A self-balanced pressure hull device, belonging to the field of pressure structure technology of deep-sea submersibles, being assembled by nesting, from inside to outside, a spherical inner housing (1, 2), a spherical intermediate housing (3, 4) and a spherical outer housing (5, 6) around the sphere centre; pairs of symmetric coaxial connecting shaft components (15,16,17,18) being connected between the spherical inner housing and the spherical intermediate housing and between the spherical intermediate housing and the spherical outer housing, respectively, axes of the two pairs of connecting shaft components are perpendicular to each other so as to enable the spherical inner housing and the spherical intermediate housing to rotate relative to each other, and the spherical intermediate housing and the spherical outer housing to rotate relative to each other; each of the connecting shaft components in the two pairs being provided with a spring damper (151,161,171,181) for resisting the axial impact between each two adjacent housings. Said device simplifies the control system, improves the operation reliability and running stability of the submersible, reduces the noise inside the compartment, improving the comfort of the working environment of submerged members; improves the operation security of the submersible, broadens the range of optional materials, reduces the thickness of the housings, reducing the difficulty of processing the housings.
