Abstract
Underwater this closed sealed closures for device include one group of ellipse module (2,3,4), their juxtapositions, and internally define at least one volume of holding device in a sealing manner.
Description
Technical field
This patent disclosure relates generally to the underwater closed sealed closures for all kinds device.
Background technology
Some type of industry, such as, it is necessary to submerge electric power or electromechanical assembly in the field of gas or oil exploitation
To very big depth.
Such industry for example needs electric submersible pump (ESP) and their power supply system being immersed into together big
Depth.
In such application, the depth that is reached is up to 3000 meters or even more than 3000 meters.
Immersion system is normally placed in sealing involucrum, to protect their internals from the influence of seawater.
In order to which protection device is from pressure, two kinds of major designs for protecting closed sealing cover be present.
Designed according to the first kind, sealing cover is full of is in pressure balanced non-conductive liquid, typically dielectric oil with sea.It is placed on
Equipment in sealing cover is then subjected to submerge pressure, and must hold in addition with oil phase.Because pressure is balance, so sealing cover
Wall does not suffer from pressure-dependent stress, and therefore need not make it have with the increased thickness of submergence.
According to Second-Order Design, sealing cover is full of the gas (air, nitrogen ...) in the low pressure for being generally near atmospheric pressure.Envelope
The wall of cover is sized to resistance submergence pressure.Then equipment is installed under the conditions of similar to those of industrial use.
The present invention relates to Second Type sealing cover, is referred to as " atmospheric pressure " sealing cover.
Obviously, the pressure that the thickness of sealing cover must must be subjected to according to it, increase with submergence and increase.
Underwater closed sealed closures for device are typically based on the cylindrical involucrum for including two end domes.
For example, for about 3000 meters of submergence, the thickness of cylindrical involucrum can reach 80mm, as a result, right
Be 7 meters in length, interior diameter is 2 meters of involucrum, including its gross mass of the involucrum of equipment for being included can reach 40 tons or
Even more than 40 tons, this needs strong lifting device.
Spherical involucrum also be present, due to their shape so that can considerably reduce in the structure for entering involucrum
Material thickness.
Although producing spherical involucrum to allow to mitigate weight, it has been found that compared with cylinder, such design is collecting
There is the shortcomings that very big into aspect, because spheroid can increase floor space, and therefore cause larger and heavier supporting structure.
In view of foregoing, a kind of sealed closures for being relatively easy to manufacture but weight is lighter than cylindrical involucrum of proposition.
The content of the invention
According to the first aspect of the invention, a kind of underwater closed sealed closures for device are proposed, it includes one group
Oval module, their juxtapositions, and internally define at least one volume of holding device in a sealing manner.
It has been found that compared with cylindrical involucrum, cause gross weight by means of juxtaposition ellipse module production sealed closures
About 1/3rd can be saved.
In one embodiment, sealed closures include being connected to the hemispherical circle in module in groups by sealing flange
Push up the removable end module of shape.
According to a favourable aspect, oval module is connected in pairs by cylinder shape connector.
These cylinder shape connectors can have the thickness of the thickness more than oval module.
In one embodiment, cylinder shape connector is equipped with stiffener element.
For example, these stiffeners are formed by the local increase of cylinder shape connector.
Brief description of the drawings
The following description only provided as non-limiting example is being read simultaneously referring to the drawings after, other mesh of the invention
Mark, feature and advantage will be apparent, wherein：
Fig. 1 is the side view according to the sealed closures of the present invention；And
Fig. 2 is the partial section of the sealing cover from Fig. 1.
Embodiment
With reference first to Fig. 1, it is shown according to the present invention, and for the underwater closed sealed closures of device, it is by Headquarters of the General Staff
Label 1 is examined to indicate.
In this figure, assuming that representing sealed closures on vertical position.
In contemplated application, this sealing cover is intended to protect one or more immersion electric devices or electromechanical assembly, all
Power-supply system such as variable speed drive, low-voltage or high voltage allocation unit, with standby.Certainly, this is not the present invention's
Outside scope, because this sealing cover is intended to receive other types of device.
As seen in Fig. 1, sealing cover 1 includes groups of oval module 2,3 and 4, and quantity is 3 here, they
Setting is in line each other, and is connected in pairs by cylindrical part 5,6 and 7.
In each end, involucrum includes the dome 8 for removing heading shape, and it is connected to one of them in a sealing manner
On oval module, and in relative end, hemispherical dome 9 is connected on another end elliptical module 2.
Oval module and end dome define internal capacity jointly, and internal capacity is full of nitrogen and meaning in atmospheric pressure
Figure receives the device to be submerged.Certainly, the quantity of module does not limit the present invention, and can be according to the total size selecting module of device
Quantity.
In fact, each oval module all has a flat spheroid form, and more particularly by included in such as P1 and
The spherical region of flat spheroid between P2 two parallel planes is formed.
Due to producing the various modules with part spherical in shape, compared with the thickness of cylindrical involucrum, module and end
Portion's dome 8 and 9 has withstand submergence pressure necessary to smaller thickness.For example, for can reach 3000 meters of submergence pressure
Power, therefore the thickness of spherical wall is about 50 mm.
In the case where being related to cylinder shape connector 5 and 6, these parts, which have, to be determined to provide the increased of integral hardness
Thickness, such as about 150 mm.
It will be noted that the diameter of hemispherical dome 9 be less than cylinder shape connector 5,6 and 7 interior diameter, and select be with
Just it is larger than the maximum transverse size of device so that after the opening introducing device via end elliptical module 2, inciting somebody to action
Device is not in problem when being inserted into the remainder of sealing cover.
Therefore hemispherical dome 9 effectively forms removable element, and is fixed to hemispherical module 2 by means of flange 10
On.
Finally see that cylinder shape connector 5,6 and 7 can be provided with stiffener, such as 11 in Fig. 1, stiffener is produced into part
The form of thickened material.But this stiffener 11 is still optional, and show only for one of cylinder shape connector
Stiffener 11 is shown.
Obviously, the sealed closures of one group of juxtaposition ellipse module of just described use so that in oval module
The thickness of opening position sealing cover can greatly reduce.Therefore compared with cylindrical envelope, up to 1/3rd weight can be saved.
