[0025] Furthermore, the base 1 is provided with a bearing plate 11, and four movable wheels 12 are fixedly provided at the bottom of the bearing plate 11;

[0028] During operation, the components on the top are supported by the support plate 11, which helps to ensure the overall stability during operation.

[0029] Furthermore, a collecting pipe 27 is fixedly installed on one side of the second pump 26, and a water storage tank 13 is fixedly installed on the other end of the collecting pipe 27;

[0030] During operation, the second pump 26 is driven to generate suction force on the inside of the centrifugal drum 32 through the connecting pipe 25, so that water inside the centrifugal drum 32 is extracted, and the extracted water is collected and stored by the collecting pipe 27.

[0031] Furthermore, a torque motor 29 is fixedly installed on the top of the fixed frame 28, a transmission shaft 31 is fixedly installed on the output end of the torque motor 29, a centrifugal drum 32 is fixedly installed on the other end of the transmission shaft 31, a sealing ring 36 is movably installed on one side of the centrifugal drum 32, and a connecting plate 24 is fixedly installed on the other side of the sealing ring 36;

When the silt and debris move to the top, they will contact the scraper 34, and the scraper 34 will scrape the silt and debris on the inner wall of the centrifugal drum 32. The silt and debris will fall onto the collecting bucket 33 and be discharged and collected outwardly through the conveying pipe 35. After the end, drive the second pump 26 to make the connecting pipe 25 extract the water inside the centrifugal drum 32, and convey the water to the water storage tank 13 for collection through the collecting pipe 27 on the other side.
