The impurities after washing are then shaken and filtered to increase the filtering area and improve the filtering quality. At the same time, the filtered impurities are collected to prevent them from flowing back into the water body again. The scale of different thicknesses is then adaptively adjusted for grinding through the adjusting component, which increases the grinding force and improves the grinding quality.

[0037] Working principle: First, the device is placed in the water body, and the kinetic energy of the second motor 301 drives the large rotating wheel 302 to rotate, and then the small rotating wheel 304 is driven to rotate by meshing with the crawler 303, so that the rotation of the small rotating wheel 304 and the large rotating wheel 302 drives the crawler 303 to rotate to move the device;

[0038] Then, the first cylinders 214 around the housing 100 drive the protective sleeves around to move outward, drive the multiple protective plates 215 to move outward, and then the protective plates 215 are pressed against the bottom wall of the pool by the spring, so as to surround the housing 100 and gather the local water flow to a certain extent;

[0039] During the movement of the device, the sponge roller 213 is driven to rotate to scrape off the impurities on the inner wall, and then the kinetic energy of the first motor 202 is used to drive the rotating shaft 204 to rotate, thereby driving the rotating sleeve 208 to rotate, and driving the grinding disc 209 to rotate, so as to grind the hard materials such as scale that adheres firmly to the inner wall to break them into powder state, and then the grinding disc 209 is adaptively floated up and down by the multiple damping rods 210 and springs, so as to adaptively grind scales of different thicknesses and increase the grinding force;

[0040] The rotation of the rotating shaft 204 drives the turbofan 205 to rotate, thereby forming a certain negative pressure for upward suction on the through hole and the inside of the filter cartridge 203, thereby sucking the impurities and scale and other hard materials after grinding and scraping, through the multiple suction holes 211 opened on the grinding disc 209, the multiple suction holes 211 are arranged downwardly at an angle, so that during the rotation of the grinding disc 209, an inward centripetal force is formed between the multiple suction holes 211, thereby increasing the adsorption force on impurities, and making the impurities move more concentratedly to the positions of the multiple suction holes 211, preventing a large amount of impurities from flowing chaotically in the water body, and then the impurities that are not adsorbed in the surroundings are sucked out through the suction pipe 212 Secondary adsorption is performed to improve the ability of impurity adsorption and collection. Then, through the rotation of the turbofan 205, a certain negative pressure is formed inside the overflow cylinder 216, and the adsorbed impurities are adsorbed and collected in the filter cylinder 203. The filter cylinder 203 is then used to filter the impurities so that they are filtered in the filter cylinder 203. Then, the filtered water flows through the multiple filter holes on the side wall of the filter cylinder 203 under the action of negative pressure into the pumping chamber 217 below the overflow cylinder 216, and then through the pumping hole in the middle position of the partition 218, the water in the pumping chamber 217 is sucked into the drainage chamber 219 above, and then the water is discharged through the multiple water outlet holes on the side wall of the drainage chamber 219.

[0041] Then, the baffle 306 is pulled upward by the second cylinders 305 on both sides, so that the overflow ports on both sides are opened and closed, and the sucked water flows out from the overflow ports on both sides. When the device moves to one side, the overflow port on the corresponding side is closed, and the overflow port on the other side is opened, so that the water overflows, thereby providing a certain driving force for the movement of the device and saving the kinetic energy of the active movement of the device.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
