Technical Field
[0001] This utility model relates to the field of photovoltaic panel support technology, and in particular to a central column for a large-span flexible support for photovoltaic panels. Background Technology
[0002] Under the global trend of energy structure transformation towards clean and low-carbon, the photovoltaic industry, as a core force in the field of renewable energy, is constantly expanding its application scenarios, gradually extending from traditional flat sites to complex terrains such as mountains, hills, and tidal flats. In order to adapt to the installation needs of large spans and irregular sites, large-span flexible photovoltaic panels have emerged. The central column of the large-span flexible photovoltaic panel support is set in the middle area of the support span, which plays the role of supporting steel strands, sharing the weight of photovoltaic modules, and transmitting external loads.
[0003] The central column of the large-span flexible photovoltaic support system is designed to meet the requirements of "lightweight and low-cost" flexible supports. The overall cost is controlled by simplifying the structural form and reducing material usage. During operation, it relies on its own column structure and the top connectors, along with steel strands, to transfer loads. This avoids, to some extent, the problems of poor site adaptability and high installation costs caused by the limited span of traditional rigid supports. In actual operation, the cross-sectional dimensions of the central column are generally small, while the loads it needs to bear are very complex, including the weight of the photovoltaic modules themselves and the tension generated by the steel strands. Due to the insufficient cross-sectional dimensions, the column's load-bearing capacity and deformation resistance are significantly reduced. Under long-term multiple loads, the column may bend and deform, and in severe cases, it may even break. This not only leads to damage to the photovoltaic modules and power generation interruption but also causes safety accidents, greatly affecting the stability and safety of the large-span flexible photovoltaic support system. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a central column for a large-span flexible support for photovoltaic panels. It aims to improve the problem in the prior art where the load-bearing capacity and deformation resistance of the column are greatly reduced due to insufficient cross-sectional dimensions. Under long-term multiple loads, the column will bend and deform, resulting in damage to photovoltaic modules, power generation interruption, and safety accidents. This greatly affects the stability and safety of the large-span flexible support system for photovoltaic panels.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a central column for a large-span flexible support for photovoltaic panels, comprising a fixed column, wherein a connecting mechanism is provided on the outer wall of the fixed column for connecting other fixed columns, and an anti-bending mechanism is provided on the top of the fixed column for increasing the anti-bending resistance of the fixed column. The anti-bending mechanism includes a crossbeam, the bottom of which is welded to the top of a fixed column. A mounting groove is provided on the right side of the crossbeam, and a stiffening plate is slidably connected inside the mounting groove. U-shaped rings are fixedly connected to the top left and right sides of the stiffening plate.

[0007] As a further description of the above technical solution: The fixed column is made of Q355B hollow round steel with a diameter of 217MM-221MM and a thickness of 6MM-10MM. Preferably, the diameter is 219MM and the thickness is 8MM.
[0008] As a further description of the above technical solution: The stiffening plate is a Q355B hollow square steel with a cross-section of 250mm x 150mm and a thickness of 6mm-10mm, preferably 8mm.
[0009] As a further description of the above technical solution: The mounting assembly includes a base plate, the bottom of which is welded to the bottom of a fixed column, and anchor bolts are threaded to the four corners of the top of the base plate.
[0010] As a further description of the above technical solution: The connecting cable assembly includes multiple fixing plates, which are respectively fixedly connected to the upper middle part of the front and rear sides of the fixed column. Semicircular rings are fixedly connected to the opposite sides of the multiple fixing plates.
[0011] As a further description of the above technical solution: Both connecting posts adopt a cross design, with the left post higher than the right post.
[0012] As a further description of the above technical solution: The anti-bending mechanism also includes multiple support plates, which are fixedly connected to the bottom of the outer wall of the fixed column, and all of the support plates adopt a ring design.
[0013] This utility model has the following beneficial effects: 1. In this utility model, when installing the anti-bending mechanism, the crossbeam is welded to the top of the fixed column, the stiffening rib is fixed at the connection between the two, the stiffening plate is slidably installed into the crossbeam mounting groove, and the U-shaped ring allows the main load-bearing cable to pass through to transmit tension; the fixed column is connected to the ground through the installation components, the windproof cable is connected to the connecting cable components, and the status of each component is checked during maintenance, which effectively improves the anti-bending resistance of the fixed column, ensures its installation stability and functional expandability, reduces swaying under wind force, ensures that the fixed column stably supports the photovoltaic bracket in complex environments, and improves the stability and safety of the bracket.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Reference Figures 1-4 The present invention provides an embodiment of a central column for a large-span flexible support for photovoltaic panels, comprising a fixed column 1, a connecting mechanism 2 provided on the outer wall of the fixed column 1 for connecting other fixed columns 1, and an anti-bending mechanism 3 provided on the top of the fixed column 1 for increasing the anti-bending resistance of the fixed column 1. The anti-bending mechanism 3 includes a crossbeam 31, the bottom of which is welded to the top of the fixed column 1. An installation groove 32 is provided on the right side of the crossbeam 31. A stiffening plate 33 is slidably connected inside the installation groove 32. U-shaped rings 34 are fixedly connected to the top of the stiffening plate 33 on both the left and right sides. Stiffening ribs 35 are fixedly connected to the top of the left and right sides of the outer wall of the fixed column 1. The top of the two stiffening ribs 35 are fixedly connected to the bottom of the crossbeam 31. An installation assembly 37 is provided at the bottom of the fixed column 1. A connecting cable assembly 38 is provided on the upper middle part of the front and rear sides of the fixed column 1. Specifically, when installing the bending resistance mechanism 3, the bottom of the crossbeam 31 is first welded to the top of the fixed column 1. Through the welding of the crossbeam 31 and the fixed column 1, the crossbeam 31 and the fixed column 1 form an integral structure, improving the structural strength of the top of the fixed column 1. Then, two stiffening ribs 35 are fixed to the top left and right sides of the outer wall of the fixed column 1, and the top of the stiffening ribs 35 is fixedly connected to the bottom of the crossbeam 31. Through the cooperation of the stiffening ribs 35 with the fixed column 1 and the crossbeam 31, the stability of the connection between the crossbeam 31 and the fixed column 1 is further enhanced, the external force borne by the crossbeam 31 is dispersed, and the deformation of this part due to the concentration of force is avoided, thus achieving the initial improvement of the bending resistance of the fixed column 1. The stiffening plate 33 is then slidably installed into the mounting groove 32 on the right side of the crossbeam 31. The installation position of the stiffening plate 33 is limited by the cooperation between the stiffening plate 33 and the mounting groove 32, ensuring that the stiffening plate 33 can stably act on the crossbeam 31. The U-shaped ring 34 at the top of the stiffening plate 33 allows the main load-bearing cable of the photovoltaic bracket to pass through. Through the cooperation between the U-shaped ring 34 and the main load-bearing cable, the tension of the main load-bearing cable is transferred to the stiffening plate 33, and then from the stiffening plate 33 to the crossbeam 31. Through the cooperation between the stiffening plate 33 and the crossbeam 31, the crossbeam 31's ability to withstand tension is enhanced, preventing the crossbeam 31 from bending under the action of the main load-bearing cable, and further improving the bending resistance of the fixed column 1. When the fixed column 1 needs to be installed on the ground, the mounting component 37 at the bottom of the fixed column 1 is connected to the ground. Through the cooperation of the mounting component 37, the fixed column 1 and the ground, the fixed column 1 is stably fixed on the ground, preventing the fixed column 1 from tilting or shifting during use, and providing basic support for the fixed column 1 to play its anti-bending role. When windproof cables need to be connected later, the windproof cables are connected to the cable assembly 38 on the upper middle part of the front and rear sides of the fixed column 1. Through the cooperation of the cable assembly 38, the fixed column 1, and the windproof cables, the tension of the windproof cables is transferred to the fixed column 1. The pulling effect of the windproof cables on the fixed column 1 reduces the swaying of the fixed column 1 under the action of wind, indirectly enhances the bending stability of the fixed column 1, and ensures that the fixed column 1 can stably support the photovoltaic bracket in complex environments. During maintenance, the welding status of the crossbeam 31 and the fixed column 1 can be checked to ensure that the welding is firm; the fixing status of the stiffening rib plate 35 to the fixed column 1 and the crossbeam 31 can be checked, and any loose connections can be repaired; the sliding fit status of the stiffening plate 33 and the mounting groove 32 can be checked, and impurities in the groove can be cleaned; the connection status of the U-shaped ring 34 and the stiffening plate 33 can be checked to ensure that the tension can be stably transmitted; the fixing status of the mounting component 37 to the ground can be checked, and any loose parts can be reinforced; the integrity of the cable assembly 38 can be checked to ensure that the windproof cable can be stably connected. This effectively improves the bending resistance of the fixed column 1, while ensuring the installation stability and functional expandability of the fixed column 1, providing reliable support for the large-span flexible support for photovoltaic panels.
[0018] Reference Figures 3-5 The connecting mechanism 2 includes two clamps 21. The inside of each clamp 21 is fixedly connected to the outer wall of the fixed column 1. A connecting column 22 is fixedly connected to the right side of each clamp 21. A clamp 23 is fixedly connected to the right side of each connecting column 22. Specifically, during the connection operation, the two clamps 21 are first fitted onto the outer wall of the fixed column 1. Through the cooperation between the clamps 21 and the fixed column 1, the clamps 21 are tightly fitted to the surface of the fixed column 1, initially defining the position of the clamps 21 on the fixed column 1. Then, the clamps 21 are fixed to ensure that there is no relative sliding between the clamps 21 and the fixed column 1. The fixed connection between the clamps 21 and the fixed column 1 provides a stable foundation for the subsequent connection of components. After clamp 21 is fixed, the connecting post 22 on its right side remains fixed along with clamp 21. Since the right side of the connecting post 22 is fixedly connected to clamp 23, the clamp 23 is rigidly connected to clamp 21 through the cooperation of the connecting post 22 with clamp 21 and clamp 23, so that clamp 23 and clamp 1 are in a stable positional relationship. The fixed column 1 to be connected is placed inside the clamp 23. Through the cooperation between the clamp 23 and the external component, the clamp 23 is tightly attached to the surface of the external component. The clamp 23 is then fixed to restrict the relative movement between the external component and the clamp 23. Through the synergistic action of the clamp 1 21, the connecting column 22, and the clamp 23, a stable connection between the fixed column 1 and another fixed column 1 is achieved, preventing the connection from loosening and ensuring the assembly stability of the overall structure.
[0019] Reference Figures 1-3 The fixed column 1 is made of Q355B hollow round steel with a diameter of 217MM-221MM and a thickness of 6MM-10MM. The stiffening plate 33 is made of Q355B hollow square steel with a cross section of 250MM*150MM and a thickness of 6MM-10MM. The mounting component 37 includes a base plate 371, the bottom of which is welded to the bottom of the fixed column 1. Anchor bolts 372 are threaded to the four corners of the top of the base plate 371. Specifically, the fixed column 1 is made of Q355B hollow round steel. By combining the characteristics of this material with a specific diameter and thickness, the structural strength of the fixed column 1 is ensured while reducing the amount of material used, thus achieving structural lightweighting. The stiffening plate 33 is made of Q355B hollow square steel. Combined with specific cross-sectional dimensions and thickness, it enhances the load-bearing capacity of the crossbeam 31. Through the cooperation between the stiffening plate 33 and the crossbeam 31, the bending resistance of the bending mechanism 3 is further improved, ensuring that the fixed column 1 is not easily deformed when bearing the load of the photovoltaic bracket. When the fixed column 1 needs to be installed on the ground using the mounting component 37, first align the base plate 371 at the bottom of the fixed column 1 with the preset installation position on the ground; ensure that the base plate 371 and the fixed column 1 are firmly connected by welding, providing a stable support foundation for the fixed column 1; then insert the anchor bolts 372 through the threaded holes at the four corners of the top of the base plate 371, so that the bottom of the anchor bolts 372 contacts the preset installation structure inside the ground; Rotate the anchor bolt 372, and the anchor bolt 372 moves downward along the threaded hole of the base plate 371 until the anchor bolt 372 is completely fixed to the pre-installed structure on the ground; through the cooperation of the anchor bolt 372 and the base plate 371, the base plate 371 is tightly pressed onto the ground, restricting the horizontal and vertical movement of the base plate 371; through the synergistic action of the four anchor bolts 372, the base plate 371 is fixed from the four corners, preventing uneven force on the base plate 371 from causing the fixed column 1 to tilt; through the cooperation of the installation component 37 and the ground, a stable connection between the fixed column 1 and the ground is achieved, ensuring that the fixed column 1 remains stable when bearing the load of the photovoltaic bracket and the forces of the external environment; After installation, the Q355B hollow round steel structure of the fixed column 1, in conjunction with the installation component 37, transfers the load borne by the fixed column 1 to the ground; the Q355B hollow square steel structure of the stiffening plate 33, in conjunction with the crossbeam 31 and stiffening rib plate 35, further disperses the load, and through the synergistic effect of the bending resistance mechanism 3 and the installation component 37, enhances the overturning resistance and structural stability of the entire central column; During maintenance, the welding status of the base plate 371 and the fixed column 1 can be checked to ensure that there are no cracks in the welded parts; the thread fit between the anchor bolt 372 and the base plate 371 can be checked, and any loose anchor bolts 372 can be tightened; the structural integrity of the fixed column 1 and the stiffening plate 33 can be checked to ensure that there is no obvious deformation. This achieves the stable installation of the fixed column 1 on the ground and ensures the structural performance of the middle column, providing support for the stable operation of the large-span flexible support for photovoltaic panels.
[0020] Reference Figures 1-5 The cable assembly 38 includes multiple fixing plates 381, which are fixedly connected to the upper middle part of the front and rear sides of the fixed column 1. Semicircular rings 382 are fixedly connected to the opposite sides of the multiple fixing plates 381. The two connecting columns 22 adopt a cross design and are arranged with the left higher than the right. The bending resistance mechanism 3 also includes multiple support plates 36, which are fixedly connected to the bottom of the outer wall of the fixed column 1. The multiple support plates 36 adopt a ring design. Specifically, when installing the cable assembly 38, multiple fixing plates 381 are first fixed sequentially at preset intervals on the upper middle part of the front and rear sides of the fixed column 1. Through the cooperation between the fixing plates 381 and the fixed column 1, a stable mounting carrier is provided for the semi-circular ring 382. Then, the semi-circular ring 382 is fixed on the side of each fixing plate 381 that is far away from each other. In subsequent use, the external cable can be connected to the semi-circular ring 382. Through the cooperation between the semi-circular ring 382, the fixing plate 381, and the fixed column 1, the tension of the external cable is transmitted to the fixed column 1, forming a lateral traction on the fixed column 1, thereby enhancing the anti-tipping ability of the fixed column 1 and preventing the fixed column 1 from tilting under the action of lateral force. When the connecting column 22 is assembled with clamp 1 21 and clamp 23, the two connecting columns 22 adopt a cross design and are in a state of left higher than right. Through the cooperation of the connecting column 22 with clamp 1 21 and clamp 23, an asymmetrical inclined support structure is formed between clamp 23 and fixed column 1. When clamp 23 is subjected to external force, the cross connecting column 22 can disperse the external force to clamp 1 21 and fixed column 1, avoiding the deformation or breakage caused by the force concentration on one side of the connecting column 22. Through the structural design of the connecting column 22 and the cooperation of the clamp assembly, the connection stability between the connecting mechanism 2 and the fixed column 1 is improved. When installing the support plate 36 of the anti-bending mechanism 3, multiple annular support plates 36 are sequentially fixed to the bottom of the outer wall of the fixed column 1 along the height direction. Through the cooperation between the support plate 36 and the fixed column 1, the contact range between the bottom of the fixed column 1 and the mounting surface is increased. At the same time, the annular structure allows the pressure on the bottom of the fixed column 1 to be evenly transmitted to the support plate 36, and then distributed to the mounting surface by the support plate 36, avoiding excessive local stress on the bottom of the fixed column 1. Through the annular design of the support plate 36 and its cooperation with the fixed column 1, the effect of enhancing the anti-bending performance of the bottom of the fixed column 1 is achieved, preventing the fixed column 1 from bending due to uneven stress at the bottom. During equipment operation, the cable assembly 38 provides lateral protection from the upper part of the fixed column 1, the connecting column 22 enhances connection stability from the middle, and the support plate 36 strengthens the bending resistance from the bottom. During maintenance, check whether the connection between the fixed plate 381 and the fixed column 1 is firm and ensure that the semi-circular ring 382 is not loose; check whether the cross structure of the connecting column 22 is intact and without deformation; check the fixing status of the support plate 36 and the fixed column 1 to ensure that the ring structure is not damaged. This achieves multi-directional structural reinforcement of the fixed column 1, providing a guarantee for the overall operation of the equipment.
[0021] Working principle: First, the bottom of the crossbeam 31 is welded to the top of the fixed column 1. Through this welding, the crossbeam 31 and the fixed column 1 form an integral structure, enhancing the structural strength of the top of the fixed column 1 and laying the foundation for subsequent load transfer. Second, two stiffening ribs 35 are fixed to the top left and right sides of the outer wall of the fixed column 1, ensuring that the top of the stiffening ribs 35 is fixedly connected to the bottom of the crossbeam 31. Through the cooperation of the stiffening ribs 35 with the fixed column 1 and the crossbeam 31, the stability of the connection between the crossbeam 31 and the fixed column 1 is further enhanced, dispersing the external force borne by the crossbeam 31 and preventing deformation due to concentrated stress, thus initially improving the bending resistance of the fixed column 1. Third, the stiffening plate 33 is slidably installed into the mounting groove 32 on the right side of the crossbeam 31. Through the cooperation of the stiffening plate 33 and the mounting groove 32, the installation position of the stiffening plate 33 is limited, ensuring that the stiffening plate 33 can stably act on the crossbeam 31; the top of the stiffening plate 33... The U-shaped ring 34 allows the main load-bearing cable of the photovoltaic bracket to pass through. In subsequent use, the U-shaped ring 34, in conjunction with the main load-bearing cable, transfers the tension of the main load-bearing cable to the stiffening plate 33, and then from the stiffening plate 33 to the crossbeam 31. The stiffening plate 33, in conjunction with the crossbeam 31, enhances the crossbeam 31's ability to withstand tension, preventing the crossbeam 31 from bending under the action of the main load-bearing cable, and further improving the bending resistance of the fixed column 1. In the fourth step, multiple ring-shaped support plates 36 are sequentially fixed to the bottom of the outer wall of the fixed column 1 along its height direction. The support plates 36, in conjunction with the fixed column 1, increase the contact range between the bottom of the fixed column 1 and the mounting surface. At the same time, the ring structure allows the pressure on the bottom of the fixed column 1 to be evenly transferred to the support plates 36, and then distributed to the mounting surface by the support plates 36, avoiding excessive local stress on the bottom of the fixed column 1, thereby enhancing the bending resistance of the bottom of the fixed column 1 and preventing the fixed column 1 from bending due to uneven stress on the bottom. First, two clamps 21 are fitted onto the outer wall of the fixed column 1. Through the cooperation between clamps 21 and the fixed column 1, clamps 21 are tightly fitted to the surface of the fixed column 1, initially defining the position of clamps 21 on the fixed column 1. Then, clamps 21 are fixed to ensure there is no relative sliding between clamps 21 and the fixed column 1. This fixed connection between clamps 21 and the fixed column 1 provides a stable foundation for subsequent component connections. After clamps 21 are fixed, the connecting column 22 on its right side remains fixed along with clamps 21. Since the right side of connecting column 22 is fixedly connected to clamp 23, and the two connecting columns 22 are designed in a cross pattern with the left side higher than the right, the connection between the connecting column 22 and the clamp... The cooperation of clamp 21 and clamp 23 rigidly connects clamp 23 to clamp 21, forming an asymmetrical inclined support structure between clamp 23 and fixed column 1. When it is necessary to connect another fixed column 1, the fixed column 1 to be connected is placed inside clamp 23. Through the cooperation between clamp 23 and the fixed column 1 to be connected, clamp 23 is tightly attached to its surface. Then clamp 23 is fixed to restrict the relative movement between the fixed column 1 to be connected and clamp 23. Through the synergistic effect of clamp 21, connecting column 22 and clamp 23, a stable connection of two fixed columns 1 is achieved, avoiding loosening of the connection parts and ensuring the assembly stability of the overall structure. Multiple fixing plates 381 are sequentially fixed at preset intervals on the upper middle part of the front and rear sides of the fixed column 1. The cooperation between the fixing plates 381 and the fixed column 1 provides a stable mounting carrier for the semi-circular ring 382. The semi-circular ring 382 is then fixed on the side of each fixing plate 381 that is far away from each other. When connecting the windproof cable, the windproof cable is connected to the semi-circular ring 382. Through the cooperation between the semi-circular ring 382, the fixing plate 381, and the fixed column 1, the tension of the windproof cable is transmitted to the fixed column 1. The traction of the windproof cable on the fixed column 1 reduces the swaying of the fixed column 1 under the action of wind, indirectly enhancing the bending stability of the fixed column 1 and ensuring that the fixed column 1 can stably support the photovoltaic bracket in complex environments. The connection to the ground is achieved by fixing the mounting assembly 37 at the bottom of the column 1. First, align the base plate 371 at the bottom of the column 1 with the preset installation position on the ground. Welding the base plate 371 to the column 1 ensures a secure connection, providing a stable support foundation for the column 1. Second, insert the anchor bolts 372 through the threaded holes at the four corners of the top of the base plate 371, making the bottom of the anchor bolts 372 contact the preset installation structure inside the ground. Third, rotate the anchor bolts 372 along the threaded holes of the base plate 371. The anchor bolts 372 are moved downwards until they are completely fixed to the pre-installed structure on the ground. Through the cooperation of the anchor bolts 372 and the base plate 371, the base plate 371 is tightly pressed onto the ground, restricting the horizontal and vertical movement of the base plate 371. Through the synergistic action of the four anchor bolts 372, the base plate 371 is fixed from the four corners, preventing uneven force on the base plate 371 from causing the fixed column 1 to tilt. This achieves a stable connection between the fixed column 1 and the ground, preventing the fixed column 1 from tilting or shifting during use, and providing basic support for the fixed column 1 to play its anti-bending role. In the entire structure, the fixed column 1 is made of Q355B hollow round steel. Through the combination of the material properties and specific diameter and thickness, the material usage is reduced while ensuring the structural strength, thus achieving structural lightweighting. The stiffening plate 33 is made of Q355B hollow square steel. Combined with specific cross-sectional dimensions and thickness, it enhances the load-bearing capacity of the crossbeam 31. Through the cooperation between the stiffening plate 33 and the crossbeam 31, the bending resistance of the bending mechanism 3 is further improved, ensuring that the fixed column 1 is not easily deformed when bearing the load of the photovoltaic bracket. After installation, the cooperation between the Q355B hollow round steel structure of the fixed column 1 and the installation component 37 transfers the load borne by the fixed column 1 to the ground. The cooperation between the Q355B hollow square steel structure of the stiffening plate 33, the crossbeam 31, and the stiffening rib plate 35 further disperses the load. Through the synergistic effect of the bending resistance mechanism 3 and the installation component 37, the overturning resistance and structural stability of the entire fixed column 1 are improved. When maintaining the anti-bending mechanism 3, check the welding status of the crossbeam 31 and the fixed column 1 to ensure the welding is firm; check the fixing status of the stiffening rib plate 35 to the fixed column 1 and the crossbeam 31, and repair any loose connections; check the sliding fit status of the stiffening plate 33 and the mounting groove 32, and clean any impurities in the groove; check the connection status of the U-shaped ring 34 and the stiffening plate 33 to ensure stable transmission of tension; check the fixing status of the support plate 36 and the fixed column 1 to ensure the annular structure is undamaged. When maintaining the connecting mechanism 2, check the fixing status of the clamp 21 and the fixed column 1 to ensure there is no relative sliding; check whether the cross structure of the connecting column 22 is intact and free from deformation; check... Check the fixing status of clamp 23 and the fixed column 1 to be connected to prevent loosening. When maintaining the connecting cable assembly 38, check whether the connection between the fixing plate 381 and the fixed column 1 is firm and ensure that the semi-circular ring 382 is not loose.
