Underwater robot for ship cleaning

Abstract

The invention discloses an underwater robot for ship cleaning. The underwater robot comprises a machine frame, a shell arranged on the machine frame, a cleaning unit arranged on the machine frame anda driving unit arranged on the machine frame, an indicating and positioning unit used for dividing a ship into a plurality of cleaning areas is further arranged on the shell, and the indicating and positioning unit comprises a starting device provided with at least two starting point positioners, an ending device provided with at least two end point positioners, a first mechanical arm used for containing the starting point positioners and a second mechanical arm used for containing the end point positioners. According to the underwater robot for ship cleaning, the surface of the ship is divided into the separate cleaning areas, so that when the robot is used for cleaning, the obstacle in the advancing process is small, the movement is stable, the cleaning effect of the robot is good, and the cleaning efficiency of the robot is improved.

Description

technical field [0001] The invention belongs to the technical field of ship cleaning, in particular to an underwater robot used for ship cleaning. Background technique [0002] During the entire operation period of the ship, there will be marine organisms attached to the ship wall, bottom, and even the propeller, especially when the ship is docked at the port, wharf or anchorage, various marine organisms (including animals, plants and microorganisms, etc.) Quickly attach and grow on the bottom surface of the ship, a thick layer of marine biofouling will be formed on the hull below the waterline of the ship. These marine biofouling layers are mainly composed of algae and shellfish attachments. [0003] As time goes on, the amount of attachment of these marine organisms will increase, which will have many adverse effects on the ship's navigation status and even operational safety. The attachment of marine organisms to the hull increases the weight of the ship and affects the s...

AI Technical Summary

Problems solved by technology

[0006] Robots for cleaning marine organisms on the surface of ships have appeared on the existing market, but since the surface of the ship is not a flat ideal plane, except for the edges of the ship, large single-body ships usually have a gradual convex arc surface, while two-body The surface of the ship and trimaran is more complicated; when the shape of the ship is unknown or inaccurate, it is difficult to obtain the cleaning line in advance. After the ship is repaired, it is difficult for the underwater robot to pass through the repaired part of the outer wall or the high welding seam. , escalators or other equipment welded to the ship's wall make it difficult for underwater robots to automatically pass through, so it is impossible to thoroughly clean the surface of the ship
