摘要:
泵站、水电站等水利工程下游检修门止水效果往往不佳，根本原因在于检修门在静水中启闭，无正向水平水压力作用，止水不能较好的贴合踏面。采用4 个弹压支承安装在闸门背面，2 个安装在两侧端梁顶部适当位置，另2 个安装在两侧端梁下半截适当位置。弹压支承主要由弹簧、滚轮、圆管、方管等组成，圆管设底板，弹簧置于圆管内，另一端支承滚轮。为防止滚轮运行中偏转，设置一根方管，一端与滚轮支座焊连，从弹簧中穿过，另一端穿过圆管底板中部预留的方孔后锁定。弹压支承圆管部分固定在检修门上，滚轮支承在门槽反轨上，使弹簧发生设计压缩量，对闸门产生推力，强迫闸门止水贴合踏面，增强止水效果。
Abstract:
Pump station，hydropower station，such water conservancy project downstream gate water seal effect is often poor，the fundamental reason lies in the opening and closing of the door in still water，there is no positive level of water pressure.Four elastic supports are arranged on the back of the gate.Two of them are installed on both sides of the top beam，and the other two are installed on both sides of the lower half of the beam.The support is mainly composed of spring，roller，round tube and square tube.The circular tube is provided with a bottom plate.The spring is arranged in a circular tube，the other end is provided with a supporting roller.A square tube is connected with the roller support at one end，and passes through the spring.The other end passes through the square hole which arranged in the middle part of the circular tube.The supporting pipe part is fixed on the access door.The roller is supported in the reverse track of the door.Making the spring to compress，thrusting on the gate，forcing the gate seal fitting the tread，finally enhanced the sealing effect.
