When the first motor 2 is started, the rotating plate 3 is driven to rotate, so that the rotating plate 3 indirectly drives the second connecting plate 8 to rotate, so that the main drill bit 9 on the left side of the second connecting plate 8 can dredge the blockage. The left side of the rotating plate 3 is fixedly installed with a second motor 4. The left side of the rotating plate 3 is evenly connected with a first connecting column 5. The left end of the first connecting column 5 is fixedly connected to the first connecting plate 6. The left side of the first connecting plate 6 is symmetrically connected to the second connecting column 7. The left end of the second connecting column 7 is fixedly connected to the second connecting plate 8. The circular diameter of the second connecting plate 8 is larger than the first connecting plate 6. The left side of the second connecting plate 8 is fixedly connected to the main drill bit 9. The outer side of the first connecting plate 6 is symmetrically hinged with a first connecting arm 10. The opposite sides of the two first connecting arms 10 are hinged with second connecting arms 11. The connecting plate 6 and the opposite side of the second connecting plate 8 are rotatably connected with a screw rod 12, and the outer side of the screw rod 12 is movably screwed with a sliding member 13. The front and rear ends of the sliding member 13 are hinged to the two second connecting arms 11 away from one end of the two first connecting arms 10. Start the second motor 4, and the second motor 4 drives the screw rod 12 to rotate, so that the sliding member 13 moves left and right, driving the hinged second connecting arm 11 to move, and then driving the mounting plate 24 on the first connecting arm 10 to move, and fit according to the diameter of the pipe wall. The left end of the first connecting arm 10 is fixedly connected to the mounting plate 24, and the left side of the mounting plate 24 is symmetrically connected to the side drill bit 14. Start the third motor 15 to drive the side drill bit 14 to rotate. At the same time, because the first motor 2 drives the rotating plate 3 to rotate, the side drill bit 14 can be cleaned along the pipe wall, and the cleaning effect is better. The third motor 15 is symmetrically installed on the right side of the mounting plate 24. The outer side of the propulsion section 1 is evenly provided with mounting grooves 16, and the inner side of the mounting groove 16 is hinged with a propulsion member 17.
[0023] Among them, the left side of the propulsion section 1 is fixedly connected with a rotating sleeve 18, the first motor 2 is located on the inner side of the rotating sleeve 18, and an annular groove 19 is opened on the right side of the rotating plate 3.

At this time, the fourth motor 21 is started to drive the pulley 22 to rotate, and the device moves in accordance with the pipe wall.
[0024] Working principle: When the device is used, the device is placed in the drainage pipe, and then the first motor 2 is started to drive the rotating plate 3 to rotate, so that the rotating plate 3 indirectly drives the second connecting plate 8 to rotate, so that the main drill bit 9 on the left side of the second connecting plate 8 clears the blockage, and then the second motor 4 is started. The second motor 4 drives the screw rod 12 to rotate, so that the sliding member 13 moves left and right, driving the hinged second connecting arm 11 to move, and then driving the mounting plate 24 on the first connecting arm 10 to move, and fit according to the diameter of the pipe wall, and then start the third motor 15 to drive the side drill bit 14 to rotate. At the same time, because the first motor 2 drives the rotating plate 3 to rotate, the side drill bit 14 can clean along the pipe wall, and the cleaning effect is better. Then, when the device has completely drained the pipe, according to the diameter of the pipe, the propulsion arm 20 compresses the spring 23, so that the propulsion arm 20 tilts, driving the pulley 22 to completely fit with the pipe wall, and then start the fourth motor 21 to drive the pulley 22 to rotate, and fit the pipe wall to drive the device to move.
