Description
Technical field
It the utility model is related to deep-sea pressure-bearing cabin technical field, specifically a kind of deep-sea pressure-bearing cabin.
Background technology
Pressure-bearing cabin is the important component of marine electromagnetic survey system, and electronic equipment usually requires to be sealed in pressure-bearing cabin
It is interior.The gas of usual pressure-bearing cabin filling is air, because the thermal conductivity of air is general and contains more moisture, particularly in sea
Opened the cabin on side or ship maintenance when, the moisture and salinity in air are very big so that heat caused by electronic device in pressure-bearing cabin
Nacelle can not be delivered to readily through heat-conduction effect and moisture contained therein and salt branch are influenceing electronic component just
Often work, heat dissipation problem when relatively high power heat generating components is particularly provided with pressure-bearing cabin in pressure-bearing cabin just seem particularly heavy
Will, the method for existing deep-sea pressure-bearing cabin filling gas is typically to use nitrogen displacement, but the thermal conductivity factor of nitrogen and air
Thermal conductivity factor be more or less the same, it is impossible to meet the requirement of pressure-bearing cabin internal heat generation part heat dispersion；It is for the foregoing reasons, it is necessary to right
The method of existing deep-sea pressure-bearing cabin filling gas carries out technological improvement.
Utility model content
The purpose of this utility model is to provide a kind of pressure-bearing cabin, caused with solving filling air in pressure-bearing cabin in pressure-bearing cabin
Heat caused by component can not disperse rapidly and pressure-bearing cabin in metal component it is oxidizable the problems such as.
To achieve the above object, the utility model provides following technical scheme：
A kind of pressure-bearing cabin, the one end in pressure-bearing cabin set one or more inflatable interfaces, and one of inflatable interface is with filling
Tracheae connects；The pressure-bearing cabin seal plug of sealing is provided at the inflatable interface of pressure-bearing cabin.
As further program of the utility model：The pressure-bearing cabin is arranged to cylinder, a cross face of cylinder
It is upper that one or more inflatable interfaces are set.
As the utility model further scheme：One end that the pressure-bearing cabin is connected with gas tube is set down.
As the utility model further scheme：Vacuumized in the pressure-bearing cabin under unused state, use state
Lower filling helium.
The method of pressure-bearing cabin inflatable body, comprises the following steps：
1) one end in pressure-bearing cabin sets one or more inflatable interfaces, and one of inflatable interface connects with gas tube
Connect；
2) helium is filled into pressure-bearing cabin by gas tube；It will be vacuumized in advance in pressure-bearing cabin before filling helium；Fill helium
Pressure-bearing cabin is inverted during gas, one end that pressure-bearing cabin is connected with gas tube is down；
3) after inflating, inflatable interface is pulled out, with pressure-bearing cabin seal plug seal and pressure bearing cabin inflatable interface.
As further program of the utility model：The pressure-bearing cabin is arranged to cylinder, a cross face of cylinder
It is upper that one or more inflatable interfaces are set.
Compared with prior art, the beneficial effects of the utility model are：In the utility model, filling helium can make pressure-bearing
Heat disperses rapidly caused by component in cabin, improves the heat conductivility in pressure-bearing cabin, is being advantageous in pressure-bearing cabin component just
Often work；The device in pressure-bearing cabin can be prevented to be corroded, be advantageous to improve the stability of circuit in pressure-bearing cabin；With inversion pressure-bearing
The method that helium is filled in cabin or vacuumize in advance can effectively discharge air in pressure-bearing cabin, overcharge helium and ensure that and fully drain
Air in pressure-bearing cabin, improve the purity of helium in pressure-bearing cabin；Pressure-bearing can be prevented with pressure-bearing cabin seal plug seal and pressure bearing cabin
Cabin seawater in deep ocean work enters pressure-bearing cabin；This method effectively raises the stability of system operation, makes the use of system
Life-span is longer.

Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
Embodiment 1
Fig. 1-2 is referred to, component is fixed in pressure-bearing cabin 1, an inflatable interface 2 is arranged on the one of pressure-bearing cabin 1
End, a gas tube 3 and any one inflatable interface 2 are linked together, make the end face court of pressure-bearing cabin connection gas tube 3
Under, the air-tightness in pressure-bearing cabin is checked, carries out the preparation before inflation；Filling air is substituted with filling helium, by common finished product business
It is filled with canned helium by the gas tube 3 connected and an inflatable interface 2 in pressure-bearing cabin 1；Because the density of helium
Smaller than the density of air, the air in pressure-bearing cabin 1 will be in the inflatable interface 2 that the bottom of pressure-bearing cabin 1 does not connect gas tube 3
Face is come by helium ejection；Improve the purity of helium in pressure-bearing cabin during filling gas using the method overcharged into pressure-bearing cabin 1；Fill
With pressure-bearing cabin seal plug sealing inflatable interface after complete helium, prevent seawater from entering pressure-bearing cabin；Inverted pressure-bearing cabin level is put
Put.
Embodiment 2
Fig. 1-2 is referred to, component is fixed in pressure-bearing cabin 1, all inflatable interfaces 2 are arranged on the one of pressure-bearing cabin 1
End, a gas tube 3 and an inflatable interface 2 are linked together, check the air-tightness in pressure-bearing cabin, carry out the standard before inflation
It is standby；Inflatable interface 2 on connecting pipe on vacuum air pump and pressure-bearing cabin end face is closely connected, opens vacuum air pump
On vacuum valve, the air in pressure-bearing cabin 1 is extracted out, makes to close vacuum valve after forming vacuum environment in pressure-bearing cabin 1；Will be general
The logical commercial canned helium of finished product is filled with pressure-bearing cabin 1 by the gas tube 3 connected and an inflatable interface 2；To pressure-bearing
Helium is overcharged in cabin, helium is overcharged and ensures to fill the purity of helium；Connect after charging helium with the sealing inflation of pressure-bearing cabin seal plug 4
Mouthful, prevent seawater from entering pressure-bearing cabin.
