METHOD OF PASSAGE OF BABY FISHES THROUGH HYDRO-ELECTRIC STATION BY DOWN-STREAM MIGRATION

摘要

1. A method of juvenile fish passes through the hydraulic assembly with downstream migration, comprising: forming along the entire length rybohodnogo managed path of water flow, depending on the difference between the upper and lower levels befov generated in each cell by feeding the fish ladder Water Flow strueobrazuyuschie nozzles located along the perimeters vplyvnyh apertures or holes directly into vplyvnyh, or autonomous channels formed in the separation walls and directed towards the upstream, a subsequent shaping step allelic or at an angle to the axis vplyvnogo hole rows flooded parallel hydraulic jets, the jets may be pre-twisted, and creating at the joint interaction of these series of jets of hydraulic resistance of the main flow, the incoming on rybohodnomu path through the chambers fish pass from the upstream, thereby enabling conditions for the passage of a fish through vplyvnoe hole, characterized in that the controlled aqueous stream involves moving fry that approached and accumulated in front of the dam erhnem reach of hydro and direct it in the path rybohodny fish ladder, and then outputs the juvenile fish to a safe place of the downstream hydroelectric. ! 2. A method according to claim 1, characterized in that the water flow rate managed is determined by the following formula: ,! wherein VPOTOKA - average speed managed aqueous flow, m / sec; ! g - acceleration due to gravity in m / s2; ! H - pressure value attributable to the divider wall, m; ! φ - dimensionless coefficient determined empirically; ! V0 - expiration of the initial rate of hydraulic jets from the jet
