Abstract
The utility model discloses an optical cable clamp for a defense area type optical fiber vibration sensor system, wherein the optical cable clamp is used for fixing an optical cable. The optical cable clamp comprises a foundation support and a clamping apparatus, wherein the foundation support and the clamping apparatus are opposite to each other and are sheet metals; and the two ends of the foundation support are bent outwardly relatively to the clamping apparatus, so that the foundation support is in an arc shape. The two ends of the clamping apparatus and the two ends of the foundation support are fixed in an opposite mode; and the middle portion of the clamping apparatus is bent outwardly relatively to the foundation support to form an optical cable groove corresponding to the optical cable. Compared with the prior art, the technology employed by the utility model enables the optical cable clamp to have the following beneficial effects: the optical cable clamp includes two opposite sheet metals, so that the optical cable clamp is elastic and thus the optical cable is not damaged due to the tight clamping; on the other hand, because the foundation support is in a bending shape, when the optical cable is fixed in the clamp, the middle portion of the foundation support is pressed against the optical cable, so that the optical cable can be fixed firmly and is not moved with the wind.
Description
Technical field
The utility model relates to a kind of ply-yarn drill, relates in particular to a kind of optical cable ply-yarn drill for the defence area type optical fiber vibration sensing system.
Background technology
Fibre Optical Sensor Security alert system is based on the security technique guarding system of optical fiber sensing technology.This system utilizes warning network or the security alerting system of the technique constructions such as laser, Fibre Optical Sensor and optical communication, is a kind of modern defense system with alarm to be monitored in the accident that threatens public security.
This system of defense need to be found the position that fortuitous event occurs in advance, stops crime in order in time drop into strength.Therefore modern technical precaution system requirements must be equipped with the boundary defence means, can carry out Real-Time Monitoring and accurate location to threatening safe event, controls timely the generation of threat event.In these technical measures, the optical fiber safety crime prevention system will embody its vital effect, especially defence area type optical fiber vibration sensing detection system.When described defence area type optical fiber vibration sensing detection system detects, the optical signals laser instrument is delivered into optical fiber, detector is processed the phase place of the light signal that receives, and supposes that sensing optic cable is not subject to the not variation of transmission of any interference or light, and the phase place of light signal will not change yet so; When sensor fibre is moved or during the interference that shakes, the transmission mode of light signal will change, change to detect according to this and disturb occurrence positions, thus the undesired signal of obtaining.
In order to make things convenient for the detection of sensing optic cable, generally sensing optic cable need to be laid on the wall, the inferior place of base plate, the existing technical staff need to use ply-yarn drill that optical cable is close to body of wall etc. and locate, it can not be arched upward or let it flow, particularly, in the situation that execution conditions allow, can consider ply-yarn drill is screwed on body of wall, also can metal wire be fastened by the specific glue that is used for bonding metal and body of wall, yet the excessive optical cable that causes of cable duct that existing optical cable ply-yarn drill tends to occur on the ply-yarn drill is fixing insecure, so that optical cable lets it flow, the perhaps too small tension that causes the optical cable card of cable duct, so that optical cable is subject to larger squeezing action fixedly the time, even the excessive situation of optical cable decay appears so that optical cable deformation damages.Therefore, need a kind of optical cable ply-yarn drill that addresses the above problem.
The utility model content
The purpose of this utility model provides a kind of optical cable ply-yarn drill, and this optical cable ply-yarn drill is used for fixedly optical cable of defence area type optical fiber vibration sensing system, and not only fixed effect is firm, and can not damage optical cable.
For on realizing, purpose is arranged, the utility model discloses a kind of line card of optical cable for the defence area type optical fiber vibration sensing system, be used for fixedly optical cable, should comprise pedestal and the jig that position is relative for the optical cable line card of defence area type optical fiber vibration sensing system, described pedestal and jig are sheet metal, and the two ends of described pedestal with respect to described jig outward so that described pedestal is curved, the two ends of described jig are relative fixing with described pedestal two ends, and outwardly-bent to form the cable duct corresponding with described optical cable with respect to described pedestal in the middle of described jig
Compared with prior art, optical cable ply-yarn drill described in the utility model is two sheet metals that are oppositely arranged, so that this optical cable ply-yarn drill is flexible, the optical cable card can not be got tension and cause optical cable to damage; On the other hand, described pedestal is bending, so that optical cable is when being fixed in the ply-yarn drill, the middle part conflict optical cable of described pedestal so that the fixed effect of optical cable is firm, can not let it flow.
Preferably, described pedestal bending is fan-shaped, and this fan-shaped institute spends more than or equal to 120 the central angle angle.
Preferably, the two ends of described jig are with respect to described pedestal outward.
Preferably, the two ends of described pedestal and jig are equipped with screw, two screws pass respectively described pedestal and jig two ends screw so that described pedestal and jig fix.
Preferably, described pedestal and jig are copper sheet, good springiness.
Preferably, be provided with the bar shaped decorative pattern in the described cable duct.
