FIELD: agriculture.
SUBSTANCE: complex fish protection device includes at least one flow developer with nozzles that is positioned horizontally, or vertically, or horizontally and vertically at the same time. Each separate flow developer can be installed on any horizon and in any section line of a water source. The number of nozzle rows in each separate flow developer, and the number of nozzles in each individual row can be from 1 or more and vary within the same device. The installation angle and the nozzle diameter of each individual nozzle can be any and vary within the same device. The device includes an electric screen consisting of 1 or more cassettes, on which electric current is supplied, forming an electric field. Each individual electric screen cassette is represented by a set of plates, or bars, or rods, or a mesh fabric, made of electrically conductive material, which may have the vertical, horizontal or sloping arrangement, the rectilinear, curvilinear, or zigzag shape. The number of plates, or bars, or rods in each individual cassette of the electric screen can be from 1 or more and vary within the same device. The installation pitch and the inclination angle of the plates, rods or rods, the dimensions of the mesh fabric cells in each individual cassette of the electric screen can be any and vary within the same device. Each individual cassette of the electric screen can be installed on any horizon and in any section line of the water source. Wherein the cathode can be represented by one or more cassettes of the electric screen, and all the remaining or some of the remaining cassettes of the electric screen become anodes. Alternatively, each subsequent or several subsequent cassettes of the electric screen, or through one cassette or group of cassettes of an electric screen, or in staggered order, can become a cathode.
EFFECT: improving the operation efficiency of the device, reducing the probability of fish and debris entering the water intake, creating optimal hydraulic conditions for the transit flow, ensuring the removal of fish from the water intake area, reducing the probability of bigger fish entering the water intake.
