FIELD: power industry.
SUBSTANCE: technical solution consists in artificial narrowing by a ground bridge of a river bed and creating concentration of kinetic energy of the water flow and in further using a vertical bucket longline hydroturbine in work. The hydroelectric power plant consists of a hydroturbine, generator, transformer, auxiliary and other equipment. Artificial narrowing of the river bed is achieved by a ground jumper and a water intake (1) in the form of a truncated cone or a prism shape . A turbine pipeline is connected to the water intake (1) with intermediate concentrators (2) in the form of a truncated cone shape. The water flow, passing through the turbine pipeline with concentrators (2), enters the distributors and further into the nozzles of the hydroturbine through the outlets and has the velocity and kinetic energy necessary to ensure the operation of the vertical bucket longline hydroturbine of the installed capacity. To prevent the entry of floating waste, wood and other wastes into the turbine pipeline, protective barriers (3) are installed in front of the water intake of the turbine pipeline in the form of gratings, grids, etc. preventing the waste penetration into the turbine pipeline. To ensure the fish passage to spawn, a bypass (4) with basis of spandrel is installed parallel to the turbine pipeline, through which the fish during the spawning season passes through the HPP. A fish-farm can be placed on the bypass. The inlet of the bypass is covered by shields or other devices, the normal position of which is closed, and they are opened only for the period of the fish passage during spawning.
EFFECT: increasing the speed of water flow ensures the operation of a HPP year-round, there will be no negative impact on the environment.
