Abstract
A wave responsive generator comprises a buoyant float having an outer fixed shaft downwardly depending from the float with an inner rotatable drive shaft movably mounted within the outer shaft. At the lower most portion of the shaft opposite the float is a turbine affixed to the inner drive shaft opposite the float. A plurality of reversible vanes are movably mounted on the turbine for transmitting rotational energy to the inner drive shaft responsive to either upward or downward motion of the shaft responsive to wave action on the float. An electric generator or alternator is mounted on the float and cooperates with the inner rotatable shaft to produce an electric current responsive to the rotation of the inner shaft.
Claims5
A free floating wave responsive generator comprising:
- a. a buoyant float which freely bobs up and down responsive to the adjacent wave action during operation;
- b. an outer fixed shaft depending downwardly from said float;
- c. an inner drive shaft depending downwardly from and being rotatably mounted within said outer shaft to said float;
- d. a turbine affixed to said drive shaft opposite said float;
- e. a plurality of variable pitch vanes movably mounted on said turbine, said vanes transmitting rotational energy to said drive shaft responsive to upward and downward wave action on said float each of said vanes comprising a leading edge and a trailing edge, the area of the trailing edge being greater than the area of the leading edge, with fluid pressure acting generally vertically upon the vanes producing the variance of vane pitch responsive to the change of vertical direction of the float so that the drive shaft is rotated during both upward and downward movement of the float;
- f. electric generator means cooperatively connected to said inner drive shaft for producing an electrical current responsive to the rotation of said drive shaft;
- and
- g. a rotatable hub affixed to said drive shaft rotating freely with respect to the outer shaft at the lowermost portion thereof with said plurality of vanes attached to said hub, each of said vanes being movable between variable pitch positions responsive to fluid pressure thereon, the hub defining the travel limit of the vanes in each direction and a plurality of vane shafts radiating from the hub, each shaft supporting one of the vanes.
