[0046] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.
[0047] Reference below Figure 1-Figure 9 A flexible photovoltaic bracket and a photovoltaic system according to embodiments of the present application are described.
[0048] The present application embodiment provides a flexible photovoltaic bracket, such as Figure 1-Figure 3 As shown, the flexible photovoltaic support includes a support assembly, a rope 500 , a flexible cable 200 and at least one prefabricated first base member 300 .
[0049] Among them, Figure 1-Figure 3 As shown, the support assembly can be used to support the end, middle, or other positions of the rope 500.
[0050] like Figure 1-Figure 3As shown, the rope 500 is installed on the supporting assembly for installing the photovoltaic assembly. The rope 500 may be a steel wire rope, a steel cable, a steel strand or other structures. For example, the rope 500 is a steel strand.
[0051] like Figure 1-Figure 3 As shown, a plurality of support components may be distributed and spaced apart along a horizontal lateral direction, and the rope 500 may be extended and arranged along the horizontal lateral direction; the main portion of each support component may extend along a horizontal longitudinal direction, and a plurality of ropes 500 may be distributed and spaced apart along the horizontal longitudinal direction in the support component.
[0052] like Figure 1-Figure 3 As shown, the rope 500 is provided in plurality, the plurality of ropes 500 are arranged at intervals along the extension direction of the support assembly, and each rope 500 is installed on the support assembly.
[0053] like Figure 4 Figure 7 As shown, when there are at least two prefabricated first basic members 300, two adjacent first basic members 300 are spliced together, and the two first basic members 300 can be spliced together by bolts, wedge-shaped structures, mortise and tenon structures, or by setting embedded parts.
[0054] like Figure 4 Figure 7 As shown, the first base member 300 may be a rectangular structure, a circular structure, a trapezoidal structure or other shaped structures. For example, the first base member 300 is a rectangular structure.
[0055] like Figure 1-Figure 3 As shown, two ends of the flexible cable 200 are respectively connected to the support assembly and the first base member 300 , and the flexible cable 200 may be a steel wire rope, a steel cable or other structures.
[0056] During the actual implementation process, the required number of first base components 300 are prefabricated in the factory according to the needs of the actual construction site, and the prefabricated first base components 300 are transported to the construction site by transportation equipment, and multiple first base components 300 are spliced at designated positions, and multiple first base components 300 are connected to the lower end of the flexible cable 200.
[0057] The base member used to connect with the flexible cable 200 is arranged to be composed of a plurality of first base members 300, that is, the volume of the first base member 300 is relatively small relative to the overall volume of the base members required for the flexible cable 200. Therefore, in the process of transporting the first base member 300, a slightly smaller transportation equipment can be used, and there is no need to use large equipment to enter the construction site for casting, so that the flexible photovoltaic bracket can be suitable for scenes with smaller spaces. Since the processing conditions in the factory are better than those at the construction site, the first base member 300 is prefabricated in the factory to ensure the processing quality of the first base member 300, reduce the processing cost of the first base member 300, shorten the construction and maintenance period, and at the same time, the construction work is less affected by seasonal climate, which can reduce the work intensity of construction personnel. In addition, the appropriate number of first base members 300 can be selected according to the actual load size of the support assembly to avoid waste caused by excess first base members 300, which can further reduce costs.
[0058] According to the flexible photovoltaic bracket provided in the embodiment of the present application, by splicing multiple prefabricated first basic components 300 and connecting them with flexible cables 200, there is no need to use large equipment, so that the flexible photovoltaic bracket can be suitable for scenes with smaller spaces. The first basic components 300 are prefabricated in the factory, which can ensure the processing quality of the first basic components 300, reduce processing costs, shorten construction and maintenance periods, and at the same time, the construction work is less affected by seasonal climate, which can reduce the work intensity of construction personnel.
[0059] In some embodiments, Figure 4-Figure 9 As shown, the flexible photovoltaic support also includes at least one prefabricated second base member 400, and the lower end of the support assembly is supported on the second base member 400. When there are at least two second base members 400, two adjacent second base members 400 are spliced.
[0060] Among them, Figure 8 As shown, when there are at least two prefabricated second basic members 400, two adjacent second basic members 400 are spliced together, and the two second basic members 400 can be spliced together by bolts, wedge-shaped structures, mortise and tenon structures, or by setting embedded parts.
[0061] The structure of the second base member 400 may be the same as that of the first base member 300, or the structure of the second base member 400 may be different from that of the first base member 300, for example. Figure 4-Figure 9 As shown, the structure of the second base member 400 is the same as that of the first base member 300 .
[0062] like Figure 4-Figure 9 As shown, the second base member 400 may be a rectangular structure, a circular structure, a trapezoidal structure or other shaped structures. For example, the second base member 400 is a rectangular structure.
[0063] During the actual implementation process, the required number of second foundation members 400 are prefabricated in the factory according to the needs of the actual construction site, and the prefabricated second foundation members 400 are transported to the construction site by transportation equipment, multiple second foundation members 400 are spliced at designated positions, and the support assembly is installed on the second foundation member 400. The support assembly can be supported on the second foundation member 400 and connected to the second foundation member 400.
[0064] The base member for supporting the supporting assembly is configured to be composed of a plurality of second base members 400, that is, the volume of the second base member 400 is smaller than the overall volume of the base member required for the flexible cable 200. Therefore, a slightly smaller transportation equipment can be used in the process of transporting the second base member 400, and there is no need to use large equipment to enter the construction site for casting, so that the flexible photovoltaic bracket can be suitable for scenes with smaller spaces. Since the processing conditions in the factory are better than those at the construction site, the second base member 400 is prefabricated in the factory to ensure the processing quality of the second base member 400, reduce the processing cost of the second base member 400, shorten the construction and maintenance period, and at the same time, the construction work is less affected by seasonal climate, which can reduce the work intensity of construction personnel. In addition, the appropriate number of second base members 400 can be selected according to the actual load size of the supporting assembly to avoid waste caused by excess second base members 400, which can further reduce costs.
[0065] In addition, by setting the structure of the second base member 400 to be the same as that of the first base member 300, the types of parts can be reduced, that is, the support assembly and the flexible cable 200 can both be supported and connected using the same type of base member, thereby reducing processing and transportation costs and reducing production difficulty.
[0066] In some embodiments, Figure 1 As shown, the flexible cable 200 includes a diagonal cable 210 and a windproof cable 220, and the supporting assembly includes a side column 120, a center column 130, a windproof structure 160 and at least two end beams 110, the side columns 120 and the center column 130 are respectively connected to the at least two end beams 110, the windproof structure 160 is connected to the rope 500, and the windproof structure 160 is installed between the side column 120 and the center column 130, the two ends of the windproof cable 220 are respectively connected to the windproof structure 160 and the corresponding first foundation member 300, and the two ends of the diagonal cable 210 are respectively connected to the end beam 110 and the corresponding first foundation member 300.
[0067] Among them, Figure 1 As shown, the support assembly may include three end beams 110 , two windproof structures 160 , a plurality of side columns 120 , a plurality of center columns 130 , and the flexible cable 200 may include a plurality of inclined cables 210 and a plurality of windproof cables 220 .
[0068] like Figure 1 As shown, two of the three end beams 110 are used to be connected to the side columns 120, and the two end beams 110 are both connected to a plurality of side columns 120, and the plurality of side columns 120 are spaced apart along the axial direction of the end beams 110, and the inclined cable 210 is located at both ends of the end beams 110 and between two adjacent side columns 120, and both ends of the inclined cable 210 are respectively connected to the corresponding end beams 110 and the corresponding first base member 300, and the two end beams 110 connected to the side columns 120 are respectively connected to the two ends of the rope 500.
[0069] like Figure 1 As shown, the remaining one of the three end beams 110 is used to connect to the center column 130, which is located between the end beams 110 at both ends and connected to the middle of the rope 500, and multiple center columns 130 are spaced apart along the axial direction of the end beam 110.
[0070] like Figure 1 As shown, the two windproof structures 160 are respectively located between the central column 130 and the side columns 120 at both ends. The windproof structures 160 are also connected to the rope 500. Both sides of the windproof structure 160 along the axial direction of the end beam 110 are connected to one end of the windproof cable 220, and the other end of the windproof cable 220 is connected to the corresponding first base member 300.
[0071] Since the windproof structure 160 is located near the middle of the flexible photovoltaic support, the load borne by the windproof cable 220 and the windproof structure 160 is relatively small, so the windproof cable 220 can be connected to a first base component 300 to reduce the number of first base components 300 and reduce production costs; since the inclined cable 210 is located on the outside of the flexible photovoltaic support, the load borne by the inclined cable 210 is relatively large, so the inclined cable 210 can be connected to multiple spliced first base components 300 to improve the stability of the inclined cable 210.
[0072] By connecting the inclined cable 210 and the windproof cable 220 to the corresponding first base component 300 respectively, the types of parts can be reduced. Only the first base component 300 can be used to achieve connection with the inclined cable 210 and the windproof cable 220, thereby reducing processing and transportation costs and reducing production difficulty.
[0073] It should be noted that other appropriate numbers may be selected for the above structures.
[0074] By providing the windproof structure 160 in the supporting assembly, the windproof performance of the flexible photovoltaic support can be improved and the stability of the rope 500 can be improved.
[0075] In some embodiments, Figure 1-Figure 3As shown, at least one of the center column 130 , the side columns 120 , the herringbone columns 140 and the inner supports 150 is supported on the site by the second foundation member 400 .
[0076] The supporting assembly includes an end beam 110 , a center column 130 , a side column 120 , a herringbone column 140 and an inner support 150 , all of which are used to support the end beam 110 .
[0077] The flexible photovoltaic support can be in at least one of the following structural forms:
[0078] First, if Figure 1 As shown, the support assembly includes an end beam 110 , a side column 120 , a windproof structure 160 and a center column 130 , and the flexible cable 200 includes a stay cable 210 and a windproof cable 220 .
[0079] The side columns 120 and the center column 130 are respectively connected to different end beams 110. The side columns 120, the windproof structure 160, the center column 130, the windproof structure 160 and the side columns 120 are sequentially arranged at intervals along the extension direction of the rope 500. The inclined cable 210 is connected to the end beam 110 used to be connected to the side column 120. The windproof cable 220 is connected to the windproof structure 160 along the axial direction of the end beam 110. The side columns 120 and the center column 130 are both vertically arranged.
[0080] Both the side columns 120 and the center column 130 are supported on the site by the second base member 400. Since the center column 130 is located in the middle of the flexible photovoltaic support, the load it bears is relatively small, so the center column 130 can be supported by a second base member 400. The side columns 120 bear a relatively large load, so the center column 130 can be supported by multiple spliced second base members 400.
[0081] The inclined cable 210 and the windproof cable 220 are both connected to the corresponding first base member 300 . The windproof cable 220 can be connected to one first base member 300 , and the inclined cable 210 can be connected to a plurality of spliced first base members 300 .
[0082] By providing a flexible photovoltaic bracket with the above-mentioned structural form, the wind resistance of the flexible photovoltaic bracket can be improved and the stability of the flexible photovoltaic bracket can be ensured.
[0083] Second, if Figure 2 As shown, the support assembly includes an end beam 110 , a side column 120 , an inner support 150 and a center column 130 .
[0084] The side columns 120 and the center column 130 are respectively connected to different end beams 110. The side columns 120, the center column 130 and the side columns 120 are spaced apart along the extension direction of the rope 500. The inner support 150 is connected to the end beam 110 used to support the top of the side column 120, and the inner support 150 is located on the side of the side column 120 close to the center column 130. The side columns 120, the inner support 150 and the center column 130 are all supported on the site through the second foundation member 400.
[0085] By providing a flexible photovoltaic bracket with the above-mentioned structural form, the supporting force of the flexible photovoltaic bracket can be improved and the stability of the flexible photovoltaic bracket can be ensured.
[0086] Third, if Figure 3 As shown, the support assembly includes an end beam 110 , a herringbone column 140 and a center column 130 .
[0087] The herringbone gate post and the center column 130 are respectively connected to different end beams 110 , and the herringbone columns 140 , the center column 130 and the herringbone columns 140 are spaced apart along the extension direction of the rope 500 . The herringbone columns 140 and the center column 130 are all supported on the site by the second foundation member 400 .
[0088] By providing a flexible photovoltaic bracket with the above-mentioned structural form, the tensile strength and compressive strength of the flexible photovoltaic bracket can be improved, thereby ensuring the stability of the flexible photovoltaic bracket.
[0089] In some embodiments, Figure 4-Figure 6 As shown, the plurality of first base members 300 are distributed in a horizontal direction.
[0090] Among them, Figure 4-Figure 6 As shown, a plurality of first base members 300 are arranged horizontally in a flat pattern. The plurality of first base members 300 can be arranged in a rectangular structure, a trapezoidal structure or other shapes, for example, Figure 4 As shown, the four first basic members 300 are laid out horizontally to form a rectangular structure, and the four first basic members 300 are respectively located at the four corners of the rectangular structure, and the flexible cable 200 is connected to the center of the four first basic members 300 .
[0091] By distributing the multiple first base members 300 in the horizontal direction, the overall cross-sectional area of the multiple first base members 300 after being spliced can be made larger, thereby improving the tensile strength of the multiple first base members 300 after being spliced, and improving the structural strength and stability of the multiple first base members 300 after being spliced.
[0092] In some embodiments, Figure 4 As shown, there are multiple flexible cables 200 , and multiple first base members 300 form multiple groups of first base members 300 . The multiple flexible cables 200 are connected to the multiple groups of first base members 300 in a one-to-one correspondence.
[0093] When the flexible cable 200 is a stay cable 210, a plurality of stay cables 210 may be spaced apart along the axial direction of the end beam 110, and each stay cable 210 is respectively connected to a group of first base members 300, and each group of first base members 300 may include a plurality of first base members 300 spliced to each other, for example, Figure 4 As shown, each group of first base members 300 may include four first base members 300, the four first base members 300 are distributed in the horizontal direction, a plurality of inclined cables 210 are connected to the plurality of groups of first base members 300 in a one-to-one correspondence, and two adjacent groups of first base members 300 are spaced apart.
[0094] By providing a plurality of inclined cables 210 connected to a plurality of groups of first base members 300 in a one-to-one correspondence, the stability of each inclined cable 210 can be ensured, thereby improving the overall stability of the flexible photovoltaic support.
[0095] In some embodiments, Figure 5 As shown, a plurality of groups of first basic components 300 are spliced and connected into one body.
[0096] Among them, Figure 5 As shown, there is a gap between two adjacent groups of first base members 300, and the gap can be filled with the remaining first base members 300, that is, the two adjacent groups of first base members 300 are spliced and connected into one body through the remaining first base members 300. At this time, multiple groups of first base members 300 are spliced and connected into a whole, and multiple inclined cables 210 are all connected to the spliced integral first base member 300.
[0097] By splicing multiple groups of first basic components 300 into a whole, the cross-sectional area can be increased, thereby improving the tensile strength of the multiple first basic components 300 after splicing, and improving the overall stability of the flexible photovoltaic support.
[0098] In some embodiments, Figure 6 As shown, a plurality of first base members 300 and at least one second base member 400 are spliced and connected together in a horizontal direction.
[0099] Among them, Figure 6 As shown, when the flexible photovoltaic support includes multiple side columns 120 and multiple inclined cables 210, each side column 120 is supported on a second base member 400, each inclined cable 210 is connected to a group of second base members 400 distributed in the horizontal direction, and each second base member 400 can be spliced and connected to multiple groups of first base members 300 through the remaining first base members 300 or the remaining second base members 400, that is, the multiple side columns 120 and the multiple inclined cables 210 are all installed on the spliced integral base member.
[0100] By splicing a plurality of first base members 300 and at least one second base member 400 together in a horizontal direction, the cross-sectional area of the spliced base members can be further increased, thereby improving the structural strength and stability of the flexible photovoltaic support.
[0101] In some embodiments, Figure 7 As shown, there are multiple first base members 300 , and the multiple first base members 300 are stacked up and down.
[0102] Among them, Figure 7 As shown, a plurality of first base members 300 are stacked up and down in the vertical direction. For example, two first base members 300 are stacked up and down in the vertical direction, and the flexible cable 200 is connected to the first base member 300 located at the top.
[0103] like Figure 7 As shown, when the flexible photovoltaic support includes multiple inclined cables 210, the multiple first base members 300 are divided into multiple groups of first base members 300, each inclined cable 210 can be respectively connected to a group of first base members 300, each group of first base members 300 is composed of multiple first base members 300 stacked up and down, and the multiple groups of first base members 300 are spaced apart along the axial direction of the end beam 110.
[0104] By stacking multiple first base members 300 up and down, the overall vertical support capacity of the multiple first base members 300 after being spliced can be improved, that is, the overall compressive resistance of the multiple first base members 300 after being spliced can be improved, thereby ensuring the overall stability of the flexible photovoltaic bracket.
[0105] In some embodiments, Figure 8 As shown, there are multiple second base members 400 , and the multiple second base members 400 are distributed along the horizontal direction.
[0106] Among them, Figure 8 As shown, multiple second base members 400 are laid out in a horizontal direction. The multiple second base members 400 can be laid out into a rectangular structure, a trapezoidal structure or other shape structures. For example, four second base members 400 are laid out in a horizontal direction into a rectangular structure, and the four second base members 400 are respectively located at the four corners of the rectangular structure, and the supporting assembly is supported on the center of the four second base members 400.
[0107] By distributing the multiple second base members 400 in the horizontal direction, the overall cross-sectional area of the multiple second base members 400 after being spliced can be larger, thereby improving the tensile strength of the multiple second base members 400 after being spliced, and improving the structural strength and stability of the multiple second base members 400 after being spliced.
[0108] In some embodiments, Figure 8As shown, there are multiple second base members 400 , and the multiple second base members 400 are stacked up and down.
[0109] Among them, Figure 8 As shown, a plurality of second base members 400 are stacked up and down in the vertical direction. For example, two second base members 400 are stacked up and down in the vertical direction, and the supporting assembly is supported on the second base member 400 located at the top.
[0110] When the flexible photovoltaic support includes multiple side columns 120 or multiple center columns 130 or multiple herringbone columns 140, the multiple second base members 400 are divided into multiple groups of second base members 400. For example, the flexible photovoltaic support is buckled with multiple herringbone columns 140, and each herringbone column 140 can be respectively connected to a group of second base members 400, and each group of second base members 400 is composed of multiple second base members 400 stacked up and down, and the multiple groups of second base members 400 are spaced apart along the axial direction of the end beam 110.
[0111] By stacking multiple second base members 400 up and down, the overall vertical supporting capacity of the multiple second base members 400 after being spliced can be improved, that is, the overall compressive resistance of the multiple second base members 400 after being spliced can be improved, thereby ensuring the overall stability of the flexible photovoltaic bracket.
[0112] In some embodiments, Figure 8 and Fig. 9 As shown, the support assembly includes an end beam 110 , a first column 141 and a second column 142 .
[0113] Among them, Figure 8 and Fig. 9 As shown, when the support assembly includes the herringbone column 140 , the herringbone column 140 may include a first column 141 and a second column 142 , and the end beam 110 is connected to the rope 500 .
[0114] like Figure 8 and Fig. 9 As shown, the upper end of the first column 141 is connected to the end beam 110, and the lower end of the first column 141 is located on the side of the end beam 110 close to the rope 500, the upper end of the second column 142 is connected to the end beam 110, and the lower end of the second column 142 is located on the side of the end beam 110 away from the rope 500, that is, the first column 141 and the second column 142 form a herringbone structure, and the first column 141 and the second column 142 are respectively located on both sides of the end beam 110.
[0115] like Figure 8 As shown, the lower end of the first column 141 is supported on at least two second base members 400 stacked up and down, and the lower end of the second column 142 is supported on at least two second base members 400 distributed in the horizontal direction.
[0116] Since the rope 500 has a certain pulling force on the end beam 110, and the end beam 110 itself has gravity, the second column 142 located on the side of the end beam 110 away from the rope 500 is subjected to a larger pulling force, and the first column 141 located on the side of the end beam 110 close to the rope 500 is subjected to a larger pressure. The multiple second base members 400 distributed in the horizontal direction have a strong tensile resistance and can provide a larger tensile resistance for the second column 142. The multiple second base members 400 stacked up and down in the vertical direction have a strong compressive resistance and can provide a larger compressive resistance for the first column 141, thereby extending the service life of the first column 141 and the second column 142.
[0117] In some embodiments, Fig. 9 As shown, the flexible photovoltaic support further includes a prefabricated support rod 600 , the upper end of the support rod 600 is connected to the lower end of the second base member 400 .
[0118] Among them, Fig. 9 As shown, the support assembly can be supported on a second base member 400, and the upper end of the support rod 600 is connected to the lower end of the second base member 400. For example, the first column 141 and the second column 142 in the herringbone column 140 can also be supported on a second base member 400 respectively, and the lower end of each second base member 400 is connected to a support rod 600.
[0119] The support rod 600 may be a prefabricated pile, an anchor rod, a prestressed pipe pile, a steel pile, a screw pile or other structures.
[0120] By providing a prefabricated support rod 600, the support rod 600 can be used in conjunction with the second base member 400 to form a composite foundation to improve the horizontal force resistance of the support rod 600 and the pull-out and compression resistance of the second base member 400, thereby further ensuring the stability of the flexible photovoltaic bracket.
