Fishway inlet structure for supplementing water by using original river water flow
The invention relates to a fishway inlet structure for supplementing water by using original river water flow. The invention aims to provide the fishway inlet structure for supplementing water by using the original river water flow. The technical scheme is that the fishway inlet structure for supplementing water by using the original river water flow comprises a fishway channel body structure, and is characterized in that a water supplementing channel and a confluence channel capable of increasing the flowing speed of water flow entering the fishway channel body structure are formed in a river channel on the outer side of the downstream end of the fishway channel body structure, wherein the downstream end of the confluence channel is a fish inlet; the upstream end of the confluence channel is connected with the downstream end of the fishway channel body structure and the downstream end of the water supplementing channel; and a fish blocking grid is arranged at the downstream end of the water supplementing channel. The water supplementing channel is of a horn-shaped structure with a wide upstream and a narrow downstream; and the confluence channel is of a horn-shaped structure with a wide upstream and a narrow downstream. The fishway inlet structure is suitable for the field of water conservancy and hydropower engineering.
本发明涉及一种利用原河道水流补水的鱼道进口结构。本发明的目的是提供一种利用原河道水流补水的鱼道进口结构。本发明的技术方案是：一种利用原河道水流补水的鱼道进口结构，包括鱼道渠身结构，其特征在于：所述鱼道渠身结构下游端外侧的河道内形成有能增大进入其内水流流速的补水渠及汇流渠，其中汇流渠下游端为进鱼口，汇流渠上游端衔接鱼道渠身结构的下游端和补水渠的下游端，补水渠下游端设有拦鱼格栅。所述补水渠为上游宽、下游窄的喇叭状结构；所述汇流渠为上游宽、下游窄的喇叭状结构。本发明适用于适用于水利水电工程领域。
