Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic module technology, and more specifically to a photovoltaic frame structure that prevents water accumulation. Background Technology
[0002] A photovoltaic (PV) module is a unit of photovoltaic cells that is integrated with encapsulation and internal connections, and is the smallest indivisible combination of photovoltaic cells that can independently provide DC power output. As the smallest effective power generation unit, the PV module undertakes the function of photoelectric conversion in a photovoltaic power station and is the core part of the photovoltaic power generation system. The PV frame is a key auxiliary material of the solar PV module. It is located on the outermost layer of the module and is mainly used to fix, seal and protect the internal structure such as cells, glass, and backsheet, and to enhance the strength of the module.
[0003] After the existing photovoltaic frames are fixed to the solar panels, rainwater, melted snow, or dew that accumulates when it is damp can easily accumulate at the connection between the frame and the solar panel during long-term outdoor use. Even if the solar panel is placed at an angle, there is still a height difference between the frame and the solar panel at the connection, which leads to water accumulation. Moreover, the water can only be dissipated through evaporation over a long period of time, and long-term water accumulation affects the lifespan of the photovoltaic modules. Secondly, the existing photovoltaic frames are not easy to disassemble and replace after they are fixed to the solar panels. Replacement after water damage to the frame becomes cumbersome and detrimental to use. Utility Model Content

At the same time, a small gap is left between the structural adhesive and the second frame 3 to form a water guide channel. When water flows to the connection between the solar panel 1 and the second frame 3, the water flows into the second water guide channel 303 through the water guide channel between the solar panel 1 and the second frame 3. Through the inclined structure of the second water guide channel 303, the rainwater flows out quickly from the second water outlet 505 under the action of gravity, which helps to prevent water accumulation between the photovoltaic frame and the solar panel 1.

The bottom of the first water guide groove 202 is an inclined structure. A first cavity 203 is provided in the middle of the front of the side frame body 201.

[0028] The working principle of this utility model:
[0029] The solar panel 1 is fixed to the second frame 3, and structural adhesive is fixed at the connection between the solar panel 1 and the second frame 3. A gap is left between the structural adhesive and the second frame 3 to form a water channel. When water flows to the connection between the solar panel 1 and the second frame 3, the water flows through the water channel between the solar panel 1 and the second frame 3 into the second water channel 303. Due to the inclined structure of the second water channel 303, rainwater quickly flows out from the second water outlet 505 under the action of gravity, which helps prevent water accumulation between the photovoltaic frame and the solar panel 1. The solar panel 1 is fixed to the first frame 2, and the connection between the solar panel 1 and the first frame 2 is also fixed. The sealing rubber strip ensures a tight seal, allowing water to flow to the bottom under gravity. Simultaneously, the first water guide groove 202 inside the first frame 2 serves as a preventative measure; when the sealing rubber strip's seal deteriorates, water will flow into the first water guide groove 202 and out through the first water outlet 504. For subsequent disassembly and maintenance of the photovoltaic frame, the fixing bolts 503 are used to secure it to the first connector 205 and the second connector 306 respectively. Simultaneously, the receiving groove 506 and the solar panel 1 cooperate to limit and fix the position, improving the stability of the photovoltaic frame's fixation. This facilitates the rapid disassembly and installation of the second fixing component 5, and subsequently, the rapid disassembly and maintenance of the photovoltaic frame.
