A flood control dam with mud-water separation device

Abstract

The invention discloses a flood control dam with a mud-water separation device, which comprises a dam, including a bottom surface and a water-facing surface, and a dam mouth is provided at an angle between the bottom surface and the water-facing surface; a mud diversion device, including driving equipment and A shut-off valve connected to the driving device, the shut-off valve is located at the mouth of the dam, and blocks the mouth of the dam when the shut-off valve is closed; a stirring tank, the mouth of the stirrer and the mouth of the dam It communicates with the mud-water separation device through a pipeline provided with a water pump; the mud-water separation device includes an inner wall that is set as a hollow inverted cone structure, and the feed inlet of the mud-water separation device is located at the top of the inner wall, and the inlet The water outlet direction of the feed port is tangent to the cross-section of the mud-water separation device where the feed port is located, and a plurality of mesh holes are arranged on the inner wall, and the mud water ejected from the feed port flows along the The spiral downward flow of the inner wall makes the muddy water move centrifugally, and the water in the muddy water is thrown out from the mesh to collect the sediment accumulated at the bottom of the dam.

Description

technical field [0001] The invention relates to the field of small flood control dams, in particular to a flood control dam with a mud-water separation device. Background technique [0002] A dam is a water-retaining structure that intercepts the water flow of a river channel to raise the water level or regulate the flow. However, the existing dams all have an inclined water-facing surface, that is, there is a certain angle between the water-facing surface and the river ground. When the river water hits the dam, the water-facing surface can intercept the river flow while buffering part of the potential energy of the water flow, preventing the river from Across the dam, thus having the effect of flood control. [0003] However, when the river water flows to the upstream side of the dam, the flow of the river will carry some sediment and wash it to the upstream side of the dam. When the dam is closed, the fluidity of the water is poor, making the sediment easy to accumulate o...

Problems solved by technology

[0003] However, when the river water flows to the upstream side of the dam, the flow of the river will carry some sediment and wash it to the upstream side of the dam. When the dam is closed, the fluidity of the water is poor, making the sediment easy to accumulate on the upstream side of the dam. The angle between the water surface and the river ground; in the long run, it will lead to more and more sediment accumulation, and even affect the flood control effect of the dam
