Abstract:
An installation for power generation by ocean waves, the installation comprising:a main shaft; a flywheel mounted to the main shaft; a generator driven by the flywheel; at least one strength enlargement mechanism for rotationally driving the main shaft, the flywheel, and the generator; wherein each of the at least one strength enlargement mechanism comprises: a floater floating on a sea surface; a weight mounted on the floater; a lever having a first end connected to the weight and a second end hinged to a pivot central shaft; a ratchet wheel connected to the main shaft and freely rotating in a first direction; a chain having a first end and a second end; wherein the first end is connected to the lever and the second end is connected to the lever via a tension spring; wherein the tension spring fixes adjacent to the pivot central shaft such that the chain goes around the ratchet wheel; wherein said ratchet wheel is mounted in a way such that when the floater is pushed upwards by the wave, the second end of the chain is pulled back by the tension spring with the engaged ratchet wheel being rotated in the free rotating first direction; and wherein, when the floater is pulled downwards by the wave, the first end of the chain is pulled down by the lever with the engaged ratchet wheel, the main shaft and the flywheel being rotated in a second direction.
