Underground self-rescue device of coal mine

Abstract

The invention provides an underground self-rescue device of a coal mine. The device comprises a clothes type inflatable floating body and an air bag, wherein the air bag is connected to the floating body; the floating body is not communicated with the air bag; the air bag is connected with a vent pipe; a sodium peroxide medicine bag and a spring cushion are placed in the air bag; the sodium peroxide medicine bag is filled with net yarns; and the spring cushion is formed by connecting springs. The underground self-rescue device of the coal mine provided by the invention is small in volume and can prevent a person from being drowned, asphyxiated and poisoned by gas. When operating underground, a miner can carry the self-rescue device; once an accident occurs, air and oxygen are respectively filled into the floating body and the air bag immediately; the floating body which is filled with the air generates a certain buoyant force, and the air bag which is filled with the oxygen supplies the oxygen to the person so as to prevent the person from being poisoned by the gas; meanwhile, the air bag serves as an oxygen regeneration device, receives carbon dioxide which is generated by breathing of the person by using a chemical agent, discharges the oxygen and maintains the longer-time breathing of the person; and the spring cushion in the air bag is sprung to support the air bag, so the person cannot have a sense of pressure when breathing in water.

Description

technical field [0001] The invention relates to the field of coal mine lifesaving, in particular to an underground coal mine self-rescue device. Background technique [0002] Coal mining enterprises often have underground accidents, such as collapses and gas explosions, causing water ingress and toxic gases in the tunnels, making the life safety of miners unable to be guaranteed. Equipping underground self-rescue devices can help save precious lives and buy time for rescue. [0003] The use of life jackets can be used after the roadway is flooded to prevent miners from being submerged in water. However, after the roadway is flooded, it will usually be accompanied by gas gushing out. Most of the roadway is submerged, and the breathing space is greatly reduced and filled with gas. Death by drowning, suffocation or gas poisoning. The use of gas masks can solve the problem of gas poisoning, but it cannot solve the problem of personnel drowning and oxygen supply after the flood ...

AI Technical Summary

Problems solved by technology

However, the number of rescue cabins arranged underground is limited and the positions are fixed. After a water seepage or gas outburst accident occurs underground, the personnel may be located far away from the rescue cabins and cannot enter the rescue cabins in time.
