Description

柔性联动斜单轴光伏遮阳系统 技术领域
本实用新型涉及太阳能发电领域。
背景技术
农业用的遮阳系统多采用遮阳幕布遮阳，遮阳幕布多为塑料编织幕遮阳网，遮阳网位于托幕线和压幕线之间，通过驱动边牵引合拢或是展开来调整农作物生长的光环境。现有的农业用的遮阳系统的遮阳网驱动要么展开(遮阳率100％)要么合拢(遮阳率10％左右)，不能调整遮阳的遮阳率，不能适应不同农作物不同生理时期的生长需求。
但由于遮阳网是柔性的，运行过程由于风的作用经常出现遮阳网缠卷传动机构发生故障。遮阳网的寿命5-8年左右，几乎每5年就更换一次，维护成本高昂。太阳光被遮阳网遮挡吸收，转化为热量散失，太阳能被白白浪费掉了。
现有的光伏温室大棚，光伏组件大多被当做为一种覆盖材料镶嵌到温室的维护结构中，对结构要求较高，导致成本上升，市场化推广缓慢。透光率固定，位置固定。不能满足农作物同生理阶段的对光的不同需求。可选农作物单一不能充分利用温室大棚进行生产。
现有的斜单轴光伏追踪系统成本高，稳定性差，抗风雪荷载能力差。支架多为钢结构桁架，钢材用量大成本高，传动也多采用昂贵的减速器和步进电机，市场推广缓慢。

参考图6，驱动杆9是通过U型螺栓17紧固到驱动杆支架连接件101上的，驱动杆支架连接件101再通过开口销102连接到纵杆82上。实际应用中，还能够通过焊接等其它方式将驱动杆9连接到纵杆82上。
参考图7，驱动杆支架连接件101上加工有突起103，起到增加驱动杆支架连接件101与驱动杆9连接摩擦力的作用，使连接更加可靠。
参考图8、图9，一对驱动杆9的两端分别连接主驱动支架10和被驱动支架11，因此中间换向支架8位于主驱动支架10与被驱动支架11之间。主驱动支架10和被驱动支架11分别套装在两根传动轴12上并与之固定连接。传动轴12通过轴承座13支撑在驱动立柱14上。驱动立柱14也能够通过拉绳拉结在地锚15上从而将力传递到地锚15。一根传动轴12穿过被驱动支架11并与之固定，该传动轴12通过轴承座13固定到驱动立柱14上。在另一侧，另一根传动轴12穿过主驱动支架10并与之固定，该传动轴12通过轴承座13固定到驱动立柱14上。主驱动支架10最少为一个。
参考图10和图11，主驱动支架10为具有力矩放大作用的支架。主驱动支架10两端固定柔性带18，柔性带18缠绕在驱动轴201上，从而实现驱动电机203至主驱动支架10的带传动，驱动主驱动支架10旋转。驱动轴201为动力输出轴，其动力来源于动力元件，动力元件可以是驱动电机 203。驱动电机203通过减速器202将扭力放大后使驱动轴201转动，驱动轴201通过柔性带18将力传导至主驱动支架10上，主驱动支架获得转动能量后顺时针或者逆时针旋转，从而带动驱动杆9沿着图8所示箭头方向运动，从而带动中间换向支架8、并进一步带到太阳能电池板1的翻转。在翻转过程中，羊眼螺栓5对端头换向支架4起到允许旋转并限制旋转角度的作用，结构简单，价格低廉，而太阳能电池板1的使用寿命长。利用光伏行业内的光伏追踪原理，通过控制驱动电机203的转向、行程及转动开机时间等要素，层层传导来控制太阳能电池板1的翻转角度，从而达到改变遮光率的目的。虽然在本实施例中驱动电机203采用的是带传动的方式驱动主驱动支架10，但实际使用中也能够采用齿轮传动等其它驱动方式。
从图12和图13可见，在驱动电机203对太阳能电池板1的翻转角度进行调节的过程中，通过太阳能电池板1的翻转，能够改变遮阴(遮光)率，能够为农作物生长提供更为精确的光环境，达到农作物增产和余光发电的目的。
虽然本实用新型是结合以上实施例进行描述的，但本实用新型并不限定于上述实施例，而只受权利要求的限定，本领域普通技术人员能够容易地对其进行修改和变化，但并不离开本实用新型的实质构思和范围。
