本实施例提供的太阳能聚集装置，利用聚光器110将太阳光反射进入到光导管120中，太阳光进入光导管120后沿着光导管120传播，至少两根光导管120的端部汇集形成太阳能输出部，太阳光加热位于光导管120中的空气并将热量从太阳能输出部输出至待利用太阳能的设备上。通过设置至少两个聚光器110，且每个聚光器110将太阳光导入到光导管120中，太阳光在光导管120中传播，不易被光导管120吸收，太阳光的能量不易被削弱， 大量的太阳管通过光导管120后聚集在一起，热量高，太阳能的利用效率高。
需要说明的是，至少两个太阳能聚集单元100的数量按需设置，根据所需太阳能的多少以及使用环境等因数综合考虑确定，在此不进行具体限定。
应当理解，光导管120的形状以及大小按需设置，可选的，光导管120设置为圆柱形管，结构规整，便于加工，且光导管120的内壁为圆柱面，不易阻挡光线，便于光线的传播。光导管120的内径按需设置，在此不进行具体限定。
请参阅图4，可选的，聚光器110为圆锥状的聚光板，聚光板的内周面设置为反光面，太阳光照射进入到聚光器110后，通过反光面的反光作用，将太阳光反射进入到光导管120中。聚光板具备第一端口以及第二端口，聚光板沿其中轴线方向的内径由第一端口向第二端口逐渐减小，第二端口安装在光导管120上。聚光器110安装完成后，第一端口朝上，朝向太阳所在方向，太阳光从第一端口照射进入，并照射在反光面上，并由反光面反射进入到第二端口，从第二端口入射到光导管120中。
可选的，聚光器110设置为反光碗。反光碗的结构简单，制造成本低，采用抛物线曲面设计，能更有效的降低光损，聚光效果好。
请参阅图4，可选的，聚光器110具备安装部，安装部为安装管，安装管可以是圆柱形管，与圆柱形的光导管120配合更好。安装部位于反光碗的第二端口处，安装部的内径与第二端口的内径相等，安装部的内管壁和反光碗的反射面平滑连接，没有突出的部分，便于光线的传播。
可选的，安装部的外周面设置有外螺纹，光导管120的内管壁设置有内螺纹，安装部和光导管120通过螺纹连接。
应当理解，在其他实施例中，聚光器110和光导管120可以通过卡扣结构连接或者螺栓固定连接，在此不进行一一列举。
请参阅图3，本实施例中，光导管120包括内层反射层121、中间耐热层122以及外层加固层123，内层反射层121位于中间耐热层122的内管壁上，外层加固层123套设在中间耐热层122外。可选的，内层反射层121设置为铜镀铬层，中间耐热层122设置为石棉层或者陶瓷纤维层，外层加固层123设置为金属管。可选的，金属管可以是网状结构。通过将光导管120的内关闭设置为镀铜铬层，光的反射效果好，从聚光器110传播进入的太阳光大部分被镀铜铬层反射，不易被吸收，降低光损，提高太阳光的利用效率。
本实施例中可选的，太阳能聚集装置还包括安装件200以及能量聚集主管300。安装件200为板状结构，安装件200可以是矩形板、圆形板或者其他形状的板。在安装件200上设置有贯穿安装件200的至少两个安装孔210，安装孔210为圆锥形孔，与反光碗的尺 寸相匹配，将反光碗置于对应的圆锥形孔内，实现反光碗的固定。显然，反光碗与安装件200之间可以通过胶水等方式固定连接。
可选的，相邻的安装孔210的上边缘相接，也即，将反光碗安装在安装孔210内后，相邻的两个反光碗的部分边缘接触。这样，在安装件200上有限的面积上可以设置更多的安装孔210，进而安装更多的反光碗，提高太阳光的利用效率。
可选的，聚光器110呈圆周分部。对应的，至少两个光导管120呈圆周分布，且光导管120远离聚光器110的端部朝向圆周的中部延伸。至少两个光导管120远离聚光器110的端部朝向中部汇集，便于将至少两个光导管120与能量聚集主管300连接，整体结构更加紧凑。
需要说明的是，能量聚集主管300可以是圆柱形管，能量聚集主管300的尺寸和大小按需设置即可。
可选的，太阳能聚集装置还包括透明盖板400，透明盖板400盖设在聚光器110的第一端口，防止灰尘或者雨水进入。透明盖板400可以是玻璃板。
实际应用过程中，可以将安装件200置于屋顶，聚光器110位于屋顶，充分接收太阳光照，提高太阳能的利用率。显然，可以将安装件200安放在上坡、荒地或者水面上，本实施例中不进行一一列举。
