Technical Field

[0001] The utility model relates to the technical field of photovoltaic tracking brackets, in particular to a transmission system of a photovoltaic tracking bracket. Background Art

[0002] In photovoltaic power generation systems, the flat single-axis tracking bracket is one of the most commonly used photovoltaic array brackets. Since the bracket can track the changes in the solar azimuth angle during the day, the total annual power generation of photovoltaic modules using flat single-axis tracking brackets is 15%-25% higher than the total annual power generation of photovoltaic modules using the optimal fixed-tilt bracket.

[0003] The existing patent (application number: CN202020672094.8) discloses a photovoltaic tracking bracket and its transmission device. The photovoltaic tracking bracket includes a column and a main beam. The main beam is rotatably supported on the column, and the main beam supports the photovoltaic assembly. The transmission device includes a composite sprocket set and a composite sprocket wheel set. The composite sprocket set has multiple sprockets, and the multiple sprockets are coaxially arranged and staggered with each other. The composite sprocket wheel set has multiple sprocket wheels, and the multiple sprocket wheels are coaxially arranged, and correspond one to one with the multiple sprockets and mesh with each other for transmission. One of the composite sprocket set and the composite sprocket wheel set is rotatably arranged on the column, and the other is connected to the main beam.

[0004] The above patent has the following defects: the photovoltaic tracking bracket of the patent can only rotate left and right, and the photovoltaic tracking bracket cannot rotate horizontally, so that during the installation process of the patent, when the left and right rotation direction of the photovoltaic tracking bracket is not just tracking the change of the solar azimuth angle, it needs to be reinstalled, which makes its installation more troublesome. In addition, the patent uses a sprocket and a sprocket combination to drive the photovoltaic tracking bracket to track the rotation. When the sprocket and the sprocket mesh and rotate, both are prone to wear, which easily affects the overall service life. Therefore, the utility model provides a transmission system for a photovoltaic tracking bracket. Utility Model Content
