Disclosed in the present invention is a flexible photovoltaic tracking bracket, comprising: base structures fixed on the ground at intervals; beam structures mounted on the base structures; driving devices mounted on the beam structures and driving the beam structures to rotate about. Disclosed in the present invention is a flexible photovoltaic tracking bracket, comprising: base structures fixed on the ground at intervals; beam structures mounted on the base structures; driving devices mounted on the beam structures and driving the beam structures to rotate about. In the early stage of photovoltaic development, the brackets for installing photovoltaic modules were mainly fixed structures, with low cost and simple structure. With the continuous development of technology and the focus on power generation efficiency, tracking brackets have broad development. each of the transmission mechanismsincludes a shell and a transmission assembly, a receiving chamber is formed inside the shell, and the transmission assembly includes a first transmission member, a second transmission member, a third transmission member and a fourth transmission member located in. the flat single-axis tracking bracket structureis a plurality of columns supporting a full-length main beam, and the photovoltaic components are installed above the main beam and rotate around the axis with the center of the main beam as the axis. In this structural form, since the photovoltaic. A photovoltaic tracking bracket system, comprising a main shaft (1), a synchronous shaft (2), a driving source (3), and transmission mechanisms (4). The main shaft (1) has a cavity (10). These systems use electro-mechanical devices which orientate the angle implementation to PV plants and other solar applications.
