Description

一种风力发电机
技术领域
本实用新型属于可再生能源技术领域,尤其涉及风力发电机。
背景技术
现有的风力发电机都依靠尾舵来实现风向的自适应。
发明内容
本实用新型的目的是提供一种风力发电机,它无需尾舵,也能够实现风向的自适应,同时也能够提高风能转换率。
本实用新型的技术方案是:设置一个喇叭形环形罩,其固连在各个风叶的末端;进一步的,在实施例,环形罩和风叶整体成型。
即:一种风力发电机,包含发电机和固装于发电机转轴的风叶;其特征是:有一个环形罩,其固连在各个风叶的末端。
进一步的,在实施例,环形罩和风叶整体成型。
本实用新型的有益效果:对前述结构进行分析:由于当环形罩的喇叭口和风向相迎时对气流的阻力最小,所以本实用新型能够实现风向的自适应;又由于气流在环形罩的喇叭口内的行程中被逐渐加速,其到达风叶时的速度高于自然风速,叶片和环形罩的转速会更快,使得本实用新型能够输出更多的电能,即能够提高风能转换率;再者,依据陀螺原理和惯性原理,环形罩的旋转(其旋转半径较大),使得转轴和与之固装的旋转体(包括发电机转子线圈、风叶、环形罩)的轴线稳定并且转速平稳,即本实用新型会运行平稳;这既有利于其平稳的提供电力,也有利于延长其使用寿命。
附图说明
下面结合附图和实施例对本实用新型进一步说明。
图1是实施例的立体示意图。
图2是实施例的侧视示意图。
图3是实施例整体成型的环形罩和风叶的示意图。
图中标记说明:
1 发电机   3 环形罩
2 风叶   4 立杆
具体实施方式
一种风力发电机,包含发电机1和固装于发电机转轴的风叶2;其特征是:有一个喇叭口的环形罩3,其固连在各个风叶1的末端。
如图所示,在实施例,环形罩3的小口端部固连在各个风叶2的末端。
进一步的,如图所示,在实施例,环形罩3和风叶2整体成型。
如图所示,发电机1安装在立杆4的顶端。
如图所示,风叶2的个数为5个。其适宜的范围是3~8个。
