Description

Chemical self-rescuer under a kind of amphibious mine
Technical field
The utility model relates to a kind of self-rescuer, particularly relates to self-rescuer under a kind of mine.
Background technology
Although at present the safety of mine, tunnel construction and infrastructure engineering is extraordinarily paid attention to, security incident also happens occasionally.As down-hole breaking out of fire, gas explosion or occur flood, particularly on escape route, be obstructed, be trapped in dead face etc., underground work personnel are easy to by water logging, because of anoxic or be subject to harmful gas injury.The self-rescuer using is at present mainly compressed oxygen self-rescuer, and this self-rescuer volume is large, heaviness.Also having a kind of is chemical self-rescuer, and the oxygen generating agent utilization rate of current chemical self-rescuer is not high only has surface course reaction thoroughly, because reaction product is piled up on top layer, causes inner oxygen generating agent to react.In addition, when current chemical self-rescuer runs into flood, do not possess Waterborne self-rescuing function, escape is met difficulty.
Utility model content
The purpose of this utility model, is to provide chemical self-rescuer under a kind of amphibious mine, in the time of there is mine disaster in down-hole, breathes oxygen, wears lightweightly, and has Waterborne self-rescuing function, has improved the self-saving ability of mine disaster.
The technical scheme adopting is:
A chemical self-rescuer under amphibious mine, comprises vest and chemical self-rescuer, it is characterized in that:
Between the internal lining cloth layer of vest and clothing cloth layer, be filled with foamed polystyrene plate, can swim on the water surface after making people wear vest.Before vest, be provided with two medicine bags, the oxygen generating agent of packaging plastic bags is housed in medicine bag.On the back of vest, pocket is set, the oxygen case of chemical self-rescuer is installed and is fixed in pocket.
Described chemical self-rescuer, comprises oxygen case, air bag, appendix mechanism and helmet-type software face shield.Helmet-type software face shield is made by nontoxic plastic material.In oxygen case, be provided with upper spacer and lower clapboard, the below of lower clapboard is return-air chamber, and the top of upper spacer is oxygen room, all has a plurality of holes on upper spacer and lower clapboard.On the upper surface of lower clapboard, be equipped with carbon fiber layer.Between upper spacer and lower clapboard, be filled with mixed type oxygen generating agent.Mixed type oxygen generating agent is by graininess KO 2oxygen generating agent and CO 2absorbent Ca(OH) 2mix and form, KO 2: Ca(OH) 2=2:0.5-1.
Air bag is arranged on the top of oxygen case, and oxygen case is connected with air bag by tube connector, is equiped with flow control valve on tube connector.Air bag is provided with outlet valve.
Gas transmission mechanism, comprises appendix, and insert in air bag the lower end of appendix, and the lower end of appendix is connected with air inlet pipe and muffler by threeway, and muffler is indoor through being inserted into return-air by the muffler jack on oxygen box cover after air bag.Muffler is that tightness is connected with air bag and oxygen box cover.Air inlet pipe is provided with the first non retern valve, and the first non retern valve only allows oxygen to enter appendix.On muffler, be equiped with the second non retern valve, the second non retern valve only allows return-air to leave appendix, enters return-air chamber.When air-breathing by appendix, the first non retern valve is opened, and the second non retern valve is closed, and oxygen supplies by appendix the librarian use of saving oneself.When the personnel of saving oneself feel elated and exultant, the first non retern valve is closed, and the second non retern valve is opened, and the gas of exhalation enters return-air chamber.
Appendix overcoat has bellows-type sheath, and appendix upper end is connected with helmet-type software face shield.Helmet-type software face shield is provided with eyepiece, is positioned at bridge of the nose lower end and is fixed with silica gel spacer body on helmet-type software face shield.
Oxygen case is provided with door, and in case, oxygen-making agent, not during regeneration oxygen, is dosed new mixed type oxygen-making agent by this.
The utility model advantage:
1, the utility model chemistry self-rescuer partial volume is little, lightweight, easy to carry.
2, filling foam benzene plate between the inside and outside layer of cloth of vest part, buoyancy is large.During mine disaster, if any ponding region, wear the vest survivor eminence of can swimming and wait for rescue.
3, the mixed type oxygen-making agent of placing in the oxygen case of chemical self-rescuer part of the present utility model, by KO 2and Ca(OH) 2press KO 2: Ca(OH) 2the mixing ratio preparation of=2:0.5-1.Oxygen generating agent utilization ratio is high, CO 2absorbability is good.
4, adopt helmet-type software face shield, without mouth, hold in the month, and be fixed with eyepiece eyes are had to defencive function.
