Abstract
The utility model relates to a filled optical cable hanging along an inner wall of a sewer. The light unit comprising a metal pipe which contains an optical fiber bundle is wrapped with an internal sleeve layer and the outside of the internal sleeve layer is provided with an armored steel belt layer with a certain gap. A space filling layer reserved between the internal sleeve layer and the armored steel belt layer is filled with a certain compressed air, inert gas or fluid oil. The outermost layer is an external sleeve layer wrapped tightly around the outside of the armored steel belt layer and the light unit is filled with high effective anti-water oil paste. The utility model is widely applied to the optical cable communication field which can be laid along the inner wall of the sewer with the advantages of good moisture-proof and waterproof performance, chemical corrosion resistance, and small animal biting avoiding. The positive pressure of the gas and fluid in the filling layer effectively blocks the corrosion of each harmful gas molecule to the optical fiber in sewer pipes. Through examining the gas or fluid pressure in the filling layer, breakage of the fiber cable suffered from manpower or natural forces can be discovered in early time, and the degree and position of the breakage can be estimated, thereby guaranteeing to transmitting communication signals normally, safely and reliably.
Description
Affiliated technical field
The utility model relates to a kind of communications optical cable, particularly can be along the optical cable of the attached extension of sewer inwall promptly along the filled fiber cable of the attached extension of sewer inwall.
Background technology
Development along with the town and country construction cause, underground or the aerial line resource that is used for laying optical cable is more and more nervous, and as fine as a spider's web sewer pipe network extends in all direction, ubiquitous, laying optical cable will be removed a large amount of municipal administration excavations, landfill executive cost from the single pipeline of these prior function, greatly reduce the fiber cable laying cost, prospect is tempting.But the waste water composition complexity that flows in these pipelines, also have many parasites, therefore the performance that the optical cable that lays in sewer necessarily requires higher waterproof, resistance to chemical attack and anti-toy to nibble, existing optical cable can't reach so high requirement simultaneously.
Summary of the invention
Can not possess the nibble deficiency of all functions of protection against the tide, waterproof, anti-chemical corrosion and anti-toy simultaneously in order to overcome existing optical cable, the utility model provides a kind of optical cable that can lay at sewer, make its can protection against the tide, toys such as waterproof, anti-chemical corrosion and anti-mouse nibble.
The technical scheme in the invention for solving the technical problem is: a kind of can be along the filled fiber cable of the attached extension of sewer inwall, constitute by coating inner restrictive coating, packed layer, armouring tape sheath and external sheath layer outside the light unit, coat one deck inner restrictive coating outside the light unit that it is characterized in that constituting by the metal tube that includes fibre-optic bundle; Inner restrictive coating is outer with certain interval pine cover one armouring tape layer, the space of leaving between inner restrictive coating and the armouring tape layer is inflation or oil-filled packed layer, outermost layer is the external sheath layer of hard-pressed bale outside the armouring tape layer, the protection tube of above-mentioned described formation light unit is stainless steel, copper, aluminium or other suitable metal tube, make by welding of various suitable thermals source such as laser, plasma or electricity or seamless extruding, in fibre bundle is inserted pipe in the efficient greasy for preventing water of filling; Pressurized air, inert gas or the fluid oil with certain pressure filled in the above-mentioned described inner restrictive coating outside and the packed layer space between the armouring tape layer inboard, degree and position damaged and estimation breakage in view of the above that the pressure by detecting gas in the packed layer or fluid oil can the early detection optical cable be caused by manpower or natural force; The steel band of above-mentioned described armouring tape layer is can be in case the wrinkle steel band or the stainless steel band of the single or double plastic-coated that toy is nibbled, zinc-plated or chromium plating; Above-mentioned described inner restrictive coating and external sheath layer are the nonmetallic materials of tygon, Polyvinylchloride, polypropylene, fluoroplastic or the anti-chemical corrosion of other suitable water-proof sealing.
The beneficial effects of the utility model are to possess the function that toys such as moistureproof and waterproof resistance to chemical attack and anti-mouse are nibbled simultaneously, the gas in the packed layer or the malleation of fluid hinder shelves effectively in the sewer pipe various harmful gas molecules to the erosion of optical fiber, pressure by gas or fluid in the detection packed layer, can the early detection optical cable suffer manpower or elemental cause damaged and damaged degree and the position of estimation in view of the above, thus guarantee fiber cable laying can be normally in sewer transmit communications signals safely and reliably.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model cross-sectional view.
In Fig. 1: 1. fibre-optic bundle, 2. efficient greasy for preventing water, 3. stainless-steel tube, 4. inner restrictive coating, 5. packed layer space, 6. armouring tape layer, 7. external sheath layer.
Embodiment
A kind of can be along the filled fiber cable of the attached extension of sewer inwall, constitute by coating inner restrictive coating, packed layer, armouring tape sheath and external sheath layer outside the light unit, coat one deck inner restrictive coating outside the light unit that it is characterized in that constituting by the metal tube that includes fibre-optic bundle, inner restrictive coating is outer with certain interval pine cover one armouring tape layer, the space of leaving between inner restrictive coating and the armouring tape layer is inflation or oil-filled packed layer, and outermost layer is the external sheath layer of hard-pressed bale outside the armouring tape layer.The protection tube of above-mentioned described formation light unit is stainless steel, copper, aluminium or other suitable metal tube, make by welding of various suitable thermals source such as laser, plasma or electricity or seamless extruding, in fibre bundle is inserted pipe in the efficient greasy for preventing water of filling; Pressurized air, inert gas or the fluid oil with certain pressure filled in packed layer space between the above-mentioned described inner restrictive coating outside and the armouring tape layer inboard; The steel band of above-mentioned described armouring tape layer is can be in case the wrinkle steel band or the stainless steel band of the single or double plastic-coated that toy is nibbled, zinc-plated or chromium plating; Above-mentioned described inner restrictive coating and external sheath layer are the nonmetallic materials of tygon, Polyvinylchloride, polypropylene, fluoroplastic or the anti-chemical corrosion of other suitable water-proof sealing.The gas in the packed layer or the malleation of fluid hinder shelves effectively in the sewer pipe various harmful gas molecules to the erosion of optical fiber, by detecting the pressure of gas in the packed layer or fluid, can the early detection optical cable suffer that manpower or natural force cause damaged and damaged degree and the position of estimation in view of the above.
