Description

Technical Field

[0001] The present application relates to the technical field of wind power generation, and in particular to a wind power generation blade cleaning device. Background Art

[0002] Wind power equipment is equipment that uses wind energy to generate electricity or wind power. Wind turbine blades are the core components of wind power equipment that convert natural wind energy into electrical energy for wind turbines. The operating environment of wind turbine blades is often relatively harsh, and they are often affected by a series of factors such as wind and sand, flying birds, oil stains, flying insects, acid rain, salt spray, ice and snow, which lead to a decrease in various indicators such as moisture resistance, corrosion resistance, and radiation resistance on the blade surface. Therefore, the wind turbine blades should be cleaned regularly or irregularly as required.

[0003] According to the announcement number: CN220302270U, ​​a wind turbine blade cleaning device is disclosed. This technology discloses "including four fixed blocks and two clamping blocks, the outer walls of the two corresponding fixed blocks are respectively connected to two rotating rods through shaft rotation, the outer walls of the rotating rods are connected to the other two fixed blocks through shaft rotation, and the middle of the two corresponding fixed blocks and the two clamping blocks are respectively connected to two wrapping wheels through shaft rotation, which has the technical effects of not requiring manual work to fix the cleaning device, performing semi-wrapped cleaning on the blades, and fully cleaning the blades by moving up and down".

[0004] With respect to the above-mentioned related technologies, the inventors believe that the cleaning effect of the existing devices for cleaning wind turbine blades is poor. Generally, a cleaning brush is used to clean the surface of the turbine blades. This cleaning method has a poor cleaning effect and does not have a water spray mechanism, which makes it inconvenient to quickly rinse the surface of the turbine blades by spraying water. Secondly, when cleaning the surface of the turbine blades, the cleaning nozzles are generally set at a fixed angle. The nozzles set at a fixed angle are not conducive to better flushing the surface of the turbine blades, thereby reducing the use effect of the cleaning device. Utility Model Content

[0005] The purpose of the present application is to provide a wind turbine blade cleaning device to improve the problem of facilitating rapid flushing of the surface of the turbine blade by spraying water and being unfavorable for better flushing of the surface of the turbine blade.

[0006] The wind turbine blade cleaning device provided in this application adopts the following technical solution:
