本文提出了一种新型水力自动闸门,该闸门利用闸门自重和水的重力怍用,自动启闭并且保持上游水位基本恒定。闸门由一个常规弧形闸门和设在门轴之后的水箱组成,通过布置在闸墩内的管道系统向水箱供水。当上游水位超过预定水位时,水箱充水,闸门开启。一个简易的缓冲装置防止闸门作不规则的摆动,在闸门从全关过渡到全开位置时,门上游水位仅仪升高10cm左右。 In this paper, a new type of hydraulic automatic gate is proposed, which uses gate weight and gravity of water to automatically open and close and keep the water level in the upstream substantially constant. The gate consists of a conventional radial gate and a water tank located behind the gate shaft, which supplies water to the tank through the piping system arranged in the gate pier. When the upstream water level exceeds the predetermined level, the water tank, water gate open. A simple buffer device to prevent irregular swing gate, the gate from the full-closed transition to the fully open position, the water level just upstream of the door elevated about 10cm.
