The connector 104 extracts the accumulated water at the bottom of the pit, and the solid matter in the accumulated water is intercepted by the filter screen 107. At this time, the motor 203 can be started to drive the reciprocating screw 204 to rotate, and the reciprocating screw 204 drives the connecting shaft 210 to slide on the inner wall of the support frame 201, and then the connecting shaft 210 drives the slider 206 to slide on the inner wall of the slide groove 205, and the lifting block 215 and its connector 104 are driven by the traction rope 209 to change their bottom position at the pit base.
