The invention relates to a natural gas pipeline leakage detection system based on an unmanned aerial vehicle. The system is provided with a combustible gas detection mechanism, wherein the combustiblegas detection mechanism comprises a combustible gas detector, a gas entraining system, a flow dividing cover, the unmanned aerial vehicle and a flight control system, the combustible gas detector hermetically communicates with the gas entraining system, and the flow dividing cover is slidably connected to the gas entraining system; a combustible gas pipeline leakage detection system is suspendedand fixed below a flying platform of the unmanned aerial vehicle and used for collecting and detecting gas data in a natural gas pipeline area, and the flight control system is used for controlling the unmanned aerial vehicle and receiving detection data transmitted by the combustible gas pipeline leakage detection system; and through the scheme, the technology of quickly and accurately detectingleakage of a natural gas pipeline is realized, meanwhile, the defect that when the unmanned aerial vehicle is used for gas detection, when the unmanned aerial vehicle hovers, downward airflow can be generated by propellers of the unmanned aerial vehicle to blow away air near a detection area, and therefore the combustible gas pipeline leakage detection system cannot accurately detect the pipelineleakage condition is overcome.
Description
technical field [0001] The invention relates to the technical field of natural gas detection, in particular to the field of natural gas pipeline leakage detection equipment, in particular, a natural gas pipeline leakage detection system based on an unmanned aerial vehicle. Background technique [0002] For oil pipeline inspection projects, especially long-distance oil and gas pipelines (within 400km in length) and regional oil and gas field fault block systems (with an area of about 100km2), these projects often require "short, flat and fast" and short measurement cycles , The task is heavy, the quality is high, the terrain and landform in the region are complex and changeable, and it often passes through uninhabited areas such as deserts, Gobi, forests, mountains, etc. Sometimes surveyors and instruments cannot reach them. [0003] Chinese patent CN201610122739.9 discloses a UAV-based natural gas pipeline leakage detection system. The solution uses a small natural gas las...
