Description
Technical Field
[0001] The present application relates to the technical field of photovoltaic brackets, and in particular to a purlin assembly structure of a photovoltaic bracket. Background Art
[0002] Purlins are secondary beams in photovoltaic brackets and need to be assembled on site. The traditional way to install purlins is usually to weld the connection between the diagonal beams and purlins of the photovoltaic bracket. However, when welding the purlins and diagonal beams, due to the thin wall thickness of the diagonal beams, problems such as excessive heat-affected zones and poor weld formation are prone to occur during the welding process. The quality of welding is difficult to guarantee, and the welding process is cumbersome and requires additional anti-corrosion measures. In harsh environments, the connection between the diagonal beams and purlins is prone to loosening. The load-bearing capacity of the welded purlins is limited. If they are subjected to a large load, it is easy for the weld between the purlins and the diagonal beams to open, resulting in an unstable overall structure.
[0003] Therefore, how to stably assemble the purlins on the inclined beams of the photovoltaic support has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention
[0004] In view of this, the present application proposes a purlin assembly structure for a photovoltaic support, comprising: an inclined beam, a purlin and a fixing device;
[0005] The purlins and diagonal beams are placed crosswise, and the length direction of the purlins and the length direction of the diagonal beams are perpendicular to each other;
[0006] The fixing device comprises: an "X"-shaped clamp, a fastening assembly, a pad and two bolt assemblies; the open end of the "X"-shaped clamp is provided with a purlin, and two fixing ears of the "X"-shaped clamp are in contact with the inclined beam; the "X"-shaped clamp and the pad are respectively arranged on opposite sides of the inclined beam, and the pad is tightly fitted with the outer side wall of the inclined beam; the two fixing ears of the "X"-shaped clamp are respectively connected with the inclined beam and the pad through two bolt assemblies, and are suitable for connecting the inclined beam with the "X"-shaped clamp;
[0007] The "X"-shaped clamp is connected to the purlin through a fastening assembly.
[0008] In a possible implementation, the main bodies of the purlins and the diagonal beams are both rectangular tubular structures.
[0009] In one possible implementation, the fastening assembly includes a first bolt and a first nut; the first bolt passes through the I-shaped clamp and the purlin, and the first nut is sleeved on the first bolt and tightly attached to the outer side wall of the I-shaped clamp.
[0010] In one possible implementation, both bolt assemblies include a second bolt and a second nut; the two second bolts respectively penetrate the two fixing ears, the inclined beam and the pad of the I-shaped clamp in sequence, and the second nut is sleeved on the second bolt and tightly attached to the side of the pad away from the inclined beam.
[0011] In a possible implementation manner, the length direction of the first bolt is perpendicular to the length direction of the purlin.
[0012] In a possible implementation, the length directions of the two second bolts and the length direction of the inclined beam are perpendicular to each other.
[0013] In a possible implementation manner, the main body of the pad is a rectangular plate-shaped structure.
[0014] Beneficial effects of this application
[0015] The inclined beams and purlins can be connected by means of a "J"-shaped clamp and locked by a fixing device to achieve a fastened connection without the need for complicated welding procedures, thus reducing installation time.
[0016] The use of a combination of an I-shaped clamp and a fixing device for fixing does not require additional anti-corrosion measures, reducing installation costs. This connection method can better ensure the stability between the purlins and the diagonal beams, avoiding the risk of open welding or breakage at the connection between the diagonal beams and purlins due to poor welding quality, thereby ensuring the stability of the overall structure of the photovoltaic bracket.
[0017] By setting up fixing devices, the stability of the photovoltaic bracket is enhanced, ensuring that the connection between the purlins and the diagonal beams is firm and reliable, and preventing the bracket from shaking or deforming due to loose connections.
[0018] By providing two fixing ears and a pad of the I-shaped clamp, the direct pressure of the bolt assembly on the inclined beam is reduced, thereby protecting the inclined beam from damage and improving the connection quality of the entire photovoltaic bracket. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Figure 1 The main structure diagram of the purlin assembly structure of the photovoltaic support of the present application is shown; Figure 2 An exploded view of the main structure of the purlin assembly structure of the photovoltaic support of the present application is shown; Figure 3 A schematic diagram of the main structure of the X-shaped clamp of the present application is shown; Figure 4 A schematic diagram showing the main structure of the purlin of this application is shown; Figure 5 A schematic diagram showing the main structure of the inclined beam of the present application is shown; Figure 6 A schematic diagram showing the main structure of the pad of the present application is shown; Figure 7 A schematic diagram showing the main structure of the fastening assembly of the present application is shown; Figure 8 The main structure diagram of the bolt assembly of the present application is shown. The present application proposes a purlin assembly structure of a photovoltaic bracket, comprising: an inclined beam 200, a purlin 100, and a fixing device; the purlin 100 and the inclined beam 200 are placed crosswise, and the length direction of the purlin 100 is perpendicular to the length direction of the inclined beam 200; the fixing device comprises: an "X"-shaped clamp 300, a fastening assembly 110, a pad 400 and two bolt assemblies 210, the open end of the "X"-shaped clamp 300 is provided with a purlin 100, and the two ends of the "X"-shaped clamp 300 are provided with a The fixing ears are in contact with the inclined beam 200; the I-shaped clamp 300 and the pad 400 are respectively arranged on the opposite sides of the inclined beam 200, and the pad 400 is tightly fitted with the outer wall of the inclined beam 200; the two fixing ears of the I-shaped clamp 300 are respectively connected to the inclined beam 200 and the pad 400 through two bolt assemblies 210, which is suitable for connecting the inclined beam 200 with the I-shaped clamp 300; the I-shaped clamp 300 is connected to the purlin 100 through the fastening assembly 110.
[0034] It should be noted here that the purlin 100 and the diagonal beam 200 provide stable support for the photovoltaic bracket. The cross-placing of the purlin 100 and the diagonal beam 200 can evenly disperse the external load on the photovoltaic bracket, avoiding damage caused by single-point force. The purlin 100 and the diagonal beam 200 are connected by a fixing device to form a stable structure. By setting the fixing device, the stability of the photovoltaic bracket is enhanced, ensuring that the connection between the purlin 100 and the diagonal beam 200 is firm and reliable, and preventing the bracket from shaking or deforming due to loose connection.
[0035] The purlin 100 is located in the opening of the "J"-shaped clamp 300 and is fixed by the fastening assembly 110. This connection method forms a stable structure between the purlin 100 and the "J"-shaped clamp 300, which helps to resist external pressure and maintain the stability of the photovoltaic module. The "J"-shaped clamp 300 and the pad 400 are relatively arranged on both sides of the inclined beam 200. The two fixing ears of the "J"-shaped clamp 300 are in contact with the inclined beam 200, and the pad 400 is tightly fitted with the outer wall of the inclined beam 200. By setting the two fixing ears of the "J"-shaped clamp 300 and the pad 400, the direct pressure of the bolt assembly 210 on the inclined beam 200 is reduced, thereby protecting the inclined beam 200 from damage and improving the connection quality of the entire photovoltaic bracket.
[0036] Compared with the connection method of the present application and the welding method, the inclined beam 200 and the purlin 100 can be connected by the "J"-shaped clamp 300 and locked by the fixing device to achieve a fastened connection. There is no need for complicated welding procedures, which reduces the installation time. After the welding connection, anti-corrosion treatment is required to extend the service life. The "J"-shaped clamp 300 and the fixing device are used to cooperate with each other for fixing. There is no need for additional anti-corrosion measures, which reduces the installation cost. This connection method can better ensure the stability between the purlin 100 and the inclined beam 200, and avoid the risk of open welding or breakage at the connection between the inclined beam 200 and the purlin 100 due to poor welding quality, thereby ensuring the stability of the overall structure of the photovoltaic bracket.
[0037] In one possible implementation, Figure 4 , Figure 5 As shown, the main bodies of the purlin 100 and the inclined beam 200 are both rectangular parallelepiped tubular structures. It should be noted here that the rectangular parallelepiped tubular structure reduces the weight of the purlin 100 and the inclined beam 200, helps to reduce the burden of the basic structure, and at the same time, the rectangular parallelepiped structure is easy to realize standardized manufacturing, reducing the installation cost.
[0038] In one possible implementation, Figure 6 As shown, the main body of the pad 400 is a rectangular plate structure. It should be noted here that the rectangular plate structure of the pad 400 increases the contact area between the bolt assembly 210 and the inclined beam 200, effectively disperses the pressure generated by the bolt assembly 210, and avoids deformation or damage of the inclined beam 200 due to excessive local force.
[0039] In a possible implementation, the width of the "X"-shaped hoop 300 is greater than the width of the purlin 100, and the height of the "X"-shaped hoop 300 is greater than the height of the purlin 100. It should be noted here that the width of the "X"-shaped hoop 300 is greater than the width of the purlin 100, so that the purlin 100 can be completely embedded in the "X"-shaped hoop 300, thereby forming a stable connection structure. This design reduces the risk of slippage or falling off of the purlin 100 when subjected to force. The height of the "X"-shaped hoop 300 is designed to be higher than the purlin 100, which can more effectively restrain the deformation of the purlin 100, especially when subjected to loads in the vertical direction, the "X"-shaped hoop 300 can provide additional support to prevent the purlin 100 from bending or twisting. When the purlin 100 is subjected to external force, the design of the height and width of the "X"-shaped clamp 300 allows the stress to be more evenly distributed in the overall structure, avoiding the concentration of stress on the purlin 100, thereby ensuring that the purlin 100 is not damaged.
[0040] Furthermore, the difference between the opening width of the I-shaped clamp 300 and the width of the purlin 100 is 2 mm. The difference of 2 mm makes it easier for construction workers to put the purlin 100 into the I-shaped clamp 300 and fix it, ensuring the precise fit between the I-shaped clamp 300 and the purlin 100, while avoiding the loose or unstable connection between the I-shaped clamp 300 and the purlin 100 due to excessive gap, and also preventing the installation from being difficult due to excessive gap, thereby ensuring the stability of the overall structure.
[0041] In one possible implementation, the fastening assembly 110 includes a first bolt 111 and a first nut 112 . The first bolt 111 passes through the I-shaped clamp 3000 and the purlin 100 . The first nut 112 is sleeved on the first bolt 111 and is tightly attached to the outer wall of the I-shaped clamp 300 .
[0042] It should be noted here that if Figures 1 to 4As shown, first through holes 310 are symmetrically provided on opposite side walls of the "X"-shaped clamp 300, and correspondingly, a first mounting hole 120 is provided on the purlin 100. The two first through holes 310 are arranged opposite to the first mounting hole 120. The first bolt 111 passes through one of the first through holes 310 of the "X"-shaped clamp 300, the second through hole 320 of the purlin 100, and the other first through hole 310 of the "X"-shaped clamp 300, and then is connected with the first nut 112. The first bolt 111 is connected to the first nut 112 after passing through the first through hole 310 of the "X"-shaped clamp 300, the second through hole 320 of the purlin 100, and the other first through hole 310 of the "X"-shaped clamp 300. The combination of the first nut 111 and the first nut 112 provides a strong fastening force between the "X"-shaped clamp 300 and the purlin 100. The first nut 112 is tightly attached to the outer wall of the "X"-shaped clamp 300. By tightening the first nut 112, the first nut 112 moves along the axial direction of the first bolt 111 to achieve the clamping between the "X"-shaped clamp 300 and the purlin 100, thereby preventing the first bolt 111 from loosening under the action of vibration or external force, and ensuring the stability and reliability of the overall structure.
[0043] In one possible implementation, the two bolt assemblies 210 each include a second bolt 211 and a second nut 212; the two second bolts 211 respectively penetrate the two fixing ears of the I-shaped clamp 300, the inclined beam 200 and the pad 400 in sequence, and the second nut 212 is sleeved on the second bolt 211 and tightly attached to the side of the pad 400 away from the inclined beam 200.
[0044] like Figure 1 , Figure 3 , Figure 5 , Figure 6 As shown, the two fixing ears of the "X"-shaped clamp 300 are each provided with a second through hole 320, and the purlin 100 is located between the two second through holes 320. Correspondingly, the second mounting holes 220 are symmetrically provided on the inclined beam 200, and the fixing holes 410 are symmetrically provided on the pad 400. The second through holes 320 of the "X"-shaped clamp 300, the corresponding second mounting holes 220 of the inclined beam 200, and the corresponding fixing holes 410 of the pad 400 are arranged relatively, and the second bolts 211 penetrate the "X"-shaped clamp 300 in sequence. The second through hole 320 of the "X"-shaped clamp 300, the second mounting hole 220 of the inclined beam 200 and the fixing hole 410 of the pad 400 are connected with the second nut 212. By tightening the second nut 212, the second nut 212 moves along the axial direction of the second bolt 211 to achieve clamping between the "X"-shaped clamp 300, the inclined beam 200 and the pad 400, avoiding the loosening of the second bolt 211 under the action of vibration or external force, thereby ensuring the stability and reliability of the overall structure.
[0045] Preferably, the bolts 111 and nuts 112 of the fastening assembly 110 are bolts and nuts with a model of M10x75 in the prior art, and the bolts 111 and nuts 112 of the fastening assembly 110 match each other. The bolts 211 and nuts 212 of the bolt assembly 210 are bolts and nuts with a model of M10x120 in the prior art, and the bolts 211 and nuts 212 of the bolt assembly 210 match each other.
[0046] In one possible implementation, Figure 1 As shown, the length direction of the bolt 111 of the fastening assembly 110 is perpendicular to the length direction of the purlin 100. It should be noted here that the bolt 111 of the fastening assembly 110 can more effectively prevent the torsional deformation of the purlin 100 when subjected to lateral force, thereby ensuring the stability of the overall structure.
[0047] In a possible implementation, the length direction of the two second bolts 211 is perpendicular to the length direction of the inclined beam 200. Figure 1 As shown, the second bolt 211 and the inclined beam 200 form a cross support so as to provide a fixing effect in different directions, thereby ensuring the overall strength of the photovoltaic support structure. Furthermore, the length directions of the two second bolts 211 are arranged parallel to each other, and the parallel arrangement enables the two second bolts 211 to evenly share the load, thereby enhancing the stability of the connection between the "J"-shaped clamp 300, the inclined beam 200 and the pad 400. At the same time, since the length directions of the two second bolts 211 are the same, it is convenient for the staff to install and disassemble, thereby improving the operating efficiency.
