Background technique
The leakage in Pipeline Under Mother Earth road causes that the effusion of oil is quite dangerous to crowd and environment.The oil leaking, by polluted soil and underground water, will set off an explosion when serious, and plant and atmosphere will be produced to serious harm.The leakage of oil also will cause huge economic loss, causes energy waste, affects the Security of energy industry.Therefore, thus be necessary that the minute leakage that detects oil transport pipeline carries out pipeline to overhaul.Traditional electric transducer is point measurement, and existence can not accurately be located, and can not forecast in advance the shortcomings such as leakage hidden danger, rate of false alarm height; Self can produce heat taking electricity as carrier, have disaster hidden-trouble simultaneously.
Model utility content
The purpose of this utility model is to provide a kind of monitoring of leakage device of oil transport pipeline, can accurately locate the accurate location of Pipeline Leak point, and safely and effectively, reliably the leakage of oil transport pipeline is carried out to long-term detection monitoring.
For achieving the above object, the utility model by the following technical solutions, comprise monitoring main frame, the input end of monitoring main frame connects detecting optical cable, the output terminal of monitoring main frame connects warning device, detecting optical cable is laid along below or the side of duct length, and warning device comprises onsite alarming end and remote alarms end.
Preferably, described onsite alarming end adopts audible-visual annunciator, and remote alarms end Adoption Network transfers to computer, mobile phone.
Preferably, described detecting optical cable is laid in the soil of pipeline below 5-10cm or detecting optical cable is laid in the soil of pipeline side 5-10cm.
Preferably, described monitoring main frame is also provided with standby power supply and communication extender, and communication extender is drawn many detecting optical cables.
By above technological scheme, when certain position temperature of oil transport pipeline raises when abnormal, determine that it leaks, thereby by alarm platform output alarm signal, and can accurately locate the accurate location of leakage point, overhaul so that personnel rush for scene in time, as far as possible the waste of natural resources, pollution, the safety of petroleum pipeline and the loss of people's lives and properties to environment are dropped to minimum point.Simultaneously because detecting optical cable itself is not charged, radioresistance and electromagnetic interference, anti-lightning, can in rugged environment, work for a long time, system is simple, rate of false alarm is low, measuring accuracy advantages of higher, both can realize permanent monitoring, greatly reduces maintenance cost.
Brief description of the drawings
Fig. 1 is structured flowchart of the present utility model;
Fig. 2, Fig. 3 are respectively the sectional views of the paving location of detecting optical cable in the utility model.
Embodiment
As shown in Figure 1, a kind of monitoring of leakage device of oil transport pipeline, comprise monitoring main frame 10, the input end of monitoring main frame 10 connects detecting optical cable 20, the output terminal of monitoring main frame 10 connects warning device 30, detecting optical cable 20 is laid along below or the side of duct length, and warning device 30 comprises onsite alarming end 31 and remote alarms end 32.When oil transport pipeline transports oil, for convenient transmission, must ensure its good stickiness, conventionally will give crude oil heating, make its projecting environment.Like this when occurring to leak maybe in the time having people to steal oil, the crude oil leaking out will cause the temperature anomaly of soil below petroleum pipeline.Detecting optical cable 20 is laid along oil transport pipeline, can round-the-clock monitoring oil transport pipeline near soil temperature variations and be sent to monitoring main frame 10.In the time occurring that temperature anomaly changes, monitoring main frame 10 will carry out onsite alarming and remote alarms by the onsite alarming end 31 of warning device 30 and remote alarms end 32.Specifically, monitoring main frame 10 comprises that its working principle is as follows for the light source 11 of utilizing emitted light pulse, for receiving the receiver 12 of echo photon signal, processor 13 for accounting temperature information: the light source 11 of monitoring main frame 10 is to detecting optical cable 20 utilizing emitted light pulses; The receiver 12 of monitoring main frame receives the echo photon signal that light pulse produces in the interior generation Raman scattering of detecting optical cable 20; The processor 13 of monitoring main frame 10 is according to the temperature information of interior generation Raman scattering place of echo photon signal calculating detecting optical cable 20 receiving and by the temperature information obtaining and default alarm temperature comparison, if higher than alarm temperature, send alarm control signal to warning device 30, warning device 30 receives alarm control signal and reports to the police.
Preferably, onsite alarming end 31 adopts audible-visual annunciator, and remote alarms end 31 Adoption Networks transfer to computer or mobile phone.When detecting optical cable 20 detects after the breakthrough of oil transport pipeline, near the audible-visual annunciator this breakthrough will send alarm signal, and guiding maintainer finds this breakthrough and processes.Computer and mobile phone can extract or check temperature data data in real time by network, to respond in time according to the situation of reporting to the police.
Preferably, as shown in Figure 2,3, soil or detecting optical cable 20 that detecting optical cable 20 is laid on below, pipeline medial axis 5-10cm are laid in the soil of pipeline side 5-10cm.Specifically, for newly-built oil transport pipeline, suggestion is laid on detecting optical cable 20 in the soil of 5-10cm below pipeline in pipe laying process, also can just detecting optical cable 20 be integrated in petroleum pipeline early stage in engineering, thereby can reach more preferably monitoring effect.Due to the seepage of oil be along leaktightness of wall of tubes in soil around, the rising that bring temperature will to like this breakthrough and oil transport pipeline soil around, thereby make detecting optical cable 20 monitor rapidly the abnormity point of temperature, send in time guard sign, accurately locate the accurate location of leakage point.Similar ground, for the oil transport pipeline of having completed, lay detecting optical cable 20 at pipeline medial axis side 5-10cm, its height is concordant with duct bottom, once pipeline point leaks, bring the rising of temperature will to pipeline soil around, thereby make detecting optical cable 20 can detect in time temperature anomaly point, and send guard sign, the position of accurately orienting leakage point.
Preferably, monitoring main frame 10 is also provided with standby power supply 50 and communication extender 40, and communication extender 40 is drawn many detecting optical cables 20.Standby power supply 50 can ensure to monitor main frame 20 normal and continuous operation, avoids because occurring that powering-off state affects work.Communication extender 40 can be drawn many detecting optical cables 20 and oil transport pipeline be carried out to online monitoring of leakage simultaneously.
