Description
Technical field
The present invention relates to a kind of ultraviolet irradiance testing device, especially a kind of ultraviolet irradiance testing device of applying fluorescent magnetic particle flaw detection, belongs to Non-destructive Testing Technique field.
Background technology
Fluorescent magnetic particle flaw detection is current modal a kind of lossless detection method, and its principle is to need detected workpiece after magnetization, and defectiveness place can produce the accumulation of magnetic and form magnetic trace.MPI fluorescent magnetic particles particle is wrapped with fluorescent material, can send the most responsive yellow-green fluorescence of human eye under ultraviolet ray is irradiated, thereby testing staff can observe magnetic, assembles the magnetic trace forming, and further judges the defect of workpiece.The ultraviolet uv radiation intensity of irradiation is depended in the brightness that the fluorescent material of MPI fluorescent magnetic particles particle outer wrapping sends the visible yellow-green light of human eye, and meter uv radiation intensity is larger, and the fluorescence Yue Liang， Vietnamese side that magnetic sends just detects the defect of workpiece.Therefore, uv radiation intensity is the most important factor that Non-Destructive Testing fluorescent magnetic particle flaw detection affects MPI fluorescent magnetic particles magnetic particle indications, is therefore one of most important factor affecting fluorescent magnetic particle flaw detection quality.
At field of non destructive testing, in MPI fluorescent magnetic particles characterization processes standard, the uv radiation intensity of used uviol lamp is had to clear and definite requirement.Therefore, need regularly the uv radiation intensity situation of UV-lamp to be tested, be defined in apart from the ultraviolet beam center of ultraviolet light source 380～400mm simultaneously and test its uv irradiance.According to the applicant understood, the uv radiation intensity of ultraviolet beam diverse location has very big difference, at present generally when carrying out uv radiation intensity test, tester be all the probe of ultraviolet radiation meter of test is hand held in, put into that ultraviolet is intrafascicular to be measured, in the time of can not guaranteeing read test data, probe meets technological standards requirement from the distance of ultraviolet light source.Meanwhile, because measuring sonde is different in the intrafascicular position of ultraviolet each time, there is the poor shortcoming of comparability in the data of measuring each time, can not reflect the irradiance situation of uviol lamp.
Summary of the invention
The object of the invention is to: the shortcoming existing for above-mentioned prior art, proposes a kind of ultraviolet irradiance testing device simple in structure, easy to carry.
In order to reach above object, ultraviolet irradiance testing device of the present invention contains support, its improvements are, described support is the tripod being comprised of three feets, the top of described tripod is provided with the first fixture of placing uviol lamp, and the bottom of described tripod is provided with the second fixture of placing ultraviolet radiation meter probe.Thereby formed light, stable ultraviolet irradiance testing device.
The present invention further improves, and the bottom of described the first fixture is hollow circular ring, at the excircle of described annulus, is shaped with annular rib straight up, and described rib internal diameter is greater than the diameter of described uviol lamp, forms clearance fit).Can make like this uviol lamp stable placement on device of accident examination, and ultraviolet beam is not stopped irradiation down.
The present invention further improves, and on described annulus, near outer edge place, is evenly shaped with three inclined holes, and described inclined hole matches with the screw thread that is located at feet top, thereby realizes the installation of ultraviolet irradiance testing device and disassemble.
The present invention further improves: described the second fixture is comprised of the three supports cylindrical shell middle with being fixed on three supports being connected with feet, in described cylindrical shell, can pop one's head in by fixed placement ultraviolet radiation meter, thereby realize the stable placement of ultraviolet radiation meter probe, colleague's placement location is fixed, because uviol lamp is stable, place again, in the time of can realizing the each test of probe, in the intrafascicular position of ultraviolet, fixing and relative and distance ultraviolet light source is fixed, thereby realizes comparability and the reliability of each test data.
The present invention further improves again, and the outer end of described support is shaped with internal thread hole, and described feet is shaped with support junction the horizontal through hole being connected with internal thread hole by bolt, can facilitate like this installation of ultraviolet irradiance testing device and disassemble.
In a word, beneficial effect of the present invention is: proving installation is simple in structure, easy to use, volume is little, and it is convenient to carry, while testing at every turn, the probe placement of ultraviolet radiation meter is at the same position of device, fix with the distance of uviol lamp, can effectively guarantee the data consistent that test obtains and stablize, improved accuracy of measurement.
