Description

Technical Field

[0001] This utility model relates to the technical field of end support equipment for three-cable flexible photovoltaic brackets, and in particular to an end support structure for a three-cable flexible photovoltaic bracket. Background Technology

[0002] Flexible photovoltaic (PV) supports serve as the core support system for solar power plants, stabilizing the photovoltaic modules. Cable-stayed PV supports consist of side anchors, side column supports, central supports, cables, and wind-resistant structures. The side column supports, located at the system ends, play a crucial role in constraining the ends of the main cables. Traditional cable-stayed structure designs typically employ a double-column, double-pile scheme, requiring both side piles to be on the same horizontal plane and demanding high precision in their spacing. However, in complex terrain conditions such as mountainous areas, especially with steep slopes, the horizontal alignment and spacing control of the side piles become challenging construction issues, easily leading to reduced installation efficiency and increased costs.

[0003] When the demand for flexible photovoltaic (PV) support structures is upgraded to a three-cable structure, the system complexity increases further. The connection node between the third cable and the column needs to be redesigned, often requiring the addition of special connectors or complex structures, leading to a significant increase in material costs. At the same time, the difficulty of installation and maintenance also increases. In addition, the existing connection nodes between the main cable and the side columns generally lack the ability to adapt to slope changes, making it difficult to flexibly adapt to different terrain elevations, thus restricting the widespread application of cable-stayed PV support structures in diverse landforms. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose an end support structure for a three-cable flexible photovoltaic bracket, so as to solve the problem that the connection nodes between the main cable and the side column in the end support structure of the flexible photovoltaic bracket generally lack adaptive slope capability, making it difficult to flexibly adapt to different terrain elevation changes and the installation process is difficult.

[0005] To achieve the above objectives, this utility model provides an end support structure for a three-cable flexible photovoltaic bracket, including a side column and several sets of end support modules. Each end support module includes: a connecting mechanism with a connector and a locking component; the connector is connected to the side column via a plug-in connection; one end of the connector facing the side column has a connecting slot; the locking component is used to fix the connector and can adjust the distance between the connecting slot and the side column; a side anchor ring fixedly connected to the ground; and an end cable mechanism, one end of which is connected to the side anchor ring, and the other end of which is connected to the connecting slot.

[0006] In an optional example, the side column includes a column tube, the upper end of which is provided with a crossbeam, and a U-shaped plate for connecting the main cable is fixed on the crossbeam.

[0007] In an optional example, the sidewalls of the U-shaped upright are provided with reinforcing ribs that are fixedly connected to the crossbeams.

[0008] In one optional example, the U-shaped upright plate has a connecting hole that extends through the U-shaped upright plate along the length of the beam, and an angle adjustment component for connecting the main cable is inserted and fixed in the connecting hole.

[0009] In an optional example, the angle adjusting component includes a pin, with an outwardly extending retaining ring on the outer wall of the pin, both ends of the pin being inserted into connecting holes and extending out of the connecting holes, a cotter pin being inserted into the end of the pin located outside the connecting holes, a main pad being provided on the outer wall of the pin, and a main hole penetrating the pin being opened on the end face of the main pad.

[0010] In one alternative example, the connector is U-shaped, and the locking element has at least two sets and is connected to both ends of the connector by a threaded connection.

[0011] In an optional example, the crossbeam has two sets of first mounting holes that pass through the crossbeam for fixing the connector.

[0012] In an optional example, a cross guard plate is fixed on the cross beam, and two sets of second mounting holes are provided on the cross guard plate for fixing the connector. The centers of the first mounting hole and the second mounting hole coincide, and the connector passes through the first mounting hole and the second mounting hole.

[0013] In an optional example, the locking component includes a locking plate fitted onto the outer wall of the connector and a plurality of locking nuts. The locking nuts are fixedly connected to the connector by means of a threaded connection. One end of the locking plate abuts against the end of the crossbeam away from the locking groove, and the other end of the locking plate abuts against the locking nuts.

[0014] In an optional example, the end cable mechanism includes a side cable and diagonal tie assemblies fixed to both ends of the side cable, one set of the diagonal tie assemblies being connected to a side anchor ring, and the other set of the diagonal tie assemblies being connected to a connecting through groove.

[0015] The beneficial effects of this utility model are that the side columns adopt a single column form, which reduces the construction requirements of the side column pile foundation in the end support structure of the three-cable photovoltaic bracket, has a high adaptability to different mountain slopes, reduces the construction difficulty and installation cost of the end support structure of the three-cable photovoltaic bracket, and the adjustment mechanism of the connecting slot and locking part allows for on-site fine adjustment of installation errors, improving the installation flexibility of the flexible photovoltaic bracket end support structure, and can adapt to the installation terrain with slopes. At the same time, the side columns and several sets of end support modules form a triangular support structure, which significantly improves the wind resistance and earthquake resistance of the flexible photovoltaic bracket, and is suitable for extreme environments such as high altitude and coastal areas.

[0026] In one embodiment, please refer to Figures 1 to 2 As shown, the present invention provides an end support structure for a three-cable flexible photovoltaic bracket, including side columns 1 and several sets of end support modules. The side columns 1 are fixedly connected to the ground via embedded parts and are used to connect the main cables 4, serving as the core vertical unit of the overall support structure and bearing the load transfer of the main cables 4 and the upper photovoltaic modules. The end support modules can be adjusted according to the number of main cables 4; preferably, three sets of end support modules are used, which match the three-cable flexible photovoltaic bracket to ensure the structural stability of the flexible photovoltaic bracket.

[0027] The end support module includes:

[0028] The connecting mechanism includes a connector 6 and a locking component. The connector 6 is connected to the side column 1 via a plug-in connection. A connecting slot is provided at the end of the connector 6 facing the side column 1. The locking component is used to fix the connector 6 and can adjust the distance between the connecting slot and the side column 1. The adjustable volume of the connecting slot, achieved through the locking component, allows the end cable mechanism to rotate and move within a wide range, facilitating the installation of the connecting mechanism and the end cable mechanism, and reducing the installation difficulty of the end support structure of the three-cable flexible photovoltaic bracket.

[0029] The side anchor ring 12 is fixedly connected to the ground by pre-embedding. The side anchor ring 12 adopts a ring structure, which facilitates the quick assembly and disassembly of the end cable mechanism.

[0030] The end cable mechanism is connected at one end to the side anchor ring 12 and at the other end to the connecting through groove, forming a triangular force-bearing structure that effectively disperses the horizontal and vertical loads generated by the main cable and photovoltaic modules.

[0031] Specifically, in this example, the side column 1 adopts a single column form, which reduces the construction requirements of the pile foundation of the side column 1 in the end support structure of the three-cable photovoltaic bracket. It has high adaptability to different mountain slopes, reduces the construction difficulty and installation cost of the end support structure of the flexible photovoltaic bracket, and the adjustment mechanism of the connecting slot and locking part allows for fine-tuning of installation errors on site, improving the installation flexibility of the end support structure of the flexible photovoltaic bracket. It can adapt to the installation terrain with slopes. At the same time, the side column 1 and several sets of end support modules form a triangular support structure, which significantly improves the wind resistance and earthquake resistance of the flexible photovoltaic bracket, making it suitable for extreme environments such as high altitude and coastal areas.

[0032] In an optional example, please refer to Figures 1 to 6 As shown, the side column 1 includes a column tube 1-5, and a crossbeam 1-1 is provided at the upper end of the column tube 1-5. The crossbeam 1-1 is connected to the upper end of the column tube 1-5 by welding or bolting to form a stable lateral support platform, thereby enhancing the overall rigidity and torsional resistance of the side column 1.

[0033] A U-shaped vertical plate 1-3 for connecting the main cable 4 is fixed on the crossbeam 1-1 by welding or bolting.

[0034] Specifically, the column tube 1-5, the crossbeam 1-1, and the U-shaped plate 1-3 in this example adopt a modular design, which can be quickly assembled, shorten the construction cycle, reduce on-site cutting or adaptation work, and reduce labor and manufacturing costs.

[0035] In an optional example, please refer to Figures 1 to 6 As shown, the side wall of the U-shaped vertical plate 1-3 is provided with a reinforcing rib plate 1-4 that is fixedly connected to the crossbeam 1-1. The reinforcing rib plate 1-4 is connected to the upper end of the crossbeam 1-1 by welding or bolting to form a stable triangular support structure. The reinforcing rib plate 1-4 can be L-shaped, T-shaped, bent steel plate or angle steel.

[0036] Specifically, in this example, the cable load borne by the U-shaped vertical plate 1-3 is effectively transferred to the horizontal beam 1-1 and evenly distributed to the column tube 1-5 by the reinforcing rib plate 1-4, so as to avoid structural deformation caused by local stress concentration and enhance the stability of the side column 1 under lateral wind load.

[0037] In an optional example, please refer to Figures 1 to 6 As shown, a connecting hole is provided on the U-shaped vertical plate 1-3, which extends through the length of the crossbeam 1-1. An angle adjustment component for connecting the main cable 4 is inserted and fixed in the connecting hole.

[0038] Specifically, this example allows for quick on-site adjustment of the tilt angle of the main cable 4 through the connection holes of the U-shaped uprights 1-3 and the angle adjustment components, adapting to complex terrain or coping with wind load changes in different seasons.

[0039] In an optional example, please refer to Figures 1 to 6 As shown, the angle adjustment component includes a pin 5, with an outwardly extending retaining ring 8 on the outer wall of the pin 5. Both ends of the pin 5 are inserted into the connecting hole and extend out of the connecting hole. A cotter pin 9 is inserted into the end of the pin 5 located outside the connecting hole. A main pad 10 is provided on the outer wall of the pin 5, and a main hole penetrating the pin 5 is opened on the end face of the main pad 10. A main anchor is fixed to the outer wall of the main cable 4. The main cable 4 passes through the main hole and is fixed by the retaining ring 8 to restrict the axial movement of the pin 5 within the connecting hole. The cotter pin 9 is inserted into the extended end of the pin 5 to prevent the pin 5 from dislodging from the connecting hole, forming a double safety mechanism. The main pad 10 increases the force-bearing area of ​​the main cable 4 anchor, ensuring the service life of the pin 5.

[0040] Specifically, this example achieves continuous adjustment of the angle of the main cable 4 through the precise fit between the pin 5 and the connecting hole, ensuring the optimal tilt angle of the photovoltaic module under different terrains. Furthermore, the dual locking mechanism of the retaining ring 8 and the cotter pin 9 significantly enhances the system's resistance to deformation in extreme environments such as strong winds and earthquakes. At the same time, the structure of the pin 5 and the cotter pin 9 does not require welding or complex fasteners, and angle adjustment and locking can be completed by a single person, reducing construction difficulty and time.

[0041] In an optional example, please refer to Figures 1 to 6 As shown, the connector 6 is U-shaped, and the locking members have at least two sets, which are connected to both ends of the connector 6 by threaded connection. The connector 6 is formed by bending a steel wire; external threads are formed on the outer walls of both ends of the connector 6.

[0042] Specifically, the U-shaped connector 6 in this example has good flexibility and rigidity, and can adapt to the installation requirements of different angles and spaces. The threaded connection allows the locking part to be freely screwed in and out at both ends of the connector 6, and the width or length of the U-shaped opening can be quickly adjusted for easy and quick installation.

[0043] In an optional example, please refer to Figures 1 to 6 As shown, two sets of first mounting holes 1-11 are provided on the crossbeam 1-1 for fixing the connector 6.

[0044] Specifically, in this example, connector 6 can be fixed from both sides of the crossbeam 1-1 simultaneously, which enhances the adaptability and stability of connector 6. Furthermore, the through hole design allows connector 6 to directly penetrate the crossbeam 1-1, forming a double-sided clamping fixation, which significantly improves the connection strength and prevents the crossbeam 1-1 from twisting or loosening under stress.

[0045] In an optional example, please refer to Figures 1 to 6As shown, a horizontal guard plate 1-2 is fixed on the crossbeam 1-1. Two sets of second mounting holes 1-21 are provided on the horizontal guard plate 1-2 for fixing the connector 6. The center of the first mounting hole 1-11 and the center of the second mounting hole 1-21 coincide. The connector 6 passes through the first mounting hole 1-11 and the second mounting hole 1-21.

[0046] Specifically, in this example, connector 6 penetrates both layers of structure to form a "sandwich" fixation, which significantly improves the pull-out resistance and shear resistance of connector 6, preventing loosening or falling off. In addition, the guard plate, as an auxiliary support structure, shares the load with the crossbeam 1-1, reducing stress concentration in the crossbeam 1-1 and extending the overall service life.

[0047] In an optional example, please refer to Figures 1 to 6 As shown, the locking component includes a locking plate 7 fitted onto the outer wall of the connector 6 and several locking nuts. The locking nuts are fixedly connected to the connector 6 by means of threaded connection. One end of the locking plate 7 abuts against the end of the crossbeam 1-1 away from the locking groove, and the other end of the locking plate 7 abuts against the locking nuts.

[0048] Specifically, the locking nut of the threaded connection in this example provides high-strength fastening force, effectively preventing the connector 6 from shifting, loosening or rotating in the axial or radial direction. It is especially suitable for dynamic load environments such as vibration and impact. At the same time, the addition of the locking plate 7 avoids stress concentration between the crossbeam 1-1 and the locking nut, thus preventing the risk of failure.

[0049] In an optional example, please refer to Figures 1 to 6 As shown, the end cable mechanism includes a side cable 2 and inclined cable assemblies 3 fixed to both ends of the side cable 2. One set of inclined cable assemblies 3 is connected to the side anchor ring 12, and the other set of inclined cable assemblies 3 is connected to the connecting through groove. The inclined cable assembly 3 includes a U-bolt, a connecting plate 11, and several inclined cables. The connecting plate 11 has bolt through holes and inclined cable holes. Both ends of the U-bolt pass through the corresponding bolt through holes. The inclined cables are threaded onto the outer wall of the U-bolt. An inclined cable anchor is fixed to the outer wall of the side cable 2. The side cable 2 passes through the inclined cable holes and is fixed by the inclined cable anchor.

[0050] Specifically, in this example, the inclined cable assembly 3 adjusts the extension length of the U-bolt by rotating the inclined cable nut, thereby changing the distance between the U-bolt and the connecting slot. This achieves tension adjustment of the side cable 2, further enhancing the installation flexibility of the flexible photovoltaic bracket end support structure, allowing for on-site installation errors, and enabling it to adapt to sloping installation terrain. Furthermore, through the precise connection between the inclined cable assembly 3, the side anchor ring 12, and the connecting slot, a multi-point force distribution is formed, effectively dispersing the load, avoiding structural damage caused by stress concentration, and improving the overall deformation resistance.

[0051] Assembly process:

[0052] Step 1: First, install the side column 1 on the pile foundation of the side column 1, and then fix the connector 6 on the crossbeam 1-1.

[0053] Step 2: One end of the side cable 2 is threaded onto a cable tie 3, and the U-bolt on the cable tie 3 is fastened together with the connector 6.

[0054] Step 3: The other end of the side cable 2 is threaded onto another inclined cable assembly 3. The U-bolt on the inclined cable assembly 3 is fastened together with the side anchor ring 12. By tightening the inclined cable nut on the inclined cable assembly 3 and adjusting the U-bolt, the side cable is tightened, and the locking plate 7 on the connector 6 is tightly attached to the crossbeam 1-1.

[0055] Step 4: Install the pin 5 on the U-shaped vertical plate 1-3, and limit it within the U-shaped vertical plate 1-3 by the retaining ring 8 and the cotter pin 9.

[0056] Step 5: Use the main pad plate 10 to make the main cable 4 fit with the pin 5. The main cable 4 adapts to the mountain angle by rotating with the pin 5 until the installation is completed.

[0057] In summary, the side column 1 of this utility model adopts a single column form, which reduces the construction requirements for the pile foundation of the side column 1, has a high adaptability to different mountain slopes, reduces the construction difficulty and installation cost of the end support structure of the flexible photovoltaic bracket, and the adjustment mechanism of the connecting slot and locking part allows for fine adjustment of installation errors on site, improving the installation flexibility of the end support structure of the flexible photovoltaic bracket, and can adapt to the installation terrain with slopes. At the same time, the modular design enables rapid assembly, shortens the construction cycle, reduces on-site cutting or adaptation work, and reduces labor and manufacturing costs.
