Description

大型帆式风力机
本实用新型属于发电设备技术领域，涉及一种风力发电设备的改进。
目前，作为风力发电设备一般分为两大主要部分，一是发电机部分，另一是风力机部分，现有的风力发电的风力机均采用涡轮式，其发电的功率取决于风力机上的风轮直径(p＝D2/10)，直径越大，功率越大，而直径越大对风轮材质的要求越高，制造工艺越难；因此要想生产大功率的风力机就受到一定的限制。另外涡轮式风力机是靠升力获得旋转动力，效率不高。
本实用新型的目的是提供一种可用于大功率发电、运转效率高的大型帆式风力机。
本实用新型的技术方案如下：
在立式转轴上固定有三—四个帆叶，三个帆叶之间的相互夹角为120度，四个帆叶之间的相互夹角为90度，在帆叶框上纵向固定有数个至数十个立轴，每个立轴上有可转动的小帆叶，并且小帆叶的另一边能搭接在相邻的立轴上，使小帆叶只能在180度范围内转动。
本实用新型的优点是：结构简单、制造技术要求低；现有的风力机风轮是靠升力获得动力，而该风力机是靠风帆的阻力获得动力，适宜大型的风力发电，利用风力效率高。
图2是本实用新型的仰视示意图。
下面结合附图对本实用新型做进一步描述：
其中：1是立式转轴、2是帆叶、3是帆叶框、4是立轴、5是小帆叶。
当A帆叶与风向呈90度角时，A帆叶上的小帆叶处于搭接闭和状态，风力推动A帆叶带动另两个帆叶及立式转轴顺时针旋转(图2所示)，此时B、C帆叶上的小帆叶处于打开和半打开状态，B、C帆叶不产生动力，经旋转120度后，C帆叶与风向呈90度角时，C帆叶上的小帆叶处于搭接闭和状态，风力推动C帆叶带动另两个帆叶，及立式转轴顺时针旋转，以此不间断地带动立式转轴循环转动。
