The design principle of Jiaolong, what is the structure of Jiaolong

First of all, the shell is domestic, made of titanium alloy, and is egg-shaped. The introducer told me that the foreign production is two of the four propellers, the foreign production is the left and right two green, relatively large, the domestic is the upper and lower two engines, the color is black, relatively small, these four engines are extremely small energy consumption, the thrust of foreign production is large, the energy consumption is small, the domestic weakness in comparison, the lights are all domestic, including LED, HIM, HID lights, when diving into the sea, only open 5, the remaining five are spare, the manipulator has the ability of "weasel", In other words, if it is entangled in aquatic plants, it can be separated automatically! Jiaolong's safety factor is 150%, which means that there is no problem diving to 10,000 meters!

In case of an emergency, such as in the event of a power outage, ballast (refers to the iron that allows the submersible to dive, the principle is simple and very environmentally friendly!). ) will be thrown away automatically; Jiaolong also has 480 kilograms of mercury, and the buoyancy generated after throwing it away can reach the surface of the sea; There is also a 9,000-meter-long buoy on the back of the "Jiaolong" (domestic), which will catapult to the surface of the sea in the event of a situation, and the mother ship will pull the Jiaolong on the ......

A lot of nonsense is said, but it is also important. Although other countries can dive to more than 10,000 meters, but can not operate, although our Jiaolong dives to 7,000 meters, but can operate, this technology is very few abroad!! Hope!

In order to promote the development of China's deep-sea seaborne technology, provide important high-tech equipment for China's international seabed resources survey and scientific research, and develop common technologies for China's deep-sea exploration and seabed operations, China's Ministry of Science and Technology listed the development of deep-sea manned submersibles as a major special project of the National High-tech Research and Development Program (863 Program) in 2002, and started the self-design and integrated development of the Jiaolong manned deep-sea submersible. Jiaolong manned submersible is designed to dive to a maximum depth of 7,000 meters, and its working range can cover the global ocean area. On June 19, the second test of the 7,000-meter-level sea trial of China's manned deep-sea submersible "Jiaolong" reached a maximum depth of 6,965 meters, setting another record for China's manned deep diving.

Also, you're in the wrong category.

China can build a fully transparent unmanned submersible with only six cameras to take comprehensive pictures of the underwater and underground landforms at 6,000-12,000m.

Jiaolong is long, wide and high, can withstand pressure of 7,000 tons per cubic meter, and its working range covers 100 of the world's oceans, marking that China has become the fifth country with manned submersibles!

I haven't seen it, but the diving is pretty the same.

The Jiaolong submarine is a manned submersible designed and integrated by the People's Republic of China, and it is also a major research project in the 863 Program, with a design depth of 7,000 meters. From May to July 2010, Jiaolong carried out several diving missions in the South China Sea, reaching a maximum depth of 3,759 meters. On July 26, 2011, the Jiaolong manned submersible reached a depth of 5,057 meters.

On June 27, 2012, the metre was reached. On March 17, 2015, Jiaolong officially berthed at the home port at the national deep-sea base at 36°20 120°43. Measuring meters long, wide and high, weighing no more than 22 tons in the air, excluding the weight of the crew, with a payload of 220 kilograms, and a design diving depth of 7,000 meters, it can carry a submariner and two scientists for a total of three people, and can explore the world's oceans, although it is still a considerable distance from the bottom of the Mariana Trench, the deepest known part of the Earth's oceans, at 10,911 meters.

The project began in 2002 and was included in the 863 Program by the Ministry of Science and Technology of the People's Republic of China. A total of about 100 scientific research institutions and enterprises, including the Shenyang Institute of Automation, Chinese Academy of Sciences, participated in its research and development work. The chief designer of Jiaolong is Xu Jinnan, an expert in deep diving technology in China.

On June 12, 2012, Cui Weicheng, deputy director of the 702 Research Institute of China Shipbuilding Industry Co., Ltd., and the first deputy chief designer of the "Jiaolong" manned submersible and the head of the overall and integrated sub-project since 2002, said in an interview with reporters, "In the end, we will make a 11,000-kilometer manned submersible to navigate and operate freely on the seabed in the deepest part of the ocean, so that China will truly become a developed country with manned deep diving." ”

Jiaolong is a manned deep-sea submersible independently designed and developed by China, whose construction began in 2007 and was successfully launched in 2009. Jiaolong's range of use is the deep sea, with a maximum depth of 7,000 meters, and the depth expansion research is still being carried out. Jiaolong's main mission is to conduct deep-sea scientific investigations, deep-sea resource surveys and development.

As a milestone in the history of China's marine science and technology development, Jiaolong demonstrates China's strength and exploration spirit in the deep-sea field.

It should be noted that the operation principle of Jiaolong is that the deep-sea submersible is hooked to the mother ship to launch dives, and the deep-sea submersible communicates with the mother ship through radio. Jiaolong uses world-renowned parts and components, with good reliability and stability, so that its indicators in the deep-sea environment have reached the international leading level.

The use process of Jiaolong is as follows: the mother ship lowers the submersible to the surface of the sea, enters the field and enters the diving state, and then begins to dive. During the dive, the crew of the Jiaolong will make depth adjustments based on the data collected in real time to ensure the safety and reliability of the diving process.

After reaching the target depth, Jiaolong will conduct seabed surveys and samples, and bring the samples back to scientists for analysis. After the collection is over, the Jiaolong will refloat and approach the mother ship, which will then fish it to the surface for ** and overhaul.

All in all, Jiaolong is an important practical achievement of China's deep-sea scientific exploration and development, and its release and use marks a significant improvement in China's marine science and technology strength. Through the continuous expansion and development of Jiaolong, we believe that the future of the deep-sea field will be more beautiful and bright. <>

Jiaolong is very advanced and can be said to be the leader of deep-sea submersibles in the same industry.

Jiaolong"The manned deep-sea submersible is China's first self-designed and integrated deep-sea manned submersible, with a designed maximum depth of 7,000 meters, and it is also the deepest operational manned submersible in the world. "Jiaolong"It can be used in the vast sea area that occupies the world's ocean area, which is of great significance for China to develop and utilize the resources of the deep sea.

Deep-sea manned submersibles are equipment that can carry scientists, engineering and technical personnel, various electronic devices and special equipment to quickly and accurately reach various complex deep-sea environments for efficient exploration, scientific investigation and near-seabed operations, and are an important technical means for the peaceful development and utilization of deep-sea resources.

According to reports,"Jiaolong"The main missions that can be carried out by the manned submersible include two aspects: on the one hand, it can carry scientists and engineers and technicians into the deep sea, maneuver, hover, correctly position and sit on the complex seabed such as seamounts, ocean ridges, basins and hydrothermal vents, and effectively carry out scientific investigations of marine geology, marine geophysics, marine geochemistry, marine earth environment and marine anthropomorphic biology.

1. Jiaolong manned submersible.

It is a manned submersible designed and integrated by China, and it is also the 863 program.

is a major research project. From May to July 2010, the Jiaolong manned submersible was in the South China Sea.

Several dives have been carried out, and the maximum depth of the dive has reached 7020 meters.

In the year, China's Ministry of Science and Technology listed the development of deep-sea manned submersibles as a major special project of the National High-tech Research and Development Program (863 Program), and started the self-design and independent integrated development of the "Jiaolong" manned deep-sea submersible. From 2009 to 2012, the 1000-meter, 3000-meter, 5000-meter and 7000-meter sea trials were successfully achieved. June 2012 in the Mariana Trench.

It has set a record for China's manned deep diving of 7,062 meters, which is also the world's largest diving depth record for similar operational submersibles. On December 18, 2014, he dived into the Indian Ocean for the first time.

Technical features:

Technological advantages. 1.It has the largest diving depth of its kind in the world at 7,000 meters, which means that the submersible can be used in a vast area of the world's oceans;

2.It has a stable hovering for the operation target, which provides a reliable guarantee for the submersible to complete the high-precision operation task.

3.It has advanced underwater acoustic communication and seabed micromorphology detection capabilities, which can transmit images and voices at high speed and detect small targets on the seabed;

4.Equipped with a variety of high performance, it ensures that manned submersibles can complete complex tasks such as fidelity sampling and submersible drilling and coring under special marine environments or seabed geological conditions.

Three breakthroughs. Near-bottom automatic navigation and hovering positioning, high-speed underwater acoustic communication, and oil-filled silver-zinc battery capacity are well known"Jiaolong"The three major technological breakthroughs:

1.Stable"Stay"

Just like driving a car, the driver's feet are always on the accelerator, which inevitably causes fatigue. "Jiaolong"Luckily, the pilot has an automatic navigation function, and the driver can rest assured that he can observe and conduct scientific research after setting the direction.

Wang Xiaohui said"Jiaolong"There are three types of automatic navigation that can be completed: automatic directional navigation, after the driver sets the direction"Jiaolong"It can sail automatically without worrying about mistracking; Automatic altitude cruising, this function can keep the submersible at a certain height from the seabed, although the submarine mountain is undulating, the automatic altitude setting function can be"Jiaolong"Navigate complex environments with ease and avoid collisions; Automatic depth fixing function, can be allowed"Jiaolong"Keep a fixed distance from the sea.

2.Hover positioning.

Once the target is found on the seabed,"Jiaolong"It is not necessary to sit on the bottom like most foreign deep submersibles, but the driver drives to the corresponding position"Stay"position, keep a fixed distance from the target, convenient for the manipulator to operate. Caused by ocean currents at the bottom of the sea"Jiaolong"Under the internal and external interference such as swaying and manipulator movement driving the entire submersible, it can be done accurately"Hover"Commendable. In the published information, no foreign deep submersible has yet been equipped with similar capabilities.

3.Deep-sea communications rely on"sound"

Land communication relies mainly on electromagnetic waves, which can reach the speed of light. But this weapon is useless in the water, and the electromagnetic waves can only penetrate a few meters in the seawater. "Jiaolong"Diving thousands of meters into the deep sea, in order to maintain contact with the mother ship, scientists have developed a high-speed underwater acoustic communication technology with the world's advanced level, using sonar communication.

This technology needs to solve a number of problems, such as the underwater acoustic propagation speed is only about 1500 meters per second, if it is 7000 meters deep, it takes nearly 10 seconds to shout a sentence back and forth, and the sound delay is very large; The bandwidth of acoustic transmission is also extremely limited, and the transmission rate is very low; In addition, the propagation effect of sound in uneven objects is not ideal, and the density of seawater is different, the temperature is different, the seabed echo conditions are also different, and the noise on the mother ship and deep submersible makes it more difficult to effectively extract signals in complex environments.
