[0037] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0038] During operation, when a ship needs to be cleaned, the driving pulley 1 is started. The driving pulley 1 drives the ship bottom cleaning bin 2 to move to the water side. The staff starts the ship to move to the side wall of the conveyor belt 32 and starts the conveyor belt 32. The conveyor belt 32 drives the ship to move and convey it. The conveyor belt 32 moves the side wall of the ship to the top of the friction conveying rollers 37. The first connecting plate 35 is started.

When the cleaning of the bottom of the ship by the cleaning roller 46 is completed, the first transmission shaft 45 drives the oil brushing roller 481 to rotate through the small gear 49, the large gear 491 and the rotating round rod 48. The oil brushing roller 481 recoats the damaged protective paint surface at the bottom of the ship to avoid damage to the ship due to long-term immersion in water and extend the service life of the bottom of the ship;

[0040] When the impurities and water at the cleaning area of the water spraying cross plate 42 and the cleaning roller 46 fall into the bottom of the inner wall of the ship bottom cleaning bin 2 under the influence of gravity, the mixture of impurities and water is input into the internal of the screening pipe 52 through the drain pipe 50. Start the second drive motor 51. The second drive motor 51 drives the spiral conveyor pipe 54 to rotate through the second transmission shaft 53 to convey and discharge the mixture of impurities and water. Through the settings of the screening plate 57 and the water filtering holes 58, water is discharged from the inside of the water filtering holes 58 under the influence of gravity. The spiral conveyor pipe 54 continues to convey barnacles and other impurities, so that the equipment can automatically separate the cleaning water from barnacles and other impurities. When the spiral conveyor pipe 54 rotates, it drives the cleaning brush 55 to rotate.
