FISH PROTECTING AGGREGATE OF WATER INTAKING STRUCTURE Russian patent published in 1994 - IPC

FIELD: hydraulic technology. SUBSTANCE: garbage and fish fry, incoming with stream of water into water intaking structure are delayed by small cell net type sheets and using local discretely placed in depth of water garbage and fish leading away baffles, formed by perforated sprays directing members, are fed to garbage passage. Net type sheets and perforated sprays directing members water transparency of which exceeds water transparency of net type sheets, are fixed with capability of turning on horizontal shafts and form cross-shaped sections in cross section. In case of fish fry concentration in zone of water intake decreases, sections are turning on horizontal shafts, forming filtering field from perforated members, that have bigger size of cells, than net type sheets. EFFECT: fish protecting aggregate of water intaking structures is used in hydraulic technology. 3 dwg
