Description

Technical Field

[0001] The utility model belongs to the technical field of wind turbine cleaning, in particular to a cleaning device for a large wind turbine. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. A wind turbine generally consists of components such as a wind rotor, a generator, a rectifier, a tower, a speed limit safety mechanism, and an energy storage device. The working principle of a wind turbine is relatively simple. The wind rotor rotates under the action of wind force, and it converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft. The generator rotates and generates electricity under the drive of the wind rotor shaft. After long-term use, large wind turbines will be contaminated with a layer of dust or dirt on the surface. If the blades of the wind turbine are to be recycled, they need to be removed for repair and cleaned first to check for damage.

[0003] The utility model with the publication number of "CN209430347U" and the name of "An overlapping cleaning device for a large wind turbine" discloses a cleaning device for blades, which mainly drags the first fixed mobile fixture by contracting the hydraulic cylinder, and then the device moves from one end of the blade to the end of the blade for cleaning when this step is repeated. The device mainly cleans one side of the blade and cannot clean both sides of the blade at the same time, resulting in low cleaning efficiency. Utility Model Content

[0004] The utility model aims to provide a cleaning device for a large wind turbine. Through the function of a cleaning plate, the device can flexibly clean both sides of a blade through a cleaning plate with an adjustable spacing. Both sides of the blade can be cleaned at the same time, thereby improving the cleaning efficiency of the blade and being able to clean blades of different thicknesses. This makes the application range of the device wider and solves the problem that the existing device mainly cleans one side of the blade and cannot clean both sides of the blade at the same time, resulting in low cleaning efficiency.
