[0002] Oil, natural gas, and coalbed methane are important energy resources that play a vital role in global economic and industrial development. Safety monitoring is a key component of ensuring production safety, protecting the environment, and preventing accidents during the extraction and utilization of these energy resources. Oil and natural gas are major global energy sources and are widely used in transportation, industrial production, home heating, and electricity generation. As a relatively new natural gas resource, coalbed methane (CBM) mining helps reduce methane emissions from coal mining and provides a new source of energy supply. In summary, safety monitoring of oil, natural gas, and CBM is a multifaceted, multi-layered system that involves technology, regulations, economics, and the environment. Effective safety monitoring can ensure the safe, efficient, and sustainable utilization of these valuable energy resources.

[0003] At present, the detection and early warning devices used in the process of oil, natural gas and coalbed methane extraction can alarm when a leak occurs during use, but the leak will continue after the alarm and cannot be sealed in time, thus causing environmental pollution and loss. Therefore, a oil, natural gas and coalbed methane safety monitoring and early warning device is proposed. Utility Model Content
