Description
Technical field
The invention belongs to thermal safety engineering technical field of measurement and test, be specifically related to a kind of telescopic flammable liquid igniter.
Background technology
When confined space does liquid fire combustion experiment, fixing point firearm is usually used to light liquid.Igniter end is placed on flammable liquid surface, and after some burning liquid, flame directly acts on igniter.Therefore, after experiment terminates, igniter scaling loss is serious.Meanwhile, igniter, just to flame, can affect experiment flame forms, impact experimental result.Require strict experiment for air-tightness, as altitude chamber test, the circuit of igniter is difficult to arrange, needs to pass from wall punching, and carries out encapsulation process to hole.When converting ignition location, need to rethink wiring when fixing igniter moves.
Summary of the invention
The object of this invention is to provide a kind of telescopic flammable liquid igniter, can be used for the flammable liquid lighting confined space, solving circuit in confined space should not arrange, lighting rear igniter can not remove, resistance wire scaling loss is serious, and affects the technical problem of results of combustion tests.
To achieve the above object, the technical scheme that the present invention takes is: a kind of telescopic flammable liquid igniter, comprise igniter, expansion link, remote controller, bracing frame, it is characterized in that: described igniter is made up of resistance wire, remote control switch, power sources in series, resistance wire is fixed on the front end of expansion link, remote control switch is arranged between resistance wire and power supply, remote control switch is arranged on the front end of expansion link, and expansion link rear end is provided with remote control induction installation, bracing frame is connected with expansion link rear end, plays fixed support effect to it; Remote controller is provided with ignition switch key, stretching key, shrinks key and LED light, remote controller for control igniting and start and closedown, the stretching of expansion link, contraction; Remote control induction installation and remote control switch and remote controller wireless connections, the stretching of remote control induction installation expansion link, contraction.
Advantage of the present invention and good effect are:
(1), the present invention after lighting flammable liquid, igniter can be controlled and leave, eliminate the infringement of burning to resistance wire, eliminate resistance wire to the impact of combustion flame, make experimental result more accurate.
(2), structure of the present invention is simple, do not need to arrange circuit, the open and close of remote pilot igniter, the flexible, easy to use of expansion link during use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Wherein: 1 is igniter, 2 is expansion link, and 3 is remote controller, and 4 is bracing frame, and 5 is resistance wire, and 6 is remote control switch, and 7 is power supply, and 8 is remote control induction installation, and 9 is ignition switch key, and 10 is stretching key, and 11 for shrinking key, and 12 is LED light.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
Embodiment 1:
A kind of telescopic flammable liquid igniter, comprise igniter 1, expansion link 2, remote controller 3, bracing frame 4, described igniter is composed in series by resistance wire 5, remote control switch 6, power supply 7, resistance wire 5 is fixed on the front end of expansion link 2, and remote control switch 6 is arranged between resistance wire 5 and power supply 7, and resistance wire 5 is connected with remote control switch 6, remote control switch 6 is connected with power supply 7, and expansion link 2 rear end is provided with remote control induction installation 8, bracing frame 4 is connected with expansion link 2 rear end, plays fixed support effect to it; Remote controller is provided with ignition switch key 9, stretching key 10, shrinks key 11 and LED light 12, for control igniting start and closedown, the stretching of expansion link 2, contraction.Remote control induction installation 8, remote control switch 6 and remote controller 3 wireless connections.Remote control induction installation 8 controls stretching, the contraction of expansion link 2.
When carrying out the experiment of confined space flammable liquid, igniter 1 is put into confined space, resistance wire 5 is placed on flammable liquid surface (distance flammable liquid surface 0 ~ 2cm), switches on power 7.When needing igniting, once, LED light 12 lights to press ignition switch key 9 on remote controller 3, represents that igniter 1 starts the work of being energized.Wait for some seconds, flammable liquid cognition is lighted.After lighting, more once, LED light 12 is extinguished to press ignition switch key 9 on remote controller 3, and igniter 1 quits work.Press and shrink key 11, expansion link 2 shrinks, and heating wire 5 is removed burning things which may cause a fire disaster place.At the end of experiment, press stretching key 10, original ignition location got back to by expansion link 2, and convenient experiment next time uses.
Embodiment 2:
Common laboratory flammable liquid used is alcohol, normal heptane, gasoline, kerosene, diesel oil, and its ignition temperature is respectively 363,204,280,220,220 DEG C.Power supply 7 can select 12V dc source, and model C r20Ni80 nickel reeling selected by heating wire 5, and when selecting nickel reeling diameter to be 1mm, resistance value is 1.44 Ω/m, the long 10cm of nickel reeling, and density is 8.4g/cm
3.Heating wire 5 is heated to 400 DEG C from 0 DEG C, needs heat.
Q＝cM(T
2-T
1)
Wherein: c is nickel reeling specific heat capacity, 0.44J/g DEG C;
M is the quality selecting nickel reeling;
T2 for needed for reach temperature;
T1 is initial temperature.
Nickel reeling power
P＝U
2/R
Wherein: U is supply voltage;
R is for selecting nickel reeling resistance.
Heating wire 5 reaches ignition temperature required time
t＝Q/P
In this selection of material, only need 0.1s just can reach temperature required.Flammable liquid is volatilizable goes out fuel gas, by heating wire 5 placed on it 0-2cm, by the liquid that ignites rapidly.Heating wire distance flammable liquid liquid level is too high, may not ignite.
