In the eyes of children, it is "scoring points like crazy" in the deep sea

Recently, the "Knowledge is Power" science reporter checked in at the Chinese Scientists Museum, listened to the exhibits telling of China's scientific and technological development, and witnessed the shining spirit of scientists.

The "Father of Jiaolong" who builds dreams in the deep sea

Xu Qinan is a deep-sea submersible technology expert and chief designer of Jiaolong.

He devoted his life to studying deep-sea submersible technology and was hailed as the "Father of Jiaolong" who built dreams for the deep sea.

He is one of the first batch of talents trained for deep-sea research and development in my country. From an initial ship service soldier to a scientific research leader, he has witnessed the development of China's submarine science from scratch.

In 2002, Xu Qinan served as the chief designer of Jiaolong, a 7,000-meter manned submersible designed and independently developed by my country. He is the founder of my country's deep-sea submersible development field.

The development of deep-sea submersibles is a world-class scientific and technological challenge. For a long time, my country has made some achievements in both "going up to the sky" and "going down to the ground", but has been unable to find any success in "going down to the sea".

Xu Qinan refused to give up. He led his team to build China's first pressure cylinder equipment in just three years.

The Jiaolong manned submersible began development in 2002 and made its first dive in 2014.

It is my country's first deep-sea manned submersible that is independently designed, integrated and developed, and has independent intellectual property rights.

The Jiaolong is capable of deep-sea prospecting, high-precision seabed topography measurement, detection and capture of suspicious deep-sea objects, and exploration of deep-sea life, and other survey functions. It is a "powerful weapon" for my country to build a maritime power.

Although my country started late in research on manned submersibles, the breakthroughs and achievements made in recent years have attracted worldwide attention.

In the face of long-term technological blockades, my country has successively carried out the development of the Jiaolong, Deep Sea Warrior, and now the Fendouzhe manned submersibles, making my country's manned submersible technology gradually reach world-class levels.

After visiting the Museum of Chinese Scientists and learning about the story of Xu Qinan and the Jiaolong, the Zhili Science Journalists were deeply touched. Come and listen to their thoughts on the museum!

Carry forward the spirit of scientists and tell good stories about them. Hello everyone, I am Kang Jingyi, a science reporter for "Knowledge is Power".

Today I visited the Museum of Chinese Scientists. I was greatly shocked by the many exhibits here. The one that impressed me the most was the story of Grandpa Xu Qinan and the Jiaolong manned submersible.

Grandpa Xu Qinan is an outstanding scientist in the field of deep-sea exploration in my country. With his infinite passion and firm belief in deep-sea exploration, he led his team to overcome numerous difficulties and successfully developed the Jiaolong manned submersible.

During the development process, they faced many challenges, such as technical difficulties, lack of funds, lack of experience, etc. But they never gave up. They kept experimenting, improving, and innovating, and despite countless failures, they still kept moving forward.

Finally, the Jiaolong manned submersible was successfully launched and set an amazing record of diving to a depth of over 7,000 meters! It gave us a deeper understanding of the mysteries of the deep sea.

We can get a lot of inspiration from Grandpa Xu Qinan’s story.

First of all, you must have a firm belief and an indomitable spirit. No matter how big the difficulties are, you must not give up easily. You must believe that as long as you persist, you will succeed.

Secondly, we must have the courage to innovate. When facing unknown areas, we must dare to try new methods and ideas, and continue to explore and break through.

Finally, teamwork is crucial. The success of Jiaolong is not the result of one person's efforts, but the result of the concerted efforts of the entire team.

I will take Grandpa Xu Qinan as an example, face challenges bravely in study and life, work hard to pursue my dreams, and contribute my own strength to the prosperity and strength of the motherland!

The Chinese Scientists Museum is China's first large-scale comprehensive museum with the theme of scientists. It integrates the functions of "collection, collection, research, display, education and publicity" and aims to showcase the image of Chinese scientists and promote the spirit of scientists.

We will continue to release information about related activities at the Museum of Chinese Scientists, so stay tuned and welcome to visit!
