Chapter 221 Finally, I am going to blow up the mountains and rivers (please give me a monthly ticket)


Chapter 221 Finally, I am about to explode the mountains and open the river (please ask for monthly tickets)

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

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

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

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

Xu Ye decided to use lightweight and high-strength composite materials to make the blades, which not only ensures the strength of the blades, but also reduces the overall weight and improves the fan's response speed.

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

When you are outside, you can't rub the brushless motor, but you still have a chance in the mechanical workshop.

Xu Ye became busy in the mechanical workshop, and he first drew detailed design drawings.

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

"Brushless motors are mainly composed of stator, rotor and electronic commutator..." Xu Ye recalled the knowledge in his mind while recording key information in his notebook.

He knew that when the coil on the stator was energized, a magnetic field would be generated, which interacts with the permanent magnet on the rotor, thereby realizing the rotation of the motor, and an electronic commutator was the key to controlling current commutation.

Xu Ye devoted himself to studying the structure and principles of brushless motors in the mechanical workshop.

While he flipped through the information, he recorded key design points in his notebook. "The coil of the stator 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 magnet of the rotor needs to be made of highly magnetic rare earth materials, such as neodymium iron boron, so as to generate a strong enough magnetic field."

"The design of an electronic commutator is crucial, it requires precise control of current. ”

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

Then, he began to make the stator.

"System, I want to redeem a 3D printer."

He wanted to redeem it before, but his mechanical properties were insufficient, so he did not redeem it.

[The mechanical properties are insufficient, it takes 500 mechanical properties to exchange for a basic 3D printer. 】

"So expensive?" Xu Ye couldn't help but complain. "It seems that you can only rely on these simple machine tools to rub your hands?"

Upgrade the machine tool?

Thinking about it, Xu Ye thought it would be better to forget it, and it would cost a lot of mechanical attributes to upgrade.

Anyway, there are three months left, and according to the progress of your previous work, you can rub five or six pieces by hand.

Wrinkle five or six units with your hands, and there is always one that can meet the standards, right?

And, just do it in one go as soon as you start, maybe it will be done in one go.

Xu Ye took a deep breath and decided to start making the brushless motor stator with the tools and materials at hand.

Although he does not have a 3D printer, he believes that with his skills and experience, he can still complete the task.

There are all kinds of materials in the mechanical workshop. If you don’t have one, you can use your own mechanical attributes to exchange them.

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

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

Although these equipment is simple, it is enough for him to start making brushless motor stators.

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

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

Xu Ye fixed the copper ingot to the lathe, adjusted the position of the tool, and began to carefully turn it. "Copper has too good thermal conductivity, and if you are not careful, it will overheat and deform." Xu Ye was whispering to himself while operating.

His hand steadily controlled the handle of the lathe, and the tip of the knife gently stroked across the surface of the copper ingot, making a subtle "hiss".

The copper chips rolled up like golden ribbons from under the tip of the knife and gradually stacked on the workbench.

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

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 fully meets the design requirements.

Next is to make the notch of the stator coil.

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

The diameter of the milling cutter is only a few millimeters and 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 hand steadily controlled the feed speed, and his eyes were staring at 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 accurately aligned, otherwise the coil will not be evenly distributed. "You can't be anxious, you must be steady..." Xu Ye said silently in his heart. A fine bead of sweat oozed from his forehead, but he didn't dare to distract himself.

The rotation speed and feed speed of the milling cutter must be perfectly coordinated. If you are not careful, it will lead to inconsistent notch depth and even damage to the copper ingot.

The time was almost done, so Xu Ye left the mechanical workshop and returned to the real world.

After returning, Jiang Ruoan and the others had already cooked the supper and were waiting for Xu Ye to eat.

As soon as the dinner was finished, the village radio rang, informing everyone that they would have a meeting at 7:30 pm.

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

But when he was training, Yang Zongming and Fan Dajun came to the door.

They came over to talk to Xu Ye about the content of the meeting tonight.

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

The Explosion of Mountains and Rivers has officially begun. A mobilization meeting will be held at night, and people will be selected to do this.

Xu Ye naturally supported this matter unconditionally, after all, he proposed it from the beginning.

They left after they finished speaking, not delaying Xu Ye's time.

Xu Ye's training is over, and it's almost time for the meeting.

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

When everyone was all together, Fan Dajun and Yang Zongming started talking with the microphone. "Friends, there is something big to discuss with you tonight." Fan Dajun's voice spread throughout the square through the loudspeaker, calm and powerful.

A whisper came from the crowd, and everyone had obviously guessed some clues. "I guess everyone has heard that our brigade is preparing to join forces with Shangxi Village to blow up mountains and rivers?"

"If the river is successfully opened, the time we will be shortened to half an hour, and the village can open a factory in the future." "At the same time, the bamboo rats raised in the village will be quickly transported outside for sale."

"If you want to be rich, build the road first. If we can't build the road, then build the river."

After saying that, Fan Dajun turned his attention to the villagers sitting below.

When the villagers heard Fan Dajun's words, they whispered and talked one after another. Some nodded in agreement, some showed hesitation, and some questioned in a low voice.

Xu Ye sat in the crowd, his eyes swept across everyone's expressions, and he understood in his heart that although the benefits of bombing mountains and rivers were obvious, the villagers' concerns about risks were reasonable.

At this time, Yang Zongming took the microphone, cleared his throat and said, "Friends, I know everyone has concerns. It is indeed no small matter to explode mountains and rivers, but we have made sufficient preparations." "Comrade Xu Ye personally designed the blasting plan, and the county experts also visited the field and believed that the plan was feasible."

"And, this action was not just from our village. Shangxi Village will also cooperate with all its strength. As long as we work together, this matter will definitely be accomplished! ”

Yang Zongming's words made the villagers feel a little relieved, but some people still raised questions. "Secretary Yang, will the explosion of the mountains cause the house in our village collapse?" an elderly villager stood up and asked.

Yang Zongming smiled and signaled Xu Ye to answer this question.

Xu Ye stood up, took the microphone, and said calmly, "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 from the village, and during blasting, we will use segmented detonation to minimize vibration."

Hearing Xu Ye's answer, the worries on the villagers' faces gradually dissipated, replaced by expectations for the future.

No mistakes, one poem, one post, one content, one in 6, one book, one bar, one read!

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

His words resonated with everyone, and many people agreed: "Yes, let's listen to Xu Ye!" ""I'm the one, I'm willing to do my best!" >


Seeing that everyone's emotions were mobilized, Fan Dajun struck while the iron was hot and said, "Okay! Since everyone supports it, let's hurry up and take action. Next, we need to select members of the blasting team to be responsible for the specific blasting work."

"This task is quite dangerous and requires bold and meticulous people. Those who are willing to participate can sign up."

As soon as the words were finished, several young people raised their hands.

"I sign up!"

"I will participate too!"

Fan Dajun nodded, showing a gratified smile on his face: "Okay, everyone is very active, I have seen good days wave to us."

In the following time, Fan Dajun and Yang Zongming All work has been arranged in detail.

From the transport of explosives to the cleaning after blasting, each task is assigned to specific people.

The meeting lasted until after ten o'clock in the evening, and everyone left one after another.

After going back, Xu Ye and Jiang Ruoan and the others chatted for a while.

Although they had known for a long time that Xu Ye was pushing for the explosion of mountains and rivers, they were still very excited when this day really came.

Once the river is successfully opened, the traffic pattern will be directly changed.

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 will take down all the contents of junior high school and will only have time to learn high school contents next year.

So, their time is still very tight.

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

Then, I entered the mechanical workshop as soon as possible and continued to rub the generator's stator with my hands.

After several hours of hard work, the notch of the stator was finally completed.

Xu Ye took off the copper ingot and carefully inspected each notch with a magnifying glass.

The edges of the notch are smooth and have a uniform depth, which fully meet the design requirements.

He breathed a sigh of relief and wiped the sweat from his forehead.

Originally, he thought the first one he made would not succeed.

Now it seems that my success rate is quite high.

Of course, it is mainly related to the size of the stator he made.

The smaller the process, the harder the process and the higher the failure rate.

After having the stator, everything is much simpler.

But today should be over, and it's still late.

Therefore, Xu Ye directly withdrew from the mechanical workshop and returned to reality.

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

Xu Ye rinsed it briefly and then went back to bed.

The mountains will start to explode tomorrow, and Xu Ye has to go and take a look, and he also has to guide them to use a wind drill rig to drill holes.

Fan Dajun went to his brother-in-law for a lot of contact, and then he got a wind drilling rig.

Because Xu Ye said that he would use a wind drill rig and informed them of the advantages of the wind drill rig.

Otherwise, they are planning to pierce holes manually.

The next morning, Xu Ye got up early. After a simple breakfast, he gathered with the drilling group selected by the village.

After the brigade headquarters, Xu Ye saw the typhoon drilling rig.

Although the machine looks a bit old, it is well maintained. It is obviously specially selected by Fan Dajun's brother-in-law.

Xu Ye walked forward, looked carefully, and thought about the structure and principles of this machine in his mind. "Xu Ye, Master Feng Zao hasn't come yet. Are we going to enter the mountain now?" Fan Dajun said with some distress.

As agreed, the other party should have come last night.

So far, no one has been seen yet.

He was worried that something would happen to the other party, so he had sent two people to find someone along the way.

"It doesn't matter. I can use this thing too. Just have a machine here." Xu Ye said calmly.

In his previous life, he also used to shoot wind drills and was an old gunner.

Xu Ye has done most of the work on the construction site. "That's great, I knew you would. Then, I'll leave this job to you first. Teach them all, so you don't have to be busy." Fan Dajun patted Xu Ye's shoulder. , said with a smile.

Xu Ye nodded without refusing. He put on his hard hat, walked to the wind drill, and began to debug the machine.

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

Xu Ye explained the precautions to the villagers next to him.

After a while of explanation, Xu Ye asked everyone to carry the wind drill rig to their destination.

Along the way, everyone was nervous and excited. After all, this was the first time in the village to carry out such a large-scale project.

The trees in the mountain were cut down by the villagers, and they arrived in less than an hour.

Now, what Xu Ye and the others saw was the rocky mountain, which was also the place where they would drill and blast for a long time next.

How to choose a position is also very skillful, and it also tests the ability of a wind drill master.
