Description

[Technical Field]

[0001] This utility model belongs to the field of photovoltaic power generation equipment technology, specifically relating to photovoltaic brackets. [Background Technology]

[0002] like Figure 1 As shown, in existing photovoltaic support systems, multiple struts 22, including horizontal and diagonal struts, are connected between columns 21. These struts are screwed to the columns 21 via hinges 100. When the columns 21 and two or three struts need to act on a single node due to structural calculations, this is difficult to achieve because conventional hinges can only connect one strut at a time. Current methods involve arranging hinges both vertically and horizontally, then connecting them to the struts individually. This approach only barely achieves structural connection but deviates significantly from structural simulation calculations, easily leading to short columns that affect column strength. Furthermore, it requires a high number of components, increasing both material and labor costs. [Utility Model Content]

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a hinged joint structure for columns and struts, as well as a photovoltaic support structure. This structure can be simultaneously hinged to multiple struts in multiple directions, and forces can be applied to the same node, resulting in clear force distribution and preventing the formation of short columns.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] First, a hinged joint structure for a column and a strut is provided, which is fixed to the column of a photovoltaic support and hinged to at least two struts. The hinged joint structure includes:

[0006] An upright plate, which is fixed to a column;

[0007] The side plate is perpendicularly connected to the upright plate. The side plate has a pivot hole near the upright plate and an arc-shaped adjustment groove centered on the pivot hole.

[0008] A rotating shaft is connected to a rotating shaft hole;

[0009] An adjusting component is provided, which corresponds to a support rod. The first end of the adjusting component is connected to a rotating shaft. The adjusting component is fixed to the support rod. Adjusting and fixing holes are provided on the adjusting component and the support rod respectively.

[0010] The positioning bolt passes through the adjustment fixing hole and the arc-shaped adjustment groove to fix the adjusting component and the support rod to the side plate.

[0011] Preferably, the adjusting member is an open channel steel, and the support rod is nested and fixed inside the adjusting member.

[0012] Preferably, the openings of at least two adjusting members face the same direction and their sizes decrease one after the other, so that the first ends of the at least two adjusting members are nested, and the central positioning holes are concentrically arranged and connected to the rotating shaft.

[0013] Preferably, two side plates are arranged side by side with a gap between them, forming a movable groove in the gap space, and the adjusting member is disposed in the movable groove.

[0014] Preferably, the side plate has a semi-circular structure, and the pivot hole is located at the center of the semi-circle.

[0015] Preferably, the arc-shaped adjustment groove is provided in two and is arranged radially spaced along the side plate. The adjustment component and the support rod are respectively provided with two adjustment fixing holes, and the two positioning bolts are respectively engaged with the two adjustment fixing holes and the two arc-shaped adjustment grooves.

[0016] Preferably, the upright plate and the side plate are steel plates and are welded and fixed together as one piece.

[0017] Preferably, the upright plate is provided with facade bolt holes, and the column connecting bolts pass through the facade bolt holes to fix the upright plate to the column.

[0018] In addition, a photovoltaic support structure is provided, including a column and a support rod, characterized in that the column and the support rod are connected by the aforementioned hinged node structure.

[0019] Preferably, the column is made of square steel and the strut is made of U-steel.

[0020] The present invention adopts the above technical solution and has the following beneficial effects:

[0021] 1. A semi-circular hinge component is installed at each hinge node, and one semi-circular hinge component can connect multiple struts simultaneously. Adjustable parts are provided in a one-to-one correspondence with the struts, and the first end of the adjustable part is connected to the rotating shaft. Therefore, all adjustable parts can rotate to align with the corresponding strut position. Additionally, the side plate has an arc-shaped adjustment groove centered on the rotating shaft hole. This allows multiple positioning bolts corresponding to multiple struts in multiple directions to connect to the arc-shaped adjustment groove. Even if the adjustable parts rotate to adjust the angle, the adjusting fixing holes and positioning bolts will still correspond to the arc-shaped adjustment groove, facilitating the fixation of the struts. During the construction of a photovoltaic power station, the semi-circular hinge component is fixed to the column via a vertical plate. The struts are pre-drilled, and then the struts and adjusting components are fixed to the arc-shaped adjusting grooves using positioning bolts. This forms a diagonal brace installation and a stable triangular support. Only one component can be used for diagonal brace connections in multiple directions, achieving true force transmission from each diagonal brace to the same node. The force is clear, and it can achieve the effect of combining three or two small components into one, reducing material costs, improving structural stability, and simplifying installation while reducing labor costs.

[0022] 2. Since the adjusting component is an open channel steel, the support rod is nested and fixed inside the adjusting component. In this way, the adjusting and fixing holes on the adjusting component and the support rod correspond, and positioning bolts are used to fix them through the adjusting and fixing holes on the adjusting component and the support rod, as well as the arc-shaped adjusting groove. Therefore, it is convenient for the adjusting component and the support rod to be nested and fixed as a whole.

[0023] 3. The openings of at least two adjusting parts face the same direction and their sizes decrease one after the other. The first ends of at least two adjusting parts can be nested, and the central positioning holes are concentrically set and connected to the rotating shaft. Thus, at least two adjusting parts can rotate relative to each other. They can be stacked or placed at different angles (directions) and do not interfere with each other in different directions. This allows them to be connected to multiple struts in multiple directions. After being fixed to multiple struts, it can be ensured that each strut transmits force to the same point at the hinge node structure, resulting in clear force distribution and avoiding the formation of short columns.

[0024] 4. The adjusting component rotates within the movable groove formed by the two side plates, with the center of the semicircle as the center point. Therefore, when rotated to the corresponding angle, the adjusting fixing hole can always correspond to the arc-shaped adjusting groove, which is convenient for connection with the positioning bolt.

[0025] 5. Two arc-shaped adjustment grooves, two adjustment fixing holes, and two positioning bolts are provided to ensure that the struts are reliably fixed to the adjustment components and the side plates, thereby improving the structural stability of the hinged joint structure.

[0026] 6. The upright plate and side plate are welded and fixed as a whole. The column connecting bolts pass through the bolt holes on the upright plate to fix the upright plate to the column. Multiple bolt holes on the upright plate and multiple column connecting bolts can be provided. The bolt holes on the upright plate can be elongated holes. This facilitates the fixing of the upright plate and side plate as a whole and the connection with the column.

[0036] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0037] Those skilled in the art will understand that, without conflict, the features in the following embodiments and implementations can be combined with each other.

[0038] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. For example, terms such as "upper," "lower," "lateral," and "longitudinal," which indicate orientation or positional relationship, are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0041] like Figures 2 to 6 As shown, a photovoltaic support 2 includes an inclined beam and columns 21 supporting the inclined beam. In conjunction with existing technology, the inclined beam extends longitudinally, with a horizontal beam vertically intersecting and fixed on it, and photovoltaic modules are installed on the horizontal beam. Additionally, struts 22 are provided between the columns 21 to enhance the structural strength between the columns. When the columns and two or three struts need to act on the same node due to structural calculations, a hinged node structure 1 as shown in this embodiment can be provided. The hinged node structure 1 includes a semi-circular hinge component and positioning bolts 14, wherein the semi-circular hinge component includes:

[0042] Upright plate 11, which is fixed to column 21;

[0043] Side plate 12, which is perpendicularly connected to the upright plate 11, has a pivot hole near the upright plate and an arc-shaped adjustment groove 121 with the pivot hole as the center.

[0044] A rotating shaft is connected to a rotating shaft hole;

[0045] Adjusting component 13 is provided in a one-to-one correspondence with support rod 22. The first end of the adjusting component 13 is connected to the rotating shaft through the central positioning hole. The adjusting component 13 is fixed to the support rod 22. Adjusting and fixing holes are provided on the adjusting component 13 and the support rod 22 respectively.

[0046] The positioning bolt 14 passes through the adjustment fixing hole and the arc-shaped adjustment groove 121 to fix the adjustment component 13 and the support rod 22 to the side plate 12.

[0047] The above technical solution involves setting a semi-circular hinge component at each hinge node, allowing multiple support rods to be connected simultaneously. Each adjustment component corresponds to a support rod, with its first end connected to a pivot shaft. Therefore, all adjustment components can rotate to align with their respective support rod positions. Furthermore, the side plate features an arc-shaped adjustment groove centered on the pivot shaft hole. This allows multiple positioning bolts for multiple support rods in multiple directions to connect to the arc-shaped adjustment groove. Even when the adjustment components rotate to adjust the angle, the adjusting holes and positioning bolts remain aligned with the arc-shaped adjustment groove, facilitating the fixation of the support rods. During the construction of a photovoltaic power station, the semi-circular hinge component is fixed to the column via a vertical plate. The struts are pre-drilled, and then the struts and adjusting components are fixed to the arc-shaped adjusting grooves using positioning bolts. This forms a diagonal bracing installation and a stable triangular support. Only one component can be used for connecting diagonal braces (struts) in multiple directions, achieving true force transmission from each diagonal brace (strut) to the same node. The force is clear, and it can achieve the effect of combining three or two small components into one, reducing material costs, improving structural stability, and simplifying installation while reducing labor costs.

[0048] In some embodiments, the adjusting member 13 is an open channel steel, and the support rod 22 is nested and fixed inside the adjusting member. In this way, the adjusting and fixing holes on the adjusting member 13 and the support rod 22 correspond, and the positioning bolts 14 are used to fix them through the adjusting and fixing holes on the adjusting member and the support rod and the arc-shaped adjusting groove, thus facilitating the nesting and fixing of the adjusting member and the support rod into one piece.

[0049] Since the adjusting member 13 is made of open channel steel, furthermore, the openings of at least two adjusting members 13 face the same direction and their sizes decrease progressively, so that the first ends of at least two adjusting members are nested, and the central positioning holes are concentrically set and connected to the rotating shaft. Here, the rotating shaft can also be a positioning bolt or a positioning pin. The struts work together with the adjusting members, so multiple adjusting members can rotate concentrically through the rotating shaft. They can be stacked or rotated relative to each other in different directions without interfering with each other. After being fixed to multiple struts, it can be ensured that the force of each strut at the hinge node structure is transmitted to a single point, the force is clear, and the formation of short columns can be avoided.

[0050] like Figure 6 As shown, taking the installation of three support rods as an example, three adjusting components need to be installed accordingly: the first adjusting component 131, the second adjusting component 132, and the third adjusting component 133. Each adjusting component has a central positioning hole 1301 near its first end and two adjusting fixing holes 1302 arranged side-by-side near its second end. The three adjusting components decrease in size sequentially and can be stacked as shown in the diagram.

[0051] Specifically, two side plates 12 are spaced apart and form a movable groove within the space between them, and the adjusting member 13 is disposed within the movable groove. The side plate 12 has a semi-circular structure, and the pivot hole is located at the center of the semi-circle. Two arc-shaped adjusting grooves 121 are provided and are radially spaced along the side plate, forming two concentric arcs. The adjusting member and the support rod are respectively provided with two adjusting fixing holes, and two positioning bolts are respectively engaged with the two adjusting fixing holes and the two arc-shaped adjusting grooves. The adjusting member rotates within the movable groove formed by the two side plates, with the center of the semi-circle as its center point. Therefore, rotating to the corresponding angle ensures that the adjusting fixing hole always corresponds to the arc-shaped adjusting groove, facilitating connection with the positioning bolts. The presence of two arc-shaped adjusting grooves, two adjusting fixing holes, and two positioning bolts ensures reliable fixation of the support rod to the adjusting member and the side plate, improving the structural stability of the hinged joint structure.

[0052] In this embodiment, the upright plate 11 and the side plate 12 are steel plates and are welded together as a single unit. The upright plate 11 has facade bolt holes 111, through which column connecting bolts 15 pass to fix the upright plate 11 to the column 21. Multiple facade bolt holes and multiple column connecting bolts can be provided; the facade bolt holes can be elongated. This facilitates the fixing of the upright plate and side plate together and their connection to the column.

[0053] It is understandable that one end of the aforementioned strut is connected to the semi-circular hinge component, while the other end can be connected to the adjacent column using a conventional hinge component.

[0054] Understandably, the columns and struts can be made of the same materials as existing technologies, such as U-steel or C-steel, while the columns can be made of square steel or channel steel.

[0055] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the utility model will be included within the scope of the claims.
