Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, and in particular to a photovoltaic support vibration damping device and its installation method. Background Technology

[0002] As a crucial component of photovoltaic (PV) power generation systems, photovoltaic (PV) mounting systems support and reliably secure PV modules. Besides bearing gravity loads, they must also withstand external forces from the natural environment, such as wind, snow, and seismic loads. The core characteristics of PV mounting systems are safety, reliability, adaptability, and cost-effectiveness. Since large-scale PV deployments are often carried out in open areas such as deserts, Gobi, and water surfaces, where wind loads are significant and structural deformation caused by wind is particularly pronounced, the PV mounting system must possess strong resistance to wind-induced vibrations. It must be able to control deformation and maintain stability under wind suction and pressure conditions, ensuring high operating efficiency for the PV modules.

[0003] Dampers, as efficient energy-dissipating and vibration-damping devices, can effectively reduce the response of components under vibration. They can also be used in large-span flexible cable structures to further reduce the deformation of the flexible cables and improve the stability of the structure. However, existing dampers generally have drawbacks such as unadjustable damping and a single energy dissipation method, making it difficult to meet the complex requirements of different natural frequencies in various regions of photovoltaic support flexible cable structure systems.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] To facilitate understanding of this embodiment, a detailed description of a photovoltaic support vibration reduction device disclosed in this embodiment of the invention will be provided first, see [link to relevant documentation]. Figures 1 to 4 As shown, the photovoltaic support vibration damping device may include: a mass block 1, a damper 2, a first connecting horizontal bar 3, a first connecting vertical bar 6, and a second connecting rod; the mass block 1 is disposed on the first connecting horizontal bar 3; the first end of the first connecting horizontal bar 3 and the first end of the first connecting vertical bar 6 are both connected to the fixed part of the damper 2, the first end of the second connecting rod is connected to the movable part of the damper 2, and the second end of the first connecting horizontal bar 3, the second end of the first connecting vertical bar 6, and the second end of the second connecting rod are each used to connect to the corresponding flexible cable of the corresponding photovoltaic support.

[0023] This invention provides a photovoltaic support vibration damping device. When the corresponding flexible cable connected to it vibrates under load, the mass block 1 moves up and down with the vibration of the first connecting crossbar 3, thereby driving the second connecting rod and the first connecting vertical rod 6 to move, thus transferring the vibration energy to the damper 2. The damper 2 absorbs part of the vibration energy, which can effectively reduce the deformation of the photovoltaic support structure caused by wind load. In the implementation process, the number of mass blocks can be changed to adapt to the vibration frequency of different areas of the photovoltaic support flexible cable structure system. This photovoltaic support vibration damping device has a simple structural design, a simple and reliable connection method, and is easy to manufacture, install and maintain.

[0024] As one possible implementation method, see Figures 1 to 4As shown, the damper 2 may include an outer cylinder 8 and an inner cylinder 9; the inner cylinder 9 is coaxially sleeved inside the outer cylinder 8, and the outer cylinder 8 contains a damping medium; the fixed part may include the outer cylinder 8; the movable part may include the inner cylinder 9; the first end of the first connecting crossbar 3 and the first end of the first connecting vertical bar 6 are both connected to the outer cylinder 8. With this design, when vibration occurs under load, the mass block 1 will move up and down with the vibration of the first connecting crossbar 3, thereby driving the second connecting rod and the first connecting vertical bar 6 to move, thus transferring the vibration energy to the damper 2, and absorbing part of the vibration energy through the outer cylinder 8, the inner cylinder 9 and the damping medium.

[0025] As one possible implementation method, see Figures 1 to 4 As shown, the damper 2 may also include a spring 10; one end of the spring 10 is fixedly connected to the outer cylinder 8, and the second end of the spring 10 is fixedly connected to the inner cylinder 9. With this design, if the vibration energy generated when the load causes vibration is transmitted to the damper 2, part of the vibration energy can be absorbed by the elastic deformation of the spring 10.

[0026] As one possible implementation method, see Figures 1 to 4 As shown, the second connecting rod may include a second connecting crossbar 4; the first end of the second connecting crossbar 4 is connected to the inner cylinder 9, and the second end of the second connecting crossbar 4 is used to connect to a corresponding flexible cable. With this design, the up-and-down movement of the mass block 1 will drive the second connecting crossbar 4 and the first connecting vertical bar 6 to move, thereby transferring the vibration energy to the damper 2, so that the damper 2 can absorb part of the vibration energy through its own structure (including the outer cylinder 8, the inner cylinder 9, the damping medium, and the spring 10).

[0027] As one possible implementation method, see Figures 1 to 4 As shown, the second connecting rod may further include a second connecting vertical rod 5; the first end of the second connecting vertical rod 5 is connected to the inner cylinder 9, and the second end of the second connecting vertical rod 5 is connected to the first end of the second connecting horizontal rod 4. With this design, the up-and-down movement of the mass block 1 will drive the second connecting vertical rod 5, the second connecting horizontal rod 4, and the first connecting vertical rod 6 to move, thereby transferring vibration energy to the damper 2 so that the damper 2 can absorb some of the vibration energy.

[0028] As one possible implementation method, see Figures 1 to 4As shown, the second end of the first connecting crossbar 3 is used to connect with the corresponding flexible cable of one of the photovoltaic supports, and the second ends of the first connecting vertical bar 6 and the second connecting crossbar 4 are each used to connect with the corresponding flexible cable of the other photovoltaic support. With this design, when the corresponding flexible cables of the different connected photovoltaic supports vibrate under load, the up-and-down movement of the mass block 1 will drive the movement of the second connecting vertical bar 5, the second connecting crossbar 4, and the first connecting vertical bar 6, thereby transferring the vibration energy to the damper 2. The damper 2 absorbs some of the vibration energy, effectively reducing the structural deformation of the different photovoltaic supports caused by wind load.

[0029] As one possible implementation method, see Figures 1 to 4 As shown, clamps 7 are provided at the second end of the first connecting horizontal bar 3, the second end of the first connecting vertical bar 6, and the second end of the second connecting horizontal bar 4; each clamp 7 is used to connect to the corresponding flexible cable. With this design, the corresponding connecting bar can be easily connected to the corresponding flexible cable through the clamps 7 at the ends of the corresponding connecting bars, thereby improving the ease of installation of the photovoltaic support vibration damping device.

[0030] As one possible implementation method, see Figures 1 to 4 As shown, the second end of the first connecting crossbar 3, which is used to connect to the first position of its corresponding flexible cable, and the second end of the first connecting vertical bar 6, which is used to connect to the second position of its corresponding flexible cable, are both higher than the third position of the second end of the second connecting crossbar 4, which is used to connect to its corresponding flexible cable.

The end of the first connecting vertical bar 6 is fixedly provided with a clamp 7 (for connecting with the corresponding flexible cable). When the corresponding flexible cable connected to it vibrates under load, the mass block 1 will move up and down with the vibration, which will drive the second connecting vertical rod 5, the second connecting horizontal rod 4, and the first connecting vertical rod 6 to move, thereby transferring the vibration energy to the damper 2, and absorbing part of the vibration energy through the elastic deformation of the spring 10; by adjusting the number of mass blocks 1, the natural frequency of the photovoltaic bracket vibration damping device can be adjusted, so that the photovoltaic bracket vibration damping device can adapt to the natural frequency of different areas.

[0033] This invention also provides an installation method for a photovoltaic bracket vibration damping device, see [link to relevant documentation].

[0035] Step S506: Connect the second end of the first connecting horizontal bar 3, the second end of the first connecting vertical bar 6, and the second end of the second connecting bar to the corresponding flexible cable of the corresponding photovoltaic bracket.

[0036] Using the above installation method, the photovoltaic support vibration damping device can effectively reduce the deformation of the photovoltaic support structure caused by wind load. During implementation, the vibration frequency of different areas of the photovoltaic support flexible cable structure system can be adapted by changing the number of mass blocks. The photovoltaic support vibration damping device has a simple structural design, simple and reliable connection method, and is easy to manufacture, install and maintain.

[0037] As one possible implementation, step S506 (connecting the second end of the first connecting crossbar 3, the second end of the first connecting vertical bar 6, and the second end of the second connecting rod to the corresponding flexible cable of the corresponding photovoltaic bracket) may include: connecting the second end of the first connecting crossbar 3 to the corresponding flexible cable of one of the photovoltaic brackets; and connecting the second end of the first connecting vertical bar 6 and the second end of the second connecting rod to the corresponding flexible cable of another photovoltaic bracket.

[0042] Step S3: For each photovoltaic support vibration damping device, the first connecting crossbar 3 is welded to the outer cylinder 8 of the damper 2, and the inner cylinder 9 of the damper 2 is welded to the second connecting crossbar 4.

[0043] Step S4: For each photovoltaic support vibration damping device, connect the clamp 7 at the end of the first connecting crossbar 3 to the high point of a cable (corresponding to the first position mentioned above).

[0044] Step S5: For each photovoltaic support vibration damping device, connect the clamp 7 at the end of the first connecting vertical rod 6 to the high point of another cable (corresponding to the second position mentioned above), and connect the clamp 7 at the end of the second connecting horizontal rod 4 to the low point of the same cable (corresponding to the third position mentioned above).

[0045] This invention connects the damper to the mass block via a portion of the connecting rods, and connects the photovoltaic support vibration damping device to the corresponding flexible cable via another portion of the connecting rods and clamps, enabling the photovoltaic support vibration damping device and the flexible cable to work together to absorb part of the vibration energy.
