POWER-GENERATING DEVICE Russian patent published in 2012 - IPC F03B13/10 

FIELD: power engineering.

SUBSTANCE: in a power-generating device a hydraulic turbine and a synchronous power generator (3) make an assembly moving jointly with a rotor (7) of the generator. The generator rotor (7) comprises poles with permanent magnets (1). The hydraulic turbine is arranged of propeller type or Kaplan type. Hydraulic turbine blades (11) are either fixed as capable of adjustment in process of installation or are arranged as controllable by means of mechanisms of hydraulic or electric systems. The central shaft of the device is installed with the possibility to adjust its position in longitudinal and radial directions relative to the specified assembly. The generator rotor (7) is sealed and fully submerged into water, allowing for presence of water in a gap (10) between the rotor and stator of the power generator. The device additionally comprises external electronic, electromechanical or hydraulic equipment for control of electric voltage and frequency.

EFFECT: invention makes it possible to simplify maintenance of a device and reduce its frequency.
