AI Technical Summary

Technical Problem

When a fire starts at the bottom of the electrical cabinet's internal cavity, the existing fire extinguishing structure makes it difficult to deliver dry powder and carbon dioxide evenly, resulting in poor fire extinguishing effect.

Method used

Temperature and smoke sensors are used to monitor the fire situation in real time. A PLC controller controls the operation of the delivery pump and stepper motor. The dry powder is delivered evenly through a U-shaped slide frame and gear meshing mechanism. Combined with a geared motor, the hose is prevented from getting tangled.

Benefits of technology

It achieves uniform delivery of dry powder within the power cabinet, improves fire extinguishing effectiveness, avoids hose tangling, and enhances the fire safety of the power cabinet.
