Embodiment Construction

[0045] Such as figure 1 , 2, 3, 4 shows a solar photovoltaic power generation device, mainly including light superimposed reflector 1, heat dissipation device 3, solar tracking device 4, cement base 6 and support frame 2; the light superimposed reflector 1 is mainly composed of The solar wafer 11 and the light superimposing reflection device 12 are composed; the light superimposing reflection device 12 is formed by coaxially stacking three layers of light superimposing mirrors 121; the light superimposing mirror 121 is composed of 8 mirror units 1211 Continuously fixed; the light superimposed mirror 121 follows the stacking sequence from bottom to top, the angle β between the mirror unit 1211 and the center line of the light superimposed mirror gradually increases, and the area of ​​the mirror unit gradually decreases The reflector unit is an oblique plane with an oblique line rotating around the central axis of the ring-shaped light stacking mirror by an angle of α, and satisfie...

Abstract

The invention provides a 'solar photovoltaic power generation device', which adopts an optical superposition method, three groups of reflecting mirrors (ordinary plate glass mirrors) are used for causing the sunlight to be fully superposed on a silicon chip on different levels, a 24-hour computer is matched to automatically track the sun, namely, longitude tracking, latitude tracking and earth revolution angle tracking, therefore, the effect that the power generation capacity of an ordinary solar chip is improved by more than 6.6 times is obtained. The power generation efficiency of the current silicon chip is 16 percent, while the power generation efficiency of the invention reaches more than 105.6 percent. The invention utilizes the equilibrium principle and puts the point of strength on the overcoming of the damping of a bracket instead of the self weight of the bracket, therefore, a gear is not easy to be damaged and power consumption is saved. By repeatedly testing, power consumption needed by the tracking device is only 3 percent to 5 percent of the self power generation (the power consumption includes electric energy consumed during the heat dissipation of the chip).

Description

Technical field [0001] The present invention mainly relates to a solar power generation device, in particular to a large-scale photovoltaic power generation device. Background technique [0002] At present, in the photovoltaic power generation industry, the utilization rate of solar wafers is generally only 16%-18%. At the same time, large-scale solar tracking mechanisms have the following worldwide technical problems: gearboxes are often damaged, high maintenance costs, and normal power generation is impossible. The reason is that its intermittent tracking technology is flawed. The angular acceleration is too large when starting, especially when stopping, causing the gearbox to be destroyed in a short period of time, which eventually leads to failure. Summary of the invention [0003] The purpose of the present invention is to provide a solar power generation device that can generate high-efficiency power generation, have no gear damage when tracking the sun, save power consump...
