[0010] Furthermore, the vibration reduction assembly also includes two second damping spring links, each of the counterweight blocks is connected to the corresponding end of the cross bar via a second damping spring link, and the second damping spring link extends coaxially with the cross bar.

[0011] Furthermore, the counterweight blocks are all configured as streamlined structures.

[0012] Further, the first damping spring connecting rod is detachably connected to the connecting assembly; and / or the second damping spring connecting rod is detachably connected to the cross bar.

[0013] Furthermore, the vibration reduction assembly further includes a limiting sleeve, which is sleeved on the outside of the first damping spring link and / or the second damping spring link to limit the movement of the first damping spring link and / or the second damping spring link along the extension direction thereof.

[0018] Beneficial effects of the present invention:

[0019] The present invention provides a load-bearing cable vibration reduction device and a flexible photovoltaic bracket, comprising a connecting assembly, a vibration reduction assembly and a counterweight assembly; through the mutual cooperation among the connecting assembly, the counterweight assembly and the vibration reduction assembly, when the load-bearing cable on the flexible photovoltaic bracket vibrates, the load-bearing cable vibration reduction device also vibrates accordingly, and since the load-bearing cable vibration reduction device has a large mass and a low vibration reduction frequency, the load-bearing cable vibration reduction device is coupled with the vibration of the load-bearing cable, so that the vibration energy of the system is gradually transmitted from the load-bearing cable to the load-bearing cable vibration reduction device. When the load-bearing cable vibration reduction device is suspended on the load-bearing cable, the first damping spring link in the vibration reduction assembly can maintain a vertical state through the gravity of the counterweight assembly.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] Please refer to Figures 1 to 3As shown, the present invention provides a load-bearing cable vibration reduction device, which can absorb or weaken the vibration energy of the load-bearing cable, change the swing frequency, effectively control the disturbance of the load-bearing cable, thereby avoiding the problem of hidden cracks, improving the windproof effect, adapting to the needs of different seasons and different usage scenarios, and extending the service life of the flexible photovoltaic bracket. The load-bearing cable vibration reduction device includes a connecting component 1, a vibration reduction component 2 and a counterweight component 3, wherein one end of the connecting component 1 is detachably connected to the load-bearing cable so that the load-bearing cable vibration reduction device is suspended on the load-bearing cable; the vibration reduction component 2 includes a first damping spring connecting rod 21, one end of the first damping spring connecting rod 21 is connected to the end of the connecting component 1 away from the load-bearing cable; the counterweight component 3 is detachably connected to the end of the first damping spring connecting rod 21 away from the connecting component 1, and the counterweight component 3 is evenly and symmetrically distributed along the central axis direction of the first damping spring connecting rod 21. The counterweight component 3 can keep the first damping spring connecting rod 21 in a vertical state through its gravity.

[0032] Through the mutual cooperation between the connecting component 1, the counterweight component 3 and the vibration reduction component 2, when the load-bearing cable vibrates, the load-bearing cable vibration reduction device also vibrates. Since the load-bearing cable vibration reduction device has a large mass and its vibration reduction frequency is low, the load-bearing cable vibration reduction device is coupled with the vibration of the load-bearing cable, so that the vibration energy of the system is gradually transferred from the load-bearing cable to the load-bearing cable vibration reduction device. When the load-bearing cable vibration reduction device is suspended on the load-bearing cable, the first damping spring link 21 in the vibration reduction assembly 2 can maintain a vertical state through the gravity of the counterweight assembly 3. Driven by the gravity of the counterweight assembly 3, the first damping spring link 21 can absorb the vibration energy of the load-bearing cable in the vertical direction through its elastic characteristics, and convert it into the expansion and contraction movement of the spring, thereby reducing the shaking of the rope; at the same time, the first damping spring link 21 has a certain damping characteristic, and utilizes the damping characteristic to convert the vibration energy into heat energy or other energy forms, thereby reducing the intensity of the vibration; therefore, the damping characteristic and elastic expansion and contraction of the first damping spring link 21 will generate a reaction force in the opposite direction of the vibration direction of the load-bearing cable. This reaction force helps the load-bearing cable to suppress excessive vibration, limit its swing range, reduce the generation of disturbance, and thus protect the stability of the entire photovoltaic system. In addition, the gravity of the counterweight assembly 3 keeps the first damping spring link 21 vertical, and also stabilizes the swing frequency of the load-bearing cable. The inertia of the counterweight assembly 3 is used to generate internal friction on the first damping spring link 21 of the vibration reduction assembly 2. This friction can effectively consume most of the vibration energy of the load-bearing cable. The counterweight assembly 3 is affected by air resistance during movement, which helps to control the resonant frequency of the system at a lower level and reduce the resonance phenomenon caused by wind load. The counterweight assembly 3 and the vibration reduction assembly 2 are fixed to the load-bearing cable through the connecting assembly 1. The connection will generate contact friction when vibrating, which can reduce the intensity of vibration transmission and offset part of the vibration energy by reflecting energy. Therefore, the design of the load-bearing cable vibration reduction device combines multiple energy consumption methods such as reaction force, inertia, internal friction, air damping and connection, so that the energy in the flexible photovoltaic support system is continuously consumed and dispersed during breeze vibration, effectively reducing the vibration intensity of the system in a breeze environment, ensuring that the load-bearing cable maintains a low shaking amplitude, improving the stability of the system and extending its service life. At the same time, the counterweight assembly 3 and the vibration reduction assembly 2 are detachably connected and evenly and symmetrically distributed along the central axis direction of the first damping spring connecting rod 21. Different counterweight masses can be introduced into the flexible photovoltaic support system to facilitate changing the natural frequency of the system. The counterweight of the counterweight assembly 3 can be adjusted according to actual use needs and wind speeds in different seasons to ensure the balance and stability of the system, which helps to evenly exert the vibration reduction effect.

[0033] like Figure 2As shown, specifically, the counterweight assembly 3 includes a cross bar 31 and two counterweight blocks 32, the middle portion of the cross bar 31 is connected to the first damping spring link 21, and the counterweight blocks 32 are detachably connected to both ends of the cross bar 31; by connecting the middle portion of the cross bar 31 to the first damping spring link 21, the balance of the counterweight assembly 3 is improved, and the symmetrically distributed counterweight blocks 32 help to balance the gravity distribution of the entire load-bearing cable vibration reduction device, produce a balanced damping effect during vibration, and enhance the vibration energy absorption capacity of the vibration reduction assembly 2; the counterweight blocks 32 at both ends of the cross bar 31 are detachably connected, which is convenient for adjusting the weight of the counterweight blocks 32 according to actual needs or replacing counterweight blocks 32 of different specifications, and flexibly adjusting the vibration reduction effect and vibration frequency. In order to increase the stability of the connection between the cross bar 31 and the first damping spring link 21, the cross bar 31 and the first damping spring link 21 can be connected by bolts or pins, which can ensure that the counterweight assembly 3 is tightly combined with the first damping spring link 21, provide a stable support effect, prevent the counterweight assembly 3 from loosening or falling off, and improve the stability and reliability of the load-bearing cable vibration reduction device; at the same time, the connection method of bolts and pins is simple, making the installation and disassembly process quick and easy, which is conducive to replacing the type of counterweight assembly 3 according to actual needs, and improving the adaptability and versatility of the load-bearing cable vibration reduction device.

[0034] In other embodiments, a three-way sleeve is also provided on the cross bar 31, and the three-way sleeve can connect the first damping spring connecting rod 21 and the cross bar 31, thereby increasing the rigidity of the structure and making the connection between the two more stable. Furthermore, threaded structures are provided at both ends of the cross bar 31, and a threaded structure matching the same is provided inside the counterweight 32. The cross bar 31 is threadedly connected to the counterweight 32, and the threaded connection can not only ensure the stability of the connection between the two, but also facilitate the disassembly and replacement of the counterweight 32. In other embodiments, the counterweight 32 and the cross bar 31 can be connected by snap-fit ​​or clamping, which is not specifically limited here.

[0035] Continue as Figure 2As shown, in order to better absorb vibration energy from different directions, in some embodiments, the vibration reduction assembly 2 further includes a second damping spring link 22, which is symmetrically arranged on both sides of the cross bar 31 away from the first damping spring link 21 along the extension direction of both ends of the central axis of the cross bar 31; the second damping spring link 22 is connected to a counterweight block 32 at one end away from the cross bar 31; after the vibration reduction assembly 2 is added with the second damping spring link 22, the second damping spring link 22 is symmetrically arranged on both sides of the cross bar 31 and the first damping spring link 21 is vertically arranged, the first damping spring link 21 mainly absorbs vibration energy from the vertical direction, and the second damping spring link 22 mainly absorbs vibration energy from the horizontal direction. The two form a multi-layer vibration reduction structure, which can absorb vibration energy from different directions at the same time, and help the load-bearing cable vibration reduction device to respond quickly when vibration occurs; the counterweight block 32 is connected through the second damping spring link 22, so that it is far away from the main body of the cross bar 31, effectively lengthening the distance of gravity, forming a lever structure, and helping to enhance the vibration reduction effect of the counterweight block 32. Further, the counterweight block 32 is set to a streamlined structure, wherein the streamlined structure can contact with the air more smoothly, reduce unnecessary resistance and interference, and can effectively reduce the air resistance of the counterweight block 32 when it vibrates or moves, thereby reducing wind resistance and vortex effect, and reducing additional vibration or sway caused by the external environment. It can be understood that the counterweight block 32 can be, but is not limited to, set to an elliptical structure, etc., which is not specifically limited here.

[0036] like Figure 1 As shown, in order to increase the flexibility of the vibration reduction assembly 2, in some embodiments, the first damping spring link 21 is detachably connected to the connecting assembly 1; and / or the second damping spring link 22 is detachably connected to the cross bar 31; through the detachable design of the first damping spring link 21 and / or the second damping spring link 22, the vibration reduction assembly 2 can not only adjust the weight of the counterweight block 32, but also adjust the damping characteristics of the load-bearing cable vibration reduction device by replacing the first damping spring link 21 and / or the second damping spring link 22 with different stiffness. It can be understood that the two ends of the first damping spring link 21 and / or the second damping spring link 22 can be detachably connected in the form of bolts, pins or buckles.

[0037] In order to enhance the stability of the shock absorbing assembly 2, in some embodiments, the shock absorbing assembly 2 also includes a limiting sleeve, which is sleeved on the outside of the first damping spring link 21 and / or the second damping spring link 22 to limit the movement of the first damping spring link 21 and / or the second damping spring link 22 along their extension direction; wherein the limiting sleeve effectively guides the first damping spring link 21 and / or the second damping spring link 22 to move in a fixed direction, ensuring that they maintain linear extension and contraction, avoiding unnecessary lateral swing, thereby optimizing the shock absorbing effect.

[0038] In order to facilitate the disassembly of the load-bearing cable vibration reduction device and the load-bearing cable, in some embodiments, the connecting component 1 includes a connecting member 11 and a fastener 12, one end of the connecting member 11 is detachably connected to the load-bearing cable, the other end of the connecting component 1 is connected to one end of the fastener 12, and the other end of the fastener 12 is connected to the first damping spring link 21; wherein the connecting member 11 can easily realize the connection or disconnection of the vibration reduction component 2 and the flexible photovoltaic bracket, and the fastener 12 can ensure the stability of the connection between the connecting component 1 and the vibration reduction component 2, and can withstand forces and vibrations under different working conditions. The connection method enhances the ability of the components to work together, which helps to improve the performance of the overall system.

[0039] Combination Figure 1 and Figure 3 As shown, specifically, the connector 11 is a clamp structure, the clamp includes a locking portion and two annular hoop bodies, the two annular hoop bodies are hinged at one end close to the fastener 12, and the other ends of the two annular hoop bodies are locked by a detachable locking portion, and the annular hoop bodies can clamp the flexible photovoltaic bracket; the clamp structure allows the load-bearing cable vibration reduction device to be quickly and conveniently installed and removed without the need for additional tools. The operator only needs to open the clamp, clamp it on the flexible photovoltaic bracket, and then lock it. This convenience greatly improves the installation efficiency; in addition, the clamp also includes a locking portion, which ensures that the connector 11 will not accidentally loosen during use, thereby improving the durable and reliable connection between the connector 11 and the load-bearing cable. The locking portion can be a bolt structure, wherein the bolt structure can adjust the clamping force of the two annular solids on the load-bearing cable, and can adapt to different types of load-bearing cables. In order to further stabilize the position of the load-bearing cable vibration reduction device on the flexible photovoltaic bracket. In addition, the inner wall of the annular hoop is provided with an anti-slip member; the anti-slip member provides additional friction, enhances the clamping effect between the hoop and the flexible photovoltaic bracket, increases the friction coefficient of the contact surface, and makes the hoop less likely to slide when locked, thereby improving the stability of the connection, especially under external forces such as wind, the load-bearing cable vibration reduction device can be kept in a fixed position. Among them, the anti-slip member can be, but is not limited to, a silicone pad, etc., which is not specifically limited here.

[0040] In other embodiments, the connecting member 11 can also be designed as a locking structure, which can also realize a detachable connection between the load-bearing cable vibration reduction device and the load-bearing cable.

[0041] The present invention also provides a flexible photovoltaic bracket, comprising a load-bearing cable, a limit member and a load-bearing cable vibration reduction device in any of the above-mentioned embodiments, wherein a plurality of limit members are arranged in sequence at intervals along the extension direction of the load-bearing cable, and a connecting assembly 1 can be selectively detachably connected to any limit member; wherein the cooperation between the load-bearing cable and the limit member can ensure a stable connection between the flexible photovoltaic bracket and the load-bearing cable vibration reduction device, the limit member can limit the sliding of the load-bearing cable vibration reduction device on the cableway, and a plurality of limit members are arranged in sequence at intervals along the load-bearing cable, so that the load-bearing cable vibration reduction device can adjust the position of the suspended load-bearing cable according to actual needs, thereby improving the flexibility of the device. Through the mutual cooperation between the connecting component 1, the counterweight component 3 and the vibration reduction component 2, when the load-bearing cable on the flexible photovoltaic bracket vibrates, the load-bearing cable vibration reduction device also vibrates. Since the load-bearing cable vibration reduction device has a large mass and a low vibration reduction frequency, the load-bearing cable vibration reduction device is coupled with the vibration of the load-bearing cable, so that the vibration energy of the system is gradually transmitted from the load-bearing cable to the load-bearing cable vibration reduction device, effectively controlling the disturbance of the load-bearing cable, thereby avoiding the problem of hidden cracks, improving the wind protection effect, and extending the service life of the flexible photovoltaic bracket; at the same time, the counterweight component 3 and the vibration reduction component are detachably connected, and different counterweight masses can be introduced into the flexible photovoltaic bracket system, which is convenient for changing the natural frequency of the system.
