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 soft gel, there is a hollow structure between two adjacent layers of the cabin bodies. The working cabin is filled with water before butting with the underwater object, a space between the innermost layer of the cabin body and its adjacent cabin body is filled with water, after the working cabin butting with the underwater object, the soft gel is brought into contacting with the surface of the underwater object, water between each cabin body and the other, in the innermost layer of the 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, the pressure between the cabin bodies is 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 soft gel of the interface of each layer of the 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. Multiple layers of pressure difference sealing are constructed under water by the atmospheric working cabin of the present invention, so as to ensure the working personnel in the cabin safe. |
