A column head and photovoltaic support connection structure

Abstract

This utility model relates to the field of photovoltaic bracket technology and discloses a column head and photovoltaic bracket connection structure. The photovoltaic bracket connection structure includes a column, a crossbeam, and a column head. The column head includes a front end plate, a rear end plate, and two side plates. The top height of the front end plate is lower than the top height of the rear end plate, and the top height of the rear end plate is lower than the top height of the two side plates. The bottom of the crossbeam abuts against the tops of the front end plate and the rear end plate. The column head is connected to the column and crossbeam via bolt assemblies. The height difference between the front end plate and the rear end plate allows the crossbeam to naturally form an inclination angle, eliminating the need for additional adjustment, reducing processes, ensuring consistent inclination angles across multiple crossbeams, and shortening assembly time. The bottom of the crossbeam abuts against the front end plate and the rear end plate, distributing the load and preventing deformation or displacement of the crossbeam due to concentrated stress, resulting in higher connection reliability. Both the column and crossbeam are connected to the column head via bolts; disassembly only requires unscrewing the bolts to replace components, eliminating the need for cutting and welding, thus reducing maintenance costs and difficulty.

Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically to a column head for a photovoltaic support and a photovoltaic support connection structure including the column head. Background Technology

[0002] In photovoltaic (PV) support systems, the column head is the core component connecting the uprights and crossbeams, and its structural design directly affects the support stability, assembly flexibility, and service life of the PV support system. Currently, there are two main connection methods between the column head and the uprights / crossbeams in existing PV support systems: hinged connection and welded connection. The hinged connection between the column and the column head will concentrate the force on the hinge axis, resulting in low structural strength and poor stability. Although the welding connection can ensure structural rigidity in the short term, it is inconvenient to disassemble later, and the weld is prone to stress concentration and corrosion, and the assembly efficiency is low. In summary, existing hinged and welded column heads cannot simultaneously achieve support stability, assembly flexibility, and long-term service requirements, necessitating optimized structural design to address these issues. Utility Model Content

[0003] Therefore, it is necessary to provide a connection structure between the column head and the photovoltaic support to address the aforementioned technical problems.

[0004] To achieve the above objectives, this utility model provides a column head, including a front end plate, a rear end plate, and two side plates. The two side plates are arranged in parallel, and the front end plate and the rear end plate are arranged in parallel. The front end plate and the rear end plate are located between the two side plates. The front end plate, the rear end plate, and the two side plates together form a limiting cavity with an open structure at the top and bottom. The top height of the front end plate is lower than the top height of the rear end plate, and the top height of the rear end plate is lower than the top height of the two side plates, so as to adapt to the inclined installation of the crossbeam and form multi-point support.

[0005] Preferably, the tops of the two side plates are at the same height.

[0006] Preferably, the top surfaces of the front end plate, the rear end plate, and the two side plates are all flat. Alternatively, the top surfaces of the front end plate and the rear end plate are parallel inclined planes, and the top surfaces of the two side plates are all flat.

[0007] Preferably, the rear end plate has a notch that divides the rear end plate into two unconnected parts.

[0008] Preferably, the length direction of the notch is the same as the height direction of the rear end plate.

[0009] Preferably, each of the two side plates has at least two upper side mounting holes, and the height of the upper side mounting holes is higher than the top height of the rear end plate.

[0010] Preferably, at least two lower side mounting holes are provided on both side plates, and the height of the lower side mounting holes is lower than the height of the top of the front plate.

[0011] Preferably, the front end plate has at least two front mounting holes, and the rear end plate has a rear mounting hole corresponding to the front mounting holes.

[0012] This utility model also provides a photovoltaic support connection structure, including a column, a crossbeam and the aforementioned column head. The top of the column is located in a limiting cavity. The column head is connected to the column through a lower bolt assembly. The bottom of the crossbeam abuts against the top of the front end plate and the top of the rear end plate. The column head is connected to the crossbeam through an upper bolt assembly.

[0013] The beneficial effects of this technical solution are: 1. The height difference between the front and rear plates allows the crossbeam to naturally form an inclination angle, eliminating the need for additional adjustments, reducing processes, ensuring consistent inclination angles across multiple sets of crossbeams, and shortening assembly time; 2. The bottom of the crossbeam abuts against the front and rear plates to distribute the load and avoid deformation or displacement of the crossbeam caused by concentrated stress, resulting in higher connection reliability; 3. The columns and beams are all connected to the column heads with bolts. When disassembling, you only need to unscrew the bolts to replace the parts. There is no need for cutting and welding, which reduces maintenance costs and difficulty. Attached Figure Description

Detailed Implementation

[0015] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0016] Please see Figures 1 to 8 This application provides a photovoltaic support connection structure, including a column 5, a crossbeam 6, and a column head.

[0017] Please refer to Figures 1 to 4 The column head includes a front plate 1, a rear plate 2, and two side plates 3. The two side plates 3 are arranged in parallel, and the front plate 1 and rear plate 2 are arranged in parallel. The front plate 1 and rear plate 2 are located between the two side plates 3. The front plate 1, rear plate 2, and two side plates 3 together form a limiting cavity 4 with an open structure at the top and bottom. The limiting cavity 4 has a rectangular cross-section. The top height of the front plate 1 is lower than the top height of the rear plate 2, and the top height of the rear plate 2 is lower than the top height of the two side plates 3. This height difference design allows the crossbeam 6 to naturally maintain its tilt after installation, and the tops of the front plate 1 and the rear plate 2 are used to abut against the bottom of the crossbeam 6, forming a two-point support.

[0018] The column head is made of Q235 carbon steel and is integrally formed through sheet metal processing.

[0019] Please see Figure 7 The top of the column 5 is located within the limiting cavity 4. The column 5 has a vertical mounting hole. The column head is connected to the column 5 via a lower bolt assembly 7. The bottom of the crossbeam 6 abuts against the top of the front end plate 1 and the top of the rear end plate 2. The column head is connected to the crossbeam 6 via an upper bolt assembly 8. Both the upper bolt assembly 8 and the lower bolt assembly 7 include bolts and nuts.

[0020] In some embodiments, please refer to Figures 1 to 4 The top heights of the two side plates 3 are set to be the same to ensure structural symmetry and prevent the crossbeam 6 from shifting under stress.

[0021] In some embodiments, please refer to Figures 1 to 4The top surfaces of the front panel 1, rear panel 2, and two side panels 3 are all flat. This facilitates processing and allows the top surfaces of the front panel 1 and rear panel 2 to provide stable support for the crossbeam 6. Alternatively, please refer to... Figure 5 The top surfaces of the front end plate 1 and the rear end plate 2 are set as parallel inclined surfaces, while the top surfaces of the two side plates 3 are flat. The parallel inclined surfaces of the top surfaces of the front end plate 1 and the rear end plate 2 can achieve surface contact with the crossbeam 6, increasing the contact area and further improving the support strength of the crossbeam 6.

[0022] In some embodiments, please refer to Figure 1 The rear end plate 2 is provided with a notch 21, which divides the rear end plate 2 into two unconnected parts. The length direction of the notch 21 is the same as the height direction of the rear end plate 2.

[0023] By setting the notch 21, a deformation space is provided for the column head. When the column head and the crossbeam 6 are connected by the upper bolt assembly 8, the bolt tension can cause the column head to deform slightly, thereby driving the two side plates 3 to move inward and close to each other, thus clamping and fixing the crossbeam 6. At the same time, the column 5 located in the limiting cavity 4 is pressed simultaneously, eliminating the assembly gap and further improving the overall strength of the connection structure.

[0024] For easier connection of the upper bolt assembly 8 to the column head and the beam 6, please refer to [link / reference]. Figure 1 and Figure 2 Each of the two side plates 3 has at least two upper side mounting holes 31, the height of which is higher than the top height of the rear end plate 2. The crossbeam 6 has openings corresponding to the upper side mounting holes 31. Please refer to [reference needed]. Figure 7 The bolts of the upper bolt assembly 8 pass through the upper side mounting holes 31 and the openings of the crossbeam 6 and are then connected to the nuts. After the upper bolt assembly 8 connects the column head and the crossbeam 6, the bolt tension can drive the two side plates 3 to move inward toward each other, thereby clamping and fixing the crossbeam 6, eliminating assembly gaps, and further improving the overall strength of the connection structure.

[0025] Furthermore, to facilitate the connection between the lower bolt assembly 7 and the column head and column 5, please refer to [reference needed]. Figure 1 and Figure 2 The front panel 1 has two front mounting holes 11, and the rear panel 2 has a rear mounting hole 22 corresponding to the front mounting holes 11. The column 5 has corresponding openings; please refer to [reference needed]. Figure 7 The bolts of the lower bolt assembly 7 pass through the front mounting hole 11, the opening in the column 5, and the rear mounting hole 22 before being connected to the nut. After the lower bolt assembly 7 connects the column head and the column 5, the bolt tension can drive the two rear end plates 2 to move inward, thereby clamping and fixing the column 5, eliminating assembly gaps, and further improving the overall strength of the connection structure.

[0026] Alternatively, please see Figure 6 Each of the two side plates 3 has two lower side mounting holes 32, the height of which is lower than the top height of the front plate 1. The column 5 has openings corresponding to the lower side mounting holes 32; please refer to [reference needed]. Figure 8 The bolts of the lower bolt assembly 7 pass through the mounting holes 32 on the lower side and the openings in the column 5, and are then connected to the nuts. After the lower bolt assembly 7 connects the column head and the column 5, the bolt tension can drive the two side plates 3 to move inward toward each other, thereby clamping and fixing the column 5, eliminating assembly gaps, and further improving the overall strength of the connection structure.

[0027] Please see Figure 6 The lower side mounting hole 32 can be opened simultaneously with the front mounting hole 11 and the rear mounting hole 22, which facilitates flexible selection of connection methods. Alternatively, one of them can be opened separately, that is, the lower side mounting hole 32 can be opened alone, or the front mounting hole 11 and the rear mounting hole 22 can be opened alone.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
