Description

Technical Field

[0001] The present invention relates to the technical field of ship cleaning equipment, in particular to an underwater cavitation cleaning system for ships. Background Art

[0002] As soon as a ship enters the water and comes into contact with seawater, bacteria immediately attach to the hull. This process only takes a few minutes but is irreversible. These attached bacteria cannot be washed away by the current. In the next few hours, the number of bacteria begins to grow exponentially. After a few days, a layer of biofilm like green mud will form on the hull. At this time, the pollution of the hull has really begun. This biofilm is like a key that opens the door for other marine organisms to attach, such as barnacles. Once the hull is polluted, the efficiency of the ship is reduced, and fuel consumption increases significantly due to the increase in water resistance. Keeping the hull and propeller in the best clean state can save a lot of fuel, increase endurance, reduce engine wear, and increase the life of the steering gear and propeller. For this reason, it is necessary to use underwater cleaning equipment to clean impurities on the bottom of the ship.

[0003] In the prior art, to improve the stability of ships during long voyages, cavitation cleaning of impurities on the ship's bottom is performed using handheld high-pressure water guns and ship cleaning robots. However, when using cavitation cleaning devices to clean impurities from the ship's bottom, the robot's size is often relatively fixed, while ships vary in size. This results in the robot's cleaning quality being reduced due to the varying amounts of impurities adsorbed on the ship's bottom when cleaning ships of different tonnages. This also results in poor adaptive monitoring and adjustment of the cavitation effect and water pressure intensity generated by the cleaner, reducing the robot's flexibility in adjusting cleaning for ships of different tonnages, the cleanliness of impurities removed, and the cleaning quality of the cleaning device for ships of different tonnages.
