Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a column top connection structure for photovoltaic support columns. Background Technology

[0002] In photovoltaic power generation systems, photovoltaic brackets are the key structures supporting photovoltaic modules, and their stability and reliability directly affect the power generation efficiency and service life of the photovoltaic power generation system.

[0003] As the main supporting component of a photovoltaic (PV) system, the connection structure between the top of the PV support column and other profiles is crucial. Currently, existing connection methods for the top of PV support columns have several shortcomings. Some connection structures are quite simple, relying solely on bolts and other fasteners for direct connection. Over long-term use, this method is prone to loosening and deformation due to external environmental factors such as wind and snow loads, leading to reduced stability at the connection points and ultimately affecting the structural safety of the entire PV system. Utility Model Content

[0004] The purpose of this utility model is to provide a column top connection structure for photovoltaic support columns, which has high structural stability and is easy to assemble.

[0005] To achieve the above objectives, the solution of this utility model is as follows: a column top connection structure for photovoltaic support columns, including a base and a U-shaped clamp. The base has a downward-opening receiving groove for inserting the top of the column profile, and the top of the base is used to support other profiles. The U-shaped clamp opens downward and hugs the profile located on the top of the base, and is fixed to the top of the base by fasteners to fix the profile on the top of the base.

[0006] Furthermore, the base has a plurality of clamping parts that extend vertically downward around the accommodating groove, and these clamping parts are spaced apart and evenly distributed on the base.

[0007] Furthermore, the clamping part is provided with mounting holes.

[0008] Furthermore, the mounting hole is circular, elliptical, or rectangular.

[0009] Furthermore, the shape of the receiving groove is consistent with the shape of the top of the column, and the size of the receiving groove is adapted to the top of the column profile.

[0010] Furthermore, the two ends of the U-shaped clamp extend horizontally outward to form a fixing part, and the bottom surface of the fixing part fits against the top of the base.

[0011] Furthermore, a first fixing hole is provided on the top of the base, and a second fixing hole is provided on the fixing part of the U-shaped clamp at a position corresponding to the first fixing hole. The first fixing hole and the second fixing hole cooperate with the fastener to realize the fixed connection between the U-shaped clamp and the base.

[0012] Furthermore, several triangular reinforcing plates of different sizes are added between the fixing part of the U-shaped clamp and its main body.

[0013] Furthermore, the outer periphery of the U-shaped clamp is provided with reinforcing ribs, which extend along the width direction of the U-shaped clamp body.

[0014] Furthermore, the base and the U-shaped clamp are made of polymer material.

[0015] After adopting the above solution, the beneficial effects of this utility model are as follows:

[0016] High structural stability: This connection structure mainly consists of a base and a U-shaped clamp. The downward-opening receiving groove on the base engages with the insertion point on the top of the column profile, achieving initial stable positioning of the column and base in the vertical direction, effectively preventing vertical swaying of the column. The downward-opening U-shaped clamp hugs the top profile of the base and is fixed to the top of the base, forming a closed and stable connection system, making the connection between the column and the top profile even more secure.

[0017] Easy assembly: During installation, simply insert the top of the column profile into the receiving groove of the base, then attach the U-shaped clamp to the top of the profile of the base, and fix the U-shaped clamp to the top of the base with fasteners to complete the installation. No complicated operation steps or a large number of auxiliary tools are required. Attached Figure Description

[0027] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] This utility model provides a column top connection structure for photovoltaic support columns. The structure features an ingenious overall design, aiming to solve problems such as poor stability and complex assembly in existing four-column top connection methods for photovoltaic support columns. Figures 1 to 5 As shown, the column top connection structure includes a base 1 and a U-shaped clamp 2. The base 1 has a downward-opening receiving groove 11 for inserting the top of the column 4 profile. The top of the base 1 is used to support other profiles such as the inclined beam 5 and the crossbeam. The U-shaped clamp 2, with its opening facing downward, hugs the profile located on top of the base 1 and is fixed to the top of the base 1. Through the synergistic effect of the base 1 and the U-shaped clamp 2, this column top connection structure can effectively and firmly connect the column 4 to the profile on its top, providing a strong guarantee for the safe and stable operation of the photovoltaic support.

[0029] <Base 1>

[0030] In this embodiment, the top of the base 1 is designed as a flat bearing surface, which can be used to support other profiles such as the inclined beam 5 and the crossbeam. Of course, the top of the base 1 can also be provided with a groove-like structure to limit the position of the profiles mounted on it.

[0031] The shape of the receiving groove 11 of the base 1 is basically the same as the shape of the top of the column 4, and its size is adapted to the top of the column 4 profile, so that the top of the column 4 profile can be accurately inserted into it to achieve preliminary positioning and connection. The receiving groove 11 of the base 1 extends vertically downwards around its perimeter to form several clamping parts 12 similar to side plate structures. In this embodiment, the main body of the base 1 first contracts inwards to form a transition area, and then expands outwards, with its outer periphery adopting an arc-shaped transition design. This design not only increases the structural strength of the clamping parts 12, but also makes the contact between the clamping parts 12 and the column 4 smoother.

[0032] The number of clamping portions 12 depends on the shape of the column 4. These clamping portions 12 are spaced and evenly distributed on the base 1, ensuring that after the column 4 is inserted into the receiving groove 11, the clamping portions 12 are evenly distributed on the outer periphery of the column 4 to ensure that the outer periphery of the column 4 can be evenly stressed. Such a layout enables the column 4 to receive uniform support and restraint from all directions when subjected to an external force, thus effectively avoiding problems such as loosening or damage of the connection caused by uneven stress, and greatly improving the stability and reliability of the entire column top connection structure.

[0033] Mounting holes 13 are provided on the clamping portions 12, and these mounting holes 13 correspond to the preset mounting positions (groove positions or through-hole positions) on the outer periphery of the column 4. In actual installation operations, the operator uses the fasteners 3 to cooperate with the mounting holes 13 on the base 1 and the mounting positions on the column 4 to achieve the fixed connection between the base 1 and the column 4. The shape design of the mounting holes 13 has a certain degree of flexibility and can be reasonably selected according to factors such as actual usage requirements, installation conditions, and the specifications and models of the fasteners 3. Common shapes of the mounting holes 13 include circular, rectangular, etc. The shape of the mounting holes 13 can be circular, rectangular, etc. In this embodiment, in order to cooperate with the T-shaped bolt, the mounting holes 13 are designed as rectangles.

[0034] When the column 4 is quadrilateral, a base 1 with a quadrilateral receiving groove 11 is selected; when the column 4 is octagonal, a base 1 with an octagonal receiving groove 11 is correspondingly selected. The number of clamping portions 12 is four, corresponding to the four sides of the column 4 with grooves, refer to Figure 1 , Figure 2 and Figure 5 .

[0035] <U-shaped hoop 2>

[0036] The U-shaped hoop 2 is fixedly connected to the base 1 through the fasteners 3. Its specific structure and installation method are as follows, refer to Figures 1 to 4 :

[0037] A number of first fixing holes 14 are provided at the top of the base 1. The two ends of the U-shaped hoop 2 respectively extend horizontally outward to form fixing portions 21, and the bottom surface of the fixing portions 21 is in contact with the top of the base 1. On the fixing portions 21 of the U-shaped hoop 2, second fixing holes 22 are provided corresponding to the positions of the first fixing holes 14. When the U-shaped hoop 2 is placed on the base 1 and the bottom surface of the fixing portions 21 is in contact with the top of the base 1, the first fixing holes 14 and the second fixing holes 22 correspond one by one. At this time, by locking the fasteners 3 corresponding to the fixing holes, the U-shaped hoop 2 can be fixedly connected to the base 1.

[0038] As a further improvement of the structure, reinforcing ribs 23 are provided on the outer periphery of the U-shaped hoop 2. For example, as Figure 1 and Figure 3As shown, the reinforcing ribs 23 extend along the width direction of the main body of the U-shaped clamp 2 to enhance the overall structural strength and rigidity of the U-shaped clamp 2. By setting these reinforcing ribs 23, the U-shaped clamp 2 can more effectively disperse stress when subjected to external forces, reduce the risk of deformation or damage caused by excessive local stress, and thus improve the stability and reliability of the U-shaped clamp 2 in the connection process, ensuring that it can play a long-term and stable fixing role.

[0039] like Figure 1 and Figure 3 As shown, a triangular reinforcing plate 24 can be added between the fixing part 21 and the main body of the U-shaped clamp 2 to improve the overall structural strength and stability of the U-shaped clamp 2. Specifically, the reinforcing plates 24 located on the front and rear sides of the U-shaped clamp 2 are relatively small, with a height of about 1 / 4 or even less than the height of the U-shaped clamp 2, ensuring sufficient reinforcement while avoiding unnecessary material waste and structural redundancy; while the reinforcing plate 24 located between the front and rear sides of the U-shaped clamp 2 is larger, with a height equal to the height of the U-shaped clamp 2. This design not only effectively enhances the bending and torsional resistance of the U-shaped clamp 2 under external forces, but also improves the overall structural rigidity and durability, ensuring that the U-shaped clamp 2 maintains stable performance and reliable connection during long-term use.

[0040] The base 1 and U-shaped clamp described in this application can be made of polymer materials, such as polyethylene, polypropylene, or polyvinyl chloride. Polymer materials have high plasticity and good processing performance; various complex shapes can be formed through simple injection molding and extrusion processes. Compared with existing solutions, the processing time is greatly shortened, and the procedures are simplified, which helps reduce labor costs. Furthermore, polymer materials have low density and are lighter than iron-based materials, making the product more convenient to transport and install. Polymer materials have good resistance to chemicals such as acids and alkalis, and their corrosion resistance is stronger than that of iron-based materials, enabling them to maintain long-term stable performance in harsh environments. At the same time, the production cost of polymer materials is low, making them suitable for large-scale production.
