Description

风力发电的结构 技术领域
本发明涉及风力发电的结构技术， 特别涉及一种运用单叶扇， 同时能降低 因叶扇彼此间运转所产生的气流， 进而提升整体电力转换效能的风力发电的结 构。 背景技术
由于石油能源存量日渐减少， 所以替代能源的开发巳是迫在眉睫； 然而替 代能源除了要能替代石油能源外， 更要能具有环保性， 以免污染环境； 太阳能 与风能是目前最能符合以上条件的替代能源。 目前风能或太阳能的使用大都是 将其转换成电能。
风力发电一般是采用水平轴式的风力发电机， 并且将发电机组及扇叶配置 在塔顶； 其体积庞大且费用高昂。 中国台湾专利公开 200846551号及公告 M327926号专利， 皆揭露一种直立式且能自动追踪风向的风车， 将其搭配适当 的发电机， 便可成为风力发电设备。 上述两件专利案的风车构造是在一转轴上 组设多个框架， 且在框架内组设多个可转动的叶片， 并使各叶片分别位于转轴 的相对两側； 在风力作用于各叶片时， 企图以风力来使框架转动进而驱动转轴 使发电机产生电力。
值得注意的是， 上述两件专利的每一叶片都可独立摆动， 所以当风力作用 于叶片时， 每一叶片可能皆以独立摆动的形式对应风力； 此时位在转轴一侧的 各叶片若产生颀时针的扭力， 位在转轴另一側的各叶片便会产生逆时针的扭力， 如此扭力互相抵消反使框架无法转动， 而转轴也无法转动并使发电机运作。
由此得知， 目前市面上的风力发电， 在运用多叶扇的方式时， 会受到气流 的干扰而降低风力转换电力的效率。
是以， 要如何解决上述现有技术的问题与缺失， 即为本发明的发明人与从 事此行业的相关厂商所亟欲研究改善的方向所在。 发明内容
本发明的主要目的在于： 通过此重量块能让叶扇达到平衡的状态， 同时在 运用多片叶扇于基体时， 则不会受到彼此间在运转时所产生的气流影响， 进而 获得最佳的发电效率。
为达上述目的， 本发明为一种风力发电的结构， 其包括：
一基体， 该基体设置至少一个安装部；
至少一叶轮， 该叶轮具有一枢设于该安装部的转轴， 且该转轴结合单一叶 扇； 及
一重量块， 该重量块装设于该转轴上并对应于该叶扇位置处。
所述的风力发电的结构， 其中， 多个该叶轮一次柩设于该基体同一面。 所述的风力发电的结构， 其中， 多个该叶轮一次柩设、 并以交错方式柩设 于相对应面。
所述的风力发电的结构， 其中， 该重量块的重量等同于该叶扇重量。
所述的风力发电的结构， 其中， 该叶扇装设一供调整该叶扇角度的调整轴。 本发明的有益效果在于： 通过此重量块能让叶扇达到平衡的状态， 同时在 运用多片叶扇于基体时， 则不会受到彼此间在运转时所产生的气流影响， 进而 获得最佳的发电效率。 附图说明

为达成上述目的及功效， 本发明所采用的技术手段及构造， 兹绘图就本发 明较佳实施例详加说明其特征与功能如下， 以利完全了解。
请参阅图 1所示， 为本发明较佳实施例的立体图， 由图中可清楚看出本发 明为一种风力发电的结构， 风力发电的结构 1包括： 一基体 10， 该基体 10设置 至少一个安装部 102; 至少一叶轮 12, 该叶轮 12具有一枢设于该安装部 102的 转轴 120， 且该转轴 120结合单一叶扇 122; 及一重量块 14, 该重量块 14装设 于该转轴 120、 并对应于该叶扇 122位置处， 而重量块 14的重量等同于该叶扇 122重量。
凭借上述的结构、 组成设计， 兹就本发明的使用作动情形说明如下， 请同 时配合参阅图 2所示， 为本发明较佳实施例的运作状态图， 由图中可清楚看出， 以叶轮 12—次枢设多个于该基体 10同一面为例， 当叶轮 12朝向迎风面时， 各 叶轮 12的单一叶扇 122则会受风力而推动进而旋转， 由于仅单一叶扇 122, 因 此叶轮 12所产生的气流则相对减少， 也因此， 邻近的其余叶轮 12受到周遭气 流的影响相对降低， 进而能够提升整体电力转换效能， 另外， 重量块 14的重量 等同于该叶扇 122重量， 因此能让叶扇 122达到平衡的状态。
请参阅图 3及图 4所示， 为本发明另一较佳实施例的立体图及另一较佳实 施例的运作状态图， 以叶轮 12—次枢设多个、 并以交错方式枢设于相对应面为 例， 此方式不会受到环境迎风面的影响， 由于运用此双面的叶轮 12, 能扩大迎 风面的范围， 进而提升整体的发电效率， 当两对应面其中一面的叶轮 12朝向迎 风面时， 各叶轮 12的单一叶扇 122則会受风力而推动进而旋转， 由于仅单一叶 扇 122, 因此叶轮 12所产生的气流则相对减少， 也因此， 邻近的其余叶轮 12受 到周遭气流的影响相对降低， 进而能够提升整体电力转换效能， 另外， 重量块 14的重量等同于该叶扇 122重量， 因此能让叶扇 122达到平衡的状态。
请参阅图 5所示， 为本发明又一较佳实施例的运作状态图， 此以双面、 且 大面积的叶扇 122为主， 而在叶扇上 122装设一供调整该叶扇 122角度的调整 轴 1220, 利用调整轴 1220能让叶扇 122改变受风的面积， 以达到改变风力发电 的结构的效率。
然而， 以上所述仅为本发明的较佳实施例而已， 非因此即局限本发明的专 利范围， 故举凡运用本发明说明书及图式内容所为的简易修饰及等效结构变化， 均应同理包含于本发明的专利范围内， 合予陈明。
综上所述， 本发明的风力发电的结构于使用时， 为确实能达到其功效及目 的， 故本发明诚为一实用性优异的发明， 为符合新型专利的申请要件， 爰依法 提出申请， 盼 审委早日赐准本发明， 以保障发明人的辛苦发明， 倘若钧局审 委有任何稽疑， 请不吝来函指示， 发明人定当竭力配合， 实感德便。
