Description

Technical Field

[0001] This utility model relates to the field of flexible photovoltaic technology, and more specifically, to a flexible photovoltaic wind-resistant support and a flexible photovoltaic system. Background Technology

[0002] With the rapid development of the photovoltaic industry, flexible photovoltaic (PV) systems have emerged to adapt to various complex terrains such as mountains and fishponds. Flexible PV systems directly support the photovoltaic modules via two main cables. Support structures constrain the main cables and provide tensioning conditions for prestressing. To support the PV modules, the main cables of flexible PV systems are typically arranged in parallel, forming a planar structure. Planar structures generally have poor stiffness and stability, so wind-resistant supports are usually installed. The main function of these wind-resistant supports is to rigidly connect the main cables to the stabilizing cables, forming a spatial structure with better overall integrity and stability. This prevents structural damage and microcracks in the modules when the flexible PV system is subjected to wind loads, snow loads, and gravity loads. In existing technologies, wind-resistant supports are planar trusses, which have poor stability and insufficient load-bearing capacity, making the PV modules prone to microcracks and overturning.

[0003] Therefore, how to reduce the risk of microcracks and flipping in photovoltaic modules has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a flexible photovoltaic wind-resistant support to reduce the risk of photovoltaic modules developing hidden cracks and overturning.

[0005] Another core aspect of this utility model is the disclosure of a flexible photovoltaic system including the aforementioned flexible photovoltaic wind-resistant support.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A flexible photovoltaic wind-resistant support system includes:

[0009] The chassis and the bending diagonal braces of each flat frame are detachably connected to the chassis;

[0010] The crossbars are connected at both ends of at least two oppositely arranged planar frames, so that each planar frame and each crossbar forms a quadrangular pyramid structure. The straight members and crossbars form the base of the quadrangular pyramid structure. The crossbars are detachably connected to the planar frames through member connectors. The crossbars are equipped with cable connectors that can connect to the main cable.

The first end of the support rod is connected to the crossbar of one of the flexible photovoltaic wind-resistant supports, and the second end is connected to the ear plates of the adjacent row of flexible photovoltaic wind-resistant supports.

[0015] Optionally, in the above-mentioned flexible photovoltaic wind-resistant support, the crossbar includes a straight bar portion and bent portions located at both ends of the straight bar portion. The bent portions at the same end of two parallel crossbars extend in a direction that approaches each other, and the first end of the support rod is connected to the bent portion.

[0016] Optionally, in the above-mentioned flexible photovoltaic wind-resistant support, the bent diagonal bar is detachably connected to the connecting part through a U-shaped connector;

[0017] The U-shaped connector includes a second base plate and side plates disposed at both ends of the second base plate. The U-shaped connector is wrapped around the bent diagonal bar.

[0018] Optionally, in the above-mentioned flexible photovoltaic wind-resistant support system, the bent diagonal brace is integrally formed; and / or,

[0019] The chassis is integrally molded; and / or,

[0020] The crossbar is formed in one piece.

[0021] A flexible photovoltaic system includes a support frame, a main cable, a stabilizing cable, and a wind-resistant support frame. The support frame is installed on the ground, the main cable is installed on the support frame, and the photovoltaic modules are laid on the main cable.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] like Figures 1-2 As shown in the figure, this utility model embodiment discloses a flexible photovoltaic wind-resistant support, including a planar frame 10, a chassis 20, and a crossbar 30.

[0046] The system comprises at least two planar frames 10, each arranged at an angle. Each planar frame 10 includes a V-shaped bent diagonal bar 11 and a straight bar 12, with the straight bar 12 detachably connected to both ends of the bent diagonal bar 11. The bent diagonal bars 11 of each planar frame 10 are detachably connected to the chassis 20. The ends of at least two opposing planar frames 10 are connected by crossbars 30, forming a quadrangular pyramid structure. The straight bar 12 and the crossbars 30 form the base of the quadrangular pyramid structure, and the surfaces containing the bent diagonal bars 11 form the sides of the quadrangular pyramid structure. The chassis 20 and the crossbars 30 connect the planar frames 10 into a single unit.

[0047] Specifically, the crossbar 30 is detachably connected to the plane frame 10 via a member connector 40, and the crossbar 30 is equipped with a cable connector 200 capable of connecting to the main cable 100. Specifically, such as... Figure 7 As shown, the extension direction of the main cable 100 is the same as the extension direction of the straight rod 12, and the photovoltaic modules are laid on the main cable 100 in an array.

[0048] The flexible photovoltaic wind-resistant support disclosed in this embodiment is formed by combining multiple planar frames 10 to form a spatial structure, which is more stable than a planar frame. The wind-resistant support is a four-corner pyramid structure, which can decompose vertical wind pressure into forces in multiple directions. Compared with a planar frame, it can destroy the formation of wind vortices, effectively resist wind blowing, and improve the wind resistance of the flexible photovoltaic system. At the same time, the spatial structure can reduce the possibility of structural damage when resisting wind loads, snow loads, and gravity loads, reduce the risk of photovoltaic modules developing hidden cracks and overturning, and ensure the stable operation of photovoltaic modules. The planar frame 10, the chassis 20, and the crossbar 30 are detachably connected, making installation convenient and transportation easy. The setting of the rod connector 40 facilitates the connection between the planar frame 10 and the crossbar 30, which can improve installation efficiency.

[0049] Furthermore, such as Figure 1 and Figure 2 As shown, the number of planar frames 10 preferably includes two, and the number of crossbars 30 preferably includes two arranged in parallel.

[0050] Furthermore, such as Figure 1As shown, at least one of the bent diagonal bar 11 and the straight bar 12 is detachably connected to the bar connector 40. Specifically, the straight bar 12 and the bent diagonal bar 11 can be connected by bolts and nuts, clamps, plugs, or snap-fit ​​connections; at least one of the straight bar 12 and the bent diagonal bar 11 is detachably connected to the bar connector 40, specifically by bolts and nuts or snap-fit ​​connections; the crossbar 30 is connected to the bar connector 40, specifically by bolts and nuts or snap-fit ​​connections, and the specific connection method can be selected according to the actual situation. Specifically, as... Figure 3 As shown, the bent diagonal bar 11 includes a bent diagonal bar body 111 and extensions 112 located at both ends of the bent diagonal bar body 111. The extensions 112 are preferably formed by bending the bent diagonal bar body 111. The extension direction of the extensions 112 is the same as the extension direction of the straight bar 12 to facilitate connection and assembly. To improve the strength of the connection and structural stability, both the straight bar 12 and the bent diagonal bar 11 are connected to the bar connector 40.

[0051] Furthermore, such as Figure 2 and Figure 5 As shown, the rod connector 40 includes a first base plate 41 and wing plates 42 disposed on both sides of the first base plate 41, forming an overall U-shaped structure. The crossbar 30 is detachably connected to the first base plate 41. The bent diagonal bar 11 and the straight bar 12 are located between the two wing plates 42 and are detachably connected to the wing plates 42 respectively. The figure illustrates the connection via bolts and nuts as an example. The bent diagonal bar 11 and the straight bar 12 are connected by bolts and nuts, and then connected to the wing plates 42 respectively by bolts and nuts. The rod connector 40 encloses the bent diagonal bar 11 and the wing plates 42, which improves the connection's strength and the structural stability of the flexible photovoltaic wind-resistant support, while also facilitating the connection and assembly with the crossbar 30. Preferably, the rod connector 40 is integrally bent from sheet metal, and the U-shaped structure design facilitates processing.

[0052] Furthermore, such as Figure 5 and Figure 6 As shown, the chassis 20 includes a chassis body 21 and connecting portions 22 arranged obliquely on both sides of the chassis body 21. The bent diagonal rod 11 is detachably connected to the connecting portion 22, which can be connected by bolts and nuts or by clips. The chassis body 21 is provided with cable connectors 200 that can connect the stabilizing cable 300 and the ground anchor cable. The chassis body 21 is designed to facilitate the connection of the stabilizing cable 300 and the ground anchor cable, and the connecting portions 22 are designed to facilitate the connection of the bent diagonal rod 11 of the plane frame 10, ensuring that the connection of the plane frame 10 and the connection of the stabilizing cable 300 and the ground anchor cable do not interfere with each other.

[0053] Furthermore, such as Figures 3-5As shown, the chassis 20 also includes ear plates 23 disposed at both ends of the connecting portion 22, which can connect to the support rods 400. Each chassis 20 includes at least two ear plates 23, preferably four ear plates 23, each ear plate 23 being disposed at both ends of each connecting portion 22. In a flexible photovoltaic system, the flexible photovoltaic supports are usually arranged in multiple rows. In order to connect the rows of flexible photovoltaic supports into a whole, adjacent rows of flexible photovoltaic wind-resistant supports are connected by support rods 400. Specifically, the first end of the strut 400 is connected to the crossbar 30 of one of the flexible photovoltaic wind-resistant supports, and the second end is connected to the ear plate 23 of the adjacent row of flexible photovoltaic wind-resistant supports. Preferably, there are two struts 400 connecting the adjacent rows of flexible photovoltaic wind-resistant supports, and the two struts 400 form a V-shaped structure. The struts 400 connect the multiple rows of flexible photovoltaic supports into a whole, dispersing the wind pressure borne by a single row of flexible photovoltaic supports to multiple rows, avoiding local overload, improving the wind resistance of the flexible photovoltaic supports, and further reducing the possibility of microcracks and overturning of photovoltaic modules.

[0054] Preferably, the chassis 20 is formed by bending sheet metal in one piece. The one-piece forming method can ensure the strength and structural stability of the chassis 20, while making the assembly simpler and reducing the assembly difficulty.

[0055] Furthermore, such as Figure 2 and Figure 5 As shown, to accommodate the connection of the strut 400, the crossbar 30 includes a straight section 31 and bent sections 32 located at both ends of the straight section 31. The bent sections 32 at the same end of the two parallel crossbars 30 extend in a direction that brings them closer to each other. The first end of the strut 400 is connected to the bent section 32 of the crossbar 30, preferably by a detachable connection method, such as a bolt and nut connection, a snap-fit ​​connection, or a clamp connection.

[0056] Furthermore, to enhance connection strength and stability, such as Figure 1 and Figure 6 As shown, the bent diagonal bar 11 is detachably connected to the connecting part 22 via a U-shaped connector 50, preferably by bolts and nuts. The U-shaped connector 50 includes a second base plate 51 and side plates 52 disposed at both ends of the second base plate 51. The U-shaped connector 50 covers the bent diagonal bar 11, and bolts pass through through holes formed in the U-shaped connector 50, the bent diagonal bar 11, and the connecting part 22, and are threadedly connected to nuts. The U-shaped connector 50 can disperse stress concentration, provide a rigid support surface, improve connection strength, and protect the bent diagonal bar 11. The U-shaped connector 50 is preferably integrally formed to ensure structural strength and stability.

[0057] Furthermore, in order to improve the strength and stability of the bent diagonal bar 11, the chassis 20 and the crossbar 30 and reduce the complexity of assembly, the bent diagonal bar 11 is preferably formed by integral bending of a square tube, and / or the chassis 20 is formed by integral bending of a sheet metal part, and / or the crossbar 30 is formed by integral bending of a square tube.

[0058] Furthermore, such as Figure 1 As shown, the cable connector 200 includes a toothed bracket, a U-bolt, and a locking nut. Taking the connection of the cable connector 200 to the main cable 100 as an example, the U-bolt passes through the through holes opened on the toothed bracket and the crossbar 30 and is threadedly engaged with the locking nut. A space is formed between the U-bolt and the toothed bracket for the main cable 100 to pass through. The cable connectors 200 of the stabilizing cable 300 and the ground anchor cable have the same structure, which will not be described in detail.

[0059] Furthermore, such as Figure 7 As shown in the figure, this utility model embodiment also discloses a flexible photovoltaic system, including a support 600, a main cable 100, a stabilizing cable 300, and a wind-resistant support 700. The support 600 is set on the ground, the main cable 100 is set on the support 600, and the photovoltaic modules are laid on the main cable 100. The extension direction of the main cable 100 is the same as the extension direction of the straight rod 12, and the extension direction of the stabilizing cable 300 is the same as the extension direction of the main cable 100. The wind-resistant support 700 is set between the main cable 100 and the stabilizing cable 300, and the wind-resistant support 700 is the flexible photovoltaic wind-resistant support of the above embodiment. Specifically, the main cable 100 is connected to the crossbar 30 of the wind-resistant support 700, and the stabilizing cable 300 is connected to the base 20 of the support 600 and the wind-resistant support 700.

[0060] Furthermore, flexible photovoltaic systems typically include multiple rows of flexible photovoltaic supports. To connect these rows of supports into a single unit, they also include struts 400 and inter-row wind-resistant cables 500. Specifically, the first end of the inter-row wind-resistant cable 500 connects to one of the supports 600, preferably the nearest support 600, and the second end connects to the wind-resistant support 700 of the adjacent row of flexible photovoltaic supports. The first end of the strut 400 connects to the crossbar 30 of one of the wind-resistant supports 700, and the second end connects to the base 20 of the adjacent row of wind-resistant supports 700. To further enhance wind resistance, each wind-resistant support 700 is preferably connected to two inter-row wind-resistant cables 500 and two struts 400. The struts 400 and inter-row wind-resistant cables 500 are preferably connected to the wind-resistant supports 700 using U-bolts and nuts, specifically to the bent portion 32 of the crossbar 30 of the wind-resistant support 700, where the crossbar 30 has corresponding mounting holes.

[0061] Figure 7The flexible photovoltaic support shown includes four rows, with each row equipped with four wind-resistant supports 700. Taking the first row (topmost) and the second row of flexible photovoltaic support as examples, and the rightmost wind-resistant support 700 as an example, the connection between the support rod 400 and the inter-row wind-resistant cable 500 is explained. The first end of the support rod 400 is connected to the crossbar 30 of the wind-resistant support 700 of the first row of flexible photovoltaic support, and the second end is connected to the base 20 of the wind-resistant support 700 of the second row of flexible photovoltaic support.
