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) mounting systems typically operate at a fixed angle, making it impossible to track the angle of sunlight and thus limiting the overall power generation efficiency of the PV system. Furthermore, because flexible PV mounting systems support the PV modules via flexible cables, their overall structural stability is relatively poor. In windy weather, these systems are prone to significant vibrations, which can cause microcracks or damage to the PV modules, or even destroy the entire system. This increases maintenance costs and negatively impacts the power generation efficiency of the PV power plant.

[0003] Therefore, how to improve the stability of flexible photovoltaic supports while adjusting their angle has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0035] The core of this application is to provide a flexible photovoltaic tracking bracket that improves the stability of the flexible photovoltaic bracket while allowing for angle adjustment.

[0036] Another core aspect of this application is to provide a photovoltaic system with the aforementioned flexible photovoltaic tracking bracket.

[0037] 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.

[0038] Photovoltaic (PV) mounting systems can be divided into rigid PV systems and flexible PV systems. Rigid PV systems use rigid purlins as supports for the PV modules, while flexible PV systems use flexible cables. Compared to rigid PV systems, flexible PV systems offer advantages such as higher headroom, larger spans, and greater terrain adaptability, making them suitable for locations like ponds, lakes, and gullies.

[0039] Traditional flexible photovoltaic (PV) mounting systems typically operate at a fixed angle, making it impossible to track the angle of sunlight and thus limiting the overall power generation efficiency of the PV system. Furthermore, because flexible PV mounting systems support the PV modules via flexible cables, their overall structural stability is relatively poor. In windy weather, these systems are prone to significant vibrations, which can cause microcracks or damage to the PV modules, or even destroy the entire system. This increases maintenance costs and negatively impacts the power generation efficiency of the PV power plant.

[0040] 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 bracket assembly 200, a drive assembly 300, and a wind-resistant assembly 400. The drive assembly 300 can adjust the angle of the flexible photovoltaic bracket to ensure a larger effective light-receiving area of ​​the photovoltaic panel and improve power generation efficiency. At the same time, by adding a wind-resistant bracket 401 and a damper 402, the flexible photovoltaic tracking bracket can have the ability to resist wind and reduce vibration, thereby improving the stability of the flexible photovoltaic tracking bracket.

[0041] The following will combine Figures 1 to 5 The flexible photovoltaic tracking bracket disclosed in the embodiments of this application will be explained and described in detail.

[0042] Among them, such as Figure 1 As shown, the main cable assembly 100 may include at least two parallel main cables 101 for laying the photovoltaic panel on the main cables 101 and rigidly connecting it to the main cables 101. The main cables 101 may be, but are not limited to, two parallel cables, or may include three, four, or more, to ensure the stability of the photovoltaic panel connection. It should be noted that when there are three main cables 101, the middle main cable 101 can be positioned at the rotation center axis of the photovoltaic panel, thus preventing the middle main cable 101 from rotating synchronously with the photovoltaic panel.

[0043] like Figure 1 and Figure 2 As shown, the support assembly 200 may include at least two to bear the tension from the main cable assembly 100 and transmit it to the ground foundation 500. Of course, the support assembly 200 may be of two, but not limited to three, four or more, to form a multi-span flexible photovoltaic tracking support. The specific number of support assemblies 200 may be determined according to the span of the flexible photovoltaic tracking support.

[0044] like Figure 2 As shown, the drive assembly 300 may include a rotating beam 301 and a drive member. The two ends of the main cable assembly 100 may be anchored to the rotating beam 301 respectively, and the rotating beam 301 is rotatably mounted on the support assembly 200. The drive member is connected to the rotating beam 301 for transmission, so as to drive the rotating beam 301 to rotate, thereby driving the photovoltaic panel on the main cable 101 to rotate, thereby adjusting the angle of the photovoltaic panel to ensure a larger effective light-receiving area of ​​the photovoltaic panel and improve power generation efficiency.

[0045] To improve the wind resistance and stability of flexible photovoltaic tracking brackets, such as Figure 1As shown, one or more wind-resistant components 400 are installed on the flexible photovoltaic tracking bracket. The wind-resistant component 400 may include a wind-resistant bracket 401, which is connected to the main cable assembly 100. A damper 402 may be installed on the wind-resistant bracket 401, thereby improving the wind resistance performance of the flexible photovoltaic tracking bracket. At the same time, the damper 402 can absorb the energy generated by vibration and impact, reducing the risk of microcracks and damage to the photovoltaic panel, thus enabling the flexible photovoltaic tracking bracket to have wind resistance and vibration reduction capabilities, and improving the stability of the flexible photovoltaic tracking bracket.

[0046] In some embodiments, such as Figure 1 As shown, the wind-resistant component 400 may further include a wind-resistant cable 403, which may be located below the main cable component 100, with both ends of the wind-resistant cable 403 fixed to the support component 200. The two sides of the wind-resistant support 401 are connected to the wind-resistant cable 403 and the main cable component 100 respectively to form an integrated spatial structure, thereby improving the overall stability of the flexible photovoltaic tracking support. For ease of understanding, the upper and lower sides of the wind-resistant support 401 are defined as the first side and the second side, respectively. The first side of the wind-resistant support 401 is rigidly connected to each of the main cables 101 of the main cable component 100, and the second side of the wind-resistant support 401 is rigidly connected to the wind-resistant cable 403, thus forming an integrated spatial structure. This improves the overall stability of the flexible photovoltaic tracking support, effectively resisting the torsion and collision of the photovoltaic panel by wind loads, snow loads, and gravity loads, reducing the risk of damage to the photovoltaic panel due to wind force, and also reducing the risk of microcracks and overturning of the photovoltaic panel.

[0047] The wind-resistant cable 403 can be one, but not limited to one; two, three, four, or more cables can also be used to improve the overall stability of the flexible photovoltaic tracking bracket. Optionally, one wind-resistant cable 403 can be used, and the wind-resistant cable 403 is located at the lower middle position of the two main cables 101, so that the first side of the wind-resistant bracket 401 can be rigidly connected to each of the main cables 101, and the second side of the wind-resistant bracket 401 can be rigidly connected to the wind-resistant cable 403, thereby forming a three-cable spatial structure to improve the overall stability of the flexible photovoltaic tracking bracket.

[0048] In some embodiments, such as Figure 3 and Figure 4As shown, the wind-resistant support 401 may include a movable rod 4011, a fixed rod 4012, and a support member 4013. The movable rod 4011 can be located on the first side of the wind-resistant support 401 and rigidly connected to each main cable 101 via a U-shaped buckle. The fixed rod 4012 can be located on the second side of the wind-resistant support 401 and rigidly connected to the wind-resistant cable 403 via a U-shaped buckle. Both ends of the fixed rod 4012 can be connected and fixed to the ground foundation 500 via cables to ensure the stability of the wind-resistant support 401 and improve the wind resistance performance of the flexible photovoltaic tracking support. Furthermore, one end of the support member 4013 can be fixed to the fixed rod 4012, and the other end of the support member 4013 can be rotatably connected to the movable rod 4011, so that the movable rod 4011 can rotate synchronously with the main cable 101, avoiding torsional loads on the wind-resistant support 401 and ensuring its stability. Optionally, as... Figure 3 and Figure 4 As shown, the support member 4013 may include at least two support rods 4014 arranged at a preset included angle, and each support rod 4014 intersects the movable rod 4011 and is rotatably connected to the movable rod 4011 through a slewing connector 4015. Two support rods 4014 may be used to form a triangular stable support structure, which improves the overall stability of the wind-resistant support 401 while ensuring the rotatability of the movable rod 4011. Of course, three, four, or more support rods 4014 may also be used to form multiple triangular stable support structures, thereby further improving the stability of the wind-resistant support 401.

[0049] In some embodiments, such as Figure 3 As shown, each support rod 4014 intersects with and is fixedly connected to the rotary connector 4015. Simultaneously, the movable rod 4011 is hinged to the rotary connector 4015 via a hinge shaft, allowing the movable rod 4011 to rotate around the hinge shaft along with the main cable 101. Optionally, the rotary connector 4015 can be located at the middle position of the movable rod 4011 to ensure more stable rotation of the movable rod 4011 under the action of the main cable 101.

[0050] In some embodiments, such as Figure 4 and Figure 5As shown, the rotary connector 4015 can adopt an arc-shaped structure, and both ends of the rotary connector 4015 can be fixed to the movable rod 4011 respectively. At the same time, the rotary connector 4015 is provided with an arc-shaped slide rail 4016. Each support rod 4014 can intersect at the arc-shaped slide rail 4016, and the end of each support rod 4014 is fixed with a sliding shaft passing through the arc-shaped slide rail 4016. The sliding shafts at the ends of each support rod 4014 can be limited within the arc-shaped slide rail 4016 by spacers 4017, so as to prevent the sliding shafts at the ends of each support rod 4014 from coming off the arc-shaped slide rail 4016. Thus, each support rod 4014 can slide along the arc-shaped slide rail 4016, so that the movable rod 4011 can follow the main cable 101 to rotate around the rotary connector 4015.

[0051] It should be noted that, as Figure 1 As shown, when there are multiple flexible photovoltaic tracking brackets and they are arranged in parallel, the wind-resistant cable 403 of each flexible photovoltaic tracking bracket can be fixed to the fixing rod 4012 of the same wind-resistant bracket 401. The two ends of the fixing rod 4012 are respectively fixed to the ground foundation 500 by cables, so that each flexible photovoltaic tracking bracket can form an overall wind-resistant structure, improving the overall stability and wind resistance of each flexible photovoltaic tracking bracket.

[0052] In some embodiments, such as Figure 3 and Figure 4 As shown, the two ends of the damper 402 can be connected to the movable rod 4011 and the fixed rod 4012 respectively. Optionally, an upper damping seat can be fixed to the movable rod 4011 with bolts or other fasteners, and a lower damping seat can be fixed to the fixed rod 4012 with bolts or other fasteners. This allows the two ends of the damper 402 to be hinged to the upper and lower damping seats respectively, so that the damper 402 can absorb the energy generated by vibration and impact, reduce the risk of microcracks and damage to the photovoltaic panel, and enable the flexible photovoltaic tracking bracket to have wind resistance and vibration reduction capabilities, thereby improving the stability of the flexible photovoltaic tracking bracket.

[0053] In some embodiments, such as Figure 2 As shown, the support assembly 200 includes columns 201, connecting components 202, and stay cables 203. Two columns 201 may be included, with the connecting component 202 connecting the two columns 201. A rotating beam 301 is rotatably mounted on the connecting component 202, allowing the rotating beam 301 to rotate relative to the connecting component 202, thereby rotating the main cable 101 and adjusting the angle of the photovoltaic panel. One end of the stay cable 203 is connected to the top of the column 201, and the other end is connected to the ground foundation 500, forming a stay cable structure to ensure the stability of the support assembly 200.

[0054] In some embodiments, such as Figure 2 As shown, the connecting assembly 202 may include a longitudinal beam 2021 and at least two crossbeams 2022. The two ends of the crossbeams 2022 are respectively connected to the columns 201, and the longitudinal beam 2021 is connected between the two crossbeams 2022. The rotating beam 301 is hinged to the longitudinal beam 2021. At the same time, arc-shaped guide rails 204 are symmetrically arranged on both sides of the longitudinal beam 2021, and the two ends of the rotating beam 301 are provided with bearings 3011 that can roll along the arc-shaped guide rails 204, so that when the rotating beam 301 rotates, the bearings 3011 at both ends of the rotating beam 301 can roll along the arc-shaped guide rails 204. Optionally, an L-shaped connector can be provided at the middle position of the longitudinal beam 2021 on the side away from the main cable 101, and a space for accommodating the rotating beam 301 can be formed between the L-shaped connector and the longitudinal beam 2021. The rotating beam 301 can be hinged to the space between the L-shaped connector and the longitudinal beam 2021 through a hinge shaft. At the same time, the center of the two arc-shaped guide rails 204 coincides with the hinge shaft, thereby ensuring that the bearings 3011 at both ends of the rotating beam 301 roll along the arc-shaped guide rails 204.

[0055] In some embodiments, baffles that limit the bearings 3011 at the ends of the rotating beam 301 can be respectively provided on both sides of the arc-shaped guide rail 204. This allows the bearings 3011 at the ends of the rotating beam 301 to be limited by the baffles on both sides of the arc-shaped guide rail 204, thereby ensuring the stability of the bearings 3011 at both ends of the rotating beam 301 as they roll along the arc-shaped guide rail 204.

[0056] In some embodiments, the driving component may include an electric push rod, one end of which may be mounted on the rotating beam 301, and the other end of which may be fixed to the bracket assembly 200, so that the rotation of the rotating beam 301 can be realized through the extension and retraction of the electric push rod. Of course, the driving component may also be a drive motor, a telescopic cylinder, or a tilting cylinder, etc., which are not limited herein.

[0057] This application also discloses a photovoltaic system, including a photovoltaic panel and a flexible photovoltaic tracking bracket as disclosed in the above embodiments. Therefore, it possesses all the technical effects of the aforementioned flexible photovoltaic tracking bracket, which will not be repeated here. Multiple photovoltaic panels can be used, each laid on the main cable assembly 100 and rigidly connected to each main cable 101 of the main cable assembly 100. The angle of the photovoltaic panel can be adjusted by rotating the main cable 101, ensuring a larger light-receiving area and improving power generation efficiency.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application.
