Fish passing river channel device suitable for shallow water return river reach
The fish passing river channel device comprises a hydropower station, a fishway and a river channel, the hydropower station comprises a main body section, the downstream of the hydropower station is provided with a downstream water return level, the fishway is arranged on one side of the hydropower station, and the fishway comprises a fishway inlet, a fishway channel body and a fishway outlet; the river channel is arranged between the fishway inlet and the downstream water return level and comprises a first channel body and a second channel body, the first channel body is arranged on the side where the main body section is located, and a flow dividing guide wall is arranged on the upstream of the second channel body. According to the fish passing river channel device suitable for the shallow water return river reach, connection transition between a hydropower station and a downstream water return level can be achieved, a suitable river swimming zone with the flow speed meeting the fish river swimming requirement is formed in the shallow water return river reach, the fish upstream tracing requirement can be met when the hydropower station generates power or stops, the fish passing effect is guaranteed, and the ecological environment is protected.
本发明公开了一种适用于浅回水河段的过鱼河槽装置，包括水电站、鱼道和河槽，水电站包括主体段，水电站的下游设置有下游回水位，鱼道设置在水电站的一侧，鱼道包括鱼道进口、鱼道槽身和鱼道出口，河槽设置在鱼道进口与下游回水位之间，河槽包括第一槽道和第二槽道，第一槽道设置在主体段所在的一侧，第二槽道的上游设置有分流导墙。本发明的一种适用于浅回水河段的过鱼河槽装置，能够在水电站与下游回水位之间衔接过渡，在浅回水河段形成流速满足鱼类河游要求的适宜河游带，在水电站发电或停机时均能满足鱼类上溯需求，保证过鱼效果，利于保护生态环境。
