Technical Field

[0001] The utility model belongs to the technical field of wind power generation maintenance devices, and in particular relates to a station maintenance device for wind power generation. Background Art

[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. As people's environmental awareness continues to increase, wind energy has attracted people's attention as a renewable energy source with large energy storage capacity, cleanness and no pollution. At present, the main method used is to deploy wind turbines to use wind power to drive the windmill blades to rotate, and increase the speed through a speed increaser, so that the generator can generate electricity.

[0003] The daily maintenance of wind farms plays a vital role in the stable operation of wind turbines, reducing maintenance costs and extending equipment life. Therefore, wind turbines need to be regularly maintained during actual application. The maintenance items of wind farm production inspections mainly include: inspection and cleaning of towers, nacelles and blades, inspection and lubrication of machine parts, maintenance of data acquisition and monitoring systems, and inspection and maintenance of electrical equipment.

[0004] Among them, blades are an important part of wind turbines. In order to improve the efficiency of kinetic energy transmission of wind energy, the volume structure of wind turbine blades is generally designed to be larger, which makes the blades of wind turbines susceptible to rust, deformation, etc. due to their own structure and environment. In the daily maintenance of wind farms, maintenance personnel need to polish, spray and smooth the surface of the wind turbine blades.

[0005] However, since the blades of wind turbines are mainly installed on the outside of wind towers, when inspecting and cleaning the blades of wind turbines, maintenance personnel usually need to be suspended on the outside of the blades to inspect and clean the blades manually. Since the blades are generally large in size and require more tools during the inspection and cleaning process, the maintenance convenience and safety of wind farm blades are poor.

[0006] Therefore, in view of the above technical problems, it is necessary to provide a station maintenance device for wind power generation. Utility Model Content
