Embodiment
The embodiment of cable protection pipeline in conduit line in the utility model: as shown in Figures 1 to 10; this protection pipeline is a kind of Combined optical cable protection pipeline laying in cable duct, and it is formed along the docking of fiber cable laying directional combination in cable duct by straight tube assembly 413, winding pipe assembly 414 and blocking component.
Straight tube assembly 413 is formed by connecting by straight tube upper cover 101 and straight tube base 102 make-ups of upper and lower two and half slit bamboo or chopped wood tubuloses, upper cover and base be make-up and surrounding along linearly extended straight tube cable passage mutually, the cross section profile of cable passage is the just round of diameter 100mm, the outer peripheral face of straight tube base and the formed pipeline of straight tube upper cover is prismatic surface, straight tube upper cover 101 and straight tube base 102 are upper and lower symmetry, the length of every joint straight tube assembly 413 is no less than 1500mm, on straight tube upper cover 101 and straight tube base 102, by dig breach in cooperation place, form along straight tube cable channel axis to what extend and tie up tongue piece 108.Wherein the upper notch 105 on straight tube upper cover 101 and the down gap on straight tube base 102 106 are axisymmetric shape, upper breach and lower breach form C type breach after straight tube upper cover 101 and straight tube base 102 make-ups, and upper notch 105 and down gap 106 are the edge that starts from cooperation place, finally tie up tongue piece 108 root dodge breach, the clearing end of dodging breach is blind end, the clearing end of dodging opening is openr than air chamber end, so that it is thicker than root to tie up the projecting end of tongue piece 108, between the binding projecting end of tongue piece and root, there is the gear edge for stoping band to be deviate from from projecting end.The width of breach is 15mm, so that be fixed with nylon cable tie, and difficult drop-off after fixing, and distance between adjacent C type breach is not more than 250mm.The bottom of straight tube base 102 offers a uniform colligation hole 111 of axially spaced-apart that comes cable passage, the long 25mm in colligation hole 111, wide 15mm, the spacing between adjacent two colligation holes 111 is 25mm, so that coordinate with nylon cable tie and straight tube base 102 is tied up and is fixed on cable bearer 405.
The cross section 205 of winding pipe assembly 414 is identical with straight tube assembly 413, the difference of winding pipe assembly 414 and straight tube assembly 413 is: the circular arc body that line 202 radius 250mm centered by the bending part of winding pipe assembly 414, angle are 90 °, meets the requirement that general nonmetal layer-twisted type fire-retardant cable bending radius should be not less than 15 times of cable footpaths; Straight portion 203 length at winding pipe assembly 414 two ends are 200mm; The bend pipe upper cover 201 of winding pipe assembly 414 and bend pipe base 207 are laterally zygomorphic L-type body, upper notch 208 on bend pipe upper cover 201 and the down gap 209 on bend pipe base 207 extend along the corresponding site of its place pipeline, and the colligation hole 211 of bend pipe base 207 bottoms also along the L-type trajectory direction of whole winding pipe assembly 414 uniformly at intervals.
Blocking component consists of shrouding 301 and handle 302, the cylindric lid that shrouding 301 is indent, and the thick 25mm of shrouding 301, diameter are 98mm, are slightly less than the internal diameter of straight tube assembly 413 and winding pipe assembly 414; Handle 302 is for being fixed on the U-bolt in shrouding 301 centres, in the indent position of handle 302 major parts in shrouding 301.
In the present embodiment, protect pipeline to be applicable to be arranged in the conduit line of L-type; cable bearer 405 is fixed on the inner side wall 403 of conduit line; the be laid in position of close root of cable bearer 405 of power cord 412; fiber cable laying is at the projecting end of cable bearer 405; straight tube assembly 413 and the winding pipe assembly 414 of protection pipeline set up along cable bearer 405, to realize closed butt joint.
In the present embodiment the colligation hole of base bottom both can be for base fixing on cable bearer 405, can dispel the heat for draining again.Blocking component is after sealing up the end of protection pipeline, and what can prevent oarse-grained foreign matter and Small Rodents animal enters protection pipeline.Therefore this protection tube road has the following advantages: in modular cable ditch, on the cable bearer 405 of cable protection pipeline in cable duct, be easy to set up the combination simple and fast of inter-module; The anti-damage of structure resistance to compression of assembly, after single component damages, Renewal process is simple and easy, and operating optical cable is had no effect; In pipeline, be difficult for ponding, the destruction to optical cable that enters that can resist Small Rodents animal simultaneously; In pipeline, space is abundant, can lay many optical cables; The curved design radian of protection pipeline is large, and penetrating and extract out all of optical cable easily realizes; Because use amount is larger, consider the anti-aging and Cost Problems of material, pipeline is used COPP material.
In the above-described embodiments, tying up tongue piece is to form by dig breach on upper cover and base, to avoid tying up the low problem of tongue piece space availability ratio overhanging and that cause, in other embodiments, tie up tongue piece and also can be formed by structures such as the outer wall upper overturning at upper cover and base, engaging lugs.
In the above-described embodiments, that the inside of pipeline is is cylindric, outer peripheral face is prism-shaped, thereby be convenient to the location of pipeline on cable bearer and the location and installation between base and upper cover by periphery prismatic surface, by cylinder endoporus, obtain larger internal capacity, be convenient to threading, in other embodiments, inside and outside prism-shaped, the cylindric or irregular column structure of also can being of pipeline.
In the above-described embodiments, the bottom of base offers colligation hole, so that base is tied up and is fixed on cable bearer, in other embodiments, pipeline also can adopt the web members such as clip, anchor ear, U-bolt to be fixed on cable bearer, and even is directly fixed on cable bearer by forms such as welding, bonding, buckle connections.
