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 1):
A self-balanced pressure hull device, wherein assembled by successively nesting, from inside to outside, a spherical inner housing, a spherical intermediate housing and a spherical outer housing around the sphere centre,\n pairs of symmetric coaxial connecting shaft assemblies 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 assemblies being 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 assemblies in the two pairs being provided with a spring damper for resisting an axial impact between each two adjacent housings, wherein the spherical inner housing is formed by connecting a hemispherical inner housing I and a hemispherical inner housing II, the spherical intermediate housing is fondled by connecting a hemispherical intermediate housing I and a hemispherical intermediate housing II, and the spherical outer housing is formed by connecting a hemispherical outer housing I and a hemispherical outer housing II; pairs of symmetric limiting buffers are provided between the spherical inner housing and the spherical intermediate housing and between the spherical intermediate housing and the spherical outer housing, respectively; a connecting line of the limiting buffers between the spherical inner housing and the spherical intermediate housing is perpendicular to an axis of connecting shaft assemblies between the spherical inner housing and the spherical intermediate housing; and a connecting line of the limiting buffers between the spherical intermediate housing and the spherical outer housing is perpendicular to a connecting axis of the intermediate inner housing and the spherical outer housing; the spherical inner housing is provided with an inner compartment hatch, the spherical intermediate housing is provided with an intermediate compartment hatch, and the spherical outer housing is provided with an outer compartment hatch, the inner compartment hatch, the intermediate compartment hatch, and the outer compartment hatch being each disposed with a circular hatch cover; an inner hatch cover is connected to an inner wall of the inner housing via an inner hatch cover connecting pin-shaft assembly, tightly pressed by an inner hatch cover press plate mounted on the inner wall of the inner housing, and sealed by an O-shaped seal ring; an intermediate hatch cover is connected to an outer wall of the inner housing via an intermediate hatch cover connecting pin-shaft assembly, tightly pressed by an intermediate hatch cover press plate mounted on an outer wall of the intermediate housing, and sealed by an O-shaped seal ring; and an outer hatch cover is connected to an outer wall of the outer housing via an outer hatch cover connecting pin-shaft assembly, tightly pressed by an outer hatch cover press plate mounted on the outer wall of the outer housing, and sealed by an O-shaped seal ring; and an inner hatch cover hose connector is connected to an outer hatch cover hose connector via an inner compartment hose and connector assembly to connect an inner compartment inside the spherical inner housing with an external auxiliary submersible, so as to maintain a standard air pressure in the inner compartment inside the spherical inner housing; an intermediate hatch cover hose connector is connected to the outer hatch cover hose connector via an intermediate compartment hose and connector assembly to connect an intermediate compartment between the spherical inner housing and the spherical intermediate housing with the external auxiliary submersible, so as to maintain a vacuum in the intermediate compartment between the spherical inner housing and the spherical intermediate housing; and an outer compartment between the intermediate housing and the outer housing is connected to the external auxiliary submersible via the outer hatch cover hose connector, so as to maintain an air pressure in the outer compartment between the intermediate housing and the outer housing at a half of a hydraulic pressure outside the submersible at its working depth, the outer hatch cover hose connector being a three-tier metal connector in a nesting mode, with inner, middle, and outer tiers being respectively connected to the inner, intermediate, and outer compartments via metal hoses; and the inner hatch cover hose connector, the intermediate hatch cover hose connector and the outer hatch cover hose connector being respectively connected to the inner hatch cover, the intermediate hatch cover and the outer hatch cover through threads and sealed by O-shaped seal rings.
