ABSTRACT:
An apparatus for generating rotary motion from rise and fall motion of waves includes an outer hollow sleeve, a float sealably attached across the upper end of the outer sleeve to define an interior cavity, prevent entry of water into the cavity and provide the outer sleeve with sufficient buoyancy to floatably follow up and down motion of waves, an inner hollow sleeve fitted telescopically within the outer sleeve, and an anchoring arrangement attached to the inner sleeve for restraining it from following up and down motion of waves with the outer sleeve and float. The outer sleeve will slidably move up and down relative to the inner sleeve as the outer sleeve and float floatably follow up and down motion of waves and correspondingly will draw a flow of water upwardly and force a flow of water downwardly through the inner sleeve. The apparatus also includes a single rotary motion-producing mechanism mounted within the inner sleeve intersecting and engaging the flow of water through the inner sleeve. The rotary mechanism includes a rotary shaft and a turbine rotor mounted on the shaft for rotation therewith. The rotor has a set of hinged blades being pivotally reversable in their deflected positions in response to change in direction of the flow of water upwardly and downwardly through the inner sleeve for continuously rotating the shaft in a single direction.
