Description
本申请要求于2022年12月12日提交中国专利局、申请号为202211599370.2、发明名称为“光伏组件测试方法”的中国专利申请、申请号为202211610645.8、发明名称为“一种光伏构件”的中国专利申请、申请号为202223341463.3、发明名称为“一种光伏构件”的中国专利申请、申请号为202223361702.1、发明名称为“一种测试装置”的中国专利申请、的优先权,其全部内容通过引用结合在本申请中。
本申请涉及光伏组件技术领域,尤其涉及一种光伏组件测试方法及光伏压型钢板构件测试方法。
光伏压型钢板构件包括压型钢板和安装于压型钢板的光伏组件,光伏组件安装到压型钢板后,光伏组件上存在应力集中位置,当光伏组件受到荷载时,光伏组件的应力集中位置易发生破损、隐裂等问题,因此,将光伏压型钢板构件安装在建筑体表面时,需要预留运维通道,在光伏压型钢板构件安装、接线、检测、维修、更换过程中,操作者能够在运维通道内走动,降低了操作者在光伏组件表面踩踏导致光伏组件损坏的风险。设置运维通道,能够便于操作者的行走和安装,但运维通道处无法安装光伏压型钢板构件,导致建筑体上用于安装光伏压型钢板构件的面积减小,从而降低了建筑体上能够安装的光伏压型钢板构件的数量。
为了增加建筑体上能够安装的光伏压型钢板构件的数量,通常情况下会取消运维通道的设计,即在光伏组件的安装、接线、检测、维修、更换过程中,操作者需要直接踩踏在光伏组件上。
而现有技术中只强调了光伏组件的可踩踏性能较强,即在光伏组件的安装、接线、检测、维修、更换过程中,光伏组件受力损坏的风险较小,但现有技术中,对光伏组件安装于压型钢板后的可踩踏性能的测试方法没有既定标准,导致本领域技术人员无法正确评估安装到压型钢板上的光伏组件的可踩踏性能。

在一种具体实施例中,下面通过具体的实施例并结合附图对本申请做进一步的详细描述。
本申请实施例提供一种光伏压型钢板构件,光伏压型钢板构件是指通过结构密封胶或者机械形式将建筑用光伏玻璃组件(以下均简称为光伏组件2)与压型钢板1连接在一起、用于产生电力的、同时具有建筑物屋面构件功能属性的一体化产品,其中,压型钢板1是指将涂层板或镀层板经辊压冷弯、沿板宽方向形成波形截面的成型钢板,即如图1和图2所示,光伏压型钢板构件包括压型钢板1以及安装在压型钢板1上的光伏组件2,压型钢板1通过支座固定在目标单元上的檩条上,以实现光伏压型钢板构件的安装固定,其中,目标单元包括但不限于建筑体、地面、设备等。檩条的数量至少为两个,以下均以三个檩条为例;相邻的檩条之间的距离大于1m,具体地,相邻的檩条之间的距离为1m-2m,包括但不限于1.1m、1.2m、1.3m、1.4m、1.5m、1.6m、1.7m、1.8m、1.9m、2m等,檩条间距越小,则光伏压型钢板构件上的光伏组件2的

光伏压型钢板构件包括两两垂直的第一方向X、第二方向Y和第三方向Z,第一方向X与光伏组件2的宽度方向平行,第二方向Y与光伏组件2的长度方向平行,第三方向Z与光伏组件2的厚度方向平行。其中,第三方向Z与压型钢板的高度方向平行,第一方向X与第二方向Y中,一者与压型钢板1的长度方向平行,另一者与压型钢板1的宽度方向平行,以增加光伏组件2在压型钢板1上的安装方向的灵活性,以下均以第一方向X与压型钢板1的宽度方向平行、第二方向Y与压型钢板1的长度方向平行为例进行说明。
如图1、图2和图3所示,压型钢板1包括沿第一方向X分布的公肋11和母肋12,公肋11与母肋12之间设置有底板13,公肋11与底板13之间、母肋12与底板13之间均通过弯折部15连接,其中,弯折部15包括沿第一方向X延伸的第一弯折部151以及倾斜延伸的第二弯折部152,公肋11和母肋12均与第一弯折部151连接,第一弯折部151的另一端与第二弯折部152连接,且第二弯折部152远离第一弯折部151的一端与底板13连接,公肋11和母肋12之间设置有沿第三方向Z凸起的角驰部14,沿第一方向X,相邻的底板13通过角驰部14连接,其中,角驰部14的数量为一个,或者,多个角驰部14沿第一方向X间隔设置,角驰部14将压型钢板1分隔为多个槽体16,即角驰部14与部分底板13、公肋11围成槽体16,角驰部14与部分底板13、母肋12围成槽体16,相邻两个角驰部14与部分底板13围成槽体16。在第一方向X上,压型钢板1的公肋11、与之相邻的压型钢板1的母肋12通过锁边的方式固定连接形成锁边结构,以实现多个压型钢板1的连接固定。
在一种实施例中,如图1所示,在第一方向X上,光伏组件2通过结构密封胶与压型钢板1粘接固定,以简化光伏组件2与压型钢板1的连接结构;结构密封胶沿第二方向Y延伸,一个光伏组件2的一端通过一条结构密封胶固定在压型钢板1上,或者,一个光伏组件2的一端通过多条结构密封胶固定在压型钢板1上,即多条结构密封胶沿第二方向Y间隔分布。
其中,光伏组件2粘接固定在第一弯折部151上,即光伏组件2覆盖在角驰部14的上方,此外,光伏组件2还可以与角驰部14粘接固定,以增加光伏组件2与压型钢板1的连接稳固性;当角驰部14的数量为多个时,光伏组件2可以与一个角驰部14粘接固定,也可以与多个角驰部14粘接固定,以增加粘接灵活性。
在另一种实施例中,光伏组件2通过固定块固定在压型钢板1上,固定块可以为压块或夹具3,固定块沿第一方向X和/或第二方向Y分布在光伏组件2的边缘位置,即光伏组件2的长度方向的两端通过固定块与压型钢板1固定连接,和/或,光伏组件2的宽度方向的两端通过固定块与压型钢板1固定连接。当固定块为压块时,压块与压型钢板1固定连接,光伏组件2被压块固定,或者,光伏组件2被压块和压型钢板1夹持固定;当固定块与夹具3时,如图2所示,夹具3夹持固定在锁边结构和/或角驰部14上,夹具3夹持固定光伏组件2。以下均以固定块为夹具3、夹具3沿第一方向X夹持光伏组件2的两端、夹具3夹持固定在锁边结构上为例。其中,夹具3夹持固定在锁边结构上时,光伏组件2与第一弯折部151在第三方向Z上存在间隙,当光伏组件2受到向下的压力时,光伏组件2会向下弯曲变形,在一种实施例中,光伏组
件2向下弯曲变形时,光伏组件2与第一弯折部151之间仍存在间隙,在另一种实施例中,光伏组件2向下弯曲变形时,光伏组件2与第一弯折部151抵接,即第一弯折部151能够支撑光伏组件2,以减小光伏组件2的变形程度;此外,夹具3夹持固定在锁边结构上时,光伏组件2与角驰部14之间存在预设距离,或者,光伏组件2与角驰部14抵接,或者,光伏组件2与角驰部14粘接固定
如图1和图2所示,光伏组件2包括第一连接部23、第二连接部24和悬空部25,第一连接部23位于光伏组件2的边缘位置,用于与压型钢板1固定连接,第二连接部24位于角驰部14上方,用于与角驰部14固定连接或抵接,在第一方向X上,悬空部25位于第一连接部23与第二连接部24之间,和/或,悬空部25位于相邻的第二连接部24之间。具体地,如图1所示,当光伏组件2与压型钢板1粘接固定时,光伏组件2与第一弯折部151粘接固定的部分为第一连接部23;如图2所示,当光伏组件2与压型钢板1通过夹具3固定连接时,光伏组件2被夹具3夹持固定的部分为第一连接部23。
如图1和图2所示,光伏组件2包括沿第三方向Z相对设置的第一表面21和第二表面22,第一表面21位于光伏组件2朝向太阳光的一侧,在光伏压型钢板构件的安装、接线、检测、维修、更换等过程中,操作者需要踩踏在光伏组件2的第一表面21上,当操作者踩踏在光伏组件2的角部时,光伏组件2的角部的边缘位置会受到较大的应力,即光伏组件2的角部的边缘位置为光伏组件2的应力集中位置;当操作者踩踏在光伏组件2的悬空部25时,悬空部25的中间位置的变形程度最大,即悬空部25的中间位置为光伏组件2的应力集中位置。
当光伏组件2与压型钢板1粘接固定时,如图1所示,当操作者踩踏在光伏组件2上时,第二连接部24的边缘位置会受到较大的应力,即光伏组件2的第二连接部24的边缘位置为光伏组件2的应力集中位置。
当光伏组件2被夹具3夹持固定时,如图2所示,第一连接部23的边缘位置、相邻两个夹具3的中间位置均为光伏组件2的应力集中位置。其中,当光伏组件2与压型钢板1在第三方向Z上的距离较大时,操作者踩踏在光伏组件2上时,光伏组件2会向下弯曲变形,但光伏组件2不会与角驰部14抵接;当光伏组件2与压型钢板1在第三方向Z上的距离较小时,操作者踩踏在光伏组件2上时,光伏组件2会向下弯曲变形并与角驰部14抵接,此时,第二连接部24的边缘位置会受到较大的应力,即光伏组件2的第二连接部24的边缘位置为光伏组件2的应力集中位置;当光伏组件2的第二连接部24与角驰部14粘接固定时,第二连接部24的边缘位置为光伏组件2的应力集中位置。
操作者需要踩踏在光伏组件2的第一表面21上时,上述应力集中位置存在隐裂、损坏的风险,因此,在光伏组件2投入大批量生产及使用前,需要对光伏组件2进行踩踏测试,以便于评估安装于压型钢板1后的光伏组件2的可踩踏性能是否合格,降低了使用不合格的光伏组件2导致安装、接线、检测、维修、更换过程中光伏压型钢板构件损坏的风险。
具体地,如图4至图13所示,第一表面21上设置有测试点,在对光伏组件2进行可踩踏性能测试的过程,需要将负载块4放置在测试点上,使得负载块4的测试面
41的至少部分与第一表面21抵接,即通过负载块4对测试点施加预设荷载并维持预设时间,以模拟操作者在工作时,静止踩踏在第一表面21上时光伏组件2的受力情况,以增加测试结果的准确性和可靠性。
其中,负载块4放置在测试点上时,测试面41的一部分与第一表面21抵接,即测试面41与第一表面21的重合部分的面积小于测试面41的面积,使得负载块4的局部处于悬空状态;或者,测试面41的全部与第一表面21抵接,即测试面41与第一表面21的重合部分的面积等于测试面41的面积。
具体地,如图4至图8所示,测试点包括应力集中点,应力集中点位于光伏组件2上的应力集中位置,当光伏组件2安装在压型钢板1后,由于光伏组件2采取的安装形式不同,光伏组件2与其他结构的接触位置以及应力集中的位置也不同,以本申请的安装形式为例,应力集中点至少包括第一测试点26和第二测试点,第一测试点26和第二测试点27中,一者位于光伏组件2的角部,光伏组件2在悬空部25处的边缘为悬空边251,另一者位于悬空边251的中间位置,本申请实施例以第一测试点26位于光伏组件2的角部、第二测试点27位于悬空边251的中间位置为了进行说明。
其中,应力集中点还包括第六测试点2b和第七测试点2c,在第一方向X和/或第二方向Y上,第六测试点2b与第一测试点26对称设置,和/或,第六测试点2b与第一测试点26相对于第一表面21的几何中心中心对称设置;在第一方向X和/或第二方向Y上,第七测试点2c与第二测试点27对称设置,和/或,第七测试点2c与第二测试点27相对于第一表面21的几何中心中心对称设置。
在本实施例中,设置第六测试点2b,即测试过程中对光伏组件2的至少两个角部进行可踩踏性能测试,以增加角部的可踩踏性能测试结果的准确性和可靠性。设置第七测试点2c,即测试过程中对光伏组件2的至少两个悬空边251进行可踩踏性能测试,以增加悬空边251的可踩踏性能测试结果的准确性和可靠性。
当光伏组件2与压型钢板1粘接固定时,如图4至图8所示,应力集中点包括第三测试点28,第三测试点28位于第二连接部24的边缘。其中,测试点还包括第八测试点2d;在第一方向X和/或第二方向Y上,第八测试点2d与第三测试点28对称设置,和/或,第八测试点2d与第三测试点28相对于第一表面21的几何中心中心对称设置。

在本实施例中,若测试面41的面积较小,即S<50cm2,通过测试面41向光伏组件2施加预设荷载时,光伏组件2受到的压强较大,与实际安装过程中操作者对光
伏组件2施加的压强相差较大,降低了测试结果的可靠性;若测试面41的面积较大,即S>400cm2,通过测试面41向光伏组件2施加预设荷载时,光伏组件2受到的压强较小,与实际安装过程中操作者对光伏组件2施加的压强相差较大,降低了测试结果的可靠性。因此,50cm2≤S≤400cm2,增加了踩踏测试设备的测试结果的准确性和可靠性,进而提升了踩踏测试设备的工作性能。其中,在本实施例中,50cm2≤S≤105cm2时,以S=79cm2为例,负载块4模拟操作者的脚掌与第一表面21抵接,即模拟操作者在光伏组件2上踮脚站立;150cm2<S≤200cm2时,以S=157cm2为例,负载块4模拟操作者在光伏组件2上单脚站立;200cm2<S≤400cm2时,以S=314cm2为例,负载块4模拟操作者在光伏组件2上双脚站立。

在本实施例中,若第一测试面411的几何中心与第二测试面412的几何中心的距离较大或较小,即L9>500mm,或者,L9<100mm,使得第一测试本体42、第二测试本体43在第一方向X上的距离与操作者的双脚间距相差较大,导致踩踏测试设备的测试结果容易出现较大偏差。因此,100mm≤L9≤500mm,使得第一测试本体42、第二测试本体43在第一方向X上的距离与操作者的双脚间距相匹配,从而有利于提升踩踏测试设备的测试结果的准确性和可靠性。
在一种实施例中,第一测试面411为连续的、完整的平面,第二测试面412为连续的、完整的平面。

在本实施例中,若第一测试面411在第二方向Y上的长度较大、第二测试面412在第二方向Y上的长度较大,即L10>400mm,L11>400mm,或者,第一测试面411在第二方向Y上的长度较小、第二测试面412在第二方向Y上的长度较小,即L10<100mm,L11<100mm,使得第一测试面411、第二测试面412的轮廓尺寸与操作者的鞋底的轮廓尺寸差距较大,导致踩踏测试设备的测试结果容易出现较大偏差。因此,100mm≤L10≤400mm,100mm≤L11≤400mm,使得第一测试面411、第二测试面412在第二方向Y上的轮廓尺寸与操作者的鞋底的轮廓尺寸相匹配,从而有利于提升踩踏测试设备的测试结果的准确性和可靠性。
