Sweeping and suction desilting machine for floating sludge and flowing sludge of drinking water reservoir and desilting method thereof

Abstract

The invention discloses a sweeping and suction desilting machine for floating sludge and flowing sludge of a drinking water reservoir and a desilting method of the sweeping and suction desilting machine. The sweeping and suction desilting machine comprises a suction cavity body, wherein the suction cavity body is connected with a dredge pump of a workboat through a pipeline, suction inlets are formed in the two sides of the suction cavity body and are hinged to movable cover plates respectively, hydraulic cylinders are hinged to the suction cavity body, one end of a movable rod of each hydraulic cylinder is hinged to the corresponding movable cover plate, a bottom cavity in the suction cavity body is arranged in the mode that the interior is high and the exterior is low, and vertical guide plates are fixedly arranged on the suction inlets and located in the bottom cavity. According to the sweeping and suction desilting machine for the floating sludge and the flowing sludge of the drinking water reservoir and the desilting method of the sweeping and suction desilting machine, due to the characteristics that the floating sludge and the flowing sludge on the bottom layer of the drinking water reservoir are high in fluidity, the diameter of sludge particles is small, and the sludge particles can easily move and diffuse, the dredge pump on the workboat is used for providing vacuum suction, the floating sludge and the flowing sludge are sucked out through the sweeping and suction desilting machine in slight fan-shaped swing in the unidirectional slow sweeping and suction mode that sweeping is carried out on the left side when suction is carried out on the left side, and sweeping is carried out on the right side when suction is carried out on the right side, and the desilting purpose is achieved. The sweeping and suction desilting machine and a construction process provide good technology and equipment support for removal of the floating sludge and the flowing sludge of the reservoir, and the popularization and application value is remarkable.

Description

technical field [0001] The invention relates to a dredging machine tool and a dredging method thereof, in particular to a dredging machine tool and a dredging method for floating mud and flowing mud at the bottom of a drinking water reservoir. Background technique [0002] Reservoirs have comprehensive utilization functions such as flood control, irrigation, water supply, and power generation, and play an irreplaceable important role in economic development and environmental protection. my country has a vast territory and many reservoirs, most of which were built in the 1970s and 1980s. Most of them lack effective sediment discharge design. After years of operation, sedimentation is common, which seriously weakens the effective storage capacity of the reservoir and affects The benefits of the reservoirs are normally exerted, and even the operation of the reservoirs is affected. Some reservoirs are seriously silted up and are in the state of being scrapped. Due to the differe...
