The invention provides a laminated beam gate device for water intake of power station, which comprises a trash barrier pier, a trash barrier gate slot, a spare trash barrier gate slot and a trash barrier. The front side walls of two adjacent trash barrier piers are respectively provided with a trash barrier gate slot, and the back side walls of two adjacent trash barrier piers are respectively provided with a backup trash barrier gate slot. The utility model is characterized in that the utility model also comprises a folded-line flat laminated beam door, the folded-line flat laminated beam door is arranged in the trash rack gate groove, and the trash rack is arranged in the spare trash rack gate groove. Compared with the traditional flat laminated beam gate, under the condition that the water retaining height of the laminated beam gate remains unchanged (i.e., the effect of improving the ecological environment of the downstream river channel remains unchanged), the total head loss of the intake section of the power station can be reduced, and the power generation benefit of the power station can be improved. The invention has better social and economic benefits.

一种电站进水口分层取水叠梁门装置
本专利技术涉及水利水电建设开发与生态环境保护领域,具体是一种电站进水口分层取水叠梁门装置。
技术介绍
随着水利水电工程的不断开发,在带来巨大综合效益的同时,其环境问题日益突出,受到社会的高度关注。生态环境保护是目前水利水电工程建设面临的敏感性问题,特别是一些高坝水电站建成后,其下泄的低温水将对下游河道的生态环境产生严重影响,直接威胁着河道中各种水生生物的生存,在电站进水口前设置分层取水结构是缓解下泄低温水对下游河道生态环境不利影响的有效措施。美国20世纪60年代就对深水库电站分层取水进行了研究,其中典型的沙斯塔水坝和饿马水坝实现分层取水后,有效改善了大坝下泄水温问题,保护了下游河道生物种群结构不被破坏。目前国内外大型水电站多采用叠梁门分层取水方式,一般将叠梁门放置在拦污栅下游的备用拦污栅门槽内,通过调整叠梁门的挡水高度、使机组发电用水尽量从水库表层获取,以减轻电站发电泄水对下游河道生物及水环境造成的负面影响,特别是在鱼类产卵繁殖期,提高下游河道的水温犹其重要;但放置叠梁门后将恶化电站进水口的水流条件,显著增加进水口段的水头损失,从 ...
