Description

双面组件的光伏支架 技术领域
本发明涉及新能源领域的辅助装置，特别涉及一种双面组件的光伏支架。
背景技术
能源问题是一个国家的战略问题，同时也是在21世纪人类社会要保持高速可持续发展所面临的重大挑战之一。由于太阳能发电有如安全可靠，无污染，不受地域限制，无需消耗燃料，维护简便，建设周期短，建设的规模大小随意，不需要架设输线路，可以方便地与建筑物结合等等一系列的优点，这些优点是常规发电以及其它发电方式不能比拟的，因而太阳能发电成为目前各国研究得最多，发展也是最快的技术之一。
双面组件能够通过其正反两面吸收太阳能产生电能，相对于普通组件，双面增加了背面发电能力，使得双面组件比普通的组件发电能力得到提高，但是双面组件的背阳面阳光无法有效到达，导致双面组件的发电能力无法最大化。然而，由于地球自转和公转的影响，固定安放的双面组件对太阳能的利用率较低，特别是双面组件的背阳面，阳光主要通过漫反射到背面，背面阳光吸收少，导致双面组件增加的发电量减少。同时阳光的直射角度在南北回归线之间会发生变化，所以太阳能南北方向上斜射到双面组件上，减少了接受太阳的能量。
发明内容
为了解决该技术问题，本发明提供了一种双面组件的光伏支架，用于解决现有技术中双面组件吸收太阳能较少导致发电量减少的问题。
为了解决上述问题，本发明提供了一种双面组件的光伏支架，包括相互连接成排的多个支架单元，所述支架单元包括：
支撑架体，所述支撑架体包括供放置双面组件，且角度可变的支撑板以及设于所述支撑板底部的支撑架，所述双面组件贴近所述支撑板的一面形成背光面，所述支撑板与水平线的锐角角度在0～90°之间；
反光装置，所述反光装置连接于所述支撑架体，用于将太阳光反射至所述背光面上。
本发明的进一步改进在于，所述支撑架包括顶托于所述支撑板的立杆以及令所述立杆转动的驱动结构。
本发明的进一步改进在于，所述立杆包括固定于地面上的桩体以及连接所述桩体与所述支撑板的扭转管，所述驱动结构为一可伸缩的推杆，所述推杆连接所述柱体与所述支撑板以改变所述支撑板的角度。
本发明的进一步改进在于，所述反光装置的结构为“W”型，所述反光装置设于所述扭转管上，所述反光装置可将太阳光反射覆盖于所述背光面上。
本发明的进一步改进在于，所述反光装置与所述支撑板的锐角角度范围为5～45°。
本发明相比于现有技术的有益效果在于：
本发明通过将放置双面组件的支撑板根据太阳南北方向的照射角度预先设置成一定角度，使得阳光可以垂直射到双面组件上，这样双面组件的正反两面能够接收更多的阳光，使得双面组件的发电效率最大化。

具体实施方式
以下结合附图，对本发明上述的和另外的技术特征和优点进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明的部分实施例，而不是全部实施例。
本发明提供了一种双面组件的光伏支架。在传统的光伏支架上安装双面组件，由于地球的公转和自转，太阳从南北方向上斜射到双面组件上，一天之内太阳的东西方向上的照射角度也会发生变化，这就导致双面组件的发电量减少。本发明通过将放置双面组件的支撑板在南北方向上预先设置成一设定的角度，使得双面组件的表面与太阳的直射方向垂直，并且配合驱动装置在东西方向上的角度变化，使得双面组件的阳光吸收率增加，提高双面组件的发电效率。下面结合附图对本发明的双面组件的光伏支架的结构进行说明。
参阅图1、2，本发明为一种双面组件的光伏支架，该光伏支架包括了相互连接组成一整排的支架单元，每一个支架单元包括：支撑架体1、反光装置3。其中，支撑架体1又包括了支撑板11以及支撑架。支撑板11是用来放置双面组件2，并且支撑板11在东西方向的朝向角度是可以随着太阳的直射角度发生改变的，而支撑板11在南北朝向上与水平线的锐角角度α在0到90°之间，支撑架固定在支撑板11的底部，用于固定支撑板11。当双面组件2放置在支撑板11上，贴近支撑板11的侧面为背光面。为了将太阳光反射到双面组件的背光面上，在支撑架上固定一反光装置3，双面组件的上下表面同时吸收太阳光，增加了太阳光的利用率。
支撑架包括立杆以及驱动结构，立杆竖直顶托在支撑杆11的底部，立杆包括固定在地面上的桩体14，以及连接桩体和支撑板11的扭转管12，该扭转管12可以绕着自身的轴线发生转动；驱动结构为一根可伸缩的推杆13，推杆13的顶端连接支撑板11的底部，底端与桩体14固定连接，通过推杆13的伸缩使得支撑板11的角度发生改变。
反光装置3为多块反光板组成的“W”形状的结构，将其对称地固定在扭转管12上，调整反光装置3的角度，使得反射的太阳光可以完全覆盖在双面组件的背阳面上。一般反光装置的反光板与支撑板11组成的锐角角度在5°～45°之间。
举例说明，在安装时根据太阳在南北朝向上的照射角度将支撑板预先设置成一定角度，使得双面组件在南北朝向上能够与太阳的直射方向垂直，然后在东西方向利用驱动结构使得双面组件以天为周期发生转动。
本发明通过将放置双面组件的光伏支架的支撑板预先设置成与太阳光垂直的倾角，并配合驱动结构在东西方向上实现对太阳光的追踪，让双面组件能够接受更多的阳光，增加了双面组件的发电量。
以上所述的具体实施例，对本发明的目的、技术方案和有益效果进行了进一步的详细说明，应当理解，以上所述仅为本发明的具体实施例而已，并不用于限定本发明的保护范围。特别指出，对于本领域技术人员来说，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
