AI Technical Summary

Technical Problem

Existing fire extinguishing devices for prefabricated energy storage cabins have long response times in unmanned scenarios, making it difficult to contain the spread of fire in the early stages of a fire. Furthermore, their fire extinguishing accuracy is poor, failing to meet the demand for rapid and precise fire suppression.

Method used

A gas concentration analyzer is used to extract and analyze the gas inside the battery box through a fire detection tube. Combined with a three-way reversing valve to switch between the extinguishing flow channel and the suction flow channel, early fire monitoring and rapid response are achieved, simplifying the piping structure and reducing installation space.

Benefits of technology

It enables early monitoring of fire hazards inside the battery box, simplifies the pipeline structure, reduces complexity, improves response speed and fire suppression accuracy, and meets the high requirements of prefabricated energy storage compartments.

Abstract

The utility model relates to fire extinguishing equipment discloses fire extinguishing device in the energy storage prefabricated cabin, including fire extinguishing agent bottle group, full submergence nozzle, pack level pipeline, air extraction concentration analyzer and three -way reversing valve, the pack level pipeline is installed and inserts into the fire -finding pipe of battery box, the low -leakage high -sealed suction valve is installed to the end of fire -finding pipe, one end of air extraction concentration analyzer is connected with pack level pipeline and draws air through the low -leakage high -sealed suction valve on fire -finding pipe, three -way reversing valve is equipped with fire extinguishing flow channel, suction flow channel and piston rod, fire extinguishing flow channel at least one of fire extinguishing agent bottle group and pack level pipeline, full submergence nozzle is communicated, and suction flow channel is communicated with air extraction concentration analyzer through pack level pipeline. Air extraction concentration analyzer draws the gas in battery box directly through fire -finding pipe and carries out analysis, realizes the early monitoring to the fire hazard in battery box. Three -way reversing valve makes fire extinguishing agent pipeline and suction pipeline be same pipeline, simplifies pipeline arrangement.
