The three bundle end of the optical fiber bundle is plugged into the three via holes of the front end of the optical fiber connecting head, the one bundle end of the optical fiber bundle extends out of the optical fiber connecting head through the via hole of the rear end of the optical fiber connecting head, and two end parts of the optical fiber bundle are respectively connected with optical fiber end heads. Parts, positioned between the optical fiber end heads and the optical fiber connecting head, of the optical fiber bundle are sleeved with soft tubes. According to the optical fiber, optical signal transmission of the optical fiber can be ensured, maintenance cost can be lowered, on-site operation is simple, convenient maintenance is realized, and the problem that conventional optical fibers are easy to damage and are complex in on-site maintenance can be well solved.
Description
Technical field
The utility model belongs to flame detection technique field, particularly, relates to a kind of flame detecting optical fiber.
Background technology
Optical fiber is in the time gathering light beam, due to a large amount of radiation heat and the heat by conduction of fiber-optic component fixing to optical fiber that produce when fuel combustion in boiler, easily cause optical fiber to come unstuck, burn or the logical light rate of optical fiber under degradation phenomenon, cause flame detector to produce the final boiler shutdown without fiery signal, cause heavy losses to power plant.Meanwhile, because manpower maintenance cost increases year by year, therefore, effectively protect optical fiber to lead to light rate, extended fiber serviceable life, adopt rational structure, optical fiber easy to maintenance is very important.
But, using at present the structure of optical fiber, be mainly one-in-and-one-out type optical fiber, once optical fiber damages, fire inspection just can not normal inspection, causes fire inspection field maintemance work increase.
Utility model content
The purpose of this utility model is to provide a kind of flame detecting optical fiber, and described device can ensure optical signal transmission fiber effectively, reduces maintenance cost; Execute-in-place is simple simultaneously, is convenient to safeguard, thereby solves preferably the problem that optical fiber is fragile, field maintemance is complicated.
For achieving the above object, the utility model mainly adopts following technical scheme:
A kind of flame detecting optical fiber, comprising: fibre bundle, and its one end is three beams, the other end is a branch of; One fiber connector, be shaped as cylinder, middle part offers cavity, its front end arranges three through holes, rear end arranges a through hole, fibre bundle is three through holes that one end of three beams is inserted in respectively described fiber connector front end, and fibre bundle is that a branch of other end extends described fiber connector by a through hole of fiber connector rear end; End, described fibre bundle two ends is connected with optic fibre end respectively; The position of described fibre bundle between optic fibre end and fiber connector is arranged with flexible pipe.
Wherein, one end that described fibre bundle is three beams in fiber connector cavity by high-temperature plastic mutually bond form a branch of.
Again, end, described fibre bundle two ends is connected with optic fibre end respectively by high-temperature plastic.
And described high-temperature plastic is 510 high-temperature plastics.
Again, described optic fibre end outside surface is respectively arranged with screw thread.
Again, three of described fiber connector front end through holes are the arrangement of " product " font or are radially arranged in parallel.
And described flexible pipe is metal hose.
Compared with prior art, the utility model beneficial effect is:
1) fibre bundle one end is set to three beams, thereby the fibre bundle quantity of signal input part is expanded to 3 bundles; The fibre bundle other end coordinates the use of fiber connector, by gluing three beams be a branch of, thereby a branch of as a whole fibre bundle output signal, thereby realize three settings of entering a removing from mould optical fiber, avoid because single optical fiber bundle damages the whole inoperable situation of optical fiber afterwards;
2) the sheathed flexible pipe in the position of fibre bundle between optic fibre end and fiber connector, can realize the exposed aerial part of fibre bundle is protected, and prevents that fibre bundle is exposed in air, easy-to-dismount prevent simultaneously fibre bundle damage;
3) fibre bundle two ends arrange optic fibre end, and realization is fixing to fibre bundle, and then ensure the stable transfer of signal;
4) fibre bundle two ends end face all applies high-temperature plastic, prevents high temperature damage fibre bundle.
