Frameless photovoltaic module mounting bracket

Abstract

The invention provides a borderless photovoltaic module mounting bracket, and relates to the technical field of photovoltaic power generation. The bracket comprises two or more first struts arranged in parallel with each other and two or more second struts arranged in parallel with each other. Each second strut is arranged between two adjacent first struts and perpendicularly intersects the first struts. The middle of each second strut is provided with a first slot and a second slot, wherein the first slot and the second slot are arranged back to back and form an I-shaped structure. The height between upper and lower surfaces of each first slot and the height between upper and lower surfaces of each second slot are greater than the thickness of the borderless photovoltaic module. The top of each first strut is provided with a positioning slot used for supporting a second strut, or the side wall of the first strut is provided with a stepped surface used for supporting the end of the second strut. The top of each first strut is provided with a glue injection slot along the length direction. According to the invention, the borderless photovoltaic module in a roof photovoltaic system can be easily fixed, and the roof photovoltaic system has a good sealing waterproof performance.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a mounting bracket for a frameless photovoltaic module. Background technique [0002] The Chinese invention patent with the notification number CN105119556B discloses a frameless photovoltaic module mounting bracket and a rooftop photovoltaic system. For the requirements of the building, the specific method is to install the No. 1 pole and the No. 2 pole on the roof as the main support frame, and then apply glue in the glue injection groove of the No. 1 pole and the slot of the No. 2 pole To fix the frameless photovoltaic module, although this installation method is simple, because one end of the frameless photovoltaic module is inserted into the slot of the No. 2 pole, and the other end is only fixed on the No. The bonding effect of the frameless photovoltaic module near this end and the adhesive will gradually decrease (especially when the No. The same s...

[0002] The Chinese invention patent with the notification number CN105119556B discloses a frameless photovoltaic module mounting bracket and a rooftop photovoltaic system. For the requirements of the building, the specific method is to install the No. 1 pole and the No. 2 pole on the roof as the main support frame, and then apply glue in the glue injection groove of the No. 1 pole and the slot of the No. 2 pole To fix the frameless photovoltaic module, although this installation method is simple, because one end of the frameless photovoltaic module is inserted into the slot of the No. 2 pole, and the other end is only fixed on the No. The bonding effect of the frameless photovoltaic module near this end and the adhesive will gradually decrease (especially when the No. The same structure with a sloped surface, which is prone to stress concentration in the curved part, which leads to local separation from the adhesive), although it does not affect the overall stability of the photovoltaic module, once the adhesive in some parts is connected to the borderless When the photovoltaic module is detached and there is a gap, it will lead to leaks in the waterproof sealing of the photovoltaic system, especially in heavy rain and heavy rain, the rainwater holding capacity of the drainage tank is insufficient, and rainwater can easily enter the gap caused by the failure of the adhesive , and eventually fall into the bottom of the frameless photovoltaic modules, causing water leakage in the roof photovoltaic system
