Description

Technical Field

[0001] The utility model relates to the technical field of wind power device maintenance, in particular to a special wind power maintenance device. Background Art

[0002] As we all know, wind power generation involves converting the kinetic energy of wind into electrical energy. Wind is a pollution-free energy source, making it environmentally friendly and capable of generating enormous amounts of electricity. Consequently, more and more countries are prioritizing wind power generation. As a clean, renewable energy source, wind energy is gaining increasing attention worldwide. Its reserves are enormous. Globally, wind energy is estimated to be 2.74 million MW, of which 2 million MW is usable, ten times greater than the total amount of hydropower available on Earth. Wind has long been utilized—primarily through windmills for pumping water and grinding flour—but now, interest is growing in harnessing the power of wind. Because wind power generation requires the installation of large, massive wind turbines within wind farms, any malfunction requires maintenance personnel to access the turbines. Since these personnel must work at height, the tools they carry are crucial for maintaining wind turbines.

[0003] The wind power maintenance device disclosed in the publication number CN207834935U is retrieved. During the maintenance process, maintenance personnel are required to work at high altitude. However, when working at high altitude, the impact of birds on maintenance becomes very obvious. The swinging blades are used to swing, thereby expelling birds flying near the wind power equipment to be repaired; the bird-repelling teeth are set to prevent birds from landing, so as to avoid the impact of birds on maintenance work.

[0004] However, the wind power maintenance device disclosed in the above patent is extremely inconvenient for maintenance personnel to carry because of its large size and the sharp bird-repelling teeth. Utility Model Content
