Description

Technical Field

[0001] At least one embodiment of the present utility model relates to the field of photovoltaic technology, and in particular to a support mechanism and a photovoltaic bracket. Background Art

[0002] The photovoltaic support based on the ball node grid structure mainly includes a grid structure and a base, wherein the grid structure is suitable for limiting the installation surface for installing photovoltaic components, and the base is suitable for fixing the grid structure equipped with photovoltaic components on an external installation foundation.

[0003] Currently, the base used mainly includes a base plate, ribs vertically mounted on the base plate, and bolt balls connected to the upper part of the ribs. Among them, the bolt balls located in the grid structure serve as part of the ball nodes in the grid structure and are suitable for connecting with some rods in the grid structure.

[0004] In actual use cases, photovoltaic panels often need to be arranged at an angle to meet the lighting requirements of the light field. To achieve this, the grid structure must be connected to the base at an angle relative to the horizontal plane to meet the pitch angle requirements of the photovoltaic panels. Due to the limited structure of the base and grid structure sharing the bolt ball, in some use cases with large pitch angles, the connection between the ribs and the bolt ball often obstructs the connection of the grid structure rods, thereby limiting the angle between the mounting surface defined by the grid structure and the horizontal plane. Utility Model Content

[0005] To address at least one of the aforementioned and other technical issues in the prior art, the present invention provides a support mechanism and photovoltaic support. The base is indirectly mounted to an external mounting foundation via connectors. The mounting angle of the grid structure is determined by the relative angle between the connectors and the mounting foundation, independent of the mounting position of the base relative to the grid structure. Therefore, the grid structure's rods are not obstructed.

[0006] An embodiment of the present invention provides a support mechanism comprising a base, the base comprising a bolt ball adapted to connect to a rod of an external grid structure, and a support portion disposed below the bolt ball, the support portion being configured to support the bolt ball along a normal direction of a mounting surface defined by the grid structure. A connector comprises a main body, a first portion disposed at an upper end of the main body, and a second portion disposed at a lower end of the main body; wherein an angle is formed between a normal to a first end surface of the first portion connected to the support portion and a normal to a second end surface of the second portion connected to an external mounting base.

[0007] In an illustrative embodiment, the first portion and / or the second portion is configured as a flange structure.

[0008] In an illustrative embodiment, the main body is configured as a cylindrical structure.

[0009] In an illustrative embodiment, a stiffening plate is provided at the connection between the first portion and / or the second portion and the main body.

[0010] In an exemplary embodiment, the bolt ball is used as a ball node of the truss structure, and is suitable for connecting the web members and / or chord members of the truss structure.

[0011] In an exemplary embodiment, the supporting portion includes: a bottom plate arranged in a direction parallel to the first end surface of the first portion; and a rib plate arranged between the bottom plate and the bolt ball in a direction perpendicular to the bottom plate.

[0012] In an illustrative embodiment, the supporting mechanism includes a plurality of ribs, which are cross-arranged on the base plate; wherein, in the orthographic projection along a direction perpendicular to the base plate, the intersection position of the plurality of ribs coincides with the projection of the center of the bolt ball.

[0013] In an illustrative embodiment, the support mechanism further includes a transition plate, which is arranged between the base and the connecting member and / or between the connecting member and the mounting base.

[0014] An embodiment of the utility model also provides a photovoltaic bracket, including a truss mechanism and a supporting mechanism, wherein the bolt ball of the base of the supporting mechanism is used as a node for connecting a part of the chord rod of the truss mechanism; wherein the extension direction of the chord rod connected to the bolt ball is perpendicular to the supporting direction of the base of the supporting mechanism.

[0015] According to the support mechanism and photovoltaic support provided by the present invention, the base is indirectly mounted on an external mounting base via a connector, and the grid structure is installed at an angle corresponding to the angle between the connector and the mounting base, so that a suitable angle is formed between the mounting surface defined by the grid structure and the horizontal plane. Because the connector is disposed on the outside of the grid structure, it does not obstruct the rods in the grid structure. Moreover, because the mounting position of the base relative to the grid structure does not affect the angle of the mounting surface, the base can be pre-installed on the grid structure, thereby simplifying on-site installation of the photovoltaic support.

[0039] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0040] The terms used herein are only for describing specific embodiments and are not intended to limit the present invention. The terms "comprise", "include", etc. used herein indicate the presence of the features, steps, operations and / or components, but do not exclude the presence or addition of one or more other features, steps, operations or components.

[0041] All terms used herein, including technical and scientific terms, have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0042] When expressions such as “at least one of A, B, and C, etc.” are used, they should generally be interpreted in accordance with the meaning commonly understood by those skilled in the art. For example, “a system having at least one of A, B, and C” should include but is not limited to systems having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, and C, etc. When expressions such as “at least one of A, B, or C, etc.” are used, they should generally be interpreted in accordance with the meaning commonly understood by those skilled in the art. For example, “a system having at least one of A, B, or C” should include but is not limited to systems having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, and C, etc.

[0043] Photovoltaic modules are mostly installed in the light field through photovoltaic brackets. Commonly used photovoltaic brackets mainly include a grid structure and a base. The grid structure defines the installation surface for installing the photovoltaic modules (such as the upper end surface of the grid structure), and the base is used to erect the grid structure on an external installation foundation so that the photovoltaic modules can be arranged at a certain angle in the light field.

[0044] The bolt balls in the base serve as a spherical node for the grid structure, supporting a portion of the rods. These are then welded to the ribs in the base and mounted to an external mounting base via a base plate. To ensure the mounting surface is aligned with the light in the light field, the grid structure is often arranged at an angle to the horizontal. To achieve this, the bolt balls and ribs must be welded at an appropriate angle. However, if the mounting surface is too far from the horizontal, the connection between the bolt balls and the ribs on the upper portion of the ribs will obstruct the bolt holes provided by the bolt balls, preventing the grid structure from being installed smoothly.

[0045] Therefore, based on the overall inventive concept, how to provide a supporting mechanism and photovoltaic bracket that will not block the poles of the grid structure and can be easily installed on site has become a technical problem that needs to be solved urgently.

[0046] Figure 1It is a three-dimensional diagram of a photovoltaic bracket according to an exemplary embodiment of the present invention. Figure 2 yes Figure 1 A partially enlarged view of the photovoltaic bracket of the exemplary embodiment is shown.

[0047] According to the photovoltaic bracket provided by the utility model, Figure 1 and Figure 2 As shown, the structure includes a grid structure 2 and a support structure 1. The bolt ball 111 of the base 11 of the support structure 1 serves as a ball node for connecting a portion of the chord 22 of the grid structure 2. The chord 22 connected to the bolt ball 111 extends in a direction perpendicular to the support direction of the base 11 of the support structure 1.

[0048] In an illustrative embodiment, Figure 1 As shown, the truss structure 2 includes chord members 22 and web members 21. Specifically, some chord members 22 are connected end-to-end via ball joints and arranged within a first plane. Other chord members 22 are connected end-to-end via ball joints and arranged within a second plane located below and parallel to the first plane. Furthermore, the chord members 22 located within the first and second planes are connected via diagonally braced web members 21.

[0049] In an illustrative embodiment, Figure 1 and Figure 2 As shown, the grid structure 2 also includes crossbeams 23 and purlins (not shown in the figure due to being obscured by the photovoltaic modules 4). Specifically, multiple crossbeams 23 are arranged in parallel and spaced apart above the chords 22 in the first plane. Furthermore, multiple purlins are evenly spaced apart at the upper ends of the crossbeams 23 in a direction perpendicular to the crossbeams 23. The upper ends of the multiple purlins are arranged coplanarly to define a mounting surface for mounting the photovoltaic modules 4.

[0050] In an illustrative embodiment, Figure 1 and Figure 2 As shown, the connecting member 12 mounts the base 11 on an external mounting base 3. The mounting base 3 includes but is not limited to any one of a column, the ground, a table protruding from the ground, and a groove sunken into the ground.

[0051] In an illustrative embodiment, Figure 1 and Figure 2 As shown, the bolt balls 11 of the support structure 1 serve as a portion of the spherical nodes within the second surface of the truss structure 2. Specifically, these bolt balls 11 include, but are not limited to, eight bolt holes. The axes of four of these bolt holes align with the second surface, suitable for mounting opposite chord members 22. The axes of the other four bolt holes extend obliquely to the second surface, allowing for mounting the diagonally braced web members 21.

[0052] Figure 3It is a three-dimensional diagram of a support mechanism according to an illustrative embodiment of the present utility model.

[0053] According to the support mechanism provided by the utility model, Figure 3 As shown, it includes a base 11 and a connector 12. The base 11 includes a bolt ball 111 suitable for connecting to the rods of the external grid structure 2, and a support portion provided at the bottom of the bolt ball 111. The support portion is configured to support the bolt ball 111 along the normal direction of the installation surface defined by the grid structure 2. The connector 12 includes a main body 122, a first portion 121 provided at the upper end of the main body 122, and a second portion 124 provided at the lower end of the main body 122. The normal line of the first end surface of the first portion 121 connected to the support portion and the normal line of the second end surface of the second portion 124 connected to the external mounting base 3 form an angle.

[0054] In such an embodiment, the base 11 is indirectly mounted on the external mounting base 3 via the connector 12. Based on the support mechanism 1, the mounting angle of the grid mechanism 2 relative to the horizontal plane is configured by the relative angle between the connector 12 and the mounting base 3. Since the connector 12 is located on the outside of the grid mechanism 2, it will not conflict with the rods in the grid mechanism 2, and the angle between the mounting surface defined by the grid mechanism 2 and the horizontal plane can have a larger setting range. On this basis, since the mounting position of the base 11 relative to the grid mechanism 2 does not affect the angle of the mounting surface, the base 11 can be pre-installed on the grid mechanism without the need for assembly (such as welding) at the installation site, which also simplifies the on-site installation of the photovoltaic bracket.

[0055] According to the embodiment of the present utility model, Figure 3 As shown, the bolt ball 111 is used as a ball node of the truss structure 2 and is suitable for connecting the web members 21 and / or chord members 22 of the truss structure 2.

[0056] According to the embodiment of the present utility model, Figure 3 As shown, the support mechanism 1 further includes a transition plate 13 , which is arranged between the base 11 and the connecting member 12 and / or between the connecting member 12 and the installation base 3 .

[0057] In another exemplary embodiment, the base 11 is mounted on the connector 12 via a transition plate 13. Specifically, the transition plate 13 is disposed between the bottom plate 113 of the base 11 and the first portion 121 of the connector 12. The transition plate 13 is provided with a first mounting hole for assembly with the bottom plate 113 and a second mounting hole for assembly with the first portion 121, respectively. This allows for compensating for minor misalignment caused by component installation errors and / or manufacturing precision during installation.

[0060] According to the embodiment of the present utility model, Figure 3 and Figure 4 As shown, the support mechanism 1 includes a plurality of ribs 112, which are cross-arranged on a base plate 113. In the orthographic projection along a direction perpendicular to the base plate 113, the intersection position of the plurality of ribs 112 coincides with the projection of the center of the bolt ball 111.

[0061] In an illustrative embodiment, Figure 4 As shown, the bottom plate 113 includes but is not limited to a plate that is constructed into a substantially square shape (e.g., the four corners of the bottom plate 113 are constructed into chamfers). Figure 4 Ribs 112 are arranged in a cross shape on the end surface (shown facing away from the page). The upper portion of the ribs 112 forms grooves that match the external shape of the bolt ball (including but not limited to the shape and radius of the bolt ball) for welding to the surface of the bolt ball 111. The upper ends of the ribs 112 can extend to approximately the middle of the bolt ball to more stably secure the bolt ball 111 to the ribs 112. It should be understood that the embodiments of the present invention are not limited to this.

[0062] For example, the bottom plate 113 may also be configured as a circular, elliptical, polygonal, rectangular or any other shape suitable for assembly with the connector 12 .

[0063] For another example, the ribs 112 are provided in the form of three, four, five, or any other number.

[0066] According to the embodiment of the present utility model, Figure 3 and Figure 5 As shown, the first portion 121 and / or the second portion 124 are configured as flange structures.

[0067] According to the embodiment of the present utility model, Figure 3 and Figure 5 As shown, a stiffening plate 123 is provided at the connection between the first portion 121 and / or the second portion 124 and the main body 122 .

[0068] In an illustrative embodiment, Figure 3 As shown, the main body 122 includes, but is not limited to, a hollow circular tube, preferably designed to minimize weight while maintaining structural strength. Furthermore, the first portion 121 includes, but is not limited to, a substantially square plate, mounted to the upper end of the main body 122 in a radial direction parallel to the main body 122. The first portion 121 may be mounted to the main body 122 by, but is not limited to, riveting, welding, or any other method. It should be understood that the embodiments of the present invention are not limited thereto.

[0070] For another example, the first portion 121 may be a circular, elliptical, polygonal or other plate that adapts to the cross-sectional shape of the main body 122 .

[0071] In an illustrative embodiment, Figure 3 and Figure 5 As shown, the second portion 124 includes but is not limited to an annular plate, and the second portion 124 protrudes outward along the circumference of the main body 122. A first angle is formed between a surface defined by the extension direction of the second portion 124 and a surface defined by the extension line of the first portion 121, and a second angle is formed between the mounting surface defined by the grid structure 2 and a horizontal plane to be substantially the same, thereby enabling the grid structure 2 to be installed at an angle on the mounting foundation.

[0072] In an illustrative embodiment, Figure 4 and Figure 5 As shown, multiple through holes are provided at intervals on the first portion 122 and the second portion 124 to form a flange structure connected to the bottom plate 113 of the base 1 and the mounting base 3.
