DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a vertical sectional view of a compressed air manufacturing apparatus. That is, the container body 1 is cylindrical and has a piston 2 having a disk-shaped head 3 and a shaft portion 4 therein. The inside of the container body 1 is divided by a disk-shaped head 3 into an upper hydraulic chamber 5 and a lower air chamber 6. The water pressure chamber 5 is formed with an inflow port 7 having a size large enough to allow free entry of water from the outside. The air chamber 6 is provided with a valve 8 for controlling the inflow of air. Further, the container body 1 has a holding portion 9 that allows the piston shaft 4 to move up and down, but fixes the position. Therefore, when the water pressure increases, the air chamber 6
It is pushed and compressed. This air chamber 6
A compressed air recovery container 11 is connected to the compressed air recovery container 11 via a connection pipe 10. A check valve 12 is attached to the connecting pipe 10. The compressed air recovery container 11 has an extremely small inner volume as compared with the inner volume before the reduction of the air chamber 6 so as to maintain the compressed state of the compressed air, and has a structure with little deformation. Further, the backflow prevention valve 12 allows the air to flow into the recovery container 11 only when the pressure in the air chamber 6 is larger than that of the compressed air recovery container 11, but when the pressure relationship is opposite, the compressed air recovery container 11 is pressed. It works so that the compressed air inside does not flow back into the air chamber 6. The compressed air recovery container 1
1 has a structure that can be replaced from the container body 1. A sinking weight attachment device 13, which will be described later, is attached to the lower portion of the container body 1, and a buoyant body 14 for floating is provided on the upper portion of the container body 1. The buoyant body 14 may be separately manufactured as shown in FIG. 2 and attached to the container body 1 by the rod 15, but in the case of FIG. 1, the piston 2 and the piston holding portion 9 are hollow so that air can be enclosed inside. It also serves as a buoyancy body.

FIG. 2 shows a vertical sectional view of another embodiment of the compressed air producing apparatus. In the embodiment of FIG. 2, the buoyant body 14 is spherical and is attached to the container body 1 by the rod 15 so that the compressed air recovery container 11 and the buoyant body 14 are used in common. The internal volume of the compressed air recovery container 11 is shown in FIG. The structure is exactly the same as that of FIG. 1 except that it is made larger than that of FIG. 1 and that the sinking weight 16 is directly attached to it. The usage is different when the compressed air recovery container 11 is used.

The sinking weight 16 in FIG. 1 is housed in a box 17 suspended from the bottom of the container body 1 in the case of an indeterminate object such as sand, and the bottom 18 of the box 17 opens by its own weight. It is like this. A wire 19 is attached to the bottom portion 18 and attached to the clamp portion 20 of the sinking weight attaching device 13. The sinking weight 16 in FIG. 2 is a unitary weight or a lump in which several units are combined into one.
The wire 19 for attachment is attached to the clamp part 20 of FIG. In either case, the mounting device will drop when the clamp is opened.

The mechanism for opening and closing the clamp portion 20 of the sinking weight attachment device 13 is common to FIGS. 1 and 2. In the wrench-shaped holder 21, the holder rotating shaft 22 has a mounting bracket 23.
Is fixed to the container body 1. The sinking weight 16 is held when the wire 19 of the sinking weight 16 is closed and the closing pin 25 is fitted into the cylindrical ring 24 in the upper portion in a closed state. On the other hand, tension spring 2
6 is attached between the arm 27 fixed to the container body 1 and the columnar ring 24 immediately below the adjacent column, and the closing pin 25
When the tool is removed, the holder 21 is opened and the sinking weight 16 is dropped. Next, a mechanism for fitting and withdrawing the closing pin 25 will be described. The closing pin 25 is attached via a hinge to one side of a lever girder 30 that rotates around a lever shaft 29 provided on a lever mounting arm 28 fixed to the container body 1, and to the other side of the lever girder 30 with the container body 1.
A push-down rod 31 projecting through the air chamber 6 is mounted on the push-down rod 31. When the piston 2 descends and pushes the push-down bar 31 downwards, the closing pin 25 is pulled out from the cylindrical ring 24 by the lever action. The length of the push-down bar 31 has a function of determining the position of the piston 2 where the sinking weight 16 is cut off. Installation of the push-down rod 31 and fitting of the closing pin 25 can be performed manually when the container body 1 is pulled up into the atmosphere.

The buoyant body 14 is a container containing air for giving a buoyancy for recovering the compressed air recovery container 11 and the container body 1 after removing the sinking weight 16.
The shape may be a box shape as shown in FIG. 1, but a spherical shape is structurally advantageous as shown in FIG. Structural materials such as steel are strong in tension but weak in compression due to the slenderness ratio. Therefore, when the water depth is large, it is advantageous to fill the inside of the buoyancy body 14 with compressed air having a pressure close to the water pressure because the pressure difference between the inside and outside is small.

In the case of FIG. 1, the sinking weight may be that of FIG. In both cases of FIG. 1 and FIG. 2, when the air inlet valve 8 of the container body 1 is opened and the upper part of the piston shaft 4 is held and hung by a crane, air flows into the air chamber 6 due to the weight of the container body 1 The volume of the chamber 6 is maximized. Therefore, the air inflow valve 8 is closed, and the compressed air recovery container 11 and the buoyant body 14 are closed.
Then, the sinking weight 16 is attached to the spanner-shaped holder 21, the push-down bar 31 is set, the closing pin 25 is fitted into the cylindrical ring 24, and the tension spring 26 is attached. When the water is gently lowered into the water, the water flows into the water pressure chamber 5, the piston 2 is pushed down by the water pressure, and part of the water is compressed into the compressed air recovery container 11 due to the volume reduction of the air. When the descent is further continued, the water pressure further increases, the air pressure increases, and most of the air enters the compressed air recovery container 11, so that the head 3 of the piston 2 pushes down the push-down rod 31 at the same time as the closing pin. 25 is pulled upward, the spanner-like holder 21 is opened by the action of the tension spring 26, the sinking weight 16 is cut off from the clamp portion 20, and the container body 1 is raised by the action of the buoyant body 14. When the surface of the water is reached, the compressed air recovery container 11 is recovered. Since the check valve 12 is provided in the connection pipe 10 with the compressed air recovery container 11, high pressure recovery is possible. The same can be repeated after opening the air inflow valve 8.

In the case of FIG. 2, the sinking weight shown in FIG. 1 can be used. The necessary volume of the buoyant body 14 is mainly the container body 1, the compressed air recovery container 11, the sinking weight attaching device 13
Determined from the total weight of the ascending. In the apparatus shown in FIG. 2, the compressed air recovery container 11 is also used as the buoyancy body 14. If compressed air having a pressure close to water pressure is enclosed in the buoyancy body 14, the pressure difference between the inside and the outside becomes small, and it is possible to withstand a high water pressure when it reaches a deep place in water, which is structurally advantageous. In the apparatus of FIG. 2, the compressed air recovery container 1
Since 1 is the buoyant body 14, even if the internal volume of the compressed air recovery container 11 is made large according to the internal volume of the compressed air recovery container 11, it is press-fitted into the compressed air recovery container 11. Even when the compressed air is kept in the container 11 and submerged in water and the air is replenished in the air chamber 6 repeatedly, even when the compressed air is gradually submerged to a deep water depth, the water pressure can be dealt with. Then, high-pressure compressed air corresponding to the internal volume thereof is press-fitted into the compressed-air recovery container 11, and the presence of this press-fitted high-pressure compressed air causes the compressed-air recovery container 11, that is, the buoyant body 14, to move to a high water pressure in the deep sea. Can withstand. As described above, in the device of FIG. 2, the compressed air recovery container 11 is also used as the buoyant body 14, and therefore the pressure of the compressed air pressurized in the compressed air recovery container 11 is gradually increased according to the depth of water to be sinked. It is possible to withstand the high water pressure in the deep sea by going forward, and it is suitable to obtain high-pressure compressed air corresponding to the internal volume of the compressed air recovery container 11 due to the high water pressure in the deep sea.

According to the conventional usage form of compressed air, energy obtained by another method is converted into compressed air and then converted into power suitable for the purpose of use, which is the final purpose of machine tools and measurement. It has been used in various fields such as air conditioning and labor saving, and can be said to be a secondary use form of energy. At present, we rely on fossil fuels and nuclear power as energy sources necessary for civilized society, so we are facing many problems such as reserve constraints, serious accidents, and environmental pollution due to waste. . The present invention is such that sealed air is submerged in water using a weight, compressed, and allowed to float and recover using the buoyancy with the volume as it is, for example, a sinking weight. Compressed in water such as in the sea, except for energy for mounting, energy for crane operation to suspend the device with a crane and sink to the sea, etc. The gravity action of the sinking weight, the hydraulic action, and the buoyancy action due to the hydraulic pressure, which are necessary in the process of obtaining air, use natural energy, and the sinking weight consumed is any substance if the specific gravity is greater than that of water. But you can use it. As described above, the present invention can mainly use natural energy to create a non-polluting energy called compressed air, and can solve the energy problem that may be a factor of the problem of global environmental pollution and the limit of growth of civilized society. It will be a powerful tool.
