[0026] In the description of the embodiments of the present application, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components.

[0027] See also Figure 1-Figure 3 As shown, an embodiment of the present application provides a wind power generation device, which mainly includes a mounting frame 1, a generator 2, and a wind-receiving rotating assembly 3. The generator 2 is fixedly mounted at the bottom of the mounting frame 1. The wind-receiving rotating assembly 3 is integrally mounted inside the mounting frame 1. Specifically, the wind-receiving rotating assembly 3 includes a wind-receiving blade 31, a rotating shaft 311, and a regulating assembly 32. The wind-receiving blade 31 has an axially telescopic structure and is axially slidably mounted on the rotating shaft 311. The lower end of the rotating shaft 311 is transmission-connected to the generator 2. The regulating assembly 32 is mounted on the mounting frame 1 and connected to the wind-receiving blade 31 to drive the wind-receiving blade 31 to axially telescope. The above-mentioned wind power generation device is designed with a wind-receiving blade 31 having a telescopic structure. In conjunction with the regulating assembly 32, the wind-receiving blade 31 is driven to telescope, thereby adjusting the wind-receiving area. Specifically, the regulating assembly 32 drives the wind-receiving blade 31 downward along the rotating shaft 311. The contraction of the wind-receiving blade 31 during its downward movement can reduce the wind-receiving area of ​​the wind-receiving blade, thereby reducing damage to the device caused by strong winds, thereby ensuring the long-term operation of the power generation device.

[0028] In some embodiments, in order to simplify the structure, the mounting frame 1 can be composed of two horizontal bars and two vertical bars. The two horizontal bars are arranged horizontally and parallel, and the two vertical bars are fixedly connected to the two ends of the two horizontal bars to form a rectangular frame structure. The overall structure is simple and the cost is low.

[0029] It can be understood that the generator 2 is installed on the horizontal bar located below (located in the middle position), and the control component 32 is installed on the horizontal bar located above. The upper and lower ends of the rotating shaft 311 can be connected to the two horizontal bars respectively through rotating connectors such as bearings, so that the wind-receiving blades 31 can rotate when receiving wind to drive the generator 2 to generate electricity.

[0030] In some embodiments, in order to provide an axially sliding mounting structure with a simplified structure, the wind-receiving blade 31 can be axially slidably mounted on the rotating shaft 311. Our wind-receiving rotating assembly 3 also includes two sliding seats 312, which are slidably connected to the rotating shaft 311. The two sliding seats 312 are initially located at the upper and lower ends of the rotating shaft 311, and the wind-receiving blade 31 is connected to the rotating shaft 311 via the two sliding seats 312; the sliding seats 312 are able to slide freely along the axial direction of the rotating shaft 311, but are circumferentially fixed and rotate synchronously with the rotating shaft 311; the regulating assembly 32 is connected to the sliding seat 312 at the upper end, and is used to drive the sliding seat 312 to move axially.

[0031] In some embodiments, the sliding seat 312 is annular and is sleeved on the rotating shaft 311 and connected by a key. The sliding structure formed by the flat key is relatively simple, easy to process, and low in cost.

[0032] In some embodiments, the wind-receiving blade 31 includes a first blade 314 and a second blade 315, and the first blade 314 and the second blade 315 are partially overlapped. Figure 2 As shown. The first blade 314 is fixedly connected to the sliding seat 312 located above, and the second blade 315 is fixedly connected to the sliding seat 312 located below. By providing two independent blades (the first blade 314 and the second blade 315), the overlapping structure between the first blade 314 and the second blade 315 is utilized to realize the telescopic structure of the wind-receiving blade 31, thereby adjusting the wind-receiving surface of the wind-receiving blade 31. Specifically, the first blade 314 (corresponding to the sliding seat 312) is driven downward by the regulating component 32, so that the first blade 314 and the second blade 315 partially overlap, thereby reducing the wind-receiving area of ​​the wind-receiving blade 31.

[0033] In a further embodiment, the first blade 314 has a reinforcing rib 313 on its inner side, which is fixedly connected to the corresponding sliding seat 312. The second blade 315 also has a reinforcing rib 313 on its inner side, which is fixedly connected to the corresponding sliding seat 312. The provision of the reinforcing rib 313 can strengthen the blades to further prevent damage from strong winds, while also strengthening the connection structure with the sliding seat 312.

[0034] In a further embodiment, the first blade 314 has a plurality of positioning seats 316 on its inner side, with axial through-holes extending therefrom. The second blade 315 has a plurality of directional guide rods 317 on its inner side, which engage with the positioning seats 316 through the through-holes. During the overlapping engagement of the first and second blades 314, 315, the directional guide rods 317 remain engaged with the through-holes, ensuring that the first and second blades 314, 315 remain integral and enhance overall stability.

[0035] In some embodiments, the control assembly 32 can be mainly composed of an electric push rod 321, a driving rod 322 and a connecting rod 323, and the overall structure is simple and reliable. Figure 2 One end of the electric push rod 321 is fixed to the mounting frame 1, and the other end is fixedly connected to the connecting rod 323; one end of the driving rod 322 is connected to the sliding seat 312, and the other end is fixedly connected to the connecting rod 323. The electric push rod 321 drives the driving rod 322 to move up and down, and the up and down movement of the driving rod 322 can drive the first blade 314 to move up and down.

[0036] To sum up, when the present invention is in use, under normal circumstances, the first blade 314 cooperates with the second blade 315, and the wind blows the windward surface to drive the rotating tube 311 to rotate through the sliding seat 312, and the rotating tube 311 drives the generator 2 to generate electricity; when the external wind force increases, the electric push rod 321 drives the driving rod 322 to move downward, and when the driving rod 322 moves up and down, it drives the upper end sliding seat 312 to move synchronously, so that the first blade 314 moves downward, and the second blade 315 is stored on the inner surface of the first blade 314, thereby reducing the windward area.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them.
