Abstract
The utility model relates to an in-pipe optical cable fixing device of an optical-cable pipeline safety early-warning system. The in-pipe optical cable fixing device comprises an optical-cable fixing body, wherein an optical-cable installing groove is arranged under the optical-cable fixing body; and magnet grooves are arranged on the optical-cable fixing body at the two sides of the optical-cable installing groove. The in-pipe optical cable fixing device has the advantages that the structure is simple, the design is scientific and reasonable, the use is convenient, the cost is low, no damage to the pipeline is caused, the stability is strong, and the safe and reliable effects are achieved.
Description
Technical field
The utility model belongs to the optical cable fixing device field, optical cable fixing device in especially a kind of pipe of type optical fibre pipeline safe early-warning system.
Background technology
For guaranteeing that PCCP is water supply pipe safe operations such as Prestressed concrete cylinder pipe, steel pipe, generally need pipeline is carried out fracture of wire and Leak Detection.For realizing real-time detection, adopt the distribution type fiber-optic detection system.This system at pipe interior, as sensor, detects local flaw signal with optical fiber along the line with optical cable laying, to reach real-time detection and the purpose of accurately locating.Because optical cable laying in pipe interior, is swung in pipeline under the effect of pumped (conveying) medium for preventing optical cable, the accuracy that influence detects needs with stationary installation optical cable to be fixed on pipe interior.Traditional stationary installation adopts the mode of screw retention mostly, device is screwed at pipe interior, more fixing optical cable.This stationary installation causes certain damage owing to adopt screw retention to pipeline.Under the long term of pumped (conveying) medium, screw is loosening easily, and reliability is low.Simultaneously, the cross-sectional area of this device is bigger, and the impulsive force that receives pumped (conveying) medium is big, and poor stability influences the accuracy of testing result.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art; Optical cable fixing device in a kind of pipe of type optical fibre pipeline safe early-warning system is provided, this fixture structure is simple, design science is reasonable, easy to use, cost is lower, harmless to pipeline, stability is strong.
The utility model solves its technical matters and realizes through following technical scheme:
Optical cable fixing device in a kind of pipe of type optical fibre pipeline safe early-warning system comprises an optical cable fixed body, it is characterized in that: below the optical cable fixed body, be shaped on an optical cable mounting groove, on the optical cable fixed body of optical cable mounting groove both sides, be shaped on the magnet groove.
And described optical cable fixed body both sides are shaped on groove.
And, be shaped on screw on the optical cable fixed body of described magnet groove correspondence.
Advantage of the utility model and beneficial effect are:
1, optical cable fixing device in the pipe of this type optical fibre pipeline safe early-warning system; Comprise an optical cable fixed body; It is characterized in that: below the optical cable fixed body, be shaped on an optical cable mounting groove; On the optical cable fixed body of optical cable mounting groove both sides, be shaped on the magnet groove, this structure has been avoided the fixing infringement to pipeline of conventional screw, has protected pipeline.Use magnet is fixed, and has strengthened the adsorptive power of device, has improved reliability; The also stability of intensifier, smooth streamline-shaped is adopted on optical cable fixed body surface, and the impulsive force that device is received when pumped (conveying) medium flows is minimum; Increased the contact area of device and optical cable simultaneously; Improved stability, the design can make sensing optic cable paste closely on inner-walls of duct, better detects local flaw signal.
2, the utility model is simple in structure, design science is reasonable, easy to use, cost is lower, harmless to pipeline, stability is strong, is optical cable fixing device in a kind of pipe of safe and reliable type optical fibre pipeline safe early-warning system.
