Hatch emergency inflation fence for manned submersible

Abstract

The invention provides a hatch emergency inflation fence for a manned submersible. The hatch emergency inflation fence is installed on a bathyscaphe and connected with the manned submersible. The hatch emergency inflation fence is characterized by comprising an inflation fence body arranged on the manned submersible, an inflation electromagnetic valve installed on one side of the inflation fence body, an electromagnetic valve control panel arranged in a manned submersible diving chamber and connected with the inflation electromagnetic valve to control the inflation electromagnetic valve, a high-pressure air pipe arranged in the manned submersible diving chamber, a control valve installed on the high-pressure air pipe and used for controlling on and off of the high-pressure air pipe in the chamber, and a high-pressure air tank communicating with the other end of the high-pressure air pipe, wherein one end of the high-pressure air pipe communicates with the inflation electromagnetic valve; when the inflation electromagnetic valve and the control valve are closed, the inflation fence body in a flat state is fixed into a fence base; and when the inflation electromagnetic valve is opened, the high-pressure air pipe is opened by opening the control valve, and the inflation fence body is inflated.

Description

technical field [0001] The invention relates to an emergency inflating device, in particular to an emergency inflatable fence for providing an extra hatch freeboard when a hatch of a manned submersible is emergency opened on the water surface. Background technique [0002] When the manned submersible works under normal working conditions, the submersible is put into the water, and when the submersible completes the dive and rises to the surface, there will always be a process of the submersible floating on the water surface waiting to be unhooked or hooked. During this process, the waterline of the submersible can reach The distance between the tops of the bulkheads of the opened hatches is generally less than 750mm required by the Classification Society. Because the submersible is located in the cabin, there will be no opening of the hatch, and only part of the submersible needs to be exposed to the water surface for hooking or unhooking. [0003] Under emergency condition...

Problems solved by technology

For example, the Alvin manned submersible in the United States is equipped with a fixed fiberglass superstructure to surround the hatch. The bulge formed by such a superstructure will occupy the layout space of the submersible and affect the streamlined hydrodynamic shape of the submersible.
