Comprehensive fish concentrated transportation platform and method for preventing hydropower station from stopping fish from sailing upstream

Abstract

The invention discloses a comprehensive fish concentrated transportation platform and a method for preventing a hydropower station from stopping fish from sailing upstream. The method comprises the following steps: according to the phenomena that tail water drainage of the hydropower station has attraction to the sailing-upstream fish in the river sections under a dam, and the tail water with higher flow rate forms a barrier to prevent fish from sailing upstream, a fish attracting passage is newly built at the downstream area of the forefront position, that the fish sails upstream to reach, ofthe downstream of the tail water; related fish attracting measures, observation apparatuses and lifting transferring facilities are additionally arranged in the passage to realize the purposes of attracting, observing and transferring fish under the dam; and then, the fish is transferred to a river sections of a reservoir area on the dam for release through an automobile, so that the obstructingaction to the sailing upstream of the fish under the dam from the dam is slowed down.

Description

technical field [0001] The invention discloses a comprehensive platform for collecting and transporting fish and a method for solving the problem that a hydropower station hinders fish from going up. Background technique [0002] The construction of hydropower projects, especially the construction of large-scale high-head power stations, inevitably destroys the connectivity of rivers, resulting in fragmentation of rivers, blocking fish migration channels and gene exchange, and fragmenting fish habitats. Therefore, the restoration of fish migration channels through the construction of fish passing facilities has important practical application value and practical significance for protecting fish biodiversity and reducing the impact of the project on fish. [0003] At present, there are two kinds of measures applied to the project in view of the blocking of fish migration channels: one is an indirect measure, which protects the population of affected fish through artificial br...
