[0032] The wind wheel device 4 includes a plurality of supports 6 fixedly connected to the outer ends of the frame 3, and a wind wheel shaft 7 is vertically arranged on the support 6. The upper and lower parts of the wind wheel shaft 7 are evenly and fixedly connected with a plurality of groups of wind wheel spokes 8 along the circumferential direction. The plurality of groups of wind wheel spokes 8 can be arranged only at the upper part or the lower part, and when arranged at the upper part or the lower part, more than one group can be arranged vertically, as long as the vertical space meets the requirements of the arrangement. Each group of wind wheel spokes 8 is arranged in the horizontal direction, and the number of each group of wind wheel spokes 8 is more than two, and in this embodiment, there are three.

[0033] The wind wheel spoke 8 comprises a spoke shaft 11 and a spoke hollow shaft 12 sleeved on the spoke shaft 11 , and bearings are arranged between the two ends of the spoke hollow shaft 12 and the spoke shaft 11 .

[0034] The inner end of the spoke shaft 11 of a single wind rotor spoke 8 is fixedly connected to the wind rotor shaft 7, and the outer end of the single wind rotor spoke 8 is rotatably connected to a vertically arranged blade 9, which is concave inward to one side in the vertical direction, and is concave in shape, thereby increasing the wind receiving surface and the stability of the wind receiving. The middle part of the blade 9 is connected to the spoke hollow shaft 12 of the wind rotor spoke 8 and rotates around the axis of the wind rotor spoke 8. The blade 9 is divided into two parts from the connection between the blade 9 and the wind rotor spoke 8, and the height of the upper part 9-1 is less than the height of the lower part 9-2.

[0035] An inner gear ring 13 with inner teeth 15 on the inner side is sleeved in the middle of the wind wheel shaft 7, and the concave inner gear ring 13 is filled with lubricating oil.

The generator 16 is located on the upper side of the support 6, and can also be located on the lower side of the support 6.

[0037] A bottom plate 17 is fixedly connected to the wind wheel shaft 7 below each wind wheel spoke rod 8, and the inner end of the bottom plate 17 is fixedly connected to the wind wheel shaft 7. Both ends of the bottom plate 17 are located on the inner side of the blade 9 on the corresponding side in the vertical direction, and the bottom plate 17 is parallel to the wind wheel spoke rod 8; a support plate 18 is fixedly connected to the wind wheel spoke rod 8, and a bottom plate bracket 19 is fixedly connected to the bottom plate 17. The lower end of the recoil assembly 5 is rotatably connected to the bottom plate bracket 19 through a horizontally arranged second pin shaft. The upper end of the recoil assembly 5 is rotatably connected to the support plate 18 through a horizontally arranged first pin shaft. The recoil assembly 5 is located outside the wind wheel shaft 7.

[0038] like Figure 3 As shown, the recoil assembly 5 (recoil hydraulic assembly) uses the hydraulic oil piston rod to automatically recoil by pulling up and down the support plate 18 on the hollow spoke shaft 12 on the wind wheel spoke 8 as the blades 9 swing.

[0039] The recoil assembly 5 includes a cylinder body 20, a piston rod 21 and a transverse partition 22. The cylinder body 20 is sealed and divided into a left chamber 23 and a right chamber 24. A vertical partition 25 is provided between the left chamber 23 and the right chamber 24. The bottoms of the left and right chambers 23 and 24 are connected. The piston rod 21 is vertically arranged in the left chamber 23 and is slidably connected to the cylinder body 20 at the left chamber 23. The upper end of the piston rod 21 extends out of the left chamber 23 and is connected to the first pin shaft. The lower end of the cylinder body 20 is hinged to the bottom plate bracket 19 through the second pin shaft. The lower end of the piston rod 21 is fixedly connected to a piston disc 26. A piston rubber ring 35 is provided around the outer edge of the piston disc 26 to seal and slide between the inner wall of the left chamber 23.

[0040] The diaphragm 22 is located below the piston plate 26 and is parallel to the piston plate 26. A bottom communication port 27 is provided between the bottoms of the left and right chambers 23 and 24. The bottom communication port 27 is located between the vertical diaphragm 25 and the bottom surface of the cylinder body 20 and is also located below the diaphragm 22. The top surface of the right chamber 24 is higher than the lower bottom surface of the diaphragm 22. A vent pipe 28 connecting the left and right chambers is provided between the outer side of the left chamber 23 and the top of the right chamber 24. An oil return hole 29 is provided on the transverse partition 22. The oil return hole 29 is located near the vertical partition 25. An oil inlet 30 is provided on the transverse partition 22. An upper cylinder 31 and a lower cylinder 32 are vertically installed at the oil inlet 30. The inner diameter of the upper cylinder 31 is larger than the inner diameter of the lower cylinder 32. The upper and lower ends of the upper cylinder 31 and the lower cylinder 32 are both open. The bottom surface of the upper cylinder 31 is a spherical bottom surface 33. A steel ball 34 is provided in the upper cylinder 31. The diameter of the steel ball 34 is smaller than the inner diameter of the upper cylinder 31 and larger than the inner diameter of the lower cylinder 32. When the steel ball 34 falls, the oil inlet 30 is blocked. Oil is provided below the piston disc 26. The right chamber 24 contains oil and air, and the space between the top surface of the right chamber 24 and the lower bottom surface of the transverse partition 22 is gas. When the piston plate 26 moves to the lowest position, the height of the oil level in the right chamber 23 should be less than or equal to the top surface height of the right chamber 23. The top surface height of the right chamber 23 needs to be specifically determined according to the specific volumes of the left chamber 23 and the right chamber 24 and the volume of oil that can be pushed by the piston plate 26. The top surface height of the right chamber 24 should ensure that when the diaphragm 22 moves to the lowest position, the oil reaches the top surface of the right chamber 24 at most, and the oil will not enter the top of the diaphragm 22 of the left chamber 23 through the vent pipe 28. There can also be oil and gas below the piston plate 26, but it should be ensured that the gas there will not enter the right chamber 24.

[0041] It should be noted that a bottom plate 17 can also be set above each wind wheel spoke 8, the recoil assembly 5 is set upward (to prevent oil from flowing out, the oil will flow out if it is installed upside down), the piston rod 21 is hinged to the support plate 18 through an inverted "L"-shaped connecting rod, and when the blades 9 rotate, the piston rod 21 will still be pulled downward, and when the blades 9 rotate in the opposite direction, the piston rod 21 will be pulled upward; the wind wheel spoke 8 can also be set only at the upper or lower part of the wind wheel shaft 7, and it does not necessarily have to be set at both the upper and lower parts; the inner gear ring 13 can be set not only at the middle position of the wind wheel shaft 7, but also at other positions of the wind wheel shaft 7. Such approximate changes all fall within the protection scope of the present invention.

[0042] Working process:

[0043] The wind blows the blades 9, and the blades 9 drive the wind wheel spokes 8 and the wind wheel shaft 7 to rotate, driving the generator 16 to generate electricity. At the same time, the bracket 3 drives the hollow sleeve 2 to rotate around the tower 1.

[0044] When the direction of the wind blowing on the blade 9 changes, the blade 9 drives the hollow shaft 12 on the spoke shaft 11 to rotate around the spoke shaft 11 according to the change of the wind receiving surface, and the rotation trajectory plane is parallel to the axis of the wind wheel shaft 7, that is, vertical. The hollow shaft 12 of the spoke is driven by the blade 9, and then drives the support plate 18 to pull the piston rod 21 upward or downward, pushing the piston disc 26 upward or downward. In the initial state, the blade 9 is in a vertical state, and the piston disc 26 is at the highest point of the left chamber 23. When the blade 9 tilts, the blade 9 rotates with the wind wheel spoke 8 and drives the support plate 18 to rotate with it, and the support plate 18 presses the piston disc 26 downward to move downward. When the blade 9 returns to the vertical state, the blade 9 rotates with the wind wheel spoke 8 in the opposite direction and drives the support plate 18 to rotate in the opposite direction, and the support plate 18 pulls the piston disc 26 upward to move upward.

[0045] When the piston plate 26 moves downward, the oil in the left chamber 23 will enter the bottom of the right chamber 24 through the bottom connecting port 27. The steel ball 34 moves downward with the flow of oil, closing the oil inlet 30. The oil can only enter the right chamber 24 below the diaphragm 22 through the oil return hole 29. The gas in the right chamber 24 will enter the left chamber 23 above the diaphragm 22 through the vent pipe 28. The oil height in the right chamber 24 gradually becomes greater than the oil height in the left chamber 23. Because the oil moves slowly, it plays a certain buffering role.

[0046] When the piston plate 26 is upward, the oil in the right chamber 24 will enter the bottom of the left chamber 23 through the bottom connecting port 27, and the steel ball 34 will move upward with the flow of oil, opening the oil inlet 30, and the oil will enter between the diaphragm 22 and the piston plate 26 through the oil inlet 30 and the oil return hole 29, and the gas above the diaphragm 22 in the left chamber 23 will enter the right chamber 24 through the vent pipe 28. The oil height of the right chamber 24 gradually decreases, but the oil movement speed is faster than when the piston plate 26 descends.

[0047] The present invention is a semi-direct drive constant frequency variable speed permanent magnet high efficiency generator set, that is, each set of wind wheels drives a generator respectively, the blades of this item can swing automatically, and the recoil assembly is used to automatically adjust the wind receiving area to form a small wind to produce a large force, a large wind to produce a small force, and a very large wind to produce normal power without risk. It increases the application time of effective wind speed, improves economic benefits and wind power quality, ensures the safety protection of the blades themselves, has a long service life, meets the requirements of dustproof, moisture-proof, and lightning protection conditions, can be large or small, and the wind wheel diameter is up to 5.4 meters.
