In the face of the threat of air pollution and the greenhouse effect,the development and efficient use of green energy is very important. A new and efficient intelligent solar power supply equipment is designed. By skillfully arranging the photosensitive film on the solar panel,a servo automatic detection system is designed to measure the azimuth of the sun's light. This make it to automatically track the position of the sun's light and the sun shine directly on the solar panel. To realize the integration design of measurement,tracking driving energy efficient acquisition. Design a new bottom rotating structure with the equipment characteristics. The energy saving control method is designed,and the equipment is subjected to wind analysis. On this basis,topology optimization analysis is carried out on the side supporting plate based on variable density method,which makes the equipment lightweight and effectively reduces the lateral wind force,side plate weight reduction is 28. 2 %,overall lateral wind resistance is reduced by 26. 36 %. The strength analysis shows that the deformation of the side plate is small and meets the requirement of strength. Research shows that the structure of the equipment is ingenious,the expansibility is strong,and the solar panel array is easy to be set. It has a broad application prospect.
