[0074] It should be noted that, in the present embodiment, in order to increase the tracking effect of the photovoltaic tracking support driving the photovoltaic panel to perform photovoltaic tracking, and improve the photovoltaic power generation efficiency, a third driving structure is provided on the photovoltaic tracking support, the third driving structure comprises a third driving part, a third fixed member and a third movable member, the axis of the third driving part is perpendicular to the axis of the hinge part 11, the third movable member is connected with the support member 1, and the third fixed member is connected with the external support structure, under the action of the third driving part, the support member 1 rotates relative to the external support structure.

[0076] As a second aspect of the present embodiment, a photovoltaic tracking system is disclosed, comprising the photovoltaic tracking support as described above.

[0077] The embodiment has the advantages of improving the power generation efficiency of the photovoltaic tracking system, reducing the energy consumption of the photovoltaic tracking support, and enhancing the stability of the photovoltaic tracking support connecting the photovoltaic panel.

[0078] Firstly, the photovoltaic tracking support provided in the embodiment drives the first carrier 2 and the second carrier 3 to rotate around the first axis relative to the support 1 through the first driving part 41, so as to drive the photovoltaic panel to perform the photovoltaic tracking task. When there is no sun or the weather is bad, the first driving part 41 and the second driving part 51 are started at the same time. The first driving part 41 drives the first carrier 2 and the second carrier 3 to rotate, so that the first carrier 2 is folded to be close to the external support structure. The second driving part 51 drives the second carrier 3 to rotate around the axis of the hinge part 11 relative to the first carrier 2, so that the second carrier 3 is folded to be close to the external support structure, thereby realizing the folding of the photovoltaic panel, reducing the windward area of the photovoltaic panel, and increasing the service life of the photovoltaic tracking support.

[0079] Secondly, when the photovoltaic tracking support provided in the embodiment drives the photovoltaic panel to fold, the first driving part 41 and the second driving part 51 work at the same time, driving the first carrier 2 and the second carrier 3 to unfold upward around the axis of the hinge part 11. When the light-receiving surfaces of the two photovoltaic panels are in the same plane, since the first fixed part 42 of the second driving part 51 is connected with the second carrier 3, and the second movable part 53 is connected with the first carrier 2, only the first driving part 41 needs to be driven to drive the two photovoltaic panels to perform the photovoltaic tracking work at the same time. This avoids the situation that the two photovoltaic panels block each other or the light-receiving surfaces are not in the same plane, so that the light-receiving surfaces of the two photovoltaic panels are always perpendicular to the light, thereby improving the power generation efficiency of the photovoltaic tracking system.

[0080] Thirdly, the first carrier 2 of the embodiment connects the photovoltaic panel through the first outer end face 22, and the second carrier 3 connects the carrier through the second outer end face 32. Both the first outer end and the second outer end are in the shape of Ω, which can expand the range of connecting the photovoltaic panel and make the center of gravity of the photovoltaic panel closer to the first carrier 2 or the second carrier 3. In the traditional tracking photovoltaic device or foldable photovoltaic tracking device, the connection mode of the photovoltaic panel is usually that the side edge of the photovoltaic panel is connected to the corresponding support. Therefore, compared with the traditional connection mode, the connection mode of the photovoltaic tracking support connecting the photovoltaic panel in the embodiment significantly shortens the distance between the photovoltaic tracking support and the center of gravity of the photovoltaic panel, thereby enhancing the stability of the photovoltaic panel connection.
