AI Technical Summary

Technical Problem

Existing warning lights for coal mines have poor sealing of the lamp plate cavity, are heavy, have low stability, and low safety. They cannot operate safely and reliably in methane and explosive gas environments or humid environments, resulting in short service life and high failure rate.

Method used

The lamp cover plate is bonded to transparent glass and glass pressure plate to form a sealed protective structure. Combined with the design of explosion-proof gland head and countersunk screw hole, the cavity is sealed and explosion-proof. The flame energy is reduced by the explosion-proof joint surface, and the structural stability is enhanced by adhesive and sealing gasket to meet the explosion-proof requirements of mining.

Benefits of technology

It improves the reliability and safety of the lamp panel cavity in the mining environment, extends its service life, prevents explosive gases and dust from entering, reduces the failure rate, and ensures stable operation of the lamp panel in complex environments.
