The number of volunteers assigned to the rescue team in the city is not large. After Chen Xin had breakfast, a team of about 50 volunteers led by the staff in the city to the rescue station to help.
After these volunteers arrived, they were immediately assigned to work. They assisted in maintaining order in the reception area, helped patients see a doctor, and went to the ward to help take care of critically ill patients... I have to say that with these volunteers, the work of the rescue team has indeed changed It's a lot easier, and medical staff can better focus on how to treat patients.
The team leader also sent five volunteers to Chen Xin as he promised to assist him in transforming the spare tent.
"Hello, we are volunteers here to help. What do we need to do?" The five volunteers came to Chen Xin and looked at Chen Xin who was wearing his power armor today, with envy in their eyes, and A trace of fear.
Power armor, something that can only be seen in previous sci-fi works, is naturally enviable. The five volunteers who came here are all young people. They are even more greedy for power armor, which is not usually seen. thing.
However, the mechanical arm on Chen Xin's back is quite hideous, and coupled with the unknown psychology of power armor, it is not surprising that he is a little afraid of it.
Chen Xin looked at them, but smiled and said to them: "You can help to set up this tent first. I need to make some cold-proof renovations for these tents."
"Okay, how do I do this?" Several volunteers came to Chen Xin and asked them what they should do without refusing.
"These white bags are the tents. I will choose the location. You only need to spread the tent, and then use the air pump over there to inflate the tent." Chen Xin pointed and placed it under his feet. Some of the white bags in the company explained to them: "This kind of tent is easy to set up, but after that, you need to install lighting and place hospital beds. Thank you."
"This is what we should do. You help save people. We are just doing some physical work, which is nothing." Several volunteers were very humble and polite.
Chen Xin didn't say much when he saw it. He instructed the five people to unfold the tent, and after the selected place was laid, it was inflated with the air pump prepared in advance.
This kind of tent relies on air column support. It only needs to be filled with air to support the entire tent. It is a very convenient temporary device to erect. With the help of five volunteers, the first tent only costs It took ten minutes to be supported.
But this can’t be regarded as a tent. In addition to continuing to inflate to maintain the strength of the air column and maintain the support of the tent, the tent needs to be fixed with ground nails, such as lighting tubes and heating. The heating stove and supporting hospital beds need to be arranged.
Chen Xin asked two volunteers to fix the ground nails, and he and another volunteer installed the lamps to be fixed to the top of the tent. As for the remaining two volunteers, Chen Xin was sent to carry the hospital bed and the heater.
The space inside the tent is not low. If an ordinary person installs a light tube, he may have to set up a stool, but Chen Xin only needs the assistance of a robotic arm.
Seeing Chen Xin using his robotic arm to install the lamp to the reserved position on the top of the tent, the volunteer on the side suddenly asked curiously: "Brother, is your power armor issued by the state? Our country still has this kind of power armor. Good thing? How can I get a set of this? You belong to a special unit, right?"
"You said this? I don't know. If you want to know, you should ask the relevant department." Chen Xin vaguely said, and did not mention that this set of power armor was made by himself.
Although he can understand the volunteer's curiosity and admiration for power armor, there are still some things that don't need to be said to people casually.
When the volunteer heard Chen Xin's words, he thought it was Chen Xin who needed to keep it secret, so he didn't ask any more, but his eyes on the power armor became more envy.
The group was busy for more than half an hour. With the help of five volunteers, this set of spare medical tents was finally set up.
This spare tent has the same specifications as the tent currently being used as an ambulance station, except that it lacks supporting medical equipment and medical staff. All other parts are the same. As long as it is equipped with medical staff and medical equipment, this is it. The second ambulance station.
However, the current medical staff of the rescue team is limited. Even the volunteers who came to support are only able to use the second set of medical tents as a new ward, and there are not enough doctors to open a second rescue station.
The medical tent itself is not bad in terms of cold protection. According to the technical parameters in the manual found by Chen Xin, this tent can adapt to a temperature of -40°C to 65°C, and can perform its due role even in severe cold weather conditions.
Just being able to adapt to the ambient temperature of -40°C is not enough for now, so it must be upgraded in terms of cold protection.
The cold protection of the tent mainly relies on the space left between the inner and outer layers of the tent, and this space is used as an insulation layer to achieve the effect of heat preservation.
It's like double-layer glass is colder than single-layer glass. The efficiency of heat transfer between different media is different. Leave a space between the two layers of cold-proof materials to avoid direct heat transfer to the outer layer, which can play a better Thermal insulation effect.
But the effect of this is also limited. UU Reading www. uukanshu.com Therefore, the medical tents are now equipped with heaters for heating, so that the temperature in the medical tents can be maintained at a relatively low temperature.
In addition, another important thing for tents is the floor mat. Without a floor mat with good heat insulation performance, it is difficult to maintain the temperature inside the tent.
Similarly, if Chen Xin wants to upgrade the thermal insulation effect of the tent, he will mainly focus on these two aspects.
Chen Xin has checked before that the material of this spare medical tent and the material of the medical tent that have been erected are all PVC airtight cloth, mainly through a layer of cold-proof cotton superimposed on it and the interlayer space between the inner and outer cloth To play a role in insulation.
To improve the thermal insulation effect, the first choice is of course to improve the material. Substituting the materials of the tarpaulin and floor mats with better thermal insulation materials can naturally improve the thermal insulation effect of the tent.
Another option is to improve the structure of the tent to block the heat conduction path and reduce the heat dissipation, which can also achieve the effect of heat preservation.
