HYDROPOWER INSTALLATION Russian patent published in 2009 - IPC F03B3/04 F03B17/06 F03B13/10 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to structures of installations for energy conversion of water course of airflow into electrical power. Hydropower installation contains generator 1 and hydrodynamic drive 4, implemented in the form of two sequentially installed screws 7 and 8, implemented with rotation ability into side opposite and connected to generator 1 through conversion facility of rotational movement of two shafts into rotational movement of one shaft, implemented in the form of conic step-up gear 13, installed in inner body 6. Inner body 6 is affixed to external body 5 by means of two wicket gates 23 and 24, provided for spinning of water flow before its supplying to the back screw 8.

EFFECT: invention is directed to increasing of coefficient of efficiency of installation ensured by increasing of back screw coefficient of efficiency.
