Abstract
Provided is a fiber probe for detecting electric sparks. The fiber probe is composed of a housing, a support, and a fiber bundle. The housing is a hollow cylinder. An installing hole and a connecting hole are disposed on the support. The housing is fixed in the installing hole. The connecting hole is used for fixing the support near a monitoring area. The fiber bundle comprises multiple sensing fibers which pass through the housing. The end portions of the sensing fibers are exposed outside the housing. The end faces of the multiple sensing fibers are spliced together to form a spherical surface. The fiber probe for detecting electric sparks has a beneficial effect of effectively increasing the coupling efficiency and the area of the monitoring area of the probe of a photoreceptor.
Description
Technical field
The utility model relates to a kind of photo-detector, relates in particular to a kind of fibre-optical probe detecting for electric spark.
Background technology
In many electronic equipments, all there is electric spark phenomenon, for the higher equipment of some precision, the harm of electricity spark phenomenon is very large, if processed not in time, likely causes device damage, if only depend on human eye to monitor electric spark phenomenon, not only require great effort, and have a large amount of blind areas.Electricity spark phenomenon can be attended by electric spark and occur, and electric spark can be luminous, therefore inventor considers to detect by now ripe optical detector technology the light signal that electric spark sends, thereby indirectly help us to judge whether that (this scheme has proposed patented claim separately) appears in electric spark phenomenon; The simplest optical detector technology is connected with photodetector with an optical fiber, if outside has after light coupled into optical fibres, photodetector just has electric signal output, the electric signal of exporting by photodetector, and we just can know exactly and whether occur electric spark phenomenon; And the end face of ordinary optic fibre is generally plane, and generally adopt simple optical fiber to survey, search coverage is very narrow, has monitoring blind area.
Utility model content
For the problem in background technology, the utility model proposes a kind of fibre-optical probe detecting for electric spark, its structure is: described fibre-optical probe is comprised of housing, support and fibre bundle; Described housing be shaped as hollow cylinder; On described support, be provided with mounting hole and connecting hole, housing is fixed in mounting hole, and connecting hole is for being fixed on support near monitored area; Described fibre bundle is comprised of many sensor fibres, and many sensor fibres are set in housing, and the end of sensor fibre is exposed outside housing, the end face of the many sensor fibres formation sphere that is stitched together.
The innovative point of aforementioned schemes mainly contains two, and one forms probe with many sensor fibres, to increase the coupling efficiency of fibre-optical probe to light, its two, make the end face of the many sensor fibres formation sphere that is stitched together, with the monitored area of extension fibre-optical probe, reduce monitoring blind area.Specifically add man-hour, can the outer face integral body of many sensor fibres be polished into sphere by existing optical fiber lapping technique.
Preferably, described housing adopts ceramic material.
In order to increase the transmission mode of fibre-optical probe, preferably, described sensor fibre is multimode optical fiber.
Useful technique effect of the present utility model is: coupling efficiency and the monitored area area that can effectively improve the probe of optical sensor.
Accompanying drawing explanation
Fig. 1, structural representation of the present utility model (being connecting hole shown in mark 4 in figure);
Fig. 2, a kind of concrete application example of the present utility model.
Embodiment
The fibre-optical probe detecting for electric spark, described fibre-optical probe is comprised of housing 1, support 2 and fibre bundle; Described housing 1 be shaped as hollow cylinder; On described support 2, be provided with mounting hole and connecting hole, housing 1 is fixed in mounting hole, and connecting hole is for being fixed on support 2 near monitored area; Described fibre bundle is comprised of many sensor fibres 3, and many sensor fibres 3 are set in housing 1, and the end of sensor fibre 3 is exposed outside housing 1, the end face of the many sensor fibres 3 formation sphere that is stitched together.
Further, described housing 1 adopts ceramic material.
Further, described sensor fibre 3 is multimode optical fiber.
For the ease of those skilled in the art, implement, inventor has also introduced following a kind of concrete application:
The input end of the output terminal of fibre-optical probe of the present utility model and a photodetector (as shown in mark C in Fig. 2) is joined, the output terminal of photodetector and a treating apparatus (as shown in mark D in Fig. 2) are joined, fibre-optical probe, photodetector and treating apparatus have formed an electric spark detection apparatus, it is example that the electric spark of take in travelling-wave tube detects, on the tube wall (as shown in mark A in Fig. 2) of travelling-wave tube, through hole is set, fibre-optical probe (as shown in mark B in Fig. 2) is inserted in through hole, while there is electric spark phenomenon in travelling-wave tube, the light signal being sent by electric spark is collected and transfers in photodetector by fibre-optical probe, photodetector is converted into electric signal by light signal, then photodetector exports electric signal to treating apparatus, when treating apparatus receives after electric signal, electric spark detection apparatus can be judged and in travelling-wave tube, occur electric spark phenomenon, operating personnel can be according to the prompting of electric spark detection apparatus, travelling-wave tube cuts out, to avoid travelling-wave tube, because of electricity, strike sparks and burn out, further, also can directly treating apparatus be connected with the power control part of travelling-wave tube, when there is electric spark phenomenon, by electric spark detection apparatus, controlling travelling-wave tube automatically shuts down, postpone after certain hour, electric spark detection apparatus is controlled travelling-wave tube again and is restarted, thereby realize, travelling-wave tube is carried out to the object of protection automatically.In Fig. 2, only show 2 fibre-optical probes, if travelling-wave tube length is larger, also can further increase the quantity of fibre-optical probe, so that the coverage rate of monitored area is expanded, avoid undetected, each fibre-optical probe needs to configure independently photodetector.
