Floating wave powered pump
Patent
·
OSTI ID:6788928
A hydraulic power source for harnessing energy generated by the wave motion of a body of water is described. A primary or main float has a plurality of secondary or satellite floats spaced outwardly therefrom. The secondary floats are each attached to one end of a plurality of lever arms, the other ends thereof being attached to a plurality of rotatable shafts carried by the primary float so that up/down motion of the lever arms is translated into rotational motion of the shafts. When placed upon a body of water, the wave motion causes the secondary floats to be displaced upwardly or downwardly relative to the primary float. The motion of the secondary floats is translated by the generally vertical movement of the lever arms to the shafts to rotate the shafts. The rotational motion of the shafts is translated into linear motion within the primary float by means of interacting cam surfaces which activate pistons of linear pumps. The linear motion of the pistons within the pumps is used to pump a hydraulic fluid from a reservoir into pressure accumulators. The pressure stored within the pressure accumulators may be selectively tapped as a source of power.
