AI Technical Summary

Technical Problem

Existing fire extinguishing devices for charging stations suffer from problems such as delayed fire detection, low fire extinguishing accuracy, high cost, difficult maintenance, and poor reliability. They are particularly difficult to extinguish quickly and effectively when lithium batteries catch fire.

Method used

A thermal imager is used to monitor the temperature of the charging area in real time. The control module divides the area into zones and adjusts the outlet angle of the water cannon module to accurately spray water for fire extinguishing. Combined with flow and water pressure sensors, the water spray point is optimized. An emergency switch is set to cut off the power, and the water cannon module is used for rapid cooling and fire extinguishing.

Benefits of technology

It enables early fire identification and precise fire suppression, reduces costs, simplifies pipeline layout, improves reliability and ease of maintenance, adapts to rapid cooling during lithium battery thermal failure, and reduces loss of life and property.

Abstract

The application provides a charging station intelligent fire extinguishing device and method. The device comprises a control module, a thermal imager arranged above a charging area and a water cannon module, the thermal imager being connected with the control module; the thermal imager detects the temperature condition of the charging area in real time, forms a thermal image and sends the thermal image to the control module; the control module partitions the thermal image according to charging positions, and the control module stores the water outlet spray angle corresponding to each charging position or a water outlet spray angle calculation method; the control module locates the charging position with excessively high temperature according to the thermal image sent by the thermal imager, adjusts the water outlet angle of the water cannon module to the water outlet spray angle corresponding to the charging position, and controls the water cannon module to spray water to the charging position. The charging station intelligent fire extinguishing device improves the angle accuracy of water spraying, has high precision and fast response speed, and can aim at the fire point for fire extinguishing or temperature reduction in a very short time.
