A pressure-resistant sealed cabin suitable for underwater sports

Abstract

The invention provides a pressureproof sealed cabin suitable for underwater motions. The pressureproof sealed cabin comprises a plurality of cone-shaped cabin sections and a plurality of columnar cabin sections which are connected in series, wherein an axial sealing structure is formed between one cone-shaped cabin section and another cone-shaped cabin section and a radial sealing structure is formed between each cone-shaped cabin section and each columnar cabin section or between each columnar cabin section and another columnar cabin section. Compared with the prior art, the pressureproof sealed cabin provided by the invention has the advantages that through structural optimization design and sealed design, the pressure-bearing and sealing problems of the pressureproof cabin in a high speed moving process are solved. The ways of axial docking sealing design between the cone-shaped sections as well as the radial sealing designs between the cone-shaped sections and the columnar sections and between the columnar sections are put forward, so that the problem on sealed design of the cone-shaped and columnar sections of the pressureproof cabin is effectively solved.

Description

technical field [0001] The invention relates to the field of underwater devices and sealing devices, in particular to a pressure-resistant sealed cabin suitable for underwater sports. Background technique [0002] At present, the pressure-resistant sealed cabin is generally a sealed cavity assembled from single or multiple column segments. In deep seas or rivers, pressure-resistant sealed cabins are generally in static or slow motion for underwater operations such as ocean exploration and development, scientific research, and underwater weaponry development. With different diving depths and different movement speeds of the pressure chamber, the external environment it withstands is different. Therefore, the pressure chamber needs to withstand the changing external environment and be able to ensure sealing. [0003] At present, most of the existing airtight cabins realize the pressure resistance and sealing functions in the process of static or slow motion. However, when th...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: the existing underwater airtight cabin is generally assembled from a single or multiple column sections, and lacks the connection form of the sealing connection between the cone section and the column section, or between the cone section and the cone section. The connection method between column sections and column sections has problems of insufficient connection accuracy and unreliable sealing design when applied to cone sections
