请结合参考图1和图2，本申请提出一种光伏支架100。
在本申请的一实施例中，该光伏支架100包括支撑柱10、回转减速器33、承载架50以及伸缩组件70；其中，回转驱动系统30设于支撑柱10；承载架50连接于回转驱动系统30，回转驱动系统30驱动承载架50相对于支撑柱10转动，承载架50用以安置太阳能光伏板300；伸缩组件70连接于支撑柱10和承载架50，并可使承载架50限位固定于支撑柱10。
在本申请的一实施例中，支撑柱10主要用于支撑承载架50，其可以是固定于地面混凝土桩，也可以是固定于螺旋桩上，并可通过螺钉进行锁紧，以保证支撑柱10安装的稳定性。为了便于支撑柱10的安装固定，支撑柱10的底端可以设有连接盘，并在该连接盘上设有供螺钉穿过的腰型孔。而为了提高该连接盘和支撑柱10的连接强度，可以在支撑柱10和连接盘的连接处设有至少两个加强筋。至少两个加强筋围绕连接盘的中心呈均匀间隔分布，以避免造成应力集中。进一步地，为了提高支撑柱10的支撑效果，光伏支架100可以包括两个、三个或者更多个支撑柱10，且每一个支撑柱10均与承载架50连接。承载架50主要用于安置太阳能光伏板300，其与支撑柱10转动连接。回转驱动系统30即为电机31和回转减速器33的组合，回转减速器33内设有蜗轮蜗杆机构或者齿轮组机构。回转驱动系统30主要用于提供动力，以驱动承载架50相对于支撑柱10转动，完成置于承载架50上的太阳能光伏板300对太阳的照射范围的跟踪。同时，在光伏支架100受到较大的气流冲击时，回转驱动系统30可以通过自身的自锁功能实现对承载架50限位固定，避免承载架50发生晃动而影响置于承载架50上的太阳能光伏板300安装的稳定性。其中，回转驱动系统30可以先将承载架50驱动至水平状态 ，以降低气流对光伏支架100的冲击效果，再通过自锁对承载架50进行限位固定；而回转驱动系统30的自锁功能可以是通过内部的蜗轮蜗杆机构或者齿轮组实现，由于回转驱动系统30为现有技术，故在此对其工作原理不作详述。进一步地，为了便于对回转驱动系统30的维修更换，回转驱动系统30可以是可拆卸地连接于支撑柱10。具体地，可以是通过螺钉、卡扣或者磁铁的方式进行可拆卸固定。承载架50主要用于安置太阳能光伏板300，并在回转驱动系统30的驱动下带动太阳能光伏板300转动，实现对太阳的照射范围的跟踪。其中，承载架50和支撑柱10可以是呈一体结构，以提高两者连接的稳定性。当然也可以是呈可拆卸地分体结构，以便在承载架50发生损坏时可以将其拆卸而进行维修更换。
本申请的技术方案的光伏支架100用于安装太阳能光伏板300时，将太阳能光伏板300安置于承载架50上，通过回转驱动系统30驱动承载架50相对于支撑柱10转动，使得光伏支架100可以根据太阳的照射范围调节承载架50与支撑柱10之间的夹角大小，以完成太阳能光伏板300随着太阳的照射范围调节的改变而调节其与水平面的安装夹角，实现太阳能光伏板300对太阳的照射范围的跟踪。在光伏支架100受到较大的气流冲击时，回转驱动系统30可以通过自身的自锁功能而将承载架50限位固定于支撑柱10，显著降低置于承载架50上的太阳能光伏板300发生晃动的程度，从而提高了置于承载架50上的太阳能光伏板300的安装的稳定性。
进一步地，本方案中的光伏支架100还设有伸缩组件70，在光伏支架100在遇到较大的气流冲击时，通过该伸缩组件70也可以将承载架50限位固定于支撑柱10，避免置于承载架50上的太阳能光伏板300发生晃动，从而进一步地提高了太阳能光伏板300安装的稳定性。并在太阳能光伏板300对太阳的照射范围进行跟踪时，伸缩组件70可以将承载架50未限位固定于支撑柱10，保证光伏支架100的正常工作。
请参考图2，在本申请的一实施例中，回转驱动系统30包括电机31和回转减速器33，电机31设于支撑柱10，回转减速器33连接于电机31，并部分结构插入承载架50内。
可以理解，回转减速器33即为上述的回转驱动系统30内的蜗轮蜗杆机构或者齿轮组机构，将回转减速器33的部分结构插入承载架50内，可以增大两者的接触 面积而提高回转减速器33和承载架50连接的稳定性，保证承载架50稳定的跟随回转减速器33进行转动。
在本申请的一实施例中，光伏支架100还包括夹持件90，夹持件90套设于承载架50的外侧，并使承载架50夹持固定插入承载架50内的回转减速器33。
可以理解，如此设置可以无需设于回转减速器33和承载架50上设置连接结构，避免了因为设有连接结构而影响两者的强度。当然，本申请不限于此，于其他实施例中，回转减速器33和承载架50也可以是通过焊接固定或者螺钉直接连接等，并通过夹持件90的夹持作用以提高两者在连接处的连接强度。
在本申请的一实施例中，夹持件90包括上夹持座91和下夹持座92，下夹持座92可拆卸地连接于上夹持座91，并和上夹持座91相配合套设于承载架50的外侧。
可以理解，如此设置使得夹持件90无需从承载架50的一端进行套设，在所需要安装的位置将上夹持座91和下夹持座92相互对应靠近配合夹持于承载架50即可，从而简化了夹持件90的组装过程。其中，上夹持座91和下夹持座92可以是可拆卸连接，以使其可以拆卸下来进行维修更换。具体地可以为螺钉连接或者卡扣连接。进一步地，还可以通过螺钉穿过夹持件90、承载架50以及回转减速器33，以进一步地提高几者之间的固定效果。
在本申请的一实施例中，伸缩组件70包括缸体71、活塞杆72以及驱动件73；缸体71可转动地连接于支撑柱10和承载架50的其中之一；活塞杆72的一端可移动地设于缸体71内，另一端可转动地连接于支撑柱10和承载架50的其中之另一；驱动件73设于缸体71，驱动件73驱动活塞杆72相对于缸体71移动，并可使活塞杆72限位固定于缸体71。
具体地，伸缩组件70可以为电动推杆，活塞杆72的丝杆和螺母具有自锁功能，在驱动件73通电的状态下，驱动件73可驱动活塞杆72相对于缸体71移动，以适应承载架50相对于支撑柱10的转动。而在驱动件断电的情况下，活塞杆72的丝杆和螺母可以通过自锁功能而使活塞杆72限位固定于缸体71。此时支撑柱10和横梁51通过电动推杆构成刚性连接，实现承载架50的限位固定，从而提高光伏支架100的抗风性能，以保证太阳能光伏安装板的稳定性。由于电动推杆为现有技术，故在此对其的工作原理不作详述。可以理解，采用电动推杆作为伸缩组 件70，不但可以在承载架50受到较大的气流冲击时对承载件进行限位固定，还可以在承载架50相对于支撑柱10转动时提供动力，驱动承载架50相对于支撑柱10转动，提高承载架50的转动动力。当然，本申请不限于此，于其他实施例中，伸缩组件70也可以是包括第一段体、第二段体以及气缸。第一段体连接于支撑柱10，第二段体可移动地设于第一段体，并连接于承载架50，气缸设于第一段体，并可抵接于第二段体，使第二段体限位固定于第一段体。也即，在承载架50需要进行转动时，在第二段体可在第一段体上发生相对移动；在承载架50需要进行限位固定时，气缸的伸缩端靠近第二段体并抵紧于第二段体。
请参考图3，在本申请的一实施例中，承载架50包括横梁51和至少两个斜梁55；横梁51连接于回转驱动系统30，回转驱动系统30驱动横梁51相对于支撑柱10转动；至少两个斜梁55均连接于横梁51，并和横梁51呈夹角设置，每相邻的两个斜梁55形成安置区域55a，太阳能光伏板300安置于安置区域55a内；伸缩组件70远离支撑柱10的一端连接于横梁51。
可以理解，将承载架50由横梁51和斜梁55组装而成可以使得各个零件独立生产制造，从而简化了承载架50的成型的复杂度，提高生产效率。其中，横梁51与斜梁55之间可以是通过螺钉、卡扣或者焊接等方式固定。而横梁51可以是呈一体结构设置，以提高横梁51的强度；当然也可以是呈多段分体拼接结构，以简化每一段体的成型的模具，同时也使得各个段体可以通过螺钉实现可拆卸连接，以便某一段体发生损坏时可以仅针对某一段体进行维修更换。另外，请结合参考图1、图2以及图3，伸缩组件70的活塞杆72可以是转动连接于承载架50的横梁51，回转驱动系统30的回转减速器33的部分结构插入横梁51内，夹持件90的上夹持座91和下夹持座92相配合套设于横梁51的外侧。
请结合参考图1和图3，在本申请的一实施例中，每相邻的两个斜梁55形成两个安置区域55a，两个安置区域55a沿斜梁55的长度方向间隔分布。
可以理解，两个安置区域55a的设置使得承载架50于每两个相邻的斜梁55之间可以安置两个太阳能光伏板300，从而提高了该承载架50对太阳能光伏板300的承载能力。
在本申请的一实施例中，承载架50还包括至少两个斜支撑57，横梁51具有呈相 对设置的上表面和下表面，至少两个斜梁55均设于横梁51上表面，至少两个斜支撑57设于横梁51的下表面，一个斜支撑57和一个斜梁55呈相对设置，并连接于和该斜支撑57对应的斜梁55，每一个斜梁55和与该斜梁55对应的斜支撑57相配合夹持固定于横梁51。
可以理解，斜支撑57的设置可以对承载架50提供支撑作用，从而能够提高斜梁55安装的稳定性，进而提高了置于斜梁55上的太阳能光伏板300的安置的稳定性。而每一个斜梁55和与该斜梁55对应的斜支撑57相配合夹持固定于横梁51的设置，简化了斜梁55和斜支撑57与横梁51的连接结构，将斜梁55和斜支撑57进行固定即可实现三者的固定，从而提高了光伏支架100的组装效率。其中，斜梁55大致呈V形状设置，其中部抵接于横梁51的下表面，两端分别连接于斜梁55的两端。进一步地，为了提高对斜梁55和斜支撑57在横梁51上限位固定效果，横梁51的上表面和下表面设有限位槽，斜梁55和斜支撑57的部分结构均嵌设于该限位槽内，并抵接于限位槽之槽壁。如此进一步地减少斜梁55和斜支撑57在横梁51之长度方向发生移动的可能。
在本申请的一实施例中，斜梁55背离斜支撑57的一侧设有避让空间55b，光伏支架100还包括紧固件，紧固件穿过斜支撑57和斜梁55，并容置于避让空间55b内，紧固件使斜支撑57连接于斜梁55。
可以理解，避让空间55b的设置避免了紧固件凸出斜梁55的表面，导致影响对斜梁55上的太阳能光伏板300的安装，从而保证了太阳能光伏板300紧贴于斜梁55的表面而提高太阳能光伏板300安置的稳定性。其中，紧固件可以为螺钉，而斜梁55的避让空间55b可以贯穿斜梁55的上表面以及相对的两端面，以便于避让空间55b的成型。
本申请还提出一种光伏发电装置1000，该光伏发电装置1000包括光伏支架100和太阳能光伏板300，该光伏支架100的具体结构参照上述实施例，由于本光伏发电装置1000采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有效果，在此不再一一赘述。太阳能光伏板300安置于光伏支架100的承载架50上。
以上仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申 请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
