Ship wall cleaning robot based on bearing magnetic attraction device

The invention discloses a ship wall cleaning robot based on a bearing magnetic attraction device. The ship wall cleaning robot comprises a robot shell, and a first high-pressure water pump and a second high-pressure water pump are mounted at the top of the robot shell; the driving control assembly is arranged in the robot shell and used for controlling operation of the mechanical driving assemblies, the mechanical driving assemblies are arranged on the two sides of the robot shell, and the mechanical driving assemblies enable the robot to be attached to the surface of the ship wall through small direct-current suction cup electromagnets; and the driving direction changing assembly is arranged at the bottom of the robot shell and used for controlling the robot to move in a direction changing mode. According to the robot, bearing magnetic attraction devices are adopted at leg transmission mechanisms, so that the robot can be attracted to the curved surface of the ship wall to the maximum extent, and when the sh
