具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能解释为对本发明的限制。
如图1至图3所示，本发明实施例提供了一种薄膜光伏组件的背挂式安装总成，用于固定光伏组件，该光伏组件包括依次叠置的玻璃背板1、薄膜太阳能电池芯片和玻璃顶板。图1仅示例性地示出了玻璃背板1，实际上，薄膜太阳能电池芯片和玻璃顶板依次叠置在玻璃背板1上，形成双玻组件。本领域技术人员可以理解的是，本实施例提供的安装总成并不限于使用在双玻组件上，其目的是避免对背板的直接夹持，因此，该安装总成的适用范围较大，并不限于本实施例中提及的双玻组件。本实施例中的双玻组件包含钢化玻璃的前板，带防反射涂层，长宽尺寸为1190*789.5mm、厚度为4mm。玻璃背板1为浮法玻璃，长宽尺寸为1190*789.5mm、厚度尺寸为3mm，选用浮法玻璃可以减少光伏组件的衰减，提高光电转化效率，
该安装总成包括背挂钩板2和横梁4，其中，背挂钩板2的断面为F形，与光伏组件连接，具体为背挂钩板2与玻璃背板1固定连接，横梁4用于与屋顶固定连接，且与上述背挂钩板2钩接固定。
优选地，背挂钩板2包括横板21、第一L形板22和第二L形板23，横板21与玻璃背板1固定连接，第一L形板22的第一端和第二L形板23 的第一端均固定在横板21上；第一L形板22的第二端和第二L形板23的第二端均形成向同一方向弯折、且高度不同的挂钩状。背挂钩板2形成断面类似于F形的结构。
横梁4包括底板41、第三L形板42和第四L形板43，底板41用于与屋顶固定连接，第三L形板42的第一端和第四L形板43的第一端均固定在底板41上；第三L形板42的第二端和第四L形板43的第二端均形成向同一方向弯折、且高度不同的挂钩状，且第三L形板42与所述第一L形板22钩接，第四L形板43与第二L形板23钩接。横梁4形成断面类似于F形的结构。
本发明实施例提供的薄膜光伏组件的背挂式安装总成，设置有断面类似为F形的背挂钩板2，其一端与玻璃背板1固定连接，另一端与横梁4钩接固定，再通过横梁4与屋顶连接，从而实现了光伏组件在屋顶的安装。并且在设置时，安装总成在出厂时双玻组件与背挂钩板2是一个整体，即背挂钩板2与双玻组件在工厂内进行组装，背挂钩板2的位置及尺寸都可以严格控制。因此，背挂钩板2安装在横梁4上时，整个安装总成的整体荷载及平整度将比较高，保证了整个双玻组件的稳定性，而现有技术中采用的夹具安装时，夹具相对于组件是可以移动的，在安装过程中很难保证夹具位置的准确性，使得整个组件受力不均匀，容易导致双玻组件破碎，尤其在遇到恶劣天气时，更容易出现损坏，造成严重损失。另外采用上述的背挂钩板2与横梁4结构简单，安装较为便利。
优选的是，背挂钩板2与玻璃背板1之间通过结构胶3固定连接。可以理解的是，背挂钩板2也可以通过铆接、螺接或其他方式与玻璃背板1固定连接。在一个具体的实施方案中，采用结构胶3将背挂钩板2与玻璃背板1固定连接，在采用结构胶3时，该结构胶3具有强度高，能承受较大荷载的优点，并且耐老化、耐疲劳、耐腐蚀，在结构胶3的预期寿命内性能稳定，并且能够承受强力的结构件粘接，从而使得背挂钩板2与玻璃背板1之间的连接比较牢固。在具体设置结构胶3时，结构胶3的面积大于背挂钩板2的单面，即结构胶3与玻璃背板1的粘接面积大于横板21的面积，在采用这种设置方式时，不仅保证了结构胶3在粘贴时的牢固性，而且彻底隔绝双玻组件与金属(背挂钩板2)接触，从而能够有效预防组 件的PID效应，而现有技术中采用的夹具安装设计夹具过多，很难避免组件与金属接触。
在采用背挂钩板2时，该背挂钩板2支撑在玻璃背板1背离玻璃顶板的表面上，此时，背挂钩板2不仅仅作为一个连接件，同时还作为玻璃背板1的一个支撑件，以保证双玻组件的机械强度。如图3及图4所示，背挂钩板2具有一定的长度与宽度，从而可以给玻璃背板1很好的支撑强度，改善在玻璃背板1尺寸过大时出现中间凹陷的情况。在具体设置时，该背挂钩板2的长度方向可以与玻璃背板1的单边平行或者垂直，当然也可以采用其他的呈一定角度的方式设置，从而提高对玻璃背板1的支撑效果。而现有技术中的夹具安装在双玻组件边缘，造成整个双玻组件的中间部位支撑效果较差，组件中部会出现微微下凹现象，使得整个装置稳定性较差。
进一步地，本实施例提供的安装总成还包括限位螺栓5，该限位螺栓5穿过第一L形板22后抵顶在第三L形板42上；和/或，该限位螺栓5穿过第四L形板43后抵顶在第二L形板23上，从而限制背挂钩板2与横梁4的相对移动。
进一步地，本实施例提供的安装总成还包括第一固定螺栓6，第一固定螺栓6穿过底板41后与第一L形板22和/或第二L形板23固定连接。具体的，既可以第一固定螺栓6与第一L形板22固定连接，也可以第一固定螺栓6与第二L形板23连接，或者第一固定螺栓6的个数为两个，且分别与第一L形板22及第二L形板23连接。
进一步地，本实施例提供的安装总成还包括斜梁8，上述横梁4的底板41固定在斜梁8上，斜梁8用于与屋顶固定连接。该安装总成还可以包括第二固定螺栓7，第二固定螺栓7穿过底板41后与斜梁8固定连接。通过设置第一固定螺栓6和第二固定螺栓7实现横梁4与背挂钩板2、横梁4与斜梁8的稳定连接。
如图4所示，在上述实施例的基础上，本发明实施例提供的薄膜光伏组件的背挂式安装总成还包括立柱9，立柱9的顶端与斜梁8远离底板41的一侧固定连接，立柱9的底端与屋顶固定连接。立柱9与斜梁8之间可以通过支架固定连接，通过设置立柱9将光伏组件撑起一定的高度，并通过斜梁8的设置使光伏组件倾斜一定的角度，从而更好地吸收光照，提高 了电能的转化效率。
背挂钩板2的数量可以根据光伏组件的大小来设定，本实施例中，背挂钩板2的数量是两个，两个背挂钩板2相互垂直或相互平行，以提高光伏组件的安装强度。背挂钩板2的材质可以是铝合金，从而使安装结构轻量化。在采用铝合金时，该铝合金具有抗腐蚀性，放置在空气中时，背挂钩板2的表面可以形成致密的氧化铝保护层，从而防止背挂钩板2的进一步氧化，提高了背挂钩板2的化学稳定性。而且，铝合金在低温环境中的强度增强，从而可以使得背挂钩板2可以满足支撑强度的要求，尤其是在寒冷天气时，提高了在支撑时的可靠性。此外，该背挂钩板2在采用铝合金材质时，能够更好的传导光伏系统中各种原因所产生的弱电流，提高整个安装总成的安全性。
以上依据图式所示的实施例详细说明了本发明的构造、特征及作用效果，以上所述仅为本发明的较佳实施例，但本发明不以图面所示限定实施范围，凡是依照本发明的构想所作的改变，或修改为等同变化的等效实施例，仍未超出说明书与图示所涵盖的精神时，均应在本发明的保护范围内。
