[0038] like Figures 1 to 15 As shown, a photovoltaic assembly easily detachable installation structure includes:

[0039] At least two photovoltaic modules 1 are installed side by side, and the back of the photovoltaic module 1 has a mounting rail 2. The front of the mounting rail 2 is fixed to the back of the photovoltaic module 1. The back of the mounting rail 2 has a bolt slot 3. There are at least two mounting rails 2, which are parallel to each other, and the two ends of the mounting rail 2 extend to the two side edges of the photovoltaic module 1, such as Figure 5 、 6 and 7;

[0040] Bottom beam 4, bottom beam 4 is located on both sides of the installation guide rail 2 and is perpendicular to the installation guide rail 2. Bottom beam 4 is installed on the installation foundation. The front side of bottom beam 4 has bolt groove 3, as shown in FIG. Figure 1 、 2 and 13;

[0041] The L-shaped auxiliary connecting block 5 is L-shaped, and both ends of the L-shaped auxiliary connecting block 5 have mounting holes 6, such as Figure 3 As shown;

[0042] Among them, the photovoltaic component 1 is installed on the bottom beams 4 on both sides through the mounting rails 2, and the two ends of the mounting rails 2 are connected to the bottom beams 4 on both sides through L-shaped auxiliary connecting blocks 5. The specific structure of the end of the mounting rail 2 being connected to the bottom beam 4 on the same side through the L-shaped auxiliary connecting blocks 5 is as follows: one end of the L-shaped auxiliary connecting block 5 is connected to the mounting rail 2 through a bolt assembly 7 embedded in the bolt groove 3 of the mounting rail 2 and passing through the mounting hole 6, and the other end of the L-shaped auxiliary connecting block 5 is connected to the bottom beam 4 through a bolt assembly 7 embedded in the bolt groove 3 of the bottom beam 4 and passing through the mounting hole 6. The adjacent mounting rails 2 of the two photovoltaic components 1 installed side by side are arranged in the same straight line, and the adjacent ends of the two are connected to the same bottom beam 4 through two L-shaped auxiliary connecting blocks 5 in opposite directions and staggered from each other.

[0043] like Figure 8 As shown, the directions of the L-shaped auxiliary connection blocks 5 located on both sides of the mounting rail 2 are opposite, and the directions of the L-shaped auxiliary connection blocks 5 located on the same side of the mounting rail 2 are the same.

[0044] The bottom beam 4 is segmented, and each segment of the bottom beam 4 corresponds to a mounting rail 2. Of course, the bottom beam 4 may be a whole segment.

[0045] like Figure 1 As shown, the bottom beam 4 includes a beam body 4-1 and a T-shaped support body 4-2. The T-shaped support body 4-2 includes a vertical support plate and a horizontal fixing plate. The T-shaped support body 4-2 is supported at the bottom of the beam body 4-1, and the bottom beam 4 is fixed to the installation foundation through the horizontal fixing plate.

[0046] The number of the bolt groove 3 on the front surface of the bottom beam 4 for connecting the L-shaped auxiliary connecting block 5 is one.

[0047] The bottom beam 4 is fixed to the installation foundation by means of structural adhesive 8 .

[0048] The installation foundation is the roof.

[0049] The front side of the mounting rail 2 is fixed to the back side of the photovoltaic module 1 by means of structural adhesive 8 .

[0050] The mounting rail 2 and bottom beam 4 are profiles. The mounting rail 2 is flush with the edge of the photovoltaic module 1 or slightly indented by about 5mm. The L-shaped auxiliary connecting block 5 is an aluminum block or a steel block, and the mounting holes 6 at both ends are round holes and straight holes respectively. The round holes are used to match the mounting rail 2, and the straight holes are used to match the bottom beam 4. Figure 3 The mounting rail 2 is a square tube with a flat upper surface for bonding the back of the photovoltaic module 1 with structural adhesive 8. The lower surface has bolt slots 3, which are connected to the L-shaped auxiliary connecting block 5 by bolt assemblies 7. The two L-shaped auxiliary connecting blocks 5 connected to the same bottom beam 4 in opposite directions and staggered with each other can complement each other after installation, forming a "mouth" shape, as shown in FIG. Figure 4 shown.

[0051] The existing installation method of gluing the photovoltaic module 1 to the roof and the bracket on the roof is difficult to disassemble. However, the utility model pre-bonds the mounting rail 2 on the back of the photovoltaic module 1 with structural adhesive 8, and adds a bottom beam 4 and an L-shaped auxiliary connecting block 5. The photovoltaic module 1 can be separated from the roof by removing the bolt assembly 7, and the photovoltaic module 1 can be easily disassembled.

[0052] The existing detachable installation method has a complex structure, high cost and is not simple to install and disassemble. However, the utility model has a simple structure, low installation cost, and is easy to install and disassemble.

[0053] The existing installation method uses glue to bond the roof and the bracket on the roof. The on-site gluing construction environment is relatively harsh, and dust and rain will affect the bonding effect. The bonding work of the utility model can be completed inside the factory, and the gluing quality is more guaranteed.

[0054] At the same time, on-site gluing has weak bonding strength at the beginning, and construction cannot be carried out in windy weather, and there is a risk that the photovoltaic components 1 will be blown off. However, the bonding work of the present invention can be completed inside the factory, with better curing conditions and longer curing time, which can avoid the impact of windy weather.

[0055] The installation process of photovoltaic module 1 is as follows:

[0056] 1. The photovoltaic module 1 is pre-installed with the mounting rail 2 in the factory. The mounting rail 2 is bonded to the back of the photovoltaic module 1 using structural adhesive 8.

[0057] 2. Install the bottom beam 4 on the roof using structural adhesive 8 according to the designed position;

[0058] 3. Take out the photovoltaic module 1 with the pre-installed mounting rail 2 on the back, and install the L-shaped auxiliary connecting block 5 at the end of the mounting rail 2 using the bolt assembly 7;

[0059] 4. After the structural adhesive 8 under the bottom beam 4 is initially cured, place the photovoltaic module 1 on the bottom beam 4 and use the bolt assembly 7 to lock the L-shaped auxiliary connecting block 5 and the bottom beam 4. This completes the entire installation process.

[0060] The disassembly process of photovoltaic module 1 is as follows:

[0061] Remove the bolt assembly 7 on the L-shaped auxiliary connecting block 5 connected to the photovoltaic module 1 to be disassembled, so as to release the connection between the L-shaped auxiliary connecting block 5 and the bottom beam 4 and remove the photovoltaic module 1.
