Description

Technical Field

[0001] The utility model belongs to the field of pipeline leakage detection, in particular to a natural gas transmission pipeline leakage detection device. Background Art

[0002] Gas transmission channels play a vital role in modern production and daily life, and they have a vital energy supply responsibility. Gas leakage may lead to serious accidents and environmental damage, which will seriously affect people's well-being, economic strength and the natural environment. Gas leakage quickly spreads into the air, and the accumulation layer of flammable and explosive gases may cause explosion accidents under ignition or high temperature stimulation. This disaster may cause a large number of casualties and property losses. Gas leakage may carry toxic substances, and life safety is seriously endangered by toxic gases. Therefore, it is necessary to conduct regular inspections of natural gas pipelines.

[0003] When inspecting, the existing natural gas pipeline leakage detection device requires a person to hold the detector in one hand to inspect the surface of the transmission pipe. Since the gas transmission pipe is installed against the wall and the height of the natural gas transmission pipe is different, it is easy for the detector to fail to detect in place. The person needs to stand on a stool to inspect the higher pipeline, which is inconvenient and reduces the detection effect of the device. At the same time, the existing detection device absorbs the gas for detection, and after the detection, it is unable to clean up some of the natural gas remaining inside the detection device in time. Directly emitting it is easy to cause some damage to the human body, and the gas remaining inside the detection box is easy to cause inaccurate detection next time, reducing the use of the device.
