Detailed description of the invention
Below the utility model is described further:
As shown in Figure 1, the mine lamp of a kind of gas management and early warning, comprise lamp body 12, lamp body 12 rear end connects wire 9 by connector 13 and is connected with power supply 10, lamp body 12 upper end is provided with acousto-optic prior-warning device and gas detecting device, and acousto-optic prior-warning device is connected wire 9 with gas detecting device by connector 13 and is connected with power supply 10.
Further, also comprise explosion-resistant enclosure 5, acousto-optic prior-warning device and gas detecting device are installed in explosion-resistant enclosure 5.
Preferably, also comprise fixture 8, explosion-resistant enclosure 5 is connected with connector 13 by fixture 8.
Further, acousto-optic prior-warning device comprises signal processor 4, sound-producing device 6 and circuit board 7, and signal processor 4 and sound-producing device 6 are arranged on circuit board 7.
Further, gas detecting device comprises screen pack 2 and gas sensor 3, and screen pack 2 is arranged at lamp body 12 front end, and gas sensor 3 is connected with acousto-optic prior-warning device.
Preferably, lamp body 12 front end is provided with cloche 1, well plays the effect of protection lamp body.
Preferably, lamp body 12 lower end is provided with switch 11, is convenient to free switch mine lamp 12.
Preferably, connector 13 lower end is provided with right angle frame 14, serves support fixing effect to lamp body 12.
Composition graphs 2: operation principle of the present utility model: mine lamp entirety is fixed on safety cap by right angle frame, gas detecting device is connected with mine lamp by connector, play fixation, the gas of down-hole is through gas detecting device, first by screen pack by coal dust larger in gas, dust etc. filter out, gas passes through gas sensor subsequently, there is corresponding linear change in the resistance value of the different gas sensor of the concentration because of methane gas, produce the different signals of telecommunication, when the signal of telecommunication is by signal processor, the signal of telecommunication amplifies by signal processor, be converted into data signal by single-chip microcomputer process simultaneously, when gas density reaches 1%, data signal is sent to sound-producing device and mine lamp by signal processor, make mine lamp periodic flicker, mine lamp can recover normal illumination after again pressing on & off switch, sound-producing device will send chimes of doom and remind miner to withdraw in time.
This experiment with novel by gas detecting device, acousto-optic prior-warning device combines with mine lamp, main composition due to gas is methane, its relative mass is lighter than air, easily accumulate in top, goaf, in enclosed area, getting working face top, blind lane and zone of silence, therefore designed and installed top at mine lamp.Methane gas is by gas sensor, and when gas density is different, sensor has different resistance, resistance and along with the change in concentration of gas be that line changes.By sensor, this physical signalling of concentration is converted into the signal of telecommunication.By signal processor, the signal of telecommunication is being amplified, be converted into data signal by single-chip microcomputer process simultaneously, single-chip microcomputer more just signal transmission send early warning sound to sound-producing device, simultaneously by signal transmission to mine lamp, make its periodic flicker, mine lamp can recover normal illumination after again pressing on & off switch.Because subsurface environment is complicated, adopt sound-light double alarm mode, mine lamp power supplies mine lamp and gas management and prior-warning device simultaneously.
