Description

The present invention relates to a horizontal axis windmill having a ring which is a ring that connects and rotates on the circumference of blades of blades that rotate with respect to the ground or the water (including on board). Or a wind turbine generator that generates power by using a tire as a driving force for rotating a generator by mechanically taking out the peripheral speed of the windmill by abutting a tire on an outer periphery of an annular ring.

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.

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.

Patent Document 10 discloses a mechanism for generating electric power by electromagnetically extracting the speed (hereinafter referred to as “peripheral speed”) of the peripheral portion where the drag blades of the vertical axis wind turbine rotate in wind power generation (including hydroelectric power generation). ing. The mechanism that uses the peripheral speed is to connect the outside of the square paddle, which is a drag blade, with a disk (hereinafter referred to as an “annular ring”), and to incorporate the power generation mechanism there, as well as in the immediate vicinity of the outermost circular paddle. 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 of the opposing working surfaces of the permanent magnet and the electromagnet is increased by using the inner square paddle wind turbine and the outer circular paddle wind turbine coaxially and using the rotation directions in opposite directions. Power generation. 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 10 is a vertical axis wind turbine in the case of a drag blade. However, even if it is replaced with a lift blade of a horizontal axis wind turbine, the wind turbine can be applied almost as it is.

Patent Document 11 and Patent Document 12 both disclose a mechanism for generating power using the peripheral speed of a vertical axis wind turbine, and describe almost the same contents. That is, in Patent Document 11, an electromagnetic mechanism in which a permanent magnet disposed in an annular shape at the bottom of a vertical axis wind turbine rotates around a power generation coil fixed on the ground in a power generation chamber that is directly below the windmill to generate power. In addition, a mechanism for generating power by mechanically contacting the bottom of the vertical axis windmill with a guide roller directly connected to a generator having a rotation axis orthogonal to the rotation axis of the vertical axis windmill at the bottom of the vertical axis windmill is illustrated. ing. In Patent Document 12, a main gear (hereinafter referred to as “large gear”), a chain, a travel path, or a rail is provided at the bottom of a vertical axis wind turbine, and a generator-side sub gear (hereinafter referred to as “small gear”), a sprocket, or a wheel. A mechanism is disclosed in which the generator is rotated by meshing with a large gear or a chain or abutting against a traveling path or rail. In Patent Document 11, the relationship between the rotating shaft of the vertical axis wind turbine and the rotating shaft of the generator is only illustrated in the case of being orthogonal to each other, whereas in Patent Document 12, the positional relationship parallel to each other is also illustrated. . Although not shown, during the description of the specification of Patent Document 12, power is generated by using a combination of a winding coil and a permanent magnet in a rotating vertical axis windmill and a fixed frame around it. The electromagnetic mechanism is also described. Furthermore, Patent Document 12 also mentions the use of rubber wheels as the material of the wheel between the vertical axis windmill and the frame, and also shows how to support the vertical axis windmill at two locations, upper and lower. Therefore, if these mechanisms are applied and the vertical axis wind turbine is replaced with a horizontal axis wind turbine in which the blade ends are connected by an annulus, and the output shaft to the generator can be installed in the part closest to the ground of the horizontal axis wind turbine, It seems to be easy to implement. However, in horizontal axis wind turbines, it is necessary to face the windward, so in vertical axis wind turbines, unnecessary turning is performed. However, the stress of turning in the horizontal direction (horizontal direction) A 90 ° delay occurs due to the gyro precession, so that a small gear or a rotating chain is installed in a portion close to the ground due to stress in the elevation direction (vertical direction). Driving force transmission that comes into contact with the ring, such as sprockets that are installed near the ground and sprockets that are installed on the rotating side or wheels that are installed near the ground and the road or rail This causes the part to swing in the up-and-down direction, separating the contact part and making it unstable, making it difficult to transmit the driving force. Therefore, the wind power generation using the peripheral speed in the horizontal axis wind turbine cannot be realized only by extending the procedure described in Patent Document 11 and Patent Document 12.

Patent Document 9 discloses a mechanism for generating electricity by mechanically taking out the peripheral speed of rotation of the blades of a horizontal axis wind turbine as a rotational driving force in wind power generation. The mechanism that uses the peripheral speed is that the blade tips are connected by an outer peripheral plate (hereinafter referred to as “annular ring” as in the case of the aforementioned “disc”), and has teeth on the outer side where it rotates together with the circular ring. A small gear having a rotation axis parallel to the rotation axis of the gear is arranged on the circumference of the gear and arranged in contact with the diameter to be taken out as a rotational driving force, and then the rotation axis is approximately 90 ° via the bevel gear. It discloses a mechanism for generating power by driving a generator installed near the root (foundation) of the windmill. Further, Patent Document 9 has a blade reinforcement support for reinforcing the longitudinal direction of the blade, and it is said that wind power generation with a large diameter is possible. However, when the positional relationship in which the small gear contacts the large gear is arranged on the diameter in this way, the gear having a large diameter is remarkably stretched due to centrifugal force during rotation and expansion / contraction due to temperature change. Cause difficulties. For example, when the rotation radius is 50 m, if the expansion and contraction combined with the centrifugal force and the temperature change is 0.2%, the expansion / contraction of 100 mm can be considered. Further, a propeller type windmill released by a blade tip, which is common in horizontal axis windmills, supports a rotating shaft so that it can rotate freely from either the leeward side or the upwind side. The support procedure is the same as that of a normal propeller type. However, in the case of a propeller type windmill with the blade tip released, even if the windmill turns in the left-right direction and the stress in the left-right direction is delayed by 90 ° due to the gyro precession and becomes the stress in the elevation direction, the elasticity of the propeller alone However, in the case of Patent Document 9 in which the blade tip is connected by an annular ring without releasing the blade tip, the rotation shaft is moved only from one location on the leeward side as in the case of the normal propeller type. If the windmill is supported in a freely rotatable manner, excessive stress is applied to the bearing of the rotating shaft, and the upper and lower parts of the ring are greatly swung back and forth due to the inevitable deflection of the windmill. There is a high possibility that the abutting portions of the large gear and the small gear constituting the transmission part are disengaged. Therefore, in the case of Patent Document 9 in which a material having poor elasticity such as a gear is arranged in the diameter direction of the windmill, it is difficult to execute.

In Patent Document 2 and Patent Document 8, in a propeller type of a lift blade of a horizontal axis wind turbine, in order to improve torque, a propeller having the same diameter 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 of lifting blades of the mold 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 8, 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 downwind side lift vane is affected by the wake of the upwind side lift vane and the vortex created by the nacelle and struts. In this case, the power generation device has a mechanism for generating electric power through a differential gear (differential gear) which is one of differential devices and then connected to a speed increaser. The other patent document 2 is a type in which the lift blades on the upwind side and the downwind side sandwiching the nacelle rotate in the reverse direction on the same axis (hereinafter referred to as “coaxial reversal”). 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 rotational driving forces 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. Patent Document 2 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. As described, when the rotational driving force is mechanically extracted, whether the rotation is in the same direction or the coaxial reversal, the number of rotations of the output shaft is substantially the same as that of a pair of lift blades, or The speed of the blades on the downwind side becomes a brake, which is slower than the case of one set, and the reason that the speed increaser is not necessary only by using two sets of lift blades with coaxial reversal constitutes the reason It is not possible. In addition, although the differential gear (differential gear) is used for the differential gear of patent documents 8, when a fluid coupling (torque converter) is used, even if it makes the number of connection of a blade more than two sets, as a differential gear It becomes possible to function.

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 the gap between the opposed working surfaces of the permanent magnet and the electromagnet is formed at the blade tip, it is essential to be able to cope with expansion due to centrifugal force and expansion / contraction due to temperature change. Even when the peripheral speed is used mechanically, a mechanism that is less affected by the expansion and contraction of the blades and rings due to centrifugal force and temperature change is adopted, or even if it is affected, the effect can be absorbed in the mechanism Is essential.

Patent Document 1 shows a mechanism for generating electric power by electromagnetically utilizing the peripheral speed, and the working surfaces of the electromagnet and the permanent magnet facing each other are installed in a direction parallel to the rotation axis. In addition, a bearing that maintains a constant gap between the working surfaces of the electromagnet and the permanent magnet 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. In this way, by using a bearing that supports only the adsorption force due to the magnetic force between the electromagnet and the permanent magnet as a load, the gap between the electromagnet and the permanent magnet is, for example, 1 mm without being affected by centrifugal force or temperature change. A mechanism that can be held at all times is disclosed below.

Many examples of vertical axis wind turbines have generators installed at the root (foundation) of the wind turbine, but many horizontal axis wind turbines have generators installed in the nacelle. Among them, Patent Literature 3, Patent Literature 4 and Patent Literature 6 extract the rotational driving force from the rotational shaft at the center of rotation of the windmill, but the output direction of the rotational shaft is generally changed via a bevel gear or a differential device. 90 ° conversion is made so that the generator can be installed at any place in the middle part or base part (foundation part) of the column. For this reason, not only the size and shape of the generator can be selected, but also a plurality of generators are built in the column as in Patent Document 6, and the centrifugal clutch and electromagnetic clutch are used to connect and disconnect according to the wind speed. By adjusting the number of generator connections, the cut-in wind speed can be lowered to increase the cut-out wind speed. However, although patent document 3 has described as a claim with having dropped the generator from the nacelle and installed in the base part (foundation part) vicinity of a windmill, the generator is described as a root part (foundation part) of a windmill. It is a well-known matter that the installation in the vicinity has been done since the time of Paul La Cour, and is also disclosed in Patent Literature 6 and Patent Literature 9.

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 Documents 5 and 7 attempt to stabilize by attaching a flywheel to the rotating shaft of the windmill.

Due to the gyro precession of the stress in the left-right direction when a horizontal axis windmill with a ring that connects the blade tips and obtains the driving force to rotate the generator from the ring that rotates together with the blades turns upwind It is a problem to prevent power transmission from becoming unstable due to the contact / separation of the contact portion of the driving force transmitting portion due to the swinging phenomenon of the driving force transmitting portion coming from the 90 ° delay in the elevation direction.

In the present invention, a method for mechanically extracting the peripheral speed from the ring connecting the blade tips of the horizontal axis wind turbine and utilizing it as a driving force for rotating the generator is pursued. For this reason, when a horizontal axis wind turbine having an annulus that obtains a driving force for rotating a generator from an annulus that connects the blade tips and rotates together with the vane rotates in the windward direction, a gyro of stress in the left-right direction In order to prevent power transmission from becoming unstable due to separation of the abutting portion of the driving force transmission part due to a swinging phenomenon in the elevation direction of the driving force transmission part resulting from a 90 ° delay due to precession, two means Prepare and deal with it. First, as a common means, on the rotating shaft that supports the wind turbine so as to be rotatable, at least one front side of the extension surface of the front side surface of the ring and one rear side of the extension surface of the rear side surface of the ring. It has a total of two or more bearings and supports it firmly to suppress the wind turbine from swinging up and down, and as a first means, it has a rotation axis in a direction perpendicular to the rotation axis of the ring, Two or more rotating shafts are provided by providing a roller sandwiched from both sides and a joint device on the path for guiding the driving force obtained by the roller to the generator to cope with the expansion and contraction of the shaft and the bending of the shaft. To cope with the deflection in the up-and-down direction as the deflection of the whole horizontal axis wind turbine, which is inevitable even if it is reinforced with the bearings of the bearing and firmly supported. Further, as a second means, there is an annular ring having an outer peripheral shape that swells outward, and a tire that has a rotation axis parallel to the rotation axis of the ring and abuts on the outer periphery of the ring. By providing it in combination, it is possible to cope with the deflection in the elevation direction as the deflection of the entire horizontal axis wind turbine that cannot be avoided even if the rotating shaft is reinforced with two or more bearings and firmly supported. In addition, a part of the material of the annulus and the roller or tire that contacts the annulus may be made of rubber, synthetic resin, silicon, or other material that can absorb the effects of expansion and contraction, or the inside of the annulus. This is dealt with by filling the hollow part with high-pressure gas or liquid so that the degree of contact with the roller or tire can be adjusted.

Up to now, when turning in the direction of the wind of a horizontal axis wind turbine, the stress in the left-right direction is delayed by 90 °, resulting in a swing in the up-and-down direction. Therefore, a normal propeller type wind turbine in which individual propellers respond to the swing by releasing the blade tip Unlike the case described above, in the wind turbine in which the blade tips are connected by a heavy ring, the peripheral speed of the wind turbine has become an obstacle to take out mechanically. However, by using either the first means or the second means of the present invention, the peripheral speed of the blades of the horizontal axis windmill can be mechanically and stably taken out even if the horizontal axis windmill turns upwind. . Therefore, if the peripheral speed of the horizontal axis wind turbine can be stably taken out and connected to the rotating shaft of the generator, the generator can be rotated at a high speed, so that a high rotational speed can be easily given to the generator without using a speed increaser. And efficient power generation. Further, in the present invention, since the outer periphery of the blade is always covered with an annulus and rotates together with the blade, there is also an effect of a flywheel due to the weight of the annulus. It can also contribute to the improvement of power quality.

In the first means, the present invention is usually composed of 10 to 11 main parts. That is, when the blades of a horizontal axis wind turbine are a pair, at least one front side of the extension surface of the front side surface of the ring and one rear side of the extension surface of the rear side surface of the ring. Rotating shaft (110) having a bearing (111) that rotatably supports the wind turbine, drag blades (210) and lift blades (220), and blades that serve as pedestals for blades attached to the inner periphery of the ring (310) An end fitting (230), a ring (310) that connects the blade tips of the blades and rotates with the blades to generate a driving force, and a rotation axis that is orthogonal to the rotation axis of the ring (310) The roller (410) that comes into contact with both sides of the ring to obtain driving force, and the ring (310) are turned in different directions by coming into contact with both sides of the ring (310) from both sides. The rotational force of two rollers can be combined into one gear A gear device (510) that outputs power, a joint device (610) for coping with shaft expansion and contraction and shaft bending when the wind turbine swings on the path for driving force, too low wind speed and intensity A clutch device (810) for connecting the drive shaft between the cut-in wind speed and the cut-out wind speed by disconnecting the drive shaft when the wind speed is too high, and a turning device (910) for causing the horizontal axis wind turbine to face the wind, It is the generator (1000) installed near the base part (foundation part) of a windmill. When there are two or more sets of horizontal axis wind turbine blades, a differential device (710) is added to the above main components.

The second means of the present invention is usually composed of 8 to 10 main parts. That is, when the blades of a horizontal axis wind turbine are a pair, at least one front side of the extension surface of the front side surface of the ring and one rear side of the extension surface of the rear side surface of the ring. Rotating shaft (110) having a bearing (111) that rotatably supports the wind turbine, drag blades (210) and lift blades (220), and blades that serve as a base for blades attached to the inner periphery of the ring (320) An end fitting (230), an annular ring (320) that connects the blade tips of the blades and rotates together with the blades to generate a driving force and forms an arc shape in which the shape of the outer periphery swells outward; 320) having a rotation axis parallel to the rotation axis and abutting on the outer periphery of the ring to obtain driving force, and disconnecting the driving shaft when the wind speed is too low or too high. The drive shaft is connected between the cut-in wind speed and the cut-out wind speed. A clutch device (810) capable of adjusting the number of connected machines, a turning device (910) for causing a horizontal axis wind turbine to face the wind, and a generator (1000) sharing a rotating shaft with a tire (420). . In the case where the generator (1000) is installed near the root (base) of the horizontal axis wind turbine, a bevel gear (520) is added. Further, when there are two or more sets of blades of a horizontal axis wind turbine, a differential device (710) is also added to the above main components.

In the present invention, a ring ((310), (320)) is always used. For this reason, the drag blade (210) and the lift blade (220) do not necessarily have to connect the blade center (blade root) to the rotating shaft (110), but via the blade tip fitting (230) serving as a blade base. It can be installed on the inner periphery of the ring ((310), (320)). In addition, the wing tip fitting (230) can easily correct the angle of attack of the blade at any time during maintenance or the like, and also has an angle-of-attack change gear (241) for changing the angle of attack and an angle-of-attack change motor ( 242) and the angle-of-attack changing worm gear (243), the angle of attack can be changed at any time even during rotation of the windmill, and automation is also possible.

Beams (360) and spokes (370) connecting the rings ((310), (320)) and the rotating shaft (110) are the tip of the drag blade (210) and lift blade (220) attached to the horizontal axis wind turbine. Is connected to the inner periphery of the ring ((310), (320)), and the blade center (blade root) is not connected to the rotating shaft (110). Therefore, it is not necessary when the blade core (blade root) is connected to the rotating shaft (110) as in a conventional horizontal axis wind turbine.

In order to generate power efficiently with a horizontal axis windmill, it is necessary to turn to face upwind. At this time, since the propeller type generally used in the horizontal axis wind turbine releases the blade tip, the stress in the left-right direction when the horizontal axis wind turbine turns is delayed by 90 ° due to the gyro precession, Even if it becomes stress, since the blades bend individually and release the force, the influence on the entire wind turbine is small. However, in the horizontal axis wind turbine of the present invention, the wing tips are connected by heavy rings ((310), (320)), so that every time the direction is changed, a strong stress in the elevation direction is applied to the entire horizontal axis wind turbine. appear. For this reason, a horizontal axis windmill cannot be supported only from one of the rear (up window type) and the front (down window type) as seen in a normal propeller type. For this reason, the rotating shaft (110) used in the present invention has a rotating shaft length that is at least longer than the width (340) of the annular ring, and a total of two at least one near each end of the rotating shaft (110). Having the above bearing (111), it firmly supports the horizontal axis wind turbine. Particularly when the horizontal axis wind turbine becomes huge, it is necessary to support the rotating shaft with four, six or more bearings.

Thus, even if the rotating shaft of the horizontal axis wind turbine is firmly supported, the horizontal stress at the time of turning becomes the stress in the elevation direction, resulting in deflection of the ring ((310), (320)) portion of the horizontal axis wind turbine. , The roller (410) and the tire (420) are brought into contact with the lowermost part of the ring ((310), (320)), and the driving force transmission part for taking out the driving force is shaken to cause the contact part to be separated and connected. This becomes an unstable factor when the circumferential speed of the ring ((310), (320)) is used as the driving force. In order to prevent this instability, in the first means, first, the roller (410) that contacts the ring (310) is used so as to sandwich the ring (310) from both side surfaces in order to obtain driving force. In addition, a joint device (610) consisting of a combination of a free wire, a combination of a slide shaft and a ball joint, or a combination of a slide shaft and a cross joint is interposed in the middle of connection to a generator near the base (base) of a horizontal axis wind turbine. Therefore, the driving force can be stably transmitted, so that even if the ring ((310), (320)) is swung, the contact portion is prevented from being separated and connected, and the transmission of the driving force can be stabilized. In the second means, the shape of the outer periphery of the ring (320) is an arc that bulges outward, and the shape of the outer periphery of the ring (320) is used for some blurring. Since it can cope so that a contact part may not remove | deviate, transmission of a driving force can be stabilized. However, in the case of a large-diameter horizontal axis wind turbine that generates both large expansion and contraction and large runout that cannot be dealt with only by the circular arc shape of the outer periphery of the ring (320), the tire (420) portion is It is mounted on a suspension device (930) capable of handling large expansion and contraction and slight vibration.

The driving force thus obtained is connected to the generator (1000) via the clutch device (810). When the rotational force of the windmill is too weak to start power generation, the clutch device (810) disconnects the generator that becomes a load until the rotational speed of the windmill reaches a certain speed, and vice versa. If the rotation speed of the windmill is too fast to burn the generator coil, disconnect the connection and connect the drive shaft when the wind speed exceeds the cut-in wind speed and is within the cut-out wind speed. By adjusting the number of connections, the power generation range can be widened. The clutch device (810) includes, for example, a centrifugal clutch that mechanically separates and connects with the magnitude of centrifugal force, and an electromagnetic clutch that electrically connects and disconnects from external wind speed and wind measurement data. Is possible.

There is a turning device (910) in the vicinity of the root part (foundation part) of the horizontal axis windmill, and the horizontal axis windmill can face the windward. In addition to measuring the wind direction with another device and directing it in that direction with human power or an electric motor, in addition to applying a cone angle to the blade as shown in FIG. If the center line of the horizontal axis wind turbine is installed on the leeward side behind the rotation center point of the turning device (910) in addition to the cone angle as shown in FIG. Demonstrate. Further, in order to obtain a greater force for turning from the wind, as shown in FIG. 59, a tail feather telescopic arm (122) is provided along the rotation axis (110), and a tail feather (122) is attached to the tip of the tail feather telescopic arm (122). 121), the horizontal axis wind turbine can be automatically faced upwind by the wind force. The tail feather (121) can be adjusted in length by the tail feather telescopic arm (122), so that the force of turning can be adjusted, and in strong winds, it can be tilted near the root (base) of the windmill to avoid unnecessary turning. You can also. However, when the horizontal axis wind turbine turns in small increments by using the tail feather (121) having a strong force directly facing the windward, it is not preferable because the power transmission part is shaken. Therefore, when using the tail feather (121), a turning device (910) that can smooth the turning force by incorporating an oil damper or the like for restricting turning is used.

When there are two sets of wind turbine blades, the rotational speeds of the windmill in the windward direction (hereinafter referred to as “front windmill”) and the windmill in the windward direction (hereinafter referred to as “rear windmill”) are different. One output is output as the only driving force through the differential device (710), and is connected to the generator (1000) to generate power. Similarly, when a plurality of wind turbines having an annular shape are sandwiched between the front wind turbine and the rear wind turbine, the driving force is taken out through the differential device (710) and connected to the generator (1000).

The wind turbine of the present invention has a small number of parts, a simple structure, and does not require high accuracy during assembly. For this reason, disassembly, conveyance, and reassembly are easy. Therefore, a device (cloth placement device) that allows an object to be placed along the shape of the ground without digging a hole as in the case of placing a cloth as shown in FIG. 60 (C) on the ground.
