Chapter 540: Discharge Bomb Disposal Method
This bomb was made temporarily, so we were in a hurry, so many things were replaced, such as this air pressure sensor. A real air pressure sensor is actually a pretty complicated thing, but the thing used on this device is not actually a pressure sensor at all.
This so-called air pressure sensor is actually a gas cylinder similar to a syringe needle, but it has a vacuum inside. Because the oil barrel has always been in a vacuum state, the internal vacuum cylinder will not react in any way. However, once the oil barrel is depressurized, the cylinder will be affected by the external atmospheric pressure, and the external piston will be quickly pressed into the vacuum cylinder. internal. There are two copper plates at the bottom of this vacuum cylinder, and there is a gap between them, so that there is no connection between them, that is, there is no electricity. This state means that the surrounding environment is still a vacuum. The bottom of the piston is covered with a layer of copper sheet. Once the external air pressure is restored, the piston will be pressed into the bottom of the air cylinder, and then the copper sheet will contact the two copper contacts at the bottom of the air cylinder at the same time, so that the circuit is connected. . Once the circuit is connected, the air pressure is restored, and the bomb detonates.
This design is very simple, but it is quite fatal, because the speed of air pressure recovery is very fast, and the piston is super sensitive, so as long as ordinary people open this oil drum, it will inevitably cause an explosion. But now the frost and snow have sealed the top of the oil drum, so even if the lid is opened, air still cannot enter the inside of the oil drum, so the air pressure trigger will not activate. As for removing it...this is the easiest. Just remove the piston.
After the barometer was gone, Shuangxue scanned it again worriedly, confirming that there was only such a barometer, and then removed the ice layer on the surface.
The bomb did not explode after the air pressure was restored because the barometer no longer worked. Now that the shell of the bomb has basically failed, we boldly cut open the entire outer wall of the oil barrel, completely exposing the bomb to us.
It seems intuitive. The structure of this bomb is quite complex, with a very precise pipe structure outside, and these pipes are the main design that prevents you from removing the wires.
The opponent actually stuffed the entire bomb into a set of pipes. In addition to the barometer outside, the inside of the pipe is also filled with something similar to grease. This thing is non-conductive and can shield electromagnetic fields and dissipate heat.
All the lines used by bombs are sealed in this pipe, and the grease filling inside the pipe is the second insurance. Because once we open the pipe, the oil pressure inside the pipe disappears. Without oil pressure, the bomb will be detonated immediately by a trigger device. Therefore, this grease-filled pipe is also an anti-tamper design.
Of course, we don't want to dismantle the pipe, but we want to attack the bomb body directly.
Because the magnetic field shielding device has failed, it is now impossible to completely shield our electromagnetic induction ability by relying solely on the shielding of grease itself. Further internal scanning determined that the bomb's internal detonator was ultimately connected to four batteries.
A modern bomb. As long as it is not ignited and detonated on the spot, it must be electrically detonated. In fact, modern high-end explosives are quite safe. Many military explosives will not detonate even if they are thrown into a fire. An arc generated by a strong current must be used to instantly reach a high temperature of several thousand degrees to detonate such a bomb.
The advantages of this design are many. The biggest advantage is that it is safe and will not explode by itself for no apparent reason. However, their shortcomings are very uniform, that is, they require electric current to detonate.
It doesn't take much electricity to detonate a bomb. A one-dollar coin-sized button battery is enough to detonate the most elementary explosives, and then the tandem detonation method using explosives to detonate explosives can detonate any size of explosives.
The internal structure of this bomb is relatively complex. Therefore, four sets of batteries are used, one of which is the main battery, which is directly a car lead-acid battery. The other three batteries are all the same lithium batteries and appear to have been removed from some kind of remote control. After all, this kind of battery with positive and negative electrodes on one side is a special battery. Not very common.
The solution we thought of to solve this bomb lies in these four batteries.
There are too many protective designs on the bomb. If we crack them one by one, it will take too long. And the enemies around us are not in a daze, they have already begun to attack us. It's just that the electromagnetic barrier formed by Jingjing and Xiao Longnu protects us, so bullets can't threaten us for the time being. But they can't withstand the opponent's attack like this for long. After all, those outside are not miscellaneous soldiers. Their equipment is all very good.
Because we were in a hurry, we needed a simple and direct way to solve this bomb, so the final solution we came up with was to steal electricity.
No matter how complicated the bomb is, it definitely requires electric current to detonate the bomb. Even for nuclear bombs, the initial detonation part requires electricity. There are mechanical nuclear bombs, but at least not this one. What we need to do is to drain all the dischargeable batteries inside this device. As long as the battery is dead, no matter how many detonators we trigger, the bomb will not detonate because there is no current to detonate the bomb.
The reason why we plan to steal electricity instead of cutting the wires short is mainly because there is oil pressure sealing in the series pipes. We cannot cut it faster than the reaction speed of the current, so cutting off the current will inevitably cause the bomb to detonate. In addition, this bomb has several lines. If they cannot be cut off at the same time, there is no guarantee that the bomb will not explode. Even though our dragons are very fast and can synchronize their behaviors, this synchronization is only superficial, and there must be some subtle differences. These wires must be cut off simultaneously to ensure that the bomb will not detonate, and the error interval cannot be less than the time it takes for the current in the circuit inside the bomb to complete the entire circuit. The speed of electricity is the same as the speed of light. The total length of the wires in this bomb plus one piece will not exceed one hundred meters. Imagine how long it takes for the current to travel this distance. We obviously can't cut off all the lines at the same time in such a small amount of time, so this method is not feasible.
However, synchronized power reduction is not possible, but electricity theft is.
There is no voltage detection system in this bomb, so if we discharge the battery, the bomb itself will not react when the voltage gradually drops. When the voltage drops to the point where the voltage stabilizing capacitor can no longer maintain a stable voltage output, the bomb will detonate. It is indeed possible for the device to connect the detonation line, but by then the remaining power in the battery will not be enough to detonate the bomb anyway. In this way, the bomb is completely useless. (To be continued ~^~)
