Description

Technical Field

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

[0002] Photovoltaic brackets are brackets designed for placing, installing and fixing solar panels in photovoltaic power generation systems. Photovoltaic brackets are mainly composed of columns, main shafts, purlins and other structures. Among them, the solar panel is mounted on the horizontal main shaft through the purlins, and the columns are vertically set on the foundation or the ground. The main shaft is generally arranged in the north-south direction. The main shaft can rotate around its own rotation axis, thereby driving the purlins and solar panels installed on the main shaft to track the sunlight trajectory in the east-west direction, so that the solar panel can absorb as much solar radiation as possible.

[0003] With the increase of wear, the existing upper and lower split bearing structure will cause the gap to increase, which may easily lead to the jamming of the main shaft rotation, resulting in the reduction of the reliability of the tracking bracket.

[0004] Therefore, it is necessary to design a bearing device for a photovoltaic tracking bracket to solve the above problems. Utility Model Content
