Water taking structure for bottom barrier dam
The invention relates to the technical field of water conservancy and hydropower engineering, in particular to a water taking structure for a bottom barrier dam. The water taking structure comprises achannel, a water taking pipeline, a grit chamber, a flow guide structure, a bottom barrier and a lifting device used for lifting one side of the bottom barrier. The channel is transversely arranged on a riverbed, the grit chamber is formed in a river bank and the flow guide structure is arranged on the river bank. The channel, the water taking pipeline, the grit chamber and the flow guide structure are sequentially connected. The channel comprises a first channel wall located on the upstream side and a second channel wall located on the downstream side. One end of the bottom barrier is embedded in the first channel wall, and the other end of the bottom barrier is embedded in the second channel wall and hinged to the second channel wall. According to the water taking structure, by additionally arranging the lifting device, when the water taking amount is greatly decreased due to blockage of the bottom barrier by floating objects, the side, embedded in the first channel wall, of the bottom barrier is lifted, the floating objects fall off under reverse scouring of upstream water flow, and the water taking efficiency is improved under the condition that the bottom barrier dam does notneed to be cleaned.
本发明涉及水利水电工程技术领域，具体是一种用于底栏栅坝的取水结构，包括渠道、取水管道、沉砂池、导流结构、底栏栅和用于将底栏栅一侧举起的升举装置；所述渠道横设在河床上，所述沉砂池和导流结构设置在河岸上；所述渠道、取水管道、沉砂池和导流结构依次连接；所述渠道包括位于上游侧的第一渠墙和位于下游侧的第二渠墙，所述底栏栅的一端嵌设在第一渠墙上，另一端嵌设在第二渠墙上，并与第二渠墙铰接；该取水结构通过添加所述升举装置，在所述底栏栅因漂浮物阻塞而导致取水量大幅下降时，将底栏栅嵌设在第一渠墙上的一侧抬升，使得漂浮物在上游水流的反向冲刷下脱落，达到了在无需对所述底栏栅坝进行清理的条件下，提高取水效率的效果。
