Owing to the breathing protection system for mine of the present invention is divided into mouth tool part and oxygen source part, the function of mouth tool part is to constitute the air supply channel closed and reclaim exhaled gas passage, makes people effectively utilize oxygen, and this part variation in each system is little.Mouth tool part also comprises rapid replacing interface top.Oxygen source part comprises rapid replacing interface bottom, rapid replacing interface top and rapid replacing interface bottom adaptation composition have the rapid replacing interface of two gas circuits, when rapid replacing interface separates, two gas circuits of mouth tool part are by self-closed, two gas circuits of oxygen source part are automatically also closing, it is also possible to arrange the function of toxic gas and handoff-security by the structure of rapid replacing interface during being achieved a butt joint with oxygen or fresh air.The breathing protection system for mine of the present invention, owing to the oxygen source part of multiple kinds has identical rapid replacing interface bottom, so the oxygen source part of multiple kinds all can be achieved a butt joint use by rapid replacing interface with same mouth tool part, the switching safely and fast between the various respiratory protection resource under the mines such as self-rescuer, respiratory organ, oxygen cylinder, Inflatable vest, compressed air self-help apparatus can be realized, it is thus possible to overcome the short restriction of the self-rescuer guard time carried with, under comprehensive utilization mine, various oxygen sources are to extend survival time effectively, and raising personnel are rescued chance.The docking standard that described " identical rapid replacing interface " refers to interface is identical, can exchange, and it is identical to be not limited to the aspect such as structure, size.
Oxygen source part can be the fresh air sources such as oxygen cylinder, Chemical Oxygen Source, compressed-air system, it is also possible to was to filter poison device.Thus can be by selecting different oxygen sources, it is combined into a required new respiratory protection system, so personnel just can be on the premise of adorning oneself with a mouth tool part being changed without, reach to utilize the purpose of the oxygen resource being suitable for, eliminate because of original guard system oxygen depletion, the possibility of poison is sucked when using new guard system instead, the most important thing is to make personnel obtain oxygen resource flexibly: time standby, carry with the lightest oxygen source, change when needing distance to flee from that the persistent period is moderate but portable oxygen source, the fixing oxygen source being provided that long duration protection is used when needing to wait assistance.Do so just avoids pursuit and extends the self-rescuer unvanquishable difficulty of guard time, specially to develop some the lightest self-rescuer or oxygen bags on the contrary, protect as long as the of short duration very first time can be competent at.If must wearing during national regulation workman's operation later and there is dustproof filter function, even there is the system necessarily filtering harmful gas function, as long as being so also adopted by identical interface, just such system also can be included in and should call on suction protection system urgently, just reduce further the possibility that personnel are injured by poison.
Perfect along with mine safeguard procedures, colliery to be also extensively equipped with the protective equipments such as compressed-air self-help system, survival capsule, refuge chamber.These facilities also have the part that various protection is breathed, it is provided that fixing oxygen sources.If personnel run away to come here, and can be outside poison isolation, it is possible to take self-rescuer, fallback of taking refuge for a long time.If these facilities are destroyed, existing poison invades, and cannot effectively be protected, would have to take original respiratory organ, use new system instead.If various respiratory protection system used have employed unified quick changing-over interface, it is possible to the devoid of risk realized between each guard system is switched fast, and has widened the usable range of fixing oxygen source.Set up cheap compressed air self-help station more, can be that personnel win more chance for survival.After being helped, it is also possible to switching uses the portability oxygen sources such as self-rescuer again, it is also possible to switching uses the respiratory organ that rescuer brings.After the oxygen resource exhaustion of one or two people, other people can also temporarily lend urgent need person to alleviate emergency situation.Thus can make full use of various oxygen resource neatly, raising personnel are rescued chance.Because the situation that disaster occurs is different, personnel are from occurring mine disaster to successfully fleeing from the state difference that down-hole is experienced.Need to use portable system under the state of fleeing from of running；Need to use long-term oxygen system the period of taking refuge at fallback, it may be possible to the fixation means such as large-scale compression oxygen cylinder or compressed-air self-help system；After fallback terminates the period of taking refuge, although withdraw passage and got through, it would still be possible to the presence of poison, also to change use portable equipment and withdraw mine.
In respiratory protection system provided by the present invention, in addition to the system worn except personnel must be equipped with mouth tool part, other standby systems can be cancelled mouth tool part or only be equipped with the standby of a small amount of mouth tool part, thus reduce expenditure, eliminate the most accordingly and when using instead, take off the step of unwanted mouth tool part in back-up system, shorten the time of process of using instead.

Detailed description of the invention
Below in conjunction with accompanying drawing, the technical scheme in the present invention is conducted further description.Obviously, described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not required to make the most obtainable all other embodiments of creative work, belong to the scope of protection of the invention.
Embodiment one
Breathing protection system for mine, as shown in Figure 1 and Figure 2, has part 1, oxygen source part 2 including mouth；
Described mouth tool part 1, has assembly 10, rapid replacing interface top 30 including mouth；Described oxygen source part 2, including oxygen source assembly 20, rapid replacing interface bottom 31；
Described mouth tool assembly 10, including mouth tool 101, breather cheek valve 103, expiratory one-way valve 102；
Described expiratory one-way valve 102, is arranged in the exhalation passages of described mouth tool assembly 10, and the entrance of described expiratory one-way valve 102 connects with mouth tool 101 or is integrally forming, and outlet connects second gas circuit 302 on described rapid replacing interface top 30；Described expiratory one-way valve 102, opens when personnel 9 are by mouth tool 101 expiration, is connected with exhalation passages by mouth tool 101, and exhaled gas has been put into the return gas channel in oxygen source part 2；
Described breather cheek valve 103 is arranged in the air intake passage of described mouth tool assembly 10；First gas circuit 301 on described rapid replacing interface top 30 connects the arrival end of described breather cheek valve 103, and the port of export connected entrance of described breather cheek valve 103 has or is integral with；When personnel 9 have 101 air-breathing by mouth, described breather cheek valve 103 is opened, and is connected with air intake passage by human oral cavity.
The self-rescuer that the mouth tool 101 contacted with human body oral area can be the most common is used, and mouth of nipping in use is interior and needs nose clip to seal the system in nostril, it is also possible to be the face shield etc. with identity function, but is conveniently collectively referred to as mouth tool to describe.If mouth tool assembly have employed face shield, then mouth tool 101 refers to face shield.
Described rapid replacing interface top 30, including first gas circuit the 301, second gas circuit 302, the first gas circuit 301 connects the air intake passage of described mouth tool assembly 10, and the second gas circuit 302 connects the exhalation passages of described mouth tool assembly 10；Described rapid replacing interface bottom 31, including the 3rd gas circuit the 311, the 4th gas circuit 312；3rd gas circuit 311 connects the air supply channel of described oxygen source assembly 20, and the air supply channel of described oxygen source assembly 20 connects oxygen source 201；4th gas circuit 312 connects the return gas channel of described oxygen source assembly 20.
It is also preferred that the left described source of oxygen 201, it it is the multiple source of oxygen including portable oxygen source；Such as, described source of oxygen 201 can be one of following portable oxygen source: compact oxygen cylinder, small chemical Oxygen Generator, oxygen bag etc., it is also possible to be one of following fixed oxygen source: large-scale compression oxygen cylinder, giant chemical Oxygen Generator etc..Described source of oxygen 201 can even is that provides any system being suitable for the fresh air that people breathes, as fixed air compressed air plant, large-scale compression air bottle, portable or fixed air filtration remove poison device.The abundant washability of oxygen source just so that distress personnel can select to be suitable for the respiratory protection system of situation at that time.If source of oxygen 201 is to provide the device of medical standard oxygen, can be formed by isolation type respiratory protection system, so oxygen source assembly 20 will comprise peace and quiet tank 202, and the gas of backflow reduces carbon dioxide by peace and quiet tank 202, then flow back to air intake passage for recycling.If source of oxygen 201 is to provide the device being available for the air that people breathes, then it is made without removing carbon dioxide to process, owing to outlet valve 102 is generally not entirely without back flow of gas, if so needing exhaled gas to be discharged to air, also will be at one one-way exhaust valve 203 of the exit of gas circuit series connection, so oxygen source assembly 20 will comprise air bleeding valve 203, the gas being back to oxygen source assembly 20 be entered air and guarantee that the air containing toxic component is not sucked by people.
Described rapid replacing interface top 30 is adaptive with described rapid replacing interface bottom 31, collectively constitutes a rapid replacing interface 3；When described rapid replacing interface top 30 separates with described rapid replacing interface bottom 31, as in figure 2 it is shown, described first gas circuit 301 turns off, the second gas circuit 302 turns off, and the 3rd gas 311 tunnel turns off, and the 4th gas circuit 312 turns off；When rapid replacing interface separates, the gas circuit of rapid replacing interface top 30 and rapid replacing interface bottom 31 is all automatically shut off, realize gas circuit seal itself in Renewal process, on the one hand prevent the harmful gas in surrounding air from entering respiration channel, on the other hand oxygen source will not leak waste after rapid replacing interface separates, and inside the 4th gas circuit 312, do not possess generation higher than in the case of ambient pressure, be such as connected with the 4th gas circuit 312 is air bleeding valve 203, also can prevent toxic gas from entering exhaust passage in time.
When described rapid replacing interface top 30 is combined with described rapid replacing interface bottom 31, as shown in Figure 1, first gas circuit 301 on described rapid replacing interface top 30 is connected with the 3rd gas circuit 311 of described rapid replacing interface bottom 31, second gas circuit 302 on described rapid replacing interface top 30 is connected with the 4th gas circuit 312 of described rapid replacing interface bottom 31, and the first gas circuit 301 is connected, second gas circuit 302 is connected, and the 3rd gas circuit 311 is connected, and the 4th gas circuit 312 is connected.So, what just composition one was complete supplies oxygen inhalation system, the mouth tool part in a certain respiratory protection system just can be made to be connected with the oxygen source part of any one of same kind or other kind respiratory protection systems guard system, set up into rapidly new respiratory protection system.
If mouth tool part being moved in the oxygen source part of bottom, as shown in Figure 3, also possible, its shortcoming is under normal operating condition, and the distance of mouth to breather valve is big, and the effciency of respiratory of people reduces, carbon dioxide treatment efficiency also reduces, if oxygen source fixing with compressed-air system etc docks use and also needs separately to set many breathing air valves, it has not been convenient to, and breathe air valve and can be readily integrated in mouth tool.If being further evolved into state described in Fig. 4, then bring the interests simplifying rapid replacing interface, only need a gas circuit, but the shortcoming of Aforesaid deformation scheme all possesses, and because the gas of exhalation can not be separated with live gas, the burden of carbon dioxide treatment can be increased the weight of further, after interface 3 disconnects, be less useful for being formed the mini system of a self-loopa as shown in Figure 5.
Embodiment two
Based on embodiment one, system increases an air bag 104.The effect of air bag is accumulation part of oxygen, in case consuming during changing-over oxygen source, reduces the time pressure of personnel's Renewal process, also buffers the pressure change caused because of supply speed inequality.Described air bag 104 is arranged in the air intake passage of described mouth tool assembly 10, as shown in Figure 5；First gas circuit 301 on described rapid replacing interface top 30 connects one end air flue of described air bag 104, and the other end of described air bag 104 connects the arrival end of described breather cheek valve 103, and the port of export connected entrance of described breather cheek valve 103 has or is integral with；When personnel 9 have 101 air-breathing by mouth, described breather cheek valve 103 is opened, and is connected with air intake passage by human oral cavity.
It is also preferred that the left a relief valve 106 can also be increased, it is contained in described air bag or air intake passage or exhalation passages, as shown in Figure 5.Relief valve 106 is the check valve automatically turning on aerofluxus when respiration channel air pressure is higher than setting threshold value, is possible to prevent because of the phenomenon of compressed gas source discharge capacity excessive obstruction eupnea.
Preferably, if having combined the air bag 104 with a constant volume in mouth tool assembly, one interim gas circuit 3029 just can be set between air intake passage and exhalation passages, it is located in place of rapid replacing interface top 30, when rapid replacing interface 3 combines, this interim gas circuit disconnects, and when described rapid replacing interface top 30 separates with described rapid replacing interface bottom 31,3029 exhalation passages of interim gas circuit are connected with air intake passage；So, mouth is made to have part 1 from becoming a little gas-circulating system, it is possible to maintaining the breathing of short time by the oxygen gas component of storage in consumption air bag 104 more swimmingly during changing oxygen source, the urgent degree allowing for Renewal process reduces, it is simple to use.If being not provided with this interim gas circuit 3029, the smoothness that personnel now breathe can be weaker, permitted gas space between inlet valve, outlet valve and oral cavity three will be done bigger, and efficiency when so can breathe human normal has an impact, be equivalent to reduce respiratory depth, because the gas of a part of gas the sucked last exhalation that to be carbonated high.This interim gas circuit 3029 can have multiple implementation method, it might even be possible to is integrated among rapid replacing interface top 301.This point is further explained in the scheme of rapid replacing interface.
This interim gas circuit can manually Valve controlling break-make, as shown in Figure 6, it is possible to as shown in Fig. 7, Figure 16 by and the Valve controlling break-make of rapid replacing interface 3 linkage, it is also possible to as shown in Figure 8, be integrated in air bag with check valve form.In fig. 8, the pressure reduction as inlet valve 103, the check valve breakdown action of outlet valve 102 use is the lowest, and the pressure reduction that the eupnea of people causes gets final product folding；Starting differential pressure as the check valve of interim gas circuit 3029 use is moderate, after described rapid replacing interface 3 disconnects, the Repiration of people is constantly pumped into the gas in air bag in exhalation passages, strengthen pressure reduction, pressure reduction after reaching a higher thresholds interim gas circuit 3029 open, it is achieved that the gas circulation shown in dotted line.The advantage of the program is simple in construction, it is easy to be integrated in air bag, and shortcoming is that the breathing of people to be needed to strengthen exerting oneself of breathing by certain resistance, not as using mechanism to set up interim gas circuit 3029.Air bleeding valve needs higher inside and outside differential pressure effect to open, and does not affect inlet valve, outlet valve, the action of check valve as interim gas circuit, therefore can set up the autologous circulation of closing in air bag.
Embodiment three
Based on embodiment one, when described rapid replacing interface top 30 is combined with described rapid replacing interface bottom 31, first the 3rd gas circuit 311 is connected, and the 4th gas circuit 312 is then turn on, and first gas circuit the 301, second gas circuit 302 is finally connected；When described rapid replacing interface top 30 separates with described rapid replacing interface bottom 31, first first gas circuit the 301, second gas circuit 302 turns off, and the 3rd gas circuit the 311, the 4th gas circuit 312 is then powered off；
In this embodiment, due to when rapid replacing interface separates, rapid replacing interface top 30 gas circuit turns off prior to rapid replacing interface bottom 31, due to when rapid replacing interface combines, rapid replacing interface top 30 gas circuit is later than rapid replacing interface bottom 31 and connects, the more anticyclonic oxygen rich gas of rapid replacing interface bottom 31 ejection can arrange the poison around interface, prevents harmful gas respiration channel of inlet port tool assembly during changing-over oxygen source part, further increases the safety that oxygen source is changed.
The rapid replacing interface top 30 of adaptive composition rapid replacing interface 3 and rapid replacing interface bottom 31, can be as it is shown in figure 9, coaxially arranged two gas circuits, i.e. ectonexine be respectively arranged a gas circuit respectively, it is easy to quick-replaceable operates；Can also use and there is being arranged in juxtaposition of Anti-error structure as shown in Figure 10, design relatively independent passage the most side by side, but be also the most overall grafting；Can also use, as shown in Figure 11, Figure 12, Figure 13, the mode that the two-way with avoiding misinsertion function separates, this can be favourable with the simplification of docking port, but needs twice grafting just can complete to change oxygen source operation.
Embodiment four
Based on embodiment one, such as Figure 14, the oxygen source assembly 20 in described oxygen source part 2 includes air bleeding valve 203, source of oxygen 201, and here source of oxygen 201 is compressed-air self-help system, it is provided that the fresh air that pressure is suitable for；This situation is that miner provides the long duration protection means being easily achieved, be prone to extensively lay website.
The 4th gas circuit 312 in described rapid replacing interface bottom 31 is connected with described air bleeding valve 203, and when the air pressure caused because of people's expiration in the return gas channel of oxygen source assembly 20 is higher than setting threshold values, described air bleeding valve 203 automatically turns on, and is directly discharged into air breathing waste gas.
If source of oxygen 201 changed into filters poison device, as shown in figure 15, then just become the lightest carry-on guard system.As long as the material filtering poison is reliable, even being only capable of ten a few minutes that normally worked, also the biggest daily burden can be alleviated to workman.If it is higher to the degree of protection of miner from now on; have developed the dustproof filter function must worn at any time in down-hole; even there is the air purifier equipment necessarily filtering harmful gas function; this system can be included in this respiratory protection system; protection system is just made more to optimize; even if this new guard system does not have the function of gas defence, workman still needs to wear oxygen source of saving oneself, it is also possible to saves for saving oneself and opens the time that mouth tool is worn when disaster occurs.In this new guard system, the mouth tool 2003 with human contact preferably uses face shield form.Face shield is higher than the mouth tool comfort level stung in mouth, owing to wearing always, can shorten the time wearing self-rescuer, just reduce further the possibility that personnel are injured by poison.At this moment personnel want the oxygen source part that other body-worn one is light standby.
