Flow-dividing sand discharging device and sand discharging method for barrier type inlet in channel
The invention discloses a split-flow desilting device for a barrier type inlet in a channel, which comprises a silt concentration monitor, one side of the silt concentration monitor is provided with a split-flow port, and two opposite sides of the split-flow port are respectively provided with a first silt separating device and a second silt separating device. The silt concentration monitor is designed at the bottom of the channel, and water flow information such as the silt content and the silt granularity of water flow in the channel can be monitored and collected in real time besides flow dividing and silt discharging integrated with a barrier type inlet and a valve; the two independent sand conveying channels with the valves are arranged in the device, it is guaranteed that water flows with different sand concentrations do not affect each other in the flow dividing and sand conveying process, flow dividing has selectivity, the sand discharging water consumption rate of the device is reduced to a greater extent, and the water discharging time of a water discharging hole of the water dividing device is shortened.
本发明公开了渠道内栏栅式进口的分流排沙装置，包括泥沙浓度监测器，泥沙浓度监测器的一侧设有分流口，分流口相对两侧分别设有第一分沙装置和第二分沙装置。本发明在渠道底部设计了泥沙浓度监测器，在实现与栏栅式进口、阀门一体化的分流排沙外，还可实时监测并收集渠道内水流的含沙量、泥沙粒度等水流信息；装置中设置了两个独立带有阀门的输沙通道，保证在分流输沙过程中不同含沙浓度的水流互不影响，使分流具有选择性，更大程度上降低了装置的排沙耗水率，缩短了分水装置排水孔的排水时间。
