Abstract

A wave receiving plate is pivotably supported by a support device in the wave force generation system and includes a flexible plate in at least a part of the wave receiving plate.

First claim

The invention claimed is:

1. A wave receiving plate assembly configured to form part of a wave power generation system, said wave receiving plate assembly configured to be pivotably supported by a support device in the wave power generation system, the wave receiving plate assembly comprising a first flexible plate having a first rigidity, and a second flexible plate disposed adjacent to the first flexible plate and having a second rigidity greater than the first rigidity;
wherein a lower end portion of the second flexible plate is disposed above a lower end portion of the first flexible plate.

2. The wave receiving plate assembly according to claim 1 , wherein a lower end portion of the first flexible plate is a free end.

3. The wave receiving plate assembly according to claim 1 , wherein the second flexible plate is disposed further on an incident wave side than the first flexible plate.

4. The wave receiving plate assembly according to claim 1 , further comprising a rigid plate configured to be connected to the support device, wherein the first flexible plate is supported by a lower portion of the rigid plate.

5. The wave receiving plate assembly according to claim 1 , wherein the first flexible plate comprises a rubber plate.

6. The wave receiving plate assembly according to claim 1 , wherein the first flexible plate comprises a viscoelastic plate.

7. The wave receiving plate assembly according to claim 1 , wherein the first flexible plate is a composite material of a rubber plate and a reinforcing member.

8. The wave receiving plate assembly according to claim 1 , wherein the first flexible plate is a composite material of a viscoelastic plate and a reinforcing member.

9. The wave receiving plate assembly according to claim 6 , wherein the viscoelastic plate comprises at least one of a urethane plate, a resin plate, a silicone plate, or a plastic plate.

10. The wave receiving plate assembly according to claim 7 , wherein the reinforcing member comprises at least one of synthetic fiber, semi-synthetic fiber, regenerated fiber, plant fiber, carbon fiber, animal fiber, metal fiber, metal wire, or metal plate.

11. The wave receiving plate assembly according to claim 10 , wherein the synthetic fiber comprises at least one of nylon, polyester, acrylic, polyvinyl chloride, polyurethane, vinylon, or aramid; the semi-synthetic fiber comprises at least one of acetate, triacetate, or promix; the regenerated fiber comprises at least one of rayon, cupro, or polynosic; the plant fiber comprises at least one of cotton or hemp; the carbon fiber comprises at least one of acrylic or pitch; the animal fiber comprises at least one of hair, angora, spider silk, or mohair; and the metal fiber comprises at least one of silver thread or steel thread.

12. A wave power generation system comprising: a wave receiving plate assembly according to claim 1 , further comprising a support device pivotably supporting the wave receiving plate assembly; and a power generation device that is operatively connected to the support device and configured to generate power based on a kinetic energy of the wave receiving plate assembly swinging by wave energy.

13. A wave power generation system comprising:
a support frame comprising a plurality of pillars configured to be fixed to an ocean floor, and a connecting plate supported by the pillars, the connecting plate configured to be disposed above an ocean surface in an installed configuration of the support frame,
a wave receiving plate assembly pivotably supported by the support frame, the wave receiving plate assembly comprising a first flexible plate having a first rigidity, and a second flexible plate disposed adjacent to the first flexible plate and having a second rigidity greater than the first rigidity, wherein a lower end portion of the second flexible plate is disposed above a lower end portion of the first flexible plate, and
a power generation device operatively connected to the support frame, the power generation device configured to generate power based on a kinetic energy of the wave receiving plate assembly swinging by wave energy.

14. The wave power generation system according to claim 13 , further comprising a rigid plate connected to the support frame, wherein the first flexible plate is supported by a lower portion of the rigid plate.

15. The wave power generation system according to claim 13 , wherein the first flexible plate comprises a rubber plate.

16. The wave power generation system according to claim 13 , wherein the first flexible plate comprises a viscoelastic plate.

17. The wave power generation system according to claim 13 , wherein the first flexible plate is a composite material of a rubber plate and a reinforcing member.
