Problems solved by technology

[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 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

Embodiment Construction

[0022] The present invention will be described in further detail below in combination with the accompanying drawings, and specific embodiments will be given.

[0023] Such as Figure 1-3 As shown, a solar dual-axis tracking system of the present invention can be installed on the support rod 1, and can automatically track the sun to achieve high utilization of solar energy, high safety performance, and is not affected by the environment . It includes a support rod 1, a solar panel 2, and a control system. The top of the support rod 1 is provided with an external tooth type slewing support bearing 3, and the inner ring of the slewing support bearing 3 is welded to the base 4. This connection method can withstand large overturning moment, one side of the base 4 is connected to the solar panel 2 through two hinges a5, the outer ring of the slewing support bearing 3 is connected to the azimuth tracking mechanism, and the other side of the base 4 is connected to the solar panel 2 ...

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.
