"People breathe between 20 and 40 times per minute during strenuous exercise. We take the average breathing rate of 30 times per minute, which is 1,800 times per hour, and each time we only need
To consume 25 milliliters of oxygen, we need to consume 45,000 milliliters per hour, which is 45 liters of oxygen. This is of course the amount of oxygen we consume during high-intensity exercise on land.
Underwater conditions are different, because under normal circumstances, a twelve-liter cylinder can sustain a diver at ten meters underwater for about an hour.
Of course, this is in a slow or even stationary state. If it is high-intensity exercise, the oxygen consumption will naturally be high. And the oxygen consumption is also related to the water depth. The deeper the water depth, the higher the water pressure, and the more oxygen consumption.
Calculated based on low-intensity exercise ten meters underwater, the oxygen content in one liter of air is 21%, which is 210 milliliters, and the oxygen content in twelve liters of air is 2320
Ten milliliters.
After using our air filtration and oxygen supply circulation system, according to the capacity of a liquid oxygen bottle of twelve liters of liquid oxygen, one hundred and forty-four liters of oxygen can be obtained.
According to the previous standards, two thousand three hundred and twenty milliliters are required per hour, which also means that the liquid oxygen in this cylinder and this system can allow a person to stay underwater for sixty-two hours.
Even if we deduct some losses, we can still stay for more than fifty hours, and this improvement will undoubtedly be huge."
Hearing Zhang Xiaolei's introduction, the scene suddenly became excited, and everyone showed expressions of disbelief. The group of officers and soldiers from the Marine Corps were all extremely excited. They had gained so much this time, and they did not expect that not only could they
They encountered the underwater special warfare mechanical exoskeleton protective armor tailor-made for them, and also saw this air filtration and oxygenation circulation system, a new technological equipment that allows them to stay underwater for fifty or sixty hours.
As people who often dive, they naturally know how long current diving equipment can last underwater.
According to the two cylinders currently issued, one large and one small, there are about twenty liters of air stored in them. Even if they plan carefully underwater and cherish every breath of air, they can only stay there for about an hour and a half. So,
A short time will greatly limit their underwater combat capabilities.
This also allows frogmen to only carry out some special operations tasks in offshore penetration, as well as some special operations tasks such as underwater blasting, underwater mine clearance and underwater salvage.
If they want to conquer the ocean, they must have an air supply system that can allow them to stay underwater for a long time. So for them, their biggest dream is to have a pair of gills like a fish, so that they can be free
are active underwater.
And now, their dream has finally come true, and they finally have these gills.
After giving everyone a little time to digest and react, Zhang Xiaolei continued: "Please see, what is equipped on the back of our underwater special warfare mechanical exoskeleton protective armor is this air filtration and oxygen supply circulation system.
Its size is very small, just like a small diving backpack. According to the function, it mainly consists of several functional modules.
The first is this rectangular module. This is the main body of this air filtration and oxygen supply circulation system, the air filtration system. Through it, we can filter out the carbon dioxide and water vapor in the exhaust gas, and then transport the filtered air to
Oxygen is injected and mixed in the dissolved oxygen device. The mixed air will be sucked into an air tank and stored for our frogmen and divers to breathe."
Zhang Xiaolei pointed to the opened air filtration and oxygen supply circulation system displayed next to the underwater special warfare mechanical exoskeleton protective armor, and introduced the various functional structures inside.
In this air filtration and oxygen supply circulation system, we designed two gas tanks, one large and one small. The larger one is a liquid oxygen tank, which can store twelve liters of liquid oxygen, while the small organ only has two liters.
What is stored is not liquid oxygen, but air.
This small air tank is the backup of the entire system. When the entire air filtration and oxygen supply circulation system fails and cannot be used, the two liters of air in this small air tank can allow our divers to calmly rise out of danger from underwater.
An experienced diver can use these two liters of air to dive underwater for about ten minutes, which is enough for him to troubleshoot and surface calmly.
At this point, Zhang Xiaolei continued to point to the various functional modules inside and introduced: "Here is its battery pack, here is its main control system, etc.
The entire system will monitor the breathing conditions of our divers in real time, as well as the real-time operating status and related data information of each functional module.
And important information will be projected onto the transparent display screen of the glass mask on the protective armor head of this underwater special warfare mechanical exoskeleton, so that our divers can pay attention to this important information at any time.
Some important information, such as the oxygen capacity alarm, will also remind our divers to pay attention through the voice system. The specific standards can be adjusted according to the needs of the user.
For example, when the oxygen capacity in the cylinder is only 10%, an alarm needs to be issued to remind our divers to evacuate and surface quickly."
After listening to Zhang Xiaolei's detailed introduction, everyone present began to believe that this air filtration and oxygen supply circulation system was real.
And as Zhang Xiaolei's introduction progressed, everyone gradually understood the value of this air filtration and oxygenation circulation system.
So after Zhang Xiaolei finished speaking, the colonel Chen Zifang who asked the question immediately asked: "Can this air filtration and oxygen circulation system be equipped on ordinary mechanical exoskeleton protective armor or used alone."
After hearing Chen Zifang's inquiry, everyone became curious. Yes, such a good thing cannot be used just on it. It would be a pity.
Moreover, such a good thing cannot only be made cheap by the navy, they must also be exposed to rain and dew.
Hearing Chen Zifang's words and seeing the reaction of everyone at the scene, a group of Marine Corps officers and soldiers showed indignant expressions. It felt as if these people were bandits who had robbed them of their most precious treasure.
However, in front of these many people, although they were very angry, they did not get angry in front of them. They just showed cannibalistic expressions, as if they wanted to swallow these people at any time.
Facing everyone's different looks, Zhang Xiaolei nodded and said with a smile: "Of course, this equipment can not only be used alone, but can also be equipped on various equipment, including ordinary exoskeleton protective armor, so that they have a certain level of water.
