Hydraulic self-ploughing type sludge suction head

Abstract

The invention relates to a hydraulic self-ploughing type sludge suction head. The hydraulic self-ploughing type sludge suction head is characterized in that a steel pipe, impeller sets, rectification sheets, a driving shaft, a driven shaft, gear sets, bearings, plows, a filter screen and a protection cover are included. The impeller sets and the rectification sheets are arranged in the steel pipe, the rectification sheets are fixed to the inner wall of the steel pipe, the driving shaft penetrates through the bearings in the centers of the rectification sheets, the gear sets are fixed to the driving shaft and the driven shaft, the bearings are embedded in gears, the plows are welded to the gear sets, a water inlet of the steel pipe is sleeved with the filter screen, and all the components are sealed in the protection cover. Impellers in the steel pipe can be driven by the energy of high-speed water flow in an outer sand conveying pipeline to rotate at high speed, sludge settled at the bottom of a reservoir can be easily stirred by force finally acting on the plows, and the effect of integrally reservoir underwater dredging and sand discharging can be achieved without other power source devices.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and in particular relates to a hydraulic self-cultivation dredging head for removing silt deposited in a reservoir. [0002] Background technique [0003] There are 86,000 reservoirs in my country, most of which were built in the 1950s and 1960s. They lack effective sediment discharge design. After many years of operation, sedimentation has generally occurred, which has seriously reduced the capacity of the reservoir. The silt deposition in the reservoir reduces the storage capacity of the reservoir and reduces the water storage capacity, especially in the northwest region, where the rivers have a large amount of sediment, and the reservoirs silted up by the silt even completely lose their reservoir functions. Some reservoirs are designed with sand discharge bottom holes, but they can only discharge the sediment near the bottom hole door, and the large flow of sand discha...

Problems solved by technology

The disadvantage of this device is that it needs to provide a lot of power energy to vibrate the silt, and use the suction pump to discharge the silt
