Description
Technical field
The utility model belongs to self-support cable technical field, and in particular to a kind of night identifiable self-bearing type is multiple anti-
Damaged by rats optical cable.
Background technique
Self-support cable is the optical cable that a kind of itself stiffener can bear self weight and external load, usually in electric power bar
It makes somebody a mere figurehead and uses on tower.Since optical cable is set up in high-altitude for a long time, and to be reduced as far as possible in the enough situations of mechanical strength
Self weight is to prevent optical cable sagging, so multilayer proofing, some even shields in the air will not be generally arranged in self-support cable.But
In country lane, due to being influenced by geographical location and environment, self-support cable can be inevitably connected on near-earth electric pole or
It is to be embedded in underground to lead to every family, and country lanes are the places that mouse ant often haunts, optical cable is bitten by mouse ant
And the case where causing communication bad and fracture, happens occasionally.
In prior art, " one kind can be known at night as disclosed in Chinese invention patent application publication No. CN105700097A
Other optical cable ", including cable core, oversheath, reinforcing element, messenger wire sheath, muscle；The cable core is reinforced by centrally located center
Part, the more Loose tubes except center reinforcemen, the protective layer composition for enveloping more Loose tubes；Have extremely in Loose tube
A few optical fiber；Symmetrically be equipped with two identification strips on messenger wire sheath, the messenger wire sheath of the identical material, oversheath,
Muscle is integrally formed；There is mark band on the oversheath；The identification strip with a thickness of 0.2mm~1.0mm；Identification strip is by spy
Different material is constituted.Its shortcoming is: the noctilucent function of identification strip is easier to cause mouse ant, and internal protective layer is only used for
Leak caused by preventing because of oversheath cracking invades cable core, therefore can not prevent further biting for mouse ant.
In view of the foregoing, it is necessary to which it is simple and have multiple-protection to design a kind of structure, and mouse ant can be effectively prevent to gnaw
The self-support cable stung.For this purpose, the applicant has made beneficial design, technical solution described below is in this back
The energy-saving steam generating device generated under scape.
Summary of the invention
The task of the utility model is to provide for a kind of multiple anti-rat-bite optical cable of night identifiable self-bearing type, is conducive to add
To cable core and identify that the protection and using of item prevents mouse ant from biting optical cable leak, fracture caused by optical cable outer layer and identification item by force
With the adverse consequences such as identification strip is smudgy.
What the task of the utility model was performed by, a kind of multiple anti-rat-bite optical cable of night identifiable self-bearing type,
It is characterised by comprising: an optical cable ontology, which successively includes a jacket layer from outside to inside, sheath in one, one anti-
Mouse layer, a sheath, a protective layer and the center reinforcemen being separately positioned in protective layer and be centered around center reinforcemen week
The more pieces of cable cores enclosed are provided at least one identification strip on the outer surface of the middle sheath；One messenger wire, the messenger wire are hung including one
Line jacket layer and a messenger wire reinforcing rib；One dowel, the dowel upper and lower ends are connect with messenger wire jacket layer and jacket layer respectively
And it is integrally formed.
In a specific embodiment of the utility model, the identification strip uses identical or different luminous face
Color.
In another specific embodiment of the utility model, the middle sheath, sheath, messenger wire jacket layer and company
Low density polyethylene (LDPE), medium density polyethylene, high density polyethylene (HDPE), polyvinyl chloride, fire retardant polyolefin is respectively adopted in the material for connecing muscle
In any one.
In another specific embodiment of the utility model, the jacket layer is nylon protective layer.
In another specific embodiment of the utility model, the nylon protective layer is transparent nylon.
In a specific embodiment in turn of the utility model, the protection against rodents layer is fibre-reinforced plastics
(FRP) layer.
In the utility model more and in a specific embodiment, the protective layer, center reinforcemen and messenger wire add
Strengthening tendons are respectively adopted metal material and are made.
In the utility model more and then in a specific embodiment, the protective layer, center reinforcemen and messenger wire
Reinforcing rib is respectively adopted nonmetallic materials and is made.
The utility model after adopting the above structure, have the advantages that firstly, since use jacket layer, middle sheath,
Protection against rodents layer, sheath and protective layer carry out the structure of multiple-protection to cable core respectively, and middle sheath is arranged in identification strip
Outside, and the jacket layer made by transparent nylon is set in the outside of identification strip, the fluorescence that such identification strip issues can pass through Buddhist nun
Imperial protective layer externally shines, and this structure can effectively hinder mouse ant and bite to optical cable ontology and identification strip, avoids light
Cable leak, fracture and the ambiguous situation of identification strip occur；Secondly, set item night can self-luminescence, and color is not
Together, the convenient position that each cable core is identified in the environment of night darkness, and setting item in the construction process will not be with ambient
Body, which shines, to rub, and is not easy the destruction that is worn, effectively increases service life；Third, when protective layer, center reinforcemen and messenger wire add
Strengthening tendons are respectively adopted nonmetallic materials and are made, which has lightning protection effect.
