Description
Technical field
The utility model relates to rebreather fields, and in particular to a kind of underwater free respiratory system.
Background technique
With the improvement of living standards, more and more people like underwater swimming, therefore rebreather is in order to meet people's demand
And Ying Sheng.There are mainly two types of present rebreather, when superficial diving when (in usually 0.5m, it is commonly referred to as superficial or
Floating swimming), it is mostly the diving mask with respiratory siphon, respiratory siphon limited length can only be for the of short duration diving of people, when can not be long in water
Between for people breathe.When diving under water deeper (usually 4-5m), generally uses pumped air or use artificial oxygen cylinder and respiratory regulation
Equipment, whole cost of equipping is high, is not suitable for ordinary people.Therefore, there is a kind of floatation type underwater respiring system, the structure
Mainly air inlet pipe is difficult to articulate through floating material on the water surface by gas pipeline or connection, with oral inhalation, with nasal cavity by people
Body exhaust gas is directly discharged in water.Additional gas is not done by breathing mask to be pressurized to atmosphere discharge, and floating material air inlet
Mouthful get too close to the water surface, since the water surface has wave generation, easily make water flow backward enter gas pipeline or barrier natural air into
Enter admission line or once flow back into breathing mask, will lead to underwater personnel and choke water, most probably direct life-threatening；
And since characteristics of contaminated respiratory droplets exhaust gas does not do pressurized treatment, it is easy to flow backward ponding again in exhaust pipe, discarded to be trapped in air-exchanging chamber, nothing
Method is thoroughly discharged in atmosphere, is flowed back into breathing mask, and underwater personnel is caused to suck the exhaust gas oneself being discharged in vivo, pole repeatedly
Yi Yin is poisoned and shock of fainting.This is extremely hazardous under water.
Former device is reviewed again, equally exists problems: when diving arrives certain depth, being passed through to be difficult to articulate and is practiced port chamber
The mouth of air-breathing, related personnel is occupied, and simultaneously non-human uses the normality mode of nose, must carry out corresponding abundant
Training can be grasped.Further, it is exhausted directly in water by nasal cavity by discarded, bubble is generated in water, due to waterproofing design
It is too simple, only used a tarpaulin, and only carried out a water-proofing treatment, when wave is excessive, water be very easy into
Enter in guide pipeline and respirator, though also easily cause underwater personnel to choke water by mouth breathing.And enter air guide since water flows backward
Pipeline causes ponding, even if not entering respirator, since water has barrier action to outside air, underwater personnel still can not inhale
The outside air on the water surface is got, people is caused not dive under water for a long time, it is still necessary to which emerge ventilation, and the pre- of the device is provided as
It is played with actually having no way of.
Utility model content
Problem to be solved in the utility model is to provide a kind of adaptation people and dives under water for a long time under water, prevents water from entering breathing

Convenient to stretch under water for telescoping tube, land is withdrawn.In addition, the lower end of the floating frame 2 can be equipped with band, in this way
People can drive floating frame in water surface movable in diving by band.
Operational process shows that gas flowing forms completely closing back by multiple water-proofing treatment in the entire system
Road, to ensure the life security of underwater operation personnel.
In addition, having liberated mouth, and because have gas in mask because can freely breathe by nose in diving mask
Body meets Acoustic Wave Propagation condition, so can easily, conveniently be conversed with companion by language by installing wireless device additional.
In addition, position of exposing the surface, can choose and coat cheating colouration, meanwhile, gas will not be generated in respiratory in water
Bubble, convenient in investigation game, concealment is swum across.
Underwater free respiratory system specific work process described in the utility model is as follows:
People takes diving mask and dives beneath the water, and floating frame is immersed in the water, under floating air-bag effect will not submerged, the
One air inlet pipe and downtake pipe expose the surface, and fresh air is through the first air inlet pipe, the 52, second air inlet pipe, 53, third air inlet pipe
Accelerate fresh air to enter diving mask through flexible gas-guide tube in the effect of suction fan into inlet chamber, breathed for people, exhalation
Exhaust gas enter another gas-guide tube, exhaust fan effect under, exhaust gas accelerates into discharge chamber, through third exhaust pipe, second row
Tracheae, downtake pipe are discharged in atmosphere.Operational process shows that gas flowing is formd in the entire system by multiple waterproof
The complete loop of processing, to ensure the life security of underwater operation personnel.
During this, if having once in a while water enter first into (row) intratracheally, water will directly pass through drift under the effect of gravity
The branch pipe of scaffold flows back in water, water will not be allowed to enter the respiratory system.The underwater free respiratory system air circulation is quick, more suitable
People's diving is closed to play, meanwhile, bubble will not be generated in respiratory in water, invisible height improves enjoyment.
