Abstract

The invention discloses a device for monitoring the leakage of an underground gas pipeline, which comprises: a gas pipeline monitoring pipe arranged above the pipeline to be monitored; side plates respectively arranged on both sides of the monitoring pipe; a valve arranged at the right end of the monitoring pipe; The gas monitor at the left end of the monitoring pipe; the suction pump arranged at the left end of the gas monitor; the pipelines arranged at both ends of the monitoring tube, which are used to connect the valve, the monitoring tube, the gas monitor and the suction pump into one Gas circuit; it has an information processing module that controls monitors, suction pumps and valves, and the information processing module includes a signal transmitter and a processor. The invention solves the technical problem that the gas pipeline monitoring device in the prior art has low precision, large error and cannot accurately reflect the leakage situation of the pipeline.

Description

technical field [0001] The invention relates to the field of pipeline network monitoring, in particular to a device for monitoring leakage of underground gas pipelines. Background technique [0002] With the continuous deepening of China's reform and opening up and the optimization and adjustment of the energy structure, the proportion of clean, efficient and sustainable use of energy in the structure is getting higher and higher. As one of the clean and efficient energy sources, gas demand is increasing year by year. In order to meet the demand of the urban gas supply market, the urban pipeline construction department has accelerated the pace of pipeline construction. Therefore, the length of the pipeline has increased rapidly and the radiation area of ​​the pipeline network has gradually expanded. With the increase of pipeline length and service life, the frequency of urban buried gas pipeline leakage accidents has increased due to corrosion, external mechanical damage, p...
