Description

Technical Field

[0001] The utility model relates to the photovoltaic field, in particular to a ground supporting device for a combiner box. Background Art

[0002] In the legless aluminum alloy ground bracket system currently used in the market, the front and rear foundation supports are mostly ground bolt foundations. For the fixed junction box part, most of them will lock square guide rails between the ground bolts. However, for this part of the guide rail, it is often only affected by the gravity of the junction box, and the force in other directions is very little affected. This will cause the square guide rail to have too much excess strength in the non-gravity direction, and the material cannot be fully utilized, and the utilization rate is very low. On the other hand, the excess material strength will also lead to an increase in project costs. Utility Model Content
