Emergency cabin exit fence for manned submersible

Abstract

The invention relates to the technical field of manned submersible, in particular to an emergency cabin exit fence for a manned submersible. The emergency cabin exit fence comprises a supporting frame, a plurality of lining mounting holes are formed in the side face of the supporting frame, and waterproof linings are connected into the lining mounting holes in a glued mode respectively. A plurality of fixing lug plates are arranged on the outer side of the upper end face of the supporting frame, positioning bolt holes are formed in the fixing lug plates respectively, and the positioning bolt holes can be matched with positioning bolts to achieve positioning installation of the emergency exit fence. Under the conditions that the weight of the submersible is not increased and the arrangement of the submersible is not changed, after the submersible floats to the water surface, the submersible can be rapidly and accurately installed in place, the sealing effect is achieved, water pumping is completed through a water pump, a waterless channel is provided for personnel in the cabin to open the hatch cover on the water surface and go out of the cabin, and waves are prevented from being driven into the cabin to damage equipment.

Description

technical field [0001] The invention relates to the technical field of manned submersibles, in particular to an emergency escape fence for a manned submersible. Background technique [0002] Manned submersibles enable human beings to visit the seabed site in person, conduct on-the-spot inspections, sampling, surveying and mapping, search, salvage and other operations, and perform fine seabed operations in complex marine environments. The manned submersible floats back to the surface after completing the diving mission, and needs to be recovered through the A frame of the mother ship. If the A frame fails, the submersible cannot be recovered. When the manned submersible floats to the water surface and the hatch of the manned cabin is below the water surface, the cover cannot be opened to realize the diver’s surface exit. It will cause water to enter the cabin, and it will not be possible for the submersibles to leave the cabin on the surface, so they can only wait for it to...

AI Technical Summary

Problems solved by technology

[0003] At present, there is no such equipment in China. Imported submersibles are equipped with emergency inflatable fences to achieve emergency exit from the water surface. However, the weight of this type of emergency exit device is about 160kg, which will significantly increase the weight of deep-sea manned submersibles and seriously affect the overall performance of the submersible. , at the same time, because the lower flange has both fixing and sealing functions, the larger flange width requires higher space near the access hatch, which is not suitable for deep-sea manned submersibles with compact layout.
