PURPOSE:To convert wave pressure energy into oil hydraulic pressure with simple constitution, by operating a bag member to be expanded and contracted with the pressure of a wave colliding against a movable plate. CONSTITUTION:If a wave collides with a movable plate 3 of a bag member 6 fixed by a fixed plate 2 to the side wall of a structural body 1, the bag member 6 connecting the fixed plate 2 to the movable plate 3 is extended and contracted by a pressure of the wave, and in accordance with this movement, a pressure increasing bag member 8 communicated to the bag member 6 through a hole of the fixed plate 2 is extended and contracted. Accordingly, a piston rod in a cylinder device performs reciprocating motion through a closing plate 9 with the conversion of wave pressure energy into oil pressure energy. In such way, power of the wave, being transmitted from the movable plate 3 to an operating device not by the mechanism but by the fluid, can permit a device to be formed in small size with simple constitution further with the improvement of energy conversion efficiency. |
