(SF6) occur generally cannot detect during leakage, so easily patrol officer is damaged, when running into poisonous gas leakage,
For preventing from sucking pernicious gas, it is ensured that the personal safety of patrol officer, need to withdraw in time and oxygen is provided in time for patrol officer
Gas or clean air.Therefore need one badly to carry out to poisonous gas leakage reporting to the police and provide clean tidal air for patrol officer
Body thus reduce SF6The safety cap of gas soakage.
Content of the invention
The purpose of this utility model is, overcomes the deficiencies in the prior art, provides a kind of electric inspection process safety cap, passes through
SF is set6Detection device and oxygen air bag, when detecting SF6After gas, sending alarm, inspector can utilize safety cap
Interior oxygen air bag provides oxygen, minimizing SF by cover of exhaling6Gas soakage, at utmost ensure that the person of patrol officer
Safety.
For solving above-mentioned technical problem, the technical solution of the utility model is: electric inspection process safety cap, including protecting helmet shell
Body, helmet shell front is provided with illuminating lamp, described helmet shell fixes SF6Gas detection apparatus, helmet shell
Inside is provided with interlayer, is covered with the oxygen air bag matching with spacer shape in interlayer, and described oxygen air bag is by through protecting helmet shell
The appendix of body connects cover of exhaling, and described appendix is provided with air valve.
SF6Gas detection apparatus can detect SF6Gas simultaneously sends alarm signal, in inspector can utilize safety cap
Oxygen air bag, opening air valve provides oxygen by cover of exhaling, and reduces SF6Gas soakage, at utmost ensure that patrol officer
Personal safety.
Further, described SF6Gas detection apparatus includes power module, SF6Sensor and temperature sensor；Described
SF6Sensor and temperature sensor electrically connect with analog to digital conversion circuit respectively, and analog to digital conversion circuit electrically connects with single-chip microcomputer, monolithic
Machine electrically connects with nixie display and buzzer siren.
Hardware circuit mainly includes SF6Sensor circuit, temperature sensor, A/D analog-digital converter, power module, monolithic
Machine, buzzer alarm circuit, digital-scroll technique circuit.Safety cap is become one with warning circuit unit, it is achieved down-hole SF6With
The functions such as real-time monitoring, alarming value setting, the buzzing warning of temperature.Sensor assembly gathers SF respectively6And temperature signal, signal
Become data signal after sending ADC change-over circuit；The signal of all collections processes and shows existing concentration, temperature value through single-chip microcomputer,
Compare measurement concentration with the alarm threshold value data being previously set, if beyond the limit value of regulation, then warning system produces honeybee
Ring is reported to the police, and prompting miner takes care, and withdraws in time.
Preferably, described helmet shell is fixed with the alarming in short range of electric power device from charged pool.
Arranging alarming in short range of electric power device can be at worker exposure's high-tension apparatus, after losing effective and safe distance, and alarm meeting
Send ear-piercing sound, remind staff away from, when staff keeps safe distance again, alarm stop alarm.
The beneficial effects of the utility model are: electric inspection process safety cap, including helmet shell, helmet shell front sets
There is illuminating lamp, described helmet shell fixes SF6Gas detection apparatus, is provided with interlayer, in interlayer inside helmet shell
Being covered with the oxygen air bag matching with spacer shape, described oxygen air bag is exhaled by connecting through the appendix of helmet shell
Cover, described appendix is provided with air valve.By arranging SF6Detection device and oxygen air bag, when detecting SF6After gas, send
Alarm, the oxygen air bag in inspector can utilize safety cap provides oxygen by cover of exhaling, reduces SF6Gas sucks
Amount, at utmost ensure that the personal safety of patrol officer.
