[0020] The motor 3 drives the threaded rod 4 to rotate, thereby moving the crossbeam 6 on the slide rod 7 and the threaded rod 4. By controlling the motor 3 to rotate alternately forward and reverse, the crossbeam 6 can drive the mounting frame 10 and the scraper 11 to reciprocate at the bottom of the cleaning tank 1 through the connecting arm 9. When the scraper 11 moves away from the drain valve 14, the scraper lifting action component causes the scraper 11 to separate from the bottom of the cleaning tank. When the scraper 11 moves toward the drain valve 14, the scraper lifting action component causes the scraper 11 to contact the bottom of the cleaning tank, thereby cleaning the sediment attached to the bottom wall of the cleaning tank 1 and discharging it at the drain valve 14.

[0021] Furthermore, the scraper lifting action assembly includes a push-pull electromagnet 5 installed at the lower part of the crossbeam 6, and a connecting rod 8 is hingedly connected between the action end of the push-pull electromagnet 5 and the mounting frame 10;

[0022] When the scraper 11 moves in the direction away from the drain valve 14, the push-pull electromagnet 5 is energized and pushes one end of the mounting frame 10 through the connecting rod 8, so that the scraper 11 is separated from the bottom of the cleaning tank. When the scraper 11 moves in the direction close to the drain valve 14, the push-pull electromagnet 5 is de-energized, and the mounting frame 10 makes the scraper 11 contact with the bottom of the cleaning tank under the action of the torsion spring 23.

[0023] Further, a drain valve 14 is provided at the lower part of the cleaning tank 1, and a mud-water separation component is provided at the lower part of the drain valve 14, and the mud-water separation component includes a dehydration barrel 15 and a filter screen 16, and the filter screen 16 is rotatably installed in the dehydration barrel 15, and the outlet section of the drain valve 14 extends into the filter screen 16, and a driving component is provided between the outer wall of the filter screen 16 and the inner wall of the dehydration barrel 15, and the dehydration barrel 15 is connected with a drain pipe 13;

[0026] The function of the coil winding 20 is equivalent to the stator of the brushless motor, and the function of the annular magnet 22 is equivalent to the permanent magnet rotor of the brushless motor. When the coil winding 20 is energized, the filter screen 16 rotates. Under the centrifugal effect, the liquid in the filter screen 16 enters the dehydration barrel 15 and is discharged through the drain pipe 13, and the solid matter remains in the filter screen 16. After the cleaning tank 1 is drained, the sewage gate 17 is opened to discharge the solid matter in the filter screen 16.

[0027] Embodiment: The motor 3 drives the threaded rod 4 to rotate, thereby causing the crossbeam 6 to move on the slide rod 7 and the threaded rod 4. By controlling the motor 3 to rotate alternately forward and reverse, the crossbeam 6 can drive the mounting frame 10 and the scraper 11 to reciprocate at the bottom of the cleaning tank 1 through the connecting arm 9. When the scraper 11 moves away from the drain valve 14, the push-pull electromagnet 5 is energized and pushes one end of the mounting frame 10 through the connecting rod 8 to separate the scraper 11 from the bottom of the cleaning tank. When the scraper 11 moves toward the drain valve 14, the push-pull electromagnet 5 is disconnected. When electricity is supplied, the mounting frame 10 makes the scraper 11 contact with the bottom of the cleaning tank under the action of the torsion spring 23, and then the sediment attached to the bottom wall of the cleaning tank 1 is swept to the drain valve 14 for discharge, and the solid-liquid mixture discharged from the drain valve 14 enters the filter screen 16. When the coil winding 20 is energized, the filter screen 16 rotates. Under the action of centrifugation, the liquid in the filter screen 16 enters the dehydration barrel 15 and is discharged through the drain pipe 13, and the solid matter remains in the filter screen 16. After the cleaning tank 1 is drained, the sewage gate 17 is opened to discharge the solid matter in the filter screen 16.
