The chassis is also provided with a recovery tank 22, the upper end of the recovery tank 22 is connected to the return sand pipe 4, and the lower end of the recovery tank 22 is connected to the sand supply tank 21. A manually opened and closed one-way valve 201 is provided between the recovery tank 22 and the sand supply tank 21.

[0024] In order to facilitate the movement of the chassis and facilitate the staff to clean various places on the ship, movable universal wheels 5 are provided at the bottom of the chassis.

[0025] Working principle:

[0026] During use, when the surface of the ship needs to be cleaned for rust removal and impurity removal, the sandblasting robot 1 and the sand supply device 2 are moved to the cleaning position, and then the robot is adsorbed on the surface of the ship so that the brush resists the surface of the ship, thereby making the recovery chamber 14 relatively sealed, and then the high-pressure sandblasting pump is started, and the sand in the sand supply tank is supplied to the sand supply gun 9 through the sand supply pipe 3, and the sand is sprayed on the surface of the ship, thereby knocking down and cleaning the impurities and rusty objects on the surface of the ship, and then the sand and impurities fall into the recovery chamber 14. At the same time, the negative pressure blower 26 works to make the sand return pipe 4 produce negative pressure, so that sand and impurities automatically enter the sand return pipe 4 from the recovery pipe 41 and enter the recovery tank 22. When the sand and impurities enter, they fall on the filter screen, which filters the large sand and drops it to the bottom of the recovery tank 22. Then, dust and fine impurities enter the filter pipe 24 through the fixed box 28, and then enter the filter cartridge 25 from the filter pipe 24. After being filtered by the filter core 202 in the filter cartridge 25, they are discharged, thereby ensuring that exhaust gas emissions do not pollute the air. When the sand in the recovery tank 22 is recovered to its proper place, the one-way valve 201 is manually opened so that the sand falls into the sand supply tank and is then reused, thus performing repeated sand supply operations. The robot continuously moves on the surface of the ship through the moving wheels and continuously cleans, thereby removing the rust and impurities on the surface of the ship. Compared with traditional methods, manual operation is avoided, intelligent automatic cleaning is realized, and it is conducive to the operation of the staff. Compared with the traditional high-pressure water gun cleaning, the use of iron sand will prevent the surface of the ship from producing yellow rust due to water corrosion after cleaning, which is beneficial to protecting the surface of the ship and improving the practicality of cleaning.
