Description

Wind turbine blade cleaning device

Technical Field

The utility model relates to the technical field of wind power generation, in particular to a cleaning device for wind power generation blades.

Background technique

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. A wind turbine generally consists of a wind rotor, a generator (including a device), a direction regulator (tail wing), 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, and it converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft. The generator rotates and generates electricity driven by the wind rotor shaft. Broadly speaking, wind energy is also solar energy, so it can also be said that a wind turbine is a heat energy generator that uses the sun as a heat source and the atmosphere as a working medium.

Wind power generation adopts a windmill-like power generation mode. Because wind turbine blades are often in an outdoor state, a lot of dust will accumulate on the blades during long-term operation, especially on the edges of the blades. This increases the weight of the wind turbine blades, which will affect the entire power generation system over time, thereby affecting normal operation. Therefore, the wind turbine blade cleaning device can effectively clean the dust on the surface of the wind turbine blades.

The existing patent (publication number: CN214184275U) discloses a blade cleaning device for a wind turbine, which belongs to the technical field of wind turbines, and includes a ground, and a water tank is fixedly installed on the upper end of the ground. The utility model uses a first electric telescopic rod to extend and retract, so that the fixing clamp is adjusted to fit the length of the wind turbine blade. By placing the wind turbine blade into the fixing clamp, the second electric telescopic rod is used to extend and retract, and the wind turbine blade is fixed inside the fixing clamp by a fixing plate. The rubber properties of the lower end of the fixing plate and the lower end of the fixing clamp are used to prevent the fixing clamp from damaging the surface of the wind turbine blade. When the wind turbine blade is fixed, a cleaning brush is used to clean it. When one side of the wind turbine blade is cleaned, an electric turntable is used to rotate, and the uncleaned surface of the wind turbine blade is rotated upward for cleaning, so that the wind turbine blade cleaning device is more convenient to use. In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. The traditional wind turbine blade cleaning device requires the blades to be disassembled and placed in the cleaning device for cleaning. Due to the large size of the blades, a large amount of manpower and material resources are required during the disassembly process, which greatly increases the labor intensity of the staff, thereby reducing work efficiency; 2. After cleaning one side of the traditional wind turbine blade, the blade needs to be turned over before the other side can be cleaned. It is impossible to clean both sides of the blade simultaneously. The cleaning process is relatively cumbersome, thereby greatly reducing the cleaning efficiency of the wind turbine blades.
