AI Technical Summary
Existing water conservancy pipeline inner wall cleaning machines have high frictional resistance between the brushes and the inner wall of the pipeline, resulting in low cleaning efficiency and dirt easily adhering to the brushes.
The internal support walker drives the mounting cylinder to move. The first motor drives the turntable to rotate, and the second motor drives the roller brush to rotate. Combined with the scraper to remove dirt, the roller brush uses centrifugal force to throw out the dirt, and the nozzle sprays high-pressure water jets for secondary rinsing.
It effectively reduces the contact area between the roller brush and the inner wall of the pipe, reduces friction, improves cleaning efficiency, reduces dirt adhesion, and enhances the cleaning effect.
