Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ship cleaning, in particular to a marine attachment cleaning device for marine engineering equipment of a ship. BACKGROUND

[0002] Because ships sail and berth in the sea all the year round, various marine organisms such as algae and barnacles will attach to the underwater part of the ship. On the one hand, these attachments will continuously erode the paint and damage the surface coating of the ship body during the formation process, leading to more serious corrosion of the ship surface. On the other hand, the attachments will increase the weight of the ship body, affecting the sailing speed and increasing fuel consumption.

[0003] For small ships, they can be towed into a dock for cleaning. For large cargo ships, it is difficult and increases the cost of downtime to tow them into a dock, so most cleaning methods are manual diving cleaning. This method requires workers to dive underwater, which is very demanding for workers and not only poses a risk to their lives, but also has high costs and low efficiency.

[0004] There are already devices on the market for cleaning the surface of a ship. Announcement No. CN112027012A provides a ship bottom cleaning underwater robot, which includes a shell, an electromagnet, a universal wheel, a first motor, a grinding disc, and a high-pressure cleaning machine. The robot uses high-pressure cleaning and grinding disc cleaning to clean the parasites together, and uses electromagnetic adsorption to attach to the surface of the ship body. Announcement No. CN212022925U discloses a magnetic adsorption ship body cleaning robot, which includes a shell, a crawling structure, a cleaning structure, and a control device. When in use, the device is adsorbed to the surface of the ship by magnetic force to clean the ship body. Because the surface of the ship is not smooth or regular, the adsorption ability is weak when adsorbed to the surface of the ship body, which easily falls off and affects normal cleaning work.
