[0002] With the rapid development of the photovoltaic industry, flexible photovoltaic brackets suitable for complex terrain are becoming more and more widely used.

[0032] Example 1

[0033] Reference Figure 1 to Figure 3 , is the first embodiment of the utility model, which provides a four-cable connection mechanism, including:

[0034] The suspension component 100 includes a node component 101 , a four-corner component 102 adapted to be installed outside the node component 101 , and a connection component 103 adapted to be installed outside the four-corner component 102 .

[0035] Specifically, the node assembly 101 includes a connecting block 101a and an extending block 101b fixedly connected to the outside of the connecting block 101a.

[0036] Furthermore, the node assembly 101 further includes a round rod 101c fixedly connected to the outside of the extension block 101b, and a limiting ring 101d fixedly connected to the outside of the round rod 101c.

[0037] The four-corner assembly 102 includes a straight web bar 102a hinged on the outside of the round bar 101c, and an upper chord bar 102b hinged on the outside of the round bar 101c.

[0038] Preferably, the four-corner assembly 102 further includes a lower chord 102c hinged to the outside of the round rod 101c, and a diagonal web 102d hinged to the outside of the round rod 101c.

[0039] It should be noted that the connection assembly 103 includes a straight tie rod 103a hinged on the outside of the round rod 101c, and an oblique tie rod 103b hinged on the outside of the round rod 101c.

[0040] When in use, a four-cable connection unit is composed of two straight web members 102a, two diagonal web members 102d, an upper chord member 102b and a lower chord member 102c, and the nodes thereof are connected by node assemblies 101.

[0041] The connection assembly 103 is composed of a straight tie rod 103a and two staggered oblique tie rods 103b. Every two adjacent four-cable connection units can be connected through the connection assembly 103. The connection nodes of the four-corner assembly 102 and the connection assembly 103 are connected through the node assembly 101.

[0042] Multiple groups of four-cable connection units can be connected together through multiple connection components 103 to form a whole to improve stability.

[0043] At the nodes, the connecting rods of the four-corner assembly 102 and the connecting assembly 103 are hinged to the round rod 101c, and after assembly, the limiting ring 101d is fixedly connected to the outside of the outermost connecting rod to prevent the connecting rod from separating from the round rod 101c and improve stability.

[0044] One or two circular holes are provided inside the connection block 101a, so that the steel strands can pass through, so as to facilitate the connection of the steel strands with the four-cable connection mechanism.

[0045] Example 2

[0046] Reference Figure 1 to Figure 4 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a flexible photovoltaic bracket, including a four-cable connection mechanism, and,

[0047] The supporting mechanism 200 includes a side column 201 arranged outside the node assembly 101, a cable 202 adapted to be installed outside the side column 201, a flexible component 203 adapted to be installed outside the side column 201, and an auxiliary component 204 adapted to be installed outside the flexible component 203.

[0048] Specifically, the flexible component 203 includes a component installation cable 203a adapted to be installed inside the connection block 101a, a load-bearing cable 203b adapted to be installed inside the connection block 101a, and a wind-resistant cable 203c adapted to be installed inside the connection block 101a;

[0049] Among them, the component installation cable 203a, the load-bearing cable 203b and the wind-resistant cable 203c are arranged inside the side column 201.

[0050] Furthermore, the auxiliary component 204 includes a central column 204a disposed outside the component mounting cable 203a, and a crossbeam 204b fixedly connected to the top end of the central column 204a.

[0051] Furthermore, the auxiliary component 204 also includes a short column 204c fixedly connected to the top of the crossbeam 204b, and a diagonal brace 204d fixedly connected to the outside of the central column 204a;

[0052] The component installation cables 203a and the load-bearing cables 203b are arranged inside the cross beam 204b and the short column 204c.

[0053] When in use, a cable 202 is fixedly connected to the outside of the side column 201, and one end of the cable 202 is connected to the ground, thereby providing an outward pulling force for the side column 201 to prevent the side column 201 from being pulled down.

[0054] One end of the component installation cable 203a, the load-bearing cable 203b and the wind-resistant cable 203c in the flexible component 203 is connected to the side column 201, and the connection is fixed by an anchor to prevent falling off.

[0055] A circular hole is opened inside the upper connecting block 101a, and the component installation cable 203a passes through the circular hole inside the upper connecting block 101a. Two circular holes are opened inside the lower connecting block 101a, and the load-bearing cable 203b and the wind-resistant cable 203c pass through the two circular holes inside the lower connecting block 101a respectively, and an anchor is set at the position where the wind-resistant cable 203c is exposed from the lower connecting block 101a to prevent it from falling off.

[0056] When the photovoltaic panel is subjected to the upward action of negative wind load, the anti-wind cable 203c comes into play, and the connecting block 101a is used to pull the load-bearing cable 203b to control the upward displacement. When the photovoltaic panel is subjected to the downward action of positive wind load, the load-bearing cable 203b comes into play, and the four-corner component 102 is used to support the component installation cable 203a to control the downward displacement.

[0057] In some sites with heavy wind loads, during installation, a connection block 101a with two round holes may be arranged at the top, so that one end of the wind-resistant cable 203c is connected to the upper connection block 101a, thereby further enhancing the ability of the bracket to resist negative winds.

[0058] In a continuous multi-row multi-span structure, the number of wind-resistant cables 203c can be increased or decreased, and the connection position of the wind-resistant cables 203c can be changed according to the site wind pressure and the span size of the flexible photovoltaic support.

[0059] In a continuous multi-row and multi-span structure, a transverse wind-resistant anchor cable can be added to the outside of the connecting block 101a in the four-cable connecting mechanism at the mid-span position, with one end of the anchor cable connected to the connecting block 101a and the other end anchored to the ground to enhance the overall stability of the structure.

[0060] In summary, on the basis of the existing three-cable flexible photovoltaic support, this device adds a load-bearing cable 203b and a node for connecting the anti-wind cable 203c, thereby improving the bearing capacity of the cable, which not only increases the span distance of the flexible photovoltaic support, but also improves the wind resistance of the flexible photovoltaic support. It also connects multiple rows and multiple spans of continuous flexible photovoltaic support structures with transverse connecting rods and transverse anti-wind cables to form a cable truss network structure as a whole, thereby increasing the stability and safety of the flexible photovoltaic support.

[0061] Example 3

[0062] Reference Figure 1 to Figure 4 , which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides an effect description of the auxiliary component 204.

[0063] When in use, an auxiliary component 204 is added along the span direction. When the span distance is exceeded, four groups of side columns 201 are originally required to form two flexible photovoltaic bracket units. Now, due to the addition of the auxiliary component 204, only two groups of side columns 201 and one group of center columns 204a are needed to achieve the same effect, which greatly reduces the installation difficulty and material cost.

[0064] The inclination angle of the photovoltaic panel is determined by the height difference between the two component installation cables 203a, the height difference of the side column 201 is determined by the connection position of the component installation cable 203a, and the height difference of the center column 204a is determined by the height difference between the short column 204c and the beam 204b.

[0065] A diagonal brace 204d is provided between the central column 204a and the cross beam 204b to increase stability.

[0066] In summary, by setting an auxiliary component 204 between the two groups of side columns 201, the span distance of the flexible photovoltaic bracket can be increased, and by setting a short column 204c on the beam 204b, the required inclination angle can be provided for the photovoltaic panel, and by setting a diagonal support rod 204d between the central column 204a and the beam 204b, stability can be increased.
