Air jet type pipeline decontamination machine

The invention relates to the field of jet propulsion application, in particular to a jet propulsion pipeline decontamination machine, which includes a fuselage and a fixing frame provided on the left side of the fuselage. In the gear lever fixedly connected to the fuselage, four guide grooves opening outward are symmetrically distributed in the center of the end wall of the fixed frame, and left and right symmetrical moving blocks are slidably arranged in the guide groove. The moving block is provided with left and right threaded holes with reverse threads passing through the left and right, and the threaded holes are internally connected with threaded rods. The jet propelled pipeline decontamination machine provided by the present invention can realize the sludge in the pipeline. For cleaning, the equipment uses jet propelling equipment to drive the scraper to the depth of the pipeline. When it moves to the maximum limit, it drives the scraper to abut against the pipe wall, and then pulls the scraper to the outside of the pipe through the wire drawing device, thereby contaminating the inner wall of the pipe Mud scraping, the device of the invention is completely scraped, and the scraping force is large, which is more efficient.
