DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind power motor capable of extracting large power by using wind power.

[0002]

2. Description of the Related Art A wind power motor of this type is disclosed in Japanese Patent No. 2563048 filed by the present applicant. The schematic configuration of the wind motor is formed on a ground around a cylindrical guide, which is a cylindrical structure established on the ground, on a ground-shaped circular track centered on the cylindrical guide, and on a bogie traveling on this track, A large number of sets of mast frames higher than the cylindrical guides are vertically fixed at an angle of about 45 degrees in one direction with respect to the radiation from the center of the cylindrical guides. This is a construction of a wind rotating body.

In addition, a plurality of sails are pivotally mounted on each mast frame of the wind-rotating skeleton in vertical and axially multiple stages and openable and closable by wind force, and when the sail is closed with respect to the mast frame, the sails are about 45 degrees. Angle between the masts and the sail, between each mast and the sail, the maximum opening angle of the sail with respect to the mast frame is 6
A stopper that limits the angle to 5 to 85 degrees is provided.

[0004]

However, in a weather condition such as a typhoon, which is accompanied by a strong wind exceeding the wind condition normally assumed, a force greater than the limit strength acts on the sail stretched on the mast frame. In other words, the above-mentioned conventional wind power motor does not take measures against such a strong wind.

[0005] Also, in a state where the sail is being blown by strong winds,
The pivot angle of the sail suddenly changes with the rotation of the wind-rotating body, and each time the change, a part of the member supporting the sail repeatedly collides with the stopper that limits the opening angle of the sail. As a result, there arises a problem that an unexpected impact load occurs.

Accordingly, the present invention provides a wind turbine capable of maintaining safety in one direction even under weather conditions such as a typhoon accompanied by strong winds, ensuring safety, and suppressing abrupt operation of a mast frame on which a sail is stretched. It is intended to provide a prime mover.

[0007]

The hook support holes 36 are shown in FIGS. 9 (a) to 9 (c).
As shown in the figure, the narrow portion 21d of the release hook 21 is formed in the same square shape as the rod portion 21a of the release hook 21 and above the pull-out allowable groove 36a for allowing the release hook 21 to be pulled out. It is of a convex shape in cross-section formed with a vertically oblong pull-out preventing groove 36b that fits and prevents pull-out.

The cylinder chambers 29a and 29b and the partition wall 22
b, and when the space defined by the lower end of the release sliding rod 24 is not pressurized, the two release sliding rods 2
4 and 25 have moved downward, and FIG.
As shown in (a) to (c), the lower end of the lower release sliding rod 25 comes into contact with the obstruction plug 28, and the hook sliding holes 36 of the release sliding rods 24, 25 are pulled out. The blocking groove 36b is moved to a position facing the hook insertion hole 22a of the cylindrical body 22.

The compressed air causes the cylinder chambers 29a, 29
When the space defined by the partition wall 22b and the lower end of the release sliding rod 24 is pressurized, the release sliding rods 24 and 25 move upward, and the upper release sliding rod 24 moves. 10A abuts on the upper end of the stopper plug 27, and FIG.
As shown in FIGS.
Of the hook support holes 36 of the cylindrical body 22
Is moved to a position facing the hook insertion hole 22a.

Release hook 21 is inserted into hook insertion hole 22
a, the space defined by the cylinder chambers 29a and 29b and the partition wall 22b and the lower end of the release sliding rod 24 is pressurized, and
The release sliding rods 24, 25 are moved upward so that 6a faces the hook insertion hole 22a.

To prevent the release hook 21 from being pulled out, in other words, to keep the release hook 21 moored, the cylinder chambers 29a and 29b and the partition wall 22b
The pressurized state of the space defined by the lower end of the release sliding rod 24 is released, and the drive rod 26 and the release sliding rods 24, 25 are slid downward.

As a result, the narrow portion 21d of the release hook 21 is inserted into the pull-out preventing groove 36b of the hook support hole 36.
Each of the release hooks 21 is inserted from below.
Is moored by the release sliding rod 24 or the release sliding rod 25.

In order to allow the release hook 21 to be pulled out of the state where the release hook 21 is moored, the cylinder chambers 29a and 29b and the partition wall 22b and the release sliding rod 24 are again engaged. It is only necessary to make the space defined by the lower end of the pressurized state. As a result, the narrow portion 21d of the release hook 21 is pulled out of the pull-out preventing groove 36b of the hook support hole 36 into the pull-out allowable groove 36a, so that the release hooks 21 can be pulled out.

Therefore, only by applying an external force to the release hook 21 in the pull-out allowable state by the sails 3, 4 or the like receiving the wind, as shown in FIGS. The release hooks 21 can be pulled out, so that the sails 3 and 4 can be made to be in a windsock state that does not receive the wind.

By the way, as shown in FIG. 3, each mast frame B is held at a fixed angle α, preferably 45 degrees or closer to the radiation from the rotation center line O of the wind rotator A, as shown in FIG. It is rotatably supported between a first wind receiving position (a) and a second wind receiving position (b) further rotated by a required angle β, preferably 65 ° to 85 ° from this position. I have.

The first wind receiving position (a) and the second wind receiving position (b) come into contact with a part of the mast frame B moved to these positions to position the mast frame B. Stoppers (not shown) are provided.

At the first wind receiving position (a), the mast frame B
The wind received on one side surface 3c, 4c of the sails 3, 4 stretched over the wind can generate a force to rotate the wind-rotating skeleton A in one direction (counterclockwise in FIG. 3). That is, assuming that the wind direction is in the direction of the arrow W1, the sail 3 and the sail 4 each have a component force for rotating the wind-rotating frame A in the counterclockwise direction in the drawing.

Further, since a larger force is applied to the sail 4 than the force applied to the sail 3, a force for rotating the mast frame B clockwise about the support shaft 15 is generated. The frame B is maintained in a state of being positioned by being pressed by the positioning stopper at the first wind receiving position (a). In other words, the state in which the mast frame B is moved to the first wind receiving position (A) is maintained as long as the mast frame B receives the wind power on the one side surface 3c, 4c of the sail 3, 4.

In the second wind receiving position (b), the wind force received by the other side surfaces 3d and 4d of the sails 3 and 4 causes the wind rotating body A to move in the same manner as in the first wind receiving position (a). Direction can be generated. That is, assuming that the wind direction is the direction of the arrow W2, the sails 3 and 4 each have a component component of a force for rotating the wind-rotating frame A in the counterclockwise direction in the drawing.

Further, since a larger force is applied to the sail 4 than the force applied to the sail 3, a force for rotating the mast frame B in a counterclockwise direction about the support shaft 15 is generated. The state in which the mast frame B is positioned by being pressed by the positioning stopper at the second wind receiving position (b) is maintained. In other words, the state in which the mast frame B is moved to the second wind receiving position (b) is maintained as long as the mast frame B receives wind power on the other side surfaces 3d and 4d of the sails 3 and 4.

The both side members 18 and 19 of the mast frame B are wound around a part of a mast frame braking device D provided at an intermediate portion of the inside horizontal member 7 of the wind-rotating skeleton A, and Lumber 7
The two ends of a braking wire 38 stretched are connected via wire guides 37, 37 disposed at both ends of the mast frame B, whereby the rotation of the mast frame B is braked and decelerated.

FIG. 12 is a front sectional view of the mast frame braking device, and FIG. 13 is a sectional view taken along line III-III shown in FIG.

The mast frame braking device D includes a cylindrical case 42 and a rotating shaft 41 to which two centrifugal brake mechanisms 39 and 39 having the same configuration and a wire reel 40 are attached.
It is of a configuration housed inside.

The cylindrical case 42 has a main body 43 and a top plate 44 on which bearings 45, 45 of a rotating shaft 41 are formed. The partition walls 42a and 42b are formed in two upper and lower stages.

The wire reel 40 and the two centrifugal brake mechanisms 39, 39 are arranged with the wire reel 40 among them between the two partition walls 42a, 42b.
The two centrifugal brake mechanisms 39, 39 are connected to the upper partition wall 42.
a and on the lower side of the lower partition wall 42b.

The centrifugal brake mechanism 39 includes a wheel 46 fixed to the rotating shaft 41, six brakes 47, and the same number of compression coil springs 48, and the inner surface of the side wall of the main body 43, which faces the brake 47. And an annular brake band N attached to the portion. The wheel 46 has a braking element 47
Are arranged at intervals of 60 degrees around the rotation shaft 41.

The brake element 47 has an outer peripheral end surface formed to have the same curvature as the inner surface of the side wall of the cylindrical case 42, and has a sliding contact portion 47a having a brake pad 50 adhered to the outer peripheral end surface.
And a connecting rod 47 having this sliding contact portion 47a formed at the outer end.
b, a coil stopper 47c is formed at the inner end thereof.
A compression coil spring 48 is mounted around the connecting rod 47b.

The brake element accommodating portion 49 has an opening formed in the outer peripheral end surface of the wheel 46, and has a sliding contact portion 47 a of each brake element 47.
, Which are slidably inserted, coil stoppers 47c of all the brakes 47, and a housing 49b for housing the compression coil spring 48 between them and the inner wall surface. Consists of The wire reel 40 has a reel groove 40a formed on the outer peripheral end surface, and the intermediate portion of the braking wire 38 is wound around the reel groove 40a.

With the rotation of the mast frame B, the braking wire 38
Moves, the wheel 46 rotates together with the rotating shaft 41, and a centrifugal force acts on the brake element 47. When the moving speed of the brake wire 38 exceeds a predetermined value, the brake element 47 moves outward along the radiation while compressing the compression coil spring 48. By this movement, the brake pad 50 of the sliding portion 47a comes into sliding contact with the brake band N of the cylindrical case 42, and the braking wire 38 wound around the wire reel 40 is braked and decelerated.

When the brake wire 38 moves at a predetermined speed or less, the brake pad 50 of the sliding contact portion 47a is moved.
Does not slide on the brake band N of the cylindrical case 42 and therefore does not brake the brake wire 38. The upper limit of the moving speed at which the braking is performed can be arbitrarily set by appropriately combining the spring constant of the compression coil spring 48, the weight of the brake element 47, and the like.

Next, the operation of the entire apparatus will be described. <When the wind speed is equal to or lower than the assumed value> As shown in FIG. Move as follows.

A- positioned on the windward side as viewed from the cylindrical guide 1
The sails 3 and 4 of the mast frame B ... that have been moved to the range of B
While maintaining the first wind receiving position (a), that is, the angle of 45 degrees with respect to the radiation from the rotation center line O, wind is received on one of the side surfaces 3c and 4c, and the wind rotating body A
Causes a counterclockwise rotational force as shown in FIG.

The sails 3, 4 stretched on the mast frame B are:
When moving from the range of AB to the range of BC located on the leeward side, the wind force that has been received on one of the side surfaces 3c and 4c until then is received on the other side surfaces 3d and 4d.

At this time, due to the difference in the force generated between the two sails 3 and 4, a rotational moment is generated around the support shaft 15 in a direction opposite to that of the support shaft 15, and the mast frame B is moved to the first wind receiving position ( Rotate from b) to the second wind receiving position (b). When the rotation speed exceeds a predetermined value, the mast frame braking device D
As a result, the rotation is braked and rotated in a decelerated state.

The mast frame B moved to the range of B-C is
In the state moved to the second wind receiving position (B), a counterclockwise rotating force is generated in the wind rotating body A as in the first wind receiving position (A).

The mast frame B, which has been moved to the range of C-A at the intermediate position, is in a state of being rotated so that their directions are parallel to the wind direction. In other words, between the first wind receiving position (a) and the second wind receiving position (b), no rotation moment is generated around the support shaft 15 and the rotation is related to the rotation of the wind rotary body A. Not to be.

Therefore, the sails 3, 4... Stretched on the mast frame B moving in the range of AB and the range of BC generate a counterclockwise rotational moment, and The sails 3, 4,... Of the moving mast frame B have no rotational moment. Moreover, since such a relationship of generating the rotational moment is established in any direction of the wind,
The wind rotating body A always rotates counterclockwise regardless of the wind direction.

<When the wind speed exceeds the assumed wind speed> When the wind speed exceeds the assumed wind speed, the drive source 32 is operated automatically or manually by the wind speed sensor 34 to move the release sliding rods 24 and 25 upward, and Hook 2
1 is set in a state that allows pulling out. The range of allowable withdrawal state of the release hooks 21 is all the sails 3, 4 ...
, That is, the whole range may be set in the extraction allowable state, but as shown in FIG.
That is, the release hooks 21 that have been moved to the range AB and the range BC may be set in a pull-out allowable state.

The release hook 21 in the pull-out permitted state is pulled out from the hook insertion hole 22a of the tubular body 22 by the wind force applied to the sails 3 and 4 stretched thereby. As a result, the sails 3, 4 are blown off according to the wind direction with the inner edges 3a, 4a locked by the fixed hooks 20, as shown in FIG. In this way, no wind is applied to the sails 3, 4 and therefore the wind rotating body A can be prevented from rotating.

The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the invention. In the above, the drive source in which the release sliding rods 24 and 25 are driven by compressed air has been described. However, the drive source may have the following configuration.

The drive source 51 shown in FIG. 15 has a structure in which the release sliding rods 24, 25 are slid up and down by electromagnetic force, is screwed to the upper end of the release sliding rod 24, and Case 5 with coil 52 mounted on inner wall surface
3 and a cylindrical bulging portion 22f formed integrally with the upper end of the release sliding rod 24 and magnetically attracted by the coil 52. Reference numeral 54 denotes a closing plug which also serves as a stopper which is positioned in contact with the upper end of the release sliding rod 24, and reference numeral 54a denotes an air vent formed in the closing plug 54.

In the above description, the support shaft 15 is mounted on the mast frame B.
Although the sails 3 and 4 having different areas are stretched on both sides of the support shaft 15 of the mast frame B so as to generate a rotational force around The sails may be stretched so that the rotational force generated on the sails is generated at different distances from the support shaft 15.

[0066]

According to the present invention, each mast frame stretches large and small sails having different areas from each other on both sides of the support shaft of the mast frame. A first wind receiving position for generating a force for rotating the wind rotating skeleton in one direction, and a second wind for generating a force for rotating the wind rotating skeleton in the same direction by the wind received on the other side of the sails. Because it is rotatably supported between the wind receiving position, it can always maintain rotation in one direction even under weather conditions such as typhoons with strong winds, ensuring safety, and the mast frame is at a predetermined speed. Since the mast frame braking device is provided to reduce the rotation speed when rotating beyond the limit, abrupt operation of the mast frame can be suppressed to enhance safety.

Also, large and small sails having different areas are stretched on both sides of the support shaft of the mast frame, and rotation of the mast frame in one direction is maintained due to the difference in wind force received by the large and small sails. There is no need to provide a device or the like for holding the mast frame at the first and second wind receiving positions, and it is only necessary to stretch sails having different areas on both sides of the support shaft. It can be simpler.
