[0036] Example 1

[0037] refer to Figures 1-4 This utility model provides a photovoltaic support connection structure, including: a lower pressure block 1, an upper pressure block 2, and a fixing connector 3. The lower pressure block 1 includes a first bearing part 11 and a first mounting part 12. The upper pressure block 2 includes a second bearing part 21 and a second mounting part 22. A portion of the inner surface of the second bearing part 22 is attached and fixed to the outer surface of the first bearing part 11.

The limiting space 10 is configured to accommodate the frame 4 of the photovoltaic module. The inner surface of the first bearing part 11 and the other portion of the inner surface of the second bearing part 21 form a fixing space 20. The fixing connector 3 is located in the fixing space 20, and the top outer surface of the fixing connector 3 is attached and fixed to the inner surface of the second bearing part 21. The frame 4 has a top wall, a side wall, and a bottom wall connected in sequence, wherein the extension direction of the top wall corresponds to the A-side direction of the frame 4, the extension direction of the side wall corresponds to the B-side direction of the frame 4, and the extension direction of the bottom wall corresponds to the C-side direction of the frame 4. Figure 2 , Figure 8 The dashed line in the middle represents the boundary line between the first bearing part 11 and the first mounting part 12. Figure 4 The dashed line represents the boundary line between the second bearing part 21 and the second mounting part 22.

[0038] In some embodiments, a limiting structure is provided on the first mounting part 12. The limiting structure is configured to abut and fix the frame 4 to the lower pressure block 1 so as to clamp the frame 4 between the upper pressure block 2 and the lower pressure block 1, thereby realizing the pre-fixing operation of the frame 4.

[0039] refer to Figure 1 , Figure 2 In a further optimized scheme, the first mounting part 12 includes a side part 121 and a bottom part 122, wherein the side part 121 is connected to one end of the first support part 11 and extends in a bent manner relative to the first support part 11, and the bottom part 122 is connected to the other end of the side part 121 and extends toward the C-side of the frame 4.

[0040] refer to Figure 1 , Figure 2 In a further optimized scheme, the limiting structure includes a limiting groove 123, wherein the limiting groove 123 is disposed at the end of the bottom edge 122 away from the side edge 121, and cooperates with the end of the bottom wall of the frame 4 away from its side wall.

[0041] refer to Figures 1-4 In a further optimized design, the tops of the first support portion 11, the second support portion 21, and the fixed connector 3 are fixed together by mounting bolts 5. Specifically, a first mounting hole 10 can be provided on the first support portion 11, a second mounting hole 20 can be provided on the second support portion 21, and a third mounting hole 30 can be provided on the top of the fixed connector 3. The positions of the first mounting hole 10, the second mounting hole 20, and the third mounting hole 30 correspond one-to-one so that the mounting bolts 5 can fix the tops of the first support portion 11, the second support portion 21, and the fixed connector 3 together from bottom to top.

[0042] Continue to refer to Figure 1 , Figure 3 In a further optimized scheme, the fixed connector 3 is provided with a through groove 31 along its own thickness direction. The through groove 31 is configured to engage the steel cable 6 extending along the C side direction of the frame 4 so that the steel cable 5 supports the pressure block 1.

[0043] refer to Figure 1 , Figure 3 , Figure 5 In a further optimized design, through holes 32 are provided on both sides of the fixed connector 3. The through holes 32 are configured to be passed through by both ends of the U-bolt 7 so that the frames 4 of two adjacent photovoltaic modules are fixed together.

[0044] With the above connection structure, the installation process of this utility model is as follows: First, the bottom wall of the lower pressure block 1 and the frame 4 are connected by the limiting groove 123, and the inner surface of the second bearing part 22 is attached to the outer surface of the first bearing part 11 to form the limiting space 10 and the fixing space 20. Then, the fixing connector 3 is placed in the fixing space 20, and the lower pressure block 1, the upper pressure block 2 and the fixing connector 3 are firmly connected by the mounting bolt 5. The fixing connector 3 is then installed on the steel cable 6 by the through groove 31. Finally, the frames 4 of the two adjacent photovoltaic modules are fixed together on the steel cable 6 by the U-bolt 7, thus completing the installation process of the photovoltaic module.

[0045] Based on the above method, since the upper pressure block 2 and the lower pressure block 1 adopt the pre-fixing operation, the high-altitude installation process is changed to be carried out on the ground. The frame 4 can be temporarily fixed to the steel cable 6 through the fixed connector 3, thereby reducing the installation difficulty of photovoltaic modules. Even without manual support, the frame will not slip, reducing the need for manpower and improving the installation efficiency.

[0046] Example 2

[0047] refer to Figures 6-8 This utility model also provides another photovoltaic bracket connection structure, which differs from Embodiment 1 in that the first mounting part 12 adopts an optimized limiting structure.

[0048] The optimized limiting structure includes a limiting barb 124 and a limiting opening 125 that cooperates with the limiting barb 124. For details, see [link to documentation]. Figure 7 The limiting port 125 is connected to the inner surface of the side wall of the frame 4, and the opening direction of the limiting port 125 is parallel to the direction of side B of the frame 4; see also Figure 8 The limiting hook 124 faces the opening direction of the limiting port 125 and is connected to the outer surface of the side portion 121.

[0049] refer to Figures 6-8 In the further optimized scheme, there are two limit hooks 124 and two limit openings 125. The two limit hooks 124 and the two limit openings 125 are distributed along the B side direction of the frame 4, thereby preventing the frame 4 from slipping off from the B side direction.

[0050] With the above connection structure, the installation process of this utility model is as follows: First, the bottom wall of the lower pressure block 1 and the frame 4 are connected by the cooperation of the limiting hook 124 and the limiting port 125. The inner surface of the second bearing part 22 is attached to the outer surface of the first bearing part 11 to form the limiting space 10 and the fixing space 20. Then, the fixing connector 3 is placed in the fixing space 20. The lower pressure block 1, the upper pressure block 2 and the fixing connector 3 are firmly connected by the mounting bolt 6. The fixing connector 3 is further installed on the steel cable 6 through the through groove 31. Finally, the frames 4 of the two adjacent photovoltaic modules are fixed together on the steel cable 6 by the U-bolt 7, thus completing the installation process of the photovoltaic module.

[0051] Based on the above method, since the upper pressure block 2 and the lower pressure block 1 adopt the pre-fixing operation, the high-altitude installation process is changed to be carried out on the ground. At the same time, the combination design of the limiting hook 124 and the limiting port 125 effectively prevents the frame 4 from slipping off from the B side, improving the connection firmness of the pre-fixing operation. The frame 4 can be temporarily fixed on the steel cable 6 through the fixed connector 3, thereby reducing the installation difficulty of the photovoltaic module. Even without manual support, the frame will not slip, reducing the need for manual labor and improving the installation efficiency.
