By adopting the leakage detection system disclosed by the utility model, leakage sources of pipelines inside and at the bottom can be rapidly found, wherein the pipelines are laminated or staggered, and thus comprehensive review and maintenance on the pipelines can be realized.
Description
Technical field
The utility model belongs to the detection technique field, relates to a kind of in staggered, the range upon range of complex environment of the multiple pipeline of the small space system of detection seepage down.
Background technology
Leak detection is the technical barrier that water supply, heating system must solve always, otherwise causes booster easily, even bigger disaster.Traditional leak detection method is the manual regular inspection, and this certainly will increase hand labor intensity, adds the uncertainty that the workman judges in the checking process, often occurs the situation of omission easily.Along with Development of Infrared Technology, people introduce infrared detection technology in the lysimetric test process of thermal engineering, and this work is regularly to take infrared photograph to heating pipeline, the quality of pipeline whether occurs judging unusually from photo.This method obtains extraordinary effect, and is widely used in the various therrmodynamic systems.At present, cover higher and higher in building industry industry building, various pipelines are more and more closeer, and it is range upon range of and staggered to occur pipeline inevitably; Automobile or other mechanical industry people to the inner space require increasingly highly, under the prerequisite that total length can not enlarge, the space of depositing engine and various circuits is more and more littler, it is range upon range of, staggered to occur various pipelines like this.Because space narrow and small, the workman cannot get into inside and bottom in this case, and conventional artificial inspection seepage method cannot realize; At this moment leak detection method based on infrared photograph also is difficult to realize, can not photograph the range upon range of inside or the photo of bottom line because it can only take the photo of the exposed part outside of pipeline.
The utility model content
The purpose of the utility model provides a kind of seepage detection system based on infrared image processing, to solve the staggered and range upon range of inside of multiple pipeline in the small space or the leak detection problem of bottom line.
Comprising of the utility model based on the infrared image processing seepage detection system:
Thermal infrared imager utilizes the infrared energy distribution pattern of infrared eye reception measured target wherein to be reflected on its light activated element, and converts infrared energy to electric signal by infrared eye;
Display receives the electric signal that the infrared eye conversion forms, and through processing and amplifying, conversion, shows Infrared Thermogram;
Flexible pipe, outer field wrapped with insulation transmission cable is realized being electrically connected of thermal infrared imager and display through self defined interface.
It is further, said that pipeline is carried out leak detection is through the infrared ability of contactless detection.
Further, said flexible pipe is collapsible.
The utility model based on the infrared image processing seepage detection system; Be connected with display miniature thermal infrared imager with flexible pipe; Directly between the slit of pipeline, insert miniature thermal infrared imager when needing to detect inside or bottom line; In the process that detects, move flexible pipe and drive moving of miniature thermal infrared imager; In-line portion or bottom utilize the infrared eye in the thermal infrared imager through the noncontact mode pipeline to be detected, and generate heat picture through longer Distance Transmission and at display again, and the image on the display is watched in manual work; Can accurately judge free from flaw is arranged on the pipeline and accurately locate breakthrough according to the variation of image; Can find the range upon range of or staggered inside and the leak source of bottom line fast, thereby realize the comprehensive inspection and the maintenance of pipeline, solve traditional manual method and infrared detection technology and can only find outside leak source; Can not find the problem of the breakthrough of range upon range of with staggered inside or bottom line rapidly, have great practical value in the preventive maintenance field of whole therrmodynamic system.
Description of drawings
Fig. 1 is the structural representation of detection system.
Embodiment
In therrmodynamic system; Various pipelines all have certain temperature, and they can both emission of thermal radiation, but when there is breakthrough certain; The heat radiation value at this place can obviously strengthen; Infrared thermal imaging technique is exactly to utilize this principle to become the most effective predictive maintenance (PM) technology that industry is generally acknowledged, it can be before fault takes place fast, accurately, orientation problem safely, and device breaks down before, search and keep in repair apparatus; Reduce the generation of making shut down time, production loss, power failure, fire or bust, significantly practice thrift cost.
The utility model also is to utilize this principle, the fast detecting breakthrough.Be illustrated in figure 1 as the structural drawing of seepage detection system, this system comprises:
Thermal infrared imager, the infrared energy distribution pattern that utilization infrared eye is wherein accepted measured target is reflected on its light activated element, and converts infrared energy to electric signal by detector;
Display is accepted the electric signal that the detector conversion forms, and through processing and amplifying, conversion, shows Infrared Thermogram by monitor;
Flexible pipe, skin are insulating material, and the inside is a transmission cable, realize being electrically connected of thermal infrared imager and display through self defined interface.Flexible pipe is folding, when pipeline is carried out leak detection, can bend to tested position, through the infrared ability of contactless detection, by detector convert infrared energy to electric signal after the cable transmission in the flexible pipe to display.
It is through the infrared ability of contactless detection that pipeline is carried out leak detection.
When pipeline is carried out leak detection, can bend to tested position, through the infrared ability of contactless detection, by detector convert infrared energy to electric signal after the cable transmission in the flexible pipe to display.The length of above-mentioned flexible pipe can prolong as required; Also collapsible; This system is applicable to that the pipeline in all size space detects, and therefore is fit to very much be applied to the leakage inspection of automotive front pipeline, the caliduct lysimetric test of Thermal Corp, the accurate location of water heater conduit's seepage of hotel centralizedly supply hot water etc.Detecting the direct hand held thermal infrared imager i3 that is similar to the production of FLIR company that uses for exposed pipeline externally can realize.
For range upon range of with the staggered inside or the leak detection of bottom line,, at first be deep into pipeline inside or bottom to be detected to the miniature thermal infrared imager that is connected on the flexible pipe through the slit between the pipeline because manual work cannot get into pipeline inside or bottom; In the process that detects, move flexible pipe and drive moving of miniature thermal infrared imager; The infrared energy distribution pattern that in-line portion or bottom utilize the infrared eye in the thermal infrared imager to accept measured target through the noncontact mode is reflected on its light activated element, thereby forms infrared energy; Infrared eye in the miniature thermal infrared imager converts the infrared energy that detects to electric signal, and through flexible pipe electric signal is transferred to display, through processing and amplifying, conversion, shows Infrared Thermogram by monitor; Judge the quality of pipeline, the accurate location of realizing breakthrough through showing the heat picture that generates on the display; People can judge the quality of pipeline through watching the heat picture that on the video display of the flexible pipe other end, generates, thus the accurate location of realizing breakthrough.
