The physics laboratory on the second floor is very large, with more than 200 square meters, which contains PASCO experimental systems, electromagnetic dot timers, force sensors, charge sensors, electrostatic teaching boxes, 1.2m classical kinetic guides, two-dimensional magnetic field demonstrators and Faraday cages and other instruments and equipment.

A large event space has also been set up for the activities of interest groups.

There are about 20 members of the invention and creation interest group in it, Gu Yu saw at a glance, most of them are senior seniors in the second and third years of high school, mainly boys.

To Gu Yu's surprise, Ouyang Qingsha, the "school flower" who ranked first in the boys' mouth, was actually in this group.

For this National Youth Invention and Innovation Competition, Gu Yu had heard of it in his previous life. He saw an online news that a candidate from Henan named Chen Tianhan invented the universal charge when he was 18 years old, so he won the first prize of the National Youth Invention and Creation Competition, and was finally escorted to Tsinghua University......

At present, the National Youth Invention and Innovation Competition is linked to the college entrance examination bonus points and guaranteed delivery, and students who have won the first and second prizes in the senior secondary education stage can add up to 20 points when they submit to colleges and universities. The outstanding winners were even directly admitted to well-known universities such as Tsinghua University......

Therefore, the students who signed up for this National Youth Invention and Innovation Competition in Minghai No. 1 Middle School were very enthusiastic and enthusiastic, and there were many projects that signed up.

However, it is rare to be able to screen out the many entries and enter the eyes of the teachers.

Therefore, the students who can be selected into this group are the best and most creative geniuses in the school......

Gu Yu was also by mistake, after obtaining the patent, he was accidentally known by a staff member of the Municipal Association for Science and Technology, and when he came to Minghai No. 1 Middle School to guide the science popularization work, he recommended him to the school and Zhu Qifeng by the way.

Mr. Zhu Qifeng is one of the instructors of this interest group and the main person in charge.

At present, everyone is nervously preparing for the upcoming 9th National Youth Invention and Creation Competition.

"Ladies and gentlemen, come on, let's stop what we're doing for a while!" After Mr. Zhu Qifeng clapped his hands, everyone finally paused.

"Next, we ask everyone to take turns on the stage to briefly introduce the progress of their respective works......"

Zhu Qifeng glanced at Ouyang Qingsha in the audience and said, "Either ask our team leader Ouyang to come first!" ”

"Well, okay, Mr. Zhu."

After hearing this, Ouyang Qingsha came to the podium generously, shook her hair, and held up a model in her hand to start a serious explanation.

"I designed a wave generator. The so-called wave generator is a type of power generation that converts the energy of waves into electricity. ”

"My generator plans to use the undulations of the waves on the sea to drive the float up and down, and then use the cooperation of the ratchet on the float to turn the wave into rotation to drive the generator to generate electricity. The two floats vibrate up and down with the undulations of the waves to drive the connecting rod, and then increase the rotation speed through the variable speed gear to drive the power generation ......"

Wave generator, the first feeling to Gu Yu, this technology is very high.

"My work is an automatic feeding chicken feeding device......

"My work is an automatic observer of the water level in a rice field......"

"My work is a moon phase demonstrator......"

The works introduced by the next team members are very scientific and technological, which makes Gu Yu secretly surprised, it seems that this Minghai No. 1 Middle School is indeed a place where the dragon and the tiger are hidden.

"Finally, please introduce Gu Yu's works."

"Actually, my work is very simple, it is a kind of water dispenser with a special filtration device."

After Gu Yu came to the stage unhurriedly, he began to introduce, "At present, most of the water dispensers on the market use bottled water, because the outside air will continue to enter the bucket when the faucet is released, and the bacteria in the air will seriously pollute the water quality of consumers' drinking water after a long time." Therefore, the work I designed is a water dispenser to overcome the problem of secondary water pollution......"

Since there were no physical products on the scene, Gu Yu's introduction on the stage seemed to be very empty.

Immediately, some members of the audience whispered, "His idea seems to be too idealistic, I feel that it is unlikely to ......"

"Well, rhetoric, unrealistic......"

"A rookie in the first year of high school, I haven't taken out any samples, utopianism!"

Gu Yu found that Ouyang Qingsha in the audience didn't even look at him, with a walkman in her ears, buried in her research on her wave generator.

Gu Yu's introduction was very simple, he was afraid that it would be too complicated, and the rookies below would not understand, and he didn't need to explain it to them so carefully......

After Gu Yu stepped down, Mr. Zhu Qifeng came to the stage and added:

"Students, do you know that the new water dispenser technology introduced by Gu Yu just now has obtained the utility model invention patent certificate issued by the State Intellectual Property Office!"

"This is also the first student who has applied for a national invention patent certificate since I came to our school to work!"

Teacher Zhu Qifeng's supplementary introduction finally alarmed the group members in the audience.

They all looked at Gu Yu in the corner of the window: Oh go, it's too good, right? I actually got the national patent certificate in the first year of high school!

This time, even Ouyang Qingsha raised her head, threw her gaze at Gu Yu, and began to pay attention to this boy......

However, soon there was a boy named Feng Jimin who was in the same class as Ouyang Qingsha, who was also a rich second generation, and his father was a private entrepreneur who produced auto parts products.

Feng Jimin whispered to the surrounding team members in a very disdainful tone, "Isn't it just a utility model patent, what's so great, spend some money and spend some time, we can all apply for it!" What is really powerful is the invention patent, that is the original technology, only valuable! ”

It sounds like this Feng Jimin may be influenced by his father and seems to know more about patented technology. The design work he has at hand is an automatic chicken feeding instrument, which sounds much more technical than Gu Yu, and the market is also very extensive.

Soon, many boys said, "Oh, yes, it's not just a practical patent, it's not a big deal!" It's still much more powerful than the works we all have at hand......"

Gu Yu heard Feng Jimin's discussions, remained silent, and smiled.

Finally, Mr. Zhu Qifeng clapped his hands and signaled everyone to be quiet.

"Students, everyone should hurry up and take out the final works and design schematics before the end of this month and October 30th! We will submit it to the province on November 2 to participate in the selection. Finally, the award-winning works of the province will participate in the 9th National Youth Invention and Creation Finals to be held in Hong Kong at the end of December! ”
