Description

一种水平叶轮导风型风力发电机
技术领域
本发明属于风力发电技术领域，具体涉及一种水平叶轮导风型风力发电机。
背景技术
目前市场的风力发电机为巨型叶片式，叶片的外径甚至超过30米，对叶片强度要求极高，造价很高，运输，安装及维修都很困难，安装叶片和叶轮的塔柱高达30-40米，甚至更高，其造价和成本显而易见，非常的高昂。而且，在叶轮的运转过程之中，叶轮会产生巨大的紊流，造成巨大阻力，风力利用率不高，往往会低于30％。
发明内容
本发明的目的是解决上述问题，提供一种体积小、成本低、易制造、好维修、风能利用率高的水平叶轮导风型风力发电机。
为实现上述目的，本发明提供如下技术方案：
一种水平叶轮导风型风力发电机，包括支撑框架及其内侧设置的平行于地面的旋转叶轮，所述旋转叶轮的正前方设有坡型挡板，所述坡型挡板包括上部的固定板及中部可移动的滑动板；所述滑动板与其所在的支撑框架平面通过液压升降柱连接并在其推动下上下移动，以调节吹入旋转叶轮的风量大小；所述坡型挡板下方设有漏斗形聚风口，在所述旋转叶轮与漏斗形聚风口之间设有风力导向板，所述风力导向板设于支撑框架内部，其引导风力吹向旋转叶轮上部受力面，避免风力吹向旋转叶轮下部产生阻力。
进一步的，所述旋转叶轮通过中心轴固定于支撑框架上。
进一步的，所述旋转叶轮连接发电机，并在其旋转时带动发电机发电。
进一步的，所述支撑框架下方设有支撑底座。
与现有技术相比，本发明的有益效果在于：
在大约同等发电量的情况下，本发明旋转叶轮外径相比较巨型叶片式风力发电机的超大型叶片，外径估计只有前者的五分之一左右，不需要制造巨型叶片，因此具有易制造、成本低的优势。本设备整体所占空间较小，易于运输，安装和维修方便；极大地减少了紊流，有效合理的引导风向，使得风能利用率大幅提高。
附图说明
为了更清楚地说明本发明实施例技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是为了更清楚地说明本发明实施例或现有技术中的技术方案，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

图2为本发明的右视图；
图3为本发明的后视图；
图4为本发明的俯视图；

具体实施方式
为了使本领域技术人员更好地理解本发明的技术方案，并能予以实施，下面结合具体实施例对本发明作进一步说明，但所举实施例只作为对本发明的说明，不作为对本发明的限定。
如图1-4所示的一种水平叶轮导风型风力发电机，其特征在于，包括支撑框架1及其内侧设置的平行于地面的旋转叶轮2，所述旋转叶轮2的正前方设有坡型挡板，所述坡型挡板包括上部的固定板5及中部可移动的滑动板4，所述滑动板4与其所在的支撑框架1平面通过液压升降柱6连接并在其推动下上下移动，以调节吹入旋转叶轮2的风量大小；所述坡型挡板下方设有漏斗形聚风口8，在所述旋转叶轮2与漏斗形聚风口8之间设有风力导向板9，所述风力导向板9设于支撑框架1内部，其引导风力吹向旋转叶轮2上部受力面，避免风力吹向旋转叶轮2下部产生阻力。
所述旋转叶轮2通过中心轴3固定于支撑框架1上。所述支撑框架1下方设有支撑底座7。所述旋转叶轮2连接发电机图中未示出，并在其旋转时带动发电机发电。
本发明的坡型挡板，上部的固定板5固定不动，中间的滑动板4可上下移动。当风力一般时，滑动板4移动到顶部，这样来风就可以吹到旋转叶轮2的上部，推动旋转叶轮2运转带动发电机发电。在坡型挡板的下方设有一个漏斗形聚风口8，在旋转叶轮2与漏斗形聚风口8之间设有风力导向板9，旋转叶轮2中下部分的来风由漏斗形聚风口8吹入，经风力导向板9引导吹向旋转叶轮2上部的正确受力面，增加推力。这样就可以避免风力吹到旋转叶轮2下部产生阻力，全面的提高风能利用率。
当风力过大，例如台风等来临时，其风力太大会对旋转叶轮2产生过大推力，这样有可能对旋转叶轮2造成损坏。此时可以通过下移滑动板4来减少吹入旋转叶轮2上部的风力，减小其推力，保护旋转叶轮2并保持均衡发电量。
中部的滑动板4及漏斗形聚风口8也可完全封闭，此时旋转叶轮2由于没有风力推动就会处于停止状态，非常方便维修旋转叶轮2及其他相关设备。
在大约同等发电量的情况下，本发明旋转叶轮2外径相比较巨型叶片式风力发电机的超大型叶片，外径估计只有前者的五分之一左右，不需要制造巨型叶片，因此具有易制造和运输，成本低的优势。本设备整体所占空间较小，安装和维修方便；极大地减少了紊流，风能利用率大幅提高。
本发明中未做详细描述的内容均为现有技术。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
