Description

Technical Field

[0001] This utility model relates to the photovoltaic field, and in particular to a photovoltaic support column. Background Technology

[0002] In photovoltaic (PV) mounting systems, the columns are essential supporting foundations. As components that support PV modules, the PV mounting systems require high strength from the columns. Because H-beams have an I-shaped cross-section, the web and flanges form a stable force transmission path, and their section modulus is significantly better than that of split beams. Therefore, H-beams are commonly used for PV mounting columns. However, H-beams are standard components. When processed according to the European standard EN 10034, their wall thickness is relatively large, leading to excessive strength and high production costs, resulting in unnecessary waste. Furthermore, existing H-beams have relatively weak load-bearing capacity in the weak axis direction. When the column experiences weak axis stress in certain environments, the existing H-beams may not provide sufficient strength. Utility Model Content

[0003] The purpose of this invention is to provide a photovoltaic support column that can meet the need for cost reduction while increasing the load-bearing capacity in the weak axis direction and improving the support strength.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A photovoltaic support column includes two parts, each part including a web extending in a first direction and two wing plates connected to opposite ends of the web plate and angled to the web plate, the web plates of the two parts being fixedly connected, and at least one wing plate having a bent reinforcing short plate integrally connected to its end away from the web plate, the reinforcing short plate being angled to the wing plate.

[0006] As a further improvement of this utility model, the wing plate is arranged perpendicularly to the web plate; and / or, the reinforcing short plate is arranged perpendicularly to the wing plate.

[0007] As a further improvement of the present invention, the two parts are symmetrically arranged, and the web plate and the two wing plates of each part together form a cavity, and the openings of the cavities of the two parts are arranged opposite to each other.

[0008] As a further improvement of this utility model, each of the components is bent toward or away from the cavity.

[0009] As a further improvement of the present invention, each of the two reinforcing short plates of each of the split parts is bent at the ends of their respective corresponding wing plates toward or away from the cavity.

[0010] As a further improvement of this utility model, each of the components is formed by cold bending.

[0011] As a further improvement of this utility model, the length of each of the reinforcing short plates is 1 / 10 to 1 / 8 of the length of the web plate.

[0012] As a further improvement of this utility model, the length of each of the wing plates is 1 / 4 to 1 / 3 of the length of the web plate.

[0013] As a further improvement of this utility model, the connection between the web plate and the wing plate and / or the connection between the wing plate and the reinforcing short plate is provided with a chamfer formed by bending, and the chamfer is one of a rounded corner and a beveled corner.

[0014] As a further improvement of this utility model, the two web plates are fixedly connected as one unit by bolts, riveting, or welding.

[0015] As a further improvement of the present invention, the two web plates are fixedly connected as one unit by bolts, and the bolts are at least two sets arranged vertically and vertically, with each set including at least two sets arranged horizontally and vertically. The two web plates are fixedly connected as one unit by at least four bolts.

[0016] Compared to existing technologies, this invention forms an H-beam by splicing two separate parts, reducing steel consumption and lowering production costs. Each of the parts includes a web and two wing plates, and each wing plate has a reinforcing short plate at its end. Therefore, the photovoltaic support column of this invention can meet the force requirements in the strong axis direction while also increasing the bearing capacity in the weak axis direction through the reinforcing short plate, thereby improving the support strength of the photovoltaic support column of this invention.

[0030] The exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. If several embodiments exist, features in these embodiments may be combined with each other without conflict. When the description refers to the drawings, unless otherwise stated, the same numbers in different drawings represent the same or similar elements. The descriptions in the following exemplary embodiments do not represent all embodiments consistent with the present invention; rather, they are merely examples of apparatuses, products, and / or methods consistent with some aspects of the present invention as set forth in the claims.

[0031] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the scope of protection of this invention. The singular forms “a,” “the,” or “the” used in the specification and claims of this invention are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0032] It should be understood that the terms "first," "second," and similar words used in the specification and claims of this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish the features. Similarly, the terms "an" or "a" do not indicate a quantity limitation, but rather indicate the presence of at least one. Unless otherwise stated, the terms "front," "back," "left," "right," "upper," "lower," and similar words appearing in this utility model are for ease of explanation only and are not limited to a specific location or spatial orientation. The terms "comprising" or "including" are an open-ended expression, meaning that the element preceding "comprising" or "including" covers the element following "comprising" or "including" and its equivalents, which does not exclude that the element preceding "comprising" or "including" may also include other elements. If "several" appears in this utility model, it means two or more.

[0033] Existing H-beams, such as Figure 1 As shown, existing H-beams include two parallel flanges and a web between the two flanges to connect them. The strong axis refers to the direction with a larger moment of inertia and higher bending stiffness, while the weak axis is the direction with a smaller moment of inertia and lower bending stiffness. In terms of bearing capacity, the axis corresponding to the direction of the web is the strong axis direction, and the direction of flange extension is the weak axis direction.

[0034] Please refer to Figures 2 to 13 As shown, this utility model relates to a photovoltaic support column 200, which includes two parts 100. Each part 100 includes a web plate 1 extending in a first direction and two wing plates 2 connected to opposite ends of the web plate 1 and arranged at an angle to the web plate 1. The term "arranged at an angle" here means that the wing plates 2 are perpendicular or inclined to the web plate 1. The web plates 1 of the two parts 100 are fixedly connected. At least one wing plate 2 has a bent reinforcing short plate 3 integrally connected to its end away from the web plate 1. The reinforcing short plate 3 is arranged at an angle to the wing plate 2. The term "arranged at an angle" here means that the reinforcing short plate 3 is perpendicular to the wing plate 2, or inclined inward or outward relative to the wing plate 2. This invention forms an H-beam by splicing two separate parts 100, which reduces the amount of steel used and helps to lower production costs. The photovoltaic support column 200 of this invention is fixedly connected by the web plates 1 of the two separate parts 100, which can meet the force requirements in the first direction (strong axis direction). The photovoltaic support column 200 of this invention also enhances the bearing capacity of the H-beam in the second direction (weak axis direction) by adding a reinforcing short plate 3.

[0035] Furthermore, the wing plate 2 is perpendicular to the web plate 1; and / or, the reinforcing short plate 3 is perpendicular to the wing plate 2. Please refer to [the relevant documentation / reference]. Figure 4 In a specific embodiment, the wing plate 2 is arranged perpendicularly to the web plate 1, and the reinforcing short plate 3 is also arranged perpendicularly to the wing plate 2. Therefore, the wing plate 2 extends along the second direction, the reinforcing short plate 3 is parallel to the web plate 1, and the wing plate 2 is perpendicularly connected between the reinforcing short plate 3 and the web plate 1. That is, each of the segments 100 extends from each end of the web plate 1 by a 90-degree bend to form the wing plate 2, and the wing plate 2 extends again by a 90-degree bend at its end to form the reinforcing short plate 3.

[0036] Please refer to Figures 2 to 13 As shown, in the specific embodiment, the two segments 100 are identical in structure and size. Each segment 100 has a height direction (LL). Each segment 100 includes a web 1 and two wing plates 2. Therefore, in the photovoltaic support column 200 of this utility model, the number of webs 1 is two and the number of wing plates 2 is four. For each segment 100, the web 1 is... Figure 1 Extending along a first direction (MM), two wing plates 2 are integrally connected to opposite ends of the web plate 1 and extend along a second direction (NN) perpendicular to the first direction. For the two components 100, the first direction can also be called the strong axis direction, and the second direction can also be called the weak axis direction. The first direction (strong axis direction), the second direction (weak axis direction), and the height direction are mutually perpendicular. The two components 100 are symmetrically arranged back-to-back. This symmetrical arrangement means that the photovoltaic support column 200 of this invention is symmetrically arranged in both the first direction (strong axis direction) and the second direction (weak axis direction). The web plate 1 and the two wing plates 2 of each component 100 together form a cavity 4, and the openings of the cavities 4 of the two components 100 are arranged opposite to each other. This opposite opening allows the photovoltaic support column 200 of this invention to be an H-beam in terms of overall structure.

[0037] In a specific embodiment, each of the components 100 is formed by cold bending. Compared with hot-rolled steel, cold-bent steel produced by the cold bending process has different manufacturing processes and production equipment. Hot-rolled steel equipment is expensive, while cold-bent steel equipment is inexpensive, and it can save 30% of materials for the same strength.

[0038] Please refer to Figure 4 , Figure 7 and Figure 10As shown, each of the two sub-sections 100 includes two reinforcing short plates 3, and the two sub-sections 100 together include four reinforcing short plates 3. Each reinforcing short plate 3 is parallel to the web 1, and the four reinforcing short plates 3 have the same length. That is, after adding the reinforcing short plates 3 extending in the first direction, the photovoltaic support column 200 of this utility model is still an axisymmetric figure along the first direction and an axisymmetric figure along the second direction. In other words, although the reinforcing short plates 3 are added, the photovoltaic support column 200 of this utility model is still an H-shaped steel as a whole. Due to the addition of the reinforcing short plates 3, the bearing capacity in the weak axis direction can be strengthened, thereby improving the overall support strength of the photovoltaic support column 200.

[0039] Please refer to Figures 2 to 4 The first embodiment shown and Figures 8 to 10 In the third embodiment shown, each of the two reinforcing short plates 3 of each of the sub-body 100 bends inward toward each other at the ends of their respective corresponding wing plates 2. The inward bending mentioned here refers to the bending relative to the opening between the two wing plates 2 of the same sub-body 100. The arrangement of the two reinforcing short plates 3 on the same sub-body 100 bending in the same inward direction ensures that the overall dimension of the photovoltaic support column 200 of this invention does not increase in the direction of the strong axis.

[0040] Please refer to Figures 5 to 7 In the second embodiment shown, each of the two reinforcing short plates 3 of each of the split parts 100 is bent outwards at the ends of their respective corresponding wing plates 2. Since the outward bending increases the overall size of the photovoltaic bracket column 200 of this utility model in the direction of the strong axis, that is, by using outwardly bent "U"-shaped steel, it does not occupy the opening position between the two wing plates 2, and is more convenient for the fixed installation of the two split parts 100.

[0041] Based on the above embodiments one and two, it can be understood that each of the two reinforcing short plates 3 of each of the split parts 100 bends at the ends of their respective corresponding wing plates 2 in a direction closer to or further away from the cavity 4. This ensures that the photovoltaic support column 200 of this utility model, with its large H-shaped steel frame, has enhanced load-bearing capacity in the weak axis direction while allowing for slight structural deformation to meet different customer needs.

[0042] Please refer to Figure 4 , Figure 7 and Figure 10As shown, the length of each reinforcing spur 3 is 1 / 10 to 1 / 8 of the length of the web 1. This arrangement, where the length of the reinforcing spur 3 is much smaller than the length of the web 1, provides a certain degree of reinforcement, meaning the load-bearing capacity in the weak axis direction is increased, thereby improving the support strength of the photovoltaic support column 200.

[0043] Please refer to Figure 4 , Figure 7 and Figure 10 As shown, the length of each wing plate 2 is 1 / 4 to 1 / 3 of the length of the web plate 1. This length of the wing plate 2 is set in such a way that the first direction in which the web plate 1 is located is the strong axis direction and the second direction in which the wing plate 2 is located is the weak axis direction. In summary, the length of each wing plate 2 is 1 / 4 to 1 / 3 of the length of the web plate 1, and the length of each reinforcing short plate 3 is 1 / 10 to 1 / 8 of the length of the web plate 1. That is, the length of the reinforcing short plate 3 < the length of the wing plate 2 < the length of the web plate 1, which satisfies the structural strength requirements of the photovoltaic support column 200 of this utility model without causing problems for the web plate 1 and the wing plates 2.

[0044] Please refer to Figures 12 to 13 As shown, the connection between the web plate 1 and the wing plate 2 and / or the connection between the wing plate 2 and the reinforcing short plate 3 are chamfered. Figure 12 Specifically, in Embodiments 1 and 2, the connection between the web plate 1 and the wing plate 2 is shown to have a rounded corner 41. Figure 13 Specifically, in Embodiment 3, the connection between the web 1 and the wing plate 2 is shown to be at a chamfered angle of 42. Although an enlarged view is not provided for the chamfer at the connection between the wing plate 2 and the reinforcing short plate 3, in the specific embodiment it is... Figure 12 Similar to the rounded corner 41 shown, other embodiments may also be similar. Figure 13 A similar chamfer 42 is shown. Therefore, the chamfers at the connection between the web 1 and the wing 2 and the connection between the wing 2 and the reinforcing short plate 3 can be either a rounded corner 41 or a chamfer 42.

[0045] Please refer to Figures 2 to 13 As shown in the specific embodiment, the two web plates 1 are fixedly connected as one unit by bolts 5. Besides bolt connection, welding, riveting, and other fixing methods can also be used. Riveting can take various forms such as blind rivets, ring groove rivets, and boom rivets, as long as a fixed connection between the two is achieved. Multiple connection and fixing methods are available for users to choose from, allowing for a comprehensive consideration of cost and stability requirements.

[0046] Please refer to Figures 2 to 13 And specifically refer to Figure 11As shown, in a specific embodiment, the two web plates 1 are fixedly connected as a whole by bolts 5. The bolts 5 are arranged in at least two sets vertically, with each set including at least two bolts arranged horizontally, meaning the two web plates 1 are fixedly connected as a whole by at least four bolts 5. Of course, this invention can also provide two or more sets of bolts 5 according to the overall height of the photovoltaic support column 200. In this specific embodiment, four sets of bolts 5 are provided, totaling eight (vertical, horizontal, and vertical), making the connection more stable.

[0047] In summary, this utility model first forms an H-beam by splicing two separate parts 100, which reduces the amount of steel used and helps to lower production costs. Furthermore, by adding a reinforcing short plate 3, this utility model enables the photovoltaic support column 200 to meet the force requirements in the strong axis direction while also increasing the bearing capacity in the weak axis direction through the reinforcing short plate 3, thereby improving the support strength of the photovoltaic support column 200.
