FIELD: construction.
SUBSTANCE: complex fish protection device of barrier-filtering action comprises a water-permeable screen. The screen comprises filtering meshy and/or louver elements. Elements are combined into horizontal lines in rows and along the vertical line into modules. Besides, the device may comprise sections of electrodes. Each separate filtering element is isolated from others with the help of a dielectric material and is made of an electroconductive material or a material that does not conduct current. The number of rows of filtering elements and modules makes from 1 and more. Each row comprises meshy or louver elements. Each module comprises meshy or louver elements, or meshy and louver elements simultaneously. The number of filtering elements in one row and in one module makes from 1 and more. The size of the cell in the meshy cloth of the meshy element makes from 1 mm and more. The clear space between louver plates of the louver element makes from 10 mm and more. Along the horizontal line the rows of meshy and louver elements may alternate and be arranged in any sequence. The size of the cell in the meshy cloth of the meshy elements and the clear space between louver plates of the louver elements in different rows and modules may be different. Pulse current is supplied to all or separate filtering elements, creating electric field around the water-permeable screen.
EFFECT: increased efficiency of device functioning.
