the screw assembly is provided with at least one high-pressure cleaning spray head which is suitable for spraying high-pressure water to the pipe wall of the metal water supply pipeline.
7. The use method of the repair pretreatment device for the metal water supply pipeline is characterized by comprising the following steps:
step S1, closing a valve of a pipe section to be processed in the metal water supply pipeline, stopping water supply, opening an inspection well or excavating a working foundation pit to serve as the inspection well, opening the pipeline, carrying out CCTV detection, installing a power mechanism, a pneumatic rotating gear mechanism and a screw rod assembly, wherein the screw rod assembly is prepared by connecting a plurality of sections of screws in series, and connecting a hard grinding wheel with the front end of the screw rod assembly;
step S2, starting a power mechanism to provide power for a pneumatic rotating gear mechanism, wherein the pneumatic rotating gear mechanism rotates forwards to drive a screw rod assembly to rotate forwards in a metal water supply pipeline so that a hard polishing wheel can remove impurities on the inner wall of the metal water supply pipeline, and meanwhile, a screw rod is additionally arranged at the rear end of the screw rod assembly step by step;
step S3, after the hard grinding wheel completely passes through the section of pipeline, the hard grinding wheel is disassembled, the power mechanism drives the pneumatic rotating gear mechanism to rotate reversely, the screw assembly rotates and moves backwards in the metal water supply pipeline, and meanwhile, the recovery screw is disassembled step by step at the rear end of the screw assembly;
and S4, disassembling the pneumatic rotating gear mechanism and the power mechanism, completing the pipeline pretreatment construction, and performing CCTV detection again.
8. The use method of the device for repairing and pretreating a metal water supply pipe according to claim 7,
in the step S1, a hard wire scraping wheel and a common wire brush scraping wheel are sequentially mounted on the screw assembly; and
in the step S3, after the hard grinding wheel, the hard steel wire scraping wheel and the ordinary steel wire brush scraping wheel completely penetrate through the section of the pipeline in sequence, the hard grinding wheel, the hard steel wire scraping wheel and the ordinary steel wire brush scraping wheel are dismounted in sequence.
9. The use method of the device for repairing and pretreating a metal water supply pipe according to claim 7 or 8,
in step S2, while the screw assembly moves forward in the metal water supply pipe, the power mechanism provides high-pressure water and jets the high-pressure water from the high-pressure water jet holes after passing through the pneumatic rotary gear mechanism and the screw assembly in sequence, and the high-pressure water washes the pipe wall of the metal water supply pipe and discharges impurities on the inner wall of the pipe after being cleaned.
10. The use method of the device for repairing and pretreating a metal water supply pipe according to claim 9,
in step S2, the screw assembly rotates and moves forward in the metal feed water pipe, and at the same time, high pressure water is sprayed through a high pressure cleaning nozzle connected to the screw assembly, so as to clean impurities on the inner wall of the pipe.
