Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, and in particular to a pipeline cleaning device for municipal water supply and drainage. Background Technology

[0002] Municipal water supply and drainage systems are a very important part of urban infrastructure, undertaking the key functions of domestic water supply, rainwater discharge, sewage collection and transportation. At the same time, with the rapid development of today's society, the scale of cities is gradually expanding and the service life is increasing, so the cleaning of pipes is particularly important to avoid blockages that cause urban drainage difficulties.

[0003] Currently, most pipe cleaning devices use mechanical scraping and robotic cleaning technologies. Some use rotating screws to clean harder blockages, while others use robots to drive scrapers to clean sludge and dirt from the inner walls of pipes. With the rapid development of the times, the general trend is towards mechanization, which reduces labor costs and improves efficiency and safety.

[0004] In existing technologies, mechanical scraping can easily damage the inner wall, while the scraper head of the robotic device is difficult to fit the inner wall and is relatively simple. Relying solely on the scraper head is also insufficient to clean a lot of dirt, and over time, the pipes are difficult to clean thoroughly. Therefore, a pipe cleaning device for municipal water supply and drainage is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a municipal water supply and drainage pipe cleaning device, which aims to improve the problem that the scraper head is difficult to adhere to the inner wall in the existing technology, and is relatively simple, making it difficult to clean the pipes by relying solely on the scraper head.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: It includes a pipe, an outer shell inside the pipe, a second motor fixedly connected to the inner wall of the outer shell, a disc fixedly connected to the output end of the second motor, multiple buffer blocks fixedly connected to the inner wall of the disc, a spring sleeved on the outer wall of the buffer blocks, a support block fixedly connected to the end of the spring away from the disc, multiple scrapers fixedly connected to the top of the support block, a high-pressure nozzle fixedly connected to the center of the disc, and a base plate fixedly connected to the outer wall of the pipe.

[0031] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 3An embodiment of this utility model includes a pipe 7, inside which is a shell 18. A motor 16 is fixedly connected to the inner wall of the shell 18, which has a protective function. A disc 13 is fixedly connected to the output end of the motor 16. Multiple buffer blocks 15 are fixedly connected to the inner wall of the disc 13. A spring 14 is sleeved on the outer wall of the buffer block 15. A support block 9 is fixedly connected to the end of the spring 14 away from the disc 13. Multiple scrapers 8 are fixedly connected to the top of the support block 9. A high-pressure nozzle 12 is fixedly connected to the middle of the disc 13. The motor 16 drives the disc 13 to start rotating. The spring on the disc 13 is elastic, which can make the scrapers 8 on the support block 9 fit more closely to the inner wall of the pipe 7, resulting in a cleaner cleaning. A base plate 1 is fixedly connected to the outer wall of the pipe 7.

[0033] Reference Figures 1-3 A water pump 2 is fixedly connected to the top of the base plate 1, and a water tank 3 is also fixedly connected to the top of the base plate 1. A water pump pipe 4 is fixedly connected to the input end of the water pump 2, and the end of the water pump pipe 4 away from the water pump 2 is fixedly connected to the outer wall of the water tank 3. A water delivery pipe 11 is fixedly connected to the output end of the water pump 2. Water is drawn from inside the water tank 3 through the water pump pipe 4 at the input end of the water pump 2. A bracket 6 is fixedly connected to the top of the base plate 1, and a motor 10 is fixedly connected to the outer wall of the bracket 6. A roller 5 is fixedly connected to the output end of the motor 10. The water delivery pipe 11 is fitted onto the outer wall of the roller 5, and the end of the water delivery pipe 11 away from the water pump 2 is fixedly connected to the bottom of the high-pressure nozzle 12. After the water is drawn out, it is then transported to the high-pressure nozzle 12 by the water delivery pipe 11 at the output end of the water pump 2. The motor 10 drives the roller 5 to rotate, which allows the water delivery pipe 11 to extend and retract, preventing the water pipe from getting tangled. It also helps the robot return to its original position.

[0034] Reference Figure 4 Multiple connecting plates 20 are rotatably connected to the outer wall of the outer shell 18. Wheels 19 are rotatably connected to the two ends of the two connecting plates 20 respectively. A spring 17 is fixedly connected between the two connecting plates 20. The spring 17 makes the connecting plates 20 more flexible and can play a buffering role to reduce wear.

[0035] Reference Figure 3 The buffer block 15 is fixedly connected to the support block 9 at the end away from the disc 13. The buffer block 15 can not only fix the spring 14 to prevent shaking, but also provide some cushioning when the support block 9 is subjected to elastic force.

[0036] Reference Figures 2-4 The water supply pipe 11 runs through the inside of the outer casing 18 and the outer wall of the pipe 7. The water pipe is more aesthetically pleasing and protected when it is inside.

[0037] Reference Figure 1 Multiple wheels 19 are slidably connected to the inner wall of pipe 7, resulting in a wider force-bearing area and a more stable fit during movement.

[0038] Reference Figure 1 Multiple scrapers 8 fit snugly against the inner wall of the pipe 7, allowing for a more thorough cleaning.

[0039] Reference Figure 5 The buffer block 15 is connected to one end of the support block 9 and can slide and extend, so that the support block 9 is buffered when it receives elastic force, preventing damage caused by excessive elasticity.

[0040] Working principle: Water is drawn from the water tank 3 through the water pump 2 input pipe 4, and then the water is sprayed through the high-pressure nozzle 12 to rinse the pipe 7 through the water pump 2 output pipe 11. At the same time as spraying water, the motor 2 16 drives the disc 13 to start rotating, and the scraper 8 of the support block 9 above it also rotates to clean the dirt. The spring 14 has elasticity, which can make the scraper 8 fit more closely to the inner wall of the pipe 7. The wheel 19 on the outer wall of the outer shell 18 and the connecting plate 20 rotate and cooperate with each other, and can slide freely inside the pipe 7. The motor 10 drives the roller 5 to rotate, which can extend and retract the water supply pipe 11, and can also help the robot return to its original position when it stops working.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
