Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation system support structure technology, and in particular to a photovoltaic bracket installation structure. Background Technology

[0002] Photovoltaic flexible support structures achieve large-span installations through cable-stayed architecture. The side columns, as key load-bearing components, need to simultaneously connect the tension force from the upper module cables and the balancing tension force from the lateral side anchors. In existing technologies, side columns are often made of rectangular tubing, with multiple independent plates (such as perforated plates and ear plates) welded together to connect the module cables and side anchors separately. This separate welding method has significant drawbacks: First, it involves a large amount of welding work, resulting in low production efficiency and high labor costs; second, because the connection points of the module cables and the side anchors are perpendicular in space, the tension of the two sets of cables cannot act on the same axis, thus generating harmful bending moments and shear forces on the side columns, affecting structural safety and stability; furthermore, the perforations of the module cables often have right-angle edges, which are prone to cutting the cable body over long-term use, and different projects require repeated non-standard design and welding, resulting in poor versatility. Utility Model Content

[0003] To address the problems of shear force generated by misalignment of cable forces on the side columns of photovoltaic brackets in existing technologies, as well as the low efficiency and poor versatility caused by cumbersome welding processes, this utility model proposes a photovoltaic bracket installation structure.

[0004] The specific technical solution is as follows:

[0005] A photovoltaic support structure includes: side posts, module cables, and side anchors;

[0006] An anchor connector is fixed to the side of the side post by fasteners, and the anchor connector includes:

[0007] An anchor plate, one side of which is used to support the anchor that anchors the component cable;

[0008] A pair of connecting lugs are provided on the side of the anchor pad, and the connecting lugs are provided with connecting holes for connecting the side anchor by means of a swivel bolt;

[0009] A transverse crescent-shaped boss is positioned between the anchor plate and a pair of connecting lugs. The cable-passing area for the component cable to pass through is located on the anchor plate, and the center of force of the cable-passing area is on the same straight line as the center of force of the side anchor in the connecting hole. By fixing the integrated cable-anchor connector to the side post as an independent component and aligning the centers of force of the component cable and the side anchor on the same straight line, the shear force on the side post is fundamentally eliminated, improving structural safety and stability. Simultaneously, this modular design replaces the traditional multi-part welding method, significantly reducing welding volume and on-site work, achieving efficient installation and universal application.

[0010] Furthermore, the cable anchor connector is a one-piece casting. Using a one-piece casting results in high structural strength and good integrity, enabling the molding of complex structures in a single step. This avoids the accumulated dimensional errors and welding defects of multiple welded parts, further ensuring product quality and production efficiency.

[0011] Furthermore, the cable-passing area is a slotted hole formed in the anchor plate. The slotted hole provides the necessary angle adjustment margin for the component cable, adapting to different installation and tensioning conditions, and enhancing the adaptability and fault tolerance of the structure.

[0012] Furthermore, the edges of the oblong hole are rounded. This rounded edge treatment effectively prevents sharp edges from cutting and damaging the component cable, greatly extending the service life of the component cable and improving system safety.

[0013] Furthermore, the side post is provided with elongated holes corresponding to the fasteners for adjusting the installation position. These elongated holes, in conjunction with the fasteners, allow for fine-tuning of the installation position of the cable anchor connector within a certain range, further enhancing the structure's adaptability to different project requirements and strengthening its versatility.

[0014] Furthermore, the back of the cable anchor connector where it connects to the side post is provided with a vertical crescent-shaped boss for engagement and positioning with the side post. The engagement of the vertical crescent-shaped boss on the back with the side post forms an effective positioning and shear-resistant structure, ensuring that the connector will not shift when subjected to enormous cable forces, thus enhancing the reliability of the connection and the force transmission efficiency.

[0015] Furthermore, cylindrical protrusions are provided on both sides of the connecting holes on the pair of connecting lugs. The cylindrical protrusions on both sides of the connecting holes increase the local strength and rigidity of this part, making it less prone to deformation when the swivel bolt is tightened and under stress, thus ensuring long-term stability.

[0016] Furthermore, the side post is a rectangular tube. Using standard rectangular tubes as side posts ensures that the material is readily available, the cost is controllable, and it is easy to match with the positioning structure on the connector, achieving a good combination of standardization and customization.

[0017] The above technical solution has the following advantages or technical effects:

[0018] 1. This utility model achieves force concentration on the side columns of the photovoltaic support through an integrated cable anchor connector and coaxial force-bearing design, completely eliminating harmful shear forces and significantly improving structural safety and durability.

[0019] 2. This utility model replaces the traditional complex welding process with a modular fastening connection method, which greatly reduces the amount of welding work and improves production efficiency and installation convenience.

[0020] 3. This utility model enhances the adaptability and fault tolerance of the structure through adjustable designs such as waist-shaped holes and elongated waist-shaped holes, enabling the product to meet the needs of different projects, achieving a high degree of universality and standardization, and reducing the cost of non-standard design and manufacturing.

[0021] 4. Through detailed design such as casting, rounded corner treatment, positioning bosses and reinforcing protrusions, this utility model effectively protects the component cables while ensuring structural strength, and ensures the reliability and stability of the connection under long-term use.

Detailed Implementation

[0030] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figure 1 As shown, a photovoltaic support installation structure includes: a side post 1, a module cable 2, and a side anchor 3;

[0032] like Figure 2 , Figure 3 As shown, a cable anchor connector 5 is fixed to the side of the side post 1 by fasteners 4. The cable anchor connector 5 includes an anchor pad 5.1.

[0033] like Figure 4 As shown, the anchor plate 5.1 supports and anchors the component cable 2 on its front side. On the side of the anchor plate 5.1, a pair of connecting lugs 5.2 are integrally formed. Connecting holes are provided on these connecting lugs 5.2 for connecting the side anchor 3 via a slip bolt 3.1. Between the anchor plate 5.1 and the pair of connecting lugs 5.2, a transverse crescent-shaped boss 5.3 is provided. The transverse crescent-shaped boss 5.3 enhances the local stiffness and strength of this area and serves as a key structure for force transmission between the component cable 2 and the side anchor 3.

[0034] Cylindrical protrusions are provided on both sides of the connecting hole to distribute stress when the locking bolt 3.1 is tightened, preventing deformation of the connecting lug 5.2. Figure 5 As shown, in order to facilitate the threading and angle adjustment of component cable 2 and to avoid it being cut, a waist-shaped hole 5.11 is provided on the anchor pad 5.1, and the edge of the waist-shaped hole 5.11 is rounded.

[0035] On the back of the cable anchor connector 5, there is also a vertical crescent-shaped boss 5.4, which is used for engagement and positioning with the side post 1.

[0036] The integrated connector design combines the functions that traditional solutions require multiple welded components into one, fundamentally reducing welding processes and material types, and laying the foundation for modular production and rapid installation. In this preferred embodiment, the cable anchor connector 5 is integrally formed through a casting process, thereby achieving excellent integrity and structural strength.

[0037] like Figure 6 As shown, the side post 1 is preferably made of a rectangular tube. On the side of the side post 1, at least one set of fastener 4 holes for installing fasteners 4 are provided, along with a corresponding elongated hole 1.1. The elongated hole 1.1 allows for fine-tuning of the position of the cable anchor connector 5 in the vertical direction. This design greatly enhances the adaptability of the installation structure to different projects and different tensioning heights, and is one of the key features for achieving product versatility.

[0038] When installing the cable anchor connector 5 to the side post 1, align the vertical crescent-shaped boss 5.4 on the back of the cable anchor connector 5 with the mounting surface of the side post 1. The vertical crescent-shaped boss 5.4 serves as initial positioning and enhances shear resistance. Use bolts or other fasteners 4 to sequentially pass through the mounting holes on the connector and the elongated holes 1.1 on the side post 1, and tighten the nuts to securely fix the cable anchor connector 5 to the side post 1. This mechanical connection method using fasteners 4 completely replaces traditional welding, not only speeding up installation but also avoiding thermal deformation and residual stress caused by welding, while also allowing for convenient replacement of components during maintenance.

[0039] After installation, component cable 2 passes through the oblong hole 5.11 on the cable anchor connector 5 and is fixed to the anchor pad 5.1 by the anchor at its end. The side anchor 3 is hinged to the connecting lug 5.2 via a slip bolt 3.1. The tension of component cable 2 acts on the cable-passing area where the oblong hole 5.11 is located, while the balancing tension of the side anchor 3 acts on the connecting hole, such as... Figure 7 As shown, the center of tension of component cable 2 and the center of tension of the balancing force of side anchor 3 are set on the same straight line. The two forces form a pair of equal and opposite balanced forces acting on the side column 1, thus perfectly canceling out the bending moment and shear force generated on the side column 1, with the shear force theoretically being zero. The side column 1 mainly bears the compressive force, and its stress state is greatly improved, resulting in a qualitative improvement in structural safety and stability. The connection method of the slip bolt 3.1 provides a certain degree of rotational freedom for the overall structure, which can better adapt to the small deformation of the cable. The design of the waist-shaped hole 5.11 allows component cable 2 to self-adjust within a certain angle range, ensuring effective tension transmission, while the rounded corners of its edges effectively prevent stress concentration from causing cutting damage to the cable.

[0040] This utility model, through an integrated cable anchor connector 5, combined with a precise coaxial force-bearing design and a detachable fastening connection method, successfully integrates multiple advantages such as reduced welding, concentrated force, easy adjustment, and improved versatility, providing a high-efficiency, reliable, and economical photovoltaic bracket installation solution.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. 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. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
