[0002] Municipal sewer pipes are an important part of urban infrastructure. They are usually made of materials such as concrete, cast iron, PVC, and HDPE. Their main function is to collect and discharge domestic sewage, rainwater, and industrial wastewater, thereby ensuring urban environmental sanitation and flood control.

[0003] After prolonged use, municipal sewer pipes often become clogged due to the accumulation of grease, food scraps, paper, and other debris. Workers typically use a drain cleaning machine, inserting its flexible shaft into the pipe and using a rotating brush head to clean the municipal sewer pipes regularly.

[0004] Through long-term observation, it has been found that after existing drain cleaning machines clean the pipes, a lot of residue from inside the pipes adheres to their surface. When the flexible shaft is directly wrapped around and stored afterward, the residue not only breeds bacteria and affects hygiene, but also becomes more difficult to clean after it dries. Therefore, a municipal sewer pipe cleaning device is proposed to address the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] like Figure 1-5As shown, a municipal sewer pipe dredging device includes a dredging machine body 1; a flexible shaft 11 is installed at one end of the dredging machine body 1; a bracket 12 is fixedly connected to the outer wall of the dredging machine body 1; two sets of support plates 13 are fixedly connected to the outer wall of the bracket 12; a spring rod 14 is fixedly connected to the inner wall of the support plate 13; a movable block 15 is fixedly connected to the output end of the spring rod 14; scrapers 16 are fixedly connected to the movable block 15 and the inner wall of the bracket 12, and the two sets of scrapers 16 are matched in shape with the flexible shaft 11; two sets of sliding rods 17 are fixedly connected to the inner wall of the movable block 15, and the sliding rods 17 are slidably arranged on the inner wall of the bracket 12; the sliding rods 17 are slidably arranged on the inner wall of the bracket 12; the sliding rods 16 are fixedly connected to the inner wall of the movable block 15; the sliding rods 17 are slidably arranged on the inner wall of the bracket 12; the sliding rods 16 are fixedly connected to the outer wall of the dredging machine body ... A connecting rope 18 is provided at the end of the rod 17, and the connecting rope 18 is through the inner wall of the bracket 12; the end of the connecting rope 18 is fixedly connected to the top plate 19; a clamping plate 110 is fixedly connected to the inner wall of the dredging machine body 1; multiple sets of locking pins 111 matching the shape of the top plate 19 are fixedly connected to the middle of the clamping plate 110; during operation, the operator can move the dredging machine body 1 to the designated work area, unfold the flexible shaft 11 from the middle of the dredging machine body 1 and insert it into the internal area of ​​the pipe, and start the dredging machine body 1 to enable the flexible shaft 11 to work until the subsequent cleaning work of the pipe is completed, and then... When winding and storing the flexible shaft 11, the top plate 19 is moved from a high position to the lower position of the latch 111, and the movable block 15 is pulled down using the connecting rope 18. This allows the movable block 15 to move closer to the bracket 12 under the action of the slide rod 17, until it is completely closed and the two sets of scrapers 16 form a complete circle. At this point, the flexible shaft 11 can be stored, allowing it to slide along the inner walls of the two sets of scrapers 16, and any remaining material on the surface of the flexible shaft 11 is scraped off. When it is necessary to unfold the bracket 12 and the movable block 15 later, the top plate 19 is moved from a low position again. Once the spring rod 14 loses its support, the movable block 15 can be released, allowing its outer wall to contact the support plate 13. This step, combined with the two sets of scrapers 16, improves the cleanliness of the flexible shaft 11 after storage, reducing the risk of bacteria growth and hygiene issues caused by excessive residue on the surface of the flexible shaft 11 after direct storage. It also reduces the problem of dried residue on the surface of the flexible shaft 11 being difficult to clean later. Furthermore, the opening of the two sets of scrapers 16 increases the speed when pulling out the flexible shaft 11 and reduces friction after contact.

[0027] like Figure 1-5As shown, a connector 2 is fixedly connected to the top of the support 12; a frame plate 21 is fixedly connected to the end of the connector 2; two sets of elastic members 22 are fixedly connected to the top of the frame plate 21; a sliding block 23 is fixedly connected to the top of the elastic member 22, and the sliding block 23 is slidably disposed on the inner wall of the frame plate 21; a pressure ball 24 is fixedly connected to the bottom of the sliding block 23; a connecting rod 25 is fixedly connected to the middle of the two sets of sliding blocks 23; a magnetic ball 26 is fixedly connected to the inner wall of one set of pressure balls 24; a magnetic pad 27 is fixedly connected to the top of one set of scrapers 16, and the magnetic pad 27 and the magnetic ball 26 are attracted to each other; during operation, the connector 2 is provided on the top of the support 12 to support the frame plate 21, and when the subsequent movable block 15 is unfolded, the magnetic pad on the top of the scraper 16... 27 can gradually approach the fixed magnetic ball 26 until the two are in a horizontal state. The resulting attraction, combined with the connecting rod 25, drives the two sets of pressure balls 24 to slide downwards, causing the pressure balls 24 to hit the top area of ​​the scraper 16. The resulting vibration can clean the impurities remaining on the inner wall of the scraper 16. The elastic element 22 can then reset the descending pressure balls 24. This step, combined with the impact of the two sets of pressure balls 24 on the top of the scraper 16, can improve the cleanliness of its inner wall and reduce the problem of residue clumping on the inner wall of the scraper 16 over a long period of time, which makes cleaning difficult. At the same time, under the action of the connecting rod 25, the synchronicity of the two sets of pressure balls 24 during descent can be improved, thereby increasing the impact force on the top of the scraper 16.

[0028] like Figure 1-5 As shown, a sliding plate 3 is slidably connected to the inner wall of the card plate 110; a collection groove 31 is provided on the top of the sliding plate 3; a guide plate 32 is fixedly connected to the top of the collection groove 31; a magnetic block 33 is fixedly connected to the inner wall of the card plate 110, and the end of the magnetic block 33 is attracted to the sliding plate 3; during operation, because a sliding plate 3 is provided in the middle of the card plate 110, when the two sets of scrapers 16 scrape off the residue on the surface of the flexible shaft 11, most of the residue can fall to the inner wall of the collection groove 31 under the action of the guide plate 32. When it is necessary to process the impurities on the inner wall after long-term collection, the sliding plate 3 can be pulled outward and completely separated from the magnetic block 33. This step can collect the impurities under the action of the collection groove 31, reducing the pollution to the working environment of the main body of the dredging machine 1. The guide plate 32 can guide the falling impurities and use the magnetic block 33 to reinforce the working position of the sliding plate 3.

[0029] like Figure 1-5As shown, a support rod 4 is fixedly connected to the inner wall of the clamping plate 110; a rotating shaft 41 is rotatably connected to the middle of the support rod 4; an inner groove 42 is opened in the middle of the rotating shaft 41, and the inner groove 42 is in contact with the flexible shaft 11; during operation, the support rod 4 is provided in the middle of the clamping plate 110 to provide positional support for the rotating shaft 41, and when the flexible shaft 11 is unfolded or retracted, it can directly contact the recessed inner groove 42. This step, under the action of the rotating shaft 41, can limit the position of the moving flexible shaft 11 and reduce the wear generated by the flexible shaft 11 during the movement.

[0030] like Figure 1-5 As shown, two sets of reinforcing plates 5 are fixed to the outer wall of the support rod 4; multiple sets of guide plates 51 are fixed to the outer wall of the reinforcing plates 5; during operation, by setting two sets of reinforcing plates 5 on the outer wall of the rotating shaft 41 and providing positional support for the multiple sets of guide plates 51, the rotating shaft 41 can synchronously drive the guide plates 51 to rotate when it rotates, and the unfolded guide plates 51 can center the flexible shaft 11 on the inner wall of the inner groove 42. This step, together with the set guide plates 51, can further reduce the problem of slippage of the flexible shaft 11 when it contacts the rotating shaft 41, and the reinforcing plates 5 can reinforce the working position of the multiple sets of guide plates 51, reducing the problem of deformation and bending.

[0031] like Figure 1-5 As shown, a rotating bead 6 is rotatably connected to the end of the slide rod 17, and the rotating bead 6 is fixedly connected to the connecting rope 18. During operation, by providing the rotating bead 6 at the end of the slide rod 17, the rotating bead 6 can rotate synchronously on the inner wall of the slide rod 17 when the connecting rope 18 is pulled and bent. This step, in conjunction with the rotating bead 6, can reduce the problem of the connecting rope 18 frequently bending at the connection point with the slide rod 17, thus preventing the connection point from breaking.

[0032] like Figure 1-5 As shown, a gasket 7 is fixed to the inner wall of the support plate 13, and the gasket 7 is set on the side close to the movable block 15. During operation, a rotating bead 6 of soft material is set on the inner wall of the support plate 13, and when the movable block 15 contacts and impacts the support plate 13, it can directly contact the gasket 7. This step, in conjunction with the gasket 7, can reduce the wear caused by the impact when the movable block 15 unfolds.

[0033] Working principle: After transferring the main body 1 of the drain cleaning machine to the designated work area, the flexible shaft 11 is unfolded from the middle of the main body 1 and inserted into the internal area of ​​the pipe. Activating the main body 1 allows the flexible shaft 11 to work until the pipe cleaning is complete. When it is necessary to wind and store the flexible shaft 11 again, the top plate 19 is moved from a high position to the lower position of the locking pin 111, and the connecting rope 18 is used to pull down the movable block 15. Under the action of the sliding rod 17, the movable block 15 moves closer to the bracket 12 until it is completely closed, making the two sets of scrapers 16 form a complete circle. At this point, the flexible shaft 11 can be stored. 1. Slide the scraper blades 16 along the inner walls of the two sets of scrapers 16 to remove any residue on the surface of the flexible shaft 11. When the bracket 12 and the movable block 15 need to be unfolded later, move the top plate 19 from a low position to a high position again. This causes the spring rod 14 to lose its support force and the movable block 15 to spring open, allowing the outer wall of the movable block 15 to contact the support plate 13. A connector 2 is provided at the top of the bracket 12 to support the frame plate 21. When the movable block 15 is unfolded later, the magnetic pad 27 at the top of the scraper blades 16 can gradually approach the fixed magnetic ball 26 until they are horizontal. The resulting attraction, combined with the connecting rod 25, drives the two sets of pressure... The ball 24 slides downwards, causing it to strike the top area of ​​the scraper 16. The resulting vibration cleans the impurities remaining on the inner wall of the scraper 16. The elastic element 22 can then reset the descending ball 24. A sliding plate 3 is provided in the middle of the clamping plate 110. When the subsequent two sets of scrapers 16 scrape away residue from the surface of the flexible shaft 11, most of the residue falls onto the inner wall of the collection tank 31 under the action of the guide plate 32. For long-term collection requiring further treatment of impurities on the inner wall, the sliding plate 3 can be pulled outwards to completely detach it from the magnet 33. A support rod 4 is provided in the middle of the clamping plate 110 to provide positional support for the rotating shaft 41. When the flexible shaft 11 is unfolded or retracted, it can directly contact the recessed inner groove 42. Two sets of reinforcing plates 5 are provided on the outer wall of the rotating shaft 41, and multiple sets of guide plates 51 are positioned to support it. When the rotating shaft 41 rotates, it can synchronously drive the guide plates 51 to rotate. The unfolded guide plates 51 can center the flexible shaft 11 on the inner wall of the inner groove 42. A rotating bead 6 is provided at the end of the slide rod 17. When the connecting rope 18 is pulled and bent, the rotating bead 6 can synchronously rotate on the inner wall of the slide rod 17. A rotating bead 6 of soft material is provided on the inner wall of the support plate 13. When the movable block 15 contacts and impacts the support plate 13, it can directly contact the pad 7.
