Double-shaft sun tracking platform

Abstract

The invention discloses a double-shaft sun tracking platform, which comprises a base, a sunlight receiver and a double-shaft rotary device. The double-shaft sun tracking platform is characterized in that: the double-shaft rotary device comprises an oblique rotary shaft and a horizontal rotary shaft; the oblique rotary shaft is connected with the sunlight receiver and obliquely arranged at the upper end of a receiver bracket, and a motor drives the oblique rotary shaft to rotate and drives the sunlight receiver to rotate around the oblique rotary shaft so as to finish tracking the sun on a certain day; the horizontal rotary shaft is connected with the base and horizontally arranged at the lower end of the receiver bracket, and the receiver bracket can rotate around the horizontal rotary shaft and indirectly drives the sunlight receiver to rotate around the horizontal rotary shaft so as to finish tracking the sun in change of four seasons in a year; and the rotary drive of the receiver bracket around the horizontal rotary shaft is implemented by a planar four-bar mechanism.

Description

technical field [0001] The invention relates to solar energy utilization facility technology, specifically a dual-axis sun tracking platform, which aims to make the solar receiver always face the sun directly through the coordinated rotation of the two axes, and track the sun's daily sunrise and sunset and track changes throughout the year. In order to make full use of solar energy. Background technique [0002] Energy is the driving force of social and economic development. However, a large amount of fossil energy consumption is increasingly showing unsustainability. Solar energy, a renewable energy source, is clean, pollution-free, and renewable, and meets the requirements of sustainable development. In the field of solar energy utilization facilities, people continue to study sun-tracking technology, and many sun-tracking devices have emerged as the times require, and a number of patents for sun-tracking technology have also been authorized. For example, although the i...

AI Technical Summary

Problems solved by technology

The invention patent "sun tracking device (publication number CN101173826A)" adopts the mechanism of external rotation angle and internal rotation angle, which has better rigidity, but the equipment space is also large

In addition, the hybrid dual-axis automatic solar tracking device researched by Wang Shangwen et al. The high-degree rotating shaft adopts a vertical shaft structure, and the rigidity is relatively poor

The automatic sun tracking system studied by Liu Wei et al. (Liu Wei et al., Research and Design of Automatic Sun Tracking System, Hydropower Energy Science, Vol.27, No.2, 2009) adopts horizontal rotation axis of 0-180 degrees for fixed day tracking. Rotating shaft, poor rigidity, and equipment takes up a lot of space

In short, all kinds of sun tracking devices have different application occasions or methods at present. Although they can meet the requirements of the rotation range of tracking the sun, they have disadvantages such as complicated mechanical structure, poor equipment rigidity, not compact overall structure, and not simple enough control.
