Abstract
The utility model provides a road drainage project anti-blocking device which comprises a cleaning unit used for cleaning the interior of a drainage pipeline, the cleaning unit comprises a propelling spray head connected with a water supply unit, and the front end of the propelling spray head is detachably connected with a plurality of rotary propelling spray pipes with high-pressure spray heads. The water supply unit is connected with a winding unit used for pulling back the propelling nozzle, and an adjusting unit used for keeping the propelling nozzle to move horizontally is arranged on the winding unit. A plurality of detachable rotary propelling spray pipes are matched with high-pressure water flow, blockages on the inner wall of the pipeline can be impacted at multiple angles, and the dredging efficiency is remarkably improved; the cleaning unit can be pushed into the pipeline through high-pressure water flow and can also be pulled back through the winding unit, two-way cleaning is achieved, and residual blockage is avoided.
