Isolated refuge cabin

Abstract

The present invention relates a refuge used in underground mines, and more particularly to a type of isolated refuge cabin used in underground mines, including the supporting airbag (1), the body shell (2) equipped outside the supporting air bag (1), a breathable air supplier (4) and an air inflation device (3); the air outlet (5) of the air inflation device (3) is linked with an air outlet (7) of the supporting air bag (1) through an air supply passage(6); the air inlet (8) of the breathable air supplier (4) is connected to the interior cavity of the body shell (2) through an air intake passage (9); the air outlet (10) of the breathable air supplier (4) is linked with the lower part of the interior cavity of the body shell (2) through the air outlet passage(11); the breathable air supplier (4) includes a shell (12), the oxygen generating agent (13) equipped inside the shell (12); the emergency exit (14) is installed on the body shell (2). The present invention provides an isolated refuge cabin of a simple structure, which can be operated safely and easily to effectively separate the exterior environment of the mining accident areas and provide conditions for survival for human beings involved in the mine accidents.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a refuge used in underground mines, and more particularly to a type of isolated refuge cabin used in underground mines.BACKGROUND TECHNOLOGY[0002]At present, there has been no existing rescue equipment that can be used to accommodate a large group of people and provide oxygen for over 72 hours in underground mines in China. When an accident occurs in an underground mine, a large amount of the toxic gas is usually generated. The composition of the gas which has toxic effects on humans basically falls into 3 types:[0003]1. Compositions causing asphyxiation or coma;[0004]2. Compositions causing irritation to sensory organs or respiratory system;[0005]3. Other toxic compositions.[0006]From the death toll statistic information of mine accidents, most of the victims died of inhalation of toxic gas such as carbon monoxide.

AI Technical Summary

Benefits of technology

[0007]One of the objectives of the present invention is to provide an isolated-refuge cabin of a simple structure, which can be operated safely and easily to effectively separate the exterior environment of the mining accident areas and provide conditions for survival for human beings involved in the mine accidents.

[0018]Example embodiments of the present invention provide an isolated refuge cabin of a simple structure, which can be operated safely and easily to effectively separate the exterior environment of the mining accident areas and provide conditions for survival for human beings involved in the mine accidents. In emergent circumstance, the air inflation device can be turned on immediately and the supporting air bag will prop up the body shell. The whole system will enter working status immediately. In example embodiments of the present invention, the conversion between carbon dioxide and oxygen can be realized so as to provide conditions for survival for human beings involved in the mine accidents. In order to control the blowing force of the blowing mechanism, a speed control mechanism is installed in the blowing mechanism. In the speed control mechanism, a speed controlling terminal generates torque to the power output shaft based on the rotation speed of the power output shaft based by using the friction between the speed controlling terminal and the speeding controlling sheath. Thus, the blowing force of the blowing mechanism can be effectively controlled.

Problems solved by technology

At present, there has been no existing rescue equipment that can be used to accommodate a large group of people and provide oxygen for over 72 hours in underground mines in China.

When an accident occurs in an underground mine, a large amount of the toxic gas is usually generated.

Due to the block-up or submergence of the mining tunnels, the miners could not flee through the mining passageways and the possibility of their survival is minimal.
