[0027] Embodiment 1

[0028] The utility model provides a novel wind energy conversion device, including a power generation device 1, the power generation device 1 is connected to a guide rod 3 through a transmission structure 2, the guide rod 2 rotates, and the input shaft of the power generation device 1 is driven to rotate through the transmission structure 2 to generate electricity, which is a prior art and will not be described in detail here; the utility model wind energy conversion device also includes:

[0029] The umbrella leaf 4 is rotatably connected to the side of the guide rod 3. When the wind blows, the wind acts on the surface of the umbrella leaf 4, and drives the guide rod 3 to rotate around its own axis through the umbrella leaf 4.

[0030] The collar 5 is slidably sleeved on the surface of the guide rod 3, and is connected to the umbrella leaf 4 by a connecting rod 6. The two ends of the connecting rod 6 are rotatably connected to the umbrella leaf 4 and the collar 5 respectively. When the collar 5 slides toward the direction of the power generation device 1, the umbrella leaf 4 is pushed to close toward the direction of the power generation device 1 through the connecting rod 6. In windy weather, when the wind force is too strong, the umbrella leaf 4 will be pushed to close in the opposite direction, pushing the collar 5 to move in the opposite direction, so that the umbrella leaf 4 is closed on the side away from the power generation device 1, reducing the contact area with the wind, thereby reducing the force;

[0031] A return spring 7, one end of which is fixedly connected to the guide rod 3, and the other end of which is fixedly connected to a side of the collar 5 close to the umbrella leaf 4;

[0032] The limiting mechanism 8 is used to limit the collar 5 on the guide rod 3, and includes a limiting spring 81 and a pin 82. The pin 82 is slidably arranged inside the side of the guide rod 3, and the limiting spring 81 is connected between the side of the guide rod 3 and the rear end of the pin 82. The inner surface of the collar 5 is provided with a limiting groove 51 corresponding to the head of the pin 82. Under normal circumstances, since the head of the pin 82 is inserted into the limiting groove 51 on the inner surface of the collar 5, under the action of friction, the collar 5 can be limited from moving on the guide rod 3. When the wind force is strong, the thrust of the umbrella leaf 4 acting on the collar 5 through the connecting rod 6 will also increase. When the wind force reaches a certain level, the friction between the pin 82 and the collar 51 will be insufficient to limit the collar 51, so that the pin 82 automatically slides backward to compress the limiting spring 81, and its head is separated from the limiting groove 51.

[0033] The above structure is described in detail below. When there is no wind, the umbrella leaf 4 is closed on the side close to the power generation device 1 under the action of the return spring 7. When the wind blows, the umbrella leaf 4 is pushed to open. The umbrella leaf 4 opens and rotates under the action of the wind to generate electricity. When the wind is strong, the collar 5 is pushed to break away from the limit of the limit mechanism 8, so that the umbrella leaf 4 is closed on the side away from the power generation device 1, reducing the contact area with the wind, thereby reducing the force and preventing it from being scratched.

[0034] It is worth mentioning that the wind energy conversion device of the utility model also includes a damping structure 9, which is connected between the tail end of the guide rod 3 and the side of the ring 51. In this embodiment, the damping structure 9 includes an air bag 91 mounted on the end of the guide rod 3, and an air hole 92 is provided on the side of the air bag 91. One end of the air bag 91 is fixed to the end of the guide rod 3, and the other end of the air bag 91 is fixed to the side of the ring 5. When the wind is too strong, the umbrella leaf 4 will close in the direction of the damping structure 9, pushing the ring 5 to slide and compress the air bag 91. When the air bag 91 is compressed, it exhausts air outward through the air hole 92 to perform work, thereby playing a buffering role.

[0035] Specifically, a guide groove 31 is embedded in the side surface of the guide rod 3 , and a guide block 52 is integrally formed on the inner wall of the collar 5 . The guide block 52 is slidably connected to the guide groove 31 .

[0036] A limit block 32 is fixed to the end of the guide rod 3 .

[0037] A mounting seat 33 is fixed on the side of the guide rod 3 , a shaft 34 is fixed to the mounting seat 33 , and the umbrella leaf 4 is rotatably connected to the shaft 34 .

[0038] Embodiment 2

[0039] Different from the first embodiment, the damping structure 9 includes a buffer spring 91a, one end of the buffer spring 91a is fixed to the end of the guide rod 3, and the other end of the buffer spring 91a is fixed to the side of the ring 5. When the wind force is too strong, the ring 5 is pushed to slide toward the end of the guide rod 3, that is, the direction of the limit block 32. During sliding, the buffer spring 91a is compressed for buffering. Of course, after the strong wind stops, the elastic force of the buffer spring 91a will also push the ring 51 to move in the opposite direction until it is limited by the limit mechanism 8. At this time, through the action of the connecting rod 6, the umbrella leaf 4 will also be reopened and restored to normal operation.

[0040] The embodiment and drawings of the present utility model are only for illustrating the design concept of the present utility model, and the protection scope of the present utility model should not be limited to this embodiment.

[0041] It can be seen from the above description that the design purpose of the utility model can be effectively implemented. The embodiment part shows the purpose of the utility model and the implementation function and structural theme, and includes other equivalent replacements.

[0042] Therefore, the rights of the present utility model include other equivalent implementations, and the specific scope of rights is referred to the claims.
