Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic brackets, and in particular to a photovoltaic bracket system for a concrete roof. Background Art

[0002] With the development of the photovoltaic industry, photovoltaic brackets are being used more and more widely. When traditional photovoltaic brackets are fixed on the top of the roof, in order to maintain their stability, the columns of the photovoltaic brackets usually need to be fixed on a concrete foundation with hinged column feet. Although the hinged column feet are simple in structure, they will cause one end of the column to swing with the hinged column feet as the rotation axis. Therefore, additional inter-column supports are required to make the force and deformation of the bracket meet the requirements of the specifications. However, the installation process of the inter-column supports is relatively complicated and requires precise measurement, positioning and installation operations, which leads to low overall installation efficiency and affects the beauty and simplicity of the overall structure. Summary of the invention

[0003] In view of this, the present application proposes a photovoltaic support system for a concrete roof, comprising: two mounting bases, two cantilever columns, an inclined beam, a photovoltaic module and a horizontal beam;

[0004] The length directions of the two cantilever columns are parallel to each other, and the bottom ends of the two cantilever columns are connected to the two mounting bases through two first fixing components respectively; the top ends of the two cantilever columns are connected to the bottom surface of the inclined beam through two second fixing components respectively, and the top surface of the inclined beam is placed with a photovoltaic component;

[0005] The first fixing assembly includes: a limiting sleeve and a placement base plate; the placement base plate is arranged on the top surface of the mounting base, the limiting sleeve is arranged on the side of the placement base plate away from the mounting base, and the length direction of the limiting sleeve is perpendicular to the plane where the placement base plate is located;

[0006] The main body of the limiting sleeve is a hollow columnar structure with an opening on the top surface, and the cantilever column is inserted into the cavity of the limiting sleeve through the top surface opening of the limiting sleeve;

[0007] The horizontal beam is arranged between the two mounting bases, and both ends of the horizontal beam are also connected to the two mounting bases through two first fixing components respectively.

[0008] In one possible implementation, the first fixing assembly further includes a first locking portion and a second locking portion; the placement base plate is fixedly connected to the mounting base via the first locking portion, and the limiting sleeve is fixedly connected to the cantilever column via the second locking portion.

[0009] In one possible implementation, the first fixing assembly further includes two or more reinforcing ribs; the two or more reinforcing ribs are disposed between the outer side wall of the limiting sleeve and the top surface on which the base plate is placed, and are suitable for providing stable support for the limiting sleeve.

[0010] In a possible implementation manner, first adjustment holes are provided at the four corners of the placement base plate. The first adjustment holes are in the shape of oblong holes, and the first locking portion is disposed through the first adjustment holes, which is suitable for mounting the placement base plate to the mounting base.

[0011] In a possible implementation manner, the second fixing component includes: a clamping member and a third locking portion; the top end of the cantilever column is inserted into the inner side of the clamping member and hinged to the clamping member, and the clamping member is fixedly connected to the inclined beam through the third locking portion.

At the same time, the first fixing component of the present application can meet the specification requirements of force and deformation without additional installation of column bracing, reducing the dependence on column bracing and installation cost, and improving the installation efficiency of the cantilever column.

[0017] By providing the horizontal beam, not only the stability of the two mounting bases is greatly improved, but also through the stiffness of the horizontal beam itself, the internal force and displacement between the two mounting bases are effectively coordinated and balanced. The overall structure of the photovoltaic support has been significantly improved in terms of anti-slip, anti-pull and anti-overturning capabilities, ensuring the stability of the overall structure.

It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0032] This application proposes a photovoltaic support system for a concrete roof, such as Figures 1 to 6 As shown, it includes: two mounting bases 100, two cantilever columns 110, an inclined beam 120, a photovoltaic module 140 and a horizontal beam 150; the length directions of the two cantilever columns 110 are parallel to each other, and the bottom ends of the two cantilever columns 110 are respectively connected to the two mounting bases 100 through two first fixing components 200; the top ends of the two cantilever columns 110 are respectively connected to the bottom surface of the inclined beam 120 through two second fixing components 300, and the top surface of the inclined beam 120 is placed with a photovoltaic module 140; the first fixing component 200 includes: a limiting sleeve 210 and a placement bottom plate 220; the placement bottom plate 220 is provided On the top surface of the mounting base 100, the limiting sleeve 210 is arranged on the side of the placement base 220 away from the mounting base 100, and the body length direction of the limiting sleeve 210 is perpendicular to the plane where the placement base 220 is located; the main body of the limiting sleeve 210 is a hollow columnar structure and an opening is provided on the top surface, and the cantilever column 110 is suitable for being inserted into the cavity of the limiting sleeve 210 through the top surface opening of the limiting sleeve 210; the horizontal beam 150 is arranged between the two mounting bases 100, and the two ends of the horizontal beam 150 are also connected to the two mounting bases 100 through two first fixing components 200 respectively.

[0033] It should be noted here that the installation base 100 is a concrete pier formed by pouring concrete. The two installation bases 100 are fixedly installed on the concrete roof, avoiding perforation damage to the concrete roof. At the same time, the two installation bases 100 provide stable support for the cantilever column 110, preventing the cantilever column 110 from tipping or shaking due to external forces and ensuring the stability of the overall structure. The two parallel cantilever columns 110 can evenly share the load in the vertical direction, improving the load-bearing capacity of the cantilever column 110. The first fixing component 200 firmly fixes the cantilever column 110 on the installation base 100, avoiding the shaking or displacement of the cantilever column 110. At the same time, the first fixing component 200 also plays a role in transmitting and dispersing the load to a certain extent, enabling the force borne by the cantilever column 110 to be evenly transmitted to the installation base 100. The cantilever column 110 provides effective support for the inclined beam 120 through the second fixing component 300. The inclined beam 120 is suitable for providing a support platform for the photovoltaic module 140. The load of the photovoltaic module 140 is transmitted to the cantilever column 110 through the second fixing component 300. The cantilever column 110, the second fixing component 300, the inclined beam 120 and the photovoltaic module 140 cooperate with each other, thus ensuring the stability of the overall structure.

[0034] The placement base plate 220 is installed on the top surface of the installation base 100. The placement base plate 220 provides a stable support plane for the installation of the cantilever column 110. The design that the limiting sleeve 210 is perpendicular to the placement base plate 220 can make the gravity and external forces on the cantilever column 110 be transmitted more directly to the placement base plate 220, reducing the shaking and displacement of the cantilever column 110 in the horizontal direction, ensuring that the connection between the cantilever column 110 and the first fixing component 200 is more stable, and improving the stability of the overall structure. The hollow columnar structure of the limiting sleeve 210 and its top opening design provide stable support for the cantilever column 110, enabling the cantilever column 110 to be conveniently inserted into the inside of the limiting sleeve 210, making the installation process of the cantilever column 110 simpler and more convenient.

[0035] Compared with the existing hinged column base method, the first fixing component 200 in this application significantly improves the overall stability and stiffness of the photovoltaic support, effectively avoiding the swing of the cantilever column 110 due to force. At the same time, the first fixing component 200 in this application can meet the specification requirements of force and deformation without additional installation of column bracing for fixation, reducing the dependence on column bracing and installation costs, and improving the installation efficiency of the cantilever column 110.

[0036] Both ends of the horizontal beam 150 are installed on opposite sides of the two mounting bases 100 through the first fixing component 200. The horizontal beam 150 is suitable for adjusting the internal force between the two mounting bases 100 to avoid displacement of the two mounting bases 100 due to uneven internal force distribution. By setting the horizontal beam 150, not only the stability of the two mounting bases 100 is greatly improved, but also the internal force and displacement between the two mounting bases 100 are effectively coordinated and balanced through the rigidity of the horizontal beam 150 itself. The overall structure of the photovoltaic bracket has been significantly improved in terms of anti-slip, anti-pulling and anti-overturning capabilities, ensuring the stability of the overall structure.

[0037] In one possible implementation, Figures 2 to 4 As shown, the main body of the limiting sleeve 210 is a rectangular parallelepiped structure, and one side of the limiting sleeve 210 adjacent to the placement base plate 220 is an open structure. It should be noted here that the limiting sleeve 210 with a rectangular structure has good stability and is suitable for providing a stable support for the cantilever column 110, so that the limiting sleeve 210 can withstand and transmit forces from all directions. One side of the limiting sleeve 210 is an open structure, so that when the limiting sleeve 210 is connected to the cantilever column 110, the cantilever column 110 can be more easily inserted into the cavity of the limiting sleeve 210. At the same time, the limiting sleeve 210 provides a limiting space for the cantilever column 110, thereby preventing the cantilever column 110 from shaking significantly when subjected to external forces. Since the cantilever column 110 is inserted into the cavity of the limiting sleeve 210, there is no direct connection between the cantilever column 110 and the placement base plate 220. When the cantilever column 110 is subjected to external forces, the stress generated will first be absorbed and dispersed by the limiting sleeve 210. The placement base plate 220 and the limiting sleeve 210 cooperate with each other to provide a guarantee for the stability and durability of the cantilever column 110.

[0038] In one possible implementation, Figure 1 As shown, the first fixing assembly 200 further includes a first locking portion 230 and a second locking portion 240; the placement base plate 220 is fixedly connected to the mounting base 100 through the first locking portion 230, and the limiting sleeve 210 is fixedly connected to the cantilever column 110 through the second locking portion 240. The tight connection between the placement base plate 220 and the mounting base 100 is ensured to prevent the cantilever column 110 from loosening. The second locking portion 240 fixes the cantilever column 110 in the cavity of the limiting sleeve 210. The cavity structure of the limiting sleeve 210 and the second locking portion 240 together provide the necessary supporting force for the cantilever column 110, preventing the cantilever column 110 from loosening or falling out of the cavity of the limiting sleeve 210 during use, and ensuring that the connection between the cantilever column 110 and the limiting sleeve 210 is firm and reliable.

[0039] Further, such as Figure 1As shown, the first locking portion 230 includes a first bolt and a first nut. The first bolt is pre-buried in the mounting base 100 and one end of the first bolt protrudes from the mounting base 100. The pre-buried method enables the cantilever column 110 to withstand greater tension and stress, effectively ensuring the stability of the overall structure. One end of the first bolt protrudes from the mounting base 100 to facilitate the subsequent installation of the placement base plate 220 and the first nut. The bottom surface of the placement base plate 220 is placed on the top surface of the mounting base 100. The placement base plate 220 is suitable for expanding the cantilever column 110 and the mounting base 100. The contact area of the mounting base 100 makes the cantilever column 110 more stable on the mounting base 100 and reduces shaking or displacement caused by external force. The first bolt passes through the placement base plate 220, and the first nut is sleeved on the first bolt and is located on the side of the placement base plate 220 away from the mounting base 100. The first nut and the first bolt cooperate with each other to lock the placement base plate 220 on the mounting base 100, ensuring a tight connection between the placement base plate 220 and the mounting base 100 and preventing the cantilever column 110 from loosening.

[0040] Furthermore, four first locking portions 230 are provided, and the four first locking portions 230 are centrally symmetrically arranged with the placement base plate 220 as the center.

[0041] In one possible implementation, Figure 2 As shown, the four corners of the placement base plate 220 are provided with first adjustment holes 221, which are in the shape of an oblong hole. The first bolt penetrates through the first adjustment holes 221 of the placement base plate 220 and is connected with the first nut, which is suitable for installing the placement base plate 220 on the mounting base 100. It should be noted here that the main body of the placement base plate 220 is in the shape of a rectangular plate. The placement base plate 220 of the rectangular plate structure has good stability, can evenly disperse the load from the first fixing assembly 200 and the cantilever column 110, and reduce stress concentration. The four first adjustment holes 221 are centrally symmetrically arranged on the placement base plate 220, and the length directions of each two adjacent first adjustment holes 221 are perpendicular to each other. The mutually perpendicular first adjustment holes 221 can make the first fixing assembly 200 be adjusted in two vertical directions respectively, ensuring that the placement base plate 220 can be accurately and firmly connected to the four first locking parts 230 on the mounting base 100.

[0042] In one possible implementation, Figure 2As shown, the second locking portion 240 includes a matching second bolt 241, a second nut 242 and a gasket 243; the gasket 243 and the limiting sleeve 210 are respectively located on the inner and outer sides of the cantilever column 110, and the limiting sleeve 210 is provided with a second adjustment hole 211. The second bolt 241 passes through the second adjustment hole 211 of the limiting sleeve 210, the cantilever column 110 and the gasket 243 in sequence. The second nut 242 is sleeved on the second bolt 241 and tightly attached to the side of the gasket 243 away from the cantilever column 110, which is suitable for locking the cantilever column 110 in the limiting sleeve 210.

[0043] Further, such as Figure 3 , Figure 4 As shown, the second adjustment hole 211 is an oblong hole structure and extends along the length direction of the limiting sleeve 210. Figure 2 As shown, the pad 243 is tightly fitted with the side wall of the cantilever column 110 and is located on the side away from the limiting sleeve 210. The pad 243 is suitable for increasing the contact area between the second bolt 241 and the cantilever column 110, effectively dispersing the pressure generated between the second bolt 241 and the second nut 242. The second bolt 241 passes through the second adjustment hole 211, the cantilever column 110 and the pad 243 in sequence and is connected with the second nut 242. The second nut 242 is sleeved on the second bolt 241 and tightly fitted. On the side of the pad 243 facing away from the cantilever column 110, the combination of the second bolt 241 and the second nut 242 provides a strong fastening force for the cantilever column 110 and the limiting sleeve 210. By screwing the second nut 242, the second nut 242 moves along the axial direction of the second bolt 241 to achieve clamping between the cantilever column 110, the limiting sleeve 210 and the pad 243, thereby avoiding the second bolt 241 from loosening due to vibration or external force, thereby ensuring the stability and reliability of the overall structure.

[0044] Further, such as Figure 1 , Figure 2 As shown, there are more than two second locking parts 240; the more than two second locking parts 240 are respectively located on each side of the limiting sleeve 210. By arranging more than two second locking parts 240 on each side of the limiting sleeve 210, multi-point locking can be achieved, thereby ensuring the stability of the connection between the cantilever column 110 and the limiting sleeve 210. When the limiting sleeve 210 is subjected to external force, the multi-point distribution design can more effectively resist deformation and loosening.

[0045] In one possible implementation, Figure 3 , Figure 4As shown, each side of the limiting sleeve 210 is provided with more than two second adjustment holes 211; and the more than two second adjustment holes 211 are arranged equidistantly along the length direction of the limiting sleeve 210. It should be noted here that the multiple second adjustment holes 211 provide more connection options, and suitable adjustment holes can be selected for connection according to actual needs, thereby improving the connection precision and accuracy between the cantilever column 110 and the limiting sleeve 210. Through the multiple equidistantly arranged second adjustment holes 211, the force on the limiting sleeve 210 can be dispersed to more points, avoiding damage or deformation caused by excessive force on a single point.

[0046] In one possible implementation, Figures 2 to 4 As shown, the first fixing assembly 200 further includes more than two reinforcing ribs 260 ; the more than two reinforcing ribs 260 are arranged between the outer side wall of the limiting sleeve 210 and the top surface of the bottom plate 220 , and are suitable for providing stable support for the limiting sleeve 210 .

[0047] It should be noted here that the reinforcing rib 260 connects the limiting sleeve 210 and the placement base plate 220, increases the contact area and connection points between the two, and improves the connection strength and stability between the limiting sleeve 210 and the placement base plate 220. When the cantilever column 110 is subjected to external force, the reinforcing rib 260 can disperse the force borne by the limiting sleeve 210 and transfer it evenly to the placement base plate 220, effectively avoiding deformation of the limiting sleeve 210, improving the bearing capacity of the limiting sleeve 210, and extending the service life of the limiting sleeve 210.

[0048] Furthermore, six reinforcing ribs 260 are provided; the plurality of reinforcing ribs 260 can effectively disperse and transfer stress, thereby reducing stress concentration, avoiding deformation of the limiting sleeve 210, and ensuring the stability of the limiting sleeve. Two reinforcing ribs 260 are provided on each outer side wall of the limiting sleeve, so that the limiting sleeve can evenly distribute stress when subjected to force, thereby avoiding damage caused by excessive local stress.

[0049] In one possible implementation, the base plate 220, the limiting sleeve 210 and the reinforcing rib 260 are connected by welding or integrally formed. The welding or integrally formed method can ensure a tight connection between the base plate 220, the limiting sleeve 210 and the reinforcing rib 260, thereby enhancing the strength and rigidity of the overall structure and ensuring the stability of the overall structure.

[0050] In one possible implementation, Figure 1As shown, the longitudinal direction of the horizontal beam 150 is perpendicular to the longitudinal direction of the cantilever column 110. In the same way, both ends of the horizontal beam 150 are respectively arranged on the opposite sides of two installation bases 100 through two first fixing components 200. The installation method of the horizontal beam 150 and the cantilever column 110 installed on the top of the installation base 100 through the first fixing component 200 is the same, which has been described in detail above and will not be elaborated here.

[0051] In a possible implementation manner, as Figure 1 、 Figure 5 shown, the second fixing component 300 includes: a clamping member and a third locking portion 330. The top end of the cantilever column 110 is inserted into the inner side of the clamping member and hinged to the clamping member. The clamping member is fixedly connected to the inclined beam 120 through the third locking portion 330. It should be noted here that the clamping member includes: two clamping plates 320 and a support plate 310; the main bodies of the two clamping plates 320 are in a triangular plate-like structure, and the two clamping plates 320 are arranged oppositely. The two clamping plates 320 are connected by the support plate 310. One end of the cantilever column 110 is located between the two clamping plates 320. The hinge bolt 340 passes through the two clamping plates 320 and the cantilever column 110. The hinge nut is sleeved on the hinge bolt 340 and is located on the side of the clamping plate 320 away from the cantilever column 110. The two clamping plates 320 rotate around the hinge bolt 340 to drive the inclined beam 120 to displace, so that the angle and orientation of the photovoltaic module 140 on the inclined beam 120 can be conveniently adjusted to make the most of solar energy resources. When the rotation is in place, it is locked by the hinge nut to avoid rotational displacement.

[0052] The third locking portion 330 includes a third bolt and a third nut; the two adjacent side edges of the two clamping plates 320 away from the cantilever column 110 are respectively fixedly connected to the support plate 310. The inclined beam 120 is located on the upper surface of the support plate 310. The third nut is fixedly arranged on the inclined beam 120. The third bolt passes through the support plate 310 and is fixedly connected to the third nut on the inclined beam 120. And the lower surface of the inclined beam 120 is in close contact with the support plate 310, so as to ensure the reliability of the connection between the inclined beam 120 and the support plate 310. The inclined beam 120 is fixed to the top end of the cantilever column 110 through the clamping member and the third locking portion 330, which enhances the stability of the inclined beam 120, provides a solid foundation for the subsequent installation work, and also ensures the safe fixation of the photovoltaic module 140. This stable connection method reduces the risk of the overall structure loosening or being damaged due to external forces and extends the service life of the photovoltaic support.

[0053] In a possible implementation, it further includes purlins 130; the purlins 130 are arranged between the inclined beams 120 and the photovoltaic modules 140, and the longitudinal direction of the purlins 130 is perpendicular to the longitudinal direction of the inclined beams 120; the main body of the purlins 130 is in a cuboid structure and has an opening on the side facing the photovoltaic modules 140, and the purlins 130 are connected to the inclined beams 120 through the fourth locking parts 131. As Figure 6 shown, the fourth locking parts 131 include fourth bolts 1311 and fourth nuts 1312. The purlins 130 are placed on the inclined beams 120 and the openings of the purlins 130 face away from the inclined beams 120. The fourth bolts 1311 sequentially pass through the purlins 130 and the inclined beams 120 and then are connected to the fourth nuts 1312. The combination of the fourth bolts 1311 and the fourth nuts 1312 provides a strong clamping force between the inclined beams 120 and the purlins 130. The fourth nuts 1312 are closely attached to the outer side walls of the inclined beams 120. By tightening the fourth nuts 1312, the fourth nuts 1312 move along the axial direction of the fourth bolts 1311 to clamp between the inclined beams 120 and the purlins 130, avoiding loosening of the fourth bolts 1311 under the action of vibration or external forces, and ensuring the stability and reliability of the overall structure.

[0054] Furthermore, there are two purlins 130, and the longitudinal directions of the two purlins 130 are parallel to each other. The two parallel purlins 130 jointly provide a stable support platform for the photovoltaic modules 140. They can evenly disperse the weight of the photovoltaic modules 140 and the external loads acting on the photovoltaic modules 140, ensuring the safety and stability of the photovoltaic modules 140.

[0055] In a possible implementation, as Figure 6 shown, it further includes a pressing block assembly 400; the photovoltaic modules 140 and the purlins 130 are connected through the pressing block assembly 400. It should be noted here that the pressing block assembly 400 includes a first pressing block 410, a second pressing block 420, and a fifth bolt 430. A limiting groove is formed on the top surface of the photovoltaic module 140, and the outer contour of the first pressing block 410 matches the limiting groove. The first pressing block 410 is embedded in the limiting groove. The second pressing block 420 is arranged in the cavity of the purlin 130, and a threaded hole matching the fifth bolt 430 is formed on the second pressing block 420. The fifth bolt 430 sequentially passes through the first pressing block 410 and the photovoltaic module 140 and then is connected to the threaded hole of the second pressing block 420. By turning the fifth bolt 430, the first pressing block 410 and the second pressing block 420 can move closer to or away from each other in the direction towards or away from the photovoltaic module 140 to clamp or loosen the purlin 120 and the photovoltaic module 140, thereby realizing the fixed installation and disassembly of the photovoltaic module 140 and the purlin 130. By setting the pressing block assembly 400, displacement or detachment of the photovoltaic module 140 caused by external forces is avoided, and the reliability of the connection between the photovoltaic module 140 and the purlin 130 is ensured.
