Deep sea submersible vehicle pressure-proof body limiting and shrinkage deformation compensating device and mounting method thereof

Abstract

The invention provides a deep sea submersible vehicle pressure-proof body limiting and shrinkage deformation compensating device and a mounting method thereof. The deep sea submersible vehicle pressure-proof body limiting and shrinkage deformation compensating device comprises a pressure-proof body, wherein outer rib panels are arranged in parallel on the outer circumferential surface of the pressure-proof body at intervals, non-pressure-proof structures sleeves the outer rib panels at intervals, inner panels perpendicular to the non-pressure-proof structures are arranged at the bottoms of the non-pressure-proof structures in an extending mode, the inner panels are arranged in parallel to the outer rib panels at intervals, a plurality of compensation device bodies are welded between the inner panels and the outer rib panels, and the compensating device bodies are evenly distributed in the circumferential space between the inner panels and the outer rib panels at intervals. The deep sea submersible vehicle pressure-proof body limiting and shrinkage deformation compensating device can replace a traditional direct welding connection method between the non-pressure-proof structures and the pressure-proof body of a submersible vehicle between the pressure-proof body and the non-pressure-proof structures, the non-pressure-proof structures can be decoupled from the pressure-proof body at the connection boundary, thus, the non-pressure-proof structures are prevented from being affected by the deformation of the pressure-proof body to cause strength and stability problems, and the strength problem caused by the pressure-proof being restrained by the non-pressure-proof structures and being unable to be uniformly deformed can be solved.

Description

technical field [0001] The invention relates to the technical field of compensation devices, in particular to a compensation device for position limiting and shrinkage deformation of a deep-sea submersible pressure body and an installation method thereof. Background technique [0002] The pressure shell structure of the submersible requires light weight, good economy, high structural efficiency and good reliability. When in use, it usually needs to be matched with a non-pressure-resistant shell. In the prior art, the non-pressure-resistant structure of the submersible is directly welded with the pressure-resistant body to provide an installation basis for the outboard equipment. With the increase of the working depth of the submersible, the pressure body has large radial and longitudinal shrinkage deformation under the deep sea pressure, which will implicate the longitudinal and transverse non-pressure structures welded on the pressure body, resulting in Strength and stabil...
