具体实施方式
现在结合附图对本发明作进一步详细的说明。这些附图均为简化的示意图,仅以示意方式说明本发明的基本结构,因此其仅显示与本发明有关的构成。
如图1-4所示,一种具有自动调节功能的太阳能发电装置,包括太阳能电池板1、衔接装置、支撑装置2、底座3和光向测量盒4,所述衔接装置设置在太阳能电池板1的下方,所述支撑装置2设置在底座3上并通过衔接装置与太阳能电池板1滑动连接,所述光向测量盒4固定在太阳能电池板1的一侧;
所述衔接装置包括托盘7和若干螺丝5,所述托盘7通过螺丝5固定在太阳能电池板1上,所述托盘7为圆形,所述托盘7上设有以托盘7圆心为中心均匀分布的三条凹槽6;
所述支撑装置2包括底板9和三个支撑单元,所述支撑单元包括液压千斤顶8、管道10和压力泵11,所述液压千斤顶8通过管道10与压力泵11连接,所述液压千斤顶8设置在底板9的上方,所述管道10和压力泵11均设置在底板9的下方,所述液压千斤顶8的数量与凹槽6的数量一致且一一对应,所述液压千斤顶8通过对应的凹槽6与托盘7滑动连接;
所述光向测量盒4包括外壳12,所述外壳12上设有透光镜13,所述外壳12的内侧设有红外线探测器14、吸光材料15和反光镜16,所述透光镜13和反光镜16所在直线与外壳12的中心轴线在同一直线上;
所述底座3内设有中央处理器,所述压力泵11和红外线探测器14均与中央处理器电连接。
作为优选,为了保证压力传输的密封性,所述压力泵11为油压泵。
作为优选,为了提高吸光材料的吸光性从而保证红外线探测器14监测的准确性,所述吸光材料15的外表为黑色。
作为优选,为了保证光线能照射到光向测量盒4的底面,所述光向测量盒4的长度和宽度均为高度的20倍。
作为优选,为了提高光向与光向测量盒4底面垂直判断的准确性,所述透光镜13和反光镜16的直径均为1毫米。
作为优选,为了方便连接,所述红外线探测器14与中央处理器无线连接。
太阳能发电装置工作时,太阳光通过透光镜13照射到光向测量盒4内部,当光线与光向测量盒4内部底面不是垂直关系时,太阳光照射到底面的吸光材料15上,在吸光材料15的被照射处形成一块亮斑,光向测量盒4内部的红外线探测器14探测到亮斑的位置,将该外置信息传递给中央处理器,中央处理器通过位置信息和透光镜13位置计算出光线传播方向并获得光向与太阳能电池板 1之间的夹角,依次调节支撑装置2中的三个压力泵11中的压力,通过管道10与压力泵11连接的液压千斤顶8中的压力也发生改变,从而形成液压千斤顶8高度发生变化,根据不共线的三点确定一个平面这一原理,与液压千斤顶8顶部滑动连接的托盘7所在平面角度发生改变,从而带动太阳能电池板1和与太阳能电池板1固定连接的光向测量盒4所在平面角度发生改变。
当太阳能电池板1所在平面角度调节到与光线垂直时,光线也同时垂直照射到光向测量盒4的反光镜16上,通过反光镜16将光线全部反射出光向测量盒4外,红外线探测器14监测不到光斑位置信息,中央处理器停止对压力泵11的调节命令,整个调节工作完成,此时可实现太阳能电池板1对阳光的最大化吸收,从而提高发电效率。
与现有技术相比,该具有自动调节功能的太阳能发电装置通过红外线探测器14监测光线通过透光镜13投入到吸光材料15的位置,将位置信息传递给中央处理器后,中央处理器计算太阳能电池板1与光线的当前夹角,并调节液压千斤顶8的高度,改变太阳能电池板1角度,保证光线垂直照射到太阳能电池板1上,从而实现光能的最大化吸收提高发电效率。
以上述依据本发明的理想实施例为启示,通过上述的说明内容,相关工作人员完全可以在不偏离本项发明技术思想的范围内,进行多样的变更以及修改。本项发明的技术性范围并不局限于说明书上的内容,必须要根据权利要求范围来确定其技术性范围。
