A bionic pressure-resistant device

Abstract

The invention discloses a bionic pressure-resisting device. The bionic pressure-resisting device comprises a plurality of egg-shaped bionic pressure-resisting shells, and the two ends of each egg-shaped bionic pressure-resisting shell are a blunt end and a sharp end; the blunt ends and the sharp ends of the adjacent egg-shaped bionic pressure-resisting shells are sequentially connected through a shell connecting device, and an observation window device is arranged on the bow of the bionic pressure-resisting device; and a cabin door device is arranged on the tail of the bionic pressure-resisting device. According to the bionic pressure-resisting device, through the scheme that the egg-shaped bionic pressure-resisting shells are connected, the space of a cabin is increased, the man-machine loop characteristics are improved, and meanwhile segmented manufacturing is facilitated; and the scheme that the egg-shaped shells in different sizes are connected is adopted, assembly line light shells are conveniently arranged, fluid resistance of a submersible is reduced, and the fluid dynamic characteristic of the submersible is improved.

Description

technical field [0001] The invention relates to a bionic pressure-resistant device, which belongs to the field of diving equipment. Background technique [0002] Submersibles are important equipment for ocean exploration and deep-sea scientific research. As an important part of submersibles, pressure-resistant equipment 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 weight of the submersible. 1 / 4-1 / 2. The design of pressure-resistant equipment has an important impact on the performance of submersibles such as safety, maneuverability, space utilization and man-machine environment. [0003] Most of the deep-sea pressure-resistant equipment in service is a single spherical structure, and a few are multi-spherical structures, but these structures cannot optimally coordinate the safety, mobility, space utilization and man-machine ring of the submersible. ...

Problems solved by technology

The invention patent with the application number 201510073803.4 proposes a conceptual egg-shaped bionic pressure-resistant shell, which makes it possible to optimize the safety, fluid dynamics, space utilization, and human-machine environment of the submersible. The space is small and cannot meet the requirements of deep-sea pressure-resistant equipment; secondly, the hatch door of the pressure-resistant shell of the invention is connected by simple bolts, which cannot meet the sealing and strength requirements of deep-sea operations; moreover, the pressure-resistant shell of the invention The body does not give the layout of the observation window, such a structure cannot be used in practical applications
