ABSTRACT:
A fixed structure encloses a vertically spaced plurality of superimposed channels that are open at one end of the sea to receive deep sea waves approaching a shoreline. Each of the channels has an entrance ramp that slopes upwardly shorewardly to induce breaking of a wave at and over an apex of trailer service ramp that merges into a shorewardly downwardly sloping convergent conduit having fluid communication with a pressure chamber of the structure through a one-way valve controlled aperture at which the wave energy is concentrated. A portion of each ramp is overlain by a roof which may comprise the underside of a superimposed ramp of another channel. Each of the ramps is of upwardly convex configuration, transversely to the wave direction, and at opposite sides is provided with re-entrant scuppers for draining backwash from a receding wave. Wave focusing vanes or walls diverge seawardly from the open end of the fixed structure along an axis bisecting a submerged transverse wall member embedded on the sea floor, of a lens configuration for bending and focusing a given linear wave length into the convergent walls. Water is directed from the pressure chamber of the structure into energy recovery devices utilizing the kinetic, hydrostatic and pneumatic energy contained in the pressure chamber, which acts as an accumulator.
