DEVICE TO PREVENT GETTING OF YONG FISH INTO WATER INTAKES

摘要

devices for taking water from ground sources with protection of young fish. SUBSTANCE: proposed three-dimensional filtering cassette is essentially metal rectangular frame with slots on inner side in which water- permeable filtering plastic pipes are fitted. Cassette is installed in guide slotted structure of inlet ports of sunk water intake head. To provide tight fitting of filtering plastic pipes, dimensions of metal rectangular frame should be divisible by diameter of water-permeable filtering plastic pipes. Water- permeable filtering plastic pipes can be installed in three- dimensional filtering cassette vertically or horizontally, in one or several rows. EFFECT: improved protection of young fish. 4 cl, 3 dwg
