Background Art

[0002] Among the existing coal mine fire prevention and extinguishing technical methods, the liquid carbon dioxide method can achieve rapid cooling on the basis of inerting. When the liquid carbon dioxide is injected into the fire zone, it will instantly vaporize, expand in volume, flow and diffuse, absorb a large amount of heat, and rapidly reduce the temperature and oxygen concentration in the fire zone. It shows great advantages in the management of mine fire zones. It can be evenly regulated and transported by the equalizing pressure and constant flow device. The connection node between the two needs to increase the stability of the connection between the two through a protective connection mechanism. However, the existing nodes are all connected by flanges and fixed by multiple bolts. The bolts will rust over time and become loose, thereby affecting the stability of the connection between the two, causing leakage, causing unnecessary trouble, and reducing subsequent work efficiency.

A caliper-type protective connection mechanism can be designed to improve practical efficiency by strengthening the stability of the node connection between the two. Utility Model Content
