Technical Field

The utility model relates to a photovoltaic frame subassembly installation technical field especially relates to a drainage structure of photovoltaic module frame.

Background

The aluminum alloy frame of the photovoltaic module for fixing and supporting the external structure is called a photovoltaic frame and is formed by a rectangular frame consisting of two long frames and two short frames. As shown in fig. 1, an existing photovoltaic module frame can be basically divided into 4 surfaces, i.e., an a surface, a B surface, a C surface and a D surface; the A surface is used for preventing the laminate from escaping, the B \ D surfaces mainly bear the frame strength and the overall strength of the assembly and are the core of the mechanical strength of the photovoltaic assembly, the C surface is used for preventing the frame from being stressed and twisted and preventing the connecting surface of the fastener from being installed, and M6\ M8 bolts are generally adopted to be connected on a bracket through a through hole with the diameter of 9mm on the C surface, and 27448 is adopted.

The existing photovoltaic frame mounting structure is shown in figure 2, the thickness of the surface A is generally between 2.5 mm and 3mm, so that the height difference is formed between the surface of a laminating piece and the surface of the surface A, in the mounting application scene with a small inclination angle, sewage and rainwater on the surface of a component are accumulated below the component due to the blocking of the surface A of the frame, stains cover a battery piece after water evaporation, the power generation efficiency of the component is influenced, and the component is damaged due to hot spot phenomenon in serious cases.
