具体实施方式
本发明的核心是公开一种风光发电系统，以达到提高能源利用率的目的。
下面结合附图和具体实施例对本发明作进一步详细描述，但不作为对本发明的限定。
如图1至图6所示，本发明实施例提供了一种风光发电系统，风光发电系统包括支撑架11、光伏叶片20、调整组件30、发电组件40和控制组件。支撑架11具有轴线。光伏叶片20一端铰接在支撑架11的一端，光伏叶片20能够绕支撑架11的轴线转动(本发明实施例中为光伏叶片20能够带动支撑架11一起转动)。调整组件30用于调整光伏叶片20与支撑架11的轴线之间的夹角大小。
设置调整组件30使光伏叶片20既可以作为光伏发电装置使用，也可以作为风机叶片使用，能够充分发挥风光发电互补的特性。
调整组件30设置在支撑架11上并与光伏叶片20驱动连接，调整组件30设置于支撑架11上并能够沿支撑架11的轴线方向移动。具体地，调整组件30与光伏叶片20铰接。
本发明实施例中，调整组件30可以将光伏叶片20固定在水平位置和竖直位置之间的任何位置。
风光发电系统还包括安装架12，安装架12的一端与支撑架11的一端铰接，安装架12的另一端与调整组件30铰接，光伏叶片20固定在安装架12上。本发明实施例中，上述光伏叶片20随着安装架12一起相对于支撑架11摆动，从而实现光伏叶片20与支撑架11的轴线之间的夹角调节。
如图1所示，本发明实施例中的调整组件30包括驱动组件、调整丝杠31、螺母组件和伸缩架32。调整丝杠31同轴设置在支撑架11内。驱动组件与调整丝杠31连接，驱动组件能够驱动调整丝杠31相对于支撑架11转动。螺母组件设置在调整丝杠31上并能沿调整丝杠31的轴线方向移动。伸缩架32的一端与螺母组件铰接，伸缩架32的另一端与光伏叶片20(安装架12)的另一端铰接。
当驱动组件驱动调整丝杠31转动时，螺母组件相对于调整丝杠31轴线方 向上下移动，从而带动伸缩架32的一端一起上下移动。当螺母组件由调整丝杠31的下端向上移动时，伸缩架32向上撑开，使光伏叶片20的另一端远离支撑架11。当螺母组件由调整丝杠31的上端向下移动时，伸缩架32向下回缩，使光伏叶片20的另一端靠近支撑架11。
需要说明的是，当光伏叶片20在风力驱动下带动支撑架11转动时，上述调整丝杠31、螺母组件和伸缩架32均能够随光伏叶片20一起转动，即在风力驱动下，调整丝杠31、螺母组件、伸缩架32与支撑架11不发生转动。
优选地，光伏叶片20为多个，沿支撑架11的周向间隔均布，伸缩架32也为多个，每个伸缩架32的一端均与螺母组件铰接，每个伸缩架32的另一端均与对应的光伏叶片20的另一端铰接。将多个伸缩架32的另一端均铰接固定在螺母组件上，能够保证上述多个伸缩架32的撑开和收缩同步。
本发明实施例中，螺母组件包括丝杠螺母34和螺母套座35，螺母套座35固定在丝杠螺母34上，丝杠螺母34能够带动螺母套座35一起相对于调整丝杠31轴向移动，上述多个伸缩架32的一端均铰接在螺母套座35上。螺母套座35的直径大于调整丝杠31的直径，使螺母套座35与调整丝杠31之间存在滑动间隙。
优选地，调整丝杠31外套设有第一伸缩防尘罩61和第二伸缩防尘罩62，第一伸缩防尘罩61一端与支撑架11的一端固定，第一伸缩防尘罩61的另一端与螺母套座35固定。第二伸缩防尘罩62的一端与支撑架11的另一端固定，第二伸缩防尘罩62的另一端与丝杠螺母34固定。上述第一伸缩防尘罩61和第二伸缩防尘罩62均可以随着螺母组件一起沿调整丝杠31轴向伸缩。设置第一伸缩防尘罩61和第二伸缩防尘罩62能够有效防尘。
进一步地，驱动组件为步进电机33，步进电机33包括输出轴和壳体，输出轴与调整丝杠31固定连接，壳体的一端与支撑架11固定连接，壳体的另一端与发电组件40固定连接。
当需要调整光伏叶片20的位置时，步进电机33驱动调整丝杠31对应转动，从而使螺母组件沿竖直方向上下移动，进而在伸缩架32的作用下改变光伏叶片20的位置。同时，由于步进电机本身具有自锁功能，当上述光伏叶片20在风力作用下带动支撑架11转动时，可以使步进电机整体一起转动。由于 步进电机的壳体与发电组件40连接，当光伏叶片20转动时，可以实现发电。
本发明实施例中，发电组件40包括定子41、转子42和底座43，定子41固定在底座43上，转子42套设在定子41内，壳体的另一端与转子42固定连接。
优选地，在底座43处可以设置有蓄电池，用于存储电能。上述底座43上还可以设置有逆变器和供电接口，用于为其他设备充电。支撑架11的一端上设置有指示灯50，可以作为照明灯或者故障报警灯使用。
如图7和图8所示，上述控制组件包括辐射传感器、风向风速传感器、位置控制器、太阳能控制器(MPPT控制器)、逆变器(DC/AC)和风光补偿器。由于上述部件均是现有技术，上述部件的具体结构以及连接关系此处不再赘述。
本发明实施例中，风力发电和光伏发电分别通过MPPT控制器，并在风光补偿器中实现合并，所产生的电能既可以储存在蓄电池中或直接用于直流负载，又可以通过DC/AC并入电网或用于交流负载。底座上设有插座，可以为手机、电动车等设备充电，系统相当于一个充电站，可以实现发用电一体化功能，整体系统的电能控制策略如图所示。除此之外，整体系统还具有一定的美观性，可以用于公园、沙滩等区域的观景物。
本发明实施例具有以下工作模式：
1、纯光伏发电模式
无风光照良好环境下，光伏叶片20可以通过伸缩架32伸缩完全展开(如图1和图2)，光伏叶片20呈平铺状态，风光发电系统相当于一个光伏棚，可以遮阳、挡雨，提供休息场所。此时，风光发电系统是纯光伏发电的工作模式，光伏所产生的电能可以并入电网或储存在蓄电池当中。同时，辐照传感器和风向风速传感器采集的数据可以实时反馈给位置控制器，位置控制器对步进电机33进行控制，步进电机33带动调整丝杠31旋转，使得丝杠螺母34直线运动，从而改变光伏叶片20的夹角，实现光伏板的夹角可根据光照情况自动调节的功能，增加了光伏发电的效率，控制策略如图6所示。
2、风光互补发电模式
如图3和图4所示，有风且光照良好的环境下，光伏叶片20同样可以通 过位置控制器对步进电机33的控制策略进行夹角的调节。此时，光伏叶片可相当于风机的叶片，风作用于光伏叶片20上，光伏叶片20带动转子42绕着定子41旋转，产生电能，如图3和图4所示。此时，光伏叶片20不仅可以作为光伏发电装置，同时通过调整光伏叶片20位置状态变换为风机的叶片进行风力发电，充分发挥了风光发电互补的特性。
3、纯风力发电模式
如图5和图6所示，有风但光照不好的环境下，尤其是夜间和阴雨天，光伏叶片20可以通过伸缩架32完全收缩，如图5和图6所示，光伏叶片20呈竖直状态，类似风机的叶片且迎风状态最佳。此时，系统处于纯风力发电的工作模式，弥补了单纯光伏发电设备在夜间和阴雨天无法发电的问题，风力发电所产生的电能同样可以并入电网或储存在蓄电池当中。
当然本发明并不限于上述实施例，例如在一种未图示的实施例中，调整组件包括液压驱动组件和伸缩架，液压驱动组件与支撑架同轴设置，液压驱动组件包括活塞杆；伸缩架的一端与活塞杆铰接，伸缩架的另一端与光伏叶片的另一端铰接。在该实施例中，除上述结构外，其他结构以及工作原理均与在先实施例中相同，此处不再赘述。
当然，在另外一种实施例中，还可以采用气压驱动替代上述实施例中调整丝杠31和螺母组件的配合形式。
本发明实施例中的风光发电系统可以用于光伏路灯、光伏广告牌或者光伏棚等。在实际应用时，可以根据不同应用环境适当增加防尘、防水等组件。
以上对本发明所提供的柜体母线供电连接密封结构进行了详细介绍。本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也落入本发明权利要求的保护范围内。
