doomsday survival

Chapter 283 Interconnection

I have to say that with electricity, life is indeed much more convenient. In addition to having electric lights for lighting, there are more surprises waiting for them.

This electrical appliance factory is a small household power plant, which produces a variety of products, and stores a large number of products in the warehouse.Although these products have been used for too long, they were all new products that had not been opened at the beginning, and they were well preserved in the warehouse. After some experiments, we still found a lot of good electrical appliances.

At the beginning, Shi Jian just wanted to go to the warehouse with electric heaters, and wanted to find some intact electric heaters, which would be used for heating everyone at night, so as to replace the charcoal basins. After all, these things are quite dangerous. If you are not careful, you will be prone to gas poisoning.

The entire warehouse is full of various types of electric heaters. In order to choose a suitable one, Shi Jian specially pulled a wire here, and then took the trouble to test one by one.

After some inspection, I found that there are quite a lot of electric heaters that can be used, whether it is the kind of oil-filled electric heater, or the siphon tube heat pipe electric heater that can be installed in the bathroom. Both are very high, while other types can be used significantly less.

Because of the high yield rate, Shi Jian quickly selected [-] electric heaters. He turned his attention to other warehouses and began to test them one by one.In the end, Shi Jian returned to the fire brigade with a bunch of kitchen appliances such as rice cookers and induction cookers.

There were more electrical appliances, and troubles followed. That night, because everyone used the electric heater together, the load on the electricity was too large. The burnt smell shocked many people, and no one knew where the smell came from.

Feng Chenzu ran to Shi Jian's room, knocked on the door, and said outside the door: "Boss Shi, hurry up and take a look, there is an unpleasant smell coming from somewhere, it's killing people."

Shi Jian and Feng Kuang were discussing where to focus the search tomorrow, and their room was at the back, so they really didn't smell anything.Hearing Feng Chen's words, Shi Jian sniffed carefully, then slapped his thigh suddenly, and said, "Quick, let them turn off the electric heater first!"

In fact, they are not the only ones. Only then did Shi Jian and Feng Kuang realize that both of them forgot one thing, that is, they forgot to add the electric switch protection switch. cause an electric fire.

After everyone turned off the electric heaters, Shi Jian asked everyone to continue to use charcoal for heating first, and then use the electric heaters after taking safety precautions tomorrow.

On the second day, Shi Jian put everything else aside, went to those old buildings to dismantle some intact air protection switches, and made some modifications to the circuit, so that everyone could continue to use these high-power electrical appliances.

Shi Jian also knows that the real hidden danger has not been completely solved. The most dangerous thing is not that there is no switch for protection, but that the wires he uses are too small, and he can't afford such a large power consumption.

But this didn't bother Shi Jian. Although he didn't have a suitable wire, he also had his own way.Although the wires in the small household power plant are small in size, they are also copper-cored, and there are quite a lot left over. Shi Jian directly stripped the outer sheath of the wires, twisted several strands of wires together, and used them for power supply.

Of course, unsheathed wires are more dangerous to use, but fortunately there is a small electric power plant here, and it also produces electric heaters, and there are a lot of fiberglass tubes for electric heaters piled up in the material warehouse.

Each roll of these fiberglass tubes has a length of 200 meters. Shi Jian used these fiberglass tubes as the insulation sheath of the wires, and only spliced ​​them once in the middle.Whether it is from the perspective of high temperature resistance or insulation, Shi Jian's self-made wires are very suitable for the current situation, which finally solves the hidden danger of electricity use.

After solving this problem, Shi Jian started a new round of large-scale search, but this search was not a big deal, but he found generators in several places one after another, such as the basement of the chemical plant laboratory building and several workshops. There are also generators of different powers in the research and development centers of pharmaceutical factories.

"Why are there so many generators here?" Shi Jian asked Feng Kuang puzzled.

Feng Kuang thought for a while and said: "This is considered a normal situation, because some experiments need to use electricity for a long time. Once there is a power outage, the whole experiment will have to be repeated. I have also seen those workshops. In the electrolysis workshop, if the power failure has a great impact on production, of course there must be a backup power supply."

Speaking of this, Feng Kuang sighed again, and said: "It seems that I am really old, and I even forgot this, otherwise, we would have had a power supply for a long time."

Seeing Feng Kuang's lost look, Shi Jian couldn't bear it, and comforted him: "Old Feng, it's been so long, how can you still remember so much, it's all normal, I don't forget it too A lot of things?"

Feng Kuang was silent for a while, then laughed again, and said, "It's nothing, I'm over 70 years old, and I'm thankful that I don't have Alzheimer's now, forgetting something is nothing."

Seeing that Feng Kuang was thinking about it, Shi Jian smiled and said, "Okay, what do you think we should do with so many generators, should we send two to the tribe?"

Feng Kuang shook his head and said: "It's useless to send it to them now, it's better to put it here first. Besides, if they don't use it well, and there are some problems, it will be bad."

Thinking of the mistakes he made two days ago, Shi Jian smiled helplessly, and said, "It's also the same reason. If one accidentally injures them by electric shock, it will be really bad."

But when they found the police station, their attitudes suddenly changed. They agreed that at least one generator should be sent to the cottage immediately, and a police radio station should be sent at the same time.

That's right, the biggest thing they found in the police station was the six vehicle-mounted police radios. As an outdoor enthusiast, Shi Jian couldn't help but want to know some knowledge about radio. There are also information about this in his mobile phone. content.

These six radio stations are all short-wave radio stations, one of which was installed in the police station, two were found on the police cars in the garage, and three were found in the police station’s equipment warehouse, and the supporting equipment was also found. antenna.What pleased Shi Jian the most was that among these antennas were high-energy half-loop antennas.

There are two main ways of short wave communication, one is ground wave and the other is sky wave.The ground wave propagates close to the ground, and gradually weakens due to the absorption of the land and ground, and disappears after more than ten kilometers, while the nearest landing point of the sky wave will be far away, so there will be a communication blind spot between the two.And this kind of high-energy half-loop antenna can produce "spout-like" high-elevation angle radiation, and the shortest distance to the sky wave landing is 0 kilometers, so there is no blind area, which is just in line with their current situation.

Although there are several mountains between the industrial park and the cottage, if antennas are installed on the top of the two mountains, wireless communication between the two places will be possible. This is really important for the current Chang'an tribe. up.

After discovering the radio station, Shi Jian was ecstatic, and immediately began to conduct power-on experiments. As for the 12-volt DC power required by the radio station, it was not a big obstacle to Shi Jian, as there were corresponding transformers in the electrical factory.

Shi Jian first found the information about the radio stations from his mobile phone, and then set up the antenna according to the above instructions. After connecting the radio stations one by one, he turned on the power and began to test each one.

After some testing, it was found that except for the two radio stations installed on the police car, the remaining four radio stations can be used normally.

"Old Feng, if you want to sleep, you can send me a pillow. We can finally keep in touch with our family." Shi Jian said happily to Feng Kuang.

"It seems that I can't do without sending two generators to my family," Feng Kuang said with a smile, "I'll send them back tomorrow."

Shi Jian nodded, and said to Feng Kuang: "Then I will go back tomorrow and set up the radio station for them. I have to work hard for you in the past few days. Search all other places to see what else is good. Things can be used."

"Okay, don't worry, take some electrical appliances back for them by the way, anyway, there are a lot of these things." Feng Kuang said.

Shi Jian smiled and said: "I want to go with me, I will go to see what other electrical appliances can be used in a while, and bring them a batch, but the electric heater is fine, we have no way to generate high-power electricity. Only the two small ten-kilowatt generators can be transported.”

Feng Kuang nodded and said: "Of course, the sled can't bear such a heavy weight. Besides, the high-power generators are more useful for us. Just give them two small ones."

After the two agreed, Shi Jian immediately returned to the small home appliance factory, where he found a bunch of intact electrical appliances, mainly kitchen appliances, and brought them along with wires and fiberglass tubes.

Quad sleds were used for the two small generators and the radio stations, electrical appliances and other materials to be brought back.Shi Jian took Feng Chen, Zhang Jian and Zuo Qian with him, and the four of them set off after lunch without waiting for the next day.

By noon on the third day, they had already returned to the village. Seeing them returning suddenly, the guards at the gate of the village were shocked, not knowing what had happened.After seeing the pile of items on Shi Jian's sledge, they realized that it was the beloved President Shi who had sent the supplies back.

Shi Jian chatted with them briefly, then drove straight into the village and found Xia Qianhe.

Xia Qianhe was also surprised by Shi Jian's sudden return, and asked, "Shi Jian, why are you back? Did something happen there?"

Shi Jian said with a smile: "Elder Elder, everything is normal in the industrial park and there is nothing wrong. I came back this time to bring you some useful things."

"What, I asked you to go all the way back. According to what I said before, when the supplies are delivered, let them bring them back." Xia Qianhe said nonchalantly.

"Not everyone can get these things, I have to come back in person." Shi Jian said with a smile.

"What is so expensive?" Xia Qianhe asked in confusion.

Shi Jian said softly: "The generator and the radio station."

When Xia Qianhe heard this, he stood up excitedly, and said in a trembling voice, "You mean the generator? The real generator is not the one you made yourself?"

"Of course, how can it be the kind I made myself, but it's a real generator." Shi Jian said.

"Quick," Xia Qianhe hurriedly grabbed Shi Jian's sleeve and said, "Take me to have a look."

Shi Jianhe led Xia Qianhe outside, and when he saw the generator on the sled, Xia Qianhe couldn't help but stepped forward to caress it, and murmured: "There will be electricity at last, real electricity! .”

Shi Jian smiled and said to him: "Elder Elder, don't just look at the generator, look over there."

Xia Qianhe heard the words and looked over, and saw a lot of boxes on a sleigh, and the graphics printed on it were exactly what he had dreamed about many times—electrical appliances.

"These, are these usable?" Xia Qianhe asked excitedly.

"I tested them one by one, and they all work, and I brought back a lot of wires and light bulbs. I will install them in every house tomorrow, and then everyone will have electric lights to use." Shi Jian said.

"Great! Don't wait for tomorrow, start now." Xia Qianhe said with a big smile.

Shi Jian shook his head helplessly, and said, "No way, Great Elder, I have to adjust the radio today, how can I have so much time?"

"What radio station? Radio?" Xia Qianhe asked puzzled.

Seeing that he didn't know, Shi Jian said, "Don't ask, let's talk while walking, let's go to the small house on the top of the mountain first, it is suitable for communication room."

When Xia Qianhe heard the word "communication room", he seemed to understand a little bit. While walking up the mountain with Shi Jian, he asked, "Is it like a telephone where both parties can communicate?"

"That's right, we found a few radio stations that can be used this time, and we just brought one back to see if we can get in touch with each other. If we can, then we can just talk about it on the radio station in the future. There is no need to run back and forth." Shi Jian explained.

"I didn't expect it," Xia Qianhe sighed, "You found so many good things there, I can't believe it."

Shi Jian said to Xia Qianhe: "Elder Elder, the old district is the wealth left to us by people in the old era. If we don't make use of it, it would be a pity to see these wealth disappear little by little."

Xia Qianhe nodded approvingly, didn't say anything, but secretly sighed in his heart: "Wang Lie, you really have seen too little, if you don't die, now you two should cooperate well, one Isn't our tribe getting better and better?"

With emotion, Xia Qianhe and Shi Jian came to the hut on the top of the mountain and watched Shi Jian start to set up the antenna.

This hut was originally used as a lookout post, but after many years of peaceful life, it became unused later, and now it happens to be used as a communication room for Shi Jian.

Shi Jian set up an antenna there, Feng Chen and Zhang Jian had already carried one of the generators into the house, and began to add diesel to it. It works.

Shi Jian checked it again, and after confirming that it was correct, he asked Feng Chen to shake the handle of the DC motor, and the generator roared.

"Fortunately, this DC motor is only used to start it, otherwise I would have to make one now." Shi Jian smiled and said to Feng Chen who stopped shaking the handle.

Feng Chen also smiled and said: "Yes, if the generator is running and the handle has to be cranked here, then I don't have to do anything, just crank it here."

Shi Jian smiled, connected the radio, and then shouted into the speaker: "Yangtze River, Changjiang, I am Huanghe, please answer."

There was no sound from the radio station, Xia Qianhe said with some disappointment: "Is this not working well, or the one over there is broken?"

Before Shi Jian could answer him, he heard Feng Kuang's voice from the loudspeaker: "When did you fail to communicate, boy, do you have to call when I go to the bathroom?"

Hearing that this was the reason why there was no response, everyone burst out laughing, Xia Qianhe also said with a smile: "Brother Feng is too interesting."

"Yangtze River, your voice is very good. How about my voice? Answer me when you hear it, and it's over." Shi Jian didn't joke with Feng Kuang, but asked seriously.

"Uh," Feng Kuang froze for a moment, then said, "Your voice is very good, over."

Shi Jian called again: "I will install the circuit for them tomorrow. If it goes well, I will return the day after tomorrow. I will contact you if there is anything else. It's over."

"Okay, be careful on the road, it's over." Feng Kuang cut off the contact after finishing speaking.

Shi Jian stood up and said to Xia Qianhe: "Elder Elder, it would be better to arrange someone to come here. I'll teach him how to operate this afternoon."

Feng Kuang thought for a while and said, "Look at women, can you do it? I remember that all the TV operators used to be women as operators."

Shi Jian nodded and said: "That's fine, women are careful, and can get started with these things faster, but if you are pregnant, don't come here, this thing may affect the fetus to some extent."

"Oh, that's it, then let that girl Yeyue come. This girl knows a lot, so she should be able to get started faster." Xia Qianhe suggested.

"Okay, but it's not enough for one person. It's best to arrange several people to work in shifts here to ensure smooth communication at any time. Let's find a few more." Shi Jian suggested.

"It's easy to handle. I'll just get a few more people to come later," Feng Kuang agreed, and then said to Shi Jian and the others, "You guys should also go down the mountain and have a rest, you've been exhausted for the past two days."

The four of Shi Jian went down the mountain with Xia Qianhe in a good manner, resting while waiting for Xia Qianhe to find the operator.
