[0026] In the device, the walking structure 1 comprises the frame 11 and the driving wheel 12. The driving wheel 12 is installed at the bottom of the frame 11 and can push the frame 11 to move in the pipe 4 so as to clean the inside of the pipe 4. The cleaning assembly 2 comprises the rotating driving member 21 and the wall scraping member 22. The scraping part of the wall scraping member 22 is arranged at the end far away from the frame 11 and can effectively touch the inner wall of the pipe 4. The rotating driving member 21 is installed on the frame 11 and is connected with the wall scraping member 22. When the wall scraping member 22 contacts the inner wall of the pipe 4, the rotating driving member 21 is used to drive the wall scraping member 22 to rotate around the inner wall of the pipe 4 so as to continuously scrape the sundries on the inner wall of the pipe 4 by the scraping part of the wall scraping member 22, thereby cleaning the inside of the pipe 4.

[0027] In order to ensure that the pipe cleaning tool can stably clean, preferably, in the embodiment, the walking structure 1 further comprises one or more supporting arms, the supporting arms are connected with the frame 11.

[0030] In some possible embodiments, the wall scraping member 22 comprises at least one scraper or scraper plate to facilitate the removal of materials attached to the inner wall of the equipment.

[0031] In the scraping process, it is difficult to ensure that the groove opening for receiving sundries is consistent with the falling point of the scraped sundries, so that the existing flue 4 sundry removal tool still has the problem of sundry accumulation in the flue 4 during use, and the accumulated sundries can further hinder the cleaning work. In order to solve the above problem, the flue 4 sundry removal tool further comprises a material containing assembly 3 in the embodiment, the material containing assembly 3 is connected with the frame body 11, and the material containing assembly 3 can move synchronously when the frame body 11 moves in the flue 4 to take out the sundries falling during the cleaning process. The material containing assembly 3 can take out the falling sundries from the flue 4 in time, and can effectively solve the problem of sundry accumulation encountered by the traditional flue 4 sundry removal tool during use.

[0032] Please refer to Figure 2 In one embodiment, the material containing assembly 3 comprises a material containing hopper 31, and a material collecting cavity is formed on one side of the material containing hopper 31 close to the frame body 11. During the operation of cleaning the flue 4, the sundries falling on the inner wall of the flue 4 will naturally gather on the bottom of the inner wall of the flue 4, and the collecting cavity is used to collect the falling sundries. The bottom of the material containing hopper 31 is designed to be completely consistent with the shape of the bottom surface of the inner wall of the flue 4, so that the bottom of the material containing hopper 31 can closely fit on the bottom surface of the inner wall of the flue 4, and when the material containing hopper 31 moves with the frame body 11, it can effectively take the sundries on the bottom of the inner wall of the flue 4 into the material collecting cavity, thereby realizing the collection of the sundries.

[0033] Further, the edge of the bottom end of the material containing hopper 31 is provided with a scraping tooth 32, which can closely contact with the inner wall of the flue 4 to scrape and remove stubborn dirt and residues attached to the inner wall during movement. In addition, the material containing hopper 31 with the scraping tooth 32 cooperates with the cleaning assembly 2 to comprehensively cover the circumferential surface of the flue 4 for cleaning, which significantly improves the cleaning effect of the inside of the flue 4.

Once the frame body 11 reaches the deepest part of the flue 4, the pneumatic cylinder drives the bottom end of the material pocket 31 to turn downward and abut against the bottom of the inner wall of the flue 4. During movement, the pneumatic cylinder can continuously apply the abutting force, thereby further improving the cleaning effect on the flue 4.

[0035] Working principle: in implementation, the turnover driving member 34 is used to drive the bottom end of the material pocket 31 to turn upward, so that the bottom end of the material pocket 31 is away from the inner wall of the flue 4 after the tool enters the flue 4. Then, the tool is placed in the flue 4. After the frame body 11 reaches the deepest part of the flue 4, the turnover driving member 34 is used to drive the bottom end of the material pocket 31 to turn downward and abut against the bottom of the inner wall of the flue 4. Then, the driving wheel 12 is used to push the frame body 11 to move toward the outlet of the flue 4. During movement, the rotating driving member 21 drives the wall scraping member 22 to rotate and scrape the sundries on the inner wall of the flue 4. The sundries falling from the inner wall of the flue 4 are naturally gathered on the bottom of the inner wall of the flue 4. At the same time, the material pocket 31 scrapes the sundries on the bottom of the inner wall of the flue 4 and carries the sundries into the material collecting cavity as the frame body 11 moves toward the outlet of the flue 4. Finally, the sundries are carried out of the flue 4.

[0036] Working principle: in actual operation, through the action of the turnover driving piece 34, the bottom end of the hopper 31 is turned up, ensuring that the device keeps a certain distance from the inner wall of the smoke pipe 4 after entering the smoke pipe 4. Then, the device is placed into the smoke pipe 4 until the frame body 11 reaches the deepest part of the smoke pipe 4. At this time, the turnover driving piece 34 is used again to turn the bottom end of the hopper 31 down and tightly adhere to the bottom of the inner wall of the smoke pipe 4. Then, the driving wheel 12 starts to work and pushes the frame body 11 to move towards the outlet of the smoke pipe 4. In the moving process, the rotating driving device drives the wall scraping component to rotate, thereby removing the sundries on the inner wall of the smoke pipe 4. The sundries falling off the inner wall of the smoke pipe 4 will naturally gather at the bottom of the inner wall. As the frame body 11 moves towards the outlet of the smoke pipe 4, the hopper 31 moves to scrape the sundries at the bottom of the inner wall and carries the sundries into the material collecting cavity. Finally, the removed sundries are carried out of the smoke pipe 4.
