Wind energy is renewable clean energy, wind power generation belongs to clean energy, and wind power generation is an important means for relieving energy shortage and environmental pressure. Wind power plants are generally built on open fields and where sufficient wind stability is obtained, such as mountainous or seaside. Existing wind power plants generally comprise: wind direction detection sensor, air duct, connection carousel, generator and generator tower. The air duct is formed by welding multiple air intercepting ducts together, and the height of the air duct is as high as 30-100 meters. The length of the single-section wind tube is generally several meters, and the single-section wind tube is firstly manufactured during factory production; then hoisting and splicing the single wind intercepting cylinders together, and welding the spliced seams to form a double wind intercepting cylinder or a longer wind barrel structural member; and finally, carrying out sand blasting, polishing, sand blasting and other operation processes on the air duct structural member. In order to ensure that the surface of the air duct has good cleanliness and roughness, the surface of the air duct needs to be subjected to pretreatment such as rust removal, sand blasting and the like.
