Technical Field

[0001] This application relates to the technical field of ballast water systems, and in particular to a fouling cleaning device for a ballast water tank. Background Art

[0002] Generally speaking, the displacement of a cargo ship is different when loading and unloading goods. To ensure the safe navigation of the ship, ballast water is loaded and discharged according to the loading state of the ship during navigation. A ballast water tank refers to the cabin of a ship used to hold ballast water, which mainly plays the role of adjusting the center of gravity position, floating state and stability of the ship.

[0003] In related technologies, in order to reduce the problems of microbial invasion and pollution caused by ship ballast water, a filter screen is usually installed inside the ship to filter the ballast water first, so as to reduce impurities larger than the diameter of the filter screen holes from entering the ballast water tank along with the ballast water.

[0004] In view of the above related technologies, the inventor found that: due to the limitation of the mesh size of the filter screen, the filtering ability of the filter screen is limited, and certain impurities still enter the ballast water tank with the ballast water. The impurities inside the ballast water gradually precipitate and are liable to adhere to the inner wall of the ballast water tank to form dirt, thereby causing bacteria to breed and pollution to occur in the ballast water inside the ballast water tank, so it needs to be improved.
