Problems solved by technology

[0003] When a fire breaks out, it is often accompanied by a large amount of smoke. These thick smoke not only hinder breathing, but also block the sight of escape personnel, causing escape personnel to be unable to see the surrounding fire conditions and road conditions, which greatly increases the difficulty of escape. The existing compressed oxygen self-rescuer can only supply oxygen when dangerous situations such as fire occur, and its safety performance is average. Accordingly, this application document proposes a compressed oxygen self-rescuer with high safety performance

Abstract

The invention discloses a compressed oxygen self-rescuer with high safety performance, which comprises a self-rescuer body, an oxygen storage chamber is opened on the side wall of the self-rescuer body, an air bag is fixedly connected to the upper end of the self-rescuer body, and the air bag The upper end is equipped with a breathing mask communicating with the inside, and the lower end of the self-rescuer body is provided with a square groove, and the inner top of the square groove is fixedly connected with a three-way pipe composed of a horizontal pipe and a vertical pipe. An air intake pipe is connected between the oxygen chambers, an air outlet pipe is connected between the horizontal pipe and the air bag, and an exhaust pipe is embedded in the square groove. The present invention sucks the smoke-containing air near the self-rescuer into the vertical pipe and then discharges it from the exhaust pipe. The smoke concentration is low, so that the escaped personnel can clearly see the nearby road conditions and fire conditions, thereby increasing the survival possibility of the escaped personnel.

Description

technical field [0001] The invention relates to the technical field of coal mine safety equipment, in particular to a compressed oxygen self-rescuer with high safety performance. Background technique [0002] When working underground in a coal mine, it is necessary to wear a self-rescuer to escape safely when a dangerous situation occurs, and a compressed oxygen self-rescuer is the most common underground self-rescuer in a coal mine. [0003] When a fire breaks out, it is often accompanied by a large amount of smoke. These thick smoke not only hinder breathing, but also block the sight of escape personnel, causing escape personnel to be unable to see the surrounding fire conditions and road conditions, which greatly increases the difficulty of escape. The existing compressed oxygen self-rescuer can only supply oxygen when dangerous situations such as fire occur, and its safety performance is average. Accordingly, this application document proposes a compressed oxygen self-re...
