Description
Technical field
A kind of self-bearing type anti-rat-bite optical cable is the utility model is related to, belongs to optic communication transmission technique field.
Background technology
Self-supporting tensile elements for the overhead non-metallic optical fiber cables of self-supporting are usually to spin synthetic fibre, these optical cables are after the completion of laying
It can be stung by various muroids and some birds birds and peck invasion and attack, so as to progressively lose self-bearing ability.By the use of glass fiber yarn as
The tensile elements of optical cable, although there is certain protection against rodents ability, are used as self-supporting tensile elements, whole due to itself can't be one
Body, once oversheath is damaged, its self-supporting tensile capacity can drastically decline, and cannot resist the puncture of muroid tooth.Using glass
Glass fiber band mode protection against rodents, its material hardness are limited to thickness, its manufactured optical cable is stiff, and reel stays bending radius
It is especially big, to using and laying brings inconvenience.By adding the chemical protection against rodents mode of pungent element in sheath, not only producing
When can produce a large amount of penetrating odors, pollute surrounding air, seriously affect producers' normal work, while with additive
Progressively spread, rodent-proof characteristic can also decline therewith.
The content of the invention
The technical problem to be solved by the utility model is to provide one kind in view of the deficiency of the prior art certainly
Formula anti-rat-bite optical cable is held, cable configuration setting is rationally simple, and not only the anti-unfirmly closing performance of mouse bite preventing is strong, and self-supporting tensile property is high,
And good bending property, it is easily installed laying.
The utility model is that optical cable technology scheme is used by solving the above problems：Include cable core and oversheath, its
Be characterized in that cable core be provided outside it is anti-bite it is anti-peck splicing layer, it is described anti-bite anti-to peck splicing layer by flat-shaped FRP bars along cable core week
It is spliced to arrangement, anti-bite anti-peck splices layer outer cladding oversheath.
By such scheme, the flat-shaped FRP bars width is 2.0~5.0mm, and thickness is 0.5~1.2mm, and surface is hard
It is Gu smooth.
By such scheme, the thinning flat-shaped FRP bars both sides edge withdraw is in blade-like.
By such scheme, the flat-shaped FRP bars are cured by glass fibre with resin formulations to be formed.
By such scheme, the anti-bite anti-splicing layer of pecking is spliced by flat-shaped FRP bars along cable core circumferential direction close-packed arrays,
Adjacent flat-shaped FRP bars at intervals of 0~1.0mm.
By such scheme, the stranded mode that the flat-shaped FRP bars are twisted with SZ or S is twisted is covered in cable core surface, is twisted section
Away from for 100~500mm.
By such scheme, the inner sheath of cladding cable core is provided between splicing layer in cable core and anti-bite anti-peck.
By such scheme, water blocking yarn waterproof layer is provided between cable core and inner sheath.
By such scheme, the cable core is layer-twisted type cable core or skeleton cable core.
By such scheme, the layer-twisted type cable core is half-dried layer-twisted type cable core, and half-dried layer-twisted type cable core includes nonmetallic
Center reinforcemen and the Loose tube being stranded in around center reinforcemen, are set with optical fiber in Loose tube, and fill fiber paste, outside cable core
Winding, which blocks water to prick yarn or wrap up the band that blocks water, forms water blocking yarn waterproof layer, waterproof layer outer cladding inner sheath.
By such scheme, hawser is provided with out in oversheath and inner sheath.
The beneficial effects of the utility model are：1st, flat-shaped FRP bars are not only firm smooth, but also gather in the outer layer of cable core,
Formed it is effective it is anti-bite it is anti-peck splicing layer, it is difficult by it to prevent damaged by rats and unfirmly closing, muroid using the hardness and puncture ability of itself
Gnaw through and undermine cable core；When a flat FRP bar is bitten, its hard sharp side thorn energy puncture muroid oral cavity, abandons it
Further sting and gnaw, therefore optical cable is possessed the anti-unfirmly closing performance of very strong mouse bite preventing；2nd, flat-shaped FRP bars can be used as self-supporting tensile elements
Combine to form a compound outer jacket with oversheath, the outer jacket not only have it is excellent it is anti-gnaw it is anti-peck performance, but also possess strong
Big tensile capacity and anti-collapse ability, can effectively improve the self-supporting performance of optical cable；3rd, the utility model structure setting is simply closed
Reason, barrier propterty is strong, low manufacture cost, and optical cable is soft, good bending property, easy to use and laying；4th, using physics anti-bite knot
Structure, it is free from environmental pollution easy to make.
Brief description of the drawings
Fig. 1 is the radial structure profile of the utility model one embodiment.
Fig. 2 is the radial structure profile of another embodiment of the utility model.
Embodiment
The embodiment of the utility model is further illustrated below in conjunction with the accompanying drawings.For a kind of half-dried layer-stranding cable, structure is such as
Shown in Fig. 1, include half-dried layer-twisted type cable core, the layer-twisted type cable core includes metalloid core reinforcer 8 and is stranded in non-
Loose tube 4 around metal center reinforcer, Loose tube are 6~12, and water blocking yarn can be wound on metalloid core reinforcer
6, optical fiber 7 is set with Loose tube, and fiber paste is filled, winding, which blocks water, outside cable core pricks yarn or the band 3 that blocks water, then in layer-twisted type cable
Anti-bite anti-peck of core outer cladding splices layer 2, and the anti-bite anti-splicing layer of pecking is spliced by flat-shaped FRP bars along cable core circumferential direction close-packed arrays
Form, adjacent flat-shaped FRP bars at intervals of 0~0.1mm, the flat-shaped FRP bars width is 2.5~3.0mm, and thickness is
0.7mm, and surface is firm smooth.Flat-shaped FRP bars are cured by glass fibre with resin formulations to be formed.The flat-shaped FRP bars with
The stranded mode that SZ is twisted is covered in cable core surface, twisting pitch 300mm.With cable core with length, centre does not have single flat-shaped FRP bars
Connector.Anti-bite anti-peck splices layer outer cladding oversheath 1.In oversheath and anti-bite anti-peck between splicing layer according to be actually needed can two
Symmetrically discharge each 1 and open column rope 5 in side.
The production method of the present embodiment is as follows：
Half dry type layer-twisted type cable core is first made in the usual way, and pricks yarn or band parcel cable core with blocking water；
Further around wrap it is anti-bite it is anti-peck splicing layer, by flat-shaped FRP bars around being wrapped in outer layer of cable core in a manner of S is twisted or SZ is twisted, and pass through
