FIELD: power industry.SUBSTANCE: invention relates to hydropower engineering, namely to hydroelectric power plants. A run-of-river hydroelectric power plant 2 is installed on a basement 26 and contains several rigid, water-tight housings 6 with an elliptic cross section fitted with turbine modules 8 arranged with a possibility of transmission of rotation from shafts 13 enclosed by a ring 27, turbines 12 through free-wheeling clutches 14 to the common shaft 15 passing through an onshore well 21 with the ground river water circulating in it through a reducer 16 to the rotor shaft of an electric generator 17 installed on the shore 3. In each turbine module 8 the plane of rotation of the turbine 12 blades is inclined at an angle to the longitudinal axis of the flow 1, in the zone of the hub 18 of the turbine 12 to which blades are fastened. On a guiding lattice 11 located upstream the turbine 12 a cone-shaped body 25 is installed with the top oriented upstream. From the back side on the hub 18 of the turbine 12 a hemispherical body 19 is installed. Upstream and downstream the turbine module 8 a shutoff device 7 is installed.EFFECT: invention is aimed at providing of extraction of the maximum possible part of kinetic energy of water, which freely flows in the river, for its conversion into electric power.21 cl, 9 dwg |
