The invention relates to a ship rust-removing hand-held type wall-climbing robot device based on high pressure water jet. The ship rust removing hand-held type wall-climbing robot device based on highpressure water jet comprises a housing, a shaft ring, a vacuum pipe mounting sleeve openings, an inlet liquid guide disk, a high pressure pipe supporting sleeve, a high pressure pipe upper sleeve opening, a high pressure pipe lower sleeve opening, rivets, bolts, a high pressure pipe mounting sleeve opening, an elastic sealing ring, a T-shaped liquid guide pipe, bearings, a universal ball, an endcover, a drainage pipe, a cover, a rotating fan blade, nozzles, a cylinder and a permanent magnet. The whole ship rust removing hand-held type wall-climbing robot device based on high pressure water jet is divided into an integral vehicle driving part and a high pressure water jet rust removing part; the driving mode of the integral vehicle driving part is manual hand-held driving, and the ship rust removing hand-held type wall-climbing robot device based on high pressure water jet climbs on the surface of the ship under the coordination of the universal ball and the permanent magnet; and theliquid in the high pressure water jet rust removing part passes through the inlet liquid guide disk, enters into the drainage pipe after being rectified by the T-shaped liquid guide pipe, is drained to each nozzle through the drainage pipe, and is sprayed to the surface of rust after being rectified in the nozzles to remove the rust on the surface of the ship.
