Problems solved by technology

If the 4500m deep-sea submersible is doubled to 4m, the thickness of the manufacturing material also needs to be doubled, that is, a titanium alloy plate with a thickness of about 150mm-180mm is required, which is difficult to achieve with the current processing capacity

Abstract

The invention discloses a pressure-resistant housing of a deep-sea submersible, belonging to the field of deep-sea submersible. The pressure-resistant shell comprises an outer pressure-resistant spherical shell and an inner pressure-resistant spherical shell, and seawater is arranged in the cavity between the outer pressure-resistant spherical shell and the inner pressure-resistant spherical shell. A first relief valve is arranged on the outer side of the outer pressure-resistant spherical shell, a second relief valve is arranged on the outer side of the inner pressure-resistant spherical shell, and the second relief valve is arranged in a slow flow cavity on the inner pressure-resistant spherical shell; the outer side of the inner pressure-resistant spherical shell is also provided with ahigh-pressure gas cylinder which is connected with the cavity; an access hatch is arranged on the outer pressure spherical shell and the inner pressure spherical shell, an access hatch cover base isarranged on the outer pressure spherical shell and the inner pressure spherical shell at the access hatch, and an access hatch cover is arranged on the access hatch cover base; the invention solves the problem that the material requirement of the pressure-resistant shell is difficult to realize under the condition that the radius of the spherical shell with constant submergence is increased, and can ensure that the submergence is constant, and the external load of the structure is reduced while the radius of the spherical shell with constant submergence is increased, thereby ensuring the strength and stability of the structure.

Description

technical field [0001] Embodiments of the present invention relate to the field of deep-sea submersibles, in particular to a pressure-resistant shell of the deep-sea submersible. Background technique [0002] The deep-sea submersible is one of the important equipment for marine research at present, and it can carry scientific researchers into the deep sea for scientific research. The pressure-resistant shell is an important part to ensure the health and safety of researchers in deep-sea submersibles and the normal operation of equipment. Existing large-scale deep-sea manned submersibles have limited dry space, and the inner diameter of the manned spherical shell is only about 2m, which can carry limited scientific research personnel. [0003] [0004] σ represents the film stress of the spherical shell, t represents the thickness of the spherical shell, R represents the radius of the spherical shell, and P represents the calculated pressure. [0005] According to the ab...
