Problems solved by technology

However, since the pressure resistance of the flat plate structure and cylindrical structure with the same caliber and thickness is far inferior to that of the spherical structure, the material required for this structure is thicker, heavier and not light enough

Abstract

The invention provides a pressure-resistant sealing structure of an imaging system. The structure comprises a hemispherical light-transmitting cover, a light shield, a sealing ring pressing ring, a light-transmitting cover base, a pressure-resistant cylinder, a rear end cover and an electrical interface; according to the pressure-resistant sealing structure of the imaging system, the transparent ceramic is adopted as an optical window of the hemisphere light-transmitting cover, the pressure resistance is better, the main body structure is of a spherical structure, and sealing design is conducted according to the characteristics of the hemisphere structure, so the sealing performance is better; as the main body structure adopts the spherical structure, the stress distribution is uniform, the stress concentration is not easy to occur, and the pressure resistance and portability are realized.

Description

technical field [0001] The invention relates to the technical field of deep-sea imaging, in particular to a pressure-resistant sealing structure of an imaging system. Background technique [0002] With the depletion of land resources, human beings are increasingly marching into the deep sea. In the past 10 years, there have been more and more marine scientific expeditions and research activities in marine biology, marine mineral resources, marine ecological environment, marine environmental pollution investigation and control, marine geophysics, marine climate and atmosphere, marine chemistry, and marine geology. Frequently, deep-sea equipment is becoming more and more active in marine research, and its role is becoming more and more important. The collection, analysis, cultivation and research of deep-sea biological genes under the conditions of heat preservation and pressure preservation in the deep ocean will have an important impact on human science and life.
