Abstract
The utility model relates to an armoured optical cable used for a stress monitoring system, comprising an optical unit and a sheath cladding the outside of the optical unit, wherein the optical unit comprises a loose bushing, an optical cable contained in the loose bushing and a factice used for optical cables and filled in gaps between optical cables. The armoured optical cable is characterized by also comprising an armoured layer arranged between the optical unit and the sheath, wherein the armoured layer is a steel belt lapping with butt gap on the optical unit. The armoured optical cable used for a stress monitoring system has the advantages of strong pressure resistant performance, good flexibility and excellent susceptibility to the stress change, etc.
Description
Technical field
The utility model relates to a kind of armouring optical cable, particularly a kind of structure that is used for the armouring optical cable of stress monitoring system.
Background technology
In recent years, China so that all over the world disaster such as earthquake, landslide take place frequently, especially along the line at railway, highway the life because event frequencies such as the casualties that disasters such as landslide cause, property loss, passenger's delay take place frequently.But above these disaster majorities all have a process from quantitative change to qualitative change, if monitor the generation of disaster on amplitude by massif is moved, changes, the trend in advance in landslide early stage, dealt carefully with, just can be avoided or reduce the loss that accident causes effectively.
As everyone knows, optical fiber is used for reference the transport property of self, has been widely used in communication field, and optical fiber is except that transmitting the information in fact, and its optical characteristics is also very responsive to the variation of temperature, bending stress, can use for reference in the disaster prevention system.
The utility model content
The purpose of this utility model is to provide a kind of have stronger withstand voltage properties, good pliability, and the armouring optical cable that is used for stress monitoring system of the good susceptibility that changes of counter stress.
For achieving the above object, the utility model provides a kind of armouring optical cable that is used for stress monitoring system, the sheath that it comprises the light unit and coats the outside, described smooth unit, described smooth unit comprises loose sleeve pipe, be housed in the optical fiber in the loose sleeve pipe and be filled in the optical fiber ointment in optical fiber gap, described armouring optical cable also comprises the armor that is arranged between light unit and the sheath, and described armor is that the steel band gap is wrapped on described smooth unit.
Preferably, described sheath is flame-proof polyethylene or flame-proof polyvinyl chloride material.
Preferably, described optical fiber is 1～12 single-mode fiber.
The utlity model has following beneficial effect: armor of the present utility model is that the steel band gap is wrapped on the light unit.This structure has promoted the withstand voltage properties and the product pliability of optical cable product, thereby expands, promoted the engineering application of optical cable product.The good pliability of armouring optical cable described in the utility model and the emergent property of optical fiber, make this armouring optical cable to the good susceptibility that has of the STRESS VARIATION of surrounding environment, can be in disaster prevention system for stress monitoring system provides in time, monitoring information accurately.The utility model can be applicable to railway, highway and reaches along the line in the disaster prevention system in places such as mountain area, can detect disaster or artificial destructions such as landslide, earthquake immediately, avoids causing casualties and property loss.
