Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present invention are only for the convenience of clear narration, rather than used to limit the scope of implementation of the present invention. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the present invention.

[0024] Refer to Figures 1 - 5 , an aerial work vehicle for power maintenance in a wind farm, including a U-shaped hanging plate 1. A U-shaped sliding opening 2 is horizontally opened on the side wall of the hanging plate 1. U-shaped sliding plates 3 are symmetrically and slidably arranged in the sliding opening 2. One end of the sliding plate 3 located outside is fixedly installed with a mounting plate 4;

[0025] A mounting block is fixedly installed on the surface of the hanging plate 1. A rotating opening is opened on the surface of the mounting block. A threaded rod 5 with opposite thread directions at both left and right ends is horizontally rotatably installed in the rotating opening. Sliders 6 are symmetrically threaded on the threaded rod 5. Two L-shaped connecting rods 7 are fixedly installed on the surface of the slider 6. One ends of the two pairs of connecting rods 7 are respectively fixedly connected to the surfaces of the two mounting plates 4. Adjusting wheels are fixedly installed at both ends of the threaded rod 5, and anti-slip patterns are provided on the surface of the adjusting wheels;

[0026] By rotating the threaded rod 5, at this time, the two sliders 6 symmetrically threaded on the threaded rod 5 will respectively drive the two sliding plates 3 to move horizontally. During the movement of the two sliding plates 3, the total area of the sliding plates 3 and the hanging plate 1 will change, so that the number of people that the hanging plate 1 can carry is no longer fixed, improving the practicability.

[0027] Telescopic rods 8 are fixedly installed on the front and rear surfaces of the hanging plate 1. One end of the telescopic rod 8 is fixedly installed with a moving plate 9. Adsorption components are symmetrically arranged on the surface of the moving plate 9. The adsorption components are used to adsorb the sliding plates 3. The adsorption components include hollow rods 10 fixedly installed on the surface of the moving plate 9 and suction cups 11 fixedly installed at one end of the hollow rods 10. Two through openings 12 that are both connected to the sliding opening 2 are opened on the front and rear surfaces of the hanging plate 1, and the positions of the multiple suction cups 11 correspond to the positions of the multiple through openings 12;

[0028] The surface of the moving plate 9 is symmetrically provided with desorption components for releasing the adsorption of the suction cups 11. The desorption components include a rotating shaft 13 and a covering plate 14. Rotating ports are symmetrically formed on the surface of the moving plate 9 and penetrate through two hollow rods 10 respectively. The two rotating shafts 13 are respectively rotatably installed in the two rotating ports in a sealed manner. An air guide port 15 is formed on the surface of the hollow rod 10. The covering plate 14 is slidably and rotationally arranged in the hollow rod 10 and is used to cover the air guide port 15. One end of the rotating shaft 13 located inside the hollow rod 10 is fixedly connected to the covering plate 14 through a connecting rod. The rotating shaft 13 is connected to the moving plate 9 through an elastic component. The elastic component includes a torsion spring 16 sleeved on the rotating shaft 13. An installation block is fixedly installed at one end of the rotating shaft 13 located outside the environment. The two ends of the torsion spring 16 are respectively fixedly connected to the installation block and the moving plate 9;

[0029] When the threaded rod 5 is rotated to control the sliding plate 3 to move to a suitable position, at this time, the two telescopic rods 8 can be controlled to contract together, so that the multiple suction cups 11 respectively abut against the two sliding plates 3. Since the air guide port 15 formed on the surface of the hollow rod 10 is covered by the covering plate 14, when the suction cup 11 abuts against the sliding plate 3 and deforms, the gas in the suction cup 11 will flow out from the gap between the contact surfaces of the suction cup 11 and the sliding plate 3. Thus, the suction cup 11 will be attracted to the sliding plate 3, achieving the effect of locking the sliding plate 3 and enhancing the stability of fixing the position of the sliding plate 3;

[0030] When it is necessary to release the adsorption of the suction cup 11, as long as the rotating shaft 13 is rotated to control the covering plate 14 to rotate until it no longer covers the air guide port 15, at this time, the gas in the external environment will enter from the air guide port 15, thereby releasing the adsorption between the suction cup 11 and the sliding plate 3. Then, when the rotating shaft 13 is released, at this time, the rotating shaft 13 will quickly rotate and reset with the covering plate 14 under the elastic potential energy of the torsion spring 16, and the covering plate 14 will cover the air guide port 15 again.

[0031] In the present utility model, by rotating the threaded rod 5, the two sliders 6 symmetrically and threadedly sleeved on the threaded rod 5 will respectively drive the two sliding plates 3 to move horizontally. During the movement of the two sliding plates 3, the total area of the sliding plate 3 and the hanging plate 1 will change, so that the number of people that the hanging plate 1 can carry is no longer fixed, improving the practicability.

[0032] In the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", "linkage", "fixation" and other terms should be understood in a broad sense.

[0033] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
