Description

垂直轴风力发电机的风叶系统
技术领域
  本发明涉及一种垂直轴风力发电机的部件,主要是指一种垂直轴风力发电机的风叶系统。
背景技术
  最早的垂直轴风力发电机的风叶采用的是圆弧形双风叶的结构,也就是所谓的Φ型或称为达里厄双风叶结构,这种结构的风叶由于其受风面积小,相应的需要较高的启动风速,带这种风叶的垂直轴风力发电机一直未得到大力发展,究其原因是其发电效果始终不太理想。
  近年来,人们提出了采用H型风叶来代替传统圆弧形双风叶的结构,  H型垂直轴风力发电机的风叶是采用空气洞力学原理,针对垂直轴旋转的风洞模拟,风叶采用飞机翼形形状,在风轮旋转时,它不会受到因变形而改变效率等;它用垂直直线4-5个风叶组成,由4角形或5角形形状的轮毂固定、连接风叶的连杆组成的风轮,由风轮带动稀土永磁发电机发电送往控制器进行控制,输配负载所用的电能。
  根据H型风力发电机的原理,风轮的转速上升速度提高较快(力矩上升速度快),它的发电功率上升速度也相应变快,发电曲线变得饱满。在同样功率下,垂直轴风力发电机的额定风速较现有水平轴风力发电机要小,并且它在低风速运转时发电量也较大。这种H型风力发电机的风叶系统虽然有上述优点,但是,在风轮的转速上升速度及发电曲线方面也还存在许多需要改进之处。
发明内容
  本发明目的是向社会提供一种在微风下即可以启动风力发电机,并且风阻非常小的垂直轴风力发电机的风叶系统。
  本发明的技术方案是:设计一种垂直轴风力发电机的叶片系统,包括一个其横截面为多边形的封闭体,在所述封闭体的至少两个侧面上各设有一个风口,其中至少一个风口为进风口,另一个风口为出风口,每个风口在所在侧面上的位置与其它风口各自所在侧面上的位置基本相同,构成一个斜向风流通道,在所述封闭体内设有一根风轮轴和至少一对风叶,受力的风叶处在斜向风流通道之中,风从一个风口进入,从对面的另一风口吹出,在封闭体内吹动所述风叶旋转,风叶则带动所述风轮轴旋转。
  所述风轮轴的轴心与所述多边形的内切园的圆心重合。
  作为对本发明的改进,所述多边形的封闭体的横截面为正方形,在所述封闭体的每个侧面上各设有一个风口,相邻两侧面上的风口处在基本相同的位置。
  作为对本发明的改进,所述多边形的封闭体的横截面为三角形,在所述封闭体的每个侧面上各设有一个风口,相邻两侧面上的风口处在基本相同的位置。
  在至少一个风口外侧设有一个喇叭状的导风罩。导风罩的外口高是内口高三倍、外口宽是内口宽四倍为最佳。
  当所述喇叭状的导风罩为一个时,在所述封闭体上相对于所述导风罩所述的对面还设有一个用于调整导风罩方向的风舵。
  在所述导风罩内设有一个垂直的挡风片,所述挡风片将导风罩的内空分隔成左右两个部分。
  所述导风罩的侧面是平面的或者是弧面的。
  所述封闭体的上、下面分别还设有上底板和下底板,所述上底板和下底板与所述封闭体的紧固连接。
  所述风叶包括框架及挡风面,所述挡风面设置在所述框架内,所述框架与所述风轮轴固定连接。
  所述风叶包括框架及挡风面,所述挡风面设置在所述框架内,所述框架与风叶轴承活动连接,在所述风轮轴的上端或下端设有十字形支杆,所述风叶设在十字形支杆下方,所述风叶轴承设置在所述风轮轴上,或者设置在十字形支杆上,在十字形支杆的外端设有一根弹性件,所述弹性件的另一端与相邻的所述风轮的外框相连接。
  所述弹性件为弹簧或橡皮筋。
  本发明中的所述多边形为3-12个边的多边形。
  所述风叶包括边框和挡风面,所述挡风面设置在边框内,所述挡风面与所述边框之间用弹性件连接。
  所述风叶包括边框和挡风面,所述挡风面设置在边框内,所述挡风面被分成至少两个部分,每个部分之间通过弹性件相连接。
  所述风叶包括边框和挡风面,所述挡风面设置在边框内,所述挡风面被分成至少两个部分,每个部分与弹性件相连,所述弹性件再与边框连接。
  本发明中的风叶也可以设计成凹面的结构。
  采用了本发明垂直轴风力发电机的风叶系统的垂直轴风力发电机具有如下优点:一是安全性高;本发明中风叶脱落、断裂和风叶飞出等问题得到了较好的解决,故安全性高;二是抗风能力强和噪音小;三是回转半径小,在相同发电功率的情况下,本发明具有比其他形式风力发电具有更小的回转半径,节省了空间,提高了转速,同时提高了效率;四是利用风速范围广,在最大限度利用风力资源的同时获得了更大的发电总量,提高了风电设备使用的经济性。此外,本发明还具有结构非常简单,易于维护,可适合大中小型风力发电机;不需对风向,可自适应风向等优点。

 具体实施方式
图例说明:封闭体1;封闭体的侧面11、12、13、14;风口111、112、113、114;风轮轴2;风叶3;框架31;挡风面32;弹性件33;间隙34;风叶轴承35;十字形支杆36;定位线37;定位柱39;风向38;发电机4;导风罩5;挡风片51;盖板15;导风口151;中心轴承152;连接支杆153;风舵6。
  请参见图1和图2,本发明揭示的是一种垂直轴风力发电机的叶片系统,包括一个其横截面为多边形的封闭体1,图1和图2中所示的其横截面的多边形为正方形,实际上,本发明中的多边形也可以长方形,或者本发明中的其横截面的多边形也可以是三边形(正三边形或任意边长的三边形,其它边长的多边形,如五边形,六边形等,只要多边形在12边形以内,本发明均可以实现),在所述封闭体1的每个侧面11、12、13、14上各设有一个风口111、112、113、114,其中风口111为进风口,风口113为出风口,相邻两侧面上的风口处在相同的位置(均处在所在侧面的右侧,显然,风口也可以设计成在所述侧面的左侧的结构),构成一个斜向风流通道,在所述封闭体1内设有一根风轮轴2,在所述风轮轴2上两对风叶3,两对风叶3呈十字形排布,受力的风叶处在斜向风流通道之中,所述风轮轴2的轴心与所述正方形的内切圆的圆心重合,风从进风口111进入,从出风口113吹出,在所述封闭体1内吹动所述风叶3旋转,风叶3则带动所述风轮轴2旋转,风轮轴2进而带动发电机4转动发电,一般情况下,在风轮轴2和发电机4之间会设一个加速装置,因为是现有技术,所以,本图中未画出。本实施例中,所述风叶3包括框架31及挡风面32 ,所述挡风面32设置在所述框架31内,所述框架31与所述风轮轴2固定连接(参见图8)。
  图2所示实施例是对本本发明的一种改进,它是在图1所示实施例的基础上,在每个风口111、112、113、114外侧和设有一个喇叭状的导风罩5,用于引导进风,这种在封闭体的每个侧面上,相对于各自的风口均设有导风罩5的结构,可以使本发明中的封闭体1固定不动,无论风向从哪个方向过来,均可以有效地进入封闭体1内,考虑到风向有可能在从封闭体1的某一个角吹向封闭体1,可以在导风罩5内设一挡风片51,关于这一点,下面会结合其它附图作进一步的说明。
  请参见图3,图3是第二种实施例立体结构示意图,图3所示实施例与图1所示实施例相比,其大体结构相同,所不同的是本实施例中的封闭体1上的盖板15上有导风口151,这时,风轮轴2是通过位于导风口151中心的中心轴承152,以及与中心轴承152固定连接的连接支杆153与盖板15连接的。显然,根据需要,也可以在封闭体1下底设有下盖板,其结构也可以与盖板的结构相同。
  请参见图4,图4是在图3所示实施例的基础上加上导风罩的立体结构示意图。它与图3所示实施例的基本结构相同,所不同是的是在所述封闭体1的每个侧面上设有导风罩5,并且在每个导风罩5内各设有一片挡风片51,所述挡风片将导风罩的内空分隔成两个部分。这样可以实现风向无论如何改变,其导风罩5的导风效果均较良好。本发明中,所述导风罩5的四周侧面可以是平面的或者是弧面的。
  请参见图5,图5是本发明的第三种实施例立体结构示意图,它与图4所示实施例相比,其大体结构相同,所不同的是本实施例中的导风罩5是相互连接的,这样,有利于导风罩5的稳定,显然,这种情况下,也可以及导风罩5内加设挡风片51的结构。
  请参见图6,图6是第四种实施例立体结构示意图,本实施例中,所述封闭体1的横截面在为三角形,这说明,本发明中的封闭体1的横截面不仅可以为正方形,还可以为三角形,以及其横截面可以3至12条边的多边形。
  请参见图7,图7是本发明的第五种实施例立体结构示意图,它是当所述封闭体1上的导风罩5为一个时,可以在所述导风罩5的相对侧设有一个用于调整导风罩方向的风舵6,这时,所述封闭体1可以相对于风轮轴2相对旋转,当风向改变时,风舵6可以随着风向的改变而带动封闭体1及导风罩5方向,使导风罩5总是正对着风向,以获取最大的风量。
  请参见图8,图8是本发明风叶的一种实例的立体结构示意图。所述风叶3包括边框31和挡风面32,所述挡风面32设置在边框31内,所述挡风面32与所述边框31之间用弹性件33连接。这样,当本发明在使用时,风力超过了所设计的风力时,弹性件33就会张开,使挡风面32与边框31之间间隙34增大,泄漏出多余的风量,以达到保持挡风面32受力基本一致的目的。
  显然,本发明中的风叶3也可以设计成包括边框31和挡风面32,所述挡风面32设置在边框31内,并且将所述挡风面32分成至少两个部分,每个部分之间也通过弹性件33相连接的结构,也可以达到泄漏多余风量之目的。
  或者设计成所述风叶3包括边框31和挡风面32,所述挡风面32设置在边框31内,所述挡风面32被分成至少两个部分,每个部分与弹性件33相连,所述弹性件33再与边框31连接的结构。
  请参见图9,图9是本发明风叶的另一种实例的立体结构示意图。如图所示,包括四片风叶3,每片所述风叶3包括框架31及挡风面32,所述挡风面32设置在所述框架31内,所述框架31与两个风叶轴承35(上下各一个)固定连接,所述风叶轴承35设置在所述风轮轴2上,在所述风轮轴2的上端或下端设有十字形支杆36(图中只画出了上面的十字形支杆36,下面十字形支杆未画出),所述风叶3设在十字形支杆36下方,在十字形支杆36的外端设有一根弹性件33,所述弹性件33的另一端与相邻的所述风轮3的外框31相连接;为了保证在无风的情况下,所述风叶3正好处于十字形支杆36的下方,在每个风叶3的另一侧设有两端分别与风叶3和十字形支杆36另一端相接的定位线37,定位线37与弹性件33的拉力平衡,确保风叶3在无风时,正好处于十字形支杆36的下方。显然,本发明中的定位风叶3的方法,除了上述的用定位线37的方法之外,还可以用定位柱39来实现,将定位柱39设置在风叶3上(如图9中的所示),用不同长短的定位柱39来定位风叶3于十字形支杆36的正下方。当然,也可以将定位柱39设置在十字形支杆36上的结构,这时,定位柱39的位置就应该设在风叶3的另一面。本实施例中的箭头38是表风吹的方向的。
  本发明中的弹性件33可以是弹簧或橡皮筋,或者其它具有弹性的材料所做成的弹性件。所述挡风面32所用材料可以为不透风纤维布或可以为不透风无纺布制做。
