Pipeline safety monitoring device and system for gas pipeline engineering construction

The invention provides a pipeline safety monitoring device and system for gas pipeline engineering construction, and relates to the technical field of safety monitoring devices. The pipeline safety monitoring device for gas pipeline engineering construction comprises a detection device, wherein a threaded rod is fixedly installed at the bottom of the detection device. The invention further provides the pipeline safety monitoring system for gas pipeline engineering construction. The pipeline safety monitoring system for gas pipeline engineering construction comprises a measurement module, wherein the measurement module is used for being electrically connected with a detection probe; and the measurement module is used for detecting the flow condition, air pressure and various indexes needing to be detected in a pipeline through the detection probe. A circular plate is moved towards the two sides, a U-shaped rod moves on a rectangular block, the other end of the U-shaped rod leaves an insertion hole in a rotatin
