An improved hydroelectric system provides automatic adjustment for both tidal (reversing) and river (one way) type flow. A plurality of parallel, axial flow auger-type impellors are mounted in a horizontal plane on a floating, inverted-dry-dock type vessel that has an upper deck mounting hydroelectric generators. The vessel has no bottom beneath the impellors but has parallel with them on each side a tank for buoyancy and level and flow control. Over and under the impellors are pivoting deflectors that direct flow onto the impellors and automatically reverse and rest against appropriate bumper stops when the flow reverses, from one open end to the other open end of the vessel.

A system for hydroelectric generation of power from flow of water along an auger-type drive for generator equipment mounted adjacent thereto, characterized by: a vessel in the form of an inverted drydock and having a deck and longitudinal parallel-spaced first and second sidewalls defining open ends

A system for hydroelectric generation of power from flow of water along an auger-type drive for generator equipment mounted adjacent thereto, characterized by: a vessel in the form of an inverted drydock and having a deck and longitudinal parallel-spaced first and second sidewalls defining open ends and bottom, means for mounting said auger-type drive on said vessel beneath said deck and between said sidewalls, means for directing flow of water between said sidewalls for increasing said flow of water onto said auger-type drive, including a plurality of deflectors, respective deflectors of said plurality of deflectors mounted above and respective of said deflectors mounted below said auger-type drive, each deflector extending from the first sidewall to the second sidewall and pivotally mounted to the sidewalls about an axis transverse to said sidewalls, causing it to rotate in a first direction in response to tidal flow of water past it in said first direction and in a second direction in response to tidal flow past it in said second direction; each deflector having an open “V”-shape with first and second arms and with said axis being along the apex of the open “V”-shape; each of said deflectors mounted above the auger-type drive having said apex downward and each of said deflectors mounted below the auger-type drive having said apex upward, bumper stop means on said vessel for limiting pivoting of the deflectors so that a first arm of the open “V”-shape will respectively lie adjacent to the auger-type drive with the flow of water in said first direction therealong and so that a second arm of the open “V”-shape will respectively lie adjacent to the auger-type drive with the flow of water in said second direction therealong.
