在本实施例的描述中，术语“上”、“下”、“左”、“右”等方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述和简化操作，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本实用新型的限制。此外，术语“第一”、“第二”仅仅用于在描述上加以区分，并没有特殊的含义。
如图1所示，本实施例提供了一种光伏发电装置，用于将太阳光能转化为电能。具体而言，光伏发电装置包括光伏跟踪支架1000以及光伏组件2000，其中，光伏组件2000为光伏发电装置中的核心部件，能够将太阳光能转化为电能，光伏跟踪支架1000用于支撑并固定光伏组件2000，并且该光伏跟踪支架1000能够适用于平地和水面打桩电站，具有较高的通用性。
结合图1对光伏跟踪支架1000的具体结构进行说明，如图1所示，光伏跟踪支架1000包括光伏主梁100以及安装檩条200，其中，安装檩条200设置在光伏主梁100上，安装檩条200用于固定光伏组件2000，光伏主梁100能够带动安装檩条200和光伏组件2000随着太阳的移动而转动，以保证太阳光尽可能地垂直照射在光伏组件2000上，保证光伏组件2000的发电效率。
在本实施例中，如图2所示，安装檩条200可以包括檩条主体210以及檩条加强件220，檩条主体210用于固定光伏组件2000，檩条加强件220设置在檩条主体210上。通过设置檩条加强件220，增强了整个安装檩条200的结构强度。
具体而言，如图2所示，檩条主体210可以呈几字形，几字形的檩条主体210可以包括底板、两个侧板和两个横板，檩条主体210的两个侧板设置 在檩条主体210的底板的相对的两侧，檩条主体210的两个横板一一对应的设置在檩条主体210的两个侧板上，并横向外伸，檩条主体210的外伸的两个横板用于固定光伏组件2000，檩条加强件220呈U形，U形的檩条加强件220可以包括底板和两个侧板，檩条加强件220的两个侧板设置在檩条加强件220的底板的相对的两侧，檩条加强件220设置在几字形的檩条主体210的内部，檩条加强件220的底板与檩条主体210的底板相固定，檩条加强件220的两个侧板一一对应的与檩条主体210的两个侧板贴合。该设置方式进一步增强了安装檩条200的结构强度。
目前市场上的光伏组件2000通常为双面组件，双面组件的背面也可吸收太阳光进行发电。现有技术中，通常将安装檩条200直接与光伏主梁100相固定，使得光伏主梁100与双面组件的背面距离较近，导致光伏主梁100会对双面组件的背面造成一定的遮挡，从而降低了双面组件的发电量。
为了解决上述问题，如图1所示，本实施例提供的光伏跟踪支架1000可以还包括连接组件300，安装檩条200通过连接组件300与主梁1相固定。
具体而言，连接组件300可以分别与安装檩条200和主梁1固定，用于将安装檩条200固定在光伏主梁100上，这与现有技术相比，安装檩条200不是直接与光伏主梁100相固定，而是通过连接组件300与光伏主梁100相固定，通过设置连接组件300，增加了安装檩条200与光伏主梁100之间，以及双面组件与光伏主梁100之间在高度方向上的间距，从而减少了光伏主梁100对双面组件的背面的遮挡，保证了双面组件的发电量。此外，通过设置连接组件300，也提高了安装檩条200与光伏主梁100之间安装的稳定性。
结合图1和图3对连接组件300的具体结构进行说明，如图1和图3所示，连接组件300可以套设在光伏主梁100上，保证连接组件300与光伏主梁100连接配合的更加稳固。具体而言，连接组件300可以包括两组U型连接板310，两组U型连接板310以光伏主梁100为对称轴对称设置，即， 两组U型连接板310以光伏主梁100为对称轴对称套设在光伏主梁100上。通过对称设置的两组U型连接板310，更加便于实现连接组件300与光伏主梁100之间的安装。在安装连接组件300时，只需要将两组U型连接板310对拼套设在光伏主梁100上即可。
此外，如图1～图3所示，连接组件300可以还包括固定件320，固定件320依次穿过檩条加强件220、檩条主体210、其中一组U型连接板310以及另一组U型连接板310，从而将安装檩条200与两组U型连接板310相固定，进而将安装檩条200与光伏主梁100相固定。
具体而言，固定件320可以包括六角螺栓，六角螺栓的头部位于檩条加强件220的内部，并且檩条加强件220的两个侧板的侧壁能够限制六角螺栓的头部转动，从而防止六角螺栓在固定位置发生松动，提高连接的稳定性。需要说明的是，檩条加强件220的两个侧板之间的间距需要大于六角螺栓头部内切圆的直径，并且两个侧板之间的间距需要小于六角螺栓头部外切圆的直径，该设置方式能够保证六角螺栓沿着头部内切圆的直径的两侧放置在檩条加强件220的两个侧板之间，也能够防止六角螺栓在檩条加强件220的两个侧板之间发生转动。
现有的光伏主梁上的主梁通常为方管或者圆管，当主梁采用方管时，主梁虽然具有较好的抗弯强度，但是抗扭强度差，当主梁采用圆管时，主梁虽然具有较好的抗扭强度，但是抗弯强度差，使得主梁无法兼具良好的抗弯强度和抗扭强度。
为了解决上述问题，如图2和图4所示，本实施例提供的光伏主梁100包括主梁1，主梁1的横截面呈方形，且方形的边角处呈圆弧面111，方形的边角处通过圆弧面111光滑过渡，并且圆弧面111的弧长为方形边长的1/6～1/4。该设置方式使得主梁1横截面所呈的方形的边角处具有较大的圆角，相对于同质量的其它形式的主梁，不仅提高了主梁1的抗弯属性，也提 高了主梁1的抗扭属性，增强了主梁1的结构强度。需要说明的是，在本实施例中，固定件320依次穿过檩条加强件220、檩条主体210、其中一组U型连接板310以及另一组U型连接板310，从而将安装檩条200与两组U型连接板310相固定，进而将安装檩条200与主梁1相固定。
可选地，如图4所示，主梁1可以呈管状，并且主梁1的壁厚可以为2.5mm～6mm。该设置方式在保证主梁1抗弯轻度和抗扭强度的基础上，进一步节省主梁1的使用材料，降低成本。
进一步地，如图4所示，主梁1的横截面所呈的方形可以为正方形，正方形的各个边角处可以均采用圆弧面111光滑过渡，保证主梁1各个部位的强度属性均匀。需要说明的是，主梁1的横截面所呈的正方形的边长可以为100mm～200mm，圆弧面111的半径可以为20mm～50mm，圆弧面111的弧度可以为1/2π，该尺寸范围能够保证主梁1对光伏组件2000的有效承载。
由于主梁1的长度较长，一般需要多个主梁1沿预设方向拼装起来。在现有技术中，各个主梁1之间通常通过抱箍进行拼接固定，由于抱箍需要套设固定在主梁1的外部，导致抱箍对安装檩条200在主梁1上的连接造成干涉，安装檩条200需要避让主梁1上安装有抱箍的部位。
为了解决上述问题，如图2所示，本实施例提供的主梁1的数量可以为多个，多个主梁1沿预设方向套设拼装连接。该设置方式能够避免主梁1的外周上存在突出部件，使得安装檩条200在主梁1上的连接位无需避让主梁1的拼装位置，使得安装檩条200在主梁1上的连接更加灵活。此外，主梁1之间通过套设的方式拼装固定，由于拼装位置需要进行嵌套，使得连接部位结构更加稳固。
结合图5对主梁1的具体结构进行说明，如图5所示，主梁1可以包括依次相连接的穿设部11、主体部12以及套设部13，主梁1的穿设部11穿设固定在相邻主梁1的套设部13中，从而实现多个主梁1之间的套设拼装。
为了保证穿设部11能够穿设在套设部13中，穿设部11的尺寸需要小于套设部13的尺寸。此外，穿设部11和套设部13的长度可以根据主梁1之间传递的扭矩进行确定，只要能够保证穿设部11和套设部13之间的稳固固定即可。
此外，如图2和图5所示，光伏主梁100可以还包括锁紧件2，穿设部11上开设有沿其轴向间隔排布的多个第一安装孔112，套设部13上对应开设有多个第二安装孔131，锁紧件2依次穿过第二安装孔131和第一安装孔112，从而将主梁1的穿设部11与相邻主梁1的套设部13相固定。具体而言，锁紧件2可以为螺栓，螺栓具有连接可靠、成本低的优点。
也就是说，穿设部11上开设有多个第一安装孔112，多个第一安装孔112沿穿设部11的轴向间隔排布，套设部13上开设有多个第二安装孔131，多个第二安装孔131沿套设部13的轴向间隔排布，第二安装孔131的数量、第一安装孔112的数量和锁紧件2的数量相同，多个第二安装孔131与多个第一安装孔112一一对应设置，多个锁紧件2一一对应的穿过第二安装孔131和第一安装孔112，从而将主梁1的穿设部11与相邻主梁1的套设部13相固定。
显然，本实用新型的上述实施例仅仅是为了清楚说明本实用新型所作的举例，而并非是对本实用新型的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型权利要求的保护范围之内。
