DEVICE OF CHANGING BUOYANCY AND MACHINE OF GATHERING ENVIRONMENTAL INFORMATIONS UNDER WATER USING THE DEVICE

摘要

The buoyancy converting apparatus of the present invention comprises a rigid body, a flexible body, and the non-compressive fluid pump. Rigid body is possible to maintain a constant volume deformation without underwater high water pressure, the flexible body is formed of a material capable of deformation may vary depending on the volume and out the non-compressive fluid. Non-compressible fluid is the buoyant force exerted on the buoyant converter changes in accordance with the sense of coming a rigid body and the flexible body by the pump, it is possible that the buoyancy conversion device move up and down by the buoyancy change. Buoyancy conversion device may repeat as used in the apparatus of small material out without, and may change the buoyancy to move a certain amount of incompressible fluid, the rising and falling into infinity if only provide enough energy, this also works with low power since it is possible it is possible to perform an operation that requires a long period of time while remaining in the ocean.
