Wind energy is a clean and pollution-free renewable energy source that has been utilized by people for a long time. It is mainly used to pump water and grind flour through windmills. What people are interested in is how to use wind to generate electricity. Using wind power generation is very environmentally friendly, and the wind energy reserve is huge. Therefore, it has been increasingly valued by countries around the world. The blade is the most basic and crucial component in a wind turbine. Its good design, reliable quality, and excellent performance are the decisive factors to ensure the normal and stable operation of the unit. Due to the harsh environment and continuous operation for a long time, according to the publication number CN218407689U, there is disclosed a cleaning device for a wind turbine blade, including a generator.
