A connection and release device and release method for deep-sea escape cabin

Abstract

A connection and disengagement device and disengagement method for a deep-sea escape cabin, comprising an upper containment well and a lower containment well both of hemispherical structures, the top of the upper containment well is provided with an upper passage enclosure, and the upper passage enclosure is connected to the escape cabin load Human ball, the bottom of the upper enclosure is provided with an upper butt flange; the top of the lower enclosure is provided with a lower butt flange, and the bottom of the lower enclosure is provided with a lower channel enclosure, which is connected to the deep-sea manned submersible. Human cabin; the upper butt flange and the lower butt flange are fixedly connected by explosive bolts, and the flange surface is sealed by a sealing ring; an upper hatch cover is installed inside the upper passage enclosure, and a lower passage enclosure is installed inside the lower passage enclosure. For the lower hatch cover, a normal pressure cavity is formed between the upper well and the lower well under normal conditions; the upper support of the oil cylinder is installed on the inner side under the upper well, and the upper support of the oil cylinder is installed and rotated through the connection pin of the oil cylinder The oil cylinder, the end of the rotary actuating oil cylinder is hinged with the lower support of the oil cylinder; the work is reliable and the use is flexible.

Description

technical field [0001] The invention relates to the technical field of deep-sea release equipment, in particular to a connection and release device and release method for a deep-sea escape cabin. Background technique [0002] The deep-sea manned equipment needs to escape the passage of personnel between the compartments underwater. Especially after an accident, the wrecked personnel can enter a specific cabin (emergency escape cabin) through the personnel passage, and the collective escape of the personnel can be realized after the escape passage. The emergency escape cabin is often equipped on a manned submersible (or submarine). In an emergency, the crew abandons the boat and enters the escape cabin. After being released, it floats to the surface by its own buoyancy for assistance. The escape cabin is usually the last resort for the crew to rescue themselves. A guarantee. [0003] In the prior art, it relates to a connection and release device for an escape cabin. The dev...

AI Technical Summary

Problems solved by technology

[0005] 1. The unlocking method (the jack cylinder pushes the locking ring to unlock) and its driving method are single, and the reliability is lacking;

[0006] 2. During the process of rotating and unlocking, the locking ring may drive the escape pod to rotate together, which will cause the flange of the locking ring to fail to match the groove of the fence, making the escape pod unable to be released and separated, and there are design defects;

[0007] 3. Both the pushing device and the unlocking device are driven by the hydraulic system, the driving method is single, and the reliability is lacking

In summary, the existing escape cabin connection release device has certain defects and low reliability
