Description

Technical Field

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

[0002] Inverters are widely used as important conversion equipment. When installing inverters on roofs and other places, a stable and reliable bracket structure is required to ensure their normal operation and safety. Traditional inverter brackets often lack effective rain protection measures, which makes the inverter directly exposed to the outdoor environment. When it rains, rain may directly fall on the inverter, causing the equipment to get damp, short-circuit or even be damaged, seriously affecting the normal operation and service life of the inverter.

[0003] Therefore, how to provide rain protection for the inverter and reduce the direct erosion of rain on the inverter 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 roof photovoltaic inverter bracket, comprising: two mounting bases, two support columns, a crossbeam and a rain cover;

[0005] The length directions of the two support columns are parallel to each other, and the bottom ends of the two support columns are respectively connected to two mounting bases through two fixing components, and the mounting bases are suitable for providing stable support for the support columns;

[0006] The fixing assembly includes two U-shaped bolts arranged opposite to each other, a fixing base plate and four nuts; the opening ends of the two U-shaped bolts face the side where the support column is located, the mounting base is covered on the outside of the two U-shaped bolts, and both ends of the two U-shaped bolts protrude from the mounting base;

[0007] The support column is arranged on the top surface of the fixed bottom plate, the bottom surface of the fixed bottom plate is arranged on the top surface of the mounting base, and both ends of the two U-shaped bolts penetrate the fixed bottom plate, and the four nuts are respectively sleeved on both ends of the two U-shaped bolts and tightly fit with the side of the fixed bottom plate away from the mounting base, which is suitable for locking the fixed bottom plate on the mounting base;

[0008] The crossbeam is arranged between two supporting columns and is suitable for providing a mounting position for the inverter;

[0009] Rain covers are provided on the top of the two support columns.

[0010] In a possible implementation manner, the length direction of the cross beam and the length direction of the support column are perpendicular to each other.

[0011] In a possible implementation, more than two cross beams are provided; the more than two cross beams are arranged between two support columns and the length directions of the more than two cross beams are parallel to each other.

[0012] In a possible implementation, a fixing beam is provided on one side of the rain cover connected to the supporting column, and the fixing beam is arranged on the top surfaces of the two supporting columns.

[0013] In a possible implementation, it also includes two diagonal braces; the two diagonal braces are relatively arranged on both sides of the rain cover, and the two ends of the diagonal braces are respectively connected to the support column and the rain cover, which is suitable for providing support for the rain cover.

[0014] In a possible implementation, a first preset angle is provided between the length direction of the diagonal brace and the length direction of the support column, and a second preset angle is provided between the length direction of the diagonal brace and the length direction of the rain cover.

[0015] Beneficial effects of this application

[0016] By setting up a rain cover, the rain cover provides rain protection for the inverter, reduces the damage to the inverter caused by rain, and ensures the normal operation of the inverter. At the same time, the rain cover can prevent rain from directly wetting the support column, avoiding the support column from rusting due to long-term contact with water, thereby extending the service life of the bracket.

[0034] A roof-mounted photovoltaic inverter bracket, as Figures 1 to 7 shown, includes: two mounting bases 100, two support columns 110, a cross beam 120 and a rain shield 400; the longitudinal directions of the two support columns 110 are parallel to each other, and the bottom ends of the two support columns 110 are respectively connected to the two mounting bases 100 through two fixing components 300, and the mounting bases 100 are suitable for providing stable support for the support columns 110; each fixing component 300 includes two oppositely arranged U-shaped bolts 310, a fixing bottom plate 320 and four nuts 330; the open ends of the two U-shaped bolts 310 face the side where the support column 110 is located, the mounting base 100 is wrapped outside the two U-shaped bolts 310, and both ends of the two U-shaped bolts 310 protrude from the mounting base 100; the support column 110 is arranged on the top surface of the fixing bottom plate 320, the bottom surface of the fixing bottom plate 320 is arranged on the top surface of the mounting base 100, and both ends of the two U-shaped bolts 310 penetrate through the fixing bottom plate 320, and the four nuts 330 are respectively sleeved on both ends of the two U-shaped bolts 310 and are closely attached to the side of the fixing bottom plate 320 away from the mounting base 100, and are suitable for locking the fixing bottom plate 320 on the mounting base 100; the cross beam 120 is arranged between the two support columns 110 and is suitable for providing a mounting position for the inverter 500; a rain shield 400 is provided at the top of the two support columns 110.

[0035] It should be noted here that, as Figure 1 、 Figure 2As shown, the installation base 100 is fixedly installed on the roof of the house, avoiding damage to the roof surface such as scratches and perforations. At the same time, the installation base 100 provides stable support for the support columns 110, preventing the support columns 110 from toppling or shaking due to external forces and ensuring the stability of the overall structure. The two parallel support columns 110 can evenly share the vertical load, improving the load-bearing capacity of the support columns 110. The fixing component 300 firmly fixes the support columns 110 on the installation base 100, ensuring that the support columns 110 will not shake or shift. At the same time, the fixing component 300 also plays a role in transmitting and dispersing the load to a certain extent, enabling the force borne by the support columns 110 to be evenly transmitted to the installation base 100. Both ends of the cross beam 120 are fixedly connected to the two support columns 110 respectively. The cross beam 120 is suitable for providing an installation position for the inverter 500. At the same time, the design of the cross beam 120 enables the overall structure to withstand greater lateral forces, enhancing the stability and load-bearing capacity of the overall structure. The rain shield 400 is arranged on the tops of the two support columns 110, suitable for providing rain protection for the inverter 500 below, reducing damage to the inverter 500 caused by rain, ensuring the normal operation of the inverter 500. At the same time, the rain shield 400 can prevent rain from directly wetting the support columns 110, avoiding problems such as rusting of the support columns 110 due to long-term exposure to water and extending the service life of the bracket.

[0036] As Figures 1 to 4 shown, two oppositely arranged U-shaped bolts 310 are embedded in the installation base 100, making the two U-shaped bolts 310 firmly connected to the installation base 100. Compared with simply installing the support columns 110 on the roof of the house, the embedded method enables the support columns 110 to withstand greater tensile force and stress, effectively ensuring the stability of the overall structure. The two ends of the U-shaped bolts 310 protrude from the installation base 100 to facilitate the subsequent installation of the fixing base plate 320 and the nuts 330. The bottom surface of the fixing base plate 320 is placed on the top surface of the installation base 100. The fixing base plate 320 is suitable for expanding the contact area between the support columns 110 and the installation base 100, making the support columns 110 more stable on the installation base 100 and reducing shaking or displacement caused by external forces. Four nuts 330 cooperate with the two U-shaped bolts to lock the fixing base plate 320 on the installation base 100, ensuring a tight connection between the fixing base plate 320 and the installation base 100 and preventing the support columns 110 from loosening.

[0037] In a possible implementation manner, as Figure 1 、 Figure 3As shown, the main body of the fixed base plate 320 is a rectangular plate-like structure. The rectangular plate-like structure of the fixed base plate 320 has good stability, can evenly disperse the load from the support column 110, and reduce stress concentration. The four corners of the fixed base plate 320 are provided with mounting holes 321 matching the U-shaped bolts 310. Both ends of the two U-shaped bolts 310 are passed through the mounting holes 321 of the fixed base plate 320. Four nuts 330 are respectively sleeved on both ends of the two U-shaped bolts 310. By tightening the nuts 330, the nuts 330 and the side of the fixed base plate 320 away from the mounting base 100 are tightly fitted to provide sufficient clamping force, thereby fixing the fixed base plate 320 on the mounting base 100.

[0038] Furthermore, the U-shaped bolt 310 and the nut 330 are both M8U-type bolts and nuts 330 in the prior art.

[0039] Furthermore, the main body of the mounting base 100 is a cube structure, and the mounting base 100 is a concrete pier cast by concrete. The mounting base 100 cast by concrete can effectively isolate the direct contact between the photovoltaic bracket and the roof, and reduce the damage to the roof caused by the installation of the bracket. At the same time, the mounting base 100 cast by concrete can provide good wind and earthquake resistance due to its weight and firmness, thereby ensuring the stability of the overall structure.

[0040] In a possible implementation, the fixed bottom plate 320 is fixedly connected to the support column 110, and the plane where the fixed bottom plate 320 is located is perpendicular to the length direction of the support column 110. It should be noted here that the fixed bottom plate 320 is fixedly connected to the support column 110 by welding, and the welding connection makes the connection between the fixed bottom plate 320 and the support column 110 more stable and reliable, reducing the possibility of the support column 110 toppling due to loose connection or failure. The vertical connection between the fixed bottom plate 320 and the support column 110 provides a strong vertical support for the entire structure. This support method can effectively resist the force from the vertical direction and ensure the stability and safety of the structure.

[0041] Furthermore, the two support columns 110 are both made of angle steel, and the openings of the two support columns 110 are arranged in opposite directions. The two ends of the beam 120 are arranged in the openings of the two support columns 110. The relative openings make the support columns 110 more evenly stressed when bearing the pressure from the beam 120 and the inverter 500 on the beam 120, thereby improving the overall stability.

[0042] In one possible implementation, Figure 1 , Figure 2As shown, the longitudinal direction of the cross beam 120 is perpendicular to the longitudinal direction of the support column 110. It should be noted here that the structure where the cross beam 120 intersects the support column 110 perpendicularly can provide additional stiffness and stability, thereby effectively transferring the weight and lateral force of the inverter 500 to the support column 110, and then being transferred by the support column 110 to the installation base 100, thus ensuring the stability of the overall structure.

[0043] Furthermore, there are more than two cross beams 120; more than two cross beams 120 are all arranged between two support columns 110 and the longitudinal directions of the two cross beams 120 are parallel to each other. It should be noted here that more than two cross beams 120 are all made of angle steel, and both ends of each cross beam 120 are fixedly connected to the two support columns 110 by welding respectively. More than two cross beams 120 share the weight of the inverter 500 together, effectively avoiding the deformation of a single cross beam 120 due to excessive pressure, and ensuring the stability of the overall structure.

[0044] In a possible implementation manner, a fixed beam 410 is provided on one side of the rain shield 400 connecting the support column 110, and the fixed beam 410 is arranged on the top surfaces of the two support columns 110. It should be noted here that as Figure 6 shown, the main body of the rain shield 400 is in a rectangular plate-like structure, as Figure 1 shown, one side of the rain shield 400 is located between the fixed beam 410 and the support column 110, and a third preset angle γ is provided between the plane where the rain shield 400 is located and the longitudinal direction of the support column 110. The support column 110 and the fixed beam 410 form a stable frame structure, which is suitable for providing a support foundation for the rain shield 400. The setting of the fixed beam 410 can effectively resist external forces such as wind loads and snow loads, ensuring the stability of the rain shield 400 under harsh weather conditions. Among them, the value range of the third preset angle γ is: 80 degrees - 90 degrees. Preferably, the value of the third preset angle γ is: 85 degrees.

[0045] Furthermore, the fixed beam 410 is made of angle steel, the opening of the fixed beam 410 faces the support column 110, and the tops of the two support columns 110 and the rain shield 400 are all located within the opening of the fixed beam 410, that is, the two top corners on the side of the rain shield 400 close to the support column 110 are buckled on the tops of the two support columns 110, and then the fixed beam 410 is buckled on the side of the rain shield 400 and fixedly connected to the two support columns 110. Among them, the fixed beam 410, the rain shield 400 and the support column 110 are all fixedly connected by welding. The two support columns 110 and the fixed beam 410 enclose a "Π" - shaped structure, enabling the rain shield 400 to effectively transfer the load to the support column 110 when subjected to external forces.

[0046] In a possible implementation manner, asFigure 1 , Figure 2 , Figure 7 As shown in Figure 7 , it further includes two diagonal braces 420; the two diagonal braces 420 are oppositely arranged on both sides of the rain shield 400, and both ends of the diagonal braces 420 are respectively connected to the support column 110 and the rain shield 400, which is suitable for providing support for the rain shield 400. It should be noted here that the diagonal braces 420 are made of angle steel. One end of the diagonal brace 420 is fixedly connected to the outer side wall of the support column 110 by welding, and the other end of the diagonal brace 420 is fixedly connected to the bottom of the rain shield 400 by welding. The symmetrically arranged diagonal braces 420 improve the lateral stiffness of the rain shield 400, enabling the rain shield 400 to maintain the stability of the structure when facing lateral loads such as wind pressure. At the same time, the diagonal braces 420 can disperse part of the loads and stresses received by the rain shield 400 to the support column 110, thereby reducing the stress burden on the rain shield 400 itself and improving the load-bearing capacity of the entire structure.

[0047] In a possible implementation manner, as shown in Figure 8 , there is a first preset angle α between the longitudinal direction of the diagonal brace 420 and the longitudinal direction of the support column 110, and a second preset angle β between the longitudinal direction of the diagonal brace 420 and the longitudinal direction of the rain shield 400. It should be noted here that the design of the first preset angle α can ensure that the diagonal brace 420 can fully exert its performance when stressed, avoiding deformation of the diagonal brace 420 caused by stress concentration. At the same time, it also helps to more evenly transfer the loads of the rain shield 400 to the support column 110, reducing the direct impact of the wind on the rain shield 400 and improving the overall load-bearing capacity of the structure; by setting the second preset angle β, the influence of the wind pressure on the rain shield 400 is reduced. At the same time, the second angle helps to prevent rainwater from accumulating on the surface of the rain shield 400, reducing the scouring and erosion of the structure by rainwater and extending the service life of the structure.

[0048] Furthermore, the value range of the first preset angle α is: 40 degrees < α < 50 degrees, and the value range of the second preset angle β is: 50 degrees < β < 60 degrees.

[0049] Preferably, the value of the first preset angle α is: 45 degrees, and the value of the second preset angle β is 50 degrees.
