Channel cleanout device

The utility model discloses a channel cleanout device, which comprises a ship body. A water suction pump and a sludge suction pump are arranged on the ship body. The water suction pump is connected with a water suction pump water inlet pipe and a water suction pump water outlet pipe. The water suction pump water outlet pipe is connected with a booster pump which is connected with a high-pressure water gun. The high-pressure water gun extends to a part below the ship body. The sludge suction pump is provided with a sludge suction pump water inlet pipe and a sludge suction pump water outlet pipe. The sludge suction pump water outlet pipe is connected with a centrifugal separator. The centrifugal separator is provided with a centrifugal separator drainage pipeline and a centrifugal separator sludge discharging pipeline. The centrifugal separator sludge discharging pipeline is connected with a sludge collector. The channel cleanout device provided by the utility model is simple in structure and convenient to use; and when the channel cleanout device works, water in a river is not required to completely pumped, and meanwhile, the influence of a lining slope of a river channel is avoided.
