Description

Technical Field

[0001] The invention relates to the field of methane detection, and in particular to an installation device for a handheld positioning methane detector. Background Art

[0002] A coal mine refers to an area rich in coal resources and is often also referred to as a coal production plant using underground or open-pit mining methods. When coal seams are far from the surface, coal is typically mined by tunneling underground, a process known as an underground coal mine. When coal seams are close to the surface, coal is typically mined by directly removing the surface soil, a process known as an open-pit coal mine. During coal mining, methane gas is generated because the coal remains stored underground. Measuring methane concentrations in the mine is crucial. A methane detector is an intrinsically safe device that can continuously monitor methane concentrations. It is suitable for explosion protection, methane leak rescue, and locations such as underground pipelines and mines, effectively protecting workers and equipment from damage. Furthermore, with the development of natural gas, cities are gradually switching from coal gas to natural gas due to its high calorific value, high utilization rate, and environmental friendliness. Regular leak inspections of natural gas pipelines are essential for daily gas supply to ensure proper sealing and enhance safety.

[0003] When the existing methane detector needs to continuously detect the concentration of methane during use, it is difficult to place it due to the lack of a necessary installation base. Summary of the Invention
