Description

Mine lamp with gas alarming function
Technical field
This practicality relates to a kind of mine lamp, relates in particular to a kind of mine lamp with gas alarming function.
Background technology
As everyone knows, the Device in Gas under the coal mine is accumulated to certain concentration just can produce blast, and the Main Ingredients and Appearance of gas is a methane, and its molecular formula is CH 4, CH 4The lower limit of aerial blast percent concentration is 5%, and the upper limit is 15%.So people have adopted gas to detect and the early warning equipment for avoiding owing to gas explosion causes the mass casualties.According to pertinent regulations: on certain working face, when fire damp gas concentration reached 1%, early warning system should be sent alarm signal, so that have time enough to evacuate to safety place the miners of underground work.Should admit, if this gas early warning system is able to normally and effectively bring into play its function, just the accident that constantly causes the coal miner injures and deaths because of gas explosion can not be arranged, and especially big gas explosion accident has taken place in the recent period again and again, because the gas early warning system is not brought into play its due effect, a large amount of personnel's injures and deaths have been caused.Here it is the at present defective or the imperfect place of coal mine gas alert device that is to say that present employed gas early warning system also has further perfect necessity.
Existing gas detecting alarm is in the deficiency of structure and serviceability aspects such as (effects), and the miners that make in underground work are not easy to everybody and have an alarm, and can not obtain the caution signal that gas density exceeds standard in the very first time.Therefore miners' life does not ensure, more ability does not exercise mastery over one's own fortune.
Summary of the invention
The purpose of this utility model is: overcome prior art, provide a kind of and integrate mine lamp, security alarm, and compact conformation, layout are ingenious, low cost of manufacture, safe and reliable, the effective mine lamp with gas alarming function.
The technical solution of the utility model is: comprise bulb, lamp socket, safety cap and battery, dispose the combustible gas alarm, the combustible gas alarm is made of combustible gas sensor and control circuit, and the combustible gas alarm is by storage battery power supply.
Combustible gas sensor described in the utility model is a firedamp sensor.The combustible gas sensor is installed in mine lamp reflection shield rear portion.
Control circuit described in the utility model is made up of triode, relay, integrated package of pressure-stabilizing, buzzer, adjustable potentiometer, electric capacity, resistance, relay indicating light, warning light indicator lamp.Wherein triode, relay, integrated package of pressure-stabilizing, buzzer, adjustable potentiometer, electric capacity, resistance are integrated on the main control board, and buzzer is arranged on the inside top of safety cap.Described relay indicating light and warning light are installed in the shade dead ahead, and it is the dead ahead of eyes that its luminous component then is emerging in the shade below.Main control board is arranged at mine lamp inside.
The utlity model has following characteristics: 1, compact conformation, layout is ingenious, integrates mine lamp and gas alarming function, and is easy to carry, has practicality, can accomplish one of staff; 2, simple in structure, the working time is long: the warning circuit power supply directly adopts the mine lamp mains lighting supply, need not add power source special in addition,, especially because of mine lamp power is a battery, its capacitance is big, and stream time can reach 8-10 hour; 3, safe and reliable sensitivity is adjustable: suppose that the warning methane concentration that sets is 1% (by pertinent regulations), the utility model is in the environment of methane concentration 〉=1%, then start alarm buzzer and warning light at once, just can remove until methane concentration<1% an o'clock warning.4, cheap for manufacturing cost, be about below 50% of similar portable gas explosion detection alarm instrument, it has the good popularization and the market competitiveness, is widely used in the explosive places of various imflammable gas such as gas.
