Description
技术领域
本发明涉及太阳能应用技术，特别是涉及一种抛物镜聚光太阳能装置。
背景技术
聚光太阳能可提高太阳能利用效率，如聚光光伏使用硅聚光电池可以减少30倍左右硅片使用量，使用砷化镓太阳能电池，转换效率可达40％以上，用液体冷却可电热联供，光热应用可产生热蒸汽，应用广泛。但聚光应用却受到多种因素的制约，如太阳光跟踪机构成本，跟踪精度和稳定性，聚光镜的几何精度、效率、强度、寿命、成本等都制约着聚光太阳能的广泛应用，从而导致现在相关应用产品极少。
发明内容
针对上述技术存在的缺陷，本发明提供了一种抛物镜聚光太阳能装置，该装置具有跟踪精度高、成本低、使用寿命长、反射率高、易清洁等优点。
为实现上述目的，本发明的技术方案为：一种抛物镜聚光太阳能装置，它由抛物反光镜(12)、支撑架(7)、可绕转轴(8)、推杆(9)、转盘减速机(11)、聚光光伏组件(13)组成，其特征为：反光镜(12)固定在支撑架(7)上，可绕转轴(8)转动，推杆(9)的伸缩调整反光镜与太阳仰角一致，反光镜(12)、支撑架(7)、推杆(9)一起都安装在转盘减速机(11)上，可绕支撑腿(10)作水平旋转，以调节反光镜与太阳方位角一致，当太阳照到反光镜(12)上时，光线被反射到聚光光伏组件(13)上，产生电力，把聚光光伏组件换成热管，则可光热利用。
所述的反光镜(12)由低铁高透弯强化镀银镜玻璃(1)、背板弯强化玻璃(2)、夹胶抛物镜(3)、加强筋(4)和弧度调节拉杆(5)、卡槽嵌板(6)组成，低铁高透弯强化镀银镜玻璃(1)与背板弯强化玻璃(2)制成夹胶抛物镜(3)。
所述的反光镜(12)的背板上有加强筋(4)和弧度调节拉杆(5)，弧度边沿设有抛物线卡槽嵌板(6)。
本发明的有益效果：本装置具有寿命长，反射率高，易清洁等特点，可精准调节抛物镜弧度，使得抛物曲面吻合度达0.5mm以内，达到优良的聚光性能，聚光倍比可达30-150倍，聚焦光斑均匀，可用聚光晶硅电池组件及砷化镓太阳能电池组件；组件散热采用铝翅片风冷或导热油和水冷，还可得到一定温度的热水。
附图说明
图1为本发明的结构示意图。
图2为抛物镜背板示意图。
图3为抛物镜结构示意图。
具体实施方式
现结合附图对本发明做进一步说明。
抛物镜结构见图2，采用低铁高透弯强化镀银镜玻璃(1)，镀银镜面是浮法玻璃的氮气面，平整度高，玻璃反射率在93％以上，与背板弯强化玻璃或弧形玻璃钢FRP、弧形金属板(2)，制成夹胶抛物镜(3)。玻璃经过强化后可做227克钢球1米高落球测验，强度高，抗冰雹及砂石能力强。且银层在夹层中，不受水、气、硫等的影响，具有寿命长，反射率高，易清洁等特点。
把反光镜(12)固定在支撑架(7)上，可绕转轴(8)转动，推杆(9)的伸缩调整反光镜与太阳仰角一致，反光镜(12)、支撑架(7)、推杆(9)一起都安装在转盘减速机(11)上，可绕支撑腿(10)作水平旋转，以调节反光镜与太阳方位角一致，当太阳照到反光镜(12)上时，光线被反射到聚光光伏组件(13)上，产生电力，把聚光光伏组件换成热管，则可光热利用。
