深海用均圧装置を提供しようとするものである。Therefore, the present invention is intended for deep sea applications that can withstand use in the deep sea by equalizing the internal pressure and the external pressure without increasing the thickness of the conventional container and making the container itself pressure resistant. It is intended to provide a pressure equalizing device.

It shows the change situation between 2 and seawater W. First, as shown in FIG. 2A, the internal pressure of the main body container 1 is set to be slightly higher than the external atmospheric pressure on the ship. Next, from FIG.
As shown in (F), when it is gradually lowered into the sea, the internal pressure of the main body container 1 gradually rises due to the pressure of the hydrogen gas H 2 generated by the evaporation of the liquid hydrogen 5a. At this time, when the internal pressure of the main body container 1 becomes too higher than the water pressure, the hydrogen gas H 2 is supplied to the seawater W by the gas equalizing valve 11.
It is released inside (see FIG. 2C) or released into the seawater W by the relief valve 13 (see FIG. 2D). On the other hand, when the internal pressure of the main body container 1 becomes too lower than the water pressure, the seawater pressure equalizing valve 12 causes the seawater W to flow into the main body container 1 and the outlet of the oil heater 10 is increased (ON in FIG. 2). See F)). At this time, in any case, the lowering speed is adjusted so that the external pressure inside the main body container 1 is kept within a certain range. Furthermore, after landing, (F) in FIG.
As shown in (I), if the internal pressure decreases with the use of the hydrogen gas H 2 , the seawater W equalizing valve 12 allows the seawater W to flow into the main body container 1 to maintain the equalizing pressure. In addition, in FIG.
When the internal pressure of the main body container 1 is P 1 and the external pressure is P 0 , these relationships are P 1 = P 0 +1 to 2 in the case of (A) and (B).

Since the internal pressure and the external pressure of the storage container 18 can be equalized by the nitrogen gas N 2 generated in the gas generation tank 6 of II, the container 18 can be a pressure equalizing container and the thickness of the container 18 itself can be reduced. Can be thinned. Next, FIG. 4 shows another embodiment of the present invention. As with the deep sea pressure equalizer shown in FIG. 1, a gas generation tank 6 containing liquid hydrogen 5a is installed at an upper position in the main body container 1. However, in a configuration in which the gas supply pipe 2 is connected to the top of the main body container 1 and the relief valve 13 is provided on the side wall of the main body container 1, at a position lower than the gas generation tank 6 in the main body container 1, A piston 24 containing an oil heater 23 is slidably fitted in a vertical direction via a seal ring, and the pressure of seawater W acting through an opening 25 provided in the bottom plate 3 and hydrogen gas generated in the gas generation tank 6 It is designed such that it can be moved up and down based on the difference with the pressure of H 2 . In addition, in FIG.

が円滑に行われる。In the case of the embodiment shown in FIG. 4, the hydrogen gas H 2 generated in the gas generation tank 6 is used to compensate for the volume reduction due to the increase in water pressure when the main body container 1 descends in the sea. After landing, most of the water can be fed to a fuel cell or the like. At this time, changes in water pressure and internal pressure of the main body container 1 can be absorbed mainly by vertical movement of the piston 24, and vertical movement of the piston 24 The pressure change that cannot be absorbed can be compensated by adjusting the descending speed and operating the relief valve 13. Further, since the oil heater 23 is built in the piston 24, warming the piston 24 with the oil heater 23 does not cause the piston 24 to freeze due to the cold heat of the hydrogen gas H 2 , and the piston 24 can move up and down. It will be done smoothly.

である。In the above embodiment, liquid hydrogen 5a, liquid oxygen 5b, and liquid nitrogen 5 are placed in the gas generation tank 6.
Although the case where a low-temperature liquefied gas that becomes a gas by evaporation and increases in volume such as c is stored is shown, a substance (for example, a hydrogen storage alloy) that generates gas due to a change in temperature or pressure is stored. It goes without saying that various changes can be made without departing from the scope of the present invention.

図ることができる、等の優れた効果を発揮する。As described above, according to the pressure equalizer for deep sea of the present invention, the difference between the pressure of the gas generated in the gas generation tank in the pressure equalizer main body container and the pressure of seawater acting from the outside. Is absorbed by the operation of the pressure equalizing valve or the vertical movement of the piston so as to balance the internal and external pressures of the main body container, so that the pressure equalizing system can be used when used in the deep sea. The thickness of the main body container can be reduced by this, and cost reduction, weight reduction, and size reduction can be achieved.In addition, for equipment that consumes gas, such as fuel cells, it can be used as a gas generation tank. By selecting the gas source to be stored, the generated gas can be used for consumption as it is, so it can be used as a deep-sea gas supply device, and the system such as the fuel cell can be simplified. It exhibits an excellent effect and the like.
