Problems solved by technology

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 stability problems are unfavorable to the ultimate bearing capacity of the pressure body

Abstract

A deep-sea submersible pressure body limit and shrinkage deformation compensation device and installation method thereof, comprising a pressure body, outer rib panels arranged in parallel at intervals on the outer circumference of the pressure body, spaced from one of the outer rib panels A non-pressure-resistant structure is nested, and the bottom of the non-pressure-resistant structure is extended with an inner panel perpendicular to it. The inner panel and the outer rib panel are arranged in parallel and at intervals, and multiple compensations are welded between the inner panel and the outer rib panel. device, a plurality of compensation devices are evenly spaced and distributed in the circumferential space between the inner panel and the outer rib panel. The compensation device is between the pressure-resistant body and the non-pressure-resistant structure, which can replace the traditional direct welding connection method between the non-pressure-resistant structure and the pressure-resistant body of the submersible, and can decouple the non-pressure-resistant structure and the pressure-resistant body on the connection boundary , so that the non-pressure-resistant structure is free from the strength and stability problems caused by the implicated deformation of the pressure-resistant body, and it can also avoid the strength problem caused by the non-uniform deformation of the pressure-resistant body due to the restraint of the non-pressure-resistant structure.

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...
