[0029] refer to Figure 2 Three movable support rods 3 and two positioning support rods 4 are provided on the outer side of the first side plate 201. The three movable support rods 3 are arranged in a triangle, and the two positioning support rods 4 are located in the triangular area formed between the movable support rods 3. The movable support rods 3 and the positioning support rods 4 are respectively provided through the first side plate 201 and are threadedly connected to the first side plate 201.

[0030] Specifically, refer to Figure 1 A first threaded seat 33 is provided on the platform 2, and a first thread matching the first threaded seat 33 is provided on the movable support rod 3. The movable support rod 3 is threadedly connected to the first threaded seat 33. A rolling element 32 is provided at one end of the movable support rod 3 outside the platform 2. The rolling element 32 is configured to form rolling contact with the wall of the wind turbine tower 1. A first handle 31 is provided at one end of the movable support rod 3 inside the platform 2. The first handle 31 is used to rotate the movable support rod 3 and adjust the position of the movable support rod 3 and the rolling element 32.

[0031] Furthermore, a second threaded seat 43 is provided on the platform 2, and a second thread matching the second threaded seat 43 is provided on the positioning support rod 4, so that the positioning support rod 4 is threadedly connected to the second threaded seat 43. A positioning body 42 is provided at one end of the positioning support rod 4 outside the platform 2, and the positioning body 42 is used to form a positioning contact with the wall of the wind turbine tower 1.

[0032] refer to Figure 3 In this embodiment, a negative pressure chamber 423 is disposed within the positioning body 42. An adsorption plate 421 is disposed on one side of the negative pressure chamber 423. The adsorption plate 421 is configured to contact the wall of the wind turbine tower 1. The adsorption plate 421 is provided with multiple negative pressure holes 422, which connect the negative pressure chamber 423 with the exterior of the positioning body 42. The adsorption plate 421 can be adsorbed onto the wall of the wind turbine tower 1 through negative pressure, thereby securing the positioning body 42.

[0033] Furthermore, an adsorption cylinder 5 is fixedly mounted on the first side panel 201 of the platform 2. A piston 51 is disposed within the adsorption cylinder 5. The space below the piston 51 serves as an air intake space. The air intake space of the adsorption cylinder 5 is connected to the negative pressure chamber 423 of the positioning body 42 via an air duct 6. An air circulation hole is disposed above the piston 51. The upper portion of the piston 51 is fixedly connected to a piston rod 52.

[0034] Furthermore, a limit ring 55 is provided below the piston 51 , and the limit ring 55 is used to limit the lower limit position of the piston 51 to prevent the piston 51 from blocking the air inlet hole of the adsorption cylinder 5 , which is a hole connected to the air guide pipe 6 .

[0035] refer to Figure 1 and Figure 4 The platform 2 is provided with an isolation plate 23, which is located between the first side plate 201 and the second side plate 202 and parallel to the first side plate 201 and the second side plate 202. The first handle 31 and the second handle 41 are located between the isolation plate 23 and the first side plate 201. The isolation plate 23 is used to isolate the activity space of the maintenance personnel from the first handle 31 and the second handle 41 to prevent the maintenance personnel from accidentally touching the first handle 31 and the second handle 41 during activities.

[0036] refer to Figure 2 and Figure 4 A hanging seat 24 is also provided on the platform 2, and the hanging seat 24 is used to connect the hanging rope 7. The lower end of the hanging rope 7 is connected to the hanging seat 24, and the upper end of the hanging rope 7 is connected to the top of the wind turbine tower 1 or a high cable traction machine. The hanging rope 7 is used to pull the platform 2. By releasing and pulling the rope, the platform 2 can move along the wall of the wind turbine tower 1, so that the maintenance personnel can move relative to the wall of the wind turbine tower 1, which facilitates the maintenance of the wind turbine tower 1.

[0037] The platform 2 of the auxiliary platform for wind turbine generator maintenance in this embodiment is used to carry maintenance personnel to facilitate maintenance work inside the tower. Figure 6 When the platform 2 is in operation, the movable support rods 3 or the positioning support rods 4 of the platform 2 are used to support the wall of the wind turbine tower 1. The suspension ropes 7 are used to hold the platform 2 at a height. By releasing and pulling the ropes, the platform 2 can move along the wall of the wind turbine tower 1.

[0038] When the platform 2 is being maintained at a fixed position, the second handle 41 is turned to adjust the position of the positioning support rod 4 and the positioning body 42 so that the positioning body 42 contacts the wall of the wind turbine tower 1, and then the third handle 54 is rotated forward to generate negative pressure inside the negative pressure chamber 423 of the positioning body 42. The adsorption plate 421 can be tightly attached to the wall of the wind turbine tower 1, which is used to position the platform 2 and facilitates stable operation by maintenance personnel.

[0039] When the platform 2 needs to be moved, the third handle 54 is rotated in the opposite direction to contact the adsorption of the positioning body 42, and then the second handle 41 is turned to separate the positioning body 42 from the wall of the wind turbine tower 1. Finally, the first handle 31 is turned to adjust the position of the movable support rod 3 and the rolling body 32 so that the rolling body 32 contacts the wall of the wind turbine tower 1, forming a rolling body 32 that can roll against the wall of the wind turbine tower 1, thereby facilitating the movement of the platform 2.

[0040] The positions of the movable support rod 3 and the positioning support rod 4 of the auxiliary platform for repairing wind turbines in this embodiment are adjusted by threaded connections, and the adsorption cylinder 5 also generates negative pressure by adjusting the position of the piston 51 through threads. The adjustment method is simple and convenient, low in cost, and does not require the aid of other driving equipment, and is suitable for outdoor aerial operations.
