Specific embodiment
Structure, ratio, size depicted in Figure of description etc., are only used to coordinate the content disclosed in specification, with
Understand and read for those skilled in the art, be not limited to the enforceable qualifications of the utility model, therefore do not have skill
Essential meaning in art, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influenceing the utility model institute
Under effect of energy generation and the purpose to be reached, all should still fall what is covered in the technology contents disclosed in the utility model
In the range of.Meanwhile, in this specification it is cited such as " on ", D score, "front", "rear", " centre " term, be merely convenient to chat
That states understands, and is not used to limit the enforceable scope of the utility model, and its relativeness is altered or modified, without substantive change
Under more technology contents, when being also considered as the enforceable category of the utility model.
As shown in Figure 1-Figure 3, the utility model is a kind of low pressure cabin structure, and it includes nacelle 1, and the inside of nacelle 1 is cabin
11, the two ends of the nacelle 1 are provided with end plate, and one of end plate is provided with hatch door 12.The nacelle 1 is provided with the He of air inlet 21
Exhaust outlet 22, the exhaust outlet 21 is connected by pipeline with vavuum pump 3, and the nacelle 1 is provided with pressure sensor 4, the pressure
The measuring head of force snesor 4 is stretched into cabin, and the vavuum pump 3 and pressure sensor 4 are electrically connected with a controller 5.It is described
The interior top in cabin 11 or side wall are provided with least one main fan 61, can be dispelled the gas in cabin 11 by main fan 61 mixed
Close, it is to avoid the gas pressure of the position of air inlet 21 is excessive, oxygen concentration is too high, and the gas pressure of the position of exhaust outlet 22 it is too small,
The too low problem of oxygen concentration, the gas allowed in cabin 11 is more uniformly distributed, and keeps a good use state.
As shown in Fig. 2 in the present embodiment, the main fan 61 is provided with one and is arranged on the interposition pushed up in cabin
Put.Additionally, the position of the air inlet 21 is provided with the auxiliary blower 62 installed in cabin side wall.To be entered by auxiliary blower 62
The air for entering cabin 11 is dispelled rapidly, coordinates the air allowed in cabin 11 to be sufficiently mixed with main fan 61 so that cabin 11 is everywhere
Gas pressure and oxygen concentration reach unanimity respectively.
In the present embodiment, by verification experimental verification, it is diagonal that the air inlet 21 and exhaust outlet 22 are separately positioned on cabin 11
During the position at line two ends, working effect preferably, i.e., can improve the speed air flow in cabin 11, so as to allow the gas in cabin 11
Body pressure stability, and oxygen concentration is evenly distributed.In other embodiments, air inlet 21 and exhaust outlet 22 relative can also set
Put.
With reference to Fig. 1-Fig. 3, operation principle of the present utility model is as follows：
Pre-set on controller 5 according to the height above sea level to be reached first, then user enters into cabin
In room 11 and hatch door 12 is shut, hereafter vavuum pump 3 is started working, and cabin 11 is vacuumized, and gas is discharged from exhaust outlet 22
Cabin 11.In vacuum, the gas pressure in cabin 11 is gradually reduced, oxygen concentration is gradually reduced, default when reaching
During height above sea level, air inlet 21 is in communication with the outside, and outside air is entered into cabin 11, to supplemental oxygen in cabin 11.And with
Outside air into cabin 11, the gas pressure in cabin 11 can be improved, in order to keep at the gas pressure value in cabin 11
In stable state, default height above sea level is kept, the vavuum pump 3 is constantly in working condition and carries out work(according to actual conditions
Rate is adjusted, i.e.,：Gas pressure in the real-time detection cabin 11 of pressure sensor 4 and by electric signal input controller 5, controller 5
The watt level of vavuum pump 3 is adjusted after treatment, and then causes that the air inflow in cabin 11 is equal to capacity, it is ensured that cabin 11
Gas pressure stabilization.And in order to ensure the accuracy of detection of pressure sensor 4, main fan 61 and auxiliary blower 62 are also always on,
Gas in cabin 11 is fully dispelled into mixing, makes the gas pressure value region of diverse location consistent；Finally, cabin 11 is being ensured
While gas pressure stabilization, it is ensured that oxygen concentration, it is to avoid user's anoxic, for user provides a safe and reliable use
Environment.
In sum, a kind of low pressure cabin structure of the utility model, can solve the problem that gas pressure detection in the cabin of hypobaric chamber
Precision is not high, easily causes the problem of anoxic.So, the utility model effectively overcomes some practical problems of the prior art
