HYDRAULIC DRIVER Russian patent published in 2009 - IPC F03B13/10 

FIELD: mechanical engineering.

SUBSTANCE: invention is provided for energy conversion running medium of small volumes into electrical. Hydraulic drive contains body 1 with installed in it impeller 2, passing by means of flexible shaft 7"б" rotational moment to generator 9, located on the beach. Hydraulic drive is outfitted by additional bodies 1 with installed in each of them flexible shaft 1a impeller 2 of hydraulic turbine and holders 6a and 6"б". By means of holders 6a and 6"б" flexible shafts 7 of impellers 2 are connected to each other, herewith bodies 1 are installed on supports 8 on bottom of waterway. Impellers 2 of hydraulic turbines are implemented in the form of screws.

EFFECT: invention is directed to providing of ability of energy extraction from running medium of small volume and slow flow velocity, that is from narrow rivers, streams, aryks, and also increasing of drive power ensured by series connection of similar devices.
