A flow guide cover 15 is fixedly connected to the outer wall of one side of the movable plate 7 near the connecting column 12 by screws, and a two-way pump 16 is fixedly connected to the outer wall of one side of the movable platform 1 near the second electric push rod 6 by screws, and a connecting pipe 17 is fixedly connected between the two-way pump 16 and the flow guide cover 15 by screws. A telescopic bellows 18 is fixedly connected to the outer wall of the other side of the movable platform 1 near the two-way pump 16 by screws. The flow guide cover 15 and the telescopic bellows 18 are both connected to the two-way pump 16, and the telescopic bellows 18 are connected to the inlet and outlet pipes 19. The end of the telescopic bellows 18 away from the movable platform 1 is fixedly connected to the inlet and outlet pipes 19, and the cross-sections of the flow guide cover 15 and the inlet and outlet pipes 19 are both L-shaped structures.

[0023] It should be noted that since most of the existing clean room exhaust ducts are cleaned manually with a long pole, and since some exhaust ducts are long, it is not only difficult to clean the depth, but also makes it difficult for the staff to control the long pole for cleaning. This embodiment can realize the section-by-section cleaning of the exhaust duct by the step-by-step movement of the cleaning device in the exhaust duct. Not only can the deep part of the exhaust duct be cleaned, but there is no need for manual cleaning with a long pole, which saves time and effort while ensuring the cleaning effect. The retractable first scraper 9 and the second scraper 11 can be used to scrape the sewage and dirt generated during the exhaust duct cleaning process, thereby ensuring the cleanliness of the inner wall of each exhaust duct after cleaning, and will not interfere with the normal movement of the device inside the exhaust duct.

[0024] Specifically, in this embodiment, this solution mainly includes a moving platform 1, a moving plate 7 and a supporting plate 13. When cleaning the exhaust duct of the clean room, the size of the moving platform 1 is customized according to the size of the exhaust duct so that the walking wheels 3 on the moving platform 1 are in close contact with the inner wall of the exhaust duct. At this time, the moving platform 1 is placed inside the exhaust duct, and cables and wires are used to provide control signals and power to the device. The servo motor 2 is controlled to drive the walking wheels 3 to rotate through the output end on one side thereof. The friction between the walking wheels 3 and the exhaust duct is used to realize the movement of the device in the exhaust duct, and the control device is moved deep into the exhaust duct. Then, the first electric push rod 4 is controlled to drive the extrusion block 5 to move through the output end on one side thereof. The extrusion block 5 is squeezed on the inner wall of the exhaust duct to realize the fixing of the position of the moving platform 1 in the exhaust duct, and the second electric push rod 6 is controlled to drive the moving plate 7 to move through the output end on one side thereof. At the connection of the connecting column 12 The support plate 13 moves synchronously, and the bristles 14 on the support plate 13 brush the exhaust duct, and one of the two-way pumps 16 is used to draw external water (bucket, water pipe, etc.) into the exhaust duct through the inlet and outlet pipes 19, the telescopic bellows 18, the connecting pipe 17 and the air guide cover 15 in sequence. After the exhaust duct cleaning is completed, the movable plate 7 is controlled to reset, and then the third electric push rod 8 and the fourth electric push rod 10 are controlled to drive the first scraper 9 and the second scraper 11 to move through the output ends on one side thereof. The first scraper 9 and the second scraper 11 are docked to form a frame structure and fit the inner wall of the exhaust duct. The frame structure moves synchronously when the movable plate 7 moves, and the frame structure pushes the sewage and dirt in the exhaust duct forward and gathers them, and another two-way pump 16 is used to extract the sewage and dirt in the exhaust duct, and then the movable platform 1 is controlled to move again. The step-by-step movement of the movable platform 1 can realize the cleaning of the exhaust duct section by section.

[0025] In a further preferred embodiment of the present invention, Figure 1 and Figure 3 As shown, there are four servo motors 2 , and the four servo motors 2 are symmetrically arranged inside the moving platform 1 , and the running wheels 3 protrude from the moving platform 1 .

[0026] In this embodiment, four servo motors 2 can be used to control the rotation of four running wheels 3, so that the friction between the running wheels 3 and the exhaust duct can be used to achieve stable movement of the device inside the exhaust duct.

[0027] In a further preferred embodiment of the present invention, Figure 1 and Figure 3 As shown, a receiving groove is provided on one side outer wall of the movable platform 1 near the outer side of the extrusion block 5 .

[0028] In this embodiment, the extrusion block 5 can be accommodated by the accommodation groove, thereby preventing the extrusion block 5 from contacting the inner wall of the exhaust duct and causing movement interference.

[0029] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the cross section of the second scraper 11 is an L-shaped structure.

[0030] In this embodiment, the L-shaped second scraper 11 can be easily fitted on the inner bend of the inner wall of the exhaust duct.
