一、概述湖北省大悟县界牌水库渠首泄洪闸,系一座后水箱式水力自动控制的弧形钢闸门(见图1)。这种闸门,不用配置动力机械或电器控制设备,只靠闸门自重和后水箱中充水的重力作用来控制闸门的自动启闭。闸门在运行时,保持上游水位恒定,并能自行调节闸门的开度,具有便于管理和运行安全。节省投资等特点。
First, an overview of the dam in Dawu County, Hubei Province, the first flood discharge sluice gate, Department of a water tank hydraulic automatic control of the arc-shaped steel gate (see Figure 1). This gate, do not configure the power machinery or electrical control equipment, only rely on the weight of the gate and the water tank after the gravity of gravity to control the automatic gate opening and closing. When the gate is in operation, the water level in the upper reaches is kept constant and the opening degree of the gate can be adjusted by itself, which is convenient for management and operation safety. Save investment and other characteristics.
