Description

改装风力涡轮机的装置和方法
技术领域
本发明涉及改装风力涡轮机的装置和方法。
背景技术
有时，需要改装现有的且已安装的风力涡轮机，以使其容量适应环境条件。
例如，可以从风力涡轮机的轮毂上拆除风力涡轮机的叶片，并且可以将其下降至地面。可以将比该组旧叶片长的一组新叶片安装在轮毂上，以增加风力涡轮机容量。
可以修理乃至检查已拆除的叶片以进一步使用。
这种改装工作耗时并且很昂贵。
另外，在海面上的风力涡轮机被处理的情况下，该工作需要在无风天气条件下进行。
此外，需要专门设计的带有大型起重机的船来去掉旧叶片并安装新叶片。
发明内容
因此，本发明的目的是要提供一种改进的装置和方法，其允许以容易、省时和合算的方式改装风力涡轮机。
通过权利要求1的特征并且通过权利要求8的特征来达到该目的。
本发明的优选实施例是从属权利要求的目的。
根据本发明，通过风力涡轮机的叶片中的至少一个叶片对风力涡轮机进行改装。该叶片被制备成用于与风力涡轮机的轮毂相连接。
扩展单元被设计和制备成用来增大叶片的表面积。该扩展单元和该叶片被设计和布置成通过开口相互作用，相应地，该开口可以布置在该叶片旁边和/或该扩展单元旁边。该扩展单元通过粘合剂与该叶片相连接，所述粘合剂至少部分地施加在该开口内。
所要求保护的发明允许很容易地改装现有的且已安装的风力涡轮机。
本发明允许在风力涡轮机所在地乃至工厂旁边改装叶片而无需复杂的特征。
本发明可以很便宜地应用，因为可以对风力涡轮机进行改装而无需拆除叶片。
优选地，该扩展单元以形状配合的方式与该叶片相连接，而该粘合剂用于使它们相互紧固或固定。
优选地，该扩展单元被设计并且布置成作为翼尖延长该叶片。
优选地，该开口为空腔，其被布置在该扩展单元或翼尖旁边。
优选地，该扩展单元包含该开口。因此，可以通过该扩展单元改装已安装的叶片。
优选地，该开口是该叶片末梢的凹空穴/印记(negative void/print)。因此，该空穴以形状配合的方式与该叶片的末梢相作用。
优选地，该叶片与该扩展单元之间的接触区域完全用该粘合剂覆盖。因此，实现了非常牢固的连接。
优选地，该粘合剂表现出低的粘性。
优选地，该粘合剂是聚酯树脂或者乙烯酯树脂或者环氧树脂粘合剂或者聚亚安酯粘合剂或者硅树脂粘合剂。
优选地，该粘合剂通过压差或者通过技术真空施加到该开口中，其沿该叶片与该扩展单元之间的接触区域相互作用。
优选地，根据这些步骤，将该扩展单元附接到已与该风力涡轮机相连接的叶片：
使该叶片绕该轮毂旋转，直到该叶片的末梢端指向地面。以将该扩展单元的开口指向该叶片的末梢端的方式，将该扩展单元与该叶片的末梢端对齐。
将粘合剂填充到该开口中。提升该扩展单元，直到它与叶片的末梢端紧密接触。
以所得到的提升动作沿该叶片的末梢端与该扩展单元之间的接触区域挤压粘合剂的方式，将该叶片与该扩展单元一起绕该轮毂旋转。
附图说明
借助于附图更详细地示出本发明。这些图示出了优选配置，而且并非限制本发明的范围。
图1示出了根据本发明改装风力涡轮机叶片的第一步骤。
图2示出了根据本发明改装风力涡轮机叶片的第二步骤。
具体实施方式
图1示出根据本发明改装风力涡轮机叶片的第一步骤。
风力涡轮机的叶片BL示出末梢端TE，而末梢端TE被制备成用于与扩展单元EU相连。
扩展单元EU被设计为翼尖，且被制备成增大叶片BL的表面积。
在该扩展单元EU旁边，布置了开口OP。开口OP可以成形为空腔，其被制备成接纳叶片BL的末梢部分——末梢端TE。
开口OP填充有液体粘合剂LA。
扩展单元EU通过至少部分地施加在开口OP内的粘合剂LA与叶片BL相连接。
开口OP被成形和设计为叶片BL的末梢端TE的凹的空穴/或压印。因此，扩展单元EU最终以形状配合的方式与叶片BL相连接。
图2示出了根据本发明改装风力涡轮机叶片的第二步骤。
叶片BL与扩展单元EU紧密接触。因此，液体粘合剂LA沿叶片BL与扩展单元EU之间的接触区域CA分布。
开口OP内液体粘合剂LA的量，其中该开口可能被成形为上文所述的空腔。按如下方式选择开口OP，即使得液体粘合剂如上文所述地进行分布。优选地，以在改装工作期间几乎没有液体从开口溢出的方式来选择液体粘合剂的量。
