of the Y-axis control cylinder 12. The Y-axis control cylinder 12 is fixedly connected to the X-axis rod 2 by a fixture 13.

The west end of the X-axis bar 2 is fixedly connected in the shape of an F-shape by making two ridges 14 orthogonal. The light collecting unit support 15 is engaged with the X-axis rod 2 between the reeds 14 and 14, and the light collecting unit support 15 is fixed to the ground. The light heat utilization means 16 is fixedly connected to the upper end of the flange 14. A shaft rod 17 is fixedly connected to the upper portion of the shaft 14. The shaft rod 17 is connected to the piston of the X-axis control cylinder 18. The lower end of the X-axis control cylinder 18 is axially connected to the ground.
The tracking control will be described. The angle of 竿 14 is adjusted to the elevation angle of the sun based on the X axis. This is done by extending and contracting the X-axis control cylinder 18. Next, the Y-axis angle of the mirror 1 is manipulated so that the reflected light converges the focusing area. This is done by extending and contracting the Y-axis control cylinder 12. When the X-axis control cylinder 18 is contracted from the state shown in FIG. 2, the X-axis bar 2 rotates as shown in FIG. 1, and the mirror 1 is tilted northward. When the Y-axis control cylinder 12 is extended from the state shown in FIG. 1, the Y bearing 6 rotates as shown in FIG.
The condensing unit support 15 that engages with the X-axis rod 2 is a non-slidable bearing mechanism. Therefore, even if the X-axis rod 2 expands and contracts due to thermal expansion, only the X bearing 3 and the X-axis rod 2 slide, and there is no problem. The east end is made extra long so that it does not fall off even if the X-axis rod 2 shrinks. Although the space between the Y-axis rods 5 expands and contracts due to thermal expansion, the crank interlocking mechanism 9 also expands and contracts equally, so there is no problem. Although the long X-axis control cylinder 18 is illustrated, it is for making the configuration easy to see. In practice, a configuration may be used in which a short cylinder is connected from the vicinity of the base of the rod 14 like an arm drive cylinder of a crane truck.

The second embodiment corresponds to claims 2, 4 and 5. This will be described with reference to FIGS. The feature of the second embodiment is that the mirror support member , the unit pluralization, and the light collecting unit are separately controlled. Three mirrors 20 are arranged in the east-west direction. An east-west bar 21 facing all mirrors 20 is located on the south side and the north side. This east-west bar 21 is connected by a north-south-facing Y-axis bar 22 to form a ladder-shaped seesaw frame 23. A support column 25 is connected to the central lower part of all Y-axis rods 22 via an X bearing mechanism 24 having a common east-west straight line as an axis. All the columns 25 are fixed on the collector installation surface. Further, a Y bearing 26 is engaged with the Y axis rod 22, and the mirror 20 is connected to the Y bearing 26. An X-axis crank 27 is fixedly connected to the west end of the seesaw frame 23. 4 and 5 show the portions of the X bearing mechanism 24 and the Y axis rod 22 in detail. Since the X bearing 28 is shorter than the X axis rod 29, it can slide by the difference. A Y-axis rod 22 is fixedly connected on the X bearing 28. A Y-axis crank 31 is fixedly connected to the Y bearing 26. In FIG. 4, for easy understanding, the initial Y angle is assumed to be 0 degree, and the Y-axis crank 31 is vertically downward with respect to the mirror. The lower end of the Y-axis crank 31 is connected to the crank interlocking rod 32.
An adjacent shaft rod 33 is provided on the X axis extension beyond the east end of the seesaw frame 23. Both ends of the adjacent shaft rod 33 are fixedly supported by adjacent struts 34. A sliding bearing 35 is engaged with the adjacent shaft rod 33. The sliding bearing 35 is slidable along the adjacent shaft rod 33 and is rotatable about the adjacent shaft rod 33 as an axis. The center portion of the V-shaped diameter difference eliminating crank 36 is connected to the sliding bearing 35 as a shaft, and the other end of the diameter difference eliminating crank 36 is connected to the east end of the crank interlocking rod 32.

All the configurations described above are one unit. Two other units are arranged in parallel in this unit. There is a groove in the upper part of the sliding bearing 35 of each unit, and the unit interlocking rod 37 is slidably engaged. The unit interlocking rod 37 is engaged with the piston of the Y-axis control cylinder 38. The Y-axis control cylinder 38 is fixed by a gantry 40.
The X-axis cranks 27 between adjacent units are connected by a spring 41 made of an elastic material . On the outside of the X-axis crank 27 at the end, a counterbalance crank 42 is fixed by a support base 43. The balance crank 42 and the X-axis crank 27 are also connected by a spring 41. The north balancing crank 42 is axially connected to the motor 44. The spring tension of each part is set to be equal. In the X-axis crank 27, the tension between adjacent springs cancels out, so there is no spring tension load. The angle of the counter crank 42 is controlled by the rotation of the motor 44, and all the X axis cranks 27 are also interlocked so that the X axis angles of all the units can be collectively controlled. Since expansion and contraction due to thermal expansion is absorbed by the spring 41, no error occurs.
Next, with reference to FIGS. 6 to 8, the movable structure that drives and controls the light collecting unit will be described. 6 to 8 are views seen from the west. In order to make it easy to see, only the mirror 20, the support column 25 and the support base 43 are shown on the unit side, and the rest are omitted. Two gutter support bases 45 are provided on the ground below the light condensing area of the concentrator. A gutter 46 is axially connected to each gutter support base 45, and a beam 47 is axially connected to the upper end of the gutter 46. The light heat utilization means 48 is fixed at the position of the condensing area of the beam 47. Wires 50 are connected to both ends of the upper surface of the beam 47. A steel tower 51 is built outside the heel support 46. A pulley 52 is provided at the upper end of the steel tower 51. A winding pulley 53 and wire control means 54 are provided outside the base of the steel tower 51. The wire 50 connected to the beam 47 passes through the pulley 52 at the upper end of the steel tower 51 and is connected to the winding pulley 53.

The operation of the light collecting unit will be described. The attitude control of the mirror 20 and the attitude control of the light collecting unit are separate mechanical mechanisms, and the controls are also separate. The direction of the mirror 20 is controlled so as to receive sunlight vertically. At the same time, the rod 46 is controlled to the north inclined posture so that the photothermal utilization means 48 is positioned in the optical path of the reflected light of the mirror 20. This state is shown in FIG. The posture of the heel 46 is controlled by pulling the left and right wires 50. When the north wire 50 is loosened and the south wire 50 is pulled, the reed 46 is in a vertical posture as shown in FIG. When the wire 50 is further operated, the ridge 46 is inclined southward as shown in FIG.
The movable structure for driving and controlling the condensing unit of Example 2 is large and inefficient. However, when the number of units to be connected increases to 30, 50, an efficient configuration is obtained. The movable structure may be another method. For example, the beam may move vertically between two steel towers, and the light heat utilization means may move left and right along the beam. Since the unit part is held by a spring, resonance prevention measures are taken if necessary.

This corresponds to claims 1 and 3. Description will be made with reference to FIGS. This is an example in which the unit posture is vertical and the control drive is manual. A reference vertical line is assumed along the building wall 60 that is generally south-facing and vertical. A horizontal support 61 is fixedly connected so as to intersect with the reference vertical line. A short X-axis bar standing upright is fixedly connected to the upper surface of the tip of the column 61. A small thrust bearing 63 is engaged with the X-axis rod. The seesaw frame 65 is formed by connecting two parallel and vertical bars with three east and west bars 64, and the east and west bars 64 and the small thrust bearing 63 are engaged. The seesaw frame 65 is shaped like a two-square ladder. A cylindrical pedestal 66 having an axial center aligned with a reference vertical line is fixedly connected to the lower end of the seesaw frame 65, and a large thrust bearing 67 is engaged between the lower surface of the cylindrical pedestal 66 and the ground.
A Y-axis bar 68 is fixedly connected to a position half above the grid from the east-west bar 64 of the seesaw frame 65, and a mirror 71 is connected to the Y-axis bar 68 via a Y bearing 70. An elevation crank 72 is fixedly connected to the Y bearing 70, and the other end of the elevation crank 72 is axially connected to a crank interlocking rod 73. The adjacent X-axis rod 74 is positioned on the reference vertical line of the X-axis rod at the upper end, and the adjacent X-bearing 75 is engaged with the adjacent X-axis rod 74. The adjacent X bearing 75 is fixed to the building wall surface 60 by the adjacent support column 76. A connecting pipe 77 is fixedly connected to the lower end of the adjacent X-axis rod 74, a diameter difference eliminating crank 78 is axially connected to the connecting pipe 77, and the lower end of the diameter difference eliminating crank 78 is axially connected to the upper end of the crank interlocking rod 73. . The X axis rod, the small thrust bearing 63, the cylindrical pedestal 66, the large thrust bearing 67, the adjacent X axis rod 74, and the adjacent X bearing 75 are aligned with the reference vertical line.

The upper end of the adjacent X axis rod 74 is connected to the wire 80. The wire 80 is placed on a pulley 81 installed on the building wall 60. A counterweight 82 is suspended from the other end of the wire 80. The weight of the counterweight 82 is balanced with the crank interlocking rod 73 side. A string 83 is connected to the lower end of the counterweight 82. The string 83 is folded back at an appropriate height, hung on the pulley 81, and connected to the wire 80. When the string 83 is pulled, the wire 80 is pulled, the crank interlocking rod 73 is raised, and the mirror 71 is tilted forward. If the reverse side string 83 is pulled, the wire 80 is loosened, the crank interlocking rod 73 is lowered by its own weight, and the mirror 71 is inclined to the opposite side.
A beam 84 is connected to the cylindrical pedestal 66. A carriage 85 is connected to the tip of the beam 84. The direction of the wheel 86 of the carriage 85 is the direction orthogonal to the beam 84. A heating table 87 is provided on the carriage 85. A grip 88 is provided on the side surface of the heating table 87. The initial elevation angle of the mirror is set so that the heating table 87 is in the condensing region. Place the pan 90 on the heating table 87. The direction of sunlight and the beam 84 are matched. If the angle of the mirror 71 is operated with the string 83 so that the sunlight converging area comes to the heating table 87, it operates as a solar cooker. In the direction tracking, the carriage 85 is moved by the grip 88 so that the sunlight and the beam 84 coincide with each other. In elevation tracking, the angle of the mirror 71 is operated with the string 83.
Although three embodiments have been introduced above, the concentrator of the present invention can take other forms. In the embodiment, the number of mirrors is three for easy illustration, but the number of mirrors is actually increased in order to obtain a high temperature. In addition, in the configuration of the first embodiment, a configuration in which a mirror is also installed on the west side around the ridge is also conceivable.

  In the present invention, it is possible to set a plurality of light condensing areas in one unit. The initial Y-axis angle may be set so that the mirrors are grouped and focused on the respective focal coordinates for each group. The present invention can also be configured as an auxiliary heat source for various plants and a heat source for thermoacoustics.
