[0030] Working principle:

[0031] When in use, the water pump of the suction pipe 2 located in the blocking box 3 is started to suck the liquid in the lifting tank body 1, and the liquid enters the blocking box 3 through the filter screen 32 and is sucked by the suction pipe 2;

[0032] The driving motor 6 is started, and the driving motor 6 drives the driving gear 34 through the upper end of the transmission mechanism 5. The driving gear 34 rotates, and the driving gear 34 drives the connecting frame 35 to deflect.

[0033] The outer end of the scraper 312 scrapes off the impurities on the surface of the filter screen 32, and the impurities fall into the collection box 31 under the pressure of the scraper 312. The driving motor 6 drives the capture rod 4 to rotate through the transmission mechanism 5. The capture rod 4 continuously drives the impurities entering the collection box 31 to prevent the impurities from floating out.
