[0035] Compared with the prior art, the present application is provided with an outer shell 1 that can move inside the pipe, and the outer shell 1 is moved by supporting legs 2 installed on its outer side. When the pipe needs to be cleaned, multiple supporting legs 2 can be extended at the same time until they are supported on the inner wall of the pipe, and then the outer shell 1 and the structure installed thereon are moved into the inside of the pipe. After reaching the specified position, the structure at its output end can be driven to rotate by the second motor 6, thereby effectively cleaning the inner wall of the pipe. The cleaning end of the cleaning device uses a scraper block 13 to resist and squeeze the inner wall of the pipe, so that the cleaned dirt and impurities can be cleaned and taken out during the subsequent outward movement of the scraper block 13, thereby ensuring the cleaning effect. At the same time, water is supplied to the water inlet pipe 16 by an external water supply device, so that water passes through the cleaning component 9 and flows to the end At the head 11, the water will then form an impact pressure inside the extension support assembly 12, causing the extension support assembly 12 to stretch, and then the scraper block 13 at the end will be deformed when it is squeezed against the inner wall of the pipe, so that a sealing state is formed between it and the inner wall of the pipe, and then the second motor 6 and the cleaning assembly 9 arranged at its end are driven by the rotation of the first motor 3 to move toward the extension support assembly 12, and the end of the cleaning assembly 9 will expand radially when contacting the extension support assembly 12 until the cleaning component contacts the inner wall of the pipe, and then the external driving structure pulls the outer shell 1 and the whole thereon outward, and the cleaning assembly 9 is rotated to clean the inside of the pipe, and the scraper block 13 can be used to bring out the cleaned dirt and impurities, thereby ensuring the quality and effect of cleaning.

At the same time, the water poured into the cleaning component 9 can also enter the extension support component 12, thereby ensuring that the extension support component 12 can be extended and supported to fit the inner wall of the pipe under the action of the water pressure of the water supply during the entire cleaning process. On the one hand, it can ensure the stability of the entire cleaning device when working inside the pipe, and on the other hand, it also ensures that the extension support component 12 can collect dirt and impurities and bring them out of the pipe while the device is scraping and cleaning, thereby further ensuring the cleaning effect.

[0050] Working principle: all the extension support components 12 are compressed so that the scraping blocks 13 are arranged in an interlaced manner, and then the device is placed in the pipeline, and the support legs 2 are started to extend so that the roller support at the end contacts the inner wall of the pipeline, and it is pushed into the pipeline by an external pushing mechanism, and then the external water supply device supplies water to the water collecting tank 15 through the water inlet pipe 16, and the water passes through the water collecting tank 15 through the connecting rod 8 into the bottom block 91, and finally enters the central water pipe 96. The water inside the central water pipe 96 will continue to flow into the central seat 101, and finally sprayed out from the cleaning head 103. The sprayed water can subsequently clean the inner wall of the pipeline, and the remaining water will continue to flow through the end head 11 into the corrugated hose 122, causing the corrugated hose 122 to expand and grow, and then push the inner rod 123 out and move. During the movement, the scraping block 13 gradually approaches the inner wall of the pipeline until it is squeezed and fits the inner wall of the pipeline. The scraping block 13 will deform and fit tightly to the pipeline during this process. The inner wall of the pipe is compressed by the second spring 124 during the deformation process, and then the first motor 3 is started. The first motor 3 drives the driving gear 4 to rotate, and then drives the track bar 7 to move, so that the second motor 6 drives the cleaning component 9 to move as a whole toward the extension support component 12, and the short pin at the end of the scraper and cleaning knife 97 will hit the long groove on the inner rod 123, and the roller thereon will roll therein.

At this time, the second motor 6 is started, and the second motor 6 drives the cleaning component 9, the cleaning component 10, the extension support component 12 and the scraper block 13 to rotate as a whole through the connecting rod 8. The scraper and cleaning knife 97 rotates to remove and clean the dirt and impurities on the inner wall of the pipe, and the cleaning head 103 flushes the inner wall of the pipe, and the scraper block 13 moves to the outside of the pipe while rotating through the traction device connected to the outside of the outer shell 1, scrapes impurities and flushing water, and realizes cleaning of the pipe.
