Description

Technical Field

[0001] This invention relates to the field of flexible photovoltaic support technology, specifically to a protective structure and installation method for flexible photovoltaic modules. Background Technology

[0002] Traditional fixed photovoltaic (PV) systems are like crops in a field, densely packed together on the ground. While they convert solar energy into electricity, they also result in low land utilization and fail to maximize the land's potential. To improve land utilization, researchers have explored new PV installation methods, moving PV from the ground to the air. These high-altitude PV arrays are particularly effective in mountainous regions. The high-altitude PV panels are supported by steel cables. With sufficient prestress, the flexible suspension structure of the PV system is not only easier to install but can also withstand greater weight while spanning large distances.

[0003] However, although the taut suspension cable has a certain rigidity, the large area of ​​the photovoltaic panel generates a large wind resistance, and its wind resistance performance in windy weather is still relatively weak. For example, patent publication number CN220830405U discloses a protective structure for a flexible photovoltaic support. It also installs a four-corner pyramid below the stabilizing cable used to fix the photovoltaic panel, and inserts two mutually perpendicular windproof cables at the bottom of the four-corner pyramid to enhance the windproof effect of the flexible photovoltaic support.

[0004] Analysis of existing technologies reveals the following defects in flexible photovoltaic (PV) mounting systems: 1. Lack of a buffer structure, making PV modules susceptible to damage in strong winds; 2. Uneven stress distribution due to varying wind forces between the middle and edge sections of the PV panel when subjected to upward-blowing winds; 3. High wind resistance due to the large area of ​​the PV panel, making it insufficient to simply create gaps between adjacent panels to dissipate the wind force. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a flexible photovoltaic module protective structure and installation method, which has the advantage of strong wind resistance and solves the problems mentioned in the background technology.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A flexible photovoltaic module protection structure includes a support frame, a stabilizing cable fixed on the support frame, a photovoltaic panel fixed above the stabilizing cable, and a four-corner pyramid fixed below the stabilizing cable. The bottom of the four-corner pyramid is pierced by mutually perpendicular vertical and horizontal windproof cables. The four-corner pyramid comprises:

[0010] The four-sided frame is fixed at the top under the stabilizing cable, and has four symmetrical inclined columns at the bottom. The top of the inclined columns is fixed to the bottom of the four-sided frame, and the bottom of the inclined columns is inclined towards the middle of the four-cornered pyramid.

[0011] Each inclined column is slidably connected to a column sleeve on its outer side, and each column sleeve has a top rod fixed at its bottom, pointing towards the center of the four-cornered pyramid.

[0012] The cross tube consists of four hollow tubes. The push rod is inserted into the corresponding hollow tube and slides. A spring is also provided between the hollow tube and the push rod.

[0013] The base plate is fixed to the bottom of the cross tube. Below the base plate are vertical cable fixing rings and horizontal cable fixing rings for passing through the windproof vertical cable and windproof horizontal cable respectively.

[0014] Preferably, each row of photovoltaic panels has a stabilizing cable group consisting of at least two stabilizing cables fixed at its bottom. The gap between two adjacent stabilizing cable groups forms a passageway. In any quadrangular pyramid, the two inclined columns closest to the same passageway form one inclined column group, and the remaining two inclined columns form another inclined column group. At least one windbreak plate is installed on one inclined column group, and the same number of symmetrical windbreak plates are installed on the other inclined column group. The windbreak plates include:

[0015] The rotating column is rotatably connected to the rotating shaft hole on the column sleeve;

[0016] Wind deflector tail groove, wherein the wind deflector tail groove is provided at the tail of the wind deflector, and the end of the wind deflector extends toward the middle of the four-cornered pyramid;

[0017] A sliding column is provided in the tail groove of the wind deflector. The left and right ends of the sliding column are inserted into the lifting holes provided on the inclined column. The column sleeve is provided with a column sleeve groove at the position of the corresponding sliding column.

[0018] Under normal conditions, the wind deflector is parallel to the photovoltaic panel. When the photovoltaic panel is blown upward by the wind, the photovoltaic panel drives the stabilizing cable, the four-sided frame and the inclined column to move upward relative to the column sleeve. The sliding column moves upward relative to the column sleeve under the action of the inclined column. The sliding column can cause the tail of the wind deflector near the passageway to swing upward and the end near the middle of the four-corner pyramid to swing downward. The inclined wind deflector can guide the wind to the passageway and reduce the wind force on the photovoltaic panel.

[0019] Preferably, the wind deflector tail groove is a sliding groove formed by fixing a tail groove pressure plate on the top surface of the wind deflector.

[0020] Preferably, one end of the spring is fixed to the end of the hollow tube, and the other end is fixed to the position where the top rod root connects to the column sleeve.

[0021] Preferably, the support frame includes an A-shaped support leg and a crossbeam set on the top of the support leg. The bottom of the support leg is fixed to the foundation, and a suspension cable tensioner is set on the crossbeam for fixing the stabilizing cable and for adjusting the tension of the suspension cable.

[0022] Preferably, the windproof vertical cable is parallel to the stabilizing cable, and both ends of the windproof vertical cable are fixed upwards in the suspension cable tensioning device on the support frame.

[0023] Preferably, both ends of the windproof cross cable are fixed downwards in a suspension cable tensioning device on the foundation.

[0024] Preferably, a connecting plate is provided between the four-corner pyramids below two adjacent sets of stabilizing cable groups. One end of the connecting plate is rotatably connected to a column sleeve inside a four-corner pyramid near the passageway, and the other end of the connecting plate is fixed to a column sleeve inside another four-corner pyramid near the passageway by bolts.

[0025] Preferably, a limit pin is provided on the inclined column at a position within the corresponding column sleeve groove to limit the range of sliding between the inclined column and the column sleeve.

[0026] A method for installing a flexible photovoltaic module includes the following steps:

[0027] S1, two sets of support frames are installed on both sides of the foundation to make the crossbeams on the support frames parallel and symmetrical;

[0028] S2, the left and right ends of the stabilizing cable are fixed on the two crossbeams by suspension cable tensioners, and the stabilizing cable is tightened by suspension cable tensioners;

[0029] S3, photovoltaic panels are fixed in an array on a stabilizing cable, with gaps between adjacent photovoltaic panels;

[0030] S4, fix a four-corner pyramid at the bottom of the stabilizing cable, and interweave the windproof vertical cable and windproof horizontal cable vertically and alternately at the bottom of the four-corner pyramid. Fix the two ends of each windproof vertical cable upward in the suspension cable tensioning device on the support frame, and fix the two ends of each windproof horizontal cable downward in the suspension cable tensioning device on the foundation.

[0031] S5, the windproof vertical cables and windproof horizontal cables are tightened to the point that the windbreak plate is parallel to the photovoltaic panel by means of the suspension cable tensioning and fixing device.

[0032] (III) Beneficial Effects

[0033] Compared with the prior art, the present invention provides a flexible photovoltaic module protective structure and installation method, which has the following beneficial effects:

[0034] 1. The flexible photovoltaic module protective structure and installation method divides the four-corner pyramid into two sliding parts. The upper four-sided frame and inclined column are fixed to the stabilizing cable, while the lower column sleeve and top rod are fixed to the windproof vertical cable and windproof horizontal cable through the cross tube. When the column sleeve slides relative to the inclined column, the top rod inside the column sleeve moves inward or outward within the cross tube. By setting a spring between the top rod and the cross tube, the relative sliding between the inclined column and the column sleeve is elastic, achieving the purpose of buffering when the wind force is too strong. At the same time, when different areas are subjected to different wind forces, the upper part of the four-corner pyramid can keep the bottom windproof vertical cable and windproof horizontal cable straight by sliding different distances, avoiding uneven force and affecting service life.

[0035] 2. The flexible photovoltaic module protective structure and installation method, by setting wind deflectors inside the four-corner pyramid, the wind deflectors are parallel to the photovoltaic panels under normal conditions. When subjected to horizontal wind force, the parallelism of the four-corner pyramids with the wind direction will not increase wind resistance. When subjected to downward wind force, the wind deflectors are hidden at the bottom of the photovoltaic panels and will not increase wind resistance. When subjected to upward wind force, the column sleeve is pulled downward by the windproof horizontal cable to maintain stability. The photovoltaic panel drives the stabilizing cable, the four-sided frame and the inclined column to move upward relative to the column sleeve. The sliding column moves upward relative to the column sleeve under the drive of the inclined column. The sliding column can drive the tail of the wind deflector near the passageway to swing upward and the end near the middle of the four-corner pyramid to swing downward. The inclined wind deflector can guide the wind to the passageway position and reduce the wind force on the photovoltaic panel.

[0036] 3. The flexible photovoltaic module protective structure and installation method involves setting a connecting plate between two adjacent quadrangular pyramids. One end of the connecting plate is rotatably connected to a column sleeve inside one quadrangular pyramid near the passageway, and the other end is fixed to a column sleeve inside another quadrangular pyramid near the passageway by bolts. This connects two adjacent rows of quadrangular pyramids together through the connecting plate, thereby enhancing wind resistance. Attached Figure Description

[0073] Example 2:

[0074] This embodiment provides a method for installing a flexible photovoltaic module, which is used to install a protective structure for a flexible photovoltaic module as described in Embodiment 1.

[0075] A method for installing a flexible photovoltaic module includes the following steps:

[0076] S1, two sets of support frames 1 are installed on both sides of the foundation to make the crossbeams on the support frames 1 parallel and symmetrical;

[0077] S2, fix the left and right ends of the stabilizing cable 2 on the two crossbeams respectively by the suspension cable tensioning and fixing device, and tighten the stabilizing cable 2 by the suspension cable tensioning and fixing device;

[0078] S3, photovoltaic panels 3 are fixed in an array on the stabilizing cable 2, with gaps between adjacent photovoltaic panels 3;

[0079] S4, fix the four-corner pyramid 4 at the bottom of the stabilizing cable 2, and vertically interweave the windproof vertical cable 5 and the windproof horizontal cable 6 at the bottom of the four-corner pyramid 4. Fix the two ends of each windproof vertical cable 5 upward in the suspension cable tensioning device on the support frame 1, and fix the two ends of each windproof horizontal cable 6 downward in the suspension cable tensioning device on the foundation.

[0080] S5, the windproof vertical cable 5 and windproof horizontal cable 6 are tightened to the point that the windbreak plate 47 is parallel to the photovoltaic panel 3 by means of the suspension cable tensioning and fixing device.

[0081] In summary, the flexible photovoltaic module protective structure and installation method divides the quadrangular pyramid 4 into two sliding parts. The upper quadrilateral frame 41 and inclined column 42 are fixed to the stabilizing cable 2, while the lower column sleeve 43 and top rod 44 are fixed to the windproof vertical cable 5 and windproof horizontal cable 6 through the cross tube 45. When the column sleeve 43 slides relative to the inclined column 42, the top rod 44 inside the column sleeve 43 moves inward or outward within the cross tube 45. By setting a spring between the top rod 44 and the cross tube 45, the relative sliding between the inclined column 42 and the column sleeve 43 is elastic, achieving the purpose of buffering when the wind force is too strong. At the same time, when different areas are subjected to different wind forces, the upper part of the quadrangular pyramid 4 can slide different distances to keep the bottom windproof vertical cable 5 and windproof horizontal cable 6 straight, avoiding uneven force and affecting service life.

[0082] The flexible photovoltaic module protective structure and installation method involves setting a windbreak plate 47 inside the quadrangular pyramid 4. Under normal conditions, the windbreak plate 47 is parallel to the photovoltaic panel 3. When subjected to horizontal wind force, the quadrangular pyramid 4 is parallel to the wind direction and does not increase wind resistance. When subjected to downward wind force, the windbreak plate 47 is hidden at the bottom of the photovoltaic panel 3 and does not increase wind resistance. When subjected to upward wind force, the column sleeve 43 is pulled downward by the windproof horizontal cable 6 to maintain stability. The photovoltaic panel 3 drives the stabilizing cable 2, the four-sided frame 41 and the inclined column 42 to move upward relative to the column sleeve 43. The sliding column 472 moves upward relative to the column sleeve 43 under the drive of the inclined column 42. The sliding column 472 can drive the tail of the windbreak plate 47 near the passageway to swing upward and the end near the middle of the quadrangular pyramid 4 to swing downward. The inclined windbreak plate 47 can guide the wind to the passageway position and reduce the wind force on the photovoltaic panel 3.

[0083] The flexible photovoltaic module protective structure and installation method connects two adjacent quadrangular pyramids 4 by setting a connecting plate 7 between them. One end of the connecting plate 7 is rotatably connected to a column sleeve 43 near the passageway inside one quadrangular pyramid 4, and the other end is fixed to a column sleeve 43 near the passageway inside another quadrangular pyramid 4 by bolts. This connects two adjacent rows of quadrangular pyramids 4 together through the connecting plate 7, thereby enhancing wind resistance.

[0084] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
