FIELD: engines and pumps.
SUBSTANCE: invention is related to hydropower engineering, in particular, to power units actuated by flow of flowing medium, and may be used for transformation of flowing medium flow energy, for instance, of river flow, into electric energy. River hydraulic unit for utilisation of flowing medium flow comprises bearing frame with active turbine arranged in the form of infinite conveyor installed across flow of flowing medium and having two shafts embraced with flexible traction element with blades arranged at the angle to flow direction, sliding supports that interact with guides of bearing frame, on which electric generator is installed, being kinematically joined to one of infinite conveyor shafts. Hydraulic unit is equipped with additional flexible traction element embracing shafts installed along flow and transverse support elements that join together flexible traction elements. Sliding supports are installed on flexible traction elements. Blades are fixed on transverse support elements.
EFFECT: increased total working surface of blades affected by flow of flowing medium, reduced number of sliding joints and simplified design, which makes it possible to increase capacity of power unit.
