Gate valve pipeline type fish passing facility

Abstract

The invention relates to a gate valve pipeline type fish passing facility. The gate valve pipeline type fish passing facility comprises a fish collecting cabin, a gate, a fish passing pipeline, a fishattracting structure, a water injecting pipeline and a discharge pipeline, the body type of the fish collecting cabin is small, fish passing is performed by adopting the pipelines, the pipelines canbe laid underground and on the ground, land occupation is less, the terrain adaptability is high, nearly no terrain restrictions occurs, and engineering site selection and arrangement are facilitated.A long-distance gentle slope channel is not required, a cumbersome water gate and start-stop equipment are not required, complex structural design and expensive lifting equipment are not required, and the engineering cost is reduced. The pipeline water pass fracture surface is small, the flow speed is low, and the flow is small; and fish attracting and fish concentrating are realized through thefish collecting cabin, concentrated fish passing is carried out by cabins and times, continuous discharge required by continuous fish attracting is avoided, and the water consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of fish passing facilities, in particular to a gate valve pipeline type fish passing facility. Background technique [0002] In order to meet the needs of flood control, power generation, water supply and navigation, people often build water conservancy facilities such as dams and power stations in rivers. These facilities destroy the connectivity of the original river, fragment the ecological environment of the river, block the migration channels of fish and other aquatic animals and plants in the river, cause the loss or change of habitat, and lead to the reduction or even extinction of fish. [0003] Under the general environment of vigorously advocating the construction of ecological civilization, fish passing facilities such as fishways, fish locks and fish lifts are not only a water conservancy project, but also a compensatory project for the ecological benefit of the people. , Restoring the original ...

Problems solved by technology

[0005] In terms of building fish passing facilities, the main forms at home and abroad mainly include imitating natural bypass fishways, technical fishways, fish gates, fish lifts, fish collection and transportation systems, etc., but the above fish passing facilities either occupy a large area , either the project cost is high, or the water consumption is high
