Description

Technical Field

[0001] This utility model relates to the field of reducing suspension cable sway, and in particular to a device for reducing the sway of flexible photovoltaic suspension cables. Background Technology

[0002] With the continuous development of clean energy, photovoltaic power generation has been widely used as a sustainable and environmentally friendly way to obtain energy. Among the various layout forms of photovoltaic systems, flexible photovoltaic suspension structures have gradually emerged due to their strong adaptability and flexible installation in different terrains and spatial environments. However, flexible photovoltaic suspension structures face a severe challenge in practical applications, namely, they are prone to swaying in windy weather. This swaying not only affects the normal power generation efficiency of photovoltaic modules, making it difficult for photovoltaic panels to receive sunlight stably, but also causes fatigue damage to the suspension cable itself and various connecting structures connected to it in the long term, shortening the service life of the entire photovoltaic system. In order to solve this key problem, a device to reduce the swaying of flexible photovoltaic suspension cables has emerged. It aims to effectively suppress the swaying of suspension cables in windy weather and improve the reliability and stability of flexible photovoltaic systems through innovative design and technology applications.

[0003] In the past, in order to deal with the swaying problem of flexible photovoltaic suspension cables, some existing technologies have adopted relatively traditional wind protection measures. A common approach is to simply increase the diameter of the suspension cable or select higher strength suspension cable materials, attempting to reduce swaying by improving the wind resistance of the suspension cable itself. The principle is that a thicker suspension cable or a stronger material can enhance the suspension cable's ability to resist deformation under wind force to a certain extent, making it less likely for the suspension cable to be easily blown away and cause large swings when strong winds come.

[0004] However, simply increasing the strength of the suspension cable itself is insufficient to fundamentally and effectively solve the problem of swaying of flexible photovoltaic suspension cables in windy weather. For example, even if the strength of the suspension cable itself is improved, it will still sway significantly under the complex forces of strong winds due to the lack of sufficient targeted constraints. This will still significantly affect the power generation efficiency of photovoltaic modules and make it impossible to guarantee stable and continuous power output in windy weather. Therefore, a device to reduce the swaying of flexible photovoltaic suspension cables is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a device to reduce the swaying of flexible photovoltaic suspension cables, aiming to improve the problem that traditional equipment in the prior art lacks an effective and targeted constraint mechanism and cannot fundamentally and comprehensively suppress the swaying of the suspension cables.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for reducing the swaying of a flexible photovoltaic suspension cable includes a support rod, a steel cable fixedly connected to the inner side of the support rod, a fixing rod fixedly connected to the surface of the steel cable, and a fixing component provided on the outer wall of the steel cable. The fixing component is used to reduce the violent swaying of the photovoltaic panel under the action of external force.

[0008] The fixing component includes a fixing ring slidably connected to the outer wall of the steel cable, a fixing shaft fixedly connected inside the fixing ring, a screw threadedly connected inside the fixing shaft, an elastic washer fixedly connected to the bottom of the screw, a conical block fixedly connected to the bottom of the elastic washer, a fixing ball slidably connected to the outer wall of the conical block, a connecting plate slidably connected to the outer wall of the fixing shaft, a slot provided inside the connecting plate, the fixing ball fitting into the slot, and a buffer component provided at the bottom of the fixing rod for effectively absorbing the pressure generated by the shaking of the photovoltaic panel.

[0009] As a further description of the above technical solution:

[0010] The buffer assembly includes a transmission column and a transmission disk. The top end of the transmission column is fixedly connected to the bottom of the fixed rod, and the upper surface of the transmission disk is fixedly connected to the bottom end of the transmission column.

[0011] As a further description of the above technical solution:

[0012] A U-shaped block is fixedly connected to the bottom of the transmission disc, and a connecting disc is fixedly connected to the bottom of the U-shaped block;

[0013] As a further description of the above technical solution:

[0014] Both sides of the connecting plate are rotatably connected to connecting columns, and sliding columns are slidably connected inside the connecting columns;

[0015] As a further description of the above technical solution:

[0016] A telescopic shaft is fixedly connected to the bottom of the connecting plate, and a spring is provided at the bottom of the connecting plate;

[0017] As a further description of the above technical solution:

[0018] One end of the spring is fixedly connected to the lower surface of the connecting plate, and the other end of the spring is fixedly connected to a load-bearing plate;

[0019] As a further description of the above technical solution:

[0020] One side of the sliding column is fixedly connected to the upper surface of the load-bearing plate, and the bottom of the load-bearing plate is fixedly connected to a fixed foot.

[0021] This utility model has the following beneficial effects:

[0022] In this invention, the screw is rotated inside the fixed shaft, which further drives the elastic pad to deform elastically. During the movement of the elastic pad, the conical block is further driven to move. The conical block forces the fixed ball to roll on its surface, thereby effectively fixing the fixed rod inside the fixed ring. This solves the problem that traditional equipment cannot prevent the fixed rod from shaking violently in windy weather, and improves the service life and safety of the equipment.

[0023] In this invention, the pressure generated when the fixed rod shakes is transmitted to the transmission disc via the transmission column, which in turn drives the connecting disc. The movement of the connecting disc further drives the spring and the telescopic shaft, thereby effectively absorbing the pressure generated when the fixed rod shakes. This solves the problem of instability caused by the inability of traditional equipment to effectively absorb pressure, and improves the stability and service life of the equipment.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a device for reducing the swaying of a flexible photovoltaic suspension cable, comprising a support rod 1, a steel cable 2 fixedly connected to the inner side of the support rod 1 for suspending a photovoltaic panel, a fixing rod 3 fixedly connected to the surface of the steel cable 2, the fixed connection between the fixing rod 3 and the photovoltaic panel ensuring the overall structural stability of the device, and a fixing component provided on the outer wall of the steel cable 2 for reducing the violent swaying of the photovoltaic panel under external force.

[0032] The fixing component includes a fixing ring 4, which is slidably connected to the outer wall of the steel cable 2. A fixing shaft 5 is fixedly connected inside the fixing ring 4, and a screw 6 is threadedly connected inside the fixing shaft 5. An elastic washer 7 is fixedly connected to the bottom of the screw 6. The fixing shaft 5 serves to support and transmit force. The rotation of the screw 6 not only adjusts the tightness of the fixing component but also further pushes the downstream elastic washer 7. A conical block 8 is fixedly connected to the bottom of the elastic washer 7, and a fixing ball 9 is slidably connected to the outer wall of the conical block 8. The fixing ball 9, through sliding contact with the conical block 8, can... Adjustments are made according to the direction and magnitude of the external force to ensure the flexibility and responsiveness of the device. A connecting plate 10 is slidably connected to the outer wall of the fixed shaft 5. A slot 11 is opened inside the connecting plate 10. The fixed ball 9 fits into the slot 11. The slot 11 opened inside the connecting plate 10 can precisely fit into the fixed ball 9. When external pressure is applied, the fixed ball 9 will slide into the slot 11, producing a stable locking effect, thereby effectively preventing the steel cable 2 from shifting and ensuring the fixation of the photovoltaic panel. A buffer component is provided at the bottom of the fixed rod 3. The buffer component is used to effectively absorb the pressure generated by the shaking of the photovoltaic panel.

[0033] Specifically, in windy weather, wind speeds often reach high levels, exerting a strong impact on the flexible photovoltaic suspension cable, causing it to sway violently. The operator first places the steel cable 2 inside the fixing ring 4 to ensure its stable position. Next, the operator rotates the screw 6 within the fixed shaft 5. The rotation of the screw 6 drives the threaded portion on the fixed shaft 5 to move, further pushing the elastic washer 7 to undergo elastic deformation. The deformation of the elastic washer 7 not only acts as a buffer but also transmits motion through its elastic deformation, causing the conical block 8 to move synchronously. During the movement of the conical block 8, its outer wall comes into contact with the fixed ball 9. Guided by the conical block 8, the fixed ball 9 rolls along the outer wall of the conical surface. When the fixed ball 9 moves, it enters the slot 11 and precisely matches the shape of the slot 11, thereby realizing the connection between the steel cable 2 and the fixed ring 4. In a windy environment, the rotation of the screw 6 not only causes the elastic washer 7 to deform and drive the conical block 8 to move synchronously, but also effectively increases the stability of the steel cable 2 through the cooperation of the fixed ball 9 and the slot 11, reduces the swaying caused by the wind, and ensures that the fixed rod 3 always stays in the ideal position.

[0034] Reference Figure 4 The buffer assembly includes a transmission column 12 and a transmission disc 13. The top of the transmission column 12 is fixedly connected to the bottom of the fixed rod 3. The main function of the transmission column 12 is to transmit power or motion from the fixed rod 3 to the downstream assembly. To ensure transmission stability, the upper surface of the transmission disc 13 is fixedly connected to the bottom of the transmission column 12. A U-shaped block 14 is fixedly connected to the bottom of the transmission disc 13 to further transmit force and absorb the force. A connecting disc 15 is fixedly connected to the bottom of the U-shaped block 14. The function of the connecting disc 15 is to connect the transmission disc 13 to the downstream motion assembly through the U-shaped block 14. Connecting columns 16 are rotatably connected to both sides of the connecting disc 15. A sliding column 17 is slidably connected inside the connecting column 16, which can move freely within a certain stroke range. The structural design of the sliding column 17 ensures that it can withstand a large axial force during operation without generating excessive friction.

[0035] Specifically, in windy weather, especially when the wind speed is high and the wind direction is changeable, the flexible photovoltaic suspension cable will be subjected to strong and complex wind forces, resulting in relatively violent swaying, large-scale left-right swinging, up-down undulation, and torsion. First, the pressure applied by the outside is effectively transmitted to the transmission disc 13 through the transmission column 12. The function of the transmission column 12 is to guide and concentrate the external mechanical force so as to further transmit it to the next link. As a key component, the transmission disc 13 converts the pressure into linear force through its connection with the transmission column 12, and further distributes the pressure to the connecting disc 15 through its own structure. After receiving the transmitted force, the connecting disc 15 begins to undergo elastic deformation.

[0036] Reference Figure 4 A telescopic shaft 20 is fixedly connected to the bottom of the connecting plate 15. The telescopic shaft 20 has an adjustable length and can automatically adjust according to the pressure, thereby effectively absorbing some of the pressure. A spring 19 is set at the bottom of the connecting plate 15. The spring 19 is located below the connecting plate 15 and forms an effective synergy with the bottom of the telescopic shaft 20. The elasticity of the spring 19 plays a supporting role and can achieve a certain degree of buffering and recovery under the action of external force, enhancing the stability and elasticity of the overall structure. One end of the spring 19 is fixedly connected to the lower surface of the connecting plate 15, and the other end of the spring 19 is fixedly connected to the load-bearing plate 18. One side of the sliding column 17 is fixedly connected to the upper surface of the load-bearing plate 18. Fixed feet 21 are fixedly connected to the bottom of the load-bearing plate 18. These fixed feet 21 not only make the whole system have strong stability, but also maintain balance in different working states of the load-bearing plate 18.

[0037] Specifically, because the connecting plate 15 is made of elastic material, it can effectively absorb and buffer external pressure, reducing the impact force directly acting on the photovoltaic panel. At the same time, the movement of the connecting plate 15 synchronously drives the connecting column 16 to slide along the sliding column 17. The sliding column 17 provides a guide trajectory to ensure the smooth movement of the connecting column 16 and avoid structural damage caused by poor movement. The sliding of the connecting column 16 inside the sliding column 17 plays an important role. It can effectively and evenly distribute the pressure applied to the connecting plate 15, ensuring that the entire system can smoothly absorb and distribute external forces, thereby reducing the impact of external impacts on the photovoltaic panel. In particular, under strong winds or other environmental factors, photovoltaic panels are prone to violent shaking. The coordinated movement of the connecting plate 15 and the connecting column 16 can effectively reduce this shaking and prevent damage to the photovoltaic panels due to uneven force. In addition, the cooperation between the spring 19 and the entire transmission system also plays an important role. The spring 19 not only provides restoring force during the elastic movement of the connecting plate 15, but also enhances the buffering capacity of the entire system through its own elastic characteristics. When the external force disappears, the spring 19 will restore the system to its original state, ensuring that the device can maintain stable performance and structural integrity during long-term use.

[0038] Working principle: When using this device, the operator places the steel cable 2 inside the fixed ring 4 and rotates the screw 6, causing it to rotate inside the fixed shaft 5. During this rotation, the elastic pad 7 will further deform elastically, thereby causing the conical block 8 to move synchronously. During the movement of the conical block 8, the fixed ball 9 will be forced to roll on the outer wall of the conical block 8, thus cooperating with the slot 11 to achieve fixation and unlocking, thereby firmly fixing the steel cable 2 inside the fixed ring 4. In windy weather, this effectively reduces the swaying of the steel cable 2. At the same time, during the swaying of the photovoltaic panel, the pressure is transmitted to the transmission disc 13 through the transmission column 12. The transmission disc 13 further transmits the force, thereby causing the connecting disc 15 and the spring 19 to move elastically. While the connecting disc 15 moves, it further causes the connecting column 16 to slide inside the sliding column 17, thereby effectively and evenly absorbing the pressure and preventing the photovoltaic panel from being damaged by violent swaying under external force.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
