At the same time, as the steel rope 5 moves upward when tightened, the impurities on the surface of the steel rope 5 can be cleaned through the continuous rotation of the grinding ring 10, which solves the problem that the steel rope 5 is easily attached to the surface of the steel rope 5 due to a large amount of impurities attached to the surface of the steel rope 5 when it is immersed in water for a long time, resulting in the inability to tighten the steel rope 5 due to the clogging of the connecting hole by impurities when the steel rope 5 is tightened. The problem is solved, and the impurities attached to the surface of the steel rope 5 can be cleaned by continuously rotating the grinding ring 10, which greatly enhances the service life of the equipment. By pouring wire rope grease into the supply nozzle 17, and then moving the push plate 16 forward by the supply hydraulic rod 15, the wire rope grease inside the supply nozzle 17 can be squeezed into the surface of the steel rope 5, and then the coating structure 19 is continuously moved up and down on the surface of the steel rope 5 by the lifting hydraulic rod 18, so that the wire rope grease can be evenly coated on the surface of the steel rope 5, which solves the problem that the steel rope 5 is prone to rust during penetration, resulting in the steel rope 5 being unable to slide smoothly and tighten inside the connecting hole, and achieves the effect of evenly coating the surface of the steel rope 5 with wire rope grease after cleaning it for maintenance, which greatly The service life of the steel rope 5 is greatly enhanced. The gate body 6 is lifted to drain the water and then the gate body 6 is lowered to the bottom. The cleaning hydraulic rod 23 is used to move the base 24 downward until the cleaning roller 26 is in contact with one side of the gate body 6. The cleaning roller 26 is driven by the cleaning motor 25. At the same time, the moving motor 20 drives the moving lead screw 21 to drive the slider 22 to move the cleaning roller 26 to the right. The attachments and rusted positions on the surface of the gate body 6 can be polished and cleaned, which solves the problem that a large amount of impurities are attached to the surface of the gate and the surface is rusted due to long-term immersion in water, resulting in the gate being unable to rise and fall. The effect of polishing and cleaning the attachments and rusted positions on the surface of the gate is achieved, which greatly enhances the service life of the gate. The gate body 6 After the cleaning is completed and the surface of the gate body 6 is dried, the hydraulic rod 27 is driven to move the nozzle seat 28 downward, and the liquid paint in the spray box 32 is pumped into the nozzle seat 28 through the hose 30 through the water pump 31, and then the paint is sprayed on the surface of the gate body 6 through the nozzle seat 28 and the spraying structure 29.
