Description

Technical Field

[0001] The present invention relates to the technical field of flexible photovoltaic brackets, and in particular to a flexible photovoltaic component protection structure and an installation method. Background Art

[0002] Traditional fixed photovoltaic brackets are densely installed on the ground through brackets like crops in the fields. Although they can convert solar energy into electrical energy, they also make the comprehensive utilization rate of land low and cannot make the land play a greater role. Therefore, in order to improve land utilization, scientific researchers have found a new form of photovoltaic construction after a long period of exploration, moving photovoltaics from the ground to high altitudes. High-altitude photovoltaic arrays play a greater role in mountainous areas, and high-altitude photovoltaic panels use steel cables as supports. Under the condition of providing sufficient prestress, the flexible photovoltaic bracket with a suspension structure is not only easier to install, but also can withstand greater weight while completing large spans.

[0003] However, although the taut suspension cables have a certain rigidity, due to the large area of ​​the photovoltaic panels and the large wind resistance generated, the wind resistance in windy weather is still relatively weak. For example, the patent publication number CN220830405U discloses a protective structure for a flexible photovoltaic bracket, which has a four-cornered pyramid installed below the stabilizing cable for fixing the photovoltaic panel, and then two wind-proof cables perpendicular to each other are inserted at the bottom of the four-cornered pyramid to enhance the wind-proof effect of the flexible photovoltaic bracket.

[0004] By analyzing the existing technology, it is found that the flexible photovoltaic bracket still has the following defects: 1. Lack of buffer structure, easy to damage the photovoltaic components when the wind is too strong; 2. When the photovoltaic panel is subjected to wind blowing upward from the bottom, due to the different wind strengths in the middle and edge parts, different areas of the windbreak cable are subjected to different forces, resulting in uneven force; 3. When the photovoltaic panel is subjected to wind blowing upward from the bottom, due to the large area of ​​the photovoltaic panel and the large wind resistance, simply relying on setting gaps between adjacent photovoltaic panels is not enough to unload the wind force. Summary of the invention

[0047] Embodiment 2: This embodiment provides a method for installing a flexible photovoltaic component, which is used to install a flexible photovoltaic component protection structure as described in the first embodiment.

[0048] A method for installing a flexible photovoltaic module comprises the following steps: S1, install two sets of support frames 1 on both sides of the foundation, so that the beams on the support frames 1 are parallel and symmetrical; S2, fixing the left and right ends of the stabilizing cable 2 on the two beams respectively by means of the cable tensioning fixtures, and tightening the stabilizing cable 2 by means of the cable tensioning fixtures; S3, the photovoltaic panels 3 are fixed in an array on the stabilizing cables 2, leaving gaps between adjacent photovoltaic panels 3; S4, fix the quadrangular pyramid 4 at the bottom of the stabilizing cable 2, vertically and alternately insert the windproof vertical cables 5 and the windproof horizontal cables 6 at the bottom of the quadrangular pyramid 4, fix the two ends of each windproof vertical cable 5 upward in the cable tensioning fixture on the support frame 1, and fix the two ends of each windproof horizontal cable 6 downward in the cable tensioning fixture on the foundation; S5, tighten the windproof vertical cable 5 and the windproof horizontal cable 6 through the suspension cable tensioning fixture until the wind shield 47 is parallel to the photovoltaic panel 3.

[0049] In summary, the flexible photovoltaic component protection structure and installation method divide the tetrahedron 4 into two upper and lower parts that can slide against each other. The upper four-sided frame 41 and the inclined column 42 are fixed on the stabilizing cable 2, and the lower column sleeve 43 and the top rod 44 are fixed on the windproof vertical cable 5 and the 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 on the inner side of the column sleeve 43 moves inward or outward in the cross tube 45. By arranging a spring between the top rod 44 and the cross tube 45, the relative sliding of the inclined column 42 and the column sleeve 43 is made elastic, so as to achieve the purpose of buffering when the wind is too strong. At the same time, when the wind force in different areas is different, the upper half of the tetrahedron 4 can keep the bottom windproof vertical cable 5 and the windproof horizontal cable 6 straight by sliding different distances, so as to avoid uneven force affecting the service life.

[0050] The flexible photovoltaic component protection structure and installation method are characterized by arranging a windshield 47 in the tetrahedron 4. The windshield 47 is parallel to the photovoltaic panel 3 under normal conditions. When subjected to horizontal wind force, the tetrahedron 4 is parallel to the wind direction and will not increase wind resistance. When subjected to downward wind force, the windshield 47 is hidden at the bottom of the photovoltaic panel 3 and will 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 driven by the inclined column 42. The sliding column 472 can drive the tail of the windshield 47 near the aisle to swing upward and the end near the middle position of the tetrahedron 4 to swing downward. The inclined windshield 47 can guide the wind to the aisle position, thereby reducing the wind force on the photovoltaic panel 3.

[0051] The flexible photovoltaic component protection structure and installation method are characterized by providing a connecting plate 7 between two adjacent tetrahedrons 4, wherein one end of the connecting plate 7 is rotatably connected to a column sleeve 43 in one tetrahedron 4 near the aisle, and the other end is fixed to a column sleeve 43 in another tetrahedron 4 near the aisle by bolts, so that two adjacent rows of tetrahedrons 4 are connected together by the connecting plate 7 to enhance wind resistance.

[0052] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
