AI Technical Summary

Technical Problem

The existing fire-fighting water systems in ancient buildings are prone to freezing in winter, making it impossible to draw water in time in the event of a fire, and there is a lack of effective antifreeze measures.

Method used

An antifreeze circulation device was designed, comprising a circulation tank, an inlet pipe, an outlet pump, a temperature sensor, a heater, a controller, and an isolation component. The temperature sensor monitors the water temperature, the controller controls the heater to heat the water to ensure that the water temperature is not lower than the set value, and the isolation component ensures that the cold water is in full contact with the heater to prevent freezing.

Benefits of technology

It effectively prevents fire water from freezing in low-temperature environments, ensures the normal operation of the fire water system in cold weather, protects the fire safety of ancient buildings, and simplifies the inspection and maintenance process of the device.
