摘要
近年来,随着我国高坝大库的建设持续推进以及对生态环境的日益重视,减小水库下泄水温与出入库水温差异的需求愈发迫切。通过分析国内外传统分层取水设施和当前国内分层取水主要实施方案的特点,针对其在适用范围、布置设计及运行维护中存在的问题和不足,综合业内关于新型分层取水设施的研究和设计工作,重点介绍了多种水电站进水口新型分层取水设施布置设计方案。这些新型设施普遍具备取水深度灵活可控、下泄水温调节精准度高、操作便捷及工程适应性强等优势,可为有类似需求的水电工程的设计建设提供一定参考借鉴。
In recent years,with the continuous advancement of high-dam and large-reservoir construction in China and the growing emphasis on ecological conservation,there has been an increasingly urgent demand to mitigate the temperature difference between the discharged water and the incoming/outgoing reservoir water.Through an analysis of the characteristics of traditional stratified water intake facilities worldwide and current domestic implementation approaches for layered water withdrawal,this study addresses the limitations and challenges in their applicability,layout design,and operational maintenance.By synthesizing industry research and design efforts on innovative stratified water intake solutions,it highlights multiple novel layout and design schemes for intake structures in hydropower stations.These next-generation facilities generally demonstrate advantages including flexible and controllable intake depth,high-precision regulation of discharged water temperature,user-friendly operation,and strong engineering adaptability,which provides valuable references for the design and construction of water conservancy and hydropower projects with similar requirements.
