Description
Technical field
The utility model belongs to the optical fiber technology field, is specifically related to a kind of stringer of vibration-sensing optical cable.
Background technology
Optical fiber sensing technology is because its geneogenous advantage is widely applied, and at boundary defence, progressively promote and come by the safety precaution such as long distance oil-gas pipeline monitoring field as an application direction of optical fiber sensing technology for the optical fiber vibration sensing.Due to the Bottleneck Restrictions that is limited by the electronic technology precision, the distance sensing of modern vibration optical fiber and positioning accuracy are very limited, only have tens kilometers.The various place areas of monitoring that need of modernization are increasing on the other hand, and the effective area of monitoring defence simultaneously again can not be too small.Reduce simultaneously the length of sensor fibre for adapting to the monitoring demand, the utility model proposes a kind of stringer of high-precision optical fiber vibration sensing, vibration optical fiber is applied in the enclosure wall border guard system.
The utility model content
The technical problems to be solved in the utility model is to overcome existing defective, proposes the stringer of the vibrating sensing optical fiber that a kind of registration, Real-Time Monitoring continuation stability is strong, the monitored area is large.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
The stringer of vibrating sensing optical fiber, comprise enclosure wall, fixed leg, wire gauze, buckle, sensing optic cable, described enclosure wall top is fixed with equally distributed fixed leg, drawn wire gauze between two adjacent fixed legs, between two fixed legs, there is a fixedly buckle that is fixed on iron wire at the middle part, the sensing optic cable undulate coils in fixed leg and wire gauze, is provided with on the iron wire of wire gauze for the fixing fixedly buckle of sensing optic cable.
Distance between two described fixed legs is 3 meters or 4 meters.
Described fixed leg is for long 60 centimetres, 6 centimetres of diameters, and thickness of pipe wall is greater than the steel pipe of 2 millimeters.
Described wire gauze is that iron wire parallel more than three strands or three strands consists of.
The diameter of described iron wire is 6 to 8 millimeters.
Described fixedly buckle is tilted-putted ellipse, is provided with cable duct along long axis direction, and cable duct both sides have four fixing holes, and fixed card is buckled and also is provided with horizontal iron wire groove.
Compared with prior art, the utlity model has following beneficial effect:
The utility model is realized the function of circumference intrusion alarm.Be cast in the fixed leg on enclosure wall, its function is fixedly wire gauze of one side cylinder, wire gauze and optical cable have been reduced with the amplitude of natural force vibration, on the other hand when a warning defence area generation shakes, fixed leg can stop vibrations to be propagated to adjacent defence area, thereby has improved stability and the setting accuracy of vibration optical fiber.
Be distributed in abreast the wire gauze between fixed leg, the defence height of the enclosure wall of one side energy, fixedly sensor fibre makes it relatively to fix on the other hand, moreover gives sensing optic cable with the vibrations space.
Be distributed in sensing optic cable on wire gauze with the S type, its role is to the perception climbing and cross the vibrations of generation, effectively enlarged sensitive face on the one hand, saved on the other hand valuable cable length (distance sensing of vibration optical cable is limited).
Sensing optic cable is fixed in fixedly buckle on iron wire, plays fixedly sensing optic cable on the one hand, play that on the other hand the vibrations on wire gauze are delivered on sensing optic cable.
