波形瓦聚光装置Corrugated tile concentrating device

所属技术领域Technical field

本实用新型涉及太阳能发电领域，具体是一种波形瓦聚光装置。The utility model relates to the field of solar power generation, in particular to a corrugated tile light concentrating device.

背景技术Background technique

太阳能光伏发电技术为未来解决能源问题提供广阔前景，但存在发电成本高，光电转换效率不高的问题。因此，降低成本和提高效率成为太阳能发电大规模应用的关键，太阳能聚光是降低太阳能光伏发电成本的有效途径。太阳光聚光一般采用菲涅耳透镜、槽形反射、抛物面反射等方式，但需安装太阳光跟踪器才能达到聚光效果。采用太阳光跟踪器，成本高，可靠性差，无法与建筑一体化相结合，不便于安装。取消太阳光跟踪器是目前太阳能发电领域迫切需要解决的技术问题。Solar photovoltaic power generation technology provides broad prospects for solving energy problems in the future, but there are problems of high power generation costs and low photoelectric conversion efficiency. Therefore, cost reduction and efficiency improvement have become the key to the large-scale application of solar power generation, and solar concentration is an effective way to reduce the cost of solar photovoltaic power generation. Concentrating sunlight generally adopts Fresnel lens, trough reflection, parabolic reflection and other methods, but it is necessary to install a solar tracker to achieve the concentrating effect. The use of solar trackers has high cost and poor reliability, and cannot be integrated with buildings, which is not easy to install. Canceling the solar tracker is an urgent technical problem in the field of solar power generation.

为了取消太阳光跟踪器，目前有采用球聚焦的方式，如专利申请号为20610076928.3公开的一种“太阳光集聚器”，专利号ZL200620005067.5公开的一种“万向聚光镜”，专利号ZL200820185105.9公开的一种“全方向太阳光聚光装置”。这些聚光方式能聚集太阳光，聚焦比高，但由于体积、重量较大，不方便安装，在太阳能发电领域无法大规模实用推广。In order to cancel the solar tracker, there is currently a spherical focusing method, such as a "sunlight concentrator" disclosed in patent application No. 20610076928.3, a "universal concentrator" disclosed in patent No. ZL200620005067.5, and patent No. ZL200820185105 .9 discloses a "omnidirectional sunlight concentrating device". These concentrating methods can gather sunlight and have a high focusing ratio, but due to their large size and weight, they are inconvenient to install and cannot be widely used in the field of solar power generation.

综上所述，现有聚光方式都能把太阳光聚焦于一点，聚焦点随着太阳光的移动而移动，普遍采用成本较高、性能不稳定、安装维护不便的太阳光跟踪器，不易与建筑相结合。To sum up, the existing concentrating methods can focus sunlight on one point, and the focus point moves with the movement of sunlight. It is not easy to use solar trackers with high cost, unstable performance, and inconvenient installation and maintenance. Combined with architecture.
