[0031] Working principle: When cleaning the bottom and side walls of the bulk cargo ship, the cleaning vehicle 1 moves forward, and water is sprayed to the front side of the cleaning vehicle 1 through the hose 35, the first-level branch pipe 34, the first-level hollow strip 31 and the first-level nozzle 32 to rinse and clean the ship's cabin. The sprayed water flows to the bottom of the concave extraction frame 41, and the fan 48 is turned on at the same time. With the help of the duct 49, the water is guided to the liquid storage tank 42 through the U-shaped notch 46, the transfer pipe 43, the hollow frame 44, and the second-level branch pipe 45 in sequence. Under the obstruction of the inclined baffle 410 and the longitudinal baffle 411, the water will not be directly sucked into the fan 48, so The water falls onto the secondary filter screen 47 more smoothly and is filtered by the secondary filter screen 47.

When the air passes through the gas flow sensor 62, if the air flow rate decreases, it means that a certain amount of residue is adsorbed on the bottom of the secondary filter 47, thereby blocking the secondary filter 47. The gas flow sensor 62 senses and transmits the data to the external terminal. The external terminal receives the data and controls the secondary drive motor 64 to start, so that the drive screw 67 rotates, so that the translation plate 65 drives the linkage plate 66 and the scraper 61 to move right, scraping the bottom of the concave extraction frame 41, and scraping off the residue adsorbed on the bottom of the secondary filter 47, ensuring the connectivity of the secondary filter 47, thereby ensuring the collection of water by the water utilization module 4; When the cleaning vehicle body 1 moves forward on the bottom and side wall of the bulk carrier cabin, the primary drive motor 24 is turned on to drive the rotating shaft 25 to rotate, so that the fan blades 22 rotate around the rotating shaft 25, and cooperate with the closed ring 26 to continuously extract the air in the closed ring 26 and the circular groove 21, so that the cleaning vehicle body 1 fits more closely to the cabin wall.
