China will build a seven dragon exploration system and develop the South China Sea just around the corner.


"Dragon", "hidden dragon" and other Chinese deep-sea research artifact have been affecting the attention of the domestic and international. Before and after the summit, the Global Times reporter entered the national deep-sea base management center in Qingdao, with close contact with the four "artifact" of China. According to Ding Zhongjun, deputy chief engineer of the national deep sea base management center, the next step will be to build a deep-sea three-dimensional exploration network of "seven dragon exploration sea". The "seven dragon" equipment is also expected to enter the South China Sea and other key areas for the maintenance of maritime rights and interests in the South China Sea, to obtain first-hand deep-sea samples and data, to increase the voice of China in the deep sea exploration field, to help China better safeguard the global marine security and marine rights and interests.

"True and false" Dragon

Into the deep-sea base submersible maintenance workshop, the first eye of the global times was attracted by the red and white body of the "dragon", the first deep-sea manned submersible, while the other side of the workshop was the "dragon" simulation training system. The true and false "dragon" in the workshop across the air: one is a weapon for the war, and a support and support for this weapon to provide personnel training, equipment testing and so on.

According to Gao Xiang, a senior engineer of the Technology Department of the state's deep-sea base, the development of a manned submersible simulation training system to carry out simulation training and full process task safety training of the submarine and submersible personnel is of great significance as the "dragon" application is maturing. At present, the simulation training system has basically completed the design goal, is being optimized and perfected, and will soon be put into trial application.

The Global Times reporter observed that the "dragon" simulated the size of the cockpit is exactly the same size as a real boat. It is a sphere with an inner diameter of 2.1 meters, and three diachrons can only move in a round space of about 1.4 meters in diameter. It is reported that the "dragon" a submersible task is about ten hours, usually about 7 o'clock in the morning, in such a narrow space to complete the submersible task, to the dive crew is a very big challenge.

The Global Times reporter can see simulated underwater creatures and geological phenomena, such as lilies, cliffs, and cliffs, from the location of the simulated cockpit owners through the glass.

Ding Zhongjun told the Global Times reporter that this is the world's only manned submersible simulation driving training system, which can simulate cruise operations and trouble shooting, and provide good hardware conditions for the training of integrated divers, submersible scientists and maintenance engineers.

In another workshop, the most advanced autonomous unmanned submersible "buried dragon" three, ten thousand meters deep-sea unmanned remote control submersible "Hailong 11000" and the "deep dragon", which can be sampled at the bottom of the 4000 meter deep rock drilling, lie quietly beside the test pool. It is reported that the entire pool is 10 meters deep, 20 meters wide and 70 meters long, and is currently the largest submersible test tank in China. All the trials of "dragon" were laid out, diving and recycling.

Compared with the design of the "dragon" and "dragon", the design of "Hailong" is open, and the metal frame and cable are completely exposed in the air. According to Ding Zhongjun, "sea dragon" through the core attached to the equipment, by sacrificing the anode protection to ensure that the body of the submersible under the submarine to the depth of 11 thousand meters, not subjected to seawater corrosion, to achieve normal operation.

The next step: "the Seventh Dragon" in the South China Sea

It is understood that the "dragon" will start a one year global voyage in June 2020, and the South China Sea, a strategic area for the study of China's deep sea, will be a necessary place for the mission. Ding Zhongjun told the Global Times reporter that the "dragon" can play an important role in scientific research, resource exploration and environmental research in the South China Sea.

Ding Zhongjun revealed that the "dragon" can sink to the bottom of the 7000 meters, which is the deepest manned submersible in the world. The largest depth in the South China Sea is four or five km, which is one of the most suitable sea areas for the dragon. Ding Zhongjun said that the South China Sea science problem is relatively concentrated, rich in resources, strategic position is very important, is an important global route, the "dragon" just can play its advanced technical advantages, and help the scientific research of the deep part of the South China Sea.

Zhu Feng, executive director of the China South China Sea research collaborative innovation center, Nanjing University, told the Global Times reporter that about more than 40 thousand ships pass through the South China Sea every year from the channel resources. Japan, South Korea and China, including Taiwan, have more than 90% of their oil imports depending on the South China Sea channel. Liquefied natural gas (LNG) transported through the South China Sea is 2/3 of the world's total trade volume. More than half of China's nearly 40 routes to foreign countries pass through the South China Sea.

Ding Zhongjun stressed that the manned submersible into the deep-sea research in China, especially the deep-sea research in the South China Sea, has a milestone, its fine work ability and near bottom investigation ability is very strong, other equipment can not be compared. At the same time, the greatest advantage of the "dragon" is that it can carry scientists directly to the bottom of the sea, give full play to the subjective initiative of the submersible scientists, carry out detailed investigation and fine sampling, and provide one hand data for our deep-sea scientific research.

In 2013, the Dragon dragons dived into the cold spring area of the South China Sea for two times, and successfully obtained a lot of biological and geological samples in the cold spring area. In April 2017, the "dragon" 4 days 3 to explore the South China Sea, the samples and data obtained are of great significance to the genesis of the South China Sea seamount chain, the tectonic evolution of the South China Sea and the study of the biodiversity in the South China Sea.

Ding Zhongjun told the Global Times reporter that with the development of the "dragon" new mother ship, in 2020 the global voyage, the "dragon" "dragon" and "Dragons" are expected to achieve the scene of the three major equipment. Ding Zhongjun revealed that by the end of 2020, it was more likely to see that the equipment system of the seven dragon exploration system was basically shaped, and that the "seven dragon" exploration of the South China Sea is just around the corner.

"China's research and development of heavy marine resources is not to grab resources."

In Ding Zhongjun's view, the launch of the 11 thousand meter manned submersible under the sea was marked. In 2021, China was expected to lead the development of major deep-sea equipment for better maintenance of the world's maritime rights and interests, marine environmental protection and global marine governance, and to promote the co construction of the fate of marine human beings. Androgyny.

"At that time, how deep the sea is in the world, how deep can China's deep diving equipment go," Ding Zhongjun said.

"The goal of China's deep-sea equipment is to go to the international sea, to obtain first-hand data and samples, to provide a new understanding of the scientific problems in the international sea area, so that China will be more utterance in participating in the international ocean affairs, and can participate in the formulation of rules and deep participation in the global deep-sea governance." Ding Zhongjun added. As a responsible country, China needs to use the heavy weapons of the country to participate in the maintenance of global marine security, not to seize the resources, but to contribute to the common development of all mankind.
