为了更清楚地说明本实用新型实施例或现有技术中的技术方案，下面将对照附图说明本实用新型的具体实施方式。显而易见地，下面描述中的 附图仅仅是本实用新型的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图，并获得其他的实施方式。
作为一个具体实施例，如图1、图2所示，本实施例提供了一种具有五边形截面的扭矩管1，用作旋转主梁，包括：管件主体11及设置在管件主体11内的腔体12。管件主体11的长度方向的截面为凸五边形，其包括按圆周方向首尾连接的第一边111、第二边112、第三边113、第四边114和第五边115，以形成封闭结构；管件主体11以第三边113的中垂线为轴对称结构，第二边112与第四边114对称设置，第一边111与第五边115对称设置，第二边112和第四边114分别与第三边113垂直连接。
进一步地，第一边111与第二边112所形成的内角为110°-120°，第一边111与第二边112所形成的内角可以为112°、115°、118°等。第二边112、第三边113及第四边114的长度相等。而第一边111与第五边115的长度相等，其二者的长度由第一边111与第二边112所形成的内角的大小来确定。例如：第一边111与第二边112所形成的内角为120°，第二边112、第三边113及第四边114的长度均为160mm，则第一边111和第五边115的长度均为100mm。
本实施例中，将扭矩管1的第三边113作为安装基准面，用于在安装光伏组件时对光伏组件进行定位，有助于安装人员将多个光伏组件安装在同一平面上；其中，第二边112和第四边114、第一边111和第五边115分别沿第三边113的中垂线对称，也即扭矩管1为沿第三边113的中垂线对称的结构。通过将扭矩管1的截面设置为上述的五边形结构，解决了市面上作为跟踪支架主轴的型材截面单一的问题，在保证强度，抗弯性，以及材料成本的情况下，给出了更多的截面供选择。
在另一实施例中，如图1、图2所示，在上述实施例的基础上，第一 边111与第二边112、第二边112与第三边113、第三边113与第四边114、第四边114与第五边115、第五边115与第一边111均倒圆角。将扭矩管1的各个边角均倒圆角，使得管件主体11在扭转时能够将力转移到弧形壁上，有效地进行扭矩的传递，也能优化扭矩管1的内部应力，增强牢度；倒圆角形成的过渡段能够降低管件主体11在连接处的内部应力，增加结构稳定性。
优选地，第二边112与第三边113的倒圆角半径等于第三边113与第四边114的倒圆角半径；和/或，第一边111与第二边112的倒圆角半径等于第四边114与第五边115的倒圆角半径，且等于第五边115与第一边111的倒圆角半径。本结构的扭矩管1为中心对称结构，其易于加工，结构稳固，并且此结构的扭矩管1没有外棱，便于同立柱上的回转轴承进行安装。
进一步地，第二边112与第三边113的倒圆角半径为第一边111与第二边112的倒圆角半径的两倍。例如：第二边112与第三边113的倒圆角等于第三边113与第四边114的倒圆角，其半径为20mm；第一边111与第二边112的倒圆角等于第四边114与第五边115的倒圆角等于第五边115与第一边111的倒圆角，其半径为10mm。
在另一实施例中，如图1、图2所示，在上述实施例的基础上，沿着管件主体11的长度方向延伸的任意位置均具有相同的五边形截面，五边形截面的每个边的厚度均相等。五边形截面的每个边的厚度为1.5mm-2.5mm，优选为2mm。扭矩管1可以为镀锌钢合金材料制成，或碳素钢制成，复合纤维或塑料材料也是可行的。
进一步地，具有五边形截面的扭矩管1还包括：焊缝，焊缝沿着与管件主体11的长度方向平行的外表面延伸。此结构的扭矩管1可以通过一体折弯四次或五次后焊接而成。或者，管件主体经冷弯成型工艺一体成型。 采用冷弯成型工艺一体成型的扭矩管1，可以方便安装、节省材料和加强强度，提高了扭矩管1自身的强度，降低了安装所产生的费用，同时也可以满足用户的个性化需求。
以下以D型管作为基准，对正方形管和上述实施例中五边形截面的扭矩管进行实验对比。其中，D型管的外径为133mm，厚度为3mm；正方形管的边长为140mm，四个边长均为2.3mm，四个倒圆角的半径均为30mm；五边形截面扭矩管的五个边依次为80mm、145mm、145mm、145mm、80mm，扭矩管1五个边的厚度均为2mm，第二边112与第三边113的倒圆角等于第三边113与第四边114的倒圆角，其半径为20mm；第一边111与第二边112的倒圆角等于第四边114与第五边115的倒圆角等于第五边115与第一边111的倒圆角，其半径为10mm。得到的实验数据如下：
类型 壁厚(mm) 材料成本 弯曲0° 弯曲60° 扭转承载力 扭转刚度
D型管 3 1.00 1.00 1.00 1.00 1.00
正方形管 2.3 96％ 135％ 123％ 112％ 130％
五边形截面扭矩管 2 94％ 194％ 151％ 121％ 155％
由上表可知，若D型管的材料成本为a，则正方形管的材料成本为0.96a，五边形截面扭矩管的材料成本为0.94a。在保证其他性能不降低的情况下，五边形截面扭矩管的材料成本低于D型管和正方形管，本截面的扭矩管可降低成本投入。
若D型管弯曲0°(刚产生弯曲时)所需的力为b，则正方形管弯曲0°所需的力为1.35b，五边形截面扭矩管弯曲0°所需的力为1.94b。在保证成本投入不增加的情况下，五边形截面扭矩管弯曲0°所需的力明显高于D型管和正方形管，则说明本截面的扭矩管抗弯性能明显高于D型管和正方形管。
若D型管弯曲60°所需的力为c，则正方形管弯曲60°所需的力为1.23c，五边形截面扭矩管弯曲60°所需的力为1.51c。在保证成本投入 不增加的情况下，五边形截面扭矩管弯曲60°所需的力明显高于D型管和正方形管，则说明本截面的扭矩管抗弯性能明显高于D型管和正方形管。
若D型管扭转承重变弯所需的力为d，则正方形管扭转承重变弯所需的力为1.12d，五边形截面扭矩管扭转承重变弯所需的力为1.21d。在保证成本投入不增加的情况下，五边形截面扭矩管扭转承重变弯所需的力明显高于D型管和正方形管，则说明本截面的扭矩管抗扭转承载力性能明显高于D型管和正方形管。
若D型管扭转变形所需的力为e，则正方形管扭转变形所需的力为1.30e，五边形截面扭矩管扭转变形所需的力为1.55e。在保证成本投入不增加的情况下，五边形截面扭转变形所需的力明显高于D型管和正方形管，则说明本截面的扭矩管抗扭转刚度性能明显高于D型管和正方形管。
与D型管和正方形管相比，五边形截面扭矩管具有更高的抗弯性、抗扭刚度和抗扭承载力，因此，在五边形截面扭矩管中执行相同任务所需的材料更少。五边形截面扭矩管与D型管和正方形管相比，增加抗弯性的同时，节约材料成本，以此达到降本的目的，同时截面结构新颖，也便于大规模生产建模；与同规格主轴减速机连接更省材料，节约材料成本，结构简单，美观。
在另一实施例中，如图3至图5所示，在上述实施例的基础上，本实施例提供了一种光伏支架，包括：扭矩管1、若干个并排间隔设置的立柱2和若干个光伏组件4。其中，扭矩管1包括：管件主体11及设置在管件主体11内的腔体12。沿着管件主体11的长度方向延伸的任意位置均具有五边形截面，五边形截面为凸五边形，其包括依次连接的第一边111、第二边112、第三边113、第四边114和第五边115；第三边113用于装设光伏组件，第二边112与第四边114分别与第三边113垂直设置，第一边111与第二边112所形成的内角等于第四边114与第五边115所形成的 内角。每个立柱2的顶部设置有轴承组件3，扭矩管1与轴承组件3适配连接，使得扭矩管1能够在立柱2上转动。若干个光伏组件4沿扭矩管1的轴线方向依次设置，并能够随扭矩管1一起转动。
具体地，如图4、图5所示，轴承组件3包括：安装台31、轴承座32和轴承33。其中，安装台31为U型结构，立柱2的顶端插设在U型结构的槽口内，并通过螺栓固定。轴承座32通过螺栓固定在安装台31上，轴承座32为环形结构，其内部设有轴承孔。轴承33为分体式结构，其包括上轴承331与下轴承332，上轴承331与下轴承332的外圆表面上均设有轴向的限位凹槽333。上轴承331的下端设有第一安装槽334，下轴承332的上端设有第二安装槽335，第一安装槽334与第二安装槽335共同组成安装孔，扭矩管1适配装设在安装孔内，使得第二边112的上段、第三边113、第四边114的上段分别与第一安装槽334的内侧壁贴合，第二边112的下段、第一边111、第五边115、第四边114的下段分别与第二安装槽335的内侧壁贴合。
本实施例中，将轴承33设计为分体式，这样的设计能够使得轴承座32无需分体设置，安装时只需将上轴承331和下轴承332放入轴承座32中，并且使轴承座32的上端卡设在上轴承331的限位凹槽333中，轴承座32的下端卡设在下轴承332的限位凹槽333中，再将扭矩管1穿设在安装孔中，即可实现扭矩管1的安装，简化了操作步骤，提高了安装效率。
值得说明的是，本实施例中也可以将轴承33设置为一体式结构，例如将轴承33可转动地安装于轴承孔内，轴承33具有第一连接端和第二连接端，轴承33还具有安装孔，供安装扭矩管1。通过将第一限位件连接于轴承22的第一连接端，第二限位件连接于轴承33的第二连接端，第一限位件和第二限位件分别位于轴承座32的两侧，以对轴承33与轴承座32之间的相对位置进行限位，以此实现轴承33与轴承座32的安装。当 然还可以使用其他的安装方式或安装结构，只要能实现扭矩管1与立柱2的转动连接安装方式或安装结构均在本实用新型的保护范围内。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详细描述或记载的部分，可以参见其他实施例的相关描述。
应当说明的是，上述实施例均可根据需要自由组合。以上所述仅是本实用新型的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本实用新型原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本实用新型的保护范围。
