Return to the era, take over and become a winner in life

Chapter 221: Finally, we are going to blow up the mountain and open the river (asking for monthly tickets)

Xu Ye took a deep breath and began to carefully analyze the details of the task.

An 80-kilowatt wind turbine not only requires a strong mechanical structure to support it, but also a sophisticated electrical system to ensure power generation efficiency.

The first thing he thought of was the design of the fan blades.

The shape and material of the blades directly affect the efficiency of wind energy conversion.

Xu Ye decided to use lightweight and high-strength composite materials to make blades, which would not only ensure the strength of the blades, but also reduce the overall weight and improve the response speed of the fan.

Next is the generator part. The 80-kilowatt generator requires an efficient electromagnetic conversion system. Xu Ye plans to use a brushless motor.

You can't rub a brushless motor by hand outside, but there is still a chance in a mechanical workshop.

Xu Ye was busy in the mechanical workshop. He first drew a detailed design drawing.

After drawing the design, Xu Ye began to study the brushless motor.

"The brushless motor is mainly composed of a stator, a rotor and an electronic commutator..." Xu Ye recalled the knowledge in his mind while recording the key information in his notebook.

He knew that when the coil on the stator is energized, it will generate a magnetic field, which will interact with the permanent magnet on the rotor to achieve the rotation of the motor, and the electronic commutator is the key to controlling current commutation.

Xu Ye was concentrating on studying the structure and principles of brushless motors in the mechanical workshop.

As he flipped through the materials, he wrote down key design points in his notebook.

"The stator coil needs to use copper wire with high conductivity, which can reduce energy loss and improve the efficiency of the motor." Xu Ye said to himself.

"The permanent magnets of the rotor need to be made of strong magnetic rare earth materials, such as neodymium iron boron, so that they can generate a strong enough magnetic field."

“The design of the electronic commutator is critical because it requires precise control of the direction and magnitude of the current to ensure the motor can run smoothly.”

Xu Ye drew a structural diagram of the brushless motor in his notebook and marked the dimensions and material requirements of each component.

Next, he started making the stator.

"System, I want to exchange for a 3D printer."

He had wanted to exchange it before, but the mechanical attributes were not enough, so he didn't exchange it.

[Insufficient mechanical attributes. 3 mechanical attributes are required to exchange for a basic 500D printer. ]

"So expensive?" Xu Ye couldn't help but complain.

"It seems that we can only rely on these simple machine tools to rub by hand?"

Upgrading machine tools?

After thinking about it, Xu Ye decided to forget it. If he wanted to upgrade it, it would cost a lot of mechanical attributes.

Anyway, I have three months, and according to my previous work progress, I can make five or six machines by hand.

If you rub five or six machines by hand, there must be one that meets the standard, right?
Moreover, if you start with a big plan from the beginning, you may be able to get it done in one go.

Xu Ye took a deep breath and decided to use the tools and materials on hand to start making the stator of the brushless motor.

Although he doesn't have a 3D printer, he believes he can still complete the task with his skills and experience.

The mechanical workshop has all kinds of materials. If you don’t have any, you can exchange them with your own mechanical properties.

After selecting the suitable materials, Xu Ye began to process the stator.

Xu Ye stood in front of the workbench in the machine workshop, his eyes sweeping over the several basic machine tools in front of him - an old lathe, a manual milling machine and a small drilling machine.

Although these equipments were rudimentary, they were enough for him to start making stators for brushless motors.

He first took a high-conductivity copper ingot from the material rack, which is the key material for making stator coils.

The copper ingot is heavy, with a faint metallic luster on the surface.

Xu Ye fixed the copper ingot on the lathe, adjusted the position of the tool, and began turning it carefully.

"Copper has such good thermal conductivity that it will overheat and deform if you're not careful."

Xu Ye was operating while muttering to himself.

His hand steadily controlled the handle of the lathe, and the tip of the knife gently scratched the surface of the copper ingot, making a slight "hissing" sound.

Copper shavings rolled up from under the tip of the knife like golden ribbons, gradually piling up on the workbench.

After turning was completed, Xu Ye took out the copper ingot and carefully measured the size with a caliper.

The error must be controlled within 0.1 mm, otherwise the performance of the stator will be greatly reduced.

He adjusted it several times until the size was exactly what he wanted.

Next is to make the notches for the stator coils.

Xu Ye transferred the copper ingot to the milling machine and installed a tiny milling cutter.

The diameter of the milling cutter is only a few millimeters and it will break if you are not careful.

He took a deep breath, aimed the milling cutter at the surface of the copper ingot, and slowly started the machine.

"Buzz--" The milling machine made a low roar and the milling cutter began to rotate at high speed.

Xu Ye's hands steadily controlled the feed speed, and his eyes were fixed on the position where the milling cutter contacted the copper ingot.

The milling cutter draws fine grooves on the surface of the copper ingot, and each groove must be precisely aligned, otherwise the coils cannot be evenly distributed.

"Don't be impatient, you must be steady..." Xu Ye said silently in his heart. Fine beads of sweat oozed out of his forehead, but he didn't dare to be distracted.

The milling cutter's rotational speed and feed rate must be perfectly coordinated. Any inadvertent mistake will result in inconsistent notch depths or even damage to the copper ingot.

Calculating that the time was about up, Xu Ye left the mechanical workshop and returned to the real world.

After returning home, Jiang Ruoan and the others had already prepared dinner and were waiting for Xu Ye to eat.

Just after dinner, the village radio sounded, informing everyone that a meeting would be held at 7:30 in the evening.

Xu Ye and his friends had breakfast quite early, as there was still some time before 7:30, so he went to train hunting dogs and goshawks.

However, while he was training, Yang Zongming and Fan Dajun came to visit.

They came here to inform Xu Ye about the content of tonight's meeting.

After the communication, Xu Ye knew what they were going to do.

When the work of blasting mountains and opening rivers officially begins, a mobilization meeting will be held in the evening, and people will be selected to do this work.

Xu Ye naturally supported this matter unconditionally, after all, he was the one who proposed it in the first place.

After they finished talking, they left without wasting Xu Ye's time much.

Xu Ye finished his training and it was almost time for the meeting.

So Xu Ye and the others took the benches and walked towards the brigade headquarters.

After everyone was present, Fan Dajun and Yang Zongming took the microphone and began to speak.

"Fellow villagers, I have called you all here tonight because I have something important to discuss with you." Fan Dajun's voice spread throughout the square through the loudspeaker, steady and powerful.

There was a whisper among the crowd, and everyone had obviously guessed something.

"I guess everyone has heard that our brigade is planning to join forces with Shangxi Village to blast the mountain and open the river, right?"

"If the river is successfully opened, the time it takes us to get to town will be reduced to half an hour, and we can open a factory in the village in the future."

"At the same time, the bamboo rats raised in the village are also quickly transported outside for sale."

“If you want to be rich, build roads first. If we can’t build roads, then build rivers.”

After saying this, Fan Dajun turned his gaze to the villagers sitting below.

When the villagers heard Fan Dajun's words, they began to talk among themselves. Some nodded in agreement, some looked hesitant, and some even whispered doubts.

Xu Ye sat in the crowd, his eyes scanning everyone's expressions. He knew in his heart that although the benefits of blasting mountains and opening rivers were obvious, the villagers' concerns about the risks were understandable.

At this time, Yang Zongming took the microphone, cleared his throat and said: "Fellow villagers, I know everyone has concerns. Blasting mountains and opening rivers is indeed not a trivial matter, but we have made sufficient preparations."

"Comrade Xu Ye personally designed the blasting plan, and county experts also came to investigate on the spot and believed that the plan was feasible."

"Moreover, this operation is not just about our village. Shangxi Village will also fully cooperate. As long as we work together, this will definitely succeed!"

Yang Zongming's words made the villagers feel a little relieved, but some people still raised questions.

"Secretary Yang, will blasting the mountain cause the houses in our village to collapse?" an elderly villager stood up and asked.

Yang Zongming smiled and motioned Xu Ye to answer the question.

Xu Ye stood up, took the microphone, and said in a steady tone: "Don't worry, the location of the blasting point and the amount of explosives have been accurately calculated and will not affect the village."

"The blasting point we chose is a safe distance away from the village, and the blasting will be carried out in sections to minimize vibration."

After hearing Xu Ye's answer, the worries on the villagers' faces gradually dissipated, and were replaced by expectations for the future.

At this time, a young man stood up and said loudly: "Xu Ye, if you say it's okay, let's do it! Our village has been poor for many years. If we can really open the river and build a road, we will have hope for the future!"

His words resonated with everyone, and many people echoed: "Yes, let's listen to Xu Ye!"

"Count me in, I'm willing to help!"

Seeing that everyone's emotions were aroused, Fan Dajun said, "Okay! Since everyone supports it, let's take action as soon as possible. Next, we need to select members of the blasting team to be responsible for the specific blasting work."

"This mission is quite dangerous and requires someone who is brave and careful. Anyone who is willing to participate can sign up."

As soon as he finished speaking, several young people raised their hands.

"I regestrated!"

"I'll join in too!"

Fan Dajun nodded with a pleased smile on his face: "Okay, everyone is very positive. I can see that good days are waving at us."

In the following period of time, Fan Dajun and Yang Zongming arranged each task in detail.

From the transportation of explosives to the cleanup after the blast, each task was assigned to a specific person.

The meeting lasted until after ten o'clock in the evening, when everyone gradually dispersed.

After returning, Xu Ye and Jiang Ruoan chatted for a while.

Although they had known for a long time that Xu Ye was pushing for blasting mountains and opening rivers, they were still very excited when the day finally came.

Once the river is opened successfully, it will directly change the traffic pattern.

The more I think about it, the more I look forward to it.

Not many people are willing to be in a closed environment, they have no choice here.

If so, they still want to leave.

After chatting for a while, they went to study.

This year they have to complete all the junior high school content, and only next year will they have time to learn the high school content.

Therefore, their time is still very tight.

Xu Ye did not waste any time and went straight into his studio.

Then, he immediately entered the mechanical workshop and continued to rub the stator of the generator by hand.

After several hours of hard work, the stator slots were finally completed.

Xu Ye took down the copper ingot and carefully examined each groove with a magnifying glass.

The notch edges are smooth and the depth is uniform, fully meeting the design requirements.

He let out a long sigh and wiped the sweat from his forehead.

Originally, he thought the first one he made would not be successful.

Now it seems that my success rate is still quite high.

Of course, it mainly has to do with the size of the stator he made.

The smaller it is, the more difficult the process is and the higher the failure rate is.

With the stator, everything becomes much simpler.

But today should be coming to an end, it’s getting late.

So, Xu Ye directly quit the mechanical workshop and returned to reality.

Jiang Ruoan and the others had also finished their studies and had gone back to their rooms to rest.

Xu Ye simply took a shower and went back to sleep.

The mountain blasting will start tomorrow. Xu Ye will also have to go and take a look. He also has to instruct them on how to use the pneumatic drill to drill holes.

Fan Dajun used a lot of connections from his brother-in-law and finally got a pneumatic drill.

Because Xu Ye said he would use a pneumatic drill and told them the advantages of the pneumatic drill.

Otherwise, they plan to rely on manual drilling.

The next morning, Xu Ye got up early, had a simple breakfast, and then gathered with the drilling team selected from the village.

When he arrived at the brigade headquarters, Xu Ye saw the pneumatic drilling rig.

Although the machine looked a bit old, it was well maintained and was obviously specially selected by Fan Dajun's brother-in-law.

Xu Ye walked forward, looked at it carefully, and secretly pondered the structure and principle of the machine.

"Xu Ye, the pneumatic drill master hasn't arrived yet. Do we still need to go into the mountains now?" Fan Dajun said with some distress.

According to the agreement, the other party should have come last night.

As a result, no one has been seen so far.

He was worried that something might have happened to the other party, so he sent two people to look for him along the way.

"It's okay. I can use this thing, too. As long as I have the machine, it's fine." Xu Ye said calmly.

In his previous life, he also worked with a pneumatic drill and was an experienced gunner.

Xu Ye has done most of the work on the construction site.

"Great, I knew you could do it. Well, I'll give this job to you first. Once you teach them all, you won't have to worry about anything else." Fan Dajun patted Xu Ye's shoulder and said with a smile.

Xu Ye nodded without refusing. He put on his helmet, walked to the pneumatic drill, and started to debug the machine.

The operation of a pneumatic drill is not complicated, but it requires certain skills and experience.

While operating, Xu Ye explained precautions to the villagers next to him.

After explaining for a while, Xu Ye asked everyone to carry the pneumatic drill to the destination.

Along the way, everyone was nervous and excited. After all, this was the first time that the village had undertaken such a large-scale project.

All the trees in the mountain had been cut down by the villagers, and it took them less than an hour to reach the destination.

Now, in front of Xu Ye and his team is a rocky mountain, which is also the place where they will drill and blast for a long time.

Choosing a location requires skill and is a test of a pneumatic driller's abilities.
