[0042] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0043] Embodiment 1 of this utility model provides a practical cable fixing device for a flexible bracket, such as... Figure 1 As shown, the flexible support cable fixing device includes a medium pressure block fixing device 1; the medium pressure block fixing device 1 is connected to the medium pressure block 3, and the medium pressure block 3 is used to fix adjacent photovoltaic modules 7 on the flexible support;

[0044] The medium pressure block fixing device 1 includes a medium pressure block fixing part 11 and a cable placement part 12 connected to each other;

[0045] The intermediate pressure block fixing part 11 has a first fixing hole 111, through which the intermediate pressure block fixing part 11 is connected to the intermediate pressure block 3; the cable placement part 12 includes an annular structure 121, the opening of the annular structure 121 facing upward for the cable to pass through.

[0046] In this embodiment, the intermediate pressure block 3 is first securely connected to the intermediate pressure block fixing part 11. The cable placement part 12 is used to allow the cable to pass through and wrap it, thereby preventing the cable from swaying, shifting laterally, or rotating, and preventing damage to the cable caused by these movements. Figure 7 As shown, this embodiment integrates the cable fixing function into the original fixing structure of the photovoltaic module 7. Compared with setting up a separate cable tray, this not only significantly reduces the number of parts and installation space requirements, but also greatly reduces the overall cost.

[0047] In this first embodiment, as Figure 2 As shown, the flexible support cable fixing device also includes an edge pressure block fixing device 2; the edge pressure block fixing device 2 is connected to the edge pressure block 4, and the edge pressure block 4 is used to fix the photovoltaic modules 7 arranged at the edge position on the flexible support;

[0048] The edge block fixing device 2 includes an edge block fixing part 21 and a cable fixing part 22 connected to each other;

[0049] The edge pressure block fixing part 21 has a second fixing hole 211, through which the edge pressure block fixing part 21 is connected to the edge pressure block 4; the cable fixing part 22 includes a reserved fixing hole 221, which is used for the fixing strap 5 to pass through and bind the cable.

[0050] The edge clamp fixing device 2 is connected to the transformer block 4 via the transformer block fixing part 21, fixing the cable into the structure of the edge photovoltaic module, avoiding the need for additional installation components and effectively saving space and material costs. In addition, the cable is fixed by the fixing strap 5, which can flexibly adjust the binding strength of the cable through the reserved fixing holes 221, thereby accommodating the fixing of cables of different specifications, ensuring that the cable can be stably installed at the edge position, and avoiding shaking or displacement caused by wind or other external forces.

[0051] like Figure 3 As shown, the middle pressure block 3 includes a left pressure plate 31, a right pressure plate 32, and a first connecting plate 33; the left pressure plate 31 and the right pressure plate 32 are used to press the adjacent photovoltaic modules 7 on the flexible support respectively;

[0052] The first connecting plate 33 has a first mounting hole 331, and the first connecting plate 33 is connected between the left pressure plate 31 and the right pressure plate 32 and is horizontally lower than the left pressure plate 31 and the right pressure plate 32; in use, such as Figure 5As shown, the first connecting plate 33 is fixed to the intermediate pressure block fixing part 11 through the first fixing hole 111 and the first mounting hole 331. By using bolts or other connecting parts passing through the first fixing hole 111 and the first mounting hole 331, the intermediate pressure block fixing part 11 and the first connecting plate 33 can be quickly assembled, ensuring the reliability of the connection between the intermediate pressure block fixing device 1 and the intermediate pressure block 3, while simplifying the installation steps.

[0053] The intermediate pressure block fixing part 11 includes a first pressure plate 112 and a first fixing plate 113 connected to each other;

[0054] One end of the first fixing plate 113 is connected to the cable placement part 12 and is located above the cable placement part 12 during use; the other end of the first fixing plate 113 is connected to the first pressure plate 112 and is located above the first pressure plate 112 during use.

[0055] The first fixing hole 111 is formed in the first fixing plate 113. The connecting plate 33 is fixed between the first fixing plate 113 and the first pressure plate 112 through the first fixing hole 111, and a certain pressure is applied to the first connecting plate 33 through the first pressure plate 112.

[0056] In this first embodiment, bolts and other connecting parts are passed sequentially through the first mounting hole 331 and the first fixing hole 111 on the first fixing plate 113 to fix the connecting plate 33 between the first pressure plate 112 and the first fixing plate 113. At the same time, the first pressure plate 112 applies downward pressure to the connecting plate 33 below. The combination of these two fixing methods can effectively prevent the middle pressure block 3 from loosening or shifting, thereby significantly enhancing the tightness of the connection between the middle pressure block 3 and the middle pressure block fixing device 1.

[0057] like Figure 4 As shown, the edge pressure block 4 includes a side pressure plate 41 and a second connecting plate 42 connected to each other; both the side pressure plate 41 and the second connecting plate 42 are horizontally arranged and connected to each other by a vertical plate. The side pressure plate 41 is higher than the second connecting plate 42 in the horizontal direction; wherein, the side pressure plate 41 is used to press the photovoltaic modules arranged at the edge position on the flexible bracket, the second connecting plate 42 has a second mounting hole 421, and the second connecting plate 42 is connected to the side pressure plate 41. The second connecting plate 42 is fixed to the edge pressure block fixing part 21 through the second fixing hole 211 and the second mounting hole 421.

[0058] When using, such as Figure 6As shown, the edge pressure plate 41 is used to press down on the photovoltaic modules at the edge position to resist external forces and prevent the photovoltaic modules from shifting. The second mounting hole 421 on the second connecting plate 42 is used to cooperate with the second fixing hole 211 of the edge pressure block fixing part 21, and is fixed by bolts or other connecting parts. This structure integrates the functions of fixing the photovoltaic modules at the edge position and fixing the cables, effectively saving materials and space, while improving the integration of the flexible bracket practical cable fixing device in this embodiment.

[0059] like Figure 2 As shown, the edge pressure block fixing part 21 includes a second pressure plate 212 and a second fixing plate 213 connected to each other; one end of the second fixing plate 213 is connected to the cable fixing part 22 and is located above the cable fixing part 22 during installation; the other end of the second fixing plate 213 is connected to the second pressure plate 212 and is located above the second pressure plate 212 during installation.

[0060] The second fixing hole 211 is provided in the second fixing plate 213. The second connecting plate 42 is fixed between the second fixing plate 213 and the second pressure plate 212 through the second fixing hole 211, and a certain pressure is applied to the second connecting plate 42 through the second pressure plate 212.

[0061] In this first embodiment, the side pressure block 4 and the side pressure block fixing part 21 are fixed by bolts and other connecting parts passing through the second mounting hole 421 and the second fixing hole 211 in sequence. At the same time, the second pressure plate 212 applies downward pressure to the connecting plate 42 below. The combination of these two fixing methods can effectively prevent the side pressure block 4 from loosening or shifting, thereby significantly enhancing the tightness of the connection between the side pressure block 4 and the side pressure block fixing device 2.

[0062] like Figure 5 As shown, the cable placement section 12 includes an annular sleeve 122; the annular sleeve 122 is fitted onto the annular structure 121, forming protection for the cable passing through the annular structure 121. The annular sleeve 122 can buffer the direct friction between the cable and the annular structure 121, avoiding insulation damage caused by long-term shaking and reducing the risk of short circuits.

[0063] Furthermore, the first pressure plate 112 in this embodiment also includes a first arc-shaped structure 114. In use, the opening of the first arc-shaped structure 114 faces upward, and the bottom of the first arc-shaped structure 114 is used to apply a certain pressure to the first connecting plate 33. The point contact between the bottom of the first arc-shaped structure 114 and the first connecting plate 33 concentrates the pressure in the key area, providing a stronger fastening force compared to the flat pressure plate, and effectively preventing the middle pressure block 3 from sliding laterally or loosening.

[0064] Similarly, the second pressure plate 212 also includes a second arc-shaped structure 214, which opens upwards and applies pressure to the second connecting plate 42 at its bottom. The point contact between the bottom of the second arc-shaped structure 214 and the second connecting plate 42 concentrates the pressure in the critical area, providing a stronger clamping force compared to the flat pressure plate, and effectively preventing the middle pressure block 4 from sliding or loosening laterally.

[0065] like Figure 7 As shown, the medium-pressure block fixing device 1 is fixed between two adjacent photovoltaic modules 7 by the medium-pressure block 3. The cable is located within the ring structure 121 and can sway slightly between the two medium-pressure block fixing devices 1 to avoid cable damage or breakage that may occur due to direct fixing. The edge pressure block fixing device 2 is fixed at the edge of the photovoltaic module 7 by the transformer block 4, and the cable is fixed by the fixing strap 5 to ensure that the cable can be stably installed at the edge and to avoid large-scale swaying or displacement of the cable due to wind or other external forces.

[0066] like Figure 8 As shown in this embodiment, when the cable is fixed along the photovoltaic module 7 by the medium pressure block fixing device 1 and the side pressure block fixing device 2, the cable passing through the annular structure 121 between adjacent medium pressure block fixing devices 1 is kept in a non-taut state, and a certain cable length is reserved between the cable fixed at the side pressure block fixing device 2 and the bracket 8, thereby effectively avoiding the problem of cable damage or breakage due to external force pulling under wind.

[0067] This utility model provides a practical cable fixing device for a flexible support in embodiment two. The device includes an edge clamping block fixing device 2 connected to an edge clamping block 4, which is used to fix photovoltaic modules 7 arranged at the edge of the flexible support. The edge clamping block fixing device 2 includes a connected edge clamping block fixing part 21 and a cable fixing part 22. The edge clamping block fixing part 21 has a second fixing hole 211 for connecting the edge clamping block fixing part 21 to the edge clamping block 4. The cable fixing part 22 includes a reserved fixing hole 221 for a fixing strap 5 to pass through and bind the cable. The usage of this edge clamping block fixing device 2 has been specifically described in embodiment one above and will not be repeated here.

[0068] The embodiments and descriptions above are merely illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed technology.
