[0032] The hemispherical groove 17 cooperates with the spherical ball 18 to make the mounting plate 15 swing at a certain angle, which is convenient for passing through the corner. When the sliding rod 19 moves outward, the spherical ball 18 moves, so that the mounting plate 15 and the positioning wheels 16 are ejected from the receiving groove 13, and the positioning wheels 16 are tightly attached to the pipe wall.

[0033] In the embodiment, the inside of the positioning seat 3 is provided with a driving cavity 21. The side walls of the driving cavity 21 are rotatably provided with a lead screw 22. The lead screw 22 is threadedly connected with a cone 23. The sliding rod 19 penetrates into the driving cavity 21, so that the roller 20 is rollingly connected with the surface of the cone 23. The lead screw 22 penetrates out of the end of the positioning seat 3 and is fixedly connected with a rotating disc 24. The rotating disc 24 is fixedly connected with the spring chain 4.

[0034] Wherein, the spring chain 4 can be manually reversed to drive the rotating disc 24 to rotate, the rotating disc 24 drives the screw rod 22 to rotate, the screw rod 22 drives the cone 23 to move, thereby lifting the slide rod 19 through the roller 20, and at the same time, the spring chain 4 can be connected to the electric drill through the threaded handle 5, the electric drill is rotated forward at high speed (the positioning wheel 16 is retracted), and the cleaning head 1 is rotated through the spring chain 4, the positioning seat 3 and the steering mechanism 2.

[0035] In specific application, the manual cleaning mode: ensure that the components including the cleaning head 1, the steering mechanism 2, the positioning seat 3, the spring chain 4 and the threaded handle 5 are assembled, check whether the motor 6 works normally, and ensure that the cleaning sheet 8 and the cleaning block 9 are intact, when the spring chain 4 is manually rotated, the rotating disc 24 drives the cone 23 to move through the screw rod 22, the cone 23 is lifted when moving, thereby moving the positioning wheel 16 out of the storage slot 13 and abutting against the side wall of the flow channel, which helps to keep the cleaning head 1 in the center position in the flow channel and ensure that the cleaning sheet 8 can uniformly clean the inner wall of the flow channel, the motor 6 in the cleaning head 1 is turned on, the output end of the motor 6 drives the rotating shaft 7 to rotate, thereby driving the cleaning sheet 8 to rotate at high speed, the threaded handle 5 is manually operated, and the cleaning head 1 is pushed into the flow channel through the spring chain 4. During the pushing process, the force should be controlled to avoid scratching the inner wall of the flow channel, the cleaning sheet 8 is rotated by the motor 6 when the cleaning head 1 is pushed, and plastic residues and impurities in the flow channel are effectively removed, when the cleaning head 1 reaches the specified position of the flow channel, the pushing is stopped and the cleaning head 1 is pulled back. During the pulling back process, the positioning wheel 16 is manually operated to be retracted into the storage slot 13. The automatic cleaning mode (processing flow channel blockage): the threaded handle 5 is connected to the output end of the electric drill or other external power source, it is ensured that the connection is firm and reliable, the electric drill is started and rotated forward at high speed. The power of the electric drill is transmitted to the cleaning head 1 through the threaded handle 5, the spring chain 4 and the positioning seat 3, and the cleaning head 1 is rapidly rotated. Under the drive of the electric drill, the cleaning head 1 rotates at high speed and is pushed into the flow channel. The cleaning block 9 is in close contact with the side wall of the flow channel under high-speed rotation, and can strongly remove stubborn residues and blockages in the flow channel. The cleaning head 1 is continuously pushed to pass through the blockage area of the flow channel, and the blockages are gradually removed by the high-speed rotation and friction of the cleaning block 9, so that the flow channel is restored to be unobstructed, and the cleaning head 1 is taken out of the flow channel after the blockages are removed.
