Description

一种外圈斜拉式多叶片风轮
技术领域
本发明涉及风力设备技术领域，具体地说是把一种风能转化旋转动能的外圈斜拉式多叶片风轮。
背景技术
在现有的风力发电机中使用的风轮一般为三片式叶轮，其结构特点是适用于高速运转的风机，其要求工作风速和起动风速较高，当风速较低时，基本不能使用，且结构较复杂，生产成本较高。
发明内容
本发明的目的在于提供一种外圈斜拉式多叶片风轮，其能充分利用风力资源，在风速较小的情况下也能工作，并且制造成本较低。
本发明技术方案为：外圈斜拉式多叶片风轮包括内毂、叶片、外圈和钢丝，多个叶片通过钢丝斜拉紧在内毂和外圈之间，由此组合而成。
所述的叶片形状为沿径向外大内小长拉梯形。
所述的叶片为30-300片在内毂和外圈上均匀分布。
所述的外圈为一空心管外圈。
所述的钢丝与内毂和外圈连接，在每个叶片上分别通过两组钢丝与内毂和外圈连接。
本发明的风轮能在风力较小的情况下使用，充分利用风资源，并且能降低风力叶片制造的成本，使整个风轮的制造成本大幅降低，其结构紧凑、外形美观，是一种全新结构的新型风轮。
附图说明
图1是本发明的外圈斜拉式多叶片风轮的结构示意图。
图2是图1的侧视图。
图3是本发明的外圈斜拉式多叶片风轮的结构示意图（立体图）。
图中，1―外圈，2―钢丝，3―叶片，4―钢丝，5―内毂。
具体实施方式
 如图1所示，本发明的外圈斜拉式多叶片风轮包括内毂5、叶片3、外圈1和钢丝2、4，多个叶片3通过钢丝2和4斜拉紧在内毂5和外圈1之间，即叶片在外圈和内毂间斜5°拉紧安装，由此组合而成。所述的钢丝与内毂和外圈连接，在每个叶片上分别通过两组钢丝与内毂和外圈连接。所述的叶片3形状为沿径向外大内小长拉梯形。所述的叶片3为30-300片在内毂5和外圈1上均匀分布。所述的外圈1为一空心管外圈。
