Description

由具有低转速叶片的轮圈元件组成的水轮
技术领域
本发明涉及一种由具有低转速叶片的轮圈元件和集成的发电机组成的水轮，其中，该水轮为发电可以通过对应配置的水叶片被流动地、射击地或者自由下落地流出的水驱动，其中，一环形元件与该水轮同心连接并且具有置入的永久磁铁以形成发电机的转子，并且，与永久磁铁对应配置地安置有一些电线圈作为定子。
背景技术
由功能所决定，水轮具有带有大的转矩的相对低的转速。因此通常为发电而将一个多级的机械传动装置与水轮的轴颈连接，并且将该传动装置的输出轴通过一个传输装置与发电机连接。
在水量变化时，特别在水量增多时，功率和转矩升高，使得水轮轴和传动装置必须接收相对高的峰值转矩。
因此在实践中与正常负载相比采用具有因子3的部件的设计。由此产生相对重的和成本高的构件。
这些已知的组件具有减小的效率，特别是由于机械转换损失。此外，运动的部件受到磨损并且需要费用高的维护。
根据DE 102 18 433 A1已知一种由具有低转速叶片的轮圈元件组成的水轮，以便组装相对大的水轮并且仅就地进行总装配。
根据EP 1 876 350 A1已知一种发电机组件的布置，该发电机组件包含涡轮组件，其中，通过该涡轮形成具有磁铁的旋转转子和包围在外部的定子，以形成发电机。在此，与水轮相比涉及快速运行的组件，这些组件不能转用到水轮上。附加地在此也可看到一种叶轮组件，其中，定子通过在圆周上包围的线圈形成。在此存在这样的缺陷，产生的力与组件的支承装置间隔开地出现并且在转用到水轮上时需要加强的基座装置。
发明内容
本发明的任务在于，提供一种无传动装置的所述类型组件，该组件通过简单的结构允许容易地运输和以模块方式装配转子，保证定子元件适配于当前的情况，并且此外将生成能量时产生的力直接导入到承载结构中。
根据本发明由此实现该任务：转子的环形元件由一些以模块方式对应配置的、具有置入的永久磁铁的单个段组成，并且对应配置至少一个带有电线圈的相应部分环作为定子，该部分环在水轮的被水加载的一侧上借助其保持元件安置在承载结构的区域中。
由此能够实现大的发电机直径并且由此确保转子部件简化的运输和装配，同时能够按照当前的势能通过单个的定子段来对应配置定子。在生成能量时产生的制动力在此通过定子元件的组件直接导入到基座中。
本发明的一个有利构型在于，在环形元件上设置的永久磁铁作为转子与作为定子的、具有线圈的部分环对应配置地设置在环形元件的前侧、后侧、内表面或者外表面的区域中。
为提高效率而规定，将用于接收永久磁铁的这些区域相组合。
一种实施方式在于，永久磁铁梳状地加工到转子的环形元件的结构中。
此外提出，水轮由一些轮圈段形成，用于形成转子环形元件的那些单个段集成在这些轮圈段中。
附图说明
在附图中示意表示本发明的实施例。附图示出：
图1整体结构的立体图；
图2转子和定子的立体局部示图，其中，转子作为环形元件接收梳状地加入的永久磁铁，并且在两侧上具有线圈的定子段偏移半个线圈地对应配置；
图3在流水中的浮体上的替换布置；
图4用水轮作为背压机(Staudruckmaschine)的另一设置。
具体实施方式
在实施例中设有水轮4，其中，按照图1，上冲击式水轮4构造有一个对应配置的供水槽7，并且通过一个位置固定的基座6以已知的方式安置。在此，水轮4由一些单个的轮圈元件构成。
一个环形发电机与水轮4耦合，该环形发电机由作为环形元件的转子2构成并且与水轮4固定连接。在此与水轮体的轮辐连接或者直接安放在所形成的环上。
该环形元件作为转子2以模块方式由装备有相应的永久磁铁8的单个段3组成。在此使用大功率磁铁，例如以商品名NEODYN磁铁已知的大功率磁铁。这些永久磁铁8在实施例中安置在作为转子2的环形元件的前侧、后侧、内表面或者外表面上，与作为定子的、带有线圈9的部分环1对应配置。
按照图2，永久磁铁8梳状地加入到转子2的单个段3中。单个段3例如可以无铁地用塑料制造。
给具有单个段3的转子2对应配置作为定子的部分环1，这些部分环承载有相应的电线圈9并且与转子一起形成发电机。在此这些部分环通过一个保持元件5安置在承载结构6上。部分环1的数量从水轮安放位置的当前水力机械势得出。
按照图2，定子的部分环1对应配置在转子的环形元件的两侧，其中，线圈9彼此各错开一半宽度地设置。
按照图3，一个锚定的浮体10承载水轮4，其中，对应的叶片9被流水的流动驱动。
有利的是，这些部分环1的数量与水轮安放位置的水力机械势相匹配，其中，这些部分环覆盖转子2的下面三分之一，并且对浮动特性及其重心和防倾斜安全性起到有益作用。
在根据图4用水轮4构成背压机时(水轮的叶片9设置在一个圆柱形的空心体上)，叶片9既通过重力也通过水的流动来驱动。
有利的是，将发电机的转子2集成地置入到圆柱形的空心体的承载结构中并且使环形元件1的数量与水轮安放位置的水力机械势相匹配。
当然，可以将相应的环形发电机安置在水轮4的两侧。
