Description
Technical Field
The invention belongs to the technical field of communication equipment, and particularly relates to an optical fiber distribution cabinet.
Background
With the development of power communication, communication equipment of a transformer substation is gradually improved, and in the communication equipment, an optical fiber distribution cabinet plays a crucial role, and the optical cable can be jumped in the optical fiber distribution cabinet, so that service transmission between stations is realized.
In optical transmission, the information communication of two stations is connected through an optical cable, if direct communication with a third station is required, a jump fiber is required to be switched on an optical distribution, and then the optical distribution is connected with an optical machine, and the optical distribution is also required to be jumped on the optical connection with the optical machine. Generally, the jump fiber is long, the jump fiber is inserted into the optical port, a certain length is properly reserved, the bending angle specified by a communication regulation is kept, redundant jump fibers are coiled in the optical fiber distribution middle fiber coiling column, the jump fiber is more and more along with the development of communication service, and the optical fiber coiled by the fiber coiling column is more and more. Patent document of grant publication No. CN105607199B discloses an optical fiber distribution frame, including the distribution frame body, the front end surface and the back surface of distribution frame body are equipped with wire outgoing slot and inlet wire groove respectively, and the joint has optical fiber jumper wire connector in the wire outgoing slot, and optical fiber jumper wire connector is connected with quartz glass optic fibre, and the inboard middle part of distribution frame body sets up and is no less than two pivots, and the wire reel that a plurality of gradable adjusted is cup jointed in the outside of pivot. This optical distribution frame can realize the hierarchical regulation of wire reel, and the user can the manual selection needs pivoted wire reel, and the convenience is accomodate optical fiber cable more regular, but because optic fibre has certain hardness, stable wire winding can't be realized to conventional wire reel.
In addition, in order to facilitate the searching work of the optical fiber in the operation and maintenance process, there are mainly three methods:
1. label the patch on the patch cord to indicate the address direction. But some services are less, no tag machine is arranged on the site, and the tag machine is not supplemented in time after the fact; sometimes, the staff is relatively lazy, and the label is labeled in lazy mode, so that great hidden danger is left for later optical fiber searching.
2. Drawn directly on the inner wall of the door. The method also has some problems, such as a large number of construction people, different writing methods for each person, and difficult braid splitting due to poor writing. The pens used are different, the possibility of fading exists after a long time, time is consumed, the position drawn on the inner wall of the original box door needs to be changed along with service change sometimes, and the destination of the optical fiber is difficult to recognize after the change for many times.
3. Directly printing high-quality paper and sticking the paper to the inner wall of the box door. Therefore, time and labor are saved, and the later maintenance and search are not changed if the paper is faded or degummed.
4. The front coiling method of workers is different, the coiling weight is different, sometimes the jumping fiber is coiled very tightly, and the cross winding phenomenon exists in the fiber coiling process.
If the optical distribution needs to be verified on site, recording a table of three figures and four tables; or the optical path is in fault and needs to be processed immediately, the substation jumping fiber is generally a single-mode fiber, the color is general color-yellow, the direction of the optical fiber cannot be simply judged through the color, the optical fiber needs to be checked from one end of the jumping fiber to the other end along the optical fiber, a large number of optical fibers are wound on a fiber winding column, the optical fiber is difficult to manage from head to tail, the jumping fiber can be pulled out to cause communication interruption in case of excessive force, if the optical fiber ribbon is used for production service, such as dispatching automation service or relay protection service, serious liability accidents such as circuit and transformer burnout can occur, and the like, and because the tail fiber and the using method thereof are unreasonable, hidden troubles are brought to the subsequent safe production. Patent document No. CN203981931U discloses a shared co-building optical fiber main distribution frame, which includes an optical fiber main distribution frame body, a plurality of trunk integration disks with different colors and a plurality of distribution integration disks are installed on the front surface of the optical fiber main distribution frame body, a plurality of optical splitters are installed on the back surface of the optical fiber main distribution frame body, and the input ends of the optical splitters and the ports of the trunk integration disks, and the output ends of the optical splitters and the ports of the distribution integration disks are directly connected through jumping fibers. This structure adopts the integrative dish of colorful trunk and the integrative dish of a plurality of wirings, but does not follow the differentiation of solving jumping the fine, is unfavorable for the quick seek of optic fibre.
Disclosure of Invention
In view of the above, an object of the present invention is to provide an optical fiber distribution cabinet, which is configured to define a group of winding posts arranged vertically by a specially designed winding mechanism, and wind the same group of optical fibers on the same group of winding posts, so as to facilitate reasonable winding of redundant optical fibers, facilitate troubleshooting, greatly increase the speed of finding, and shorten the time for fault handling.

thereby improve the regularity of jumping fibre in the switch board, the maintainer of being convenient for is checked fast. It is to be noted that: when the length of the optical fiber does not reach the requirement of winding or looping, the limiting plate and the arc-shaped guide plate can be independently used for limiting the middle part of the jumping fiber.
3. In addition, because this device adopts colorful fiber connection, and adjacent optic fibre adopts great colour difference, if the ray apparatus finds to report an emergency and asks for help or increased vigilance, test through the optical power meter, it is that certain optic fibre attenuates greatly or is destroyed by external force, causes the interrupt, and the on-the-spot optic fibre that needs to be changed, just at this moment can be according to the colour of the optical fibre that has a fault, the opposite end is found very fast, this kind of condition divide into following three kinds again:
first, after testing, when the optical fiber is high in attenuation, the optical fiber is found to be connected with the optical machine through simple searching, which shows that the optical fiber needs to be replaced, only the jumping fiber of the optical distribution section needs to be pulled out, and two other optical fibers without faults are plugged in.
And secondly, tests show that the optical fiber has high attenuation, the optical fiber is connected with another optical cable through a jump fiber, two optical cables need to be replaced to corresponding optical fibers according to habits, and the jump fiber is pulled out and inserted into corresponding optical distribution.
Thirdly, after testing, when the optical fiber is damaged by external force, the optical fiber is interrupted, in this case, all the optical fibers of the optical cable are interrupted completely, whether the two stations are double-loop or not is judged, if another optical cable is arranged, the service can be automatically transferred away, and if the other optical cable is not looped, the operation and maintenance staff can only be informed to the site for fusion splicing treatment.
Adopt the optic fibre distribution cabinet of this application, can effectively improve the efficiency of maintenance in-process.
