[0028] A double-helix submersible sewage pump includes a pump body 1. An inlet base 3 is fixedly connected to the bottom of the pump body 1. A cleaning component 5 is disposed on the outer side of the inlet base 3, and a drive component 6 is disposed at the bottom of the inlet base 3. The cleaning component 5 includes two arc-shaped plates 501 disposed on the outer side of the inlet base 3. Each arc-shaped plate 501 has a connecting hole 503 at its bottom. An installation cavity 504 is formed on the side of each connecting hole 503 that is far apart from each other. A pull rod 505 is disposed inside each installation cavity 504. A connecting plate 506 is fixedly connected to the end of each pull rod 505 that is close to each other. The two connecting plates 506 are further apart from the pull rod 505. Each side is fixedly connected with a snap-fit ​​rod 508. The drive assembly 6 includes a fixed base 601 set at the bottom of the water inlet base 3. The inner cavity of the fixed base 601 is provided with a drive motor 603. The output end of the drive motor 603 is connected to a disc 602 through a rotating shaft. One end of the disc 602 away from the drive motor 603 is fixedly connected with a connecting snap-fit ​​rod 604. The outer wall of the connecting snap-fit ​​rod 604 is rotatably connected with a connecting shaft 605. The bottom of the inner cavity of the fixed base 601 is provided with a movable plate 606. Both ends of the top of the movable plate 606 are fixedly connected with support rods 607. The top of the opposite side of the two support rods 607 is provided with snap-fit ​​holes 608.

[0029] like Figure 2 , Figure 3 As shown, the end of the connecting shaft 605 away from the connecting rod 604 is rotatably connected to the surface of the moving plate 606. The ends of the two pull rods 505, which are away from each other, extend to the outside of the two mounting cavities 504 respectively. The outer walls of the two connecting plates 506 are slidably connected to the inner walls of the two mounting cavities 504 respectively. The top ends of the two support rods 607 penetrate the top of the fixed base 601 and extend to the inside of the two connecting holes 503 respectively. The ends of the two locking rods 508, which are away from the connecting plate 506, extend to the outside of the two mounting cavities 504 respectively and are locked to the two locking holes 608. Springs 507 are sleeved on the outside of the two pull rods 505. One end of the two springs 507 is fixedly connected to the inner wall of the two mounting cavities 504 respectively, and the other end of the two springs 507 is fixedly connected to the surface of the two connecting plates 506 respectively.

[0030] like Figure 1 , Figure 2 As shown, the two ends of the two arc-shaped plates 501 are tightly attached to each other, and the inner sides of the two arc-shaped plates 501 are provided with cleaning brushes 502. One side of the pump body 1 is connected to the water outlet pipe 2, and the side wall of the water inlet base 3 is evenly provided with water inlets 4.

[0031] The working process of this utility model is as follows: During the process of pumping sewage, impurities or algae in the water will adhere to the outside of the filter screen at the inlet 4. The drive motor 603 drives the disc 602 to rotate, and the connecting shaft 605 drives the moving plate 606 and the support rod 607 to move up and down. The arc plate 501 and the cleaning brush 502 move up and down under the action of the support rod 607 to clean the inlet 4 and prevent the inlet 4 from being blocked. By pulling the two pull rods 505 to move to both sides, the two locking rods 508 are moved away from the inside of the locking hole 608, and the two arc plates 501 can be removed from the top of the support rod 607. The two arc plates 501 can be disassembled to facilitate the cleaning of the cleaning brush 502.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
