后水箱水力自动控制弧形闸门是武汉水利电力学院负责主持研制试验,湖北省孝感地区水利局,湖北省大悟县水利局配合设计、施工试制成功的。它主要由门叶、缓冲箱、臂杆、枢轴、后水箱和一条专门的输水系统组成。(见附图)。其主要工作原理是在上游水位流量变化时,通过输水系统调节后水箱的充水量,从而利用闸门自重和水的重力作用以及力矩平衡原理,使得闸门能够自动启闭,保持上游水位基本恒定。当闸门上游水位低于设计要求的控制水位,亦即低于设在闸墩内的溢流堰的堰顶高程时,溢流 After the tank hydraulic automatic control of the radial gate Wuhan Institute of Water Conservancy and Electric Power is responsible for presided over the development of experiments, Xiaogan region of Hubei Province Water Conservancy Bureau, Hubei Province Dawu County Water Conservancy Bureau with the design, construction trial success. It mainly consists of door leaf, buffer box, arm, pivot, rear water tank and a special water delivery system. (see Attachment). The main working principle is that when the upstream water level flow changes, the water filling capacity of the water tank is adjusted by the water delivery system, so that the gate can automatically open and close with the gravity of the gate and the gravity of the water as well as the water level in the upper reaches basically constant. When the water level upstream of the gate is lower than the control level required by the design, ie below the crest elevation of the weir in the pier, the overflow
