[0021] The cleaning mechanism 6 includes a fixed ring 601 fixedly connected to the middle of the semi-circular cover 1. A rotating ring 602 is rotatably connected to the front and rear sides of the fixed ring 601. An air extraction ring 603 is fixedly connected to the side of the rotating ring 602 away from the fixed ring 601. A fixed disk 604 is fixedly connected between the inner sides of the rotating ring 602. Spiral capsules 605 are evenly fixedly connected to the front and rear sides of 6.

The cleaning mechanism 6 further includes a fixed shaft 607 fixedly connected to the middle of the spiral capsule 605. Connecting curved rods 608 are rotatably connected to both sides of the fixed shaft 607. The other side of the connecting curved rod 608 is fixedly connected to a sliding block 609. The other side of the sliding block 609 is slidably connected to a sliding groove tube 610. A support spring 615 is fixedly connected to the bottom end of the sliding block 609. The bottom end of the support spring 615 is fixedly connected to the sliding groove tube 610. A stabilizing ring 611 is fixedly connected to the front side of the sliding groove tube 610 through a straight rod. Elastic telescopic sliding rods 612 are evenly fixedly connected to the outer side of the stabilizing ring 611. A telescopic rod 613 is fixedly connected to the side of the sliding groove tube 610 close to the fixed disk 604. The other end of the telescopic rod 613 is fixedly connected to the fixed disk 604. The first intake pipe 201 passes through the semi-circular cover 1 and is communicated with the fixed ring 601. The air extraction pipe 202 passes through the semi-circular cover 1 and is communicated with the air extraction ring 603. The fixed ring 601, the rotating ring 602, the fixed disk 604 and the spiral capsules 605 are communicated. An elastic spiral spring roll is provided inside the spiral capsule 605. Intake ports are evenly provided on the side of the air extraction ring 603 away from the rotating ring 602. The distance between the intake port and the edge of the air extraction ring 603 is greater than the thickness of the limiting semi-circular ring 614. The rotating ring 602 meshes with the driving device 3.

[0022] During use, place the bit pipe 5 inside the lower semi-circular cover 1, making one end of the pipe 5 closely adhere to the limiting semi-circular ring 614. Place the upper semi-circular cover 1 on the top of the lower semi-circular cover 1 to temporarily fix the pipe 5. After the fixation is completed, start the air supply device 2 to fill the fixing ring 601 with air through the first air inlet pipe 201. The air entering the fixing ring 601 enters the spiral bladder 605 through the fixing plate 604, causing the spiral bladder 605 to gradually straighten. Under the action of the fixing shaft 607 and the support spring 615, the spiral bladder 605 can drive the cleaning brush 606 to closely adhere to the top of the pipe 5 and move to clean the inner wall of the pipe 5. At the same time, start the driving device 3. The driving device 3 drives the rotating ring 602 to rotate, so that the rotating ring 602 drives the spiral bladder 605 to rotate to clean the inner wall of the pipe 5. When the fixing plate 604 rotates, it can drive the stabilizing ring 611 to rotate through the telescopic rod 613 and the sliding groove pipe 610, ensuring the stability of the stabilizing ring 611 during rotation. When the air in the spiral bladder 605 is pumped out through the air supply device 2, the spiral bladder 605 is reset by the elastic spiral spring coil arranged inside it. By changing the rotation speed of the driving device 3 and the speed at which the air supply device 2 fills the air into the fixing ring 601 multiple times to change the stretching and rotating speed of the spiral bladder 605 inside the pipe 5, the inner wall of the pipe 5 can be comprehensively cleaned. At the same time, during the reset process of the spiral bladder 605, it cooperates with the rotation of the air extraction ring 603 to drive the rust and dust cleaned from the inner wall of the pipe 5 to the vicinity of the air extraction ring 603. At the same time, under the action of the air supply device 2, the air on the side of the air extraction ring 603 away from the rotating ring 602 is pumped into the rotating ring 602 through the air extraction pipe 202 to collect the rust and dust cleaned from the inner wall of the pipe 5. During snowy weather, start the air supply device 2 to fill the semi-circular air jet ring 401 with air through the second air inlet pipe 203. The air is ejected from the circular air outlet on the semi-circular air jet ring 401 to blow the rotating fan blades 404, causing the rotating fan blades 404 to drive the semi-circular plate 402 to rotate. The rotation of the semi-circular plate 402 drives the cleaning arc plate 403 to rotate to scrape and clean the outside of the pipe 5 to prevent snow from accumulating and freezing at the intersection of the pipe 5 and the semi-circular cover 1, which may affect the separation between the semi-circular cover 1 and the pipe 5. At the same time, while scraping and cleaning the outside of the pipe 5 through the cleaning arc plate 403, due to the arc-shaped setting of the cleaning arc plate 403, part of the accumulated snow on the inner side of the cleaning arc plate 403 can accumulate on the inner side of the middle arc part of the cleaning arc plate 403 after melting, preventing the snow water from entering between the semi-circular cover 1 and the pipe 5 during rotation and causing freezing between the semi-circular cover 1 and the pipe 5.
