Automotive Black Technology Chapter 1381: : Not worth mentioning!
www.lnmao.org, the fastest update to the latest chapter of automotive black technology!
After some intense preparations, more than a dozen Jiaolong underwater detectors were once again installed on the huge hands of the man-made robotic arm.
Different from before, this time, the treatment received by Zhengxin's team has been significantly improved; the underwater staff were busy helping out, shouting at Zhengxin's technicians and engineers about their work. . Even within the 35D command cabin, a special area has been set up for Zhengxin’s engineers, Li Fanyu, Liu Qing and others to observe the underwater construction conditions.
On the side of the work ship, the CCTV news reporters who had received orders were also fully armed. They looked for opportunities to ask questions to Zhengxin's technicians and Liu Qing and others, recording everything about the project throughout the process.
While Zhengxin is busy here, the hydraulic lifting system over there is also being inspected after being launched into the water for the final underwater assembly.
The hydraulic lifting mining system is actually a set of things that fully utilizes the water pressure on the seabed.
The main structure consists of a mechanical composite collector, a lifting ore transportation system, a measurement and control system, a water surface support buoyancy system, and a large underwater auxiliary propulsion system.
It's complicated to say, but it's not difficult to understand.
The mechanical composite collector is like a large shovel, and its function is to collect manganese nodule ores underwater.
Although it is called a "machine", it is much larger than an ordinary "machine". The Russian Nimiyan-type collection system used in the 15220 project is composed of two mechanical composite collectors connected in parallel.
How big is this thing?
The size of a single collector is fifteen meters long, five meters wide, and three meters high!
At the bottom of the collector, there are 34 pairs of cylindrical runner buckets made of titanium alloy. These buckets are like ancient Chinese waterwheels, using underwater high negative pressure to drive and rotate. , shoveling everything they encounter into crumbs.
Then, these debris are collected by the collector, and through negative pressure pipelines, relying on the strong pressure of the seabed, these minerals are directly transported to the lifting system, and finally sprayed onto the mother ship on the water surface through the measurement and control system!
Because the length of this customized Nimi Yang hydraulic lifting system is too large, it is extremely difficult to actually operate it underwater after being assembled at the sea surface.
And because it is all customized, if something goes wrong in every link and the system is damaged, too much time will be wasted in replacement parts and repairs.
So, just to be on the safe side. The assembly and docking of the three links of the collector, auxiliary thruster, and Yang mine system can only be completed underwater.
After some preparations, the sea surface work was completely completed.
After receiving the reports prepared by all working groups, Lu Ming issued the order for construction.
"Brother Fan, holy shit, this looks so exciting! Such a big job always feels very exciting."
Li Fanyu nodded as he looked at the mechanical parts of four or five large work ships stretching out on the sea, as well as the underwater pipelines each of which was a thousand meters long.
"Yes, technology is constantly advancing, and humans can now do many things that were unimaginable before."
"Hey, Brother Fan, you are bragging!" Liu Qing pointed at the Jiaolong underwater detector that had started diving on the water, and said with a smile.
"Uh," Li Fanyu shook his head, "Haha, of course, this project would never be possible without us. But think about it, Maozi's set of hydraulic lifting equipment is also a groundbreaking one. Something. Qingzi, the human robotic arm is a tool. I wonder, with such a set of tools, can we accomplish more things that we didn’t dare to think about before?”
Liu Qing nodded thoughtfully, "Brother Fan, don't worry about this. The modification work of the mechanical shikigami has already begun, and with the addition of the manned robotic arm, our manufacturing strength will definitely be improved. magnitude. In the next operation of the power company, we will definitely develop to a more steel-framed place."
Li Fanyu nodded, smiled and patted Liu Qing's shoulder.
Just as the two of them were talking, more than a dozen Jiaolong underwater detectors had already dived to the predetermined location. According to the plan developed by Russian experts, the joint construction team and the Zhengxin technical team, the assembly process of the entire hydraulic lifting system extends downward from the water surface.
Taking into account the underwater environment and assembly difficulty, Russian delivery experts gave an estimated assembly time of 40 minutes for the first section of the automatic control system and buoyancy body, and 2 hours for the second section of the lifting system. The assembly time of the third section of the submarine hydraulic composite mechanical collection system is 2 hours and 40 minutes.
The entire assembly project will take up to six hours!
This has made many people deeply worried about the underwater stability of the Jiaolong and the pump core robotic arm.
"Director Li, is there any problem with your robotic arm? We have been preparing for this final assembly plan for more than two months."
In the command cabin, Xing Dongliang from the Marine Survey Bureau walked up to Li Fanyu and asked sarcastically.
After all, Zhengshin had previously removed all the robotic arms, citing design flaws or perhaps too much drama. Many people in the joint construction team believed it to be true.
Seeing a group of people looking at him with the same eyes as Xing Dongliang, Li Fanyu smiled slightly.
"Don't worry, if there is a problem that delays the entire assembly progress, then I can guarantee that it will never occur on the robotic arm."
Under the hull of the work mother ship, underwater welders are busy assembling buoyancy fixing facilities. With a large number of bubbles, the underwater welding work of the buoyant body is underway.
At a depth of about 200 meters below them, fifteen Jiaolong underwater detectors have begun to assemble the automatic control system!
The entire assembly work requires riveting and threaded docking to complete a main interface and 22 fixed positions.
The fifteen Jiaolongs were working in pairs at this time, working together to connect the three-meter-diameter hose to the interface of the work mother ship. Looking from the water, the fifteen Jiaolongs looked like a small group of ants, working together to carry prey that was several times larger than their own size back to their nest!
With extraordinary precision, the threads of the two large interfaces were successfully connected after only one use!
And those 22 fixing bolts are nothing to mention for the Jiaolong and the robotic arm which only have a working depth of 200 meters!
Just fifteen minutes later, a report from the underwater working group was received in the 35D command module;
"The first section of docking work has been completed!"
