Abstract

一种低速风力发电，塔架上端的塔头2上，固定主轴1(不转动)，和装有发电机M；主轴1外伸部位以轴承装置能自由转动的风轮轮毂3，轮毂3上设置内外轴座3a和5a，辐档4、腰圈5及齿圈6，齿圈6与发电机M的齿轮7啮合，这样达到了只用单级齿轮发电的目的。特点是以轮毂联体的钢齿圈6等等既是增速大齿轮又是增强低速风轮的结构件，有突破风叶轮大直径化瓶颈之优点。

Description

低速风轮发电
本发明属于风力机领域，一种低速风轮发电技术。
风力发电现有技术都用高速风力机、特别是三叶风力机。低速风力机仅仅用于提水等等，因为要与发电机转速相匹配，即使高速风力机也必须用增速齿轮箱，欧洲正在研究改革掉故障不算太少，昂贵而笨重的齿轮箱，但以目前水平，发现不用齿轮箱的风力发电机，要用多极而体积庞大、笨重而造价高。
本发明之目的：仅用一级增速齿轮，即使低速风力机也可实现发电，尤其中国好些内陆地区的风速V＜3m/s，现有技术的高速风力机难以起动，但低速风力机的实度大，起动风速小，假如设法能应用成功风力发电，则也是节约资源利用。
图1，①改变现有低速风轮结构和加大风轮直径D；②主轴1不传递扭矩，只起了支承风轮回转中心的作用；③以风轮的腰圈5外层的齿圈6直接驱动发电机M。
图1的序列号说明：1是主轴，紧固在塔头2上，3是轮毂，在主轴1的外围上以轴承装配成可自由转动，4是辐档(3-4档)，5是腰圈(外圈上是镶有钢齿圈6)，6是钢齿圈，7是发电机齿轮，M是发电机，3a是内叶轴座，8是内叶片，5a是外叶轴座(轴座盖可卸)，9是外叶片，5b是张拉线(高强度钢园条)。
塔头2在H高度段是流线型截面，在H的下界线处，有偏航装置可使风轮对准上风向；再往下是圆锥筒固定体。
轴毂3的左端是内叶轴座3a，右端是辐档4，联在一体的腰圈5和外叶轴座5a，这些都是用轻金属合金铸成整体，或用环氧树脂E-51及E-502#为固化剂，以碳纤维和高强度玻璃纤维增强的复合材料制成，更为理想。
钢齿圈6是机械加工后镶套在腰圈5的外圈上、构成了轴毂3的突出作用：①联合整个风轮的腰圈5及张拉线5b、强化了风叶轮结构，有利于向大直径风轮发展；②在整个风轮的腰圈5部位(通过钢齿圈6)的大扭矩的集合圈上、能量输出给发电机，改变了现有技术的风轮长叶片的大力矩——弯曲应力集中在叶根和轴毂处的缺点；③只用单级齿轮增速就解决了发电机发电，并省去了机舱。
图3是齿轮副的防雨雪，防尘图：A是圆环板，在右侧平面上有凸檐A1和A2(也是环形同心圆)，在发电机齿轮轴处开有一缺口，圆环板A是静止的在缺口以外的上下凸檐A1和A2之间都是实腹，在实腹环形平面上设置数个支撑点，用悬伸臂和弯臂与图1的塔头2连接固定。B是内防尘罩，B1是凸檐，C是外防尘罩，C1是凸檐，7是发电机齿轮，M是发电机，6是钢齿圈，5是腰圈，5a是外叶轴座。

Claims (3)

1、一种低速风轮发电，以风轮轮毂通过辐档、张拉线强化的腰围、钢齿圈和外叶轴座支撑，强化了风轮结构和功能——直接以腰围、钢齿圈输出风轮能量给发电机轴齿轮驱动发电。
2、根据权利要求1所述的低速风轮发电，特征是风轮能量不再是通过主轴、齿轮增速箱输给发电机发电。
3、根据权利要求1或2所述的低速风轮发电，特征是风轮的叶片中段受到支撑和输出风轮动能给发电机。
