Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0034] The embodiment of the present invention provides an easily disassembled and assembled structure for a solar module roof, and the structure design is optimized to solve the problems of difficult disassembly of photovoltaic modules, difficult control of the amount of glue used in glue installation, and the influence of installation weather conditions.

[0035] As Figures 1 to 13 shown, an easily disassembled and assembled structure for a solar module roof includes a photovoltaic module 5, a bracket, a pressing block 3, and a cross beam 6. The bracket is pre-bonded to the backlight side of the photovoltaic module 5, and a groove 2.21 is formed on the bracket. The pressing block 3 catches the groove 2.21 and is provided with bolt holes to realize the fixed connection of the bracket, the pressing block 3, and the roof cross beam 6. Specifically,

[0036] The cross beam 6 is Figure 1 shown, and is integrally strip-shaped and installed on the color steel tile roof along the setting direction of the photovoltaic module 5. The cross section of the cross beam 6 is in an I shape, and grooves 2.21 are formed on both the upper surface and the lower surface. The groove 2.21 on the upper surface is connected to the pressing block 3 by screws, and the groove 2.21 on the lower surface is connected to a fixture (not shown in the figure) of the color steel tile roof. During installation, a nut 4.1 is arranged in the groove 2.21 for cooperating with a bolt 4 for connection.

[0037] The bracket is Figure 2 、 Figure 3 and Figure 7As shown in the figure, it includes a long strip-shaped hollow guide rail 1 and an adapter block 2. The hollow guide rail 1 is a hollow square aluminum tube; the adapter block 2 includes a first connecting portion 2.1 and a second connecting portion 2.2 that are connected to each other. In this embodiment, the adapter block 2 is integrally T-shaped, that is, one end of the first connecting portion 2.1 is connected to the middle of the second connecting portion 2.2, and the other end of the first connecting portion 2.1 extends into the guide rail 1 and is connected to the guide rail 1. The second connecting portion 2.2 is provided with a groove 2.21 for clamping with the pressing block 3. Both the first and second connecting portions are hollow square aluminum tubes. Among them, chamfering treatment is performed at the outer corner of the first connecting portion 2.1, so that the outer corner is an inclined section 2.21, and it is connected to the inner side surface of the guide rail 1 through this inclined section 2.21, making the behavior of inserting the first connecting portion 2.1 into the cavity of the guide rail 1 smoother. At the bottom end of the first connecting portion 2.1, that is, on the inner contact surface with the cavity of the guide rail 1, there is an anti-retreat convex block 2.22, which is a serrated structure in this embodiment to prevent the adapter block 2 from coming out. There is also a reinforcing rib in the cavity of the first connecting portion to enhance the strength of the component. A groove 2.21 is opened at the bottom end of the second connecting block. The groove 2.21 is parallel to the long side of the photovoltaic module 5, and the pressing block 3 hooks the groove 2.21 to achieve installation and locking. It should be noted that the adapter block can also be an L-shaped or other shape where one end of the first connecting portion and the second connecting portion are connected. As long as it can connect the guide rail 1 and has a groove to achieve the clamping of the pressing block, it is within the protection scope of the present utility model; in this embodiment, the adapter block 2 and the guide rail 1 are clamped by an angle code, but the present utility model is not limited to this connection method, and it can also be other connection forms such as welding. When it is a welding connection, the second connecting portion with a groove is directly welded to the guide rail. The bracket is pre-bonded with the photovoltaic module 5 through silicone 7, etc. in the factory.

[0038] The pressing block 3 is as Figures 4 to 5 shown, and includes opposite lower pressing arms 3.23.1 and lower pressing arms. The lower pressing arm 3.23.1 contacts the surface of the photovoltaic module 5 and is provided with an anti-slip and buffer pad such as silicone 7 and sponge on the contact surface with the photovoltaic module 5. The lower pressing arm contacts the bracket and has a clamping post matching the bracket groove 2.21. Bolt holes are opened on the upper and lower pressing arms of the pressing block 3. The bolt 4 passes through the upper and lower pressing arms and is connected to the cross beam 6. The tightness of the upper and lower pressing arms is adjusted by the depth of the bolt 4 embedded in the cross beam 6. The bolt is as Figure 6 shown. The photovoltaic modules 5 are arranged in an array on the roof. The edge photovoltaic modules 5 of the array are fixed by edge pressing blocks 3, as Figure 4 shown. For the photovoltaic modules 5 in the middle of the array, double-sided pressing blocks 3 are used for fixing, as Figure 5 shown. The edge pressing block 3 is a pressing block 3 with a pair of upper and lower pressing arms, and the double-sided pressing block 3 is a pressing block 3 with two pairs of upper and lower pressing arms.

[0039] Installation method:

[0040] Pre-bonding of the guide rail 1 and the photovoltaic module 5: First, combine the guide rail and the adapter block together. The combination method can be welding or snap connection, and the surface is flat after combination. Then, bond the combined guide rail 1 and the back of the photovoltaic module 5 with silicone 7 at the designed position, and wait for the silicone 7 to cure before packaging and shipping.

[0041] Installation of the photovoltaic module 5: First, install the cross beam 6 and install the cross beam 6 at the designed spacing. Fix the bottom surface of the cross beam 6 to the roof. Then, install the photovoltaic module 5. Take out the photovoltaic module 5 and the pressing block 3, slide the lower pressing arm of the pressing block 3 into the groove 2.21 of the adapter block 2 from the side, place the lower pressing arm 3.23.1 of the pressing block 3 on the front of the module, and lock the upper and lower pressing arms and the cross beam 6 together through the bolt 4 and the nut 4.1.

[0042] Disassembly of the module: Loosen the bolt 4 of the pressing block 3 connected to the module to be disassembled. After removing the pressing block 3, lift the module upward to easily disassemble the photovoltaic module 5.

[0043] The easily disassembled and assembled structure disclosed by the present invention pre-bonds the entire guide rail to the back of each module in the installation structure. The guide rail is retracted inside the module, which is convenient for packaging the module. The guide rail is composed of a square aluminum tube and an adapter block. The adapter block and the square are combined by welding or corner code snap connection. The lower bottom of the adapter block is provided with a groove parallel to the long side of the module. The installation uses a pressing block. The lower pressing arm of the pressing block has an upward clamping post that extends into the groove of the adapter block. The module is fixed by pressing the upper pressing arm of the pressing block against the glass of the module and clamping the adapter block below. When disassembling, remove the bolt pressing block to remove the module. The disassembly is simple and will not damage the module, having good application scenarios and industrial value.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
