Abstract

The invention discloses a silt loss preventing device for river ecological restoration. The silt loss preventing device comprises a river channel, wherein a silt conveying device for intercepting andconveying silt is arranged in the river channel; a flow control device positioned on the lower side of a filter screen is arranged in the river channel; the flow control device can adjust the silt conveying amount according to the water flow speed; and a storage device for storing redundant silt is arranged on the right side of the river channel. According to the silt loss preventing device, the silt in the river channel is intercepted through the intercepting filter screen arranged on the river channel, meanwhile, a water turbine positioned on the upstream of the intercepting filter screen drives a conveying mechanism to convey the intercepted silt into a conveying channel, water flow containing the silt is guided into a downstream farmland to be improved through the conveying channel, and therefore water and soil loss in the river channel is intercepted and guided, and the downstream farmland can be irrigated and improved; and meanwhile, a flow adjusting mechanism can automatically adjust the water conveying amount of the conveying channel according to the rainfall, the drought condition of the downstream farmland can be relieved, and the downstream flood disaster can be reduced.

Description

technical field [0001] The invention relates to the technical field of sediment loss prevention, in particular to a sediment loss prevention device for ecological restoration of rivers. Background technique [0002] Soil erosion refers to the phenomenon that due to the influence of natural or human factors, rainwater cannot be absorbed on the spot, flows downhill, and scours the soil, resulting in simultaneous loss of water and soil. Water and soil erosion will cause silting of rivers, channels, and reservoirs, reducing the benefits of water conservancy projects. It even leads to floods and droughts, seriously affecting industrial and agricultural production, and soil erosion poses a serious threat to agricultural production in mountainous areas and downstream rivers. In the downstream farmland, the current control of water and soil loss is mainly to strengthen the upstream soil to prevent its loss. At present, there is no equipment for intercepting and diverting water and s...
