本申请涉及光伏支架技术领域，尤其涉及一种柔性光伏支架及光伏阵列。
现有光伏阵列中的柔性光伏支架结构体系一般采用双索支撑（无附加索和空间桁架）和三索支撑，通过对与光伏组件直接接触的双索施加预应力来抵抗结构自重以及风雪工况下的作用力。由于采用了柔性的索结构进行支撑，出现了结构刚度小，跨中挠度大，抗风能力弱，极易产生大幅振动的问题。
基于此，有必要提供一种柔性光伏支架及光伏阵列，旨在解决现有光伏阵列中的柔性光伏支架的刚度过小的技术问题。

为了更清楚地说明本申请实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
其中：
图1为一个实施例中柔性光伏支架的示意图；
图2为图1所示柔性光伏支架中连接索、加固桁架和索桁机构的位置示意图；
图3为图1所示柔性光伏支架中连接索、高位索、低位索、加固桁架与安装架的位置示意图。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例提供一种光伏阵列，其实质上为一种光电转化设备，可以安装于公司、学校、工厂或野外等各种空旷场合环境中，实现将太阳能转化成电能，以提高和改善人们可再生能源的应用。
请一并结合图1至图3，现对本申请提供的光伏阵列进行说明。该光伏阵列包括柔性光伏支架10、安装架20和光伏组件。进一步地，该柔性光伏支架10包括第一支撑组件11、索桁机构组、第二支撑组件13和连接索14及加固桁架15。其中，第一支撑组件11的数量为多个且沿第一方向间隔设置。索桁机构组包括多个沿第一方向延伸并依次设于各第一支撑组件11上的索桁机构12。各索桁机构12沿第二方向间隔设置，第二方向垂直于第一方向，索桁机构12包括高位索121和低位索122。高位索121和低位索122均沿第一方向延伸并与第一支撑组件11连接。第二支撑组件13沿第二方向位于索桁机构组两侧。连接索14的数量为多个，各连接索14沿第二方向延伸并与第二支撑组件13连接，各连接索14至少一一对应连接于各索桁机构12。加固桁架15沿第三方向设置，并连接于高位索121和连接索14之间，第三方向垂直于第一方向和第二方向所在平面。第一方向平行于图1中箭头X所指方向，第二方向平行于图1中箭头Y所指方向，第三方向平行于图1中箭头Z所指方向。
综上，实施本申请实施例，将具有如下有益效果：上述方案的柔性光伏支架10应用装备于光伏阵列中，除了使光伏阵列具备极佳的光电转化效能之外，其自身还具有较高刚度的效果。具体而言，该柔性光伏支架10包括多个沿第一方向延伸并依次设于各第一支撑组件11上的索桁机构12和多个沿第二方向延伸并与第二支撑组件13连接的连接索14，各连接索14至少一一对应连接于各索桁机构12。如此使得索桁机构12能够在垂直于其延伸方向上得到连接索14的支撑，同时，柔性光伏支架10还包括沿第三方向设置并连接于高位索121和连接索14之间的加固桁架15。如此使得连接索14能够通过加固桁架15对高位索121提供支撑，从而提高了索桁机构12的刚度和抗风能力，避免出现大幅振动和翻转，进而提高了柔性光伏支架10整体的刚度和稳定性。
在一个实施例中，如图2和图3所示，安装架20分别与高位索121和低位索122连接，以使安装架20倾斜，光伏组件设于安装架20。如此使得光伏组件能够倾斜设置以面向太阳。
在一个实施例中，请继续参阅图2和图3，安装架20通过高位索121和加固桁架15的连接处与高位索121连接。如此使得连接索14提供的支撑力能够通过加固桁架15作用于安装架20，进一步保证安装架20倾斜角度的稳定。
进一步地，各连接索14至少一一对应连接于各索桁机构12，具体指，各连接索14一一对应连接于各索桁机构12，即每个连接索14连接一个索桁机构12。或者，每个连接索14连接两个以上索桁机构12。如图1和图2所示，本实施例中，连接索14将各索桁机构12连为一体，即连接索14将各索桁机构12串联。如此使得连接索14能够沿索桁机构组的纵向将各索桁机构12连为一体，利用连接索14的抗拉性能能够提高索桁机构组的整体稳定性。
进一步地，连接索14可通过与高位索121、低位索122和加固桁架15中的至少一者连接，进而实现对索桁机构12整体支撑。如图2和图3所示，本实施例中，连接索14分别与低位索122和加固桁架15的一端连接，加固桁架15的另一端与高位索121连接。由于高位索121高于低位索122，上述设置能够保证连接索14呈水平设置且靠近低位索122以及加固桁架15与高位索121的连接处，以提高高位索121、低位索122和加固桁架15的整体刚度，防止索桁机构12发生扭转，进而提高索桁机构12的稳定性。
在一个实施例中，如图3所示，加固桁架15呈杆状，加固桁架15沿第三方向上的尺寸等于高位索121和低位索122的高度差。如此能够保证高位索121、低位索122和连接索14之间连接的稳定性，避免连接后高位索121、低位索122和连接索14发生弯折。
进一步地，如图3所示，安装架20、加固桁架15和连接索14之间能够形成稳定的三角形，从而能够进一步地提高光伏组件倾斜的稳定性。进一步地，安装架20与加固桁架15和低位索122以及安装架20与光伏组件之间可为可拆连接，以方便维修和更换。
在一个实施例中，如图1所示，连接索14的端部具有自对应的第二支撑组件13向外延伸的延伸段141，延伸段141与固定柱连接。如此就能够进一步提高连接索14的稳定性，本实施例中，固定柱沿第二方向设于第二支撑组件13的外侧，可与第二支撑组件13一同设于地面或基台等固定结构上。同时上述设置还能够使连接索14能够提供给第二支撑组件13下压力，以提高其与地面或基台等固定结构连接的稳定性。本实施例中，固定柱可嵌入地面或基台等固定结构。连接索14为柔性连接构件或刚性连接构件，其中，柔性连接构件为钢绞线。本实施例中，连接索14为钢绞线，并预先施加预应力与第二支撑组件13和索桁机构12连接。固定柱可采取包括但不限于H型钢、空心钢管、钢管混凝土等不同的截面形式和材料类型的结构。本实施例中，固定柱为空心钢管。高位索121和低位索122可为钢绞线。
在一个实施例中，第一支撑组件11包括多个沿第二方向间隔设置的第一立柱111和将各第一立柱111连为一体的横梁112，高位索121和低位索122均与横梁112连接。如此能够提高第一支撑组件11整体的稳定性，进而提升柔性光伏支架10整体的稳定性。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所揭露的仅为本申请较佳实施例而已，当然不能以此来限定本申请之权利范围，因此依本申请权利要求所作的等同变化，仍属本申请所涵盖的范围。
