Lifting gate for water taking of reservoir vertical shaft and working method
The invention relates to the technical field of water conservancy projects, in particular to a lifting gate for water taking of a reservoir vertical shaft and a working method. The upper end of the gate is hoisted on a supporting platform above the vertical shaft through a hoisting device, and the gate directly faces a gate groove in the bottom of the vertical shaft. The gate comprises a gate body, a conical head and a water stop device. The gate body serves as a framework of the whole gate and comprises a plurality of sliding strips matched with the guide rails, a connecting sleeve is arranged in the center of the gate body and serves as a unique channel for communicating upper and lower waterways of the gate, and the bottom of the connecting sleeve penetrates through the water stop device. A fixed connecting frame is arranged above the gate body, a sliding connecting frame fixed to the conical head is arranged on the fixed connecting frame, and the lifting device drives the sliding connecting frame to move up and down through a hoisting assembly so as to open and close the connecting sleeve. The water stopping device is arranged at the bottom of the gate body and used for blocking gate grooves in the bottom of the vertical shaft. The problems that an open type gate cannot be in direct butt joint with a water conveying pipeline, opening and closing and accurate positioning are not easy, and meanwhile water stop rubber is difficult to replace are solved.
本发明涉及水利工程技术领域，具体为一种用于水库竖井取水的升降闸门及工作方法。该闸门的上端通过起升装置吊装于竖井上方的支撑平台上，闸门正对竖井底部的门槽；闸门包括闸门主体、锥头以及止水装置；闸门主体作为整个闸门的骨架，包括与所述导轨配合的多个滑条，闸门主体中心处设有连接套筒，连接套筒作为闸门上下方水路连通的唯一通道，其底部贯通止水装置；闸门主体上方设有固定连接架，固定连接架上设有与锥头固定的滑动连接架，起升装置通过吊装组件带动滑动连接架上下移动从而打开和关闭连接套筒；止水装置设在闸门主体底部，用于封堵竖井底部的门槽。解决了开敞式闸门无法直接对接输水管道，不易启闭和精确定位、同时止水橡胶替换困难等问题。
