Description

一种定日镜的反射镜用支撑调形装置 技术领域
本发明涉及一种支撑调形装置， 特别涉及一种太阳能高温发电中定日镜的反射镜用支 撑调形装置。
说
背景技术
太阳能发电技术是通过聚焦集热将太阳能转换为热能进而转换为电能， 它是最有应用 前景的太阳能利用方式之一。 其中， 定日镜用于聚焦并反射太阳光。
现有的定日镜是由多个反射镜按照一定的排列组书合而成。 目前， 定日镜中的反射镜的 镜面多为平面， 经过反射后的光线变得发散， 不容易聚焦。 因此每个反射镜都需要调整成 一定的曲率、 以及俯仰和方位角度， 使经过调整的定日镜整体聚焦。
基于此， 有发明人采用四点支撑、 一点拉伸的结构调节反射镜的玻璃微弧曲面， 以保 证反射镜的聚光效果。 此结构的定日镜虽然能够聚焦， 但是由于四个支撑点在支撑的同时 还用于调节方位和角度， 所以在安装时容易互相干扰， 调整难度比较大。 另外， 由于受到 结构本身的限制， 必须要将反射镜安装到支架上之后才能对光斑进行调整， 因此调整速度 比较慢， 不利于批量化的安装调整。
另有发明人设计了一种反射镜通过拉伸预先成型， 然后安装到大型支架上的调整结构， 由于反射镜预先成型后要通过 4-8 个点固定到定日镜的大型支架上， 因此固定点众多， 而 且距离较远， 在安装时容易互相干扰， 造成玻璃支撑架的内部应力增大， 进而影响已经预 先成型的反射镜的反射效果。
因此以上两种结构均存在结构复杂， 加工难度大， 使用不便， 不易安装调节及调整效 果差的缺陷。 发明内容
本发明针对现有技术的缺陷， 提供了一种结构简单， 调节方便且调整效果好， 易于加 工制造的定日镜的反射镜用支撑调形装置。
为了实现上述目的， 本发明实施例采取的技术方案是： 一种定日镜的反射镜用支撑调 形装置， 设置在所述定日镜的反射镜的背面并且与所述定日镜的支架固定连接， 所述支撑 调形装置包括调形部件和调整部件， 所述调形部件用于调整所述反射镜的曲率， 所述调整 部件用于调整所述反射镜的俯仰及角度， 所述调形部件包括至少四个调形组件， 其中至少 有一个调形组件设置在所述反射镜中央的驳接爪中心套上， 其余的调形组件设置在所述反 射镜的边缘， 并分别通过各自的驳接爪支撑臂与所述驳接爪中心套相连， 所述调形组件包 括吸盘及可调紧固件； 所述调整部件对应设置在所述驳接爪中心套的侧部， 所述调整部件 包括过度件及调整紧固件， 所述过度件与所述支架固定连接， 所述调整紧固件设置在所述 过渡件与驳接爪中心套之间。
本发明实施例的有益效果： 本发明所述的支撑调形装置包括调形部件和调整部件。 通 过调节调形部件中螺栓， 改变反射镜的曲率， 达到反射镜聚光的目的， 调整完毕， 将调节 好的螺栓固定， 单元反射镜的调形结束。 之后通过调整部件改变反射镜的俯仰和方位角度， 保证每个定日镜上所有的反射镜的光斑重合。 相比现有技术， 由于本发明采用将反射镜调 形部件与反射镜的调整部件分开调整的结构， 因此本发明在调整过程中减少了干扰， 不仅 使用方便， 易于调节， 而且经试验证明聚光调节效果更好， 方位角度调节范围更大。
因此本发明具有结构简单， 调节方便且调整效果好， 易于加工制造的优点。 附图说明

为使本发明的目的、 技术方案和优点更加清楚， 下面将结合附图对本发明实施方式作 进一步地详细描述。
实施例 1
如图 1-8所示， 本发明所述一种定日镜的反射镜用支撑调形装置的实施例 1， 所述支撑 调形装置， 设置在所述定日镜的反射镜 1的背面并且与所述定日镜的支架 16固定连接。 所 述支撑调形装置包括调形部件和调整部件。 所述调形部件用于调整所述反射镜 1 的曲率。 所述调整部件用于调整所述反射镜 1的俯仰及角度。
如图 1-4所示， 本实施例中所述调形部件包括一个中心调形组件和四个边缘调形组件。 具体实施时， 可根据反射镜的大小设置调形组件的数量为四个或四个以上。
如图 1及 4所示， 中心调形组件设置在所述反射镜 1中央的方形的驳接爪中心套上， 中心调形组件包括调形吸盘 7及可调紧固件。 本例中， 所述可调紧固件是压紧螺母 8、 调形 螺杆 9及调节螺母 10， 具体实施时， 还可以采用球头螺栓及螺母结构。 本例中， 调形螺杆 9的螺杆端通过两个调节螺母 10和一个调形片 11固定在方形驳接爪中心套 6上，调形螺杆 9的另一端通过压紧螺母 8固定在调形吸盘 7上。调形螺杆 9具体的是将螺杆端穿过调形片 11并通过两个调节螺母 10固定在调形片 11 的两侧。 通过旋动调形片 11两侧的调节螺母 10实现反射镜 1的曲率调节。 本例中， 调形片 11是角钢。 另外， 调形螺杆 9的螺杆端还可 直接和方形驳接爪中心套 6连接， 参见图 9如本发明实施例 2所示。 此两种中心调形组件 均具有结构简单， 调节方便， 成本低廉的优点。
如图 1及 2所示， 其余的四个边缘调形组件分别通过各自的驳接爪支撑臂 5连接在所 述方形驳接爪中心套 6上。 每个边缘调形组件包括吸盘 2及可调紧固件。 所述可调紧固件 为螺栓 4及螺母 3。 螺栓 4一端连接在吸盘 2上 （参见图 5及图 6)， 螺栓 4另一端穿过驳 接爪支撑臂 5并由设置在驳接爪支撑臂 5两侧的螺母 3固定。 通过旋动螺母 3实现反射镜 的曲率微调。
其中所述驳接爪支撑臂 5与方形驳接爪中心套 6采用焊接结构， 此方式能很好的保证 驳接爪的强度， 进而确保反射镜 1平面反光的规则性， 从而保证反射镜 1的聚光效果。
所述调整部件对应设置在方形驳接爪中心套 6 的外侧部， 所述调整部件包括过度件及 调整紧固件。 本例中， 调整紧固件采用调节螺栓 12和调节螺母 10， 具体实施时， 还可以采 用球头螺栓及螺母结构。 具体地， 如图 4所示， 本例中， 所述过度件为过度盘 14， 过度盘 14通过压紧螺栓 15固定在支架 16上。 如图 8所示， 为了安装方便， 过度盘 14上有四个均 布的月牙糟和一个中心圆孔。 中心圆孔用于压紧螺栓 15和支架 16固定。 具体实施时， 根 据过度盘 14的大小设置所述月牙槽的数量为三个或三个以上的其他数量。 如图 7所示， 所 述方形驳接爪中心套 6 用方钢焊接而成， 其上设有与所述月牙槽相配的螺纹孔。 所述月牙 槽及所述螺纹孔内穿过调节螺栓 12。 调节螺栓 12穿过方形驳接爪中心套 6和过度盘 14， 并通过调节螺母 10锁紧。 其中调节螺栓 12既起到固定作用， 同时也起到调节方位、 角度 的作用， 只要调节调节螺栓 12下端的调节螺母 10就可以很方便的调整反射镜 1的方位、 角度。
安装时将反射镜 1放在平面上， 反射面向下， 通过粘接胶 13将吸盘 2固定。 方形驳接 爪中心套 6上安装调形片 11后将方形驳接爪中心套 6与调形吸盘 7进行固定， 根据反射镜 1与吸热器之间的距离， 调整调形螺杆 9， 使反射镜达到理想的曲率， 然后拧紧调节螺杆的 调节螺母 10， 反射镜 1的面型固定。
通过压紧螺栓 15将过度盘 14与支架 16进行固定。 将调节螺栓 12安装在方形驳接爪 中心套上并预紧， 将四个调节螺栓 12安装在过度盘 14上， 根据反射镜单元的光斑位置， 对称的扭动调节螺栓 12， 通过调节螺栓 12的上下位移， 调整光斑的上下位置， 通过调节螺 栓 12相对于过度盘 14的左右位移， 调整光斑的左右位置， 最终将每个定日镜上所有的小 光斑进行重合， 达到高效聚光的目的。
经过实际实验验证， 利用本发明实施例 1 所述支撑调形装置安装、 调整并将一个定日 镜所有单元镜光斑进行重合所需要的平均安装时间仅有 1 个小时左右， 相比之前现有技术 平均安装时间需要 2-3小时， 效率大大提高； 并且利用本发明可使 300米距离时 100平米 定日镜的光斑控制在 10平方米， 相比之前现有技术所能控制的 16平方米， 光斑质量大大 提高， 更加有利于发电。 相比现有技术， 由于本发明采用将反射镜调形部件与反射镜的调 整部件分开调整的结构， 因此本发明在调整过程中减少了干扰， 不仅使用方便， 易于调节， 而且经试验证明聚光调节效果更好， 方位角度调节范围更大。
实施例 2
如图 9-11所示， 本发明所述一种定日镜的反射镜用支撑调形装置的实施例 2， 其与实 施例 1 的区别在于用于方位及角度调整的调整结构， 其他相同之处本例不再赘述。 如图 9 所示， 实施例 2中的调整结构包括圆形驳接爪中心套 17、 调节盘 19及调节螺栓 20。 调节 盘 19固定在支架 16上， 调节盘 19上均布四个螺纹孔， 调节螺栓 20—端通过调节螺母 21 和球面垫圈 18固定在和圆形驳接爪中心套 17上， 只要拧调节螺栓 20的另一端， 就可以很 方便的调整反射镜 1的方位、 角度。 实施例 1中所述调整部件的结构同样适用于实施例 2。
综上所述， 由于本发明采用反射镜曲率调整和方位、 角度调整分离， 所以相比现有技 术， 本发明在调整过程中减少了干扰， 不仅使用方便， 易于调节， 易于加工， 生产成本低， 而且经试验证明聚光调节效果更好。
以上所述仅为本发明的较佳实施例， 并不用以限制本发明， 凡在本发明的精神和原则 之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本发明的保护范围之内。
