Abstract
The utility model relates to a miner's light helmet with a gas alarming device. Electronic circuit boards of a gas density detecting instrument and a sound-light alarming instrument are arranged in an electronic element barn in front of the helmet, and the front face of a helmet brim is provided with a work indicating light of a gas density detecting alarm and a gas density grading indicating luminous tube. All underground workers are provided with lighting and gas alarming safety protecting devices so that gas detecting points are spread over all work faces. The utility model has the advantages of direct viewing performance and convenient operation. In addition, the utility model is provided with a purpose-made miniature anti-explosion switch which has the advantages of small size, light weight and tight seal.
Description
Technical field
The utility model relates to miner light cap and the methane Concentration Measurement warning instrument that uses in a kind of mine.Especially a kind of gas warning head lamp cap.
Background technology
At present, the miner light cap that uses in mine is two different equipments with methane Concentration Measurement warning instrument, and miner light cap is illumination and cephalic protection just, does not possess other functions.
Summary of the invention
The utility model provides a kind of miner light cap with gas alarm, and mine lamp, ore deposit cap and gas detection equipment are arranged, and it is characterized in that being provided with the electronic component storehouse in the miner light cap front portion, and methane Concentration Measurement and sound and light alarm instrument are housed in the element storehouse.The relay indicating light of methane Concentration Measurement alarm and gas density classification indication luminous tube are located at the front end of the brim of a hat.
Next door at mine lamp, a miniature anti-riot switch is arranged, it is the power switch of mine lamp and alarm, the structure of this miniature anti-riot switch is: the center of switch is the magnetic switch pipe, the input of switch, output the two poles of the earth are electrically connected with the two poles of the earth of a magnetic switch pipe respectively, a permanent magnet is housed on the next door of magnetic switch pipe, and the N of permanent magnet, S utmost point line are perpendicular to the magnetic switch pipe.Permanent magnet is advanced the magnetic switch pipe, and switch is just connected, otherwise switch just disconnects.
The beneficial effects of the utility model are to make all staff on board of down-hole all be equipped with the safety device of illumination and gas alarming, make the gas test point spread all over all working face, and, directly perceived, be convenient to operate.
Description of drawings
Below in conjunction with Figure of description the utility model is further specified.
Figure of description 1 is the structure chart of an embodiment of the present utility model.
Figure of description 2 is structure charts of miniature anti-riot switch.
1. miner light caps among the figure; 2. mine lamp; 3. miniature anti-riot switch; 4. electronic component storehouse; 5. the brim of a hat; 6. the relay indicating light of methane Concentration Measurement alarm; 7. luminous tube is indicated in the gas density classification; 8. storage battery.
The specific embodiment
In the front of miner light cap 1 mine lamp 2 is housed, below mine lamp 2, be provided with electronic component storehouse 4, the electronic circuit board of methane Concentration Measurement and sound and light alarm instrument is housed in the element storehouse, the relay indicating light 6 that the methane Concentration Measurement alarm is arranged in the front of the brim of a hat 5, also has gas density classification indication luminous tube 7 in the front of the brim of a hat 5, storage battery 8 is contained in the right and left of miner light cap 1, a miniature anti-riot switch 3 is arranged on the next door of mine lamp 2, the structure of this miniature anti-riot switch is: the center of switch is a magnetic switch pipe 11, the two poles of the earth 9 and 10 of switch, the two poles of the earth with a magnetic switch pipe 11 are electrically connected respectively, a permanent magnet 12, the N of permanent magnet 12 are housed on the next door of magnetic switch pipe 11, S utmost point line is perpendicular to magnetic switch pipe 11.Permanent magnet 12 is advanced magnetic switch pipe 11, and switch is just connected, otherwise switch just disconnects.The advantage of this miniature anti-riot switch is that volume is little, in light weight, sealing is tight.
