The invention discloses a 6000 m-level non-
magnetic pressure-resistant sealed cabin and a manufacturing method thereof, and relates to the field of
deep sea equipment. The 6000 m-level non-
magnetic pressure-resistant sealed cabin comprises a cabin body, the cabin body is provided with a containing cavity used for containing
deep sea detection equipment, the two ends, in the axial direction, of the containing cavity are provided with opening structures used for being connected with sealing end covers in a sealed mode, the cabin body is of a multi-layer
composite structure, and the cabin body sequentially comprises a framework layer, a first composite pressure-bearing layer and a waterproof
protection layer from the interior of the containing cavity to the exterior of the containing cavity; the framework layer, the first composite pressure-bearing layer and the waterproof
protection layer are fixedly connected in sequence, the framework layer has
low permeability, the framework layer is used for supporting the first composite pressure-bearing layer and preventing water in the containing cavity from permeating into the first composite pressure-bearing layer, and the first composite pressure-bearing layer is used for bearing
deep sea water pressure; and the waterproof
protection layer is used for performing waterproof protection on the first composite pressure-bearing layer.
Water tightness and
structural stability of the sealed cabin can be improved, and stable operation of equipment in the sealed cabin is guaranteed.
