Photovoltaic power generation systems that utilize solar energy have advantages such as being green and environmentally friendly, having abundant resources, and being stable. However, photovoltaic power generation systems require photovoltaic brackets to support and fix the photovoltaic panels.

[0003] In related technologies, photovoltaic brackets need to be equipped with two cables to connect and fix a row of photovoltaic panels, that is, two cables to a row, and a certain gap needs to be reserved between each row of photovoltaic panels. However, such photovoltaic brackets are relatively expensive. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0047] The photovoltaic bracket 10 according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0048] Reference Figures 1-6 As shown, the photovoltaic support 10 according to an embodiment of the present invention includes: a left crossbeam 1, a right crossbeam 2, multiple cables 3 and multiple connecting components 4. The left crossbeam 1 and the right crossbeam 2 are spaced apart and arranged opposite each other in a first direction. The multiple cables 3 are spaced apart in a second direction. Each cable 3 is connected between the left crossbeam 1 and the right crossbeam 2. Each cable 3 is fixed with at least one connecting component 4. The photovoltaic panel 20 is adapted to be connected to the cable 3 through the connecting component 4. Some of the connecting components 4 are configured to connect two adjacent photovoltaic panels 20 in the second direction.

[0049] Here, the first direction and the second direction are different directions, for example, referring to... Figures 1-6 As shown, the first direction is left and right, and the second direction is front and back.

[0050] The photovoltaic bracket 10 can be used in a photovoltaic system to support and fix multiple photovoltaic panels 20 of the photovoltaic system so as to generate electricity through the array of photovoltaic panels 20.

[0051] Reference Figures 1-3 As shown, both the left crossbeam 1 and the right crossbeam 2 can extend in the front-to-back direction. The left crossbeam 1 and the right crossbeam 2 are spaced apart and arranged opposite each other in the left-to-right direction. Both the left crossbeam 1 and the right crossbeam 2 have ear plates 11 with ear plate holes 111. One end of each cable 3 is suspended on the ear plate hole 111 of the ear plate 11 of the left crossbeam 1, and the other end is pulled by a winch or other power equipment and suspended on the ear plate hole 111 of the ear plate 11 of the right crossbeam 2. The cable 3 can be equipped with a tensioner 12. The cable 3 can be tensioned by screwing the threaded sleeve 121 of the tensioner 12 so that each cable 3 is connected between the left crossbeam 1 and the right crossbeam 2 in a tensioned state.

[0052] Reference Figures 3-5 As shown, the cable 3 can be a steel strand, with each cable 3 parallel to each other and extending in the left and right directions. The cable 3 can be arranged perpendicular to the left crossbeam 1 and the right crossbeam 2. Multiple photovoltaic panels 20 can be arranged in rows in the extension direction of the cable 3, forming a multi-row array structure in the interval direction of the cable 3. In other words, multiple photovoltaic panels 20 are arranged in rows in the left and right directions and form a multi-row structure in the front and back directions, so that multiple photovoltaic panels 20 form an array arrangement structure.

[0053] Reference Figure 6 As shown, each cable 3 is fixed with at least one connecting component 4. The photovoltaic panel 20 is adapted to be connected to the cable 3 through the connecting component 4. Some connecting components 4 are configured to connect two adjacent photovoltaic panels 20 in the second direction. That is, each cable 3 is fixed with at least one connecting component 4. In the front-back direction, at least one cable 3 is connected to the photovoltaic panels 20 on its front and back sides through the connecting component 4. It can be understood that by using the combination of cable 3 and connecting component 4, in the front-back direction, three cables 3 can be overlapped to fix two rows of photovoltaic panels 20. The connecting component 4 on the middle cable 3 can connect the photovoltaic panels 20 on both sides of it, that is, three cables overlap two rows. Compared with two cables overlap one row, the photovoltaic bracket 10 of this utility model embodiment can reduce the row spacing of two rows of photovoltaic panels 20 in the front-back direction, improve the installed capacity and land utilization rate, and also reduce the number of cables 3 used, thus reducing the cost of a single watt photovoltaic bracket 10.

[0054] It should be noted that the photovoltaic bracket 10 fixes the photovoltaic panel 20 through the connecting components 4 on multiple cables 3. The connection between the photovoltaic panel 20 and the cables 3 has high stability and reliability. The two adjacent photovoltaic panels 20 in each row do not need to be connected by connecting components within the row, which helps to reduce the manufacturing and assembly costs of the photovoltaic bracket 10.

[0055] Meanwhile, multiple photovoltaic panels 20 are arranged in an array and fixed on the photovoltaic bracket 10. After the photovoltaic bracket 10 and multiple photovoltaic panels 20 are connected, they form an integral structure. When the integral structure is subjected to external forces (such as wind), the multiple photovoltaic panels 20 arranged in an array can support each other and transmit force through the connecting components 4 and the cables 3, thereby reducing the risk of collision and damage between the photovoltaic panels 20 in the front and rear rows and enhancing the wind resistance performance of the photovoltaic bracket 10.

[0056] It is understandable that the photovoltaic support 10 fixes the photovoltaic panel 20 through the connecting components 4 on multiple cables 3. The photovoltaic support 10 is a flexible support, which can adjust the length of the cables 3 in the left and right directions and the number of cables 3 and connecting components 4 according to the number of photovoltaic panels 20 laid. It can also adjust the spacing of the cables 3 in the front and back directions and the length in the left and right directions according to the size of the photovoltaic panels 20 to be laid. The photovoltaic support 10 can be adapted to photovoltaic panels 20 of different sizes and quantities, and has good application prospects.

[0057] According to the photovoltaic bracket 10 of this utility model embodiment, the cable 3 is connected to the photovoltaic panels 20 on its front and rear sides through the connecting component 4, so that the three cables 3 can overlap and fix the two rows of photovoltaic panels 20, thereby reducing the row spacing of the two rows of photovoltaic panels 20 in the front and rear direction, improving the wind resistance performance and land utilization of the photovoltaic bracket 10, and also reducing the number of cables 3 used, thus reducing the cost of the photovoltaic bracket 10.

[0058] In some embodiments of this utility model, reference is made to Figure 5 and Figure 6 As shown, in the second direction, the spacing between any two adjacent photovoltaic panels 20 is less than or equal to 500 mm.

[0059] Specifically, in the second direction row, that is, the front-to-back direction, the distance between any two adjacent photovoltaic panels 20 is D1. D1 is also the row spacing between two adjacent rows of photovoltaic panels 20. D1 can be adjusted by designing different positions of the photovoltaic panels 20 and the connecting components 4, so that D1 satisfies the relationship: D1≤500mm, so as to reduce the row spacing, increase the number of photovoltaic panels 20 fixed by the photovoltaic bracket 10, and reduce the footprint of the photovoltaic bracket 10.

[0060] For example, D1 can be 0mm, 15mm, 50mm, 100mm, 200mm, 300mm, 400mm, 500mm, etc. When D1 is 0mm, any two adjacent photovoltaic panels 20 can abut against each other in the front-to-back direction, thus improving the mutual support and connection between the two adjacent photovoltaic panels 20. When 0mm < D1 ≤ 500mm, there is a certain gap between any two adjacent photovoltaic panels 20 in the front-to-back direction. This gap allows wind, rain, and dust to pass through, which helps improve the wind resistance and drainage performance of the photovoltaic support 10, and also facilitates the cleaning of dust on the photovoltaic panels 20. In addition, the gap can also be used to release the alternating stress generated during cooling, improving the reliability and service life of the photovoltaic panels 20.

[0061] In some embodiments of this utility model, reference is made to Figure 6 As shown, the connecting component 4 includes a first clamping plate 41 and a second clamping plate 42, the first clamping plate 41 and the second clamping plate 42 are connected and clamped to the corresponding cable 3, and the first clamping plate 41 and / or the second clamping plate 42 are adapted to be connected to the photovoltaic panel 20.

[0062] The first clamping plate 41 and the second clamping plate 42 can be connected by welding, bonding, fastener connection or other means. The first clamping plate 41 and the second clamping plate 42 are clamped on the corresponding cable 3. In the left and right direction, the cable 3 can be passed between the first clamping plate 41 and the second clamping plate 42. When the photovoltaic panel 20 is installed, the position of the first clamping plate 41 and the second clamping plate 42 clamping the cable 3 can be adjusted according to the size and position of the photovoltaic panel 20, so as to facilitate the flexible on-site assembly of the connecting component 4 and the photovoltaic panel 20.

[0063] Reference Figure 6 As shown, in some embodiments, the first clamping plate 41 and the second clamping plate 42 are both suitable for connection with the photovoltaic panel 20. The first clamping plate 41 and the second clamping plate 42 can be connected to the photovoltaic panel 20 by welding, bonding, fastener connection or other means. The connection between the connecting component 4 and the photovoltaic panel 20 has high reliability.

[0064] In other embodiments (not shown in the figures), one of the first clamping plate 41 and the second clamping plate 42 is adapted to be connected to the photovoltaic panel 20 to facilitate the assembly of the photovoltaic panel 20 with the connecting assembly 4.

[0065] In some embodiments of this utility model, reference is made to Figure 6As shown, the first clamping plate 41 includes a front connecting section 411, an arc-shaped section 412, and a rear connecting section 413. The arc-shaped section 412 is connected between the front connecting section 411 and the rear connecting section 413. Both the front connecting section 411 and the rear connecting section 413 are connected to the second clamping plate 42. The arc-shaped section 412 and the second clamping plate 42 together define a clamping hole 43. The cable 3 passes through the clamping hole 43, and the inner wall of the clamping hole 43 corresponding to the arc-shaped section 412 is in contact with the surface of the cable 3.

[0066] The front connecting section 411 and the rear connecting section 413 are both connected to the second clamping plate 42. The arc-shaped section 412 and the second clamping plate 42 together define the clamping hole 43. The cross-section of the cable 3 can be circular. The cable 3 passes through the clamping hole 43. In the vertical direction, the upper surface of the cable abuts against the second clamping plate, and the lower surface of the cable contacts the arc-shaped section 412. This increases the contact area between the cable 3 and the connecting component 4, ensuring a stable and reliable connection between the cable 3 and the connecting component 4. This makes it less likely for the connecting component 4 to move or rotate relative to the cable 4, thereby reducing the risk of the photovoltaic panel 20 shaking on the connecting component 4 and improving the stability of the photovoltaic panel 20.

[0067] In some embodiments of this utility model, the connecting component 4 further includes: a first fastener and a second fastener, the front connecting section 411 and the second clamping plate 42 are connected by the first fastener, and the first fastener is also adapted to be connected to the photovoltaic panel 20 on one side of the cable 3, the rear connecting section 413 and the second clamping plate 42 are connected by the second fastener, and the second fastener is also adapted to be connected to the photovoltaic panel 20 on the other side of the cable 3.

[0068] The front connecting section 411 may have a first mounting hole, the second clamping plate 42 may have a second mounting hole, and the frame of the photovoltaic panel 20 connected to the front connecting section 411 and the second clamping plate 42 may have a third mounting hole. The first fastener may be inserted through the first mounting hole, the second mounting hole and the third mounting hole to fix the front side of the connecting component 4 to a photovoltaic panel 20.

[0069] The rear connecting section 413 may have a fourth mounting hole, the second clamping plate 42 may have a fifth mounting hole, and the photovoltaic panel 20 connected to the rear connecting section 413 and the second clamping plate 42 may have a sixth mounting hole on its frame. The second fastener may be inserted through the third mounting hole, the fourth mounting hole and the fifth mounting hole to fix the rear side of the connecting component 4 to another photovoltaic panel 20.

[0070] In the above embodiment, the first fastener and the second fastener fix the first clamping plate 41 and the second clamping plate 42 to the front and rear sides of the clamping hole 43 to improve the reliability of the connection between the connecting component 4 and the cable 3. At the same time, the first fastener is also fixedly connected to the photovoltaic panel 20 on the front side of the connecting component 4, and the second fastener is also fixedly connected to the photovoltaic panel 20 on the rear side of the connecting component 4. That is to say, the first fastener connects the front connecting section 411, the second clamping plate 42 and the photovoltaic panel 20 on the front side of the connecting component 4, and the second fastener connects the rear connecting section 413, the second clamping plate 42 and the photovoltaic panel 20 on the rear side of the connecting component 4, so as to give full play to the fastening connection function of the first fastener and the second fastener, reduce the number of parts of the connecting component 4, and reduce the manufacturing and assembly cost of the connecting component 4.

[0071] In some embodiments of this utility model, reference is made to Figure 1 and Figures 3-5 As shown, the photovoltaic support 10 also includes a middle crossbeam 6, which is located between the left crossbeam 1 and the right crossbeam 2, and each cable 3 is connected to the middle crossbeam 6.

[0072] Specifically, in the left-right direction, the middle crossbeam 6 is located between the left crossbeam 1 and the right crossbeam 2. Each cable 3 is connected to the middle crossbeam 6. The middle crossbeam 6 can support the middle part of the cable 3 between the left crossbeam 1 and the right crossbeam 2 to reduce the sagging of the middle part of the cable 3. Multiple middle crossbeams 6 can be arranged at intervals in the left-right direction. The number of middle crossbeams 6 can be positively correlated with the length of the cable 3 in the left-right direction. That is, the longer the length of the cable 3 in the left-right direction, the more middle crossbeams 6 there are, so as to ensure the load-bearing capacity of the cable 3 and enable the cable 3 to stably and reliably fix the photovoltaic panel 20.

[0073] In some embodiments of this utility model, reference is made to Figure 3 , Figure 10 and Figure 11 As shown, the left crossbeam 1, the right crossbeam 2, at least one middle crossbeam 6 and at least two cables 3 together constitute a support unit 9. The photovoltaic support 10 includes multiple support units 9. In the second direction, the multiple support units 9 are arranged at intervals, and the distance between any two adjacent support units 9 is less than 1000mm.

[0074] Specifically, the support unit 9 may include: a left crossbeam 1, a right crossbeam 2, at least one middle crossbeam 6, and at least two cables 3. The left crossbeam 1 and right crossbeam 2 of the support unit 9 are arranged opposite each other in the left-right direction. The cables 3 are connected to the left crossbeam 1 and right crossbeam 2 respectively. The middle crossbeam 6 supports the cables 3 between the left crossbeam 1 and right crossbeam 2. The support unit 9 can fix at least one row of photovoltaic panels 20. It can be understood that the photovoltaic support 10 includes multiple modular support units 9. Different numbers of support units 9 can be selected according to the size of the site where the photovoltaic support 10 is arranged, so as to facilitate the construction and installation of the photovoltaic support 10 and make the photovoltaic support 10 adaptable to different sites.

[0075] In the second direction, i.e. the front-to-back direction, the distance between any two adjacent support units 9 is D2. D2 can be changed by adjusting the installation position of the support unit 9 so that D2 satisfies the relationship: D2≤1000mm. This is to avoid the distance between the support units 9 being too large, and to prevent the photovoltaic panel 20 from being overly overhanging in the support unit 9. This is beneficial to improving the reliability of the photovoltaic support 10 in supporting the photovoltaic panel 20.

[0076] For example, D2 can be 0mm, 100mm, 200mm, 500mm, 800mm, 1000mm, etc. When D2 is 0mm, any two adjacent support units 9 in the front-to-back direction can abut against each other, thus improving the mutual support and reliability of the connection between the two adjacent support units 9. When 0mm < D2 ≤ 1000mm, there is a certain gap between any two adjacent support units 9 in the front-to-back direction. This gap allows wind, rain, and dust to pass through, which is beneficial to improving the wind resistance and drainage performance of the photovoltaic support 10, and also facilitates the cleaning of dust on the photovoltaic panel 20. The gap can also be used to release the alternating stress generated during cooling, thereby improving the reliability and service life of the support unit 9.

[0077] In some embodiments of this utility model, two adjacent support units 9 are independent of each other or connected by photovoltaic panels 20.

[0078] Reference Figures 1-5 In the embodiment shown, each support unit 9 includes: a left crossbeam 1, a right crossbeam 2, two middle crossbeams 6 and five cables 3. Adjacent support units 9 are connected by photovoltaic panels 20, thereby connecting multiple support units 9 into one, which is beneficial to improving the stability and reliability of the overall structure of the photovoltaic support 10.

[0079] Reference Figures 7-11In the illustrated embodiment, each support unit 9 includes: a left crossbeam 1, a right crossbeam 2, four middle crossbeams 6, and five cables 3. Adjacent support units 9 are independent of each other, meaning that there is no rigid connection between adjacent support units 9. The photovoltaic panels 20 on adjacent support units 9 are also separated, meaning that each support unit 9 can independently fix its corresponding photovoltaic panel 20. Each support unit 9 can be installed at different heights on the ground to facilitate the construction and assembly of the photovoltaic support 10, making the photovoltaic support 10 adaptable to different installation sites. In addition, when some support units 9 are damaged, the impact of the damaged support units 9 on other undamaged support units 9 can be reduced, avoiding damage to the entire photovoltaic support 10 due to the collapse of some support units 9, thereby reducing the loss of the photovoltaic support 10 and the photovoltaic system in the event of natural disasters such as earthquakes.

[0080] In some embodiments of this utility model, reference is made to Figures 1-5 As shown, the multiple cables 3 are divided into multiple first cables 3a and at least one second cable 3b. In the second direction, the multiple first cables 3a are arranged at intervals, and there is a second cable 3b between any two adjacent first cables 3a. In the third direction, the height of the second cable 3b is greater than the height of the first cable 3a. The first direction, the second direction and the third direction are perpendicular to each other.

[0081] Reference Figures 1-6 As shown, the first direction is left and right, the second direction is front and back, and the third direction is up and down.

[0082] Understandably, the multiple cables 3 are divided into multiple first cables 3a and at least one second cable 3b. In the front-to-back direction, the multiple first cables 3a are arranged at intervals, and there is a second cable 3b between any two adjacent first cables 3a. That is, N first cables 3a correspond to (N-1) second cables 3b. In the vertical direction, the first cables 3a and the second cables 3b are at different heights. Each first cable 3a is at the same height between the left crossbeam 1 and the right crossbeam 2, and each second cable 3b is at the same height between the left crossbeam 1 and the right crossbeam 2. There is a height difference between the first cables 3a and the second cables 3b so that the photovoltaic panel 20 can form an angle when laid between the first cables 3a and the second cables 3b, making it less likely for rainwater and dust to adhere to the photovoltaic panel 20, thereby improving power generation efficiency.

[0083] Reference Figure 2 As shown, both the left crossbeam 1 and the right crossbeam 2 can be provided with ear plates 11 at different heights at their upper and lower ends. When the second cable 3b is higher than the first cable 3a, the second cable 3b can be connected to the ear plates 11 at the upper end of the left crossbeam 1 and the right crossbeam 2, and the first cable 3a can be connected to the ear plates 11 at the lower end of the left crossbeam 1 and the right crossbeam 2.

[0084] Meanwhile, due to the different heights of the first cable 3a and the second cable 3b, the two adjacent rows of photovoltaic panels 20 are arranged back-to-back symmetrically in the front-to-back direction. That is, the tilt angles of the two adjacent rows of photovoltaic panels 20 are opposite, and each row of photovoltaic panels 20 is closely arranged, which improves the wind shading effect of the front row of photovoltaic panels 20 on the rear row of photovoltaic panels 20. The wind shading effect of the photovoltaic panels 20 on the windward side on the leeward side of photovoltaic panels 20 is particularly obvious, which is equivalent to reducing the wind load borne by half of the photovoltaic panels 20, thereby significantly reducing the overall stress on the photovoltaic support 10 and improving the safety of the photovoltaic support 10.

[0085] Furthermore, since the photovoltaic panels 20 of adjacent rows are arranged back-to-back symmetrically in the front-to-back direction, the array-type photovoltaic panels 20 will not need to be restricted to a strict east-west orientation in order to increase power generation, which further improves the terrain adaptability of the photovoltaic support 20. The photovoltaic support 10 can be used in low-latitude regions to reduce the mutual shading effect of the photovoltaic panels 20 on sunlight.

[0086] Reference Figures 2-5 As shown, in the third direction, the height of the second cable 3b is greater than the height of the first cable 3a. Since there is a second cable 3b between any two adjacent first cables 3a, and the second cable 3b is higher than the first cable 3a, in the front-to-back direction, the front end of the photovoltaic panel 20 is connected to the lower first cable 3a and the rear end is connected to the higher second cable 3b, so that the photovoltaic panel 20 in the front row forms an inclined structure with a low front end and a high rear end. Similarly, the rear end of the photovoltaic panel 20 in the back row is connected to the lower first cable 3a and the front end is connected to the higher second cable 3b, so that the rear end of the photovoltaic panel 20 in the back row forms an inclined structure with a low front end and a high rear end. The photovoltaic panels 20 form an inclined structure with a high front end and a low rear end. In other words, when viewed from the left and right, the shape formed by multiple photovoltaic panels 20 is "∧∧∧∧" rather than "VVVV". The photovoltaic panels 20 in the front row and the photovoltaic panels 20 in the back row form an inclined top structure suitable for draining water and dust to the outside of the photovoltaic support 10, so as to facilitate the discharge of rainwater and dust. At the same time, when the photovoltaic support 10 encounters wind from the front and back, the upper surfaces of the photovoltaic panels 20 in the front row and the photovoltaic panels 20 in the back row are the windward surfaces, which can use the wind force to remove dust from the upper surfaces of the photovoltaic panels 20, thereby improving the power generation efficiency.

[0087] In other embodiments of this utility model, reference is made to Figures 7-11 As shown, the multiple cables 3 have three heights in the third direction. For the five cables 3 on the same support unit 9, four photovoltaic panels 20 can be fixed together. In the front-back direction, the height arrangement of the five cables 3 is to first rise and then fall, so that the four photovoltaic panels 20 fixed on them form a "∧" shape.

[0088] In some other embodiments of this utility model (not shown in the figures), each cable 3 has the same height in the third direction, that is, multiple photovoltaic panels 20 fixed on the photovoltaic bracket 10 can be located on the same horizontal plane.

[0089] It should be noted that, according to the photovoltaic bracket 10 of this utility model embodiment, the multiple photovoltaic panels 20 fixed on it can form a planar or zigzag wave shape. In low-latitude regions, there is no mutual shading or the shading area between photovoltaic panels 20 is small. Therefore, the cable 3 can be arranged in the east-west or north-south direction, and the arrangement of the photovoltaic bracket 10 is flexible and convenient.

[0090] In some embodiments of this utility model, reference is made to Figures 3-5 As shown, the middle crossbeam 6 includes a middle crossbeam body 61 and a middle crossbeam strut 62. The middle crossbeam body 61, the left crossbeam 1, and the right crossbeam 2 are arranged in parallel. The first cable 3a is connected to the middle crossbeam body 61, and the middle crossbeam strut 62 is connected to the middle crossbeam body 61. In the third direction, the height of the upper end of the middle crossbeam strut 62 is greater than the height of the middle crossbeam body 61. The second cable 3b is connected to the upper end of the middle crossbeam strut 62.

[0091] The first cable 3a is connected to the middle crossbeam body 61 by U-bolts 8, and the second cable 3b is connected to the upper end of the middle crossbeam support rod 62 by U-bolts 8. Multiple first cables 3a can be supported and fixed on the middle crossbeam body 61, and multiple middle crossbeam support rods 62 can be provided on the middle crossbeam body 61 to support and fix the corresponding second cable 3b through each middle crossbeam support rod 62.

[0092] In the above embodiment, the height of the upper end of the middle crossbeam support 62 is greater than the height of the middle crossbeam body 61. The first cable 3a is connected to the middle crossbeam body 61, and the second cable 3b is connected to the upper end of the middle crossbeam support 62, which helps to maintain the height difference between the first cable 3a and the second cable 3b.

[0093] In some embodiments of this utility model, reference is made to Figure 5 As shown, the middle crossbeam strut 62 includes a straight strut 621 and a diagonal strut 622. The straight strut 621 extends along a third direction. In the third direction, the upper end of the straight strut 621 is connected to the second cable 3b, and the lower end of the straight strut 621 is connected to the middle crossbeam body 61. The diagonal strut 622 is inclinedly connected to the straight strut 621 and the middle crossbeam body 61.

[0094] Specifically, the lower ends of the straight strut 621 and the diagonal strut 622 can be welded to the middle crossbeam body 61, and the upper end of the diagonal strut 622 can be welded to the upper end of the straight strut 621. The diagonal strut 622 is inclined relative to the straight strut 621. The straight strut 621, the middle crossbeam body 61, and the diagonal strut 622 can form a triangular frame structure to improve the structural stability of the middle crossbeam strut 62, reduce the risk of the second cable 3b swaying, and thus help improve the overall stability of the photovoltaic bracket 10.

[0095] In some embodiments of this utility model, reference is made to Figure 4 As shown, in the second direction, there are multiple middle crossbeams 6, and the difference in the number of middle crossbeam struts 62 between any two adjacent middle crossbeams 6 is an odd number.

[0096] In the left-right direction, there are multiple middle crossbeams 6, and the difference in the number of middle crossbeam struts 62 between any two adjacent middle crossbeams 6 is an odd number. That is, in two adjacent middle crossbeams 6, the difference in the number of middle crossbeam struts 62 is only odd when one middle crossbeam 6 has an odd number of middle crossbeam struts 62 and the other middle crossbeam 6 has an even number of middle crossbeam struts 62. At this time, the two adjacent middle crossbeams 6 can be connected by an inclined photovoltaic panel 20, so that the two adjacent middle crossbeams 6 can form a stable and reliable connection, thereby improving the overall stability of the photovoltaic support 10.

[0097] For example, refer to Figure 4 As shown, in two adjacent crossbeams 6, one crossbeam 6 has two crossbeam struts 62, and the other crossbeam 6 has three crossbeam struts 62. The number of crossbeam struts 62 corresponds one-to-one with the number of second cables 3b. That is, the crossbeam 6 with two crossbeam struts 62 can support and fix two second cables 3b and three first cables 3a. The number of photovoltaic panels 20 on this crossbeam 6 is four and they form an "M" shape. The crossbeam 6 with three crossbeam struts 62 can support and fix three second cables 3b and two first cables 3a. The number of photovoltaic panels 20 on this crossbeam 6 is four and they form a "W" shape. These two adjacent crossbeams 6 can be connected by an inclined photovoltaic panel 20 so that multiple photovoltaic panels 20 form a continuous zigzag shape, thereby strengthening the connection strength between the two adjacent crossbeams 6.

[0098] In some embodiments of this utility model, the photovoltaic bracket 10 further includes a support component 7, wherein the left crossbeam 1, the right crossbeam 2, and the middle crossbeam 6 are all fixed to the ground by the support component 7.

[0099] Reference Figure 1 and Figure 4As shown, the support assembly 7 may include: end piles 71, end anchor piles 72, end columns 73, end vertical tie rods 74, middle piles 75, and middle columns 76. The end piles 71, end anchor piles 72, and middle piles 75 can be inserted and fixed to the ground. The left crossbeam 1 is connected to the corresponding end anchor pile 72 on the left side via the corresponding end vertical tie rod 74. The left crossbeam 1 is also connected to the corresponding end pile 71 on the left side via the corresponding end column 73. The right crossbeam 2 is connected to the corresponding end anchor pile 72 on the right side via the corresponding end vertical tie rod 74. The right crossbeam 2 is also connected to the corresponding end pile 71 on the right side via the corresponding end column 73. The middle crossbeam 6 is connected to the corresponding middle pile 75 via the corresponding middle column 76. The support assembly 7 provides stable and reliable support for the left crossbeam 1, right crossbeam 2, and middle crossbeam 6 to ensure the stability of the photovoltaic bracket 10.

[0100] It should be noted that the piles, columns, tie rods and other structures that make up the support component 7 are not limited to these. The support component 7 may include support components such as wind ropes. The types and quantities of components that make up the support component 7 can be adjusted according to the actual situation of the project and the different application scenarios. The components that make up the support component 7 can be flexibly selected and used to ensure the stability of the support component 7 structure and meet the usage requirements.

[0101] In some embodiments of this utility model, the assembly process of the photovoltaic bracket 10 and the photovoltaic panel 20 is as follows:

[0102] Step S1: Install the end pile 71, end anchor pile 72, middle pile 75, end column 73, middle column 76, left crossbeam 1, right crossbeam 2, and middle crossbeam 6 in the preset positions in sequence.

[0103] Step S2: Suspend cable 3 between left crossbeam 1 and right crossbeam 2, and tension cable 3 by turning the threaded sleeve 121 of tensioner 12.

[0104] Step S3: Install the end vertical tie rod 74.

[0105] In step S4, the photovoltaic panel 20 is laid along the extension direction (left and right direction) of the cable 3, and the photovoltaic panel 20 is connected to the cable 3 through the connecting component 4.

[0106] The photovoltaic panel 20 can be a rectangular panel, and it can be laid horizontally or vertically. When laid horizontally, the long side of the photovoltaic panel 20 is parallel to the extension direction of the cable 3, and when laid vertically, the long side of the photovoltaic panel 20 is perpendicular to the extension direction of the cable 3.

[0107] It should be noted that the spacing between two adjacent photovoltaic panels 20 in the front-back and left-right directions can be less than 500mm to increase the installed capacity and improve land utilization. In addition, wind-resistant ropes can be installed in necessary locations to further improve the wind resistance stability and safety of the photovoltaic support 10.

[0108] According to the embodiment of the present utility model, the photovoltaic bracket 10 utilizes the high strength of the cable 3, the designability of the cable 3 position, and the convenience of installing the photovoltaic panel 20 on the cable 3. The photovoltaic panels 20 in two adjacent rows are arranged back-to-back symmetrically, that is, the photovoltaic panels 20 have opposite tilt angles (when the tilt angle is 0 degrees, they are all laid flat). The photovoltaic panels 20 on two adjacent middle crossbeams 6 form an M+W type structure. The photovoltaic panels 20 form a continuous array in the front and back direction. The photovoltaic bracket 10 improves the original two cables for one row to three cables for two rows, which can reduce the number of cables 3 used, reduce the manufacturing cost of the photovoltaic bracket 10 per watt, and improve the installed capacity and land utilization rate. Meanwhile, adjacent photovoltaic panels 20 can be arranged without spacing or with a small spacing (less than 500mm). The photovoltaic panels 20 form a continuous whole in the left-right and front-back directions, without restricting each row of photovoltaic panels 20 to a strict east-west orientation. This further improves the terrain adaptability of the photovoltaic support 10, and also helps to improve the wind resistance and land utilization of the photovoltaic support 10, ensuring the structural stability and safety of the photovoltaic support 10.

[0109] A photovoltaic system according to another embodiment of the present invention includes a plurality of photovoltaic panels 20 and the photovoltaic support 10 described above.

[0110] According to the photovoltaic system of this utility model embodiment, the cable 3 of the photovoltaic support 10 is connected to the photovoltaic panels 20 on its front and rear sides through the connecting component 4. The three cables 3 can be overlapped to fix two rows of photovoltaic panels 20, thereby reducing the row spacing of the two rows of photovoltaic panels 20 in the front and rear direction, improving the wind resistance performance and land utilization of the photovoltaic support 10, and also reducing the number of cables 3 used, thus reducing the cost of the photovoltaic system.
