It is composed of a heat radiating source, fixed heat isolator, movable heat isolator, specimen fixing and supporting unit, temp sensors, controller, display, and accessories.
Description
Technical field
The invention belongs to the security against fire technical field, be specifically related to a kind ofly produce far red light simulation scene of a fire thermal environment, be used to test the comprehensive test device of penetrating quality of anti radiant heat for personal guard equipment of firemen based on radiant heat source.
Background technology
In the fire-fighting under battle conditions, flame is one of direct, the most dangerous damage factors of facing of fireman, flame mainly constitutes a threat to fireman's personal safety by conducting heat and radiant heat dual mode, so the penetrating quality of anti radiant heat performance is usually as one of leading indicator of weighing fireman's individual protective equipment performance.In recent years, along with being rooted in the hearts of the people of " people-oriented " idea, fireman's personal protection receives more concerns, and the standard relevant with fireman's individual protective equipment is in recent years in succession by system revision and issuing and implementation.In the GA6-2004 of new revision " fireman put out a fire Protective Boots " standard, GA88 " fireman's protective clothing for proximity fire fighting " standard and new " fireman's rescue protective clothes " industry standard of formulating, the penetrating quality of anti radiant heat performance indications of all clear and definite equipment, and its method of testing made detailed regulation, as shown in table 1:
The performance test of table 1 penetrating quality of anti radiant heat requires to gather
At present, China does not still have to satisfy the penetrating quality of anti radiant heat performance testing device of above-mentioned test request, the penetrating quality of anti radiant heat performance that existing similar testing arrangement is mainly used to test textile fabric, the radiant heat source of such experimental rig is generally the infrared ray halogen tungsten lamp, the about 1KW/m of radiation heat flux that can produce
2, can't satisfy the testing requirement of above-mentioned penetrating quality of anti radiant heat for personal guard equipment of firemen.Along with carrying out and implementing of standard, Bi Yao research technique and the test that can't be accurate and effective and the problem of checking equipment penetrating quality of anti radiant heat performance become increasingly conspicuous for want of, it is very necessary therefore to develop a kind of penetrating quality of anti radiant heat performance synthesis testing arrangement that satisfies above-mentioned requirements.
Summary of the invention
Close testing arrangement, to solve the problem that current shortage experimental rig is used to test penetrating quality of anti radiant heat for personal guard equipment of firemen.
Integration device for testing penetrating quality of anti radiant heat for personal guard equipment of firemen provided by the invention, its operation principle is to produce far red light simulation scene of a fire thermal environment by radiant heat source, sample is placed in this environment, specimen temperature will raise gradually under photothermal effect, estimate the penetrating quality of anti radiant heat performance of this equipment then by the rising value of temperature sensor measurement sample back temperature.
The integration device for testing penetrating quality of anti radiant heat for personal guard equipment of firemen that the present invention proposes is divided into support platform, test macro and control system three parts from structure.Wherein support platform is made by metal material, form by rectangle desktop and dismountable table leg, spoke, the equal fixed placement of the equipment of test macro, control system on support platform, the whole height of support platform with make things convenient for the staff stand the operation be as the criterion.
Among the present invention, test macro by radiant heat source and support thereof, fixedly heat-proof device, mobile heat-proof device, sample is fixing and support system, temperature sensing device and bolograph are formed.Wherein:
Radiant heat source and support thereof are arranged on an end (as left end) of support platform.For satisfying testing requirement better, the radiant heat source of this device can be selected the hot device of the directed intense radiation of high temperature far infrared for use, and its greatest irradiation heat flux is greater than 40KW/m
2Radiant heat source is arranged on the support, and support is fixed on by screw on the desktop of support platform, and the effect of support is to make between the desktop of radiant heat source and support platform to keep a determining deviation, avoids the radiant heat direct irradiation and causes the support platform damage.
Fixedly heat-proof device is positioned at the right side of radiant heat source, and by fixing heat screen, fixedly heat screen support, circulation are formed, fixedly the heat screen size is slightly larger than the hot device of the directed intense radiation of high temperature far infrared, is used for block radiation heat and rearward shines; In the fixing center of heat screen a through hole is set, the size of through hole is by the decision of tested sample size, and radiant heat through hole thus passes to be radiated at and is used for test on the sample.
Mobile heat-proof device is made up of mobile heat screen, roller, motor, gear, mobile heat screen carriage, mobile heat screen support, and mobile heat screen size is slightly larger than the fixedly clear size of opening at heat screen center; Mobile heat screen is fixed in the mobile heat screen carriage, mobile heat screen carriage links to each other with mobile heat screen support by roller, can in the scope of setting, move at mobile heat screen under the effect of motor, thereby whether control is shone on the sample by the radiant heat that fixing heat screen central through hole sees through.Fixedly the surface treatment of heat screen, mobile heat screen becomes black, is convenient to absorb to greatest extent radiant heat, reduces reflection, reduces the heat affecting to surrounding environment.Fixedly heat screen, mobile heat screen are hollow structure, and two ends are provided with delivery port, water inlet up and down, can link to each other the water flowing cooling with water pipe.
Sample is fixed and is reached the right side that support system is positioned at removable heat-proof device, comprise specimen holder, specimen holder support, roller and guide rail, specimen holder is made up of two identical square frames and wing nut, and sample is placed in two frameworks, fix by wing nut, simple and convenient; The specimen holder support is placed on the guide rail, can slide arbitrarily on guide rail by roller, can change the distance between sample and the radiant heat source thus, thereby reaches the purpose of regulating radiant heat density that sample bears.
Specimen holder places on the specimen holder support.Fixedly the support of heat screen, mobile heat screen, specimen holder and infrared source (high temperature far infrared directed intense radiation hot device) support is similar, bearing height with guarantee the hot device of the directed intense radiation of infrared source high temperature far infrared, fixedly the mid point of heat screen, mobile heat screen, specimen holder is as the criterion on same straight line.
Temperature sensing device mainly is made up of 3 thermocouple probes and 3 supporting transmitters, and thermocouple probe is fixed on three different test points at the sample back side, helps improving precision of test result.
Bolograph is to be used for the equipment of measuring radiation heat flux size, is used for determining the distance between sample and the radiant heat source in this device, and its accuracy relation is one of vitals of this device to precision of test result.
