Open an aircraft carrier to fight against Japan

The duty officer hurriedly said: "There are already rescuers going down."

Zhang Yi said angrily: "How long has it been going down? Why hasn't the Master been rescued yet?"

The duty officer said with a face of shame: "This rescue has indeed encountered difficulties."

Zhang Yi quickly said, "What difficulties did you encounter?"

The officer-in-charge said: "Because of the large amount of landfall, the exit is tightly blocked, and it is absolutely impossible to dig by manpower. There is only one way, and that is to use explosives to blow up a hole and rescue people from it." .”

Zhang Yi asked, "Then why haven't you heard the explosion?"

The duty officer said worriedly: "We heard from the miners who ran up that the top of No. In one place, if there are too many explosions, the roof of the No.13 slot is likely to collapse, and at that time, none of the miners inside will be able to survive.”

Zhang Yi said: "Then blast where the miners are, and rescue them directly from there!"

The duty officer said helplessly: "This is where the difficulty lies. We can't determine where they are trapped?"

Zhang Yi said, "Wouldn't they be knocking on stones below to make a sound?"

The officer on duty shook his head again and said, "Then the location we got is only accurate, and there is no way to rescue them."

Zhang Yi slapped his thigh anxiously, and said, "This will not work, and that will not work, won't they just die down there!"

Lin Yuan asked at this time: "Are these thirty or so miners all together?"

The officer-in-charge said: "They are a team, and logically speaking, they will not disperse."

Lin Yuan asked: "Then where did they go down, don't you have a record?"

The duty officer shook his head and said: "There is no record. We only record the daily coal production. The miners' descending locations are never recorded."

Lin Yuan thought for a while and said, "Come on, let's go down and have a look."

The officer on duty quickly said: "My lord can't do it, you are the body of a thousand gold, just in case..."

Lin Yuan smiled and said: "I still have some understanding of the structure of the mine, but one trough collapsed, and the main shaft and horizontal roadway will definitely be fine. If there is danger, the rescue team will not dare to go down."

When the mine is excavated, first a vertical main shaft and a vertical auxiliary shaft are dug downward from the ground. Fresh air is sent into the mine from the auxiliary shaft. After digging to a certain position, digging in the horizontal direction The horizontal roadway, after digging to the predetermined position, goes up, and then reaches the coal seam, and then excavates the mining face along the horizontal and vertical directions in the coal seam, which was called "trough" in the Qing Dynasty. Above this layer, there will be The channel leading to the ground is dug into the air return port. The wind enters from the air supply port and flows out from the return air port, thus ensuring the breathing needs of the miners.

Lin Yuan and the others took the cable car down to the horizontal main road of the mine, and then came to the No. 14 trough. There were more than a dozen miners carrying cartridges on the trough, discussing countermeasures.

Lin Yuan looked at the gravel on the ground and thought of a way.

Lin Yuan frowned and said to Zhang Yi: "Master Zhang, I don't know how you should explain to the court when something like this happened?"

Zhang Yi didn't know how to answer, he was so anxious that cold sweat dripped from his forehead, Lin Yuan sneered and said, "Master Zhang, if I get through this disaster for you, how can you thank me?"

Zhang Yi quickly said: "Kaiping Coal Mine, 5.00% of the shares, hand over!"

Lin Yuan smiled and said, "I don't want your shares, I just want you to send the best quality coal to our Machinery Bureau!"

Zhang Yi nodded vigorously, and said, "It must be, Mr. Lin, what can you do?"

Lin Yuan said: "You tell the irrelevant people to leave immediately, I will bring a strange person later, he has a way to find the miners below!"

Zhang Yi looked at Lin Yuan puzzled, and asked, "Is what you said true?"

Lin Yuan nodded and said without a doubt: "Of course it is true, let's go, let's go up."

Lin Yuan led them back to the ground, and he asked, "Is there any open space near here?"

The officer on duty quickly said: "Just three miles to the east, there is a large open space."

Lin Yuan nodded and said, "Very well, pass on an order that no one is allowed to go to that open space." After Lin Yuan finished speaking, he left without looking back.

He came to the open space, turned on the communicator, and got in touch with the Beijing ship. He found Yang Yu of the pilot unit and said, "You send an experienced non-commissioned officer with that set of all-angle flexible detection equipment to come to me. Here, hurry up!"

An hour and a half later, a helicopter landed in the open space, and a middle-aged man got off the helicopter, still carrying a large box in his hand.

Lin Yuan hurried up to meet him, and said with a smile, "Old Wei, why are you here?"

Old Wei smiled and said: "Captain, don't you need an experienced non-commissioned officer? They sent me here. To be honest, I really didn't expect that I, a veteran of aero-engine repair, would come in handy at this time. "

Lin Yuan glanced at the box in his hand and asked, "Is this the all-angle flexible detector?"

Old Wei said: "Yes, but we prefer to call it a robot snake. Haven't you seen it? It moves exactly like a snake."

The aero engine is a gas turbine engine. This type of engine has two key components, the compressor and the turbine. It is still a high-temperature and high-pressure environment, so the thermal load and gas force load of the blade are very large, so that cracks will appear on the blade after a certain period of use, which requires special personnel to inspect it after each flight. "

It is impossible to disassemble the engine during the inspection, so it is necessary to enter the inside of the engine for inspection. For the al-31 engine, observation ports are opened on the casings where the compressors at all levels are located, so as to observe the condition of the blades. In fact, the observation device is this kind of robot snake.

To put it bluntly, this kind of robotic snake is a long rod with a high-definition camera at the front end, but due to the special design, this long rod can be bent arbitrarily like a snake, and it can pass through the gap between the inlet guide blades of the aero-engine Drill in and check the blades at all levels in turn.

Old Wei followed Lin Yuan to the outside of the main well. Due to Lin Yuan's special instructions, Old Wei not only did not wear a military uniform, but also wore a robe of this era.

Lin Yuan took Lao Wei and a guide to the No.14 slot. After Lao Wei arrived, he took out the robot snake and turned on a laptop. The video of the robot snake camera was transmitted to the laptop through Bluetooth technology. .

Old Wei manipulated the robotic snake, and it was really like a spirit snake, and got into the gap of the falling rock. The robotic snake transmitted the video signal back to Lao Wei's computer, and it was clear that the robotic snake was drilling through the rock. gap.

Lin Yuan asked: "Can you go down to the trough below?"

Old Wei said: "Didn't they say it just now? There is a gap below, so there should be no problem."

At this time, the screen suddenly opened up. It was obvious that the robot snake had passed through the gap and entered the No.13 slot. Lin Yuan asked, "Will your robot snake not fall to the ground?"

Old Wei smiled and said, "This robot snake has a fixed mechanism, and it's not heavy, so it can hang on the wall and move forward."

Just then, a blurry light appeared on the screen.
