Description
本申请涉及柔性光伏支架技术领域，尤其涉及一种紧固组件及柔性光伏支架。
目前市场上的柔性光伏支架主要是通过将两根或多根索（钢绞线）拉直，固定两端，将光伏组件直接连接到索上。光伏组件与索之间主要是通过U型螺栓或L型折弯件实现连接的。其中，U型螺栓需要先将相邻光伏组件通过连接片连接，之后在连接片上设置用于索穿设的U型螺栓。此种连接方式对于光伏组件受力传递有影响，在光伏组件承受负风压的时候，会造成连接片两端的光伏组件产生的拉力与索不在一个平面内，会造成额外的弯矩和扭曲。而采用L型折弯件时，L型折弯件将索夹紧会导致光伏组件的重心偏离索，此时在重力和受风的时候会对光伏组件和L型折弯件造成额外的弯矩和扭矩，导致柔性光伏支架结构不稳定。

目前市场上的柔性光伏支架主要是通过将两根或多根索（钢绞线）拉直，固定两端，将光伏组件直接连接到索上。光伏组件与索之间主要是通过U型螺栓或L型折弯件实现连接的。其中，U型螺栓需要先将相邻光伏组件通过连接片连接，之后在连接片上设置用于索穿设的U型螺栓。此种连接方式对于光伏组件受力传递有影响，在光伏组件承受负风压的时候，会造成连接片两端的光伏组件产生的拉力与索不在一个平面内，会造成额外的弯矩和扭曲。而采用L型折弯件时，L型折弯件将索夹紧会导致光伏组件的重心偏离索，此时在重力和受风的时候会对光伏组件和L型折弯件造成额外的弯矩和扭矩，导致柔性光伏支架结构不稳定。为解决上述技术问题本申请提供了一种柔性光伏支架。
请一并结合图1、图2、图6和图7，现对本申请提供的柔性光伏支架进行说明。该柔性光伏支架包括光伏组件10、索20和多个紧固组件30。如图3和图4所示，紧固组件30包括第一夹持板31、第二夹持板32及连接件（未示出）。第一夹持板31设有沿第一方向延伸的第一凹槽100和插设槽200。插设槽200包括沿第一方向相对设置的第一端和第二端。第一端和第二端中的至少一者露设于第一夹持板31。第二夹持板32包括插设部321和夹持部322。夹持部322设于插设部321。夹持部322上设有沿第一方向延伸的第二凹槽300。插设部321能够沿第一方向插设于插设槽200。插设槽200的槽口201能够对夹持部322进行避让，以方便夹持部322随插设部321移动。夹持部322能够通过插设部321绕第一方向相对第一夹持板31摆动，以使第二凹槽300靠近或远离第一凹槽100，在第二凹槽300靠近第一凹槽100时，第一凹槽100和第二凹槽300能够形成安装孔，第一夹持板31具有限位部311，以防止插设部321沿垂直于第一方向从插设槽200内脱出。在第二凹槽300靠近第一凹槽100时，连接件能够将夹持部322与第一夹持板31连接。具体地，如图2所示，紧固组件30设于光伏组件10，并将索20夹持于安装孔，再通过连接件将夹持部322与第一夹持板31连接，以使索20稳定处于安装孔。本实施例中，安装孔的围合形状与索20相匹配。索20为钢绞线。其中，第一方向平行于图3中箭头X所指方向。
综上，实施本申请实施例，将具有如下有益效果：上述方案的紧固组件30应用装备于柔性光伏支架中，除了使光伏组件10与索20之间良好连接之外，还能够保证柔性光伏支架的结构稳定。具体而言，该紧固组件30包括设有第一凹槽100和插设槽200的第一夹持板31、第二夹持板32及连接件。其中，第二夹持板32包括插设部321和设于插设部321的夹持部322。夹持部322上设有第二凹槽300。插设部321能够插设于插设槽200，插设槽200的槽口201能够对夹持部322进行避让。夹持部322能够通过插设部321绕第一方向相对第一夹持板31摆动，以使第二凹槽300靠近第一凹槽100形成安装孔，索20能够穿设于安装孔。连接件能够将夹持部322与第一夹持板31连接，以将索20夹持。如此通过增大与索20的连接面积，以提高紧固组件30与索20的连接稳定性，避免造成额外的弯矩和扭曲，导致柔性光伏支架结构不稳定。进一步地，夹持部322通过插设部321绕第一方向相对第一夹持板31摆动，同时，第一夹持板31具有限位部311，以防止插设部321沿垂直于第一方向从插设槽200内脱出，使得第一夹持板31和第二夹持板32形成有限活动的铰接结构，在进行索20的装配时，第一夹持板31和第二夹持板32能够具有一定的夹角，避免对索20的自由度过于限制，以方便索20的位置微调，避免产生弯矩和扭曲，同时，限位部311还能够避免索20在位置微调时驱动第二夹持板32与第一夹持板31分离，保证两者之间的连接稳定性，从而方便了索20的装配。最后，再通过连接件将夹持部322与第一夹持板31连接，将索稳定处于安装孔。
在一个实施例中，请一并结合图3和图4，插设部321能够与第一夹持板31形成插设槽200的内壁间隙配合。通过间隙配合以方便插设部321插入插设槽200，同时，插设部321能够相对第一夹持板31微动，进一步降低在夹持前对索20的自由度的限制，以方便索20的位置微调。
在一个实施例中，请继续参阅图3和图4，第一夹持板31包括本体312和弯折部313。限位部311设于本体312，以与本体312和弯折部313围设形成插设槽200。弯折部313一端与本体312连接，另一端弯折与本体312相对设置，并与限位部311间隔形成槽口201。当索20夹持于安装孔时，会对第一夹持板31和第二夹持板32提供反作用力，使得第一夹持板31和第二夹持板32之间产生相互远离的趋势，弯折部313具有与本体312相对设置的结构，能够对插设部321提供支撑，避免上述趋势发展，进而提升紧固组件30夹持索20的稳定性。
在一个实施例中，如图5所示，弯折部313具有与本体312相对设置的第一平面3131，插设部321具有能够与第一平面3131贴合的第二平面3211。如此通过第一平面3131和第二平面3211之间的贴合，增大了弯折部313和插设部321之间的连接面积，从而提升了弯折部313对插设部321支撑的稳定性。
在一个实施例中，请继续参阅图5，弯折部313具有第一弧面3132。第一弧面3132与限位部311间隔形成槽口201。插设部321上设有能够与第一弧面3132滚动配合的第二弧面3212。如此通过第一弧面3132和第二弧面3212的滚动配合，以提供夹持部322通过插设部321绕第一方向相对第一夹持板31摆动的支点，保证其摆动方向的稳定。同时，上述支点为第一弧面3132与第二弧面3212接触实现的，增加了摆动时，第一夹持板31和第二夹持板32间的接触面积，减小接触压强，避免第一夹持板31和第二夹持板32受损，提高了紧固组件30的寿命。
在一个实施例中，请一并结合图3和图4，插设部321背离第二弧面3212的一侧设有第三圆弧面3213。如此通过第三圆弧面3213的设置能够降低夹持部322摆动驱动插设部321时对第一夹持板31过于磨损，提高紧固组件30的寿命。
在一个实施例中，请一并结合图3和图4，第一夹持板31上设有第一连接孔400，第一连接孔400和插设槽200位于第一凹槽100的两侧，夹持部322上设有第二连接孔500，连接件插设于第一连接孔400和第二连接孔500，以将夹持部322与第一夹持板31连接。如此使得连接件以及插设部321和第一夹持板31的配合关系分别位于索20的两侧，以提升紧固组件30对索20的夹持稳定性。本实施例中，第一连接孔400和第二连接孔500均为螺纹孔，连接件上设有与其配合的外螺纹。在第二凹槽300靠近第一凹槽100时，第一连接孔400和第二连接孔500同轴，以方便连接件连接。
本实施例中，第一端和第二端均露设于第一夹持板31，以方便插接部从第一端和第二端中的任意一者插入插设槽200。可以理解为在其他实施例中，第一端和第二端中的一者露设于第一夹持板31，另一端密封，使得密封处能够阻止插设部321移动，进一步地降低第二夹持板32的自由度，避免索20的位置微调，带动第二夹持板32与第一夹持板31分离。
在一个实施例中，连接件设于光伏组件10。具体地，第一夹持板31与光伏组件10贴合，连接件依次穿过第二夹持板32和第一夹持板31与光伏组件10连接，能够通过一个连接件实现对索20的夹持和与光伏组件10连接。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所揭露的仅为本申请较佳实施例而已，当然不能以此来限定本申请之权利范围，因此依本申请权利要求所作的等同变化，仍属本申请所涵盖的范围。
