[0026] Working principle: The scraper 21 used to remove impurities such as scale on the inner wall of the pipe is set on the main shaft 1 through the first connecting rod 22, so that the scraper 21 can rotate with the rotation of the main shaft 1, and then the mounting seat 4 at the end of the main shaft 1 is connected to the motor output shaft, the scraper 21 is inserted into the inside of the pipe, and the motor is started to drive the main shaft 1 to rotate. The scraper 21 contacts the inner wall of the pipe and rotates itself to complete the cleaning of the inner wall of the pipe. At the same time, a layer of brush is arranged on the surface of the scraper 21 to ensure that the impurities on the inner wall of the pipe are cleaned while avoiding damage to the pipe.
[0027] When the working range of the scraper 21 needs to be adjusted, pull the slide 31 sliding on the main shaft 1. Since the scraper 21 is movably connected to the slide 31 by the second connecting rod 23, the distance between the scraper 21 and the main shaft 1 can be changed after the slide 31 slides, so as to expand or reduce the rotation range of the scraper 21 to meet the cleaning work of the inner walls of circular pipes of different sizes.
[0028] During actual operation, the movable ring 32 that moves on the slide cylinder 31 rotates forward, and the annular gear 314 embedded in the movable ring 32 meshes with the auxiliary gear 310 that rotates inside the slide cylinder 31, and the auxiliary gear 310 is fixedly connected to the first bevel gear 312 in the internal cavity of the slide cylinder 31 through the gear shaft 311, and the first bevel gear 312 is meshed with the second bevel gear 313 fixed on the transmission shaft 38. Therefore, after the movable ring 32 rotates forward, the transmission shaft 38 rotates forward synchronously, and the active worm 37 fixed on the transmission shaft 38 is threadedly connected with the driven worm gear 36 fixed on the threaded rod 35. The movable ring 32 will drive the threaded rod 35 to rotate forward together, and the threaded rod 35 is mirror-set with two sections of spiral threads in opposite directions. And they are respectively threadedly connected with the plug blocks 34 sliding inside the fixed seat 33, so after the threaded rod 35 rotates forward, the two plug blocks 34 will synchronously slide toward the fixed seat 33 and disengage from the main shaft 1. Because the fixed seat 33 is fixed on the slide cylinder 31, after the plug blocks 34 are no longer in contact with the main shaft 1, the slide cylinder 31 can slide on the main shaft 1 to adjust the state of the scraper 21. After loosening the movable ring 32, under the action of the return torsion spring 39 fixedly connected to the movable ring 32 and the slide cylinder 31 at both ends, the movable ring 32 rotates in the opposite direction to return to the initial position. Through the transmission of the above structure, the threaded rod 35 rotates in the opposite direction synchronously, driving the plug blocks 34 to slide toward the main shaft 1 and insert into the inside of the main shaft 1, limiting the sliding of the fixed seat 33 and the slide cylinder 31, and thereby locking the state of the scraper 21.
