Abstract

一种波泵装置(1)，包括连接至浮筒(4，50)的泵部分(2)，其中所述泵部分(2)还连接至至少一个潜水浮锚(12)。

Description

波泵装置
技术领域
本发明涉及一种波泵(wave pump)。更具体地，本发明涉及这样一种波泵，其包括连接至潜水泵的浮筒(pontoon)，其中至少一个浮锚(wateranchor)防止所述潜水泵跟随所述浮筒进行垂直运动。
背景技术
现有技术中已知有数种水波泵的方案。被大量采用的一个实施例是一种被夹在海水表面上的浮筒与海床或者可选地位于海床上的重物之间的泵。实际情况中所述泵可以位于浮筒中或者海床上并通过绳索分别连接至海床或者浮筒。
这种类型的水波泵通常用于驱动连接至发电机的涡轮以用于发电。
适用于在商业基础上能量提取的巨大波浪通常在相对较深的近海中产生。因此，上述类型的漂浮波泵必须通过相对较长的绳索连接至海床。
由于实际存在的原因，将泵自身定位在海床上是不明智的，特别是在海水深度较大、泵相对较大和当泵需要被连接至共用的叶轮机装置时更是如此。这种方案需要到达海面的相对较长和承受高压的绳索，并且也使得维护和检查工作变得复杂。
发明内容
本发明的目的是改善或者减小现有技术中的至少一个缺陷。
通过下面的说明书以及权利要求书中阐述的技术特征，本发明可以实现上述目的。
根据本发明的波泵包括连接至浮筒的泵部分，所述泵部分还连接至至少一个潜水浮锚。
优选地，所述潜水浮锚还设有至少一个翼片(flap)，所述翼片被设置为当所述潜水浮锚沉入水中时打开以使水流过。
优选地，所述潜水浮锚的形状为倒金字塔形，可以是金字塔的平截头体，金字塔的“顶部”面朝下。
在优选实施方式中，所述泵部分浸没在水中并与所述潜水浮锚装配在一起。优选地，所述潜水浮锚位于波浪力量产生的影响很小的深度。
所述泵部分通常包括导管和泵管，所述泵管可滑动地密封所述导管并且所述泵管连接至所述浮筒。所述导管还连接至其各自的止回阀(checkvalve)，使得当所述泵管从所述导管向外移动时水能够流入所述泵管中。当所述泵管沿着所述导管在其中移动时，水从所述泵管流出并流入所述导管，然后通过所述泵出口流出。
更优选地，所述浮筒设计为细长体，所述细长体的一个端部连接至所述泵部分。所述浮筒的相对的端部设有平衡配重(counterweight)。
优选地，所述浮筒具有三角形纵截面，其中所述三角形中的一个角面朝下。
根据本发明的浮筒由于其结构的原因将比相应的传统浮筒移动到波谷更深处。其原因是，所述浮筒的平衡配重位于沿着波浪更高的位置，能够向波谷更深地浮动，而同时，与所述泵连接的所述浮筒的端部的浮力还没有来得及将所述水波泵拉到足够高的地方。
同样的方式，与所述泵连接的所述浮筒的端部将升起在所述波浪的波峰之上，这是因为所述平衡配重通过波浪顶部与底部之间的平衡力将所述端部抛出水面。
因此，与采用现有技术的浮筒相比，可以极大地增加用于所述泵的底部和顶部位置的浮筒连接点之间的有效高度。在下面的具体实施方式部分将对所述细长浮筒的工作原理进行更详细的说明。
附图说明
下面参照附图描述本发明的非限制性的实施例，在附图中：
图1是根据本发明的水波泵的侧视图；
图2是图1所示水波泵的俯视图；
图3是以较大比例显示的所述泵的密封件的垂直截面图；
图4显示了位于第一位置的浮筒；
图5显示了图4所述浮筒位于第二位置；和
图6显示了一个水波泵的可选择实施方式。
具体实施方式
在附图中，附图标记1表示水波泵，其包括潜水泵部分2和浮筒4。
所述潜水泵部分2包括采用相对较长外形的泵外壳6，在大体垂直的操作位置上，连接至导管8的管位于泵外壳6内部并固定至泵外壳6。
导管8的上部连接至泵外壳6，否则其将通过泵外壳6自由地向下伸出。水波泵1的出口10连接至导管8的上部并与之相通。
泵外壳6连接至环绕泵外壳6的浮锚12。浮锚12具有金字塔的平截头体的形状，与其水平尺寸相比具有较小的高度，所述金字塔的“顶部”在潜水泵部分2位于工作位置时面朝下。
已经证明，当浮筒4试图将潜水泵部分2从水中向上移动时，浮锚12的这种设计使其在水中获得最大可能性的位移阻力(displacement resistance)方面很有优势。
浮锚12设有多个翼片14。翼片14在下部围绕大体水平的轴线16铰接。
当浮锚12在水中向上移动时，翼片14关闭，而当浮锚12通过水向下移动时围绕轴线16旋转至打开位置。与无翼片的设计相比，翼片14使得潜水泵部分2的下降速度(draw-down velocity)极大地增加。
泵管18以轴向可滑动的方式环绕导管8的自由部。泵管18的上部连接至紧固件20，紧固件20包括密封件22，请参阅图3，密封件22密封导管8。
在下部，泵管18通过第一止回阀26与入口24相通。
重物28通过铅垂线30连接至入口24并设置为当浮筒4降低时使泵管18穿过水向下移动。
出口10通过第二止回阀32与下游管路系统(未示出)相通。
泵绳索34通过泵外壳6中的引导件36从紧固件20向上延伸至绳索联结器38。绳索联结器38通过浮筒绳索40连接至浮筒4。
在初始位置，泵管18处于较低位置，绳索联结器38邻接引导件36。导管8和泵管18中充满水。
当浮筒4由波浪升起时，泵管18通过紧固件20、泵绳索34、绳索联结器3 8和浮筒绳索40向上移动。第一止回阀26关闭时，密封件22使导管8与泵管18之间不存在水。
这使得导管8与泵管18中产生水压，从而使泵外壳6向上移动。此移动主要是通过浮锚12阻止的。
因此，在压力较高处的水通过打开的第二止回阀32从出口10流出。
当浮筒4降低时，由于第二止回阀32对于通过入口24的流入的水关闭而第一止回阀26对于通过入口24的流入的水打开，重物28将把泵管18向下拉。
在这个阶段，如上所述，由于翼片14打开并且有助于浮锚12以更高的速度下沉，全部泵部分2沉入水中。重物28和泵管18以比浮锚12和泵外壳6大得多的速度下沉，因此保证了在泵管18沿着导管8向下移动的过程中水能够流入泵部分2。
在一个优选实施方式中，浮筒4的形状为细长体，参见附图4和5。浮筒4可以为船形或者具有其他适当的轮廓，例如三角形截面，其中三角形的一个角面朝下。
浮筒绳索40连接至浮筒4一个端部的浮筒绳索附着点42上，而浮筒4的相对的端部设有平衡配重44。
浮筒4的设计使得当浮筒绳索附着点42处于波谷中时浮筒绳索附着点42移动到波谷的水面46之下，参见图4，而当浮筒绳索附着点42位于顶部位置时，浮筒绳索附着点42由于平衡配重而将被提升到波峰48之上的水平面，参见图5。
在一个可选实施方式中，请参见图6，水波泵1设有传统浮筒50和两个浮锚12。
