Description

Technical Field

[0001] This utility model relates to the field of column base technology, and in particular to a column base for photovoltaic brackets. Background Technology

[0002] In photovoltaic systems, the support column base, as a crucial component of the photovoltaic support structure, is responsible for securing the column to the ground or platform. However, existing support column base designs have some significant shortcomings. First, the connection between the base and the base plate is typically welded. This method not only increases the difficulty and complexity of on-site construction but may also lead to stress concentration at the welded areas, thus affecting the overall stability of the structure. Second, welding often fails to fully utilize materials, resulting in material waste and reduced material utilization. Utility Model Content

[0003] The purpose of this utility model is to provide a column base with high structural stability, high material utilization, and the ability to effectively save on-site assembly processes.

[0004] To achieve the above objectives, the solution of this utility model is as follows: a column base, including a base plate, the middle part of which is divided into several support pieces, the fixed end of the support piece is integrally formed with the base plate, the free end of the support piece is folded upward and outward from the center of the base plate and has a mounting hole, and these support pieces form a plug-in part for inserting the column.

[0005] Furthermore, the type of support piece includes a main support piece and an auxiliary support piece, wherein the height and width of the main support piece are greater than the height and width of the auxiliary support piece.

[0006] Furthermore, the mounting holes on the main support plate are used to mate with the fastening components and the mounting slots on the column to fix the column to the base.

[0007] Furthermore, the support piece is triangular, with the base of the triangular support piece being a fixed end and the top of the triangular support piece being a free end.

[0008] Furthermore, the support plate is perpendicular to the base plate.

[0009] Furthermore, there is a gap between the sides of adjacent support plates.

[0010] Furthermore, the multiple support plates are axially symmetrically distributed on the base.

[0011] Furthermore, the insertion part is polygonal.

[0012] Furthermore, the insertion part is quadrilateral, pentagonal, hexagonal, or octagonal.

[0013] Furthermore, the base plate is provided with fixing through holes around its perimeter. These fixing through holes are used to engage with fastening components to fix the base to the ground or a designated table surface.

[0014] After adopting the above solution, the beneficial effects of this utility model are as follows:

[0015] The support piece on the base is part of the original base plate. During the processing, the material in the middle of the base plate is cut into petals using an integral sheet metal process. Then, the cut parts are folded upwards and outwards to form the support piece.

[0016] The one-piece molding design greatly simplifies the production process, reducing subsequent processing steps such as welding, grinding, and inspection, thereby lowering production costs. On the assembly floor, rapid assembly can be achieved through pre-set mounting holes, eliminating the need for complex welding procedures, simplifying the on-site assembly process, reducing assembly time and manpower requirements, and improving overall production efficiency.

[0017] By completely avoiding the use of subsequent welding, riveting, or other connection methods, the potential threat to corrosion resistance from the heat-affected zone and welding defects is eliminated.

[0018] The support plate and the base plate are integrated, which enhances the overall strength and stability of the structure. In addition, the folding design not only provides a solid support for the column, but also plays a role in mechanical reinforcement, enabling the base to withstand greater loads and improving the safety and reliability of the photovoltaic bracket.

[0019] Furthermore, since the support plate is formed by deformation of the material in the middle of the base plate, it saves on the use of additional materials, improves the utilization rate of materials, and reduces the generation of waste. Attached Figure Description

[0031] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] This utility model provides a column base, such as Figures 1 to 6 As shown, the base includes a base plate 1, and a plurality of support plates 2 are formed in the middle of the base plate 1. These support plates 2 form a plug-in part 12 for inserting the column 4. The column 4 can be inserted into the plug-in part 12, and then the column 4 is fixed to the base by cooperating with the fastening component 3 through the mounting hole 211 reserved on the support plate 2.

[0033] The fixed end of the support piece 2 is integrally formed with the base plate 1, and the free end of the support piece 2 is folded upwards and outwards from the center of the base plate 1. In other words, the support piece 2 is part of the original base plate 1. During processing, the material in the middle of the base plate 1 is cut into petals, and then the cut parts are folded upwards and outwards to form the support piece 2. This design completely avoids the use of subsequent welding, riveting, or other connection methods, ensuring the integrity and consistency of the structure. The integral molding design not only simplifies the production process and reduces subsequent processing steps, thereby reducing the cost and time of on-site assembly, but also significantly improves the overall strength and stability of the structure by reducing connection points. In addition, the folding design not only provides stable support for the column 4, but also plays a role in enhancing the structural strength mechanically, making the entire base more robust and durable.

[0034] This invention uses metal sheet as the raw material to manufacture the base structure with the support piece 2 using integral sheet metal construction. Firstly, it achieves a weld-free structure, meaning that the welding step is eliminated during production, thus accelerating processing speed and shortening the production cycle. Secondly, the integral sheet metal design significantly improves material utilization, as this design utilizes raw materials more effectively than traditional cutting and welding processes, reducing waste and saving material costs. Furthermore, the integral sheet metal base features high structural strength and good stability, meeting the mechanical requirements of various application scenarios. Compared to traditional bases made from iron-based materials through complex processes such as sheet metal work, stamping, and welding, this invention's base maintains high strength and stability while greatly simplifying the production process, reducing production costs, and improving production efficiency.

[0035] To save costs, the support plates 2 can be divided into main support plates 21 and auxiliary support plates 22, which are distributed alternately. The main support plates 21 play a primary supporting and fixing role, such as... Figures 1 to 5 As shown, the height and width of the main support plate 21 are greater than those of the auxiliary support plate 22. In particular, the top of the main support plate 21 protrudes outward on both sides of the mounting hole 211, forming a larger mounting area to improve assembly stability. The main support plate 21 corresponds to the side of the column 4 with the mounting groove 41, and the mounting hole 211 on the main support plate 21 corresponds to the mounting groove 41 on the column 4. The column 4 and the base are fixedly connected by fastening the fastening assembly 3. The fastening assembly 3 can be a T-bolt and nut assembly, but is not limited to it. In contrast, the auxiliary support plate 22 corresponds to the side of the column 4 without the mounting groove 41. With the main support plate 21 already providing sufficient stability for fixing the column 4, the auxiliary support plates 22 mainly serve as supplementary support. They are distributed around the column 4, providing additional support force, but do not need to cooperate with the fastening assembly 3 to directly participate in fixing the column 4. This design not only achieves effective cost control but also ensures the stability and reliability of the entire structure.

[0036] Regarding the shape of support piece 2, it includes, but is not limited to, polygons such as triangles and quadrilaterals. When support piece 2 is triangular, refer to... Figure 3 The bottom of the triangular support plate 2 is the fixed end, and the top of the triangular support plate 2 is the free end. The mounting hole 211 is located at the top of the triangular support plate 2, which facilitates subsequent installation with the fastening component 3.

[0037] refer to Figure 3After being folded up, the support plate 2 remains perpendicular to the base plate 1. The vertical position of the support plate 2 ensures a larger contact area with the outer edge of the column 4, providing more stable and stronger support. Furthermore, after the support plate 2 is folded up, there are gaps between the sides of adjacent support plates 2. These gaps ensure that each support plate 2 remains stable yet flexible in the upright state, facilitating airflow or adjustment of the support structure as needed. At the same time, these cleverly designed gaps reduce friction between materials, extending the service life of the support plate 2.

[0038] These support plates 2 are axially symmetrically distributed on the base, and each support plate 2 can generate a uniform and stable supporting force on the outer periphery of the column 4. This symmetrical distribution not only improves the balance and stability of the overall structure, but also effectively disperses the pressure borne by the column 4, further enhancing the reliability and durability of the support system.

[0039] Regarding the number of support pieces 2, including but not limited to four, five, six, and eight, refer to... Figure 5 and Figure 6 These support pieces 2 of varying numbers form insertion parts 12 in shapes such as quadrilaterals, pentagons, hexagons, and octagons. In practical applications, the appropriate number of support pieces 2 can be selected according to the specific shape and size requirements of the column 4 to ensure that the column 4 can be stably and properly inserted into the insertion part 12, thereby achieving the best support effect.

[0040] Take octagonal column 4 as an example:

[0041] like Figures 1 to 5 As shown, the base has four main support plates 21 and four auxiliary support plates 22, which together form an octagonal insertion part 12 to perfectly fit the octagonal column 4. The lower end of the column 4 is inserted into the octagonal insertion part 12, and the four main support plates 21 are locked to the four main sides of the column 4 by fastening components 3, while the four auxiliary support plates 22 support the other four sides of the column 4.

[0042] In addition, the base plate 1 is provided with fixing through holes 11 around its perimeter, for reference. Figure 1 and Figure 4 The fixing through hole 11 is used to mate with the fastening component 3 (such as an expansion plug, bolt, etc.) to fix the base to the ground or a designated platform. This ensures the stability and reliability of the base under different installation environments, providing a solid foundation for the column 4 and the entire photovoltaic support system.

[0043] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components. Furthermore, the front, back, left, and right directions involved in this embodiment are only as a reference and do not represent the actual orientation in practical application.

[0044] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
