Abstract:
A device for coupling to an electrical power generator for generating electrical power from waves of a body of water, said device comprising:a base having upper and lower sides and front and back sides;a gate adapted for moving in response to the waves exerting pressure thereagainst, said gate having front and back surfaces, top and bottom ends, and a pair of lateral sides extending between said top and bottom ends;said bottom end of said gate being pivotally coupled to said base, said gate pivoting in first and second directions;a pushrod having proximal and distal ends and a longitudinal axis extending therebetween, said proximal end of said pushrod being pivotally coupled to said gate, said distal end of said pushrod being adapted for coupling to the electrical power generator;a ramp extending along a bottom of a body of water at an acute angle from a horizontal plane, said ramp having front and back ends and a top surface extending between said front and back ends, said base being positionable along said ramp between said front and back ends of said ramp;wherein said ramp has a threaded shaft rotatably extending between said front and back ends of said ramp and spaced apart from said top surface of said ramp, said lower side of said base having a drive flange extending downwardly therefrom, said drive flange having a threaded aperture therethrough, said threaded shaft being threadedly inserted in said threaded aperture of said drive flange of said base, wherein rotation of said threaded shaft in one direction moves said base along said ramp towards said front end of said ramp, rotation of said threaded shaft in another direction moving said base along said ramp towards said back end of said ramp; anda float switch extending from said back side of said base, said float switch comprising a buoyant portion coupled to an arm being extended from a switch, said motor turning said threaded shaft to move said base towards said back end of said ramp when said arm goes above a predetermined angle, said motor turning said threaded shaft to move said base towards said front end of said ramp when said arm goes below a predetermined angle.
