Description
Technical field
The utility model belongs to telltale, is a kind of carry-on wearing type gas in mine alarm.
Background technology
At present, Gas Explosion Accidents in Coal Mines happens occasionally, and directly threatens miner's personal safety, in case gas explosion accident takes place, entail dangers to miner's life brings tremendous loss for miner's family, enterprise and country.It is to adopt large-scale methane Concentration Measurement device by the professional that existing coal mine gas concentration detects, and timing under mine, location are detected, and it is narrow, untimely that it exists the detection involvement aspect; Detector volume is big, weight is big, be not easy to carry and the high deficiency of cost.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of simple in structure, and volume is little, and is in light weight, wears conveniently, and the accuracy of detection height is reported to the police accurately, and safe and reliable, cost is low, widely applicable carry-on wearing type gas in mine alarm.
The technical scheme that solves its technical matters employing is: a kind of carry-on wearing type gas in mine alarm, be characterized in: it comprises box body 16, box body 16 is provided with net window 2, be built-in with gas alarm circuit at box body 16, this circuit is electrically connected with the current amplifier 17 with gas concentration sensor 3 by the input end of single-chip microprocessor 4, the output terminal of single-chip microprocessor 4 is electrically connected with midget relay 9, and midget relay 9 is electrically connected with mine lamp 12, mineral light 11.Current amplifier 17 with gas concentration sensor 3 is electrically connected and is formed by integrated circuit die I C1, potentiometer RW, resistance R 1-R7, capacitor C 1, C2, gas concentration sensor 3.
Carry-on wearing type gas in mine alarm of the present utility model utilizes mineral light as power supply, need not independent power supply, and power consumption is little, saves electric energy; Complete machine structure is simple, and volume is little, and is in light weight, wears conveniently, and the accuracy of detection height is reported to the police accurately, and safe and reliable, cost is low, and is widely applicable.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is carry-on wearing type gas in mine alarm structure cross-sectional schematic.
Fig. 2 is the schematic side view of Fig. 1.
Fig. 3 is gas alarm circuit figure.
Fig. 4 is carry-on wearing type gas in mine alarm and mine lamp connection diagram.
Embodiment
With reference to Fig. 1-2, wearing type gas in mine alarm has box body 16 with oneself, and box body 16 is connected with box bonnet 8 by box protecgulum 1 and forms.Be provided with net window 2 on box protecgulum 1, the net of net window 2 is a copper mesh, and copper mesh plays the back-fire relief effect.Box bonnet 8 is provided with hook 10, and alarm can be hung on miner's the waistband by the hook on the box bonnet 8 10.On the circuit board 5 of box body 16, be equipped with gas alarm circuit, the gas concentration sensor 3 of gas alarm circuit places on the circuit board 5, over against net window 2 one sides, single-chip microprocessor 4, midget relay 9, connection terminal 6 place the inboard on the circuit board 5, and lead location sealed interface 7 is set on box body 16.
With reference to Fig. 3, gas alarm circuit is electrically connected with the current amplifier 17 with gas concentration sensor 3 by the input end of single-chip microprocessor 4, the output terminal of single-chip microprocessor 4 is electrically connected with midget relay 9, and midget relay 9 is electrically connected with mine lamp 12, mineral light 11.Current amplifier 17 with gas concentration sensor 3 is electrically connected by integrated circuit die I C1, potentiometer RW, resistance R 1-R7, capacitor C 1, C2, gas concentration sensor 3 (both resistance R X) to be formed.Single-chip microprocessor 4, midget relay 9, gas concentration sensor 3, integrated circuit die I C1, potentiometer RW, resistance R 1-R7, capacitor C 1, C2 are the commercially available prod.Gas concentration sensor 3 adopts combustion gas, gas sensor all can.Gas concentration sensor 3 of current amplifier 17 (both resistance R X) and fixed resistance R1-R3 form unbalanced bridge.When gas density under the mine when being no more than the limit of regulation, fixed resistance R1, R2 resistance equate that resistance R 3 equates with gas concentration sensor 3 (resistance R X) resistance, this moment, electric bridge was an equilibrium state, the output of output terminal no current, gas alarm circuit is not worked, and mine lamp 12 is the normal illumination state.When the limit of gas density overshoot under the mine, gas concentration sensor 3 (resistance R X) resistance changes, this moment, electric bridge lost balance, output terminal produces the deviation electric current, this electric current process is by resistance R 4-R7 and capacitor C 1, the filtering circuit that C2 forms carries out filtering, be amplified into the input end of single-chip microprocessor 4 by integrated circuit die I C1, after the plug-in of single-chip microprocessor 4 is for data processing, carry out service intermittent by its output terminal output signal control midget relay 9, the normally closed contact of midget relay 9 is break-make intermittently, make mine lamp 12 intermittently glittering, to reach the purpose of flashing light alarm.Potentiometer RW is a zero potentiometer.
With reference to Fig. 4, with oneself wearing type gas in mine alarm 15 by the sealed connector 13 that is connected respectively with ore deposit cap 14 on mine lamp 12 be connected with mineral light 11.Alarm 15 of the present utility model can be according to operation needs under the mine, and everybody wears, or some of the staff wear.It is also very easy to connect alarm 15 of the present utility model on the circuit of existing mine lamp 12.
