Description
技术领域
本发明涉及发电装置,更具体地涉及叶轮发电装置。叶轮发电装置能够将流水(例如海水)或风的能量转换成有用的能量形式。叶轮发电装置包括流体汇合引导装置,叶轮和多个发电设备。流体汇合引导装置可以增加流体速度并将进入两个相邻导流板之间的空间的流体分成多个旋转流体部分。流体以最佳角度撞击叶片。发电设备由叶轮驱动。总发电量由多个发电设备承担。单个发电设备具有相对小的重量。它可以高速旋转。它降低了安装风险。
背景技术
传统的潮汐流发电机的功能与风力叶轮机非常相似,因此通常被称为潮汐叶轮机。然而,传统的潮汐流发电机具有以下缺点:如果它漂浮在海面上则不稳定。如果将其固定在海底,施工是困难且危险的。仅提供一个发电机。海流直接撞击叶片以进行旋转,这是不利的,因为叶片直径小,叶片的流体撞击区域小,并且发电量低。在海底安装配电线路很困难。发电成本非常高。潮汐流发电机的安装存在风险。
根据台湾地区海洋技术研究中心撰写且于2007年12月由台湾地区经济部能源部出版的“2007年能源技术研究报告”,流体速度为1.2m/s,海岸线距离大于20千米、海水深度大于100米的场地适合安装潮汐流发电机。因此,只有台湾地区的东海岸的海域才适合选址。特别重要的是,如果海上场地的流体速度小于1.2m/s,则不经济。
因此,希望开发一种发电机,当其安装在海流大于0.3m/s、从场地到海岸线的距离大于1km以及深度大于60m的海上时,能够经济地发电。
发明内容
因此,本发明的一个目的是提供一种叶轮发电装置,包括一流体汇合引导装置,该流体汇合引导装置包括一壳体和设于该壳体中的多个导流板,其中该壳体包括位于第一端的一入口,位于第二端的一弯曲构件,以及横向通道作为出口;一叶轮,包括两个间隔开的轮缘,以及多个叶片,且该叶片呈环状地等间距分隔设在该出口中;其中该多个叶片与该出口同心地设置,且每个轮缘包括多个齿。
本发明与先前技术比较,具有以下优点:
由于提供了流体汇合引导装置,流体不会撞击叶片。相反的,在使叶片旋转之前,让流体先由流体汇合引导装置引导。该流体汇合引导装置不仅增加了流速,还将流水的能量转换成有用的能量形式。
没有轮轴的叶轮可以在狭窄的空间内自由旋转。该叶轮可具有多种不同设计中的一种,其叶片的流体冲击区域大为增加,叶轮的直径大为增加,叶片的数量可大为增加。即使在流体速度低时,叶轮也会产生很大的电能。发电性能大为改进。
多个发电设备由叶轮驱动,总发电量由多个发电设备一起承担。每个单一发电设备都仅有较小的重量。这可以降低安装或拆卸发电设备的风险。此外,叶轮发电装置可以安装在海平面上,以防止发电设备浸没在海水中。
因此,本发明的第一方面为一种叶轮发电装置,其包括一流体汇合引导装置,该流体汇合引导装置包括一壳体和设于该壳体中的多个导流板,其中该壳体包括位于第一端的一入口,位于第二端的一弯曲构件,以及两侧的弯曲构件的横向通道设有一流体出口;一叶轮,在该弯曲构件的两侧上包括两个间隔开的轮缘,在各该轮缘之间呈环状地设有多个叶片,且该叶片等间距分隔设在该流体出口中;其中该多个叶片互相以角度关系设置为放射状圆形阵列,并与该流体出口同心地设置,且每个轮缘包括多个齿轮。
根据本发明的实施例,各该导流板以相互等间距分隔呈环状设在该壳体中,每个导流板的两端分别对应固定在该壳体表面,且所有导流板均与该流体汇合引导装置的流体出口为同心排列,使进入两个相邻导流板之间的流体会被分成多个单独旋转的流体部分。
根据本发明的实施例,流体汇合引导装置的入口的横截面积大于其出口的横截面积。
根据本发明的实施例,叶轮没有轮轴。
根据本发明的实施例,叶轮发电装置还包括多个定位装置,该定位装置分别对应固定在该壳体的弯曲构件的两个相对表面,其中该叶轮的轮缘被配置为相对于该定位装置进行旋转地移动,每个定位装置包括一定位轮和一通过该定位轮中心的轮轴,且该定位轮的轮轴固定在该壳体的弯曲构件的任一表面。

具体实施方式
叶轮发电装置参照图1至图10,本发明的叶轮发电装置包括有一流体汇合引导装置10,叶轮20,多个定位装置23,多个发电设备30和多个支撑件40。为了方便描述的目的,支撑件40以减小的高度示出。
在图2中省略了叶轮20和定位装置23,流体汇合引导装置10包括一壳体11和设置成圆环形的多个导流板12。壳体11包括有外壳111和罩体112。罩体112具有入口101。外壳111包括弯曲构件103和横向通道113,且导流板12设置在横向通道113周围。每个导流板12的两端分别固定到外壳111的两个内表面处。另有一出口构件122设置在任何两个相邻的导流板12之间。出口构件122共同作为流体汇合引导装置10的出口102。
如图5A和图6A所示,进入两个相邻导流板12之间的入口构件121的流体会被分割为多个旋转流体部分,每个流体部分会由相邻导流板12之间的出口构件122离开,以分别带动叶轮20的多个叶片22中的一个进行旋转。流体汇合引导装置10的入口101的横截面积大于出口102的横截面积。因此,可使流体在出口102处增加其流速。
以下详述本发明其中一特征。流体所分出的多个旋转流体部分会各自撞击叶片22,使叶轮20以最佳角度旋转,以利将流动水的能量转换成有用的能量形式。
参照图3,接着描述流动路径和操作原理。第一流体部分131,第二流体部分132和第三流体部分133从入口101流入流体汇合引导装置10,先会聚为第四流体部分134。第四流体部分134又再借由壳体11的弯曲构件103进一步会聚为第五流体部分135。其他部分的流体则流进在各导流板12之间的入口构件121。
如图5、图6和图6A所示,在流体被开始分割时,在两相邻的导流板12之间会形成第六流体部分136。由于将流体被分割后形成多个旋转流体部分,使第六流体部分136再合并为第七流体部分137,第七流体部分137作用在叶片22上,使叶轮20以最佳角度旋转,从而将流水的能量转换为更有用的能量形式(例如,旋转机械能)。此外,当第七流体部分137沿叶片22的弯曲表面流动时,第七流体部分137的能量被传递到叶片22。此外,当流体离开叶片出口221时,形成第八流体部分138。最后,流体经由横向通道113离开流体汇合引导装置10。
如图4所示,叶轮20不具有轮轴并且包括两个间隔开的轮缘21、设在轮缘21之间的多个叶片22以及多个定位装置23。叶片22依等间距相隔排列成实质上圆环状,横向通道113设置在其中。轮缘21包括多个齿211。定位装置23分别固定到壳体11的两个相对表面。轮缘21具有一定程度的定位并相对于定位装置23浮动和旋转地移动。定位装置23包括轮231和轮轴232。
如图7、图7A和图7B所示,轮轴232穿过轮231的中心设置。轮轴232固定到壳体11的弯曲构件103的任一表面。如上所述,轮缘21可相对于定位装置23或在其内旋转地移动。如图7、图7A、图7B和图8所示,响应于流体致动叶片22,没有轮轴的叶轮20可在狭窄空间中(即在定位装置23内)自由地旋转。
参照图11和图12,显示本发明的第二实施例定位装置23A。定位装置23A改为围绕轮缘21旋转。定位装置23A包括第一档板23A1和第二档板23A2。第一档板23A1固定到壳体11的弯曲部分的任一表面。定位装置23A依等间距相隔排列成实际上的环状。第二档板23A2的一端成形为与第一档板23A1连接,而与壳体11的表面成形为有间距的连接。如上所述,轮缘21适配为在第二档板23A2的狭窄空间内旋转。
因此,没有轮轴的叶轮20可以通常在有限空间中自由地旋转。叶轮20也可以具有多种不同设计中的一种,其中叶片22的流体撞击区域大为增加,叶轮20的直径大为增加,且叶片22的数量大为增加,因此,即使在流体速度低时,叶轮20也会产生很大的电能。结果,发电性能大为改进,这是本发明的主要目的。
多个发电机30中的每一个包括齿轮31和设置在壳体11外部的发电机本体32。齿轮31位于发电机32的轴上,且齿轮31与轮缘21的齿轮211啮合(参见图1和图9A)。发电设备30可以配合叶轮20的旋转而发电。因此,流体的势能能转换成电能。发电机30由叶轮20驱动。总发电量由多个发电机30共同承担。因此,单个发电机30具有相对小的重量。这具有降低安装或拆卸发电机30的风险的好处。此外,本发明的电动叶轮发电机可以安装在海平面60的上方。这还具有防止发电设备30浸泡在海水中的优点。因此让叶轮发电装置的使用寿命大为延长。发电设备30的齿轮31可以由变速齿轮箱代替。此外,变速齿轮箱与轮缘21的齿轮211啮合。
将进一步理解的是,叶轮发电装置能够将流水(例如,海水)的能量以及风转换成有用的动力形式。
通过紧固在海底50的多个支撑件40来固定本发明的叶轮发电装置。此外,壳体11的底部由支撑件40支撑。结果,叶轮发电装置是安全的。
尽管以术语描述了本发明的优选实施例,但本领域技术人员应该理解,本发明可以在所附权利要求的精神和范围之内的变型来实现。
