[0037] like Figures 1 to 14As shown in Example 1, an easily detachable installation structure of a photovoltaic module includes:

[0038] A photovoltaic module 1 having a mounting rail 2 on its back, the front of which is fixed to the back of the photovoltaic module 1, and a bolt slot 3 on the back of the mounting rail 2. There are at least two mounting rails 2, which are parallel to each other, and the ends of the mounting rails 2 extend to the two side edges of the photovoltaic module 1 respectively;

[0039] Bottom beam 4, bottom beam 4 is located on both sides of the mounting rail 2 and is perpendicular to the mounting rail 2. Bottom beam 4 is installed on the mounting foundation, and the front side of bottom beam 4 has bolt slot 3;

[0040] An adapter plate 5, both ends of which have mounting holes 6;

[0041] 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 the adapter plates 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 adapter plates 5 is: one end of the adapter plate 5 is connected to the mounting rail 2 through the bolt groove 3 embedded in the mounting rail 2 and the bolt assembly 7 passing through the mounting hole 6, and the other end of the adapter plate 5 is connected to the bottom beam 4 through the bolt groove 3 embedded in the bottom beam 4 and the bolt assembly 7 passing through the mounting hole 6.

[0042] like Figure 14 As shown, the adjacent mounting rails 2 of the two photovoltaic modules 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 their respective adapter plates 5. There are two bolt slots 3 on the bottom beam 4 in the middle of the two photovoltaic modules 1 installed side by side, which are arranged side by side with each other. The adapter plates 5 on the adjacent ends of the adjacent mounting rails 2 of the two photovoltaic modules 1 installed side by side are placed side by side and staggered on the bottom beam 4, and are connected to the bottom beam 4 through two bolt assemblies 7 embedded in their respective bolt slots 3.

[0043] There is one bolt groove 3 on the bottom beam 4 located on the outer side of the photovoltaic assembly 1 at the edge.

[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] 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. The bottom beam 4 is fixed to the installation foundation through the horizontal fixing plate.

[0046] like Figure 1 and 2As shown, the bottom beam 4 located outside the edge of the photovoltaic module 1 is called the edge bottom beam, and the bottom beam 4 located between two photovoltaic modules 1 installed side by side is called the middle bottom beam. Figure 3 and 4 As shown, the middle bottom beam is equivalent to being formed by combining two edge bottom beams into one body. The number of the beam body 4-1 and the T-shaped support body 4-2 of the edge bottom beam is 1, while the number of the middle bottom beam is 2.

[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 the bottom beam 4 are profiles. The mounting rail 2 is flush with the edge of the photovoltaic module 1 or slightly recessed by about 5mm. Figure 5 and 6 As shown, the adapter plate 5 is a square aluminum block or steel block, and the mounting holes 6 at both ends are round holes and slotted holes respectively. The round holes are used to mount the guide rails 2, and the slotted holes are used to mount the bottom beams 4. Figure 7 and 8 As shown, the mounting rail 2 is a square tube with a flat upper surface for bonding the back of the photovoltaic module 1 with a structural adhesive 8, and a bolt groove 3 on the lower surface, which is connected to the adapter plate 5 through a bolt assembly 7.

[0051] The existing installation method of gluing the roof and the bracket on the roof is difficult to disassemble. However, the utility model pre-bonds the installation guide rail 2 on the back of the photovoltaic module 1 with structural glue 8, and adds a bottom beam 4 and an adapter plate 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 adapter plate 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 adapter plate 5 and the bottom beam 4. This completes the entire installation process.

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

[0061] The bolt assembly 7 on the adapter plate 5 connected to the photovoltaic module 1 to be disassembled is removed to release the connection between the adapter plate 5 and the bottom beam 4 and remove the photovoltaic module 1.

[0062] like Figure 15 As shown, Example 2, an easily detachable installation structure of a photovoltaic module, is basically the same as Example 1, with the difference that: the number of bolt grooves 3 on the bottom beam 4 between the two photovoltaic modules 1 installed side by side is one, and the adapter plates 5 on the adjacent ends of the adjacent mounting rails 2 of the two photovoltaic modules 1 installed side by side are overlapped and stacked on the bottom beam 4, and are connected to the bottom beam 4 through the same bolt assembly 7.

[0063] Compared to Example 1, the solution of using a common bolt assembly 7 for connecting the two adapter plates 5 to the bottom beam 4 in Example 2 can save the number of bolt assemblies 7 and save floor space. When disassembling, the photovoltaic assembly 1 in the upper position can be directly disassembled, while the photovoltaic assembly 1 in the lower position needs to be disassembled after the photovoltaic assembly 1 on both sides is removed. If the photovoltaic assembly 1 in the upper position is located at the outermost side, it is necessary to add an adapter plate 5 on the outer side of the photovoltaic assembly 1 at the edge to ensure that the two sides of the photovoltaic assembly 1 are at the same height.

[0064] Example 3, an easily detachable installation structure of a photovoltaic module, is basically the same as Example 1, except that the adjacent ends of the adjacent mounting rails of two photovoltaic modules installed side by side are connected to separate bottom beams 4 through respective adapter plates, rather than sharing a common bottom beam 4 as in Examples 1 and 2.
