NATURAL VIBRATION ADJUSTMENT MECHANISM OF WAVE POWER GENERATOR

摘要

Provided is a wave-power generator capable of adjusting a natural period (natural frequency) in response to a changing wave period. The wave-power generator (1) includes a weight (3) that is installed in a floating body (2) via a spring (4) and that linearly reciprocates in response to a fluctuation of a water surface (7) and a generator (8) that generates power by being driven based on the linear reciprocating motion of the weight (3). An additional-mass body (6) for adding a mass to the mass of the weight (3) is further included.
