Description

一种密封结构及具有该密封结构的发电系统 技术领域
本申请涉及光伏发电技术领域，尤其涉及一种密封结构及具有该密封结构的发电系统。
背景技术
光伏发电将太阳能这种清洁性的能源转化成电能，具有安全可靠，无噪声，无污染排放，无需消耗燃料，不受资源分布地域的限制的优势，并使光伏发电技术得到广泛的发展。
现有技术中的发电系统包括太阳能发电瓦，多个太阳能发电瓦依次搭接安装在具有坡面的建筑或其他空间。现有技术中，为了使两个相邻搭接的太阳能发电瓦之间有较好的密封性，从而起到防水的作用，会采用水泥砂浆粘结太阳能发电瓦，或在太阳能发电瓦的正面或背面粘直胶条，上下两片太阳能发电瓦搭接时依靠上侧的太阳能发电瓦的自重使直胶条挤压变形密封，从而达到防水要求。
但是，通过水泥砂浆粘结固定的太阳能发电瓦不易维修和更换；通过直胶条粘接两个太阳能发电瓦时，由于直胶条与太阳能发电瓦粘贴时会产生回弹力，粘贴胶条的胶固化前需要对直胶条采取一定的固定措施，否则直胶条与太阳能发电瓦之间会存在缝隙，使得直胶条无法起到防水作用，且直胶条的固定过程至少需要两个人才能完成，从而增加了太阳能发电瓦的连接工序，减低安装效率，提高安装成本。
申请内容
本申请的一个目的在于提供一种密封结构，以提高安装效率，降低安装成本。
为达此目的，本申请采用以下技术方案：
一种密封结构，所述密封结构沿其长度方向呈曲面结构；所述密封结构包括底壁，及连接于所述底壁的侧壁，太阳能发电瓦所述侧壁包括第一侧壁和第二侧壁，且所述第一侧壁、所述第二侧壁和所述底壁围成通槽，所述第一侧壁和所述第二侧壁与所述底壁设置倾角。

在本申请的描述中，需要说明的是，术语“长度方向”、“上”、“下”、等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，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申请的限制。此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性。

实施例1
本实施例提供了一种密封结构2，其主要但不局限应用于发电系统的太阳能发电瓦1的连接中，也可以用于其他外形为曲面的两个部件的连接中，以提高安装效率，降低安装成本。当然，太阳能发电瓦可以是平面、圆弧状、筒状或波浪状等。本实施例中，太阳能发电瓦1选用沿横向方向和纵向方向延伸的片状体，当沿着所述纵向方向观察时，太阳能发电瓦1呈波浪状，所述波浪状的波形是正弦型函数或类似正弦函数的波形。
所述纵向为沿屋顶雨水流下的方向，横向为与纵向垂直的方向。下文中的横向及纵向方向，与此相同。
如图1-3所示，本实施例提供的密封结构2，密封结构2可选用聚酯材料、热塑性三元乙丙橡胶或PVC(聚氯乙烯)等具有一定柔性的材料。密封结构2沿其长度方向(即图1所示的“L”方向)呈曲面结构；密封结构2包括底壁23，及连接于底壁23的侧壁，侧壁包括第一侧壁21和第二侧壁22，且第一侧壁21、第二侧壁22和底壁23围成通槽24，第一侧壁21和第二侧壁22与底壁23设置倾角。
曲面结构设置为多个连续的波形结构，波形结构包括至少一正弦波形，本实施例中所述的正弦波，也并非是标准数学意义上的正弦波，曲面结构大致为正弦波的波形结构即可，为了适应太阳能发电瓦1的结构，设置有多个正弦波形。当然，在此实施例中，密封结构2与波浪形太阳能瓦适配，设置为曲面。在另一实施例中，当待密封物为平面时，密封结构2则设置为平面。即密封结构2的形状与待密封物相适配。
本实施例中的第一侧壁21与底壁23所成夹角α大于90°且小于180°，第二侧壁22与底壁23所成夹角β大于0°且小于90°，优选地，第一侧壁21与第二侧壁22平行设置。第一侧壁21和第二侧壁22远离底壁23的一端与底壁23的距离相等，可以使第一侧壁21和第二侧壁22同时抵接到上方的太阳能发电瓦1，并同时起防水和支撑作用。
如图4所示，底壁23用于与一太阳能发电瓦1粘接，侧壁远离底壁23的一端与另一太阳能发电瓦1抵接。密封结构2在使用时，位于上方的太阳能发电瓦1抵接于密封结构2的侧壁，由于重力作用，上方的太阳能发电瓦1会向侧壁施加一定的压力，间隔设置第一侧壁21和第二侧壁22，会使侧壁具有较大的压缩量，使得上方的太阳能发电瓦1与密封结构2的接触面积增大，有效的提高密封结构2的密封和防水效果。
由于第一侧壁21向远离第二侧壁22的一侧倾斜延伸，第二侧壁22向靠近第一侧壁21的一侧倾斜延伸，当上侧的太阳能发电瓦1抵压到侧壁的上端时，第一侧壁21和第二 侧壁22会继续沿原来的倾斜方向倾斜，而不会沿相反的方向倾斜，因此在密封结构2的长度方向(如图1所示的“L”方向)上第一侧壁21和第二侧壁22的倾斜方向一致，没有安装缺陷，使得密封结构2具有很好的防水效果。
第一侧壁21与底壁23所成夹角α大于90°且小于180°，当水滴流至密封结构2处时，第一侧壁21对水滴具有较好的阻挡作用，防止水滴沿第一侧壁21流入通槽24内，使得密封结构2具有很好的防水效果。
本实施例中，第一侧壁21和第二侧壁22均包括第一倾斜部211和第二倾斜部212，第一倾斜部211连接于底壁23，第二倾斜部212连接于第一倾斜部211远离底壁23的一端，且第二倾斜部212的倾斜角度更大。第二倾斜部212远离底壁23的一端抵接于上方的太阳能发电瓦1，由于第二倾斜部212的倾斜角度更大，因此可以增大第一侧壁21和第二侧壁22与上方的太阳能发电瓦1的接触面积，增加防水效果，第一倾斜部211的倾斜角度较小，可以起到更好的支撑作用，使密封结构2保持稳定的防水效果。
如图2和图5所示，密封结构2为一体成型，该种形式的密封结构2粘贴方便，一个人可完成安装。密封结构2的两端均设置有台阶部25，且台阶部25设置于底壁23远离侧壁的一侧。密封结构2的端部预制台阶部25，避免太阳能发电瓦1的端部的凸起的卡接部与密封结构2干涉，保证密封结构2的防水效果。
密封结构2也可以由首尾相接的多段弯曲密封结构20构成。每段弯曲密封结构20的外形和尺寸可以相同，以便使用一个模具就可以生产构成密封结构2的多段弯曲密封结构20。
如图6所示，密封结构2可以由两段弯曲密封结构20构成，弯曲密封结构20的一端且靠近底壁23的一侧设置有台阶部25，将弯曲密封结构20粘结到太阳能发电瓦1上时，未设置台阶部25的一端相接，两个台阶部25分别位于整根密封结构2的两端。
如图7所示，密封结构2也可以由四段弯曲密封结构20形成，为了在同一模具上制作四段弯曲密封结构20，四段弯曲密封结构20上都不设置台阶部25。也可以分别在两段弯曲密封结构20的一端且靠近底壁23的一侧设置有台阶部25，另外两段不设置台阶部。将弯曲密封结构20粘结到太阳能发电瓦1上时，未设置台阶部25的一端与不设置台阶部25的两端弯曲密封结构依次连接，两个台阶部25分别位于整根密封结构2的两端。
将整根密封结构2分成两段或两段以上，本实施例中对弯曲密封结构20的具体段数不做限定，可以根据太阳能发电瓦1的尺寸做相应的调整，只要便于密封结构2的粘贴即可。将每段弯曲密封结构20分别与太阳能发电瓦1粘贴，并形成一个整体的具有曲面结 构的密封结构2。密封结构2的该种制作方式使得模具费用小，密封结构2单价较低，粘贴方便，一个人可完成密封结构2的安装。
本实施例中的密封结构2由三元乙丙橡胶制成，其硬度可以为HA45，密封结构2也可以由其他材料制成，只要能满足其防水效果即可。
实施例2
如图8和图9所示为本申请另一种实施方式的具体结构，这种实施方式与第一种实施方式的区别在于，本实施例中的夹角α与夹角β均大于90°且小于180°，优选地，夹角α与夹角β相等。当太阳能发电瓦1抵接于密封结构2的侧壁时，此时在密封结构2的长度方向(如图1所示的“L”方向)上第一侧壁21、第二侧壁22两者的倾斜方向相反，同时，第一倾斜部211与第二倾斜部212的倾斜方向一致，密封结构2与太阳能发电瓦1的贴合度好，防水性能较好。
本实施例中的其结构与实施例1相同，在此不再赘叙。
实施例3
如图10和图11所示为本申请第三种实施方式的具体结构，这种实施方式与第一种实施方式的区别在于，本实施例中的第一侧壁21与底壁23所成夹角α大于90°且小于180°，第二侧壁22与底壁23所成夹角β等于90°或大约为90°。第一侧壁21包括第一倾斜部211和第二倾斜部212，由于第二侧壁22与底壁23所成夹角β等于90°或大约为90°，当第二侧壁22抵接到上方的太阳能发电瓦1时，起防水作用的同时，能起到较好的支撑作用。
本实施例中的其他结构与实施例1相同，在此不再赘叙。
本申请的密封结构根据太阳能发电瓦结构及密封结构粘贴位置，制作出与太阳能发电瓦的曲面结构相一致的密封结构的曲面结构，使得密封结构与太阳能发电瓦完美贴合，密封结构与太阳能发电瓦粘贴时不存在回弹力，密封结构可直接连接到太阳能发电瓦上，不需要对密封结构采取额外的固定措施，提高了防水效果和安装效率，方便粘贴，降低了安装成本。且本申请中的密封结构的使用使得太阳能发电瓦便于更换和维修。
实施例4
本实施例提供了一种发电系统，包括若干个太阳能发电瓦1和上述实施例1-3中的任意一种密封结构2，纵向相邻的太阳能发电瓦之间设置上述的密封结构2。
密封结构2与太阳能发电瓦1的曲面形结构相贴合；纵向相邻的密封结构2的底壁 23粘接于一太阳能发电瓦1，侧壁远离底壁23的一端抵接于另一太阳能发电瓦1。
如图4、图9和图11所示，密封结构2的底壁23与位于下方的太阳能发电瓦1粘贴，防止密封结构2移动，并提高密封结构2的防水效果。密封结构2的侧壁抵接于上方的太阳能发电瓦1，上方的太阳能发电瓦1的重力作用使侧壁具有较大的压缩量，上方的太阳能发电瓦1与密封结构2能够较好的贴合，因此不必粘接。
密封结构2的第一侧壁21位于能够接触到水滴的外侧，当水滴沿着下方的太阳能发电瓦1向上流时，由于密封结构2与下方的太阳能发电瓦1采用密封胶粘贴，水滴无法渗透，防水性能较好，同时第一侧壁21能够较好的阻挡水滴，使水滴尽量少的渗入第一侧壁21的上端，使侧壁的上端满足防水要求。
本实施例中采用的密封胶可以是硅酮建筑密封胶，也可以是其他防水和粘结效果好的密封胶。
本实施例中的发电系统防水性能更加安全可靠，太阳能发电瓦1便于更换和维修。
显然，本申请的上述实施例仅是为了清楚说明本申请所作的举例，而并非是对本申请的实施方式的限定。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。凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请权利要求的保护范围之内。
