This invention relates to the technical field of pipeline leak detection devices, specifically a helium-nitrogen mixed gas pipeline leak detection device. It mainly includes a main body, with a flexible hose connected to the air inlet of the main body, and a connecting pipe connected to the other end of the hose. It also includes: a filter mechanism disposed inside the connecting pipe; an adjustment mechanism disposed below the connecting pipe; and a cleaning mechanism disposed inside the connecting pipe. When detecting a pipeline leak by bringing the suction tube close to the outer wall of the pipeline, the suction tube draws in the gas from the outer wall of the pipeline. The gas enters the main body for detection through the connecting pipe, connecting sleeve, connecting pipe, and flexible hose. As the gas passes through the connecting pipe, it is filtered by the filter cartridge and filter frame. These dust particles will not enter the mass spectrometry analysis chamber of the main body and will not interfere with the detection of helium ions. Even minor leaks in the pipeline can be accurately identified, thereby improving the accuracy of the detection.
