Technical field
The utility model relates to the colliery operation and uses appliances for labor protection, is specifically related to a kind of methane warning miner's lamp.
Background technology
Mine lamp and methane alarm are requisite safe aids in the operation of colliery.The staff carries for ease, mine lamp and methane alarm is integrated into an instrument at present, and namely for methane warning miner's lamp, this device have the difunctional of illumination and methane warning.Combination is unreasonable to cause the shortcoming that the mine lamp volume and weight is excessive, service life is short but existing methane alarm ubiquity has between parts.
Summary of the invention
To the defective or the deficiency of prior art, the purpose of the utility model is to provide a kind of methane warning miner's lamp.
For realizing above-mentioned technical assignment, the utility model is taked following technical solution:
A kind of methane warning miner's lamp comprises the battery case and the lamp holder that are connected through cable, it is characterized in that, battery pack and short-circuit protector that is connected with battery pack respectively and thermistor are installed in the said battery case; Base plate and reflector are installed in the said lamp holder, single-chip microcomputer, constant-current circuit, a main light source and four secondary light sources are installed on the said base plate, said main light source is connected respectively at constant-current circuit with secondary light source, and said main light source is positioned at the focal position of reflector; Said lamp holder outer setting has air chamber and switch, and the warning circuit and the carrier catalyst element that are connected are installed in the said air chamber; Said switch, short-circuit protector, constant-current circuit and warning circuit are connected with single-chip microcomputer respectively.
Said single-chip microcomputer adopts the PN826 single-chip microcomputer.
The methane warning miner's lamp of the utility model adopts the ultra-high brightness LED light illumination, and photoelectric transformation efficiency is high, than incandescent lamp power saving 70%.Battery adopts the LiMn2O4 ion battery that the novel warning miner's lamp of a kind of environmental protection of power supply is provided.Warning miner's lamp adopts two groups of led light sources respectively as main and auxiliary light source, and main light source adopts constant-current discharge, makes the initial stage of lighting a lamp almost constant with the latter stage illuminance of lighting a lamp.There is Single-chip Controlling to accomplish a series of functions such as the switch transition of intelligent recharge and discharge, major-minor lamp, the warning of methane light in the lamp holder.The characteristics that have that volume is little, in light weight, the life-span are long, non-maintaining, pollution-free, safe and power saving.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Below in conjunction with embodiment and accompanying drawing the utility model is done further explain.
The specific embodiment
Embodiment:
As shown in Figure 1, the methane warning miner's lamp of this embodiment comprises battery case and the lamp holder that is connected through cable, the short-circuit protector 2 and thermistor 4 that battery pack 3 are installed in the said battery case and are connected with battery pack 3 respectively; Base plate and reflector are installed in the said lamp holder; PN826 single-chip microcomputer 1, constant-current circuit 5, main light source 6 and four secondary light sources 7 are installed on the said base plate; Said main light source 6 is connected respectively at constant-current circuit 5 with secondary light source 7, and said main light source 6 is positioned at the focal position of reflector; Said lamp holder outer setting has air chamber and switch 10, and the warning circuit 8 and carrier catalyst element 9 that are connected are installed in the said air chamber; Said switch 10, short-circuit protector 2, constant-current circuit 5 are connected with single-chip microcomputer 1 respectively with warning circuit 8.Functional circuits such as constant-current circuit, short-circuit protector and warning circuit used in the mine lamp all are circuit well known by persons skilled in the art.Those skilled in the art can realize that according to the technique effect of the utility model the circuit in the mine lamp connects.
When warning miner's lamp is placed in the environment of methane gas; Methane gas is surveyed aperture through lamp shell and is got into air chamber; Carrier catalyst element surface in the air chamber produces flameless combustion, and its resistance increases, and the Wheatstone bridge disequilibrium that carrier catalyst element and resistance are formed is the output voltage signal; Handle through single-chip data, by main light source or secondary light source indication.Exceed the alarm point of setting in advance when concentration of methane gas after, continuous three flickers at interval of main light source or secondary light source are carried out optical flare and are reported to the police.
When concrete the use, can waistband be penetrated warning miner's lamp cell jar belt loop, tighten the belt, lamp holder is stuck on the safety cap, make cable in order, open the lamp holder switch on the cap lamp; This warning mine lamp is the two light illuminations of LED, and the switch of pressing as required on the lamp holder can be changed main and auxiliary light source arbitrarily and turn off the light, and wherein: electronic switch conversion logic relation is: closed condition-main light source-secondary light source-close; Turn on king light or auxilliary lamp,, the warning miner's lamp calibration of not reporting to the police is described if during continuous flicker at interval six times.If at interval continuously flicker is three times, explain that warning miner's lamp detects and methane gas arranged, the indication of reporting to the police in the surrounding environment.During use, should be earlier warning miner's lamp be ventilated after the calibration, can normally use.
The methane warning miner's lamp of the utility model discharges and recharges and adopts full-automatic management circuit, and constant voltage after the first constant current is adopted in charging, and by Single-chip Controlling, during the warning miner's lamp charging, when cell voltage >=4.2V ± 0.05V, charging current is broken off in the additives for overcharge protection action.Surpass 12 hours and additives for overcharge protection when not moving yet when the charging interval, charging current is broken off in the overtime protection action of charging.When cell voltage≤2.9V, to cross and put the protection action, warning miner's lamp extinguishes automatically, needs again the charging back to use.When the warning miner's lamp failed because, the short-circuit protector of holding circuit is at 15ms internal cutting off power supply, and pending fault is opened switch after removing again, can recover illumination.Above kinds of protect function has guaranteed that warning miner's lamp can use safely in inflammable, explosive environments.King light LED constant-current driving: can guarantee that the key lights flux can be because of the variation decay rapidly of cell voltage in the design work time.
