UNIT FOR TIDAL FLOW ENERGY UTILISATION Russian patent published in 2015 - IPC E02B9/08 F03B13/12 

FIELD: power industry.

SUBSTANCE: invention refers to hydro power engineering. Device utilising tidal flow energy includes rotor 1 consisting of spiral vanes with segmented profile, attached by cross-beams to the shaft, and generator mounted on a platform and connected to the rotor. Lower end of rotor 1 shaft and generator connected to it are placed in a sealed capsule 2. Sealed capsule 2 rests on two bearing beams 4 with the help pf two pins 3 protruding from opposite sides of outer capsule surface and can rotate around horizontal axis perpendicular to the flow direction. Bearing beams 4 are attached to cylindrical cases 5, the ends of which are interconnected by braces 7 with segment-shaped cross-section turned with its convexity down and forming α angle to the horizon to produce lifting power directed towards the bottom.

EFFECT: simplified design, extended application range covering water areas of large-capacity navigation and ice cover.
