[0059] The core of this application is to disclose a bridge frame and photovoltaic equipment to meet the gap connection between photovoltaic panels and reduce the overall structural cost and assembly cost.

[0060] In order to enable those skilled in the art to better understand the present invention, the embodiments of the present invention are described below with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention contents described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions to the inventions described in the claims.

[0061] like Figure 1 As shown, the present disclosure provides a method for installing a flexible tracking photovoltaic bracket for an exhibition, so that each component can be transported to the exhibition site by split transportation, and the installation of the flexible tracking photovoltaic bracket can be completed on site, so as to ensure that the installation structure of the flexible tracking photovoltaic bracket meets the display needs according to the actual site conditions. Specifically, Figure 1 and Figure 8 As shown, the installation method includes at least the following steps:

[0062] S01: Install the bearing base: arrange at least three bearing beams 110 in parallel at the same interval, and adjacent bearing beams 110 are connected by multiple connecting beams 120, and the connecting beams 120 are arranged perpendicular to the bearing beams 110; fix the docking area between the bearing beams 110 and the connecting beams 120, the bearing beam 110 located in the middle and the connecting beams 120 on both sides thereof form a cross-shaped first intersection area 140, and the bearing beams 110 located on both sides and the connecting beams 120 on one side thereof form a T-shaped second intersection area 150.

[0063] It should be noted that, in step S01, the purpose of providing at least three load-bearing beams 110 is to provide sufficient installation space. Figure 1 , Figure 2 and Figure 3 As shown, the column assembly 20 is supported by the load beam 110 in the middle, and the load beams 110 on both sides provide space for the installation of the inclined cable 320, so that the inclined cable 320 can support the active area on the column assembly 20 from both sides. At the same time, according to the actual situation of the site, more load beams 110 can be arranged to provide a larger setting space for other structures of the flexible tracking photovoltaic support.

[0064] In addition, the base 10 structure is formed by setting a load-bearing beam 110 and connecting beams 120 perpendicular thereto. The base 10 structure can be partially hollowed out and partially supported, and a profile structure can be set in the necessary area to reduce the total weight of the base 10 and improve the convenience of assembly of the flexible tracking photovoltaic bracket. Figure 1 As shown, the structure of the load-bearing beams 110 arranged at intervals can form a cross-shaped first intersection area 140 and a T-shaped second intersection area 150 after the connecting beam 120 is fixed, and for the base 10 structure with three load-bearing beams 110, it can form a first intersection area 140 and two second intersection areas 150 with the connecting beam 120 in the arrangement direction of the load-bearing beams 110, and for the base 10 structure with more load-bearing beams 110, only the load-bearing beams 110 at the two side positions form two second intersection areas 150, and the intersection of the inner load-bearing beam 110 and the connecting beam 120 forms the first intersection area 140. Due to the intersection structure, the first intersection area 140 can be used to bear structures with higher strength, such as the column assembly 20, and the second intersection area 150 can be used for structures with lower strength requirements, such as the fixing point of the inclined cable 320, so as to ensure the rationality of the structural arrangement on the base 10.

[0065] In a specific embodiment of the present disclosure, the load-bearing beam 110 in step S01 is arranged in sections and spliced ​​and fixed. Specifically, Fig.16 and Fig.17 As shown, a single load-bearing beam 110 is arranged in sections, which includes at least two load-bearing parts 1110, and the two load-bearing parts 1110 are fixed by a splicing node 1120. The section design allows the load-bearing beam 110 to be flexibly adjusted according to the specific size and space conditions of the exhibition site, which is convenient for quickly building the base 10 at different sites. At the same time, the section splicing method is also convenient for transportation, especially when the exhibition site is relatively scattered or the space is limited, the load-bearing beam 110 can be transported to the site in sections and then quickly spliced, which greatly improves the installation efficiency. It should be noted that the load-bearing beam 110 is an I-beam structure, such as Fig.17 As shown, the splicing node 1120 includes three groups of gussets 1130, each group of gussets 1130 is arranged in pairs, and after the two bearing parts 1110 are butt-jointed, the three groups of gussets 1130 are buckled and arranged on the upper surface, lower surface and middle wall surface of the butt-jointed area of ​​the bearing parts 1110, and each group of gussets 1130 is fixed by at least 8 bolts, so that after the plates are buckled, the two bearing parts 1110 are fixed from the upper surface, lower surface and middle wall surface of the bearing parts 1110 respectively; the multi-point connection method ensures the firmness and reliability of the splicing, and can effectively transmit the various forces to which the bearing beam 110 is subjected during use. For example, in a specific embodiment of the present disclosure, the cross-sectional height and width of the bearing beam 110 of the I-beam structure are both 200mm, and the thickness of the two side wing plates is 12mm, and the thickness of the web between the two wing plates is 8mm; and the splicing node 1120 used to connect the adjacent bearing parts 1110 includes 24 bolts with a specification of not less than M16×60 for fixing. At the same time, the cross-sectional height and width of the connecting beam 120 are the same as the specifications of the load-bearing beam 110, and the thickness of the two side wing plates is 12 mm, and the thickness of the web between the two wing plates is 8 mm. Each connecting beam 120 is arranged perpendicular to the load-bearing beam 110, and each connecting beam 120 is fixed at both ends with bolts of a specification not less than M16×60, and at least 2 bolts are used at a single end. It should be noted that the above-mentioned bolts are provided with two flat washers and one elastic washer on the outer periphery when they are fixed.

[0066] S02: Install the column assembly, install the column head node 240 on the top of the support column 210, and fix the bottom of the support column 210 to the first intersection area 140 on the base 10. The two column assemblies 20 are arranged at intervals on the same load-bearing beam 110; the reducer and the connecting ear plate 2420 are fixed on the column head node 240, and the adjusting beam 230 is assembled in the rotating area of ​​the reducer.

[0067] It should be noted that, in step S02, Figure 1 and Fig. 9As shown, the column head node 240 is the area in the column assembly 20 for carrying the reducer and connecting the ear plate 2420. It is first stably fixed on the support column 210, and then the support column 210 is assembled on the base 10; at the same time, the bottom of the support column 210 is fixed to the first intersection area 140, which can ensure the bottom support stability of the column assembly 20, thereby improving its bearing effect on the main cable 310 and the photovoltaic assembly 60. In addition, the two column assemblies 20 are arranged at intervals on the same load-bearing beam 110, which can make the main cable 310 form an arrangement structure parallel to the load-bearing beam 110, and the axial force on the main cable 310 can be smoothly borne by the load-bearing beam 110, thereby improving the structural stability of the flexible tracking photovoltaic bracket.

[0068] S03: Install the inclined cables. Two inclined cables 320 are symmetrically arranged on both sides of a single column assembly 20. The first end of each inclined cable 320 is fixed to the second intersection area 150 on the base 10, and the second end is fixed to the connecting ear plate 2420 on the column head node 240.

[0069] S04: Install the main cables. The two main cables 310 are arranged in parallel. A single main cable 310 maintains a preset tension force and both ends of the main cable 310 are fixed to the adjustment beams 230 of the two column assemblies 20 .

[0070] In step S03 and step S04, based on the column assembly 20 fixed on the base 10, the main cable 310 is fixed on the adjusting beam 230, and the inclined cable 320 is fixed on the column head node 240. The bottom of the inclined cable 320 is connected to the second intersection area 150, so as to maintain the stable structure of the inclined cable 320 through the cooperation of the load-bearing beam 110 and the connecting beam 120 on the base 10, thereby achieving the tensioning effect on the column head node 240 and the main cable 310.

[0071] In some embodiments of the present disclosure, Fig. 9As shown, a fixed node 2320 is welded and fixed on the adjustment beam 230, and a first reinforcing plate 2330 can be set on the back of the fixed node 2320 to achieve a stable connection effect on the adjustment beam 230. The main cable 310 passes through the fixed node 2320 and is fixed by a special cable clamp or bolt to maintain the integrated structure of the adjustment beam 230 and improve the structural stability of the adjustment beam 230. On this basis, by adjusting the rotating part 220 to drive the adjustment beam 230 to rotate, the adjustment beam 230 can drive at least two main cables 310 to rotate, and realize the rotation adjustment of the photovoltaic assembly 60, so that the photovoltaic assembly 60 can track the light. The inclined cable 320 is used to enhance the structural stability of the column assembly 20. Specifically, the first end of the inclined cable 320 is fixed to the base 10, and the second end is fixed to the area of ​​the column assembly 20 close to the rotating part 220, so as to effectively improve the lateral force resistance of the column assembly 20 and ensure the structural stability of the flexible tracking photovoltaic bracket at the exhibition site.

[0072] It should be noted that in step S04, after the two main cables 310 are assembled on the adjusting beam 230, a tensioning force of not less than 20 KN needs to be applied to both ends thereof. After the main cables 310 are tightened, the main cables 310 are fixed on the adjusting beam 230. The tensioned main cables 310 can maintain a stressed state and maintain their setting state after carrying the photovoltaic components 60. At the same time, after the tensioned main cables 310 are fixed on the adjusting beam 230, the excess areas at both ends are cut off to maintain the beauty of the flexible tracking photovoltaic bracket during the exhibition.

[0073] At the same time, in order to directly monitor the angle change of the adjustment beam 230, such as Fig.13 As shown, the embodiment of the present disclosure also includes a tilt sensor 2310 arranged on the adjustment beam 230. The tilt sensor 2310 can be assembled in step S02. It should be noted that the adjustment beam 230 is the basis for supporting the main cable 310 and other structures in the photovoltaic bracket, and it is also the basis for realizing the angle adjustment of the photovoltaic component 60. By installing the tilt sensor 2310 on the adjustment beam 230, the actual angle of the photovoltaic component 60 can be monitored in real time, and the data can be fed back to the control system. The control system can automatically adjust the rotation angle of the reducer according to the feedback data of the tilt sensor 2310, thereby realizing the flexible tracking function of the photovoltaic component 60, so that the photovoltaic bracket can always maintain the best operating state during the exhibition, and realize the display of the flexible tracking photovoltaic bracket in full operation state at the exhibition.

[0074] For some flexible tracking photovoltaic brackets with wind-resistant frame 40 structure, the installation method provided by the present disclosure also includes the following steps:

[0075] S05: Install wind-resistant frame.

[0076] It should be noted here that, for step S05, the stabilizing cable 410 in the wind-resistant frame 40 can be tightened and fixed without being tensioned, so as to achieve the display effect and reduce the difficulty of assembly; at the same time, the stabilizing cable 410 can also be tensioned like the main cable 310 to maintain its stabilizing effect on the wind-resistant frame 40. In addition, the installation of the wind-resistant frame 40 and the stabilizing cable 410 can be carried out after the installation of the main cable 310 is completed, or it can be carried out simultaneously with the main cable 310.

[0077] In some embodiments of the present disclosure, the installation of the wind-resistant frame 40 is performed after the main cable 310 is assembled and tensioned. Specifically, step S05 is performed after step S04, and step S05 is specifically: installing the wind-resistant frame 40, pre-fixing the wind-resistant frame 40 on the main cable 310 at the middle position of the two column assemblies 20, so that the wind-resistant frame 40 can be slidably adjusted along the main cable 310 while maintaining contact with the main cable 310. This process can be achieved by the bolts of the U-shaped structure. At the same time, the bottom of the wind-resistant frame 40 can also be movably penetrated by the bolts of the U-shaped structure. Two stabilizing cables 410 are also provided.

[0078] During the assembly process, the wind-resistant frame 40 and the main cable 310 are first fixedly connected so that the wind-resistant frame 40 is stably located at the preset position, and then the two ends of the stabilizing cable 410 are tightened so that the main cable 310 is in an upward arch state. After the main cable 310 is kept in the upward arch state, the two ends of the two stabilizing cables 410 are fixed, and then the bolts of the U-shaped structure between the wind-resistant frame 40 and the stabilizing cable 410 are locked to complete the assembly of the wind-resistant frame 40. The above-mentioned installation method can make the main cable 310 and the wind-resistant cable on one side form a spindle-like structure with small cross-sections at both ends and a large cross-section in the middle, so that the main cable 310 forms a stable support structure in its action area to improve the wind resistance performance.

[0079] At the same time, during the assembly process, the operator can also tighten the two ends of the stabilizing cable 410 after the wind-resistant frame 40 is pre-fixed on the main cable, so as to act on the main cable 310 through the wind-resistant frame 40, so that the main cable 310 is in an upward arch state, and then fix the two end positions of the stabilizing cable 410, and then perform a fixed connection operation on the wind-resistant frame 40 and the main cable 310.

[0080] In other embodiments of the present disclosure, in order to maintain the stabilizing effect of the stabilizing cable 410 on the wind-resistant frame 40 and the main cable 310, the stabilizing cable 410 needs to be tensioned like the main cable 310. On this basis, step S05 needs to tension the stabilizing cable 410. It should be noted that the tensioning of the stabilizing cable 410 can be performed synchronously or stepwise with the main cable 310. Specifically, in one embodiment of the present disclosure, after the tensioning of the main cable 310 is completed, the wind-resistant frame 40 is pre-fixed on the main cable 310 at the midpoint of the two column assemblies 20, and the stabilizing cable 410 is pre-movably inserted on the wind-resistant frame 40. The stabilizing cable 410 is tensioned at both ends of the stabilizing cable 410, and the wind-resistant frame 40 and the main cable 310 are fixed at the same time; after the tensioning of the stabilizing cable 410 is completed, the stabilizing cable 410 and the wind-resistant frame 40 are fixed, and the two ends of the stabilizing cable 410 are fixed.

[0081] At the same time, step S05 can also be executed before the main cable 310 is tensioned. Specifically, after the main cable 310 is installed, the wind-resistant frame 40 is pre-fixed on the main cable 310 at the midpoint of the two column assemblies 20, and the stabilizing cable 410 is pre-pierced on the wind-resistant frame 40. The main cable 310 and the stabilizing cable 410 are tensioned at the same time to tighten the wind-resistant frame 40. This process is carried out synchronously for the tensioning of the main cable 310 and the stabilizing cable 410, and can coordinate the tension between the two to avoid the tensioning process of the stabilizing cable 410 affecting the force of the main cable 310 when the main cable 310 is tensioned first and the stabilizing cable 410 is tensioned later. After the tensioning of the main cable 310 and the stabilizing cable 410 is completed, the connection points between the wind-resistant frame 40 and the main cable 310 and the stabilizing cable 410 are fixed, and then the two ends of the stabilizing cable 410 are fixed. It should be noted that the above processes can realize the assembly of the wind-resistant frame 40 and the stabilizing cable 410 on the main cable, and the operator can select a suitable installation method according to the exhibition environment and the exhibition effect.

[0082] In order to further optimize the above technical solution, in some embodiments of the present disclosure, such as Figure 1 , Figure 4 and Figure 5As shown, a single main cable 310 has two first connection points 420 with the wind-resistant frame 40 in the length direction thereof, and the stabilizing cable 410 has a second connection point 430 with the wind-resistant frame 40 in the length direction thereof, and for a single set of main cables 310 and stabilizing cables 410, the two first connection points 420 and the one second connection point 430 form an isosceles triangle with the second connection point 430 as the vertex, so as to enhance the supporting effect of the stabilizing cable 410 on the main cables 310. On this basis, the wind-resistant frame 40 further includes an oblique web bar 440 connecting the single set of first connection points 420 and the second connection point 430, that is, for the main cables 310 and the stabilizing cables 410 on one side, the two are connected by two oblique web bars 440, so as to enhance the wind-resistant effect. Furthermore, a stabilizing rod 450 can be fixedly arranged between the two diagonal webs 440. Preferably, the stabilizing rod 450 is arranged parallel to the main cable 310, and the stabilizing rod 450 is connected to the midpoint of each diagonal web 440, so that the diagonal webs 440 on both sides maintain a stable structural foundation, thereby improving the rigidity and stability of the wind-resistant frame 40, and effectively resisting the lateral thrust generated by the wind on the photovoltaic bracket.

[0083] It should be noted that the two diagonal braces 440 can be integrally formed, or pre-welded and fixed into an integral structure by welding, and then assembled on the wind-resistant frame 40; at the same time, the two diagonal braces 440 can also be two independently arranged rods, which are independently assembled on the wind-resistant frame 40 by bolt connection.

[0084] Furthermore, in the installation method provided by the present disclosure, step S03 specifically includes:

[0085] S301: Assemble the first end node. The first end of the inclined cable 320 is assembled with a connecting seat 3230. The disc structure at the bottom of the connecting seat 3230 is fixed to the base 10 by bolts. The connecting seat 3230 includes a connecting portion for the cable body end of the inclined cable 320 to be inserted and fixed. A U-shaped bolt 3240 is also sleeved on the outer periphery of the connecting portion. The U-shaped bolt 3240 and the non-end area of ​​the cable body of the inclined cable 320 are connected to form an integrated structure through a fixing block.

[0086] S302: Assemble the second end node. The second end of the inclined cable 320 is assembled with the inclined cylinder 3210. The inclined cylinder 3210 is provided with a through hole. The inclined cylinder 3210 is inserted into the connecting ear plate 2420 and fixed to the connecting ear plate 2420 through the connecting pin 3220. After the two ends of the inclined cable 320 are assembled with the base 10 and the connecting ear plate 2420 respectively, the inclined cable 320 is tightened by adjusting the nut.

[0087] It should be noted that in step S301, the connection structure of the inclined cable 320 is an important component to ensure the overall stability of the photovoltaic support, especially in the complex environmental conditions that may occur at the exhibition site. Among them, the connecting seat 3230 is a component that connects the inclined cable 320 and the base 10. Its main function is to effectively transfer the tension of the inclined cable 320 to the base 10; the connecting seat 3230 can be fixed to the base 10 by welding or bolting to ensure that it can remain stable when subjected to the tension of the inclined cable 320. Bolt connection is preferably used for easy disassembly and assembly. Fig.11 and Fig.14 As shown, the end of the cable body of the inclined cable 320 is inserted into the connecting seat 3230 and fixed. This insertion connection method can ensure the tight connection between the inclined cable 320 and the connecting seat 3230, and avoid the connection loosening due to external force. The U-shaped bolt 3240 is used to fix the cable body and the connecting seat 3230 of the inclined cable 320. Specifically, the U-shaped bolt 3240 is tightened by a nut, and the tightening force of the bolt can be adjusted according to actual needs to ensure that the inclined cable 320 always maintains appropriate tension during the exhibition; the bottom of the U-shaped bolt 3240 is sleeved on the connecting seat 3230, and the other end of the U-shaped bolt 3240 is fixed to the non-end area of ​​the cable body of the inclined cable 320 through a locking block, so as to ensure the firm connection between the inclined cable 320 and the connecting seat 3230.

[0088] In step S302, if Fig.12 As shown, the inclined cylinder 3210 is usually provided with a mounting groove for the bending area of ​​the connecting ear plate 2420 to be embedded and set. At the same time, the inclined cylinder 3210 is provided with a through hole and is fixed to the connecting hole 24210 of the connecting ear plate 2420 by a connecting pin 3220, so as to ensure a firm connection between the inclined cable 320 and the column node 240, and can also directly transmit the tensioning force of the inclined cable 320 to the column node 240 through the connecting ear plate 2420, thereby realizing an auxiliary tensioning effect on the main cable 310.

[0089] In addition, it should be noted that Figure 8 As shown, after step S05 is completed, the following steps are also included:

[0090] S06: Install the photovoltaic panel, and install the aluminum alloy connector 610 on the photovoltaic panel. The spacing between the two aluminum alloy connectors 610 on the same side of the photovoltaic panel is the same as the spacing between the two main cables 310. The aluminum alloy connector 610 is fixed to the main cable 310 by a clamp 620 with bolts.

[0091] S07: Install the operation and maintenance pole. The bottom of the operation and maintenance pole 50 is fixed to the load-bearing beam 110 by at least four bolts, and the operation and maintenance pole 50 and the column assembly 20 are arranged on the same load-bearing beam 110 .

[0092] It should be noted that if Figure 6 and Figure 7 As shown, the photovoltaic panel is connected to the main cable 310 through an aluminum alloy connector 610 and a clamp 620, which is similar to the currently commonly used photovoltaic panel connection structure and will not be described here. The operation and maintenance pole 50 is used to install and support the operation and maintenance equipment. The operation and maintenance pole 50 is fixedly arranged on the base 10, so that the operation and maintenance pole 50 can use the structural strength of the base 10 to ensure its stability during the exhibition. At the same time, the height and position of the operation and maintenance pole 50 can be optimized according to the layout and operation and maintenance requirements of the photovoltaic module 60 to ensure that the operation and maintenance equipment can be easily installed and operated. The bottom of the operation and maintenance pole 50 can be bolted to adjust its installation position on the base 10 according to actual needs. In addition, a support rod or a support platform is fixedly arranged on the operation and maintenance pole 50 to provide a stable installation platform for the operation and maintenance equipment. The relevant operation and maintenance equipment may include monitoring cameras, sensors, controllers, etc., for real-time monitoring of the operating status and environmental parameters of the photovoltaic module 60. This structure not only improves the operational stability of the photovoltaic system, but also provides an efficient and reliable photovoltaic bracket design solution for the exhibition site, achieving a more comprehensive display of the flexible tracking photovoltaic bracket provided by the present disclosure.

[0093] Furthermore, in the installation method provided by the present disclosure, the column head node 240 in the column assembly 20 is a connection structure that connects the support column 210 and the rotating part 220. The column head node 240 can be assembled separately with the support column 210, and the reducer is arranged at the column head node 240, and the adjustment beam 230 is fixedly arranged in the rotating area of ​​the reducer; through the rotation of the reducer, the adjustment beam 230 can be driven to rotate, and then the main cable 310 and the photovoltaic assembly 60 can be driven to adjust the angle, thereby realizing the flexible tracking function. In order to further optimize the above technical solution, such as Fig. 9 , Fig.10 and Fig.13As shown, the column head node 240 specifically includes a connecting plate 2410 and two connecting ear plates 2420, wherein the connecting plate 2410 is fixed to the support column 210 by pre-embedded setting or bolt connection, thereby ensuring the integrity and stability between the column head node 240 and the support column 210. It should be noted that the support column 210 is mostly a concrete column, and the connecting plate 2410 can be pre-embedded or bolted to achieve a fixed setting on the top of the support column 210, while providing a stable setting plane for other structures on the column head node 240, so that other structures on the column head node 240 can be fixed by convenient welding operations. It should be noted that in some embodiments of the present disclosure, the reducer is a horizontal reducer, and it is fixed by at least four bolts distributed at the four vertices of the rectangle that are set through the adjustment beam 230 to ensure its integral structure with the adjustment beam 230, thereby maintaining its stability in the rotation drive process of the adjustment beam 230.

[0094] It needs to be further explained that if Fig.10 As shown, a third reinforcing plate 2440 is further arranged between the reducer and the adjusting beam 230 to improve the connection effect between the reducer and the adjusting beam 230; the third reinforcing plate 2440 has two edges respectively contacting the reducer and the adjusting beam 230 so as to be welded and fixed to the reducer and the adjusting beam 230 respectively; and in the present embodiment, a plurality of third reinforcing plates 2440 can be arranged at intervals in the length direction of the adjusting beam 230, and similarly, the third reinforcing plate 2440 can also be arranged on one side or both sides of the upper and lower sides of the adjusting beam 230. In addition, for the assembly of the third reinforcing plate 2440, it can be pre-welded to the reducer, and after the reducer and the adjusting beam 230 are connected, the third reinforcing plate 2440 and the adjusting beam 230 are welded; similarly, the third reinforcing plate 2440 can also be pre-welded to the adjusting beam 230, and after the adjusting beam 230 and the reducer are assembled in place, the third reinforcing plate 2440 and the reducer are welded; in addition, the third reinforcing plate 2440 can also be welded to the reducer and the adjusting beam 230 after the reducer and the adjusting beam 230 are assembled, according to the strength requirements.

[0095] The connecting ear plate 2420 provides necessary support and connection points for the installation of the inclined cable 320. Specifically, the connecting ear plate 2420 is a bending plate with an integrated structure, so that the connecting ear plate 2420 can meet the bending requirements while avoiding the influence of the welds of the splicing structure on its structural strength, so that the connecting ear plate 2420 has higher structural strength and stability; at the same time, in order to meet the fixation of the inclined cable 320, the connecting ear plate 2420 is provided with a connecting hole 24210 in its bending area, and the bending areas of the two connecting ear plates 2420 are arranged to expand toward both sides, that is, after the two connecting ear plates 2420 are fixed, their bending areas are arranged away from the center direction of the column head node 240. Correspondingly, the second end of the inclined cable 320 is provided with an inclined cylinder 3210, which is provided with a mounting groove for the bending area of ​​the connecting ear plate 2420 to be embedded and set, and the inclined cylinder 3210 is provided with a through hole, and is fixed to the connecting hole 24210 of the connecting ear plate 2420 through a connecting pin 3220. The above connection structure not only ensures a firm connection between the inclined cable 320 and the column node 240, but also can directly transmit the tensioning force of the inclined cable 320 to the column node 240 through the connecting ear plate 2420, thereby realizing an auxiliary tensioning effect on the main cable 310.

[0096] Further, in some embodiments of the present disclosure, the column head node 240 specifically includes a column head end plate 2430 for providing a bearing plane, the column head end plate 2430 is arranged perpendicular to the connection plate 2410, and the column head end plate 2430 is embedded between the two connecting ear plates 2420, and is welded and fixed to the two connecting ear plates 2420 at the same time, so that the column head end plate 2430 and the two connecting ear plates 2420 form a stable I-shaped structure, thereby improving the structural stability of the column head node 240. At the same time, the column head end plate 2430 is also used to provide a stable installation platform for the reducer, and the reducer is arranged on the column head end plate 2430. Through the bearing plane of the column head end plate 2430, the reducer can work stably for a long time during the exhibition. The connecting ear plate 2420 is a bent plate of an integral structure to reduce the risk of stress concentration that may be generated by the splicing structure. The bending angle is designed to be 135°-170°, that is, the acute angle between the two areas on the connecting ear plate 2420 is maintained at 20°-90°, so as to maintain the stability of its bending structure and maintain the smooth transmission of the force from the bending area to the other side while achieving bending. In a specific embodiment of the present disclosure, the bending angle of the connecting ear plate 2420 is designed to be 165°. After the two connecting ear plates 2420 are fixed on the connecting plate 2410, they can form a 30° expansion angle, thereby allowing the two inclined cables 320 to form an angle of 30°, so as to provide sufficient support and connection strength, while avoiding affecting the tensioning performance of the inclined cables 320 due to excessively large or small bending angles.

[0097] At the same time, the setting of the column end plate 2430 can also realize the effective transmission of the force of the inclined cable 320, that is, the inclined cable 320 can realize the stable tightening of the reducer through the column end plate 2430, thereby improving the operating stability of the main cable 310 during the process of the reducer realizing the rotation adjustment of the main cable 310.

[0098] In addition, it should be noted that Fig.10 As shown, the column head node 240 provided in the embodiment of the present disclosure also includes a combined plate 2450, which is arranged parallel to the connecting disk 2410, and the connecting ear plate 2420 and the column head end plate 2430 are both fixed on the combined plate 2450. The number of combined plates 2450 can be increased according to the strength requirement of the column head node 240, and it should be noted that a combined plate 2450 is abutted on the side of the column head end plate 2430 facing the connecting disk 2410, and is welded and fixed to the combined plate 2450, so that the rotational force of the reducer borne by the column head end plate 2430 can be directly transmitted to the combined plate 2450 through the column head end plate 2430, and then directly transmitted to the connecting ear plates 2420 on both sides through the combined plate 2450, and carried by the inclined cable 320, so as to ensure the stability of the column head node 240 during rotation.

[0099] It should be noted that in some embodiments of the present disclosure, Fig.10 and Fig.18 As shown, in the connection structure of the column node 240, the bottom of the connecting ear plate 2420 is fixedly connected to the connecting disk 2410, and the area where the connecting disk 2410 extends out for the fixed connection of the inclined cable 320 is in an arc-shaped upturned structure. It not only provides sufficient extending space for the fixation of the inclined cable 320 to avoid interference between the inclined cable 320 and the connecting disk 2410 and other structures, thereby causing wear problems, but also the arc-shaped upturned structure can reduce the risk of stress concentration on the connecting ear plate 2420 when the inclined cable 320 generates an oblique tension force. At the same time, for the docking area between the connecting ear plate 2420 and the column head end plate 2430, the column head end plate 2430 is provided with an avoidance notch 2460, so that the connecting ear plate 2420 and the column head end plate 2430 have a certain gap in the docking area in the vertical direction, and provide a certain assembly error, so as to avoid the weld seam being difficult to connect and the risk of mutual extrusion force generated when the connecting ear plate 2420 and the column head end plate 2430 are in close contact. Furthermore, the two sharp corner areas where the column head end plate 2430 and the combined plate 2450 are connected are chamfered to form two connecting notches 2470. The position of the connecting notch 2470 can avoid the risk of stress concentration between the column head end plate 2430 and the combined plate 2450. At the same time, this is the intersection area of ​​three welds, and the notch setting can also provide sufficient setting space for the intersection area of ​​the welds, thereby avoiding the welding failure problem caused by abnormal stacking of welds.

[0100] Furthermore, in some embodiments of the present disclosure, a plurality of column base plates 2110 are evenly arranged along the circumferential direction at the bottom of the support column 210 to enhance the connection effect between the bottom of the support column 210 and the base 10 and reduce the risk of shaking of the support column 210; and the column head end plate 2430 and the column base plate 2110 are both arranged perpendicular to the base 10, so that the support column 210 plays a role of vertical support in the entire photovoltaic bracket, thereby ensuring the structural stability of the entire bracket.

[0101] In addition, it should be noted that Fig.15 As shown, the support column 210 provided in the embodiment of the present disclosure can also adopt a split structure, that is, the support column 210 is a multi-section support part 2120 that is split and assembled at the exhibition site to reduce the storage and transportation costs of the support column 210; and specifically, the docking area of ​​the adjacent support parts 2120 is provided with a support plate 2130, and the outer diameter of the support plate 2130 is larger than that of the support part 2120, so that the two support plates 2130 have a larger docking area, and the structural stability of the support column 210 after assembly is improved. At the same time, the two support plates 2130 are assembled and locked by a plurality of bolts uniformly arranged along the circumference, and a second reinforcing plate 2140 is arranged between each support part 2120 and the support plate 2130. The second reinforcing plate 2140 is similar to the structure of the column foot plate 2110, and both are triangular structures, so as to improve the connection effect between the support part 2120 and the support plate 2130, and ensure the structural stability of the assembled support column 210, so that the photovoltaic bracket shows the performance characteristics of high efficiency, flexibility and reliability in the exhibition scene. It should be noted that in some embodiments of the present disclosure, six bolts with a specification of not less than M10×45 are used to fix two adjacent support parts 2120; and the position where the support column 210 is connected to the base 10 is fixed with eight bolts with a specification of M16×60, and the outer periphery of the above-mentioned bolts is provided with two flat washers and one elastic washers when being fixed.

[0102] Furthermore, in order to enhance the stability of the structure of the base 10, in some embodiments of the present disclosure, considering that the force of the inclined cable 320 on the base 10 is an oblique force, a counterweight 130 is also provided in the area near the first end of the inclined cable 320 on the base 10. The counterweight 130 is formed by stacking a plurality of hot-dip galvanized steel plates to directly resist the overturning moment generated by the inclined cable 320 when it is subjected to force. The counterweight 130 is arranged in parallel with the connecting beam 120 and is clamped between two adjacent load-bearing beams 110. The clamping structure not only ensures the stable installation of the counterweight 130, but also enables the counterweight 130 to form an integral structure with the load-bearing beam 110 and the connecting beam 120 of the base 10, further enhancing the anti-overturning ability and stability of the base 10. At the exhibition site, this structural design of the counterweight 130 can significantly enhance the anti-overturning ability of the photovoltaic bracket, and it can be adaptively set according to the needs of the exhibition. It should be noted that in one embodiment of the present disclosure, a single counterweight block 130 is formed by stacking 8 hot-dip galvanized steel plates with a length of 700 mm, a width of 260 mm, and a thickness of 20 mm, and is arranged at both ends of the load-bearing beam 110 in the length direction, and four groups of counterweight blocks 130 are arranged at a single end of the load-bearing beam 110.
