[0044] When a rectangular sedimentation tank is cleaned, the two sides of the bottom of the limiting mechanism 58 are adjusted to abut against the limiting holes on the two sides of the top of the connecting rod 54 to limit and fix the position of the rotating rod 52, then the scraper 56 is driven by the telescopic mechanism 55 to move to the two sides of the sedimentation tank, the connecting block 51 is continuously driven by the lead screw two 24 to move downwards to the sedimentation tank, so that the bottom of the resisting mechanism 53 and the bottom of the scraper 56 abut against the bottom of the sedimentation tank, and the two sides of the scraper 56 abut against the side surface of the sedimentation tank through the telescopic mechanism 55, then the lifting shell 21 is reciprocated in the bottom shell 11 by the lead screw one 12, and the scraper 56 can clean and scrape the sludge accumulated in the sedimentation tank;

[0045] When the circular sedimentation tank is cleaned, the limiting mechanism 58 is first removed from the limiting and fixing of the rotating rod 52, and then the driving part three 59 is opened. The output end of the driving part three 59 drives the gear one 511 to rotate on the connecting block 51. The gear one 511 drives the gear two 512 to mesh and rotate, so that the gear two 512 drives the rotating rod 52 to rotate inside the connecting block 51.

[0047] When the positions of the connecting rod 54 and the rotating rod 52 are fixed, the limiting frame 581 is pulled to move downward through the limiting rod 583, and then the magnet 582 is inserted into the limiting hole on both sides of the top of the connecting rod 54, so as to complete the position fixing of the connecting rod 54 and the rotating rod 52, ensure the position stability of the connecting rod 54 and the rotating rod 52 when cleaning the rectangular sedimentation tank, and avoid affecting the mud scraping effect due to shaking.

[0048] When the limiting of the connecting rod 54 and the rotating rod 52 needs to be removed, the limiting frame 581 is also pulled to drive the magnet 582 to be separated from the limiting hole on both sides of the top of the connecting rod 54.
