Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and more specifically, to a flexible photovoltaic tracking bracket and a photovoltaic system. Background Technology

[0002] Traditional flexible photovoltaic (PV) systems typically employ a mechanism that adjusts the angle of the PV panels according to the sun's movement to maximize their solar surface area and improve power generation efficiency. To enhance wind resistance, wind-resistant supports are usually installed. To prevent wind suction and uplift, these supports are typically connected to ground anchors via vertical cables to limit vertical displacement caused by wind. Furthermore, to accommodate rotation, curved members are installed at the bottom of the wind-resistant supports, connected to the vertical cables via a sliding mechanism. However, under strong wind suction, this sliding mechanism cannot operate smoothly, resulting in poor stability.

[0003] In addition, ground anchors are usually set at the mid-span position, which prevents the full utilization of the advantages of flexible supports in terms of large span and large space.

[0004] Therefore, how to improve the stability of flexible photovoltaic supports while ensuring the effective light-receiving area of ​​photovoltaic panels has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0054] The core of this application is to provide a flexible photovoltaic tracking bracket to improve the stability of the flexible photovoltaic tracking bracket while ensuring the effective light-receiving area of ​​the photovoltaic panel.

[0055] Another core aspect of this application is to provide a photovoltaic system with the aforementioned flexible photovoltaic tracking bracket.

[0056] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0057] In order to allow the photovoltaic panels to receive more sunlight, traditional flexible photovoltaic systems typically use a method that drives the photovoltaic panels to adjust their angle according to the sun's movement, so that the photovoltaic panels have a larger light-receiving surface and improve power generation efficiency.

[0058] To improve wind resistance, wind-resistant supports are typically installed. To prevent these supports from being sucked in or lifted by wind, they are usually connected to ground anchors via vertical cables to limit vertical displacement caused by wind suction and lifting. Additionally, to accommodate rotation, curved members are installed at the bottom of the wind-resistant supports, and these curved members are connected to the vertical cables via a sliding mechanism.

[0059] Traditionally, the sliding mechanism cannot slide smoothly under strong wind suction, resulting in poor stability. In addition, the ground anchor is usually set at the mid-span, which prevents the full utilization of the advantages of flexible supports for large spans and large spaces.

[0060] Therefore, such as Figure 1 As shown in the figure, this application discloses a flexible photovoltaic tracking bracket, including a main cable assembly 100, a support structure 200, a drive assembly, and a wind-resistant assembly 500. The rotation of the crossbeam assembly 300 drives the photovoltaic panel 700 on the main cable 101 to rotate, thereby adjusting the angle of the photovoltaic panel 700 to ensure a larger effective light-receiving area. Furthermore, the wind-resistant frame 501 is connected to both the main cable 101 and the stabilizing cable 401 to form an integrated spatial structure, improving the overall stability of the flexible photovoltaic tracking bracket.

[0061] The following will combine Figures 1 to 18 The flexible photovoltaic tracking bracket disclosed in the embodiments of this application will be explained and described in detail.

[0062] Among them, such as Figure 1 and Figure 3 As shown, the main cable assembly 100 may include at least two parallel main cables 101 to lay the photovoltaic panel 700 on the main cables 101 and to rigidly connect it to the main cables 101. The main cables 101 may be, but are not limited to, two parallel main cables, or four or more, to ensure the stability of the connection of the photovoltaic panel 700.

[0063] like Figures 1 to 3 As shown, the support structure 200 may include at least two, with the two support structures 200 located at opposite ends of the main cable assembly 100 to anchor the main cable assembly 100, thereby bearing the tensile force from the main cable assembly and transferring it to the ground foundation. Of course, the support structure 200 may be, but is not limited to, two, three, four, or more, to form a multi-span flexible photovoltaic tracking bracket. The specific number of support structures 200 can be determined according to the span of the flexible photovoltaic tracking bracket.

[0064] At the same time, such as Figure 1As shown, the drive assembly includes a crossbeam assembly 300 and a drive member 600. The crossbeam assembly 300 is rotatably connected to the support structure 200. The two ends of the main cable assembly 100 are respectively fixed to the crossbeam assembly 300, and the drive member 600 is connected to the crossbeam assembly 300 for transmission. The drive member 600 drives the crossbeam assembly 300 to rotate, thereby driving the photovoltaic panel 700 on the main cable 101 to rotate. This allows the angle of the photovoltaic panel 700 to be adjusted to ensure a larger effective light-receiving area for the photovoltaic panel 700.

[0065] To improve the wind resistance and stability of flexible photovoltaic tracking brackets, such as Figures 1 to 3 As shown, a wind-resistant component 500 is installed on the flexible photovoltaic tracking bracket. The wind-resistant component 500 may include a stabilizing cable assembly 400 and a wind-resistant frame 501. The stabilizing cable assembly 400 may include at least one stabilizing cable 401, which is located below the main cable 101, and both ends of the stabilizing cable 401 are fixed to the crossbeam assembly 300. The wind-resistant frame 501 is connected to both the stabilizing cable 401 and the main cable 101 to form an integrated spatial structure, thereby improving the overall stability of the flexible photovoltaic tracking bracket. For ease of understanding, the upper and lower sides of the wind-resistant frame 501 are defined as the first side and the second side, respectively. The first side of the wind-resistant frame 501 is rigidly connected to each main cable 101, and the second side of the wind-resistant frame 501 is rigidly connected to each stabilizing cable 401, thereby forming an integral spatial structure. This improves the overall stability of the flexible photovoltaic tracking bracket and can effectively resist the torsion and collision of the photovoltaic panel 700 by wind load, snow load and gravity load, reducing the risk of damage to the photovoltaic panel 700 due to wind force. At the same time, it can reduce the risk of the photovoltaic panel 700 developing hidden cracks and overturning.

[0066] The stabilizing cable 401 can be one, but not limited to one; two, three, four, or more can also be used to improve the overall stability of the flexible photovoltaic tracking bracket. Preferably, two stabilizing cables 401 can be used, and the two stabilizing cables 401 are respectively located below the two main cables 101, so that the first side of the wind-resistant frame 501 can be rigidly connected to the two main cables 101, and the second side of the wind-resistant frame 501 can be rigidly connected to the two stabilizing cables 401, thereby forming a four-cage spatial structure, which can improve the overall stability of the flexible photovoltaic tracking bracket.

[0067] To prevent the wind-resistant frame 501 from vertical displacement due to wind suction and wind lifting, such as Figures 1 to 3As shown, the wind-resistant component 500 may further include wind-resistant cables 502 and vertical tension cables 503. The two ends of the wind-resistant cables 502 are connected to the support structure 200, and the wind-resistant cables 502 are connected to the wind-resistant frame 501 via the vertical tension cables 503. This causes the middle of the wind-resistant cables 502 to arch upwards. While limiting the vertical displacement of the wind-resistant frame 501 due to wind suction and lifting, this frees up space below the photovoltaic panels 700 of the flexible photovoltaic tracking bracket, improving the space utilization rate below the photovoltaic panels 700 and increasing the span of the flexible photovoltaic tracking bracket. Furthermore, under downward loads such as gravity, snow, and wind pressure, the vertical tension cables 503 and the arched wind-resistant cables 502 exhibit a compression tendency, preventing the generation of internal forces in the photovoltaic system and not affecting the rotation of the wind-resistant frame 501.

[0068] It should be noted that the two ends of the wind-resistant cable 502 can be connected to the ground or to the support structures 200 at both ends of the main cable assembly 100. Preferably, the two ends of the wind-resistant cable 502 are connected to the support structures 200 to improve the convenience of construction. The wind-resistant cable 502 can be connected to the support structures 200 through ear plates or clamps.

[0069] As can be seen from the above embodiments, the rotation of the crossbeam assembly 300 drives the photovoltaic panel 700 on the main cable 101 to rotate, thereby adjusting the angle of the photovoltaic panel 700 to ensure a larger effective light-receiving area. In addition, the four-cable spatial cage structure improves the overall stability of the flexible photovoltaic tracking bracket. At the same time, the wind-resistant frame 501 is connected to the wind-resistant cable 502 through the vertical cable 503, so that the middle part of the wind-resistant cable 502 arches upward. While limiting the vertical displacement of the wind-resistant frame 501 caused by wind suction and wind lifting, it can improve the space utilization rate under the photovoltaic panel 700 of the flexible photovoltaic tracking bracket and increase the span of the flexible photovoltaic tracking bracket.

[0070] In some embodiments, such as Figure 1 As shown, the wind-resistant frame 501 may include at least one planar wind-resistant frame 5011. Wherein, as... Figure 4 and Figure 9As shown, the planar wind-resistant frame 5011 may include an upper chord 506, a lower chord 507, and a first connecting rod 508. The upper chord 506 and the lower chord 507 are arranged parallel to each other, with the lower chord 507 located below the upper chord 506. Simultaneously, the two ends of the upper chord 506 can be connected to the two ends of the lower chord 507 via the first connecting rod 508, forming a planar truss system. Two main cables 101 can be connected to the two ends of the upper chord 506, and a stabilizing cable 401 can be connected to the lower chord 507. When there are two stabilizing cables 401, they can be connected to the two ends of the lower chord 507 to form a four-cable spatial cage structure, thereby improving the overall stability of the flexible photovoltaic tracking bracket. It should be noted that when there is only one stabilizing cable 401, it can be connected at the middle position of the lower chord 507 to form a three-cable spatial structure. Of course, three, four or more stabilizing cables 401 can also be used, and each stabilizing cable 401 can be connected to the lower chord 507 at intervals, which will not be elaborated here.

[0071] In addition, such as Figure 4 , Figure 6 and Figure 9 As shown, the vertical cable 503 can be connected to the rotation center of the wind-resistant frame 501. When upward loads such as wind suction or wind lifting are applied, the upper node of the vertical cable 503 will not shift when the wind-resistant frame 501 rotates with the main cable 101. This allows the vertical cable 503 to only provide vertical restraint to the wind-resistant frame 501, without generating additional torque due to the rotation of the wind-resistant frame 501. Specifically, the vertical cable 503 can be connected to the rotation center at the midpoint of the upper chord 506. One end of the vertical cable 503 can be connected to the rotation center of the upper chord 5061 via a U-shaped shackle, while the other end of the vertical cable 503 can be connected to the wind-resistant cable 502 via a connector 510.

[0072] In some embodiments, such as Figures 5 to 8As shown, to improve the overall stability of the planar wind-resistant frame 5011, at least one second connecting rod 509 is provided between the upper chord 506 and the lower chord 507 of the planar wind-resistant frame 5011, so that the first connecting rod 508, the adjacent second connecting rod 509, and the upper chord 506 or the lower chord 507 form a triangular structure, thereby improving the overall stability of the planar wind-resistant frame 5011. The second connecting rod 509 can be one, two, or more. For ease of understanding, the two ends of the upper chord 506 are defined as the first end and the second end, respectively, and the two ends of the lower chord 507 are defined as the first end and the second end, respectively. The first end of the upper chord 506 is on the same side as the first end of the lower chord 507, and the second end of the upper chord 506 is on the same side as the second end of the lower chord 507. Furthermore, the first end of the upper chord 506 and the first end of the lower chord 507 can be connected by the first connecting rod 508, and the second end of the upper chord 506 and the second end of the lower chord 507 can also be connected by the first connecting rod 508. Simultaneously, when only one second connecting rod 509 is used, the second connecting rod 509 can be connected to different sides of the upper chord 506 and the lower chord 507. That is, one end of the second connecting rod 509 is connected to the first end of the upper chord 506, and the other end is connected to the second end of the lower chord 507; or, one end of the second connecting rod 509 is connected to the second end of the upper chord 506, and the other end is connected to the first end of the lower chord 507. This creates a triangular structure between the first connecting rod 508 and the adjacent second connecting rod 509, and between the upper chord 506 or the lower chord 507, thereby improving the overall stability of the planar wind-resistant frame 5011.

[0073] Preferably, such as Figure 6 As shown, two second connecting rods 509 can be used, and one end of each second connecting rod 509 is connected to the first end and the second end of the upper chord 506, respectively. Meanwhile, the other ends of the two second connecting rods 509 can intersect at the midpoint of the lower chord 507, so that the first connecting rod 508 and the adjacent second connecting rod 509 and the upper chord 506 or the lower chord 507 form a triangular structure, thereby improving the overall stability of the planar wind-resistant frame 5011.

[0074] In some embodiments, such as Figure 1As shown, in order to improve the overall stability of the wind-resistant frame 501, the wind-resistant frame 501 may include two planar wind-resistant frames 5011. The two planar wind-resistant frames 5011 may be arranged parallel to each other along the extension direction of the main cable 101, or they may be arranged at a certain angle along the extension direction of the main cable 101. At the same time, the two planar wind-resistant frames 5011 may be connected by a third link, so that the two planar wind-resistant frames 5011 are connected to form an integral spatial truss structure. The two ends of the upper chord 506 and the two ends of the lower chord 507 of the two planar wind-resistant frames 5011 may be connected by a third link, and the third links may be arranged parallel or cross each other. Alternatively, the upper chord 506 of the two planar wind-resistant frames 5011 may be connected by a third link, and the lower chord 507 of the two planar wind-resistant frames 5011 may be connected by a third link. The third links connecting the upper chord 506 and the third links connecting the lower chord 507 may be arranged cross or parallel.

[0075] Preferably, such as Figures 9 to 13 As shown, two planar wind-resistant frames 5011 are set at a certain angle along the extension direction of the main cable 101, and the two planar wind-resistant frames 5011 can share a lower chord 507. That is, the lower chord 507 can be located directly below the central axis of the two planes where the upper chord 506 of the two planar wind-resistant frames 5011 is located. One end of the first connecting rod 508 of the two planar wind-resistant frames 5011 is connected to the end of the upper chord 506 of the two planar wind-resistant frames 5011, and the other end of the first connecting rod 508 of the two planar wind-resistant frames 5011 intersects the end of the lower chord 507 to form a V-shaped structure. This makes the wind-resistant frame 501 an inverted triangular cone-shaped spatial truss structure, thereby improving the overall stability of the wind-resistant frame 501 while reducing the number of members and saving costs.

[0076] More preferably, such as Figures 4 to 8 As shown, when each planar wind-resistant frame 5011 has two second connecting rods 509, one end of each second connecting rod 509 can be connected to the first and second ends of the upper chord 506, respectively, and the other ends of the two second connecting rods 509 can intersect at the midpoint of the lower chord 507, so that the second connecting rods 509 of the two planar wind-resistant frames 5011 are radially distributed, thereby further improving the overall stability of the wind-resistant frame 501. It should be noted that the number of second connecting rods 509 in each planar wind-resistant frame 5011 can also be one, three or more, or the two planar wind-resistant frames 5011 can use different numbers of second connecting rods 509.

[0077] Of course, in the above embodiments, the two planar wind-resistant frames 5011 can also share a single upper chord 506, so that the wind-resistant frame 501 is a regular triangular pyramidal space truss structure, which will not be elaborated here.

[0078] It should be noted that the wind-resistant frame 501 may also include three, four or more planar wind-resistant frames 5011, and each planar wind-resistant frame 5011 may be connected by a third link to form an integral spatial truss structure. Of course, each planar wind-resistant frame 5011 may also share a lower chord 507 or an upper chord 506.

[0079] In order to connect the wind-resistant frame 501, the main cable 101 and the stabilizing cable 401 to form an integral spatial structure, one or more wind-resistant frames 501 may be used.

[0080] In some embodiments, one wind-resistant frame 501 may be used, and the wind-resistant frame 501 may be located at the middle position between two adjacent support structures 200, so that the lower chord 507 of the wind-resistant frame 501 arches the middle position of the stabilizing cable 401 downward, so that the wind-resistant frame 501, the main cable 101 and the stabilizing cable 401 are connected to form an integral spatial structure, thereby improving the overall stability of the flexible photovoltaic tracking bracket.

[0081] In some embodiments, such as Figures 1 to 3 As shown, multiple wind-resistant frames 501 can be installed between two adjacent support structures 200 to improve the wind resistance of the flexible photovoltaic tracking bracket. Simultaneously, each wind-resistant frame 501 can be spaced out between two adjacent support structures 200. For ease of understanding, the wind-resistant frame 501 located closer to the support structure 200 is defined as the first wind-resistant frame 504, and the wind-resistant frame 501 located in the middle of the two support structures 200 is defined as the second wind-resistant frame 505. The vertical distance between the upper chord 506 and lower chord 507 of the second wind-resistant frame 505 is greater than the vertical distance between the upper chord 506 and lower chord 507 of the first wind-resistant frame 504. This allows the lower chord 507 of the second wind-resistant frame 505 to arch the middle position of the stabilizing cable 401 downwards, thereby connecting the wind-resistant frame 501, the main cable 101, and the stabilizing cable 401 to form an integrated spatial structure, improving the overall stability of the flexible photovoltaic tracking bracket. It should be noted that in the above embodiments, the number of wind-resistant frames 501 can be two, three, four or more.

[0082] In some embodiments, such as Figure 4 and Figure 9As shown, the upper chord 506 includes a support portion 5061 and connecting portions 5062 disposed at both ends of the support portion 5061. A first connecting rod 508 and a second connecting rod 509 can be connected to the support portion 5061, and the connecting portions 5062 and the support portion 5061 form an angle greater than 90°, so that the connecting portions 5062 of the upper chord 506 and the main cable 101 can be fixedly connected via connectors 510. Simultaneously, the lower chord 507 and the stabilizing cable 401 can be fixedly connected via connectors 510, so that the wind-resistant frame 501 rotates synchronously with the main cable 101 and the stabilizing cable 401. The connecting portions 5062 and the support portion 5061 can be separate structures, formed by welding to form the upper chord 506. Alternatively, the connecting portions 5062 and the support portion 5061 can be an integral structure, formed by bending; this is not limited here.

[0083] In some embodiments, such as Figure 18 As shown, the connector 510 may include a base 5101 and a U-shaped buckle 5102 that mates with the base 5101, and a through-hole is formed between the U-shaped buckle 5102 and the base 5101. When connecting the upper chord 506 and the main cable 101, the main cable 101 is passed through the U-shaped buckle 5102, and both ends of the U-shaped buckle 5102 pass through the two through holes opened on the connecting part 5062 of the upper chord 506 and the mounting hole of the base 5101 in sequence. After the washers 5103 are fitted on both ends of the U-shaped buckle 5102, nuts 5104 are threaded into both ends of the U-shaped buckle 5102 until the upper chord 506 and the main cable 101 are locked. Similarly, when connecting the lower chord 507 and the stabilizing cable 401, the stabilizing cable 401 is passed through the U-shaped buckle 5102, and the two ends of the U-shaped buckle 5102 pass through the two through holes opened on the lower chord 507 and the mounting holes of the base 5101 in sequence. After the washers 5103 are put on both ends of the U-shaped buckle 5102, the nuts 5104 are threadedly engaged with the two ends of the U-shaped buckle 5102 until the lower chord 507 and the stabilizing cable 401 are locked.

[0084] In some embodiments, such as Figure 1 and Figure 2As shown, the support structure 200 may include an end support structure 201 located at one end and a middle support structure 202 located between the two end support structures 201. The crossbeam assembly 300 includes an end crossbeam 301 and a middle crossbeam 302, wherein the end crossbeam 301 is rotatably mounted on the end support structure 201, and the middle crossbeam 302 is rotatably mounted on the middle support structure 202. The driving member 600 may be provided on either the end support structure 201 or the middle support structure 202, or the driving member 600 may be provided on both the end support structure 201 and the middle support structure 202. It should be noted that when the span of the flexible photovoltaic tracking bracket is small, only the end support structure 201 needs to be provided, and the middle support structure 202 is not required.

[0085] In the above embodiments, such as Figure 14 and Figure 16 As shown, the driving component 600 may include a drive motor 601 and a rotary reducer 602. The drive motor 601 provides power to the rotary reducer 602, which is connected to the crossbeam assembly 300 to drive the crossbeam assembly 300 to rotate. This, in turn, drives the main cable 101 and the stabilizing cable 401 connected to the crossbeam assembly 300 to rotate, thereby adjusting the angle of the photovoltaic panel 700, ensuring a larger light-receiving area for the photovoltaic panel 700, and improving power generation efficiency. The rotary reducer 602 may be a worm gear rotary reducer.

[0086] In some embodiments, such as Figure 14 As shown, the end support structure 201 may include a first support rod 2011 and two intersecting second support rods 2012. The first ends of the first support rod 2011 and the second support rods 2012 are both connected to the ground foundation, and the second ends of the first support rod 2011 and the second support rods 2012 are connected via a first mounting base 2013 to form a triangular frame structure. Simultaneously, a driving member 600 can be mounted on the first mounting base 2013 to drive the end beam 301 to rotate relative to the first mounting base 2013. Specifically, as... Figure 15 As shown, the first mounting base 2013 may include a first mounting part 2014, a second mounting part 2015, and a connecting lug 2016. The second end of the first support rod 2011 is detachably connected to the first mounting part 2014, such as via a flange connection or bolt connection. Simultaneously, the second ends of the two second support rods 2012 are respectively connected to the two connecting lugs 2016 of the first mounting base 2013. The rotary reducer 602 of the drive component 600 can be connected to the second mounting part 2015 via a flange connection to drive the end beam 301 to rotate relative to the first mounting base 2013.

[0087] In some embodiments, such as Figure 16As shown, the central support structure 202 may include a column 2021, with one end of the column 2021 connected to the ground foundation and a second mounting base 2022 provided at the second end of the column 2021. Simultaneously, a driving component 600 can be mounted on the second mounting base 2022 to drive the central crossbeam 302 to rotate synchronously with the end crossbeams 301 relative to the second mounting base 2022. Specifically, as... Figure 17 As shown, the second mounting base 2022 has an overall L-shaped structure. The rotary reducer 602 can be mounted on the vertical surface of the second mounting base 2022. Simultaneously, the horizontal surface of the second mounting base 2022 can be connected to the second end of the column 2021 using bolts or other fasteners. To avoid affecting the rotation of the central crossbeam 302, the position where the central crossbeam 302 mates with the second mounting base 2022 is arranged in an upward convex shape, such as... Figure 16 As shown. Meanwhile, to ensure the structural strength of the second mounting base 2022, a reinforcing plate 2023 may be provided on the second mounting base 2022.

[0088] In some embodiments, such as Figure 14 and Figure 16 As shown, one end of the main cable 101 can pass through the end crossbeam 301 and be fixed by a cable anchor, wherein the cable anchor abuts against the end crossbeam 301 to tighten the main cable 101. The other end of the main cable 101 can be fixed to the upper surface of the middle crossbeam 302 by a connector 510. Similarly, one end of the stabilizing cable 401 can pass through the end crossbeam 301 and be fixed by a cable anchor to prevent the stabilizing cable 401 from coming off the end crossbeam 301. The other end of the stabilizing cable 401 can be fixed to the upper surface of the middle crossbeam 302 by a connector 510.

[0089] This application also discloses a photovoltaic system, including a photovoltaic panel 700 and a flexible photovoltaic tracking bracket as disclosed in the above embodiments. Therefore, this flexible photovoltaic tracking bracket possesses all the technical effects of the aforementioned flexible photovoltaic tracking brackets, which will not be repeated here. Among them, as... Figure 1 As shown, multiple photovoltaic panels 700 can be used, each laid on the main cable 101 and rigidly connected to it. The angle of the photovoltaic panel 700 can be adjusted by rotating the main cable 101, ensuring a larger light-receiving area and improving power generation efficiency. It should be noted that... Figure 1 The installation of photovoltaic panels 700 shown is only an example and does not represent the situation after all panels have been installed, or the installation intervals, etc.
