The air bag chamber 402 is externally provided with a release port 404 for releasing the internal air bag. A plurality of groups of inflation tubes 403 are connected to the air pump 401 at one end away from the air bag chamber 402. The air bag chamber 402 is hollow and stores the air bag. When the air pump 401 inflates the air bag through the inflation tube 403, the air bag expands in the chamber and pops out of the release port 404, quickly adheres to the pipe wall, and then deflates and shrinks. This process generates strong pulse vibration. A plurality of groups of air bag chambers 402 are distributed in a ring shape and work together to apply pulse force to the pipe wall in all directions. A plurality of groups of air bag installation grooves 101 are annularly provided on the outside of the dredging shell 1.

The plurality of groups of air bag installation grooves 101 are annularly provided on the outside of the dredging shell 1, providing precise installation positions for the air bag chamber 402. When installing, the air bag chamber 402 is aligned with the installation groove and fixed, which can ensure that the position of the air bag in the pipe is uniform, achieving the effect of dredging the pipe in all directions. The pulley installation groove 102 is annularly installed on the outside of the dredging shell 1 and is used to install the pulley. When the dredging device moves in the sewage pipe, the pulley contacts and rolls on the inner wall of the pipe, converting sliding friction into rolling friction, greatly reducing the frictional resistance between the dredging device and the pipe.

[0023] Please refer to Figs. 1-3 In this embodiment, a plurality of groups of rotating shafts 103 are linearly installed in the pulley installation groove 102. The rotating shaft 103 is externally provided with a rotating wheel 104. The rotating shaft 103 in the pulley installation groove 102 cooperates with the rotating wheel 104 to convert the sliding friction between the dredging device and the inner wall of the pipe into rolling friction. When the dredging device moves in the sewage pipe, the rotating wheel 104 rotates flexibly on the rotating shaft 103, significantly reducing the friction between the device and the pipe wall.

The flushing box 3 is fixedly installed at one end with a dirt breaking head 301. The flushing box 3 is connected and installed with a water inlet pipe 303 at one end away from the dirt breaking head 301. The high-pressure water pump in the flushing box 3 can pressurize water to a high pressure. These high-pressure water is injected into the inner wall of the sewage pipe through the plurality of groups of water injection pipes 302 connected and installed on the outside in a ring shape, forming a high-speed water flow. The high-speed water flow has strong impact force, which can effectively wash away the sludge, impurities and other dirt attached to the pipe wall. The water inlet pipe 303 connected and installed at one end away from the dirt breaking head 301 of the flushing box 3 can be connected to an external water source to provide sufficient water for the flushing box 3.

[0024] Please refer to Figs. 2-3In the embodiment, a driving motor is installed inside the cleaning turntable 2, a rotating ring 201 is sleeved outside the cleaning turntable 2, a sprocket wheel is installed between the cleaning turntable 2 and the rotating ring 201, the output end of the driving motor is connected with the rotating ring 201 through the sprocket wheel, the driving motor inside the cleaning turntable 2 is connected with the rotating ring 201 through the sprocket wheel, the transmission ratio of the sprocket wheel transmission can be accurate, the sprocket wheel is installed between the cleaning turntable 2 and the rotating ring 201, and stable connection is provided for the two. In the rotating process of the rotating ring 201, the sprocket wheel can bear large radial force and axial force, the connection between the rotating ring 201 and the cleaning turntable 2 is firm, the connection between the rotating ring 201 and the cleaning turntable 2 will not be loose due to complex working conditions in the sewage pipeline, such as water flow impact, uneven inner wall of the pipeline and other factors, the smooth progress of the cleaning operation is ensured, a plurality of groups of obliquely arranged scraping plates 202 are annularly installed outside the rotating ring 201, a plurality of groups of cleaning grooves 203 are annularly and penetratively arranged outside the rotating ring 201, and the plurality of groups of obliquely arranged scraping plates 202 are annularly installed outside the rotating ring 201. The oblique design can significantly improve the scraping efficiency. When the obliquely arranged scraping plates 202 contact the inner wall of the pipeline, a component force along the axial direction of the pipeline is generated. In the rotating process of the rotating ring 201, the component force can push the scraped sludge, impurities and the like to the downstream of the pipeline, so that the scraped dirt is prevented from re-attaching to the pipeline wall.

[0025] In the process of working, the operator will put the dredging device at the sewage pipe, and the operator will put the dredging device at the sewage pipe. With the help of the pulley installation groove 102, the rotating shaft 103 is sleeved with the rotating wheel 104, and the rotating wheel 104 is pushed into the pipe. The rotating wheel 104 is in contact with the inner wall of the pipe, and the rotating wheel 104 is in contact with the inner wall of the pipe. The frictional resistance between the device and the pipe is greatly reduced, the pushing process is smooth, and the device can flexibly adapt to the bends and ups and downs of the pipe. The driving motor in the cleaning turntable 2 is started, the chain wheel is driven to rotate at high speed, the inclined scraping plate 202 distributed on the outer ring of the rotating ring 201 starts to work, and the inclined scraping plate 202 is designed to scrape the sludge on the inner wall of the pipe. When rotating, not only can the sludge on the inner wall of the pipe be scraped off, but also the scraped dirt can be pushed along the axial direction of the pipe to avoid the reattachment of the dirt. At the same time, the multiple cleaning grooves 203 on the rotating ring 201 can make the scraped dirt fall off in time to prevent the dirt from accumulating on the surface of the rotating ring 201 and ensure the continuous and efficient work of the scraping plate 202. While the cleaning turntable 2 is working, the flushing box 3 is started, the water inlet pipe 303 is connected to the external water source to continuously supply water to the flushing box 3, and the high-pressure water pump in the flushing box 3 pressurizes the water. The high-pressure water is sprayed at high speed to the inner wall of the pipe through the external annular multiple water spray pipes 302, further removing the residual dirt. The dirt breaking head 301 at one end of the flushing box 3 can first break the stubborn dirt to assist the high-pressure water to better play the flushing effect, realize the comprehensive and efficient cleaning of the inner wall of the pipe, and the air bag dredging assembly in the dredging shell 1 starts to work. The air pump 401 fills the air bags in the multiple annularly distributed air bag cabins 402 through the air pipe 403, and the air bags are inflated in the air bag cabins 402. After inflation, the air bags are ejected from the release port 404 and quickly adhere to the pipe wall. Subsequently, the air bags deflate and shrink, and such inflation and deflation are repeated to generate a strong pulse force to shake off the sludge and impurities on the pipe wall that are difficult to be scraped and washed off. Multiple air bags work together to act on the pipe wall in all directions to ensure that there is no dead angle for cleaning. In the whole working process, the device continuously pushes into the deep part of the pipe by means of the rolling of the rotating wheel 104, the cleaning turntable 2, the flushing box 3 and the air bag dredging assembly continuously work, and the inner wall of the pipe is continuously scraped, washed and vibrated to clean the dirt in the sewage pipe and ensure the smoothness of the sewage pipe.

[0026] Through the above steps, when the dredging device starts, the cleaning turntable 2 starts to work, which is located at one end of the dredging shell 1, driven by a motor and other driving devices, using the scraper, brush and other components on the turntable to scrape the inner wall of the sewage pipeline, and the sludge and other dirt attached to the pipeline wall are stripped off. The flushing box 3 connected to the center of the cleaning turntable 2 at one end starts to work after the cleaning turntable 2 performs preliminary scraping on the pipeline wall. The flushing box 3 stores clean water inside. Through the internal pressure device or external water pump, the water is pressurized and sprayed from the flushing box 3 to the inner wall of the sewage pipeline, further cleaning the residual dirt and scraped sludge. The multiple groups of air bag cabins 402 arranged in the ring inside the dredging shell 1 are started during or after the work of the cleaning turntable 2 and the flushing box 3. The gas is filled into the air bag cabin 402 through the inflation pipe 403. When the gas pressure in the air bag cabin 402 reaches a certain degree, the air bag expands, extruding the surrounding space and contacting the pipeline wall. Then, the air is released through the control of the inflation pipe 403, and the air bag contracts. Thus, the inflation and deflation are repeated, generating periodic pulse force, which shakes off the sludge and impurities on the pipeline wall that are difficult to be removed by the cleaning turntable 2 and the flushing box 3, so that they can be discharged from the pipeline with the water flow or subsequent cleaning operation.
