Chapter 665: The Triple Definition of Morning Star (Please vote and subscribe)
Luo Chong took his wife and children to take a boat ride, but the boat did not start, so it stayed at the dock. The child was too young, and he was worried about running around in the lake. In addition, the lighthouse construction project in Weishan County has reached the final installation and debugging process, and there is hope that the lighthouse will be lit tonight, so he must be here.
The family stood on the side of the deck. Little Luo Cheng rode on Luo Chong's neck, facing the direction of the lighthouse and laughing. It was the first time for him to play like this. When he was with his mother, he didn't have the opportunity to ride on his neck.
"Husband, the round house up there is so bright." Zhan Ying said while holding the sleeping Luo Lan and looking at the glass house on the top of the lighthouse that reflected the sun.
"That's the glass house. All the walls including the windows and doors are made of glass. Since curved glass is difficult to manufacture, flat glass is used. The entire lighting room is composed of sixteen glass walls of the same size, which are approximately a circle. The doorposts, wall pillars and the grids on top are forged with steel and then painted white. The whole room is transparent, and the light inside can shine directly in all directions. It won't be long before our new house will be equipped with such doors and windows. I'll take you upstairs to have a look after lunch." Luo Chong took his son off his neck and introduced.
The two women were very excited after hearing this, and felt that the Han tribe was getting better and better. Luo Chong was also very excited. He was filled with a sense of accomplishment because all these things were made under his leadership. Although the things in front of him were not quite the same as his design drawings
, he had to admit his mistake this time. The design Luo Chong drew was indeed a 20-meter lighthouse. As a result, he handed the construction of the tower directly to the people below, and he led people to tackle the key equipment inside. As a result, when he came back, he saw that the group of workers had built the tower 20 meters high. Well, the glass house could only be stacked up, so in the final product, the entire tower body plus the more than four-meter-high glass house on top, plus the four-wing windmill on the top of the tower, the height was close to 30 meters. The difference between this and the drawings was also unparalleled, which made Luo Chong very speechless. Fortunately, this result did not affect the use, it was just a little higher.
"Husband, what is that pointy thing on top?" Xiaodie did not understand the construction inside, and only asked questions about those who did not understand.
"That is an iron needle, also called a lightning rod. Because the lighthouse is too high, it is easy to be struck by lightning when it thunders, so a lightning-inducing needle must be placed. The lightning rod is connected to a steel bar below, hidden in the wall of the lighthouse, and leads all the way underground. If the lighthouse is struck by lightning, the lightning rod can lead the lightning underground, so the lighthouse will be fine." Luo Chong explained again.
"Husband, you know a lot." Zhan Ying also looked at her like a little fan girl, which made Luo Chong very proud.
At this time, the lighthouse was undergoing the final painting work. The inside and outside of the tower were painted white. The white paint inside was to improve the lighting, otherwise such a building would be too dark inside, and the white paint outside was to make it eye-catching. After all, the lighthouse is originally a landmark building, and of course the more conspicuous the better.
In addition, the side of the lighthouse facing the lake and the side facing the shore were painted with red paint respectively. Luo Chong personally chose a very meaningful name, the 'Morning Star' lighthouse.
Luo Chong gave this name three different meanings. First, it has a special function of guiding the course of ships, just like the morning star that guides lost travelers. Second, from the appearance alone, the light it emits at night is as dazzling as stars. Finally, it is a spiritual symbol.
The Morning Star Lighthouse is the most technologically advanced building in the Han tribe. It is also the first project to use a large number of advanced construction techniques.
It is the first time that flat glass is used in construction. It is also the first time that lightning rods are used. The focusing lens, large blowtorch, calcium carbide gas, metal welding, rubber seals, and wind power machinery inside represent the top technological products of the Han tribe. All of these are placed in one building. It can be said that the Han tribe currently has the top works in metallurgy, physics, chemical engineering, and architecture. It is a well-deserved Morning Star project that leads the Han tribe to develop a scientific and powerful country strategy. Its political significance is far greater than its practical use.
Oh, by the way, there is also a slide technology that has just come out, or called projector technology. This matter has to start from a week ago.
At that time, Luo Chong had already thought of the name of the lighthouse and determined the exterior color of the lighthouse, so he asked the people below to paint it directly and paint the name on the tower.
But he didn't expect that such a small painting task would encounter difficulties. Because the tower is high, the words on it must be large, otherwise how can the people below see it clearly? As a result, after the person in charge actually measured it several times, he found that a word is bigger than a person. How to write such a big word is not easy at all, because people have to stand in front of the person to write, but if you stand too close, it is difficult to grasp the proportion of the word, and you can't even see the skewness. Moreover, the background color is pure white. If you write it wrong, it will be difficult to correct it.
After the person in charge reported this situation, Luo Chong immediately came up with an idea, which is to project the words directly onto the tower, so that all problems can be solved at once. He may not have been able to do projection before, but it became very simple with glass and calcium carbide lamps.
In his previous life, Luo Chong had seen people making billboards when he was a child. At that time, the advertising cloth was not as advanced as it is now. If you needed any pattern or font, you could just design it on the computer and print it out. At that time, the advertising industry generally used projectors to carve characters. You had to work at night. First, you would print out the required characters in the appropriate font on printing paper, then carve them and stick them on the glass plate. At night, you would use a projector to project them onto colored tape. The carver would first trace the projection, then carve the characters and stick them on the bottom plate.
Luo Chong didn't have a projector, but he had a calcium carbide lamp. The brightness of that thing was no problem for the projector's light source, so he directly asked a carpenter to make a box, opened a square hole on the side to insert the glass piece, and this crude and outrageous projector was made.
After the base color of the lighthouse was painted, Luo Chong wrote the words "Morning Star" on a glass sheet in advance at night, inserted it into a wooden box, put a lighted calcium carbide lamp inside, and placed this thing next to the lighthouse. Three large characters taller than a person were immediately reflected on the tower. All the painters and the people who came to join in the fun were shocked.
Damn, this thing can be used like this
. The principle of projection is very simple. It is nothing more than using the relationship between light source and shadow. It's just that the thing looks a little more advanced. In fact, those primitive people are better at it than Luo Chong. They use the natural projection of sunlight or firelight to graffiti and paint on stones or caves. This trick was even played at the beginning of human birth. Putting aside the glass and calcium carbide lamp, projection is really nothing special.
The outline work after projection has been completed long ago. Now the painter is hanging on the rope to fill in the color outside, and he will soon be able to paint a few large characters.
At the main entrance below the lighthouse, people were constantly coming in and out, replenishing calcium carbide and water. The lighthouse is a cylindrical building with seven floors from the bottom to the glass house on the top floor. Each floor below is 3.33 meters high, and the glass house above has a pointed roof, so the floor height is slightly higher.
The interior of the lighthouse is equipped with a spiral staircase against the wall, but that thing is for people to go up and down. The real supply channel is actually in the middle of the lighthouse. A round hole with a diameter of one meter is opened in the center of each floor, so that it can be connected up and down. When supplies or waste dumping are needed, materials can be transported up and down with bamboo baskets or buckets through pulleys and slings. This is much more convenient than loading materials from the spiral staircase. However, in this way, at least two people must be placed in the lighthouse, one up and one down when loading materials.
It’s okay to have two people in a lighthouse. It’s better than being bored alone. At worst, you can get a couple. Anyway, the internal area of the lighthouse is not small, with several floors.
The first floor of the lighthouse is a tool room. There is nothing but a few tools. It looks very empty. It is obviously to make room for replenishment and unloading. The second and third floors of the lighthouse are fuel storage room and fresh water storage room respectively. Since the Morning Star Lighthouse is not a coastal lighthouse, there is no shortage of fresh water, so the third floor was changed to a kitchen and dining room. The fourth floor is a bedroom with office function. The fifth floor is a multi-functional entertainment room, where you can put some of your favorite things, otherwise it will be too boring to stay in the lighthouse all day. The sixth floor is the equipment room. The calcium carbide warehouse and water tank are on this floor. Only one blowtorch can reach the glass room on the top floor through the round hole in the middle.
Outside the glass room on the top floor, there is a circle of terraces with iron guardrails on the edge of the terrace.
The reason for making this circle of terraces is actually for later maintenance and upkeep, such as repairing the windmill on the top, such as scrubbing the outer wall of the glass room. You have to go outside the house for these jobs. If you don’t add this terrace, it will be very inconvenient.
At noon, Luo Chong's family finished lunch and let the two children take a nap. It was not until the evening that all the preparations were completed. Even the rooms on each floor were cleaned. Luo Chong immediately took the whole family into the lighthouse.
It was evening, and the two little guys were full of sleep. Luo Chong held them in his arms, one on the left and one on the right, with their heads resting on Luo Chong's shoulders. They competed with each other in spitting, and Luo Chong's chest was full of saliva.
"Wow, this circular staircase is great. I think it is much better than the straight curved staircase. Husband, can we install such a staircase when we build a new home?" Xiaodie fell in love with the spiral staircase here as soon as she entered the lighthouse, and suggested to Luo Chong excitedly.
"Of course, no problem, let's go upstairs first, you hold the lamp in front, be careful." Luo Chong nodded and said while holding the two children who were arguing with each other.
"Yeah." Xiaodie agreed and immediately went up with the calcium carbide lamp. Luo Chong followed closely behind, and Zhan Ying teased the two children behind Luo Chong.
Everyone visited the glass room on the top floor. Xiaodie and Zhan Ying were immediately amazed by the scenery in front of them. They covered their mouths with one hand and were so excited that they couldn't speak. This was their first time to touch so much glass at close range.
The walls, doors and windows of the whole room were all made of glass inlays. In addition, there were the huge glass lampshade in the middle and the two focusing lenses that were more than one person tall. The whole room was crystal clear, and people couldn't help but feel like they were in a crystal palace.
Seeing such a room full of shiny things, the two children stopped drooling and stretched out their hands to touch this and that. Luo Chong held the two little guys in front of a lens, and the two immediately stretched their hands to the lens. One was desperately taking pictures there, and the other was talking nonsense there. Fortunately, the magnifying glass was thick and strong enough, and the two children didn't have much strength, so they were left alone.
Xiaodie and Zhan Ying moved closer to the glass curtain wall. It was evening and the sky was slowly getting dark, half of it was pitch-black sky and half of it was setting sun. In addition, they were on the tallest building in Weishan County, or in the entire Han tribe. The view they saw was absolutely unique. Looking down from the seventh floor, the cattle and horses on the ground became tiny. They had never seen such a scene before. They could even see the entire Weishan County through the glass and take in the scenery within several kilometers around.
"How about it, beautiful, isn't it? Soon, our family will be able to live in such a house. By then, we will replace all the windows with glass. If you like, you can also build a glass house and greenhouse on the roof, so that you can take the children to bask in the sun in winter."
"Well, husband, just make the decision. We don't know how to use the glass."
"It's getting dark, let's light up the lights."
Luo Chong looked at the sky in the distance through the glass. There was indeed no light, so he nodded, "You two take the children to the bedroom on the fourth floor first, and I will light the lights. Don't come up unless I tell you."
"Why?" Xiaodie asked in confusion.
"First, because this lamp is very big, the light it emits will be very dazzling, I am afraid that you will not be able to adapt to it, and second, because it is an acetylene lamp, I am afraid that if there is an explosion, you will be injured. It is better for me to do this kind of thing." Luo Chong explained.
"Then do you want to change someone else? We won't watch it. Husband, you are the leader of the tribe, you can't get into trouble." Zhan Ying also hurriedly dissuaded.
"It's okay, you guys go down first. I designed this light, and no one is more familiar with it than me. The light will be fine. I'm just afraid that too much acetylene will be sprayed out at the beginning, so I asked you to leave just in case."
"Okay, husband, you have to be careful."
After the two women took the children downstairs, Luo Chong also began the steps to start the lighthouse. Although this thing is simple, there is actually a set of rigorous procedures for operation, otherwise it is easy to cause accidents.
First, open the vents on the top, and then open all the doors and windows of the glass room, so that the air can flow quickly. Even if a large amount of acetylene starts to react and emerges in a while, the fast-flowing air can prevent acetylene from gathering in the house and exploding. It is an important step before ignition.
Then check the six manual valves under the blowtorch. Each valve corresponds to a circle of nozzles, so that they can be lit one circle at a time, instead of turning them all on at once. In that case, the gas output is too large and it is easy to explode during the ignition stage.
