Wave-power system and method for generating energy at constant rotational speed at variable significant wave heights and periods

摘要

A wave energy conversion system or device is provided which includes a hull that serves as a float, moving up and down with incoming waves. The power take-off system contained within the hull comprises a longitudinal main rotary shaft upon which a series different diameter sets of dual same-diameter pinions interact with the main rotary shaft through their corresponding freewheels. This interaction only allows the main rotary shaft to rotate in only one direction. A fork-like rod system member that is either fixed directly to a base on the seabed or to a supporting underwater taut moored floating platform. This fork-like rod system member has an alternate rod in permanent contact with each pinion (two rods per each set of dual same-diameter pinions). The device also is capable of self-adjusting its mechanical properties and orientation to take into account the predominant wave frequency and direction over a period of time in a practical way to provide continuous, or multiple level, tuning of the system and is self-orienting for maximum and minimum energy absorption depending on sea conditions.
