Overflow structure capable of automatically adjusting water depth in vertical seam type fishway
The invention discloses an overflow structure capable of automatically adjusting the water depth in a vertical seam type fishway, and relates to the technical field of hydraulic engineering construction, the overflow structure comprises multiple stages of overflow joints which are connected in series, the overflow joint at the head position is connected with a fishway outlet section pool chamber, and the overflow joint at the tail position is connected with a fishway inlet section pool chamber; an overflow gap is formed in each stage of overflow joint; and a height difference is formed between the adjacent overflow gaps, so that the water depth of each stage of overflow section is gradually reduced in the direction from the fishway outlet section pool chamber to the fishway inlet section pool chamber. According to the overflow structure, the functions of automatically overflowing redundant flow and adjusting the water depth in the fishway are achieved under the condition that the outlet is formed, so that the water falling phenomenon caused by mismatching of upstream and downstream water levels and the fact that the water depth of the outlet section is larger than that of the inlet section is eliminated, and the requirement for fish upstream is met.
本发明公开了一种可自动调节竖缝式鱼道内水深的溢流结构，涉及水利工程建设技术领域，它包括多级相互串接的溢流节，首部位置的溢流节与鱼道出口段池室相连接，尾部位置的溢流节与鱼道入口段池室相连接，每级溢流节上均开设有溢流缺口；其中，相邻溢流缺口之间形成高差，以使沿鱼道出口段池室至鱼道入口段池室的方向，每级溢流节的水深逐级降低。该溢流结构通过设置一个出口的情形下实现自动溢出多余流量、调节鱼道内水深的工鞥，从而消除因上下游水位不匹配、出口段水深大于进口段水深而引发的跌水现象，满足鱼类上溯的要求。
