FIELD: hydraulic building, particularly fish passes permitting fish passage through support structures to fish hatchery and growth areas.
SUBSTANCE: fish pass comprises fish-passing canal made as gutter and connecting upper and lower hydrosystem pools. Fish pass also has transversal partitions made of flexible members and fastened to fish-passing canal by lower ends thereof. The transversal partitions are arranged along fish-passing canal and create working chambers. Swimming-in orifices are made in each transversal partition. Transversal partitions are formed as flexible plates and provided with roughened members and stabilizing means. Roughened members are located from head flexible plate sides in upper parts thereof. One end of stabilizing means is fastened to upper part of free transversal partition sides and made as elastic web having width equal to that of transversal partition.
EFFECT: simplified fish-pass structure and increased efficiency of fish passage control.
