Technical field
The utility model relates to a kind of fire rescue analog training device, and particularly a kind of fire extinguishing effectiveness detecting device of judging based on laser beam shielding can carry out the judgement of science fast and accurately to fire extinguishing effectiveness.
Background technology
At present, various fire rescue analog training devices are widely used in fire drill and the manoeuvre, are to measure the temperature of fire combustion zone flame such as propane flame, collect the volume of effective fire water or fully with people's micro-judgment for the existing method of the detection of fire extinguishing effectiveness.Said method adapts to the single only applicable fire water of fire extinguishing agent, exist and measure the deficiencies such as inaccurate, that the response time is long, device volume is large, and for fire disaster simulation trainer such as aircraft, the chemical plant etc. of complex structure, finite volume the measuring equipment of collecting effective fire water often can't be installed.Because the limitation of existing fire extinguishing effectiveness detection method makes it be difficult to satisfy the demand of fire disaster simulation trainer.
Summary of the invention
In order to address the above problem, the utility model provides a kind of fire extinguishing effectiveness detecting device of judging based on laser beam shielding, can carry out fast and accurately the judgement of science to fire extinguishing effectiveness.
The technical solution adopted in the utility model is: a kind of fire extinguishing effectiveness detecting device of judging based on laser beam shielding, it is characterized in that the both sides in the flame combustion district arrange respectively transmitting terminal and the receiving end of laser-correlation sensor, transmitting terminal and receiving end are connected with controller by cable, transmitting terminal and receiving end are separately positioned in the air shield protection pipeline, and the air shield protection pipeline outside is connected with positive pressure ventilation pipe.
Described air shield protection pipeline is connected with just pressure ventilation pipe is airtight, and the cable that transmitting terminal is connected with receiving end is passed by air shield protection pipeline or positive pressure ventilation pipe.
Described air shield protection pipeline peripheral hardware has the insulating refractory layer.
Described positive pressure ventilation pipe peripheral hardware has the insulating refractory layer.
Described positive pressure ventilation pipe is connected with blower fan, and blower fan is provided with air inlet, and the air inlet place is provided with air filter.
Described blower fan from the flame combustion district greater than 50 meters.
Described positive pressure ventilation pipe to air shield protection duct section is arranged on underground.
The utility model is by arranging the laser-correlation sensor that can penetrate flame, the laser-correlation sensor setting is in air shield protection pipeline, air shield protection pipeline is connected with the clean wind regime of malleation, can blow down pollutant and can dispel the heat again, make the laser-correlation sensor avoid on-the-spot complex environment and make it can not normal year work such as the impact of the fire extinguishing agent that sprays and high temperature; Laser-correlation sensor laser signal can be had efficient fire-extinguishing chemical to block partition by fire water, foam, dry powder etc., make the judgement of fire extinguishing effectiveness according to the time of blocking partition, judged result is scientific and reasonable, this fire extinguishing effectiveness detecting device of judging based on laser beam shielding has strong adaptability applicable to fire extinguishing agents such as fire water, foam, dry powder, response time is short, highly sensitive, antijamming capability is strong, installs the advantages such as easy for installation.
