UNDERWATER TIDAL POWER PLANT Russian patent published in 2016 - IPC F03B13/26 F03B17/06 

FIELD: energy.

SUBSTANCE: invention relates to hydraulic power engineering, in particular, to devices generating electric energy due to sea wave energy conversion, formed during tidal effects. Underwater tidal power plant comprises generator 1, consisting of hydraulic turbine and generator arranged in a sealed housing and kinematically connected with hydraulic turbine, frequency converter 6, through which generator 1 is connected to external power system and control system. Hydraulic turbine is made of blade type, and generator with excitation from permanent magnets. Generator 1 is installed in metal cylindrical frame 2, to the upper part of which are connected hollow tank 3 for holding frame 2 in underwater buried position. To the lower part of frame 2 are attached ropes 4, by one end connected with carcass 2, and the other with fixing units 5, lowering to sea bottom. Converter 6 is arranged on the shore and is connected to hydrogenerator 1 by means of electric cable 7. At the ends of frame 2 there are conical device to make water flow inlet confuser 8, and at outlet-diffuser 9.

EFFECT: lower construction costs, higher efficiency and reduced weight and dimensions of the power plant.
