光伏瓦及具有坡度的光伏屋顶 技术领域
本申请主要涉及光伏领域，具体地涉及一种光伏瓦和具有坡度的光伏屋顶。
背景技术
光伏瓦包括瓦基体和光伏组件，在光伏瓦工作时需要将光伏组件安装到光伏瓦上。将光伏瓦运输到安装地的方法主要是将组装完成的光伏瓦运输到安装地，因瓦基体与光伏组件之间的结构不同以及强度差异较大，在运输过程中需要特殊的包装，这导致成本上升。
此外，为提高施工效率以及降低维修成本，要求瓦基体和光伏组件之间可以快速的安装与拆卸。还有，光伏瓦与光伏组件之间的面积差异，以及不同光伏瓦的光伏组件之间存在缝隙导致视觉效果较差且容易积尘。
所以，如何降低光伏瓦的运输成本和维修成本，提高施工效率，以及提高光伏瓦的美观性和防止积尘是亟待解决的问题。

本发明的较佳实施方式
为让本申请的上述目的、特征和优点能更明显易懂，以下结合附图对本申请的具体实施方式作详细说明。
在下面的描述中阐述了很多具体细节以便于充分理解本申请，但是本申请还可以采用其它不同于在此描述的其它方式来实施，因此本申请不受下面公开的具体实施例的限制。
如本申请和权利要求书中所示，除非上下文明确提示例外情形，“一”、“一个”、“一种”和/或“该”等词并非特指单数，也可包括复数。一般说来，术语“包括”与“包含”仅提示包括已明确标识的步骤和元素，而这些步骤和元素不构成一个排它性的罗列，方法或者设备也可能包含其他的步骤或元素。
此外，需要说明的是，使用“第一”、“第二”等词语来限定零部件，仅仅是为了便于对相应零部件进行区别，如没有另行声明，上述词语并没有特殊含义，因此不能理解为对本申请保护范围的限制。此外，尽管本申请中所使用的术语是从公知公用的术语中选择的，但是本申请说明书中所提及的一些术语可能是申请人按他或她的判断来选择的，其详细含义在本文的描述的相关部分中说明。此外，要求不仅仅通过所使用的实际术语，而是还要通过每个术语所蕴含的意义来理解本申请。
接下来通过具体的实施例对本申请的光伏瓦进行说明。
图1至图3分别是是本申请一实施例的型材的立体示意图、主视示意图和俯视示意图。参考图1至3所示，光伏瓦100包括瓦基体110和光伏组件120。接下来分别对瓦基体110和光伏组件120进行说明。
图4至图6分别是本申请一实施例的瓦基体的立体示意图、主视示意图和俯视示意图。参考图4至图6所示，瓦基体110包括基板111、抬升部112、拼接区域113和第一连接部。
具体地，参考图4和图5所示，瓦基体具有相对的第一侧边111c和第二侧边111d，基板111具有相对的第一表面111a和第二表面111b。在将基板111铺设于屋顶时，第一表面111a朝向屋顶。抬升部112位于第二表面111b，抬升部112沿第一方向D1延伸，其中，第一方向D1从第一侧边111c指向第二侧边111d。抬升部112与第二表面111b的连接方式包括螺钉连接、粘接等方式，也可以是通过一体成型工艺同时制造基板111以及位于其上的抬升部112。
可以理解，本申请中抬升部112的数量不限于图4中所示的2个。其也可以是1个、3个或4个。
参考图4所示，抬升部112相对于第二表面111b的高度沿第一方向D1从第一端112a向第二端112b逐渐升高，结合图5所示，第二端112b与第二侧边111d相邻。结合图5和6所示，在一实施例中，抬升部112具有抬升面112c和固定面。其中，固定面与基板111的第二表面111b连接，所以在图中无法看到固定面，抬升面112c与固定面之间具有预设夹角θ。通过改变预设夹角θ的大小可以调节第二端112b相对于第二表面111b的高度。参考图4和5所示，在本申请中，抬升部112第二端112b相对于第二表面111b的高度h1与瓦基体110沿第一侧边111c处的厚度t1相同。如此，当多个光伏瓦沿第一方向相邻搭接时，可以使得光伏板之间保持齐平。此外，通过抬升部将光伏组件的一端抬升，从而在光伏组件与瓦基体之间形成一个空间有利于光伏组件的散热。
需要说明的是，本申请中的抬升部不限于图4中所示的情形。例如，可以在图4中所示的基础上缩短抬升部112沿第一方向D1的尺寸，或者增加抬升部112沿第二方向D2的尺寸。其中，如图4所示，第二方向D2指的是拼接区域113的延伸方向。
参考图4和5所示，基板111还具有拼接区域113和安装部115。拼接区域113靠近瓦基体110的第二侧边111d，且与抬升部112的第二端112b相邻。安装部115位于基板111的第一表面111a且位于第二侧边111d上。当在屋顶铺设光伏瓦时，瓦基体110可通过拼接区域113与位于沿第一方向D1上端的其他瓦基体进行搭接，通过安装部115可将瓦基体110搭接在用于安装光伏瓦的横梁上。有关瓦基体之间的连接方式以及铺设方法将在后文进行详细描述，在此不再展开。
本申请中的瓦基体的第一连接部用于将瓦基体与光伏组件可拆卸地连接。参考图4和图6所示，第一连接部是位于基板111沿第一方向D1的上端的安装孔114a。需要说明的是，本申请中的第一连接部不限于上述实施例，例如，其也可以是其他可以实现快速拆卸的连接结构，其也可以位于基板的其它位置。后文将对瓦基体与光伏组件的连接方式进行说明，在此不再展开。
参考图4和图6所示，在一些实施例中，瓦基体还包括第一排水槽116。第一排水槽116与瓦基体沿第二方向D2相对的两个侧边中的一侧边响铃，第一排水槽116沿第一方向D1延伸。第一排水槽116靠近抬升部112第一端112a的一端具有开口116a。第一排水槽116可用于收集滴落到光伏板表面的的雨水，然后通过开口116a将雨水排出瓦基体。
继续参考图4至图6所示，瓦基体110还包括位于第二表面111b上的第二排水槽118。第二排水槽118沿第二方向D2延伸，且具有沿第二方向D2朝向瓦基体外侧的开口118a。如图4所示，第二排水槽118的底面具有一定的坡度。具体的，第二排水槽118具有沿第二方向D2与开口118a相对的另一端118b，相比与另一端118b，开口118a更靠近第一表面111a，。从而使得，通过第二排水槽118可加速排除第二表面111b上的水。需要说明的是，本申请中的第二排水槽的形式不限于上述实施例，例如，在图4中，第二排水槽为沿第二方向D2相对分布的两个，在其他一些实施例中，第二排水槽也可以为一个。举例来说，在一些实施例中，当第二排水槽为一个时，相当于把图4中的一个第二排水槽118沿第二方向D2延长，使其与开口118a相对的另一端118b靠近第一排水槽116。
除可以通过上述的第二排水槽加速排除第二表面上的，还可通过在第二表面设置倾斜面的方式加速排除第二表面上的水。
图7所示是本申请一实施例的瓦基体的立体示意图。参考图7所示，第二表面111b具有第一倾斜面111b-1和第二倾斜面111b-2。其中，第一倾斜面111b-1和第二倾斜面111b-2分别与基板111沿第二方向D2相对的两个侧边相邻，第一倾斜面111b-1沿第二方向D2靠近抬升部112的一侧边被抬起，第二倾斜面111b-2沿第二方向D2靠近抬升部112的一侧边被抬起，从而可以通过第一倾斜面111b-1和第二倾斜面111b-2加速排除第二表面111b上的水。
参考图4和5所示，在一些实施例中，瓦基体110的第一侧边111c具有若干线缆避让槽119。线缆避让槽119可用于容纳线缆，如此可避免线缆对瓦基体110之间搭接的干涉，从而提高瓦基体110之间搭接的稳定性。图8至10是本申请一实施例的光伏组件的立体示意图，主视示意图和俯视示意图。
参考图8至10所示，光伏组件120包括光伏板121和第二连接部。参考图2所示，光伏板121设置在抬升部112上，且与瓦基体110间通过第一连接部和第二连接部间的配合可拆卸连接。本申请中的第一连接部和第二连接部能够实现瓦基体和光伏组件之间的快速拆卸，本申请不对第一连接部和第二连接部的具体结构做限制，其包括所有能够实现瓦基体和光伏组件之间快速拆卸的连接结构。为便于理解本申请中的连接部件，这里给出两个非限制性的实施例。
实施例一
参考图4和图8所示，在该实施例中，第一连接部包括设置于拼接区域113上的安装孔114a及与安装孔114a相对的卡接卡槽114b。在该实施例中安装孔114a实施为螺栓孔。如图4所示，安装孔114a位于拼接区域113沿第二方向D2的中部且靠近抬升部112的第二端112b。卡接卡槽114b是位于基板111靠近第一侧边111c的一端的凹槽。
参考图8所示，第二连接部包括相对的卡接卡件122a和连接件122b。连接件122b位于光伏板121被抬高的一端，连接件122b与光伏板121之间为可拆卸连接，连接件122b具有与安装孔114a相对应的通孔。
瓦基体110与光伏组件120的安装方式如下。首先，结合图1、图4和图8所示，将光伏板121的两个卡接卡件122a分别卡接在基板111上对应的卡接卡槽114b内；然后，将连接件122b的通孔与安装孔114a对齐；之后，使用螺栓130穿过连接件122b的通孔与安装孔114a，从而将连接件122b与安装孔114a连接在一起。需要说明的是，上述实施例仅是示例性的。例如，安装孔114a可以是没有螺纹的导向孔，在导向孔的定位下，可通过自攻螺钉穿过连接件122b的通孔将光伏组件与瓦基体连接。
实施例二
图11是本申请一实施例的瓦基体的立体示意图，图12是本申请一实施例的光伏组件的立体示意图。参考图12所示，在实施例二中，第一连接部实施为位于瓦基体110第二表面111b上的四个安装卡孔114c。参考图13所示，第二连接部实施为位于光伏板121背向太阳一面的四个卡扣122c。当光伏组件与瓦基体 连接时，通过将四个卡扣122c分别与对应的安装卡孔114c卡接，如此可实现光伏组件与瓦基体的快速安装和拆卸。需要说明的是，图11和12只是示出了部分瓦基体和光伏组件的结构，其他细节可以参考前文有关的说明，在此不再赘述。
在对光伏瓦进行包装以及将光伏瓦运输到安装现场时，由于光伏组件和瓦基体自身结构以及强度不同，如果将光伏组件和瓦基体组装后再进行包装，则需要设计特殊的包装材料。此外，组装后的光伏瓦对物流的要求较高。从而提高了光伏瓦的包装成本和运输成本。上述实施例中，通过第一连接部件和第二连接部件可实现瓦基体与光伏组件之间的快速拆卸。如此，可以将瓦基体和光伏组件分别进行包装和运输，降低了包装成本和运输成本。当需要更换光伏组件时，还可以快速地对光伏组件进行拆卸和安装。此外，本申请通过位于光伏板背向太阳一面的第二连接部将将光伏板与瓦基体进行连接，与在光伏板侧边设置连接部件相比，本申请中的光伏板的侧边不存在高出光伏板朝向太阳一面的边框，因此有利于雨水将沉积在光伏板朝向太阳一面的灰尘冲走。
如图1所示，在一些实施例中，瓦基体110的第一侧边111c具有连接件避让槽117。连接件避让槽117的底面朝向光伏瓦100安装时屋顶所在的方向。图13是本申请一实施例的光伏屋顶的立体示意图，图14是图13中的光伏屋顶的主视示意图。结合图13和14所示，当两个相邻的光伏瓦100和200搭接时，光伏瓦200的连接件避让槽117用于容纳光伏瓦100的连接件。如此，有利于提高相邻光伏瓦之间搭接的稳定性。
参考图8所示，在一实施例中，光伏组件120还包括接线盒123。接线盒123位于光伏组件120背向太阳的一面。通过接线盒123可将光伏组件120与外部部件进行连接。
为便于理解本申请中光伏瓦之间的连接方式，这里给出一个将光伏瓦安装在屋顶的实施例。
参考图14所示，屋顶具有三个沿第一方向D1间隔分布的横梁140。光伏瓦100、光伏瓦200和光伏瓦300沿第一方向D1依次搭接在横梁140上。具体为，光伏瓦200的下端搭接在光伏瓦100的拼接区域113上，光伏瓦300的下端搭接在光伏瓦200的拼接区域113上。光伏瓦100、光伏瓦200和光伏瓦300 分别通过自身的安装部115搭接在对应的横梁140上。其中，如图5所示，安装部115为位于基板111的第一表面111a上且沿第二方向延伸的凸起。在光伏瓦自身重力的作用下，通过安装部115可将光伏瓦搭接在横梁140上，从而防止光伏瓦沿第一方向D1向下移动。可以理解，安装部的结构和位置不限于上述实施例，可以根据光伏瓦所安装在的屋顶的具体结构来设置安装部的结构和位置。
如前文所述，参考图4和图5所示，抬升部112第二端112b相对于第二表面111b的高度h1与瓦基体靠近第一侧边111c的一端的厚度t1相同。结合图13和14所示，位于瓦基体110上的光伏板121的一端被抬升部112的第二端112b抬高，从而使得沿第一方向D1相邻的瓦基体上的光伏板121处于同一平面。
参考图14所示，在一些实施例中，光伏瓦100、光伏瓦200和光伏瓦300上的光伏板121沿第一方向D1相对分布的侧边彼此相接触，从而使得相邻的光伏板121无间隙地拼接在一起。具有防止灰尘通过光伏板间的间隙进入到光伏板下方空间的优点，有效地避免了积尘。且上述实施例中的光伏瓦通过抬升部将光伏组件的一端抬高，从而使得相邻光伏瓦的光伏板齐平，提高了光伏瓦的美观性，同时具有防止积尘的效果。
在本申请一实施例中，一个光伏组件覆盖的瓦基体的数量等于或大于2。可以理解，可以根据需求决定光伏组件所覆盖的瓦基体的数量。举例来说，参考图15和16所示的本申请两实施例的光伏屋顶的立体示意图。与图13中的实施例不同的是，在图13中，一个光伏组件覆盖一个瓦基体，在图15的实施例中，光伏组件400大致为方形，覆盖了四个瓦基体。本申请不对光伏组件的形状做限制，例如，在图16的实施例中光伏组件500大致为长方形，覆盖四个瓦基体110。
本申请另一方面还提出一种具有坡度的光伏屋顶。光伏屋顶包括若干个如前文所述的光伏瓦。铺设于上述光伏屋顶的光伏瓦上的光伏组件的一端被抬高，从而使得相邻光伏瓦的光伏板齐平，提高了光伏瓦的美观性，同时具有防止积尘的效果。
上文已对基本概念做了描述，显然，对于本领域技术人员来说，上述申请披露仅仅作为示例，而并不构成对本申请的限定。虽然此处并没有明确说明， 本领域技术人员可能会对本申请进行各种修改、改进和修正。该类修改、改进和修正在本申请中被建议，所以该类修改、改进、修正仍属于本申请示范实施例的精神和范围。
同时，本申请使用了特定词语来描述本申请的实施例。如“一个实施例”、“一实施例”、和/或“一些实施例”意指与本申请至少一个实施例相关的某一特征、结构或特点。因此，应强调并注意的是，本说明书中在不同位置两次或多次提及的“一实施例”或“一个实施例”或“一替代性实施例”并不一定是指同一实施例。此外，本申请的一个或多个实施例中的某些特征、结构或特点可以进行适当的组合。
一些实施例中使用了描述成分、属性数量的数字，应当理解的是，此类用于实施例描述的数字，在一些示例中使用了修饰词“大约”、“近似”或“大体上”来修饰。除非另外说明，“大约”、“近似”或“大体上”表明所述数字允许有±20％的变化。相应地，在一些实施例中，说明书和权利要求中使用的数值参数均为近似值，该近似值根据个别实施例所需特点可以发生改变。在一些实施例中，数值参数应考虑规定的有效数位并采用一般位数保留的方法。尽管本申请一些实施例中用于确认其范围广度的数值域和参数为近似值，在具体实施例中，此类数值的设定在可行范围内尽可能精确。
