Not only the utility model forms the air curtains on the surfaces of the lenses to prevent an optical device from being contaminated with fine particles of soot, but also the formed air curtains can be kept to be vertical to an optical passage inside a smoke chamber, with stable and uniform pressure and accurate measurement. Since the detection platform is connected into an integral body, the utility model is convenient for installation and debugging.
Description
Technical field
The utility model relates to a kind of light obscuration meter, belongs to a kind of detection platform for smokemeter.
Background technology
For visible detection of polluting in compression-ignited (diesel oil) engine exhaust (smoke evacuation) filter type smokemeter and two kinds of instruments of light obscuration meter are arranged.The light obscuration meter is a kind of novel Artificial Intelligence Instrument.It can carry out real-time and free accelerated test, and it is accurately convenient to measure, and can judge automatically that each time test is meet national standard relevant fixed.Vitals detection platform for smokemeter in the light obscuration meter produces wind and enters smoke-box because most of detection platform are blower fans, makes the pressure transient, inhomogeneous of air curtain to cause air curtain and optical channel out of plumb, influences measurement result.This general detection platform is the branch body structure, the Installation and Debugging inconvenience.
Summary of the invention
The purpose of this utility model provide a kind of can make form air curtain pressure stability evenly, Installation and Debugging detection platform for smokemeter easily.
The purpose of this utility model is to realize like this, it comprises radiating circuit, left lens mount assembly, left and right sides lens, left and right sides adapter sleeve, left and right sides air curtain blast pipe, T type smoke-box assembly, heating and thermostatically-controlled equipment, exhaust gas temperature sensor module, right lens mount assembly and receiving circuit, left and right sides air curtain blast pipe entrance point is connected with two typhoon machines respectively, left and right sides air curtain blast pipe endpiece is adorned left and right sides adapter sleeve respectively, and left and right sides adapter sleeve is installed on respectively between the smoke-box outlet and left and right sides lens mount assembly of T type smoke-box assembly; Left side lens mount assembly, right lens mount assembly and T type smoke-box assembly connect as one by being connected supporting.
The utility model is owing to adopt two air curtain resist technologies, air curtain blast pipe entrance point connects two blower fans respectively in the left and right sides, two independently blower fan produce perpendicular to the air curtain of smoke-box respectively the air curtain blast pipe by both sides the clean air in the external world is blown into the passage of left and right sides lens between exporting with smoke-box, not only make lens surface form " air curtain ", avoid optical device to stain and go up the soot particulate, can also make the pressure stability that forms air curtain even; Connect supporting owing to be provided with, it is as a whole to make that whole detection platform connects, and makes things convenient for Installation and Debugging.

Embodiment
With reference to Fig. 1, present embodiment is by radiating circuit 1, left lens mount assembly 2, left and right sides lens 3,3
1, left and right sides adapter sleeve 4,4
1, left and right sides air curtain blast pipe 5,5
1, T type smoke-box assembly 6, exhaust gas temperature sensor module 7, connect supporting 9, right lens mount assembly 10 and receiving circuit 11 and form.Present embodiment detection platform 13 is installed in the detection case 12 as shown in Figure 2.Remove T type smoke-box assembly 6 and be flexible connection with left lens mount assembly 2 and right lens mount assembly 10 each end, remaining part is fixedly connected.Left and right sides lens 3,3
1Symmetry is installed in the microscope base of left lens mount assembly 2 and right lens mount assembly 10, left and right sides lens 3,3
1Be convex lens.Left side air curtain blast pipe 5 entrance points and a typhoon machine by pipe be connected, right air curtain blast pipe 5
1Entrance point is connected by pipe with another typhoon machine.Left and right sides air curtain blast pipe 5,5
1Endpiece is equipped with left and right sides adapter sleeve 4,4 respectively
1Left and right sides adapter sleeve 4,4
1Be installed on respectively between the smoke-box outlet and left and right sides lens mount assembly 2,10 of T type smoke-box assembly 6.By two independently blower fan produce perpendicular to the air curtain of smoke-box respectively by about the air curtain blast pipe clean air in the external world is blown into the passage of left and right sides lens between exporting with smoke-box.Be provided with into mouth place installation exhaust gas temperature sensor module 7 in the middle of the T type smoke-box assembly 6.Left side lens mount assembly 2, right lens mount assembly 10 and T type smoke-box assembly 6 connect by being connected supporting 9, and with reference to Fig. 3, what connect supporting 9 is profile structure, fixedly connected with left and right sides lens mount assembly 2,10 respectively in its two ends.Radiating circuit 1 is contained in left lens mount assembly 2 other ends, and receiving circuit 11 is contained in right lens mount assembly 10 other ends.Because exhaust gas temperature is higher, entering behind the smoke-box water vapour in the smoke evacuation can the condensation mist formation, influences measurement result.In order to prevent the influence of condensation, heating and thermostatically-controlled equipment 8 are housed in the smoke-box chamber of T type smoke-box assembly 6.Its course of work: during detection, at first start two typhoon machines, produce vertical air curtain at smoke-box two ends of T type smoke-box assembly by left and right sides air curtain blast pipe; The smoke evacuation waste gas of motor vehicle advances mouth from the smoke-box centre of T type smoke-box assembly and enters the smoke-box chamber, the light that the light emitting source of radiating circuit end sends, change a branch of directional light into through the convex lens in the left lens mount, directional light is by the smoke-box chamber of T type smoke-box assembly, converge the back through convex lens in the right lens mount and arrive receiving circuit, be converted to electric signal, it is many more to contain cigarette in the smoke evacuation waste gas, optical energy attenuation was big more when directional light passed the smoke-box of T type smoke-box assembly, and the electric signal that receives is weak more.By comparing the power of received signal, demonstrate measurement data in real time, just can make things convenient for comparatively whether estimating exactly discharges fume meets national standard.
