An automated cleaning device and method for marine pipes

This invention relates to the technical field of pipeline cleaning and discloses an automated cleaning device and method for marine pipelines. To solve the problem of excessive waste of cleaning fluid during pipeline cleaning, a cleaning piston and a brush plate are installed on the end of a toothed pusher. When cleaning batches of marine pipe fittings, the cleaning piston is fitted inside the pipe fitting, and the tilting assembly is adjusted to make the tilting frame relatively tilted. This ensures that the cleaning fluid input into the pipe will gather at one end of the cleaning piston and immerse the brush plate. As the brush plate rotates, the inner wall of the pipe containing the cleaning fluid is subjected to high-intensity scrubbing by the brush plate, achieving efficient cleaning of the inside of the pipe. At the same time, the forward movement of the toothed pusher not only changes the brushing position of the brush plate but also uses the cleaning piston to scrape the inside of the pipe, thereby reducing the residue of cleaning fluid. Ultimately, it achieves the effects of tilted water storage cleaning and scraping to prevent residue.
