Description

Technical Field

[0001] This invention relates to the fields of photovoltaic power generation and building structure technology, and in particular to a flexible support photovoltaic corridor with a strut arch structure. Background Technology

[0002] Photovoltaic power generation, based on the photovoltaic effect, directly converts solar energy into electrical energy using photovoltaic modules. This is the primary method of solar power generation. Due to the low energy density of solar energy, photovoltaic power generation systems require a huge land area. As the installed capacity of photovoltaic power plants expands year by year, land resources for photovoltaic power generation are becoming increasingly scarce. Currently, in some relatively favorable mountainous, desert, and plain areas, the construction of photovoltaic power plants mainly relies on fixed rigid steel supports. Fixed rigid steel supports are lightweight steel frame structures with limited spanning capacity, generally less than 10 meters. This makes them difficult to implement in deep water surfaces or fishponds, in mountainous areas with large undulations, and in some hilly areas with fragmented terrain. In narrow, elongated terrain such as roads and ditches, if fixed rigid steel supports are used to construct photovoltaic power plants, firstly, it is impossible to cross the narrow terrain in one go; foundations and column supports need to be built within the plot, affecting the use of space under the panels. Secondly, a relatively dense arrangement of foundations and column supports is still required along both banks of the ditch.

[0003] In recent years, cable-stayed flexible photovoltaic (PV) supports have emerged. Single-layer cable structures typically have a longitudinal span of up to 25m, while cable truss structures can reach 50m. However, the cables in these supports require anchorage at their ends, and the prestressed internal forces are significant, necessitating large anchorage foundations. Therefore, continuous multi-span structures are often used to reduce the proportion of anchorage foundation work, thus improving the structure's economic efficiency. Existing flexible PV support technologies have only increased the longitudinal span of the supports, but not the lateral span between rows. While cable-stayed flexible PV supports can span the width of narrow, elongated terrain such as roads and ditches in a single operation due to their large longitudinal span, continuous multi-span spans are not feasible along the width, resulting in a large proportion of cable side anchorages and poor project economics. Furthermore, existing cable-stayed flexible supports have relatively small lateral spans between rows, requiring dense foundations and column supports along the banks of ditches, which also impacts the space beneath the slabs. Therefore, there is an urgent need to address the challenge of increasing the lateral span of flexible PV supports. Summary of the Invention

[0004] In view of this, the present invention provides a flexible support photovoltaic corridor with a strut arch structure, which spans a narrow strip of terrain in the horizontal direction with a single span and has a continuous multi-span structure in the length direction, realizing land-saving photovoltaic power generation through the composite use of land space.

[0005] This invention is achieved through the following technical solution: a flexible support photovoltaic corridor with a strut arch structure, comprising load-bearing cables, double-arch side beam structures, single-arch central beam structures, diagonal tie rods, side columns, central columns, ground anchor foundations, and photovoltaic modules; two sets of double-arch side beam structures are located at the beginning and end of the structure, respectively, and each spans the width of the narrow terrain in a single transverse span. Each set of double-arch side beam structures is supported on the ground at both ends by side columns and is fixed to the ground by diagonal tie rods; the load-bearing cables extend along the length of the narrow terrain, with both ends connected to the two sets of double-arch side beam structures, and prestress is applied to the cables; within the span of the two sets of double-arch side beam structures along the length of the narrow terrain, several sets of single-arch central beam structures supported by central columns are installed, each single-arch central beam structure spanning the width of the narrow terrain in a single transverse span to support the load-bearing cables; the photovoltaic modules are installed on the load-bearing cables via clips.

[0006] Furthermore, the double-arch side beam structure includes a side beam, arched cables, arched rods, horizontal struts, vertical struts, and tie rods. The side beam is set parallel to the width of the narrow plot, and its top is anchored to the end of the load-bearing cable. The inner side of the side beam is fixed to several horizontal struts, which are parallel to the load-bearing cable. The line connecting the ends of the horizontal struts forms an arch, and the ends of the horizontal struts abut against the arched cables. The ends of the arched cables are fixed to both ends of the side beam, and prestress is applied to the arched cables. The side beam, arched cables, and horizontal struts... The horizontal struts form a horizontal strut arch structure to bear tensile forces. The bottom of the side beam is fixed to several vertical struts, which correspond to the horizontal struts and are perpendicular to each other. The ends of the vertical struts are connected in an arch shape, and the ends of the vertical struts are rotatably connected to the arched struts. The ends of the arched struts are fixed to both ends of the side beam. The side beam, the arched struts, and the vertical struts form a vertical strut arch structure to bear compressive forces. The horizontal strut arch structure and the vertical strut arch structure are connected by tie rods to form a double-tied arch side beam structure.

[0007] Furthermore, the single-arch beam structure includes a central beam, vertical struts of the central beam, and arched struts of the central beam; the central beam is parallel to the side beams, the bottom of the central beam is fixedly connected to several vertical struts of the central beam, and the vertical struts of the central beam are perpendicular to the central beam; the line connecting the ends of the vertical struts of the central beam is arched, the ends of the vertical struts of the central beam are rotatably connected to the arched struts of the central beam, and the ends of the arched struts of the central beam are fixedly connected to both ends of the central beam.

[0008] Furthermore, the end of the horizontal support rod is provided with an arc-shaped notch to form a saddle that abuts against the arched cable; the other end of the horizontal support rod is connected to the welding plate on the side of the side beam through the horizontal support rod base plate by fasteners, and the top of the horizontal support rod base plate is provided with a fan-shaped notch for the load-bearing cable to pass through.

[0009] Furthermore, the lengths of both the horizontal and vertical struts are controlled by the arch equation, which is as follows: In the formula: y is the length of the horizontal strut or the length of the vertical strut, h is the arch height at the arch crown position, l is the arch span, and x is the distance from the horizontal strut or the vertical strut to the arch foot.

[0010] Furthermore, it also includes an inverted V-shaped stabilizing cable, a V-shaped stabilizing cable, and a stabilizing rod installed below the surface of the load-bearing cable; the inverted V-shaped stabilizing cable and the V-shaped stabilizing cable are installed opposite each other in the longitudinal single span, and the open ends of the inverted V-shaped stabilizing cable and the V-shaped stabilizing cable are respectively fixed to the double-arch side beam structure or the single-arch middle beam structure, and the main bodies of the inverted V-shaped stabilizing cable and the V-shaped stabilizing cable are obliquely connected to the load-bearing cable through damping springs; the stabilizing rod is parallel to the side beam and is installed in the middle of the longitudinal single span, the stabilizing rod body is connected to the load-bearing cable, and the two ends of the stabilizing rod are respectively connected to the closed end of the inverted V-shaped stabilizing cable and the closed end of the V-shaped stabilizing cable.

[0011] Furthermore, the position of the connection point between the horizontal strut and the side beam corresponds to the position of the connection point between the load-bearing cable and the side beam; the position of the connection point between the vertical strut of the middle beam and the middle beam corresponds to the position of the contact point between the load-bearing cable and the side beam.

[0012] Furthermore, the tie rod is anchored to the ground at an angle downwards in a figure-eight shape.

[0013] Compared with existing technologies, the beneficial effects of this invention are: 1. This invention significantly enhances the lateral spanning capacity of flexible photovoltaic support structures through a double-arch side beam structure and a single-arch center beam structure, enabling them to cross narrow strip-shaped plots in one go. At the same time, it leverages the advantages of long longitudinal spans to form a continuous multi-span structure, creating a photovoltaic corridor for the construction of photovoltaic power stations. This reduces the amount of steel used in the structure and the number of foundations, improves the economic efficiency of the project, and does not affect the use of the space under the panels.

[0014] 2. This invention improves the spanning capacity of the side beams and middle beams through horizontal strut arch structures and vertical strut arch structures, enabling single-pass crossing of strip terrain such as roads, avoiding the need to construct foundations and columns in narrow plots, and greatly reducing the number of foundations and columns.

[0015] 3. The flexible support structure of this invention improves the wind resistance and vibration reduction capability of the structure through the synergistic effect of inverted V-shaped stabilizing cables, V-shaped stabilizing cables, stabilizing rods and damping springs.

[0016] 4. The tie rod of this invention extends outward in a figure-eight shape and is anchored to the ground at an angle downward. It can effectively bear the internal force of the arched cable, reduce the axial compression load on the side beam, and further reduce the amount of steel used in the structure.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] This invention provides a flexible photovoltaic corridor with a strut-arch structure. The double-arch side beam structure increases the lateral span of the flexible photovoltaic support, enabling it to cross the width of narrow strips of land such as roads and ditches in one go. It also leverages the long-span advantage of the flexible photovoltaic support, allowing for the continuous arrangement of multi-span flexible support structures along the length of the narrow strip to construct an elevated photovoltaic power station. For example... Figure 1 As shown, the flexible support photovoltaic corridor of the strut arch structure includes load-bearing cables 1, double-arch side beam structure 2, diagonal tie rods 3, single-arch middle beam structure 4, side columns 5, middle columns 6, multi-pile foundation anchor foundation 7, and photovoltaic modules 13.

[0027] Two sets of double-arch side beam structures 2 are located at the beginning and end of the plot, respectively, and each spans the width of the narrow plot in a single transverse span. The bottom of each set of double-arch side beam structures 2 is supported on the ground on both sides of the narrow plot by two side columns 5. The sides of each end of the double-arch side beam structure 2 are connected to the multi-pile foundation anchor 7 by two diagonal tie rods 3, and anchored to the ground on both sides of the narrow plot. Several sets of load-bearing cables 1 (each set includes two load-bearing cables 1, and the two load-bearing cables 1 in the same set support the same photovoltaic module 13) are evenly distributed along the width of the narrow plot and extend along the length of the narrow plot. The two ends of the load-bearing cables 1 are connected to the two sets of double-arch side beam structures 2, respectively. Photovoltaic modules 13 are installed on each set of load-bearing cables 1 by snap-fit. When the load-bearing cables 1 are installed on the two sets of double-arch side beam structures 2, prestress is applied to the load-bearing cables 1 to give them stress stiffness so that they can support the photovoltaic modules 13 across narrow strips of land such as roads, ditches, and rivers, and build photovoltaic power stations in the air to form a photovoltaic corridor.

[0028] The prestress applied to the load-bearing cable 1, its own weight, and the increased internal force under wind and snow loads are borne by the double-arch side beam structures 2 at both ends, and transferred to the ground through the side columns 5 and the tie rods 3 connected to the multi-pile foundation anchor 7. The internal force F of the load-bearing cable 1, generated by its own weight and the increase under wind and snow loads, is proportional to the square of the single longitudinal span distance L, as shown in the following formula: (1) In the formula: F is the internal force of the cable, q is the line load generated on the cable 1 by its own weight and wind and snow loads, L is the single longitudinal span of the cable 1, and f is the deflection of the cable 1 under the load.

[0029] Therefore, the single longitudinal span distance L should not be too large. So along the length of the narrow plot, within the longitudinal span of the two sets of double-arch side beam structures 2, several single-arch middle beam structures 4 supported by central columns 6 are set up. The single-arch middle beam structures 4 are used to support the load-bearing cables 1. The single-arch middle beam structures 4 all cross the width of the narrow plot in a single transverse span. The two sets of double-arch side beam structures 2 and the single-arch middle beam structures 4 between their spans form a continuous multi-span structure.

[0030] like Figure 2As shown, the double-arch side beam structure 2 mainly consists of side beam 2.1, arched cable 2.2, arched rod 2.3, horizontal strut 2.4, vertical strut 2.5, and tie rod 2.6. Side beam 2.1 is parallel to the width of the narrow plot, and the top of side beam 2.1 is anchored to the end of load-bearing cable 1. Specifically, load-bearing cable 1 consists of steel strand 1.1 and wedge anchor 1.2. Steel strand 1.1 passes through wedge-shaped anchor plate 2.1.1 welded to the top of side beam 2.1 and is anchored using wedge anchor 1.2. After tensioning steel strand 1.1 to the specified prestress using a through-hole jack, wedge anchor 1.2 clamps steel strand 1.1 and supports it on wedge-shaped anchor plate 2.1.1.

[0031] The load-bearing cable 1 generates a horizontal tensile force Fh and a vertical pull-out force or downward compressive force Fv1 at the connection node of the double-tied arch side beam structure 2 at both ends. The calculation formula for Fv1 generated at the connection node of side beam 2.1 is as follows: (2) In the formula: Fv1 is the vertical pull-out force or downward pressure generated by the load-bearing cable 1 at the connection node of the two sets of double-tied arch side beam structures 2; when calculating the downward pressure, q v1 When calculating the pull-out force q, consider the self-weight of cable 1 and the downward pressure load generated on the cable by wind, snow, and other loads. v1 The upward line load generated on the cable after subtracting the self-weight of the load-bearing cable 1 from the upward wind load; L is the single longitudinal span of the load-bearing cable 1.

[0032] The side beam 2.1, arched cable 2.2, and horizontal strut 2.4 constitute a horizontal strut arch structure. The horizontal tension Fh is borne by the horizontal strut arch structure and transmitted to the ground by the diagonal tie rods 3 connected to both ends of the side beam 2.1. Specifically, as... Figure 3 As shown, the inner side of the side beam 2.1 (the side facing each other of the two sets of double-tied arch side beam structures 2.1 is the inner side) is fixedly connected to several horizontal struts 2.4. The horizontal struts 2.4 are parallel to the load-bearing cable 1. The connection point between the horizontal struts 2.4 and the side beam 2.1 is as close as possible to the connection point between the load-bearing cable 1 and the side beam 2.1. Preferably, the positions of the several horizontal struts 2.4 correspond to the positions of the load-bearing cable 1. Several horizontal struts 2.4 of varying lengths are connected at their ends in an arched shape. One end of each horizontal strut 2.4 has an arc-shaped notch forming a saddle 2.4.2 that abuts against the arched cable 2.2. The ends of the arched cable 2.2 are fixed to both ends of the side beam 2.1. The other end of the horizontal strut 2.4 is welded to the middle of the horizontal strut base plate 2.4.1 with a fan-shaped notch at the top, and is connected to the welded plate on the side of the side beam 2.1 by bolts. The fan-shaped notch of the horizontal strut base plate 2.4.1 is used for the passage of the load-bearing cable 1.

[0033] Two ends of the arch-shaped cable 2.2 are anchored on the side beams 2.1 respectively, and prestress is applied to the arch-shaped cable 2.2, so that most of the horizontal pulling force Fh is transmitted to the arch-shaped cable 2.2 via the horizontal strut 2.4, whereby only a small part of the horizontal pulling force Fh is distributed to the side beams 2.1. The side beams 2.1 mainly bear pressure, and the bending moment borne by the beam body is relatively small. All rods in the horizontal strut arch structure bear pulling force, forming an integral tension structure, which can give full play to material properties to the greatest extent and save the steel consumption of the structure.

[0034] The side beam 2.1, the arch-shaped rod 2.3 and the vertical strut 2.5 form a vertical strut arch structure. The vertical upward pulling force or downward pressure Fv1 is borne by the vertical strut arch structure, and transmitted to the ground by side columns 5 supported at two ends of the side beam 2.1. Specifically, the bottom of the side beam 2.1 is fixedly connected with a plurality of vertical struts 2.5, the positions of the plurality of vertical struts 2.5 correspond to the positions of the horizontal struts 2.4, and the vertical struts 2.5 are perpendicular to the horizontal struts 2.4. The plurality of vertical struts 2.5 have different lengths, and the connecting line of the ends thereof is arch-shaped, wherein a welded ear plate 2.5.2 at the end of the vertical strut 2.5 is rotatably connected with the rod body of the arch-shaped rod 2.3 through a pin shaft; ends of the arch-shaped rod 2.3 are respectively fixedly connected to two ends of the side beam 2.1. In specific implementation, the bearing points of connection points of the side beam 2.1 with the diagonal draw bar 3, the side column 5, the arch-shaped rod 2.3 and the arch-shaped cable 2.2 are arranged at one position, which facilitates force transmission; the other end of the vertical strut 2.5 is welded with a vertical strut bottom plate 2.5.1, which is connected with a welded plate at the bottom of the side beam 2.1 through bolts. The arch-shaped rod 2.3 is assembled from a plurality of sections of prefabricated arched beams into a continuous arch structure through flange nodes, which adopts modular design and is convenient for transportation and on-site assembly. The vertical strut bottom plate 2.5.1 and the horizontal strut bottom plate 2.4.1 can be of a factory-shaped folded surface structure. The plane part of the horizontal strut bottom plate 2.4.1 is in vertical butt joint with the welded plate on the side surface of the side beam 2.1, and the plane part of the vertical strut bottom plate 2.5.1 is in horizontal butt joint with the welded plate on the bottom surface of the side beam 2.1, that is, the plane part of the horizontal strut bottom plate 2.4.1 and the plane part of the vertical strut bottom plate 2.5.1 are perpendicular to each other, and the inclined surface part of the horizontal strut bottom plate 2.4.1 and the inclined surface part of the vertical strut bottom plate 2.5.1 are bonded, butted with each other and fixedly connected by using a fastener.

[0035] The downward pressure Fv1 borne by the vertical strut arch structure under dead weight and downward wind load is compressed by the vertical strut 2.5 and transmitted to the arch-shaped rod 2.3 to bear tension, so that only a small part of the downward pressure Fv1 is distributed to the side beam 2.1, and the bending moment borne by the beam body is relatively small; the upward pulling force Fv1 borne by the structure under the action of upward wind load is tensioned by the vertical strut 2.5 and transmitted to the arch-shaped rod 2.3 to bear pressure, so that only a small part of the upward pulling force Fv1 is also distributed to the side beam 2.1, and the bending moment borne by the beam body is relatively small. All rods in the vertical strut arch structure bear pressure, forming an integral tension structure, which can give full play to material properties to the greatest extent and save the steel consumption of the structure.

[0036] In addition, the horizontal and vertical strut arch structures are connected by tie rods 2.6. The two ends of tie rod 2.6 are connected to the ends of vertical strut 2.5 and horizontal strut 2.4 respectively via pins, forming a triangular stabilizing system and increasing structural stability. Tie rods 2.6, the horizontal and vertical strut arch structures together constitute the double-tied arch side beam structure 2. The double-tied arch side beam structure 2 allows for a single transverse span across a narrow plot of land, without requiring any foundations or column supports in the space beneath the slab, thus not affecting the normal use of the space.

[0037] In the double-arch side beam structure 2, the lengths of the horizontal strut 2.4 and the vertical strut 2.5 are controlled by the arch equation, which is as follows: (3) In the formula: y is the arch height of the arch line, that is, the length of the horizontal strut 2.4 or the length of the vertical strut 2.5; h is the arch height at the top of the arch line; l is the arch span, that is, the distance between the two arch feet; x is the distance from the horizontal strut 2.4 or the vertical strut 2.5 to the arch foot.

[0038] The load-bearing cable 1 is supported by the single-arch central beam structure 4 in the longitudinal span of the two sets of double-arch side beam structures 2, and the load-bearing cable 1 abuts against the single-arch central beam structure 4 along the length direction. Specifically, as shown... Figure 4 As shown, the single-arch beam structure 4 consists of a central beam 4.1, vertical struts 4.2, and arched members 4.3. Their connection relationships and force-bearing principles are consistent with those of the side beams 2.1, arched members 2.3, and vertical struts 2.5. In other words, the central beam 4.1, vertical struts 4.2, and arched members 4.3 also constitute a vertical strut arch structure. The central beam 4.1 is parallel to the side beam 2.1. The bottom of the central beam 4.1 is fixedly connected to several vertical struts 4.2. The positions of these vertical struts 4.2 preferably correspond to the contact points between the load-bearing cable 1 and the central beam 4.1. The vertical struts 4.2 are perpendicular to the central beam 4.1. Several vertical struts 4.2 of the central beam have different lengths and their ends are connected in an arch shape. The ends of the vertical struts 4.2 of the central beam are rotatably connected to the arched struts 4.3 of the central beam by a pin. The ends of the arched struts 4.3 of the central beam are fixed to both ends of the central beam 4.1. The other end of the vertical struts 4.2 of the central beam is welded to a base plate, which is connected to the welded plate at the bottom of the central beam 4.1 by bolts.

[0039] The horizontal tension Fh on both sides of the connection node between the load-bearing cable 1 and the single-arch beam 4 is balanced, and the vertical pull force or downward pressure Fv2 is generated only at the connection node of the beam 4.1. The calculation formula for Fv2 generated at the connection node of the beam 4.1 is as follows.

[0040] (4) In the formula: Fv2 is the vertical pull-out force or downward pressure generated by the connection node of the middle beam 4.1; when calculating the downward pressure, q v2When calculating the pull-out force q, consider the self-weight of cable 1 and the downward pressure load generated on the cable by wind, snow, and other loads. v2 The upward wind load is calculated by subtracting the upward line load generated on the cable by the self-weight of the load-bearing cable 1; L1 is the single span of the load-bearing cable 1 on the left side of the single-arch beam structure 4; L2 is the single span of the load-bearing cable 1 on the right side of the single-arch beam structure 4.

[0041] The vertical uplift force or downlift force Fv2 of the single-arch central beam structure 4 is borne by the vertical strut arch structure and transmitted to the ground by the central columns 6 connected to both ends of the vertical strut arch structure. The downlift force Fv2 borne by the single-arch central beam structure 4 under its own weight and the downward wind load is compressed by the vertical strut 4.2 and transmitted to the central beam arch member 4.3 under tension, so that the side beam 4.1 only receives a small portion of the downlift force Fv2 and the beam body experiences a small bending moment; the uplift force Fv2 borne by the structure under the upward wind load is tensioned by the central beam vertical strut 4.2 and transmitted to the central beam arch member 2.3 under compression, so that the central beam 4.1 also only receives a small portion of the uplift force Fv2 and the beam body experiences a small bending moment.

[0042] To enhance the overall integrity of the multi-row load-bearing cables 1 and improve the wind vibration stability of the single-row photovoltaic modules 13 under wind loads, and to dissipate the horizontal wind kinetic energy perpendicular to the load-bearing cables 1, a stabilizing component is installed below the surface of the load-bearing cables 1 after the photovoltaic modules 13 are installed. Figure 5 As shown, the stabilizing component includes an inverted V-shaped stabilizing cable 8, a V-shaped stabilizing cable 9, and a stabilizing rod 10. The inverted V-shaped stabilizing cable 8 and the V-shaped stabilizing cable 9 are both connected to the load-bearing cable 1, and the stabilizing rod 10 is set at the mid-span of the longitudinal section and connected to the load-bearing cable 1, the inverted V-shaped stabilizing cable 8, and the V-shaped stabilizing cable 9. Among them, the inverted V-shaped stabilizing cable 8 and the V-shaped stabilizing cable 9 are set opposite each other in the longitudinal single span of the double-arch side beam structure 2 or the single-arch middle beam structure 4. The open ends of the two are fixed to the side beam 2.1 or the middle beam 4.1 of the single span, respectively. The main body of the inverted V-shaped stabilizing cable 8 and the V-shaped stabilizing cable 9 are obliquely connected to each group of load-bearing cables 1 through two damping springs 11. The stabilizing rod 10 is located in the middle of the longitudinal single span and is set parallel to the side beam 2.1 and the middle beam 4.1. The stabilizing rod 10 is connected to each group of load-bearing cables 1 through angle steel connectors 12. The two ends of the stabilizing rod 10 are connected to the closed ends of the inverted V-shaped stabilizing cable 8 and the V-shaped stabilizing cable 9, respectively. The stabilizing rod 10 enhances the integrity of the multi-row structure of the load-bearing cables 1 and can transmit wind force from different directions to the inverted V-shaped stabilizing cables 8 and the V-shaped stabilizing cables 9 for dissipation. Specifically, when the wind blows from the open end of the V-shaped stabilizing cable 9 to its closed end (such as... Figure 6 As shown, (north wind), the traction damping spring 11 of the photovoltaic module 13 extends, causing the V-shaped stabilizing cable 9 to be taut and resist the north wind, dissipating wind kinetic energy; when the wind blows from the open end of the inverted V-shaped stabilizing cable 8 to its closed end (as shown), Figure 6As shown, (south wind), the photovoltaic module 13 traction damping spring 11 extends, the inverted V-shaped stabilizing cable 8 is stretched, resisting the action of the south wind and dissipating the wind kinetic energy.

[0043] When the construction site is unrestricted and the geological conditions are good, the tie rod 3 should extend outward in a figure-eight shape on the plane and be anchored to the ground at an angle downward. This can effectively bear the internal force of the arched cable 2.2 of the double-arch side beam structure 2, reduce the axial compression load borne by the side beam 2.1, and further reduce the amount of steel used in the structure.

[0044] This invention can be applied to different regions. Based on the solar altitude angle in different regions, the installation angle of the photovoltaic module 13 can be adjusted by changing the height difference between the two load-bearing cables 1, allowing the photovoltaic module 13 to achieve the optimal power generation angle. This invention can be applied to linear areas such as roads, ditches, and rivers, where several longitudinal continuous spans are set according to the terrain length to form a photovoltaic corridor; it can also be applied to block-shaped areas such as industrial parks, fishponds, and pastures, where several transverse continuous arches are added according to the terrain and open space to form a large-area photovoltaic array with a multi-arch, multi-span structure. The internal force and span of the load-bearing cables 1 of this invention should be determined by calculation based on the wind pressure of the area and the type of photovoltaic module 13; the specific form and size of the ground anchors and column foundations should be specifically calculated based on the wind pressure, site layout, span, and geological parameters of the specific area. The height of the photovoltaic support above the ground can be adjusted according to the function of the space under the panel, allowing sufficient clearance to be reserved without affecting the land use function.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
