FIELD: hydraulic engineering.
SUBSTANCE: invention relates to hydraulic works designed to protect young fish from getting into diversion facilities. Proposed device contains fish retaining shield installed in water channel in tiers in depth of water channel with displacement of each higher tier to side of water intake channel, perforated air duct made in form of guides installed across water channel before shield on bottom of water channel, and trash-and-fish trough connected with fish outlet and arranged in upper part of shield parallel to air duct. Guides are made in form of flat plates rigidly installed at angle to flow in intake channel. Each plate is provided with horizontal axle in its upper part on which additional plate is secured from side of water intake channel for turning. Lower end face end of additional plate is provided with radial baffle whose surface has perforation holes. End face part of additional plates is provided with sector stopper from side of fish outlet, horizontal axles of plates being connected with drive. Additional plates can be perforated.
EFFECT: provision of retaining and bringing young fish out of the limits of influence of diversion facility.
