Thus, the pressure receiving plate 5 reciprocates in a single oscillation like a pendulum in accordance with the wave force around the mounting shaft 7 via the support rod 6. This movement is transmitted to the piston device 2 through the piston connection fitting 9 and serves as a drive source that converts the pressure into a positive pressure and a negative pressure.

を繰り返し行う事となる。The above pressure activates the backflow prevention valves 13a and 13b attached to the suction side and the discharge side of the pump device 3, respectively. When the wave rises, the pressure becomes a positive pressure, the suction side backflow prevention valve 13a is closed, and the discharge is performed. Side check valve 13b opens,
Seawater is discharged from the discharge port 15 of the pump shield 3. When the wave descends, the pressure becomes negative, the operations of the check valves 13a and 13b on the suction side and the discharge side are reversed, and seawater is sucked from the suction port 14 of the pump device 3. Since this motion is transmitted to the wave power absorbing device 1, the piston device 2, and the pump device 3 in accordance with the motion of the wave, the seawater repeatedly sucks and discharges.

The rear surface has an opening to allow the air to pass through . In addition, a screen 20 is attached to the widening portion on the front surface and the opening portion on the rear surface to prevent intrusion of floating dust and the like. Accordingly, the wave-powered pump device has its body 4 formed in a U-shape whose upper portion formed by the bottom plate 18 and the rectifying plate 17 is open. Therefore, when the main body is installed, for example, when it is installed on the seabed, the installation work is performed. And can be installed stably.
