Description
Technical field
The utility model relates to a kind of protective device suitable for surface mount sensor, especially a kind of fiber grating is taken out
Pull-type redundancy box.
Background technique
It is monitored the more universal of application safely to structure with sensor at present.Among these, more situations are in structure
Simultaneously sensor installation is not carried out in construction period, and after structure puts into effect, discovery is pacified safely because extraneous factor influences structure
Full hidden danger needs to mend dress, and such case lower sensor generally requires to be installed on body structure surface.
After sensor is mounted on body structure surface, following problem is exactly to protect to it.Due to fibre optical sensor
Tail optical fiber fusion point need steel pipe to reinforce protection, and facilitate for subsequent maintenance etc. and need reserved part fiber lengths, therefore, optical fiber
The protective cover of sensor needs inside to have sufficiently large space to get well fiber reel and be placed on inside protective device.
Meanwhile the crooked process radius of signal transmission through fiber intensity and optical fiber is closely bound up, fiber kinks can bring signal strength
Loss.Since fibre optical sensor is chiefly used in wide range of structures monitoring, is influenced by transmission range, often occurred because of disk Yu Bao
Fibre loss excessive the problem of causing sensor signal weak or even losing in protection unit, therefore through in entire networking work progress
In be frequently necessary to dismount protective device.
The effect of protection also may be implemented using existing some cabinet protection structures, but in subsequent debugging, maintenance
Dismounting demand it is relatively difficult to achieve.Conventional tank protection structure mostly uses structure with lock or bolt fastening structure, this mechanical connection
It can not open, can only be adopted because lockhole corrosion, screw corrosion cause cabinet to open difficulty even after mode outer long-term placement out of office
With the destructive dismounting mode of opposite violence.
Utility model content
To solve the above-mentioned problems, the purpose of the utility model is to provide a kind of fiber grating drawing and pulling type redundancy box,
It is easy to disassemble that object in cabinet is operated while realizing protection sensor.
The technical scheme in the invention for solving the above technical problem are as follows: a kind of fiber grating drawing and pulling type redundancy box, it
Including box body and cover board, the box body is the cuboid of upper and lower opening, is equipped with extension board, two long sides on the upside of four frames
The middle position of the extension board of frame is equipped with fairlead, and the both sides of the extension board of two long margin frames are respectively provided with a mounting hole,
One of short frame is pull side, and the middle position on the pull side is equipped with a fixation hole；
It is equipped with side plate on the downside of its excess-three frame in addition to pull side, forms a pull in the downside on pull side
Mouthful；The cover board includes panel and snap-gauge connected vertically, and the cover board side is L-shaped；The middle position of the snap-gauge is equipped with
One screw hole, the position of the screw hole and the position of fixation hole are corresponding.
A kind of fiber grating drawing and pulling type redundancy box, the fairlead are in long strip.
A kind of fiber grating drawing and pulling type redundancy box, the size of the panel and the opening face of box body match, the snap-gauge
Size and the frame of box body match.
A kind of fiber grating drawing and pulling type redundancy box, the width of the side plate is at 5 millimeters or more.
Due to the application of the above technical scheme, the utility model have compared with prior art it is following the utility model has the advantages that
The utility model protects sensor using drawing and pulling type body structure, to prevent pull cover board from falling off, is taking out
One section of cover board is drawn to fix using buckle, structure is simply easy to accomplish, easy to disassemble to case while sensor is protected in realization
Internal object is operated.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the utility model box body.
Fig. 3 is the structural schematic diagram of the utility model cover board.
In figure:
Box body 1, cover board 2, mounting hole 3, fairlead 4, fixation hole 5, snap-gauge 6, screw hole 7, pull mouth 8, pull while 9, while
Plate 10.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
Refering to fig. 1-3, a kind of fiber grating drawing and pulling type redundancy box, including box body 1 and cover board 2, the box body 1 are to open up and down
Mouthful cuboid, be equipped with extension board on the upside of four frames, the middle position of the extension board of two long margin frames is equipped with strip
The fairlead 4 of shape, the both sides of the extension board of two long margin frames are respectively provided with a mounting hole 3, and one of short frame is pull
The middle position on side 9, the pull side 9 is equipped with a fixation hole 5.
Be equipped with side plate 10 on the downside of its excess-three frame in addition to pull side 9, the width of the side plate 10 5 millimeters with
On, therefore a pull mouth 8 is formed in the downside on pull side 9；
The cover board 2 includes panel connected vertically and snap-gauge 6, the size and the opening face phase of box body 1 of the panel
Match, the size of the snap-gauge 6 and the frame of box body 1 match, and 2 side of cover board is L-shaped；The middle position of the snap-gauge 6
Equipped with a screw hole 7, the position of the screw hole 7 is corresponding with the position of fixation hole 5.
Working principle:
After sensor is mounted on body structure surface, box body 1 is installed on corresponding body structure surface, reserved fiber reel is good simultaneously
It is placed on inside box body 1, and is drawn from fairlead 4, then cover board 2 is promoted from pull mouth 8, cover the optical fiber light in box body 1
Grid, and it is by screw bolt that snap-gauge 6 and box body 1 is fixed；When needing to debug, repair by fixation between snap-gauge 6 and box body 1
Screw unclamps, and extraction snap-gauge 6 is i.e. detachable.
In addition to the implementation, the utility model further includes having other embodiments, all to use equivalents or equivalent
The technical solution that alternative is formed, should all fall within the protection scope of the utility model claims.
