Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic brackets, and in particular to a column assembly structure of a photovoltaic bracket. Background Art

[0002] During the design and construction of photovoltaic brackets, since the length of the columns cannot be standardized, multiple columns need to be spliced ​​on site. The traditional column splicing method is usually to weld the connection between the two columns. However, when welding the two columns, the quality of welding is difficult to guarantee due to the thin wall thickness of the columns. In addition, the welding process is cumbersome and requires additional anti-corrosion measures. In harsh environments, the connection between the columns is prone to loosening or deformation. The load-bearing capacity of the welded columns is limited. If they are subjected to a large load, it is easy for the weld to open, resulting in a break between the two columns and an unstable overall structure.

[0003] Therefore, how to stably splice the columns of a photovoltaic support has become a technical problem that needs to be urgently solved by those skilled in the art. Summary of the invention

[0004] In view of this, the present application proposes a photovoltaic support column splicing structure, which is suitable for stably splicing the photovoltaic support columns.

[0005] According to one aspect of the application, a column assembly structure of a photovoltaic support is provided, comprising: a first column, a second column and a fixing assembly;

[0006] One end of the first column abuts against one end of the second column;

[0007] The fixing assembly includes a fixing sleeve and two locking parts, and the first column and the second column are respectively connected to the fixing sleeve through the two locking parts;

[0008] Each locking part includes: a first bolt assembly, a second bolt assembly and a third bolt assembly, wherein the first bolt assembly, the second bolt assembly and the third bolt assembly of one locking part all penetrate the fixed sleeve and the first column, and are suitable for fixedly connecting the fixed sleeve and the first column; the first bolt assembly, the second bolt assembly and the third bolt assembly of the other locking part all penetrate the fixed sleeve and the second column, and are suitable for fixedly connecting the fixed sleeve and the second column.

[0009] In a possible implementation, the first column, the second column and the main body of the fixed sleeve are all rectangular tubular structures.

[0010] In a possible implementation manner, the inner diameter of the fixing sleeve is larger than the outer diameter of the first column, and the outer diameter of the first column is the same as the outer diameter of the second column.

[0011] In a possible implementation, the first bolt assembly, the second bolt assembly, and the third bolt assembly all include bolts and nuts;

[0012] The bolt passes through the fixed sleeve and the first column; the nut is sleeved on the bolt and is closely attached to the outer side wall of the fixed sleeve.

[0013] In a possible implementation, the first bolt assembly and the second bolt assembly are located on the same side of the fixed sleeve and are arranged along the length direction of the fixed sleeve, and the third bolt assembly is located on a side of the fixed sleeve adjacent to the side of the first bolt assembly and the second bolt assembly.

[0014] In a possible implementation, the length direction of the bolt of the first bolt assembly and the length direction of the bolt of the second bolt assembly are parallel to each other;

[0015] The length direction of the bolts of the first bolt assembly and the length direction of the bolts of the third bolt assembly are perpendicular to each other.

[0016] In a possible implementation manner, the third bolt assembly is located between the first bolt assembly and the second bolt assembly.

[0017] Beneficial effects of this application

[0018] By setting a fixed sleeve and a locking part, it is only necessary to insert the first column and the second column into the cavity of the fixed sleeve and fix them using the locking part. No complicated welding process is required, which reduces the installation time. The fixed sleeve method does not require additional anti-corrosion measures, which reduces the installation cost. The connection method of the fixed sleeve can better ensure the stability between the first column and the second column, avoiding the risk of open welding or breakage at the connection between the first column and the second column due to poor welding quality, thereby ensuring the stability of the overall structure of the photovoltaic bracket.

[0019] The length direction of the bolts of the first bolt assembly and the length direction of the bolts of the third bolt assembly are perpendicular to each other. The bolts of the first bolt assembly and the bolts of the third bolt assembly form cross supports, thereby providing fixing effects in different directions, ensuring the overall strength of the overall photovoltaic support structure.

[0031] Figure 1 A schematic diagram showing the main structure of the column splicing structure of the photovoltaic support of the present application; Figure 2 A schematic diagram showing the main structure of the first column of the present application is shown; Figure 3 A schematic diagram showing the main structure of the second column of the present application is shown; Figure 4 A schematic diagram showing the main structure of the fixed sleeve of the present application is shown; Figure 5 The main structure schematic diagram of the bolts and nuts of the present application is shown. The present application proposes a column splicing structure of a photovoltaic support, including: a first column 200, a second column 300 and a fixing assembly; one end of the first column 200 is abutted against one end of the second column 300; the fixing assembly includes a fixing sleeve 100 and two locking parts, and the first column 200 and the second column 300 are respectively connected to the fixing sleeve 100 through the two locking parts; each locking part includes: a first bolt assembly, a second bolt assembly and a third bolt assembly, wherein the first bolt assembly, the second bolt assembly and the third bolt assembly of one locking part all penetrate the fixing sleeve 100 and the first column 200, and are suitable for fixing and connecting the fixing sleeve 100 and the first column 200; the first bolt assembly, the second bolt assembly and the third bolt assembly of another locking part all penetrate the sleeve and the second column 300, and are suitable for fixing and connecting the sleeve and the second column 300.

[0032] It should be noted here that the first column 200 and the second column 300 provide stable support for the photovoltaic bracket, one end of the first column 200 is abutted against one end of the second column 300; the first column 200 and the second column 300 are respectively connected to the sleeve through two locking parts; the fixed sleeve 100 is sleeved at the connection between the first column 200 and the second column 300, and the fixed sleeve 100 wraps the connection between the first column 200 and the second column 300 to form a stable connection point, thereby limiting the first column 200 and the second column 300 in the cavity of the fixed sleeve 100, effectively preventing the first column 200 and the second The column 300 is displaced under the action of external force, thereby ensuring a stable connection between the first column 200 and the second column 300. By providing the fixing sleeve 100, the structural strength of the connection between the first column 200 and the second column 300 is enhanced, and the phenomenon of breaking of the connection between the first column 200 and the second column 300 due to external force is avoided. The two locking parts respectively fix the first column 200, the second column 300 and the fixing sleeve 100. Through the combination of the fixing sleeve 100 and the locking part, a stable connection between the first column 200 and the second column 300 is achieved, ensuring the integrity and safety of the overall structure.

[0033] The first bolt assembly, the second bolt assembly and the third bolt assembly of one locking part penetrate the fixed sleeve 100 and the first column 200, and are suitable for fixing and connecting the fixed sleeve 100 and the first column 200. The first bolt assembly, the second bolt assembly and the third bolt assembly of the other locking part penetrate the sleeve and the second column 300, and are suitable for fixing and connecting the fixed sleeve 100 and the second column 300. Through the cooperation of the two first bolt assemblies, the two second bolt assemblies, the two third bolt assemblies and the fixed sleeve 100, the connection between the first column 200 and the second column 300 has good stability, and is also convenient for installation, maintenance and disassembly. The two first bolt assemblies, the two second bolt assemblies and the two third bolt assemblies make the first column 200, the second column 300 and the fixed The connection between the sleeves 100 is tighter. Compared with the welding method, by setting the fixed sleeve 100 and the locking part, it is only necessary to insert the first column 200 and the second column 300 into the cavity of the fixed sleeve 100 and fix them using the locking part. No complicated welding process is required, which reduces the installation time. After the welding connection, anti-corrosion treatment is required to extend the service life. The fixed sleeve 100 method is used for fixing without additional anti-corrosion measures, which reduces the installation cost. The connection method of the fixed sleeve 100 can better ensure the stability between the first column 200 and the second column 300, and avoids the risk of open welding or breakage at the connection between the first column 200 and the second column 300 due to poor welding quality, thereby ensuring the stability of the overall structure of the photovoltaic bracket.

[0034] In one possible implementation, the main bodies of the first column 200, the second column 300 and the fixed sleeve 100 are all rectangular tubular structures. It should be noted here that the rectangular tubular structure reduces the dead weight of the first column 200 and the second column 300, helps to reduce the burden of the basic structure, and reduces the installation cost. At the same time, the rectangular structure is easy to achieve standardized manufacturing, making the installation and maintenance of the first column 200, the second column 300 and the fixed sleeve 100 easier and faster, reducing labor intensity and improving installation efficiency.

[0035] In a possible implementation, the inner diameter of the fixing sleeve 100 is greater than the outer diameter of the first column 200 , and the outer diameter of the first column 200 is the same as the outer diameter of the second column 300 . It should be noted here that the inner diameter of the fixed sleeve 100 is larger than the outer diameter of the first column 200, and the first column 200 and the second column 300 can be easily inserted into the cavity of the fixed sleeve 100, so that the first column 200 and the second column 300 are connected to the fixed sleeve 100, making the installation and disassembly of the first column 200, the second column 300 and the fixed sleeve 100 easier, thereby improving work efficiency. The outer diameter of the first column 200 is the same as the outer diameter of the second column 300, so that the force applied to the connection between the first column 200 and the second column 300 can be more evenly distributed to each part, thereby avoiding damage to the connection between the first column 200 and the second column 300 caused by uneven force, thereby ensuring the stability of the overall structure. At the same time, the first column 200 and the second column 300 with the same outer diameter do not require complicated adjustment or alignment during assembly, thereby simplifying the installation process and improving work efficiency.

[0036] Furthermore, the difference between the inner diameter of the fixed sleeve 100 and the outer diameter of the first column 200 is 2 mm. The 2 mm gap allows the first column 200 and the second column 300 to be easily inserted into the cavity of the fixed sleeve 100 without requiring excessive force and precision, thereby simplifying the installation process. At the same time, the 2 mm gap can provide a certain tolerance space when installing the first column 200 and the second column 300, so that the first column 200 and the second column 300 can still be smoothly installed when the ground is uneven.

[0037] In one possible implementation, Figure 1As shown, the first bolt assembly, the second bolt assembly and the third bolt assembly all include bolts and nuts; the bolts penetrate the fixed sleeve 100 and the first column 200, and the nuts are sleeved on the bolts and tightly attached to the outer wall of the fixed sleeve 100. It should be noted here that the bolts are bolts with model XXX in the prior art, and the nuts are nuts with model XXX in the prior art. The bolts and nuts match each other. The first bolt assembly includes a first bolt 410 and a first nut 411, the second bolt assembly includes a second bolt 420 and a second nut 421, and the third bolt 430 assembly includes a third bolt 430 and a third nut 431. The first bolt 410, the second bolt 420 and the third bolt 430 penetrate the fixed sleeve 100 and the first column 200 respectively and are connected with the corresponding first nut 411, the second nut 421 and the third nut 431 respectively. The first bolt 410, the second bolt 420, the third bolt 430 and the corresponding first nut 411, the second nut 421 and the third nut 431 are connected to each other. The combination of the first nut 411, the second nut 421 and the third nut 431 provides a strong fastening force between the fixed sleeve 100 and the first column 200. The first nut 411, the second nut 421 and the third nut 431 are respectively close to the outer wall of the fixed sleeve 100. By tightening the first nut 411, the second nut 421 and the third nut 431, the first nut 411, the second nut 421 and the third nut 431 respectively move along the axial direction of the corresponding first bolt 410, the second bolt 420 and the third bolt 430 to achieve clamping between the fixed sleeve 100 and the first column 200, avoiding the first bolt 410, the second bolt 420 and the third bolt 430 from loosening under the action of vibration or external force, thereby ensuring the stability and reliability of the overall structure.

[0038] Further, such as Figure 1 As shown, the first bolt 410, the second bolt 420 and the third bolt 430 respectively penetrate the fixed sleeve 100 and the second column 300 and are connected with the corresponding first nut 411, the second nut 421 and the third nut 431 respectively. The first bolt 410, the second bolt 420, the third bolt 430 and the corresponding first nut 411, the second nut 421 and the third nut 431 provide a strong fastening force between the fixed sleeve 100 and the second column 300. The first nut 411, the second nut 421 and the third nut 431 are respectively The first nut 411, the second nut 421 and the third nut 431 are tightened so that the first nut 411, the second nut 421 and the third nut 431 respectively move along the axial direction of the corresponding first bolt 410, the second bolt 420 and the third bolt 430 to achieve clamping between the fixed sleeve 100 and the second column 300, thereby preventing the first bolt 410, the second bolt 420 and the third bolt 430 from loosening due to vibration or external force, thereby ensuring the stability and reliability of the overall structure.

[0039] In a possible implementation, the first bolt assembly and the second bolt assembly are located on the same side of the fixed sleeve 100 and are arranged and distributed along the body length direction of the fixed sleeve 100, and the third bolt assembly is located on the side adjacent to the side of the fixed sleeve 100 of the first bolt assembly and the second bolt assembly. It should be noted here that the first bolt assembly and the second bolt assembly are located on the same side of the fixed sleeve 100 and are arranged and distributed along the body length direction of the fixed sleeve 100, which facilitates the first bolt assembly and the second bolt assembly to fix the first column 200, the second column 300 and the fixed sleeve 100 sleeved at the connection between the first column 200 and the second column 300. The first bolt assembly and the second bolt assembly jointly bear the load from the first column 200, the second column 300 and the fixed sleeve 100, thereby improving the bearing capacity of the overall structure. The third bolt assembly is located on the side adjacent to the side of the fixed sleeve 100 of the first bolt assembly and the second bolt assembly, so that the force on the fixed sleeve 100 is more uniform, the stress concentration phenomenon is reduced, and the durability and safety of the overall structure are improved.

[0040] In one possible implementation, the body length direction of the first bolt 410 of the first bolt assembly and the body length direction of the second bolt 420 of the second bolt assembly are parallel to each other; the parallel arrangement enables the first bolt 410 of the first bolt assembly and the second bolt 420 of the second bolt assembly to evenly share the load and enhance the stability of the connection; at the same time, since the body length directions of the first bolt 410 and the second bolt 420 are the same, it is convenient for workers to install and disassemble, thereby improving operational efficiency; the body length direction of the first bolt 410 of the first bolt assembly and the body length direction of the third bolt 430 of the third bolt assembly are perpendicular to each other; the first bolt 410 of the first bolt assembly and the third bolt 430 of the third bolt assembly form a cross support, thereby providing fixing effects in different directions and ensuring the overall strength of the overall photovoltaic support structure.

[0041] In a possible implementation, the third bolt assembly is located between the first bolt assembly and the second bolt assembly. It should be noted that the third bolt assembly is arranged between the first bolt assembly and the second bolt assembly, so that the first bolt assembly, the second bolt assembly and the third bolt assembly form a more stable triangular connection relationship, thereby further improving the overall structural stability.

[0042] Further, such as Figure 1 , Figure 4As shown, two first mounting holes 110 are provided on two opposite side walls of the fixing sleeve 100, and the two first mounting holes 110 are arranged opposite to each other. The first bolt 410 of the first bolt assembly passes through the two first mounting holes 110 of the fixing sleeve 100 in sequence, so that the first bolt 410 of the first bolt assembly passes through the fixing sleeve 100; two second mounting holes 120 are provided on two opposite side walls of the fixing sleeve 100, and the two second mounting holes 120 are arranged opposite to each other. The second bolt 420 of the second bolt assembly passes through the two second mounting holes 120 of the fixing sleeve 100 in sequence, so that the second bolt 420 of the second bolt assembly passes through the fixing sleeve 100; the first mounting holes 110 and the second mounting holes 120 are arranged and distributed along the body length direction of the fixing sleeve 100.

[0043] Two third mounting holes 130 are provided on two opposite side walls of the fixing sleeve 100, and the two third mounting holes 130 are arranged opposite to each other. The third bolt 430 of the third bolt assembly passes through the two third mounting holes 130 of the fixing sleeve 100 in sequence, so that the third bolt 430 of the third bolt assembly passes through the fixing sleeve 100; the first mounting hole 110 and the third mounting hole 130 are respectively opened on opposite sides of the fixing sleeve 100, and the third mounting hole 130 is located between the first mounting hole 110 and the second mounting hole 120.

[0044] In one possible implementation, two first through holes 210 are respectively provided on two opposite side surfaces of the first column 200, and the two first through holes 210 are arranged opposite to the two first mounting holes 110. When the first column 200 passes into the interior of the fixed sleeve 100, the first bolt 410 of the first bolt assembly passes through the first mounting hole 110, the two first through holes 210 and the first mounting hole 110 in sequence, and the first nut 411 of the first bolt assembly is then tightened, thereby realizing the first layer of locking between the fixed sleeve 100 and the first column 200 by the first bolt assembly.

[0045] Two second through holes 220 are also respectively provided on opposite sides of the first column 200, and the two second through holes 220 are arranged opposite to the two second mounting holes 120. When the first column 200 passes into the interior of the fixed sleeve 100, the second bolt 420 of the second bolt assembly passes through the second mounting hole 120, the two second through holes 220 and the second mounting hole 120 in sequence, and the second nut 421 of the second bolt assembly locks it, thereby realizing the second layer of locking between the fixed sleeve 100 and the first column 200 by the second bolt assembly.

[0046] Two third through holes 230 are also respectively provided on opposite sides of the first column 200, and the two third through holes 230 are arranged opposite to the two third mounting holes 130. When the first column 200 passes into the interior of the fixed sleeve 100, the third bolt 430 of the third bolt assembly passes through the third mounting hole 130, the two third through holes 230 and the third mounting hole 130 in sequence, and the third nut 431 of the third bolt assembly locks it, thereby realizing the third layer of locking between the fixed sleeve 100 and the first column 200 by the third bolt assembly.

[0047] In one possible implementation, the specific structure and steps for locking the second column 300 with the fixed sleeve 100 through another locking portion are the same as the specific structure and steps for locking the first column 200 with the fixed sleeve 100 through one of the locking portions described above, which have been described in detail above and will not be repeated here.

[0048] It should be noted here that if Figure 1 As shown, the first bolt 410 of the first bolt assembly of one locking part and the second bolt 420 of the second bolt assembly and the first bolt 410 of the first bolt assembly of the other locking part and the second bolt 420 of the second bolt assembly are located on the same side of the fixed sleeve 100, and are equidistantly arranged along the body length direction of the fixed sleeve 100. The third bolt 430 of the third bolt assembly of one locking part and the third bolt 430 of the other locking part are located on the side adjacent to the side of the fixed sleeve 100 of the first bolt 410 of the first bolt assembly and the second bolt 420 of the second bolt assembly, and are equidistantly arranged along the body length direction of the fixed sleeve 100, so that the force on the fixed sleeve 100 is more uniform, the stress concentration phenomenon is reduced, and the durability and safety of the overall structure are improved.

Preferably, the reinforcement portion is elastic rubber.
