Observation window structure of deep-sea manned submersible with creep mitigation function

Abstract

The invention discloses an observation window structure of a deep-sea manned submersible with a creep mitigation function, and relates to the field of deep-sea manned submersibles. The observation window structure has the advantages that compared with a conventional observation window structure, a hatch cover and a push rod structure are initiatively introduced, combined with electric control of astrain measurement system and hydraulic control system, the thrust acting on an observation window body is generated when an observation window is idle, the high pressure and large deformation causedby the observation window body can be alleviated under the high pressure state of the external seawater during deep-sea operation, the action time of the observation window body under the high-stressstrain is reduced, and the compressive creep of the observation window can be greatly alleviated; the hatch cover can also effectively protect the observation window body, it is avoided that the observation window body is knocked and worn by sundries in a cabin, and the service life of the observation window is prolonged.

Description

technical field [0001] The invention relates to the field of deep-sea manned submersibles, in particular to an observation window structure of the deep-sea manned submersible with the function of slowing creep. Background technique [0002] Deep-sea equipment plays a pivotal role in the development of marine resources. In recent years, my country's deep-sea equipment has made great progress. Among them, the "Jiaolong" and "Deep Sea Warrior" manned submersibles are important representatives of advanced deep-sea equipment and technology. [0003] If a manned submersible is compared to a person, the underwater observation window is equivalent to the eyes of the manned submersible, and it is one of the very important tools for current ocean exploration and research. Under the spot observation. First, scientists can observe the most real deep-sea biological environment through the observation window, which is of great significance to deep-sea scientific research; second, enginee...

AI Technical Summary

Problems solved by technology

[0004] At present, the conventional observation window is made of plexiglass. Compared with metal materials, plexiglass has smaller rigidity, larger deformation, and more serious creep at room temperature. However, the fixed underwater workstation has longer underwater operation time, which will make the observation window The creep problem is more significant, and the creep problem will be directly related to the use of the observation window, and it is far from enough to thicken the observation window only from the design

At the same time, the glass has low hardness and low toughness, and its crack resistance and wear resistance are poor. Therefore, during the use of the observation window, it is also vulnerable to being bumped and worn by debris in the cabin.
