Abstract
The power apparatus includes a plurality of paddle wheels arranged in tandem and intended to be positioned generally transverse to the direction of movement of water at the surface of a body of water, each of the paddle wheels having a plurality of cylindrically curved blades which are concave on the blade face to be engaged and pushed by the water. Belt-like means mechanically couple the paddle wheels together to a power utilization device.
Claims22
Apparatus for deriving power from the movement of water at the surface of a body of water comprising
- a plurality of paddle wheels arranged in tandem and mutually parallel and to be positioned generally transverse to the direction of water movement,
- each of said paddle wheels having a plurality of cylindrically curved blades,
- a supporting means for supporting said paddle wheels for engagement by the lowermost blades with the water,
- said supporting means including a plurality of floats operable to maintain the desired elevation of said paddle wheels by flotation of the entire apparatus,
- said floats comprising discrete flotation tanks,
- said supporting means comprising a plurality of separate support frames for said paddle wheels,
- each of said support frames having discrete flotation tanks,
- means for interconnecting said support frames to provide the tandem arrangement of said paddle wheels wherein said paddle wheels are arranged with substantially parallel axes,
- the curvature of said blades being concave on the blade face to be engaged and pushed by the water,
- and belt-like means mechanically coupling said paddle wheels together and coupling said paddle wheels to a power utilization device,
- said separate support frames being interconnected by articulated interconnections to permit at least limited relative angular movement between adjacent frames at the interconnections while the paddle wheels on adjacent frames are interconnected by said belt-like means.
