[0002] A photovoltaic bracket is a structural device used to support photovoltaic modules, providing stable support for a photovoltaic power generation system. A flexible vibration damping device is a device specifically designed to reduce or eliminate the adverse effects on a structure caused by factors such as wind-induced vibration. In a photovoltaic system, a photovoltaic bracket, especially a flexible photovoltaic bracket, is prone to be affected by wind-induced vibration during use. The flexible vibration damping device can effectively be combined with the photovoltaic bracket and installed at specific parts of the flexible photovoltaic bracket to eliminate and weaken the vibration on the steel strands, protect the structural safety of the photovoltaic bracket, and improve the stability and reliability of the entire photovoltaic system.

[0003] In the prior art, some photovoltaic brackets are usually used to support steel strands and photovoltaic brackets. Since they are installed at a relatively high position, they are easily affected by the high-altitude air flow, causing the steel strands to shake, and then causing the photovoltaic panels to shake. Continuous vibration will also change the installation angle of the photovoltaic panels, resulting in their inability to always receive sunlight at the optimal angle, thereby reducing the photovoltaic power generation efficiency. Moreover, long-term vibration will also cause problems such as cracks in the battery chips and loosening of the solder joints, affecting the service life and performance of the photovoltaic modules. Therefore, in view of the above deficiencies, a vibration damping device for a flexible photovoltaic bracket is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a vibration damping device for a flexible photovoltaic bracket is proposed, aiming to improve the problem that in the prior art, the steel strands are affected by the air flow, vibrate, and then reduce the overall service life.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A vibration damping device for a flexible photovoltaic bracket, including two support columns. The outer top ends of the support columns are connected with support components. On the adjacent sides of the two support components, two steel strands are fixedly connected. A plurality of photovoltaic panels are fixedly connected to the outer parts of the two steel strands. A locking component is fixedly connected to the outer part of the steel strand. The bottom end of the locking component is fixedly connected with a connecting rod. Two counterweights are fixedly connected to the outer part of the connecting rod. The bottom end of the connecting rod is fixedly connected with a force-bearing plate. A damper is fixedly connected to the bottom end of the force-bearing plate. An adapter rod is rotatably connected to the inner part of one side of the force-bearing plate. On the adjacent sides of the two support columns, load-bearing plates are fixedly connected. A sliding hole is opened at the top end of the load-bearing plate. A fixing rod is fixedly connected to the inside of the sliding hole. A spring is sleeved on the outer part of the fixing rod. A sliding block is rotatably connected to the outer part of the bottom end of the adapter rod.

[0006] Further, the support assembly includes two support rods. The adjacent sides of every two support rods are fixedly connected to the outer top end of the support column. The tops of the two support rods are fixedly connected with a support plate, and the adjacent sides of the two support plates are respectively fixedly connected to the left and right sides of the two steel strands.

[0007] Further, the locking assembly includes two hoop fasteners. Bolts are threadedly connected to the inner parts of the front and rear sides of the hoop fasteners, and the bottom ends of the hoop fasteners are fixedly connected to the top end of the connecting rod.

[0008] Further, the bottom end of the damper is fixedly connected to the top end of the load-bearing plate.

[0009] Further, one end of the spring is fixedly connected to one side inside the sliding hole, and the other end of the spring is fixedly connected to one side of the sliding block.

[0011] Further, the bottom end of the support column is fixedly connected with a base.

[0012] The utility model has the following beneficial effects:

[0013] In the utility model, when wind-induced vibration acts on the steel strand, the combination of the spring buffer and the damper can generate a movement with a vibration phase opposite to that of the steel strand. The spring is compressed when the steel strand vibrates, stores and releases energy, and generates a reverse elastic force. The damper controls the movement speed of the spring by consuming vibration energy to prevent excessive oscillation. This movement with a opposite phase can effectively cancel out the vibration energy on the steel strand, greatly reduce the vibration amplitude, and improve the overall service life.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Refer to Figures 1 to 3 , an embodiment provided by the present invention: a vibration damping device for a flexible photovoltaic support, including two support columns 1, which provide stable vertical support for the entire device, ensuring that the device can maintain a stable posture under various environmental conditions. The outer top end of the support column 1 is connected with a support assembly. The support assembly includes two support rods 2. The support rods 2 strongly support the upper structure from both sides, evenly transmitting the pressure from above to the support column 1. At the same time, its specific connection method ensures the firmness of the connection, and it can withstand large external forces without loosening or deforming. The adjacent sides of every two support rods 2 are fixedly connected to the outer top end of the support column 1. The tops of the two support rods 2 are fixedly connected with a support plate 3. The adjacent sides of the two support plates 3 are respectively fixedly connected to the left and right sides of two steel strands 4. The adjacent sides of the two support assemblies are fixedly connected with two steel strands 4. The support plate 3 provides a broad support plane for the steel strands 4, dispersing the pressure brought by the steel strands 4, ensuring that the steel strands 4 are stably laid above it, and being able to withstand certain wind-induced vibrations and external impacts without obvious deformation or damage. A plurality of photovoltaic panels 5 are fixedly connected to the outer parts of the two steel strands 4. The two steel strands 4 cooperate with each other to jointly bear the weight and external forces of the photovoltaic panels 5, improving the load-bearing capacity and stability of the entire device. A locking assembly is fixedly connected to the outer part of the steel strand 4. The locking assembly ensures the firm and reliable connection between the steel strand 4 and other components, preventing the steel strand 4 from loosening or slipping under external forces such as wind-induced vibrations, and ensuring the structural stability of the entire device. The bottom end of the locking assembly is fixedly connected with a connecting rod 8;

[0022] The locking assembly includes two hoop clamps 6. Threaded bolts 7 are connected to the inner sides of the front and rear of the hoop clamp 6. The hoop clamp 6 tightly wraps around the outside of the steel strand 4 and is fastened by the bolts 7 on the inner sides of the front and rear. It can be adjusted according to the diameter of the steel strand 4 to ensure a tight fit between the hoop clamp 6 and the steel strand 4 without relative sliding or displacement. The bottom end of the hoop clamp 6 is fixedly connected to the top end of the connecting rod 8. The connecting rod 8 connects the hoop clamp 6 to the structure below, playing a role in transmitting force and displacement, making the steel strand 4 above and the vibration damping structure below form an integral whole to jointly cope with external forces such as wind-induced vibration;

[0023] Two counterweight blocks 9 are fixedly connected to the outside of the connecting rod 8. The counterweight blocks 9 increase the overall weight of the device, lower the center of gravity of the device, and improve the stability of the device. In the case of wind-induced vibration and the like, the inertial effect of the counterweight blocks 9 can offset a part of the external force and reduce the swaying amplitude of the device. The bottom end of the connecting rod 8 is fixedly connected to a force-receiving plate 10 to ensure stable and reliable force transmission. The bottom end of the force-receiving plate 10 is fixedly connected to a damper 11. In the case of wind-induced vibration and the like, the damper 11 reduces the vibration amplitude and duration of the device by consuming vibration energy. It can automatically adjust the magnitude of the damping force according to the frequency and amplitude of the vibration, enabling the device to quickly stabilize and protecting the photovoltaic panel 5 and other components from damage caused by vibration. One side of the force-receiving plate 10 is rotatably connected to a connecting rod 12. When the device vibrates, the connecting rod 12 can rotate along with the movement of the force-receiving plate 10 to transmit the force.

[0024] Refer to Figure 1 、 Figure 2 and Figure 4, on the adjacent sides of the two support columns 1, there are load-bearing plates 13 fixedly connected. The bottom end of the damper 11 is fixedly connected to the top end of the load-bearing plate 13, ensuring that the damper 11 will not displace or loosen during operation, and can stably play the role of vibration damping. A sliding hole 14 is provided at the top end of the load-bearing plate 13 to provide additional movement space. A fixed rod 15 is fixedly connected inside the sliding hole 14. A spring 16 is sleeved outside the fixed rod 15. When the device vibrates, the spring 16 can absorb and release energy through compression and stretching, playing a role in buffering and vibration damping. The bottom end outside of the connecting rod 12 is rotatably connected with a sliding block 17. One end of the spring 16 is fixedly connected to one side inside the sliding hole 14, and the other end of the spring 16 is fixedly connected to one side of the sliding block 17, ensuring that the spring 16 will not fall off or be misaligned during operation and can stably play its role. The outside of the sliding block 17 is slidably connected inside the sliding hole 14, and the inside of the sliding block 17 is slidably connected outside the fixed rod 15. Driven by the connecting rod 12, the sliding block 17 can slide along the fixed rod 15 inside the sliding hole 14, transmitting force to the spring 16 to realize the expansion and contraction of the spring 16 and the transmission of force. The rotatable connection method reduces friction and resistance during the force transmission process, improves the response speed and vibration damping effect of the device. The bottom end of the support column 1 is fixedly connected with a base 18. The base 18 increases the contact area with the ground, enables the support column 1 to stand more firmly on the ground, disperses the gravity and external forces borne by the device, and improves the stability of the device.

[0025] Working principle: When wind-induced vibration occurs, it first acts on the entire device supported by the two support columns 1. The base 18 at the bottom end of the support column 1 increases the contact area with the ground, disperses the gravity and external forces of the device, and ensures the stability of the device. The support components at the outer top ends of the support columns 1 start to play their roles. The two support rods 2 evenly transmit the upward pressure from both sides to the support column 1. The support plate 3 at its top end provides a broad support plane for the steel wire ropes 4. The multiple photovoltaic panels 5 fixed outside the two steel wire ropes 4 are responsible for converting solar energy into electrical energy. At the same time, the two steel wire ropes 4 jointly bear the weight and external forces of the photovoltaic panels 5, improving the load-bearing capacity and stability of the device.

[0026] The locking assembly on the steel strand 4 ensures a firm and reliable connection. The hoop 6 tightly wraps the steel strand 4 and is fastened by bolts 7 on the front and rear sides. The fit can be adjusted according to the diameter of the steel strand 4 to prevent the steel strand 4 from loosening or slipping under wind-induced vibration. The connecting rod 8 connected to the bottom end of the hoop 6 connects the upper steel strand 4 with the lower vibration-absorbing structure as a whole. The counterweight 9 outside the connecting rod 8 increases the overall weight of the device and lowers the center of gravity. During wind-induced vibration, its inertia can offset part of the external force and reduce the shaking amplitude of the device. The force-bearing plate 10 at the bottom of the connecting rod 8 transmits force to the damper 11 and the connecting rod 12 to ensure stable and reliable force transmission. The damper 11 consumes vibration energy during wind-induced vibration, reduces the vibration amplitude and duration of the device, and can automatically adjust the damping force according to the vibration frequency and amplitude to protect the photovoltaic panel 5 and other components from vibration damage. The connecting rod 12 rotates with the movement of the force-bearing plate 10 when the device vibrates to transmit the force.

[0027] At the same time, the loading plate 13 on the side close to the two support columns 1 provides an installation platform for components such as the damper 11 and the spring 16. The bottom end of the damper 11 is fixed to the top of the loading plate 13 to ensure that it does not move or loosen during operation. The sliding hole 14 opened at the top of the loading plate 13 provides a movement space for the sliding block 17. The fixed rod 15 in the sliding hole 14 provides a guide for the sliding block 17. The spring 16 is sleeved on the outside of the fixed rod 15, and absorbs and releases energy through compression and tension when the device vibrates, playing a buffering and vibration-absorbing role. The sliding block 17 rotatably connected to the bottom end of the connecting rod 12 slides along the fixed rod 15 in the sliding hole 14 under the drive of the connecting rod 12, and transmits force to the spring 16, thereby realizing the expansion and contraction of the spring 16 and the transmission of force. The two ends of the spring 16 are respectively fixed to one side of the inside of the sliding hole 14 and one side of the sliding block 17 to ensure that it does not fall off or dislocate during operation. The sliding connection between the sliding block 17, the sliding hole 14 and the fixing rod 15 reduces the friction and resistance during the force transmission process, thereby improving the response speed and vibration elimination effect of the device.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
