Sudden-expansion and sudden-fall radial gate rear side wall aeration structure
The invention discloses a sudden-expansion and sudden-fall radial gate rear side wall aeration structure, and belongs to the field of water conservancy and hydropower. The structure comprises a radial gate, side walls, a bottom plate, a ventilation shaft, a sudden-expansion and sudden-fall water stop mechanism and side wall aeration mechanisms, wherein the side walls are located on the two sides of the bottom plate, a water flow channel is formed between the side walls and the bottom plate, the radial gate is installed on the water flow channel, the ventilation shaft is located on the downstream of the radial gate and communicates with a cavity area on the top of downstream flood discharge water flow, the sudden-expansion and sudden-fall water stopping mechanism is located on the upstream of the radial gate, and the side wall aeration mechanisms are located on the two side walls of the downstream of the ventilation shaft. According to the side wall aeration structure, under the condition that the width of an original flood discharge tunnel is not expanded, the multiple stages of side walls which are shrunk inwards firstly and then expanded laterally are arranged on the two side walls of the downstream of the ventilation shaft, water flow passes through the multiple stages of side walls after impacting the side walls through the gate, the water flow is fully aerated, the water flow on the side walls does not have a clear water area any more, and the side walls are not subjected to cavitation damage any more.
本发明公开了一种突扩突跌弧形闸门后侧墙掺气结构，属于水利水电领域，包括弧形闸门、边墙、底板、通风井、突扩突跌止水机构和侧墙掺气机构；边墙位于底板两侧，边墙和底板间形成水流通道，弧形闸门安装在水流通道上，通风井位于弧形闸门下游且连通下游泄洪后水流顶部的空腔区域，突扩突跌止水机构位于弧形闸门上游，侧墙掺气机构位于通风井下游的两侧边墙上。本发明提供的侧墙掺气结构，在不扩宽原泄洪洞宽度的条件下，通过在通风井下游的两侧边墙上设置多级呈先向内收缩后侧扩的侧墙，水流通过闸门冲击边墙后，经过多级侧墙，水流充分掺气，侧墙水流不再出现清水区，边墙不再出现空蚀破坏。
