Description

双活叶齿轮连动风力机
技术领域  风力发电。
背景技术  本人已申报，申请号200410075017X的风力机不适合生产家庭用小型风力机，而且轨轮长期在轨道上运行易出现啃轨，运行稳定性差。
发明内容  本发明任务是提供适合生产大、中、小型风力机，而且适用于双活叶有机连在一起运行稳定可靠的方案。
为实现本发明任务，采用每个活叶都安装一个齿轮，齿轮以活叶轴为轴心，齿轮与活叶绕活叶轴同步往复转动，往复转动角小于90度。齿轮啮合连接把双活叶有机连在一起，安装在双活叶上二齿轮有时不能直接连接，连接需要用过渡齿轮一对或二对，直接安装在活叶上的齿轮一般扇形齿轮即可，同一双活叶上的对应齿轮相同，转动方向相反。风力机大小不同，风力机安装双活叶组数不同，齿轮安装的位置和方法有多种。
采用棘轮原理调控双活叶，每一双活叶都安装棘轮或棘爪，双活叶与棘轮或棘爪同时往复转动，通过控制棘爪或棘轮来控制双活叶，最后达到控制风力机工作。
采用副支杆，风力机安装3至6组双活叶时，根据齿轮安装位置需要加装副支杆，横支杆连接在风叶杆靠近外端，副支杆一端连接在风叶杆上并垂直于风叶杆，另一端连接在横支杆上。
双活叶齿轮连动风力机工作，阻风面迎风，双活叶阻风面有一张开夹角，双活叶顺风张开顺风运行，如张开活叶夹阻风，双活叶带动齿轮、棘轮或棘爪转动，双活叶张开到最大角时接触弹性减震挡板。齿轮连接把双活叶有机连在一起。泄风面迎风，双活叶顺风折起，如折起的活页夹逆风运行，双活叶泄风夹角到设定值时泄风回位弹簧工作，使双活叶泄风后有一张开夹角。风力机双活叶不断交替阻风、泄风带动风力机转动，风力机将动力传递给发电机或其它用能机械。
双活叶齿轮连动风力机，若是采用活叶安装棘轮，在运转中需要停机，拉动控制绳拖动棘爪控制板，泄风回位弹簧移到非工作位，棘爪放在棘轮上，棘爪与棘轮的作用下双活叶泄风后再阻风不能张开，风力机停止工作。若需要恢复风力机工作，放回控制绳，棘爪控制板在回作弹簧作用下退回原位，把棘爪从棘轮上推起，泄风回位弹簧回到工作位推开双活叶有一张开夹角，阻风面迎风的双活叶顺风张开顺风运行，风力机恢复工作。
本发明双活叶齿轮连动风力机，采用齿轮连接带动双活叶显现出巨大优点，双活叶阻风、泄风不易出现故障，双活叶折动轻快，运转稳定可靠。适宜生产大、中、小型风力机，结构简单合理，工艺简单成本低，适应环境范围广，风叶不易损坏，操作控制简单，安装维护方便，易于推广应用。
附图说明    图1是三组双活叶齿轮连动风力机示意图。
            图2是齿轮连动双活叶示意图。
具体实施方式  已知部分省略，在每根风叶杆泄风面横支杆处安装可调弹性减震挡板，双活叶最大阻风夹角要小于170度。在风叶杆[1]头外，双活叶[2，3]框上装有钢板，钢板面与双活叶[2，3]面互相垂直，齿轮[4，5]棘轮[6，7]分别以活叶轴为轴心安装在钢板上，齿轮[4]与齿轮[5]连接。棘爪板安装在平行于棘轮[6，7]外面用螺栓固定在风叶杆[1]头上，棘爪板上可滑动的棘爪控制板与控制绳连接。
棘爪板为钢板装有一对弹簧板，一对棘爪，上下一对滑道，还有回位弹簧与棘爪控制板连接，滑道上装有可往复滑动的棘爪控制板。棘爪控制板上有一对棘爪控制弹簧，一对泄风回位弹簧。棘爪控制板在弹簧作用下靠近棘轮位置时，棘爪控制弹簧推起棘爪与棘轮分开，泄风回位弹簧使双活叶泄风后有一张开夹角。拉动控制绳棘爪控制板沿滑道远离棘轮位置时，泄风回位弹簧到非工作位，双活叶泄风后没有张开夹角，棘爪放在棘轮上，双活叶泄风后再阻风不能张开。
齿轮也可以安装在风叶杆的阻风面或泄风面，若在阻风面安装齿轮，双活叶的轴安装在风叶杆阻风面，需要安装2对齿轮。同理齿轮可安装在风叶杆泄风面。
