Description

外转子式发电机风轮
一、技术领域
本实用新型是涉及一种发电机风轮，特别是一种外转子式发电机风轮。
二、背景技术
随着经济的繁荣与发展，社会用电量急剧增加，缺电少电已是世界性的问题，电能的短缺还有加重之趋势，为开辟新的能源，风能发电为人们所重视，并且已有一定程度的应用。但目前所用的风力发电机多为内转子式，其风轮是装在转子轴上，由于风轮是内转子式风轮，风轮转动力短小，整机散热条件差，不利于风力发电机的发电效率提高，造成能源浪费，而且只能在大风力下工作，供电时间和供电量满足不了人们日常生活中对供电的需要，因此，提供新的风力发电机风轮势在必行。
三、实用新型内容
针对上述情况，本实用新型之目的就是提供一种新型的外转子式发电机风轮，可有效解决风力发电机的发电问题，其解决的技术方案是，风轮壳上装固位支撑，固位支撑外端上装有风轮叶，风轮壳上下壁中心装有轴承，轴承装有带穿线孔或引线槽的固定轴，本实用新型结构简单，易生产和安装使用，改变了现有风轮的安装使用形式，风轮壳既作风叶的支撑面，又为外转子式风能发电机的转子体，外壳风叶是转子的构成部分，散热效果好，贯性大，风轮易于转动，低风速下即可发电，发电效率高，配合储电器，可实现全天候供电，为风能的开发应用开辟了新的光明前景。
四、附图说明
图1为本实用新型的结构主视图。
图2为本实用新型的结构俯视图。
五、具体实施方式
以下结合附图对本实用新型的具体实施方式作详细说明。
由图1所示，本实用新型是风轮壳2上装有固位支撑3，固位支撑3外端上装有风轮叶6，风轮壳2上下壁中心装有轴承7，轴承内装有固定轴4；为了防止灰尘和雨水进入轴承和发电机内，固定轴4上端在风轮壳2上装有上盖1；为其使用安装方便，固定轴4为具有阻磁作用的空心轴或有刻槽5的槽式轴，空心或刻槽5内穿装电流引线；风轮叶6为弧面形或适于转动的其他形状。
使用时，风轮壳构成外转子式风力发动机的外壳式转子组成要件，固定轴与定子绕圈绕阻构成定子，安装于风力发电机固定座上。由其结构可以看出，本实用新型风轮既是风力发电机风轮，又是发电机转子的一部分，结构独特而新颖，风轮由因位支撑和风轮壳(即电机外壳)牢固定位，支撑风叶角度不变，散热效果好，贯性大，非常有利于风轮的转动，在风力发电机上再装配储电器，可实现全天候供电，试用效果非常好，完全可以满足日常生活中室内照明、看电视和工作学习的照明灯及其他家用电器等之用，本实用新型成本低，易生产安装，为风能的开发及风力发电机的普及和使用开拓广阔的市场，经济和社会效益巨大。
还要指出的是，本实用新型不但适用于外转子式风力发电机，还适用于内转子式风力发电机，所不同之是在于风轮固定的形式不同，对于内转子式发电机，本实用新型是直接装在固定轴上的，并非为机壳上，但风轮结构实质是一样的，均是本实用新型的保护范围。
