Abstract
A wave responsive electrical generator device having a buoyant member connected to an anchor by a tether line member, the line member passing through a sheave mounted within the buoyant member and descending to a counterweight, whereby vertical motion of the buoyant member results in rotation of the sheave, which in turn operates hydraulic cylinders to deliver hydraulic fluid under pressure to an hydraulic motor, which drives an electrical generator, wherein the line member is a plurality of belts mechanically interlocking with the sheave.
Claims20
A wave responsive electrical generator device comprising:
- an anchor member;
- a buoyant member comprising a rotatable main drive sheave, an hydraulic motor operated by said main drive sheave, an electric generator operated by said hydraulic motor, and an hydraulic reservoir containing hydraulic fluid;
- a counterweight member;
- and
- a line member extending from said anchor member through said buoyant member and to said counterweight member, said line member being received by said main drive sheave and comprising a plurality of belts mounted onto said main drive sheave;
- whereby movement of said line member resulting from up and down movement of said buoyant member relative to said anchor member causes rotation of said main drive sheave, operation of said hydraulic motor and operation of said electrical generator to produce electricity.
A wave responsive electrical generator device comprising:
- an anchor member;
- a buoyant member comprising a rotatable main drive sheave, hydraulic cylinders connected to said main drive sheave by a sheave crank arm, said hydraulic cylinders delivering hydraulic fluid through hydraulic conduits to a plurality of gas pressurized hydraulic fluid accumulator tanks, said accumulator tanks delivering hydraulic fluid to an hydraulic motor, said hydraulic motor driving an electric generator;
- said buoyant member further comprising a disk-shaped upper body and a lower body, the width of the lower body being less than the width of the upper body;
- a counterweight member;
- a line member extending from said anchor member through said buoyant member and to said counterweight member, said line member being received around and mechanically interlocking with said main drive sheave and comprising a plurality of belts mounted onto said main drive sheave, whereby movement of said line member resulting from up and down movement of said buoyant member relative to said anchor member causes rotation of said main drive sheave such that said hydraulic cylinders deliver hydraulic fluid to said hydraulic motor, which in turn drives said electric generator to produce electricity;
- and
- a line encircling assembly connecting said counterweight member to said line member between said anchor member and said buoyant member, said line encircling assembly allowing vertical movement of said counterweight along said line member between said anchor member and said buoyant member in response to vertical movement of said buoyant member.
