Atmospheric working cabin for underwater operation

摘要

An atmospheric working cabin for underwater operation for implementing operations on the underwater object is provided. The working cabin has two or more layers of cabin bodies, each layer of the cabin body has an interface for butting with the underwater object, the interface of the each layer of the cabin bodies is provided with a flexible gel. A space between an innermost cabin body and an outer cabin body is filled with water, after the working cabin butting with the underwater object, the flexible gel is contacted with the surface of the underwater object, water is drawn out successively from the outside to the inside, whilst air is injected therein, an atmospheric pressure is maintained inside the innermost cabin body, the pressure between the cabin bodies is less than the atmospheric pressure and gradually increases from the outside to the inside.

1. An atmospheric working cabin for underwater operation for implementing operations on an underwater object, comprising:
two or more layers of cabin bodies, wherein each layer of cabin body has an interface for butting with the underwater object, the interface of each layer of the cabin bodies is provided with a flexible gel, there is a hollow structure between two adjacent layers of the cabin bodies; wherein the working cabin is filled with water before butting with the underwater object, a space between an innermost cabin body and an outer cabin body adjacent to the innermost cabin body is filled with water, after the working cabin butting with the underwater object, the flexible gel is brought into contact with a surface of the underwater object, water between each layer of cabin body and water inside the innermost cabin body is drawn out successively from the outside to the inside, whilst air is injected therein, an atmospheric pressure is maintained inside the innermost cabin body, pressures between the cabin bodies are less than the atmospheric pressure and gradually increases from the outside to the inside, as there exists a pressure difference between the inside and the outside of the flexible gel of the interface of each layer of cabin body, after the interface contacts tightly with the surface of the underwater object, a sealing between the underwater object and the interface is formed.
