Description
Technical field
The utility model relates to the vehicle-mounted gas leak detector, is used for gas industry to whether having gas leakage to detect at the labour pipeline.
Background technique
Gas pipeline is as one of requisite Infrastructure in city, and along with the acceleration arrival of urbanization process, China's most city gas ductwork has had very big development, and very big contribution has been made in the raising of environmental protection and living standards of the people in recent years.Yet gas ductwork has also brought many potential safety hazards in fast development.Because gas has characteristics such as inflammable, explosive; If there are quality problems in gas pipeline in manufacturing, work progress; What is more in use receives the influence of surrounding environment or miscarriage meeting to make pipeline generation corrosion, bore a hole, break; Make gas leakage, cause environmental pollution and potential safety hazard.Therefore, how to find piping corrosion, breakage, gas leakage point fast and accurately and take corresponding countermeasure to repair, in time prevent and control the generation security incident, be the target that gas enterprise is pursued always.
For many years; Many cities are the pump suction type leak detectors to the gas ductwork used detecting instrument that whether leaks gas mostly; Usually the pump suction type leak detector has vehicle carried type and hand-held, and whether the principle of this quasi-instrument is the gas around detecting to be sucked in the instrument carry out filter analysis, differentiate and leak gas.Though the pump suction type leak detector can accurately detect pipe network leak source position, also have some shortcomings in using, mainly be:
1. the pump suction type leak detector can only closely detect pipeline, then is difficult to detect the gas leakage point more than 1 meter the time if depart from conduit axis.Therefore, when detecting with the pump suction type leak detector, must mark the axial location and the direction of pipeline on the ground for underground utility.
2. when vehicle-mounted pump suction type leak detector detected the pipeline under the road, its road location should be on the road surface directly over the pipeline, is unfavorable for road traffic.
3. the hand-held leak detector needs personnel's walking to detect along pipeline, and labor intensity is big, and efficient is low.
For the gas pipeline of river crossing, enclosure wall etc. then difficulty or ease detect.
Summary of the invention
The purpose of the utility model is in order to overcome problem and the shortcoming that above-mentioned detection technique exists; A kind of vehicle-mounted gas leak detector is provided, and the function that this leak detector is mainly realized is: 1. employing is distant detects apart from scanning, increases disposable area of detection; Reduce detected intensity, improve detection rates; 2. can detect gas pipelines such as crossing over river course, enclosure wall, high building external riser at a distance; 3. not limited by pipeline position and track when detecting on the highway; 4. this leak detector can take off in the place of driving inconvenience and hand distant distance detection.
The technological scheme of the utility model is:
The vehicle-mounted gas leak detector; Comprise transceiver, controller, datawire, transceiver block, half-round clamping ring, The Cloud Terrace, automobile, it is characterized in that: described The Cloud Terrace is fixed on the outer top of automobile, and transceiver block is installed in the The Cloud Terrace upper end; Transceiver is installed in the transceiver block and by half-round clamping ring and fixes; Controller is placed on to be convenient to the inspector and to operate and observe in the car,, datawire connects transceiver and controller.
Described transceiver has emission laser and the function that receives reflecting light, simultaneously, the light wave of reflected back is converted to electrical signal and is transferred to controller by datawire.
The emission and the reception of described controller major control transceiver simultaneously, are analyzed the electrical signal of transmission, having judged whether gas leakage, and have gas concentration to show and warning function.
Described The Cloud Terrace can be at the same time or separately in horizontal plane with vertical plane in rotation automatically, and drive that transceiver is multi-faceted to be scanned, to enlarge detection range.
Described transceiver is also launched red cursor when transmitting and receiving light wave, so that can confirm the position of gas leakage point fast and accurately.
During work, open transceiver, start The Cloud Terrace and be rotated the scanning detection.After passing through gas pipeline or facility superjacent air space, shine the other end target (as: wall, road, tree or pillar etc.) by transceiver emitted laser bundle; Segment beam will be back to transceiver by target; And convert electrical signal to by transceiver, be transferred to controller through datawire.In transceiver emitted laser bundle kind, there is a kind of light beam of special wavelength to be prone to be absorbed by methane (main component of natural gas), the light beam of reflected back is compared analysis, just can measure the concentration that contains methane in the space that detects.When the survey methane concentration when demarcating concentration, controller just can be reported to the police.The red light cursor position of launching at this moment, the orientation a little of just can confirming to leak gas according to transceiver.
The mode gas pipeline (ground or underground gas pipeline) local to highway, street and vehicle drivable that the utility model is used rotation sweep carries out the leak source detection; Improved detection rates greatly; Reduced labor intensity; Can measure the pipe network gas leak phenomenon quickly and accurately, the safe operation of protecting gas ductwork is had bigger effect.
