Is intended to be installed on a suction system of pumping stations with productivity up to 450 cubic meters. It allows to take water from open sources from a small depth, to prevent penetration of silt and mechanical impurities, to scare young fish, and is able to self-clean with water. It is protected from fish, which is confirmed by the State Agency of Fisheries of Ukraine.
It is a rotating gauze cylinder with a unit of check valves. The whole structure is fixed on three water-tight metal pontoons. The rotation of the cylinder is carried out due to the energy of water supplied through the rubber hose from the pumping station to the nozzle of the wheel of the hydro turbine, which through the gear unit and a pair of gears rotates the cylinder. The self-cleaning of the cylinder is carried out by water from the washing nozzles, which are provided with water from the pumping station with a pressure of not less than 3 bar. The design involves adjusting the depth of immersion of the cylinder depending on the depth of the reservoir.
