Three-dimensional solar energy tracking collection system based on folding lighting mirror surface

Abstract

The invention relates to a solar tracking and collecting system with a foldable mirror surface, which mainly includes three parts: a main column, a rotatable beam and a foldable daylighting mirror surface. The main column plays the role of carrying the whole system structure and collecting solar energy. The rotating beam on the main column can rotate around the main column in the horizontal plane, and can track the azimuth of the sun through motor control. The foldable daylighting mirrors are located on both sides of the rotating beam and can rotate around the rotating beam through the pitch beam below it. Its rotation can be realized by controlling the rotation of the motor to track the altitude angle of the sun. By tracking the altitude and azimuth of the sun, the lighting mirror can realize accurate positioning of the sun. The present invention is provided with anti-vibration mechanism. The bottom of the main column is a sliding platform structure, which can effectively buffer when the longitudinal wave of the earthquake strikes. There are stay wires around the main column, one end of which is connected to the main column, and a wire retracting mechanism is provided at the bottom. When an earthquake strikes, the mechanism can provide a certain space for the main column to move up and down by setting out the wires.

Description

technical field [0001] The invention relates to a solar tracking and collecting system, in particular to a three-dimensional solar tracking and collecting system based on a foldable daylighting mirror and realizing solar energy collection through multiple reflections. Background technique [0002] With the continuous development of social economy, the demand for energy in various countries is increasing, but the traditional energy represented by oil and coal is facing many problems such as resource depletion and environmental pollution. It has become the consensus of all countries in the world to vigorously develop clean and efficient new energy. The research and utilization of solar energy has been going on for some time, but there are more or less certain problems. [0003] Traditional solar energy collection systems are divided into three categories: tower type, dish type and trough type. Among them, the traditional tower-type solar energy collection system mainly has p...

In addition, longer mirrors and heat collectors will also have a negative impact on the wind resistance of the system

[0006] As mentioned above, the development and utilization of solar energy is becoming more and more important in today's increasingly prominent energy and environmental issues. However, the current traditional solar energy collection systems have their imperfections and urgently need to be improved.
