本发明涉及一种遮挡叶片支撑件型垂直轴风力机,属于风力机设计、构造技术领域,以及可再生能源、节能减排和环境保护技术的开发与设计领域。
背景技术
据申请人了解,目前市场上运行的风力发电机组中,所用风力机绝大多数为风轮转轴水平放置的水平轴涡轮式风力机,属于高风速风力机范畴,其中低风速性能差,在年均风速

发明内容
基于此,有必要针对目前的垂直轴风力机所存在的问题,提供一种遮挡叶片支撑件型垂直轴风力机,通过对风轮结构的改进,提高风力机性能。
上述目的通过下述技术方案实现:
一种遮挡叶片支撑件型垂直轴风力机,包括绕垂向旋转轴线转动的风轮以及确定垂向旋转轴线的承重体,所述风轮包括轮架、以及分布于轮架周边的叶片,所述轮架与承重体转动连接;其中所述轮架的上部和下部分别具有一组叶片支撑件,各叶片支撑件远离垂向旋转轴线的末段或末端分别连接有挡板;所述挡板位于相应叶片支撑件末段与相应叶片之间,或所述挡板的边缘与相应叶片支撑件的末端一体成型;所述轮架上部的挡板与轮架下部的挡板上下对应,对应的挡板之间连有相应叶片;所述叶片的两端与相应挡板直接连接、或经连接件连接。
申请人在实践研究中发现,将叶片两端安置在挡板上,且挡板遮挡叶片支撑件末段、或挡板直接与叶片支撑件末端一体化起到相同的遮挡作用,这样,一方面能遮挡叶片支撑件,消除其对流场产生的不利于叶片吸收风能的扰动,提高风能利用效率;另一方面,该结构中的挡板可作为中大型风力机功率控制器的安装平台,提高风力机的性价比;此外,能使叶片在整个高度上都吸收风能,起到聚风作用,减少叶片端部的性能损失,提高叶片的驱动力和风能利用效率。
采用含板件连接件的优选结构后,能更好地优化配置功率控制部件,利于提高风力机性能。当采用弹性控制器时,则以叶片离心力与弹性力之间的作用力平衡方式实施风力机功率控制,且由于利用了力的分解原理,能降低对弹性伸缩控制器伸缩件的精度或灵敏度要求而降低控制成本;当采用电动控制器时,则以电控方式实施风力机功率控制。
当存在多个风轮时,互为反转的成对风轮配置,不仅能自动调整成对风轮形成的迎风面垂直于风向、在迎风面避开立柱或塔架对风轮的遮挡,从而确保风轮充分吸收风能,而且利于风轮起转,消除绕立柱或塔架的转动矩和离心力载荷,提高集成为大功率系统的整体稳定性。
本发明的有益效果是:本发明通过对风轮结构的改进,尤其是对叶片安装结构的改进,能消除叶片支撑件对流场产生的不利于叶片吸收风能的扰动,提高风能利用效率;能使叶片在整个高度上都吸收风能,起到聚风作用,减少叶片端部的性能损失,提高叶片的驱动力和风能利用效率。

图26、图27、图30至图33、图36所示的实施例都是在能绕立柱转动的横杆或桁架上、且在立柱两侧安装互为反转的双风轮或双组多风轮的风力机,它的功能是自动使与横杆或桁架平行的垂面与风向垂直,其原理是横杆或桁架两边互为反转的风轮旋转会产生绕立柱的互为反向的转动力矩,当风向与所述垂面不垂直时,风向上游风轮产生绕立柱的转矩大于风向下游风轮的所述转矩,这就会驱动横杆或桁架绕立柱转动,直到两边风轮的所述转矩相等的位置停止,这个位置就是风向与所述垂面垂直的位置。它的有益效果是风轮能自动在迎风面避开立柱,两个风轮都能保持最大的风能利用效率。图29、图34和图37所示的实施例和图15、图16、图18至图21所示的轮架都有双型或四型悬臂、短轮轴和设置抗拉件的轮架,这类轮架的有益效果是增强了轮架的刚度和负重能力、降低了风轮重心和减小了离心荷载对斜撑或悬臂的强度要求,突破了制约垂直轴风力机高性能大型化发展的技术瓶颈。图37所示的实施例是水上浮动集成式风力机,用多个风力机提高了系统的功率容量,而不增加系统的高度,它的有益效果是既提高了系统功率、又确保了浮动式平台的低重心要求,降低了大功率利用水面上优质风能的成本。
本发明的轮架不限于以上所述,在图6至图21所示的轮架中,将一些部件彼此互换又能构成新的轮架,如将图18与图19、图20与图21所示轮架1之间轮轴A顶端以上的部件互换又构成四种新的轮架;将一些结构移植也能构成新的轮架或新的部件,如将图15所示轮架1中的悬臂B和悬臂D及其挡板绕旋转轴心线三重旋转对称、并在三个悬臂B之间连接一个三角形抗拉件4和在三个悬臂D之间连接两个三角形抗拉件4又构成一种可安装三个叶片的新轮架,又如将图15所示轮架1中的轮轴A和悬臂B去掉、再将悬臂D以传动体R的圆平面所在平面为基面向上映射、能构成如图16所示类型的二重旋转对称的新轮架,再如将图1c和d中虚线所示的弧形悬臂B替换上述一些轮架1中对应的折型悬臂B又能构成一些新轮架。本发明的垂直轴风力机不限于所述的实施例,如上述的新轮架安装叶片组成的风轮与上述的承重体组合可构成的新实施例,又如图25至37所示的实施例中所述对称性兼容的风轮与承重体3互换可构成的新实施例,如此不胜枚举。本发明的实施例是以双叶片和三叶片风轮为例,但本发明的所述叶片支撑件绕垂向旋转轴线四重旋转对称、五重旋转对称等等分布,也能构成本发明所述结构的四叶片、五叶片等等风轮的风力机。除上述实施例外,本发明还可 以有其他实施方式。凡采用等同替换或等效变换形成的技术方案,均落在本发明要求的保护范围。
以上所述实施例仅表达了本发明的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对本发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干变形和改进,这些都属于本发明的保护范围。因此,本发明专利的保护范围应以所附权利要求为准。
