[0002] As a clean and renewable energy form, wind power generation has received widespread attention and application in recent years. Traditional wind turbines usually include components such as a casing, outer blades, a head and a generator body. The wind drives the outer blades to rotate, which in turn drives the head to rotate, and the generator body completes the power generation process. However, in actual applications, the power generation efficiency of wind turbines is often affected by many factors, such as changes in wind direction, blade length and angle, etc.

[0038] Working principle:

[0039] When in use, the wind can drive the multiple outer blades 6 to rotate, and then drive the head 8 to rotate. After the head 8 increases the speed through the gear box 9, the power generation process can be completed through the generator body 11. The outer rod 4 is rotatably sleeved on the inner rod 15. The setting of the inner rod 15 and the reinforcing rod 2 ensures the stability of the support rod 3.

[0040] When the wind direction changes, the angle of the wind deflector 13 is at an angle to the wind direction, and the wind deflector 13 starts to rotate. Since one end of the sliding rod 16 is spherical, the wind deflector 13 can drive the sliding rod 16 to rotate during the rotation, and the sliding rod 16 moves out from the inside of the third circular groove 21. After the sliding rod 16 no longer conflicts with the pushing rod 27, the pushing rod 27 and the sliding plate 24 move laterally under the tension of the tension spring 22. The repulsive force between the second magnet 26 and the first magnet 25 can also help the pushing rod 27. Horizontally move, push rod 27 moves out from the inside of the first circular groove 14, outer rod 4 and inner rod 15 are no longer connected, and drive motor 17 can be started at this time, the output shaft of drive motor 17 drives drive shaft 20 to rotate, drive shaft 20 drives outer rod 4 to rotate, outer rod 4 drives housing 5 to rotate, and then adjust the direction of outer fan blade 6 and head 8, when sliding rod 16 enters the inside of fourth circular groove 23 again, drive motor 17 is turned off at this time, so that the direction of head 8 is consistent with the direction of wind direction plate 13, so as to improve power generation efficiency;

[0041] When the length of multiple blades needs to be adjusted, the electric push rod 32 can be started to retract the piston rod of the electric push rod 32, the piston rod of the electric push rod 32 drives the sliding connecting rod 33 to move upward, the sliding connecting rod 33 drives the double-axis motor 36 to move upward, the double-axis motor 36 drives the upper rotating shaft 37 to push the upper pushing block 38 to move upward, the pushing block 38 drives the sliding sheet 28 to move upward, the sliding sheet 28 enters the interior of the first groove 30 and squeezes the spring 29, at this time the plug rod 44 moves out of the interior of the slot 45, the braking state of the first circular plate 31 is released, and the block 47 can be made to move upward. Aligned with the card slot 48, the card block 47 moves laterally under the elastic force of the compression spring 39 and is inserted into the card slot 48, and the dual-axis motor 36 is started. The output shaft of the dual-axis motor 36 drives the rotating shaft 37 to rotate, and then the first circular plate 31 can be driven to rotate, the first circular plate 31 drives the second gear ring 40 to rotate, the second gear ring 40 drives the second gear 43 to rotate, the second gear 43 drives the threaded rod 41 to rotate, and the threaded rod 41 drives the inner blade 7 to enter the inner part of the outer blade 6, and then the length of the blade can be adjusted. Shortening the length of the blade can reduce the force on the wind turbine generator and improve its stability and safety;

[0042] When the angles of multiple blades need to be adjusted, the electric push rod 32 can be started to extend the piston rod of the electric push rod 32. At this time, the rotating shaft 37 below pushes the push block 38 below to move downward, thereby releasing the braking state of the second circular plate 34, thereby driving the first gear ring 35 to rotate, the first gear ring 35 drives multiple first gears 42 to rotate, the first gear 42 drives the outer blades 6 to rotate, and then the angle of the outer blades 6 can be adjusted. The blade angle of the wind turbine can be adjusted according to the change in wind speed. When the wind speed is low, increasing the angle of attack of the blades can help the wind turbine better capture wind energy and rotate the generator; when the wind speed is high, reducing the angle of attack of the blades can reduce the speed and output power of the wind turbine to prevent it from overloading or damage;

[0043] Since the top and bottom of the first gear ring 35 are both arc-shaped and the side surface is flat, the first gear ring 35 can be driven to rotate when the rotating shaft 37 rotates, and the first gear ring 35 will automatically retract when the rotating shaft 37 moves downward.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
