[0002] A gas pipeline refers to a pipeline that transports natural gas from the extraction site or treatment plant to the urban gas distribution center or industrial enterprise users, also known as a gas transmission pipeline. Using a natural gas pipeline to transport natural gas, due to reasons such as aging of gas pipeline equipment, geography and climate, and human damage, gas pipeline leakage accidents often occur.

[0004] Although the above solution can facilitate the staff to carry out detection, the detection device in the above patent is not convenient to adjust the detection device according to the lengths of different pipeline joints. Most detection devices have a fixed working length, and when encountering a longer interface pipeline, it is necessary to move the detection device for multiple detections. Therefore, we provide a gas pipeline interface leakage detection device to solve the above problems. Content of the Utility Model

[0009] Two second detection plates are slidably connected inside each of the two first detection plates. A plurality of detection blocks are fixed on one side of the two first detection plates and the four second detection plates. Two moving grooves are formed on one side of each of the two first detection plates.
