Why hasn t the water in the copper jar of the Forbidden City been frozen for hundreds of years?

Because the water in the copper tank of the Forbidden City is used to extinguish fires, in winter there will be thermal insulation measures, and water will be added to it every day to prevent them from freezing and freezing.

The water in the jar will be frozen, but the eunuch who manages the jar will use fire to melt it when the jar is frozen.

Because of the interference of human factors, the fire can be burned under the copper tank filled with water, and there are special people to put a quilt on the copper cylinder cover to keep warm in winter, of course, it will not be frozen.

Why does the water in some tanks in the Forbidden City not freeze for 600 years?

There are about 300 water tanks in the Forbidden City, and the water storage capacity of these tanks is also very strong, each tank can hold about 3,000 liters of water.

The reason why the water tank of the Forbidden City has not frozen for 600 yearsMainly because there are depressions in the stone base of these tanks. When needed, one can add matches to these recesses.

We all know that the construction of the Forbidden City began during the Ming Dynasty, when Zhu Di shifted the political center in order to gather power. The construction of the Forbidden City was very elaborate, and we all know that in ancient times fire was a very serious problem. Because in ancient times, most of the houses were made of wood, and houses with this structure were particularly vulnerable to fire.

At first, people may not notice it, but after a while the wood dries out, these houses are particularly susceptible to fire. Especially in the northern winters, when the winters are very dry, fires are more frequent. The Forbidden City, as a national capital, cannot have large-scale fires, the first is because it is too large, and the second is because it is related to royal glory.

At that time, the court craftsmen installed about 308 water tanks in the palace, and the water in these tanks was designed to prevent fires. Outside the most important basilica there are also four large water tanks, each said to hold 3 tons of water. These four water tanks are known as the Four King Kongs.

We all know that the winter in the capital is very cold, and the water is easy to freeze in such a cold day.

So the craftsmen at that time came up with a very clever approachThey dug holes in the stone in advance when they were making the base for the tank. And this hole is very good at preventing the water from freezingIn the event of a fire, it will not be left without water. Because whenever the water freezes, they will burn a fire underneath it, so that there will be no ice.

To sum up, as the most glorious building in ancient times, the Forbidden City is very ingenious in its design, because it condenses the painstaking efforts of ancient Chinese craftsmen.

Because the water is used to fight fires, there are warm measures next to the water tank, and the person in charge of the palace will also order someone to light a fire under the water tank to ensure that there is no freezing.

The water tank of the Forbidden City is made of fireproof materials, the water tank is used to prevent the use of long, and the water can be put in a special lot, so it is surrounded by warm measures in winter, and it is necessary to make a fire under the water tank.

The large water tank in the Forbidden City, they wrapped it with gold leaf on the outside, but it was a large copper tank on the inside, and when it was cold, the eunuchs would heat it with charcoal at the bottom of the tank to keep the water tank from freezing.

More than 300 water tanks in the Forbidden City have "freezing measures", which are roughly divided into three methods:

1. Charcoal fires can be placed on the top and bottom of the water tank to ensure that the water does not freeze

The more than 300 water tanks in the Forbidden City are equipped with specially built cylinder heads, which are not simply a lid similar to a pot lid, but are specially made to place charcoal in the lid. And the water tank is not placed directly on the ground, it is overhead at the point of the water tank. People who have been to the Forbidden City will find that there is a stone underneath these tanks.

In fact, it is not a simple solid stone, in fact, it can be stuffed into a charcoal fire, that is, it is used to keep water warm. When the weather is very cold, a special eunuch on duty will be on duty every night to put the charcoal burned in advance into the stone at the head and bottom of the tank, so as to prevent the water tank from freezing.

2. Wrap the water tank with a quilt

That's right, more than 300 water tanks in the Forbidden City have their own quilts, and when the weather is very cold, there is no guarantee that the water will not freeze by relying on charcoal fire alone. After all, the charcoal fire will not burn 24 hours a day, and the quilt at this time mainly plays the role of heat preservation.

After using a charcoal fire to raise the temperature of the water, the quilt is surrounded around the water tank, so that it is difficult for the heat in the tank to dissipate and maintain the temperature of the water tank. The reason for this is very simple, in the summer, there are many merchants selling popsicles, bringing loose popsicles to sell everywhere, and around the boxes where the popsicles are placed are wrapped in quilts, just to let the cold air of the popsicles leak out.

In the same way, wrapping the quilt around the water tank can also place the temperature inside the water tank to be absorbed by the cold air outside.

3. There is a special person on duty to stir the water in the water tank regularly, and it is difficult for the living water to freeze

In ancient times, what was most indispensable was manpower, not to mention the center of centralized power in the world. The palace buildings are mostly wooden structures, which can easily catch fire, so the role of these water tanks is extremely important. Then it is not difficult to understand that there are special people to manage these tanks.

When the temperature is very cold, but relying on passive charcoal fire and quilt is not 100% guaranteed that the water will not freeze, so there are special personnel to "stir the water", they will check the degree of freezing of the water tank every once in a while, if there are signs of freezing, the water will be stirred, the stagnant water will become living water, so that the water will not freeze at all.

Generally speaking, these tanks are not only a device used to extinguish fires, but also a kind of "special guard" to ensure the safety of the palace, and their importance is related to the safety of the royal family, so it is understandable that such extravagant and sophisticated means are used to ensure that the tanks do not freeze.

The Forbidden City is a wooden structure of the building complex, the requirements for fire prevention are very high, the water of more than 300 fire tanks in the Forbidden City is not not freezing, but can not freeze, there is space reserved under the tank, and in winter, firewood will be added to the bottom to heat to prevent the water from freezing. Just in case.

Because there are insulation devices on the outside of the tank, and these tanks are placed on top of the square grooves, charcoal fire will be added to the bottom when the weather is particularly cold to ensure that the tank does not freeze.

The eunuchs would heat the tank to keep it warm, wrap it around the tank with cotton material, cover the lid of the tank, and if the weather is particularly cold and the temperature is very low, they will put the tank in the stone circle and add fire to it so that it does not freeze.

The winter in Beijing is very cold, the water surface will freeze, the ice surface is very thick, people can play on it, it stands to reason that the water tank of the Forbidden City should also be thick with ice, however, the water tank of the Forbidden City is not frozen,Because in the winter they will wear thick "clothes" to keep warm, the temperature is too low, and some people specially light a fire for them.

Although it sounds simple and simple, but at that time the level of science and technology and awareness, this was already a very effective and fast method, in order to prevent the water tank in the Forbidden City from freezing in winter, the ancients actually came up with this method, I have to say that the ancients were still very smart.

So why do you want to do this, after relevant research experts by consulting the historical records of the palace in the Ming and Qing dynasties, they found that these large water tanks were actually the earliest and most practical fire protection facilities at that time.

Because winter is the most likely season to cause firesIn the previous winter, the water tank must not freeze, in order to prevent the Forbidden City**, causing serious losses.

With the development of science and technology, the Forbidden City is now more complete fire prevention tools, the role of these water tanks is mostly for tourists to visit, some people who go to the Forbidden City to play, in order to be lucky, will also touch these water tanks, some water tanks are darkened.

But in order to prevent this majestic work of art from happening and to better protect it, the ancient habits continue despite the advanced fire protection system.

In order to extinguish the fire in time when there is a fire, a groove is made under the base of the water tank to place the charcoal fire, so that the water in the tank will not freeze. In addition, special personnel will be arranged to inspect every day to ensure that the water in the tank does not freeze. If it freezes, someone will immediately arrange for someone to chisel the ice apart.

Because when it's cold, the bottom of the water tank will burn.

Because the water in the tank in the Forbidden City is not ordinary water, it has never froze for 600 years.

Because underneath each cylinder there is something like a brazier, which can be heated.

Because the water in this pool is not ordinary water, it does not freeze even when it snows.

This should be related to the structure of the cylinder. Some tanks are made of materials that are warm in winter and cool in summer, so the water in the tank will not freeze for 600 years.

The water in the Forbidden City tank never froze, because every winter it was covered with thick clothes, and some people lit a fire underneath.

Because in winter, some measures are taken to prevent the water from freezing.

There must be some insulation measures, and it will be heated when it is about to freeze.

It's not that it doesn't freeze, and the tank that used to hold water will be insulated, and a fire will be lit under the tank to keep the water from freezing.

Why does the water in some tanks in the Forbidden City not freeze for 600 years?
