FIELD: power engineering.
SUBSTANCE: device submerged into river along flow motion comprises working element in the form of continuous flexible chain. It covers wheel arranged with groove of specified chain laying and engagement to it and rigidly joined to power take-off shaft. And also blades that represent parachutes connected to continuous flexible chain and arranged with the possibility of opening under pressure of medium flow and folding in case of reverse flow. Continuous flexible chain is made of hingedly joined elements, part of which is connected to parachutes or is arranged in the form of parachutes. Wheel represents a power take-off shaft or electric or hydraulic machine inbuilt into this shaft, two hoops spaced at the distance from each other along axis of power take-off shaft, from which spikes radially come out in plane of wheel rotation, with every of which guide arcs are joined at a specified angle, being covered with hoop to form groove of triangular profile between hoops and locking chain link hinged joints as chain moves along groove trajectory.
EFFECT: invention provides for improvement of operational characteristics by provision of guaranteed engagement of wheel with chain with parachutes.
