The use of fire has profoundly affected the evolution of human beings, but while lighting up human civilization, fire has also brought painful harm to human beings. According to the statistical data on the comprehensive situation of fires in different regions of the country released by the Fire Department of the Ministry of Public Security in recent years, the number of casualties and economic losses caused by fires in my country have an increasing trend year by year. A large part of the reason is that the use of fire is a unique skill of human beings, and at the same time, the places of human production and living are inseparable from buildings. With the rapid development of the economy, more and more high-rise buildings appear in the city, and the high-rise buildings are covered with a large number of gas pipelines and electrical lines. Casualties also intensified.

As an important water source that firefighters rely on when a fire breaks out, the fire pipe network is a must for all high-rise buildings, especially at heights that cannot be reached by fire water trucks. The importance of the fire pipe network is self-evident. However, since the stored water in the fire-fighting pipeline is easily affected by temperature, pipe bursts may occur in low-temperature weather, and the cold and dry winter is the season of high fires, so the antifreeze treatment of fire-fighting pipelines is particularly important.

Nowadays, the common antifreeze treatment measures for fire-fighting pipelines mainly include: wrapping fire-fighting pipelines with thermal insulation materials, forming long flowing water or circulating water in partial branch pipes of fire-fighting pipelines, and adding electric heating cables to fire-fighting pipelines, but these methods or effects are not obvious or require Generate extra power consumption, so it is urgent to find a high-efficiency and energy-saving fire protection pipe antifreeze device to protect the fire water source of high-rise buildings. Since each high-rise building usually has a large area of glass curtain wall, using transparent solar cells to replace ordinary building decorative glass, and then using the energy generated by distributed solar power to keep fire pipes warm and antifreeze will have a wide range of application prospects.
