A sealing ring 18 is fixed on the front side of the support tube 6 to increase the sealing performance between the impeller 5 and the connecting pipe 4.

[0037] The working principle of the utility model is: when water flows through the drain pipe 2, the impurities in the water flow are filtered through the filter cartridge 7 to prevent the impurities from rushing into the gate valve 3. In case of emergency, the gate valve 3 can be quickly closed to play a protective role;

[0038] When a lot of impurities accumulate inside the filter cartridge 7, the hydraulic rod 9 can be started through the external controller. The hydraulic rod 9 drives the sealing plug 10 to be inserted into the sealing sleeve 11 to close the drain pipe 2. Then the staff manually turns the knob 16. The knob 16 cooperates with the screw 15 to drive the pressure plate 17 not to contact the wheel 5. At the same time, the rotating frame 13 is rotated to make the rotating frame 13 vertically upward. Then the wheel 5 is manually rotated. The wheel 5 drives the support pipe 6 to rotate, disengage from the connecting pipe 4, and take out the filter cartridge 7, which is convenient for the staff to clean the impurities inside the filter cartridge 7.
