Description
Technical Field
[0001] The utility model relates to the technical field of wind power generation, in particular to a wind power generation blade cleaning device. Background Art
[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. The working principle of a wind turbine is relatively simple. The wind wheel rotates under the action of wind force, and it converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. The generator rotates and generates electricity driven by the wind wheel shaft. The power generation blades that drive the wind wheel shaft to rotate are the most basic and critical components of a wind turbine. Its good design, reliable quality and superior performance are the decisive factors to ensure the normal and stable operation of the unit.
[0003] Wind turbine blades are one of the core components of wind turbines that convert wind energy into electrical energy. However, since the operating environment of wind turbines is often harsh, they are often affected by a series of factors such as wind, sand, flying birds, oil, salt spray, ice and snow, which causes the surface of the blades to be eroded, which can easily lead to a decrease in the moisture, corrosion and radiation resistance of the blade surface, affect the aesthetics of the blades, reduce the power generation efficiency of the blades, and shorten the service life of the blades.
[0004] At present, the main way to clean wind turbine blades is manual cleaning. Workers use safety ropes to rise or descend in the air, spray detergent and water, and then use a brush to clean the attached dust and impurities to ensure the cleanliness of the blades. However, this method is relatively dangerous, and because the blade shape is an irregular curved surface and the surface area is large, the efficiency of manual cleaning is low. Utility Model Content
