Water diversion type hydropower station dam ice blocking auxiliary device and construction method
The water diversion type hydropower station dam ice blocking auxiliary device comprises a lock chain, the two ends of the lock chain are tensioned at anchoring ends, and the lock chain is connected with a plurality of ice blocking floating pieces; the anchoring end comprises a sliding block and a rail sliding groove allowing the sliding block to vertically run, and the rail sliding groove is embedded in concrete through a second-stage embedded part. The sliding block is connected with the chain. By connecting the plurality of ice blocking floating pieces to the chain, connecting the chain with the sliding block and matching with the design structure of the rail sliding groove, the chain floats on the water surface all the time by utilizing the buoyancy of the ice blocking floating pieces and the sliding performance of the sliding block, and the ice blocking effect of the hydropower station dam area is achieved; therefore, ice blocks are prevented from accumulating at the spillway gate to influence normal opening and closing of the spillway radial gate and cannot adjust the water level of a reservoir area, and the problem that the ice blocks enter the diversion tunnel and finally flow into the water turbine to damage the water turbine is solved.
本发明公开一种引水式水电站大坝拦冰辅助装置及施工方法，包括锁链，锁链两端张拉在锚固端上，锁链上连接若干拦冰浮件；锚固端包括滑块和供滑块竖直运行的轨道滑槽，轨道滑槽通过二期埋件预埋设于混凝土中；滑块与锁链连接。本发明通过在锁链上连接若干拦冰浮件，将锁链与滑块连接，并配合轨道滑槽的设计结构，利用拦冰浮件的浮力以及滑块的滑动性，使得锁链时刻漂浮在水面上，实现了水电站大坝区域拦冰效果，从而防止冰块堆积在溢洪道闸口处影响溢洪道弧形闸门正常启闭，无法调节库区水位，同时也解决了冰块进入引水隧洞最后流入水轮机破坏水轮机的问题。
