[0012] According to the above technical solution, the protective device includes a fixed box, a round rod, a contact plate, a rectangular plate and a tension spring. When the sliding frame moves and contacts the contact plate, the sliding frame moves to push the contact plate to move.

[0014] The present invention provides a wind power generation device that is self-adaptive to wind direction. It has the following beneficial effects:

[0015] (1) The self-adaptive wind direction wind turbine generator device has an annular pad that provides support for the casing and can also absorb the impact when the wind direction changes suddenly, reducing the shaking of the rotating shaft. Through the coordination of the fixed chuck and the annular pad, the radial and axial stability of the rotating shaft are improved, ensuring that the wind turbine can adapt to the change of wind direction efficiently and reliably. At the same time, the roller presses the inner wall of the circular tube, generating controllable friction resistance during the rotation of the rotating shaft. The controllable resistance provided by the roller prevents the wind turbine from frequently starting and stopping at low wind speeds or when the wind direction fluctuates frequently, reducing overall wear and extending the service life, thereby reducing the frequency and cost of maintenance.

[0016] (2) In the self-adaptive wind direction wind power generation device, the sliding frame drives the connecting plate to move, and the connecting plate drives the guide wheel to roll on the slide groove guide rail. By setting the guide wheel, the friction resistance between the sliding frame and the slide groove guide rail is effectively reduced, making the movement of the sliding frame more stable, and the guidance of the slide groove guide rail ensures that the movement of the sliding frame is always stable. At the same time, when the threaded sleeve moves to the terminal position of the thread groove, its movement is limited and stopped. Through the stroke limit of the thread groove, the maximum deflection angle of the wind turbine in two directions is effectively controlled to prevent it from excessive rotation, which causes the cable to be excessively twisted and broken.

[0017] (3) In the self-adaptive wind direction wind turbine generator, the rubber block generates moderate friction to ensure that the long rod can reliably drive the bearing ring to rotate and avoid slipping. The auxiliary support provided by the bearing ring makes the rotation of the long rod more stable, thereby ensuring that the threaded sleeve can move accurately along the thread groove, thereby ensuring that the adjustment process of the wind turbine is stable and reliable.

[0018] (4) In the self-adaptive wind direction wind power generation device, the rebound force exerted by the tension spring on the rectangular plate provides continuous resistance for the sliding frame. When the sliding frame approaches the end of the thread groove, the moving speed is effectively buffered to prevent it from colliding with the long rod, ensuring that the thread groove will not be damaged by the impact, and maintaining the integrity of the long rod. At the same time, the rectangular plate increases the moving resistance of the sliding frame and improves the deceleration effect. The design of the triangular block can improve the effect of slowing down the moving speed of the sliding frame, and can also reduce the resistance to its own reset through its inclined surface, which helps to improve the applicability of the triangular block.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1 - Figure 6 One embodiment of the present invention is: an adaptive wind direction wind power generation device, including a support rod 1 and a wind turbine 2, the surface of the wind turbine 2 is provided with a wind direction tail, the wind direction tail is used to automatically adjust the direction of the wind turbine 2, and also includes: a circular tube 3, the circular tube 3 is fixedly mounted on the top of the support rod 1, the circular tube 3 is composed of two semicircular tube bodies; a fixed chuck 4, the fixed chuck 4 is fixedly mounted on the inner wall of the circular tube 3; a rotating shaft 5, the rotating shaft 5 is rotatably mounted on the inner wall of the fixed chuck 4, and the rotating shaft 5 is fixedly connected to the wind turbine 2; a casing 6, the casing 6 is fixedly mounted on the circumferential surface of the rotating shaft 5, and an annular groove is opened on the surface of the casing 6; an annular pad 7, the annular pad 7 is rotatably mounted in the annular groove, and the annular pad 7 is in contact with the top of the circular tube 3. Through the cooperation of the fixed chuck 4 and the annular pad 7, the radial and axial stability of the rotating shaft 5 are improved, ensuring that the wind turbine 2 can efficiently and reliably adapt to changes in wind direction.

[0030] A fixing tube 8 is fixedly passed through the circumferential surface of the casing 6, and a carrying rod 9 is slidably passed through the side of the fixing tube 8 away from the casing 6. A spring 10 is arranged between the carrying rod 9 and the fixing tube 8. One end of the spring 10 is fixedly connected to the inner wall of the fixing tube 8, and the other end of the spring 10 is fixedly connected to the surface of the carrying rod 9. A roller 11 is rotated and passed through the surface of the carrying rod 9. The roller 11 contacts the inner wall of the circular tube 3, and a controllable resistance is provided by the roller 11 to prevent the wind turbine 2 from frequently starting and stopping when the wind speed is low or the wind direction fluctuates frequently, thereby reducing overall wear and extending the service life.

[0031] A long rod 12 is fixedly installed at the bottom of the rotating shaft 5, and a wire drawing groove is provided on the surface of the support rod 1. The wire drawing groove is used to guide and fix the wire. By opening the wire drawing groove, the fixing wire can be easily passed through the wire drawing groove, thereby enhancing the stability of the support rod 1 itself.

[0032] When the wind direction is stable, the forces on both sides of the wind direction tail wing are balanced, and the wind turbine 2 maintains its current direction. When the wind direction changes, the forces on both sides of the wind direction tail wing are uneven, generating a rotational torque, which drives the wind turbine 2 to drive the rotating shaft 5 to rotate until the wind turbine 2 is realigned to the new wind direction. In this process, the circular tube 3 provides radial support for the rotating shaft 5 through the fixed chuck 4, and the rotating shaft 5 drives the sleeve 6 and the long rod 12 to rotate synchronously. When the sleeve 6 rotates, the annular pad 7 on the sleeve 6 fits tightly with the top of the circular tube 3, and the friction resistance between the annular pad 7 and the circular tube 3 keeps it stationary. The annular pad 7 in the stationary state not only provides supporting force for the sleeve 6, but also absorbs the impact when the wind direction suddenly changes, reduces the shaking of the rotating shaft 5, and ensures that the wind turbine 2 remains stable during the steering process. Through the cooperation of the fixed chuck 4 and the annular pad 7, the radial and axial stability of the rotating shaft 5 are improved, ensuring that the wind turbine 2 2 can efficiently and reliably adapt to changes in wind direction. When the housing 6 rotates, it drives the fixed tube 8 to rotate synchronously, and the fixed tube 8 drives the carrying rod 9 to rotate synchronously. The carrying rod 9 further drives the roller 11 to roll along the inner wall of the circular tube 3. At this time, the spring 10 in the stretched state applies elastic tension to the carrying rod 9, forcing the roller 11 to press against the inner wall of the circular tube 3, thereby generating controllable friction resistance during the rotation of the rotating shaft 5. When the wind speed change does not reach the set threshold, the resistance is sufficient to offset the driving effect of the wind force, so that the rotating shaft 5 remains stationary, avoiding frequent rotation of the wind turbine 2. When the wind speed reaches or exceeds the threshold, the driving torque of the wind force overcomes the resistance, so that the rotating shaft 5 rotates smoothly, driving the wind turbine 2 to realign with the wind direction. The roller 11 provides controllable resistance, preventing the wind turbine 2 from frequently starting and stopping when the wind speed is low or the wind direction fluctuates frequently, reducing overall wear and extending the service life, thereby reducing the frequency and cost of maintenance.

[0033] See also Figure 1 - Figure 8On the basis of the above embodiment, in another embodiment of the present invention, a limiting device for improving the rotation stability of the rotating shaft 5 is provided on the circular tube 3, and a protective device for improving the movement safety of the sliding frame 25 is provided on the slide guide rail 24; the limiting device includes a hollow tube 21, a bearing ring 22 and a rubber block 23, the hollow tube 21 is fixedly mounted on the inner wall of the circular tube 3, and circular holes are opened on the upper and lower surfaces of the hollow tube 21, and the bearing ring 22 is rotatably mounted in the circular hole. A rubber block 23 is fixedly mounted on the surface of the bearing ring 22, and the bearing ring 22 is in contact with the circumferential surface of the long rod 12, and the rubber block 23 is in contact with the circumferential surface of the long rod 12. The auxiliary support provided by the bearing ring 22 makes the rotation of the long rod 12 more stable, thereby ensuring that the adjustment process of the wind turbine 2 is stable and reliable.

[0034] A slide guide rail 24 is fixedly installed on the inner wall of the hollow tube 21, and a sliding frame 25 is slidably installed on the inner wall of the slide guide rail 24. A threaded sleeve 26 is rotatably installed on the inner wall of the sliding frame 25. A threaded groove is provided on the circumferential surface of the long rod 12, and the threaded sleeve 26 is threadedly connected to the threaded groove of the long rod 12. A movable groove is provided on the surface of the slide guide rail 24. The stroke limit of the threaded groove effectively controls the maximum deflection angle of the wind turbine 2 in two directions to prevent it from excessive rotation, which causes the cable to be excessively twisted and broken.

[0035] A connecting plate 27 is fixedly installed on the surface of the sliding frame 25, and a guide wheel 28 is rotatably installed on the inner wall of the connecting plate 27. The guide wheel 28 contacts the surface of the slide groove guide rail 24. By providing the guide wheel 28, the friction resistance between the sliding frame 25 and the slide groove guide rail 24 is effectively reduced, making the movement of the sliding frame 25 smoother.

[0036] The protective device includes a fixed box 31, a round rod 32, a contact plate 33, a rectangular plate 34 and a tension spring 35. The fixed box 31 is fixedly mounted on the surface of the slide guide rail 24, the round rod 32 slides through the bottom of the fixed box 31, the contact plate 33 is fixedly mounted on the bottom of the round rod 32, the rectangular plate 34 is fixedly mounted on the top of the round rod 32, and the tension spring 35 is arranged between the rectangular plate 34 and the fixed box 31. One end of the tension spring 35 is fixedly connected to the inner wall of the fixed box 31, and the other end of the tension spring 35 is fixedly connected to the surface of the rectangular plate 34. The contact plate 33 contacts the movable groove. When the sliding frame 25 approaches the terminal end of the thread groove, the moving speed is effectively buffered to prevent it from colliding with the long rod 12, ensuring that the thread groove will not be damaged due to impact, thereby maintaining the integrity of the long rod 12.

[0037] A triangular block 36 is fixedly installed on the surface of the rectangular plate 34, and a number of rectangular pieces 37 are fixedly installed on the inner wall of the fixed box 31. The rectangular pieces 37 are elastic. Through the design of the triangular block 36, the effect of slowing down the movement speed of the sliding frame 25 can be improved, and the resistance to its own reset can be reduced through its inclined surface, which helps to improve the applicability of the triangular block 36.

[0038] When the rod 12 rotates clockwise, its threaded groove drives the threaded sleeve 26 to move downward, and vice versa, when the rod 12 rotates counterclockwise, the threaded sleeve 26 moves upward; in this process, the threaded sleeve 26 drives the sliding frame 25 to slide along the sliding groove guide rail 24, and the sliding frame 25 drives the connecting plate 27 to move synchronously, and the connecting plate 27 further drives the guide wheel 28 to roll on the sliding groove guide rail 24. By setting the guide wheel 28, the friction resistance between the sliding frame 25 and the sliding groove guide rail 24 is effectively reduced, so that the movement of the sliding frame 25 is more stable, and the guidance of the sliding groove guide rail 24 ensures that the movement of the sliding frame 25 is always stable. When the threaded sleeve 26 moves along the rod 12 to the terminal position of the threaded groove, its movement is limited and stopped. At this time, the rotation of the rod 12 is forced to stop, thereby limiting the continued rotation of the rotating shaft 5 and the wind turbine 2. When the wind direction changes in the opposite direction, the wind turbine 2 rotates in the opposite direction under the action of the wind direction tail. The rotating shaft 5 is synchronously reversed, thereby driving the long rod 12 to rotate in the opposite direction. At this time, the threaded sleeve 26 begins to move along the thread groove toward the terminal end in the opposite direction. The stroke limit of the thread groove effectively controls the maximum deflection angle of the wind turbine 2 in both directions to prevent it from over-rotating, which causes the cable to be excessively twisted and broken. When the bearing ring 22 rotates, it drives the bearing ring 22 to rotate synchronously, and the bearing ring 22 drives the rubber block 23 to rotate synchronously. At this time, the rubber block 23, which is tightly fitted with the long rod 12, generates appropriate friction between the long rod 12 and the bearing ring 22, ensuring that the long rod 12 can reliably drive the bearing ring 22 to rotate and avoid slipping. At the same time, the bearing ring 22 provides additional radial support for the long rod 12, enhancing its rotational stability. The auxiliary support provided by the bearing ring 22 makes the rotation of the long rod 12 more stable, thereby ensuring that the threaded sleeve 26 can move accurately along the thread groove, thereby ensuring that the adjustment process of the wind turbine 2 is stable and reliable.

[0039] When the sliding frame 25 moves to contact with the contact plate 33, as the sliding frame 25 continues to move, it pushes the contact plate 33 to move toward the fixed box 31, and the contact plate 33 drives the round rod 32 and the rectangular plate 34 to move synchronously. In this process, the rectangular plate 34 gradually stretches the tension spring 35, causing it to produce elastic deformation. As the deformation of the tension spring 35 increases, the rebound force exerted on the rectangular plate 34 also increases, thereby providing continuous resistance for the sliding frame 25 to move toward the terminal end of the thread groove. When the sliding frame 25 approaches the terminal end of the thread groove, the moving speed is effectively buffered to prevent it from colliding with the long rod 12, ensuring that the thread groove will not be damaged due to impact, and maintaining the integrity of the long rod 12. When the rectangular plate 34 moves in the direction away from the contact plate 33, it drives the triangular block 36 to move synchronously. During the process, the triangular block 36 contacts the rectangular piece 37 and applies pressure, forcing the rectangular piece 37 to bend elastically. The bent rectangular piece 37 generates reverse resistance to the triangular block 36, thereby increasing the movement resistance of the sliding frame 25 and improving the deceleration effect. When the triangular block 36 is completely separated from the rectangular plate 34, the rectangular plate 34 recovers under the action of the elastic restoring force; when the rectangular plate 34 drives the triangular block 36 to reset, the inclined surface of the triangular block 36 will squeeze the rectangular piece 37, causing it to bend briefly, but the bent rectangular piece 37 quickly separates from the triangular block 36, reducing the reset resistance and ensuring that it can be smoothly reset to the initial position. Through the design of the triangular block 36, the effect of slowing down the movement speed of the sliding frame 25 can be improved, and the resistance to its own reset can be reduced through its inclined surface, which helps to improve the applicability of the triangular block 36.
