浮体驱动式双叶对向水力自控闸门研究

Research on Floating Body-Driven Double-Leaf Opposed Hydraulic Self-Controlled Gate

摘要:

传统闸门由外动力控制,而闸门本身自重大,水压力大,所需提升力大,电能消耗大。浮体驱动式双叶对向水力自控闸门以上游水源为动力,通过调节进水阀和放水阀,控制浮体室内水位的升降,进而控制浮体的升降,控制闸门转动,实现水力自控。且无电力消耗,无需配套设施。通过模型试验,确定浮体室水位上升高度与闸门开度的关系。分析闸门前后的水流流态,探究不同流量及不同闸门开度条件下，上下游水深及流速特性，为实际应用提供理论依据。

Abstract:

Traditional gates are controlled by external power. However, the gates themselves are heavy, subject to largewater pressure, requiring large lifting force and resulting in high power consumption. The floating body-drivendouble-leaf opposed hycdraulic self-eontrolled gate uses upstream water as power. By adjusting the water inlet valve anddrain valve, it controls the rise and fall of the water level in the floating chamber, thereby driving the floating body to lift orlower and controlling the rotation of the gate to achieve hycdraulic self-control. It has no power consumption and does notrequire supporting facilities. Through model tests, the relationship between the water level rise in the floating chamberand the gate opening is determined. The flow patterns around the gate are analyzed, and the water depth and velocilycharacteristics upstream and downstream under different flow rates and gate openings are explored, providing atheoretical basis for practical applications.
