Three-dimensional solar tracking system with only one motor and control method thereof

Abstract

The invention relates to a three-dimensional solar tracking system with only one motor and a control method thereof. The system comprises a controller, the motor, at least one electromagnet engaging and disengaging device, a systematic declination angle regulating mechanism and at least two solar tracking devices, wherein the controller controls the motor to drive an azimuth gear, a sprocket wheel or a worm wheel on any azimuth rotating shaft in the solar tracking system, or a gear, a chain or a worm respectively connected with the azimuth gear, the sprocket wheel or the worm wheel directly, indirectly or via a retarding mechanism, and the electromagnet engaging and disengaging device is utilized to enable each solar tracking device to perform three-dimensional solar tracking motion simultaneously along with solar azimuth, height and declination.

Description

technical field [0001] The invention belongs to the field of clean energy and photoelectric conversion device manufacturing, and in particular relates to a three-dimensional sun-tracking system and a control method thereof requiring only one motor. Background technique [0002] Solar energy is a huge natural energy that can be used indefinitely by human beings, and as a clean energy without any pollution, it has attracted more and more attention and great interest from all over the world. [0003] Humans have a long history of using solar energy, such as using steel four-sided mirrors to focus sunlight to ignite fires, using solar energy to dry agricultural and sideline products, and so on. So far, the utilization of solar energy has become increasingly widespread, including solar thermal utilization, photovoltaic utilization of solar energy and photochemical utilization of solar energy. [0004] However, due to technical problems, the price of photovoltaic power generation...
