Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support structure technology, specifically to a vertical installation structure for a photovoltaic support. Background Technology

[0002] With the increasing demand for vertically arranged photovoltaic modules in scenarios such as distributed photovoltaics, agricultural photovoltaic integration, landscape fencing, and slope protection, rapid on-site deployment, relocation and reuse, minimal disturbance to the foundation, and facade stability under gusts and pulsating winds have become common engineering requirements in this field. Vertical photovoltaic supports not only bear their own weight and out-of-plane wind pressure / suction, but also face the requirements of uplift and overturning resistance caused by uneven wind exposure of the array; at the same time, projects are often located at sites with significant soil differences, undulating terrain, and limited construction windows, requiring the installation system to have modular assembly, rapid on-site alignment and vertical adjustment capabilities, and convenient maintenance and low-cost relocation throughout its life cycle.

[0003] Existing vertical photovoltaic (PV) supports mostly rely on concrete foundations or integral welded frames with direct-insertion / driven-in ground anchors for installation. These solutions have long construction cycles, involve a lot of wet work, and put a lot of pressure on surface disturbance and spoil disposal. Rigid nodes with integral welding or a few bolts are prone to unclear stress paths and local stress concentrations at the intersection of beams and columns, which can easily lead to loosening of connections and verticality deviation under long-term wind vibration. To obtain lateral and out-of-plane stiffness, thickened components or temporary supports are often used, but there is a lack of standardized connection interfaces and geometrically invariant support configurations. On-site installation and subsequent expansion are limited, and it is still difficult to obtain stable anti-overturning and anti-slip performance in high-wind areas. At the same time, the direct-insertion method with single or few anchors has insufficient pull-out reserve, poor adaptability to soft soil or backfill soil, high disassembly and reuse costs, and low relocation efficiency, making it difficult to meet the comprehensive requirements of rapid deployment and green construction.

[0004] Therefore, there is an urgent need for a modular support system that is designed for vertical photovoltaic applications, uses reversible ground anchors to replace wet foundations, and forms a clear stress surface and reinforces the structure at the nodes. Utility Model Content

[0005] This utility model provides a vertical installation structure for photovoltaic brackets. Through standardized connection interfaces, it enables rapid assembly, vertical alignment, and on-demand expansion, reducing operation and maintenance and relocation costs, shortening the construction cycle, and minimizing disturbance to the foundation and environment. This satisfies the requirements of vertical photovoltaic arrays for stable support, rapid installation, and reusability.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] A vertical installation structure for a photovoltaic bracket includes a crossbeam and a column. The crossbeam and the column are fixed at an intersection. A mesh support is provided at the intersection area of ​​the crossbeam and the column. The extension of the column is provided with a vertical installation structure. The vertical installation structure includes at least one column extension frame and a spiral insertion column. The upper part of the column extension frame is sleeved along the outer side of the column and fixed with bolts. The bottom is provided with a receiving surface for connecting the column extension and the spiral insertion column.

[0008] In a specific embodiment, the column extension frame includes a U-shaped sleeve and a receiving surface. The receiving surface is horizontally arranged, and the U-shaped sleeve and the receiving surface are perpendicular to each other. Bolt holes are provided on both sides of the U-shaped sleeve, which are fixed to the column extension by bolts. The surface of the receiving surface is provided with mounting holes for connecting with the spiral insertion column bolts.

[0009] In a specific embodiment, the spiral insertion post includes a supporting surface, an insertion part, and spiral patterns. The supporting surface and the bearing surface are fixed by bolts, and the bottom insertion part is provided with spiral patterns.

[0010] In one specific embodiment, the connection surface between the U-shaped sleeve and the receiving surface is further provided with reinforcing ribs.

[0011] In a specific embodiment, the vertical installation structure further includes an auxiliary support, with a square tube support extending to both sides with the bearing surface as the bottom edge, and a diagonal bracing connected by a right-angle connecting plate; one end of the diagonal bracing is connected to the right-angle connecting plate, and the other end is connected to the column extension, and the diagonal bracing and the square tube support together form a triangular support.

[0012] In one specific embodiment, the square tube support is provided with a right-angle connecting plate, and a spiral insertion column is also connected to the bottom of the right-angle connecting plate.

[0013] In one specific embodiment, the square tube support, column extension and diagonal bracing in the vertical installation structure are connected by right-angle connecting plates and fixed by bolts, and the whole structure is detachable.

[0014] The beneficial effects of this utility model are as follows:

[0015] The photovoltaic support vertical installation structure of this invention, through the coordinated design of components such as the column extension, column extension frame, spiral insertion column, and U-shaped sleeve pipe, enables the photovoltaic support to achieve rapid on-site anchoring without a concrete foundation, significantly shortening the construction cycle and reducing disturbance to the foundation. The spiral insertion column, screwed into the ground, forms reliable pull-out and overturning resistance, improving overall stability under wind loads. It is also detachable and reusable, facilitating future relocation or maintenance. The U-shaped sleeve pipe is perpendicular to the bearing surface and fixed with bolts, ensuring a clear force transmission path between the column and the ground anchor, high positioning accuracy, and preventing column torsion and eccentric stress, thus improving installation accuracy and structural safety. The bearing surface features standard holes for bolt connection, facilitating rapid on-site assembly, disassembly, and verticality adjustment, adapting to different geological and topographical conditions, and reducing the difficulty of later maintenance.

[0016] By adding reinforcing ribs between the U-shaped sleeve and the bearing surface, the rigidity and load-bearing capacity of the bearing area are improved, preventing loosening of the joint under long-term stress and ensuring the durability and reliability of the connection. The auxiliary support uses square tube supports and inclined supports to form a stable triangular support structure, and is reliably connected to the column extension through right-angle connecting plates, significantly improving lateral and out-of-plane stiffness, enabling the photovoltaic modules to maintain verticality and flatness even under gusts or pulsating winds. The ends of the square tube supports are equipped with spiral insertion columns, forming a multi-point anchoring system, further improving the overall anti-slip and anti-overturning capabilities, and reducing the risk of single-anchor stress and uneven settlement.

[0017] Furthermore, this invention employs a modular structure with all components assembled with bolts, allowing for individual disassembly and replacement of all components. This facilitates transportation, storage, and on-site installation. During later maintenance or array expansion, partial replacement or addition of members can be performed without overall disassembly, reducing operation and maintenance costs. This structure eliminates the need for wet work, reducing construction dust and noise, and is environmentally friendly. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] Example 1

[0032] like Figure 1-3 As shown in the figure, this embodiment provides a vertical installation structure for a photovoltaic bracket, including a crossbeam and a column 1. The crossbeam and the column 1 are fixed together by bolts. A mesh support 2 is provided in the intersection area of ​​the crossbeam and the column 1 to support the node and disperse the concentrated stress transmitted from the crossbeam, so that the crossbeam is subjected to more uniform force, avoids local buckling at the node, and improves the fatigue resistance and long-term stability of the node.

[0033] A column extension frame 3 is provided at the lower end of the column 1. The column extension frame 3 is composed of a U-shaped sleeve 31 and a receiving surface 32. The U-shaped sleeve 31 is sleeved from the outside of the column 1, so that the column 1 is wrapped on three sides. It is fixed to the extension of the column 1 by bolts through the bolt holes on both sides, ensuring that the axis of the column 1 is consistent with the sleeve center of the U-shaped sleeve 31, realizing automatic centering and self-calibration during installation. The receiving surface 32 is arranged horizontally and connected vertically to the U-shaped sleeve 31, so that the vertical pressure from the column 1 can be evenly transmitted to the ground anchor below through the receiving surface 32, avoiding torsional deformation of the column caused by eccentric bending moment. The surface of the receiving surface 32 has multiple standard installation holes. The support surface 41 of the spiral insertion column 4 is connected to the receiving surface 32 by bolts, realizing reliable surface-to-surface pressure transmission.

[0034] The spiral insertion column 4 includes an insertion part 42 and a spiral thread 43. After the insertion part 42 is screwed into the foundation, the spiral thread 43 provides reliable pull-out and overturning resistance, ensuring the stability of the entire photovoltaic support under complex conditions such as gusts and pulsating winds. This structure can be anchored to the ground through screw-in installation, eliminating the need for a concrete foundation. This allows for fast construction, minimal disturbance to the foundation, and suitability for various geological environments and narrow construction sites. Due to the bolted connection, the entire column extension frame 3 and spiral insertion column 4 can be disassembled for easy relocation and reuse, reducing maintenance costs. Furthermore, during installation, fine-tuning can be performed by adjusting the spiral insertion depth and adding shims at the bearing surface 32, achieving precise verticality control of the column 1.

[0035] Example 2

[0036] like Figure 4-8 As shown, based on Embodiment 1, this embodiment further includes an auxiliary support 5. Square tube supports 51 are symmetrically arranged on both sides with the base surface 32 as the base. The ends of the square tube supports 51 are bolted to the base surface 32 via right-angle connecting plates 52, forming a stable multi-directional force-bearing node. The other side of the right-angle connecting plate 52 is bolted to the upper end of a diagonal brace 53, and the lower end of the diagonal brace 53 is bolted to the extension of the column 1, so that the square tube supports 51, the base surface 32, and the diagonal brace 53 together form a geometrically invariant triangular support structure. This triangular support structure significantly improves the lateral stiffness and out-of-plane bending resistance of the support system, enabling the photovoltaic modules to maintain verticality and flatness under strong winds and periodic wind loads, and reducing node relaxation caused by wind-induced vibration.

[0037] To further enhance overall stability, the end of the square tube support 51 is also provided with a threaded hole and connected to a second spiral insertion column 54, so that the bearing surface 32 and the square tube support 51 form a double anchoring point structure, which disperses the force on the ground anchor, reduces the force concentration on a single spiral insertion column, and improves the safety factor against slippage and overturning. Through the double anchoring system, even under foundation conditions such as soft soil or backfill soil, the overall stability of the column 1 and the beam can be maintained, reducing the risk of support tilting caused by uneven settlement.

[0038] Furthermore, the multi-directional hole design of the right-angle connecting plate 52 enables rapid assembly and on-site adjustment of the square tube support 51 and the inclined support 53. Construction personnel can flexibly add or remove support rods according to the actual wind zone level and photovoltaic array scale, achieving expansion as needed. Because the structure uses all-bolted connections, it not only eliminates welding and avoids heat-affected zone corrosion, but also allows for individual replacement of damaged components during later maintenance without requiring overall shutdown and disassembly, reducing operation and maintenance costs and downtime. The entire structure is completely disassembled and recyclable, facilitating transportation and storage, and meeting the requirements of green construction and recycling.

[0039] Example 3

[0040] This embodiment is a supplementary description of the vertical platform of the upper part of the vertical mounting bracket. The vertical platform includes a crossbeam and a column. The crossbeam and the column are fixed at an intersection. The cross section of the column is C-shaped. The column includes a front side plate, a rear side plate and a bottom side plate. The bottom side plate of the C-shaped groove of the column is provided with openings at intervals. One side of the opening extends outward to form a support.

[0041] The crossbeam 1 includes a vertical edge, an upper side edge, a lower side edge, an upper rolled edge, and a lower rolled edge. The upper side edge and the lower side edge are connected to the vertical edge. The upper side edge is folded outward and upward to form the upper rolled edge, and the lower side edge is folded outward and downward to form the lower rolled edge.

[0042] The solar panel guide rail passes through the crossbeam, then through the opening, and is detachably connected to the bracket.

[0043] Specifically, the bracket is provided with a first through hole, and the bracket is fixedly connected to the solar module guide rail through the first through hole.

[0044] More specifically, the two ends of the solar module guide rail are respectively provided with second through holes at their relative positions to fix the bracket and the solar module guide rail; the bracket is fixedly connected to the solar module guide rail through the first through hole and the second through hole.

[0045] Specifically, the bracket and the solar module guide rail are fixedly connected by bolts, which pass through the first through hole and the second through hole and are fixed by nuts.

[0046] A further preferred embodiment of this utility model is that the bracket and the solar module guide rail are fixedly connected by bolts, with the bolts passing through the first through hole and the second through hole and being fixed by nuts.

[0047] The vertical frame also includes a locking block 6, which engages with the crossbeam. The upper side of the locking block 6 engages with the upper rolled edge, and the lower side of the locking block 6 engages with the lower rolled edge. In this embodiment, the locking block 6 uses a solar panel clamping block fixing method, employing a track-back riveting nut 61 for locking. This eliminates the need for back-side installation and allows for direct front-side locking.
