Description

Technical Field

[0001] This application relates to the field of photovoltaic power generation technology, and more specifically, to a mounting bracket. Background Technology

[0002] Mounting brackets are crucial components for securing photovoltaic (PV) modules to the roof. They consist of columns, inclined beams, and supports. One end of the inclined beam is hinged to the column, while the other end is elevated on another column via a support to accommodate the tilt angle of the PV modules. However, supports are typically designed as two parts: an upper support fixed to the inclined beam and a lower support fixed to the column, then hinged together. This type of support is not only structurally complex with numerous installation nodes, but also results in complex construction and high costs due to the large number of components. Utility Model Content

[0003] This application provides a mounting bracket to solve at least one of the above-mentioned technical problems.

[0004] The mounting bracket of this application embodiment is used for mounting photovoltaic modules, and the mounting bracket includes:

[0005] A bottom beam, which is used for installation on the roof;

[0006] The support includes a mounting base plate and a top wall. The mounting base plate is mounted on the bottom beam. The top wall is opposite to the bottom beam in the vertical direction, and the plane of the top wall forms a preset angle with the plane of the bottom beam.

[0007] An inclined beam, one end of which is connected to the bottom beam and the other end of which is fixed to the top wall, is used to fix the photovoltaic module.

[0008] The mounting bracket provided in this application uses a support to suspend one end of the inclined beam on the bottom beam. Compared with existing supports, the support structure in this application is simple, with fewer parts and fewer installation nodes, which helps to reduce installation difficulty and shorten installation time. At the same time, fewer parts also help to reduce production costs and processing difficulty, and facilitate material control.

[0009] In some embodiments, each of the bottom beams may be fitted with multiple inclined beams and supports at intervals along the length of the bottom beam for mounting multiple of the photovoltaic modules.

[0010] In this way, compared to each support column which can only fix one inclined beam or support, using the bottom beam to fix the inclined beam and support can fix multiple groups at once, thereby installing multiple photovoltaic modules. This helps to reduce the installation difficulty of photovoltaic modules and facilitates the centralized installation of photovoltaic modules.

[0011] In some embodiments, the bottom beam includes a load-bearing portion disposed at the connection between the bottom beam and the inclined beam.

[0012] Therefore, compared to setting the load at the bottom of the support column, placing the load directly on the load-bearing part can effectively reduce the height of the mounting bracket and improve its wind resistance.

[0013] In some embodiments, the mounting bracket further includes foot pads mounted on the side of the base beam away from the photovoltaic module.

[0014] Therefore, installing foot pads under the bottom beam can increase the friction between the mounting bracket and the roof, and improve the anti-slip ability of the mounting bracket.

[0015] In some embodiments, one end of the inclined beam is hinged to the bottom beam, and the top wall is also provided with a mounting hole. The other end of the inclined beam is connected to the inclined beam by a fastener passing through the mounting hole in the top wall.

[0016] Thus, the hinged connection allows for minor adjustments to the support structure, thereby overcoming thermal expansion and contraction or absorbing and dispersing external forces, which helps improve the overall stability of the structure and extend the service life of the support.

[0017] In some embodiments, both the inclined beam and the bottom beam are hollowed out along their length.

[0018] Thus, the hollow design can reduce the weight of the mounting bracket and also help reduce the production cost of the mounting bracket.

[0019] In some embodiments, the support further includes a first sidewall and a second sidewall, the first sidewall, the top wall and the second sidewall are connected sequentially, the first sidewall and the second sidewall are arranged perpendicular to the bottom beam, the sides of the first sidewall and the second sidewall away from the top wall are connected to the mounting base plate, and the height of the first sidewall is greater than the height of the second sidewall so that the top wall is inclined.

[0020] In this way, the first side wall, top wall, second side wall and mounting base plate form a hollow structure, which helps to reduce the weight of the mounting bracket and also helps to reduce the production cost of the mounting bracket.

[0021] In some embodiments, the support further includes a reinforcing wall, one side of which is connected to the first sidewall and the other side of which is connected to the second sidewall.

[0022] Therefore, setting up a reinforcing wall helps to improve the structural strength of the support and extend its service life.

[0023] In some embodiments, the mounting bracket further includes a wind deflector, which is disposed perpendicular to the bottom beam and fixed to the side of the support away from the connection between the inclined beam and the bottom beam.

[0024] In this way, the wind deflector can block the wind from the side of the photovoltaic module that is raised, thus preventing the photovoltaic module from being overturned by the wind.

[0025] Another embodiment of the photovoltaic installation system of this application includes the mounting bracket and photovoltaic module described in any of the above claims.

[0039] Mounting brackets are crucial components for securing photovoltaic (PV) modules to the roof. They consist of columns, inclined beams, and supports. One end of the inclined beam is hinged to the column, while the other end is elevated on another column via a support to accommodate the tilt angle of the PV modules. However, supports are typically designed as two parts: an upper support fixed to the inclined beam and a lower support fixed to the column, then hinged together. This type of support is not only structurally complex with numerous installation nodes, but also results in complex construction and high costs due to the large number of components.

[0040] Please see Figure 1 This application provides a photovoltaic installation system 1000, including a mounting bracket 100 and photovoltaic modules 200. The mounting bracket 100 includes a bottom beam 10, a support 20, and an inclined beam 30. The bottom beam 10 is used for mounting on a roof. The support 20 includes a mounting base plate 21 and a top wall 22. The mounting base plate 21 is mounted on the bottom beam 10, and the top wall 22 is opposite to the bottom beam 10 in the vertical direction, and the plane of the top wall 22 forms a preset angle with the plane of the bottom beam 10. One end of the inclined beam 30 is connected to the bottom beam 10, and the other end is fixed to the top wall 22. The inclined beam 30 is used to fix the photovoltaic modules 200.

[0041] The mounting bracket 100 provided in this application uses the support 20 to suspend one end of the inclined beam 30 on the bottom beam 10. Compared with the existing support 20, the support 20 in this application has a simple structure, fewer parts, and fewer installation nodes, which helps to reduce installation difficulty and shorten installation time. At the same time, fewer parts also help to reduce production costs and processing difficulty, and facilitate material control.

[0042] For details, please refer to Figures 1 to 3 In this embodiment of the application, installing each photovoltaic module 200 requires at least two sets of bottom beams 10, supports 20 and inclined beams 30. In this embodiment of the application, installing each photovoltaic module 200 requires two sets of bottom beams 10, supports 20 and inclined beams 30. The two bottom beams 10 are spaced apart at the bottom of the photovoltaic module 200, and the two inclined beams 30 are located on the back of the photovoltaic module 200 and connected to the photovoltaic module 200.

[0043] Furthermore, one end of the inclined beam 30 is connected to the bottom beam 10, and the other end is elevated by the support 20, so that the bottom beam 10, inclined beam 30, and support 20 form a triangular structure. Thus, the photovoltaic module 200 support structure forms a triangular structure. A triangular structure is a very stable structural form mechanically, maintaining a stable support effect and ensuring the safe operation of the photovoltaic module 200. The triangular structure also distributes weight evenly across all support points, thereby improving the overall load-bearing capacity. In addition, the triangular structure allows for easy adjustment of the angle and height of the photovoltaic module 200 according to actual needs, achieving optimal power generation performance.

[0044] In this embodiment, the preset tilt angle is 10°, meaning the installation tilt angle of the photovoltaic module 200 (i.e., the angle between the photovoltaic module 200 and the horizontal plane) is 10°. From a power generation efficiency perspective, a photovoltaic module 200 with a 10° tilt angle can better receive solar radiation, especially in spring and autumn in most regions and in areas with moderate latitudes. This angle helps the photovoltaic module 200 capture more direct sunlight, thereby improving power generation efficiency. Furthermore, an appropriate tilt angle can reduce light reflection loss, allowing more solar energy to be absorbed by the photovoltaic module 200 and converted into electrical energy. On the other hand, for stability and safety considerations, a 10° tilt angle not only helps the photovoltaic module 200 remain stable in strong winds, reducing the risk of damage due to excessive wind force, but also facilitates rapid rainwater drainage, preventing water accumulation from damaging the photovoltaic module 200, and also helps reduce safety hazards caused by water accumulation.

[0045] In other embodiments, the preset included angle can also be set to other angles, which can be selected according to actual needs, and will not be elaborated on here.

[0046] In this embodiment, the support 20 is a one-piece structure manufactured in one piece, which helps reduce the processing difficulty and production cost of the support 20. The support 20 is made of aluminum alloy. Using aluminum alloy to produce the support 20 is convenient for manufacturing and processing, and it helps to reduce the weight of the support 20 while ensuring its strength and improving its corrosion resistance. Furthermore, the bottom beam 10 and the inclined beam 30 can also be made of aluminum alloy. In other embodiments, the support 20, bottom beam 10, and inclined beam 30 can also be made of other materials. The specific materials can be selected according to the actual weight and strength requirements, which will not be elaborated on here.

[0047] Please see Figure 2 In some embodiments, each bottom beam 10 may be equipped with multiple inclined beams 30 and supports 20 at intervals along its length for mounting multiple photovoltaic modules 200.

[0048] In this way, compared to each support column which can only fix one inclined beam 30 or support 20, multiple sets can be fixed at once by using the bottom beam 10 to fix the inclined beam 30 and support 20, thereby installing multiple photovoltaic modules 200. This helps to reduce the installation difficulty of photovoltaic modules 200 and facilitates the centralized installation of photovoltaic modules 200.

[0049] Specifically, in this embodiment, the bottom beams 10 are used in pairs, and several sets of inclined beams 30 and supports 20 can be installed on each pair of bottom beams 10. Each set of inclined beams 30 and supports 20 can install one photovoltaic module 200. It should be noted that a certain gap should be formed between two adjacent photovoltaic modules 200 to avoid obstruction between photovoltaic modules 200 and affecting power generation efficiency.

[0050] In this embodiment, the bottom beam 10 has multiple through holes, which are evenly spaced along the length of the bottom beam 10. The mounting bracket 100 also includes fasteners, through which the bottom beam 10 can be connected to the bracket or fixed to the roof.

[0051] Furthermore, the through-hole is a long slot, which allows for some movement of the fastener within the slot. This provides the fixed component with some adjustment leeway when subjected to external forces, such as temperature changes or structural deformation, thereby reducing the accumulation of stress and deformation. This not only improves the overall stability of the system but also helps extend the service life of the components. In addition, the long slot can accommodate bolts or screws of different sizes and shapes, making the installation process more flexible and convenient.

[0052] In this embodiment, the bottom beam 10 is an integrally formed long strip structure, and its specific length can be cut and used according to the actual installation needs of the photovoltaic module 200.

[0053] In some embodiments, the bottom beam 10 includes a load-bearing portion 11, which is disposed at the connection between the bottom beam 10 and the inclined beam 30.

[0054] Therefore, compared to setting the load at the bottom of the support column, directly pressing the load onto the load-bearing part 11 can effectively reduce the height of the mounting bracket 100 and improve the wind resistance of the mounting bracket 100.

[0055] Specifically, in this embodiment, the load-bearing part 11 is used to apply a load. The load-bearing part 11 can be located at the connection between the bottom beam 10 and the inclined beam 30, and at the end away from the support 20. Alternatively, the load-bearing part 11 can be located at the connection between the bottom beam 10 and the support 20, and at the end away from the inclined beam 30. In use, a heavy object can be placed on top of the load-bearing part 11 or cement can be poured on top of it. Thus, compared to the conventional approach of pouring cement counterweights under the support pillars, which makes the height of the entire mounting bracket 100 about one meter, in this embodiment, the counterweights are placed above the load-bearing part 11, effectively reducing the height of the entire mounting bracket 100. The highest point of the mounting bracket 100 is about 0.40 meters, which is usually lower than the height of the parapet wall. This allows the parapet wall to withstand most of the wind pressure when the photovoltaic module 200 is installed on the roof, reducing the impact of wind pressure. Combined with the cement counterweights, the entire photovoltaic module 200 and mounting bracket 100 have strong wind resistance, effectively increasing the reliability of the mounting bracket 100 and helping to extend the service life of the photovoltaic module 200 and mounting bracket 100.

[0056] In other embodiments, the bottom beam 10 may not be fixed with a counterweight, and it can also be fixed to the roof using fasteners with through holes. It should be noted that this fixing method requires drilling holes in the roof; during installation, care should be taken to ensure the drilling depth is correct to avoid damaging the roof and causing leaks.

[0057] In some embodiments, the mounting bracket 100 further includes foot pads 12, which are mounted on the side of the base beam 10 away from the photovoltaic module 200.

[0058] Thus, installing foot pads 12 under the bottom beam 10 can increase the friction between the mounting bracket 100 and the roof, thereby improving the anti-slip capability of the mounting bracket 100.

[0059] Specifically, in this embodiment, the foot pads 12 are disposed between the roof and the bottom beam 10. There are multiple foot pads 12, and the foot pads 12 are evenly spaced along the length of the bottom beam 10.

[0060] In this embodiment, the foot pad 12 can be detachably connected to the base beam 10 via fasteners. In other embodiments, the foot pad 12 and the base beam 10 can also be connected by adhesive, snap-fit, or other methods. The specific connection method can be selected according to actual needs, and will not be elaborated on here.

[0061] The material of the foot pad 12 can be rubber, plastic, metal, etc. In this embodiment, the foot pad 12 is made of rubber. Rubber has excellent wear resistance and can withstand long-term use, so the service life of the rubber foot pad 12 is relatively long. The rubber foot pad 12 also has high elasticity with reversible deformation, and can return to its original shape after being subjected to external force, thereby maintaining its support performance. At the same time, the rubber foot pad 12 also has certain functions such as anti-collision, shock absorption, temperature resistance, and noise reduction.

[0062] In this embodiment, the surface of the foot pad 12 that contacts the roof can also be provided with anti-slip patterns, which helps to further improve the anti-slip capability of the mounting bracket 100.

[0063] Please see Figure 2 In some embodiments, one end of the inclined beam 30 is hinged to the bottom beam 10, and the top wall 22 is also provided with a mounting hole 221. The other end of the inclined beam 30 is connected to the inclined beam 30 through a fastener passing through the mounting hole 221 of the top wall 22.

[0064] Thus, the hinged connection allows for minor adjustments to the support structure, thereby overcoming thermal expansion and contraction, or absorbing and dispersing external forces, which helps improve the overall structural stability and extend the service life of the support.

[0065] Specifically, in the embodiments of this application, the inclined beams 30 are used in pairs, and a photovoltaic module 200 can be installed on each pair of inclined beams 30.

[0066] In this embodiment, the inclined beam 30 has multiple through holes, which are evenly spaced along the length of the inclined beam 30. The mounting bracket 100 also includes fasteners, through which the inclined beam 30 can pass to the fasteners and connect to the bracket.

[0067] In this embodiment, the top wall 22 is further provided with mounting holes 221, and the other end of the inclined beam 30 is connected to the inclined beam 30 through fasteners passing through the mounting holes 221 in the top wall 22 and the through holes in the inclined beam 30. Furthermore, there are two mounting holes 221, which are spaced apart.

[0068] Furthermore, the through-hole is a long slot, which allows for some movement of the fastener within the slot. This provides the fixed component with some adjustment leeway when subjected to external forces, such as temperature changes or structural deformation, thereby reducing the accumulation of stress and deformation. This not only improves the overall stability of the system but also helps extend the service life of the components. In addition, the long slot can accommodate bolts or screws of different sizes and shapes, making the installation process more flexible and convenient.

[0069] In this embodiment, the inclined beam 30 is an integrally formed long strip structure, and its specific length can be cut and used according to the actual installation needs of the photovoltaic module 200.

[0070] In this embodiment, a hinge seat 13 is detachably connected to the bottom beam 10 by fasteners. The hinge seat 13 includes a first wall and a second wall spaced apart. Both the first wall and the second wall are provided with a first shaft hole. The inclined beam 30 is installed between the first wall and the second wall. The end of the inclined beam 30 is provided with a second shaft hole. The rotating shaft passes through the first shaft hole and the second shaft hole to realize the hinged connection between the inclined beam 30 and the bottom beam 10.

[0071] Please see Figure 4 and Figure 5 In some embodiments, both the inclined beam 30 and the bottom beam 10 are hollowed out along the length direction.

[0072] Thus, the hollow design can reduce the weight of the mounting bracket 100, and at the same time help to reduce the production cost of the mounting bracket 100.

[0073] Specifically, the openwork design enhances the aesthetics of the inclined beam 30 and the bottom beam 10, while also reducing their weight, making them lighter and easier to transport. It is important to note that when the openwork section needs to bear a large load, additional reinforcement measures are required to ensure its stability. During use and maintenance, care should be taken to protect the openwork section from impacts or scratches to extend its service life.

[0074] Furthermore, the inclined beam 30 and the bottom beam 10 are hollowed out along their length.

[0075] Please see Figure 3 In some embodiments, the support further includes a first sidewall 23 and a second sidewall 24. The first sidewall, the top wall 22, and the second sidewall 24 are connected in sequence. The first sidewall 23 and the second sidewall 24 are arranged perpendicular to the bottom beam 10. The sides of the first sidewall 23 and the second sidewall 24 away from the top wall 22 are connected to the mounting base plate 21. The height of the first sidewall 23 is greater than the height of the second sidewall 24 so that the top wall 22 is inclined.

[0076] Thus, the first side wall 23, the top wall 22, the second side wall 24 and the mounting base plate 21 form a hollow structure, which helps to reduce the weight of the mounting bracket 100 and also helps to reduce the production cost of the mounting bracket 100.

[0077] Specifically, in this embodiment, the mounting base plate 21, the first side wall 23, the top wall 22, and the second side wall 24 are all plate-shaped structures, wherein the first side wall 23 and the second side wall 24 are perpendicular to the mounting base plate 21, and the top wall 22 is arranged opposite to the mounting base plate 21.

[0078] In this embodiment, both mounting holes 221 are located between the first sidewall 23 and the second sidewall 24, which helps to improve the firmness of the connection between the support 20 and the inclined beam 30.

[0079] In this embodiment, the mounting base plate 21 is further provided with fixing holes, and the support 20 is connected to the bottom beam 10 by fasteners passing through the fixing holes of the mounting base plate 21. Furthermore, there are two fixing holes, one of which is located on the side of the first sidewall 23 away from the second sidewall 24, and the other is located on the side of the second sidewall 24 away from the first sidewall 23. This helps to improve the firmness of the connection between the support 20 and the bottom beam 10.

[0080] In some embodiments, the support 20 further includes a reinforcing wall 25, one side of which is connected to the first sidewall 23 and the other side of which is connected to the second sidewall 24.

[0081] Thus, the reinforcement wall 25 helps to improve the structural strength of the support 20 and extend its service life.

[0082] Specifically, in this embodiment, the reinforcing wall 25 is a plate-like structure, and the reinforcing wall 25 is disposed between the first side wall 23 and the second side wall 24.

[0083] Furthermore, there are multiple reinforcing walls 25, which are spaced apart. In this embodiment, there are two reinforcing walls 25, which are spaced apart, and the two reinforcing walls 25 are spaced apart from the top wall 22 and the mounting base plate 21.

[0084] In this embodiment, the two reinforcing walls 25 are arranged parallel to the mounting base plate 21. In some embodiments, the reinforcing walls 25 may also be set at other angles.

[0085] Please see Figure 1 In some embodiments, the mounting bracket 100 further includes a wind deflector 40, which is arranged perpendicular to the bottom beam 10 and fixed to the side of the support 20 away from the connection between the inclined beam 30 and the bottom beam 10.

[0086] In this way, the wind deflector 40 can block the wind from the side of the photovoltaic module 200 that is raised, thus preventing the photovoltaic module 200 from being overturned by the wind.

[0087] For details, please refer to Figure 1 and Figure 3 In this embodiment of the application, the mounting bracket 100 also includes a wind baffle 40, which is arranged perpendicular to the bottom beam 10 and is fixed on the surface of the support 20 away from the connection between the inclined beam 30 and the bottom beam 10.

[0088] In this embodiment, the wind deflector 40 is mounted on the first sidewall 23, which has mounting holes. The wind deflector 40 is detachably mounted on the first sidewall 23 through these mounting holes. The width of the wind deflector 40 is slightly smaller than the length of the first sidewall 23. Compared to mounting it on the second sidewall 24, mounting the wind deflector 40 on the first sidewall 23 allows the bracket to provide more support for the wind deflector 40, which helps improve its structural strength, stability, and service life.

[0089] In some embodiments, the wind deflector 40 may also be mounted on the second sidewall 24. In this case, the second sidewall 24 is provided with a baffle mounting hole, and the wind deflector 40 is detachably mounted on the second sidewall 24 through the baffle mounting hole. The width of the wind deflector 40 is slightly smaller than the length of the second sidewall 24.

[0090] Please see Figure 1 and Figure 6 In some embodiments, each wind deflector 40 is connected to a plurality of supports 20.

[0091] In this way, the wind deflector 40 can improve the structural strength of the mounting bracket 100, and at the same time facilitate the centralized installation of the photovoltaic modules 200.

[0092] Specifically, in this embodiment, when multiple photovoltaic modules 200 are installed together on the roof, the same windbreak plate 40 can connect to the supports 20 of all photovoltaic modules 200 installed in the same row, thereby integrating all the mounting brackets 100 and improving the structural strength of all the mounting brackets 100. In other embodiments, the same windbreak plate 40 can connect to two supports 20 used to install and fix the same photovoltaic module 200, thereby improving the structural strength of a group of mounting brackets 100.
