In order to connect the rotational force of the impeller 5 with a spiral rotary machine, which is pivotally supported by the single shaft shaft 4, to the generator 12 to generate electric power, a rotating body adjusting device such as a fly hole is used to match the rotation speed of the generator. It is necessary to prepare 11, and it is necessary to install a transformer regulator 13, a distribution board 14, and the like in order to match the generated power with the used power.

The generated electric power is wired from the transformer regulator 13 and the distribution board 14 so as to cover the blower 1, and the surplus electric power is used as the supplied electric power.

The power generation device using the buoyancy of air in water according to the present invention is effectively installed at a small power generation scale of several kilowatts to several tens of kilowatts, and generates the compressed air as the energy. Since the function of the blower 6 is limited to 15 meters or less even if the water depth is deep, the air having a low pressure from the blower 6 is placed at a point where the compressed air is discharged into the water, and the water having a high water pressure, such as the water, is placed. Since it is a mixture with liquid, it can be used even with a blower with weak water pressure, and a fan type or blower type can sufficiently cover it.
