现有的便携式太阳能电池主要采用光伏板或可折叠的柔性光伏板, 通过光伏板 的表面直接接收太阳光来产生电能。 由于通常并不具有安装支架, 因此在使用 时, 便携式太阳能电池的光伏板的受光面与太阳光会产生一个南北方向的倾角 , 而这会降低光伏板的发电能力。 此外, 便携式太阳能电池通常也不具备聚光 能力, 因此, 不仅增大受光面积会带来明显的成本升高, 而且其太阳能利用效 率也受到限制。

发明实施例
本发明的实施方式
[0014] 具体实施方式
[0015] 实施例 1
[0016] 依据本发明的便携式太阳能装置的一种实施方式可参考图 1。 图 1示出了这种类 型的装置的一个基本结构的示意图, 包括光能利用装置 110 , 柔性反射面 120, 挂杆 131以及撑杆 132。
[0017] 光能利用装置 110可包括光伏板 111。 本发明中的光伏板泛指任何直接将光能转 换为电能的光电转换器件, 包括各种半导体光伏板、 光伏薄膜、 量子点光电转 换器件、 光电转换材料等。 尤其地, 本发明中的光伏板可优选采用柔性光伏板 或可折叠的光伏板。 光伏板 111的表面即为光能利用装置的受光面。 在其他实施 方式中, 光能利用装置还可进一步包括聚光装置以提高聚光比。 除了采用传统 的中心聚光装置 (即将光线汇聚到透镜光学中心处的装置) 以外, 可优选采用 侧面聚光装置 (通过反射的方式引导和汇聚侧面光线的装置, 这种装置通常顶 部开口较大而底部开口较小, 内壁为反射面) , 例如锥形聚光漏斗或条形聚光 槽等, 光伏板可设置在聚光漏斗或聚光槽的底部。
[0018] 柔性反射面 120的一侧边缘 (以下称为“上边缘”) 通过基本横向延伸的挂杆 131 被支撑在基本竖向延伸的撑杆 132的上方。 柔性反射面的与挂杆相对的另一侧边 缘 (以下称为“下边缘”) 设置在光能利用装置 110的受光面的一侧, 使得柔性反 射面与光能利用装置的受光面形成一张角。 例如, 柔性反射面的下边缘可通过 一对地钉 133和 133'固定在地面上, 或者也可以固定在光能利用装置 110的相应的 侧边上。 为便于携带, 柔性反射面 120可通过挂杆 131被卷起和收存。 撑杆 132可 设计为一端便于插入地面的形式, 使得能够方便地撑起和展开柔性反射面。
[0019] 本实施例中, 柔性反射面 120与光能利用装置 110的受光面的张角为钝角, 这使 得能够扩大受光面获得的太阳光的范围, 让一些原本无法直射到受光面上的太 阳光 LL能够被引导到受光面上。 在这种情况下, 张角优选地不大于 135度。 在其 他实施方式中, 张角也可以为锐角, 以利于改善太阳光入射到受光面上的入射 角, 在这种情况下, 张角优选地不小于 45度。
[0020] 本实施例中, 只示例性地示出了设置在光能利用装置的一个侧面的一个柔性反 射面, 且一个柔性反射面只采用一个撑杆来支撑。 在其他实施方式中, 也可以 设置更多个, 例如 2或 3或 4个柔性反射面, 且每个柔性反射面可采用两个撑杆来 支撑。 优选地, 撑杆的竖向高度能够被调节以调整柔性反射面与光能利用装置 之间的张角。 或者, 还可设置进一步的支撑结构以更好地调整柔性反射面的形 态。
[0021] 由于依据本发明的便携式太阳能装置能获得较高的聚光比, 因此, 作为一种优 选的实施方式, 本实施例还包括热能利用装置 140, 以实现更高的太阳能利用效 率。 热能利用装置设置在光能利用装置下方并与其导热连接, 从而进一步利用 光能利用装置产生的热量。 热能利用装置可以是热能存储器 (例如热水器) 或 热能发电机 (例如斯特林发电机或蒸汽发电机) 等。
[0022] 实施例 2
[0023] 依据本发明的便携式太阳能装置的另一种实施方式可参考图 2, 包括光能利用 装置 210, 水箱 240, 柔性反射面 220, 挂杆 231以及撑杆 232和 232'。
[0024] 本实施例中, 光能利用装置 210采用光伏板 211。 柔性反射面 220的上边缘由一 对撑杆 232和 232'来支撑。 具体地, 撑杆 232和 232'分别支撑在挂杆 231的两端。 柔 性反射面 220的下边缘固定在光伏板 211—侧。 水箱 240紧贴在光伏板 211的下方 , 既用于提供热水, 也用于为光伏板散热。
[0025] 本实施例与实施例 1的主要区别在于: 柔性反射面 220与光能利用装置 210之间 的张角为锐角。 换言之, 实施例 1中, 光能利用装置处于柔性反射面的外侧, 而 本实施例中, 光能利用装置处于柔性反射面的内侧。 这种结构使得, 当光能利 用装置水平设置而太阳光 LL倾斜入射时, 柔性反射面不仅可用于增大收光面积 , 也可用于改善光线的入射角。 而改善入射角能起到提高光能利用效率的作用 , 这一优点是张角为钝角的侧面聚光装置所不具有的。
[0026] 作为一种优选的实施方式, 本实施例还包括一基本竖直放置的菲涅尔透镜 250 以进一步加大系统的聚光比, 以满足更高的性能要求。 本发明中的菲涅尔透镜 可采用单面或双面菲涅尔透镜, 且可以为线型菲涅尔透镜或部分菲涅尔透镜。 所称“单面”是指一面为齿面另一面为光滑面, 所称“双面”是指两面均为齿面。 所 称“线型”是指透镜的聚焦中心不是一个点而是一条线。 所称“部分”是指菲涅尔透 镜的齿面不是完整的对称图案而只是其中的一部分, 如图 3所示。
[0027] 本实施例中, 菲涅尔透镜 250采用向下折射的线型菲涅尔透镜, 固定在一对撑 杆 232和 232'的顶部, 其聚焦中心线的延伸方向可以与光伏板的延伸方向一致。 在其他实施方式中, 菲涅尔透镜也可设置在光能利用装置的上方。
[0028] 实施例 3
[0029] 依据本发明的便携式太阳能装置的另一种实施方式可参考图 4, 包括光能利用 装置 310, 柔性反射面 320, 挂杆 331, 撑杆 332和 332'以及菲涅尔透镜 350。
[0030] 本实施例中, 光能利用装置 310采用可折叠的光伏板 311, 其可以从中部被折叠 , 从而缩小整体装置的收纳尺寸。 [0031] 柔性反射面 320的上边缘通过挂杆 331由一对撑杆 332和 332'来支撑。 柔性反射面
320的下边缘可通过例如地钉 (未图示) 固定在地面上, 并位于光伏板 311的一 侧。 菲涅尔透镜 350固定在撑杆 332和 332'的中下部。
[0032] 作为一种优选的实施方式, 本实施例还包括一延伸方向与挂杆 331基本一致的 横杆 334, 横杆 334的竖向高度低于挂杆 331。 撑杆 332和 332'上还分别设置有基本 横向延伸的分支 3321和 3321', 横杆 334支撑在分支 3321和 3321'的端部。 柔性反射 面 320在横杆 334处被其弯折形成为折面。 进一步优选地, 分支在撑杆上的竖向 高度能够被调节, 或者, 分支的横向延伸长度能够被调节, 从而调整柔性反射 面被弯折的位置和角度。
[0033] 通过弯折柔性反射面, 本实施例装置能够获得更多的太阳能。 同时, 将柔性反 射面弯曲成折面, 有助于增加反射面的高度。 而对于本实施例而言, 高度越高 , 聚光能力就越强。 在其他实施方式中, 若采用单个撑杆的结构, 同样也可以 设置相应的分支和横杆。
[0034] 实施例 4
[0035] 依据本发明的便携式太阳能装置的另一种实施方式可参考图 5 , 包括光能利用 装置 410, 柔性反射面 420和 420', 挂杆 431和 431', 撑杆 432和 432'以及菲涅尔透 镜 450。
[0036] 本实施例中设置有两个柔性反射面 420和 420', 分别位于光能利用装置的相对的 两侧。 每个柔性反射面分别通过挂杆由一个撑杆支撑。
[0037] 本实施例中的光能利用装置 410除了光伏板 (未图示) 还包括聚光装置 412。 具 体地, 聚光装置 412为顶部开口较大而底部开口较小的锥形聚光漏斗, 其内壁为 反射面, 光伏板设置在聚光漏斗的底部。 柔性反射面的下边缘分别连接到聚光 漏斗的相应的一侧边缘。
[0038] 菲涅尔透镜 450竖直设置在光能利用装置 410的上方, 具体可采用向下散光的菲 涅尔透镜, 例如图 3所示的部分菲涅尔透镜。
[0039] 本实施例显示了一种简易地增加太阳能收集能力的方式。 在其他实施方式中, 还可增加热能利用装置 (如热能发电机、 热电转换装置等) 来进一步充分地利 用热能。 [0040]
[0041] 以上应用具体个例对本发明的原理及实施方式进行了阐述, 应该理解, 以上实 施方式只是用于帮助理解本发明, 而不应理解为对本发明的限制。 对于本领域 的一般技术人员, 依据本发明的思想, 可以对上述具体实施方式进行变化。
