Abstract

用于装置的水下密闭的此密封封罩包括一组椭圆体模块(2,3,4),它们以密封的方式并置,并且在内部界定接纳装置的至少一个容积。

Description

用于装置的水下密闭的密封封罩
技术领域
本发明总体涉及用于各种类型装置的水下密闭的密封封罩。
背景技术
一些类型的行业,例如在气体或石油开采的领域中,需要使电力或机电装置浸没到非常大的深度。
这样的行业例如需要将电动潜水泵(ESP)和它们的电力供电***一起浸没到大的深度。
在此类应用中,所达到的深度可达3000米或者甚至超过3000米。
浸没装置通常放在密封包壳中,以便保护它们的内部构件免受海水的影响。
为了保护装置免受压力,存在两种保护密闭封罩的主要设计。
根据第一类设计,封罩充满与海处于压力平衡的不导电液体,通常是介电油。放在封罩中的装备然后经受浸没压力,而且此外必须与油相容。由于压力是平衡的,所以封罩的壁不会经受与压力有关的应力,并且因此不需要使其具有随浸没深度增加的厚度。
根据第二类设计,封罩充满处于通常接近大气压力的低压的气体(空气、氮…)。封罩的壁大小设置成抵抗浸没压力。然后在类似于工业用途的那些条件下安装装备。
本发明涉及第二类型封罩,称为“大气压力”封罩。
显然,封罩的厚度必须按照它必须经受住的压力,随浸没深度增加而增加。
用于装置的水下密闭的密封封罩通常基于包括两个端部圆顶的圆柱形包壳。
例如,对于大约3000米的浸没深度,圆柱形包壳的厚度可达到80mm,其结果是,对于长度为7米,内直径为2米的包壳,包括它所包含的装备的包壳的总质量可达到40吨或者甚至超过40吨,这需要强有力的提升器件。
还存在球形包壳,由于它们的形状,使得可以相当大地减小进入到包壳的结构中的材料的厚度。
虽然生产球形包壳使得可以减轻重量,但已经发现与圆柱形相比,此类设计在集成方面有很大的缺点,因为球体会增加占地面积,并且因此导致较大且较重的支承结构。
考虑到前述,提出一种较易于制造但重量比圆柱形包壳更轻的密封封罩。
发明内容
根据本发明的第一方面,提出一种用于装置的水下密闭的密封封罩,它包括一组椭圆体模块,它们以密封的方式并置,并且在内部界定接纳装置的至少一个容积。
已经发现,与圆柱形包壳相比,借助于并置椭圆体模块生产密封封罩使得总重量能够节约大约三分之一。
在一个实施例中,密封封罩包括通过密封凸缘连接到所述成组模块上的半球形圆顶形状的可移除端模块。
根据一个有利方面,椭圆体模块通过圆柱形连接器成对连接。
这些圆柱形连接器可具有大于椭圆体模块的厚度的厚度。
在一个实施例中,圆柱形连接器配备有加劲件元件。
例如,这些加劲件由圆柱形连接器的局部增大形成。
附图说明
在阅读仅作为非限制性示例提供的以下描述并参照附图之后,本发明的其它目标、特征和优点将变得明显,其中:
图1是根据本发明的密封封罩的侧视图;以及
图2是来自图1的封罩的局部截面图。
具体实施方式
首先参照图1,它显示了根据本发明,用于装置的水下密闭的密封封罩,它由总参考标号1标明。
在此图中,在假设竖向的位置上表示密封封罩。
在所设想的应用中,此封罩意图保护一个或多个浸没式电力装置或机电装置,诸如可变速驱动器、低电压或高电压分配单元、具有后备的电源***。当然,这不在本发明的范围之外,因为此封罩意图接纳其它类型的装置。
如在图1中看到的那样,封罩1包括成组的椭圆体模块2、3和4,这里数量为3,它们设置彼此成直线,并且通过圆柱形部分5、6和7成对连接。
在各个端部处,包壳包括去顶球体形状的圆顶8,它以密封的方式连接到其中一个椭圆体模块上,而且在相对的端部处,半球形圆顶9连接到另一个端部椭圆体模块2上。
椭圆体模块和端部圆顶共同界定内部容积,内部容积充满处于大气压力的氮且意图接纳要浸没的装置。当然,模块的数量不限制本发明,并且可按照装置的总大小选择模块的数量。
实际上,各个椭圆体模块都具有扁平球体形状,并且更特别地由包含在诸如P1和P2的两个平行平面之间的扁平球体的球形区形成。
由于生产了具有部分球形形状的各种模块,与圆柱形包壳的厚度相比,模块和端部圆顶8和9具有经受住浸没压力所必需的更小的厚度。例如,对于可达到3000米的浸没压力,球形壁的厚度因此为大约50 mm。
在涉及圆柱形连接器5和6的情况下,这些部分具有确定来提供整体硬度的增加的厚度,例如大约150 mm。
将注意到,半球形圆顶9的直径小于圆柱形连接器5、6和7的内直径,并且选择为以便使其大于装置的最大横向尺寸,使得在经由端部椭圆体模块2的开口引入装置之后,在将装置***到封罩的其余部分中时不会出现问题。
因此半球形圆顶9实际上构成可移除元件,并且借助于凸缘10固定到半球形模块2上。
最后在图1中看到圆柱形连接器5、6和7可设有加劲件,诸如11,加劲件生产成局部加厚材料的形式。但是,这种加劲件11仍然是可选的,而且仅针对其中一个圆柱形连接器显示了加劲件11。
显然,刚刚所描述的使用一组并置椭圆体模块的密封封罩,使得在椭圆体模块的位置处封罩的厚度能够大大减小。因此与圆柱形封罩相比,可节约多达三分之一的重量。
