The manganese batteries used in the radio eventually ran out of power. Originally, the 284th Division had several generators, but they were lost one after another in the tragic war, or were simply blown up and burned.
In World War II, radios have been widely used in warfare. During the war, between the Soviet Union and Germany, the Germans had more advanced application technology, especially in the tank unit. The commander of the armored regiment could use radio to command all 152 tanks.
The Soviet army did a relatively poor job in this regard. After Kuznetsov left, they did not leave any batteries behind. After successfully communicating with the Soviet army in the southern part of the swamp, they made an emergency transfer, leaving only the remaining batteries in the swamp.
Three radio stations.
The technology of batteries in this era was not high and the power reserve was very limited.
Without the radio, everyone seemed to be abandoned. Yevlov had no choice but to hope that Belekov would come up with new ideas.
Yang Mingzhi thought for a moment and suddenly had an idea: "Yevlov, are all the trucks outside the swamp powered by electric ignition?"
"Of course, those ZIS-5 trucks have excellent performance. You mean to use the truck's battery instead of the radio?"
"Maybe it's possible." Yang Mingzhi said calmly, "I guess the specifications of the two batteries must be different, so in order to adjust it to a voltage that the radio can use, we have to make a transformer."
Making a transformer? Yevlov doesn’t know much about this? “Maybe we should invite professional electronic experts? Can you do it yourself? Or are you an expert?”
Yang Mingzhi just smiled. After the meeting, he took away the battery and ordered the car to be dismantled, and the battery to be dug out of the car and sent to the swamp as soon as possible.
In fact, making do with car batteries is really a helpless move. Yang Mingzhi didn't know how Tubal Road in China solved the energy problem of radio stations in this era. It was probably a gasoline generator or a manual hand-operated generator.
If we use human power to generate electricity for the radio station, in theory, it may be feasible given the current situation in Catfish Village. He noticed the villagers' bicycles, and perhaps a large-scale modification could be used to create a reliable human-powered generator.
I borrowed an iron pot from a villager, but that family said there was no need to return it.
In the evening, Carambola used this to cook a pot of fish soup. Cut the caught catfish into sections, add cabbage, and sprinkle with salt. The aroma attracted many people. These soldiers just smelled it, and they would never rob the commander.
A delicious meal. When the officers came back, they all saluted.
"You all go back." Yang Mingzhi waved his hand.
Yang Tao noticed that her husband seemed to have something on his mind. He frowned and held a dark object in his hand.
"Come on, have some fish soup, I made it delicious."
Yang Mingzhi has been thinking about the battery. He is sitting on the wooden post that serves as a stool, holding the battery in his hand. The deliciousness of the food does not even attract his attention, as long as the star fruit makes a sound.
"Oh! What did you say just now?"
"You really are holding the black bump and don't think about food or tea." Star Tao pouted.
She was like a housewife. After the training in the morning, she returned to her residence and continued to repair the wooden house she had built with a few soldiers. Now at least it is very suitable as a "forest cabin". The dining table and stove are outside the house.
, we have to continue building a house and a kitchen, so we’ll just make do for now.
Star fruit handed her husband a piece of bread. "Eat it, you have to have a full stomach if you want to do research."
Yang Mingzhi smiled and placed the battery on the table.
The two had dinner together. To be honest, this girl's cooking was pretty good. After all, she was a farm girl. Compared to the girls of the next century, she was really virtuous. "Hey, Xiaotao, are your shoulders still sore now?"
"
"It's okay, it's just a little sour. If I really can't stand it anymore, I guess I won't even have time to cook at that time."
"Okay, you have to take care of yourself too. There will be shooting training in the future."
After eating, Yang Mingzhi was still worried about the battery. At night, the soldiers lit some bonfires. There was no power station near Catfish Village. In this era, most villages in the Soviet Union did not have electricity. Farmers still used this sunrise to make sunrise.
It is a habit to live by breathing in and out, but at night, candles and oil lamps are very popular.
Old Ivan, the blacksmith in the village, has been extremely busy since the army entered the swamp. Many firearms need to be repaired, and his skills are of great use.
That night, an uninvited guest came to visit. The next day, he had a foreign face. He was very polite to others, and they became friends. "Berekov, you came here so late, do you still want to ask me about the bullet casings?"
thing?"
His wife brought half a bottle of wine. She knew that a conversation between men cannot be complete without a drink.
"Aunt Kaya, no need. I won't be here long this time." Yang Mingzhi waved his hand. He saw this old guy repairing the bullet disc of the DP machine gun, and some parts were deformed. Old Ivan had to use violent methods to remove it.
The deformed part was knocked back. The sound of snapping echoed in the room.
"So, you came here to ask about gunpowder?" Old Ivan asked absently.
"No, Uncle Ivan, I just want to ask you if you have any copper wire or silicon steel sheets here."
Old Ivan stroked his beard, "What do you want? I have copper wire. Silicon steel sheet? Silicon steel?!"
What he said was so professional that this guy probably couldn't understand it. Yang Mingzhi simply said that if he wanted to make a generator, he must have magnets, coils, and silicon steel sheets.
Old Ivan put down what he was doing and said, "Follow me to the warehouse and take a look. Maybe you can use this machine."
The warehouse was a wooden shed, and the machine Old Ivan was talking about was a scrapped diesel generator. When he saw this, Yang Mingzhi was shocked, "You still have this thing!"
Old Ivan held his pipe and recalled what happened many years ago. When he moved the machine into the village, he simply wanted to solve his own electricity problem. Later, because it was too expensive to buy diesel, the machine fell into disuse. Over time,
Just scrap it completely.
"The last time I used it, the diesel oil leaked and it caught fire. After I put out the fire, the machine could no longer be used. I heard that you need a motor, and there is one in it." Old Ivan pointed at the machine, with Yang Mingzhiman on his side.
Smiling face.
"Okay, let's just dismantle it completely."
That night Yang Mingzhi was at old Ivan's house, and it was impossible to just sit for a while and then leave. He was afraid that his wife would be lonely guarding the house alone, so he ordered the soldiers to call Carambola over. His wife was still a child, and it was very necessary to educate her in all kinds of knowledge.
, and at the same time it would be good for her to make a start.
Eventually, the generator was separated from the entire machine, and Yang Mingzhi removed the rotor.
"Magnetism generates electricity, and electricity generates magnetism. Let's change its power generation now." Yang Mingzhi said to Yang Tao. How could she understand this, but she thought her husband was very powerful.
Yang Mingzhi did have this ability. With the dim light of the oil lamp, he was performing a bunch of physical calculations and finally calculated the length of the coil that should be wound. The rest was relatively simple. He removed a part of the silicon steel sheet, which was used to make the transformer.
The "iron core". Silicon steel is very precious, so it must be used to its best advantage.
Throughout the night, several people at old Ivan's house were busy making machines. This scene reminded Yang Tao of a few months ago, when her husband would stay late studying weapons.
After a night of hard work, Yang Mingzhi was exhausted. He and old Ivan both had a craftsman spirit and were extremely excited to study the machine. Yang Tao couldn't bear it at all, so the hostess arranged for him to rest, and he was spared another day of military training.
After putting in a lot of effort, Yang Mingzhi felt that his calculations were correct. The electric motor was connected to Old Ivan's bicycle. The rear tire of the bicycle was removed and replaced by a belt that was put on the wheel hub. The belt was also connected.
Engine. In this way, a person riding a bicycle can turn the rotor and the machine can generate electricity smoothly.
As for the transformer, the silicon steel sheet was processed by old Ivan. The inscription on the manganese battery is very clear. The working voltage required by the radio station is not so abnormal. The simple version of the transformer currently only made can be used.
Yes, the machine is very simple. The transformer is just a bunch of coils wound around each other. There is no insulator attached to the copper wire, so we have to simply wrap the copper wire with cloth. Overall, the machine looks silly, big, black, and thick, but according to calculations, it
The battery can now be charged.
Yang Mingzhi couldn't bear it anymore, so his wife woke up first early in the morning.
"Xiao Tao, I have a task for you, ride on the bike and pedal hard." Yang Mingzhi thought that his wife knew how to ride a bike. This was purely natural. Yang Tao was confused about bikes and was even a little scared. She still obeyed her husband's orders.
Fortunately, the bicycle has been fixed at this moment, and she will definitely not fall off.
Yang Mingzhi planned to check the situation first. The wires were all connected. Carambola on one side was already pedaling hard, and electric energy was being continuously input into the battery.
Yevlov and Yelentina yawned. They did not find Berekov at his residence. The soldier informed the officer that the couple had gone to the blacksmith.
So when these two people came to Old Ivan, they directly saw their strange behavior.
Yang Mingzhi had dark circles under his eyes and was in very bad spirits. He made a gesture symbolizing victory. "Yevlov, I think I have succeeded. These are our generators and transformers. You can install the batteries into the radio station later and try
For a moment. I'm going to bed first."
Yelentina knew better. She couldn't build machines herself, but she could also tell that this should be a charging device. "This Belekov, is he really an expert in mechanics and electricity? Yevlov
, do you know his past?"
Yevlov shrugged: "Who knows? Instead of asking me, the Chinese on the other side of the Amur River, you might as well ask Besica. You see, this girl is still struggling to ride her bicycle. I guess you have to wait for her.
Ask again when you are tired."
