所述风向传感器和风速传感器分别用于采集风向数据和风速数据，所述控制器设有风速阈值和风速上限阈值。当风速达到风速阈值时，所述控制器根据风向控制电动伸缩杆2和电机4输出轴旋转，调节光伏板7方向，本实施例中当风速达到风速阈值时，控制器根据风向数据控制光伏板7与风向平行，减少光伏板7所受风的阻力，降低光伏板7在大风天气中被破坏或吹走的概率。当风速达到风速上限阈值时，所述控制器还用于控制光伏板7与底座1平行，并控制电动伸缩杆2收缩，降低光伏板7高度，使得光伏板7尽可能贴近底座1，避免因电动伸缩杆2过长，在风中因摇摆幅度过大而断裂的情况，提高了装置在风中的稳定性。
还包括储电模块，所述储电模块与控制器、风向传感器、风速传感器、光照传感器、电量检测模块、温度检测模块、湿度检测模块、显示模块、通信模块、电机4和电动伸缩杆2均电连接以供电，本实施例中的储电模块设于底座1内部，采用12V200AH锂电池一块。
所述电量检测模块用于检测储电模块的电量信息，所述温度检测模块和湿度检测模块分别用于检测温度数据和湿度数据。采集的电量信息、温度数据和湿度数据均通过显示模块进行显示，并通过通信模块上传至服务器。本实施例中的显示模块采用液晶屏，所述液晶屏嵌设于底座1上表面。
所述光照传感器用于检测光伏板7当前方向的光照信号，所述光照信号还通过通信模块上传至服务器，以便用户远程监测光伏板7朝向的光照信号强度，本实施例中的光照传感器设于光伏板7上表面；所述控制器还用于根据光照传感器的光照信号强度，通过电机4调节光伏板7方向。本实施例中，控制器根据光照传感器的光照信号强度，通过控制电机4使得光伏板7面向光照信号强度最强的方向，使得光伏板7能够面向阳光更为充足的一面，提高太阳能的转化效率。
实施例二
实施例二基本如附图2所示，实施例二与实施例一的区别仅在于，实施例二中还设有板面清洁机构，所述板面清洁机构包括清洁组件、传动机构和蓄水箱；所述传动机构包括传动链11、传动轮8组和驱动电机，所述传动轮8组包括于光伏板7两端对称设置的传动轮8， 所述驱动电机用于驱动传动轮8转动，同一侧的传动轮8外围连接设置传动链11，于任一端传动轮8之间设置布轴；所述清洁组件包括清洁板和连接水管；所述清洁板包括防护层10和清洁层9，防护层10与清洁层9之间设有空腔，所述清洁板侧面设有连接水管，所述空腔与蓄水池通过连接水管连通，所述清洁板整体采用柔性材质，清洁板一端与布轴固定连接，所述清洁板的另一端的两侧与传动链11固定连接，通过传动轮8的不同方向的转动，清洁板既能随着传动链11覆盖光伏板7板面，也能随着传动轮8的转动缠绕于布轴表面，清洁板覆盖光伏板7板面时，清洁层面向光伏板7。所述清洁层9外表面呈波浪状，其表面设有毛刷，与光伏板7板面相接触的弧形顶端设有出水孔，出水孔处设有单向阀。
当风速达到风速阈值时，所述驱动电机驱动传动轮8转动，从而展开清洁板，当风速低于风速阈值时，所述驱动电机驱动传动轮8转动，收起清洁板。
具体实施时，在清洁板展开过程中，清洁板内部空腔被舒展开，在负压作用下，蓄水池中的水被吸到空腔中；待清洁板完全展开后，清洁层9外表面与光伏板7之间形成空气通道，当强风吹过时，因通道的宽窄变化，通道内的压强也不同(伯努利原理)，因出水孔设置于清洁层9外表面与光伏板7板面相接触的弧形顶端，所以清洁板内部空腔中的水在负压作用下被吸出，从而起到对光伏板7板面的清洁作用；此外，因清洁层9整体采用的柔性材质，所以清洁层9外表面会在风力作用下产生一定的波动变形，从而使得其表面的毛刷能够对光伏板7板面进行刷洗，进一步提高其清洁效果。
以上的仅是本发明的实施例，方案中公知的具体结构及特性等常识在此未作过多描述，所属领域普通技术人员知晓申请日或者优先权日之前发明所属技术领域所有的普通技术知识，能够获知该领域中所有的现有技术，并且具有应用该日期之前常规实验手段的能力，所属领域普通技术人员可以在本申请给出的启示下，结合自身能力完善并实施本方案，一些典型的公知结构或者公知方法不应当成为所属领域普通技术人员实施本申请的障碍。应当指出，对于本领域的技术人员来说，在不脱离本发明结构的前提下，还可以作出若干变形和改进，这些也应该视为本发明的保护范围，这些都不会影响本发明实施的效果和专利的实用性。本申请要求的保护范围应当以其权利要求的内容为准，说明书中的具体实施方式等记载可以用于解释权利要求的内容。
