However, in the prior art, if the wall thickness of the column is thin, the quality of welding is difficult to be guaranteed, and the load-bearing capacity of the diagonal brace is limited. If it is subjected to a large load, it is easy to open the weld at the weld, resulting in a break at the connection between the diagonal brace and the column, and the overall structure is not stable enough.

[0032] A diagonal brace assembly structure of a photovoltaic support, as Figures 1 to 6 shown, includes: a column 100, a diagonal brace 200, and a fixing assembly 300. The diagonal brace 200 is connected to the column 100 through the fixing assembly 300; the fixing assembly 300 includes an integrally formed fixing sleeve 320 and a fixing base plate 310. The fixing base plate 310 is fixedly connected to the column 100 through a first locking portion; a fixing sleeve 320 is provided on a side of the fixing base plate 310 facing away from the column 100. The fixing sleeve 320 is provided with a cavity with an open end. The diagonal brace 200 is inserted into the cavity of the fixing sleeve 320 through the opening and is connected to the fixing sleeve 320 through a second locking portion; the first locking portion includes: two or more first through bolts 411 and matching first nuts 412; the first through bolts 411 penetrate through the fixing base plate 310 and the column 100, and the first nuts 412 are sleeved on the first through bolts 411 and are closely attached to the outer side wall of the column 100, suitable for fixedly connecting the fixing base plate 310 and the column 100; the second locking portion includes: two or more second through bolts 421 and matching second nuts 422; the second through bolts 421 penetrate through the fixing sleeve 320 and the diagonal brace 200, and the second nuts 422 are sleeved on the second through bolts 421 and are closely attached to the outer side wall of the fixing sleeve 320, suitable for fixedly connecting the diagonal brace 200 and the fixing sleeve 320; a stiffening plate 330 is provided between the fixing sleeve 320 and the fixing base plate 310, and the stiffening plate 330 is suitable for providing support for the fixing sleeve 320.

[0033] It should be noted here that the upright column 100 provides stable support for the photovoltaic module, and the diagonal brace 200 can provide lateral support force for the photovoltaic module, effectively preventing the upright column 100 from tilting or twisting when subjected to external forces, improving the stability of the overall structure. The diagonal brace 200 and the upright column 100 are connected by a fixing component 300 to form a stable structure. The fixing component 300 ensures a firm and reliable connection between the diagonal brace 200 and the upright column 100, enabling the upright column 100 and the diagonal brace 200 to work together to jointly bear various loads, enhancing the stability of the overall structure of the photovoltaic support, and preventing the photovoltaic support from shaking or deforming due to loose connections. The fixing sleeve 320 and the fixing base plate 310 of the fixing component 300 are integrally formed, having good stability and reliability, being shock-proof and impact-resistant, and can ensure the connection strength.

[0034] The first locking part can tightly fix the fixing base plate 310 on the upright column 100, ensuring a firm and reliable connection between the fixing base plate 310 and the upright column 100. This connection method can withstand large tensile and shear forces, preventing the fixing base plate 310 from loosening or shifting during use. The fixing sleeve 320 is provided with a cavity with one end open, enabling the diagonal brace 200 to be conveniently inserted therein, simplifying the installation process of the diagonal brace 200. The open design facilitates adjusting the insertion depth and angle of the diagonal brace 200, ensuring the accurate connection position between the diagonal brace 200 and the upright column 100. After the diagonal brace 200 is inserted into the cavity of the fixing sleeve 320, it is connected to the fixing sleeve 320 through the second locking part, which can increase the contact area and friction of the connection. This connection method can effectively transmit the force between the diagonal brace 200 and the upright column 100, ensuring the stability of the structure. The design of the preset angle enables the fixing sleeve 320 to provide a support force in a specific direction for the diagonal brace 200. The preset angle matches the force direction of the diagonal brace 200, reducing local stress concentration and improving the support effect.

[0035] As Figure 2 shown, the stiffening plate 330 connects the fixing sleeve 320 and the fixing base plate 310, increasing the contact area and connection points between the two, further improving the connection strength and stability between the fixing sleeve 320 and the fixing base plate 310. When the diagonal brace 200 is subjected to external forces, the stiffening plate 330 can disperse the force borne by the fixing sleeve 320 and evenly transfer it to the fixing base plate 310, effectively preventing the fixing sleeve 320 from deforming, improving the load-bearing capacity of the fixing sleeve 320, and extending the service life of the fixing sleeve 320.

[0036] Compared with the welding method, in the connection method of the present application, after the column 100 and the diagonal brace 200 are connected through the fixed sleeve 320 and the fixed base plate 310 and locked by the first locking part and the second locking part, a fixed connection can be achieved without complex welding procedures, reducing the installation time. After welding connection, anti-corrosion treatment is required to extend the service life. However, by selecting the method of mutual cooperation of the fixed sleeve 320, the fixed base plate 310, the first locking part and the second locking part for fixation, no additional anti-corrosion measures are required, reducing the installation cost. Moreover, this connection method can better ensure the stability between the column 100 and the diagonal brace 200, avoiding the risk of open welding or breakage at the connection between the column 100 and the diagonal brace 200 due to poor welding quality, thus ensuring the stability of the overall structure of the photovoltaic bracket.

[0037] Further, as Figure 1 shown, two or more first through bolts 411 respectively penetrate through the fixed base plate 310 and the column 100 and are respectively connected to the corresponding first nuts 412. Two or more first nuts 412 are respectively closely attached to the outer side wall of the column 100. By tightening the first nuts 412, the first nuts 412 move along the axial direction of the corresponding first through bolts 411 to realize the clamping between the fixed base plate 310 and the column 100, avoiding the loosening of the column 100 and the fixed base plate 310 under the action of external forces, and ensuring the stability and reliability of the overall structure. The design of the first through bolts 411 and the first nuts 412 makes the installation and disassembly of the fixed base plate 310 and the column 100 more convenient and fast, which can improve the construction efficiency. When it is necessary to repair or replace the fixed component 300, the fixed base plate 310 can be easily disassembled from the column 100. Among them, it should be noted that the first through bolts 411 and the first nuts 412 adopt the through bolts and nuts with the model of M10 in the prior art.

[0038] Further, as Figure 1 shown, the second through bolts 421 penetrate through the fixed sleeve 320 and the diagonal brace 200 and are respectively connected to the corresponding second nuts 422. Two or more second nuts 422 are respectively closely attached to the outer side wall of the fixed sleeve 320. By tightening the second nuts 422, the second nuts 422 move along the axial direction of the corresponding second through bolts 421 to realize the clamping between the fixed sleeve 320 and the diagonal brace 200, ensuring the stability and reliability of the overall structure. The design of the second through bolts 421 and the second nuts 422 makes the installation and disassembly of the fixed sleeve 320 and the diagonal brace 200 more convenient and fast, which can improve the construction efficiency. When it is necessary to repair or replace the diagonal brace 200, the diagonal brace 200 can be easily disassembled from the fixed sleeve 320. Among them, it should be noted that the second through bolts 421 and the second nuts 422 adopt the through bolts and nuts with the model of M10 in the prior art.

[0039] In a possible implementation, a preset angle is provided between the longitudinal direction of the fixed sleeve 320 and the plane where the fixed base plate 310 is located, and the value range of the preset angle is: 30° to 60°.

[0040] In a possible implementation, as Figure 3 , Figure 4 shown, the main bodies of the upright column 100 and the diagonal brace 200 are both rectangular tubular structures. It should be noted here that the rectangular tubular structure reduces the self-weight of the upright column 100 and the diagonal brace 200, helps to reduce the burden on the foundation structure, reduces the installation cost, and at the same time, the rectangular structure is easy to achieve standardized manufacturing, making the installation and maintenance of the upright column 100, the diagonal brace 200 and the fixing component 300 more simple and fast, reducing the labor intensity and improving the installation efficiency.

[0041] In a possible implementation, as Figure 2 shown, the main body of the fixed sleeve 320 is in a tubular structure, and the size of the fixed sleeve 320 is larger than the size of the diagonal brace 200. It should be noted here that the size of the fixed sleeve 320 is larger than the size of the diagonal brace 200, and the diagonal brace 200 can be easily inserted into the cavity of the fixed sleeve 320, so as to realize the connection between the diagonal brace 200 and the fixed sleeve 320, making the installation and disassembly of the diagonal brace 200 and the fixed sleeve 320 more simple and improving the work efficiency.

[0042] Preferably, the gap between the fixed sleeve 320 and the diagonal brace 200 is 2 mm. The 2-mm gap allows the diagonal brace 200 to be easily inserted into the cavity of the fixed sleeve 320 without excessive force and precision requirements, simplifying the installation process. At the same time, the 2-mm gap can provide a certain tolerance space when installing the diagonal brace 200 to ensure that the diagonal brace 200 and the fixed sleeve 320 can still be assembled smoothly.

[0043] In a possible implementation, the main body of the fixed base plate 310 is in a rectangular plate-like structure. It should be noted here that the fixed base plate 310 with a rectangular plate-like structure has good stability, can evenly disperse the load from the fixed sleeve 320, and reduce the stress concentration phenomenon.

[0044] Preferably, the value range of the thickness of the fixed base plate 310 is: ≥3 mm, and the value range of the wall thickness of the fixed sleeve 320 is: ≥3 mm.

[0045] In a possible implementation, as Figure 1As shown in the figure, there are four first through bolts 411; the four first through bolts 411 are respectively located at the four corners of the fixed bottom plate 310. This layout enables the fixed bottom plate 310 to evenly disperse the stress to the upright columns 100 when stressed, avoiding deformation of the fixed bottom plate 310 when stressed, and improving the overall stability and load-bearing capacity.

[0046] Further, as Figures 1 to 3 shown, first mounting holes 311 are provided at the four corners of the fixed bottom plate 310, and four first through holes 110 are provided on each of the two opposite side walls of the upright column 100. The first through holes 110 are correspondingly arranged with the first mounting holes 311. The fixed bottom plate 310 is closely attached to the outer side wall of the upright column 100. The four first through bolts 411 respectively pass through the four first mounting holes 311 and the four first through holes 110 and are respectively connected to the corresponding four first nuts 412. By rotating the first nuts 412, the four first nuts 412 are all closely attached to the outer side wall of the side of the upright column 100 away from the fixed bottom plate 310 to provide sufficient clamping force, thereby fixedly installing the fixed bottom plate 310 on the outer side wall of the upright column 100.

[0047] In a possible implementation manner, as Figure 1 shown, there are two second through bolts 421. The two second through bolts 421 are respectively located on two adjacent side surfaces of the fixed sleeve 320, and the longitudinal directions of the two second through bolts 421 are perpendicular to each other. It should be noted here that the strut 200 inside the fixed sleeve 320 is tightened from different directions to prevent the fixation between the fixed sleeve 320 and the strut 200 from loosening or failing due to the force in a single direction, ensuring the stability and reliability of the connection between the fixed sleeve 320 and the strut 200. When the fixed sleeve 320 is subjected to external forces from different angles, the two perpendicular second through bolts 421 can jointly bear the stress and improve the anti-external force ability of the overall structure.

[0048] Further, as Figure 1 、 Figure 2 、 Figure 4 shown, two second mounting holes 321 are provided on two opposite side walls of the fixed sleeve 320. The two second mounting holes 321 are oppositely arranged. Correspondingly, two second through holes 210 are provided on each of the two opposite side walls of the strut 200. The two second through holes 210 are correspondingly arranged with the two second mounting holes 321. When the strut 200 is inserted into the fixed sleeve 320, one of the second through bolts 421 sequentially passes through the second mounting hole 321, the two second through holes 210 and the second mounting hole 321, and the second nut 422 locks the second through bolt 421, thereby realizing the first layer of locking of the second locking part on the fixed sleeve 320 and the strut 200.

[0049] Further, two third mounting holes 322 are formed on two opposite side walls of the fixed sleeve 320. The two third mounting holes 322 are oppositely arranged, and the third mounting holes 322 are located on one side adjacent to the side surface of the fixed sleeve 320 where the second mounting hole 321 is located. Third through holes are formed on two opposite side walls of the stay 200, and the third through holes are located on one side adjacent to the side surface of the stay 200 where the second through hole 210 is located. The two third through holes are correspondingly arranged with the two third mounting holes 322. When the stay 200 is inserted into the fixed sleeve 320, another second through-bolt 421 sequentially passes through the third mounting hole 322, the two third through holes and the third mounting hole 322, and the second nut 422 locks the second through-bolt 421 to achieve the second layer of locking between the fixed sleeve 320 and the stay 200 by the second locking portion.

[0050] In a possible implementation manner, as Figure 1 , Figure 2 shown, there are three stiffening plates 330; the three stiffening plates 330 are respectively located on three outer side walls of the fixed sleeve 320. It should be noted here that the stiffening plate 220 and the fixed sleeve 320 are integrally formed. The three stiffening plates 330 can share the external force borne by the fixed sleeve 320. When the external stress received by the stay 200 is transmitted to the fixed sleeve 320, the stiffening plates 330 can effectively disperse the stress, prevent the fixed sleeve 320 from deforming or being damaged due to excessive local stress, increase the load-bearing capacity of the fixed sleeve 320, and enable it to adapt to heavier load requirements.
