June 8, World Ocean Day and National Ocean Propaganda Day. Cui Weicheng and his students smashed his "Rainbow Fish" 10,000 meters deep dream.
In the past two years, Professor Cui Weicheng of Shanghai Ocean University has done dozens of popular science lectures. “From students to civil servants, as long as the time is arranged, the visitors will not refuse.â€
"Wait to say it again." Seeing him preaching 10,000 meters deep dive, some people kindly advised him to keep a low-key point.
Cui Weicheng thanked his friends for their concern but insisted on his own opinion: "I said it was to block the road and fight back."
Once you have an idea, you should quickly chase it.
Three years ago, in 2012, the "Zhenlong" completed a historic bloom, but even the teammates who shared the same boat did not know that Cui Weicheng, the first deputy chief designer, faced the upcoming flowers and honors after the landing. A resignation letter has been written.
"For cutting-edge technology, once you have an idea, you should quickly chase it." He did not want to lie on the "Jilong" to pick "Peach", but to clarify his goal for the next 10 years: to develop the 10,000-meter sea as soon as possible. Deep-working manned submersible.
In 2002, China's 7000-meter manned submersible was established. Cui Weicheng was appointed as the head of the submersible body system project and the first deputy chief designer. In the next 5 years, he participated in the design from the design to the preliminary design. Detailed design process. Beginning in 2009, the whole process of tracking the "Zhenlong" for 4 years of sea trials.
"I wanted to stop the boat in the gully and stink myself." This is not a joke. In the first dive of the 1000m sea trial in 2009, he only "sneaked" to 2.4 meters, which is the depth of the submersible draught.
In 2012, American director Cameron did a major event that shocked the world - driving the "Deep Sea Challenger" to create a 10,000-meter deep dive record.
Although the "Deep Sea Challenger" is only an expedition-type deep submersible, it is impossible to conduct scientific investigations, but its appearance has made the "Zhenlong" and the world's deepest record missed.
Talking about this, Cui Weicheng is still regretful.
In 2013, he resigned as the deputy director of CSIC 702 and established China's first abyss science and technology research center at Shanghai Ocean University.
Scientist + entrepreneur innovation model
Re-starting, capital is a problem he can't avoid.
Generally speaking, cutting-edge technology research and development investment is large, research and development time is long, and the future return is difficult to be clear, mainly relying on official research funding.
Cui Weicheng tried to explore new ways to use private capital to support the country's cutting-edge technological innovation.
"If scientists are willing to approach entrepreneurs, introduce the development trend of cutting-edge technology and the research gaps that the country does not need to fill, and use scientific passion to infect entrepreneurs, I believe that entrepreneurs will be willing to contribute and fund a scientific dream ahead." "The ancestral home of Haimen, Jiangsu, he first found a well-known business township party, but in the face of profit-seeking businessmen, such a statement is somewhat pale.
In the end, the first start-up fund of four or five million yuan came from family members and relatives, of which he himself invested 2 million yuan. "Only if I take out the real money and silver, people will believe that you are serious."
With this funding, the “Rainbow Fish†10,000-meter all-sea deep-operated manned submersible project entered the implementation phase. He began recruiting, setting up a research and development team, and designing a submersible.
Like protecting giant pandas, he creates the “vacuum†environment as much as possible, ensuring that team members have considerable income. They don’t have to write a book to apply for a project, they don’t have to worry about research and development, they just need to bury their heads in technical research.
He positioned himself as a strategic scientist, and formed a "scientist + entrepreneur" innovation model with his younger brother Wu Xin. In the tacit cooperation of "empty gloves and white wolves", "I am responsible for the technology on the tall, the specific matter is the younger brother. To talk. This will improve efficiency and win-win."
On April 18th, the “Rainbow Fish†project took another important step. On the same day, the "Zhang Yu" No. Kakoo mother ship laid a keel at the shipyard. After the ship was completed, it will provide scientific research services for the "Rainbow Fish".
“Zhang Wei†invested 120 million yuan. Lu Yunjun, chairman of Zhejiang Taihe Shipping Co., Ltd., was responsible for raising 90 million yuan. Cui Weicheng and Wu Xin were responsible for raising 30 million yuan.
It was a little weird. It took only over an hour. He and his collaborators contributed to this event at the Shanghai Jiaotong University Café, and spent less than four months to raise all the design and construction costs.
"The private enterprise boss is not a fool, it will be profitable to invest money." Cui Weicheng is more business-minded than before.
Through in-depth discussion by three people, they have written a project feasibility report with very attractive investment: It is expected that the ship will go out for 300 days every year after completion, even considering the use of submersibles for the international and domestic scientific research market, for oil and gas. The company provides deep diving services and sends rich people to the underwater adventure.
After the "Zhang Hao" market was bullish, he and Wu Xin will reduce their shareholding ratio from 30% to 10%. The cash funds will be used for the construction of the manned ball cabin. "It is this way of rolling forward step by step."
"The most important scientific spirit is to dare to adhere to your own views."
One day in May, Cui Weicheng gave the students a science class to go out of school, and the sky was raining heavily. He took the umbrella out of one of the handbags and walked to the nearest subway station to take a ride home.
Most of the two handbags that were carried were his clothes.
In order to save time, he usually stays in the Shanghai Ocean University dormitory away from the urban area, and spends most of his time in the urban office on weekends. With family members, only the weekend meal time is left.
At the age of 40-50, there is a "Dragon", 50-60 years old has a "rainbow fish", and there is a bigger project at the age of 60-70. "Don't be capped at a certain age." This is the life he planned for himself very early.
For his new career, the 52-year-old is full of urgency.
He hopes to realize the abyss technology dream in 10 years before retirement - in 2014, to complete the first full-sea deep lander development; in 2015, complete the development of the unmanned submersible and the construction of the scientific research ship; 2016 The unmanned submersibles and landers use the new scientific research mother ship to impact the Mariana Trench; in 2018, the development of manned submersibles was completed; in 2019, the Chinese were forced to reach the Mariana Trench.
Cui Wei's cost department graduated from Tsinghua University majoring in solid mechanics, but later changed his professional and research direction as needed. Among the many fields involved, he has a special liking for philosophy.
In the lecture, he often talked about "philosophy and life."
"For the scientists who study and use science, the first lesson is not to study science, but to explain why you should study science." Over the years, he has been thinking about the meaning of science and scientific spirit.
In his view, the most important point of the scientific spirit is to dare to question authority and dare to stick to his own point of view.
This is actually to say that I am encouraging myself.
So far, he and his family have lived in an old house of more than 60 square meters in Shanghai. However, he is only responsible for 200,000 of the 600,000 salary subsidized by the “dictatorship†every year, and other income is contributed to the “rainbow fishâ€.
In the eyes of many people, Cui Weicheng’s dream is too big to seem out of reach. He seems to be fully prepared for the risks that may be faced in the future. “Even if the submersible was not made at the end, I did a lot of key technical research. From another perspective, I also let the country choose one more choice.â€
