[0043] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, the flexible support structure 10 involved in the embodiment of the present application is applied to an inland floating photovoltaic system. The inland floating photovoltaic system includes a floating tube assembly 20 . The flexible support structure 10 includes: a flexible support assembly 100 and a first tensioning assembly 200 .

[0044] Specifically, the first tensioning assembly 200 includes a first tensioning member 210 and at least one second tensioning member 220, the first tensioning member 210 is fixedly connected to the floating tube assembly 20, the first tensioning member 210 is provided with a first connecting through hole 211, and the first tensioning member 210 has a first limiting end face 212, the first limiting end face 212 is located at the edge of one end of the first connecting through hole 211 away from the middle of the flexible support assembly 100, one end of the flexible support assembly 100 is penetrated through the first connecting through hole 211, and at least partially exposed outside the first connecting through hole 211, the second tensioning member 220 is fixedly connected to the part of the flexible support assembly 100 exposed outside the first connecting through hole 211, and the connection position of the second tensioning member 220 on the flexible support assembly 100 is adjustable; wherein, the second tensioning member 220 is located at one end of the first tensioning member 210 away from the middle of the flexible support assembly 100, and one of the second tensioning members 220 is against the first limiting end face 212.

[0045] In the above-mentioned flexible support structure 10, the first tensioning member 210 can be fixed by the floating tube assembly 20, and the flexible support assembly 100 can be fixed by the first tensioning member 210. In this process, when the flexible support assembly 100 is fixedly connected to the first tensioning member 210, the flexible support assembly 100 has a tendency to move toward the middle of the flexible support assembly 100. Since at least one second tensioning member 220 is fixedly connected to the portion of the flexible support assembly 100 exposed outside the first connecting through hole 211, the second tensioning member 220 is located at one end of the first tensioning member 210 away from the middle of the flexible support assembly 100, and one of the second tensioning members 220 is connected to the first limit The end faces 212 abut against each other, so the second tensioning member 220 can provide the flexible support assembly 100 with a force to resist the movement of the flexible support assembly 100 toward its middle through the fixed connection between the second tensioning member 220 and the flexible support assembly 100 and the abutment with the first limiting end face 212, so as to achieve tensioning of the flexible support assembly 100. At the same time, since the connection position of the second tensioning member 220 on the flexible support assembly 100 is adjustable, the connection position of the flexible support assembly 100 and the first tensioning member 210 can be adjusted by adjusting the connection position of the second tensioning member 220 on the flexible support assembly 100, so as to adjust the tension of the flexible support assembly 100.

[0046] Reference Figure 4 As shown, the flexible bracket assembly 100 includes a flexible bracket 110 and a first connecting shaft 120. The flexible bracket 110 is fixedly connected to one end of the first connecting shaft 120. The end of the first connecting shaft 120 away from the flexible bracket 110 is passed through the first connecting through hole 211. The second tensioning member 220 is fixedly connected to the first connecting shaft 120.

[0047] It can be understood that the first connecting shaft 120 can be fixed by the first tensioning member 210, so as to further fix the flexible bracket 110 connected to the first connecting shaft 120. In this process, the first connecting shaft 120 can be inserted into the first connecting through hole 211. At the same time, the second tensioning member 220 is fixedly connected to the part of the first connecting shaft 120 exposed outside the first connecting through hole 211, and the second tensioning member 220 is abutted against the first limiting end face 212, so that the first connecting shaft 120 can be fixed on the first tensioning member 210. Furthermore, the connection position of the second tensioning member 220 on the first connecting shaft 120 can be adjusted to adjust the connection position of the first connecting shaft 120 and the first tensioning member 210, so as to adjust the tension of the flexible bracket assembly 100.

[0048] Reference Figure 2 as well as Figure 4As shown, the end of the first connecting shaft 120 away from the flexible bracket 110 has a first external thread, and the first external thread is at least partially located outside the first connecting through hole 211. The second tensioning member 220 is a first-first connecting sleeve, and the first-first connecting sleeve has a first internal thread. The first-first connecting sleeve is sleeved on the first connecting shaft 120, and the first external thread is threadably connected to the first internal thread.

[0049] It can be understood that the fixed connection between the first connecting sleeve and the first connecting shaft 120 can be achieved by the threaded connection between the first external thread and the first internal thread. At the same time, the connection position of the first connecting sleeve on the first connecting shaft 120 can be adjusted by rotating the first connecting sleeve on the first connecting shaft 120, so as to adjust the connection position of the first connecting shaft 120 and the first tensioning member 210, thereby adjusting the tension of the flexible bracket assembly 100.

[0050] Continue to refer to Figure 2 as well as Figure 4 As shown, there are multiple first connecting sleeves, each of which is sleeved on the first connecting shaft 120, and the first internal thread of each first connecting sleeve is threadedly connected to the first external thread of the first connecting shaft 120, the end faces of the multiple first connecting sleeves are against each other, and one of the end faces of one of the first connecting sleeves is against the first limit end face 212.

[0051] It can be understood that the connection position of each first connecting sleeve on the first connecting shaft 120 can be adjusted by rotating each first connecting sleeve on the first connecting shaft 120. At the same time, since one of the end faces of one of the first connecting sleeves abuts against the first limiting end face 212, the first connecting sleeve can provide the flexible bracket 110 with a force to resist the movement of the flexible bracket 110 toward its middle, so that the flexible bracket 110 can be tensioned. At the same time, since the end faces of multiple first connecting sleeves abut against each other, the structural stability of the first connecting sleeve abutting against the first limiting end face 212 can be enhanced by multiple first connecting sleeves, and the first connecting sleeve abutting against the first limiting end face 212 can be avoided from moving along the axial direction of the flexible bracket 110, thereby ensuring the tension of the flexible bracket 110.

[0052] Specifically, in the above-mentioned embodiment, the total length of the first external thread is greater than the total length of each first internal thread, so as to ensure that the plurality of first connecting sleeves are all threadedly connected to the first connecting shaft 120 .

[0053] Continue to refer to Figure 2 as well as Figure 4As shown, the flexible support structure 10 further includes a first connecting component 300 , one end of the first connecting component 300 is fixedly connected to one end of the flexible support 110 , and the other end of the first connecting component 300 is fixedly connected to the first connecting shaft 120 .

[0054] It is understandable that the first connecting shaft 120 can be connected to the flexible bracket 110 through the first connecting assembly 300 , so that the tension of the flexible bracket 110 can be adjusted by changing the connection position between the first connecting shaft 120 and the first tensioning member 210 .

[0055] Reference Figure 4 as well as Figure 6 As shown, the first connecting component 300 includes a first connecting member 310 and at least one second connecting member 320. The first connecting member 310 is provided with a first cylindrical hole 311 and a first conical hole 312 connected to the first cylindrical hole 311. The first connecting shaft 120 is passed through the first cylindrical hole 311 at one end close to the flexible bracket 110, and is fixedly connected to the part of the first connecting member 310 corresponding to the first cylindrical hole 311. One end of the flexible bracket 110 is passed through the first conical hole 312, and at least one second connecting member 320 is embedded between the flexible bracket 110 and the hole wall of the first conical hole 312, and is against the outer wall of the flexible bracket 110 and the hole wall of the first conical hole 312.

[0056] It can be understood that the first connecting shaft 120 and the first connecting member 310 can be fixedly connected through the first cylindrical hole 311. At the same time, since at least one second connecting member 320 is embedded between the flexible bracket 110 and the hole wall of the first conical hole 312, and abuts against the outer wall of the flexible bracket 110 and the hole wall of the first conical hole 312, the flexible bracket 110 can be fixedly connected to the part of the first connecting member 310 corresponding to the first conical hole 312, so that the first connecting shaft 120 and the flexible bracket 110 can be fixedly connected through the first connecting assembly 300.

[0057] Continue to refer to Figure 4 as well as Figure 6 As shown, the hole wall of the first cylindrical hole 311 has a second internal thread, and the end of the first connecting shaft 120 close to the flexible bracket 110 has a second external thread, and the second internal thread is threadedly connected with the second external thread.

[0058] It is understandable that the fixed connection between the first connecting shaft 120 and the first connecting member 310 can be achieved through the threaded connection between the second internal thread and the second external thread.

[0059] Reference Figure 4As shown, there are multiple second connecting members 320, each of which is embedded between the flexible bracket 110 and the hole wall of the first conical hole 312, and multiple second connecting members 320 are arranged around the flexible bracket 110 to fill the space between the flexible bracket 110 and the hole wall of the first conical hole 312.

[0060] It can be understood that since the multiple second connecting members 320 are arranged around the flexible bracket 110 to fill the space between the flexible bracket 110 and the hole wall of the first conical hole 312, the multiple second connecting members 320 can squeeze the end of the flexible bracket 110 passing through the first conical hole 312 so that the flexible bracket 110 can be fixed between the multiple second connecting members 320. In this process, when the flexible bracket 110 is passed through the first conical hole 312, the flexible bracket 110 will have a tendency to move toward its middle due to its own elastic potential energy, that is, the flexible bracket 110 has a tendency to move toward the cone top of the first conical hole 312. At this time, the squeezing force of the multiple second connecting members 320 on the flexible bracket 110 can be gradually increased, thereby improving the fixing effect on the flexible bracket 110, thereby improving the stability of the connection structure between the flexible bracket 110 and the first connecting member 310, and further realizing the fixed connection between the flexible bracket 110 and the first connecting shaft 120.

[0061] Specifically, refer to Figure 8 As shown, in the above embodiment, there are two second connectors 320, each of which is a part of the cone structure, and the two second connectors 320 are connected end to end to form a cone structure, and the outer wall of the cone structure is in contact with the inner wall of the first cone hole 312, and the interior of the cone structure is provided with a first avoidance hole 330 for the flexible bracket 110 to pass through, so as to achieve the squeezing and fixing of the flexible bracket 110 through the abutment between the hole wall of the first avoidance hole 330 and the outer wall of the flexible bracket 110. Of course, in addition to this, in other embodiments, the second connectors 320 can also be three, four, five, etc., and multiple second connectors 320 are connected end to end to form the cone structure.

[0062] More specifically, in the above-mentioned embodiment, the first avoidance hole 330 is provided with a third internal thread, the outer surface of the flexible bracket 110 passing through the first avoidance hole 330 has a third external thread, and the third internal thread is threadedly connected to the third external thread, so as to further improve the connection structure stability between the flexible bracket 110 and the multiple second connecting members 320.

[0063] Reference Figure 6 As shown, the diameter of the first cylindrical hole 311 is R 1 , the cone bottom diameter of the first conical hole 312 is R 2 , satisfying: R 1 ≥R2 .

[0064] It can be understood that when the aperture R of the first cylindrical hole 311 is 1 The cone bottom diameter R of the first cone hole 312 2 Satisfaction: R 1 ≥R 2 When the second connecting member 320 is inserted into the first cylindrical hole 311 and enters the first conical hole 312 , the second connecting member 320 can be embedded between the flexible bracket 110 and the hole wall of the first conical hole 312 .
