AI Technical Summary
The inner diameter of pipes in municipal road drainage systems varies greatly, and silt adheres to the inner wall, making it difficult for existing dredging devices to effectively remove silt from pipes of various sizes.
A high-efficiency municipal drainage dredging device was designed, comprising a bracket, an electric push rod, a motor, a sliding frame, a fixing mechanism, and an unlocking mechanism. The motor drives the scraper to rotate and utilizes the adjustable spacing of the scraper to adapt to different pipe sizes. Combined with the electric push rod, the device extends into the pipe to perform dredging operations.
It has achieved stable dredging of pipes of different sizes, improved dredging efficiency and applicability, and ensured the effective removal of sludge from the inner wall of the pipe.
