In addition, there is no transmission device inside the bladeless wind turbine, such as gears and connecting rods.

In wind turbines, it is these constantly running transmissions that are prone to wear and tear and increase maintenance costs in the later period.

At the same time, under extremely cold conditions, these precise transmissions are more susceptible to damage from the cold, resulting in machine failure.

The transmission device is canceled, the probability of loss is reduced, the cost of later maintenance is reduced, and the cost is also reduced.

more importantly......

This bladeless wind turbine solves one of the biggest problems...

The anti-freezing design of the transmission device and blades.

If it is an ordinary bladed wind turbine, then engineers need to consider the design of the antifreeze system.

In extremely cold conditions, the blades and transmission devices cannot freeze. Once frozen, they cannot rotate and cannot generate electricity.

The bladeless wind turbine directly cancels the blades and the transmission device. The reduction of these two key parts will greatly reduce the amount of design for engineers.

Xu Qiu nodded slightly.

The bladeless wind turbine is indeed a very thoughtful design idea.

And, there is one more detail that deserves appreciation.

The wind column of this bladeless wind turbine is elastic, which can make the conversion of vibration energy into electrical energy more efficient.

"but......"

"The bladeless wind turbine has a disadvantage. After the sun goes out, the continuous wind on the surface will cause the equipment to twist and move."

"Especially the lower part of the elastic rod needs to withstand greater external force and is more prone to damage."

Xu Qiu shook his head, this is a difficult problem to solve at present.

Unless a very strong material is developed that can withstand extreme cold, bladeless wind turbines will not be able to gain a foothold on the windy surface.

He continued to scroll down, his eyes suddenly lit up.

《Anti-icing and high wind system under extremely cold conditions. "

Lu Guangyuan explained: "Director Xu, this was developed by Xu Wenxing from the Northwest Energy Bureau. He has been working on the development and operation of wind turbines under cold conditions. Therefore, after the start of the Wind Dragon Project, he has been researching This thing, just gave this theory today.”

"As for whether it works, it still needs to be approved by you."

Xu Qiu was a little surprised. He never expected that the people from the Energy Bureau would be able to provide an anti-icing system so quickly.

He carefully browsed through Xu Wenxing's design.

Under extremely cold conditions, wind turbines cannot operate normally. The biggest reason is that the generators and blades are icing.

In this anti-icing system, an electric heating element is embedded in each blade, and it is equipped with an icing degree sensor feedback device and other temperature sensors to monitor the status of the blade at any time.

Moreover, according to the thickness of the icing coating, the operating efficiency of the electric heating element is adjusted to ensure no icing.

Xu Qiu shook his head.

Relying on electric heating to prevent freezing is only a temporary solution, not a permanent cure.

The efficiency of converting wind energy into electrical energy is not high. If a part of the energy is used to activate the entire wind turbine for heating, the already low energy conversion efficiency will be pitifully small.

However, this anti-icing system still has merits. At least, it can allow wind turbines to continue to be used in extremely cold conditions and can indeed generate electricity.

However, this can only be used as a last resort.

Xu Qiu continued to read.

There are indeed quite a few wind turbine plans, design drawings, and conjectures provided by the Energy Bureau.

For example, in addition to the bladeless wind turbine designed with elastic wind columns using aerodynamic effects,

There is another bladeless generator, which is also worth seeing.

This bladeless wind turbine is based on the vortex bladeless concept.

The wind turbine has a three-and-a-half-meter triangular-shaped antenna tower core, from which a three-meter-long, ten-millimeter-diameter aircraft cable is suspended.

Inside, there's also an electronic control unit running the stepper motors that control the tension in the cables, similar to the tuning of guitar strings.

The central cable of the bladeless wind turbine passes through the free-floating magnetic oscillator core.

The main part of the bladeless wind turbine is a glass fiber or carbon fiber outer tube with a diameter of [-] mm and a length of [-] meters, with a built-in free-floating core, which collects the available wind force of a large cross-section with the help of aircraft cables and oscillator cores. .

To put it simply, these designs all have merits, but there is still a long way to go to impress Xu Qiu.

"Not bold enough."

For the proposal submitted, Xu Qiu only gave this evaluation.

People in the Energy Bureau are too official, too standard, and too disciplined!

However, in the extremely cold era, thinking according to the inherent thinking will only lead to a dead end!

Hearing Xu Qiu's comment, Lu Guangyuan already understood most of it in his heart.

Like the development of extremely cold steel rails and cold concrete,

These engineers indeed represent the highest wisdom of the Dragon Kingdom, and even the whole world.

However, it is precisely because they are too grounded in reality and obsessed with various design difficulties and construction difficulties that their imagination is limited.

Xu Qiu said: "Dragon Kingdom is full of talents, and there will always be someone who can come up with unconstrained ideas. Let's solicit proposals from the whole country."

"Try to find out the prototype of this wind turbine before the Little Ice Age, and keep improving it until it can stand on the surface of the extremely cold era!"

Lu Guangyuan said respectfully: "I obey, Director Xu!"

After half an hour.

The Dragon Country Strategic Crisis Bureau and the Dragon Country Energy Bureau released the news at the same time.

[Dragon Kingdom Strategic Crisis Bureau: Starting today, the Wind Dragon Project will be officially launched.This is an important plan for energy storage and supply in the extremely cold era of the Dragon Kingdom. Please cooperate with all parties to coordinate the construction of the underground city and carry it out together. 】

[Longguo Energy Bureau: Our bureau has received special instructions from the Emergency Bureau.From now on, our bureau will make every effort to develop extreme cold wind turbines.On the same day, our bureau solicited plans and ideas from talents all over the country. Once adopted, they will be directly rewarded by our bureau and the crisis bureau! 】

When the news was released, the whole people was boiling.

"Damn it, Wind Dragon Project! This sounds too cool!!"

"As far as I know, only a small number of areas in the northwest and northeast of Longguo have a wind energy utilization plan, and the sharpness of the rest of the area cannot meet the requirements. Our country has to start this plan. Does it mean that in the era of extreme cold, the wind power will be become an important resource?"

"Absolutely, the emergency situation bureau has made it clear that this is an important plan for international abnormal energy storage and supply in the extremely cold era! After the sun goes out, solar energy will no longer exist. At that time, wind energy may become the most common clean energy !”

"Could it be that there will be ubiquitous gusts of wind on the surface for us to collect?"

"This is too difficult! One thing I know is that most cold-resistant machinery will be damaged at minus one hundred degrees, and in the era of extreme cold, the temperature on the surface will drop to minus more than 200 degrees!

Wind turbines are originally precision instruments, and the components inside are likely to be damaged. How can it be possible to ensure the operation of wind turbines under extreme cold! "

"Hahahaha, we didn't catch up with the national solicitation proposal for the dungeon last time. This time, the wind turbine has started a nationwide solicitation. We must contribute!"

"Yes, the direct rewards from the Energy Bureau and the Crisis Bureau are not important. The main thing is to contribute to our country's energy industry and contribute to the construction of disaster prevention facilities in Longguo!"

Du Niang, post about wind turbines.

After the Longguo Crisis Bureau and the Energy Bureau issued a statement at the same time, this niche post bar became lively in an instant.

A large number of netizens poured in, wanting to see if these fans have any valuable ideas.

A man with the same style as the master, published a popular science post.

【A man like the wind】:

"Hello everyone, I am the owner of the wind turbine bar, and I am also an engineer working for the Energy Bureau of Northwest Gansu Province. I have participated in the development of various wind turbines."

"Presumably everyone is very curious about the extremely cold wind turbines in the statement of the Emergency Management Bureau and the Energy Bureau."

"Many people even want to come to the post bar to see if the master of the post bar has any good ideas, and even want to get some rewards from crisis situations..."

"Using this opportunity, I would like to share with you the structure of wind turbines and... how difficult it is to get this reward!"

"The wind turbines we generally talk about are usually composed of wind rotors, wind-facing devices, speed control devices, transmission devices, generators, towers, parking mechanisms, etc."

"The more common one is the horizontal axis lift type wind turbine."

"The wind rotor is the most important part of the wind turbine. It is the main symbol that distinguishes the wind turbine from other power machines. Its function is to capture and absorb wind energy, convert the wind energy into mechanical energy, and transfer the energy to the transmission device through the wind rotor shaft. .”

"The composition of a wind wheel includes blades, petioles, hubs, and wind wheel shafts."

"If you want to operate in extreme cold, the most critical step is to ensure that the wind wheel can withstand the environment of minus two hundred degrees and will not freeze."

"Therefore, we need to design the arctic blade, arctic petiole, arctic hub and arctic wind hub..."

"Is it hard enough? But it's more than that!"

"Among the components at the upper end of the wind turbine tower, the wind rotor, transmission device, wind-facing device, speed control device, generator, etc. constitute the nose, and the connecting parts between the nose and the tower are the nose base and the gyratory body."

"Leaving aside the nose, its importance is self-evident."

"The nose seat is used to support all the devices and accessories above the tower. Whether it is firm or not will directly affect the safety and life of the phoenix machine."

"Due to the light weight of the equipment above the tower, small wind turbines are generally composed of base plates re-welded to strengthen ribs."

"The headstock of medium and large force machines is more complicated. It is usually welded by longitudinal beams and beams, supplemented by platens, webs, ribs, etc. and has higher requirements, such as welding quality. height, the surface of the table should be planed, the position of the mounting holes should be precise, etc..."

"And what about the nose mount under the extreme cold? Not only are these characteristics required to be guaranteed, but it must also be strong and resistant to extreme cold, durability, etc..."

"There are also rotating bodies, anti-wind devices, etc., and the anti-wind devices include tail rudders, steering wheels, electric anti-wind systems, automatic anti-wind rotors, speed control devices, etc..."

"We can even think that this is to redesign the entire wind turbine, tens of thousands of parts, to give it cold resistance, wear resistance, superior surface quality, anti-icing characteristics, etc."

"This level of difficulty is equivalent to an ordinary person starting from scratch, learning electricity, mechanics, physics and mathematics by himself, and designing a brand new wind turbine independently!!"

Netizens who flocked to the post bar saw this popular science post and immediately understood why the Energy Bureau wanted to solicit proposals from across the country.

Because...their in-house engineers may have tried a lot of designs, but in the end they all failed because of the difficulty.

In the end, we can only try whether the power of the masses can work!

The owner's post made many people realize how complicated and difficult the country is designing machines. At the same time, the people's respect for the Emergency Bureau, the Energy Bureau, and the wind turbine designers is even stronger.

A few hours later, there were still many high-quality posts popping up in the post bar.

【Wind Turbine Designer, Southwest Energy Bureau Engineer Zhang Wei】:

"I have done a wind farm project, and I have seen a concept wind turbine before, which uses the kinetic energy of the vorticity oscillation of the wind field to generate electricity. It is relatively new. I will mention it here, and I hope it can attract more ideas."

"Wind, as a kind of fluid, is not a calm and quiet flow, but a calm with fluctuations. Generally, the 10-minute wind speed measured by the wind measuring tower is divided into the average wind speed and the standard deviation. The standard deviation reflects the fluctuation of the wind speed. The ratio of the difference to the mean wind speed is called turbulence."
