HYDROPOWER STATION FOR THE PRODUCTION OF ELECTRICAL ENERGY BY SHALLOW RIVERS Russian patent published in 2021 - IPC F03B17/06 

FIELD: hydropower stations.

SUBSTANCE: invention relates to a hydropower station for the production of electrical energy by shallow rivers. Station 1 contains a hydraulic motor, including an axial-type blade propeller, installed in a horizontal position towards the water flow with the possibility of transferring rotation to the rotor of an electric generator 7. Station 1 is equipped with a structure located in a pit 2 at the edge of the bank of a shallow river 4 in the open water surface and including input and output water pipelines 5 and 8, butterfly valves, protective nets and technological compartment 6. Water pipelines 5 and 8 are located between themselves at an angle below the level of the river bottom 4. There is an electric generator 7 in compartment 6. Outlet water pipe 8 is directed into the river along the flow, and there is a suction pipe 9 at its end, which passes the upper layer of the water flow. The hydraulic motor is located by means of flange connections between the water lines 5 and 8 with the possibility of overlapping them when performing maintenance on the engine with disc valves. Protective nets are installed at the ends of water pipelines 5 and 8.

EFFECT: invention is aimed at ensuring year-round continuous operation of hydropowe stations using energy of shallow rivers.
