Abstract:
1. A wave powered electrical generator, comprising: A first floating unit adapted to float in water and accommodate a power generator therein; a second floating unit adapted to float in the water in the vicinity of the first floating unit; a spring line, one end of which being attached to the second floating unit and the other end of which being operatively connected to the power generator, such that a relative movement between the first unit and the second floating unit causes the spring line to rotate a shaft of the generator and generates electrical power, wherein the first floating unit accommodates, therein, an outer pulley supported by an inner wall of the first floating unit and to which the spring is wound, such that the outer pulley is rotated by a movement of the spring line, a spool supported by the inner wall of the first floating unit for retracting and extending the spring line, an inner pulley, a first gearbox mechanically connected to the inner pulley, a belt extending between the outer pulley and the inner pulley, such that a gear in the gearbox is rotated as the outer pulley rotates, and a wheel rotatably supported inside the first floating unit and having an external gear in engagement with the gear in the gearbox, wherein, the generator is rotated by rotation of the wheel.
