[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0030] like Figures 1 to 4 As shown, the present embodiment relates to a wind motor. Specifically, the wind motor includes a frame 1 with a vertical main shaft 2 (the rotation angle of the vertical main shaft 2 is 0 to 360 degrees), the vertical shaft 2 is fixed to the frame 1 by two bearings 21 and can rotate, the vertical main shaft 2 is provided with two pairs of valve-type fan blades 3, and each pair of valve-type fan blades 3 are centrally symmetrically arranged, and the two pairs of valve-type fan blades 3 form a cross-shaped structure, that is, adjacent valve-type fan blades 3 are perpendicular to each other. Here, the structure formed by the vertical main shaft 2 and the two pairs of valve-type fan blades 3 is a valve-type fan blade structure; the valve-type fan blade 3 includes a vertical valve shaft 32 and a wind blade 34 fixedly connected to the vertical valve shaft 32, and two upper and lower transverse support rods 31 are connected between the vertical main shaft 2 and the vertical valve shaft 32 to form an outer door frame of the wind blade 34, and the vertical valve shaft 32 is rotationally connected to the two transverse support rods 31.

[0031] Among them, a blocking rod 33 is arranged between the two transverse support rods 31, and the two ends of the blocking rod 33 are respectively connected to the two transverse support rods to support the two transverse support rods 31; and the distance between the blocking rod 33 and the vertical valve shaft 32 is smaller than the width of the wind blade 34 to limit the wind blade 34.

[0032] In the embodiment of the present invention, a limit lock 321 is provided on the vertical valve shaft 32, and a cam 3211 is provided on the limit lock 321. A boss 311 matching the cam 3211 is provided on the lateral support rod 31 to clamp the cam 3211 when the vertical valve shaft 32 rotates, so that the maximum rotation angle of the vertical valve shaft 32 is 180°, and the limit lock 321 is used together with the gear lever 33 to limit the rotation angle of the wind blade 34 fixed on the vertical valve shaft 32 to 0-180° (the maximum rotation angle is as shown in FIG. Figure 4 Furthermore, a screw hole is provided on the limit lock 321 to fix the limit lock 321 on the vertical valve shaft 32 by means of a screw 3212. By loosening the screw 3212, the position of the cam 3211 can be adjusted by rotating the limit lock 32, thereby changing the position of the cam 3211 relative to the boss 311 to adjust the rotation angle of the vertical valve shaft 32.

[0033] In an embodiment of the present invention, two methods can be used to prevent the fan blades from directly colliding with the baffle rod 33 when reversing and resetting. One method is to configure a buffer pad on the side of the baffle rod 33 facing the fan blade 34 to buffer the collision between the fan blade 34 and the baffle rod 33, thereby preventing the fan blade 34 from directly colliding with the baffle plate and reducing the sound of the collision; the other method is to provide an electromagnet on the baffle rod 33, and another electromagnet is provided on the fan blade 34 corresponding to the electromagnet, and the relative surface magnetic poles of the two electromagnets are the same, that is, the principle of repulsion of like magnetic poles is used to prevent the fan blade 34 from colliding with the baffle plate, thereby completely eliminating the noise of the collision and the damage to the fan blade 34 and the baffle plate 33 caused by the collision.

[0034] In an embodiment of the present invention, Figure 2 As shown, the frame 1 is a rectangular parallelepiped frame 1 including a top frame, a bottom support and columns arranged between the top frame and the bottom support, and a first fixed plate 11 and a second fixed plate 12 perpendicular to each other are arranged in the top frame, and a third fixed plate 13 and a fourth fixed plate 14 perpendicular to each other are arranged in the bottom support for setting a vertical main axis 2, and the centers of the first fixed plate 11 and the second fixed plate 12 coincide with the center of the top frame, and the centers of the second fixed plate 13 and the second fixed plate 14 coincide with the center of the bottom support, and the vertical main axis 2 is located on the longitudinal center axis of the rectangular parallelepiped frame 1 to make the vertical main axis 2 more stable.

[0035] In an embodiment of the present invention, Figure 3 As shown, a first electromagnet 10 is fixedly arranged on the above-mentioned base, and the first electromagnet 10 is arranged around the vertical main shaft 2 and has no contact with the vertical main shaft 2 to prevent the first electromagnet 10 from affecting the rotation of the vertical main shaft 2; a second electromagnet 20 is fixedly sleeved on the vertical main shaft 2 corresponding to the first electromagnet 10, and the second electromagnet 20 is located directly above the first electromagnet 10 and has a certain distance from the first electromagnet 10, and the relative surface magnetic poles of the first electromagnet 10 and the second electromagnet 20 are the same, so as to utilize the principle of magnetic suspension to suspend the weight of the vertical main shaft 2 and the valve-type fan blade 3 in the middle to further reduce the rotational resistance of the vertical main shaft 2.

[0036] In an embodiment of the present invention, Figure 5 As shown, the wind blade 34 may be a whole wind blade or may include a plurality of sub-blades; if the wind blade 34 includes a plurality of sub-blades 341, adjacent sub-blades 341 are connected together by springs 342, so that when the wind blade 34 is impacted by strong wind (for example, when the wind force exceeds the design range), the spring 342 will be stretched and the wind energy will be unloaded from the gap of the spring 342, so as to improve the stability and service life of the wind motor.

[0037] Preferably, the wind blade 34 includes a blade frame and a blade disposed in the blade frame, and the blade may be made of canvas or other materials.

[0038] The following is combined with Figure 6 and attached Figure 7 The principle of the wind motor of the present invention is described in detail:

[0039] The four valve-type fan blades of the air motor are respectively valve-type fan blade A, valve-type fan blade B, valve-type fan blade C and valve-type fan blade D.

[0040] Specifically, when the wind is working, the flap-type fan blade structure rotates to Figure 6 In the position shown, valve blade A and valve blade C are both perpendicular to the wind direction, and valve blade B and valve blade D are both parallel to the wind direction. At this time, the wind blades of valve blade A are in a fully closed state, the wind blades of valve blade C are in a fully open state, and the wind blades of valve blade B and valve blade D are also in a fully closed state because they are parallel to the wind direction. At this time, the wind pushes the wind blades of valve blade A to rotate counterclockwise, which will inevitably drive the valve blade structure to rotate counterclockwise, and at this time the wind energy difference on both sides of the valve blade structure is the largest, so that greater wind energy can be obtained.

[0041] When the valve-type fan blade structure continues to rotate counterclockwise to Figure 7When in the position shown, each door-type fan blade is at an angle of 45° to the wind direction. At this time, the fan blades of the valve-type fan blade B and the fan blades of the valve-type fan blade C are open and parallel to the wind direction, and the fan blades of the valve-type fan blade A and the fan blades of the valve-type fan blade D are completely closed. At this time, the wind pushes the fan blades of the valve-type fan blade A and the fan blades of the valve-type fan blade D to rotate counterclockwise, which will inevitably drive the valve-type fan blade structure to continue to rotate counterclockwise. Since the rotation angle of the vertical main axis is 0 to 360°, the other wind directions are also the same. In order to reduce redundancy, they will not be listed here one by one. It can be seen from this that the valve-type fan blade structure of the present invention is not affected by the wind direction, and the 360° wind direction has only one rotation direction, and there is no forward or reverse rotation, so it can improve the utilization rate of wind energy.

[0042] In addition, if Figure 8 As shown, the present invention also discloses a pneumatic motor combination structure. Specifically, the pneumatic motor combination structure includes two pneumatic motor units arranged in coordination with each other, and each pneumatic motor unit includes two pneumatic motors stacked up and down in sequence; wherein, the two pneumatic motors in each pneumatic motor unit are stacked up and down, and the vertical main shafts of adjacent pneumatic motors are connected by a coupling 4; a sprocket 5 is provided on the vertical main shaft of each pneumatic motor unit, and the sprockets 5 of adjacent pneumatic motors are connected together by a chain 6.

[0043] Since the outer frame of the above-mentioned wind motor is a rectangular frame structure, as long as these rectangular frame structures are placed and stacked in an array (how to place and how to arrange them can be determined according to the specific situation, for example, they can be stacked in a building style), and these wind motors are connected to the power generation equipment through a speed changer, a large wind motor combination structure can be formed. Obviously, such a large wind motor combination structure has a stable structure, is not affected by bad weather, and has a high safety factor.
