Description

  This invention uses the fact that waves on the water surface change the pressure in the water to gradually compress the air and use the compressed air as energy to generate electricity directly, or carry and store the water at a high place to generate electricity when necessary. Used for, etc.

  Conventionally, as a method of extracting wave energy, there are many methods of extracting energy as electric power by directly applying a wave to a device.

As a method for extracting wave energy, many devices currently receive waves directly and often cannot be countered by natural forces and are often destroyed.
Since the present invention operates under the condition that it is submerged in water with a device that takes out the underwater pressure due to waves on the water surface as energy, it does not receive the force of waves directly and does not require a sturdy device.
It not only captures the energy of a single wave but also captures energy efficiently by capturing the entire wave for a long time.
Here, compressed air is used as energy. Power is generated directly with compressed air, or water is temporarily stored at a high position to make it easier to use.

From Fig. (1), this device has an air intake (5), a container (1) to a container (4) in order, and a pressure valve (6) that controls the flow of air between the pipes connecting the containers. And a pressure tank (9) for storing compressed air and a weight (13) for maintaining the position and posture.
In order from the container (1) to the container (4), the weight (13) is arranged so that the distance from the traveling direction of the wave is increased in consideration of the wavelength and depth of the wave at the place of installation, and the water depth is gradually increased from the shallower one. It arrange | positions with a pulley (14) and a weight (15).
The container (1) to the container (4) are connected in order by a pipe or a hose, and each container is partitioned by a pressure valve (6).
The air can be advanced only in the direction of the container (4) from the container (1) in order by the pressure valve (6). Does not occur.
The water level in the container rises and falls due to the underwater pressure around the container and changes the air pressure inside.
If the pressure received by the container when there is no wave is a static pressure, the static pressure around the container (4) is gradually increased from the container (1).
Here, when underwater pressure due to waves is applied around the container, each container is placed with a certain distance in consideration of the wavelength of the wave, so there is a difference in the pressure received by each container at the same time .
Here, if the sum of the static pressure around the container (1) and the pressure due to the waves is greater than the sum of the static pressure around the container (2) and the pressure due to the waves, the water level in both containers will rise and fall, and the air will It moves to the next higher static pressure vessel (2) and accumulates.
Similarly, the air gradually moves toward a container having a high static pressure, and air having a high pressure can be obtained in the pressure tank (9).
The pressure that can be accumulated in the pressure tank (9) can be approximately equal to the water pressure received by the container (4).

Most devices of the present invention are underwater and are not susceptible to the direct force of waves.
Since compressed air is produced, it is easy to transport and use, and the generator is directly driven by a compressed air motor.
Or, it is possible to use electric power when necessary by generating electricity while transporting water to a high position and storing it with compressed air.

An embodiment of the present invention is shown in FIG.
The structure from the container (1) to the container (4) is the same.
The bottom is open, and a mouth is provided through which air can be sucked and discharged.
A pressure valve (6) is a valve which advances air only in one direction by a pressure difference.
The pressure tank (9) is provided with a takeout port (10) that takes out the compressed air according to the purpose while accumulating the compressed air.
The floating body (7), the weight (13), the pulley (14), the weight (15), and the iron bar (16) are for appropriately arranging the position and depth from the container (1) to the container (4). is there.
The water level in the container is balanced when the water column pressure is equal to the internal air pressure, but if there is a change in pressure around the container, the water level in the container will rise and fall, changing the air pressure in it.
Although it is composed of the above, when installing it, the wavelength, period, water depth, etc. of the waves generated in the area are investigated in advance, and the distance and water depth between each container are determined.
From the air intake (5) to the pressure hose (8), a pipe and a hose are connected.
The container (1) to the container (4) are connected in the middle of the pipe and the hose, and a pressure valve (6) is attached between them so that the air advances only in one direction due to a pressure difference.
The pulley (14) is attached to the air intake (5) side, and the container (1) is deep enough to float and sink the water surface by the weight (15) attached to the end of the rope fixed to the sufficiently heavy weight (13). adjust.
A weight (13) is placed on the tip side of the iron bar (16), and the container (4) is sunk at an appropriate angle in order from the container (1) in the wave traveling direction and gradually deeper than the water surface.
If the pressure received by the container when there is no wave is a static pressure, the static pressure around the container (4) is gradually increased from the container (1).
Here, when underwater pressure due to waves is applied around the container,
Since each container is arranged with a certain distance in consideration of the wavelength of the wave, there is a difference in the pressure received by each container at the same time.
Here, if the sum of the static pressure around the container (1) and the pressure due to the waves is larger than the sum of the static pressure around the container (2) and the pressure due to the waves, the water levels in both containers will rise and fall, and the air will be Moves and accumulates in the next higher static pressure vessel (2).
In the same manner, the air gradually moves toward a container having a high static pressure, and the air that has passed through the pressure valve (6) from the container (4) passes through the pressure hose (8) and puts the air into the pressure tank (9). .
The air pressure accumulated in the pressure tank (9) is approximately the same as the water column pressure inside the container (4).
A compressed air motor is connected to the compressed air outlet (10) to generate electric power, or water is pumped and stored with a pump using compressed air, and hydroelectric power is generated as necessary.

Effects of the embodiment

Most devices are underwater and are not susceptible to direct wave forces.
The structure is simple and high-pressure air can be produced, so it is easy to transport air, or the pressure motor for direct power generation is turned on.
It is possible to generate electricity when it is needed while water is taken up and stored once with compressed air.

Other embodiments

Conventionally, in order to use wave energy, there are many forms in which it is directly used as electric energy, and it is difficult to control the amount.
Due to its nature, the equipment is fragile and equipment costs are high.

It is a perspective view which shows embodiment of this invention.
