Research On Variable Slope Flow Evolution Motion Test Instrument Based On Water-Sediment Separation And Environmental Protection Recovery Function

In view of the shortcomings of the traditional river model and flume test in hydraulic academia, such as the difficulty of adjusting and changing the slope, and the difficulty of separation and recycling water and sediment, a variable slope flow evolution motion test instrument based on water-sediment separation and environmental protection recovery function was developed. The variable slope flow evolution motion test instrument can control one side of the flowing water panel to rise and the other side to sink through the expansion of the electric pusher device, thus realizing the arbitrary gradient of the flowing water slope. Through the research on the instrument, innovative devices such as baffle, water and sediment separating and collecting trough and water collecting box are designed. The process of flow guiding, sediment deposition, water and sediment separating and collecting is completed. The experimental materials can be collected and recycled environmentally, and the cost of the experiment can be greatly reduced. The research on the variable slope flow evolution motion test instrument based on water-sediment separation and environmental protection recovery function can change the slope smoothly, is an innovative reform to the existing experimental instrument of water conservancy industry.
