DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic perspective view for explaining an embodiment of the present invention, a wind power generator utilizing wind. FIG. 2 is a schematic front view showing a state where one embodiment of the present invention is attached to a holding frame. In FIGS. 1 and 2, the output rotary shaft 11 is rotatably held by a self-aligning ball bearing 12 for holding the output rotary shaft and a thrust bearing 13. The output rotary shaft 11 is mounted such that, for example, the cross-shaped lower arm 14 and the parallel-shaped cross-shaped upper arm 141 are integrally rotated. Below the thrust bearing 13, a self-aligning radial bearing 15 for applying a radial load of the output rotary shaft 11 is provided. Further, a pulley 16 is attached to a lower end of the output rotary shaft 11, and is connected to, for example, a power generator 18 via a belt 17. The self-aligning ball bearing 12 for holding the output rotary shaft is
It is attached to the upper holding frame 312 (see FIG. 2).
Further, the thrust bearing 13 and the self-aligning radial bearing 15 are connected to a lower holding frame 313 (see FIG. 2).
Attached to. The upper holding frame 312 and the lower holding frame 313 constitute the holding frame 31 together with the vertical holding frame 311 and hold the wind turbine generator. The output rotation shaft 11 is connected to the output rotation shaft 1 via a pulley 16 or the like.
1 energy can be extracted.

The curved blade 21 has a curved surface with a large radius of curvature, is made of a single plate material symmetrical with respect to a vertical center line, and is fixed to a rotatable center shaft 211.
The center shaft 211 is connected to the cross-shaped lower arm 1.
4 and a cross-shaped upper arm 141 which is rotatable by the bearing 212. That is, when the four curved blades 21 shown in FIG. 1 receive wind pressure from one side, the concave surface portion receives a higher pressure than the convex surface portion according to Bernoulli's theorem. To the left. The output rotary shaft 11 is rotatably attached to the upper holding frame 312 via the above-described self-aligning ball bearing 12, a thrust bearing 13, and a self-aligning radial bearing 15 for holding the output rotary shaft. The wind direction adjusting upper spur gear 22 and the wind direction adjusting lower spur gear 23 are integrally formed and rotatably attached to the output rotary shaft 11.

The wind direction adjusting upper spur gear 22 has the same central axis as the output rotation shaft 11 integrally with the rotation torque generation execution angle control gear 25, and can freely rotate around the output rotation shaft 11. This is for automatically controlling the position of the wind direction by the wind direction rudder 223, and the angle of the wind direction rudder 223 is transmitted via the spur gear 221 for reversing the wind direction angle and the upper spur gear 222 for transmitting the wind direction angle. In the wind rudder 223, a weight 224 having a time constant for preventing the wind direction of the wind from frequently changing is attached in the opposite direction. Also,
The wind rudder 223 is provided with a wind direction angle adjusting unit 225 that can be bent to a desired angle by a screw or the like in the middle. The wind direction angle adjusting unit 225 can adjust the wind pressure applied to the curved blade 21 from the maximum to the minimum by changing the angle between the wind rudder 223 and the weight 224 from 0 degree to 90 degrees. Therefore, when using the device of the present embodiment for wind power generation, a typhoon or strong wind is known in advance by a weather forecast,
The angle of the wind direction adjusting unit 225 is adjusted in accordance with the expected wind speed so that the rotation speed of the curved blade 21 is not too fast.
When the apparatus of this embodiment is used as an advertising medium or a display medium, the wind direction angle is adjusted so that the rotation speed of the curved blade 21 becomes a desired speed in consideration of the expected wind speed and the displayed content. The angle of the adjusting unit 225 is adjusted. Further, the wind direction angle adjustment section 225 can also make it possible to remotely control the angle adjustment.

The wind direction adjusting lower spur gear 23 has the same central axis as the output rotating shaft 11 integrally with the wind direction adjusting upper spur gear 22, and can freely rotate around the output rotating shaft 11. , Four intermediate rotation spur gears 24 for reversing the rotation angle
Is surrounding. Four intermediate rotation spur gears 2 for reversing the rotation angle
4 are in mesh with the rotational torque generation execution angle control gear 25, respectively. The number of teeth of the lower spur gear 23 for adjusting the wind direction and the number of teeth of the intermediate spur gear 24 for reversing the rotation angle and the number of teeth of the rotation torque generation execution angle control spur gear 25 are 1: 2. The rotation torque generation execution angle control gear 25 has a pivot 26 provided on a part of the surface of the execution angle control gear. The number of teeth of each of the intermediate gears can be arbitrarily selected. In the pivot 26,
The crank rod 27 can rotate on the upper surface of the rotational torque generation execution angle control gear 25 about the pivot 26. The other end of the crank rod 27 is rotatably joined to the vertical direction via a pivot pin 29 of a hook crank 28. The other of the hook-shaped cranks 28 is provided on a cross-shaped upper arm 141, is rotatable by a bearing 212, and is joined to a center shaft 211 of the curved blade 21.

FIG. 3 is a view for explaining rotation of a curved blade by a crank mechanism and a gear mechanism according to an embodiment of the present invention. FIG. 4 is a view for explaining the angle of each curved blade when the wind direction angle is 0 in the embodiment of the present invention. In FIG. 3, unlike the embodiment of FIG. 1, the curved blade 21 has a thicker center in cross section, a thinner streamline toward the end, a larger radius of curvature, and a center of the circle in the opposite direction. An example is shown. In FIG. 3, the curved blade 21 receives wind from the right angle direction W. At this time, the curved blade 21 feels the wind pressure on both the flat portion and the convex portion, but has a property of rotating leftward about the central axis 211 according to Bernoulli's theorem.

The curved blade 21 starts rotating around the central axis 211 by the left rotation by the wind. The rotation of the curved blade 21 is performed by a hook-shaped crank 28, a crank rod 27,
The left rotation is stably performed by the rotation torque generation execution angle control gear 25. The wind pressure on the flat surface portion and the convex surface portion of the curved blade 21 causes clockwise rotation about the output rotation shaft 11 fixed to the cross-shaped lower arm 14 and the cross-shaped upper arm 141. For example, four curved blades 21
Are turned 45 degrees each, and one is installed in a state that receives the maximum wind pressure and receives the minimum wind pressure on the opposite side, and is controlled by the rotational torque generation execution angle control gear 25, On the average, the right rotation torque of the output rotation shaft 11 can be constantly maintained. Conversely, one of the four curved blades 21 receives the minimum wind pressure, and the other side receives the uniform wind pressure on the left and right sides of the curved blade 21 on the opposite side, and the other two curved blades 21 mutually output rotation shafts. If the right rotation torque of the output rotation shaft 11 is canceled, the right rotation torque of the output rotation shaft 11 cannot be obtained.

The curved blade 21 generates a rotational torque by a gear mechanism including a wind direction adjusting lower spur gear 23, a rotation angle reversing intermediate spur gear 24, a rotational torque generation execution angle control gear 25, a crank rod 27, and the like, and a crank mechanism. The corner is controlled. When receiving the wind, the curved blades 21 always rotate counterclockwise according to Bernoulli's theorem, thereby assisting the rotation control energy of the rotation torque generation execution angle control gear 25. The rotational torque generation angle (α) due to the wind pressure at a certain position of the curved blade 21 = 90 ° + wind direction angle (β) + [rotation angle (γ) of output rotation shaft] / 2. However, 0 degree of the rotation torque generation angle (α) is from 0 o'clock of the clock, and 0 degree of the output rotation axis is 3 o'clock of the clock. The number of teeth of the rotation angle reversing intermediate spur gear 24 and the rotation torque generation execution angle control gear 25 is 1: 2.

In FIG. 3, for example, the rotational torque generation angle (α) is maximum when the wind W is 90 degrees and 270 degrees, and is minimum when it is 0 degrees and 180 degrees. Also,
According to the above equation, when the rotation angle (γ) of the output rotation shaft is 45 degrees, the rotation torque generation angle (α) = 90 degrees + (β) + (γ)
/2=90+45/2=112.5 degrees. However,
The wind direction angle (β) was assumed to be constant. The number of teeth of the lower spur gear 23 for adjusting the wind direction, the intermediate spur gear 24 for reversing the rotation angle, and the rotation torque generation execution angle control gear 25 is 1: 2. Therefore, as can be seen from FIG. 4, the curved blade 21 has only one half rotation while the output rotation shaft 11 makes one rotation.

Returning to FIG. 1, the automatic follow-up correction mechanism when the wind direction (arrow W) changes will be described. In FIG. 1, the wind direction angle automatic follow-up correction mechanism includes, for example, a wind direction adjusting upper spur gear 22, a wind direction angle reversing spur gear 221, a wind direction angle transmitting upper spur gear 222, a wind direction rudder 223, and a weight 22.
4, and a wind direction angle adjustment unit 225. For example, if the wind direction changes to the left,
Wind direction angle transmission upper spur gear 222-Wind direction angle reversal spur gear 2
21-upper spur gear 22 for wind direction adjustment-lower spur gear 23 for wind direction adjustment-intermediate spur gear 24 for reversing rotation angle-rotation torque generation execution angle control gear 25
By using 8, the direction of the curved blade 21 is corrected to a desired direction. In the equation in the above paragraph, (β) indicates that the wind direction
Is zero in the W direction, and changes to the left (negative), so that the central axis 211 of the curved blade 21 is corrected so as to rotate further to the left. When the wind direction angle (β) changes rightward (positive), the wind direction angle (β) becomes the center axis 2 of the curved blade 21.
11 is further rotated clockwise.

For example, when the wind direction changes rightward, the wind rudder 223 turns slightly rightward. Due to this rotation, the wind direction transmission upper spur gear 222 also rotates clockwise. By this rotation, the wind direction angle reversing spur gear 2
21 rotates leftward. Similarly, the wind direction adjusting upper spur gear 22 and the wind direction adjusting lower spur gear 23 rotate clockwise, the rotation angle inverting intermediate spur gear 24 turns left, the rotational torque generation execution angle control gear 25 turns right, and The central shaft 211 rotates leftward. That is,
When the wind direction is rightward, the curved follower 21 can be rotated leftward and corrected by the automatic follow-up correction mechanism.

In FIG. 1, it is assumed that the wind rudder 223 blows a constant wind in the direction of the arrow W shown in FIG. The wind direction angle transmitting upper spur gear 222, the wind direction angle reversing spur gear 221, the wind direction adjusting upper spur gear 22, and the wind direction adjusting lower spur gear 23 have a constant position without rotating. The upper right curved blade 21 in FIG. 1 receives the maximum wind pressure, rotates by Bernoulli's theorem, and applies the maximum rotational torque to the cross-shaped lower arm 14 and the cross-shaped upper arm 141. Since the lower left curved blade 21 in FIG. 1 has substantially the same direction of the wind, it obtains a slight wind pressure on the curved surface and has a considerable amount of rotation, but the cross-shaped lower arm 14 and the cross-shaped upper arm 1
No rotational torque is applied to 41. Since the lower right and upper left curved blades 21 in FIG. 1 have a predetermined angle, they receive a predetermined wind pressure, rotate, and apply a rotational torque to the cross-shaped lower arm 14 and the cross-shaped upper arm 141.

From the rotational torque generation execution angle control gear 25,
Controlled by a hook-shaped crank 28 and a crank rod 27,
The curved blade 21 rotates around the wind direction adjusting lower spur gear 23 while rotating. FIG. 4 shows the rotating state of each curved blade 21.

Here, when the wind direction changes, the wind direction rudder 22
By changing the direction of 3, the wind direction angle transmission upper spur gear 222, wind direction angle reversal spur gear 221, and wind direction adjustment upper spur gear 22 are transmitted. That is, the direction of the wind direction adjusting upper spur gear 22 is transmitted to the wind direction adjusting lower spur gear 23, and the rotation torque generation execution angle of each curved blade 21 is corrected, so that each curved blade 21 has the maximum efficiency. Wind pressure. The wind rudder 223 is, for example,
At 25, after loosening the screw, turn 90 degrees and retighten the screw. Thereby, the direction of the wind direction adjusting upper spur gear 22 is changed by 90 degrees, and each curved blade 21 is a curved blade 21 to which wind pressure is not applied, a curved blade 21 to which wind pressure is applied on both sides of the center on average, The curved blades 21 cancel each other out of the wind pressure, and even if each of them rotates, no rotation torque is applied to the output rotation shaft 11. The wind direction angle adjustment unit 225 can be adjusted manually, automatically, remotely, or the like. Further, the upper spur gear 22 for transmitting the wind direction angle
2, the arrangement of the wind direction angle reversal spur gear 221, the wind direction adjustment upper spur gear 22, the wind direction angle adjustment unit 225, the wind direction rudder 223, and the like can be located below the holding frame 31. In the above case, especially when the adjustment of the wind direction angle adjustment unit 225 is manual, the adjustment can be performed at a low position.

The curved blade 21 rotates and revolves,
It can be used as an advertising medium or a display medium as well as a power generator or other energy converter.
In particular, since the rotation of the curved blade 21 and the rotation of the output rotary shaft 11 are slow, as an advertising medium and a display medium,
It is easy to see and can be seen from a distance even if it is large.

Although the embodiments of the present invention have been described in detail, the present invention is not limited to the above embodiments. And
The present invention is capable of various design changes without departing from the scope of the claims. Although the components, materials, and their mounting structures in the present embodiment are not described in detail, well-known or known components or means can be employed. In particular, for the curved blade, any of a plastic and a metal plate can be used, and integral molding, sheet metal processing, and other processing means can be adopted. In addition, off-the-shelf products can be used for the gears or the crank mechanism. The number, size, etc. of the curved blades can be arbitrarily increased or decreased by design.

[0046]

According to the present invention, the rotation torque generation execution angle of the curved blade is controlled by a simple gear mechanism and a crank mechanism using the left rotating torque of the curved blade according to Bernoulli's theorem. High rotational torque can be obtained. Further, since the mechanism of the present invention rotates at a low speed, even if the mechanism becomes large, a safe and robust structure can be achieved. According to the present invention, by providing the automatic follow-up correction mechanism, efficient operation can be performed in accordance with the expected wind speed, and therefore, safety is provided. According to the present invention, expensive parts such as propellers are not required, and the tower is not required to support them, so that the production cost is low.

In the above-mentioned conventional energy conversion device, since the chain is arranged in the horizontal direction, the chain is slackened by its gravity, so that the chain needs to be constantly repaired and the mechanically smooth rotation. The question is whether it can be done. Further, since the blade is a flat surface, the rudder may not be able to maintain a correct wind direction, for example, due to the co-rotation of the rudder due to the weight friction of the fixed shaft and the friction of the chain and the like. In addition, there is a problem that a loss of a transmission mechanism such as a chain is large due to insufficient rotation torque of the blade. JP 54

2. Description of the Related Art Conventionally, wind power generation has been used to convert wind energy into rotational energy. In the wind power generation, a power generator is driven by rotating a propeller using wind.

As an inexpensive wind power generator that does not use a propeller, for example, Japanese Unexamined Patent Application Publication No. 10-4722
There is an energy conversion device described in Japanese Patent No. The technology described in the above publication includes a blade rotation consisting of a plane receiving a wind, and an output shaft revolving in the same direction as the rotation direction of the blade. The rotation of the blade is transmitted by a chain and a gear mechanism. ing.

Trying to get.

[0004]

In the above-mentioned conventional energy conversion device, since the chain is arranged in the horizontal direction, the chain is slackened by its gravity, so that repair and the like are always required, and mechanically smooth rotation is required. The question is whether you can do it. Further, since the blade is a flat surface, the rudder may not be able to maintain a correct wind direction, for example, due to the co-rotation of the rudder due to the weight friction of the fixed shaft and the friction of the chain and the like.

[0005] Further, there is a problem that a loss of a transmission mechanism such as a chain is large due to insufficient rotation torque of the blade. JP-A-54-35544 and JP-A-56-56544

FIG. 2 is a schematic front view showing a state where one embodiment of the present invention is attached to a holding frame. In FIGS. 1 and 2, the output rotary shaft 11 is rotatably held by a self-aligning ball bearing 12 for holding the output rotary shaft and a thrust bearing 13. The output rotary shaft 11 is mounted such that, for example, the cross-shaped lower arm 14 and the parallel-shaped cross-shaped upper arm 141 are integrally rotated. Below the thrust bearing 13, a self-aligning radial bearing 15 for applying a radial load of the output rotary shaft 11 is provided.

Further, a pulley 16 is attached to a lower end of the output rotary shaft 11, and is connected to, for example, a power generator 18 via a belt 17. The self-aligning ball bearing 12 for holding the output rotary shaft is attached to an upper holding frame 312 (see FIG. 2). The thrust bearing 13 and the self-aligning radial bearing 15
Is attached to the lower holding frame 313 (see FIG. 2). The upper holding frame 312 and the lower holding frame 313 are
The holding frame 31 is configured together with the vertical holding frame 311 to hold the wind turbine generator. The output rotary shaft 11 can extract the energy of the output rotary shaft 11 via a pulley 16 or the like.

The curved blade 21 is formed of a curved surface having a large radius of curvature, and is formed of an arc having a radius of curvature larger than the width in a direction opposite to the longitudinal center line,
It is made of a plate member having the same cross-sectional thickness and is fixed to a rotatable center shaft 211. The center shaft 211 is rotatably configured by a bearing 212 provided on the cross-shaped lower arm 14 and a cross-shaped upper arm 141 provided on the cross-shaped upper arm 141. That is, the four curved blades 21 shown in FIG.
When receiving wind pressure from one side, the concave portion receives a higher pressure than the convex portion according to Bernoulli's theorem. Can be.

The output rotary shaft 11 is rotatably mounted on the upper holding frame 312 via the above-described self-aligning ball bearing 12, thrust bearing 13, and self-aligning radial bearing 15 for holding the output rotary shaft. The wind direction adjusting upper spur gear 22 and the wind direction adjusting lower spur gear 23 are integrally formed and rotatably attached to the output rotary shaft 11.

The wind direction adjusting upper spur gear 22 has the same central axis as the output rotating shaft 11 integrally with the wind direction adjusting lower spur gear 23, and can freely rotate around the output rotating shaft 11. This is for automatically controlling the wind direction position by the wind direction rudder 223, and the wind direction rudder 22 is transmitted through the wind direction angle reversing spur gear 221 and the wind direction angle transmitting upper spur gear 222.
An angle of 3 is transmitted.

On the wind rudder 223, a weight 224 having a time constant for preventing the wind direction of the wind from frequently changing is mounted in the opposite direction. Further, the wind direction rudder 223 is provided with a wind direction angle adjusting unit 225 that can be bent to a desired angle with a screw or the like in the middle. Wind direction adjustment unit 225
By changing the angle between the wind rudder 223 and the weight 224 from 0 degrees to 90 degrees, the wind pressure applied to the curved blade 21 can be adjusted from the maximum to the minimum.

Therefore, when the apparatus of this embodiment is used for wind power generation, a typhoon or a strong wind is known in advance by a weather forecast, and the wind direction angle is adjusted in accordance with the expected wind speed so that the rotation speed of the curved blade 21 is not too fast. The angle of the adjusting unit 225 is adjusted. When the apparatus of this embodiment is used as an advertising medium or a display medium, the wind direction angle is adjusted so that the rotation speed of the curved blade 21 becomes a desired speed in consideration of the expected wind speed and the displayed content. The angle of the adjusting unit 225 is adjusted. Further, the wind direction angle adjusting unit 225 can also be the angle adjustment to Ru can remotely.

The wind direction adjusting lower spur gear 23 has the same central axis as the output rotating shaft 11 integrally with the wind direction adjusting upper spur gear 22, and can freely rotate around the output rotating shaft 11. , Four intermediate rotation spur gears 24 for reversing the rotation angle
Is surrounding. Four intermediate rotation spur gears 2 for reversing the rotation angle
4 are in mesh with the rotational torque generation execution angle control gear 25, respectively. The number of teeth of the wind direction adjusting lower spur gear 23 and the number of teeth of the rotation angle inverting intermediate spur gear 24 and the number of teeth of the rotation torque generation execution angle control gear 25 are 1: 2. The rotation torque generation execution angle control gear 25 has a pivot 26 provided on a part of the surface of the execution angle control gear. The number of teeth of each intermediate gear is
It can be arbitrarily selected.

On the pivot 26, a crank rod 27 is provided with a rotational torque generation execution angle control gear 25 around the pivot 26.
Can be turned on the upper surface. The other end of the crank rod 27 is rotatably joined to the vertical direction via a pivot pin 29 of a hook crank 28. The other of the hook-shaped cranks 28 is provided on a cross-shaped upper arm 141, is rotatable by a bearing 212, and is joined to a center shaft 211 of the curved blade 21. The rotation torque generation execution angle control gear 25 and the crank mechanism generate a torque for rotating the output rotation shaft 11 for a reason described later.

FIG. 3 is a view for explaining rotation of a curved blade by a crank mechanism and a gear mechanism according to an embodiment of the present invention. FIG. 4 is a view for explaining the angle of each curved blade when the wind direction angle is 0 in the embodiment of the present invention. In FIG. 3, unlike the embodiment of FIG. 1, the curved blade 21 has a flat surface on one surface, a thick center portion and a thin end portion on the other surface, and is line-symmetric with respect to the vertical center line. It has become.
In FIG. 3, the curved blade 21 receives wind from the right angle direction W. At this time, the curved blade 21 feels wind pressure on both the flat portion and the convex portion, but has a property of rotating leftward about the central axis 211 by Bernoulli's theorem.

The curved blade 21 starts to rotate around the central axis 211 by left rotation (counterclockwise rotation) by wind. The rotation of the curved blade 21 stably generates a left-rotating torque by the hook-shaped crank 28, the crank rod 27, and the rotation torque generation execution angle control gear 25. The wind pressure on the flat surface portion and the convex surface portion of the curved blade 21 causes clockwise rotation about the output rotation shaft 11 fixed to the cross-shaped lower arm 14 and the cross-shaped upper arm 141.

For example, when the four curved blades 21 are mounted in such a manner that each of them is turned 45 degrees and one of them receives the maximum wind pressure and the other receives the minimum wind pressure on the opposite side, the rotational torque is increased. Controlled by the generation execution angle control gear 25, the right rotation torque of the output rotation shaft 11 can be constantly maintained on average. Conversely, one of the four curved blades 21 receives the minimum wind pressure, the other receives the uniform wind pressure on the left and right sides of the curved blade 21 on the opposite side, and the other two
When the curved blades 21 are at positions where the right rotation torque of the output rotation shaft 11 cancels each other, the right rotation torque of the output rotation shaft 11 cannot be obtained.

The curved blade 21 generates a rotational torque by a gear mechanism including a wind direction adjusting lower spur gear 23, a rotation angle reversing intermediate spur gear 24, a rotation torque generation execution angle control gear 25, a crank rod 27, and the like, and a crank mechanism. The corner is controlled. When receiving the wind, the curved blades 21 always rotate counterclockwise according to Bernoulli's theorem, thereby assisting the rotation control energy of the rotation torque generation execution angle control gear 25.

Rotational torque generation angle (α) due to wind pressure at a certain position of curved blade 21 = 90 degrees + wind direction angle (β) +
[Rotation angle (γ) of output rotation shaft] / 2. However, 0 degree of the rotation torque generation angle (α) is from 0 o'clock of the clock, and 0 degree of the output rotation axis is 3 o'clock of the clock. Intermediate spur gear 24 for rotation angle reversal and rotational torque generation execution angle control gear 2
The number of teeth with 5 is 1: 2.

In FIG. 3, for example, the rotational torque generation angle (α) is maximum at 90 ° and 270 ° with respect to wind W, and minimum at 0 ° and 180 °. Also,
According to the above equation, when the rotation angle (γ) of the output rotation shaft is 45 degrees, the rotation torque generation angle (α) = 90 degrees + (β) + (γ)
/2=90+45/2=112.5 degrees. However,
The wind direction angle (β) was assumed to be constant.

The lower spur gear 23 for adjusting the wind direction, the intermediate spur gear 24 for reversing the rotation angle, and the rotation angle control gear 2
The number of teeth with 5 is 1: 2. Therefore, as can be seen from FIG. 4, the curved blade 21 has only one half rotation while the output rotation shaft 11 makes one rotation.

Returning to FIG. 1, the automatic follow-up correction mechanism when the wind direction (arrow W) changes will be described. In FIG. 1, the wind direction angle automatic follow-up correction mechanism includes, for example, a wind direction adjusting upper spur gear 22, a wind direction angle reversing spur gear 221, a wind direction angle transmitting upper spur gear 222, a wind direction rudder 223, and a weight 22.
4, and a wind direction angle adjustment unit 225.

For example, when the direction of the wind changes to the left, the change of the wind direction is determined by the upper spur gear 222 for transmitting the wind direction angle, the spur gear 221 for reversing the wind direction angle, and the upper spur gear 22 for adjusting the wind direction.
Lower spur gear 23 for wind direction adjustment-intermediate spur gear 2 for rotation angle reversal
4- The torque is transmitted to the rotation torque generation execution angle control gear 25, and the direction of the curved blade 21 is corrected to a desired direction by the crank mechanisms 27 and 28.

In the equation in the above paragraph, (β) is 0 when the direction of the wind is the W direction in FIG. Is corrected. In addition, wind direction angle (β)
Is changed to the right (positive), and the curved blade 21
Is corrected so that the center axis 211 of the image is rotated clockwise.

For example, when the wind direction changes to the right, the wind rudder 223 turns slightly to the right. Due to this rotation, the wind direction transmission upper spur gear 222 also rotates clockwise. By this rotation, the wind direction angle reversing spur gear 2
21 rotates leftward. Similarly, the wind direction adjusting upper spur gear 22 and the wind direction adjusting lower spur gear 23 rotate clockwise, the rotation angle inverting intermediate spur gear 24 turns left, the rotational torque generation execution angle control gear 25 turns right, and The central shaft 211 rotates leftward. That is,
When the wind direction is rightward, the curved follower 21 can be rotated leftward and corrected by the automatic follow-up correction mechanism.

In FIG. 1, it is assumed that the wind rudder 223 blows a constant wind in the direction of the arrow W shown in FIG. The position of the upper spur gear 222 for transmitting the wind direction angle, the upper spur gear 221 for reversing the wind direction angle, the upper spur gear 22 for adjusting the wind direction, and the lower spur gear 23 for adjusting the wind direction are constant without being rotated by the wind in a certain direction. FIG.
The upper right curved blade 21 receives the maximum wind pressure, rotates by Bernoulli's theorem, and applies the maximum rotational torque to the cross-shaped lower arm 14 and the cross-shaped upper arm 141.

Since the lower left curved blade 21 in FIG. 1 has substantially the same direction of the wind, a slight wind pressure is obtained on the curved surface.
Although it has a considerable amount of rotation, it does not apply a rotating torque to the cross-shaped lower arm 14 and the cross-shaped upper arm 141. Since the lower right and upper left curved blades 21 in FIG. 1 are at a predetermined angle, they receive a predetermined wind pressure, rotate, and have the cross-shaped lower arm 14 and the cross-shaped upper arm 1.
41 is given a rotational torque.

From the rotational torque generation execution angle control gear 25,
Controlled by a hook-shaped crank 28 and a crank rod 27,
The curved blade 21 rotates around the wind direction adjusting lower spur gear 23 while rotating. FIG. 4 shows the rotating state of each curved blade 21.

Here, when the wind direction changes, the wind direction rudder 22
By changing the direction of 3, the wind direction angle transmission upper spur gear 222, wind direction angle reversal spur gear 221, and wind direction adjustment upper spur gear 22 are transmitted. That is, the direction of the wind direction adjusting upper spur gear 22 is transmitted to the wind direction adjusting lower spur gear 23, and the rotation torque generation execution angle of each curved blade 21 is corrected, so that each curved blade 21 has the maximum efficiency. Wind pressure.

For example, the wind direction rudder 223 is turned 90 degrees in the wind direction angle adjusting unit 225 after loosening the screw.
Tighten the screw again. Thereby, the direction of the wind direction adjusting upper spur gear 22 is changed by 90 degrees, and each curved blade 21 is a curved blade 21 to which wind pressure is not applied, a curved blade 21 to which wind pressure is applied on both sides of the center on average, The curved blades 21 cancel each other out of the wind pressure, and even if each of them rotates, no rotation torque is applied to the output rotation shaft 11.

The wind direction angle adjustment unit 225 can be adjusted manually, automatically, remotely, or the like. Also, the arrangement of the upper spur gear 222 for transmitting the wind direction angle, the upper spur gear 221 for reversing the wind direction angle, the upper spur gear 22 for adjusting the wind direction, the wind direction angle adjuster 225, the wind rudder 223, and the like are located below the holding frame 31. be able to. In the above case, in particular, the wind direction adjustment unit 225
Is manually adjusted, it can be adjusted at a low position.

The curved blade 21 rotates and revolves,
It can be used as an advertising medium or a display medium as well as a power generator or other energy converter.
In particular, since the rotation of the curved blade 21 and the rotation of the output rotary shaft 11 are slow, as an advertising medium and a display medium,
It is easy to see and can be seen from a distance even if it is large.

Although the embodiments of the present invention have been described in detail, the present invention is not limited to the above embodiments. And
The present invention is capable of various design changes without departing from the scope of the claims. Although the components, materials, and their mounting structures in the present embodiment are not described in detail, well-known or known components or means can be employed. In particular, for the curved blade, any of a plastic and a metal plate can be used, and integral molding, sheet metal processing, and other processing means can be adopted. In addition, off-the-shelf products can be used for the gears or the crank mechanism. The number, size, etc. of the curved blades can be arbitrarily increased or decreased by design.
