本发明涉及平单轴光伏电站领域，具体是一种翘板式桥架结构及采用该桥架结构的平单轴光伏发电装置。
背景技术
由于土地及其光伏组件价格等等制约因素，光伏电站逐渐开始以平单轴跟踪支架来建设。单列平单轴一般能建成的长度大致在90米左右，电站为降低光伏组件的清扫成本，平单轴跟踪支架都会通过桥架连成1至2KM的长排，这样一长排可以只用一台清扫机器人清扫。
由于平单轴存在控制精度、安装精度等误差，及其90米长的扭矩管扭转角度误差，两列平单轴间的端部最终角度误差最大会达到12°左右；而且在各种突发状况(如大风情况)时，导致两组平单轴旋转角度的偏差更大，常规的桥架结构会出现桥架断开，需要后续人工重新将桥架连接复原，造成极大的人工成本。
鉴于平单轴光伏电站存在上述技术问题，亟需研发解决方案。

具体实施方式
下面结合附图和实施例对本发明做进一步说明。
第一实施例：翘板式桥架结构
参照图1和图2，本翘板式桥架结构100包括：套管结构110、第一回转梁120、第二回转梁130。第一回转梁120的一端通过万向节装置112连接套管结构110的一端；第二回转梁130的一端通过万向节装置112连接套管结构110的另一端。进一步参照图6和图7，在两个回转梁的所述另一端设有第一轴孔(即回转结构)134。回转梁的所述另一端的回转结构还可以是轴。
本翘板式桥架结构进一步还包括U形槽件140。图8中示出了U形槽件140的具体构造。如图8所示，U形槽件140的横板部(即第二横板部142)的一端设有缺口143，所述缺口143所在的端部的竖板部(即第二竖板部141)设有第二轴孔(即回转结构)144。U形槽件140在本翘板式桥架结构中作为限位件，用于限制回转梁与平单轴的檩条上的横梁的相对位置，具体应用将在后面的实施例中详细说明。
套管结构110用于实现桥的功能。图3和图4示出了套管结构110的构造。本套管结构110包括内管115和外管111，二者套设在一起，内管115和外管111沿轴线方向发生相对位移时，套管结构110的整体长度将发生变化。
此外，套管结构110还具有长度限位装置，所述长度限位装置包括弹簧114和限位绳113，所述弹簧114和限位绳113均穿设于套管结构内部，一端固定在外管111端部的螺杆上，另一端固定在内管115端部的螺杆上。当内管115相对外管111拉升到极限位置时，限位绳113对内管和外管产生牵扯，阻止进一步拉升，从而更好地避免内管从外管脱出。
图5中示出了一种万向节装置112的构造。本万向节装置112包括第一螺杆1121和第二螺杆1122，第二螺杆1122的一端具有孔，第一螺杆1121贯穿 该孔与第二螺杆1122组合在一起，第二螺杆1122可绕第一螺杆1121转动。
图6和图7中示出了一种回转梁的构造。本回转梁包括角钢132，角钢132具有第一横板部133和第一竖板部135，角钢132的一端形成有折板131，用于连接万向节装置112，角钢132的另一端在第一竖板部135设置第一轴孔(即回转结构)134。采用角钢，回转梁不但能与檩条上的横梁的顶部贴合，还能够与该横梁的外侧部贴合，形成侧向限位作用。需要指出，本发明的回转梁的主体不限于用角钢实现，还可以采用C型钢、U型钢、圆管、方管、异型管等，本发明对此不做限制。
第二实施例：一种平单轴光伏发电装置
主要是平单轴光伏发电装置的桥架的改进。桥架是设置在两个平单轴之间的、供清扫机器人从一个平单轴上的光伏组件行走至另一个平单轴上的光伏组件的装置。
图9和图10中示出了本平单轴光伏发电装置的桥架的构造。
参照图9，两个光伏组件201分别设置在两个平单轴205上，可由平单轴205带动旋转，实现对太阳光的跟踪。
平单轴205上固定有檩条203，檩条203与平单轴205大至垂直，檩条203上固定有横梁202，横梁202用于安装桥架，横梁202优选方管梁。
其中，桥架包括两个第一实施例的翘板式桥架结构100，两个翘板式桥架结构100关于平单轴205对称设置。
以图9中右后侧的翘板式桥架结构100为例，翘板式桥架结构100的第一回转梁120设置于左上侧的平单轴205，具体是在平单轴205的檩条203上的横梁202上。进一步结合图9和图10，横梁202上，在平单轴205上方的位置设置有转轴(即回转中心)204，第一回转梁120端部的第一轴孔134(见图6和图7)与该转轴204配合，使得第一回转梁120可绕转轴204回转。
翘板式桥架结构100的第二回转梁130设置于右下侧的平单轴205，具体是在平单轴205的檩条203上的横梁202上。具体设置方式同第一回转梁120。
图9中左前方侧的翘板式桥架结构100，以同样的方式设置于两个平单轴205。
如图9中，右下侧的平单轴205上的横梁202上翘时，右后侧的翘板式桥架结构100的第二回转梁130会贴合上翘的横梁202上翘，该翘板式桥架结构100的第一回转梁120也会跟随着上升；当该上翘的横梁202开始下降时，该翘板式桥架结构100的第一回转梁120和第二回转梁130都会跟随着下降，直至两个平单轴205上的横梁202平行时，两个翘板式桥架结构100均贴合平单轴上的横梁202。当一个平单轴205上的横梁202下降时，翘板式桥架结构100的一个回转梁会贴合不动的平单轴，而另一个回转梁会跟随着下降，直至套管结构110(见图1)中限位拉升到极限。
可见，上述实施例中，通过在常规的套管结构110的基础上增加了两个回转梁，两个回转梁在平单轴檩条上的方管上形成一个回转中心，使得回转梁可以回绕回转中心旋转，带动套管结构110跟随回转，这使得两个平单轴205处于任意角度时，套管结构110均不会脱开。
进一步结合图9和图10，第一回转梁120对应其回转中心处套设有U形槽件140，所述U形槽件140与所在横梁202上的转轴(即回转中心)204相连，所述U形槽件140的横板部的对应回转中心的位置设有缺口143，使得所述U形槽件140可跟随第一回转梁120一起绕回转中心回转。在第一回转梁120的回转中，当缺口143的底部碰到横梁202时，将无法再回转，达到了限制第一回转梁120与檩条上的横梁202的相对位置的目的。
同样，在第二回转梁130也设置有U形槽件140。
当第一回转梁120和第二回转梁130为角钢(如图6和图7所示)时，角钢的横板部(即第一横板部133)与横梁202的顶部贴合的同时，角钢的竖板 部(即第一竖板部134)还与横梁202的外侧部贴合，这样可以形成侧向限位，达到更稳固的效果。
其中的套管结构110还具有长度限位装置，也用于防止套管结构110的内管和外管脱开。参照图4，长度限位装置包括弹簧114和限位绳113，所述弹簧114和限位绳113均穿设于套管结构内部，一端固定在外管111端部的螺杆上，另一端固定在内管115端部的螺杆上，限位绳113优选钢丝绳。
第三实施例：另一种平单轴光伏发电装置
图11示出了另一种平单轴光伏发电装置。与图9所示平单轴光伏发电装置的区别在于：图9中平单轴205中的光伏组件的高度较小，为一块光伏板，而图11所示实施例中，平单轴205上的光伏组件201高度较大，是由多块光伏板构成。
需要指出，如无特别说明，上述“第一”、“第二”等类似术语用于区分相同名称的不同装置，不能解释为含有顺序、主次、重要程度等含义。
上述通过具体实施例对本发明进行了详细的说明，这些详细的说明仅仅限于帮助本领域技术人员理解本发明的内容，并不能理解为对本发明保护范围的限制。本领域技术人员在本发明构思下对上述方案进行的各种润饰、等效变换等均应包含在本发明的保护范围内。
