Abstract
本发明涉及一种风力发动机装置,其特征在于,它主要包括至少一个风力发动机(2)、用于在风速小时增大吹向风力发动机(2)的风速的构件(3)、以及用于在风速大时影响尤其是减小吹向风力发动机(2)的风速的构件(4)。
Description
本发明涉及一种风力发动机装置。
本发明尤其涉及一种装置,它包括一个风力发动机以及一些用于在风速小的时候增大吹向风力发动机的风速的构件,这些构件至少包括一个第一导风件,该第一导风件沿风吹向风力发动机的方向呈圆锥形缩小。
文献US3883750描述了这种风力发动机装置,但是并未阐述可以根据风速进行最佳调节的解决办法,即并未阐述可以在弱风情况下增大风对风力发动机的作用,而在强风情况下减小所述作用的方法。
本发明旨在提出一种风力发动机装置,这种装置没有上述缺陷,在风速小以及风速大的时候都特别有效。
为此,本发明涉及一种风力发动机装置,它包括一个风力发动机以及一些用于在风速小的时候增大吹向风力发动机的风速的构件,这些构件至少包括一个第一导风件,该第一导风件沿风吹向风力发动机的方向呈圆锥形缩小,其特征在于,这种装置包括一些可以在风力发动机处减小风速或风力的构件,这些构件一方面包括一个与第一导风件的出口相连并沿风吹方向呈圆锥形扩张的第二导风件,另一方面包括一些使风力发动机和第二导风件相互移动的可调节构件,以便风力发动机在第二导风件中滑移远一些或近一些。
为了更好地阐述本发明的特征,下面根据非限制性实施例并参照附图,对本发明作进一步描述。
附图如下:
图1示出本发明的一个风力发动机装置。
如图1所示,本发明的风力发动机装置1主要包括一个风力发动机2、用于在风速小的时候增大吹向风力发动机2的风速的构件3、以及用于在风速大的时候影响尤其是减小吹向风力发动机2的风速的构件4。
用于在风力发动机2处增大风力的构件3包括一个导风件5,该导风件5沿风向W呈圆锥形缩小。
该导风件5主要由一个圆锥形外壳构成,其倾斜度最好小于20度。选择该倾斜度的原因是,导风件5的入口6和出口7的直径差别尤其是直径的减小可以增大吹向风力发动机2的转子8的风速。
用于在风力发动机2处减小风速或实际风力的构件4一方面包括一个直接或间接地与第一导风件5的出口7相连并沿风吹方向呈圆锥形扩张的第二导风件9,另一方面包括一些可以使风力发动机2和第二导风件9相互移动的构件10,以便风力发动机2在导风件9中滑移远一些或近一些。
在图1所示的实施例中,导风件9加以固定,构件10包括一个使风力发动机2安装在其上面的滑车11以及一些使滑车11移动的驱动装置12。
在所示实施例中,驱动装置12由一个或一些可以根据风力发动机的要求而加以自动控制的液压缸组成。显然,在其它变型中,可以通过机械、电动或其它方式进行驱动。
风力发动机2可以通过一个滑车11进行移动,该滑车11可以沿一个滑轨25进行移动。滑轨可以位于导风件9下部,如图1所示。
当然,根据其它变型,风力发动机2可以按固定方式加以安装,而导风件9可以与导风件5一起移动或不一起移动。
要注意的是,风力发动机2的转子直径基本与第一导风件5和第二导风件9之间通风道的直径相一致。
如图1所示,可以配置一个圆柱形连接件13。
要注意的是,入口直径D3小于出口直径D4。
风速小和风速大的时候,风在导风件5中总是增大。因为直径D4大于直径D3,以及风力发动机2可以移动,所以与外部的风相比较,风在风力发动机内可以减小和增大。
如图1所示,导风件5可以配有一个呈圆锥形扩张的导向件14。
整个装置最好可以围绕一个竖直轴15转动,配有一些使之在风中定位的驱动装置16。为此,风力发动机2以及导风件5和9都安装在支承架17上,该支承架17以转动的方式安装在一个固定支承件18-19上。
由图1可以很容易地看出装置的工作情况。
整个装置最好总是迎风安装并通过驱动装置16保持在风中,可以根据一个确定风向的测量装置的数据进行自动控制。
在弱风情况下,风力发动机2定位在连接件13中,即定位在图1所示的右部位置。第一导风件5的圆锥形形状大大增加风力发动机2处的风流量。
一旦风速加大或发生风暴时,风力发动机装置不背离风向而继续工作。在这种情况下,风力发动机2向后移动,即移动到图1中的左部位置。因此,只有导风件5截留的一部分风最终到达风力发动机,使风力发动机2只经受允许的风速。
本发明不局限于上面描述和附图所示的实施例,相反,不超出本发明的范围,这种风力发动机装置可以具有各种不同的形状和体积。
