[0002] A wind turbine is a power device that converts wind energy into mechanical work. The mechanical work drives the generator rotor to rotate, and finally outputs alternating current. A wind turbine generally consists of components such as a wind wheel, a generator, a yaw regulator (tail fin), a tower, a speed limit safety mechanism, and an energy storage device. The working principle of a wind turbine is relatively simple. The wind turbine blades rotate under the action of wind, converting the kinetic energy of the wind into the mechanical energy of the main shaft and the gearbox. The generator rotates to generate electricity driven by the wind turbine shaft. The gearbox of the wind turbine is installed on the base through a support base.

[0025] Specifically, the support seat of the wind turbine to be processed is placed on the upper end of the workbench 1. Then, the sandblasting mechanism 4 works, so that the liquid abrasive is ejected from the sandblasting end of the sandblasting mechanism 4, thereby performing sandblasting treatment on the surface of the support seat of the wind turbine. While the sandblasting mechanism 4 is working, the swinging mechanism 5 works to drive the sandblasting end of the sandblasting mechanism 4 to swing, thereby expanding the sandblasting range and improving the sandblasting effect on the surface of the support seat of the wind turbine. At the same time, under the cooperation of the moving mechanism 3, the sandblasting end of the sandblasting mechanism 4 is driven to move, thereby realizing sandblasting treatment on different parts of the support seat of the wind turbine, without the need for manual operation with a spray gun, thus reducing the labor intensity of the staff.
