Photovoltaic panel tracking device with high tracking precision

Abstract

A photovoltaic panel tracking device with high tracking precision comprises a mounting angle adjusting device, worm gear reducers, a first motor, a rotation shaft, a shaft and a photovoltaic panel. The first motor is fixedly mounted on the first worm gear reducer, one end of the rotation shaft is connected with an output shaft of the first worm gear reducer through a coupler and penetrates through a bearing block, the middle of the shaft is mounted on the rotation shaft, two ends of the shaft are mounted on the bearing block, the bottom of the photovoltaic panel is fixed on the bearing block, a second motor is fixedly mounted on the second worm gear reducer, an output shaft of the second worm gear reducer is connected with a first synchronizing wheel, a lead screw penetrates through an extension platform with a threaded hole, a second synchronizing wheel is mounted above the threaded hole of the extension platform, a nut screwed with the lead screw is arranged in the second synchronizing wheel, the top end of the lead screw is hinged to a sliding shaft, the sliding shaft is mounted in sliding rails on two sides of a sliding rail device, and the top end of the sliding rail device is fixedly mounted at the bottom end of the photovoltaic panel. The photovoltaic panel tracking device can realize real-time tracking in a solar hour angle direction and a solar declination angle direction, and is high in tracking accuracy, stable in mechanism operation and simple in structure.

Description

technical field [0001] The invention relates to the technical field of a tracking system, in particular to a photovoltaic panel tracking device with high tracking accuracy. Background technique [0002] The development and utilization of solar energy has broad prospects, and the comprehensive and efficient utilization of solar energy is the goal pursued by people engaged in the field of solar energy development. The tracking efficiency of the solar tracking method in the one-dimensional direction is poor. The traditional photovoltaic dual-axis tracking mechanism realizes the track tracking of the solar energy through two-dimensional tracking in the latitude and longitude directions. Although this method can ensure the tracking accuracy, it has complex structures, high failure rates, The disadvantages such as high cost are difficult to be applied in real life. The trajectory of the sun can be regarded as the change of the solar hour angle caused by the earth's rotation durin...

AI Technical Summary

Problems solved by technology

The tracking efficiency of the tracking device by tracking the solar hour angle and declination angle is high, but due to the small change range of the declination angle and the problem of installation angle of the system, in the prior art, for the simultaneous tracking in these two directions The system design cannot be well coordinated

As a result, the tracking accuracy of some devices is not enough, and the structure of some devices with high tracking accuracy is too complicated
