FIELD: hydraulic engineering.
SUBSTANCE: invention is aimed at preventing young fish from getting in diversion facility. Proposed device contains three-dimensional filtering cassette installed in guide of slot structure of intake port of submerged intake head of diversion facility consisting of metal rectangular frame with filtering plastic tubes tightly fitted in slots on inner side. Plastic tubes are made truncated along their generatrices on secant line of base of corresponding filtering plastic tube, chord of secant line of base of filtering plastic tubes is equal to or is non-equal to their outer diameter, and sizes of metal rectangular frame are multiple of said chord. Truncated filtering plastic tubes can be installed in metal rectangular frame in slots on inner side vertically or horizontally, being interconnected by hydraulically insulating material.
EFFECT: provision of effective protection of young fish from getting into diversion facility.
