Emergency rapid inflated life-raft

Abstract

The invention relates to an emergency rapid inflated life-raft. According to the invention, at least two air generators are arranged in the emergency rapid inflated life-raft, several air generators are connected with power supply in parallel through leads, and multiple-point switches are arranged between the air generators and the power supply. Several air generators daily used for air bag in a vehicle are preset in the inflated life-raft, through control by the multiple-point switches, inflation with enough air amount can be guaranteed, the recoil strength is reduced, people safety can be guaranteed; when used as standby, the inflated life-raft is folded for storage without space occupation; while in use, the inflated life-raft is inflated instantly, and has the advantages of safety and rapidity.

Description

technical field [0001] The invention relates to a life raft, in particular to a life raft that can be rapidly inflated multiple times. Background technique [0002] On almost all passenger ships (especially large cruise ships), the number of life rafts is seriously insufficient. Once an accident occurs, many people are often unable to evacuate safely. After observation and understanding, I found that the reason for this phenomenon is that, on the one hand, ordinary life rafts take up too much space, and on the other hand, no matter the size of the ship, the usable space is very limited. The three reasons are that the accident is a small probability event after all, resulting in a very low actual utilization rate of life rafts. Under the influence of these three factors, people tend to be lucky, so the number of life rafts on board is seriously insufficient relative to the actual number of passengers on board. [0003] The invention utilizes the principle of instantaneous i...

Problems solved by technology

[0004] Among the various inflatable raft products and patents that can be found at present, some focus on the safety design of the boat body and do not involve the inflation method; some use external inflatable equipment, which is not comparable; some use built-in dry ice To realize the inflation function, the efficiency, safety and feasibility cannot be compared with this research
