Description

Technical Field

[0001] The invention relates to the technical field of ship cargo cleaning, and in particular to a ship cargo cleaning robot. Background Art

[0002] Ship is a general term for various vessels. Ship is a means of transportation that can sail or anchor in waters for transportation or operation. It has different technical performance, equipment and structural types according to different use requirements. Ship is a man-made means of transportation that mainly operates in geographical waters. In addition, civilian ships are generally called ships, military ships are called warships, and small ships are called boats or boats. They are generally called ships or boats. The interior mainly includes accommodation space, support structure and drainage structure, and has a propulsion system that uses external or self-contained energy.

[0003] The patent network announcement number CN 114516388 A discloses an underwater cleaning robot for the outer wall of a ship, which includes: a robot body; a cleaning brush assembly, which is installed at the front end of the robot body through a mechanical arm; a camera for photographing the cleaning range of the cleaning brush assembly; a cavitation device, which is arranged inside the robot body and emits high-pressure cavitation to the cleaning range through a propulsion nozzle installed at the front end of the robot body; a spraying assembly, which is used to spray the cleaned area when the coating of the outer wall of the ship is damaged after cleaning; four permanent magnetic universal wheel assemblies, which are respectively arranged on both sides of the bottom of the robot body, for adsorbing on the outer wall of the ship and driving the robot body to move. The robot first uses a cleaning brush and then uses a cavitation device to clean, which can reduce the loss of the coating on the outer wall of the ship. By configuring the spraying assembly, the coating can be repaired and sprayed in time after loss, avoiding seawater from corroding the damaged coating.

[0004] The applicant believes that the following shortcomings exist: when the cleaning disc of the underwater cleaning robot for the outer wall of a ship is cleaning the object to be cleaned, since the cleaning disc itself does not have the function of swinging left and right and up and down, the cleaning disc can only clean a part of the surface of the object to be cleaned, which narrows the cleaning range and reduces the cleaning effect on the object to be cleaned.
