Chapter 347

The number of volunteers assigned to the rescue team by the city is not large. After Chen Xin had breakfast, a team of about 50 volunteers led by the city's staff came to the rescue station to help.

After these volunteers arrived, they were immediately assigned to work in the reception area to help maintain order, help patients see a doctor, and go to the ward to help take care of the critically ill patients It has to be said that with these volunteers, the work of the rescue team has really become a lot easier, and the medical staff can better focus on how to treat patients.

As he promised, the team leader sent five volunteers to Chen Xin to help him transform the spare tent.

"Hello, we are volunteers here to help. What do we need to do?" Five volunteers came to Chen Xin and looked at Chen Xin, who was wearing his power armor today, with envy and fear in his eyes.

Power armor, which was only seen in science fiction works before, is naturally enviable. In addition, the five volunteers are all young people, so they are even more greedy for power armor. It's a good thing that they can't see at ordinary times.

However, the mechanical arm on Chen Xin's back is quite ferocious, and it's not surprising that he is afraid of the unknown power armor.

Looking at their appearance, Chen Xin just laughed and said to them, "help to set up this set of tents first. I need to do some cold proof renovation for these tents."

"OK, how can I do this?" Several volunteers did not refuse, came to Chen Xin and asked what they should do.

"These white bags are tents. I'll choose the right place. You just need to spread out the tents and inflate them with the air pump over there. Then you can put up the tents." Chen Xin pointed to the white bags under his feet and explained to them, "this kind of tent is easy to set up, but after that, you need to install lighting and put hospital beds. It's hard for you."

"This is what we should do. You help to save people. We just do some physical work. It's nothing." Several volunteers were very modest and polite.

Chen Xin didn't say much. He directed five people to spread out the tent. After the tent had been laid in the selected place, he inflated it with the air pump prepared in advance.

This kind of tent relies on the air column support inside. It only needs to be filled with air, and the whole tent can be supported. It is a kind of convenient temporary equipment. With the help of five volunteers, the first tent only took more than ten minutes to be set up.

However, this can not be regarded as a good tent. In addition to continuing to inflate air to maintain the strength of the air column and the support of the tent, it also needs to use ground nails to fix the tent, such as lighting tubes, heating furnaces and matching hospital beds.

Chen Xin asked two volunteers to fix the ground nails. He and another volunteer installed the light tubes to be fixed on the top of the tent. The remaining two volunteers were sent by Chen Xin to carry the beds and heaters.

The space inside the tent is not low. If ordinary people install lights, they may have to set up a stool, but Chen Xin only needs the help of a mechanical arm.

Looking at Chen Xin installing the light tube to the reserved position on the top of the tent with a mechanical arm, the volunteer on one side suddenly asked curiously, "brother, is your power armor made by the state? Is there such a good thing in our country? How can I get this set? Are you from the special forces? "

"You say this? I don't know. If you want to know, you should ask the relevant departments. " Chen Xin made a vague remark, did not elaborate on anything, and did not mention that this set of power armor was made by himself.

Although he could understand the curiosity and admiration of the volunteer for power armor, there was no need to tell people about some things.

When the volunteer heard Chen Xin's words, he thought it was Chen Xin who needed to keep secret, so he didn't ask any more questions. He just looked at the power armor with more envy.

They were busy for more than half an hour. With the help of five volunteers, all the spare medical tents were set up.

This set of spare tent is the same specification as the one that is now used as the ambulance station, except that the supporting medical equipment and medical staff are missing. The other parts are all the same. As long as the medical staff and medical equipment are provided, this is the second ambulance station.

But at present, the medical staff of the rescue team is limited. Even if the volunteers are included, they are only enough to use the second set of medical tents as a new ward, and there are not enough doctors to open up a second ambulance station.

In fact, the cold proof effect of the medical tent itself is not bad. According to the technical parameters in the manual found by Chen Xin, the tent can adapt to the temperature of - 40 ℃ ~ 65 ℃, even in the severe cold weather conditions.

It's just that it can adapt to the ambient temperature of - 40 ℃, which is not enough for now, so it must be upgraded in terms of cold protection.

The cold proof of the tent mainly depends on the space between the inner and outer layers of the tent, which is used as the heat insulation layer to achieve the effect of heat preservation.It's just like that double-layer glass is more cold proof than single-layer glass. The efficiency of heat conduction between different media is different. Leaving space between two layers of cold proof materials to avoid heat transfer directly to the outer layer can play a better insulation effect.

But the effect is limited, so now the medical tents are equipped with heaters for heating, which can maintain the temperature in the medical tents at a relatively low temperature.

In addition, there is also a very important thing for the tent, which is the mat. Without a good insulation mat to insulate the heat from losing downward, the temperature in the tent is still very difficult to maintain.

Similarly, if Chen Xin wants to upgrade the thermal insulation effect of the tent, it is mainly aimed at these two aspects.

Chen Xin has checked before that the material of the spare medical tent and the erected medical tent is PVC airtight cloth, which is mainly used for heat preservation through a layer of cold proof cotton and the interlayer space between the inner cloth and the outer cloth.

If you want to improve the thermal insulation effect, the first choice is of course to improve the materials. Replacing the tarpaulin and mat materials with materials with better thermal insulation performance can naturally improve the thermal insulation effect of the tent.

Another option is to improve the structure of the tent, block the way of heat conduction, reduce the heat emission, which can also play a thermal insulation effect.
