Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support equipment technology, and in particular to a photovoltaic wind-resistant structure. Background Technology

[0002] Photovoltaic support structures are used to install photovoltaic panels, and the rigidity of their structure is crucial to the wind resistance of the overall photovoltaic framework.

[0003] Currently, the installation methods for photovoltaic (PV) mounting systems include pre-setting pile foundations and then installing steel structures on the pile foundations to fix the PV panels. This method often uses a main beam spanning across the top of a row of pile foundations, with secondary beams welded or detachably fixed to the main beam. The PV panels are then placed on the secondary beams. This fixing method mainly relies on the main beam for support, while steel supports are set between the main beam and the pile foundations. This method has sufficient rigidity in the direction of the row of pile foundations, but the surface direction of the PV panels is parallel to the main beam. Therefore, the wind direction of the PV panels is perpendicular to the length direction of the main beam, and the wind resistance stiffness along the direction perpendicular to the extension of the main beam mainly relies on the supports, which is insufficient in strength.

[0007] The connecting beam is rigidly installed between two adjacent first beams, with both ends connected to the lower ends of the two adjacent connecting beams respectively.

[0008] Furthermore, the reinforcing components include multiple sets, which are spaced apart along the length of the main beam.

[0009] Furthermore, a support column is provided on the top of the pile foundation, and the lower end of the first beam is inclined away from the first beam. The reinforcing component also includes a second beam, the two ends of which are connected to the first beam and the support column, respectively.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] Example 1

[0026] Please refer to Figures 1-3 The technical solution of this utility model is as follows: a photovoltaic wind-resistant structure, comprising multiple sets of supports spaced apart along a first direction, each support comprising multiple pile foundations 1 spaced apart along a second direction and a main beam 11 disposed on top of the multiple pile foundations 1, the first direction being perpendicular to the second direction, and further comprising a reinforcing component 2 disposed between the multiple sets of supports, the reinforcing component 2 comprising: a first beam 21, rigidly disposed, comprising multiple beams disposed on the multiple sets of supports, the upper end of which is connected to the main beam 11; and a connecting beam 23, rigidly disposed, disposed between two adjacent first beams 21, both ends of which are respectively connected to the lower ends of two adjacent connecting beams 23. Specifically, refer to... Figures 1-3 It should be noted that the pile foundation 1 is a concrete component, the main beam 11 is a steel section set on the top of the pile foundation 1, and the secondary beam 12 is a rigid structural component such as aluminum alloy or stainless steel set on the main beam 11. It is fixed to the main beam 11 by locking components to form a photovoltaic support. In actual application, the photovoltaic supports are set in rows. This application also provides a reinforcing component 2, which includes a first beam 21. The upper end of the first beam 21 is provided with a first connecting plate 210. The upper end of the first beam 21 is detachably and fixedly connected to the main beam 11 by the first connecting plate 210 and connecting components such as locking screws and U-shaped clamps. After the first beam 21 is set on multiple photovoltaic supports, a connecting beam 23 is set at the lower end of the adjacent first beam 21. The connecting beam 23 connects the two adjacent rows of main beams 11, thereby improving the overall strength of the photovoltaic structure and improving the wind resistance performance. The connecting beam 23 is made of steel section.

[0027] Furthermore, as a preferred embodiment, refer to Figure 1 , Figure 2The reinforcing component 2 comprises multiple sets, which are spaced apart along the length of the main beam 11. Specifically, by spaced apart multiple reinforcing components 2 along the second direction, the overall structural strength of the photovoltaic support can be further improved, thereby further enhancing its wind resistance.

[0028] Example 2

[0029] Furthermore, as a specific implementation method, in some embodiments, according to actual construction needs, a support column 10 is installed on top of the pile foundation 1. In the prior art, the support column 10 is mostly made of structural steel, and its lower end is fixed by a bolt pre-embedded in the pile foundation 1. A fourth connecting plate 101 is installed at the upper end of the support column 10, so that the main beam 11 can be locked by locking bolts or U-shaped clamps. When dealing with the pile foundation 1 with the support column 10, refer to... Figures 3-8 This application provides a photovoltaic wind-resistant structure. The top of the pile foundation 1 is provided with a support column 10. The lower end of the first beam 21 is inclined away from the first beam 21. The reinforcing component 2 also includes a second beam 22. The two ends of the second beam 22 are respectively connected to the first beam 21 and the support column 10. The first beam 21, the second beam 22 and the support column 10 are arranged in a triangle.

[0030] Specifically, by tilting the lower end of the first beam 21, and then connecting the first beam 21 and the support column 10 via the second beam 22, refer to... Figure 4 The support column 10, the first beam 21 and the second beam 22 form a stable triangular structure, which can further improve the overall strength of the photovoltaic structure and further improve its wind resistance.

[0031] In one specific embodiment, the two ends of the second beam 22 are connected to the lower ends of the first beam 21 and the support column 10, respectively. Further, as another specific embodiment, refer to... Figure 3 , Figure 4 The support column 10 is provided with a sliding sleeve 24, and the second beam 22 is connected to the sliding sleeve 24.

[0032] Specifically, the sliding sleeve 24 is a rigid sleeve with a nut 240 welded to its side. A through hole corresponding to the nut 240 is drilled on the side wall. The sliding sleeve 24 is positioned after being pressed against the support column 10 by a screw threaded connection to the nut 240. The position of the sliding sleeve 24 can be adjusted according to the length of the second beam 22 and the installation requirements.

[0033] Furthermore, as a preferred embodiment, refer to Figures 5-8The lower end of the first beam 21 has a first pin 212, and the sliding sleeve 24 is provided with a second pin 221 arranged parallel to the first pin 212. The two ends of the second beam 22 are rotatably connected to the first pin 212 and the second pin 221. Specifically, the lower end of the first beam 21 is welded with two first ear plates 211, and the first pin 212 is rotatably mounted on the two first ear plates 211. The upper end of the second beam 22 is welded with two second ear plates 222, which are located on both sides of the two first ear plates 211 and are rotatably connected to the first pin 212. The lower end of the second beam 22 is integrally provided with two third ear plates 220, and the side wall of the sliding sleeve 24 is welded and fixed with a fourth ear plate 241, which is located between the two third ear plates 220. The fourth ear plate 241 is rotatably mounted with a second pin 221, which is rotatably connected to the third ear plates 220. This connection method facilitates assembly.

[0034] Furthermore, as a preferred embodiment, both ends of the connecting beam 23 are detachably and fixedly connected to the first beam 21. (See reference) Figure 4 , Figure 5 , Figure 7 The two ends of the connecting beam 23 are welded with second connecting plates 230. The second connecting plates 230 are set perpendicular to the connecting beam 23. The lower end of the first beam 21 is provided with two third connecting plates 252 on both sides of the first pin 212. The third connecting plates 252 and the second connecting plates 230 are respectively provided with through holes, so that the screw can be passed through the through holes on the second connecting plates 230 and the third connecting plates 252 and then locked to achieve the purpose of disassembly. This arrangement facilitates the assembly of the reinforcement component 2.

[0035] Furthermore, as a specific implementation method, in order to further improve the ease of assembly of the reinforcing component 2, refer to... Figure 7 , Figure 8 A connecting member 25 is rotatably sleeved on the first pin 212, located on both sides of the first pin 212. Two third connecting plates 252 are provided on the connecting member 25, and second connecting plates 230 are provided at both ends of the connecting beam 23. Specifically, the connecting member 25 includes a sleeve 251, with two connecting plates integrally mounted on the sleeve 251 and located on opposite sides of the sleeve 251. (Refer to...) Figure 7In actual use, the sleeve 251 is fitted on the first pin 212 and located between the two first ear plates 211. At this time, the third connecting plate 252 can swing around the axis of the first pin 212. When assembling the connecting beam 23, since the connecting beam 23 is relatively long, it is often hoisted by using a rope to fix the middle. At this time, the connecting beam 23 will swing in the vertical direction, thus affecting the assembly of the connecting beam 23 and the second connecting plate 230. However, the swingable setting of the connecting piece 25 can swing the connecting piece 25 slightly according to the angle of the connecting beam 23, which is more conducive to connecting with the connecting beam 23 and more conducive to assembly. Moreover, the two first ear plates 211 can axially limit the connecting piece 25.

[0036] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
