Description

风动迎角叶片水平轴风力机
技术领域
本实用新型提供的是风力机械,具体地说是风动迎角叶片水平轴风力机。 
 背景技术
在本实用新型提出以前,水平轴螺旋桨叶片风力机是通过伺服电机调节叶片迎风角,从而实现调速和顺风抵抗大风的破坏,但对于小型风力机来说,伺服电机调整叶片角度结构复杂难以实现。然而,水平轴风力机的叶片角度自动调整是需要解决的问题。 
 发明内容
为了实现风力机叶片角度自动调整,本实用新型提供了风动迎角叶片水平轴风力机。该风力机通过在风叶上连接风叶杆,风叶杆连接风轮轴,且在风叶杆与风叶之间安装角度调整扭力弹簧,解决风叶风动调整迎风角的技术问题。 
本实用新型解决技术问题所采用的方案是:由二至多个风叶通过风叶杆与风轮轴辐射状连接,风叶杆穿插在风叶管内,在风叶管内的风叶杆与风叶之间套装有扭力弹簧。
积极效果,本实用新型通过风动调整叶片角度,实现调速和顺桨。具有结构简单,抗风力强和功率因数高的特点。适宜作为风力机或风力发电机应用。
附图说明
图1为本实用新型风轮结构图 
图2为本实用新型风叶结构图
图3为本实用新型风叶运行状态图
图中,1.风轮轴,2.风叶杆,3.风叶,4.扭力弹簧。
 具体实施方式
据图所示,由二至多个风叶3通过风叶杆2与风轮轴1辐射状连接,风叶杆穿插在风叶管内,在风叶管内的风叶杆与风叶之间套装有扭力弹簧4。 
风叶投影面为矩形。
本实用新型风力机为水平轴风力机类型。
本实用新型工作过程:
当风轮静止时,风叶平面与地面垂直,当风吹向风叶时,由于受到风力的作用,风叶下缘在以风叶杆为轴向远离垂直方向偏转,与风向形成夹角,产生启动升力,在风轮运转的同时,风力相对叶片方向随扭力弹簧的反向作用力保持相应的角度,当风力达到极限时,风力驱使扭力弹簧达到限定的扭转角度,则风叶平面与风向平行,不产生旋转升力,而将迎风面降到最小,从而产生抗风力破坏的作用。
由于本实用新型能够在风力的作用下自动调整风叶角度,从而使风轮保持在适宜的转速下运行,获得较多的风力能量,因而效率高,而且还能够实现顺桨抗风的效果。
