Abstract:
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, a spherical intermediate housing and a spherical outer housing around the sphere centre, pairs of symmetric coaxial connecting shaft components 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; and each of the connecting shaft components in the two pairs being provided with a spring damper for resisting the axial impact between each two adjacent housings.

Claim (Index 2):
The self-balanced pressure hull device according to  claim 1 , wherein the two connecting shaft assemblies between the spherical intermediate housing and the spherical outer housing are of the same structure and size, and each connecting shaft assembly comprises a spring damper, a pedestal, a connecting shaft, a slide bearing, an inner bearing bush, an outer bearing bush, a bearing press plate, and a screw, the slide bearing being fixed on the connecting shaft via the bearing press plate and the screw; the inner bearing bush being disposed between an inner wall of the slide bearing and the connecting shaft; the connecting shaft being supported on the outer wall of the spherical intermediate housing; the pedestal being supported on the inner wall of the spherical outer housing; the outer bearing bush being disposed between an outer wall of the slide bearing and the pedestal; and the spring damper being mounted on an outer side of the pedestal ( 152 , 162 ), with two ends being tightly pressed against the connecting shaft and a protrusion of the pedestal respectively; and\n the two connecting shaft assemblies between the spherical inner housing and the spherical intermediate housing are of the same structure and size, and each connecting shaft assembly comprises a spring damper, a pedestal, a connecting shaft, a slide bearing, an inner bearing bush, an outer bearing bush, a bearing press plate, and a screw, the slide bearing being fixed on the connecting shaft via the bearing press plate and the screw; the inner bearing bush being disposed between an inner wall of the slide bearing and the connecting shaft; the connecting shaft being supported on the outer wall of the spherical inner housing; the pedestal being supported on the inner wall of the spherical intermediate housing; the outer bearing bush being disposed between an outer wall of the slide bearing and the pedestal; and the spring damper being mounted on an outer side of the pedestal, with two ends being tightly pressed against the connecting shaft and a protrusion of the pedestal respectively.
