C position for 12 years, go home to farm
Chapter 78
When Lao Liu agreed, several people in Happy Farm suddenly felt that the feasibility of building a water curtain was much higher.
A few people who are used to living in the city are not very familiar with the cooling methods in the countryside, but Lao Liu still thought of it.From the perspective of improving efficiency: "Actually, there are water curtains specially designed for cooling in the greenhouse. They are made in one piece, with about ten centimeters of water curtain paper in the middle. It is not very beautiful, but the effect is very good."
He Jun became curious about this: "Water curtain paper?"
Old Liu responded.Although he works in a wood factory, there are greenhouses all around him, and he knows a lot about it: "In the past, those who raised pigs also used it, and now there are a few who raise flowers. The greenhouses need to cool down in summer. In addition, there are also people who toss about this."
"The paper in the middle is honeycomb paper, and it will get wet when it absorbs water. It is framed with aluminum alloy around it, and the water will not leak. Then install a negative pressure fan, the hot air will be drawn out, and the cold air will be poured in. The water evaporates and absorbs heat, and the temperature in the greenhouse will suddenly drop." Come down."
The water curtain mentioned by Lao Liu sounds like it can cool down the greenhouse very well, and the production method or material procurement is also very simple.
He Jun thought about it, and immediately thought of the key question: "We are not sealed in the greenhouse. The effect of such a water curtain should not be as good as in the greenhouse?"
They are going to cool down outside, and the effect of using this setup is roughly like having a piece of wet cardboard next to them.It is completely different from the effect that can be achieved in a closed greenhouse.
Lao Liu suddenly said, "That's right. You need to add a fan. It's not as good as an air cooler. I'll ask someone to figure it out."
He Jun responded: "My idea is to use a windmill-like structure to borrow water or force from the river. After the water passes through, we will see how to form a water curtain."
Old Liu Lianlian responded: "I'll think about it, I'll think about it. We have to meet and discuss it."
He Jun: "Okay. I'll come over when I'm free."
The two agreed to hang up the phone.
Lao Liu was thinking of a way, and He Jun was thinking of a way too.
He didn't come from an engineering background, so he really had a lot of ideas. He took a blueprint and drew it up simply: "Just now, when Lao Liu talked about the negative pressure fan, we can actually use the air pressure and the gravity of the water."
He Jun's grades in the culture class are not bad.He drew three facilities with height differences on paper: "To make water go from low to high, we can also use the 'siphon principle'."
The other four people leaned over to look at the drawings.
There are three settings on the drawing, the one in the middle is the shortest, the one on the left is the second, and the one on the right is the highest.On the left is a completely closed container, with some pipes vaguely drawn in the middle, and the tallest one on the right is the device where they will eventually emit water to form a water curtain.
A few people were quick-witted and understood He Jun's meaning: "It seems like you can try it." "You need to buy a plastic pipe for the middle pipe to experiment." "Yes, you have to think about how to circulate the water."
Compared with buying machines, buying a few pipes and containers can save a lot of money.
Considering that the material they need is not one point or two, and they need to borrow from the river, He Jun said: "We have to measure the distance from the river to the farm. The river has to see which point to choose."
The four responded.
The next live split up.Ye Hao and Tong Wenle went to the other side of the river to check out some spots, and measured the distance to this side.Qiu Feng went to the store and asked the boss if he could help to buy some plastic pipes, plastic faucets, etc., and made an appointment in advance.He Jun and Guan Zhengyang went to Lao Liu to discuss the production plan in detail.
Divided into three teams and dispersed, He Jun and Guan Zhengyang rode bicycles to Lao Liu's wood factory.
Since I got bicycles, the speed from Happy Farm to Old Liu Wood Factory has been much faster.He Jun didn't ride for long and arrived at the destination very quickly.
The recent weather has been mostly showers.One second the sky was clear and the sun was scorching hot, and the next second it was suddenly pouring rain, pouring down directly on the person's head.
Not all the wood in the wood factory is waterproof, and all of it has to be moved indoors or placed under a built shed.Now the outside of the wood factory looks like there are not many logs.
He Jun and Guan Zhengyang parked their bicycles under a shed.The two walked in together.
He Jun yelled: "Old Liu, we are here! I will trouble you again today!"
Lao Liu only wore a mask today and no gloves.His hair was wet, it looked like he had just washed his hair at noon, and it was washed for a while when he met someone, and he didn't dry it completely.He poked his head out of the carpentry factory, and when he saw someone waving, he said in a muffled voice with a little joy: "Come on, come on, I just figured out something."
He Jun and Guan Zhengyang hurried over.
Lao Liu set up a table in the wood factory.A bunch of things were arranged in a messy and orderly manner on the table.Messy and orderly are a pair of completely opposite words, but this is how it feels on the table.
The messiness lies in the miscellaneous and many things, and all kinds of things that cannot be named are placed in a pile.Orderliness lies in the separation of small and large items. The handles of the small items are all facing the same side, and the large items are placed in a position where they will not hurt themselves at all.
Among so many things, Lao Liu's notebook is still eye-catching.He rubbed his hands on his clothes, then turned to the latest page, and took a pen to draw a picture for He Jun: "When my son was young, I made him a small windmill, oh no, this one has to be called a waterwheel."
With a few strokes, he drew the waterwheel he made back then on paper.
When He Jun saw the picture, he found that it was different from the windmill he had imagined.
Old Liu said while drawing: "Wind-powered waterwheels use wind power to operate. Traditional waterwheels use water power." The waterwheels on the drawings are purely using water, and no matter what you say, you can't call them windmills.
At first glance, the drawing looks like a thick disc with many wooden boards spliced on it, which looks like a Ferris wheel for people, but it is not exactly the same. Each seat of the Ferris wheel has been replaced with a 45-degree inclined wooden board.
He Jun listened carefully from the side: "We are far away, so the impact should be great. Do we need to build a big water tanker?"
"The river around us is not strong enough. You have to find a place with plenty of water, the closer the better, and we will build another track. Let the water gather and generate a greater flow, so as to impact the waterwheel. Let it Can generate more power."
He Jun suddenly said: "Ah, yes. We don't necessarily have to choose a place with strong water flow."
He quickly sent this news point to his teammates.
Lao Liu and He Jun said: "One is not enough, just two. You don't have to make it too big. The wood is also expensive. You can make one that costs more than buying an outdoor air cooler. Why bother?"
Very reasonable.
Lao Liu drew the central axis: "This whole can be made of wood. To save time, let's not play with mortise and tenon structure, and fix it directly with hardware. It will take some time to make, and the venue is definitely not available at your place. It has to be in front of our factory. Come empty."
The main reason is that there are a lot of large tools needed, and the wood is heavy.It takes a lot of energy to make it, so it is not suitable to waste time elsewhere.
He Jun responded.
As Lao Liu was talking, he suddenly laughed: "This is really ready, you can add something on the side later, grind soy milk, coffee, whatever."
He Jun: "???"
Guan Zhengyang followed in shock: "Ah? Ah? Is this motivation so strong?"
Old Liu proudly: "That's right. I can tell how strong this power is just by looking at it. Your water curtain can be easily filled with this water. There is no need to worry at all."
As soon as the few people finished speaking, Ye Hao and Tong Wenle on the other end replied.
If you don't need to choose a place with extremely strong water flow, then the river is not far behind the happy farm house, and you don't need to choose another place at all.After all, Zhongyu Island is an island in the river.
Tong Wenle took a few photos and sent them over.
He Jun took the mobile phone and asked Lao Liu: "Is this place OK?"
Lao Liu took the phone and looked at the picture, zoomed in and out, and imagined in his mind: "Well, I think it's okay."
He Jun nodded: "Okay, then I'll go back to them."
After replying to the news, He Jun took out the picture he had just drawn in Happy Farm and handed it to Lao Liu: "This is the structure of Shangshui I came up with. I don't know if it can be done."
Lao Liu glanced at it, realized what He Jun wanted to do, and drew a more detailed water curtain structure for He Jun on the spot: "It depends on how tall and big the water curtain you want to make. If it is small, use a water curtain. If the pipe is large, you can consider feeding water on both sides. Make a water distribution pipe on the top and a reservoir on the bottom. Fish can also be raised in the reservoir.”
It's very interesting!
He Jun was in high spirits, and discussed along the sidelines: "We want the sound to be quieter. Do we need to add something for sound insulation inside? Or can the water flow be controlled to a certain size, so that the sound will naturally be quieter?"
Lao Liu didn't think about this detail: "There are sound-proof sponges for the decoration, you can try it when the time comes."
Guan Zhengyang added a suggestion on the side: "Can you add music? Add lights. It's the same as the one on the square, with music and a disco water curtain, cool!"
Lao Liu felt that there was no conflict at all: "Yes."
Guan Zhengyang leaned over and squeezed Lao Liu's shoulders on the spot: "Master, you are so capable. Let me tell you, you just lack an opportunity. This thing can completely apply for a patent as a whole, and it will definitely sell for money later."
Old Liu was a little at a loss when he was pinched by a young man outsider.Seeing that He Jun smiled naturally, he quickly relaxed unconsciously: "Hey, someone must have applied for a patent for this kind of thing long ago. Otherwise, how did those water curtains that have already been made come out?"
Guan Zhengyang retorted: "Those are all powered by electricity, but yours is hydraulic, which is different. In the future, the patent can be sold to the company to make money. Patents don't have to be high-tech."
He Jun agreed from the side: "Yes. Our group messed with some small things before and applied for a patent."
Old Liu: "?"
Lao Liu did not expect that some men's groups can sing and dance and even apply for patents.He couldn't help asking curiously: "What patent did you apply for?"
When He Jun mentioned this incident, he had to warn in advance: "Then, Lao Liu, you can't laugh when I say it."
Lao Liu nodded.
Lao Liu hadn't laughed yet, but Guan Zhengyang began to "poof" when he recalled the funny things like "invention patents" back then.
He Jun said with a smile: "There are five people in our group, and the number of people playing the seesaw is uneven. The weight of a two-person seesaw cannot be balanced. So we developed a... a seesaw with springs."
Old Liu: "?"
He Jun: "When I was writing, the pen ran out of ink, and I wrote with a refill that was a bit broken. I don't know what to do when I turn around, but I finally successfully applied for a patent anyway."
Old Liu: "?"
Is this how science and technology develop?
A few people who are used to living in the city are not very familiar with the cooling methods in the countryside, but Lao Liu still thought of it.From the perspective of improving efficiency: "Actually, there are water curtains specially designed for cooling in the greenhouse.
