Technical Field

The ocean accounts for 71 percent of the surface area of the earth, the ocean surface has the phenomena of sea waves and tides, the sea wave energy mainly comes from the gravity of the heaven and the wind energy and the like, and the sea wave energy is invariable depending on the ancient times; the tide is mainly related to the gravity of moon and sun to the earth, generally, the tide is a more regular half-day tide, namely, the tide is once every 12 hours, and the tidal range is different according to different sea areas, for example, the tidal range in China has a tendency of gradually increasing from north to south and has higher randomness. The ocean energy lays a foundation for human to develop ocean energy by the advantages of cleanness, stability, huge energy, inexhaustibility and the like. The development of sea wave energy has been widely regarded worldwide, the sea wave energy is a combination of kinetic energy and potential energy, the two energies depend on each other, the trade-off is large, and the development forms are various. The method is also one of the methods, the compressed air is widely utilized, and the compressed air can be used for pushing a turbine to generate electricity and the like.

In the process of obtaining compressed air by using the energy of sea waves by adopting a buoy-cylinder structure, tides play a role in blocking. In the process that the sea waves push the buoy-cylinder to obtain compressed air (the height of the cylinder and the sea bottom is fixed), along with the rise tide and the fall tide (the height of the sea level is changed), the buoy gradually rises or falls to shorten the stroke of the piston or separate from the sea surface to lose the buoyancy of the sea water, so that the sea wave energy cannot be effectively captured, and the compressed air cannot be discharged or cannot be compressed; the air cylinder only compresses air in a limited height when the tidal range rises or falls, and cannot obtain the compressed air in the whole course of the tidal range, so that the utilization efficiency of the wave energy is greatly reduced.
