In order to thank Mr. Octopus for his recommendation in Longkong, I have added a special section.

Will update as usual tomorrow

^_^

"In 2003, Baiyantan Hydropower Station underwent technical renovation. I personally participated in the installation and construction of new turbines. So I am familiar with the site. I went to inspect it a few days ago. Although the surrounding natural environment has changed,

But the general hydrological conditions and geological conditions are the same as before...oh, it's 'in the future'...and there are no changes. Of course, there are no dams yet."

"I know that dam is very huge. I'm afraid we can't build it with our current manpower and material resources, right?"

Local Huang Xiaodong raised his hand to speak, and Lin Hanlong nodded in agreement:

"That's right, the dam on the Wenlan River was built in the 1960s... During the national water conservancy overhaul in 1960, the entire county concentrated its efforts and took two years to build it. It is 94 meters long and has a height of

6.5 meters, and the width of the dam top is 1.2 meters. Of course we can't do such a large project now, but we don't need such a large dam."

Lin Hanlong and a group of brothers brought out the drawing board that had been prepared long ago. There were some illustrative drawings on it. It seemed that he often made such introductions.

"The hydropower station we originally planned to build this time has a capacity of 4X100KW and is composed of four 100KW volute axial flow turbine generators. These generators are low-head motors and can work normally as long as there is a height difference of about six meters.

There is a natural dangerous shoal in the Wenlan River at Bairen Cliff, with a natural drop of 5.3 meters. We only need to increase the drop by one meter to ensure that the generator can work."

"And we don't need to install four at the same time at the beginning. As long as one generator can work first, the power will be sufficient. With 100KW power, it can reach the highest industrial voltage of 330V, which can fully meet the working requirements of any electrical appliance on our ship. After that,

With the enrichment of human resources, we will slowly expand the charging stations."

Finally, Lin Hanlong said optimistically. Everyone looked at each other with inquiring eyes. The project team knew about the plan. This time, the main thing was to convince the laymen - because this project will undoubtedly occupy the entire group.

Once the decision is made regarding the vast majority of manpower and material resources, chemistry, iron-making, and even military training may have to be suspended.

"How far is that hydropower station from the county seat? How to solve the power transformation and distribution problem? How many wires do we have on the ship? Can we pull power all the way to the county seat?"

Later, Ling Ning asked a series of questions. This brother obviously knew something about technology, and the questions he asked were all on point.

"The Baiyantan Hydropower Station is about four kilometers away from Lingao County where we are now, and the power transformation and distribution equipment are also installed together. The spare cables we brought this time are quite sufficient... But according to Pang Gong's plan, we don't plan to

Pull the cable to the county seat."

"Yes, there is no point in bringing electricity to Lingao County. We don't want to provide electric lights to the residents here."

Lin Hanlong kicked the ball back to Pang Yu, and the architect who had been prepared stood up and showed everyone on a drawing board the industrial layout plan of Lingao County he had drawn these days.

"The water resources of the Wenlan River can not only be used to generate electricity, but can also be directly utilized - we plan to build some simple water wheel stamping equipment on the riverside. In the future, the entire Baiyantan area will be built into our industrial zone

, all heavy industry, metallurgy, chemical industry... will be solved in this area. In the future, only the necessary living and commercial base will remain in Gaocheng."

"In other words, in addition to the seaside pier, we have to open a base outside?"

Tang Jian asked with some dissatisfaction. As a soldier, he must consider defense issues, and a basic principle of defensive operations is to try not to spread the force.

But Pang Yu’s answer was also very direct:

"There is no other way. If we want to develop, we can't stay in the city - the seaside salt farm is about to start construction, and the farms in Nanhai are also suitable for land... This area is just downwind of Lingao County and the lower reaches of the Wenlan River.

If there is industrial pollution in the future, it will not affect the county and farm areas. In addition, it is relatively close to the dock, and it will be convenient to transport raw materials and energy from the sea in the future. In fact, I estimate that it will become our main living area in the future, because only

Our electricity usage is not restricted there.”

"How much manpower is needed? How long will the entire construction period take?"

Xie Xi asked, taking out a pen and paper to calculate the manpower allocation.

"The initial stage of building dams and digging reservoirs requires as much manpower as possible. After the infrastructure is completed, only a few of us workers will be needed in the installation stage. Originally, we were going to Guangdong to install the machines."

Lin Hanlong responded confidently. At this time, Pang Yu raised his hand again:

"But even after the dam construction is completed, I still need enough manpower to build power station houses and other industrial buildings, which still takes up a lot of resources."

…………

After that, many people asked some miscellaneous questions, which made Pang Yu feel like he was participating in a bidding meeting. Fortunately, in the end, everyone collectively approved the construction plan - so far, the plans seem to have not been completed yet.

Can't pass.

When the first ray of sunshine rose from the sea level in 1630 AD, the people who gathered at the beach to watch the New Year's sunrise cheered in unison, New Year, New Hope!

Everyone spent the entire January of 1630 AD in a busy manner. The construction of a hydropower station naturally became a "key project" for the public, and they enjoyed the treatment of having all needs met with the highest priority. Just like the last ship re-launch project

The treatment is the same.

However, except for Lin Hanlong and the three or four brothers around him, most people here have no intuitive concept about building hydropower stations. Pang Yu is quite worried about this. After all, this is a very technical job, and it is very difficult for a group of rookies to do it.

It's easy to make mistakes, and once a mistake is made...for example, if the wrong circuit is connected and the motor is burned out, they don't have replacement equipment here.

Lin Hanlong was quite prepared for this. In order to boost morale before starting work, he invited everyone to watch a movie. Everyone was quite happy at first. After all, after two months in Ming Dynasty, his personal spiritual life was extremely lacking. There were more than a dozen decks of poker cards on the ship.

The cards have been broken for a long time. Recently, even the educational films shown for local workers can be surrounded by a circle of modern people watching them.

Moreover, Lin Hanlong also said: The film shown to everyone this time is a new film that no one has seen before!

Two hours before the movie started, countless people had gathered in front of and behind the screen. When the music started, the noisy voices suddenly disappeared, and everyone waited in silence. Finally, a line of big words appeared on the screen:

"Construction of small hydropower stations in rural areas"

…………

One hour and twenty minutes later, all the members of the engineering team finally finished watching the educational film, yawning nonstop. They had responsibilities and could not escape, otherwise they would have fled like other irrelevant personnel.

But just as everyone stood up and prepared to leave, Lin Hanlong, a cunning guy, suddenly jumped out and said calmly - don't leave! The previous show was only an instructional film, and a lighter entertainment film will be shown next.

No one cheered, because everyone was asked to keep quiet, so as not to attract Aunt Hu Wen and other girls who had returned to the girls' dormitory to sleep... Basically, this night was quite happy. Especially the dozen or so girls who had gone back to sleep.

The local workers who performed particularly well and were allowed to join the engineering team to participate in this key project - their legs were weak when they returned, and many of them had nosebleeds.

This move really boosted morale, and in the following ten days, everyone faced the arduous work of building dams and dredging ponds without any complaints. The water flow of the Wenlan River was huge, even in the dry season in winter, and the Baiyantan Hydropower Station, which wanted to imitate the modern one, was built on the river.

It is also very unrealistic to build a dam to block the river. But fortunately, the scale of the reservoir required by this small power station is not large. Lin Hanlong and Pang Yu had discussed it in advance: they planned to build a dam on the nearby tributary. One of the tributaries has a natural drop.

The small waterfall of more than five meters can be used just right.

A diversion channel three meters wide and one meter five deep is dug upstream of the waterfall. The water is directed to the reservoir through the diversion canal, and an overflow tank and a water diversion channel are also set up next to it. Under normal circumstances, the water from this tributary will

It rushes to the downstream of the waterfall through a very steep diversion channel, and the generator is set at the bottom of the channel. After being raised and deepened, the water head drop here will reach ten meters, which is enough for the turbine to work normally.

After the closure, the river will basically stop flowing into a small stream. Only when there is too much water upstream, the excess water will flow through the overflow channel to the original river, and then this small waterfall will reappear.

The bricks used for the base of the power station are old city bricks dismantled from the city gate - the bricks from that city are of better quality. The cement is made from several packages of modern products loaded on ships, because the mortar from the brick kilns outside the city is used.

The solidification strength cannot be guaranteed in the water, so we have to use modern goods, but these are the only few bags of cement on the ship, and they will be out of stock after they are used up.

In addition, after special application, reinforced concrete was used to reinforce certain key parts. More than a dozen tons of building material steel bars were previously found in the cargo hold of the ship, but the military team had long decided to keep these high-quality steel for weapons, Pang Yu said

After hearing a lot of good things, I came up with some.

Turbines, generators, speed regulators, automatic voltage and frequency stabilizing devices... as well as supporting water pipes, valves and other things are all finished products carried on the ship. Lin Hanlong and the others carry a relatively sufficient number of spare parts, but it is impossible to obtain replenishment in any case.

of.

"We don't have the materials to do it a second time, so be careful when installing the equipment so as not to ruin the base and equipment!"

Lin Hanlong paid careful attention to every step, and insisted on doing many key things in person, which caused considerable delays in the construction period. However, this caution was completely worth it. So far, everything has gone smoothly, and all equipment has been installed normally.
Chapter completed!
