Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic equipment technology, and more specifically, relates to a photovoltaic flexible support component and a photovoltaic system having the same. Background Technology

[0002] In certain applications, flexible photovoltaic (PV) supports require large spans or high stability. Existing technologies typically achieve this by increasing the structural stiffness (K), such as by increasing the number of cables or using arched cables. However, as the span increases, the number of cables increases dramatically, and arched cables are limited by factors such as space constraints, structural complexity, and cost. If the structural stiffness is insufficient, the structure will resonate under dynamic wind loads. If the structural stiffness is insufficient, increasing damping can also control the amplitude of the structural response. Several existing technologies have attempted to address these issues by increasing damping, for example:

[0003] (1) Patent application CN214412631U provides damping for the cable structure by adding a damper at the mid-span, with one end of the damper fixed to the ground. However, the purpose of large-span photovoltaic flexible support is to achieve a large span, so there is no need to provide a foundation for fixation at the mid-span. Therefore, this solution is not suitable for some application scenarios.

[0004] (2) The patent application with application number 202421155786.X fixes the lower end of the damper to the column. Although this avoids the problem of adding a foundation for fixing in the middle of the span, the upper end of the damper cannot be connected to the middle of the span because the span of the photovoltaic flexible support is very large. This will result in the damping effect being unsatisfactory.

[0005] (3) A tuned mass damping device is used in the patent application with application number 202320754273.X / 202310366463.9. A tuned mass damping device is an energy-absorbing mechanism that includes mass characteristics, stiffness characteristics, and damping characteristics. Matching the parameters of this device with the dynamic parameters of the structure can achieve good energy absorption (damping) characteristics. Tuned mass damping devices have been maturely used in super high-rise buildings, but there are still some disadvantages in applying this device to photovoltaic flexible supports, including: ① Since the device includes mass characteristics, it will inevitably increase the mass of the structure, resulting in a larger sag of the structure and increasing the structural strength requirements. ② It causes the photovoltaic module array to sag, affecting the power generation. ③ The increased mass and damping increase the natural period of the structure according to the dynamic formula, which is detrimental to the structure in the design of photovoltaic flexible supports. ④ The tuned mass damping device is suspended below the structure, and the device is easily thrown up and hit the photovoltaic modules when the structure vibrates.

[0006] (4) The patent application with application number 202320754273.X / 202310366463.9 also provides a solution to achieve vibration reduction by adding a damper between two rows of flexible photovoltaic supports. However, this solution also has disadvantages: ① Photovoltaic modules are generally laid horizontally, which may result in a certain angle. Wind loads are generally perpendicular to the photovoltaic modules, so the structure vibrates approximately vertically. Under this geometric positional relationship, the angle between the damper and the direction of structural motion is not ideal, affecting the damping effect. ② The damper blocks the modules from absorbing sunlight and generating electricity.

[0007] It is evident that there is currently no effective technical solution to the aforementioned technical problems, thus requiring improvement. Utility Model Content

[0044] The following is a detailed description of a photovoltaic flexible support assembly 100 according to an embodiment of the present invention, with reference to the accompanying drawings.

[0045] like Figures 1 to 9 As shown, the photovoltaic flexible support assembly 100 according to an embodiment of the present invention includes an upper mounting member 10, a lower mounting member 20, and at least one damping member 30.

[0046] Specifically, the upper mounting member 10 includes at least one upper cable 11 extending horizontally, the upper cable 11 being configured to mount the photovoltaic module 200. The lower mounting member 20 includes at least one lower cable 21 disposed below the upper mounting member 10, and at least one damping member 30 disposed between the upper cable 11 and the lower cable 21. The upper end of the damping member 30 is connected to the upper cable 11, and the lower end of the damping member 30 is connected to the lower cable 11. The axis of the damping member 30 forms a first angle α with the axis of the upper cable 11, and the axis of the damping member 30 forms a second angle β with the axis of the lower cable 21, wherein 80° < α < 100° and 80° < β < 100°.

[0047] In other words, the photovoltaic flexible support assembly 100 according to this embodiment of the present invention mainly consists of an upper mounting member 10 for a photovoltaic module 200, a lower mounting member 20 disposed below the upper mounting member 10, and a damping member 30 disposed between the upper mounting member 10 and the lower mounting member 20. The upper mounting member 10 may be composed of multiple upper cables 11 suitable for mounting the photovoltaic module 200, and at least one upper cable 11 may extend horizontally to facilitate the installation of the photovoltaic module 200. The lower mounting member 20 includes at least one lower cable 21, which is disposed below the upper mounting member 20, preferably below the corresponding upper cable 11.

[0048] A damping element 30 is disposed between the corresponding upper cable 11 and lower cable 21. The damping element 30 is generally formed as a columnar structure extending in the vertical direction, thereby forming a first angle and a second angle, which are close to right angles, with the upper cable 11 and the lower cable 21, respectively. The upper end of the damping element 30 is connected to the upper cable 11, and the lower end of the damping element 30 is connected to the lower cable 21. The lower cable 21 serves as the lower support structure of the damping element 30, providing a support point for the lower end of the damping element 30. Through the cooperation of the damping element 30 and the lower cable 21, the overall structural vibration energy of the photovoltaic flexible support assembly 100 can be dissipated, thereby controlling the overall vibration of the photovoltaic flexible support assembly 100.

[0049] It should be noted that the upper cable 11 and the lower cable 21 can adopt conventional cable structures with a certain degree of elasticity, thereby avoiding a rigid connection between the damping element 30 and the upper cable 11 and the lower cable 21. The two ends of the upper cable 11 and the lower cable 21 can be installed or fixed by the fixing post 60, or by other installation structures, which are not limited here. In addition, although the lateral stiffness of the upper cable 11 and the lower cable 21 with a certain degree of elasticity is relatively low, making the support point of the lower cable 21 for the damping element 30 not a rigid support point, and the damping effect will not be as good as that of a rigid support point, this flexible support point can still achieve an effective damping effect. Furthermore, based on this support point as an elastic foundation, structures such as stiffening members and mass members can be further configured to achieve better damping and energy absorption effects through reasonable design.

[0050] Therefore, according to the photovoltaic flexible support assembly 100 of this utility model embodiment, by setting an additional pull cable 21 below the upper mounting member 10 as the lower mounting member 20, the pull cable 21 can provide a support point for the lower end of the damping member 30. Through the cooperation of the damping member 30 and the lower mounting member 20, the overall vibration energy of the photovoltaic flexible support assembly 100 can be dissipated, thereby controlling the vibration of the overall structure.

[0051] In some specific embodiments of this utility model, the upper mounting component 10 includes at least two parallel upper cables 11, and the lower mounting component 20 includes at least two parallel lower cables 21. Each lower cable 21 is located below the corresponding upper cable 11, and a plurality of damping components 30 are provided between each upper cable 11 and the corresponding lower cable 21.

[0052] In other words, the upper mounting component 10 and the lower mounting component 20 can each be composed of two cables. That is, the upper mounting component 10 includes two upper cables 11, and the lower mounting component 20 includes two lower cables 21. The two upper cables 11 are arranged in parallel, and the two lower cables 21 are also arranged in parallel and are located below the upper cables 11 respectively. Each upper cable 11 and the corresponding lower cable 21 are provided with a damping element 30. The damping element 30 can include multiple elements, and the specific number can be adjusted according to the length of the upper cable 11 and the lower cable 21 and the distance between them.

[0053] Therefore, by setting multiple upper cables 11, multiple lower cables 21, and multiple damping components 30, the overall vibration energy dissipation of the photovoltaic flexible support module 100 can be further improved.

[0054] Optionally, according to some embodiments of the present invention, the pull cable 21 is formed as a horizontal cable extending in the horizontal direction, and preload is applied to both ends of each horizontal cable.

[0055] In other words, such as Figure 1 and Figure 2 As shown, in this embodiment, both the upper cable 11 and the lower cable 21 are formed as horizontal cables extending in the horizontal direction. Both ends of the upper cable 11 and the lower cable 21 are fixedly installed via fixing posts 60, and a preload is applied during installation to provide a certain supporting force. Therefore, the upper cable 11 and the lower cable 21 of this structure are easy to install and provide good support for the damping element 30, thereby ensuring the effective dissipation of the overall vibration energy of the photovoltaic flexible support assembly 100.

[0056] In some specific embodiments of this utility model, the horizontal cables include multiple horizontal cables, which are interwoven to form a cable net.

[0057] In other words, the upper mounting component 10 may include multiple upper cables 11, and the lower mounting component 20 may include multiple lower cables 21. The multiple upper cables 11 are interconnected in an interlaced manner to form a cable net, and the multiple lower cables 21 are also interconnected in an interlaced manner to form a cable net. Multiple damping elements 30 are provided between the cable net formed by the multiple upper cables 11 and the cable net formed by the multiple lower cables 21. Thus, the cable net structure composed of multiple cables can effectively improve the stability of the cables, thereby ensuring the support effect for the damping elements 30 while further improving the effect of dissipating the overall vibration energy of the photovoltaic flexible support module 100.

[0058] Optionally, in some specific embodiments of this utility model, the pull cable 21 is formed as an arc-shaped pull cable that is concave downward or convex upward in the horizontal direction.

[0059] Specifically, such as Figure 3 , Figure 4 and Figure 7 As shown, in this embodiment, since the photovoltaic module 200 does not need to be installed on the pull cable 21, the pull cable 21 does not necessarily need to be set as a horizontal structure. The pull cable 21 can also be set as an arc-shaped cable with a certain curvature, instead of a horizontal cable extending in the horizontal direction. As a result, the arc-shaped pull cable 21 has higher stiffness, and the structural design of the arc-shaped cable can provide more effective fixation and support for the damping element 30, thereby further improving the effect of dissipating vibration energy.

[0060] According to one embodiment of the present invention, the pull cable 21 is formed as a transverse pull cable that is recessed downward in the horizontal direction, and the lower mounting member 20 also includes a plurality of longitudinal pull cables 22 that are protruding upward in the horizontal direction, each longitudinal pull cable 22 being cross-connected with a plurality of transverse pull cables.

[0061] In other words, such as Figure 3As shown, the lower mounting component 20 includes multiple pull cables 21 and longitudinal cables 22. The pull cables 21 extend laterally and are recessed downward in the horizontal direction, while the longitudinal cables 22 extend longitudinally and are protruding upward in the horizontal direction. Each longitudinal cable 22 crosses multiple pull cables 21 and is connected to each pull cable 21 to form a cable net structure, thereby effectively improving the support effect on the damping component 30.

[0062] In some other specific embodiments of this utility model, each pull cable 21 includes a downwardly recessed drooping cable 211 and an upwardly protruding arched cable 212, with the arched cable 212 located above the drooping cable 211 and positioned opposite to it.

[0063] Specifically, such as Figure 4 As shown, in this embodiment, each pull cable 21 is composed of a drooping cable 211 and an arched cable 212. The drooping cable 211 is concave downwards relative to the horizontal direction, and the arched cable 212 is convex upwards relative to the horizontal direction. The arched cable 212 is located above the drooping cable 211, and its top is connected to the bottom of the drooping cable 211. The lower end of the damping member 30 is connected to both the drooping cable 211 and the arched cable 212. Therefore, the pull cable 21 with this structure can further improve the support effect on the damping member 30.

[0064] Optionally, according to some embodiments of the present invention, the photovoltaic flexible support assembly 100 further includes: a mass member 40, which is disposed at the lower end of the damping member 30 or on the pull cable 21, and the natural frequency of the mass member 40 and the pull cable 21 is less than the natural frequency of the pull cable 11 and the photovoltaic assembly 200.

[0065] Specifically, such as Figure 5 , Figure 6 , Figure 7 and Figure 9 As shown, in this embodiment, a mass member 40 is also provided at the lower end of the damping member 30 or on the pull cable 21. The mass member 40 is constrained by the pull cable 21, which can reduce the possibility of the mass member 40 being thrown off and touching other structures. If a conventional structure mass member 40 is used, that is, the mass member 40 is added directly below the damping member 30, it will increase the deflection of the upper structure. However, after adding the pull cable 21 structure, the weight of the mass member 40 is borne by the lower structure, and the upper structure does not experience additional deflection.

[0066] It should be noted that Figure 2 , Figure 6 , Figure 8 and Figure 9The schematic diagram shown is a force structure diagram of the photovoltaic flexible support assembly 100. Since the upper cable 11 and the lower cable 21 have a certain elasticity, they are shown in the figure in a structure similar to a spring. The assembly positions of the photovoltaic assembly 200, damping component 30, mass component 40, etc. are based on the assembly positions shown in other figures.

[0067] In some specific embodiments of this utility model, the photovoltaic flexible support assembly 100 further includes: an elastic connector 50, which is disposed between the upper mounting member 10 and the lower mounting member 20. The elastic connector 50 and the damping member 30 are arranged side by side, and the upper end of the elastic connector 50 is connected to the upper cable 11, and the lower end of the elastic connector 50 is connected to the lower cable 21.

[0068] Specifically, such as Figure 8 and Figure 9 As shown, in this embodiment, in addition to the damping element 30, an elastic connector 50 is also provided between the upper cable 11 and the lower cable 21. The elastic connector 50 and the corresponding damping element 30 are arranged side by side, with the upper end of the elastic connector 50 connected to the upper cable 11 and the lower end of the elastic connector 50 connected to the lower cable 21. When a mass member 40 is provided at the lower end of the damping element 30 or on the lower cable 21, the lower end of the elastic connector 50 can also be connected to the mass member 40. Therefore, by providing the elastic connector 50 between the upper cable 11 and the lower cable 21, the structural deflection of the upper mounting structure, i.e., the upper cable 21, can be effectively reduced. In some embodiments, the elastic connector 50 is initially in a compressed state, and the elastic connector 50 lifts the upper mounting structure, reducing the sag of the upper mounting structure, thereby effectively reducing the deflection of the upper mounting structure.

[0069] This utility model also proposes a photovoltaic system, including a photovoltaic flexible support assembly 100 according to any of the above embodiments. Since the photovoltaic flexible support assembly 100 according to the above embodiments of this utility model has the aforementioned technical effects, the photovoltaic system according to the embodiments of this utility model also has corresponding technical effects. That is, by setting an additional pull cable 21 below the upper mounting member 10 as a lower mounting member 20, the pull cable 21 can provide a support point for the lower end of the damping member 30. Through the cooperation of the damping member 30 and the lower mounting member 20, the overall vibration energy of the photovoltaic flexible support assembly 100 can be dissipated, thereby controlling the vibration of the overall structure.
