FISH-PROTECTING JET GENERATOR Russian patent published in 2010 - IPC E02B8/00

Abstract RU 2386746 C2

FIELD: construction.

SUBSTANCE: invention is related to hydraulic engineering and may be used for prevention of young fishes getting into water intake structures. Jet generator comprises discharge branch pipe with nozzles. The main discharge nozzle is arranged inside additional water intake nozzle, to which head is connected coaxially to nozzles, which generates flat water jet. Additional nozzle is arranged with uneven cross section that narrows in direction of its cross section, which is most remote from water intake holes used to connect it to water reservoir.
