Description

进水管
本申请是中国专利申请No.200480007049.4(国际申请日：2004年3月22日；国际申请号：PCT/EP2004/050345；发明名称：进水管)的分案申请。
技术领域
本发明涉及进水管。这种进水管被应用在船上，以便向热交换器提供冷却水。具体地，这种进水管用在安装液化天然气设备的船上。在本说明书和权利要求中，所述船指轮船、驳船、浮动平台等。
背景技术
在R Franciss的文章中对这种进水管的一个实例进行了描述，该文章“对Albacora油地的Petrobras PXXV平台的海水起重外壳最大应力模型试验”发表在1995年9月第9届海上工程国际学术研讨会上。此篇文章阐述了安装进水管的浮动离岸平台，进水管可以用铰链连接到平台的浸没潜水箱。
发明内容
本发明的目的是提供一种设计简单可靠的进水管。
按照本发明，提供了一种可以悬挂于船的进水管，进水管包括一个连接到立管悬挂器的立管，立管悬挂器包括第一管形元件，与立管相连的第二管形元件，一个连接第一和第二管形元件的柔性载荷传递元件，一根端部固定在两个管形元件的邻近端的软管。
本发明还涉及安装有进水管的船。
附图说明
本发明将参考附图通过实例加以说明，附图中
图1示意性地显示按照本发明的进水管不按比例的局部纵剖面图；
图2显示沿图1的II-II线的截面图；
图3示意性地显示按照设有三个本发明的进水管的船底部未按比例的横截面图；
图4示意性地显示图3中部分IV的放大比例的详图。
具体实施方式
现在参考图1，图1示意性地但不是按比例地示出本发明的进水管1。进水管1悬挂在船身2上(图中未显示)。进水管1包括一个连接到立管悬挂器4的细长管3。立管悬挂器4包括两个管形元件，第一管形元件6和第二管形元件7。第一管形元件6的上端有一个设有悬挂凸缘8的开口端。悬挂凸缘8与船身2中形成的合适开口10匹配，这样第一管形元件6支撑在开口10中，因此被固定到船上。将第一管形元件6固定在船上(图中未显示)允许进水管1悬挂在船身2上。
立管悬挂器4还包括第二管形元件7。细长管3的上端用合适的装置连接到第二管形元件7的下端。图1中连接部分的直径比开口10的直径大。然而，适合地，选择开口10的直径使得进水管能够放下穿过开口，直到悬挂凸缘8在开口10中受到支撑。
立管悬挂器4还包括一个连接第一和第二管形元件6和7的柔性载荷传递元件16。在图1所示的实施例中，柔性载荷传递元件16是一根链。立管悬挂器4还包括一根两端被固定在第一和第二管形元件6，7的邻近的端部19和20的软管17。软管17以密封的方式固定在端部19和20上。
合理地，每个管形元件6和7设有十字形内部零件22(参见图2)，内部零件22具有用于将柔性载荷传递元件固定在内部零件22上的装置23。十字形内部零件22被合适地焊接到管式元件6和7的内表面。为了简化图中未显示焊缝。
在本发明的进水管1中，软管17形成水的通道，而柔性载荷传递元件16将自重和细长管3的动态载荷传递给第一管形元件6。用这种方法将输送水的功能与传递载荷的功能分离。
现在参见图3。图3显示船30的底部至少设有两个进水管。在这种情况下，船30设有3个按照本发明的进水管，其中第一管形元件(图中未显示)被固定在船30上，并被悬挂于船身2上，如图1中更细致地说明。
为了防止进水管1碰撞，至少设有一个立管隔套35。进水管1的动态响应将决定立管隔套35的数目和位置。图3中仅显示了一个立管隔套35。
立管隔套35包括相互连接的导向套管36，一个导向套管36对应一个进水管1。杆37形成互联件。每个导向套管36限定一个管孔40(参见图4)，管孔40允许细长管3自由穿过，并且允许细长管3绕水平轴线43旋转。水平轴线43是一根位于立管隔套35对称面的轴线，该平面与穿过管孔40通道的方向垂直。
立管隔套35从船30悬下一个预先设定的深度。在图3所示的实施例中，立管隔套35借助一根固定在船身2中的缆索45悬挂着。在另一个实施例中，用链条代替缆索45，或者其中一个导向套管固定到进水管上。
导向套管的长度优选地是立管外径的一到四倍。将立管隔套的导向套管36相互连接的杆37可以用框架或实心多边形代替。实心多边形的厚度优选地在立管直径的三到四倍之间，以防止进水管的涡流尾迹。
进水管1的开口上端开口进入船30内侧的储器46，从储器中抽水(图中未显示)以用作冷却水。
优选地，进水管的数目是两到八个。
