Description
Technical field
The utility model relates to the miniature air-blowing optical cable of central tubular that the surface has concavo-convex groove.
Background technology
Continuous intensification along with social informatization; The proportion of information interchange amounts such as sound, image and data is increasing; Means of communication in the past can not satisfy present requirement, and advantages such as optical-fibre communications is big with its information capacity, good confidentiality, little, the non-relay segment distance length of volume in light weight have obtained widespread use.The application of optical fiber spreads all over industries such as communication, traffic, industry, medical treatment, education, Aero-Space and computing machine, and to wider darker level development, brings deep effect and change for human life.
The laying method of optical cable is used pneumatic transmission more at present, and promptly a kind of pressurized air that is used to from air compressor is blown into the fiber cable laying technology in the mounted hollow cable tube through blow head with fiber unit.But not too be fit to pneumatic transmission because the diameter of existing optical cable is all bigger with surface structure, so pneumatic transmission length is not very desirable.
The utility model content
In order to overcome the deficiency of prior art; The miniature air-blowing optical cable of the central tubular that provides the surface to have concavo-convex groove; This optical cable simple in structure, diameter is little, in light weight; Reach the purpose that improves pneumatic transmission distance and pneumatic transmission speed through the structure of improving the optical cable outside surface, and can the surperficial lettering of fine protection.
The purpose of the utility model realizes through following technical scheme: the surface has the miniature air-blowing optical cable of central tubular of concavo-convex groove; It comprises a fiber unit and is coated on the sheath on the fiber unit; Fiber unit comprises the loose sleeve pipe of at least one optical fiber and parcel optical fiber, also is filled with the material that blocks water in the loose sleeve pipe, is provided with at least one nonmetal silk ribbon between sheath and the fiber unit; Jacket surface is provided with asperities, is printed on literal on the asperities.
Described nonmetal silk ribbon is a polyester yarn, and one or more in aramid yarn and the glass fiber yarn process, and nonmetal silk ribbon is coated on the fiber unit.
Described asperities and optical cable parallel longitudinal are arranged or vertical angled helical arrangement or positive and negative staggered helical arrangement.
The miniature air-blowing optical cable of central tubular that the surface that the utility model provides has a concavo-convex groove compares with common air-blowing optical cable that to have air-blowing length longer; Advantages such as air-blowing speed is faster; When the maximum outside diameter of two kinds of optical cables is identical; The surface area of common air-blowing optical cable is less than the surface area of novel air-blowing optical cable in the unit length in the unit length, and this optical cable sectional area is less than the sectional area of common air-blowing optical cable, and the air-blowing optical cable mainly receives the effect of following 4 power when air-blowing:
F1: the air-blowing machine is the thrust to optical cable in the microtubule porch;
F2: air-flow and optical cable mantle friction and the power that pulls that forms;
F3: the resistance that optical cable surface and inner-walls of duct friction form;
F4: pipeline the place ahead air pressure is to the resistance of optical cable front end.
Therefore the air-blowing optical cable is at ducted instant stressed F=(F1+F2)-(F3+F4), and wherein, F1 is that the air-flow that air compressor machine produces drives the thrust that air motor forms optical cable, and when output power one timing of air compressor machine, this power can be regarded as constant; F2 is air-flow and optical cable mantle friction and the power that pulls that forms; It is relevant in the friction force that the microtubule surface produces with ducted airshed of entering and air-flow; Because the sectional area of this optical cable is less than the sectional area of common air-blowing optical cable; Therefore when one timing of air compressor machine power, the airshed that when laying this optical cable, gets into pipeline is relatively large; F3 is the resistance that optical cable surface and inner-walls of duct friction form, because two kinds of cable sheath materials are identical, so optical cable is identical with the friction factor that inner-walls of duct produces, but owing to this optical cable is lighter, so the frictional resistance that it receives is also less; F4 is the resistance of pipeline the place ahead air pressure to the optical cable front end, and is relevant less with the profile of these two kinds of cables.There are a lot of concave surfaces on the surface of this optical cable; Its surface area is greater than common air-blowing optical cable surface area, and therefore under the identical situation of sheath material, the surface of contact that air-flow and this optical cable surface produce is bigger; It is relatively large to add airshed above-mentioned, then air-flow to this optical cable produce to pull power bigger; In addition because there are a lot of grooves on the surface of this optical cable; Not only produce friction force in the time of above air-flow acts on; Because the effect of component has produced direct thrust; This just makes this optical cable when air-blowing, can obtain the air-flow thrust bigger than common air-blowing optical cable, can obtain longer air-blowing length and air-blowing speed faster.
The beneficial effect of the utility model is: simple in structure, diameter is little, in light weight, and significantly improved pneumatic transmission distance and pneumatic transmission speed, protected surperficial lettering well; Through test of many times, under test conditions such as same pressure and identical device, the optical cable 1km air-blowing of the utility model can have been shortened more than 25% than ordinary optical cable apart from required time, and maximum air-blowing distance is compared with ordinary optical cable and increased by 30%.
