Description

Technical Field

[0001] This utility model relates to the field of flexible photovoltaic support technology, specifically to a flexible photovoltaic support end stabilization device that uses a standard bolt group and has an adjustable angle. Background Technology

[0002] As the global energy structure transitions towards clean and low-carbon practices, photovoltaic (PV) power generation, as one of the core forms of renewable energy utilization, has expanded its application scenarios from traditional flat sites to complex terrains such as mountains, hills, and slopes. Flexible PV support systems, with their advantages of light weight, strong adaptability, and minimal damage to terrain, have become the preferred solution for constructing PV power plants in complex terrains. The stable support and angle adjustment capabilities at the ends of the support systems directly determine the light-receiving efficiency of the PV modules and the long-term operational reliability of the system.

[0003] Currently, the end stabilization devices of flexible photovoltaic supports still face many technical bottlenecks in practical applications: Insufficient flexibility and adaptability in angle adjustment: Existing devices mostly adopt rigid connection structures with fixed angles, or can only achieve small-range angle adjustments, making it difficult to adapt to the differentiated requirements of photovoltaic module tilt angles under different regional sunshine conditions and complex terrain slopes. Some adjustable devices rely on customized connectors, which not only increases design and manufacturing costs, but also limits the adjustment range, failing to meet the installation needs of winter lighting in high-latitude regions or complex slopes, thus making it difficult to maximize the power generation efficiency of photovoltaic systems.

[0004] The unreasonable design of the force transmission structure leads to insufficient safety: In most cases, the angle adjustment mechanism and the stabilizing support mechanism at the end of the support frame are set independently, and the two indirectly transmit the load through multiple sets of intermediate connectors, resulting in a long force transmission path and dispersed stress distribution. Under extreme weather conditions such as strong winds, rain, and snow, the intermediate connectors are prone to deformation and loosening due to concentrated stress, which may even cause angle adjustment failure or instability at the end of the support frame, seriously affecting the structural safety and service life of the photovoltaic system.

[0005] Low standardization and high installation and maintenance costs: Existing installations often use non-standard, custom-made components for core connections, such as specialized pins and irregularly shaped connecting plates. This not only leads to complex supply chain management and long production cycles but also increases reliance on specialized tools and skills for on-site installation, resulting in low construction efficiency. Furthermore, the poor versatility of these custom-made components makes replacement difficult during later maintenance, further increasing the operation and maintenance costs of photovoltaic power plants.

[0006] Therefore, developing a flexible photovoltaic support end stabilization device that can achieve a wide range of angle adjustment, a clear force transmission path, a high degree of standardization, and safety and reliability has become a key technical requirement for adapting to the construction needs of photovoltaic power plants in complex terrain and improving the overall benefits of photovoltaic systems.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. It should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other indicating directions or positional relationships are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model.

[0029] Example 1: like Figure 1 , Figure 2 As shown, this utility model provides a flexible photovoltaic bracket end stabilization device. The upper end of the end column assembly 1 is fixed with a support base 4, the upper position of the support base 4 is fixed with an angle adjustment system 5, and the lower position of the support base 4 is fixed with an end inclined pull system 6.

[0030] Combination Figures 1 to 3 As shown, the support base 4 includes a base plate 41, which is a square steel plate. The base plate 41 is welded and fixed to the inclined surface at the upper end of the end column assembly 1. A pair of side plates 42 are welded to the base plate 41. The side plates 42 are V-shaped steel plates with the side away from the base plate 41. The upper ends of the two side plates 42 have upper through holes for installing the angle adjustment system 5, and the lower ends of the two side plates 42 have lower through holes for the end inclined tensioning system 6. The tensioning pad 43 is attached to and welded to the V-shaped edges of the two side plates 42, forming a stable frame structure together with the base plate 41. The tensioning pad 43 has an elongated hole in the middle for the component cable 55 in the angle adjustment system 5 to pass through.

[0031] When tensioning the component cable 55, the tensioning device can be fixed on the tensioning pad 43 to complete the tensioning work; the elongated hole provides sufficient operating space for the angle adjustment system 5 to adjust the angle, ensuring that the angle adjustment system 5 can be freely rotated and adjusted within the range of -30° to 60°.

[0032] Combination Figures 1 to 4 As shown, the angle adjustment system 5 includes an adjustable pin 51, on which an adjustable sleeve 52 is fitted. A through hole is formed between the adjustable pin 51 and the adjustable sleeve 52. The adjustable pin 51 is a round steel component. Approximately 10mm from the end of each end of the adjustable pin 51, a round hole is formed perpendicular to the cut surface. This round hole is used to install the first standard bolt set. The adjustable pin 51 is centrally installed within the upper through hole of the two side plates 42. The adjustable sleeve 52 is positioned between the adjustable pin 51 and the hole wall of the side plate 42. This adjustable sleeve 52 is used to avoid stress concentration and protect the structural integrity of the upper through hole of the side plate 42.

[0033] The adjustable pad 54 is a square steel plate with three through holes. The two through holes at both ends are used to install the first standard bolt set. The first standard bolt set consists of one first standard bolt 53, one flat washer, one spring washer, and two nuts, which connect the adjustable pin 51 and the adjustable pad 54 together. The component cable 55 first passes through the through hole in the middle of the adjustable pad 54, then through the through hole of the adjustable sleeve 52 and the adjustable pin 51, and finally exits through the elongated hole of the tensioning pad 43. After the component cable 55 is tensioned to the correct position, it is fixed by the anchor 56 on one side of the adjustable pad 54.

[0034] Example 2: Based on the above embodiment one, combined with Figures 1 to 5 As shown, the end cable-stayed system 6 has a similar structure to the angle adjustment system 5.

[0035] The end bracing system 6 includes a bracing pin 61, on which a bracing sleeve 62 is fitted. Both ends of the bracing sleeve 62 are installed in the lower through holes of the side plates 42 on both sides. A flat surface is formed on the circumference of both ends of the bracing pin 61, with a through hole in this surface. A second standard bolt 63, in conjunction with a flat washer, a spring washer, and a nut, connects the bracing pin 61 and the bracing pad 64. A bracing rod 65 passes through the center hole of the bracing pad 64. The bracing rod 65 is made of precision-rolled threaded steel or prestressed steel strand, and its two ends are fastened by anchors or double-reinforced nuts 66. The top of the bracing rod 65 is anchored to the bracing pad 64, and the bottom is fixedly connected to the mounting foundation.

[0036] Example 3: Based on the above embodiment one, combined with Figure 1 As shown, each pair of end column assemblies 1 forms a group, and a crossbeam assembly 2 is connected between the two end column assemblies 1.

[0037] Combination Figure 1 , Figure 2 and Figure 6 As shown, the end column assembly 1 includes a prestressed concrete precast pipe pile 11. The pile top sealing plate 12 is a circular steel plate, which is welded to the steel plate reserved at the top of the precast pipe pile 11 to form a closed and connected foundation for the pile top of the precast pipe pile 11. The end steel column 13 is made of standard H-beams, cut into two sections at a 45° angle from the middle, forming an inclined surface at the top; the flange of the end steel column 13 extends 100mm to provide reliable support and constraint for the support seat 4. The steel column stiffening plate 14 is welded and fixed to the middle of the end steel column 13 to improve the overall structural stability of the end steel column 13. The straight end of the lower end of the end steel column 13 is fixed to the pile top sealing plate 12 by welding, and the support seat 4 is welded to the inclined surface at the upper end of the end steel column 13. The angle adjustment system 5 is connected to the end of the support seat 4 near the high position of the inclined surface, and the end diagonal bracing system 6 is connected to the end of the support seat 4 near the low position of the inclined surface. During construction, the tilt angle of the photovoltaic modules can be adjusted by adjusting the height difference between the two sets of end steel columns 13.

[0038] Combination Figure 1 , Figure 2 and Figure 7As shown, the crossbeam system 2 connects the end steel columns 13 of the two end column assemblies 1 and bears the load of the load-bearing cable. The crossbeam assembly 2 includes a crossbeam 21, which is made of I-beam and placed laterally. Its two ends are welded and fixed to the lower part of the end steel columns 13 on both sides. An elongated hole is opened in the middle of the inner flange of the crossbeam 21. This elongated hole facilitates the insertion of the load-bearing cable 24 and prevents friction damage between the load-bearing cable 24 and the flange of the crossbeam 21 when the load-bearing cable 24 sways. The load-bearing cable 24 is a prestressed steel strand. After the end of the load-bearing cable 24 passes through the elongated hole, it is pressed and fixed on the inner side of the flange of the crossbeam 21 by a compression anchor 23. Two crossbeam stiffening plates 22 are set on both sides of the compression anchor 23 and welded to the flanges on both sides to strengthen the structure of the crossbeam 21 and ensure that the crossbeam assembly 2 can stably bear the load and work normally.

[0039] As can be seen from the above embodiments, the flexible photovoltaic support end stabilization device of this utility model solves the shortcomings of traditional devices, which require many customized connectors, have fixed angles, and are difficult to adapt to different installation scenarios and photovoltaic module tilt angle requirements. This utility model, based on a standard bolt group connection angle adjustment system and an end inclined tension system, features a simple structure, controllable cost, convenient angle adjustment, strong adaptability, and stable reliability, providing technical support for the efficient deployment and long-term stable operation of flexible photovoltaic support systems.
