Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic support structures, in particular to a purlin connection waterproof structure. Background Art

[0002] The solar photovoltaic power generation structure includes photovoltaic panels and a bracket structure that fixes and supports the photovoltaic panels. Among them, the purlin is a part of the photovoltaic bracket structure and is an important structural component that connects the photovoltaic panels and fixes them to the bracket body. Solar photovoltaic panels are usually installed on the roof to facilitate sunlight exposure.

[0003] Since photovoltaic panels are usually installed and fixed over a relatively large area, the traditional one-piece purlin structure is difficult to transport and install due to its long length, so it is gradually replaced by multi-section purlins. However, when installing and connecting multi-section purlins, the alignment of the purlins is prone to deviation, resulting in a large gap between the connection position of adjacent purlins and the installed photovoltaic panels, and it is difficult to seal, which makes it easy to cause water leakage in the space under the photovoltaic panels on rainy days.
