Wave advance and retreat ports for wave energy harvesting means installed on the coast, etc.
It is necessary to keep the opening below the sea level even at low tide, but when the opening is deep below the sea surface, it is difficult to collect the kinetic energy that accounts for i of wave energy, and conversely, it is necessary to collect wave energy including kinetic energy. In order to achieve this, it is necessary to open the wave entrance and exit close to the sea surface.
The problem is that at low tide, the apocalypse is exposed, no air chamber is formed, and the energy harvesting function is lost.

弁状態を保っている。1. When the water surface forms a sealed air chamber in the wave energy harvesting means, the water surface rises and falls repeatedly due to the lapping and receding waves that match the wave cycle, changing the volume of the air chamber. , wave energy is converted into air pressure energy by alternately generating positive pressure and negative pressure. To explain the operation of the method of the present invention using Fig. 1, (during wave crashing stroke) (1) When position M is X, (at high tide) the wave energy harvesting means 1 fixed at a high position opens the wave advance/retreat port 11 close to the tide level 2, a positive pressure difference is generated between the upstream side 6A of the discharge check valve and the downstream side 6B of the discharge check valve 6, and the discharge check valve 6 is opened. Then, the positive pressure air flows out from the air chamber 2 to the downstream side 6B of the discharge check valve through the upstream side 6A, becomes an air flow, and flows into the air turbine 3 through the air supply flow path 7 and the air turbine air supply end 3A,
After operating the air turbine 3 and generator IO to convert air pressure energy into electrical energy, the air flows through the air turbine exhaust end 3B to the upstream side 4A of the exhaust check valve, and between the upstream side 4A and downstream side 4B. The positive pressure difference causes the exhaust check valve 4 to open, and the flow flows through the exhaust check valve 4 to the downstream side 4B of the valve.
It acts so that it flows out into the atmosphere. The atmospheric check valve 4 and the laughing gas check valve 8 are kept closed by the above positive pressure. On the other hand, wave energy harvesting means 1 fixed at a low position
Since ' is below the tide level When the pressure in the air supply passage 7 caused by the sampling means 1 is higher and a positive pressure difference occurs between the upstream side 6'A of the discharge check valve and the downstream side 6'B of the discharge check valve, the discharge check valve 6' is opened. valve and operates in the same manner as above. The laughing gas check valve 8' is kept closed by the negative pressure regardless of whether the discharge check valve 6' is opened or closed.

(At high tide) Negative pressure is generated in the air chamber 2 of the wave energy harvesting means 1 due to the drop of the water surface, and a positive pressure difference is created between the upstream side 8A and the downstream side 8B of the laughing gas check valve. The laughing gas check valve 8 is opened.

0 is activated to convert the pressure energy of the air into electrical energy, the air passes through the air turbine exhaust end 3B and the laughing gas flow path 9 to the upstream side of the laughing gas check valve 8A, where the laughing gas check valve 8 is opened. , and flows into the air chamber 2 from the downstream side 8B of the valve. The exhaust check valve 5 and the discharge check valve 6 are kept closed by the above negative pressure. On the other hand, the wave energy harvesting means 1' also generates negative pressure in the air chamber 2',
This negative pressure is lower than the laughing gas flow path 9 and the upstream side of the laughing gas check valve 8'
When a positive pressure difference is generated between A and the downstream side 8'B, the laughing gas check valve 8' is opened and operates in the same manner as described above. The exhaust check valve 5' is kept closed by negative pressure regardless of whether the exhaust check valve 8' is opened or closed.
