On November 21st, China's first experimental deep-sea mobile workstation "Dragon Palace" developed by China Shipbuilding Industry Corporation's 702th Institute successfully completed the first phase of the first pool test. This is another frontier exploration of China's deep sea equipment research and development after the successful development of the "Zhenlong" manned submersible. It has laid a technical foundation for the development of a deep-deep, 100-ton deep-sea space station in China.
The experimental deep-sea mobile workstation was developed and supported by the Ministry of Science and Technology and the Ministry of Industry and Information Technology. It was developed by the 702 scientific research project after ten years. The main purpose of this test is to comprehensively verify the overall performance of hydrodynamics such as navigation and maneuvering, submerged floating motion, underwater hovering, and off-basin of the test platform. The test platform propulsion system, power system, hydraulic system, life support system, Submersible floating system, buoyancy control system, trim adjustment system, Guantong navigation system, sealing device, operation auxiliary system and equipment operation reliability, commissioning and inspection test platform control system software information flow and control flow exchange correctness and reliability Sex, verify the reliability and safety of the test platform multi-person, long-term life support, and accumulate the original data of reliable operation and maintenance of the platform, cultivate the test team's driving team and test support team, and lay the foundation for the second phase of the pool test. . It is reported that the experimental workstation will be launched in 2014 for the second phase of the pool test, focusing on the demonstration of underwater operation technology.
The experimental workstation is equipped with 35 tons of equipment. From the appearance, it is slightly flatter than the "Jilong", similar to a kind of squid in the deep sea. The inner diameter is 2.1 meters, the height of the floor is 1.9 meters, and the internal space is five or six square meters, which can accommodate 6 people at the same time. There are two observation windows at the beginning and the end of the workstation. Through the "Dragon Palace Eye", researchers can control the workstation to observe the work of the marine world and the robots released to the seabed. The bottom of the experimental platform is loaded with underwater robots. After the platform is submerged to the seabed, the driver can release the robot and remotely control it for independent navigation. The robot can be as far as 100 meters away from the platform, and the working depth can be up to 1500 meters, which can complete the grabbing and laying work of some objects.
Wen Zhiping, director of the 702, said that the experimental workstation is mainly used to verify and demonstrate the functions of deep-sea workstations. The next step is to build a 300-ton small-scale deep-sea workstation. The future goal is to develop a 1,500-ton, 3,000-ton deep-sea mobile. workstation. In addition to being able to work longer and wider on the seabed, the future deep-sea mobile workstations can also be equipped with many types of deep-sea robots like the carrier platform, and can use the deep-sea submersible like the “Jilong†as a ferry to realize the surface support system. Shuttle transport between the deep sea mobile workstations, personnel replacement, material replenishment, etc. At the same time, the deep-sea mobile workstation can be equipped with a number of “powerful drymen†represented by detectors and robots. They are like the eyes and ears of the workstation. They can walk out 30~50 kilometers, send back the detection signal and complete the task according to the instructions.
