Abstract
The application relates to a device and a method for detecting whether the focusing of a tower type solar power generation system is accurate, which comprises a first detection body and a second detection body, the first detection body is provided with a first plane, a second plane and a third plane which can both reflect light and allow light to pass through, the first plane, the second plane and the third plane are arranged at 90 degrees and intersect at a point O; the second detection body is provided with a fourth plane which can both reflect light and allow light to pass through, and the fourth plane is arranged on the front side of the first detection body far away from the point O. The application fully utilizes the reflection and light transmission principle of light, the irradiation direction of the sunlight is fed back through the image of the sun, and whether the image of the sun is aligned with the collector of the tower type solar power generation system can directly judge whether the focusing of the heliostat is accurate, the detection is very intuitive and convenient, the detection time is greatly saved, and the efficiency of rectification is improved; and the application has the advantages of simple structure, low cost and convenient large-scale application.
