Description

The present invention includes a rotating duct connected with blade tips of blades rotating with respect to the ground, a permanent magnet disposed in an annulus, and a shroud that is stationary with respect to the ground and water (including on board), or Between a rotating rotating duct or a rotating coil or a power generating coil or an electromagnet disposed on a shroud that can rotate in the opposite direction to the ring (hereinafter sometimes referred to as an “electromagnet” regardless of the presence or absence of an iron core) The present invention relates to a wind power generation apparatus that generates electric power using changes in magnetic field lines and a structure thereof.

The use of windmills as a power source for pumping, irrigation or milling has been widely practiced since BC. However, it is relatively new to use for power generation, and is said to be from a windmill made in 1891 by Paul La Coeur in Denmark. The windmill created at that time was a horizontal axis windmill with drag blades connected to a DC generator. Later, horizontal axis wind turbines began to use lift blades that generate and rotate the same lift as aircraft wings and propellers. In addition, vertical axis wind turbines have also been improved, and Savonius type that can use drag more effectively, Darius type and gyromill type that have lift blades attached to the vertical axis, and the generator is an induction type AC generator and A combination of a synchronous alternator and a converter has become efficient.

In wind power generation, there are devices that generate electricity by vibrating piezoelectric elements with the force of wind, and devices that generate electricity by generating static electricity, but in general, a conducting wire that runs in a magnetic field created by a permanent magnet is run. The induced current when the conductor cuts the magnetic field is used. Usually, the generator is connected to a rotating shaft that is rotated by a windmill. Therefore, the magnitude of the generated electric power is proportional to the speed of the wire crossing the magnetic field. Therefore, in the case of a generator connected to the rotating shaft of the windmill, an attempt is made to increase the power generation efficiency of the rotating shaft of the generator. Since it is necessary to increase the speed, there is a history of exploring the selection of a wind turbine type or blade type with a high rotational speed of the wind turbine rotation axis, or the installation of a speed increasing device or an increase in the number of generator poles.

Wind turbines are roughly divided into horizontal axis wind turbines and vertical axis wind turbines. Horizontal axis wind turbines include multi-blade types with drag blades, Dutch types, sail wing types, and propeller types with lift blades. In addition, each blade is facing the wind direction (however, the American type of multi-wing type is often used in parallel or at an angle by operating the tail blade) Wind utilization efficiency is good. However, since it is necessary to face the wind direction, it is usually necessary to accompany the swivel device. Of the horizontal axis wind turbines, one drag blade cannot have a peripheral speed ratio of more than 1, but has a high torque and may rotate even in winds with a wind speed of less than 3 m / s, resulting in a low cut-in wind speed. The other lift blade has a peripheral speed ratio of up to about 5 and can increase the number of rotations of the rotating shaft, so it is suitable for power generation. However, the torque is low, and if it is overloaded from the beginning, excitation as the initial motion is necessary. As with the wing stall speed found in aircraft, it cannot be turned without a certain wind speed, so the cut-in wind speed is high. A vertical axis wind turbine can deal with wind from any direction, but it is inefficient because only about half of the wind can be used. Like the horizontal axis wind turbine, the vertical axis wind turbine has drag blades and lift blades, the characteristics of which are the same as in the case of the horizontal axis wind turbine. Darrieus type or gyromill type is used.

In a normal wind power generator that generates power by connecting a rotating shaft to a DC generator (DC motor), an induction generator (induction motor), or a synchronous generator (synchronous motor), the power generation efficiency is increased. For this purpose, it is necessary to improve the rotational speed of the rotating shaft of the generator. Therefore, there are many power generation examples that employ a propeller type that is a lifting blade of a horizontal axis wind turbine that can increase the rotation speed, but the propeller type has a drawback of low torque. In the propeller type, the larger the rotation radius, the greater the torque but the slower the rotation speed. In the case of the same radius of rotation, the greater the number of blades, the greater the torque but the slower the rotational speed. Thus, in the propeller type, torque is insufficient with a small turning radius, and with a large turning radius, the number of revolutions does not increase and it is difficult to achieve both torque and revolutions. Accordingly, there is a propeller type in which the number of blades is one with a large turning radius in order to make both of them as compatible as possible. However, in general, in the case of induction generators and synchronous generators of about 6 poles, the propeller type blades are set to about 3 with a large turning radius, and a speed increaser of about 5 times is interposed on the rotating shaft of the propeller. I often turn the generator. In some cases, the number of poles of the synchronous generator is increased to about 40 to 60 poles, and power is generated without using a speed increaser.

In Patent Document 8 and Patent Document 38, in a propeller type of a lift blade of a horizontal axis wind turbine, in order to improve torque, a propeller type lift blade is provided on the upwind side which is the windward side of the nacelle and the downwind side which is the leeward side. This is an example in which two sets are installed one by one, and the output is mechanically extracted from the rotating shaft of the windmill. On the other hand, in Patent Document 38, the rotation direction of the lifting blade on the up window side and the rotation direction of the lifting blade on the down window side are the same direction. However, the lift blades on the downwind side are affected by the wake flow of the lift blades on the upwind side and the eddy current created by the nacelle and struts. In this case, the power generation device has a mechanism for generating power through a differential gear (differential gear), which is one of differential devices, and then connected to a speed increaser. The other patent document 8 is a type in which the lift blades on the upwind side and the downwind side sandwiching the nacelle are coaxially reversely rotated (hereinafter referred to as “coaxial inversion”). Also in this case, the lift blades on the downwind side are affected by the lift blades on the upwind side and the vortex created by the nacelle and the support column. Therefore, although there is a large difference in rotational speed between the two sets of lifting blades, both outputs are directly connected to the rotating shaft of the generator with bevel gears. For this reason, the bevel gear adjusts the different rotational speeds and torques of the two lift blades before and after the nacelle, so that a large unreasonable force is applied and it is extremely difficult to use for a long time. Further, Patent Document 8 claims that the upwind side lift blades and the downwind side lift blades are coaxially reversed, so that the rotational speed of the rotary shaft is doubled, so that a speed-up gear is not required. However, when the output is mechanically extracted, the rotational speed of the output shaft is almost the same as that of a pair of lifting blades, whether it is rotating in the same direction or reversing coaxially, or down. The speed of the blades on the wind side becomes a brake, which is slower than the case of one set, and the reason that the gear box is unnecessary is to be formed only by using two sets of lift blades with coaxial reversal I can't.

Patent Document 25 and Patent Document 37 have two pairs of drag blades of the vertical axis wind turbine up and down, Patent Document 11 and Patent Document 18 and the above Patent Document 37 have two sets of lift blades of the horizontal axis wind turbine in the front and rear, A permanent magnet is connected to one of the blades, and a coil with windings is connected to the other to invert the axis, and the relative speed of each other is almost doubled to generate power. The use of coaxial reversal when electromagnetically extracting the peripheral speed is an excellent method in which an increase in relative speed can be expected unlike the case where the output of the rotating shaft that rotates in reverse is mechanically extracted. However, the surface of the permanent magnet facing (facing) the electromagnets of these patent documents that exhibits the strongest magnetic force (hereinafter referred to as the “working surface” of the permanent magnet). the surface ") and the working surface of the electromagnet, similar to the conventional electric motor, since arranged in diametrical direction of the sensitive plane of rotation of the expansion by the expansion and temperature changes caused by the centrifugal force, the working surface of the permanent magnet and the counter The gap formed by the working surface of the electromagnet is only possible in the case of a relatively small diameter that is hardly affected by centrifugal force or temperature change, and is difficult to implement at a large diameter.

Patent Document 40 discloses a mechanism for generating electric power by using electromagnetically the speed of a peripheral portion (hereinafter referred to as “peripheral speed”) of a rotating blade of a vertical axis wind turbine in wind power generation (including hydroelectric power generation). is doing. The mechanism that uses the peripheral speed is to connect the outer side of the square paddle, which is a drag blade, with a disk (hereinafter referred to as “ring”) and incorporate the power generation mechanism there, Two examples are shown in the case where a ring is provided on the rotating shaft side and a power generation mechanism is attached. In the claims of the specification and the detailed description of the invention, four important features of the present invention are described. That is, the first is that the permanent magnets and electromagnets are arranged in a circle around the periphery of the rotating blades. The second is to generate electricity using the peripheral speed of the blades based on the fact that magnets are arranged in the ring. The third is to generate electricity by stacking multiple circular rings with permanent magnets and electromagnets. Fourth , the relative speed between the working surface of the permanent magnet and the working surface of the opposing electromagnet is obtained by using the inner square paddle wind turbine and the outer circular paddle wind turbine coaxially and using the rotation directions in directions opposite to each other. To generate electricity. Furthermore, from the contents of the drawing in the drawing, the opposing working surfaces of the permanent magnet and the electromagnet are set in a direction parallel to the rotation axis of the windmill. The basic procedure for creating a large windmill is disclosed because it is less affected by the expansion and contraction caused by. The wind turbine disclosed in Patent Document 40 is a vertical axis wind turbine in the case of a drag blade, but even if it is replaced with a lift blade of a horizontal axis wind turbine, it can be applied almost as it is.

Both Patent Document 17 and Patent Document 23 use Savonius type drag blades for a vertical axis wind turbine. Both the inventions are learning kits and are not invented for the purpose of utilizing the peripheral speed, but as a result, the action surface of the permanent magnet and the action of the electromagnet are parallel to the rotating shaft in the periphery of the windmill. This is an example of generating electricity with the surface facing . Patent Document 5 uses a gyromill type lift blade for a vertical axis wind turbine. In Patent Document 5, a power generating coil is installed in an annular shape, and the power generating coil is sandwiched between the inner side and the outer side of the rotating shaft by permanent magnets mounted side by side in the diameter direction at the upper and lower ends of the rotating lifting blade. This is a method of generating electricity. For this reason, if the rotating part has a small diameter that is less affected by expansion due to centrifugal force or expansion / contraction due to temperature change, it can be realized, but it is difficult to realize it with a large diameter. Patent Document 3 is based on the gyromill type of lift blades of a vertical axis wind turbine as in Patent Document 5, but the spokes connecting the gyromill vertical straight blades and the rotating shaft have the shape of lift blades. ing. Regarding the arrangement of the permanent magnet and the power generating coil of Patent Document 3, the diameter direction orthogonal to the rotation axis, the direction parallel to the rotation axis, the both directions of the diameter direction and the direction parallel to the rotation axis, or the permanent magnet Various ways of arrangement are shown, such as the direction in which the coil is sandwiched from both sides by the power generating coil. In this, a permanent magnet is placed on a guide mechanism on which a slider travels on a guide to travel between power generating coils, or the power generating coil side is covered with a cover to prevent contact with the traveling permanent magnet, etc. , A device to maintain the gap between the permanent magnet and the power generation coil against expansion and contraction due to temperature change, and Patent Document 19 attempts to reduce rotational resistance by using a magnetic bearing on the main shaft of a vertical axis wind turbine with S-shaped rotor blades However, when either a permanent magnet or a power generation coil is used as a rotor, a mechanism of a magnetic bearing is used between the frame and the rotor to reduce friction and maintain the rotating shaft. Guide mechanisms and magnetic bearings are effective in maintaining a gap between a permanent magnet and a power generation coil in a vertical axis wind turbine with a relatively small radius of rotation, but even if the diameter is considerably large, power generation is possible. It is necessary to examine whether the gap with the coil can be effectively maintained. In Patent Document 3, an example of a horizontal axis wind turbine is also shown in FIG. 18, and in a horizontal axis wind turbine that is often a wind turbine having a large diameter, a permanent magnet or a power generation coil is not installed at the blade end of the blade. The power generation coil supported by the ring and frame is installed in the middle part of the blade. In this way, as Patent Document 3 considered to be better with FIG. 18 by itself, this method is applied as it is to the blade tip of a large-diameter blade of a horizontal axis wind turbine, which is sometimes several tens of meters. It is extremely difficult to maintain the gap between the permanent magnet and the power generation coil at 1 to 5 mm as contemplated by Patent Document 3 in order to withstand rattling and distortion due to manufacturing errors. In addition, when installed at the blade tip of a horizontal axis wind turbine with a turning radius of 50 m, the guide is passed to the circumference of about 314 m, and it is resistant to the sun, wind and snow, and various vibrations. It is extremely difficult to maintain the accuracy of the gap. Furthermore, if it is desired to reduce the gap between the permanent magnet and the power generation coil to 1 mm or less in order to improve the power generation efficiency, it is almost impossible with this method, and further contrivance is necessary.

Patent Document 7, Patent Document 30 and Patent Document 34 are drag blades, Patent Document 16 and Patent Document 22 are lift blades attached to a horizontal axis wind turbine, and the invention pursues efficient power generation by utilizing the peripheral speed to the maximum. It is. The former constitutes a power generation mechanism consisting of permanent magnets and electromagnets by connecting the blade tips of the blades with a ring, and the latter constitutes a power generation mechanism by connecting the middle part of the blades and the blade tips. . However, of these inventions, except for Patent Document 7, in other Patent Documents, the working surface of the permanent magnet , which is the main part of power generation, and the working surface of the electromagnet facing the diameter are perpendicular to the rotation axis of the windmill. Since they are arranged in the direction, it is difficult to make a large-sized one that is easily affected directly by expansion due to centrifugal force and expansion / contraction due to temperature change. For example, when the radius of the blade of the horizontal axis wind turbine is 50 m and the extension due to the centrifugal force is about 0.1%, the extension occurs when the centrifugal force reaches the maximum from the state where the centrifugal force is not applied. The length is 50 mm. Power generation using peripheral speed comes from the pursuit of power generation efficiency, but power generation efficiency depends on how narrow the gap between the working surface of the permanent magnet and the working surface of the electromagnet can be maintained. Although it is desirable if 1 mm or less can be maintained, if 1 mm is maintained when 50 mm is extended, the gap at the beginning of rotation where no centrifugal force is generated must be 51 mm. Below this, it cannot be turned in contact. In such a large gap, efficient power generation cannot be performed, and it is not possible to take advantage of power generation efficiency by using the peripheral speed.

As described above, many of the power generation attempts using the peripheral speed do not take into consideration the expansion due to the centrifugal force of the blade tip portion or the expansion / contraction due to temperature change. In particular, Patent Document 16 has inner and outer rings for disposing permanent magnets and electromagnets, and has lift blades inside the inner ring and lift blades outside the outer ring. Although it is intended to improve power generation efficiency by rotating, expansion and contraction due to centrifugal force is not considered at all. The permanent magnet and the electromagnet of Patent Document 16 are arranged in such a manner that they face each other (opposite) on the diameter between the inner ring and the outer ring, and a bearing is provided between the inner ring and the outer ring. It is arranged. At first glance, it seems that this bearing can withstand expansion and contraction of the inner and outer peripheral rings and maintain a gap between the permanent magnet working surface and the electromagnet working surface opposite to the permanent magnet working surface . However, the rotational speeds of the inner ring and the outer ring rotating in the opposite directions are different from each other in the radius of rotation, so it is natural that the blades of the inner ring with a small radius are faster and the blades of the outer ring with a large radius are slower. In addition, in the case of the present invention, a value different from the pitch angle of the blades of the outer ring is given to the pitch angle of the blades of the inner ring, and the inner ring and the outer ring are more than the difference in radius. Are set so that there is a difference in the rotational speed of the blades. Therefore, the centrifugal force is generated more in the inner ring. Even if the influence of centrifugal force is very small, 0.05%, if the turning radius is 2 m, the extension is 1 mm. Even if the extension of 1 mm has no effect in a space where there is nothing, if a load is applied across the bearing, it may become a force to shatter the bearing. If the bearing is in good health, it will cause the base side to go out. Also, even if both the bearing and the base side are alive due to the special material, the inner ring and the outer ring can rotate because of the large force that the bearing and the base press against each other. It is difficult.

In order to improve the power generation efficiency by the windmill, the method using the peripheral speed of the windmill is the best. When the peripheral speed is used electromagnetically, the speed of the conducting wire that cuts the magnetic field can be dramatically improved, and the number of poles to be arranged can be greatly increased. However, when a gap is formed between the working surface of the permanent magnet and the working surface of the electromagnet opposite to the working surface of the permanent magnet at the blade tip, it is essential to be able to cope with stretching due to centrifugal force and stretching due to temperature change. For this purpose, at least, as shown in Patent Literature 7, Patent Literature 17, Patent Literature 23, and Patent Literature 40, it is necessary to configure the respective working surfaces of the permanent magnet and the electromagnet that are parallel to the rotation axis. It is a condition. Furthermore, as the windmill diameter increases , the gap between the working surface of the permanent magnet installed parallel to the rotating shaft and the working surface of the opposing electromagnet may change due to disturbance caused by wind power or distortion during rotation. In addition, it is necessary to properly maintain the gap between the working surface of the permanent magnet and the working surface of the opposing electromagnet , even with respect to wind pressure (load) applied to the blades or rattling due to manufacturing errors.

Patent Document 1 shows a mechanism of a driving portion of a rotor blade of an aircraft, and an operation surface of an electromagnet and an operation surface of a permanent magnet facing the electromagnet are installed in a direction parallel to the rotation axis. Further, a bearing that maintains a constant gap between the working surface of the electromagnet and the working surface of the permanent magnet that is opposite to the working surface of the electromagnet is installed at a position that is not affected by expansion due to centrifugal force of the rotor blades or expansion / contraction due to temperature change. Thus, for example, a mechanism that can always keep the gap between the working surface of the electromagnet and the working surface of the permanent magnet at 1 mm or less by using a bearing that supports only the attractive force due to the magnetic force between the electromagnet and the permanent magnet as a load. Is disclosed.

The wind turbine having lift blades can increase the rotational speed because the peripheral speed ratio can be 1 or more regardless of whether the wind turbine is a horizontal axis wind turbine or a vertical axis wind turbine. However, the torque is low and the cut-in wind speed is high. As an improvement measure for facilitating start-up for this purpose, lift blades are used during rated power generation as in Patent Document 4, Patent Document 6, Patent Document 12, Patent Document 29, Patent Document 31, and Patent Document 32. Aside from this, there is a thing that attaches a drag blade for starting and uses the strong torque of the drag blade and the low cut-in wind speed. Among these, one patent document 4, patent document 29, and patent document 32 isolate | separate the drag blade | wing which finished the role of starting with the clutch mechanism or the ratchet mechanism from the middle of rotation, and use only a lift blade windmill at the time of electric power generation. It is what you do. On the other hand, Patent Document 6, Patent Document 12 and Patent Document 31 use the drag blades at the time of starting together without separating them even during power generation, so most of the characteristics of the lift blades are lost and the rotation does not increase. There is little fluctuation.

Patent Document 33 shows a concept in which a plurality of generators are connected in series to a rotating shaft provided with lifting blades on a horizontal axis wind turbine in a state where each generator can be connected to and disconnected from each other. The generator connected to the rotating shaft of the windmill causes the windmill to run idle without being connected at all during the initial period when the wind speed is low. When the wind speed rises and the wind speed at which power generation is possible, the number of sequential generators connected to the rotating shaft of the wind turbine is increased according to the amount of energy of the wind, and finally the total number of generators is connected to the rotating shaft. When the total number of generators is connected to the windmill, there is an effect of reducing the rotation speed of the windmill due to a heavy load, but when the wind speed increases and the rotation speed becomes excessive, some generators It shows that the current is passed and used as a brake. However, when the generator is used as a brake, current in the same direction flows at the same time when the generator originally generates power, so that a larger current flows through the coil of the electromagnet. Therefore, since the calorific value rises rapidly, it is necessary to provide a device with a cooling device.

Patent Document 28 shows the concept of the procedure for connecting and disconnecting a plurality of coils by replacing the generator of Patent Document 33 with the number of coils inside the generator. Patent Document 26 shows a method of directly connecting a resistor instead of a generator as one of the specific points of the electromagnetic brake part of Patent Document 33. Patent Documents 10 and 24 show electromagnetic brakes when Patent Document 33 shows load reduction or excessive rotation at the start of rotation of a windmill by separating and connecting a plurality of generators. This shows the mechanism of electromagnetic density with an electromagnet. Patent document 13 and patent document 20 show the point in the case of performing with a mechanical clutch apparatus about the idle running point at the time of a windmill's rotation start, and the connection point of a generator when a wind speed rises sequentially.

Countermeasures for strong winds are important in order not to damage or damage the structure of the windmill, and also to prevent burning of the coil for power generation. As countermeasures, in a horizontal axis wind turbine, the pitch angle of the blades is changed to be parallel to the direction of the wind, or the wind turbine itself is made parallel to the direction of the wind to flow the wind. Patent Document 27 is designed to withstand strong winds by tilting upward, which was also used in the so-called Yamada windmill type, and there are many similar to the change in the pitch angle and the direction of the windmill itself. There are past achievements that have been implemented. On the other hand, Patent Document 2, Patent Document 15, Patent Document 36, and Patent Document 39 all take measures against strong winds by reducing the rotation radius of rotating blades during strong winds, and do not necessarily have a track record. . Of these, Patent Document 15, which is one vertical axis wind turbine, is an invention using a gyromill type lift blade, and it is described that even if the wind speed is about 0.5 m / s, it rotates regardless of the direction of the wind. ing. However, the lift blades, like the aircraft wings, have wind speeds that correspond to the stall speed, so there is considerable difficulty, although it cannot be said in general because of the relationship with the wing surface load. Patent Document 2, Patent Document 36, and Patent Document 39, which are the other horizontal axis wind turbines, all use propeller-type lift blades and are common except that a wind turbine for control is installed in Patent Document 2. There are many parts. In particular, FIG. 11 of Patent Document 2 and FIG. 1 of Patent Document 39, and FIG. 1 of Patent Document 36 are almost up to the point where the lift blades are attached to the downwind side of the horizontal axis wind turbine and the blades fall to the leeward side by the wind. It is common. However, there is a decisive difference between FIG. 11 of Patent Document 2 and FIG. 1 of Patent Document 39 and FIG. That is, in the former two, both the blades attached to the support member (hereinafter referred to as “flapping hinge”) that attaches the blades to the rotating shaft in a state where the blades are tilted downwind, wind the portion that hits the back of the chord. In the upward direction, the latter is mounted in parallel to the wind direction, and the two blades are described as being 90 ° differently mounted. Even if the attachment of the blades is different by 90 °, there is no lift blade that rotates in the same manner, and either of them may not be able to rotate. That is, the former uses the same blade shape as the helicopter, but cannot be found in a propeller type windmill. Household fans use drag blades on the horizontal axis, so when they are turned off and exposed to natural wind, they react well to the wind from the direction perpendicular to the recesses, but rotate perpendicularly to the projections. The direction of the wind rotates only at about 1/3 speed in response to the wind of the recess. Even with drag blades, the response of the back part of the chord to the wind is this level, so even if the wind is applied to the back part of the chord of the lift blade, it hardly rotates or rotates. Even so, it is extremely difficult to generate torque enough to turn the generator. Therefore, in this method, only Patent Document 36 is considered to have a rotatable mechanism.

Therefore, considering whether Patent Document 36 is effective as a countermeasure against strong winds by reducing the rotation radius during rotation in strong winds, the rotation speed is usually slower when the rotation radius is larger and faster when the rotation radius is smaller. As described, when the rotation radius is reduced, the rotation is suppressed and the torque is certainly reduced, but the rotation is not slowed down. The same applies to Patent Document 15 of the vertical axis wind turbine. In addition, while the rate of torque increase / decrease is proportional to the radius of rotation, wind energy is proportional to the cube of the wind speed, so the windmill can sufficiently rotate except when the radius of rotation is zero. Therefore, since the power generation amount of the windmill far exceeds the power generation amount when the wind speed is low, there is a risk of burning the power generation coil, which is the result contrary to the intention of the inventors. If the lifting blades are opened and closed according to the physical principle, the helicopter flapping hinge used in Patent Document 2 is effectively used, and the centrifugal force during rotation is used as it is. It is possible to increase the turning radius and make the pitch angle parallel to the wind direction because it is easy from the well-known technology of the conventional helicopter. In addition, as in Patent Document 2 and Patent Document 39, a special use that is difficult to think in the normal case of exposing the maximum area of the blade (the back part of the chord) to the wind despite the fact that it is a windmill of a lift blade. In the case of the law, there is a possibility that the blade is pushed down to the leeward with a force strong enough to cancel the centrifugal force, but when using the lift blade as usual, at least the end of the blade is on the windward side. On the other hand, only a small area is exposed, so there is little possibility of being pushed down by the lee. However, even in the method of using the flapping hinge in accordance with the physical principle as described above, since dragging and hunting occur, it is necessary to install a dragging hinge (lead lug hinge) or the like similar to the helicopter. Therefore, the conventional method of changing the direction of the entire wind turbine or changing the pitch of the blades is more likely to be more effective in terms of installation cost and effect than the method of changing the rotation radius.

The wind speed of the wind fluctuates depending on the wind. In particular, in Japan, where the mountainous areas are more complicated than in Europe, where westerly winds blow on the flat ground, the wind fluctuates in a short time. Minor fluctuations in wind speed will reduce the quality of power generation, so we want to stabilize it. As physical means for that purpose, Patent Document 21 and Patent Document 35 attempt to stabilize by attaching a flywheel to the rotating shaft of the windmill.

Windmill damage due to lightning strikes is mostly in the horizontal axis wind turbine propeller type, accounting for about 40% of breakdowns. Therefore, a lightning rod is set up in the vicinity of the windmill or a lightning rod is set up on the nacelle to prevent lightning at the main part of the windmill.Especially in winter, static electricity tends to accumulate in the resin blades, and in the winter thundercloud Has a high potential, making it difficult to prevent lightning strikes on the blades. Patent Document 9 and Patent Document 14 describe a lightning rod installation procedure and a blade static electricity removal procedure, respectively.

The challenge is to perform efficient wind power generation during rated rotation, and to continue power generation even when the windmills can rotate and become strong winds from the time when the wind is weak.

In the present invention, as a means for performing efficient power generation, which is the first problem, power generation using the peripheral speed shown in Patent Document 40 is adopted and developed. For this purpose, a rotating duct and a ring for connecting the blade tips of the wind turbine blades are prepared. The ring is used when the load of the windmill is mainly supported by the rotating shaft of the windmill and there is almost no transmission of the load in the ring. The rotating duct is a bulging overhang (hereinafter referred to as a “hanger”) that transmits the load of the windmill to the shroud on the upper and lower parts of the ring in a vertical axis windmill, and on the front and rear parts of the ring in a horizontal axis windmill. It is used when the load is supported via the upper and lower hangers or the front and rear hangers. If the permanent magnet is a rotating duct, it is attached to the upper (front) hanger (hereinafter referred to as “upper hanger / front hanger”) and the lower (rear) hanger (hereinafter referred to as “lower hanger / rear hanger”). Arrange. In the case of a ring, the ring is disposed on a protrusion (hereinafter referred to as “ring plate”) that goes around the outer periphery of the ring. A shroud is provided on the outer periphery of the rotating duct and the ring, and an electromagnet is provided on the inner periphery of the shroud. In this way, when the wind turbine rotates, the induced current is generated when the winding of the electromagnet on the inner periphery of the shroud cuts the magnetic field of the upper hanger / front hanger, lower hanger / rear hanger, or the permanent magnet on the ring plate. It is possible to generate power efficiently using the peripheral speed.

In the present invention, the working surface of the permanent magnet disposed on the rotating duct or the ring and the working surface of the electromagnet disposed on the inner peripheral portion of the shroud are opposed (facing) with a positional relationship parallel to the rotating shaft of the windmill. Yes. Therefore, the gap , which can be said to be the vertical distance between the working surface of the permanent magnet and the working surface of the electromagnet, is less affected by expansion and contraction due to the centrifugal force of the windmill and temperature change. However, always keeping the gap between the working surface of the permanent magnet and the working surface of the opposing electromagnet at, for example, 1 mm or less is a change in wind pressure or load when the windmill moves (including gyro precession), or It is difficult because it is affected by the manufacturing error of the windmill. Therefore, by using the gap holding bearing used in Patent Document 1 for holding the gap between the permanent magnet and the electromagnet of the windmill, the action of the permanent magnet of the windmill regardless of changes in wind pressure, changes in load, or manufacturing errors. It is possible to easily maintain a constant gap between the surface and the working surface of the electromagnet facing the surface .

As a second problem in the present invention, as a mechanism for rotating a windmill from a time when the wind speed is weak and continuing power generation even at a certain intense wind speed, the concept of separation and connection of a plurality of power generation devices of Patent Document 33 and Patents The concept of changing the degree of electromagnetic coupling between the permanent magnet and the electromagnet disclosed in Document 24 and Patent Document 10 is adopted and developed. For this reason, the arm portion of the device that supports the electromagnet arranged on the shroud side is expanded and contracted to change the electromagnetic density of the permanent magnet on the rotating duct or ring and the electromagnet on the shroud side. The wind turbine can be rotated even at low wind speeds, and when the wind turbine begins to rotate, the relationship between the permanent magnet and the electromagnet is gradually increased from coarse to dense, and when the wind is strong, the permanent magnet and the electromagnet This is a mechanism that can be adjusted so that excessive current is not generated in the winding portion of the electromagnet by reducing the power generation amount by electromagnetically coarsening again. Moreover, although an electric current is passed through the electromagnet as necessary, it is also used as a brake. In this case, an electromagnet having a cooling device is used because a large current flows through the winding of the electromagnet and the amount of heat generation increases rapidly.

When power generation using the peripheral speed of the blades is performed with the rotating duct of the present invention or the permanent magnet on the ring side and the electromagnet on the shroud side, it is much higher than when a generator is connected to the conventional rotating shaft. The winding of the electromagnet at a speed cuts the magnetic field of the permanent magnet and generates an induced current, so that efficient power generation can be performed. In addition, since the power generation apparatus used in the present invention uses the gap holding bearing shown in Patent Document 1, it is resistant to external pressure and disturbance to the windmill, or manufacturing errors, and the working surface of the permanent magnet that affects the power generation efficiency. Since the gap between the electromagnet and the working surface of the electromagnet facing each other can always be reliably maintained, the power generation efficiency is good. Also, the holding skeleton used together with the electromagnet and the gap holding bearing set expands and contracts the arm part of the device, electromagnetically cuts the relationship between the permanent magnet and the electromagnet, and continuously switches the density. Therefore, when the wind turbine starts to rotate, the load is cut off, the power generation amount is increased or decreased continuously and arbitrarily according to the wind force, or the wind turbine rotation speed increases excessively due to the strong wind. The relationship between the permanent magnet and the electromagnet can be electromagnetically roughed to prevent burning of the coil of the electromagnet for power generation. In addition, for small wind speed fluctuations, a rotating duct or an annulus can replace the flywheel to absorb the fluctuations and maintain stable rotation. In addition, in the case of a horizontal axis windmill that is heavily damaged by lightning, the blades are covered with rotating ducts, rings, and shrouds, so it is not only easy to remove static electricity from the blades, but also installed directly on the shroud. Alternatively, since the lightning rod can be installed in contact with the shroud with a slip ring, the risk of lightning strike can be greatly reduced. In addition, when the wind turbine is covered with a shroud, both vertical and horizontal axis wind turbines can be supported by the shroud in addition to the rotating shaft, which makes it more robust and increases design freedom and matches the landscape. Make it easy to do. In addition, if the blade tips are connected by a rotating duct or ring and the rotating duct or ring is held by a shroud, it is not always necessary to connect the blade to the rotating shaft in the center of the windmill. If the shape is hollowed out, it can be expected that a creature such as a migratory bird can easily see the rotation range of the windmill even when viewed from the air, and the number of bird strikes can be reduced. In addition, wind noise generated at the blade tip and anomalous sound caused by the difference in rotational speed between the blade tip and blade root cover the blade tip with a rotating duct or ring, and the blade core (blade root) part. By removing the wings, it can be greatly relieved, so it can contribute to the social life environment.

The power generator of the present invention is composed of five main parts that are related to each other. That is, a train wheel type electromagnet (1) in which a winding (105) is wound around an axis (6) in the shape of a train wheel type, and an electromagnet that is placed on the electromagnet and that faces the working surface of the permanent magnet. The gap holding bearing (2) for properly maintaining the gap (999) with the working surface of the magnet and the set of the electromagnet (1) and the gap holding bearing (2) are electromagnetically coupled to the permanent magnet (4). Shim (5) additionally used as necessary to finely adjust the spacing (space) between the holding skeleton (3) for adjusting the roughness and the electromagnet (1) and the gap holding bearing (2) And the upper hanger / front hanger (31) and the lower hanger / rear hanger (32) of the rotating duct (30), or the ring plate (35) of the rotating duct (30) and the ring (34). And a permanent magnet (4).

The train wheel type electromagnet (1) used in the present invention is made of an iron material suitable for an electromagnet such as silicon steel, and is composed of one shaft portion (104) and one outside of the shaft portion in the longitudinal direction. It is assumed that it is usually composed of two flange portions (103) and two wheel portions (101) in total, one on the outer side of the flange portion. The central shaft portion (104) of the shaft center (6) is usually a cylindrical shape having a minimum diameter, but a quadrangular or polygonal shape, or a bundle of several of them, or a gas or liquid for cooling. You may provide the hollow part for letting it pass. When the train wheel type electromagnet (1) is used under superconductivity, the hollow portion may be used as a passage for the superconducting coolant. A winding (105) is wound around the shaft (104) to constitute an electromagnet. The train wheel type electromagnet (1), which is an electromagnet, has a wheel portion (101) fitted into an installation hole (205) penetrating from the top surface to the bottom surface of the case (203) of the gap holding bearing (2), and a flange portion. It stops at (103) and is installed on the case (203) of the bearing (2) for holding the gap.

The gap retaining bearing (2) of the present invention has three roles. The first is to install and integrate the train wheel type electromagnet (1) in the installation hole (205) of the gap holding bearing (2). Second, after installation, from the bottom of the gap retaining bearing (2), in the direction of the upper hanger / front hanger (31) and lower hanger / rear hanger (32) of the rotating duct (30), or the rotating duct (30) and the vertical distance between the train wheel type electromagnet (1) looking into the working surface in the direction of the ring plate (35) of the ring (34) and the working surface of the permanent magnet (4) facing it. Determine the gap (999) that hits. The third is a set of two electric bearing wheel bearings (2) and one permanent magnet (4) of the rotating duct (30) on the top and bottom of one train wheel type electromagnet (1). It runs in a space having a substantially U-shaped cross section created by the upper hanger / front hanger (31) and the lower hanger / rear hanger (32) arranged on each of them, or it is a train wheel type electromagnet ( 1) A ring plate (35) is sandwiched between two sets of one combination and one bearing for holding a gap (2), and travels on the surface.

The gap (999) between the working surface of the train wheel type electromagnet (1) and the working surface of the permanent magnet (4) determined by the gap holding bearing (2) is the case thickness (204 ) of the gap holding bearing (2). ) And the amount of protrusion of the bearing (202), which is the height from the bottom of the case to the far end of the bearing, and the train wheel fitted in the installation hole (205) of the clearance holding bearing (2) It is the length of the difference which subtracted the length (102) of the wheel part from the front-end | tip part of a type | mold electromagnet (1) to the root of a flange part (103). That is, (999) = ((204) + (202)) − (102). The gap (999) between the working surface of the train wheel type electromagnet (1) once determined in this way and the working surface of the permanent magnet (4) facing the train wheel type electromagnet (1) and permanent magnet (4 ) Between the case (203) and the bearing (201).

The clearance holding bearing (2) holds the gap between the working surface of the permanent magnet (4) and the working surface of the electromagnet (1) in the upper hanger / front hanger in which the permanent magnet (4) is disposed. Even when one electromagnet (1) and two gap retaining bearings (2) are inserted and used in the space between (31) and the lower hanger / rear hanger (32), the permanent magnet (4) is arranged. The same applies when the ring plate (35) provided is sandwiched between two sets of one set of one electromagnet (1) and one gap holding bearing (2). Further, when the ring plate (35) provided with the permanent magnet (4) is sandwiched and used, instead of using two sets of one electromagnet (1) and one gap holding bearing (2), U It is also possible to use a gap holding bearing (2) at both ends of one of a letter-shaped or horseshoe-shaped (hereinafter referred to as "substantially U-shaped" ) electromagnet instead of a set of two sets. it can.

The material for the gap holding bearing (2) is not only a conventional iron material, but either one or both of the bearing (201) and the case (203), nonferrous metal, ceramic, Alternatively, it is desirable to use a synthetic resin. The configuration consists of a cylindrical bearing (201) and its case (203). The bearing (201) is housed in the case (203), and the inner surface of the space formed by the upper hanger / front hanger (31) and the lower hanger / rear hanger (32) has a protrusion from the bottom surface of the case (203). And the surface of the ring plate (35). The outer shape of the case (203) may be an ellipse, a triangle, or other polygonal shapes depending on the number of bearings. However, the present invention mainly uses a rectangular parallelepiped, and a total of 4 pieces, one at each of the four corners. There is a single bearing (201), and there is an installation hole (205) penetrating from the top surface to the bottom surface of the case (203) at the center. The bearing (201) used in the present invention is mainly a cylindrical needle bearing, but when the rotating duct has a small diameter, the portion far from the center of rotation is slightly larger in diameter and the diameter of the portion close to the center of rotation is smaller. Slightly smaller tapered cylinders or spherical bearings may be used.

The installation hole (205) can be fitted with a wheel portion (101) of a train wheel type electromagnet (1) or an electromagnet wheel portion (101) equivalent to another shape to install an electromagnet. The interior space of the case (203) is provided with at least two bearings (201) having protrusions on the bottom surface of the case, and is filled with a lubricant / lubricant (206) such as grease, oil or molybdenum compound. be able to. Depending on the situation, the permanent magnet (4) of the upper hanger / front hanger (31), the lower hanger / rear hanger (32), or the permanent magnet (4) of the ring plate (35) should fail and protrude from the rotating surface. In such a case, a protective sled (106) for minimizing damage to the electromagnet on the shroud (20) in that case may be mounted on the bottom surface of the gap holding bearing (2).

The holding skeleton (3) of the present invention has, for example, a shape in which a human is sitting with his back on the wall and both hands and both legs are pushed out horizontally, and the portion that hits the back is connected to the inner periphery of the shroud (20). Thus, one of the upper and lower arms and legs is the side of the gap holding bearing (2), and the other is the side of the gap holding bearing (2) or the substantially U-shaped electromagnet (11). To determine the horizontal distance between the rotating duct (30) or the permanent magnet (4) on the ring (34) side and the electromagnet ((1) or (11)) on the shroud (20) side, and the permanent magnet The electromagnetic density between (4) and the electromagnet (1) is adjusted.

The arm of the holding skeleton (3) has a hydraulic pressure generating motor (301) and a hydraulic piston (302) in the device in addition to the one having no expansion / contraction function. 303), a hydraulic pipe (304) connected from the outside of the apparatus, a hydraulic cylinder telescopic arm (303) is moved, and a worm screw rotating electric motor (305) is incorporated, and the worm screw telescopic arm There is a device having a part (306) and a device for connecting a pneumatic pipe (308) from the outside of the device and driving a worm screw rotating air turbine (307) to rotate the worm screw telescopic arm portion (306). In the type having the arm portion, the permanent magnet (4) and the electromagnet (1) according to the strength of the wind, as in the example of the state of electromagnetic density between the permanent magnet and the electromagnet of the generator shown in FIG. Electromagnetic dense It is possible to adjust the amount of power generation by changing the engagement at any time.

The shim (5) of the present invention finely corrects the insertion amount when the wheel portion (101) of the train wheel type electromagnet (1) is inserted into the installation hole (205) of the gap holding bearing (2). Thus, the gap (999) between the working surface of the train wheel type electromagnet (1) and the working surface of the permanent magnet (4) facing the fine adjustment is adjusted. However, when the power generator of the present invention is assembled, fine adjustment by the shim (5) is not required when the dimensional accuracy of the train wheel type electromagnet (1) and the manufacturing accuracy of the gap holding bearing (2) are high. There are many cases. The material of the shim (5) is selected from stainless steel, non-ferrous metal, glass fiber, carbon fiber, Kevlar fiber, rubber, synthetic resin, or made by combining or bonding some of them. . The shim (5) is an extremely thin plate or film and may have any shape, but the center part is for passing the wheel part (101) of the train wheel type electromagnet (1). It is necessary to have a notch.

The permanent magnet (4) is embedded in the upper hanger / front hanger (31), the lower hanger / rear hanger (32), or the ring plate (35) of the rotating duct (30). The permanent magnet (4) is generally vulnerable to heat and loses its magnetization when exposed to high temperatures. Therefore, the upper hanger / front hanger (31) and lower hanger are used in the process of producing the rotating duct (30) and the ring (34). / The rear hanger (32) or the ring plate (35) is cut to embed the permanent magnet (4).

In order to firmly hold the gap (999) between the working surface of the permanent magnet and the working surface of the electromagnet, it is best to arrange the gap holding bearing (2) directly below or just above the electromagnet. With this method, even if the wind turbine has a large diameter and a large external pressure such as wind pressure applied to the wind turbine or a large load caused by the disturbance , the working surface of the train wheel type electromagnet (1) and the working surface of the permanent magnet (4) The gap can be held firmly. However, if the diameter (rotation radius) of the rotor blade is small and the external pressure resulting from wind pressure, etc. or the load resulting from disturbance is small, the free action can be easily reduced in place of the sturdy and heavy bearing (2). A bearing (501) can be used. The electromagnet in this case is a train wheel type electromagnet (1) and has a wheel portion (101) and a flange portion (103) as in the case of using the gap holding bearing (2). instead of the case (203) of the holding bearing (2), a shape aspect consists thin plate having an opening in the rotating duct and the annular direction in the shape of a substantially U, vertical-shaped substantially U Installation hole (205) for attaching the wheel part (101) of the train wheel type electromagnet (1) in the center part slightly close to the back part when the part is the back part, and the free action bearing (501) at the end part far from the back part Has a free action bearing installation hole (506) for mounting a train wheel type electromagnet (1) in the installation hole (205) and free action bearing in the free action bearing installation hole (506). (501) to be able to the attached integrated set, plate used to fix the shape of the back of the generally U on the inner peripheral portion of the shroud (hereinafter, referred to as "the electromagnet-free action bearing support plates") ((503) or (504)) is used. Therefore, the back part, which is one end of the electromagnet free action bearing support plate ((503) or (504)), is fixed to the inner periphery of the shroud, and the free action bearing (501) is attached to the other end, and the train wheel type electromagnet ( 1) is installed in the installation hole of the electromagnet free action bearing support plate ((503) or (504)), and the permanent magnet (4) facing the working surface of the train wheel type electromagnet (1) is used. Since the gap (999) with the working surface can be held by a combination of the lightweight electromagnet free action bearing support plate ((503) or (504)) and the free action bearing (501), the power generation unit can be reduced in weight. . This system consists of a train wheel type electromagnet (1) in the center and a pair of sandwiched upper and lower bearings (2) between the top and bottom, and an upper hanger / front hanger ( 31) and the lower hanger / rear hanger (32), even when generating electricity, put the electromagnet (1) on the gap holding bearing (2) to make one set, and two sets of permanent magnets for the ring plate (35) Even in the case of generating power with (4) in between, it can be implemented with similar changes.

Opposite the working surface of the train wheel type electromagnet (1) in the case of the combination of the train wheel type electromagnet (1), the free action bearing (501) and the electromagnet free action bearing support plate ((503) or (504)) The gap (999) between the permanent magnet (4) and the working surface is the thickness of the electromagnet free action bearing support plate (505) and the height of the mounted plate surface to the far end of the bearing. This is the length of the difference obtained by subtracting the length (102) of the wheel portion from the tip of the train wheel type electromagnet (1) to the flange portion from the length obtained by adding the amount (502). That is, (999) = ((505) + (502)) − (102).

After constructing the above power generator in the rotary duct (30), the ring (34) and the shroud (20), the blade tips of the windmill blades are connected by the rotary duct (30) and the ring (34), and the shroud ( 20) When the side is fixed on the ground or on the water (including on the ship), a wind power generator utilizing the peripheral speed is obtained. In addition, two pairs of wind turbine blades are prepared in the vertical axis wind turbine and two pairs in the front and rear in the horizontal axis wind turbine so that they rotate reversely to each other, and one of the blades is rotated by the rotating duct (30) or the ring (34). When the blade tips of the other blades are connected by the shroud (20), the peripheral speed in a faster state can be utilized than when the blades are one set.

In the present invention, the relationship of electromagnetic density between the permanent magnet (4) and the electromagnet (1) can be adjusted by the holding skeleton (3). Therefore, not only the wind load can be reduced by reducing the load during rotation in the light wind period, but also the electromagnetic relationship between the permanent magnet (4) and the electromagnet (1) should be made rough during strong winds. Therefore, the winding (105) of the electromagnet (1) is less likely to burn out. Therefore, the cut-out speed is increased and handling is easy. However, if there is a possibility that the wind turbine may be damaged in the horizontal axis wind turbine due to a more intense wind, the blade attached to the rotatable blade tip fitting (33b) on the inner periphery of the rotating duct (30) The angle-of-attack-changing motor (84) and the angle-of-attack-changing air turbine (86) are used to turn the angle-of-attack-changing worm gear (85) to change the angle of attack of the blades to control the rotation of the windmill or to change the direction In (802), the direction of the windmill is corrected to be parallel to the wind direction, or the elevation of the windmill is changed by the elevation adjustment device (803).

The combined upper and lower hanger / rotating duct is fixed to the inner periphery of the shroud while inserted into the space formed by the upper hanger / front hanger and lower hanger / rear hanger of the rotating duct.

It was set as the Example in the case of setting it as the wind power generator which generates electric power. In the train wheel type electromagnet used at this time, the working surface facing the permanent magnet is one place on one side, so the train wheel type electromagnets are shown in FIGS. 4 (B) (C) and 6 (B) ( As shown in C), a type having a wheel portion only on one side can also be used. In addition, the permanent magnet's attractive force applied to the electromagnet is only from one direction, so if used for a long time, the gap holding bearing may slightly deform into the bottom of the boat toward the permanent magnet.

When attaching the bearing to the inner periphery of the shroud, it has at least two sets of extendable arms (hereinafter referred to as “extensible arm parts”), one of the extendable arm parts holds the gap holding bearing, Connected to the shroud while holding the gap holding bearing and the electromagnet with the telescopic arm, and expanding and contracting the telescopic arm while maintaining the gap (vertical distance) between the permanent magnet and the electromagnet. FIG. 65 is an example showing a structure of a holding skeleton characterized in that the degree of electromagnetic coupling between the permanent magnet and the electromagnet can be changed by adjusting the horizontal distance.

52, 54, and 55 are pedestals for attaching blades to the inner peripheral portion of the rotating duct in a wind turbine having a shroud and the rotating duct, between the inner peripheral portion of the rotating duct and the blade tip of the blade. An embodiment of a horizontal axis wind turbine characterized in that it has a blade tip mounting tool that connects the inner peripheral portion and the blade tip and can attach the blade at an arbitrary angle of attack. It is.

56, 57, 58, and 59 show a wind turbine having a shroud and a rotating duct, in which a blade is attached to the inner peripheral portion of the rotating duct via a rotatable blade tip fixture equipped with a gear. This is an embodiment of a horizontal axis wind turbine characterized in that the angle of attack of the blades can be changed at any time by rotating the gear of the tool with a worm gear attached to an electric motor or an air turbine installed on the inner periphery of the rotating duct.

The power generator using the peripheral speed at the blade tip of the blade using the winding of the permanent magnet arranged in the rotating duct or the ring and the electromagnet arranged in the shroud used in the present invention is in principle a synchronous motor. And a converter, and it is also possible to use a technology of PWM (Pulse Width Modulation) control, which is not accompanied by technical difficulties. Moreover, since a rotating duct, a ring, and a shroud can be handled as a set, it can be easily handled as a generator. The power generator using the peripheral speed according to the present invention is easier to increase the relative speed between the permanent magnet and the electromagnet than the conventional generator connected to the rotating shaft of the windmill, and is used for maintaining the gap. Since the gap between the working surface of the permanent magnet and the working surface of the electromagnet facing the bearing can always be properly maintained by the bearing, the power generation efficiency is high. In addition, the horizontal distance between the permanent magnet and the electromagnet can be adjusted by adjusting the telescopic arm of the holding skeleton to change the electromagnetic density, so the cut-in wind speed can be lowered and the cut-out wind speed can be raised. This makes it possible to generate electricity in more time zones. In addition, when the wind turbine is covered with a shroud, both the vertical axis wind turbine and the horizontal axis wind turbine can be installed more firmly than before. Especially in the case of horizontal axis windmills, if the blade tip is covered with a shroud, it can reduce the wind noise of the blades and prevent dielectric lightning due to static electricity. However, there is an advantageous effect that it is possible to localize an accident at the time of scattering, and it is possible to enable construction in a residential area or a densely populated area that has been difficult to install.
