[0026] Working principle:

[0027] When the sand blasting robot 1 and the sand supply device 2 are moved to the cleaning position, the robot is adsorbed on the surface of the ship, the brush is abutted against the surface of the ship, the recovery chamber 14 is relatively sealed, the high-pressure sand blasting pump is started, the sand in the sand supply tank is supplied to the sand supply gun 9 through the sand supply pipe 3, the sand is sprayed on the surface of the ship, the impurities and rusted objects on the surface of the ship are knocked down and cleaned, and then the sand and impurities fall into the recovery chamber 14. At the same time, the negative pressure fan 26 works to enable the sand return pipe 4 to generate negative pressure, so that the sand and impurities automatically enter the sand return pipe 4 and then enter the recovery tank 22. When the sand and impurities enter, they fall on the filter screen, the filter screen filters the large sand and drops to the bottom of the recovery tank 22, then the dust and small impurities enter the fixed box 28, then enter the filter pipe 24, then enter the filter cartridge 25, and then are discharged after being filtered by the filter core 202 in the filter cartridge 25, so as to ensure that the tail gas emission does not pollute the air. When the sand in the recovery tank 22 is recovered to the position, the one-way valve 201 is manually opened, the sand falls into the sand supply tank, and then the sand supply operation is repeated. The robot moves on the surface of the ship and continuously cleans, so as to clean the rust and impurities on the surface of the ship. Compared with the traditional manual operation, the intelligent and automatic cleaning is realized, which is convenient for the staff to operate. Compared with the traditional high-pressure water gun, the iron sand cleaning can prevent the ship surface from being rusted by water after cleaning, so as to protect the ship surface and improve the practicability of cleaning.
