Accompanying drawing explanation
Above-mentioned is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, below in conjunction with accompanying drawing, the utility model is described in further detail with detailed description of the invention.
Fig. 1 is this utility model fire-fighting structure sectional view with guard shield of saving oneself.
Fig. 2 is the principle schematic of Smoke Sensor in this utility model.
Detailed description of the invention
With reference to shown in accompanying drawing 1, this utility model fire-fighting includes head-shield 2 and the turnover gas controlling organization being connected with this head-shield 2 with guard shield of saving oneself.
This head-shield 2 is for entangling the head entirety of wearer, it is simple to protect its hair and skin of face.The front side of this head-shield 2 is provided with sight glass 1, is used for protecting eyes and providing sight line.The lower openings place of this head-shield 2 is provided with contractile flexible rubber ring 3, and this flexible rubber ring 3 makes this head-shield 2 have seal and be easy to the wearing of this head-shield.Owing to this head-shield 2 has seal, storing a certain amount of air, this air being full of at least can for wearer five minutes, it is simple to the personnel of wearing flee danger region.The more excellent employing transparent flame-retarding material of this head-shield 2, is beneficial to fire prevention, such as silica gel.Silica gel is flexible material, collapsible, is convenient for carrying.
In order to protect the throat of wearer further, this head-shield 2 also includes throat's screening glass 4, and throat's screening glass 4 is arranged at the front side of flexible rubber ring 3, for protecting its throat when wearer wears.All using the sight glass side of guard shield of saving oneself for front side with this fire-fighting in the application, its opposite side is rear side, and this statement, only for describing conveniently, should not be understood as any restriction to this application.
This turnover gas controlling organization includes the airway 5 connected with head-shield 2, the terminal valve 7 being arranged on airway 5, Smoke Sensor 8 and electrical pump 9 and the battery 11 for Smoke Sensor 8 and electrical pump 9 power supply.
This airway 5 is tee T, and its first port is internal with head-shield 2 to be connected, and its second port is air vent 6, and its 3rd port is air inlet 12.This terminal valve 7 is arranged at the intersection of this tee T, including controlling the air intake valve of air inlet 12 air inlet and controlling the drain tap of air vent 6 aerofluxus.This Smoke Sensor 8 and electrical pump 9 are successively set on air intake valve to the airway 5 between air inlet 12.This built-in miniature motor of electrical pump 9, this miniature motor is powered by battery 11, drives electrical pump 9 to pump into inside head-shield by extraneous air, for head-shield 2 inner inflatable.
This Smoke Sensor 8 is the flue gas analysis spectrum sensor based on acousto-optic tunable filtering, and it can measure CO, CO in flue gas2、C2H6、CH4、NO、NO2、H2The content of the toxic and harmfuls such as O.This flue gas analysis spectrum sensor adopts absorption spectroscopy techniques, and radiation source used is infrared or ultraviolet spectra, and the absorption of radiation is determined the content of various gas by various gases contained in measurement flue gas.As shown in Figure 2, from the infrared ray of the source of infrared radiation respectively through two gas elements, one is reference element, and another is sampling element.What fill in reference element is dry nitrogen, does not absorb infra-red radiation, and when infrared ray is by sampling element, flue gas molecule will absorb some infra-red radiations.Therefore, from sampling element, the infra-red intensity of injection is less than incident intensity, certainly again smaller than the infra-red intensity of injection from reference element.The detector to specific infrared wavelength is sensitive is utilized to detect sensitive infrared intensity difference, thus recording toxic and harmful content in flue gas.
This turnover gas controlling organization also includes a control box, and this terminal valve 7, Smoke Sensor 8, electrical pump 9 and battery 11 may be contained within this control box.Battery 11 is the motor power supplying within sensor 8, electrical pump 9 and electrical pump 9, and this battery 11 is for ease of the Li-Ion rechargeable battery of dismounting, repeatable utilization, energy-conserving and environment-protective.
In order to fix this fire-fighting guard shield of saving oneself further, it is additionally provided with folder neck device 10 outside this control box, for this control box being fixed on the collar of wearer.
This utility model fire-fighting guard shield of saving oneself uses when there are the dangerous situations such as fire, wearer realizes this head-shield 2 is covered in wearer's head and sealed by the stretchable effect of flexible rubber ring 3, now open miniature motor, motor driving electrical pump 9 runs, extraneous gas is made to enter from air inlet 12, drive air valve into by Smoke Sensor 8 backlash and enter head-shield 2 inside, until the gas in head-shield 2 is sufficient, when head-shield internal gas pressure is more than external pressure, the drain tap at air vent 6 place is rushed to open, and in head-shield 2, excessive gas is discharged by air vent 6.When Smoke Sensor 8 detects toxic and harmful content beyond predetermined value, control the air intake valve within box and drain tap is automatically switched off, motor quits work simultaneously, such head-shield 2 internal memory contains a certain amount of air, keep head-shield internal pressure, prevent toxic gas from entering face shield, it is simple to wearer utilizes this certain amount of air of storage in this head-shield 2 to flee danger region, is saved oneself.When external environment condition is recovered after normally, electrical pump 9 can be again started up, and recovers normal air-suction state, inflates for head-shield.
This utility model fire-fighting is mainly used in the daily routines places such as hotel, office building, market, place of public amusement and house with guard shield of saving oneself.When accident occurs, save oneself for personnel and escape is worn, when flue gas, poison do not spread, air is pressed in head-shield, once detect that toxic and harmful exists, closing head-shield, the tolerance being full of in head-shield at least can provide the tolerance of 5 minutes, it is easy to personnel and flees danger scene smoothly, improve escape probability.
This utility model adopts folding flexible material due to head-shield, is convenient for carrying, has seal；Adopt electrical pump and set up smog, toxin inductive transducer at air inlet, thus substituting traditional filtering tank and airway so that fire-fighting guard shield compact of saving oneself, with low cost, it is simple to universal, be conducive to the emergency evacuation under accident.Additionally, this head-shield is close to zero scrappage, it is only necessary to just can reuse for battery charging, use simple, it is not necessary to training can be proper use of.Universal and the use of this fire-fighting protective hood, it is possible to increase personnel escape's efficiency, reduces casualties, improves rescue efficiency.
The above; it it is only preferred embodiment of the present utility model; not this utility model being done any pro forma restriction, those skilled in the art utilize the technology contents of the disclosure above to make a little simple modification, equivalent variations or modification, all fall within protection domain of the present utility model.
