Lin Jing noticed that everyone was so excited, so he poured cold water on everyone, "Don't think of the problem so simply. The principle sounds simple, but it is not simple to implement. First of all, the biggest problem is the vegetable cellar.
How to solve the insulation problem of the door? Can multiple layers of quilts block the invasion of cold wind?
The second thing is how to ensure that the temperature of the vegetable cellar can be restored to the appropriate temperature as soon as possible every time I take out vegetables. Throwing an electric heating jacket in is just my initial idea. It is best to have an electric heating device that slowly increases the temperature. It is best to
Can directly pass 220 volt AC power.
I already have an idea in this regard. I can transform our extra used electric blankets. As for the temperature-regulating equipment of the electric blankets, we can even pull it directly to the gate area inside the post, so that we can directly control the vegetable cellar from inside the post.
temperature, which can solve many problems."
When Deputy Squad Leader Qiao heard this, he quickly said: "Platoon leader, you do the technical work, and we will do the rough work. I will leave the transformation of the electric blanket to you, and dig the snow to cover the insulated house in the depression under the post.
Leave it to us, you can see if it works."
Lin Yi nodded immediately, "Okay, then I will modify the electric blanket equipment first, and then adjust the temperature and humidity probe. You can dig out the snow as soon as possible and build an insulated house."
The division of labor was completed, and everyone took action immediately to dig out as much snow as possible while it was still dark.
Lin Yi began to renovate the old electric blankets. There were not many electric blankets in the post. No one could guarantee that there would always be heating in the post. As a unit far away from the regiment headquarters, in many aspects, it was necessary to have
Forward-looking.
The electric blanket is a very important emergency heating equipment in the outpost after the heating is stopped. When the electric blanket is turned on to the maximum, the temperature is about 40 degrees. There is no problem at all in maintaining a person's normal body temperature.
Lin Yi's method of transforming the electric blanket is also very simple, which is to remove as much cotton as possible outside the electric heating wire. The cotton will hinder the heat dissipation to a great extent. For a vegetable cellar, it requires more temperature.
OK.
The second step is to stretch the heating wire as long as possible. In order to heat the entire vegetable cellar evenly, the heating wire must touch as much area as possible.
The last step is very simple, which is to lengthen the wire. The distance between the guard post and the depression below is at least 20 meters, so you must prepare a 30-meter-long wire.
Fortunately, when the temperature control probe was delivered, their electrician gave me several rolls of 2.5 square millimeter wire. This is a standard electric blanket wire. One roll is one hundred meters long, which is enough to pull the control wire.
Everything was ready, and five days had passed.
In fact, Lin Yi modified the heating equipment on the first day, but the system did not give him any invention points, probably because this kind of modification really did not constitute the element of invention.
However, Lin Yi didn't care. He had no place to use the invention point at all. If he gave it, he could only leave it alone without using it.
Making an insulated house is a big project. In fact, it is really simple to build an insulated house. The connecting pieces are tied with wires and then glued on, which makes them very secure.
The only time-consuming thing was shoveling the snow. It took two days to shovel a 5x5x5 snow pit.
Then I put down the insulated house and started to bury the snow.
The snow is buried very carefully. Although the insulated house is supported by steel bars, the weight of the snow is not small. In the Northeast, it is not uncommon for bungalows to collapse under the weight of snow.
But for everyone who often deals with snow, the solution is very simple.
Especially with Lin Yi's previous experience in creating ice and snow passages leading to dry toilets, the solution is even simpler.
We first sprinkle water on the snow outside the insulated house, and then use the ice and snow outside the insulated house as pillars. In this way, when laying the snow surface, most of the weight of the snow will be supported by the ice and snow next to it, which can greatly reduce
The stress level of the insulated house.
Lin Yi was very satisfied after seeing the joint work of all the members of Class 8. Building this insulated house was really a waste of effort.
But this was only the first step. After Lin Yi installed the temperature and humidity probes in the vegetable cellar and installed the electric heating equipment, he took everyone back to the gate and started to stare at the changes in the vegetable cellar.
Without the invasion of the cold wind, the temperature in the insulated house was not low, and soon reached around -5 degrees. It seemed that the snow layer five meters behind was enough to withstand the severe cold outside.
But in the area at the door of the vegetable cellar, the cold wind was still strong, at around ten degrees below zero. Lin Yi took out a pen and paper and wrote down this data.
Then he looked at everyone and said, "I'm using electric heating equipment now. Let's see how our insulation effect is."
In the empty vegetable cellar, there was only not too cold air, which heated up very quickly. Lin Yi set the electric heating temperature to five degrees above zero.
Because the electric blanket has its own temperature control, it can identify the specific temperature. However, since there is only one temperature probe, Lin Yi's focus is still on the ten temperature probes he has set up. What he needs is the overall temperature in the vegetable cellar, not the
The temperature of an area.
Soon, the temperature in the vegetable cellar rose to about five degrees above zero. Because the five-meter-thick snow layer and the insulation layer of the vegetable cellar itself greatly isolated the heat transmission, so even if Lin Yi turned off the
After turning on the electric heating equipment, after one hour, two hours, and three hours, the temperature did not change significantly. It only dropped by less than 0.5 degrees.
This also means that even if there is a power outage here in winter, the temperature of the vegetable cellar can be maintained at a relatively suitable temperature for a longer period of time.
Moreover, there is a generator in the outpost. Once the outpost has a power outage, it can generate electricity at any time to provide power for the vegetable cellar heating equipment.
The initial success of the experiment made Lin Yi quite satisfied, but after all, vegetables were not included, so the experimental data obtained now are still not rigorous.
In addition, the thermal insulation performance test after the power outage has not yet been completed, so Lin Yi was not in a hurry to put vegetables inside.
Lin Yi turned to look at everyone's excited expressions and smiled, "Okay, everyone, stop staring at the temperature control screen and go to bed early. We won't turn on the electric heating equipment tonight until twelve
After an hour, let’s check the heat preservation performance of the vegetable cellar.”
However, before going to bed, Lin Yi clearly saw many soldiers holding back their sleepiness and staring at the gate area from time to time on the pretext of going to the toilet. This was very bad. Lin Yi thought about it and immediately condemned it.
Don't look at it. Go to bed early and wait until tomorrow.
Deputy squad leader Zhu was surprised, Park Hae-jin, can we drink it? Yes, it’s better for me.
