[0044] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, merely for explaining the present application, and cannot be understood as limiting the present application.

[0045] Reference is made below to Figures 1-7 The photovoltaic support system 100 according to embodiments of the present application is described below, which is used for mounting the photovoltaic assembly 200 to provide a mounting carrier for the photovoltaic assembly 200, and to suspend the photovoltaic assembly 200 in the air to improve the light effect at the photovoltaic assembly 200.

[0046] The photovoltaic support system 100 according to embodiments of the present application comprises the end support 1, the intermediate support 2 and the stay cable assembly 3.

[0047] Referring to Figure 3 , the mounting support comprises two end supports 1 arranged at intervals along a first direction, and the stay cable assembly 3 is connected to the two end supports 1 at both ends of the first direction. Meanwhile, at least one intermediate support 2 is arranged between the two end supports 1, and the stay cable assembly 3 can continuously extend through the intermediate support 2 and be supported by the intermediate support 2 to improve the installation reliability and load bearing capacity of the stay cable assembly 3 through the intermediate support 2.

[0048] The above-mentioned "continuously extending through" means that the stay cable assembly 3 can be arranged from the passing structure through the intermediate support 2, that is, the stay cable assembly 3 connected between the two end supports 1 is a continuously extending stay cable, rather than a multi-segment spliced stay cable structure.

[0049] The cable assembly 3 is connected to the two end supports 1 at both ends of the cable assembly 3 in the first direction, and the middle region of the cable assembly 3 (i.e. the part between the two end supports 1) can be supported on the intermediate support 2 to improve the load-carrying capacity of the cable assembly 3.

[0050] It should be noted that the photovoltaic assembly 200 is installed on the cable assembly 3 to provide an installation carrier for the photovoltaic assembly 200 through the cable assembly 3. The cable assembly 3 is a flexible structure, so that the cable assembly 3 has good structural strength to meet the assembly requirements of the photovoltaic assembly 200, and the cable support assembly has the characteristics of flexible support, which can better resist the influence of external factors on the photovoltaic support system 100.

[0051] At present, the prestressed cable photovoltaic support system 100 can realize high clearance and large span across the photovoltaic land field area, so as to reasonably utilize the land, realize land saving and space utilization, and improve the value of the land. In the related art, the installation structure in the prestressed cable photovoltaic support system 100 is complex, and an anchor device needs to be arranged at the intermediate support 2 to realize cable turning and anchoring, so that the number of components (such as cable lock heads and anchor devices) in the prestressed cable photovoltaic system 100 is large, the assembly is difficult, and the cost is high.

[0052] In the present application, the cable assembly 3 is only connected to the installation support and is supported by the intermediate support 2 to realize the installation of the cable assembly 3, so that the number of installation components required in the photovoltaic support system 100 can be reduced while meeting the installation and support requirements of the photovoltaic assembly 200, and the construction difficulty of the photovoltaic support system 100 is reduced.

[0053] As shown in Figure 3 In some embodiments of the present application, the cable assembly 3 is provided with a plurality of cable support units 301, and the plurality of cable support units 301 are arranged along the first direction. The end support 1 and the intermediate support 2 arranged adjacent thereto are provided with one cable support unit 301.

[0054] It can be understood that the demarcation point of the cable support unit 301 is the intermediate support 2, and the intermediate support 2 can support the cable assembly 3 to improve the load-carrying capacity and structural strength of each cable support unit 301. Therefore, one cable support unit 301 is arranged between the end support 1 and the intermediate support 2 arranged adjacent thereto in the first direction.

[0055] As shown in Figure 3As shown, in further embodiments of the present application, the intermediate support 2 is in plurality, and the plurality of intermediate supports 2 are arranged between the two end supports 1 and are spaced apart along the first direction to support the cable assembly 3 respectively by the plurality of intermediate supports 2, thereby improving the installation stability and reliability of the cable assembly 3.

[0056] Wherein, since the demarcation point of the cable support unit 301 is the intermediate support 2, when the plurality of intermediate supports 2 are arranged between the two end supports 1, one cable support unit 301 is arranged between two intermediate supports 2 arranged adjacent to each other in the first direction. That is, the plurality of cable support units 301 described above can be arranged between the end support 1 and the intermediate support 2 arranged adjacent thereto, and between two intermediate supports 2 arranged adjacent to each other in the first direction.

[0057] It can be understood that the photovoltaic support system 100 is applied to a photovoltaic field area with sufficient east-west length, and the cable assembly 3 is a support structure with flexibility. In order to ensure the structural strength and support stability of the cable assembly 3, the length of the cable support unit 301 needs to be designed, so that a plurality of intermediate supports 2 can be arranged between two end supports 1 arranged opposite to each other in the first direction, to provide a plurality of support structures for the cable assembly 3, and a plurality of cable support units 301 can be formed along the first direction in sequence by the plurality of intermediate supports 2 at the cable assembly 3, thereby facilitating the unitization and modularization design arrangement of the photovoltaic support system 100.

[0058] In some embodiments of the present application, the cable assembly 3 comprises: a mounting cable 31, a stabilizing cable 32, and a bearing cable 33.

[0059] Wherein, the mounting cable 31 is connected between the two end supports 1, and the mounting cable 31 is used to mount the photovoltaic module 200, and the mounting cable 31 forms a plurality of mounting sections 311 arranged in sequence along the first direction; the stabilizing cable 32 is connected between the two end supports 1 and passes through the intermediate support 2, and the stabilizing cable 32 forms a plurality of stabilizing sections 321 arranged in sequence along the first direction; and the bearing cable 33 is connected between the two end supports 1 and passes through the intermediate support 2, and the bearing cable 33 forms a plurality of bearing sections 331 arranged in sequence along the first direction.

[0060] Thus, the cable assembly 3 can provide installation support structure for the photovoltaic module 200 while having good stability and bearing performance. Wherein, one group of mounting sections 311, stabilizing sections 321, and bearing sections 331 constitute one of the above-described cable support units 301.

[0061] It should be noted that the boundaries of the plurality of cable support units 301 are at the intermediate supports 2, and the same group of installation segments 311, stabilizing segments 321 and load-bearing segments 331 refer to the portions of the installation cable 31, the stabilizing cable 32 and the load-bearing cable 33 located between two intermediate supports 2 arranged adjacent to each other in the first direction, between the end support 1 and the intermediate support 2 arranged adjacent thereto.

[0062] In combination Figure 5 and Figure 6 , the end of the installation cable 31 is connected to the end support 1, and the installation cable 31 passes through the intermediate support 2 from above the intermediate support 2, that is, the installation cable 31 can be lapped at the upper end face of the intermediate support 2, so that the intermediate support 2 can support the installation cable 31, improve the load-bearing support effect of the installation cable 31 on the photovoltaic module 200, and ensure the installation stability and reliability of the photovoltaic module 200.

[0063] It can be understood that when the photovoltaic module 200 is installed on the installation cable 31, the gravity of the photovoltaic module 200 will act on the installation cable 31, and the installation cable 31 can be lapped and supported on the intermediate support 2. At the same time, the tension and cable force of the installation cable 31 can be adjusted through the tensioning setting of the installation support.

[0065] As shown in Figure 3 , in some embodiments of the present application, the load-bearing segment 331 is configured as an arc-shaped segment with the opening open upward, so as to improve the load-bearing performance of the cable support unit 301 through the load-bearing segment 331, thereby improving the load-bearing capacity of the cable support unit 301 on the photovoltaic module 200.

[0066] It should be noted that the load-bearing segment 331 can be configured as an arc-shaped segment with the opening open upward while the stabilizing segment 321 is configured as an arc-shaped segment with the opening open downward, so as to improve the stability of the stabilizing cable 32 and the load-bearing performance of the load-bearing cable 33, respectively.

[0067] As shown in Figure 3 , in some embodiments of the present application, the intermediate support 2 comprises an intermediate column 21 and an intermediate support 22, the intermediate column 21 is arranged in the vertical direction, and the intermediate support 22 is arranged at the top of the intermediate column 21, and the intermediate support 22 can be passed through by the cable assembly 3.

[0068] It can be understood that the intermediate column 21 is fixed in the photovoltaic field area, and the intermediate column 21 is a mounting carrier of the intermediate frame, the intermediate frame can be fixed at the top end of the intermediate column 21 to form a structure for the passing of the cable assembly 3 at the top of the intermediate support 2. Wherein, the intermediate column 21 can be configured as a cement column, a metal column, etc., which is not specifically limited here.

[0069] As shown in the further embodiments of the present application, the intermediate support 22 is provided with a first passing part 221 and a second passing part 222. Figure 6

[0070] Wherein, in combination with Figure 6 and Figure 7 , the first passing part 221 is used for the passing of the stabilizing cable 32, and the height of the stabilizing cable 32 gradually increases from the first passing part 221 to the side away from the first passing part 221 along the first direction; the second passing part 222 is arranged above the first passing part 221 and is used for the passing of the bearing cable 33, and the height of the bearing cable 33 gradually decreases from the second passing part 222 to the side away from the second passing part 222 along the first direction.

[0071] It should be noted that the first passing part 221 can support the stabilizing cable 32 when the stabilizing cable 32 passes through, and the support point position of the intermediate support 22 to the stabilizing cable 32 is the lowest point of the two end stabilizing segments 321 in the two adjacent cable support units 301. Wherein, the first passing part 221 is formed with an arc-shaped plate, the arc-shaped plate is a support point structure of the stabilizing cable 32 at the intermediate support 22, the stabilizing cable 32 can pass from below the arc-shaped plate to press and support the stabilizing cable 32 downward, so that each stabilizing segment 321 of the stabilizing cable 32 is configured as an arc-shaped segment with the opening downward. Preferably, the opening direction of the arc-shaped plate is upward arranged to improve the pressing and supporting effect of the arc-shaped plate on the stabilizing cable 32, to prevent scratching or damaging the stabilizing cable 32.

[0072] It can be further understood that the second passing part 222 is similar in structure to the first passing part 221, the second passing part 222 can support the bearing cable 33 when the bearing cable 33 passes through, and the support point position of the intermediate support 22 to the bearing cable 33 is the highest point of the two end bearing segments 331 in the two adjacent cable support units 301. Wherein, the second passing part 222 is also formed with an arc-shaped plate, the arc-shaped plate is a support point structure of the bearing cable 33 at the intermediate support 22, the bearing cable 33 can pass from above the arc-shaped plate to support the bearing cable 33 upward, so that each bearing segment 331 of the bearing cable 33 is configured as an arc-shaped segment with the opening upward. Preferably, the opening direction of the arc-shaped plate is downward arranged to improve the pressing and supporting effect of the arc-shaped plate on the stabilizing cable 32, to prevent scratching or damaging the bearing cable 33.

[0073] Wherein, referring to Figure 7 ​The first passing portion 221 and the second passing portion 222 can support the stabilizing cable 32 and the bearing cable 33 by arranging the arc-shaped plates, and when the tension and cable force of the cable assembly 3 are adjusted by the end portion support 1, the stabilizing cable 32 and the bearing cable 33 can be supported by the arc-shaped plates, so as to adjust the directions of the stabilizing cable 32 and the bearing cable 33.

[0074] Specifically, the first passing portion 221 is provided with a first arc-shaped plate, the opening of the first arc-shaped plate is open upward (i.e. toward the side of the second passing portion 222), and the stabilizing cable 32 is supported on the side surface of the first arc-shaped plate away from the opening, so as to play an arc-shaped supporting role on the stabilizing cable 32 and guide the direction of the stabilizing cable 32; the second passing portion 222 is provided with a second arc-shaped plate, the opening of the second arc-shaped plate is open downward (i.e. toward the side of the first arc-shaped plate), and the bearing cable 33 is supported on the side surface of the second arc-shaped plate away from the opening, so as to play an arc-shaped supporting role on the bearing cable 33 and guide the direction of the bearing cable 33.

[0075] The arc-shaped plate (i.e. the first arc-shaped plate and the second arc-shaped plate) can be connected and matched with the middle support 22 by a connecting structure, so as to define a structure for the stabilizing cable 32 and the bearing cable 33 to pass through by matching the arc-shaped plate with the middle support 22.

[0076] As shown in FIG. 1, Figure 3 In some embodiments of the present application, the cable assembly 3 is multiple groups, and the multiple groups of cable assemblies 3 are arranged along the second direction and connected between the two end portion supports 1, and a plurality of middle supports 2 are arranged between the two end portion supports 1, each group of middle supports 2 includes at least one middle support 2, and each group of middle supports 2 is connected and matched with a group of cable assemblies 3, so as to support a group of cable assemblies 3 by a group of middle supports 2. The first direction and the second direction are arranged vertically.

[0077] Therefore, a group of installation supports can be used to install and fix a plurality of groups of cable assemblies 3, so as to connect the cable assemblies 3 between the two end portion supports 1, and the load bearing capacity of the photovoltaic support system 100 can be improved.

[0078] As shown in FIG. 1, Figure 3 In a specific embodiment of the present application, two groups of cable assemblies 3 are connected between the two end portion supports 1, and correspondingly, two groups of middle supports 2 arranged along the second direction are arranged between the two end portion supports 1, and each group of middle supports 2 is arranged correspondingly with a group of cable assemblies 3, so as to support a group of cable assemblies 3 by a group of middle supports 2.

[0079] It should be noted that the two end supports 1 can also be connected with three groups of cable assembly 3, four groups of cable assembly 3, and correspondingly, a plurality of intermediate supports 2 are arranged between the two end supports 1 to match the plurality of cable assembly 3. The number of cable assembly 3 installed on the mounting bracket and the number of intermediate supports 2 arranged between the two end supports 1 are not specifically limited here.

[0080] As shown in the further embodiments of the present application, Figure 3 the photovoltaic support system 100 includes a plurality of mounting brackets, and the plurality of mounting brackets are arranged in the second direction to increase the number of mounting brackets and the number of intermediate supports 2 and cable assembly 3 matched with the mounting brackets, so as to further improve the carrying capacity of the photovoltaic support system 100. Each group of mounting brackets includes two end supports 1 arranged in the first direction.

[0081] It should be noted that the number of mounting brackets arranged in the photovoltaic support system 100 can be designed according to the size requirements of the photovoltaic field area, so as to increase the size of the photovoltaic support system 100 in the second direction by arranging a plurality of mounting brackets and a plurality of intermediate supports 2 and a plurality of cable assembly 3 matched with the plurality of mounting brackets, and improve the carrying capacity of the photovoltaic support system 100. A larger number of photovoltaic modules 200 can be laid in the photovoltaic support system 100.

[0082] Among them, in the photovoltaic field area, the first direction is preferably east-west direction, and the second direction is preferably north-south direction, so as to facilitate arranging the photovoltaic modules 200 at a position suitable for illumination. Of course, the first direction and the second direction are not limited to this, and can be adjusted accordingly according to the site conditions of the photovoltaic field area.

[0083] As shown in some embodiments of the present application, Figure 3 the photovoltaic support system 100 further includes a connection structure 4, and the connection structure 4 is used to connect the plurality of cable assembly 3 arranged in the second direction, so as to improve the structural strength, stability and carrying capacity at the cable assembly 3.

[0084] It can be understood that the plurality of cable assembly 3 can be connected transversely (i.e. connected in the second direction) through the connection structure 4, so as to form a stable array of the plurality of cable assembly 3, so as to jointly bear the photovoltaic array composed of the photovoltaic modules 200 through the plurality of cable assembly 3.

[0085] As shown in further embodiments of the present application, Figure 3 the connection structure 4 is arranged in the first direction to further improve the connection stability and reliability between the plurality of cable assembly 3 by arranging a plurality of connection structures 4.

[0086] Referring to Figure 3In one group of cable support units 301, two groups of connecting structures 4 can be connected, and the two groups of connecting structures 4 can be arranged at positions close to the three-equal points of the cable support units 301 in the first direction, so as to improve the stability between the multiple groups of cable assemblies 3 by arranging multiple groups of connecting structures 4.

[0087] With reference to Figure 6 The connecting structure 4 has multiple connecting sections between the two groups of cable support units 301 arranged in the second direction, so as to connect the two groups of cable support units 301 through the multiple connecting sections, such as connecting the stabilizing sections 321 in one group of cable support units 301 and the bearing sections 331 in the other group of cable support units 301 through the connecting sections, i.e., connecting the two groups of cable support units 301 in the shape of "8" crossing each other. Meanwhile, the stabilizing sections 321 and the bearing sections 331 in the same group of cable support units 301 can also be connected through the connecting sections.

[0088] In further embodiments of the present application, the photovoltaic support system 100 further comprises limiters 5 and wind-resistant cables 6. The limiters 5 are arranged in the photovoltaic field, and the limiters 5 are fixed relative to the intermediate support 2. The wind-resistant cables 6 are connected between the connecting structures 4 and the limiters 5, so as to connect the connecting structures 4 and the limiters 5 through the wind-resistant cables 6, thereby improving the wind-resistant performance of the multiple groups of cable assemblies 3.

[0089] The limiters 5 can be limited displacement of the cable support units 301 when subjected to wind load within the allowable stroke of the limiters 5. It can be understood that when the photovoltaic support system 100 is in an environment with wind, the force of the wind can be fed back to the cable assemblies 3. Through the cooperation of the wind-resistant cables 6 and the connecting structures 4, the displacement of the multiple groups of cable assemblies 3 under the action of the wind can be limited, so as to prevent the position of the multiple groups of cable assemblies 3 from being greatly deviated or twisted and deformed, thereby improving the wind-resistant performance of the photovoltaic support system 100.

[0090] With reference to Figure 3 In some embodiments of the present application, the limiters 5 and the wind-resistant cables 6 are arranged on both sides of the multiple groups of cable assemblies 3 in the second direction, so as to form a wind-resistant limiting structure on the periphery of the arrangement area of the cable assemblies 3, thereby improving the wind-resistant performance of the photovoltaic support system 100.

[0091] It should be noted that "on both sides of the multiple groups of cable assemblies 3 in the second direction" means that, in the projection in the vertical direction, the limiters 5 are arranged in the outer side area of the projection of the multiple groups of cable assemblies 3 in the second direction.

[0092] In some embodiments of the present application, each limiter 5 is connected with at least one wind-resistant cable 6.

[0103] (2) In the cable support unit 301, the stabilizing section 321 and the bearing section 331 are both arranged in an arch shape, which can improve the stability and bearing capacity of the cable assembly 3. At the same time, the installation section 311, the bearing section 331 and the stabilizing section 321 in the cable support unit 301 are arranged in the same plane, the function of each cable structure is clear, and it is convenient to cooperate with the connection structure 4 to control the up-down displacement of the cable support unit 301 under the action of the wind.

[0104] Among them, two or more cable support units 301 can be used to bear the photovoltaic module 200, so that the photovoltaic module 200 can be arranged at the best inclination angle, and the photovoltaic module 200 can also be installed in any inclination angle form.
