Abstract
A linearly translating set of aerofoil blades guided along rigid supporting columns that build up hydraulic energy by drawing hydraulic working liquid from a low pressure reservoir and pushing it into a high pressure accumulator through pistons and hydraulic cylinders. The functioning of an intelligent controller senses the motion of the aerofoil blades and controls orientation with respect to the wind and the valves in the hydraulic circuit so that the aerofoil blades, irrespective of their forward or return motion, always draw liquid from the low pressure reservoir and push it into the high pressure accumulator is also described.
Claims14
A device for harnessing wind power using linear motion, the device comprising:
- reciprocating aerofoil blades that translate linearly converting wind energy into pressurized hydraulic working fluid that can be used for generating electrical energy or producing mechanical power;
- a reciprocating piston and hydraulic cylinder arrangement;
- and
- a hydraulic high pressure accumulator that stores hydraulic energy from the hydraulic working liquid being pushed into the high pressure accumulator,
- wherein the aerofoil blades drive the piston to build up hydraulic pressure in the accumulator through the piston and hydraulic cylinder arrangement.
A device for harnessing wind power using linear motion, the device comprising:
- a plurality of parallel reciprocating aerofoil blades that translate linearly in synchronization, converting wind energy into pressurized hydraulic working fluid that can be used for generating electrical energy or producing mechanical power;
- a reciprocating piston and hydraulic cylinder arrangement;
- wherein the aerofoil blades are pivotably connected to a linkage that drives the reciprocating piston inside the hydraulic cylinder;
- a hydraulic high pressure accumulator that stores hydraulic energy from the pressurized hydraulic working liquid being pushed into the high pressure accumulator;
- and
- a hydraulic control mechanism to ensure that the pressurized hydraulic working fluid is directed to a correct side of the hydraulic cylinder with respect to the piston;
- and a hydraulic low pressure accumulator that provides the working fluid to be pressurized.
