Description

Technical Field

[0001] This utility model relates to the field of gas detection technology, specifically to an auxiliary device for the detection and repair of gas pipelines in municipal construction using a TDLAS laser gas detector. Background Technology

[0002] Municipal gas pipelines are a critical infrastructure for urban energy supply, and their safe and stable operation is directly related to residents' lives and the normal functioning of the city. Gas leaks can cause serious accidents such as explosions and fires, resulting in huge casualties and property losses. Statistics show that a significant portion of gas-related accidents are caused by gas leaks due to pipeline aging, construction damage, corrosion, and other reasons. Therefore, efficient and accurate detection and timely repair of gas pipelines are important measures to ensure urban safety.

[0003] Traditional detection methods involve workers using handheld detection equipment to eliminate pipeline leaks, which is time-consuming, labor-intensive, and inefficient, failing to detect leaks accurately. Therefore, this paper proposes an auxiliary device for the detection and repair of municipal construction gas pipelines using a TDLAS laser gas detector. Utility Model Content
