[0029] Specifically, the synchronous controller simultaneously controls the electric push rods 403 on both sides to make them telescopically move synchronously, so that the fixed ring 402 can be synchronously moved in the direction of approaching each other, and the angle of the support rod 404 is changed under the action of the moving seat 407 and the fixed rod 406, thereby changing the inclination angle, and making the moving component 405 contact the inner wall of the petrochemical pipeline at the same time, thereby saving adjustment time and improving adjustment efficiency. The moving component 405 includes a drive motor, a rotating shaft and a roller, so that the roller can move along the inner wall of the petrochemical pipeline.

[0030] Example 2

[0031] See Figure 4, and on the basis of Example 1, it is further obtained that the adjustment mechanism 5 also includes a communicating hole 501 opened on the outer wall of the circular column 3, and the number of communicating holes 501 is set. The multiple communicating holes 501 are connected to the piston groove 502 and pass through the first disc 1. The inner wall of the piston groove 502 is provided with a piston block 503. The piston groove 502 is fixedly connected to a fixed block 504 on the side corresponding to the piston block 503. The fixed block 504 is fixedly penetrated by an electric telescopic rod 505. The telescopic end of the electric telescopic rod 505 is fixedly connected to the piston block 503.

[0032] Specifically, the electric telescopic rod 505 pushes the piston block 503 to move, thereby squeezing the hydraulic oil in the piston groove 502 and allowing the hydraulic oil to pass through the connecting hole 501 into the hydraulic cylinder 507, thereby pushing the piston column 508 to move, and sliding up and down without rotating, so that the scraper 509 can be in close contact with the inner wall of the petrochemical pipeline, thereby completely scraping off impurities on the inner wall of the petrochemical pipeline to prevent loosening and incomplete cleaning.

[0038] Specifically, the motor 701 drives the driving shaft 702 and the gear 703 to rotate, thereby driving the gear ring 704 to rotate, and driving the rotating ring 506 to rotate, thereby providing power support for the cleaning operation.

[0039] During the actual operation, the first disc 1 is first placed into the petrochemical pipeline, and then the entire device is placed in the petrochemical pipeline. Then, the synchronous controller controls the electric push rod 403 to push the fixed ring 402 to move in the direction of approaching each other, thereby moving the fixed rod 406, and the moving seat 407 slides along the surface of the support rod 404, thereby changing the inclination angle of the support rod 404 and making the roller in the moving component 405 contact the inner wall of the petrochemical pipeline.

[0041] During scraping, water can be injected into the sealing ring 602 and the connecting ring 601 through the water inlet pipe 603, and enter the connecting block 604 through the hose, and then sprayed out through the nozzle 605 to clean the scraped inner wall again, thereby further improving the cleaning effect;

[0042] Then the motor 701 is started to rotate the driving shaft 702 and the gear 703, and the gear 703 rotates the gear ring 704 and the rotating ring 506, so that scraping and cleaning can be performed.
