  • Natural-frequency adjusting mechanism for wave-power generator
    Patent number: 9322388
    Abstract: 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 includes a weight that is installed in a floating body via a spring and that linearly reciprocates in response to a fluctuation of a water surface and a generator that generates power by being driven based on the linear reciprocating motion of the weight. An additional-mass body for adding a mass to the mass of the weight is further included.
    Type: Grant
