Description

一种双玻光伏组件护角及其安装方法 技术领域
本发明涉及一种光伏组件的护角，尤其涉及一种双玻光伏组件护角，同时，本发明还涉及一种双玻光伏组件护角的安装方法，属于太阳能光伏组件技术领域。
背景技术
双玻光伏组件顾名思义盖板和背板都采用玻璃制作，其可直接作为建材直接使用，抗冲击等安全性能也高于普通光伏组件，是常见的光伏组件类型之一。双玻光伏组件的结构一般包括依次层叠的盖板玻璃、封装材料、电池串、封装材料、背板玻璃，上述各层材料经层压及其他工序后形成双玻光伏组件。由于双玻组件没有边框，而且使用的是钢化玻璃，在搬运的过程中，组件的角部如果受到撞击，很容易发生破裂。为了解决这个问题，现有技术中一般在组件层压完成后在组件上安装护角，这样需要增加一道额外的工序；同时，护角一般采用硅胶安装，硅胶太少影响护角牢固度，硅胶太多会溢到护角和组件表面，增加清洗难度；此外，在组件层压完成后到护角安装前同样有容易破裂的问题。
发明内容
本发明针对现有技术中双玻光伏组件容易受到撞击而损坏、破裂；以及现有技术中护角的安装工序比较繁琐的技术问题，提供一种双玻光伏组件的层压方法及其专用护角。
为此，本发明采用如下技术方案：
一种双玻光伏组件护角，包括用于包覆在组件角部两条边上的两个侧壁，其特征在于：沿两个侧壁的顶边延伸出一个平的顶壁，两个侧壁的底边形成开放的自由端，在顶壁上、沿所述顶边设置有溢胶槽，溢胶槽的外侧设置有阻胶棱，在两个侧壁上分别设置有排气孔。通过两个侧壁和一个顶壁，对组件的角部形成充分的保护，防止组件因碰撞等原因造成的损伤；同时，具有一个开放的自由端，使得本发明可以在组件层压的过程中即实现与组件的固定安装，简化了工序，降低了生产成本。
进一步地，所述两个侧壁之间的夹角为85-90度。侧壁之间小于等于85-90度的夹角可对组件的角度形成一定的夹持力，方便护角的安装和初步固定。
进一步地，在两个侧壁上分别设置有加强筋。增强侧壁的机械强度和对组件角部的保护性能。
进一步地，所述顶壁的外侧边缘呈向内凹的弧形。在保持有效的保护效果的基础上，节省护角的用料，降低成本。
因此，本发明双玻光伏组件护角，可有效地保护光伏组件，防止其因撞击而 破坏；同时，方便安装。
本发明的另一方面，还提供一种双玻光伏组件护角的安装方法，包括如下步骤：
S1：将双玻组件的各层按次序叠放好；
S2：在组件的四个角上放置好上述护角，并将护角初步固定在组件上；
S3：各层在常规工艺下层压，层压完成，护角被最终固定在组件的四个角上；
S4：后期清理。
本安装方法，护角随组件一起层压，在组件层压的同时完成护角的安装，提升了护角粘接的牢固度，减轻护角安装难度，简化了安装工序，同时，可有效地保护组件，降低组件的报废率。
附图说明
图1为本发明实施例1的结构示意图；
图2为本发明实施例1安装在组件上的结构示意图；
图中，1为侧壁，11为顶边、12为底边，2为顶壁，3为溢胶槽，4为阻胶棱，5为排气孔，6为加强筋，100为双玻光伏组件。
具体实施方式
为了使本技术领域的人员更好的理解本发明方案，下面将结合附图对本发明的技术方案进行清楚、完整的描述，本发明中与现有技术相同的部分将参考现有技术。
实施例1：
如图1-2所示，本发明的双玻光伏组件护角，包括用于包覆在组件角部两条边上的两个侧壁1，沿两个侧壁的顶边11延伸出一个平的顶壁2，顶壁2的外侧边缘呈向内凹的弧形；两个侧壁的底边12形成开放的自由端，在顶壁2上、沿所述顶边设置有溢胶槽3，溢胶槽3的外侧设置有阻胶棱4，在两个侧壁上分别设置有排气孔5。两个侧壁1之间的夹角为85-90度，在本实施例中，选择89度，小于90度的夹角可对组件角度形成一定的夹持，在两个侧壁1上分别设置有加强筋6。
实施例2：
本发明的另一方面，提供一种双玻光伏组件护角的安装方法，包括如下步骤：
S1：将双玻组件的各层按次序叠放好，依次为盖板玻璃、封装材料、电池串、封装材料、背板玻璃；
S2：在组件的四个角上放置好上述护角，护角的顶壁位于组件的背板玻璃的上方，用胶带将护角初步固定在组件上，固定的胶带避开护角上的排气孔5；
S3：各层在常规工艺下层压，层压时，封装材料层，如EVA层，熔化，并 流动至护角和玻璃的缝隙之间并填满溢胶槽3，冷却后护角即粘在组件的四个角上，即：组件的层压过程完成，护角即被最终固定在组件的四个角上；
S4：后期清理；在后续清理时只需将叠层时粘贴的固定胶带去掉，将从溢胶孔溢出的胶清掉即可，护角即牢固的安装在组件四角上。
显然，所描述的实施例仅仅是本发明的部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
