[0002] With the continuous innovation of industrial technology, the development of various industries has been driven, and new factories have continued to emerge. However, with the production process of the factory, a large amount of sewage will be generated. At the same time, sewage will also be generated in our lives. As the concept of protecting the environment has been deeply rooted in people's hearts, most of it is now discharged into the sewage pipe, converged through the pipe, and then transported to the centralized sewage treatment place. The sewage is collected and transported through the sewage pipe to avoid the sewage being directly discharged into the river and affecting the natural environment;

[0003] In the existing sewage treatment process, the sewage needs to be discharged into the sewage pipe, and the sewage is collected and transported by the sewage pipe, which improves the sewage transportation efficiency. However, during the long-term use of some existing sewage pipes, dirt will remain on the inner wall of the pipe. After the dirt accumulates for a long time, it may affect the transportation efficiency of the pipe.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The sewage treatment pipe cleaning device, when the shell is installed, first keep the rotating block flush with the appropriate pipe opening of the sewage pipe, and then rotate the second threaded rod. The second threaded rod moves toward the front side of the shell along the thread groove opened by the fixing ring, driving the sliding ring to move synchronously. The sliding ring drives the second protrusion to move synchronously and slide into the fourth cavity. During the sliding process of the second protrusion, the second rotating rod is pushed to tilt at an angle. Since the diameter of the second rotating rod remains unchanged, the end of the second rotating rod close to the scraping block drives the second connecting rod to move outward, and the second connecting rod pushes the scraping block to slide out of the rotating block. When it moves to the appropriate position, The side of the scraper block away from the rotating block contacts the inner wall of the sewage pipe. At this time, the second threaded rod stops rotating to fix the position of the scraper block. Then the motor is turned on, and the output end of the motor drives the first rotating rod to rotate. The convex block on the outer surface of the first rotating rod limits the push rod, so that the push rod can slide toward the outside of the shell while rotating synchronously with the first rotating rod. The rotation of the push rod drives the rotating block to rotate, so that the scraper block performs a circular motion along the inner wall surface of the sewage pipe. In the above manner, the length of the scraper extending out of the rotating block can be adjusted to achieve the cleaning of sewage pipes of different sizes as much as possible, thereby improving the diversity and practicality of the device.

[0015] (2) The sewage treatment pipe cleaning device, when the scraper block cleans the sewage pipe at its initial position, turns on the second motor and opens the water tank at the same time, the second motor drives the threaded rod to rotate, and the threaded rod rotates so that the displacement block connected to the outer surface by the thread moves forward, and during the displacement block moving forward, the second ring is driven to move synchronously through the connecting rod, and the second ring pushes the push rod to slide out of the cleaning equipment body, so that the scraper block can clean the inside of the sewage pipe while keeping rotating, and during the rotation of the push rod, the cleaning agent in the water tank moves downward along the hose into the passage opened in the water inlet pipe due to gravity. In the groove, when the arc groove on the outer surface of the push rod rotates to a suitable position, the arc groove is connected to the water inlet pipe, and the cleaning agent flows through the arc groove into the fourth cavity. Due to the rotation of the push rod, the rotating block is driven to rotate synchronously. Under the action of centrifugal force, the cleaning agent enters the second cavity inside the scraper block through the water delivery groove opened by the second connecting rod, and is sprayed to the outside of the scraper block through the water spray port. Since the scraper block is provided with an inclined surface, when the scraper rotates along the inner wall of the sewage pipe, the cleaning agent is first sprayed on the inner wall, and then the scraper block contacts the inner wall of the sewage pipe. Through the above method, the working efficiency of the device is improved as much as possible, and the quality of the cleaning process is guaranteed as much as possible.

[0036] Working principle: After the shell 1 is installed, the rotating block 6 is first kept flush with the appropriate pipe opening of the sewage pipe, and then the second threaded rod 24 is rotated. The second threaded rod 24 moves toward the front side of the shell 1 along the thread groove opened by the fixing ring 21, driving the sliding ring 25 to move synchronously. The sliding ring 25 drives the second protrusion 20 to move synchronously and slide into the fourth cavity 30. During the sliding process of the second protrusion 20, the second rotating rod 31 is pushed to form an angle tilt. Since the diameter of the second rotating rod 31 remains unchanged, the end of the second rotating rod 31 close to the scraping block 5 drives the second connecting rod 27 to move outward, and the second connecting rod 2 7 pushes the scraper block 5 to slide outward from the rotating block 6. When it moves to a suitable position, the side of the scraper block 5 away from the rotating block 6 contacts the inner wall of the sewage pipe. At this time, the second threaded rod 24 stops rotating, so that the position of the scraper block 5 is fixed, and then the motor 12 is turned on. The output end of the motor 12 drives the first rotating rod 13 to rotate. The convex block 11 on the outer surface of the first rotating rod 13 limits the push rod 9, so that the push rod 9 can rotate synchronously with the first rotating rod 13 and slide toward the outside of the shell 1. The rotation of the push rod 9 drives the rotating block 6 to rotate, so that the scraper block 5 performs a circular motion along the inner wall surface of the sewage pipe. When the scraper block 5 contacts the sewage pipe, the first rotating rod 13 is rotated. After the initial position of the pipeline is cleaned, the second motor 14 is turned on and the water tank 2 is opened at the same time. The second motor 14 drives the threaded rod 17 to rotate. The threaded rod 17 rotates and the displacement block 6 connected to the outer surface threadedly moves forward. During the forward movement of the displacement block 6, the second ring 10 is driven to move synchronously through the connecting rod 15. The second ring 10 pushes the push rod 9 to slide out of the cleaning equipment body 1, so that the scraper block 5 keeps rotating while the inside of the sewage pipe can be cleaned. During the rotation of the push rod 9, the cleaning agent inside the water tank 2 enters the water inlet pipe downward along the hose 3 due to gravity. In the through groove opened by 22, when the arc groove 23 on the outer surface of the push rod 9 rotates to a suitable position, the arc groove 23 is connected with the water inlet pipe 22, and the cleaning agent flows into the fourth cavity 30 through the arc groove 23. Since the push rod 9 rotates to drive the rotating block 6 to rotate synchronously, under the action of centrifugal force, the cleaning agent enters the second cavity 26 inside the scraper block 5 through the water delivery groove 28 opened by the second connecting rod 27, and is sprayed to the outside of the scraper block 5 through the water spray port 19. Since the scraper block 5 is provided with an inclined surface, when the scraper 5 rotates along the inner wall of the sewage pipe, the cleaning agent is first sprayed on the inner wall, and then the scraper block 5 contacts the inner wall of the sewage pipe.

[0037] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
