AI Technical Summary
Technical Problem
In extremely cold weather, existing pit-type energy storage systems are prone to fire-fighting pipes freezing and becoming blocked, making it impossible to extinguish fires in a timely manner.
Method used
Firefighting modules and heat conduction modules are installed in the fire pit. The hot air generated by the energy storage module is heated by the fan through the main heat pipe to heat the fire pipe and fire water, preventing freezing.
Benefits of technology
It achieves the reliability and timely response capability of the fire protection system in extremely cold environments, saves energy, prevents fire water from freezing, and ensures the normal operation of the fire protection system.

Abstract
This invention discloses a pit-type energy storage system and its antifreeze control method, relating to the field of energy storage system structure technology. By setting up a fire-fighting pit and an energy storage pit adjacent to each other, and connecting a fan to one end of a main heat pipe sleeved on the outer wall of the fire-fighting pipe, with the other end extending into the energy storage pit, the fan can draw the hot air generated by the energy storage module during operation into the main heat pipe. This allows the hot air to directly heat the fire-fighting pipe inside as it flows through the main heat pipe, preventing the water in the fire-fighting pipe from freezing and causing blockage in extremely cold weather. At the same time, after flowing through the main heat pipe, the hot air continues to exchange heat with the fire-fighting water in the fire-fighting pit, raising the overall temperature of the fire-fighting water. Thus, without the need for an additional heat source, the waste heat of the energy storage system itself achieves comprehensive antifreeze protection for the fire-fighting system, saving energy and ensuring the reliability and timely response capability of the fire-fighting system in extremely cold environments.
