Description
Technical field
The utility model is related to security against fire field, particularly a kind of scene of a fire flue gas toxity monitoring device.
Background technology
Combustible can produce a large amount of high temperature, poisonous dense smoke in fire.These dense smokes can cause dysopia to personnel escape.
High-temperature flue gas can be to artificial into heat injury.Toxic component in suction flue gas such as hydrogen cyanide, hydrogen chloride, carbon dioxide, an oxidation
It is even dead that carbon etc. can cause human body to lose escape capability.The smog that fire is produced has that smoke density is big, smoke temperature change fast, cigarette
The characteristics of toxic component is complicated in gas.At present for although the development service condition that animal exposes contamination device has many reports.
But for the mixed gas that burning is generated, particularly not exclusively know that the contamination research of the mixed gas of composition is also little, skill
Art is also immature.Because danger is larger during fire test, personnel cannot observe fire hazard environment and animal contaminated in testing ground
State.
For this special environment of fire, Inhalation device requires flexibly to move, data accurately, in toxicant exposure box
Poisonous substance is identical with fire field environment and energy fully, rapidly be broadcast to the animal that is contaminted；The tested environment of animal has lasting stablizing
Property；All animal subjects can be exposed in concentration identical poisonous substance environment.Existing animal exposure contamination device is mainly used in
Toxicity assessment to gas at normal temperature.And substantial amounts of heat radiation can be produced in fire, radiant heat can be produced to the result of toxicity assessment
Affect.Therefore it is considered as excluding interference of the radiant heat to results of animal.Exposure contamination device be also contemplated that can make it is all of
Animal subject is all exposed in the poisonous gas of same concentrations, and same with the gas phase in fire field environment.Existing contamination device
It is mainly used in the constant toxic environment of gas concentration.And flue gas concentration change in the scene of a fire is fast, such as the concentration of HCN can exist from 0ppm
2000ppm is risen in several seconds.It is considered as that flue gas can be made to diffuse to tested moving rapidly, uniformly for scene of fire particular surroundings
At thing mouth and nose, therefore it is considered as making exposure case volume minimization when designing, and designs gas distributor and be passed directly into flue gas and receive
At examination animal mouth and nose.
In addition, the zooperal purpose of fire smoke toxicity be from animal fire smoke exposure in behavior expression and physiology
The change of index derives the behavior expression and pathology of the evacuating personnel when fire occurs, and not only needs the LD50 for testing fire smoke
Value, in addition it is also necessary to monitor behavior and physical signs of the animal in process-exposed, and existing contamination device can be only done animal suction
Enter exposure experiment, be generally used for testing the LD50 values of poisonous substance, therefore, existing animal exposure contamination device cannot be directed to the scene of a fire
Particular/special requirement completes animal exposure exposure experiment.
Utility model content
The purpose of this utility model be to provide it is a kind of can use in scene of fire, for monitoring fire smoke acute toxicity
Non-destructive monitoring system.The system architecture is simple, it is mobile to be easy to, animal used as test can be used to monitor fire smoke under the conditions of lossless
Acute toxicity, it is adaptable to carry out flue gas Monitoring Acute Toxicity in scene of fire.
The technical solution of the utility model is：A kind of scene of a fire flue gas toxity monitoring device, including outer cover and it is worn on experiment
Animal sign monitors with animal；The intake valve for insulating box being provided with the outer cover and being connected with insulating box, the constant temperature

The fire smoke collector of valve connection, is provided with gas outlet and video collector corresponding with insulating box at the top of the outer cover；
The insulating box, thermocouple, animal sign monitors and video collector connect peripheral control unit by sensor wire box.
Animal used as test is positioned in the rotating cage in insulating box, intake valve is opened, fire poison gas will be by fire cigarette
Gas collector continuously enters insulating box；Constant temperature the temperature inside the box is constant, is not affected by flue-gas temperature, and thermocouple can be by storehouse
Interior temperature is sent to controller, when animal used as test is contaminated can the free movement in rotating cage, to observe suction fire poison gas
When animal motion state situation of change so as to evaluator suction fire smoke after escape ability；Animal sign monitors are used
In the physiological characteristic of measurement animal, video collector is used to monitor the motion conditions of animal；Insulating box, thermocouple, animal sign
Monitor and video collector connect peripheral control unit by sensor wire box, to be uniformly controlled.
Preferably, the animal sign monitors include heartbeat sensor, respiration transducer and blood pressure sensor.
The above-mentioned three kinds of sensors that the animal sign monitors are included refers to for topmost three physiology of fast monitored
Mark, i.e. palmic rate, respiratory rate and blood pressure.
Preferably, the homeothermal animal storehouse is two to eight even number, be divided into it is a row or multi-row be placed in parallel, often arrange two
It is individual.
Single insulating box may make monitoring result not accurate enough, but excessive insulating box can increase monitoring complexity again
Degree, can prevent unnecessary cross influence from causing monitoring result inaccurate the arrangement in good order of each homeothermal animal storehouse, and have
Clearly contrast.
Preferably, the bottom of the outer cover is provided with liftable support.
The height of outer cover is adjusted by liftable support, the requirement of different fire scenarios is suitable for.
The beneficial effects of the utility model are：
1st, insulating box can keep animal in constant environment temperature, and thermocouple can in real time be sent to temperature in storehouse
Controller, intake valve can make that flue gas is quick, evenly distribute at the mouth and nose of animal used as test, it is to avoid the difference of exposed environments is to experiment
As a result impact, animal sign monitoring sensor can adhere to animal used as test body surface, and to the physiology sign of animal used as test nothing is carried out
Damage monitoring, the escape performance after the recordable animal acute poisoning of the video collector；
2nd, including heartbeat sensor, respiration transducer and blood pressure sensor animal sign monitors can fast monitored it is most main
Three physical signs wanted, i.e. palmic rate, respiratory rate and blood pressure；
3rd, multiple homeothermal animal storehouses are set, and arrangement in good order, monitor sample can be increased, make monitoring result more accurate
Really；
4th, the height of outer cover is adjusted by liftable support, the requirement of different fire scenarios is suitable for.
