Description

Background At the moment that energy structure transformation and energy conservation and emission reduction demands are urgent, solar energy is used as clean and renewable energy, and is widely applied to the field of regional heating. The trough type solar heat collection system has the advantages of relatively simple structure, high heat collection efficiency and the like, and becomes one of important technical schemes for regional heating. However, in the practical application process of the conventional trough-type solar regional heating system, a plurality of technical bottlenecks still exist, and further improvement of heat collection efficiency and operation stability of the conventional trough-type solar regional heating system is restricted. Firstly, the mirror plate in the traditional system adopts a mode of integral fixing or single driving positioning, and can only carry out rough angle adjustment according to the approximate position of the sun, so that the accurate tracking of the real-time position of the sun can not be realized. Secondly, the installation position of the heat collecting tube in the prior system is usually fixed, and the problem that the reflection light spot of the mirror plate can deviate along with the change of the position of the sun is not considered. When the reflection facula position of the mirror plate changes, the fixed heat collecting pipe can not adjust the position of the heat collecting pipe in time to receive facula with the largest area, so that the heat collecting efficiency of the system is further reduced, and the requirement of regional heating on stable heat energy output is difficult to meet. Furthermore, the mirror panels of the trough solar system are exposed to outdoor environment for a long time, dust, fallen leaves, bird droppings and other impurities are easy to adhere to the mirror panels, and the reflectivity of the mirror panels is obviously reduced by the impurities, so that the heat collection efficiency is continuously reduced.
