Abstract
The invention relates to a transmission pipeline capable of remotely monitoring leakage, which comprises a plurality of sections of pipelines which are mutually connected. The transmission pipeline is characterized in that the pipe wall of each section of pipeline in a plurality of sections of pipelines is a closed interlayer; a sensor capable of detecting transmitted fluid is arranged in each closed interlayer; and the sensors are electrically connected with GPRS (General Packet Radio Service) wireless data transmission units in the interlayers or on the outer walls of the interlayers. The transmission pipeline can be used for timely, reliably and remotely detecting the leakage of the pipeline, has low detection cost and is easy to popularize.
Description
Technical field
The present invention relates to a kind of conveyance conduit, relate in particular to a kind of conveyance conduit that can remote monitoring seepage.
Background technique
At present, the Leak testtion of conveyance conduit is mainly contained to two classes both at home and abroad.The one, on the way pipeline is detected because of the microvibration that carried liquid or Leakage Gas produce by manually carrying instrument, and then judge whether to exist and leak; Need to quietly carry out night, can not find timely to reveal, and workload be large, cost of labor is high.The 2nd, by pipeline on the way, a large amount of isoparametric sensors of flow, pressure, liquid level, temperature of installing, laying the detection fluid of carrying, and by the data transmission of these sensors to central processing system (CPS), carry out comprehensive analysis and judgement, judge the abnormal parameters of surveying, assert that pipeline exists leakage.But due to pipeline distribution complexity, the fluid-phase mutual interference between adjacent conduit is large, and carry the parameter such as flow of fluid to be subject to the interference of various extraneous factors, be also difficult to Control and elimination, the reliability of its testing result, poor accuracy; Needed various number of sensors is huge, and testing cost is high.
Summary of the invention
Object of the present invention is just to provide a kind of conveyance conduit that can remote monitoring seepage, and this kind of conveyance conduit can be in time, remote detection goes out the seepage of pipeline reliably, and testing cost is low, is easy to promote.
The present invention realizes the technological scheme that its goal of the invention adopts, a kind of conveyance conduit that can remote monitoring seepage, comprise interconnective more piece pipeline, it is characterized in that: the tube wall in every pipe joint road of described more piece pipeline is the interlayer of sealing, in the interlayer of sealing, the sensor that can detect the fluid of carrying is installed, sensor is electrically connected with the GPRS wireless data transmission unit in interlayer or on interlayer outer wall.
Working procedure of the present invention and principle are:
Fluid is carried by the inner chamber of pipeline, and under normal circumstances, inner-walls of duct is seamless, and liquid can not leak into the interlayer of sealing, and sensor also can't detect carried fluid, can judge pipeline ne-leakage; There is gap and work as inner-walls of duct, while there is seepage, the liquid of seepage can be concentrated in the interlayer that is deposited in sealing, and detected by the sensor in interlayer, the signal of sensor output pipeline seepage, is converted to IP data by GPRS wireless data transmission unit by this signal, sends to remote control center by GPRS communication mode, remote control center can detect this pipe joint road generation seepage at this sensor place, realizes reliably long-range leak detection and the location of carrying liquid.
Compared with prior art, the invention has the beneficial effects as follows:
One, after seepage occurs, the fluid of seepage, by concentrating in the interlayer of pipeline, is detected in time by sensor, is not subject to the impact of other extraneous factors such as ambient noise.Its detection sensitivity is high, and result accurately, reliably; And can directly orient the position of revealing pipeline.
Two, without manually detecting one by one, by wireless transmission method, testing signal is directly transferred to remote control center on the way, artificial a large amount of minimizing of required input, labor cost is low, and can find more timely seepage, avoids waste and environmental pollution; And on pipeline, only need to install a kind of sensor, than multiple sensors and complicated computational analysis processing hardware and software are installed, its system less investment, detects analysis result more accurately and reliably.
The bottom of the interlayer of above-mentioned sealing is provided with the recessed groove that leaks hunting, and installation of sensors is leaking hunting in groove.
The pipeline of this structure is applicable to the situation of the great fluid in air of delivery ratio, and in the time occurring to reveal, the fluid of leakage can concentrate on rapidly and leak hunting in groove, makes sensor can detect reliably more in time the generation of leakage.
Above-mentioned sensor is two, is arranged on respectively the different heights place of the groove that leaks hunting.
In the time carrying specific gravity to be greater than air, the time difference of leak fluid can be detected by two sensors, can calculate the speed (order of severity of leakage) of leakage.
Brief description of the drawings
Fig. 1 is the sectional structure schematic diagram of the embodiment of the present invention one.
Embodiment
Embodiment one
Fig. 1 illustrates, a kind of embodiment of the present invention is, a kind of conveyance conduit that can remote monitoring seepage, comprise interconnective more piece pipeline, it is characterized in that: the tube wall in every pipe joint road of described more piece pipeline is the interlayer 1 of sealing, in the interlayer 1 of sealing, the sensor 3 that can detect the fluid of carrying is installed, sensor 3 is electrically connected with the GPRS wireless data transmission unit 4 in interlayer 1.
The bottom of the interlayer 1 of the sealing of the present embodiment is provided with the recessed groove 2 that leaks hunting, and sensor 3 is arranged on and leaks hunting in groove 2.
This routine sensor 3 is two, is arranged on respectively the different heights place of the groove 2 that leaks hunting.
Embodiment two
The composition of this example and embodiment one are basic identical, unique different only: GPRS wireless data transmission unit 4 is installed on interlayer 1 outer wall.This mounting point makes the power of data transmission lower, transmits more high efficient and reliable, but need on the outer wall of interlayer 1, bore a hole, so that and being electrically connected between sensor, and after connecting, perforation is carried out to encapsulation process.
The GPRS wireless data transmission unit 4 that the present invention adopts is prior art, can be that the various signals that sensor can be exported be converted to IP data, and the wireless terminal device transmitting by GPRS communication.
