水力自控翻板闸门设计参数分析

利用水力学水静力学基本原理建立了水力自控翻板闸门的受力平衡方程,对闸门转轴高度、闸门倾斜角和闸门底部配件重力等设计参数进行了分析。结果表明:闸门转轴距闸门底的高度应为闸前水深的1/3;在闸门为均质材料情况下,维持闸门平衡的条件是闸门配件重力应为闸门重力的1/2;闸门倾斜角对闸门自动翻倒无影响,但在闸门挡水情况下对闸门受力有较大影响。

Design parameters analysis of hydraulic automatic flap gate

Based on the basic principle of hydraulic statics,the force balance equation of a hydraulic automatic flap gate was developed to study design parameters of the gate,including the shaft height,the angle,and the gravity of bottom fitting.The results show that the height from the gate shaft to gate bottom is a third of the depth of water in the front of the gate.When the gate is homogeneous,the gravity of fitting should be one half of that of the gate to maintain the balance of the gate.The gate angle has no effect on the overturning of the gate,but has a large effect on the load of the gate as the gate retains water.
