[0004] However, affected by climate change, soil at the work site and flexible support structure, in rainy seasons, the soil absorbs a large amount of water, becoming loose and causing loss. At this time, the supporting force of the flexible support drops sharply and cannot provide strong support. This causes the flexible support to collapse easily under the erosion of rainwater, causing serious economic losses. Summary of the invention

At this time, the supporting force of the flexible support drops sharply and cannot provide strong support. This leads to the flexible support being easily collapsed under the erosion of rainwater, causing serious economic losses.
[0006] In order to achieve the above object, the present invention adopts the following technical solutions: In a first aspect, an end support structure of a flexible bracket is provided, comprising: The longitudinal support units are provided in two groups, and the two groups of longitudinal support units are connected by steel cables; A base having a mounting hole formed thereon, wherein the external casting block is cast in the mounting hole; Wherein, an inner casting block is cast in the longitudinal support unit, and the outer casting block and the inner casting block are cast integrally.

[0026] Solar flexible brackets, with their innovative four-dimensional installation technology of suspension, pulling, hanging and supporting, can flexibly realize all-round free erection, bringing unprecedented support innovation to distributed photovoltaic power generation systems. Compared with traditional steel frame structures, flexible brackets use less material and lighter load-bearing design, which significantly reduces the cost and greatly shortens the construction period. Its excellent pre-installation performance reduces the stringent requirements on the site foundation, making installation more convenient and efficient.
[0027] In distributed photovoltaic power generation systems, flexible brackets play a vital role, not only improving the flexibility and adaptability of the system, but also optimizing the layout of energy utilization. It is particularly worth mentioning that the flexible bracket, with its unique advantages, perfectly adapts to various complex terrains such as ordinary mountains, barren slopes, ponds, fish ponds and woodlands, achieving comprehensive coverage of large-span application sites and further broadening the application boundaries of photovoltaic power generation.
[0028] However, affected by climate change, soil at the work site and flexible support structure, in rainy seasons, the soil absorbs a large amount of water, becoming loose and causing loss. At this time, the supporting force of the flexible support drops sharply and cannot provide strong support. This causes the flexible support to collapse easily under the erosion of rainwater, causing serious economic losses.
[0029] In order to solve the above technical defects, the inventor provides an end support structure and method of a flexible bracket.
[0030] The present invention is further described in detail below in conjunction with the accompanying drawings: like Figure 1-Figure 2 As shown, in the first aspect, an embodiment of the present invention provides an end support structure of a flexible bracket, including a longitudinal support unit 9, which is provided with two groups. The two groups of longitudinal support units 9 are connected by a steel cable 12 to form a stable triangular support structure, which significantly improves the overall wind pressure resistance, snow load resistance and rain resistance of the flexible bracket; a foundation 6, which is provided with a mounting hole 7, and an external casting block 8 is cast in the mounting hole 7; wherein, an internal casting block 10 is cast in the longitudinal support unit 9, and the external casting block 8 and the internal casting block 10 are cast as a whole, realizing the internal and external combination and overall casting method, further enhancing the integrity and stability of the support structure, ensuring that the flexible bracket is not easy to deform, loosen and collapse in long-term use, and through the excellent durability of materials such as concrete, it effectively resists the influence of natural factors such as environmental erosion and weathering, and extends the service life of the support structure. By constructing the foundation 6 on the work site, the erosion of the bottom of the flexible bracket and the bottom soil by rainwater is avoided, so that the flexible bracket supported by the support structure can be conveniently fixed on various terrains and foundations, thereby improving the scope of application. As Figure 1As shown, two groups of longitudinal support units 9 are symmetrically arranged, and the number of each group of longitudinal support units 9 is multiple. Multiple longitudinal support units 9 correspond to each other through steel cables 12, and between two adjacent steel cables 12, they are used to support the flexible bracket at the bottom of the photovoltaic panel 14; in this process, the two groups of longitudinal support units 9 arranged symmetrically can evenly disperse the pressure from the upper part of the flexible bracket and the external environment, such as wind force, snow load and rain impact, etc., effectively avoiding structural damage caused by excessive force on a single point; and multiple longitudinal support units 9 are connected one by one through steel cables 12 to form a tight and stable support network. This multi-point connection method not only increases the overall rigidity of the flexible bracket, but also improves its lateral force resistance and torsion resistance, so that the flexible bracket can still maintain a stable shape under complex environmental conditions, and enhances the stability and bearing capacity of the entire flexible bracket. In addition, since each group of longitudinal support units 9 includes multiple units, and these units are flexibly connected by steel cables 12, the span, height and angle of the support structure can be easily adjusted according to actual needs, so that it can better adapt to different installation scenarios and photovoltaic panel 14 layouts, and improve flexibility and adaptability. Furthermore, the longitudinal support unit 9 is provided with an anchor installation hole 15, and the two ends of the steel cable 12 are provided with a prestressed anchor 1, which is engaged with the anchor installation hole 15 to form a stable mechanical locking mechanism, which can effectively prevent the steel cable 12 from slipping or loosening during the force-bearing process, thereby ensuring the overall stability and safety of the support structure. At the same time, the prestressed anchor 1 can not only firmly fix the steel cable 12, but also effectively transfer the prestress to the longitudinal support unit 9. This efficient prestressed transfer mechanism helps to enhance the overall stiffness and bearing capacity of the support structure, so that it can better resist external loads and deformation. Finally, the snap-fit design of the prestressed anchor 1 and the anchor mounting hole 15 simplifies the installation process, reduces the installation difficulty, and can also adjust the tension of the steel cable 12 to a certain extent, so as to optimize the stress state of the support structure according to actual needs. When the support structure needs maintenance or replacement of parts, the snap-fit connection between the prestressed anchor 1 and the anchor mounting hole 15 makes the related operations more convenient. Only by loosening the snap-fit part, the steel cable 12 or the longitudinal support unit 9 can be easily replaced or repaired, reducing the maintenance cost and difficulty. Figure 2 As shown, the longitudinal support unit 9 is a hollow metal component, and the cross section of the longitudinal support unit 9 is rectangular or annular, so that it can still maintain a high structural strength and stability.
[0031] like Figure 1As shown, the support structure also includes a middle bracket 4, which is vertically installed on the top of the foundation 6 and is arranged in sequence at intervals along the width direction of the foundation 6. The multiple middle brackets 4 are connected by a support steel frame 11; wherein, a support cable 3 is provided on the support steel frame 11, and a ring 5 is installed on the support cable 3, and a steel cable 12 passes through the ring 5. The middle bracket 4 is vertically installed on the top of the foundation 6 and is arranged in sequence at intervals along the width direction of the foundation 6, forming a stable support point, effectively dispersing the load, and improving the stability of the entire support structure, and the support steel frame 11 connects the multiple middle brackets 4 to form an overall frame, further enhancing the stability and wind and earthquake resistance of the structure. The combined use of the support cable 3 and the steel cable 12, and the flexible connection achieved through the ring 5, not only increases the bearing capacity of the support structure, but also can adapt to certain deformations, and improves the toughness of the structure. The steel cable 12 passes through the ring 5 to form a prestressed structure. By adjusting the tension of the steel cable 12, the stress state of the support structure can be further optimized to improve its bearing capacity. Figure 1 As shown, the middle bracket 4 is axially perpendicular to the supporting steel frame 11, and the ring 5 is located between two adjacent middle brackets 4. The axially perpendicular layout of the middle bracket 4 and the supporting steel frame 11 ensures the direct and effective transmission of force in the structure, reduces the dispersion and distortion of force, and makes the entire supporting structure more stable and reliable; the ring 5 is located between two adjacent middle brackets 4, serving as a fulcrum for the steel cable 12, further optimizing the distribution of force and ensuring the overall stability and bearing capacity of the supporting structure.
[0032] like Figure 1 and Figure 2 As shown, anchor rods 13 are provided at both ends of the foundation 6, and mounting rings 2 are provided at both ends of the steel cable 12 near the foundation 6. The mounting rings 2 are sleeved on the top of the anchor rods 13. The anchor rods 13, as fixing elements that penetrate into the foundation 6, provide a solid support foundation for the entire support structure. By sleeved the mounting rings 2 on the top of the anchor rods 13, the steel cable 12 is firmly fixed to both ends of the foundation 6, thereby significantly enhancing the stability of the entire support structure. At the same time, under the action of external loads such as wind or earthquake, the support structure may be subjected to a large force, and the combined use of the anchor rods 13 and the mounting rings 2 provides additional constraints for the steel cable 12, enabling it to better resist these external loads, thereby improving the wind and earthquake resistance of the entire support structure.
[0033] In a second aspect, an embodiment of the present invention provides a method for manufacturing an end support structure of a flexible stent, such as Figure 3 As shown, including: S101, excavating an installation hole and casting a formwork in the installation hole; illustratively, first, selecting an installation site for the flexible bracket, then excavating the installation hole 7 according to the design drawing, compacting the bottom and side walls of the installation hole 7, installing a casting formwork on the inner wall of the installation hole 7, and after completion, checking the verticality, horizontality and stability of the casting formwork to ensure that it meets the design requirements.
[0034] S102. Tie a steel cage in the formwork to support the longitudinal support unit. For example, tie the steel cage of the load-bearing column in the formwork. The specifications, quantity, spacing, etc. of the steel bars should comply with the requirements of the design drawings and construction specifications. After the steel cage is tied, a concealed project inspection should be carried out to ensure that the quality of the steel bars is qualified.
[0035] S103, weld the vertical reinforcement to the embedded steel bar, and pour concrete on the longitudinal support unit. Exemplarily, clean the rust and cement slurry on the embedded steel bar, align the vertical line with the center point of the column, use a crane to hoist the vertical reinforcement into place, mark the welding position, and weld it to the embedded steel bar in sequence. At the same time, according to the vertical line, install the stirrups to ensure that the position of the steel skeleton does not deviate from the center of the column. Before welding the steel bar, use a wire brush to remove oil stains, rust, double-sided seams 5d, width ≥0.7d, weld depth ≥0.3d, and pour concrete in the longitudinal support unit 9; secondly, adopt layered pouring, the layer thickness is 30cm~50cm, insert the vibrator, and construct synchronously according to the effective diameter of 30cm~40cm, vibrate until the sinking stops without significant bubbles rising, the surface is flat and uniform, and a thin layer of cement slurry is presented. Finally, it also includes maintenance steps, ultrasonic testing steps and anti-corrosion treatment steps; after pouring, the number of watering times per day should be enough to keep the concrete surface moist. The pier body should be sealed and wrapped with plastic film to reduce water evaporation, and insulation measures should be taken. Watering should be done 2 to 4 times a day. Coupling agent is applied to the surface of the ultrasonic probe. The spacing between measuring points in the pipe fittings can be set to 50mm to 100mm. In non-critical parts, the spacing can be appropriately relaxed to 150mm to 200mm. Multiple coats of paint are applied to the surface of the longitudinal support unit 9, including primer, midcoat and topcoat. Each coat needs to wait for the previous coat to dry, and ensure that the coating is uniform, smooth, bubble-free and non-shedding. In summary, by constructing the foundation 6 at the work site, rain erosion is avoided, and the two groups of longitudinal support units 9 are connected by steel cables 12 to form a stable triangular support structure, which significantly improves the overall resistance of the flexible bracket to wind pressure, snow load, and rain. At the same time, the external casting block 8 is cast in the mounting hole 7 on the foundation 6, and the internal casting block 10 is cast in the longitudinal support unit 9, realizing the internal and external combination and overall casting method, further enhancing the integrity and stability of the support structure, ensuring that the flexible bracket is not easily deformed, loosened, and collapsed during long-term use, and solving the defects of the prior art.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit its protection scope. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that after reading the present invention, those skilled in the art can still make various changes, modifications or equivalent substitutions to the specific implementation methods of the invention, but these changes, modifications or equivalent substitutions are all within the protection scope of the pending claims of the invention.
