Embodiment Construction

[0013] In order to facilitate the understanding and implementation of the present invention, the preferred embodiments of the present invention will be further described in conjunction with the accompanying drawings.

[0014] Such as figure 1 with figure 2 As shown, the present invention includes a mobile car pool room 1, a track 2, a track beam 3, and a lifting traction device 4. The mobile car pool room 1 is arranged on the track 2, and the track 2 is fixedly installed on the track beam 3, and the traction device 4 is used for lifting To drive the mobile car pool room 1 to move back and forth along the track 2, the track beam 3 can be set on the downstream dam slope of the dam or the bank slope beside the dam according to the specific conditions of the migratory fish, so that one end of the track 2 connects to the downstream river. , The other end is connected to the upstream reservoir; the mobile trolley pool room 1 includes a fish collecting pond room 7 and a fish room inlet...

Abstract

The invention relates to a lifting fish channel structure, and belongs to the technical field of fish channel building designs. The lifting fish channel structure comprises a mobile trolley pond room,a track, a track beam and a lifting traction device. The mobile trolley pond room is arranged on the track, the track is fixedly mounted on the track beam, and the lifting traction device is used fordriving the mobile trolley pond room to make a reciprocating motion along the track. The track beam is arranged on the downstream dam slope of a dam or on the bank slope on the side of the dam, so that one end of the track is connected with the downstream river channel and the other end of the track is connected with an upstream reservoir. The mobile trolley pond room consists of a fish gatheringpond room and an inlet section of a fish room. The fish gathering pond room is connected to the inlet section of the fish room through an entrance door. An exit door is arranged on the fish gatheringpond room. A water supply pipe communicates with the fish gathering pond room. The lifting fish channel structure has advantages of simple structure, convenient arrangement, and low project investment. Meanwhile the difficulty of fish migration is reduced by using artificial means to help fish migration, and the lifting fish channel structure is especially suitable for the condition that the fishchannel is difficult to build in a water conservancy and hydropower project with high dam height.

Description

Technical field [0001] The invention relates to a lifting fishway structure, belonging to the technical field of fishway building design for water conservancy and hydropower projects. Background technique [0002] Due to the construction of water conservancy and hydropower projects, the natural river channel was cut off, blocking the natural migration channel of fish. As a remedial measure, fish passage is a kind of fish-passing structure set up at the barrage dam to communicate fish migration channels. [0003] According to "Guidelines for Fishway Design of Water Conservancy and Hydropower Engineering" SL609, conventional fishway structures include ecological, clapboard, trough, and special structure types. The above fish channel structures are all continuous water channels, the fish channel is longer, the structure is more complicated, and the fish channel layout requires a larger site. For fish with small individuals, low migratory ability, and low flow capacity, high requirem...
