3 and a specific gravity adjusting device 14 as a mechanism for injecting the substance into the space as required and / or a mechanism for discharging the substance from the space as required. The other points were the same as in FIG.

Hereinafter, features of the power supply device according to the present embodiment will be described in detail. (1) When transporting the power supply device, the specific gravity of the entire power supply device can be reduced by placing the air chamber 13 in a state in which a gas such as air is contained or in a vacuum state. The device in this state can float with a buoyancy in a liquid having a high specific gravity, such as water, so that it can easily move while floating on the water surface.

(2) When the power supply device is fixed in water, it is more convenient for the main body of the power supply device to be heavier, so that water is injected into the air chamber 13 using the specific gravity adjusting device 14 on the water surface, and And other gases. As a result, the specific gravity of the entire power supply device increases, and the power supply device that has floated when it has become larger than the surrounding water can be settled, and can be stably fixed at a predetermined place.

(3) If the power supply device fixedly installed in water has a reduced capacity or a failure, it is necessary to repair the power supply device by resurfacing on the water surface. In this case, a great deal of labor is required to float the power supply unit when the power supply unit remains heavy. Therefore, the above-described specific gravity adjusting device 14 is operated, and the air chamber 13 is operated.
The air chamber 13 is evacuated by injecting a gas, such as air, and discharging water, or by discharging water. As a result, when the overall specific gravity of the power supply device is reduced and becomes smaller than the surrounding water, the power supply device can be floated on the water surface without much labor, and a desired treatment can be performed.

As described above, by providing a highly waterproof and integrated exterior, and by providing a mechanism capable of adjusting the specific gravity of the entire apparatus, convenience in a solution for rivers, oceans, industrial use, and the like can be obtained. Power supply device can be realized.

When the floating operation of the device by frequent specific gravity adjustment is unnecessary, the above-described specific gravity adjusting device 14 inside the power supply device is abolished. For example, an inlet and an outlet for adjusting the specific gravity are provided on the exterior of the power supply device. And the specific gravity of the same device as described above may be externally adjusted.

Further, if a medium having a boiling point near the ambient temperature at which the power supply device is used is used, the specific gravity can be changed by changing the temperature of the medium, and the injection or discharge of a medium having a high specific gravity such as water can be performed. It is also possible to make it easier.

[0035]

As described above, according to the present invention,
In a power supply unit that combines a power supply source and a control unit, by integrating the exterior of the power supply source and the exterior of the control unit, it is possible to achieve low cost, miniaturization, excellent portability and waterproofness, and convenience. It is possible to provide a highly reliable power supply device.

Further, according to the present invention, by providing a mechanism for varying the specific gravity of the entire power supply device, the device can be easily moved on or in the liquid, and the device can freely move up and down in the liquid. Thus, a power supply device that can be controlled at a constant speed is obtained.
