FIELD: energy.
SUBSTANCE: group of inventions relates to hydraulic power engineering and can be used for obtaining electric energy from hydraulic flows, including at low speed of water movement. In version of single unit device comprises storage water vessel filled with flow, accelerating device, turbine installed in vessel and connected via reduction gear with generator. Acceleration device is represented by rotary vane flow breaker connected by pull rod with float water level controller in vessel. When incoming water reaches specified level controller by means of pull rod connected with spring-loaded thrust, releases for movement switch blade and portion of water in the form of hydraulic pulse is transmitted on to turbine. Water level falls, controller releases thrust from tension which under spring action returns to initial position, stopping blade of turned flow switch for creating water reserve. In version of several modular devices installed in flow, their turbines are integrated with common shaft and connected via multiplexer to electric generator, and their float water level controllers in vessels are installed at different levels, which provides their series connection.
EFFECT: higher efficiency of damless HPS.
