[0002] At present, the maintenance of the hull surface mainly uses sandblasting and shot peening to remove paint and rust from the hull by hitting. That is, sandblasting and rust removal use compressed air as the power or high-pressure water below 40 Mpa to form a high-speed jet beam to spray the abrasive (garnet sand, copper ore sand, quartz sand, emery, iron sand, etc.) onto the surface of the workpiece at high speed, so that the old paint and rust on its surface fall off. Another method is to directly clean the hull surface with a handheld high-pressure water gun (pressure about 250 Mpa) standing on a telescopic aerial work platform. This operation method has a large labor intensity and low efficiency.

[0003] Most of the existing cleaning disc brackets on the market use the cooperation of guide rails and sliders for telescopic sliding. Due to the humid cleaning environment and the high corrosiveness of seawater, the traditional transmission method of guide rails and sliders is too precise and prone to failures, and when the spring is fatigued and broken, it may fly out and hurt the staff, so the use effect is not ideal.
