Self-balancing pressure-resistant casing device

Abstract

The invention discloses a self-balancing pressure-resistant casing device, and belongs to the technical field of a bathyscaphe pressure-resistant structure. The self-balancing pressure-resistant casing device is formed by sequentially sleeving and installing a ball-shaped inner casing, a ball-shaped middle casing and a ball-shaped outer casing around the ball center from inside to outside, wherein the ball-shaped inner casing and the ball-shaped middle casing are connected through a pair of symmetrical and coaxial connecting shaft assemblies; the ball-shaped middle casing and the ball-shaped outer casing are connected through a pair of symmetrical and coaxial connecting shaft assemblies; the axial lines of the two pairs of connecting shaft assemblies are mutually vertical, so that the ball-shaped inner casing and the ball-shaped middle casing can mutually rotate, and the ball-shaped middle casing and the ball-shaped outer casing can mutually rotate; each of the two pairs of connecting shafts is provided with a spring damper; the axial impact between the adjacent casings is resisted. The self-balancing pressure-resistant casing device has the advantages that a control system is simplified; the work reliability and the operation stability of a bathyscaphe are improved; the noise is a cabin is reduced; the work environment comfort of aquanauts is improved; the work safety of the bathyscaphe is improved; the material selective range is expanded; the thickness of the casings is reduced; the processing difficulty of the casings is reduced.

Description

technical field [0001] The invention relates to a pressure-resistant structural part of a deep-sea submersible, in particular to a three-layer self-balancing pressure-decreasing pressure-resistant shell device. It belongs to the technical field of submersibles. 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 weight o...

AI Technical Summary

Problems solved by technology

If a conventional single-layer pressure shell is used, it is necessary to use high-strength materials or increase the thickness of the shell, the selection of materials is small, and the processing is difficult

[0006] (3) The deep-sea submersible will generate huge noise during the working process, which seriously interferes with the underwater work of scientific researchers and the normal work of communication devices. The shell needs to have good sound insulation performance

Modern submersibles mostly use composite materials or special-shaped plate and shell structures to reduce noise. However, this sound insulation method can only reduce noise within a certain range, and it is difficult to eliminate or reduce the noise to a lower value.

In order to maintain a constant temperature in the cabin in a low-temperature environment, high-power temperature control devices and insulation materials are often used to maintain a constant temperature in the submersible cabin. However, this constant temperature method requires high performance of the temperature control equipment. Control equipment needs to consume more energy
