A solar panel automatic tracking device

Abstract

The invention discloses a solar cell panel automatic tracking device. The solar cell panel automatic tracking device comprises a fixed support (1), a fixed platform (2) and a supporting platform (3). The fixed platform (2) is installed in the middle of the fixed support (1), the supporting platform (3) is installed on the fixed platform (2), and a universal joint (4) is connected to the supporting platform (3). A cell panel tray (5) is installed on the supporting platform (3) through the universal joint (4), and four hinges are installed on the reverse side of the cell panel tray (5) and are respectively installed on four top points of a square of which the center is the gravity center of the solar cell panel tray (5). Guide wheels (7), tension wheels (8) and stepping motors (9) are installed on the upper surface and the lower surface of the fixed support (2) respectively. The automatic tracking device is high in flexibility and tracking accuracy, wide in tracking range and high in effective generating capacity, can achieve omnibearing solar tracking, can be applied to large solar photovoltaic power stations, and has good economic benefits and environmental effects.

Description

technical field [0001] The invention relates to a solar energy device, in particular to an automatic tracking device for solar battery panels. Background technique [0002] As the world's energy is decreasing day by day, renewable energy power generation technology has developed rapidly, and solar power generation has attracted more and more attention due to its unique advantages. How to improve the effective power generation of solar photovoltaic power generation has always been the goal pursued by people. The utilization rate of solar energy mainly depends on the conversion efficiency and receiving efficiency of the battery. The conversion efficiency is determined by the performance of the battery itself, which depends on the continuous renewal of solar cells; while the reception efficiency can be improved through existing technologies. Existing solar panel tracking devices mainly include single-axis and two-axis. In recent years, many forms of solar tracking devices and...

AI Technical Summary

Problems solved by technology

[0003] These tracking devices mainly adopt a two-axis tracking method, which improves the receiving efficiency of the battery panel to a certain extent, but has the following disadvantages: 1. Using gear transmission or turbine transmission, the reliability of the entire device is low and the maintenance cost is high; 2. The shaft in the device has to rotate and bear the weight of the entire battery panel, so the design requirements for the shaft are relatively strict and the cost is high; 3. The entire shaft is driven by a motor to rotate, so more power is consumed
