Liquid oxygen filling and recovery system for underwater working platform

Abstract

The invention discloses a liquid oxygen injection and recycle system of an underwater working platform. The liquid oxygen injection and recycle system comprises a pipeline system arranged on a water mother ship, a pipeline system arranged on an underwater working platform and a connection unit connecting the two pipeline systems, wherein the pipeline system on the water mother ship comprises a liquid oxygen injection pipeline unit and an air blowing-off pipeline unit; the pipeline system on the underwater working platform comprises a liquid oxygen storage cylinder which is provided with a supplying-in pipeline and a emission pipeline, and a by-pass pipeline is arranged between the supplying-in pipeline and the emission pipeline; the connection unit comprises an injection tube and a gas emission tube which are used for being connected with liquid oxygen storage and recycle equipment on the water mother ship and the inlet and outlet of the liquid oxygen storage cylinder on the underwater working platform; liquid oxygen supplying is realized through the liquid oxygen injection pipeline unit, the injection tube and the supplying-in pipeline; air is blown off through the air blowing-of pipeline unit, the injection tube, the by-pass pipeline, the gas emission tube and a gas emission pipeline; and the liquid oxygen is recycled through the air blowing-off pipeline unit, the injection tube, the by-pass pipeline, the gas emission tube and a recycle pipeline. By adopting the liquid oxygen injection and recycle system, the liquid oxygen can be safely and efficiently provided to the underwater working platform and recycled.

Description

technical field [0001] The invention relates to the technical field of underwater work platform protection, in particular to a liquid oxygen filling and recovery system for an underwater work platform. Background technique [0002] In recent years, fuel cell technology has developed rapidly. Its high efficiency, energy saving, and good environmental performance close to zero emissions have made it a hot spot in the development of energy and transportation in the world today, and it has been compared in many fields such as electric vehicles, aerospace, and underwater equipment. Wide range of applications. Based on the fuel cell as an underwater power system, it can obtain outstanding advantages such as long battery life, low noise, and weak infrared signal. More and more underwater equipment (such as submarines, UUVs, underwater work platforms, etc.) will use fuel cells as power One of the preferred schemes of the system. As far as the current domestic and foreign fuel cell...

Problems solved by technology

For some underwater working platforms with a small load tonnage, due to space constraints and operating function requirements, it is impossible to provide oxygen-generating equipment on the platform. The outstanding feature is special operations in small areas and small areas, and its endurance is inherently small. If the underwater working platform frequently goes back and forth between the port and the operating area for replenishment, its operating capacity and operating efficiency will be greatly reduced

Therefore, the first two commonly used liquid oxygen supply methods are not suitable for small underwater working platforms
