Fan Keqin continued: "So it is very necessary to be vigilant at all times. How about it? Have you completed the secret code check? Have you been touched?"
Jiang Bin and Du Shengli did not answer immediately, but squatted down and continued to look at a certain place on the ground. After careful identification, the two people looked at each other and nodded at the same time. He stood up and said, "Virgo, no one has touched you."
"Okay." Fan Keqin said, "Let's see what the experimental results are."
Hearing this, Jiang Bin and Du Shengli first looked through the water at the four timers, then fished them out and looked at them again. Jiang Bin took one of the pieces and said: "Record, no abnormality such as water accumulation inside the timer No. 1 was found." Then he looked at his watch again, then looked at the time inside the timer, and continued : "There is no problem in operation, the deviation is about half a minute, but considering that there is a certain error tolerance rate, it is normal."
While he was talking, Du Shengli held a small notebook next to him and began to write down bits and pieces of records.
Jiang Bin put down timer No. 1, picked up the one next to him, looked at it again, and said: "Timer No. 2, there is water leakage inside." Then he looked at his watch again and continued: "But from now on It has been in the water for more than eight hours. Up to this point, the operation is normal, with a deviation rate of one minute to two minutes, and the error tolerance rate is still within the normal range..."
Jiang Bin, one observing and the other recording, quickly completed the experimental steps using four mechanical timers for the water seepage test. The final result was that no water leakage was observed in one of the timing devices. There were three remaining timers, two of which were filled with water. Fog can already be seen inside one. In other words, water leakage occurred in three-quarters of the timers.
However, after being soaked in water for eight hours, although there was a high level of water accumulation, all four timing devices operated normally.
In fact, the main reason for this is that the time is still short, and these timing devices are all mechanical. Although there is water inside, it is unlikely that malfunctions such as rust will occur immediately. This requires a process, so the final experimental results show that there is no problem with the timing effect of these mechanical timing devices for at least eight hours.
Fan Keqin said: "This is a water basin. Considering the actual needs, we might be in sea water at that time, and it was about three meters deep, which is completely different from now. So I personally suggest that you go inside the river Also do an experiment. At least the depth and so on can meet the requirements. Get as close to the actual bad environment as possible and see how long these timers can still operate normally."
Du Shengli said: "Yes, we will conduct this experiment today."
Fan Keqin nodded and asked: "Where are those mines? What's going on?"
Du Shengli replied: "In addition to the original charging department, there are four water injection chambers, and Brother Jiang and I placed TNT ladders. After entering the water, we measured it. When the mine snorkeling returned to zero, it was directly 1.5 meters underwater. About. So Brother Jiang and I adjusted the depth setting device repeatedly in detail, and finally found that when the depth setting was at two meters, the actual depth was three meters below the water surface."
Jiang Bin added next to him: "For the sake of accuracy, we also used four mines and did the same experiment on a deeper section of the river. Indeed, just as Shengli said, after the four cabins were directly installed on the TNT , when the fixed depth is two meters, the actual situation is snorkeling about three meters below the water surface. This cannot be wrong.”
Fan Keqin said: "Very good, this is very important." After saying that, he thought for a moment and then said: "Have you studied the mine triggering device?"
Jiang Bin nodded and said: "We have studied it. The device that triggers the mine is similar to the firing pin. Just destroy the internal linkage rod. It's just that there are a lot of trigger devices for the mine, so it's more troublesome to destroy it. It’s just stupid work.”
"Well." Fan Keqin said: "Okay, in a few days, I will find some brothers with strong diving abilities to come over, and you have to teach them how to use mines. As you just said, isn't the timing device double insurance? Yes. Teach them step by step how to set the time. And they still need practice, so you'd better dismantle the charging part of a mine, detonators, etc. At that time, I will arrange for them to conduct special training in the water."
"Understood." Du Shengli stood up and said, "These are not complicated and can be done quickly."
Fan Keqin said: "Okay, you can continue."
Next, Fan Keqin watched the two people working here again. They also used double insurance for the detonators in the mines. In this way, if one of the detonation systems fails, the other detonation system can also ensure that TNT explodes.
After watching for about an hour and nearly two o'clock, Fan Keqin couldn't stay here all the time, so he went out directly, took his bodyguard with him, and drove back to the security bureau.
Zhuang Xiaoman followed him into the office, put the document bag on the table, and said: "Virgin, all team leaders and captains moved very quickly. According to your request yesterday, all the names have been reported."
Fan Keqin said: "Okay, let me take a look first."
After Zhuang Xiaoman went out, Fan Keqin took out the list from the document bag and started to read it. This list is not just one name and done with it. How good your water quality is, how many meters you can dive, and how long you can hold your breath underwater must all be reflected.
Fan Keqin finally selected the twelve ones with the best water properties. Then he looked at another list, this one with more people, all of whom were newly added to the field team and investigation office in the past half month.
The reason why Fan Keqin wants to use a large number of new people this time is because these people are all new faces, especially to Guangzhou, they must be new faces. These people Fan Keqin still have to be used as an insurance, and these need to be temporarily commanded. If everything goes well, they will not even be needed. But Fan Keqin couldn't let them do nothing there, just travel.
Fan Keqin looked at the list in detail and selected twelve people again. So the people who had been selected previously and had the best water quality got together. He looked at it again, then reached out and pressed the buzzer, saying: "Xiaoman, come in."
After Zhuang Xiaoman came in, Fan Keqin handed her the list and said, "These people are once again asked to be investigated secretly and quickly by each team leader, and each team leader is asked to report to me individually after the investigation."
