Abstract

一种风力机活门式叶片，它有一叶片框架，该叶片框架成方格状，每个方格上都设有单扇或双扇单向活门。本实用新型设计新颖，结构合理，其前面活门关闭，迎风面积大，产生的推动力大，后面活门开启，迎风面积小，风阻小。因此前面推动力与后面风阻比大，风能利用率高，叶轮的转速快，启动速度低。

Description

一种风力机活门式叶片
技术领域：
本实用新型属风力机械技术范围，涉及一种新型的风力机叶片。
背景技术：
风力机叶片是风力机非常关键的部件之一，良好的设计、可靠的质量和优越的性能是保证风力机组正常稳定运行的决定因素。现有技术的风力机叶片，其形状一般都是固定的，叶片平面与风向之间存在有一定的夹角，叶轮主要靠风力作用于叶片平面所产生的侧向分力推动而旋转。在叶轮旋转过程中，由于叶片后面的风阻面积与前面侧向分力所作用的面积相等，尽管后面相对风力较小，但仍存在有较大的风阻。致使前面旋转推动力与后面风阻比小，造成风能利用率低，叶轮的转速低，启动速度高。
发明内容：
本实用新型的目的是提供一种新型的风力机活门式叶片，用以有效地克服现有技术所存在的上述弊端。本实用新型的目的是以如下技术方案实现的：它有一叶片框架，该叶片框架成方格状，每个方格上都设有单扇或双扇单向活门。
本实用新型设计新颖，结构合理，其前面活门关闭，迎风面积大，产生的推动力大，后面活门开启，迎风面积小，风阻小。因此前面推动力与后面风阻比大，风能利用率高，叶轮的转速快，启动速度低。
附图说明：
图1是本实用新型活门关闭状态下的前面结构示意图
图2是本实用新型的活门开启状态下的结构示意图
具体实施方式：
附图给出了本实用新型的一个具体实施例，根据图1、图2所示，图中1是叶片框架，该叶片框架1成方格状，每个方格上都设有双扇单向活门2。
