Overflow slag collecting weir for water conservancy and hydropower engineering
The overflowing slag collecting weir comprises a slag stopping structure, a slag collecting structure and a slope which are arranged in the river direction, and a first lifting device and a second lifting device which are used for driving the slag collecting structure and the slag stopping structure to ascend and descend correspondingly. The slag blocking structure filters rock ballast in water to enable the rock ballast to settle towards the bottom of a riverbed, the slag collecting structure collects the rock ballast, the slope supports the back face of the slag collecting structure to improve the water flow impact resistance of the slag collecting structure, and the slag blocking structure is arranged on the upstream instead of the downstream of the slag collecting structure. The rock ballast filtering performance of the device cannot be affected, a rock ballast accumulation area cannot appear at the downstream of the slag collecting structure, meanwhile, the slag collecting structure and the slag stopping structure can ascend and descend, and therefore the work of descending the slag collecting structure, ascending the slag stopping structure to collect rock ballast and ascending the slag collecting structure and descending the slag stopping structure to clean the rock ballast can be executed.
本发明公开了一种水利水电工程用的过流集渣堰，包括沿着河流方向布置的挡渣结构、集渣结构和坡，以及分别用于驱动集渣结构和挡渣结构升降的第一升降装置和第二升降装置。挡渣结构过滤水中的石渣，使得石渣向河床底部沉降，集渣结构收集石渣，坡支撑集渣结构的背面以提高其抗水流冲击性能，将挡渣结构设置在集渣结构的上游而非下游，即使挡渣结构长期受到石渣的冲击而出现变形，也不会影响其过滤石渣的性能，更不会导致集渣结构的下游出现石渣的堆积区域，同时，集渣结构和挡渣结构均可以升降，从而可以执行集渣结构下降、挡渣结构升起以收集石渣，以及集渣结构升起、挡渣结构下降以清理石渣的工作。
