ELECTRIC FISH BARRIER OF DIRECTED ACTION Russian patent published in 2013 - IPC E02B8/08 A01K79/02 

FIELD: electricity.

SUBSTANCE: fish barrier includes an electronic control unit and a double-row system of electrodes divided into sections. Each row of electrodes combined into half-sections is arranged at the angle to an arriving flow. A section of electrodes comprises two half-sections, one half-section from each row of electrodes. In the first version, a cathode is in turns one of the electrode sections, anodes are all remaining sections of electrodes. In the second version, a cathode is in turns one of the electrode sections, anodes are all remaining sections of electrodes, not adjacent to the cathode one. The produced homogeneous cathode electric field creates a wide deterring zone, which aligns fish away from electrode sections and takes it away from the protected water intake.

EFFECT: improved characteristics of fish departure from a zone of fish barrier coverage due to reduced impact of arriving flow at fish in process of their exit from an electric field created by a device, and higher efficiency of device functioning.
