Working principle: After the sewage pipe is connected to the drain flange 16 on the side of the drain port 15, the operator puts the pump into the pool that needs to be drained.

At this time, the driving motor 18 starts, and the output end of the driving motor 18 drives the rotating liquid pipe 20 to rotate, thereby driving a plurality of booster impellers 21 arranged on the rotating liquid pipe 20 to rotate, and the booster impeller 21 rotates to generate a pressure difference, and then the Sewage is pumped upwards through the water inlet 12 at the bottom of the pump body 10. Since the filter screen 13 is rotated at the center of the water inlet 12, the filter screen 13 can block most of the sludge and dirt from the outside and enter the pump. The water inside the body 10 will be discharged outwards through the drain port 15 on one side.

The second rotating ball 34 in the water outlet 15 will be driven to rotate in the process of draining out from the water outlet 15. On the one hand, the drainage speed of the water outlet 15 can be accelerated during the rotation of the second rotating ball 34. The second fan blade 50 on the second rotating ball 34 will drive the water flowing through there into the second liquid inlet hole 35, and then through the intercommunicating pipe liquid inlet hole 36 communicating with it, a part of the water flow will be introduced into the In the communication pipeline 17, the third valve 38 in the communication pipeline 17 will open at this time, so that the water flow can enter the first hydraulic chamber 19 below through the communication pipeline 17, and the first hydraulic chamber 19 receives pressure at this time , it will push the sliding plate 32 slidably arranged in the first hydraulic chamber 19 to move outward, thereby pushing the brush plate 14 arranged on one side of the sliding plate 32 to move outward, thereby pushing the bristles 33 arranged on the brush plate 14 to gradually move Close to the center of the filter screen plate 13, at this time, because the filter screen plate 13 is in a rotating state, the bristles 33 can contact the bottom of the filter screen plate 13, and at this time, the sludge and other dirt at the bottom of the filter screen plate 13 can be brushed Except, in this relationship, the rotational speed of the rotating liquid pipe 20 affects the rotating speed of the filter screen plate 13, which also affects the rotating speed of the supercharged impeller 21, and the rotating speed of the supercharged impeller 21 affects the drainage speed of the water outlet 15, and the water discharge of the water outlet 15 The speed affects the pressure of the water supply of the intercommunicating pipeline 17, which will affect the speed and length of the brush plate 14. Since the bottom of the slide plate 32 is connected with the first spring 31, the slide plate 32 will be pushed out when the pressure is insufficient. Pull it back, so that the bristles 33 move back and forth, so as to better scrub the bottom of the filter screen plate 13 .

During the rotation of the booster impeller 21, since the booster impeller 21 is provided with a plurality of communication holes 37, the water sucked up will also diffuse to the top of the pump body 10, because the first rotating ball 22 is arranged on the rotating liquid Because of the tube 20, the first rotating ball 22 will also rotate accordingly, thereby driving the first fan blade 49 arranged on the first rotating ball 22 to rotate, thereby sucking in water and then passing the water through the first liquid inlet hole 23 Introduce it into the liquid pipe inlet hole 24 that communicates with it, so as to discharge a part of the water into the communication pipe 25. At this time, the first valve 26 set in the communication pipe 25 will open, so that the water in the communication pipe 25 Water is poured into the cleaning chamber 27 through the liquid pipe drain hole 28 provided at the bottom.

After the cleaning chamber 27 is filled with water, the water will first flow into the position between the fixed plate 39 and the movable slide plate 41 through the fixed plate through hole 40 in the middle of the fixed plate 39, and then pass through the movable slide plate provided in the middle of the fixed plate 41. The hole 42 flows to the bottom of the sleeve 46, thereby pushing the sliding rod 47 in the sleeve 46 to move outward, thereby pushing the cleaning block 48 on one side of the sliding rod 47 to move outward, so that the cleaning block 48 is in contact with the inner wall of the pump body 10 , so as to brush the inner wall surface of the pump body 10. When the slide bar 47 moves to the limit length, it will push the moving slide plate 41 at the bottom to slide outward, thereby extending the cleaning range of the cleaning block 48. Since the cleaning chamber 27 is arranged on the rotating liquid pipe 20, the cleaning chamber 27 will also rotate accordingly. During the rotation, the cleaning block 48 will effectively remove the sundries on the wall of the pump body 10 to prevent the sundries from flowing to the booster impeller. 21 or 15 outlets, affecting the operation of the equipment. The sludge washed off by the cleaning block 48 will be sprayed out through the drain hole 29 on one side of the pump body 10 .

The above description is only an embodiment of the present invention, and does not limit the scope of patent protection of the present invention. Any equivalent structure or equivalent process transformation made by using the description of the present invention and the contents of the accompanying drawings, or directly or indirectly used in other related All technical fields are equally included in the scope of patent protection of the present invention.
