AI Technical Summary

Technical Problem

The existing coal mining machine electrical control box lacks effective water immersion monitoring methods, making it impossible to detect leakage problems in time, resulting in damage to electrical components and equipment downtime, affecting production efficiency and maintenance costs.

Method used

The system employs a combination of a water-immersion rope, a water-immersion transmitter, and a PLC controller. The water-immersion rope senses water droplets, the water-immersion transmitter converts and amplifies the signal, and the PLC controller stops the equipment and triggers an alarm, thus achieving real-time monitoring and protection.

Benefits of technology

It enables real-time monitoring of water immersion in the electrical control box, protecting electrical components, reducing maintenance costs, ensuring normal equipment operation, and improving production efficiency and reliability.
