Description

Brackets for fixing photovoltaic modules

technical field

The utility model relates to a bracket for fixedly installing photovoltaic modules.

Background technique

In photovoltaic power generation systems, brackets that can manually adjust the installation inclination of components and single-axis tracking brackets are two commonly used photovoltaic array brackets. Since this type of bracket needs to be rotated to adjust the installation angle of photovoltaic modules, rectangular tubes are often used as the main beam. To carry photovoltaic modules, generally the main beam is supported on the ground by support rods. The photovoltaic module is fixed on the main beam by a special bracket.

The inventor of the utility model once disclosed a "photovoltaic module fixing bracket with saddle-shaped clip pad" in the patent document "CN202816974U", wherein the purlin is a rectangular tube, square tube or C-shaped steel structure, and there are several holes on the purlin. The waist hole connected to the main beam and the piercing hole connected to the photovoltaic module. The purlin 6 is connected to the photovoltaic module through the saddle-shaped clip 7 . The saddle-shaped clip has a flat part, an upwardly bent rib formed by bending the two lateral edges of the flat part upward, and a downwardly bent rib formed by bending down the longitudinal two ends of the flat part. The middle part of the rib has an opening for the purlin to pass through. The connection between the photovoltaic module and the purlin adopts a saddle-shaped clamp pad, so that the photovoltaic modules supported on both sides will not fall off when the width of the purlin is narrow. This structure not only ensures the firm support of the purlin to the photovoltaic module, but also saves the amount of steel.

In the further practice of the inventor of the utility model, it is found that it is necessary to provide another structure of the bracket.
