太阳能光热发电是实现大功率发电、替代常规能源的最为经济的手段之 一， 太阳能光热发电的三种方式各自优势缺点非常明显， 如： 塔式效率高， 但一次性投入大； 槽式成本低， 但相对塔式和蝶式效率低； 蝶式单机可标准 化生产， 但规模很难做大。
聚光光伏（ CPV )是指将汇聚后的太阳光通过高转化效率的光伏电池直接转 换为电能的技术， 聚光光伏也是实现低成本太阳能发电的一种选择， 聚光方 式中菲涅尔阵列方案也是其一。
线性菲涅尔太阳能聚光装置主要包括线性菲涅尔反射镜条系统及接收 装置， 该线性菲涅尔反射镜条系统包括线性反射镜条场， 该线性反射镜条场 由多个并排平行设置的反射镜条组成， 同时这些反射镜条可通过跟踪装置驱 动以跟踪太阳的运动， 持续保证将入射光反射到接收装置。 这些反射镜条反 射的太阳光被集中射向设置于这些反射镜条上方的接收装置内，通过该接收 单元将太阳能转化为热能或电能。通常一个接收装置可设置在多个反射镜条 之间， 以便接收该多个反射镜条反射的太阳光。
目前的线性菲涅尔太阳能聚光系统中，菲涅尔镜场水平直线地布置，贴近 基础面如地面， 带来一些不便的因素， 例如 1、 通常而言贴近地面的灰尘扰 动比较多， 且潮气较重， 太阳光线入射菲涅尔镜场的反射镜条后反射至高高 架起的接收装置， 经过两次尘埃层， 会有消光效应， 减少一定的光效； 2、 一定时间后菲涅尔镜场的反射镜条面灰尘增厚，严重减少了反射镜条的反射 能力， 需要较短周期的定期清洗， 同时因为菲涅尔镜场紧密排列布置于地面 之上， 操作人员并不方便清洗， 只有将反射镜条转动到垂直位置， 操作人员 从反射镜条之间的缝隙中进入进行操作， 如此反射镜条的宽度必须很宽， 例 如 2米， 此尺寸较大， 所需强度提高， 制作成本很难下降； 3、 反射镜条的 平板反射镜设计， 从理论上说， 平板反射镜条的宽度与接收器的宽度相近， 为了提高跟踪角度的容差性， 接收装置的接受宽度大于平板反射镜条的宽 度； 为了获得菲涅尔镜场的布置对称和更少的端部损失效应（会聚的光线偏 出接受器的轴向过多） ， 目前的镜场一般采用南北布置， 如此需要跟踪的范 围较宽， 例如正负 80度， 因此反射镜镜场特别是镜场边缘的反射镜条的容 差率很小 （或所需的接收装置的宽度很宽）， 为获得更高的聚光倍数和更好 的容差率， 反射镜镜场宽度很宽， 反射镜条的数目众多， 且接收装置被布置 的很高， 例如 18米以上， 即使如此能达到的传热介质的温度大约为 250°C 〜300°C , 同时因接收装置等的所需强度的提高， 对应的材料成本无法消减； 4、 反射镜镜场水平直线布置， 反射镜条在跟踪的过程中， 特别是每组反射 镜镜场的边缘反射镜条之间的遮光率很严重（前反射镜条的背部遮挡了后反 射镜条反射来的光线） , 降低了反射镜条的聚光效率； 5、 反射镜镜场直接 布置于地面之上， 占地面积较大， 土地利用率不高， 浪费了土地资源。 因此 如何提高菲涅尔的反射镜场的聚光效率， 检修和维护不便， 建设成本和场地 利用率等问题， 成为菲涅尔聚集技术的重大课题。 发明内容

下面将参照附图对本发明的具体实施方案进行更详细的说明， 在附图 中：

图 5是本发明的接收装置为光伏太阳能电池组的结构布置示意图； 图 6是本发明的接收装置为光热太阳能集热管的结构布置示意图。 具体实施方式 图 1 是本发明的一种实施例的菲涅尔聚集装置的阵列布置示意图。 常规的菲涅尔反射镜镜场 2可以设置贴近基础面沿水平方向直线布置， 为了获得更优的一些性能， 本聚集装置布置如图 la 所示， 菲涅尔聚集 装置的阵列由多个菲涅尔聚集装置单元阵列布置，例如 101、102和 103 , 每个菲涅尔聚集装置单元的整体结构 1 , 主要包括架高布置的反射镜镜 场 2、 接收装置 3和维护检修空间 10; 其中反射镜镜场 2包括多条平行 布置的反射镜条 4组成， 多个反射镜条 4整体在反射镜镜场垂直截面内 的反射镜条转轴位置沿凹形的曲线阵列布置， 以减少反射镜镜场 2内部 阵列布置的多个反射镜条 4之间的相互遮挡损失以获得较少的遮光率； 且反射镜镜场 2位于接收装置 3正下方的中间一定宽度内布置可改变位 置的反射镜条 4 以便腾出空间， 例如靠边垂直竖立， 形成中心通道 13 (见图 lb ) , 以方便人员和机械车辆通行进行高空作业， 当完成高空作 业后， 该位置的反射镜条 4回到原位， 继续进行反射聚光。 为了简化跟 踪驱动模式， 将反射镜镜场 2布置的凹型曲面拟合为两段直线布置， 如 图 1所示， 将原布置于凹形的曲线同侧上的反射镜条 4 , 例如 4-1、 4-3 和 4-5 , 拟合布置于同一条直线上， 且每片反射镜条 4之下布置有联动 连杆 11 , 以实现连杆方式的多反射镜条 4联动， 减化结构， 降低成本。 为提高反射镜镜场 2的机械强度， 在反射镜镜场 2下部设置拱形支撑结 构 12 , 用于支撑反射镜镜场 2。 多个反射镜条 4的宽度不一致， 其中反 射镜镜场 2中间位置布置的反射镜条 4-5较两边布置的反射镜条 4-1和 4-3的宽度要宽， 即每组反射镜镜场 1内部布置的反射镜条 4的宽度与 其布置在镜场内的位置有关， 所处位置越接近接收装置 3正下方的中心 位置， 其对应的反射镜条 4的宽度越宽， 在使各反射镜条 4获得相近的 光学容差能力的同时， 减少反射镜条数量； 反射镜条 4的宽度不宜制作 过大， 在节省材料和空间的同时， 也能提高反射镜条 4的反射镜精度； 因本设计的反射镜条 4的面型为柱面， 具有一定的会聚能力， 同时反射 镜镜场 2的一定布置， 例如南北布置， 所需跟踪角度的范围较宽， 且能 在绕自身的旋转轴 5旋转的过程中， 存在欠焦和过焦现象， 在保证一定 的高容差角度后， 反射镜条 4的宽度与接收装置 3的开口相当， 或者更 宽， 也能将不同时刻的太阳光反射至相同的空间内， 并且还有合理的容 差角度， 如此可以可靠地获得更高的聚集倍数， 获得更好的传热介质温 度， 降低装置的所需强度， 减少建设成本； 实际操作中反射镜镜场 2设 置为平板反射镜条和特殊柱面的反射镜条， 在获得较好的反射镜条聚光 的同时， 可以有效地控制降低成本； 在反射镜镜场 2的焦线位置布置接 收装置 3。
该菲涅尔聚集装置 1可以应用于光热领域，接收装置 3为线性集热器， 如图 1所示， 接收装置 3由一个或多个相邻平行布置的集热管， 如 U型集 热管 6 (图 1未示出， 见图 6 )组成， 每个 U型集热管的进出口在同一端， 相邻很近， 可在进口端设置自力式温控阀 14 , 不需电子闭环控制装置， 运 行稳定可靠， 实现简单； 通过自力式温控阀 14检测出口温度以控制 U型 集热管的流量， 保证稳定温度的输出的同时， 也保证的系统运行安全， 大 大简化控制， 经济可靠。 维护检修空间 1 0位于反射镜镜场 2 的下底部， 距地面一定高度， 例如 1. 5米， 以方便工作人员在镜场下方或后下方对反 射镜镜场 2检查和维修， 当对镜面进行清洁维护时， 镜条角度调整为竖立 或偏向下方。 另外如此的设计还可以将反射镜镜场 2相对远离地面， 起到 防潮湿和防灰尘的效果； 一定程度减少尘埃层对太阳光线的消光效应； 维 护检修空间 1 0 之下还可以设计成停车场或粮食、 花卉种植基地， 而且该 菲涅尔聚光装置还可以布置于建筑屋顶等等， 充分利用日益紧张的宝贵土 地资源。 该菲涅尔聚集装置 1也可以应用于光伏领域， 此时接收装置 3为 线性布置的太阳能电池组， 将反射会聚的光转化成电能输出， 线性布置的 太阳能电池组沿线性焦线平行的方向上可进一步设置复合抛物聚集器装 置 （CPC ) , 不需要在此维度内进行主动跟踪， 即可对焦线方向的光线进 行一定的会聚， 形成沿焦线方向排布的间断准二维聚光接收。
本菲涅尔聚集装置 1 的离地一定高度的维护检修空间 1 0的设计、 反 射镜镜场 2曲线布置设计、 反射镜条 4的柱面设计， 较之传统的菲涅尔镜 场水平直线地布置于地面上， 具有很多优点： 例如， 减少了贴近地面的灰尘 扰动比较多， 且潮气较重的弊端， 太阳光线避开尘埃层直接入射菲涅尔镜场 和接收装置， 减少消光效应， 提高聚光效率； 避开尘埃层， 具有更长的清洗 周期， 操作人员在定期清洗时轻松方便， 且操作环境优越， 在反射镜镜场 2 底下的阴凉区进行轻松的巡检及维护清洗； 反射镜条 4宽度不为了清洗人员 进入反射镜条之间而设计的很宽， 因此所需制作成本下降； 反射镜条 4设置 成柱面结构， 较之平板反射镜条， 具有一定的会聚能力， 在所需大范围跟踪 角度时， 只需反射镜条完成欠焦和过焦即可， 反射镜条 4的宽度可以与接收 装置 3的宽度相近， 甚至宽很多， 尺寸范围较宽， 具有更高的聚光倍数和更 好的容差率， 且每组反射镜镜场 2的总宽度不必设计的很宽， 因此接收装置
3可以布置的较低， 例如 6米， 所需支撑接收装置 3强度的较低， 所需成本 可以降低； 反射镜镜场 2的内凹曲面布置， 较水平直线布置在反射镜条的跟 踪过程中， 特别是反射镜镜场 2的边缘反射镜条之间的遮光率减轻很多 （前 反射镜条的背部遮挡了后反射镜条反射来的光线比例减少） , 增加了反射镜 条的聚光效率； 反射镜镜场 2离开地面设计维护检修空间 10 ,在满足操作人 员的优越环境下轻松完成检修、 维护和清洗的同时， 还可以在维护检修空间 10 的下部可以综合利用， 设置停车场或其他用途的场地， 而且该菲涅尔聚 光装置还可以布置于建筑屋顶， 最大幅度地提高土地利用率。
图 2是本发明的一种实施例的菲涅尔聚集装置整体结构布置示意图。 图 2所示菲涅尔聚集装置整体结构 1 ,主要包括反射镜镜场 2和接收装置 3; 反 射镜镜场 2由平行布置的反射镜条 4组成， 多个反射镜条 4例如 4-1、 4-3 和 4-5东西方向上规律阵列布置， 反射镜条 4的面型为柱面， 且能绕自身的 旋转轴 5旋转， 不同时刻的太阳光反射至相同的空间内； 多个反射镜条 4-1、 4-3和 4-5能将太阳光反射会聚于相同的空间内， 形成共同的焦线； 在反射 镜镜场 2的焦线位置布置接收装置 3 , 接收装置 3由多个相邻平行布置的 U 型集热管 6 (详见图 6 )组成。
图 3是本发明的一种实施例的反射镜镜场结构布置示意图。 如图 3所 示反射镜镜场 2包括多个反射镜条 4 , 例如 4-1、 4-3、 4-5、 4-8、 4- 12和 4-12 , 按照规律布置后将太阳光线会聚于接收装置 3附近（会聚点位置， 图中没有标示） ， 如图 3所示的 4-1 , 4-3 , 4-5所处的位置为太阳光正垂 直入射时所处的位置为太阳光一定角度入射时， 三个不同位置的反射镜 条 4完成反射任务时， 分别处于的位置状态； 实际操作中， 同一时刻的 任何不同位置的反射镜条 4对应将太阳光线，完成会聚光线于接收装置 3 附近的所处的位置状态都不相同； 如图 3所示， 反射镜镜场 2原本沿曲 线 A分布， 在曲线 A和接收装置 3的正底部一定宽度内布置可改变位置 的一条或多条反射镜条 4以便腾出空间， 例如靠边垂直竖立， 设置中心 通道 13 , 用以机械车辆通行和完成高空作业； 反射镜镜场 2内的反射镜 条 4的宽度随着位置不同宽度不一致， 越靠近接收装置 3正下方布置的 反射镜条 4的镜宽宽度越宽， 例如， 反射镜条 4-5宽度大于反射镜条 4-1 的宽度； 为了实现多个反射镜条 4的连杆方式的统一联动， 将曲线 A拟 合成两条直线， 直线 B和直线 C , 分两组独立地连杆 1 1统一跟踪。 图 3 右边示意了反射镜镜场 2的非工作状态， 即清洗状态， 当反射镜镜场 2 的反射表面不清洁， 且某天不适宜跟踪获取太阳能时， 开启清洗模式， 将反射镜镜场 2内的反射镜条例如 4-8、 4-10和 4-12 , 改变其位置为近似 垂直的状态， 对其进行清洗。
图 4是本发明的单个反射镜条的横截面结构示意图。 图 4示意了反 射镜条 4和接收装置 3的部分结构； 图中反射镜条 4的反射镜面为柱面， 且示意出了 -75° , 0, 75° 的三种太阳光线入射反射镜条 4对应于三个不 同的反射镜状态， 分别为 I, II, III, 反射镜条 4绕自身的旋转轴 5旋转， 反射镜条 4的面型为柱面， 具有一定的会聚能力， 同时反射镜镜场 2的 南北方向布置， 所需跟踪角度的范围较宽， 且能在绕自身的旋转轴 5旋 转的过程中， 存在欠焦和过焦现象， 在保证一定的高容差角度后， 反射 镜条的宽度与接收装置 3的开口相当， 甚至可以更宽， 也能将不同时刻 的太阳光反射至接收装置 3的空间内， 如此可以获得更高的聚集倍数， 获得更好的传热介质温度， 降低装置的所需强度， 减少建设成本。
图 5是本发明的接收装置为光伏太阳能电池组的结构布置示意图。 如图 5所示， 为了方便描述将光伏太阳能电池组的结构旋转为正面示意， 太阳能电池组由多个串联成线性布置的光伏电池 15组成， 布置于菲涅尔 太阳能据集装置的线性焦线位置上， 线性布置的太阳能电池组周边布置 两种复合抛物聚集器装置 （CPC ) 9 , 分别为沿线性焦线平行方向设置和 阵列的复合抛物聚集器装置 （CPC ) 9-1 , 对线性焦线垂直方向的光线进 行一定的会聚； 沿线性焦线的垂直方向 （径向） 上设置且沿线性焦线平 行方向阵列的复合抛物聚集器装置 （CPC ) 9-2; 太阳光线入射至复合抛 物聚集器装置（ CPC ) 9-2后，经反射至布置于复合抛物聚集器装置（ CPC ) 9底部光伏电池 15 , 如此可以实现增加线性焦线垂直方向上的容差性能， 同时可以减少在线性焦线平行方向上接收光伏电池的数目， 提高聚光倍 数和利用效率， 且形成沿焦线方向排布的间断准二维聚光接收； 多个复 合抛物聚集器装置 （CPC ) 开口位置可以设置高透过率薄玻璃 16进行封 盖， 与光伏电池 15形成密闭空间腔体， 保护复合抛物聚集器装置（CPC ) 9的反射涂层， 保证其使用效率和提高其使用寿命。
图 6是本发明的接收装置为光热太阳能集热管的结构布置示意图。 如图 6所示， 接收装置 3由至少一个 U型集热管 6组成， 多条 U型集热 管 6并列组成。 每个 U型集热管 6分别包括玻璃套管 7、 内层吸收管 8 和外层布置的复合抛物聚集器装置 （CPC ) 9。 在实施的运行中多个 U型 集热管 6的进出口在同一端， 且每个 U型集热管 6设置有自力式温控阀 14 , 不需电子闭环控制装置， 运行稳定可靠， 实现简单； 通过自力式温 控阀 14检测出口温度， 通过温度控制流量的大小， 保持一定恒定温度的 传热介质输出和运行安全； U型集热管 6的内层吸收管 8内部为传热介 质， 具有良好的吸收涂层的内层吸收管 8布置于玻璃套管 7内， 两者形 成的内部空间保持真空状态， 或处于动态真空状态， 以减少 U型集热管 内部的对流热损失且保护内层吸收管的吸收涂层， 延长使用寿命； 为了 提高太阳光线的接收能力， 增大接收装置 3的容差性、 获得更高的聚光 倍率和更好的光线接收的均勾性， 在 U型集热管 6装置的外部布置复合 抛物聚集器装置（CPC ) 9; 其开口处可以布置高透过率薄玻璃 16进行封 盖， 与玻璃套管 7形成密闭空间腔体， 保护复合抛物聚集器装置 （CPC ) 9的反射涂层， 保证其使用效率和提高其使用寿命。
显而易见， 在不偏离本发明的真实精神和范围的前提下， 在此描述的本 发明可以有许多变化。因此，所有对于本领域技术人员来说显而易见的改变， 都应包括在本权利要求书所涵盖的范围之内。本发明所要求保护的范围仅由 所述的权利要求书进行限定。
