Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation of optics air chamber wipe-off type dust arrester in the utility model embodiment gas detect;
Fig. 2 is motor-driven Wiping device schematic diagram in Fig. 1;
Fig. 3 is the structural representation of optics air chamber wipe-off type dust arrester in another embodiment gas detect of the utility model;
Fig. 4 is the Wiping device schematic diagram that in Fig. 3, mechanical clockwork spring drives.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in figures 1 and 3, in the utility model gas detect, optics air chamber wipe-off type dust arrester comprises two seal chambers, be arranged on the both sides of air chamber, optical mirror slip 13 for reflects laser is all installed in two seal chambers, laser fiber interface 11 and detector 14 are arranged in same seal chamber, or are separately positioned in two seal chambers.
In an embodiment of the present utility model, laser fiber interface 11 and detector 14 are separately positioned in two seal chambers.As shown in figures 1 and 3; the inwall at two seal chamber two ends all installs the optical mirror slip 13 for reflects laser; laser fiber interface 11 is embedded above the optical mirror slip 13 of one of them seal chamber; embed detector 14 below the optical mirror slip 13 of another seal chamber, realize the proofing dust and protecting to optical device by seal chamber.The position of laser fiber interface 11, detector 14 and optical mirror slip 13 can be arranged as required, is not limited to above-mentioned setting.
The end face that two seal chambers are relative all has window, window is installed transparent glass 12, high light transmittance glass can be adopted, make light loss-free through.
Although adopt high transparent glass can ensure the clean of laser instrument and detector, the good material (as high light transmittance glass) of the light transmission as protection was passed along with the working time, surperficially also can pile up a large amount of dust, affected optical detection.Therefore, at transparent glass 12 arranged outside Wiping device, regularly wiping can be carried out to transparent glass.
Cover Air Filter 40 at the outside surface of whole optics air chamber, both can intercept the dust of larger particles, can ensure that again gas to be detected can enter in open air chamber smoothly, be convenient to optical detection.
The inwall at each seal chamber two ends is provided with optical mirror slip 13, for the laser that multiple reflections comes via optical fiber interface 11, finally be detected device 14 to receive, gas with various has different absorption spectrums to infrared light on respective specific wavelength, via the laser of laser fiber interface 11 place's incidence, time consistent with the absorption spectrum of gas to be measured, gas to be measured in air chamber can produce this incident light and absorb, because the characteristic spectrum absorption intensity of gas is relevant with the concentration of gas, therefore, can detect because absorbing the light intensity attenuation produced at detector 14 end, thus be finally inversed by the concentration of gas.
In an embodiment of the present utility model, as depicted in figs. 1 and 2, Wiping device comprises motor 21, eccentric wheel 23 and windscreen wiper 24, connection for transmission axle 22 between motor 21 and eccentric wheel 23, and eccentric wheel 23 drives windscreen wiper 24 cleaning glass window 12 back and forth.
In another embodiment of the present utility model, as shown in Figure 3 and Figure 4, Wiping device comprises mechanical type clockwork spring 31, eccentric wheel 33 and windscreen wiper 34, and mechanical clockwork spring 31 is connected by axle 32 with between eccentric wheel 33, and eccentric wheel 33 drives windscreen wiper 34 to do periodic swing.
Wiping device is applied to optics air chamber by the utility model, and structure is simple, and handling ease is easy to maintenance, with low cost, and better dust removal effect.Because precision optics measures the strict demand to environment, many measurements can only be carried out in laboratory, and the utility model is transformed on the basis of ordinary optical air chamber, there is good environmental suitability, the reliability and stability that engineering site is measured can be ensured very well.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to the utility model claims.
