Science and Technology Xinghai 丨 Zhejiang "helicopters" can take off and hover by 1000 meters underwater

How to grab the high point of marine science and technology? A few days ago, the "Zhejiang Provincial Science and Technology Xinghai Leading Action Plan" drew a line for Zhejiang — to go to the deep sea, deep blue, polarity and other fields to fight.

Looking at the map, the south to Wenzhou Cangnan and Shengsi, Zhoushan in the north. The winding coastline was frame, and the vast sea area of ​​260,000 square kilometers was frame, which laid the confidence of the Zhejiang marine province.

However, in the "three armies" of the earth, geology, and atmospheric sciences on the earth, Zhejiang's "Navy" started late, and we only had a different approach.

The deep sea usually refers to sea areas with water below 200 meters. As the latest world of human cognition on the planet, the deep sea floor contains endless treasures, and it is still full of many scientific mysteries.

Can the track compete, can this stick be connected in Zhejiang?

152 years ago, French writer Reller Verina wrote a famous book "20,000 Miles under the Sea". With the development of deep diving technology, the story of the "Nautilus" traveled to the deep sea is no longer the fantasy of that year.

In the South China Sea, 1,000 meters underwater, a "underwater helicopter" that can complete technical actions such as "take -off", "air" suspension, 360 -degree rotation in place, and 360 -degree rotation in place, take off from the underwater base station to carry out submarine observation tasks. This is a key scientific research equipment developed by Professor Chen Ying of Zhejiang University Ocean University of Ocean.

In the field of vision of scientific researchers, the underwater world is not barren. From time to time, it is seen that sea cucumber, sponge, starfish, fish, shrimp and other animals. Many details coincide with the description in "20,000 Miles of the Sea".

"The prototype of the sea test is like a flying saucer, with a diameter of 1.5 meters, with electrical energy as the power, and has a strong maneuverability. The flat disc design makes the horizontal contact area of ​​the body's horizontal direction. Stability. "Professor Huang Haocai, a member of the project team and Professor Huang Haocai of the Zhejiang University Ocean Academy, told me that" underwater helicopter "can land at the underwater base station charging and transmit signals, and realize the data between the underwater base stations.

Go down, keep down. As Huang Haocai said, in the field of deep -sea fields, Zhejiang has been in the stage of crossing the river in the past few years in Zhejiang, and now it is a critical moment when science and technology are promoted.

Every time the sea is deepened by 10 meters, an atmospheric pressure is increased, the deep sea is explored, and the pressure of shoulder can be imagined.

Science and technology are booming, and if you do n’t enter, we will retreat. How can we retreat?

During the period when the geography of the world was a big deal, many marine scholars attempted to know how deep the ocean was. The methods they use are very simple. People stand on the bow and hold a long rope. There are hammer -shaped iron or lead blocks on one end. When the heavy hammer touches the bottom of the sea, write down the length of the rope, that is, the sea is the sea, that is, the sea is the sea. deep.

For scientists who chase roots, these are not quenching. Biologists want to know if there is a biology in the abyss of 10,000 meters? Geologicalians want to know if there are minerals and oil there? Exploring the mysteries of nature has made them common ideals, and go to the abyss to take a look. For many years, the slogan of entering the army has been inspired to move forward, leaving many moving stories.

On August 10, 2013, researcher Wang Chunsheng, the Second Ocean Research Institute of the Ministry of Natural Resources became the first scientist to dive with the Dragon Dragon in the Pacific Ocean. reality."

Prior to this, Wang Chunsheng also went to this seas to investigate seven times, but before he watched the underwater video or biological sample, this time it was observed in real time by a submersible. "When I saw the bottom of the sea, I was shocked by the wonderful underwater world!"

There must be confidence in trying deep sea.

Try it, trial is the courage of Zhejiang people to catch Jiuyang. The courage of Zhejiang people is not afraid of the wind and waves. The trials are the confidence of Zhejiang people who will hit three thousand miles of water.

The upgrading of marine provinces to strong provinces requires science and technology blessings, and only science and technology blessings.

With deep -sea technology, how to open up the innovation chain and the industrial chain, and continue to lead the strategy of rejuvenating the sea?

Since mid -May, the Zhejiang University project team has launched a lake testing in the Golden Bay Reservoir of Zhoushan to further deepen the "underwater helicopter" technology. "Through the test, the stability of the independent operation of underwater helicopters has been further improved, the operation capacity of underwater helicopters is enriched, and the foundation for subsequent applications and industrialization." Huang Haocai said.

The person in charge of the relevant department of the Provincial Department of Science and Technology stated that in the future, the key technologies of the deep -sea exploration should be used to build the "deep sea entry -deep -sea exploration -deep sea development" capabilities as the orientation. , Intellectual monitoring station, deep -sea exploration operation equipment and other underwater loading and intelligent equipment, tactics such as heavy environmental environments such as heavy anti -corrosion coatings, buoyancy materials, and pressure -resistant structure materials, etc. The key basic parts of marine equipment such as hydraulic motors such as ships are manufactured to build the advantages of deep -sea poles.
