Otaku Engineer in Great Tang Dynasty Chapter 1424: Flick away, DC generator!

"Master, it's not good!"

South of Chang'an City, Lin's backyard.

The maid Xiaoshi ran into the study with the latest issue of "Datang Daily", and said to Lin Hao who was sitting in front of the bookcase reviewing his homework.

"What's wrong? What's wrong? Don't bother me with small things!"

Since the beginning of the new year, Lin Hao has been in retreat to prepare for the exam. At the end of March, although he knew Pi Xiake had opened a new book, in order to be admitted to Yanhuang Academy this year, he could only reluctantly cut his love, and for the time being "Zhu Xian" Put it aside, he plans to wait until the exam is over and watch it together!

Several of his servants got his order to buy a copy of "Da Hua Jiang Hu" every day, and cut out the part about "Zhu Xian" in it, bound them into a book, and kept them until he finished the exam. .

"Master! At the finale of "Zhu Xian" today, Pi Xiake said later that he would completely close his pen and no longer write novels~! The "Datang Daily" office in Chang'an City has gathered a lot of readers and they are all crazy Give a reward and ask Pi Xiake not to seal the pen!"

Xiao Shi took the latest issue of "Da Hua Jiang Hu" and said breathlessly.

"What? "Zhu Xian" is coming to an end? Pi Xia Ke is going to seal his pen?"

When Lin Hao heard this, he stood up with a shocked look. He originally planned to raise "Zhu Xian" first, but he never expected that this support would directly feed the author! This level of book raising is estimated to be difficult for anyone to surpass in the future, right?

"Hmm! Master, look!"

Xiao Shi nodded in response, and handed Lin Hao the "Da Hua Jiang Hu" in her hand.

Lin Hao took it, carefully read the last paragraph above, and finally couldn't help but sighed: "Ah! What a pity! What a pity! I will never see his novels again! Poems , You go get one thousand Tang Yuan and reward Pi Xia Ke!"

Now the bicycles of the Yanhuang Chamber of Commerce have sold well across the country. Lin Wenyuan has made a lot of money by virtue of his status as a member of the Chamber of Commerce. In addition, Lin Hao has been in retreat for exams recently, and it is rarely useful to get money, so this The kid also saved a lot of private money, and one thousand Tang Yuan can still afford it!

"Yes! Master!"

"Brother Qingque, Brother Xiaoxuan really doesn't plan to write novels in the future?"

In the imperial palace, the little fat man had just greeted him from Empress Changsun, he was "robbed" by Changle. Changle took Li Tai to the garden and asked urgently.

Li Tai sighed and said helplessly: "I just learned about this too! Although I feel uncomfortable, I understand Shan Chang, he has so many things in his daily life, how can there be time to write novels! This result should have been long ago. You are mentally prepared!"

When Changle heard the words, a touch of sadness appeared on her face. After a while, she nodded and said: "Yeah! Brother Qingque, you are right. Brother Xiaoxuan can never write novels for us all the time. He is now Not only in charge of Yanhuang Academy, but also in charge of the huge fief in Lantian County, I should stop writing~! However, from now on, it will be difficult to see such a wonderful novel as "Zhu Xian" again!"

"Shanchang, do you really plan to seal the pen and not write?"

In the new workshop of Qiquge.

Li Zexuan came here today to observe the progress of the technological transformation and upgrading. By accident, he met Ma Zhou. Ma Zhou took Li Zexuan to a corner and asked with a sad look.

"Oh! Don't write anymore! Don't write anymore! Benhou is getting busier and busier now, there is no time to write novels!"

Li Zexuan waved his hand and said with a wry smile.

Ma Zhou was unwilling to say: "But, Lord Hou, do you really want your readers? Do you know that this morning, countless readers of "Zhu Xian" in and around Chang'an City, more than 20 prefectures and counties The "Datang Daily" office gave you a reward. They want to apologize for the previous trouble in the workshop and keep you in this way! Are you really willing?"

Although I had decided to seal the pen after writing "Zhu Xian", now that Ma Zhou talked about it, Li Zexuan's heart still couldn't help feeling a little uncomfortable. It was a kind of reluctance.

"There is no permanent banquet in the world. Benhou has more and more affairs, and it is impossible to write it down all the time. Long pain is better than short pain. Taking advantage of the fact that they are still "not deep in", I got out early Besides, the waves behind the Yangtze River pushed the waves forward. Now Hua Hongyi's "Menghui Daqin" is gaining momentum and has a chance to replace the number one position in "Zhu Xian". After things go away, I hide my merits and fame. , Not only to make way for young people, but also to avoid being overtaken by others in the future and becoming embarrassed!"

After a moment of silence, Li Zexuan shook his head and said.

Ma Zhou took a deep look at Li Zexuan, and said, "Fuck off your clothes when things are gone, and hide your merit and fame. Lord Hou is a good literary talent! Although Lord Hou is very reasonable, Ma does not believe a word! The status of "Zhu Xian", whether it was before or in the future, absolutely no one can shake! "Menghui Daqin" has become more and more exciting after the revival, but compared with "Zhu Xian", it is still a bit worse!"

The last time Li Zexuan told Hua Hongyi about the TV series "The Myth" of his previous life, Hua Hongyi stopped for a week and re-planned the outline. After the renewal, "Menghui Daqin" is undoubtedly more exciting in the plot!

Engineering students Hua Ziyu, Princess Tuan Guoyushu, King Xiang Yu of Western Chu, Liu Bang, General of the Great Qin, Meng Yi, the **** Zhao Gao, Fusu, the second son Hu Hai, the ninety-five supreme Qin Shihuang, these characters In Hua Hongyi's pen, there was a dazzling spark!

m

Especially the fragments in the book where the protagonist Hua Ziyu uses engineering to do things in the Qin Dynasty, readers are all overwhelmed by it!

Because of this, the performance of "Menghui Daqin" is getting better and better, and there is even a faint surpassing of "Zhu Xian"! Nowadays, there are more and more novels imitating "Menghui Daqin", such as "Menghui Three Kingdoms" and "Menghui Dahan" are everywhere, basically all imitating "Menghui Daqin" the protagonist dreams of returning to before The model of the dynasty, it can be said that "Menghui Daqin" can be regarded as the first of the genre of "crossing history"!

Seeing that "Menghui Daqin" became more and more popular, Li Zexuan was relieved to completely seal the pen.

After listening to Ma Zhou's words, Li Zexuan said helplessly: "Haha! Brother Ma really can see Ben Hou, but the matter is over, Ben Hou will never write novels anymore. In the future, Brother Ma will find out more. Some potential new talents are!"

Ma Zhou saw that Li Zexuan had decided, he could only sigh helplessly, shook it, and went away with his hands behind his back.

Li Zexuan stood quietly on the spot, looking at Ma Zhou's leaving back, after a while, he turned and walked towards Mo Lingwei's laboratory.

"Xiao Ningzi, come here and help wind the coil on the magnet!"

"Oh oh! Here comes!"

"Hey! Can you stop shaking your hands! Be serious!"

"I didn't shake it! It's because it shakes itself, I can't control it!"

"You can't control your hands, who can control it?"

"No"

As soon as he walked to the door of the laboratory, he heard the quarrel between the enemies, Li Zexuan couldn't help shook his head and pushed in.

"Ahem~! Miss Mo, Shaoning, are you assembling a motor?"

At this time, because they were assembling the electric motor together, the heads of Yan Shaoning and Mo Lingwei were only less than one centimeter apart. They looked very ambiguous. Li Zexuan couldn't help coughing, pretending not to see it, and said.

Hearing the sound, Mo Lingwei hurriedly bounced away from Yan Shaoning as if she had been electrocuted, and a flush of blush quickly appeared on her cheeks. She twisted her hands together and hurriedly said: "The long mountain, you Yes! Oh, I will finish that motor soon and I will hand it over to you tomorrow at the latest!"

"So fast!"

Li Zexuan looked at the motor housing and various parts scattered all over the floor. He nodded with satisfaction and said: "Ms. Mo's attainments in electrical machinery are really becoming more and more sophisticated! Although the principle of this motor is It's simple, but it's not easy to make it in practice. Miss Mo can make it in just five days, which is really impressive!"

Hearing Li Zexuan’s praise, Mo Lingwei couldn’t help but smile, but she thought that she was a professor at Yanhuang Academy and should be reserved, so she quickly suppressed the smile on her face and said: "Shanchang, you are the drawing of the electric motor. It’s all done. I just need to follow the drawings. Most of the credit is on you. I don’t dare to take credit for it!"

"Hey! Our professor of University of Mexico is so humble~!"

Li Zexuan couldn't help but smile.

Yan Shaoning on the side is dissatisfied, "Huh~? Shan Chang, there is my credit in this electric motor! Why are you all neglecting me?"

Li Zexuan waved his hand and said, "Yes! All the credit! When the motor is ready, I will give you a good thing!"

Yan Shaoning was immediately happy, and was about to ask Li Zexuan what good things he would give them. Suddenly Song Xiaosi's voice came from outside the door: "Master Yan, the servant of Yan's house came to send a letter and said It is Yan Shangshu who made you go home today!"

Yan Shaoning was taken aback for a moment. He opened the door of the laboratory, looked at Song Xiaosi and asked: "Little Si, my father asked me to go back? Then can he say why?"

Song Xiaosi saw Li Zexuan still in the room, he first saluted Li Zexuan, and then replied: "Master Yan, this little fourth is not clear, the servant of your house looks very anxious, you want Don't go out and see?"

When Yan Shaoning heard this, he subconsciously thought that something was really wrong with the Yan family. He quickly turned his head and said: "Shanchang, Weier, then I will go home first today~!"

Mo Lingwei waved her hand and said: "Yeah! Go!"

Li Zexuan also nodded, and in his heart he secretly guessed that the words he said to Yan Lide yesterday had worked, and that the old Yan family was about to propose to the Mo family!

After speaking, Yan Shaoning hurriedly walked out of the laboratory.

"Oh! By the way! Shan Chang! There seems to be something wrong with Mr. Wang, would you like to go over and check~?"

After Yan Shaoning left, Mo Lingwei was silent for a moment, then suddenly spoke.

Li Zexuan was taken aback for a moment, and wondered: "Mr. Wang? What's wrong with him?"

Mo Lingwei replied: "Did you not ask Mr. Wang to set up a workshop for electrolytic refined copper before, Shan Chang, but later Mr. Wang realized that the electricity from our hydropower station is alternating current, while electrolytic refined copper requires direct current. If the electrolysis workshop wants to operate normally, it can only pass through the lead storage battery that you made earlier!

But the lead battery needs to be charged after it runs out. It must also be charged with direct current. So, the problem lies here, we must get a sustainable direct current! "

"That's it!"

When Li Zexuan heard this, he couldn't help but suddenly realized that he only made batteries, but ignored the problem of battery charging. When the battery is discharged, chemical energy is converted into electrical energy, and when it is charged, electrical energy is converted into chemical energy. The electric energy mentioned here is direct current, not alternating current. In the previous life, the charger of the lead-acid battery rectified the alternating current into direct current and stabilized the voltage. Now, he does not have a ready-made charger around him. !

"Yes! Shanchang! This problem must be solved as soon as possible! Otherwise, our electrolysis workshop will be difficult to move!"

At this moment, Wang Ji's voice suddenly came from outside the door.

It was Wang Ji who heard that Li Zexuan had come to the workshop. He hurriedly came to Li Zexuan for help. As soon as he arrived at the door, he heard Mo Lingwei tell Li Zexuan about the problems he was facing now, so he couldn't help but push Entered the door and said.

"Heh! Mr. Wang, you are here too!"

Li Zexuan came back to his senses and greeted Wang Ji.

"Well! Wang heard that the mountain leader is here~IndoMTL.com~ and found it! Mountain leader, can you solve the problem of direct current?"

Wang Ji nodded, and then cut to the topic with an urgent expression.

Mo Lingwei also turned his attention to Li Zexuan. In her impression, it seemed that there was nothing that Li Zexuan could do.

Li Zexuan condensed his brows, pondered for a moment, and said: "There are two ways to solve this problem! One is to build a DC generator to directly convert water power into DC electricity, and then connect it to the workshop's electrolysis workshop. !"

"DC generator? Shanchang, why is there a DC generator? Can this thing be made?"

Mo Lingwei couldn't help being surprised when she heard it.

"Of course it can be made!"

Li Zexuan smiled slightly. He took a pen and paper from the table next to him, and while writing and drawing, he explained:

"The reason why the alternating current is transmitted from the alternator is mainly because its rotor windings are rotating and cutting the magnetic lines of force. Whenever a space angle of 180 degrees is passed, the direction of current in the windings will change in the opposite direction. That is, it changes twice a week. This changed current is drawn through the slip ring and the carbon brush. Since the changing law is sinusoidal, it emits sinusoidal alternating current.

When we disconnect the slip ring of the generator and insulate each other, when the rotor winding rotates and cuts the magnetic field lines, every time the space angle of 180 degrees passes, the direction of the current output by the winding will make One end of the output is always positive, and the other end is always negative. In this way, the output is DC! "

After speaking, the white paper has revealed the internal core structure of the DC generator. After looking at it for a while, Mo Lingwei nodded and said: "I understand! Shan Chang, your design is really clever! Oh! By the way, Shan Chang, you just said that there are two ways, but what else is there?"
