Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic products, and in particular to an adjustable photovoltaic bracket and photovoltaic module that can be applied to complex terrain. Background Technology

[0002] Traditional photovoltaic (PV) mounting technology is showing its limitations when facing complex terrain. Early mounting systems often employed simple structural designs, such as straight-plate clamps paired with standard connectors, which were only suitable for ideal sites with flat terrain and simple geological conditions. As PV projects expand to wider areas, such as deserts and hilly regions with complex terrain, problems have arisen one after another.

[0003] These terrains are highly undulating and have irregular slopes, making it difficult to accurately control the elevation and slope of each point during construction surveying. This results in frequent positional deviations during the installation of the support structure. Traditional support structures, such as the adjustable single-column photovoltaic support structure for complex terrain disclosed in Chinese Patent CN 105827186 A, can adjust the installation height of the solar panels, but they require foundation piles for fixation. However, for areas with highly undulating terrain and irregular slopes, the deviations that occur during the assembly process of this photovoltaic support structure still lack an effective adjustment mechanism. Subsequent correction work is time-consuming and labor-intensive, greatly hindering the construction progress. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable photovoltaic bracket and photovoltaic module, which is suitable for photovoltaic installation in complex terrain. It has the advantages of stable structure, ensuring long-term stable operation of photovoltaic system, and improving installation efficiency and facilitating construction.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] An adjustable photovoltaic support includes a support frame, a clamp assembly, a crossbeam, a diagonal beam, and a diagonal beam connector;

[0007] The bracket is used to stand on the ground; the clamp assembly is height-adjustable and is attached to the top of the bracket, and the top of the clamp assembly is hinged to the middle of the crossbeam; the two ends of the crossbeam are respectively provided with a number of end hinge holes spaced along the length direction;

[0008] The inclined beam has two parts, which are respectively set on the left and right sides of the clamp assembly. The upper end of the inclined beam is hinged to one of the hinge holes at the end of the crossbeam. The lower end of the inclined beam is connected to the bottom of the clamp assembly through the inclined beam connector.

[0009] One end of the inclined beam connector is hinged to the clamp assembly via a first hinge shaft, and the other end is hinged to the lower end of the inclined beam via a second hinge shaft. The first and second hinge shafts are spaced apart from each other and perpendicularly intersecting.

[0010] Furthermore, the inclined beam connector includes a main body and two connecting ears, which are spaced apart on one side of the main body; the main body has a first hinge hole through which the first hinge shaft passes; the two connecting ears are distributed along a direction perpendicular to the axial direction of the first hinge hole, and each of the two connecting ears has a second hinge hole through which the second hinge shaft passes, and the lower end of the inclined beam can swing back and forth between the two connecting ears.

[0011] Furthermore, it also includes several longitudinal beams, which are spaced apart along the length of the transverse beams. Each longitudinal beam is hinged to the transverse beam via an "L"-shaped longitudinal beam connector; the space between the longitudinal beams is used to install solar panels.

[0012] Furthermore, the upper piece of the longitudinal beam connector is provided with a strip-shaped upper hinge hole, and the upper piece abuts against the side of the longitudinal beam. An upper bolt for locking and fixing with the longitudinal beam passes through the upper hinge hole. The longitudinal beam is provided with several strip-shaped longitudinal beam hinge holes, each for locking with the upper bolt. The lower piece of the longitudinal beam connector is provided with a lower hinge hole, and the lower piece abuts against the top surface of the crossbeam. A lower bolt for locking and fixing with the crossbeam passes through the lower hinge hole.

[0013] Furthermore, the adjustable photovoltaic support is in multiple groups, with each group of adjustable photovoltaic support arranged longitudinally in sequence, and the longitudinally adjacent beams are connected in sequence; multiple solar panels are arranged in an array on the longitudinal beams.

[0014] Furthermore, the inclined beams, cross beams, and longitudinal beams are all C-shaped channel steel.

[0015] Furthermore, the bracket is a rhomboid prism; the clamp assembly includes a rhomboid clamp; the mounting ears of the rhomboid clamp are located on the left and right edges of the bracket.

[0016] Furthermore, the clamp assembly includes at least one diamond-shaped clamp, one limiting member, and two connecting posts; the diamond-shaped clamp is fitted around the top of the support, the limiting member is spaced above the diamond-shaped clamp and rests on the top surface of the support, and the two connecting posts are located on the left and right sides of the support, respectively, and are locked to the mounting ears at the left and right ends of the diamond-shaped clamp and the left and right ends of the limiting member; the upper part of the connecting post has several connecting post locking holes spaced vertically, each connecting post locking hole is selectively locked to the limiting member, and the upper end of the connecting post is hinged to one of the multiple central hinge holes spaced along the length direction provided in the middle of the crossbeam.

[0020] During installation, the top of the photovoltaic bracket is hinged to the middle of the crossbeam via a clamp assembly, while the sides are supported by inclined beams hinged to both ends of the crossbeam. The angle of the crossbeam and its solar panels can be adjusted by using different end hinge holes where the upper end of the inclined beam is hinged to the end of the crossbeam to meet lighting requirements. When the bracket is erected on uneven ground, the lower end of the inclined beam can be rotated left and right via the first hinge shaft of the inclined beam connector, and rotated forward and backward via the second hinge shaft. This allows for easy adjustment of the connection angle between the lower end of the inclined beam and the clamp assembly on the bracket, solving the problem of bracket tilting due to uneven ground and hindering installation. The photovoltaic bracket boasts high assembly efficiency, stable and reliable structural connections, and avoids unstable locking.

[0021] Therefore, the installation efficiency of photovoltaic brackets in complex terrain can be effectively improved by using simple inclined beam connectors. The inclined beam connectors have a simple structure, low manufacturing cost, and are easy to install and maintain, effectively helping photovoltaic systems to be built efficiently and operate stably.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0034] like Figure 1 As shown, a photovoltaic module 100 of this embodiment includes an adjustable photovoltaic bracket 10 and a solar panel 20, with the solar panel 20 mounted on the top of the adjustable photovoltaic bracket 10. Utilizing the adjustable photovoltaic bracket 10, the photovoltaic module 100 of this embodiment is widely applicable to complex areas with large terrain undulations and irregular slopes, such as deserts and hilly areas, exhibiting good applicability and construction efficiency, and ensuring the long-term stable operation of the photovoltaic module 100.

[0035] Specifically, such as Figures 2 to 9 As shown, the adjustable photovoltaic bracket 10 of this embodiment includes a bracket 1, a clamp assembly 2, a crossbeam 3, a diagonal beam 4, and a diagonal beam connector 5.

[0036] The support 1 is used to stand on the ground; the clamp assembly 2 is height-adjustable and is attached to the top of the support 1. The height of the clamp assembly 2 can be adjusted according to the terrain. The top of the clamp assembly 2 is hinged to the middle of the crossbeam 3; the two ends of the crossbeam 3 are respectively provided with a number of end hinge holes 31 arranged at intervals along the length direction.

[0037] Two inclined beams 4 are respectively disposed on the left and right sides of the clamp assembly 2. The upper end of the inclined beam 4 is hinged to one of the end hinge holes 31 of the end of the crossbeam 3. The lower end of the inclined beam 4 is connected to the bottom of the clamp assembly 2 through the inclined beam connector 5. One end of the inclined beam connector 5 is hinged to the clamp assembly 2 through the first hinge shaft 55, and the other end is hinged to the lower end of the inclined beam 4 through the second hinge shaft 56. The first hinge shaft 55 and the second hinge shaft 56 are distributed at intervals and perpendicular to each other.

[0038] Therefore, this embodiment mainly uses the inclined beam connector 5 to realize the up-down and left-right adjustment function of the inclined beam 4, which can flexibly adapt to the undulations and slope changes of complex terrain, and ensure that when the uneven ground causes the photovoltaic bracket 1 to have installation deviation, it can be quickly and accurately corrected, making up for the shortcomings of traditional bracket adjustment.

[0039] Specifically, during installation, the top of the photovoltaic bracket 1 can be hinged to the middle of the crossbeam 3 via the clamp assembly 2, and the two sides of the bracket 1 are hinged to the ends of the crossbeam 3 via the inclined beams 4. The angle of the crossbeam 3 and the solar panels 20 on it can be adjusted according to the different end hinge holes 31 at the ends of the crossbeam 3 where the upper end of the inclined beam 4 is hinged to meet the requirements of light collection. When the bracket 1 is erected on an uneven ground, the lower end of the inclined beam 4 can be rotated left and right by the first hinge shaft 55 of the inclined beam connector 5, and the lower end of the inclined beam 4 can be rotated back and forth by the second hinge shaft 56. This allows for easy adjustment of the connection angle between the lower end of the inclined beam 4 and the clamp assembly 2 on the bracket 1, thus solving the problem of the bracket 1 tilting due to uneven ground and being unable to be installed smoothly. The photovoltaic bracket 1 has high assembly efficiency, stable and reliable structural connection, and will not cause unstable locking.

[0040] This embodiment uses a simple inclined beam connector 5 to effectively improve the installation efficiency of the photovoltaic bracket 1 in complex terrain. The inclined beam connector 5 has a simple structure, low manufacturing cost, and is easy to install and maintain, effectively helping the photovoltaic system to be built efficiently and operate stably.

[0041] like Figure 8 As shown, the specific inclined beam connector 5 includes a main body 51 and two connecting ears 52, which are spaced apart on one side of the main body 51. The main body 51 has a first hinge hole 53 through which a first hinge shaft 55 passes. The two connecting ears 52 are distributed along a direction perpendicular to the axial direction of the first hinge hole 53. Each connecting ear 52 has a second hinge hole 54 through which a second hinge shaft 56 passes, and the lower end of the inclined beam 4 can swing back and forth between the two connecting ears 52. This facilitates the installation of the inclined beam connector 5, the inclined beam 4, and the bracket 1.

[0042] like Figure 1 , Figure 2 and Figure 4The adjustable photovoltaic bracket 10 also includes several longitudinal beams 6. This embodiment uses four longitudinal beams 6 as an example for explanation. Each longitudinal beam 6 is distributed laterally at intervals along the length of the crossbeam 3. Each longitudinal beam 6 and the crossbeam 3 can be hinged together by an "L"-shaped longitudinal beam connector 7. The space between each longitudinal beam 6 is used to install solar panels 20.

[0043] See Figure 3 , Figure 5 and Figure 10 The upper plate 71 of the longitudinal beam connector 7 has a strip-shaped upper hinge hole 711, and the upper plate 71 abuts against the side of the longitudinal beam 6. An upper bolt 712, which is locked and fixed to the longitudinal beam 6, passes through the upper hinge hole 711. The longitudinal beam 6 has several strip-shaped longitudinal beam hinge holes 61, each for locking with the upper bolt 712. The lower plate 72 of the longitudinal beam connector 7 has a lower hinge hole 721, and the lower plate 72 abuts against the top surface of the crossbeam 3. A lower bolt 722, which is locked and fixed to the crossbeam 3, passes through the lower hinge hole 721. Therefore, the lower bolt 722 can be used as an axis to allow the longitudinal beam connector 7 to rotate and shift, thereby easily adjusting the installation position of the longitudinal beam 6 relative to the crossbeam 3, and thus changing the position of the photovoltaic panel to ensure optimal light transmission.

[0044] like Figure 1 As shown, the photovoltaic module 100 may include multiple sets of adjustable photovoltaic brackets 10, each set of adjustable photovoltaic brackets 10 is arranged longitudinally in sequence, and each longitudinally adjacent longitudinal beam 6 is connected in sequence; multiple solar panels 20 are arranged in an array on the longitudinal beam 6.

[0045] In this embodiment, the inclined beam 4, the horizontal beam 3, and the longitudinal beam 6 can all be C-shaped channel steel or other materials, which makes the structure stable and reliable, and convenient for production, manufacturing, and installation.

[0046] For example Figure 6 and Figure 7 As shown, the bracket 1 in this embodiment is a rhomboid prism; the clamp assembly 2 includes a rhomboid clamp 21; the mounting ears 211 of the rhomboid clamp 21 are located at the edges 11 on the left and right sides of the bracket 1.

[0047] This embodiment adopts a diamond-shaped clamp 21 structure, abandoning the traditional clamp style. Unlike traditional clamps, which are mostly rectangular or circular structures, stress concentration is likely to occur when clamping the support 1, affecting the long-term stability of the support 1. The diamond-shaped clamp 21 structure of this embodiment utilizes its geometric characteristics to evenly distribute stress when clamping the support 1, overcoming the problem of stress concentration in traditional clamps and ensuring that the support 1 can withstand external forces stably for a long time.

[0048] Specifically, the clamp assembly 2 may include at least one diamond-shaped clamp 21, a limiting member 22, and two connecting posts 23; in this embodiment, two diamond-shaped clamps 21 with vertical spacing are provided to make its clamping effect better.

[0049] Two diamond-shaped clamps 21 are both attached to the top of the bracket 1. The limiting member 22 is spaced above the two diamond-shaped clamps 21 and rests on the top surface of the bracket 1. Two connecting columns 23 are located on the left and right sides of the bracket 1, and are respectively locked to the mounting ears 211 at the left and right ends of the diamond-shaped clamps 21 and the left and right ends of the limiting member 22. In this embodiment, the outer end of one of the mounting ears 211 of the lower diamond-shaped clamp 21 can also extend to form a connecting part 212. The connecting part 212 can be passed through by the first hinge shaft 55 of the inclined beam connector 5 for hinged connection.

[0050] The mounting bolts 213 that pass through the mounting ears 211 at the left and right ends of the diamond-shaped clamp 21 can be simultaneously passed through the connecting column 23 for fixation, thereby improving installation efficiency.

[0051] The upper part of the connecting column 23 has several connecting column locking holes 231 distributed vertically. Each connecting column locking hole 231 is selectively locked to the limiting member 22. The upper end of the connecting column 23 is hinged to one of the multiple central hinge holes 32 distributed along the length direction in the middle of the crossbeam 3. Thus, by adjusting the connection between the limiting member 22 and the connecting column locking holes 231 of different heights of the connecting column 23, the height position of the clamp assembly 2 relative to the bracket 1 can be adjusted.

[0052] In this embodiment, the end hinge hole 31, the middle hinge hole 32, and the connecting post lock hole 231 are all strip-shaped holes to facilitate installation and fine-tuning.

[0053] In summary, the adjustable photovoltaic bracket 10 proposed in this utility model can significantly improve construction efficiency, avoid the time-consuming and laborious subsequent correction work caused by the position deviation of the bracket 1, and can be quickly installed under different terrains and slopes. At the same time, it optimizes the mechanical properties of the bracket 1, disperses stress through the diamond-shaped clamp 21, ensures the long-term stability of the bracket 1, and reduces safety hazards. As a result, the power generation efficiency of the photovoltaic module 100 can be improved, the solar panel 20 can be adapted to light collection, and the slope of the bracket 1 can be adapted to improve power generation efficiency.
