Description

一种多点平行同步驱动太阳能跟踪系统 技术领域
本发明属于光伏支架技术领域，具体涉及一种多点平行同步驱动太阳能跟踪系统。
背景技术
目前光伏支架的驱动跟踪系统中应用普遍的是单驱动跟踪系统，由一个减速机或推杆、线性执行机构等驱动机构单点驱动转动这样除驱动点以外形成自由长悬臂结构，容易产生大风情况下自由长悬臂扭曲，悬臂越长扭曲叠加原严重，造成组件及支架损坏风险，同时由于固有频率低也会增加共振风险。具体的，在单轴跟踪系统中，这种驱动机构的在大风作用下除了驱动点是固定锁定点，其它点均为自由活动部分。由于单套太阳能跟踪系统中从驱动点到系统最边缘的距离一般都在十几米甚至几十米的长度，在阵风作用下，容易产生形变、共振等风险，从而无法实现大风时候的多点共同锁定功能，系统的形变和震动会对系统会造成破坏，长期运行也会对其上承载的太阳能组件产生隐裂等风险。而且，目前在实际应用中，单套太阳能跟踪系统最大只能满足3个1500V光伏组串，对电站设计十分不便利。

具体实施方式
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对照附图说明本发明的具体实施方式。显而易见地，下面描述中的附图仅仅是本发明的一些实施例，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。
为使图面简洁，各图中只示意性地表示出了与本发明相关的部分，它们并不代表其作为产品的实际结构。
实施例1
如图1～4所示，为一种多点平行同步驱动太阳能跟踪系统，包括主轴3及用于支撑主轴3的多个立柱5，所述主轴3用于固设太阳能组件6；
还包括设于主轴3上的多点平行同步驱动装置，所述多点平行同步驱动装置包括传动连接的驱动机构1和若干级从动机构2；
所述驱动机构1的第一动力输出端与主轴3转动连接，以主轴3作为动力输出轴；所述驱动机构1的第二动力输出端固设于主轴3下方且与主轴3呈轴线平行；
若干级所述从动机构5沿主轴3间隔设置，所述驱动机构1的第二动力输 出端与相邻从动机构2的动力输入端沿轴向传动连接，相邻的两级从动机构2之间沿轴向传动连接；任一所述从动机构2的动力输出端均与主轴3转动连接；
从而，所述驱动机构与若干级从动机构传动配合实现对主轴的多点平行同步驱动转动。
本实施例中，驱动机构1将动力经第一、第二动力输出端分别沿轴向输出至主轴3、相邻的从动机构2，该从动机构2相应带动相邻的从动机构2轴向传动，进而使若干级从动机构2的动力输出端共同作用于主轴3，形成多点驱动主轴3同步转动的配合。应用该技术方案，当大风来临时，系统的多个驱动点就变成了多个固定锁定点，相应的使系统的抖动大幅降低，稳定性、可靠性得到大幅提升，从而可以实现分散风压、风扭，大幅提升系统工作的可靠性及稳定性。并且，驱动机构的两路动力沿主轴方向平行输出，使得系统在南北方向的运维便捷。此外，多点平行同步驱动装置根据实际所需承载的光伏组串的尺寸间隔设置，每个驱动装置到对应的承载系统边缘距离不超过10米，因此，在大风情况下本系统的变形大幅降低，受力降低，扭矩降低，对应系统成本也就大幅降低。在实际应用中，多点平行同步驱动装置包括传动连接的驱动机构1和2级从动机构2，每套系统由多点平行同步驱动装置来驱动，能在极端天气(尤其是强风)条件下，保证系统运行的稳定性；单套系统可以实现安装4个甚至更多1500V光伏组串(单个1500V光伏组串一般30个组件)。
作为优选的实施例，所述从动机构2在驱动机构1的一侧或两侧均匀间隔分布。从而可以进一步提高对主轴3多点平行同步驱动的稳定可靠性。
实施例2
如图1～4所示，为一种多点平行同步驱动太阳能跟踪系统，包括主轴3及用于支撑主轴3的多个立柱5，所述主轴1用于固设太阳能组件6；
还包括设于主轴3上的多点平行同步驱动装置，所述多点平行同步驱动装 置包括传动连接的驱动机构1和若干级从动机构2；
所述驱动机构1的第一动力输出端与主轴3转动连接，以主轴3作为动力输出轴；所述驱动机构1的第二动力输出端设于主轴3下方且与主轴3呈轴线平行；
所述驱动机构1包括固定在立柱5上的蜗轮蜗杆传动单元Ⅰ 10、作为第二动力输出端的传动齿轮11；蜗轮蜗杆传动单元Ⅰ 10包括蜗杆Ⅰ 100、作为第一动力输出端的蜗轮Ⅰ；所述传动齿轮11与蜗杆Ⅰ 100的下侧啮合，所述蜗轮Ⅰ与蜗杆Ⅰ 100的上侧啮合；且所述传动齿轮11的端面与蜗轮Ⅰ的端面相平行；所述蜗轮Ⅰ套设于主轴3上与主轴3转动连接；
若干级所述从动机构2沿主轴3间隔设置，所述驱动机构1通过传动齿轮11与相邻从动机构2的动力输入端沿轴向传动连接；且相邻的两级从动机构2之间沿轴向传动连接；任一所述从动机构2的动力输出端均与主轴3转动连接；
从而，所述驱动机构1与若干级从动机构2传动配合实现对主轴3的多点平行同步驱动转动。
本实施例中，驱动机构1中采用了蜗轮蜗杆传动结构，将动力经蜗轮Ⅰ、传动齿轮11分别沿轴向输出至主轴3、相邻的从动机构2，再相应带动邻近的从动机构2轴向传动，进而使若干级从动机构2的动力输出端共同作用于主轴3，形成多点驱动主轴3同步转动的配合。传统的蜗轮蜗杆传动机构，输入轴与输出轴呈垂直关系，而本实施例将蜗轮蜗杆的垂直输入输出转化为与蜗轮输出平行的两路同步输出，同时保留了蜗轮蜗杆结构的大保持力矩，在大风条件下可实现对主轴3的锁定作用。并且，本实施例的平行驱动可有效降低传动部件对太阳能组件6特别是双面组件的遮挡，使系统设计更加灵活。
在上述实施例中，所述传动齿轮11内固定连接有机械驱动轴4，所述机械驱动轴4随传动齿轮11可转动的固定在立柱5与蜗轮蜗杆单元之间，且所述机械驱动轴4与所述主轴1相互平行；所述驱动机构1通过机械驱动轴4与相 邻从动机构2的动力输入端传动连接，且相邻从动机构2之间通过机械驱动轴4传动连接。从而，通过机械驱动轴4实现驱动机构1及从动机构2之间的同步配合传动，驱动机构1将动力经蜗轮Ⅰ、传动齿轮11分别沿轴向输出至主轴3、机械驱动轴4，机械驱动轴4带动相邻从动机构2、再相应带动邻近的从动机构2轴向传动，进而使若干级从动机构2的动力输出端共同作用于主轴3，形成多点驱动主轴3同步转动的配合。在利用蜗轮蜗杆传动的大力矩的基础上，由于设计了机械驱动轴4与主轴3的两路平行同步输出，使机械驱动轴4平行布置在主轴3下方至立柱5顶部之间的空间内，充分利用空间，对于双面组件遮挡也只需要避开主轴就可以，使系统布置更加方便。
作为优选的实施例，所述驱动机构1还包括驱动电机，所述驱动电机的输出轴与蜗杆Ⅰ 100驱动连接，从而电机驱动蜗杆Ⅰ 100带动蜗轮Ⅰ转动，并带动传动齿轮11转动；或者所述驱动电机的输出轴与机械驱动轴4驱动连接，从而电机驱动机械驱动轴4带动传动齿轮11转动，并带动蜗杆Ⅰ 100、蜗轮Ⅰ转动。从而驱动电机的布置更加灵活方便。

本实施例的蜗轮蜗杆传动单元Ⅰ 10中的蜗轮Ⅰ将主轴3可转动的套设在内，并通过蜗轮外壳Ⅰ 101与立柱5连接而固定，从而，当蜗轮Ⅰ转动时，相应的带动主轴3定点跟踪旋转；通过立柱5实现了对主轴3及驱动机构1的固定支撑。并且，通过在主轴3及立柱5之间的空间内依托立柱5而设置驱动轴 座51，布置灵活紧凑，且不对太阳能安装组件产生干涉。
作为优选的另一实施例，所述从动机构2包括蜗轮蜗杆传动单元Ⅱ 20、作为动力输入端的连接件21；蜗轮蜗杆传动单元包括蜗杆Ⅱ 200、作为动力输出端的蜗轮Ⅱ；所述连接件21分别与机械驱动轴4沿轴向连接、与蜗杆Ⅱ 200沿竖向连接，用于将机械驱动轴4的轴向旋转传递至蜗杆Ⅱ 200；所述蜗轮Ⅱ与蜗杆Ⅱ 200的上侧啮合；且所述蜗轮Ⅱ套设于主轴3上与主轴3转动连接。
本实施例提供了从动机构2的优选设置形式，同样利用了蜗轮蜗杆传动结构，驱动机构将动力经蜗轮Ⅰ、传动齿轮11分别沿轴向输出至主轴3、机械驱动轴4，机械驱动轴4将轴向旋转传递至连接件21进而传递至蜗杆Ⅱ 200，从而，通过机械驱动轴4带动相邻的从动机构2同步轴向传动，进而使若干级从动机构2的动力输出端共同作用于主轴3，形成多点驱动主轴3同步转动的配合。在实际应用中，多点平行同步驱动装置包括传动连接的驱动机构4和2级从动机构5，每套系统由多点平行同步驱动装置来驱动，能在极端天气(尤其是强风)条件下，保证系统运行的稳定性；单套系统可以实现安装4个甚至更多1500V光伏组串(单个1500V光伏组串一般30个组件)。

更优的，所述主轴3设为平行的多排，相应的立柱5也设为平行的多排；相邻两排主轴3上的蜗杆之间对应传动连接，从而实现光伏跟踪系统的多排同步联动。具体的，第1排主轴3中的蜗杆Ⅰ 100与第2排、直至第n排主轴中的蜗杆Ⅰ 100一一对应传动连接，第1排主轴中的若干级蜗杆Ⅱ 200与第2排、直至第n排主轴3中的若干级蜗杆Ⅱ 200一一对应传动连接。在实际应用中，通过传动轴实现传动连接，从而实现多排同步联动。
从而，本发明驱动机构和从动机构的配合形式还能适应多平台跟踪系统(也即东西向多排跟踪系统的驱动)，通过将相邻两排跟踪系统的蜗杆进行传动连接，可以实现多平台跟踪系统的同步联动，使本发明技术应用范围更加广泛，适用性更强。
