[0040] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary only for explaining the present application and should not be construed as limiting the present application.

[0041] The present application discloses a photovoltaic support 100.

[0042] Below, reference is made to Figures 1-6 Describe the photovoltaic support 100 according to the embodiment of the present application.

[0043] In some embodiments, as Figures 1-5 shown, the photovoltaic support 100 includes: a main support structure, a second support member 120, and a suspension structure 130.

[0044] The main support structure includes at least two first support members 111 spaced apart in a first direction and a component cable 112 connected between the first support members 111. The component cable 112 has a first assembly structure for installing photovoltaic modules; the second support member 120 is arranged outside the at least two first support members 111, and the second support member 120 and the first support member 111 are spaced apart in the first direction; the suspension structure 130 is connected to the first support member 111 and the second support member 120, and the suspension structure 130 has a second assembly structure for installing photovoltaic modules; wherein, the minimum distance Lmin between the second support member 120 and the main support structure and the span S of the main support structure satisfy: 1 / 5 ≤ Lmin / S ≤ 1 / 3.

[0045] Specifically, Lmin / S can be 1 / 5, 3 / 13, 2 / 7, 1 / 3, or other values between 1 / 5 and 1 / 3, without limitation here.

[0046] As Figures 1-5 shown, the main support structure can be a common large-span flexible photovoltaic support. Specifically, the main support structure can include two rows of first support members 111 supported at both ends and a component cable 112 connected to the two rows of first support members 111. Each row of first support members 111 can include a plurality of first support members 111 arranged separately along the second direction. The photovoltaic modules can be laid on the component cable 112 through the first assembly structure.

[0047] Among them, the first support member 111 can adopt a rigid frame structure or a column structure. The rigid frame structure can include, but is not limited to, a herringbone rigid frame, a bent frame, an internally braced rigid frame, or an externally stayed rigid frame, without limitation here.

[0048] For example, in some embodiments, as Figures 1-5 shown, the first support member 111 adopts a herringbone rigid frame.

[0049] The component cable 112 can adopt any one or a combination of multiple of steel strands, steel ropes, steel cables, steel wires, or steel chains.

[0050] For example, in some embodiments, the component cable 112 adopts a steel wire.

[0051] The second support member 120 can be connected in series with the first support member 111 through a suspension structure 130 to share the horizontal force caused by the ultra-large span of the main support structure. The photovoltaic modules can be laid on the suspension structure 130 through the second assembly structure.

[0052] Among them, the second support member 120 can adopt a rigid frame structure or a column structure. The rigid frame structure can include, but is not limited to, a herringbone rigid frame, a bent frame, an internally braced rigid frame, or an externally stayed rigid frame, without limitation here.

[0053] For example, in some embodiments, as Figures 1-3 shown, the first support member 111 adopts a herringbone rigid frame.

[0054] For example, in some other embodiments, as Figures 4-5 shown, the second support member 120 at one end of the main support structure adopts a herringbone rigid frame, and the second support member 120 at the other end of the main support structure adopts a bent frame.

[0055] For example, in some other embodiments, the first support member 111 adopts a column structure.

[0056] The suspension structure 130 can adopt any one or a combination of a cable structure, a truss structure, or a beam structure. The cable structure can include, but is not limited to, any one or a combination of steel strands, steel ropes, steel cables, steel wires, or steel chains, and there is no limitation here.

[0057] For example, in some embodiments, as Figures 1-3 shown, the suspension structure 130 adopts a cable structure.

[0058] For example, in some other embodiments, as Figures 4-5 shown, the suspension structure 130 on one side of the main support structure adopts a cable structure, and the suspension structure 130 on the other side of the main support structure adopts a beam structure.

[0059] For example, in some other embodiments, the suspension structure 130 adopts a truss structure.

[0060] It can be understood that due to the excessive span of the main support structure, that is, the distance S between the first support members at both ends is too large. In order to bear the horizontal force caused by the super-large-span structure to reduce the risk of mid-span collapse, the size of the first support member is often too large, consuming a large amount of materials, and the number of pile foundations at the anchoring position of the first support member is too large and the size is also large. A large number of pile foundations need to be borne within a small area of land, which significantly increases the extrusion stress of the soil around the pile foundations, causing the surface soil to bulge vertically and the deep soil to move horizontally outward along the pile circumference. The occurrence of the above soil squeezing effect will increase the pile top elevation error during construction and affect the bearing capacity of the pile foundation.

[0061] In actual implementation, as Figures 1-5 shown, second support members 120 are provided at both ends of the main support structure, and the second support members 120 and the first support members 111 are arranged separately along the first direction. The first direction can be the length direction of the component cable 112. The distance between the first support members 111 and the second support members 120 is much smaller than the span of the main support structure. Under the series action of the suspension structure 130, the second support members 120 can assist the first support members 111 to share the horizontal force caused by the super-large-span structure in the middle. Moreover, many pile foundations originally concentrated in the soil where the first support members 111 are located can be dispersed to the soil where the first support body is located and the soil where the second support body is located under the action of the horizontal force sharing. In this way, the distance between each pile foundation is effectively increased.

[0062] It should be noted that in this embodiment, as Figures 1-3 shown, both ends of the component cable 112 can extend along the first direction to the second support members 120 at both ends and be anchored to the second support members 120 at both ends. At this time, the suspension structure 130 can be tensioned below the component cable 112.

[0063] Alternatively, in some other embodiments, as Figures 4-5 shown, one end of the component cable 112 can extend in the first direction to the second support member 120 at this end and be anchored to the second support member 120 at this end, and the other end of the component cable 112 is not extended.

[0064] Alternatively, in still some other embodiments, neither end of the component cable 112 is extended.

[0065] The photovoltaic support 100 provided by the embodiments of the present application, through the settings of the above-mentioned second support member 120 and the suspension structure 130, in cooperation with the range limitation of Lmin / S, effectively shares the horizontal force caused by the super-large-span flexible support structure in the middle, reduces the force on the first support member 111, thereby reducing the component size of the first support member 111, and further facilitating the fabrication, transportation and construction of the first support member 111 and its joints. Without increasing the size and quantity of the pile foundations and the overall cost, the numerous pile foundations originally concentrated within the large-span range are dispersed to the large-span and small-span ranges, significantly alleviating the soil squeezing effect between piles, reducing the pile top elevation error caused by the soil squeezing effect during the later pile foundation construction, and at the same time improving the bearing capacity of the pile foundations, thereby enhancing the stability of the entire photovoltaic support 100.

[0066] In some embodiments, as Figures 4-5 shown, the second support member 120 can include multiple groups distributed in the first direction, and each group can include multiple second support members 120 distributed in the second direction. A suspension structure 130 is connected between adjacent two groups of second support members 120, and between the first support member 111 and the innermost group of second support members 120.

[0067] Herein, multiple groups means two or more groups, and multiple means two or more. For example, in some embodiments, as Figures 4-5 shown, the second support member 120 can include three groups distributed in the first direction, and each group can include three second support members 120 distributed in the second direction.

[0068] In this embodiment, as Figures 4-5As shown, the second support member 120 at the first end of the main support structure adopts a herringbone rigid frame. A plurality of second support members 120 at the first end can be distributed along the second direction to form a group. The suspension structure 130 at the first end can adopt a cable structure. The suspension structure 130 can be connected between a plurality of second support members 120 at the first end and the first support member 111 at the first end. The first end of the component cable 112 can extend along the first direction to the second support member 120 at the first end and be anchored to the second support member 120 at the first end. Multiple groups of second support members 120 at the second end of the main support structure can form a bent structure. The suspension structure 130 at the second end can adopt a beam structure. The suspension structure 130 can be arranged between multiple groups of second support members 120 at the second end, and the suspension structure 130 can also be arranged between the innermost group of second support members 120 and the first support member 111 at the second end. The second end of the component cable 112 does not extend.

[0069] Wherein, the angle between the first direction and the second direction can be an acute angle, a right angle or an obtuse angle, and there is no limitation here.

[0070] For example, in some embodiments, the angle between the first direction and the second direction can be a right angle.

[0071] It should be noted that although the bent structure can increase the dispersion of the pile foundation, considering the cost, in actual design, at most three groups of second support members 120 are arranged along the first direction on one side of the main support structure.

[0072] The photovoltaic support 100 provided by the embodiment of the present application, by designing the second support member 120 as a bent structure, enhances the spanning ability of the photovoltaic support 100, further expands the spacing between each pile foundation, effectively improves the distribution state of the accumulation of many pile foundations in a small area, and reduces the pile top elevation error caused by the pile-soil squeezing effect as much as possible without increasing the overall cost.

[0073] In some embodiments, as Figures 4-5 shown, among multiple groups of second support members 120, the distance Lmax between the outermost group of second support members 120 and the main support structure and the span S of the main support structure can satisfy: 1 / 4 ≤ Lmax / S ≤ 1 / 2.

[0074] Specifically, Lmax / S can be 1 / 4, 1 / 3, 2 / 5, 1 / 2 or other values between 1 / 4 and 1 / 2, and there is no limitation here.

[0075] It can be understood that in the case where only one group of second support members 120 is included on one side, the distance L between the second support member 120 and the main support structure satisfies: 1 / 5 ≤ L / S ≤ 1 / 3.

[0076] When the second support member 120 on one side includes multiple groups arranged at intervals in the first direction, the distance between the innermost group of the second support members 120 and the main support structure, that is, the minimum distance Lmin between the second support member 120 and the main support structure, satisfies: 1 / 5 ≤ Lmin / S ≤ 1 / 3; the distance between the outermost group of the second support members 120 and the main support structure, that is, the maximum distance Lmax between the second support member 120 and the main support structure, satisfies: 1 / 4 ≤ Lmax / S ≤ 1 / 2.

[0077] For the photovoltaic support 100 provided by the embodiment of the present application, through the above range limitation of Lmax / S, it is prevented that Lmax / S is too small to improve the distribution of small - range accumulation of pile foundations, so as to expand the pile distance as much as possible, and then reduce the construction difficulty; and it is prevented that Lmax / S is too large, resulting in an increase in the number and / or size of pile foundations, so as to control the manufacturing cost as much as possible.

[0078] In some embodiments, as Figures 1-3 shown, the photovoltaic support 100 may further include: a stiffening member 140.

[0079] The suspension structure 130 may include a plurality of them arranged separately in the second direction, and the stiffening member 140 may be connected between the plurality of suspension structures 130.

[0080] The stiffening member 140 may adopt a beam structure or a truss structure, which is not limited here. For example, in some embodiments, as Figures 1-3 shown, the stiffening member 140 may adopt a truss structure.

[0081] In this embodiment, as Figures 1-3 shown, the suspension structure 130 may adopt a cable - suspension structure. Specifically, the cable - suspension structure may be arranged as a parallel cable system. In order to increase the structural stiffness and stability at the mid - span position of the cable - suspension structure, a stiffening member 140 may be provided at the mid - span position of the suspension structure 130, that is, the middle position between the first support member 111 and the second support member 120, and the stiffening member 140 may adopt a truss structure.

[0082] For the photovoltaic support 100 provided by the embodiment of the present application, through the above - mentioned setting of the stiffening member 140, the mechanical performance of the suspension structure 130 at the mid - span position can be strengthened, the local stability of the suspension structure 130 can be improved, so that some photovoltaic modules installed on the suspension structure 130 through the second assembly structure can withstand wind loads, snow loads, atmospheric erosion and other external effects, thereby increasing the firmness and reliability of the entire photovoltaic support 100.

[0083] In some embodiments, as Figures 1-3 shown, the photovoltaic support 100 may further include: a first auxiliary cable 150.

[0084] The first auxiliary cable 150 can be connected between the main support structure and the second support member 120.

[0085] The first auxiliary cable 150 can be any one or a combination of multiple types such as steel stranded wire, steel rope, steel cable, steel wire rope or steel chain.

[0086] For example, in some embodiments, the first auxiliary cable 150 is made of steel stranded wire.

[0087] The first auxiliary cable 150 can have various connection form schemes such as X-shaped or fish-belly-shaped, and there is no limitation here.

[0088] For example, in some embodiments, as Figures 1-3 shown, the first auxiliary cable 150 has an X-shaped connection form.

[0089] In the photovoltaic support 100 provided by the embodiments of the present application, through the above setting of the first auxiliary cable 150, as an additional stable structure providing a downward trend force for the overall photovoltaic support 100, the auxiliary suspension structure 130 connects the main support structure and the second support member 120 in series, so that the second support member 120 can better share the horizontal force caused by the ultra-large-span flexible support structure in the middle, thereby facilitating the reduction of the component size of the first support member 111.

[0090] In some embodiments, as Figures 1-2 shown, the first auxiliary cable 150 can be connected between the first support member 111 and the second support member 120.

[0091] In actual implementation, when the span between the first support member 111 and the second support member 120 is relatively large, in other words, as Figures 1-2 shown, when only one group of the second support members 120 on one side is included and the distance L between the second support member 120 and the main support structure is relatively large, it is possible to preferably tension the first auxiliary cable 150 between the first support member 111 and the second support member 120, and both ends of the first auxiliary cable 150 can be respectively anchored to the first support member 111 and the second support member 120 through anchor fittings.

[0092] Or, when multiple groups of the second support members 120 are arranged separately along the first direction on one side ( Figures 4-5 the first auxiliary cable 150 is not shown in both cases), based on the relatively large span of the second support member 120 in the form of a bent frame, at this time, it is possible to preferably tension the first auxiliary cable 150 between the first support member 111 and the outermost group of the second support members 120, and both ends of the first auxiliary cable 150 can be respectively anchored to the first support member 111 and the outermost group of the second support members 120 through anchor fittings.

[0093] In the photovoltaic support 100 provided by the embodiment of the present application, through the structural design of connecting the first auxiliary cable 150 between the first support member 111 and the second support member 120, for the case where the distance between the first support member 111 and the second support member 120 is relatively large, while enhancing the spanning ability of the photovoltaic support 100, the reliability and firmness of the series connection between the main support structure and the second support member 120 are improved, and the structure is simple and convenient for construction.

[0094] In some embodiments, as Figure 3 shown, the first auxiliary cable 150 can be connected between the inter-cable support 115 and the second support member 120.

[0095] In actual implementation, as Figure 3 shown, when only one group of the second support members 120 on one side is included and the distance L between the second support member 120 and the main support structure is relatively small, it is preferable to tension the first auxiliary cable 150 between the inter-cable support 115 and the second support member 120, and both ends of the first auxiliary cable 150 can be respectively anchored to the inter-cable support 115 and the second support member 120 through anchor fittings.

[0096] In the photovoltaic support 100 provided by the embodiment of the present application, through the structural design of connecting the first auxiliary cable 150 between the inter-cable support 115 and the second support member 120, for the case where the distance between the first support member 111 and the second support member 120 is relatively small, the second support member 120 has a good restraint effect on the mid-span collapse of the main support structure, and at the same time, it is beneficial for the concentrated load of the main support structure to be transmitted to the pile foundation through the first support member 111 and the second support member 120, improving the bearing capacity of the entire photovoltaic support 100.

[0097] In some embodiments, as Figures 1-5 shown, the main support structure may further include: a load-bearing cable 113 and a stabilizing cable 114.

[0098] The load-bearing cable 113 can be connected between the first support members 111, and the load-bearing cable 113 can be used for wind pressure resistance; the stabilizing cable 114 can be connected between the first support members 111, and the stabilizing cable 114 can be used for wind uplift resistance.

[0099] The load-bearing cable 113 can be any one or a combination of multiple types among steel strands, steel ropes, steel cables, steel wires or steel chains.

[0100] For example, in some embodiments, the load-bearing cable 113 is a steel wire.

[0101] The stabilizing cable 114 can be any one or a combination of multiple types among steel strands, steel ropes, steel cables, steel wires or steel chains.

[0102] For example, in some embodiments, the stabilizing cable 114 is a steel cable.

[0103] The load-bearing cable 113 and the stabilizing cable 114 can form various connection configurations, including but not limited to an X shape, a triangle, or a fish-belly shape, without limitation here.

[0104] For example, in some embodiments, as Figures 1-5 shown, both ends of the load-bearing cable 113 are respectively anchored to the first support members 111 at both ends of the main support structure, both ends of the stabilizing cable 114 are respectively anchored to the first support members 111 at both ends of the main support structure, and the load-bearing cable 113 and the stabilizing cable 114 are reciprocally and alternately arranged to form an overall fish-belly shape. Among them, the concave curved surface is the load-bearing cable 113, and the convex curved surface is the stabilizing cable 114. Based on the fact that the center of curvature of the load-bearing cable 113 is located above the component cable 112, the load-bearing cable 113 can enhance the ability of the photovoltaic support 100 to resist wind pressure and snow pressure. Based on the fact that the center of curvature of the stabilizing cable 114 is located below the component cable 112, the stabilizing cable 114 can enhance the ability of the photovoltaic support 100 to resist wind uplift.

[0105] For example, in some other embodiments, the load-bearing cable 113 and the stabilizing cable 114 can be in an X-shaped connection configuration.

[0106] In the photovoltaic support 100 provided by the embodiments of the present application, through the above settings of the load-bearing cable 113 and the stabilizing cable 114, the abilities of wind suction resistance and wind (snow) pressure resistance are effectively enhanced, the overall stiffness and torsional resistance of the photovoltaic support 100 are improved, and the deflection generated by the photovoltaic support 100 under the action of the load is reduced, thereby increasing the overall stability of the photovoltaic support 100.

[0107] In some embodiments, as Figures 1-6 shown, the main support structure may further include: an inter-cable support 115 and an inter-row strut 116.

[0108] The inter-cable support 115 can be supported between the component cable 112, the load-bearing cable 113, and the stabilizing cable 114; one end of the inter-row strut 116 can be connected to the inter-cable support 115, and the other end of the inter-row strut 116 can be used to connect to the inter-cable support 115 of another adjacent photovoltaic support 100.

[0109] The inter-cable support 115 can have various tie-rod configuration schemes such as an X shape or a triangle, without limitation here.

[0110] One or more inter-cable supports 115 can be provided, where "more than one" means two or more. For example, in some embodiments, as Figure 6 shown, eight inter-cable supports 115 are provided.

[0111] The row - spacing strut 116 can have various tie - rod form schemes such as X - type or triangular, and there is no limitation here.

[0112] One or more row - spacing struts 116 can be provided. Here, "more than one" means two or more. For example, in some embodiments, as Figure 6 shown, four row - spacing struts 116 are provided.

[0113] In actual implementation, the inter - cable support 115 can be provided with wire clips. The component cable 112, the load - bearing cable 113, and the stabilizing cable 114 can be connected to the inter - cable support 115 through corresponding wire clips. During the installation of the row - spacing strut 116, connection parts for fixing the connection can be provided on both the inter - cable support 115 and the row - spacing strut 116. The connection part at one end of the row - spacing strut 116 can be connected to the connection part of the inter - cable support 115 of one of the photovoltaic supports 100 through threaded connection or other connection methods, and the connection part at the other end of the row - spacing strut 116 can be connected to the connection part of the inter - cable support 115 of another photovoltaic support 100 through threaded connection or other connection methods. After installation, the row - spacing strut 116 can play an auxiliary support role between two adjacent photovoltaic supports 100.

[0114] The photovoltaic support 100 provided by the embodiment of the present application forms a photovoltaic support 100 phalanx system by connecting the component cable 112, the load - bearing cable, and the stabilizing cable 114 through the inter - cable support 115, increasing the stiffness of the photovoltaic support 100 in the up - and - down directions, effectively controlling the overall upward displacement of the suspension cable system and reducing the cable diameter. At the same time, by using the row - spacing strut 116, a mutual - support relationship is formed between adjacent photovoltaic supports 100, which can increase the anti - overturning performance of the photovoltaic support 100 and effectively improve the reliability and stability of the photovoltaic support 100.

[0115] In some embodiments, as Figures 1-2 shown, the main support structure can further include: a second auxiliary cable 117.

[0116] The second auxiliary cable 117 can be connected between the first support members 111.

[0117] The second auxiliary cable 117 can adopt any one or a combination of multiple types such as steel strands, steel ropes, steel cables, steel wires, or steel chains.

[0118] For example, in some embodiments, the second auxiliary cable 117 adopts a steel strand.

[0119] The second auxiliary cable 117 can have various connection form schemes such as X - type or fish - belly type, and there is no limitation here.

[0120] For example, in some embodiments, as Figures 1-2 shown, the second auxiliary cable 117 has an X - type connection form.

[0121] It should be noted that based on the second auxiliary cable 117, multiple connection form schemes can be selected, and some connection form schemes require the use of the inter-cable support 115 to assist in forming.

[0122] For example, in some embodiments, when the second auxiliary cable 117 has a parallel suspension cable structure, the second auxiliary cable 117 does not need to be connected to the inter-cable support 115.

[0123] Also, for example, in some other embodiments, as Figure 6 shown, when the second auxiliary cable 117 has an X-shaped connection form, the inter-cable support 115 can be supported between the component cable 112, the load-bearing cable 113, the stabilizing cable 114, and the second auxiliary cable 117.

[0124] The photovoltaic support 100 provided by the embodiment of the present application, by adding a second auxiliary cable 117 on the basis of the original component cable 112, load-bearing cable 113, and stabilizing cable 114, is used to improve the overall stiffness and strength of the photovoltaic support 100, further enhance the wind (snow) pressure resistance and wind uplift resistance of the photovoltaic support 100, and increase the use width of the photovoltaic support 100.

[0125] The present application also discloses a photovoltaic power generation system.

[0126] In some embodiments, the photovoltaic power generation system includes: a photovoltaic module and any one of the photovoltaic supports 100 as described above.

[0127] The photovoltaic module is installed on the photovoltaic support 100.

[0128] In actual implementation, the photovoltaic module may include a plurality of photovoltaic panels extending and laid along the first direction, and the photovoltaic module can be connected to the component cable 112, the weighing cable, and the stabilizing cable 114 by bolts or other connection methods.

[0129] The photovoltaic power generation system provided by the embodiment of the present application, through the setting of the above-mentioned photovoltaic support 100, effectively shares the horizontal force caused by the super-large-span flexible support structure in the middle, reduces the force on the first support member 111, thereby reducing the component size of the first support member 111, and further facilitating the fabrication, transportation, and construction of the first support member 111 and its joints. Without increasing the size and quantity of the pile foundation and the overall cost, the numerous pile foundations originally concentrated within the large-span range are dispersed to the large-span and small-span ranges, significantly alleviating the pile-soil squeezing effect, reducing the pile top elevation error caused by the squeezing effect during the later pile foundation construction, and at the same time improving the bearing capacity of the pile foundation, thereby enhancing the stability of the entire photovoltaic support 100.
