In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0032] See also Figure 1 and Figure 2The utility model provides a photovoltaic flexible bracket, which is used to support a photovoltaic module. The photovoltaic module is connected with a steel strand 3. The photovoltaic flexible bracket includes a support assembly 1 and a connection assembly 2. The support assembly 1 includes a center column 11, a load-bearing beam 12, two support rods 13, a first rod 14 and a second rod 15. One end of the center column 11 is connected to the load-bearing beam 12. The two support rods 13 are respectively arranged on both sides of the center column 11. One end of the two support rods 13 on the same side is connected to the center column 11, and the other end of the two support rods 13 on the same side is connected to the load-bearing beam 12. The load-bearing beam 12 and the two support rods 13 form a triangular frame structure. One end of the first rod 14 is connected to the load-bearing beam 12, and the other end is connected to the support rod 13. One end of the second rod 15 is connected to the center column 11, and the other end is connected to the support rod 13.

[0033] Among them, the middle column 11 is vertically arranged, the two ends of the first rod 14 are fixedly connected to the load-bearing beam 12 and the support rod 13 respectively, the two ends of the second rod 15 are fixedly connected to the middle column 11 and the support rod 13 respectively, and further, one end of the second rod 15 facing the support rod 13 is fixedly connected to one end of the first rod 14 facing the support rod 13.

[0034] See also Figure 3 The connection assembly 2 includes a plurality of limiters 21, which are arranged along the length direction of the load-bearing beam 12 and are arranged on the side of the load-bearing beam 12 away from the center column 11, and are used to limit the position of the steel strand 3 on the load-bearing beam 12. A support assembly 1 and a connection assembly 2 form a group, and the support assembly 1 and the connection assembly 2 of the same group are arranged at one end of the photovoltaic module.

[0035] It should be noted that when both ends of the steel strand 3 are respectively connected to the limit members 21 located at both ends of the photovoltaic module, the length direction of the steel strand 3 is perpendicular to the length direction of the load-bearing beam 12, so that the steel strand 3 can stably support the photovoltaic module.

[0036] In this way, the limiter 21 on the load-bearing beam 12 can limit the position of the steel strand 3, so that multiple steel strands 3 are arranged side by side on the two load-bearing beams 12, and stably support multiple groups of photovoltaic components. The force of the load-bearing beam 12 is transmitted to the middle column 11 through the support rod 13, the first rod 14 and the second rod 15 respectively, thereby reducing the pressure on the middle column 11 while reducing the number of middle columns 11, so that the single-column and single-beam photovoltaic bracket can carry multiple groups of photovoltaic components, reduce the floor space and reduce costs.

[0037] It is understandable that the number of the limiting members 21 can be adjusted according to actual needs, and no further enumeration is given here.

[0038] See also Figure 2In some embodiments, the end of the first rod 14 away from the load beam 12 is connected to the midpoint of the support rod 13 on the same side, and the end of the second rod 15 away from the load beam 12 is connected to the midpoint of the support rod 13 on the same side. In this embodiment, the first rod 14 is located above the second rod 15, and the center column 11, the load beam 12, the support rod 13, the first rod 14 and the second rod 15 are located in the same plane.

[0039] Furthermore, two first rods 14 and two second rods 15 are provided, and one supporting rod 13 is connected to one first rod 14 and one second rod 15 respectively.

[0040] In this way, after the pressure generated by the photovoltaic module is transmitted to the load-bearing beam 12 through the steel strand 3, the pressure on the load-bearing beam 12 can be transmitted through the support rod 13, the first rod 14 and the second rod 15, reducing the pressure on the middle column 11, and providing stable support for the photovoltaic module while reducing the number of middle columns 11. In addition, since the photovoltaic module is usually arranged at an angle, the force at both ends of the load-bearing beam 12 may be different. By adjusting the setting position of the first rod 14 and the second rod 15, the overall force of the photovoltaic flexible bracket can be made more balanced; the end of the first rod 14 away from the load-bearing beam 12 and the end of the second rod 15 away from the load-bearing beam 12 are both connected to the midpoint of the support rod 13 on the same side, which can improve the stability of the photovoltaic flexible bracket when supporting the photovoltaic module.

[0041] It is understandable that the location, quantity and length of the first rod 14 and the second rod 15 can also be adjusted according to actual needs, as long as they can transfer and distribute the pressure on the load-bearing beam 12, and no further details will be given here.

[0042] See also Figure 2 In some embodiments, four limit members 21 are provided, and positions of the four limit members 21 on the load-bearing beam 12 correspond to positions of one end of the two support rods 13 facing the load-bearing beam 12 and one end of the two first rods 14 facing the load-bearing beam 12 .

[0043] In this way, the pressure from the photovoltaic components on the steel strand 3 is transmitted to the load-bearing beam 12 through the limiter 21, and the area near the limiter 21 is subjected to greater force. The limiter 21 is set at a position corresponding to the end of the support rod 13 facing the load-bearing beam 12 and the end of the first rod 14 facing the load-bearing beam 12. The pressure at the limiter 21 can be transmitted to the support rod 13 and the first rod 14, thereby reducing the pressure on the load-bearing beam 12, improving the overall strength and stability of the photovoltaic flexible bracket, and enabling the photovoltaic flexible bracket to stably support multiple groups of photovoltaic components.

[0044] It is understandable that the position of the limiting member 21 is not limited to the position corresponding to the support rod 13 and the first rod 14 , and the number and setting position of the limiting member 21 can also be adjusted according to actual needs.

[0045] See also Figure 3 and Figure 4 In some embodiments, the connection assembly 2 also includes a plurality of connection plates 22, the connection plates 22 are arranged on the side of the load-bearing beam 12 away from the center column 11, the limiter 21 is connected to the connection plates 22, and the connection plates 22 are provided with limit grooves 221 for limiting the position of the steel strands 3.

[0046] In this embodiment, one limiting member 21 is connected to a corresponding connecting plate 22 , the connecting plate 22 is fixedly connected to the load-bearing beam 12 , the limiting groove 221 is a semicircular groove, and the length direction of the limiting groove 221 is perpendicular to the length direction of the load-bearing beam 12 .

[0047] In this way, the steel strand 3 is inserted into the limiting groove 221 and limited by the limiting member 21, so that the relative position of the steel strand 3 and the load-bearing beam 12 can be fixed, making it difficult for the steel strand 3 to deviate and fall off, causing the photovoltaic component to fall off the photovoltaic flexible bracket, thereby improving the load-bearing stability of the photovoltaic bracket.

[0048] See also Figure 3 and Figure 4 In some embodiments, the limiting member 21 is a U-shaped bolt, which passes through the load-bearing beam 12 and is detachably connected to the load-bearing beam 12. Furthermore, the connecting plate 22 is provided with a plurality of limiting holes 222 for the U-shaped bolts to pass through.

[0049] Among them, the load-bearing beam 12 is a hollow beam structure, and the two ends of the U-shaped bolt are respectively inserted into the inside of the load-bearing beam 12, so that the bending part of the U-shaped bolt and the limiting groove 221 work together to limit the steel strand 3; nuts are connected to the two ends of the U-shaped bolt to limit the position of the U-shaped bolt; two rows of limiting holes 222 are correspondingly opened on a connecting plate 22.

[0050] In this way, after the steel strand 3 is inserted into the limiting groove 221, the bent portion of the U-bolt is sleeved on the steel strand 3, so that the steel strand 3 is limited by the U-bolt, and then the nut is screwed into the end of the U-bolt to fix the U-bolt on the load-bearing beam 12, which can stably limit the position of the steel strand 3 on the load-bearing beam 12. By setting multiple rows of limiting holes 222, the number and installation position of the U-bolts can be adjusted, making the U-bolt more flexible in limiting the steel strand 3.

[0051] See also Figure 2 In some embodiments, the center column 11 is connected to a mounting member 111, and one end of the support rod 13 facing the center column 11 and one end of the second rod 15 facing the center column 11 are both connected to the mounting member 111. Further, the mounting member 111 is a clamp.

[0052] In this embodiment, two hoops are provided, both of which are sleeved on the center column 11, and one end of the support rod 13 facing the center column 11 and one end of the second rod 15 facing the center column 11 are respectively connected to the two hoops by bolts.

[0053] In this way, the support rod 13 and the second rod 15 are connected to the middle column 11 through the clamp, and the clamp can be installed at the corresponding position on the middle column 11 according to the position of the support rod 13 and the second rod 15, thereby improving the installation flexibility and facilitating adaptation to support rods 13 and the second rod 15 at different angles to support photovoltaic components at different angles.

[0054] It is understandable that the number and location of the hoops can be adjusted according to actual needs and the number of support rods 13 and the number of second rods 15 , so as to connect the support rods 13 and the second rods 15 to the center column 11 .

[0055] See also Figure 2 In some embodiments, the support assembly 1 further includes an auxiliary rod 112, the two ends of which are respectively connected to the middle column 11 and the load-bearing beam 12, and the auxiliary rod 112 is tilted toward one end of the load-bearing beam 12. In this embodiment, the two ends of the auxiliary rod 112 are respectively fixedly connected to the middle column 11 and the load-bearing beam 12.

[0056] In this way, the end face angle of the auxiliary rod 112 away from the load-bearing beam 12 is the angle of the load-bearing beam 12, that is, the angle of the photovoltaic component. By controlling the angle of the auxiliary rod 112 away from the end face of the load-bearing beam 12, the photovoltaic flexible bracket can support photovoltaic components at different angles.

[0057] It is understandable that the auxiliary rod 112 can also be detachably connected to the middle column 11 by bolts, and is not limited to a fixed connection. By replacing the auxiliary rod 112 at different angles, the auxiliary rod 112 can stably support photovoltaic components at different angles, thereby improving the flexibility of the photovoltaic flexible bracket. The connection method between the auxiliary rod 112 and the middle column 11 can be adjusted according to actual needs, and no further examples are given here.

[0058] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
