Deep sea pressure resistant device

Abstract

The invention discloses a deep sea pressure resistant device. The deep sea pressure resistant device comprises a steel reinforcement framework which is in a shape of an eggshell and is symmetrical along the axis of the pressure resistant device; the inner layer and the outer layer of the steel reinforcement framework are both filled with concrete; the two ends of the steel reinforcement framework are the large end and the small end correspondingly; a man hole is formed in both the large end and the small end; one end of the man hole is connected with a man hole cover through a sealing gasket; the other end of the man hole is connected with a sight glass flange; the sight glass flange is connected with a sight glass base through a sealing gasket; a piece of sight glass glass is installed on the sight glass base; and the sight glass glass is fixed to the sight glass base through a hold-down ring. According to the egg-shaped concrete pressure resistant device, the effect that the eggshell can excellently resist uniformly distributed load, and the concrete pressure resistant characteristic is fully utilized, and an egg-shaped pressure resistant shell framework structure is built by means of steel reinforcements. The steel reinforcement layer serves as the middle surface, the interior and the exterior are filled with the concrete, the pressure resistant shell wall thickness is formed, the structure of the steel reinforcement framework is closer to the outline of a goose egg, and accordingly the pressure resistant characteristic of the structure is better achieved.

Description

technical field [0001] The invention relates to an egg-shaped concrete pressure-resistant device, which belongs to deep diving equipment. Background technique [0002] Submersibles are important equipment for ocean exploration and deep-sea scientific research. As an important part of the submersible, the pressure shell plays a role in ensuring the normal operation of internal equipment and the health and safety of personnel during the dive process. Its weight accounts for 1% of the total weight of the submersible. / 2-1 / 4. The design of the pressure hull has an important impact on the safety, carrying capacity and performance of the man-machine ring of the submersible. [0003] The pressure hull is a thin shell structure that withstands hydrostatic pressure. It is required to have good safety, reserve buoyancy, space utilization, and hydrodynamic characteristics to improve the overall performance of the submersible. The pressure hull of deep-sea submersibles is mostly a sph...

AI Technical Summary

Problems solved by technology

The pressure hull of deep-sea submersibles is mostly a spherical structure, which has the advantages of high strength, good stability, low buoyancy coefficient, and high material utilization rate, but the space utilization rate is low, the hydrodynamic properties are poor, it is quite sensitive to defects, and it is difficult to process and manufacture , unable to optimally coordinate the safety, carrying capacity and man-machine environment characteristics of the submersible
