Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic installation, in particular to a fixing bracket for photovoltaic grid-connected block power generation construction. Background Technique

[0002] Photovoltaic power generation systems can be divided into off-grid photovoltaic power generation systems and grid-connected photovoltaic power generation systems. The investment in grid-connected photovoltaic power generation systems is 25% less than that of off-grid photovoltaic power generation systems. Connecting the photovoltaic power generation system to the large power grid in the form of a microgrid and operating in parallel with the large power grid to support each other is an important technical way to improve the scale of photovoltaic power generation. The grid-connected operation of photovoltaic power generation systems is also the main direction of future technological development. Through grid connection, the scope and flexibility of solar energy use can be expanded.

[0003] The existing photovoltaic grid-connected block power generation devices are relatively concentrated. When it is necessary to install the photovoltaic grid-connected system in different regions in blocks according to actual needs, or when installing the photovoltaic grid-connected system in some rugged terrains, the existing structures cannot adapt to the terrain, resulting in a large amount of work and low construction efficiency. Moreover, either the support structure of the existing photovoltaic grid-connected block power generation device is relatively complex. For example, the patent document with the publication number CN217957010U discloses an adjustable bracket for distributed photovoltaic panels, including a bottom plate, an assembled support member, an adjustment component, and a power generation panel placement shell. The assembled support member includes a bottom support frame, an intermediate support frame, and a top support frame, and the three are sequentially combined and sleeved together. The adjustment component is installed on the assembled support member, and the photovoltaic panel is supported and adjusted by a rotating motor, a rotating plate, an adjustment screw, and an adjustment arm. The support is a tower structure and is very complex, and it is also necessary to drive the photovoltaic panel by a motor, consuming a lot of energy. Or the support stability is relatively poor. For example, in the patent document with the publication number CN113489444B, although the angle of the photovoltaic panel can be adjusted, the photovoltaic panel is only installed on the top of a small column and is connected to the small column at a single point, so the support is relatively thin and the stability is poor.
