[0002] When cleaning the urban sewer network, the suction pipe is usually extended into the sludge well. The suction pump connected to the suction pipe can pump out the sludge in the sludge well, thereby completing the cleaning of the sludge well. The suction device is often installed on a vehicle to clean the urban sewer network more quickly. The general high-tech environmental protection suction device is equipped with a set of suction pipes, the bottom end of which is extended into the bottom of the sludge well, and the suction pump at the other end of the suction pipe performs the suction operation.
