Automatic oxygen generator

Abstract

The invention relates to an automatic oxygen generator comprising a near-cylindrical nonmetallic vessel, wherein the nonmetallic vessel comprises an opening and a bottom arranged at the other side relative to the opening, and hydrogen peroxide is contained in the nonmetallic vessel; a barrier is arranged in the nonmetallic vessel and can prevent the nonmetallic vessel from being in contact with the hydrogen peroxide even in case of inclination; the barrier comprises a fixed plate and a movable plate, the movable plate can rotate around the shaft, one part of the movable plate is superposed onthe fixed plate, and a gap is formed between the other part of the movable plate and the fixed plate; the inner wall of the nonmetallic vessel is provided with a spline, the movable plate is providedwith a shifting block which extends out of the inner wall of the nonmetallic vessel, and a catalyst matched with the quantitative response of the hydrogen peroxide is arranged on the fixed plate; anda sealing cover for sealing the entire nonmetallic vessel is arranged at the opening of the nonmetallic vessel. The invention has the advantages of simple structure, high security and low cost, and is suitable for personnel working in any high-risk environment such as a downhole environment.

Description

technical field [0001] The invention relates to an oxygen generator, in particular to an automatic oxygen generator. Background technique [0002] At present, people who have accidents in coal mines every year in our country happen from time to time. When a mining accident occurs, it is imperative to rescue the trapped workers with all their strength. [0003] After the mining accident, due to the influence of the existing rescue equipment and technology, the rescue process cannot be very short, and the trapped people died of asphyxiation because they did not breathe oxygen in time, which accounted for a large proportion. loss of people's lives and property. At present, the actual operation is to quickly open a pipeline and use the oxygen tube to deliver oxygen to the trapped people underground to win the rescue time, but even this will take a considerable amount of time, and the constraints of the environment are relatively large. Generally speaking: at present Also do n...

Problems solved by technology

[0003] After the mining accident, due to the influence of the existing rescue equipment and technology, the rescue process cannot be very short, and the trapped people died of asphyxiation because they did not breathe oxygen in time, which accounted for a large proportion. loss of life and property

At present, the actual operation is to quickly open a pipeline and use the oxygen tube to deliver oxygen to the trapped people underground to win the rescue time, but even this will take a considerable amount of time, and the constraints of the environment are relatively large. Generally speaking: at present There is no simple oxygen supply equipment specially equipped for workers
