Underwater cleaning robot for outer wall of ship

Abstract

The invention discloses an underwater cleaning robot for the outer wall of a ship. The underwater cleaning robot comprises a robot body; the cleaning brush assembly is mounted at the front end of the robot main body through a mechanical arm; the camera is used for shooting the cleaning range of the cleaning brush assembly; the cavitation bubble device is arranged in the robot main body and emits high-pressure cavitation bubbles to the cleaning range through a propelling nozzle mounted at the front end of the robot main body; the spraying assembly is used for spraying the cleaned area when the coating of the outer wall of the ship is damaged after cleaning is completed; the four permanent magnet universal wheel assemblies are arranged on the two sides of the bottom of the robot body correspondingly and used for being attracted to the outer wall of the ship and driving the robot body to move. The robot firstly adopts a cleaning brush and then adopts a cavitation device for cleaning, so that the loss of the outer wall coating of the ship can be reduced. And by arranging the spraying assembly, repairing and spraying can be conducted in time after the coating is lost, and seawater is prevented from corroding the damaged position of the coating.

Description

Technical field [0001] The present invention relates to the field of underwater robots, particularly to a ship outer wall underwater cleaning robot. Background [0002] With the advent of the era of marine economy, ships as an indispensable tool for maritime navigation, hull protection issues have gradually been paid attention to, the hull surface is immersed in the ocean all year round, the seawater is rich in minerals and salt corrosive, and the biological adhesion ability in the ocean is strong, so the hull that travels below sea level all year round will adhere to a large number of marine organisms and dirt, greatly increasing ship resistance, increasing additional fuel consumption, seriously delaying the sailing period, increasing operating costs, and shortening the service life of ships. [0003] Because the hull surface attachment is hard and thick, most of them use high-pressure water jet devices to clean, which is easy to remove the surface anti-rust material; the third ...

AI Technical Summary

Problems solved by technology

[0003] Due to the hard and thick attachments on the surface of the hull, high-pressure water jets are mostly used for cleaning, which is easy to remove surface anti-rust materials; third, the removal of attachments on the outer wall of the hull is mainly manual work. Due to the high impact force of high-pressure water jets, The water outlet pressure is about 75-100MPa, which poses a certain threat to the safety of divers
