The invention is further described with reference to the following figures and examples.

Fig. 1 is a three-dimensional schematic view of the present invention;

fig. 2 is an internal schematic view of the present invention;

fig. 3 is a schematic view of the flange cover being connected to the flange of the nacelle.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1, the novel underwater sealing cabin structure of the embodiment includes a cabin body 1 and a flange base 2 arranged at the bottom of the cabin body, the cabin body is connected with a seabed fixing platform through the flange base, 32 bolt through holes are uniformly distributed on the flange base, so that the cabin body and the seabed fixing platform can be conveniently connected and disassembled, and the flange base is simultaneously provided with a limiting guide hole for facilitating alignment of hole sites.

As shown in fig. 1, the outer wall of the cabin body is provided with a plurality of mounting platforms 3, the structural style of the mounting platforms is adapted to the equipment to be mounted, and a plurality of required equipment can be conveniently mounted outside the cabin body through the plurality of mounting platforms. A plurality of hoisting lugs 5 and a plurality of fixed lugs 6 are uniformly arranged on the circumferential direction of the side wall of the cabin body, and the hoisting lugs and the fixed lugs are alternately arranged.
