PROBLEM TO BE SOLVED: To fulfill a requirement that many methods for directly getting wave motion as wave energy at present need a solid device.SOLUTION: Each of variable volume containers 1 to 4 is sunk to a level that gets deeper in order from the container 1 to the container 4, and air in these containers only flows in the direction from the container 1 toward the container 4. When wave occurs at a water surface, this wave generates a pressure in water that changes as time elapses. The strength and a direction of the pressure acting on each of the containers are different from each other at a certain instant. In the case that a total value of stationary pressure and water pressure by wave acting on the variable volume container 1 is larger than a total value of stationary pressure and water pressure by wave acting on the variable volume container 2, partial air in the variable volume container 1 is fed to the variable volume container 2 and accumulated therein. In this way, air is sent gradually toward the container having a higher stationary pressure,and then this air has a pressure higher than the stationary pressure in the variable volume container 4, thereby being sent to a pressure tank 9. This compressed air is used for operating a motor, which then generates electricity. |
