Description

垂直轴风车活动风叶
技术领域
本实用新型涉及一种风车部件，特别涉及一种垂直轴风车活动风叶。
背景技术
目前，风力发电行业出现一种垂直轴活动风叶风车，作为关键部件的活动风叶的设计始终没有定型，现有的活动风叶大都按楔形体、旋转轴的基本思路设计成形。其缺点是，楔形体强度差，风叶两侧容易形成风涡流，使风叶在运行中产生颤动；活动风叶两端采用旋转轴结构方式，生产成本高，而且不易维修和更换；风叶自重大，启动风速高，不容易转动。
实用新型内容
本实用新型的目的是针对现有技术存在的不足，提供一种结构简单、重量轻、强度高、转动灵活、便于维修和更换、制造成本低的垂直轴风车活动叶片。
为实现上述目的，本实用新型采用的技术方案是：一种垂直轴风车活动风叶，包括叶片体1和支撑轴2，其特征在于：所述叶片体1的横断面为流线型，位于同一条竖直轴线上的两根支撑轴2分别设置在叶片体1的底部和上部。
本实用新型与现有技术相比具有以下优点：本实用新型设计合理、结构简单、重量轻、强度高、转动灵活、便于维修和更换、制造成本低。
附图说明
图1为本实用新型的结构示意图。
图2为图1的A-A剖视图。
具体实施方式
下面结合附图对本实用新型作进一步的描述。
如图1所示，本实用新型包括叶片体1和支撑轴2。所述叶片体1的横断面为流线型，位于同一条竖直轴线上的两根支撑轴2分别设置在叶片体1的底部和上部。为使本实用新型转动灵活和安装更换方便，在支撑轴2的外端头上设置有顶尖孔3。
如图2所示，为使本实用新型重量轻、强度高，所述叶片体1由设置在叶片体1内部的轻质材料填充体4和设置在叶片体1外部由复合材料制成的外壳5构成。
