Method for manufacturing fixed frame structure for solar panel

More and more solar panels are used in industrial production and people's lives. Solar panels are installed on roofs or in open spaces to better absorb solar energy. The existing solar panels are formed by splicing a number of borders. Waterproof glue is applied between the solar panels and the frame for waterproofing. Waterproof glue is also applied between the frames to avoid water seepage, thus causing encounters with certain solar energy. It is very difficult to repair the board when it fails, which reduces the overall solar panel usage.

Detailed ways

In order to further explain the technical solutions of the present invention, the present invention will be described in detail below through specific embodiments.

As shown in the figure, the utility model discloses a fixed frame structure for solar panel, which comprises a first frame A and a second frame B which are oppositely disposed, and two third frames C at the two ends of the first frame A and the second frame B respectively. . The first frame A and the second frame B have a structure that is engaged with each other, so that adjacent solar panels are engaged and spliced with each other by a fixed frame structure.

The first frame A includes a first step surface 1 and a first mounting surface 2, and the first step surface 1 includes a first first engaging surface 11 , a first drainage surface 12 , and a longitudinal first side 13 and a locking surface 14; the first mounting surface 2 is provided with a first mounting groove 21 and a first locking surface 22 respectively opposite to the first side surface 13 and the first locking surface 14, the first mounting groove 22 For fixing the solar panel D; the first locking surface 14 is opposite to the first locking surface 22 and is provided at both ends thereof with mounting holes d extending through the two. A cavity a is formed between the first locking surface 14 and the first locking surface 22 to facilitate weight reduction.

The second frame B includes a second step surface 3 and a second mounting surface 4, and the second step surface 3 includes a second lateral engaging surface 31, a second drainage surface 32, and a longitudinal second side 33 and a second locking surface 34; the second mounting surface 4 is provided with a second mounting groove 41 and a second locking surface 42 opposite to the second side surface 33 and the second locking surface 34, respectively. The second locking surface 34 and the second locking surface 42 are opposite to each other and are provided at both ends thereof with mounting holes d extending through the two. A cavity a is formed between the second locking surface 34 and the second locking surface 42 to facilitate weight reduction; a cavity a is also formed between the second side surface 33 and the second mounting groove 41 to further reduce the weight.

The third frame C includes a third mounting groove 51 for fixing the solar panel D and a locking portion 52 connecting the first frame A and the second frame B, and the locking portion 52 corresponds to the first frame A and the The mounting hole d of the two frame B is connected to the locking portion 52 through the mounting hole d of the screw e, and the third frame C is combined with the first frame A and the second frame B to form a rectangular structure. For ease of molding, the locking portion 52 has a C-shaped cross section. The third frame is further formed with a third step surface relative to the outer side surface of the third mounting groove, and the third step groove of the different solar panel frame can be fixed on the mounting bracket by the T-shaped bead.

The key point of the present invention is that the width L1 of the first drainage surface 12 is smaller than the width L2 of the second drainage surface 32, and the width L3 of the first engagement surface 11 is greater than the first drainage surface 12 and the second drainage surface 32. 

The width of the difference is that the outer edge of the first engaging surface 11 is formed with an inward hook portion 111, and the second engaging surface 31 forms a slot 311 for engaging the hook portion 111; After the second frame B is engaged with each other by the hook portion 111 and the card slot 311 (see FIGS. 7, 8, and 9), the first drainage surface 12 is different due to the difference in the width of the second drainage surface 32 of the first drainage surface 12. The first locking surface 14, the first engaging surface 11 and the second drainage surface 32 and the second locking surface 34 form a drainage cavity b so as to penetrate the gap existing between the first frame A and the second frame B. The rainwater can flow out through the drainage chamber b, preventing the infiltration of rainwater from affecting the normal operation of the solar panel D and other components of the solar panel.

Further, in order to enhance the waterproof performance, a waterproof strip 23, a first mounting groove 21, and a second mounting are disposed between the solar panel D and the first mounting groove 21, the second mounting groove 41, and the third mounting groove 51. The groove of the groove 41 and the third mounting groove 51 is formed with a hook portion 211 inwardly, and the waterproof strip 23 is provided with a groove 231 matching the hook portion 211; the waterproof strip may have a V-shaped structure, and the opening is opened outward to The waterproof strip 23 is better fitted into the first mounting groove 21, the second mounting groove 41, and the third mounting groove 51.

5 and FIG. 6, when the utility model is combined, the solar panel D is first fitted with the waterproof strip 23 and then mounted to the first mounting groove 21 of the first frame A, the second frame B, and the third frame C, and the second installation. The slot 41 and the third mounting slot 51 are finally connected to the locking portion 52 of the third frame C through the mounting holes d of the first frame and the second frame by screws e, respectively, and the first frame A and the second frame B respectively The two ends are matched to the two third frames C to form a rectangular frame.

The utility model adopts the connection structure of the hook portion 111 of the first frame A and the second frame B and the card slot 311 to facilitate the splicing and splicing and disassembly between the plurality of solar panel fixing frames, the installation efficiency is high, and the first drainage The surface 12 and the second drainage surface 32 have a difference in width, so that after the first frame A and the second frame B are engaged, the first drainage surface 12, the first locking surface 14, the first engaging surface 11 and the second drainage surface 32 and the second locking surface 34 form a drainage cavity b, so that the rainwater which penetrates the gap between the first frame A and the second frame B can flow out through the drainage cavity b, has good waterproof performance, and avoids the influence of rainwater infiltration. The solar panel D and other components of the solar panel work normally, so the utility model does not need to be waterproofed by waterproof glue, and is convenient for disassembly and maintenance.
