Chapter 886 Fish a sunken ship for fun?

The next test was also very successful, the dive depth reached 400 meters - this is the result of Lin Dong's stop - although the thruster can still dive below 400 meters, but was stopped by Lin Dong.

This is the civilian version of the underwater thruster. There is no need to dive that deep. The current depth is sufficient.

400 meters underwater, it is already pitch black, the two headlights of the underwater thrusters, and the luminous sticks thrown forward along the way, let the 400-meter-deep seabed basically be clearly seen, big and small strange The underwater species were displayed before everyone's eyes, and even a glimpse of the tentacles of a giant squid flashed by, which shocked the operator!
In fact, it is far from being in the monitoring room as it is in the thruster, but even so, many people in the monitoring room were really eye-opening after seeing the end!

"When they come back, I must make a copy of the thruster's surveillance video and take a good look at it!"

Although most of the people present were old military workers and shipbuilding technicians, none of them had actually been to the bottom of the sea—especially the bottom below 400 meters!

"Necessary, I want to make a copy!" Another person said with a smile: "It looks so real, this is the real seabed. I used to see it on TV when it is below a few hundred meters. Low-light imaging, black and white things look really unpleasant!"

"Don't worry, when our real underwater luxury yacht is built, let's go down and have fun together!" Lin Dong said with a smile: "It doesn't need to be as complicated as a scientific research, let's treat it like an ordinary tour!"

When Lin Dong said that, he naturally had such confidence.He not only provided the military with the technical information of the propeller, but also provided the formula of the propeller shell material, motor, battery, supporting pipeline and operating system.Lai Tongguang reported before that the formula test of the material was very successful. It is resistant to high pressure and corrosion. Not to mention 400 meters underwater, even 1000 meters underwater, it can also withstand water pressure, and there will be no submarines that often appear in film and television programs. The case rattled due to excessive submersion.

And just when the thruster was about to return, Lin Dong asked for an additional test.

"I remember that in the technical information given, there is something about the propeller carrying the buoy. Is it brought here?"

"Bring it!" Lai Tongguang nodded and said, "The two buoys are ready for salvage."

"Then find a seabed about 200 meters deep, and use buoys to salvage something up!" Lin Dong said, "Anything like a reef will do, as long as it weighs about one ton. I remember that the thruster's operating system has a complete automatic salvage program." , Test it and see if it works!"

Lai Tongguang hesitated for a moment, and said in a low voice: "Boss Lin, this system does exist, but I haven't tried it in the previous preliminary test. I don't know if the operator can operate it proficiently..."

"It's okay, let them try it!" Lin Dong said with a smile: "It's best if it works. If it doesn't work, let's modify it. This program is very important, and it is related to the positioning and function of our product in the future. It is best This time the test came out."

What Lai Tongguang said has actually exposed some problems.They must have tested it before, the scale is not clear, but it is certain that it must have been launched, and the initial test of speed and depth was successfully carried out. Of course, it may also be just launched to see if there is any water leakage and how the underwater propulsion is. etc.

Lai Tongguang nodded, and then said into the microphone: "The third and last test will be carried out next. Swordfish, you find a piece of seabed within 200 meters, and use buoys to salvage a piece of reef within one ton. This test If you want to use the automatic operation of the system, you must pay attention to it, if the situation is wrong, immediately cancel the system task, and then come up!"

"Swordfish received!" After the operator replied, he started to move.

Because the thrusters are operated fully automatically, there are only two operators inside. After receiving the instructions, they immediately floated the thrusters up, and after reaching a relatively flat sea area, they began to search for the target.

The situation at the bottom of the sea is complicated.The complexity here is not that the original seabed environment is complicated, but that the seabed is full of broken fishing nets, waste tires, broken ships, ironware and other garbage thrown by humans. The monitor of the thruster wants to see a flat piece that has not been "polluted" "Crossing the bottom of the ocean is hard.

After searching for a long time, I saw all the rubbish and no reefs of suitable size at all. The people in the monitoring room were a little impatient. Lin Dong watched and suddenly picked up the microphone and said to the operator: "There is no need to look for reefs any more. , just the wrecked ship we encountered just now!"

The picture flashed just now, a small broken wooden fishing boat sank on the bottom of the sea, about a few meters in length and width, half of it was gone, half hidden in the sea sand.

When the propeller heard the order from here, it immediately turned around and drove towards the sunken ship.

Soon, the thruster reached the top of the sunken ship, and the operator immediately started the procedure, and saw two buoys stretched out from under the thruster, connected to the thruster with steel cables and air pipes.

When the buoy reached the sunken ship, two mechanical arms stretched out from the propellers, and began to dig around the sunken ship, digging away the sand, and the buoy also sprayed water, and began to blow the muddy water that had become muddy. clean.

Slowly, the whole picture of the sunken ship was revealed, and the mechanical arm began to pull out the rope to tie up the sunken ship, and then fixed the buoys on both sides of the sunken ship—it can be seen that the fixed position was very precise, just at the stress points on both sides of the sunken ship, There will be no loss of balance when floating.

In order to ensure that the buoys can float the sunken ship safely, three fixed steel pipes extend below the sunken ship between the two buoys to lift the sunken ship, so as to ensure that the sunken ship will not fall apart during the process of floating.

With everything secured, the thrusters began to retrieve the cables.It is obvious that the thruster sinks slightly, and then the power system starts, and it starts to rise slowly!
Soon, the propeller reached the surface of the sea, and then dragged the sunken ship towards the dock!

Although the speed is not fast, it can be seen from the monitor of the thruster that the sunken ship is held firmly by two buoys!

At the dock, many people have not dispersed yet, and some are already waiting anxiously.The originally scheduled test of only half an hour has now passed for 10 minutes, and the thruster has not come back. Some people are worried that the thruster will not be broken, right?

"Here we come!" Someone had sharp eyes and soon saw the propeller slowly coming over the sea.

"Why did it come from the sea? Shouldn't there be a malfunction?"

"That's right, this speed is slow enough. I remember that the publicity said that it can reach seventy or eighty knots underwater? Why is it slow on the sea?"

"What nonsense are you talking about?" Someone already knew the situation, "That's the propeller dragging something! It is said that it was to test the salvage function of the propeller, and a broken fishing boat was caught underwater!"

Can you do this?
