Description

[Technical field]

[0001] The utility model belongs to the technical field of photovoltaics, and in particular relates to a photovoltaic bracket. [Background technology]

[0002] like Figure 8 As shown, taking a common photovoltaic support structure as an example, it includes a plurality of inclined beams 12 arranged side by side in the horizontal direction, a plurality of cross beams 13 arranged side by side in the longitudinal direction above the plurality of inclined beams, and a column 11 supported under the inclined beams, wherein the bottom of the column is supported on the mounting surface, and the column and the inclined beams as well as the inclined beams and the cross beams are connected by connecting parts.

[0003] However, the current connectors of photovoltaic brackets can only solve the connection in the plane (north-south direction), resulting in the only solution to increase the east-west spacing of photovoltaic brackets is to increase the purlin specifications and the number of purlins. This connection method has two defects:

[0004] 1. After increasing the specifications of the purlins and the number of purlins, the bracket cost will increase significantly, which is not conducive to opening up solutions with wider adaptability and larger spans.

[0005] 2. After increasing the specifications of purlins and the number of purlins, the number of connected nodes will increase accordingly, which will increase the construction difficulty and affect the construction progress. [Contents of the utility model]

[0006] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a photovoltaic bracket with increased lateral length, so as to solve the problem of increasing the lateral length of the photovoltaic panel while avoiding excessive increase in the bracket cost.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A photovoltaic support with increased lateral length comprises a plurality of inclined beams arranged side by side in the transverse direction, a plurality of horizontal beams arranged side by side in the longitudinal direction above the plurality of inclined beams, and columns supported below the inclined beams, wherein at least one end of the horizontal beam is provided with a transverse cantilever section, and the transverse cantilever section extends from the transverse outermost inclined beam to the transverse outer side to increase the lateral length of the photovoltaic support, the cantilever end of the transverse cantilever section is supported on a cantilever support beam below, and an inclined support rod is provided between the cantilever support beam and the column.

[0009] Preferably, a first connecting member and a fastening assembly for fixing the first connecting member to the cantilever support beam and the diagonal support rod are provided between the cantilever support beam and the diagonal support rod.

[0010] Preferably, the upper portion of the first connecting member is provided with a longitudinal slot connected to the cantilever support beam.

[0011] Preferably, a transverse slot connected to the oblique support rod is provided at the lower portion of the first connecting member.

[0012] Preferably, the fastening assembly includes a first bolt fixing the longitudinal slot to the cantilever support beam, and a second bolt fixing the transverse slot to the oblique support rod.

[0013] Preferably, the longitudinal slot is U-shaped steel, and the transverse slot is formed by welding two rectangular steel plates to the bottom surface of the longitudinal slot.

[0014] Preferably, a second connecting member is provided between the oblique support rod and the column.

[0015] Preferably, the second connecting member is a U-shaped steel, the lower end of the oblique support rod is inserted into the inner side of the second connecting member and fixed with a third bolt, and the bottom of the second connecting member is connected to the column with a fourth bolt.

[0016] Preferably, the cross beam, inclined beam, cantilever support beam and inclined support rod are all made of C-shaped steel or U-shaped steel.

[0017] Preferably, the length of the cantilever support beam is equal to the length of the inclined beam.

[0018] The utility model adopts the above technical solution and has the following beneficial effects:

[0019] 1. In the prior art, the end of the beam will extend laterally outward beyond the outermost inclined beam to a certain length, but the length is limited because additional support is required if it is too long. The utility model provides a transverse cantilever section at at least one end of the beam, and the transverse cantilever section extends laterally outward from the outermost inclined beam to a sufficient length to increase the transverse length of the photovoltaic bracket. The length of the transverse cantilever section is usually greater than the width of a single photovoltaic panel, so that at least one row of photovoltaic panels can be added in the transverse direction.

[0020] Since the length of the transverse cantilever section is relatively long, in order to stably support the transverse cantilever section, the lower side of the cantilever end of the transverse cantilever section is supported on a cantilever support beam, and an inclined support rod is provided between the cantilever support beam and the column, thereby forming a stable triangular support structure. In addition, there is no need to increase the columns, and the bracket cost is reduced by reducing the number of columns.

[0021] 2. It is only necessary to increase the length of the cross beam. After installing the photovoltaic bracket in the conventional manner, a cantilever support beam and an oblique support rod are set between the horizontal cantilever section and the column. Then, the cantilever support beam and the oblique support rod can be quickly installed through the first connecting piece and the fastening assembly. Therefore, although the entire photovoltaic bracket has added cantilever support beams and oblique support rods, due to the convenience of construction, the purpose of increasing the horizontal length of the photovoltaic panel can be achieved at a lower cost.

[0022] 3. The longitudinal slot of the first connecting member is fixed to the cantilever support beam by a first bolt fixed to the cantilever support beam, and the longitudinal slot is fixed to the cantilever support beam by a second bolt. In this way, the first connecting member can be quickly plugged into the cantilever support beam and the oblique support rod, and then connected by bolts, which can achieve rapid installation and facilitate the replacement of parts.

[0023] 4. The longitudinal slot is a U-shaped steel, and the transverse slot is formed by welding two rectangular steel plates to the bottom surface of the longitudinal slot. The U-shaped steel used in the longitudinal slot and the two rectangular steel plates constituting the transverse slot can be made of scraps, and the two are welded into an integrated structure, thereby reducing costs by effectively utilizing scraps.

[0024] 5. The second connecting piece is U-shaped steel. The lower end of the oblique support rod is inserted into the inner side of the second connecting piece and fixed with the third bolt. The bottom of the second connecting piece is connected to the column with the fourth bolt. The main connection is bolted, which can achieve quick installation and convenient replacement of parts.

[0025] 6. Since the cross beams, inclined beams, cantilever support beams and inclined support rods are all made of C-shaped steel or U-shaped steel, the unified specifications further reduce the cost, and C-shaped steel or U-shaped steel is a conventional steel material, which is conducive to reducing costs.

[0026] 7. Since the length of the cantilever support beam is equal to the length of the inclined beam, the unified specifications not only reduce costs, but also facilitate unified use during on-site construction.

[0027] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.

[Specific implementation method]

[0038] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0039] Those skilled in the art will appreciate that, in the absence of conflict, the features in the following embodiments and implementations may be combined with each other.

[0040] The terms used in the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. For example, the words "upper", "lower", "lateral", etc., which indicate orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device / element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0041] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0042] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0043] like Figure 8 As shown, a conventional photovoltaic bracket in the prior art includes a plurality of inclined beams 12 arranged side by side in the transverse direction, a plurality of cross beams 13 arranged side by side in the longitudinal direction above the inclined beams, and a column 11 supported below the inclined beams, wherein the outer ends of the cross beams are slightly longer than the outer sides of the inclined beams.

[0044] Reference Figures 1 to 7 As shown, compared with the conventional photovoltaic bracket in the prior art, in order to increase the lateral length of the photovoltaic panel, this embodiment designs a photovoltaic bracket 1 with increased lateral length, wherein at least one end of the crossbeam is provided with a lateral cantilever section 131, and preferably both ends of the crossbeam are provided with a lateral cantilever section 131, and the lateral cantilever section 131 extends from the lateral outermost inclined beam to the lateral outer side to increase the lateral length of the photovoltaic bracket. A cantilever support assembly 2 is provided between the lateral cantilever section 131 and the column 11, and the cantilever support assembly 2 includes a cantilever support beam 21 and an inclined support rod 23. The cantilever end of the lateral cantilever section is supported on the cantilever support beam 21, and an inclined support rod 23 is provided between the cantilever support beam 21 and the column.

[0045] In the prior art, the end of the beam will extend laterally outward beyond the outermost diagonal beam to a certain length, but the length is limited because additional support is required if it is too long. The utility model provides a transverse cantilever section at at least one end of the beam, and the transverse cantilever section extends laterally outward from the outermost diagonal beam to a sufficient length to increase the transverse length of the photovoltaic bracket. For example, the length of the transverse cantilever section is generally greater than the width of a single photovoltaic panel, so that at least one row of photovoltaic panels can be added in the transverse direction.

[0046] Since the length of the transverse cantilever section is relatively long, in order to stably support the transverse cantilever section, the lower side of the cantilever end of the transverse cantilever section is supported on a cantilever support beam, and an inclined support rod is provided between the cantilever support beam and the column, thereby forming a stable triangular support structure. In addition, there is no need to increase the columns, and the bracket cost is reduced by reducing the number of columns.

[0047] In this embodiment, a first connector 22 and a fastening assembly for fixing the first connector 22 to the cantilever support beam 21 and the diagonal support rod 23 are provided between the cantilever support beam 21 and the diagonal support rod 23. It is only necessary to increase the length of the crossbeam, and after installing the photovoltaic bracket in a conventional manner, a cantilever support beam and a diagonal support rod are arranged between the lateral cantilever section and the column, and then the cantilever support beam and the diagonal support rod can be quickly installed through the first connector and the fastening assembly. Therefore, although the whole photovoltaic bracket is increased with cantilever support beams and diagonal support rods, due to the convenience of construction, the purpose of increasing the lateral length of the photovoltaic panel can be achieved at a relatively low cost.

[0048] Specifically, the upper part of the first connecting member 22 is provided with a longitudinal slot 221 connected to the cantilever support beam. The lower part of the first connecting member 22 is provided with a transverse slot 222 connected to the oblique support rod. The fastening assembly includes a first bolt 25 for fixing the longitudinal slot 221 to the cantilever support beam 21, and a second bolt 26 for fixing the transverse slot 222 to the oblique support rod 23. In this way, the first connecting member can be quickly plugged into the cantilever support beam and the oblique support rod, and then connected by bolts, which can achieve rapid installation and facilitate the replacement of components.

[0049] In this embodiment, the longitudinal slot 221 is a U-shaped steel, and the transverse slot 222 is formed by welding two rectangular steel plates to the bottom surface of the longitudinal slot. The U-shaped steel used in the longitudinal slot and the two rectangular steel plates constituting the transverse slot can both be made of scraps, and the two are welded into an integrated structure, thereby reducing costs by effectively utilizing scraps.

[0050] like Figure 3 As shown, a second connecting member 24 is provided between the oblique support rod 23 and the column 11. Specifically, the second connecting member 24 is a U-shaped steel, the lower end of the oblique support rod 23 is inserted into the inner side of the second connecting member 24 and fixed with a third bolt, and the bottom of the second connecting member 24 is connected to the column with a fourth bolt. Bolt connection is mainly adopted, which can achieve quick installation and facilitate replacement of parts.

[0051] Preferably, the cross beam, the inclined beam, the cantilever support beam and the inclined support rod are all made of C-shaped steel or U-shaped steel. The unified specifications further reduce the cost, and C-shaped steel or U-shaped steel is a conventional steel material, which is conducive to reducing the cost. Similarly, the length of the cantilever support beam is equal to the length of the inclined beam. The unified specifications not only reduce the cost, but also facilitate unified use during on-site construction.

[0052] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
