Emergency escape system of saturated diving system

Abstract

The invention provides an emergency escape system of a saturated diving system. The emergency escape system comprises a diving bell, a diving bell connecting pipe, a diving bell transfer cabin, an escape elbow, a 90-degree escape elbow, a high-pressure lifeboat connecting pipe, a high-pressure lifeboat and the like which are connected in sequence. The diving bell connecting pipe and the escape bent pipe are each provided with a branch, an escape communication cabin is arranged between the diving bell connecting pipe and the escape bent pipe, and a first port and a second port of the escape communication cabin are connected with the branches on the diving bell connecting pipe and the escape bent pipe respectively. An escape communication cabin air-tight door is arranged at a second port ofthe escape communication cabin, and an air pressure balance valve is arranged on the escape communication cabin air-tight door. According to the system, the on-site installation precision requirementcan be met, the escape path is effectively shortened, the escape difficulty is reduced, and the escape time is reduced. In emergency, the escape time 1-2 minutes for a diver can be obtained.

Description

technical field [0001] The invention relates to an emergency escape system for a saturation diving system. Background technique [0002] Saturation diving support The saturation diving system fixedly installed on board is a diving system used to support divers in long-term operations at large depths. During the saturation diving operation in deep water, divers need to activate the emergency escape device for divers in case of unexpected accidents on the mother ship, such as ship fire, hull collision and shipwreck and other dangerous situations. At this time, the diver has no time to return to the decompression chamber for decompression. It is necessary to enter the diving bell from underwater urgently, and the diving bell recovery system will recover the diving bell to the ship. The divers will pass through the diving bell, the diving bell connecting pipe, the diving bell transfer cabin, the escape bend, the 90° escape bend, and the high-pressure lifeboat connecting pipe in...
