Working principle: when the connection of the sewage drain pipe and the drain flange 16 on one side of the drain opening 15 is completed, the operator puts the pump into a pool where sewage is required.
At this time, the driving motor 18 is started, the output end of the driving motor 18 drives the rotating liquid pipe 20 to rotate, so as to drive the plurality of pressurizing impellers 21 arranged on the rotating liquid pipe 20 to rotate, the pressurizing impellers 21 rotate to generate pressure difference, then sewage can be pumped upwards through the water inlet 12 at the bottom of the pump body 10, most of sludge and dirt can be blocked outside by the filter screen plate 13 due to the fact that the filter screen plate 13 is rotationally arranged at the center of the circle of the water inlet 12, and water entering the inside of the pump body 10 can be discharged outwards through the water outlet 15 at one side.
In the process of outwards draining the water in the water outlet 15, the second rotating ball 34 in the water outlet 15 is driven to rotate, the drainage speed of the water outlet 15 can be accelerated in the process of rotating the second rotating ball 34, on the one hand, the second fan blades 50 arranged on the second rotating ball 34 can drive the water flowing through the water outlet into the second liquid inlet holes 35, then a part of water flow is introduced into the communicating pipeline 17 through the communicating pipeline liquid inlet holes 36 communicated with the water outlet, at the moment, the third valve 38 in the communicating pipeline 17 can be opened, so that water flow can enter the first hydraulic bin 19 below through the communicating pipeline 17, at the moment, the pressure is recovered in the first hydraulic bin 19, the sliding plate 32 arranged in the first hydraulic bin 19 is pushed to outwards move, and the brush plate 14 arranged on one side of the sliding plate 32 is pushed to outwards move, so that the brush hair 33 arranged on the brush plate 14 is gradually approaches to the center of a filter screen 13, at the moment, the brush hair 33 is contacted with the bottom of the filter screen 13 in a rotating state, at the moment, the brush hair 33 can be contacted with the bottom of the filter screen 13, at the moment, the sludge at the bottom of the filter screen 13 can be pulled out of the filter screen 13, and the water outlet is pulled back and forth, the pressure is influenced by the second hydraulic bin 19, and the pressure is influenced by the pressure is recovered in the first hydraulic bin 19, so that the sliding plate 32 is outwards moved, and the brush plate 14 arranged on one side in the side of the first hydraulic bin 19, so that the sliding plate 32 is gradually, and outwards, so that the brush plate 14 is gradually moves towards the filter plate 13, and at the position, and is arranged.
In the process of rotating the booster impeller 21, because the booster impeller 21 is provided with a plurality of through holes 37, the sucked water also flows to the top of the pump body 10, and because the first rotating ball 22 is arranged on the rotating liquid pipe 20, the first rotating ball 22 also rotates along with the rotating ball, so that the first fan blades 49 arranged on the first rotating ball 22 are driven to rotate, the water is sucked into the liquid pipe liquid inlet holes 24 communicated with the first liquid inlet holes 23, and then, a part of the water is discharged into the communicating pipe 25, at the moment, the first valve 26 arranged in the communicating pipe 25 is opened, and the water in the communicating pipe 25 is infused into the cleaning bin 27 through the liquid pipe liquid outlet holes 28 arranged at the bottom.
After water is poured into the cleaning bin 27, water flows into a position between the fixing plate 39 and the movable slide plate 41 through the fixing plate through hole 40 in the middle of the fixing plate 39, and then flows to the bottom of the sleeve 46 through the movable slide plate through hole 42 in the middle of the movable slide plate 41, so that the slide rod 47 in the sleeve 46 is pushed to move outwards, the cleaning block 48 on one side of the slide rod 47 is pushed to move outwards, the cleaning block 48 is contacted with the inner wall surface of the pump body 10, the inner wall surface of the pump body 10 is cleaned, and after the slide rod 47 moves to the limit length, the movable slide plate 41 at the bottom is pushed to slide outwards, so that the cleaning range of the cleaning block 48 is prolonged. Because the cleaning bin 27 is arranged on the rotating liquid pipe 20, the cleaning bin 27 can rotate along with the rotating liquid pipe, and the cleaning block 48 can effectively remove impurities on the wall surface of the pump body 10 in the rotating process, so that the impurities are prevented from flowing to the supercharging impeller 21 or the water outlet 15, and the operation of equipment is prevented from being influenced. The sludge brushed by the cleaning block 48 is sprayed outwards through the sewage draining hole 29 on one side of the pump body 10.
