Abstract
The utility model relates to the technical field of lifesaving and discloses an underground portable refuge device which comprises: an oxygen unit, an air bottle filled with compressed air and a cabin body formed by inflatable double protection layers and used for refuge. The air bottle is communicated with the double protection layers through a valve and a pipeline and the oxygen unit is arranged in or communicated to the inner part of the cabin body.
Description
Technical field
The utility model relates to the lifesaving technology field, relates in particular to a kind of downhole portable refuge apparatus.
Background technology
After fire is blasted in the down-hole, mine, can produce toxic and harmful, threaten personnel in the pit's life security.At present, the mine personnel self-help apparatus has only breather and chamber, and breather can only singlely use, and oxygen supply time is short; Chamber fixed-site and limited amount have with a certain distance from the personnel in the pit job site.When accident took place, the personnel in the pit can not in time withdraw and be exposed in the toxic and harmful threat to life safety.
Summary of the invention
The object of the present invention is to provide a kind of downhole portable escape device, it can provide oxygen to distress personnel after fire is blasted in the down-hole, mine, isolates pernicious gas.
In order to achieve the above object, the present invention gives realization by the following technical solutions: a kind of downhole portable refuge apparatus, it is characterized in that, comprise: oxygen cell, be filled with Compressed Gas gas cylinder and by inflatable pair of overcoat form be used to take refuge the cabin body, described gas cylinder is by valve and the two overcoats of pipeline connection, and described oxygen cell places or be communicated to body inside, cabin.
Further characteristics of the present utility model are:
Described Compressed Gas is air or nitrogen.
The skin of described pair of overcoat is the fire-proof and thermal-insulation composite material, and interior overcoat is the PVC coated fabric.
Described oxygen cell is oxygen storage unit or spontaneous oxygen cell.
Its further characteristics be:
Described oxygen storage unit is the storage oxygen cylinder.
Described spontaneous oxygen unit is the oxygen candle.
Described spontaneous oxygen unit is to store the peroxide of alkali metal or alkaline-earth metal or the container of superoxides.
The utlity model has tangible beneficial effect.After fire incident is blasted in the down-hole, mine, distress personnel can be opened the gas cylinder of compressed air suits rapidly, prop up two overcoats, the cabin body that formation is taken refuge, oxygen cell is placed or is communicated in the body of cabin simultaneously, constantly supplemental oxygen in the body of cabin is protected institute for distress personnel provides a safety to keep away.This refuge apparatus foldable for storage, have in light weight, volume is little, single carrying, no energy consumption does not take drive and work plane space.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further details.
Fig. 1 is the user mode schematic diagram of a kind of downhole portable refuge apparatus of the present utility model.
Fig. 2 is the folded state schematic diagram of downhole portable refuge apparatus shown in Figure 1.
Among the figure: 1, gas cylinder; 2, bottle valve; 3, pressure reducer; 4, pressure meter; 5, air supply pipe; 6, safety valve; 7, advance vent valve; 8, cabin body; 9, wide angle viewing mirror; 10, fire-proof and thermal-insulation composite material; 11, PVC coated fabric; 12, spontaneous oxygen unit; 13, scavenge trunk; 14, hatch door.
The specific embodiment
In Fig. 1, bottle valve (2) is installed on the gas cylinder (1), and pressure reducer (3) is connecting pressure meter (4) and air supply pipe (5), and the other end of air supply pipe (5) is connected with safety valve (6), into vent valve (7) is arranged on the cabin body (8), advance vent valve (7) and link to each other with safety valve (6).Open bottle valve (2) during use, the air of the compression in the gas cylinder (1) or nitrogen are by pressure reducer (3) decompression, when pressure meter (4) reached the certain pressure value, open the safety-valve (6) formed cabin body (8), closed safe valve (6) after cabin body (8) is propped up for two overcoat inflations.
Oxygen cell in the present embodiment is spontaneous oxygen unit (12), for the peroxide that stores alkali metal or alkaline-earth metal or the container of superoxides, specifically stores Na
2O
2Spontaneous oxygen unit (12) is communicated in the cabin body (8) by scavenge trunk (13).The interior protection coating materials of cabin body (8) is a thickening PVC coated fabric (11), and the external protection coating material is fire-proof and thermal-insulation composite material (10), and two overcoats of cabin body (8) are provided with wide angle viewing mirror (9) and hatch door (14).
After cabin body (8) is propped up expansion, open scavenge trunk (13), start spontaneous oxygen unit (12), oxygen and absorbing carbon dioxide gas are provided for cabin body (8), concrete chemical reaction mode is:
Na
2O
2+H
2O→NaOH+O
2
Na
2O
2+CO
2→Na
2CO
3+O
2
Certainly, spontaneous oxygen unit (12) also can adopt the oxygen candle, be self-contained Oxygen Generator (self-containedoxygen generator), for example: the oxygen candle that Australia big sharp Molecular company produces, be not subjected to the interference of ambient temperature and pressure after its operation, the time release total amount that can continue about 25min is the oxygen of 720L.
The simplest method is: oxygen cell is an oxygen storage unit, adopts the storage oxygen cylinder.The storage oxygen cylinder is filled with compressed oxygen, can directly be placed on cabin body (8), uses jointly for distress personnel.
Claims (7)
