Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a photovoltaic component bearing device and a photovoltaic tracking bracket. Background Art

[0002] Currently, tracking photovoltaic mounts are primarily categorized as rigid and flexible. Rigid tracking mounts use purlins mounted on the main shaft to support and secure the opposite sides of the photovoltaic module. This prevents the purlins from shaking or deforming under load, ensuring uniform force distribution across the photovoltaic module. However, these tracking mounts provide no support for the back of the module, resulting in a low safe load capacity. While lengthening the purlins can improve the module's load-bearing capacity, there are still cases where they cannot meet load requirements.

[0003] The flexible tracking bracket installs the photovoltaic module on the steel cable. The steel cable can provide support for the back of the photovoltaic module, which is beneficial for the photovoltaic module to bear the front load. However, when the photovoltaic module is under load, the steel cable is prone to shaking and deforming, causing the photovoltaic module to bear torsion and pulling force, which can easily lead to damage to the photovoltaic module. In addition, multiple photovoltaic modules are fixed on the same steel cable. If the steel cable fails, multiple photovoltaic modules will be damaged, and the maintenance cost is high.

[0004] Therefore, it is urgent to propose a photovoltaic module carrying device and a photovoltaic tracking bracket to solve the above technical problems. Utility Model Content

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0033] In the description of this utility model, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0035] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are used to refer to positions or locations based on the positions or locations shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0036] This embodiment provides a photovoltaic module supporting device, which improves the load-bearing capacity of the photovoltaic module and reduces the risk of damage to the photovoltaic module through a rigid-flexible combination. It also has a simple structure and low construction cost.

[0037] Specifically, if Figure 1-Figure 5 As shown, the photovoltaic module support device includes a main beam 100, fixed beams 200, and flexible support cables 300. Multiple fixed beams 200 are provided, spaced parallel to each other along the length of the main beam 100. A photovoltaic module 10 is mounted between each pair of adjacent fixed beams 200, with the opposite sides of the photovoltaic module 10 connected to the corresponding fixed beams 200. This means that the fixed beams 200 provide rigid support for the photovoltaic module 10, ensuring uniform force distribution. Flexible support cables 300 are provided between at least some of the fixed beams 200. These cables are used to support the photovoltaic module 10 from the back, improving the photovoltaic module 10's ability to withstand frontal loads.

[0038] The photovoltaic module support device provided in this embodiment achieves a rigid-flexible combination through the fixed beam 200 and the flexible support cable 300. Compared to simply increasing the load-bearing capacity of the photovoltaic module 10 by extending the fixed beam 200, it has a stronger load-lifting capability and can be selected according to the different load requirements of different areas in the same power station, with high flexibility. Compared to flexible tracking brackets, the photovoltaic module 10 is subjected to more uniform force. Even if the flexible support cable 300 accidentally breaks, it will only slightly affect the photovoltaic module 10 at the break and will not affect other photovoltaic modules 10. The assembly cost and maintenance cost are both low. In addition, the flexible support cable 300 provides less obstruction to the photovoltaic module 10, and the impact on the power generation efficiency of the photovoltaic module 10 is small and negligible.

[0039] Alternatively, the flexible support line 300 may be a steel cable.

[0040] Further, see Figure 1 and Figure 2 , the fixing beam 200 is connected to the long side of the photovoltaic module 10. In this way, the distance between the two fixing beams 200 is small, the supporting effect of the photovoltaic module 10 is better, and the risk of deformation of the photovoltaic module 10 is reduced.

[0041] Optionally, multiple flexible support cables 300 may be provided between two adjacent fixed beams 200, and multiple flexible support cables 300 may be provided on both sides of the main beam 100. This arrangement can not only improve the support effect on the back of the photovoltaic module 10, but also improve the force uniformity of the photovoltaic module 10, thereby improving the load-bearing capacity of the photovoltaic module 10, making the photovoltaic module 10 more capable of resisting wind loads, and helping to extend the service life of the photovoltaic module 10.

[0042] For example, the number of flexible support cables 300 between two adjacent fixed beams 200 may be two, three, four, etc., and may be set according to actual needs, and this application does not make any specific limitation.

[0043] In this embodiment, two flexible support cables 300 are provided between two adjacent fixed beams 200 , and the two flexible support cables 300 are symmetrically arranged on both sides of the main beam 100 .

[0044] Optionally, in one possible embodiment, flexible support cables 300 are provided between the fixed beams 200 at the two ends of the main beam 100. Because the photovoltaic modules 10 located on the periphery are subject to greater wind loads, while the photovoltaic modules 10 located on the interior are subject to less wind loads, based on wind load calculation results, the flexible support cables 300 can be arranged only between the fixed beams 200 at the two ends of the main beam 100. This arrangement can both ensure the wind load resistance of the photovoltaic modules 10 and reduce component costs.

[0045] It is worth noting that in the entire power station, multiple photovoltaic component carrying devices will be used to lay the photovoltaic components 10. For example, multiple photovoltaic component carrying devices are arranged in an array. At this time, flexible support cables 300 can be installed in the high-load area outside the arranged photovoltaic component group, while flexible support cables 300 are not set in the inner low-load area.

[0046] Optionally, in another possible embodiment, a flexible support cable 300 may be provided between every two adjacent fixing beams 200 . Such a configuration can better improve the load-bearing capacity of the photovoltaic assembly 10 .

[0047] Furthermore, in one possible embodiment, multiple fixed beams 200 may share a single flexible support cable 300. This configuration facilitates assembly of the flexible support cable 300. In another possible embodiment, a single flexible support cable 300 is used between two adjacent fixed beams 200. This configuration improves assembly flexibility of the flexible support cable 300 and facilitates collaborative work by multiple workers, thereby improving assembly efficiency.

[0048] Further, see Figure 3 and Figure 5 The fixed beam 200 is provided with a connection hole, in which a support cable fixing member 400 is fixedly installed. The support cable fixing member 400 has a through-hole. The flexible support cable 300 is passed through the center hole and fixedly connected to the support cable fixing member 400. The connection between the flexible support cable 300 and the fixed beam 200 is achieved through the connection hole and the support cable fixing member 400. The structure is simple, easy to install, and the tightness of the flexible support cable 300 can be easily adjusted according to installation requirements.

[0049] During specific installation, the support cable fixing member 400 can be first installed in the connection hole, and then the flexible support cable 300 can be connected; alternatively, the support cable fixing member 400 can be first fixed on the flexible support cable 300, and then one end of the flexible support cable 300 is passed through the connection hole to enable the support cable fixing member 400 to enter the corresponding connection hole, thereby achieving the installation of the support cable fixing member 400.

[0050] Optionally, in this embodiment, the support cable fixing member 400 is fixedly connected to the flexible support cable 300 by crimping. During installation, a special crimping tool can be used to crimp the support cable fixing member 400, and the support cable fixing member 400 is fixed to the flexible support cable 300 by squeezing and deforming the support cable fixing member 400.

[0051] Further, continue to refer to Figure 5 , a circular flange 410 can be provided at one end of the support cable fixing member 400, and the circular flange 410 abuts against the fixed beam 200. By providing the circular flange 410, the risk of the support cable fixing member 400 disengaging from the connection hole can be reduced, the connection strength between the support cable fixing member 400 and the fixed beam 200 can be improved, and further the reliability of the fastening work of the support cable fixing member 400 on the flexible support cable 300 can be improved.

[0052] Optionally, continue to refer to Figure 5 , the fixed beam 200 is in a "U" shape, connection holes are provided on both opposite side walls of the fixed beam 200, one support cable fixing member 400 is installed in each connection hole, and the two support cable fixing members 400 on the same fixed beam 200 are connected to the same flexible support cable 300 or are respectively connected to two flexible support cables 300. That is, when multiple fixed beams 200 share one flexible support cable 300, the flexible support cable 300 passes through the two support cable fixing members 400 of the same fixed beam 200; when one flexible support cable 300 is provided between every two adjacent fixed beams 200, the two support cable fixing members 400 on the same fixed beam 200 are used to respectively fix the two flexible support cables 300.

[0053] By setting the fixed beam 200 in a "U" shape, the fixed beam 200 can be applicable to different arrangement modes of the flexible support cable 300, the flexibility of the assembly of the photovoltaic module bearing device is improved, and the structure is simple and convenient for processing.

[0054] Optionally, the fixed beam 200 can be a "U" shaped purlin.

[0055] Further, continue to refer to Figure 5 , the top plate of the "U" shaped fixed beam 200 is used to be connected to the frame

[0056] Optionally, the top plate of the “X-shaped” fixed beam 200 can be connected to the frame 11 by bolt connection. The bolt connection structure is simple and easy to install and disassemble.

[0057] This embodiment also provides a photovoltaic tracking bracket, comprising a drive device, columns, and the aforementioned photovoltaic module support device. The main beam 100 of the photovoltaic module support device is disposed on top of several columns, and the drive device is used to rotate the main beam 100 to ensure that the photovoltaic module 10 receives maximum sunlight.

[0058] It is understandable that the driving device can drive the main beam 100 to rotate around the axis of the main beam 100 itself, or can drive the main beam 100 to rotate in other directions, as long as the photovoltaic assembly 10 is always facing the sunlight.

[0059] Since the photovoltaic tracking bracket adopts the above-mentioned photovoltaic component bearing device, it has a strong ability to resist wind loads and a low failure rate. In addition, it is simple to install and has low installation and maintenance costs.

[0060] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
