Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, specifically to a sewage plastic pipe that is easy to clean. Background Technology

[0002] Sewage plastic pipes are pipes used to transport and discharge pollutants such as sewage and wastewater. Commonly used materials include polyvinyl chloride and polyethylene. Compared with traditional metal pipes, plastic pipes are much lighter, which makes the transportation and installation of the pipes more convenient and faster. Sewage conveying pipes are widely used in municipal drainage projects.

[0003] In municipal drainage projects, rainwater carries pollutants such as surface mud and food scraps into sewage pipes, causing blockages. Traditional municipal drainage pipe cleaning often relies on manual labor with simple tools. For long pipes or those with a lot of dirt, this requires a lot of time and manpower, resulting in low cleaning efficiency. Therefore, a sewage plastic pipe that is easy to clean is proposed to solve the problems mentioned above. Utility Model Content

[0004] To solve the above-mentioned technical problems, a sewage discharge plastic pipe that is easy to clean is provided. This technical solution solves the problem of low efficiency in manually cleaning pollutants mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a sewage discharge plastic pipe that is easy to clean, including a connecting pipe, both ends of which are connected to a pipe body, and two flanges are provided at the connection points between the two pipe bodies and the connecting pipe. Threaded holes are opened through the interior of each of the four flanges, and bolts are threaded into the internal threads of the threaded holes. Two symmetrically distributed convex blocks are fixedly connected to the inner wall of the pipe body, and a cleaning component is provided between the two convex blocks.

The outer surface of the cleaning ring has two symmetrically distributed concave grooves. Rotation grooves are formed at the ends of the two convex blocks that are close to each other.

[0009] Preferably, the two concave grooves are correspondingly provided with the two convex blocks, and the two convex blocks are slidably connected to the interior of the two concave grooves respectively.

[0010] Preferably, each of the two rotating grooves is rotatably connected to a rotating shaft, each of the two rotating shafts is fixedly connected to an eccentric wheel on its outer surface, each of the two eccentric wheels is fixedly connected to a fixing block on its outer surface, and each of the two concave grooves has a fixing groove on the side that is close to each other.

[0015] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0016] Reference Figures 1-4The diagram shows an easy-to-clean sewage pipe, including a connecting pipe 2, with both ends of the connecting pipe 2 connected to a pipe body 1. The connecting pipe 2 is relatively short and can be manually cleaned using a soft brush or rinsed with water using a hose. The inner surface of the pipe body 1 is coated with an epoxy resin coating 8, which has a relatively smooth surface, making it difficult for dirt and other impurities to adhere to the inner wall of the pipe body 1, making it easier to clean. Two flanges 3 are provided at the connection between the two pipe bodies 1 and the connecting pipe 2. Sealing gaskets 9 are fixedly connected to the inner side of multiple flanges 3. The sealing gaskets 9 can fill the tiny gaps at the connection of the flanges 3, thereby effectively preventing sewage from leaking from the connection between the pipe body 1 and the connecting pipe 2. Threaded holes 4 are opened through the interior of the four flanges 3, and bolts 5 are threaded into the interior of the threaded holes 4. Two symmetrically distributed convex blocks 6 are fixedly connected to the inner wall of the pipe body 1, and a cleaning component 7 is provided between the two convex blocks 6. Furthermore, the cleaning component 7 includes a cleaning ring 701, which is disposed inside the pipe body 1. Multiple sieve holes 702 are formed through the interior of the cleaning ring 701. The shape of the cleaning ring 701 matches the interior of the pipe body 1. The sieve holes 702 can perform preliminary screening of impurities, intercepting larger impurities and preventing them from directly entering subsequent parts of the pipe. Water can freely pass through the sieve holes 702. Multiple cleaning brushes 703 are fixedly connected to the outer surface of the cleaning ring 701. By moving the multiple cleaning brushes 703 on the outer surface of the cleaning ring 701 within the pipe body 1, dirt on the inner wall can be effectively scraped off, reducing the complexity of manual operation and improving cleaning efficiency. All cleaning brushes 703 are movably connected to the inner wall of the pipe body 1. Two symmetrically distributed concave grooves 704 are formed on the outer surface of the cleaning ring 701. The two concave grooves 704 are correspondingly arranged with two convex blocks 6. The two convex blocks 6 are slidably connected inside the two concave grooves 704, with the ends of the two convex blocks 6 close to each other. Both rotating grooves 705 are provided, and rotating shafts 706 are rotatably connected inside each of the two rotating grooves 705. Eccentric wheels 707 are fixedly connected to the outer surfaces of both rotating shafts 706, and fixing blocks 708 are fixedly connected to the outer surfaces of both eccentric wheels 707. Fixing grooves 709 are provided on the side of each of the two concave grooves 704 that are close to each other. The two fixing blocks 708 are correspondingly arranged with the two fixing grooves 709. One end of each of the two rotating shafts 706 passes through one side of the rotating groove 705 and is fixedly connected to a handle 710. In use, the handle is rotated to open the groove. 710 drives the eccentric wheel 707 to move the fixed block 708 out of the fixed groove 709. The end of the cleaning ring 701 away from the handle 710 is fixedly connected to the pull rod 711. The length of the pull rod 711 matches the length of the pipe body 1. When in use, the cleaning ring 701 is pulled along the pipe body 1 by pulling the pull rod 711 from the end away from the cleaning ring 701. The convex block 6 and the concave groove 704 slide and engage, allowing the cleaning ring 701 to slide on the convex block 6. After cleaning, the pull rod 711 is pushed in the opposite direction to restore the position of the cleaning ring 701.

[0017] The usage process of this utility model is as follows: When cleaning the pipeline, first loosen the bolt 5 to remove the flange 3 and separate the pipeline body 1 from the connecting pipe 2. Rotate the handle 710 to drive the eccentric wheel 707 so that the fixing block 708 moves out of the fixing groove 709. Then, pull the pull rod 711 to pull the cleaning ring 701 from the end away from the cleaning ring 701 to clean along the pipeline body 1. The convex block 6 and the concave groove 704 slide and fit together so that the cleaning ring 701 slides on the convex block 6. At the same time, the cleaning brush 703 on the surface of the cleaning ring 701 scrapes and cleans the inner wall of the pipeline body 1. Impurities are pushed to one end of the pipeline body 1 for treatment. Then, push the pull rod 711 in the opposite direction to restore the position of the cleaning ring 701. Rotate the handle 710 to lock the fixing block 708 into the fixing groove 709 for fixation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
