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 3):
The self-balanced pressure hull device according to  claim 1 , wherein the two limiting buffers between the spherical inner housing and the spherical intermediate housing are of the same structure and size, and each limiting buffer comprises an upper support plate, a middle support plate, a lower support plate, an upper hydraulic damper, and a lower hydraulic damper, the middle support plate being welded to the outer wall of the spherical inner housing; the upper support plate and the lower support plate being respectively disposed on a lower support plate upper pedestal and a lower support plate lower pedestal which are connected to the inner wall of the spherical intermediate housing; the upper hydraulic damper and the lower hydraulic damper being symmetrically arranged about the middle support plate; one end of each of the upper hydraulic damper and the lower hydraulic damper being connected to the middle support plate via a universal joint; the other end of the upper hydraulic damper being connected to the upper support plate via a universal joint; and the other end of the lower hydraulic damper being connected to the lower support plate via a universal joint; and\n the two limiting buffers between the spherical intermediate housing and the spherical outer housing are of the same structure and size, and each limiting buffer comprises an upper support plate, a middle support plate, a lower support plate, an upper hydraulic damper, and a lower hydraulic damper, the middle support plate being welded to the outer wall of the spherical inner housing; the upper support plate and the lower support plate being respectively disposed on a lower support plate upper pedestal and a lower support plate lower pedestal which are connected to the inner wall of the spherical intermediate housing; the upper hydraulic damper and the lower hydraulic damper being symmetrically arranged about the middle support plate; one end of each of the upper hydraulic damper and the lower hydraulic damper being connected to the middle support plate via a universal joint; the other end of the upper hydraulic damper being connected to the upper support plate via a universal joint; and the other end of the lower hydraulic damper being connected to the lower support plate via a universal joint.
