Description

一种具有较高风能利用效率的垂直轴风力发电机
技术领域
本发明涉及一种发电装置，特别是一种高效率垂直轴风力发电机，属风力发电技术领域。
背景技术
风力发电机根据主轴安装方位分为水平轴和垂直轴，迄今为止应用较为普遍的是水平轴风力发电机。水平轴发电机尽管应用普遍，但结构上存在一些问题，如：需要偏航、对桨等迎风和控制迎风面增大阻力差的结构，这使发电机的结构复杂、占用零部件多且容易造成故障。基于水平轴发电机的结构缺陷，近年来，垂直轴发电机技术发展迅速，应用日益广泛。垂直轴发电机可通过对叶片结构的优化设计，增大风阻力，提高风阻力差，使风机即使在较低的风速下仍可以正常启动运行，无需偏航、变浆装置，因而结构相对简单。垂直轴发电机关键技术是叶片结构的设计，叶片形状优劣直接影响其启动性能和风能利用效率。目前，垂直轴发电机存有升力型叶片自起动性能差、低风速发电性能差，阻力型风能利用效率低等问题，因此优化叶片结构是解决上述问题的关键所在。
发明内容
本发明用于克服已有技术的缺陷而提供一种能量转换利用率高、低风速发电性能优良的具有较高风能利用效率的垂直轴风力发电机。
本发明所称问题是由以下技术方案解决的：
一种具有较高风能利用效率的垂直轴风力发电机，构成中包括中心柱、叶片和横撑杆，各叶片垂直设置，它们相对中心柱轴线均匀分布，叶片由横撑杆连接中心柱，其特别之处是：所述各叶片的截面形状相同，所述叶片截形的一侧为钩状端、且钩状端朝外设置。
所述叶片截形轮廓由O-Q、O-R、P-Q、P-R四条曲线组成，四条曲线由下述参数确定：
建立平面直角坐标系，以所述截形的一端为坐标原点，各曲线上相应点的坐标值如下：

具体实施方式
参看图1、图2，本发明是一种对叶片及横撑杆进行全新设计的垂直轴大风力发电机，其构成中包括中心柱1、叶片3和横撑杆2，各叶片垂直设置，它们相对中心柱轴线均匀分布，叶片由横撑杆连接中心柱。本发明叶片3的截面形状与横撑杆2的截面形状相同，叶片截形的一侧为一钩状端3-1，叶片及横撑杆安装时，叶片钩状端的钩部朝外设置、横撑杆钩状端的钩部端朝上设置，叶片的钩状端端部与叶片的钩状端端部接合。本发明风机叶片数目≥2，图示为5叶片，叶片通常使用2-12片。
参看图3，本发明叶片2及横撑杆的截形轮廓由O-Q、O-R、P-Q、P-R四条曲线组成封闭曲线，其中O点和R点为截形的两个端点。上述四条曲线由下述参数确定：参看图4，建立平面直角坐标系，以所述叶片及横撑杆截形轮廓的一端O点为坐标原点，将各曲线由相应X、Y值确定的坐标点用光滑曲线连接，即得到叶片及横撑杆截形轮廓曲线。上述X值和Y值具有相同的长度单位。
上述截形轮廓曲线是经过对叶片、横撑杆翼型气动性能研究、计算、模拟和反复试验得出，采用该叶片、横撑杆翼型，可以明显增大风阻力，提高风阻力差，尤其是在较低风速下的发电能力可以大幅度提高。以下给出一组对比数据：
