Solar energy dual-axis tracking system

Abstract

The invention discloses a solar energy dual-axis tracking system which comprises a support rod, a solar cell panel and a control system. The top of the support rod is provided with an external gear type slewing bearing. An inner ring of the slewing bearing is connected to the base, and one side of the base is connected to the solar cell panel via two hinges a. An outer ring of the slewing bearingis connected to an azimuth angle tracking mechanism. An elevation angle tracking mechanism is arranged between the other side of the base and the solar cell panel. The control system is electrically connected to the azimuth angle tracking mechanism and the elevation angle tracking mechanism. According to the system, the efficient use of solar energy can be achieved, and the system has good safetyperformance and is not affected by the environment.

Description

technical field [0001] The invention belongs to the technical field of energy utilization, and in particular relates to a solar energy dual-axis tracking system. Background technique [0002] At present, the known automatic sun tracking system devices generally have two forms, one is fixed, installed on a support pole, such as a solar panel with a 45-degree inclination fixed on a street lamp, this form can prevent obstacles from blocking solar energy. The sunlight received by the solar panel, but the utilization rate of the sunlight is relatively low, it cannot be fully absorbed, and most of it is wasted. [0003] The other is the single-axis type, which is installed on the ground. This type is suitable for a large area of ​​open land without obstacles. It is not suitable for street lights in cities, although the utilization rate of the sun is high. , but subject to environmental conditions, and the safety factor of the device fixed on the ground is not high.
