Public place, such as station, airport, Plaza etc..And with the continuous improvement of economic level, people are more and more closed
Safety this topic is noted, it was recognized that safety has become in people's daily life and its important one
Point.More occasions need to provide higher-quality detector gate, such as high-level meeting, exhibition center, museum and especially big business
Etc..
Nowadays, combustion explosion event repeatedly occurs all over the world, criminal often carries inflammable and explosive air-liquid body and implemented
Crime, and current rays safety detection apparatus is more to detect based on metal, function is excessively single, and more security-check process are excessively numerous
Trivial, labor intensive, measurement is not accurate enough, therefore the detection to inflammable air-liquid body need to be broken through.In the modern times of rapid development,
It is badly in need of a kind of vdiverse in function, accurate detector gate of measurement.
The content of the invention
The present invention provides peace that is a kind of while detecting metal and inflammable gas-liquid for the deficiency of existing rays safety detection apparatus detection
Door and method are examined, structure is novel, and automaticity is high, can realize while alarm is sent to metal and inflammable gas-liquid and is carried
Show, meet the demand of modern safety check.
It is a kind of while detect metal and the detector gate of inflammable air-liquid, including safety check door main body, it is characterised in that：Above-mentioned peace
Inspection door main body lower end is equipped with shockproof rubber base；Safety check door main body includes offside door, offside door, pedal and top plate；Above-mentioned offside door and
The inside of offside door is equipped with metal detector；Inflammable gas detector is provided with inside above-mentioned pedal；Also set inside above-mentioned top plate
Air channel is put, wherein air channel import is arranged in top plate upper side, and air channel entrance is disposed with blower fan or fan, ducting outlet arrangement
In top board undersurface；Above-mentioned top plate is additionally provided with the first alarm lamp being connected with metal detector and inflammable gas detector phase
The second alarm lamp and light-emitting diode display even, while the alarm sounding being connected with metal detector, inflammable gas detector
Device.
Metal and the detector gate and method of inflammable air-liquid are detected while described, it is characterised in that including procedure below：Its
The middle metal detection course of work is：Metal detector produces electromagnetic field after being powered, and when there is metal to pass through magnetic field, phase occurs for magnetic field
It should change, the first alarm lamp and alarm sounder being connected with metal detector send sound and light alarm；Inflammable gas is visited
Surveying the course of work is：Blower fan by air channel to blow air below top plate, when there is personnel to carry inflammable air-liquid, containing easy combustion gas
The air of body is in contact with pedal internal gas detector, and detector is made after corresponding detection by connecting with detector
The green second color alarm lamp and alarm sounder connect makes sound and light alarm, and is shown by light-emitting diode display in air easily
Combustion gas, the density rating of liquid.
It is described a kind of while detect metal and the detector gate of inflammable gas-liquid, it is characterised in that：Pedal and the top plate frame
Between offside door and offside door, adopt and be bolted connection.
Described detector gate that is a kind of while detecting metal and inflammable air-liquid body, it is characterised in that：The air inlet in the air channel
Mouth is circular, induction air flow ratio 0.6m/s-2m/s.
The beneficial effects of the present invention are：The present invention relates to a kind of while detect metal and the detector gate of inflammable gas-liquid, tie
Structure is novel, operates steadily.Within the of short duration time that personnel's walking passes through safety check door main body, air velocity will not cause not to personnel
Comfortable to feel, the escaping gas entrained by personnel is blasted into bottom and detector phase with top-down air stream
Contact, the air stream after detection are discharged to detector gate body exterior, will not hinder next detection immediately.Whole detection circulation time pole
End, process are smooth, will not cause personnel's congestion, can comprehensive no dead angle alarm is sent to metal and inflammable air-liquid body simultaneously
And prompting, safety check efficiency is improved while meeting modern safety check demand, saves manpower.
