Direction is equipped with the handle hole 7 intersected with pawl 6, and handle hole 7 is arranged through pedestal 3, when the desired pawl 6 that releases is to ratchet bar 5
After limit, it is only necessary to be inserted into rod piece into handle hole 7, under pawl 6 is pushed up, pawl 6 is separated with ratchet bar 5, can be released
The disassembly of bottom plate 4 and pedestal 3 is realized in limit of the pawl 6 to ratchet bar 5, facilitates the position of adjustment detection optical cable 2 in installation process
It sets.
Referring to Fig.1 and Fig. 2 is set on pipeline 1 along detection 2 distribution arrangement of optical cable to realize the protection of detection optical cable 2
There is the unwrapping wire slot 11 for mounting fixing parts 8 and optical fiber, unwrapping wire slot 11 moves towards setting according to detection optical cable 2, in unwrapping wire slot
It is equipped in 11 and unwrapping wire slot 11 is being filled to full bonding agent after the installation is completed, after installing, bonding agent can be by unwrapping wire slot
11 fill up, and such bonding agent can will test optical cable 2 and coat completely, to shield to detection optical cable 2, keep away
Exempt from the liquid in use process in pipeline 1 detection optical cable 2 is caused to damage.
The implementation principle of the present embodiment are as follows: when installation, first pedestal 3 is fixed in unwrapping wire slot 11, then by bottom plate 4 and
Pressing plate 41 is removed from pedestal 3, bottom plate 4 and pressing plate 41 is fixed on outside detection optical cable 2, after fixed, again by bottom plate 4
It is installed on pedestal 3, sliding floor 4, the ratchet bar 5 on bottom plate 4 is contacted with the pawl 6 in T-slot 31 and slides bottom
Plate 4 to detection optical cable 2 is tightened.
Embodiment two:
A kind of installation method of detection device, comprising the following steps:
Step S1: alignment is first drawn lines in 1 surface unwrapping wire of pipeline using print cartridge, draws predetermined laying-out, route is along 1 axis of pipeline
Keep straight to part direction is laid, route circumferentially lays part direction and guarantees to be circle, can by the way of print cartridge setting-out
There is rough planning with the trend to detection optical cable 2, improves the accuracy in process of deployment.
In step sl, for the pipeline 1 being laid with using open cut mode, detection optical cable 2 is arranged on 1 outer wall of pipeline；It is right
In the pipeline 1 being laid with using tunneling mode, detection optical cable 2 is arranged on 1 inner wall of pipeline, selects to examine according to specific condition of construction
The paving location for surveying optical cable 2, not only facilitates operation, but also save the cost, since 2, optical cable needs of detection are contacted with pipeline 1, i.e.,
Detection can be achieved, therefore will test optical cable 2 and be arranged in 1 outer wall of 1 inner wall of pipeline or pipeline, shadow can't be caused to detection process
It rings.
Step S2: polishing polish the unwrapping wire slot 11 that width is 3-5cm along the selected route of mark by electric grinding machine
, in case detection optical cable 2 is laid and installed, in the present embodiment, the width of unwrapping wire slot 11 is preferably 3cm, according to embedded detection optical cable 2
Radical selects suitable 11 width of unwrapping wire slot.
Step S3: dedusting clears up the ash in unwrapping wire slot 11 using cleaner, and cleaner can be using electricity
Dynamic hair dryer, the ash in unwrapping wire slot 11 is blown out, to guarantee the contact area of subsequent bonding agent Yu unwrapping wire slot 11, is improved viscous
Connect the fixed effect of agent Yu unwrapping wire slot 11.
Step S4: unwrapping wire will test optical cable 2 and be placed into unwrapping wire slot 11 along 11 length of unwrapping wire slot, and along detection optical cable 2
Length direction lays fixing piece 8, and pedestal 3 is fixed in unwrapping wire slot 11, and bottom plate 4 and fixing piece 8 are installed to outside detection optical cable 2
Portion and fixed with detection optical cable 2, then will be in the T-slot 31 on 42 inserted base 3 of T-shaped block on bottom plate 4, naturally it is also possible to
Detection optical cable 2 is fixed using other fixed forms, such as using modes such as welding.
Step S5: after detecting the laying of optical cable 2 and finishing and be tensioned, carrying out comprehensive paste operation, along laying-out, with viscous
Patch is filled unwrapping wire slot 11, and fixing piece 8 and detection optical cable 2 are covered all, i.e., filled and led up unwrapping wire slot 11, in this way
The drainage works of pipeline 1 will not be impacted.
Step S6: lay detection 2 outlet of optical cable protection, will test the fibre core in optical cable 2 be converted into wire outlet part it is high-strength
The armored optical cable of degree carries out protection extraction, not only improves the fixed effect of detection optical cable 2, while being convenient for subsequent cable connection.
In addition, between step S4 and step S5, increasing step S41: pre- to improve the detection effect of detection optical cable 2
Draw, the laying trend of installation detection optical cable 2, the successively bottom plate 4 on sliding bottom 3, pawl 6 abutted with ratchet bar 5 to bottom plate 4 into
Row limit, the detection optical cable 2 between adjacent fixing piece 8 is tensed, optical cable 2 is will test and carries out pre- pulling process, can to avoid because
Detect the relaxation Bending Influence later period test effect of optical cable 2.
Finally, in step s 5, increasing step S51, when bonding agent filling finishes and then use hair drier thermalization glue
Body makes to detect optical cable 2 and the well-bonded fixation in 1 surface of pipeline, and hair drier can accelerate the fixed-type of bonding agent, protect simultaneously
The fixed effect for having demonstrate,proved bonding agent improves the structural strength of bonding agent.
The embodiment of present embodiment is presently preferred embodiments of the present invention, not limits protection of the invention according to this
Range, therefore: the equivalence changes that all structures under this invention, shape, principle are done, should all be covered by protection scope of the present invention it
It is interior.
