High-pressure rust removal device for ship pipeline rust removal

The high-pressure rust removal device comprises a high-pressure cleaning machine body, a water outlet of the high-pressure cleaning machine body is fixedly connected with a connecting pipe, the rear end of the connecting pipe is fixedly connected with a water inlet, and the bottom of the water inlet is fixedly connected with a high-pressure water pipe. The inner curved surface of the high-pressure water pipe is fixedly connected with a high-pressure nozzle, the two side ends of the high-pressure water pipe are fixedly connected with fixing rings, and the inner curved surfaces of the fixing rings are fixedly connected with limiting rings. The high-pressure water pipe is a circular-arc-shaped water pipe component, so that high-pressure water can be lapped to the outer curved surfaces of the lower ends of the universal rollers to be attached to the outer curved surface of a pipeline needing to be derusted after being lapped out from the high-pressure spray head, and rust covering the outer curved surface of the
