Egg-shaped pressure-resistant shell device for self-balancing bathyscaphe

Abstract

The invention discloses an egg-shaped pressure-resistant shell device for a self-balancing bathyscaphe. The egg-shaped pressure-resistant shell device for the self-balancing bathyscaphe comprises an egg-shaped pressure-resistant shell. An observing window assembly is arranged at the big-head end of the egg-shaped pressure-resistant shell, and an egg-shaped head-sealed assembly is arranged at the small-head end of the egg-shaped pressure-resistant shell; and a balancing seat system connected with the inner wall of the egg-shaped pressure-resistant shell is arranged in the short-shaft direction of the egg-shaped pressure-resistant shell, and an inertial navigation measurement system is arranged on the upper inner wall of the egg-shaped pressure-resistant shell corresponding to a middle line of the balancing seat system. According to the egg-shaped pressure-resistant shell device for the self-balancing bathyscaphe, vertical diving and floating modes are adopted, the big end of the egg-shaped pressure-resistant shell is kept to be same with the moving direction all the time, a streamline structure of an egg-shaped shell body is utilized, resistance is small, diving and floating time is shortened, and underwater working efficiency is improved. The egg-shaped pressure-resistant shell device for the self-balancing bathyscaphe is simple in structure, small in size and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of deep-sea submersibles, and relates to a pressure-resistant device for a deep-sea submersible, in particular to an egg-shaped pressure-resistant shell device for a self-balancing deep-sea submersible. Background technique [0002] As the speed of ocean development continues to accelerate, the depth of exploration from the offshore to the far sea continues to increase. There are many types of submersibles for various operating purposes and they are developing rapidly. They are mainly used in marine resource exploration and development, scientific research, military detection and salvage. 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 10% of the total ...

AI Technical Summary

Problems solved by technology

[0003] 1. At present, the pressure hulls of deep-sea submersibles are mostly spherical structures, and the spherical shells are completely symmetrical shells, which are highly sensitive to defects, and small initial defects will cause a sharp drop in their carrying capacity

For example, for a titanium alloy spherical pressure vessel with a diameter of 2m and a thickness of 20mm, a defect with a magnitude of 3mm will cause its buckling critical load to drop by 25.6%.

[0004] 2. The pressure hull of deep-sea submersibles is mostly a single spherical shell structure, and the divers and instruments and equipment are in the same room. The use of space is unreasonable, which is not conducive to the manufacture and maintenance of submersibles

[0005] 3. The deployment and recovery of the deep-sea submersible will cause severe shaking, and the environment is not comfortable

The balance device designed by the patent No. ZL201510586853.2 (a self-balancing pressure vessel device) and ZL201510746100.3 (an active balancing pressure vessel device and its control method) has a complex structure, a large volume, high manufacturing cost

[0006] 4. Deep-sea submersibles mostly use horizontal methods for diving and surfacing, with large body surface area, large resistance, long time for diving and surfacing, and low work efficiency
