[0002] With the increase in photovoltaic (PV) installed capacity, PV power stations have been built in most mountainous and desert areas with favorable conditions. In fishery-solar complementary projects, owners require the PV support system to have the largest possible pile spacing to minimize the impact of PV on aquaculture. Flexible PV support systems, with their large span and lightweight structure, can be well adapted to complex mountainous and fishpond projects. Therefore, developing flexible PV support systems is a key development direction and an inevitable trend in the PV industry.

[0003] However, in existing technical solutions, the installable angle of the cable connected to the node is fixed, which means that the cable can only be installed at a limited number of angles, resulting in a small adjustment range and low practicality. Furthermore, when the cable is connected to the node via a connecting component, the connecting component is not easily installed on the node. Utility Model Content

[0004] This application provides a node of a flexible photovoltaic support and a flexible photovoltaic support, aiming to solve the technical problems that the installation angle of the existing tensioning component connected to the node is relatively fixed and the adjustment range is small, and that the connecting component is not easy to install on the node when the tensioning component is connected to the node through the connecting component.

[0005] According to a first aspect of this application, one embodiment provides a node of a flexible photovoltaic support, comprising:

[0006] A first connecting component, the first connecting component being used for fixed connection with the connecting base;

[0007] The second connecting assembly includes a connector and an adjusting member. The connector is connected to the first connecting assembly.

[0012] The connector is connected between the two mounting plates and is spaced apart from the base; the adjustment member is located on the side of the connector facing the base.

[0033] In the photovoltaic industry, flexible photovoltaic (PV) brackets play a crucial role and offer significant advantages in power plant construction in complex terrain and fishpond projects. However, the installation angle of the tensioning components (also known as cables) connected to the nodes is fixed, limiting their installation to a limited number of angles. This results in a small adjustment range and low practicality. Furthermore, when the tensioning components are connected to the nodes via connecting components, the connecting components are difficult to install on the nodes.

[0034] In view of this, the present invention provides a flexible photovoltaic bracket and a node of the flexible photovoltaic bracket to expand the adjustment range of the installation angle of the tensioning component and to facilitate the installation of the connecting component of the tensioning component at the node.

[0035] like Figure 1As shown, the flexible photovoltaic support provided in this embodiment includes a node 100, a tensioning component 200, and a third connecting component 300. The third connecting component 300 connects the node 100 and the tensioning component 200; that is, the tensioning component 200 is connected to the node 100 through the third connecting component 300. It is understood that in other embodiments, the flexible photovoltaic support may not include the third connecting component 300. In this case, the tensioning component 200 can be directly connected to the node 100. The tensioning component 200 can be any one of steel wire rope, steel strand, high-strength threaded steel, and reinforcing steel.

[0036] In one embodiment, the third connecting assembly 300 includes a U-bolt 301, a connecting plate 302, and an anchor 303. The U-bolt 301 includes an arc-shaped end and a straight end disposed opposite to each other. The arc-shaped end is connected to the node 100, and the connecting plate 302 is connected to the straight end and is used for the tensioning member 200 to pass through. The anchor 303 is anchored to one end of the tensioning member 200 and is located on the side of the connecting plate 302 facing the arc-shaped end. By setting the anchor 303 on the side of the connecting plate 302 facing the arc-shaped end and anchoring it to one end of the tensioning member 200, the tensioning member 200 is fixedly connected to the third connecting assembly 300, thereby realizing the connection between the tensioning member 200 and the third connecting assembly 300.

[0037] In one embodiment, the flexible photovoltaic support also includes a connecting base (not shown), with node 100 fixedly connected to the connecting base. When the tensioning component 200 is a stay cable, the connecting base can be an end support (column or steel column) connected to the main cable, or it can be a support base set on the ground; that is, both ends of the stay cable can be connected using the node 100 disclosed in this embodiment. When the tensioning component 200 is the main cable, the connecting base can be an end support for connecting to both ends of the main cable. In specific applications, node 100 can be located on the side of the connecting base or at the bottom of the connecting base.

[0038] Please see Figure 1 and Figure 2 The node 100 of the flexible photovoltaic support provided in this embodiment includes a first connecting component 10 and a second connecting component 20. The first connecting component 10 is used for fixed connection with the connecting foundation, and the second connecting component 20 includes a connector 21 and an adjusting component 22. The connector 21 is connected to the first connecting component 10. The adjusting component 22 is used to be detachably clamped between the connector 21 and the U-bolt 301, and is rotatably connected to the connector 21 and / or the U-bolt 301. In specific applications, both the adjusting component 22 and the connector 21 are located on the inner side of the arc-shaped end of the U-bolt 301.

[0039] Using the above technical solution, the connector 21 is connected to the first connecting assembly 10, and the adjusting member 22 is detachably clamped between the connector 21 and the U-bolt 301. When installing the U-bolt 301, the adjusting member 22 can be removed in advance to increase the space around the connector 21. After the U-bolt 301 is installed in the preset position, the adjusting member 22 is then installed, improving the installation convenience of the U-bolt 301. The third connecting assembly 300, as a connecting member connecting the tensioning member 200 to the node 100, includes the U-bolt 301. Therefore, while improving the installation convenience of the U-bolt 301, the installation convenience of the third connecting assembly 300 is also improved.

[0040] The adjusting component 22 is rotatably connected to the connecting component 21 and / or the U-bolt 301. When the adjusting component 22 is rotatably connected to the connecting component 21, the adjusting component 22 rotates relative to the connecting component 21, causing the U-bolt 301 and the tensioning component 200 to rotate relative to the connecting component 21, thereby achieving a rotatable connection between the tensioning component 200 and the node 100. When the adjusting component 22 is rotatably connected to the U-bolt 301, the U-bolt 301 rotates relative to the adjusting component 22, causing the tensioning component 200 to rotate relative to the adjusting component 22, thereby achieving a rotatable connection between the tensioning component 200 and the node 100. The rotatable connection between the tensioning component 200 and the node 100 can effectively expand the adjustment range of the installation angle of the tensioning component 200 and improve the practicality of the tensioning component 200.

[0041] In another embodiment, when the flexible photovoltaic support does not have the third connecting component 300, the adjusting member 22 is detachably clamped between the connecting member 21 and the tensioning member 200, and is rotatably connected to the connecting member 21 and / or the tensioning member 200. This achieves a rotatable connection between the tensioning member 200 and the node 100.

[0042] Please see Figures 1 to 4 The adjusting member 22 includes a first side 221 and a second side 222 disposed opposite to each other. The first side 221 is used to connect the arc-shaped end of the tensioning member 200 or the U-bolt 301, and the second side 222 is used to connect the connecting member 21. The first side 221 is an arc-shaped surface. By setting the first side 221 as an arc-shaped surface, it helps the adjusting member 22 to match the arc-shaped ends of the tensioning member 200 and the U-bolt 301, and facilitates the rotational connection between the adjusting member 22 and the tensioning member 200 or the U-bolt 301. In specific applications, the center of the arc-shaped surface is set towards the second side 222.

[0043] Please see Figures 2 to 4The second side 222 has a groove 223, and part of the connector 21 is engaged in the groove 223. This helps to improve the stability of the connection between the adjusting member 22 and the connector 21. In specific applications, at least part of the outer peripheral surface of the connector 21 is designed to match the shape of the groove 223 so that part of the connector 21 can be engaged in the groove 223. Preferably, at least part of the outer peripheral surface of the connector 21 is curved, and the groove 223 is an arc-shaped groove. This allows at least part of the connector 21 to be engaged in the groove 223, and also allows for a rotatable connection between the connector 21 and the adjusting member 22.

[0044] In one embodiment, the cross-section of the adjusting member 22 is a semi-circular annular structure. The outer arc surface of the adjusting member 22 is used to connect with the arc-shaped end of the tensioning member 200 or the U-bolt 301, and the inner arc surface of the adjusting member 22 is used to connect with the connecting member 21. Of course, in other embodiments, the adjusting member 22 can also be configured with other shapes.

[0045] Please see Figure 2 The first connecting component 10 includes a base 11 and two mounting plates 12. The two mounting plates 12 are connected to the same side of the base 11 and are spaced apart from each other. The base 11 is used to be welded to the connecting foundation or integrally formed with the connecting foundation. This improves the stability of the connection between the base 11 and the connecting foundation. In specific implementations, the two mounting plates 12 can be welded to one side of the base 11 or integrally formed with the base 11.

[0046] In one embodiment, the connector 21 is connected between two mounting plates 12 and spaced apart from the base 11. The connector 21, the base 11, and the two mounting plates 12 enclose an installation space 30 for the U-bolt 301. The adjusting member 22 is located on the side of the connector 21 facing the base 11, that is, on the side of the connector 21 facing the installation space 30, so that the adjusting member 22 is sandwiched between the U-bolt 301 and the connector 21. The adjusting member 22 is detachably provided. When installing the U-bolt 301, the adjusting member 22 can be removed in advance, which can correspondingly increase the size of the installation space 30 and facilitate the installation of the U-bolt 301.

[0047] In one embodiment, the connector 21 can be any one of a connecting shaft, a bolt, or a pin. In specific applications, when the connector 21 is a connecting shaft, the connecting shaft is welded between the two mounting plates 12, or integrally formed with the two mounting plates 12, which helps to accelerate the manufacturing efficiency of the node 100. When the connector 21 is a bolt or a pin, the U-bolt 301 can be pre-installed in a preset installation position before installing the bolt or pin, further facilitating the installation of the U-bolt 301.

[0048] Please see Figure 2The first connecting assembly 10 further includes at least two reinforcing plates 13, with at least one reinforcing plate 13 between each mounting plate 12 and the base 11 on the side of the mounting plate 12 away from the other mounting plate 12. This improves the stability of the connection between the mounting plate 12 and the base 11 and increases the strength of the mounting plate 12. In this embodiment, the reinforcing plates 13 are welded between the base 11 and the mounting plates 12, and two reinforcing plates 13 are provided between each mounting plate 12 and the base 11.

[0049] Please see Figure 2 The first connecting assembly 10 also includes a stiffening plate 14, which is located at the same end of the two mounting plates 12 and connects the two mounting plates 12 to the base 11. By providing the stiffening plate 14, the stability of the connection between the mounting plates 12 and the base 11 is further improved, and the strength of the mounting plates 12 is increased. In specific applications, the stiffening plate 14 is welded between the two mounting plates 12 and the base 11.
