Sunlight angle automatic determination device

Abstract

A sunlight angle automatic determination device comprises a first photosensitive element and a second photosensitive element. The first photosensitive element and the second photosensitive element are fixed on a base. The base is connected with a rotating shaft. The rotating shaft is arranged on a support through a bearing. One end of the rotating shaft is connected with a flexible shaft. The first photosensitive element and the second photosensitive element form an axial symmetry figure corresponding to the rotating shaft. Leading wires of the first photosensitive element and the second photosensitive element are led out from the lower portion of the base and connected with an amplification and control system so as to control rotation of a motor. A plane of the support is fixedly installed with a plane of a reflecting mirror in a parallel mode, and the support can rotate along with the reflecting mirror. When the sunlight rotates an angle, the base rotates the angle. When the values of electric signals output by the two photosensitive elements are close, the sunlight perpendicularly irradiates the two photosensitive elements, reflection rays of the reflecting mirror return the predetermined direction again, and one-time sunlight angle automatic determination is completed. The process is continuously and repeatedly carried out along with movement of the sunlight. Therefore, the purpose of the sunlight angle automatic determination is achieved.

Description

technical field [0001] The invention relates to the field of solar energy applications, in particular to a device for automatically determining the angle of sunlight. Background technique [0002] For a long time, the world's energy has mainly relied on fossil fuels such as petroleum and coal. As a one-time non-renewable resource, these minerals have limited reserves, and when burned, a large amount of carbon dioxide is produced, causing the earth's temperature to rise and the ecological environment to deteriorate. According to the forecast of the International Energy Agency, mankind is facing the serious threat of fossil fuel depletion. This global energy crisis has forced governments to invest a lot of manpower and financial resources in research and development of new energy sources, such as solar energy. Solar energy is an inexhaustible clean energy, and the utilization of solar energy has very broad application prospects. [0003] In the process of utilizing solar ene...
