Patent ID: 7487637

Claim:
A hydraulic power plant for generating electrical energy by transforming hydraulic energy of a water flow by means of a hydraulic turbine ( 1 ) comprising at least a rotor ( 2 ), a generator ( 3 ) driven by the rotor ( 2 ) and a float ( 4 ) for the hydraulic turbine ( 1 ), wherein a) the hydraulic turbine ( 1 ) is anchored in a fixed position and the rotor ( 2 ) is aligned in the direction of flow of the water, b) the hydraulic turbine ( 1 ) is held in a floating state underneath the surface of the water, c) for this purpose the float ( 4 ) can be acted upon with a gaseous medium, including compressed air and if necessary, flooded with water, d. the rotor ( 2 ) is mounted on a rotor axle ( 7 ) aligned in the direction of flow of the water, e) the rotor blades ( 8 ) of the rotor ( 2 ) can be adjusted by means of an adjusting mechanism ( 9 ) in or opposite to the direction of flow and f) the rotor axle ( 7 ) is constructed as a hollow axle and forms the float ( 4 ).
