Development of productivity started in 1981

Chapter 54 Base Construction (asking for monthly tickets and recommendation tickets)
According to the drawings designed with the help of Tomoko, this elevator has an extra-large cabin that is 2.8 meters long, 2.2 meters wide, and 2.5 meters high. Such a large cabin can transport very large objects.

Therefore, the motor, cable and base on the top should also be designed to be thicker and stronger.

Because the interior of the mountain is rock, it is sufficient to use super powers to embed both ends of the cable system more than 3 meters into the rock.

A total of 5 groups of 10 cables are used as the lifting ropes of the car, one group at each corner and the middle. Each group is designed with a synchronization device to ensure balance.

The electric motor that powers the cable system is a giant with a diameter of half a meter and a length of 1.2 meters. It weighs more than 800 kilograms and uses half a ton of copper.

The car frame is made of high-strength alloy steel, and the car wall is made of corrosion-resistant galvanized iron.

It’s not that we don’t want to use stainless steel, but there is a shortage of nickel in Dexing, and the nickel production area is quite far away from Jiang Province, so we can’t find a way to buy it for the time being.

Perhaps once the trade routes are opened, we can import some from Southeast Asia, where there is more nickel and it is cheaper than in China.

The cabin is built underground. The bottom of the cabin is a 3-meter-deep pit with a raised support base.

The cable had not been manufactured at this time, so we first tested the top motor and the cable system connected to the motor. After running for a few minutes, we found that there was no problem and the synchronization was also very good.

So they began to mobilize elements such as iron, manganese, copper, aluminum, and carbon to make cables.

With the help of Wang Jiankun's super powers, 10 cables grew downwards from 10 fixed holes on the top.

There was a lighting lamp temporarily installed by Wang Jiankun in the vertical shaft. The cable swam underground like a python under the dim light until it connected to the 10 connection holes of the car.

It is very exhausting to control 10 cables at the same time and keep multiple elements in a certain position.

However, this is beneficial to Wang Jiankun's fine control and multi-threaded operation. After completing the cable manufacturing, Wang Jiankun tested the projection distance. At this time, he could project and control objects within 80 meters from the body.

After resting for a while, he checked the cables and connecting points that he had just made with his superpowers to make sure that they were all manufactured according to the drawings.

Wang Jiankun began to manufacture slides and gear fall prevention systems in elevator shafts.

There was no showing off this time. The 6 slides and 3 sets of gear systems were manufactured one by one in sequence.

After manufacturing is completed, it can be tested. First, turn on the power supply. The small light inside the button next to the elevator at the entrance of the passage will light up, indicating that the circuit is connected.

I pressed the button with the number 3, and the elevator started and went up to the third underground floor.

Using super powers, I observed that the elevator opened its door after stopping on the third floor, closed the door after waiting for 10 seconds, and then went back to the fourth floor and stopped after waiting for another 5 seconds because no other signals were received. This shows that the elevator is operating according to the set program.

Because the second and first floors have not been excavated yet, only the position of the elevator door has been reserved, so the first and second floors will not be tested.

He pressed the * at the top of the panel, and the elevator started and came to the entrance. After the door opened, Wang Jiankun walked in.

In order to save electricity, there is only a 10-watt light bulb inside. Press the button for the 4th floor inside the elevator, and the elevator slowly closes and then starts to go down.

Because it is mainly used for freight and the entire height is not very high, the elevator speed is controlled at 1 meter per second, and it takes exactly 1 minute from starting to the fourth floor.

Although the underground had been dug for more than 10 days, it was the first time that Wang Jiankun set foot here.

The ground inside is simply hardened, and the circular wall is paved with a thin layer of aluminum alloy. Wire mesh and steel plates are used to fix the rocks above to prevent small gravel from falling.

There are only three small lights above my head. I press the switch next to the elevator to turn on the lights and I can see that it is still very empty.

The circular space is supported by six rock pillars with a diameter of 6 centimeters. This was calculated by Zhizi to be enough to support the floor above.

Wang Jiankun walked along the side wall and used his superpowers to project the places he explored into his mind. He found no valuable minerals, only the same rocks as the mountain.

Because only a very small ventilation duct was dug, the air quality on the 4th underground floor was still relatively poor. I felt a bit stuffy after staying there for a while, so I quickly took the elevator upstairs.

It seems that the ventilation system cannot be simplified. Two sets of ventilation systems should be excavated independently for each floor, and then integrated during construction.

Having used up his superpowers for the day, Wang Jiankun pulled the double cart into the passage for storage, and carried the motorcycle through the passage to the rented house.

Building the elevator and moving things took up a lot of energy and physical strength. I stopped listening to shortwave information at night and went to bed after washing up.

------

When I got up in the morning and fetched water to brush my teeth and wash my face, I felt that the water suddenly became much colder. There was a layer of white frost on the courtyard walls and trees.

I recalled the lunar calendar solar terms and found out that yesterday was the first day of the Frost Descent solar term. There was no dew this morning and it all turned into white frost.

After washing my face with cold water, I instantly woke up and rode my motorcycle to school, breathing heavily.

After arriving at the classroom, Fang Guihua collected the test papers and handed them to him. He planned to review them before the morning class. As usual, the morning reading was to read aloud the English text.

Now Wang Jiankun can switch freely between London accent and New York accent. After all, he listens to English radio every once in a while and often hears the bragging and nonsense of "hams". He can also understand and imitate some slang jokes.

In the past week, the English teacher likes to ask him to answer questions in class, and asks questions in English and asks Wang Jiankun to answer in English.

Some students with poor English grades were confused when they saw the two people speaking English to each other, and only those with average or above average grades could barely understand.

For this reason, the English teacher often used Wang Jiankun as an example and asked everyone to learn from him, which caused some students to look at him with some unfriendly eyes.

Wang Jiankun has already promised his English teacher to help him get some English listening tapes. The English teacher has also applied to the school for a tape player, but is still waiting for funding.

Wang Jiankun decided to ask his uncle to buy the listening tapes in Guangzhou and send them to him. The English education in Guangzhou is relatively advanced and formal. He saw English tapes for sale when he went to the library last time.

In the morning class, Wang Jiankun first asked Zhizi to help correct and analyze the test papers of three classmates and evaluate their learning abilities.

Fang Guihua has the best learning speed and knowledge mastery, followed by Hu Chunming, and Cheng Ming is the worst. However, with Zhizi's intelligent analysis and targeted filling of gaps, they can still keep up with the progress.

Judging from the test papers of the past two weeks, the three of them will be able to improve a lot by the time of the midterm exam, but of course, they cannot be ruled out from not performing well on the spot.

Let Chieko make a study outline for the three of them and list the key points and difficulties, and also make a set of test papers for each of them, and give them to them when they come for dinner tomorrow.

After lunch in the cafeteria on Saturday, I went to the message room and saw a telegram from my uncle and another from Peter's agent in Dexing.

My uncle's telegram described his conversation with Peter. Peter agreed to help collect it, but said it was difficult to buy in Hong Kong.

Only a few universities in Hong Kong and some laboratories of multinational companies in Hong Kong subscribe to this professional journal.

He has to ask his family in the United States to help buy it and then send it over, which may take half a month. Helium transportation is more troublesome, and it may take one and a half months to reach Guangzhou Customs.

At the end of the telegram, my uncle asked if we could wait. He planned to go to the university in Guangzhou to see if there were any that subscribed to this type of journal. If there were, he would make a copy and send it to Wang Jiankun.

Peter's agent in Dexing was the translator he had met before, named Xue Wenqing. The telegram he sent said that he wanted to order the same number of lighters as last time, a total of 2.4, and asked Wang Jiankun to reply to him as soon as possible.

I looked at the time and found that there was still time to send a telegram and make a phone call, so I trotted to the post office not far away.

First, I sent a telegram to my uncle and told him to reply to Peter and ask him to collect as many as possible and send them back one by one. If he can find them in the university in Guangzhou, please help make copies and send them back. It doesn't matter even if they are duplicates of what Peter bought later. The time for helium to arrive is acceptable.

Then he called Peter's agent Xue Wenqing, who happened to be back in the office when he called. The two discussed on the phone and decided to deliver the goods next Sunday. Before the delivery, Wang Jiankun went to Dexing Post Office to call Hong Kong to confirm the payment.

Goods will be delivered only when payment has been received. If not, they will be stored in Dexing’s warehouse first. We will then wait one week before going to Dexing to confirm the receipt.

Doing international trade is troublesome at present, especially for people like Wang Jiankun who want to retain foreign exchange.

In fact, even transactions through import and export companies are very troublesome. After all, the reform and opening up had just begun, and we had little experience in dealing with foreign companies, especially European and American companies.

After making the call, I quickly ran back to the classroom to attend class. Even though I didn't have to attend the lecture, I still had to go.

Wang Jiankun plans to apply to the school after the midterm exam next week to allow him to skip classes if he has something to do, and then submit a leave application later.

In the afternoon class, Wang Jiankun took out the NS equation problem to kill time. At present, he had no idea. Wang Jiankun had never really done mathematical research. He completely relied on the supercomputing analysis capabilities of Youzhizi to assist him.

But he hasn't discovered this yet, which has both advantages and disadvantages.

He found that there was no way to solve the problem directly, so he thought of deriving some basic theorems and formulas first to see how other mathematicians studied mathematical problems.

He was essentially preparing to walk the path his predecessors had taken again, which laid a solid foundation for him to conduct more in-depth research in the future.

After class in the afternoon, Wang Jiankun went to the waste recycling station and checked the accounts and recycled items with Ye Wei and his wife. After finding no mistakes, he let the two go home.

Wang Jiankun has installed alarm devices on the iron door and the back door here. If they are not unlocked but opened violently, drugs will be sprayed out to instantly knock out people within a 2-meter range, and a signal will also be sent to Wang Jiankun.

So there is no need to have anyone guarding the place all the time. Wang Jiankun told Ye Wei and his wife not to come on Saturday and Sunday nights.

This also made it convenient for Wang Jiankun to transport supplies. During this period, Ye Wei also asked why there were sometimes more and sometimes fewer boxes.

Wang Jiankun told him not to worry about the boxes, just be responsible for the recycling business and keep an eye on the gate.

Seeing that Wang Jiankun refused to explain in detail, Ye Wei stopped asking. He sensed that Wang Jiankun was unhappy.

Such an easy job is not easy to find, and now his wife can come to accompany him. As she becomes more and more skilled in making cotton cores, his wife can now earn about 1 yuan a day, and her salary is almost the same as his.

The two of them can now earn about 10 yuan in October, which has greatly improved the family's life.

I was thinking of renovating my house after the Chinese New Year. I don’t plan on building a big one, but a two-story, two-room brick house should be fine.

Not to mention the happy fantasies of Ye Wei and his wife, tonight he transported a total of 3 tons of metal to the underground base in two trips as usual.

He has a lot of tasks to do tonight. First, he has to add another ventilation pipe to speed up the ventilation. Another thing is to build a diesel generator and energy storage equipment.

I tested the elevator last night and turned on some more lights. The electricity meter in the rental house started whirring. I checked in the morning and found that it had used 12 kWh of electricity.

If you go in and out of the elevator every day and turn on the lighting and ventilation equipment, you will use more than 3 kWh and almost 4 kWh of electricity in a month.

The electricity consumption at the Two Sessions is very eye-catching. There are residential houses all around, and the average family only uses 3 to 4 kWh of electricity. Those with better conditions and more electrical appliances only use 5 to 6 kWh at most.

He didn't want to steal electricity, so before the miniature nuclear reactor was successfully built, the underground base would first use diesel generators.

It is relatively cheap to buy diesel now. There are few fuel-consuming equipment in the country, and China is still an oil exporter.

No one will come to check what you have been doing if you buy more oil. Besides, there are three trucks and my father often goes there to fill up diesel, so there is no need to worry about the people at the gas station suspecting anything.

It doesn't take much effort to dig the ventilation duct. Use superpowers to extract the elements at the selected location one by one. The three elements of aluminum, magnesium and iron are used nearby to reinforce the pipe wall. The water vapor is first allowed to flow to a temporary water storage tank on the fourth floor.

A fan was installed at the exit on the mountainside and camouflaged, ensuring that the terrain of the exit was the same as the surrounding environment.

I connected the fan to the power cord, turned on the switch and tested it. The ventilation effect was very good, which was completely sufficient for the 4th floor. The air in the elevator was also much better.

After the temporary ventilation system is completed, a power transmission, transformation and storage system must be built first.

There needs to be a transformer. The voltage of the diesel engine is currently only set to two levels: 400 volts and 230 volts.

The equipment used in the future may have several voltage and current requirements, so transformers and power transmission and transformation systems are necessary, and energy storage systems are also necessary. Otherwise, if there is excess electricity generated and it is not used, it will only generate heat and dissipate.

The transformer is very simple. Wang Jiankun had both physical objects and data for reference, and he drew it out very quickly according to the drawings in his mind.

We thought of several energy storage systems during the day, and then drew up three plans for Zhizi to simulate. Finally, we decided to use the most mature lead-acid battery. Although the unit energy storage density is small, compared with the lithium carbonate battery currently available in the information, the lithium iron phosphate battery is much safer.

I built a lead-acid battery array with a maximum storage capacity of 400 kWh of electricity, connected it to a transformer and charging and discharging circuits, and tested it using electricity from the rented house. After testing the charging and finding no problems, I disconnected the power supply and waited until the diesel engine was built before conducting joint debugging.

The diesel generator equipment was also designed by Zhizi a few days ago, with reference to Yuchai's 200KW diesel engine.

On this basis, optimization was made. According to Wang Jiankun's precision control requirements, the design index of precision parts such as bearings, cylinder pistons, etc. was 0.05 mm, which is 0.2 times the precision design of 4 mm of Yuchai's machine.

According to the drawings in my mind, I first used my superpowers to directly generate the load-bearing base and the outer shell, and then checked whether the dimensions met the requirements of the drawings. Only after confirming that there were no problems did I proceed with the manufacture of the internal precision components.

Generate the cylinders, pistons, crankshafts, gears, bearings, rotors, stators, etc. one by one inside, and then generate and connect the corresponding pipes, valves, lines, etc. one by one.

Then check the whole thing against the drawing in your mind to make sure there are no omissions, no dimensional errors, and no abnormal points. Then add the lubricating oil and diesel purchased in advance, and then add the water collected just now to the water tank for cooling.

After the generator is built, it is time to prepare for testing. It is already past 9 o'clock in the evening, and there should be no sound from the test at 50 meters underground.

For safety reasons, a layer of sound-absorbing material was created on the walls, floor and ceiling surrounding the fourth-floor space (referring to the sound-absorbing material in the auditorium).

Then he checked the circuit and turned on the switch of the diesel generator. The diesel engine started up with a roar. Wang Jiankun, who was nearby, thought the sound was very loud.

Wang Jiankun, who was worried, kept the diesel engine running at the lowest power, and he took the elevator to the entrance to listen to see if he could hear any noise.

In fact, when the elevator reached the third floor, Wang Jiankun could only hear a faint sound, but he could not hear it at all at the top entrance.

After walking out of the passage and listening in the valley and the room, Wang Jiankun found no vibration or sound, so he returned underground with peace of mind.

In fact, the noise of the diesel engine is much quieter when you stand a few meters away. The sound-absorbing material used by Wang Jiankun is very solid, so it is too cautious to worry that it can be heard outside.

Gradually increase the power, the oil inlet and air inlet open larger and larger as the power adjustment handle is turned. When the pointer of the power meter reaches 200, Wang Jiankun fixes the handle and lets it run stably for 10 minutes.

At this time, except for a small light on the test circuit, all other electricity was input into the energy storage system. Seeing that the charging indicator light and the instrument panel were in normal status, Wang Jiankun felt relieved.

After running for 10 minutes, I found that there was no problem. Then I pushed the handle to the maximum designed value. The sound of the generator also became a little louder, but not very obvious.

At this time, the pointer of the power meter reached the design parameter of 220KW. After letting it run for another 10 minutes without finding any problems, Wang Jiankun adjusted the power to the main power of 200KW.

Half an hour later, the diesel ran out and the generator automatically shut down. I used my superpowers to check the generator and found that the wear levels of its internal moving parts were within the design indicators. At this point, the base's electricity problem was preliminarily solved.

Connect all the lights, ventilation systems, elevators, etc. in the base to the newly built integrated power generation and energy storage system, so that the electricity meters of the rented houses will not be abnormal.

The next thing to do is to excavate the top three floors with all our strength, and at the same time manufacture some production equipment in the base, and then carry out trial production. After the operation tests are completed and there are no problems, they can be shipped out and provided to the corresponding factories.
