Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic component technology, and relates to a photovoltaic bracket, specifically a planar FRP photovoltaic bracket. Background Technology

[0002] Distributed photovoltaic (PV) power generation systems refer to PV power generation facilities built on or near user sites. Their operation is primarily based on user-side self-consumption, with surplus electricity fed into the grid, and characterized by balancing and regulating the distribution network system. Distributed PV systems are typically installed on rooftops of urban buildings, in enterprises and institutions, and in commercial buildings, with installed capacities generally within several thousand kilowatts. Their power generation can be connected to the distribution network via low-voltage lines, complementing the public grid and improving its reliability and stability. Furthermore, distributed PV power generation advocates the principles of local generation, local grid connection, local conversion, and local use, which not only increases the power generation of PV power plants of the same scale but also effectively solves the problems of power loss during voltage boosting and long-distance transmission. Compared to centralized PV power generation, distributed PV power generation is characterized by its small scale and decentralization, making it suitable for densely populated areas such as cities and rural areas. Its operation and maintenance management is relatively simple and has lower technical requirements.

[0003] Distributed photovoltaic (PV) systems, as a clean, efficient, and flexible energy utilization method, have broad development prospects and application potential. Distributed PV mainly includes two parts: residential PV and industrial / commercial PV. Residential PV is mainly aimed at household users and is relatively small in scale; while industrial / commercial distributed PV is aimed at industrial and commercial users and is relatively large in scale, usually installed on the roofs of factories, commercial buildings, etc.

[0004] Solar photovoltaic (PV) mounting systems are specialized supports designed for placing, installing, and securing solar panels in a solar photovoltaic (PV) power generation system. Distributed PV mounting systems are typically installed on rooftops or balcony railings, and are usually made of aluminum alloy, carbon steel, or stainless steel. These materials are relatively heavy, requiring a certain load-bearing capacity from the main building during design and installation. Furthermore, the manufacturing process for these materials is complex, resulting in poor design flexibility and high costs.

[0005] Chinese utility model patent application number 202322424733.5 discloses a photovoltaic (PV) bracket, specifically relating to the PV field. The bracket includes a PV bracket with a PV panel mounted on its top. An internal spline is rotatably connected to the top of the bracket, and an external spline is inserted into the internal spline. One end of the external spline is fixedly connected to a threaded rod, which is rotatably connected inside the PV bracket. An insert rod is inserted into the threaded rod, and a pull ring is hinged to one side of the insert rod. A slider is threadedly connected to the outer wall of the threaded rod, and the slider is slidably connected inside the PV bracket. A push rod is fixedly connected to the outer wall of the slider. This application utilizes a threaded rod and a fixing plate. First, the PV panel is placed on the PV bracket. Then, a portion of the insert rod is pulled out and rotated. Depending on the direction of rotation of the insert rod, the fixing plate either secures or stops securing the PV panel, thus achieving rapid installation or removal of the PV panel. However, this PV bracket has a complex structure and high cost, making it unsuitable for installation in flat locations (such as ground or flat roofs). Summary of the Invention

[0006] To address the aforementioned issues, the purpose of this invention is to provide a planar FRP photovoltaic bracket that reduces costs, improves the cost-effectiveness of photovoltaic brackets, and facilitates installation.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a planar FRP photovoltaic bracket, characterized in that: it includes at least two sets of support connection units arranged parallel to each other and spaced apart.

[0008] Each set of the support connection units includes multiple support seats that are spaced apart and mounted on the base, and a support beam mounted on the multiple support seats for mounting photovoltaic panels;

[0009] The supporting beam is parallel to the base, or the angle formed between the supporting beam and the base is an acute angle;

[0010] The supporting beam is made of glass fiber reinforced plastic.

[0011] Optimally, when the angle formed between the support beam and the base is an acute angle, each set of support connection units further includes a first support rod connecting the upper end of the support beam and the corresponding support seat, wherein the angle formed between the first support rod and the support beam is 10~160°.

[0012] Furthermore, the included angle between the first support rod and the support beam is 50~120°.

[0013] Furthermore, it also includes connecting rods or connecting rod groups that connect two adjacent first support rods.

[0014] Ideally, at least the supporting beam includes a first connecting plate and a second connecting plate that are parallel to each other and spaced apart, and a third connecting plate formed on the edge of the first connecting plate and the edge of the second connecting plate to connect the first connecting plate and the second connecting plate, the third connecting plate being perpendicular to the first connecting plate or the second connecting plate, and the photovoltaic panel being mounted on the outer surface of the third connecting plate.

[0015] Furthermore, if the width of the first connecting plate is D and the width of the second connecting plate is d, then D > d.

[0016] Furthermore, the support includes a base plate for mounting on a substrate and a support plate formed on and perpendicular to the base plate, the support plate being connected to the first connecting plate.

[0017] According to one embodiment of the present invention, the upper part of the support plate has two inclined surfaces extending upwards and in opposite directions.

[0018] Due to the application of the above technical solutions, this utility model has the following advantages compared with the prior art: The planar FRP photovoltaic bracket of this utility model, by using a support base and a support beam for cooperation, can realize the installation of photovoltaic panels at different angles, with a simple, stable and durable structure; moreover, the glass fiber reinforced plastic is lightweight and cost-effective.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0027] This embodiment provides a planar FRP photovoltaic mounting system, such as... Figure 1 As shown, it includes at least two sets of support connection units arranged parallel to each other and spaced apart. These support connection units are typically aligned to cooperate with each other. The specific number of support connection units can be adjusted according to the size of the photovoltaic panel b; in this embodiment, there are two sets.

[0028] Each support connection unit includes multiple support seats 11 spaced apart on the base a and support beams 12 mounted on the support seats 11 for mounting photovoltaic panels b. The base a can be a generally horizontal location such as the ground or roof; the multiple support seats 11 are usually in the same horizontal plane to mount the support beams 12 (at this time, the support beams 12 are parallel to the base a), and the specific number of support seats 11 can be adjusted according to the size of the photovoltaic panels b, which is two in this embodiment. The support beams 12 are made of glass fiber reinforced plastic (FRP), which is highly designable, easy to install, has high specific strength, is lightweight, effectively reduces the load-bearing pressure on the main structure, and also has the advantages of corrosion resistance and good stability.

[0029] In this embodiment, the supporting beam 12 includes a first connecting plate 121, a second connecting plate 122, and a third connecting plate 123; the first connecting plate 121 and the second connecting plate 122 are parallel to each other and spaced apart and aligned; the third connecting plate 123 is formed on the edges of the first connecting plate 121 and the second connecting plate 122 to connect the first connecting plate 121 and the second connecting plate 122 (these are usually integrally formed, the same below), such that the first connecting plate 121 and the second connecting plate 122 are on the same side of the third connecting plate 123, and the third connecting plate 123 is perpendicular to the first connecting plate 121 or the second connecting plate 122; Figure 4 As shown, the width of the first connecting plate 121 is defined as D, and the width of the second connecting plate 122 is defined as d. Then D > d, which can improve the overall strength of the supporting beam 12 and increase the load-bearing capacity of the photovoltaic panel b. In use, the photovoltaic panel b is installed on the outer surface of the third connecting plate 123 (i.e., the surface away from the first connecting plate 121 or the second connecting plate 122).

[0030] In this embodiment, the support base 11 includes a base plate 112 for mounting on the base a and a support plate 111 formed on and perpendicular to the base plate 112. The support plate 111 is typically located at the edge of the base plate 112, making the cross-section of the support base 11 angular (right-angled). Here, the surface of the support plate 111 facing away from the base plate 112 is defined as its outer surface, and the surface facing the base plate 112 is defined as its inner surface; the surface of the first connecting plate 121 facing the second connecting plate 122 is defined as its inner surface, and the surface facing away from the second connecting plate 122 is defined as its outer surface. Thus, when the support plate 111 is connected to the first connecting plate 121, the inner surface of the support plate 111 contacts the outer surface of the first connecting plate 121 (e.g., ...). Figure 2 (As shown). The upper part of the support plate 111 has two upwardly extending inclined surfaces 1111, as shown. Figure 3 As shown, the upper dimension of the support plate 111 gradually decreases in the upward direction, which helps to reduce the use of raw materials and reduce weight. Typically, multiple mounting holes are made in the base plate 112, and the support base 11 is mounted on the base a using connectors 113 installed in these mounting holes; the connectors 113 can be conventional screws, bolts, expansion bolts, or other parts.

[0031] At least one first connecting hole 124 is provided at both ends of the first connecting plate 121. The number of first connecting holes 124 at each end can be determined comprehensively based on factors such as connection strength and space requirements. In this embodiment, two holes are provided at each end. In addition, when the number of support bases 11 exceeds two, the middle part of the first connecting plate 121 is usually also provided with a corresponding number of first connecting holes 124. The support plate 111 is provided with a second connecting hole that mates with any of the first connecting holes 124. This allows conventional fasteners to be inserted into the first connecting holes 124 and the second connecting holes to detachably connect the support plate 111 and the first connecting plate 121 together; for example, the fasteners can be bolts 13 and nuts 130 that mate with the bolts 13. Example 2

[0032] This embodiment provides a planar FRP photovoltaic mounting system, such as... Figure 5 As shown, it is similar to that in Embodiment 1, also including at least two sets of support connection units arranged parallel to each other and spaced apart. These support connection units are typically aligned to cooperate with each other. The specific number of support connection units can be adjusted according to the size of the photovoltaic panel b; in this embodiment, there are two sets.

[0033] Each support connection unit includes multiple support seats 11' spaced apart for installation on the base a, and support beams 12' installed on the multiple support seats 11' for installing photovoltaic panels b. The base a can be a generally horizontal location such as the ground or roof; the multiple support seats 11' are usually in the same horizontal plane to install the aforementioned support beams 12' (at this time, the angle formed between the support beams 12' and the base a is an acute angle, so that the photovoltaic panels b are tilted), and the specific number of support seats 11' can be adjusted according to the size of the photovoltaic panels b, which is two in this embodiment. The support beams 12' are made of glass fiber reinforced plastic (i.e., FRP), which has strong design flexibility, is easy to install, has high specific strength, is lightweight, effectively reduces the load-bearing pressure on the main building, and has the advantages of corrosion resistance and good stability; the tensile, compressive, and flexural strength requirements of the glass fiber reinforced plastic are preferably not less than 700MPa, the tensile, compressive, and flexural elastic modulus are all not less than 40GPa, and the performance degradation in the 30-year ultraviolet aging test does not exceed 10% (the same below).

[0034] In this embodiment, the included angle α formed between the supporting beam 12' and the base a is preferably 0 < α ≤ 25°. Each set of supporting connection units also includes a first supporting rod 14' connecting the upper end of the supporting beam 12' and the corresponding support seat 11'. The included angle formed between the first supporting rod 14' and the supporting beam 12' is 10~160°, preferably 50~120°. To increase the connection strength between adjacent sets of supporting connection units, the planar FRP photovoltaic bracket also includes a connecting rod 151' or a connecting rod group 15' connecting two adjacent first supporting rods 14'. The connecting rod 151' or the connecting rod group 15' is horizontally arranged and is usually located in the middle of the first supporting rod 14' (the connecting rod group 15' is usually formed by connecting two or more connecting rods 151'; in this embodiment, a connecting rod group is included, which is formed by two connecting rods 151' staggered and butted together). The first supporting rod 14' and the connecting rod 151' are also preferably made of glass fiber reinforced plastic.

[0035] Similarly, such as Figure 7As shown, the supporting beam 12' includes a first connecting plate 121', a second connecting plate 122', and a third connecting plate 123'. The first connecting plate 121' and the second connecting plate 122' are parallel to each other and spaced apart and aligned. The third connecting plate 123' is formed on the edge of the first connecting plate 121' and the edge of the second connecting plate 122' to connect the first connecting plate 121' and the second connecting plate 122' (these are usually integrally formed, the same below), so that the first connecting plate 121' and the second connecting plate 122' are on the same side of the third connecting plate 123', and the third connecting plate 123' is perpendicular to the first connecting plate 121' or the second connecting plate 122'. The width of the first connecting plate 121' is defined as D, and the width of the second connecting plate 122' is defined as d, then D > d, which can improve the overall strength of the supporting beam 12' and increase the load-bearing capacity of the photovoltaic panel b. In use, the photovoltaic panel b is mounted on the outer surface of the third connecting plate 123' (i.e., the surface facing away from the first connecting plate 121' or the second connecting plate 122'). The aforementioned connecting rod 151' preferably has the same structure as the supporting beam 12'; in this case, care must be taken to avoid mutual interference during connection (e.g., ...). Figure 5 (As shown).

[0036] In this embodiment, the support 11' includes a base plate 112' for mounting on the base a and a support plate 111' formed on and perpendicular to the base plate 112'. The support plate 111' is typically located at the edge of the base plate 112', making the cross-section of the support 11' angular (right-angled). The surface of the support plate 111' facing away from the base plate 112' is defined as its outer surface, and the surface facing the base plate 112' is defined as its inner surface. Similarly, the surface of the first connecting plate 121' facing the second connecting plate 122' is defined as its inner surface, and the surface facing away from the second connecting plate 122' is defined as its outer surface. Thus, when the support plate 111' is connected to the first connecting plate 121' (at which point, the lower end of the first connecting plate 121' is directly connected to the support plate 111'), the inner surface of the support plate 111' contacts the outer surface of the first connecting plate 121'. Furthermore, the two ends of the first support rod 14' are respectively connected to another support base 11' and the first connecting plate 121' (upper end), so that the supporting beam 12' and the other support base 11' are located on the same side of the first support rod 14'; the first support rod 14' can be vertically set or inclined, depending on different scenarios. The first support rod 14' also preferably has the same structure as the supporting beam 12' (i.e., the first support rod 14' includes a fourth connecting plate, a fifth connecting plate, and a sixth connecting plate, the sixth connecting plate being perpendicular to the fourth or fifth connecting plate); at this time, the sixth connecting plate is connected to the first connecting plate 121' so that the outer surface of the sixth connecting plate contacts the outer surface of the first connecting plate 121', and contacts the outer surface of the support plate 111' of the other support base 11'; thereby ensuring the connection strength of the entire planar FRP photovoltaic bracket. The upper part of the support plate 111' has two upwardly extending inclined surfaces 1111', such as Figure 6 As shown, the upper dimension of the support plate 111' gradually decreases in the upward direction, which helps to reduce the use of raw materials and reduce weight. Typically, multiple mounting holes are made in the base plate 112', and the support base 11' is mounted on the base a using connectors 113' installed in these mounting holes; the connectors 113' can be conventional screws, bolts, expansion bolts, or other similar parts.

[0037] At least one first connecting hole 124' is provided at both ends of the first connecting plate 121'. The number of first connecting holes 124' at each end can be determined comprehensively based on factors such as connection strength and space requirements. In this embodiment, two holes are provided at each end. A second connecting hole is provided on the support plate 111' that mates with any of the first connecting holes 124'. This allows conventional fasteners to be inserted into the first connecting holes 124' and the second connecting hole to detachably connect the support plate 111' and the first connecting plate 121' together (e.g., fasteners can be bolts 13' and nuts that mate with bolts 13', the same below). A second connecting hole is provided at the upper end of the first support rod 14', which mates with the first connecting hole 124' at the other end of the first connecting plate 121', and is also connected using conventional fasteners. Thus: the lower end of the first support rod 14' is provided with a third connecting hole, and the first support rod 14' is connected to another support plate 111' (which has a matching connecting hole) using conventional fasteners; the end of the connecting rod 151' is connected to the middle of the first support rod 14', and the opposite ends of the two connecting rods 151' are all connected in the above manner.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
