Description

Isolated escape system

Technical field

The invention belongs to underground mining industry shelter and lifesaving apparatus field, relate in particular to a kind of mine and use isolated escape system.

Background technology

At present, domestic still do not have can hold many people, the continuous special-purpose mine refuge lifesaving appliance of oxygen supply more than 72 hours, if in the mine in case mine disaster takes place, tend to produce a large amount of toxic gases.Have the gas product of concrete poisonous effect can be divided three classes basically to Human Physiology:

1, asphyxiating or stupor property composition;

2, to sense organ or respiratory apparatus composition excitatory;

3, other undue toxicity composition;

See that from most of mine disaster necrology data most of victim causes death because of sucking unwanted combustion gases such as carbon monoxide.Because prospect tunnel is blocked or is submerged, the miner can't be through the escape of mining passage, and its existence is hoped very remote, and this also is many main causes of China mine disaster casualties personnel.Still there is not the escape system of recovering and matching in the prior art with above-mentioned mine disaster.

Summary of the invention

The present invention is intended to overcome the weak point of prior art and provides simple in structure, and handling safety, convenience can effectively completely cut off the external environment condition of mine disaster generation area when mine disaster takes place, satisfy the isolated escape system of corresponding human body life condition in the refuge chamber.

For achieving the above object, the present invention is achieved in that

A kind of isolated escape system, it comprises support air bag, is assigned in the outer wall body of said support air bag, breathes and supply with body and aerating device; The inflation outlet of said aerating device is joined through the inflation inlet of aspirating pipeline and support air bag; Exhalation vents and the air entry that body is supplied with in said breathing joins with the face shield exhalation vents and the face shield air entry of the breathing mask that is positioned at wall body respectively successively; Said breathing is supplied with body and is comprised housing, is assigned in the oxygen-making agent in the housing; On said wall body, are furnished with escape.

As a kind of preferred version, be provided with filter cylinder in the housing of breathing supply body according to the invention; Form the cylindricality cavity between the outer wall of said filter cylinder and the inwall of housing; Is furnished with oxygen-making agent in the said filter cylinder; Said exhalation vents communicates with cavity; Said air entry communicates with the inner chamber of filter cylinder; The sidewall of said filter cylinder is furnished with micropore.

As another kind of preferred version, supply with the external heat sink assembly of fixedly being furnished with in said breathing.

In addition, the present invention can be fixed with safety valve on said support air bag.

The present invention can be provided with breather cheek valve in said inflation entrance.

The sidewall of filter cylinder according to the invention can adopt ripple struction.

The present invention is furnished with adjuster on said wall body; The toxic gas filtering agent is housed in the said adjuster; On said adjuster, be provided with the outside port and the wall body port that communicate with the toxic gas filtering agent respectively; Said wall body port communicates with the inner chamber of wall body.

The present invention also can be furnished with gasing tank in said wall body; The quick release valve pulling plug and the support air bag of said gasing tank are affixed.

The present invention is simple in structure, and handling safety, convenience can effectively completely cut off the external environment condition of mine disaster generation area when mine disaster takes place, can provide human body corresponding life condition in the refuge chamber.The present invention under normal circumstances, each several part can be integrated in the packing, in case emergency takes place, can open aerating device rapidly, support air bag is propped up with being about to wall body, whole system moment gets into duty.The present invention can realize the alternating permutation of carbon dioxide and oxygen through breathing the supply body, thereby has guaranteed the normal of the interior basic Signs of underground operators life of wall body, finally tries to gain time precious to one for the mine disaster relief.
