[0002] Compared with traditional photovoltaic brackets, flexible photovoltaic cables have the advantages of convenient installation and low cost. Since flexible photovoltaic cables do not require deep foundation digging or large-scale civil engineering, they can be quickly installed on the basis of limited load-bearing capacity, which significantly reduces the manpower and material investment in the installation process and reduces the installation cost. In addition, flexible photovoltaic cables are light in weight and simple in structure. They can be quickly installed on the basis of limited load-bearing capacity such as roofs and water surfaces, greatly reducing the installation cost.

[0003] Flexible photovoltaic cables are made of flexible materials that can twist, bend, and deform to cope with erosion from natural environmental factors such as wind and rain. They also have high strength and toughness, which improves the stability of the photovoltaic system and extends the service life of photovoltaic modules. When photovoltaic modules are impacted by external forces, flexible photovoltaic cables can buffer and absorb, reduce the stress of photovoltaic modules, and avoid damage. In addition, the design of flexible photovoltaic cables can be adjusted according to the angle of light and seasonal changes, ensuring that the angle between photovoltaic modules and the sun is always optimal, thereby improving the power generation efficiency of the photovoltaic system.

[0004] Under the influence of natural factors such as wind and rain erosion and sun exposure, flexible photovoltaic cables can twist, bend and deform, and the bracket itself has high strength and high toughness. Therefore, compared with traditional brackets, flexible photovoltaic cables can better withstand complex natural environments and extend the service life of photovoltaic modules.

[0005] Therefore, the measurement of the force of flexible photovoltaic cables is of great significance. By measuring the force of flexible photovoltaic cables, its stress state under various environmental conditions can be evaluated, potential safety hazards can be discovered in time, and corresponding measures can be taken to repair or reinforce it to ensure the safe operation of the photovoltaic system. Regular force measurement of photovoltaic cables can timely discover and solve potential problems such as material aging and loose connections, thereby extending the service life of the photovoltaic system.

Since the mounting member 1 and the fixing member 2 are detachably connected and fastened by the connection component, the installation process is simple and quick. The optical fiber sensor 3 is sleeved on the photovoltaic cable and can be applied to photovoltaic cables of different types and specifications, and has strong versatility. The optical fiber sensor 3 can monitor the verticality of the photovoltaic cable in real time, has high detection accuracy, and can timely detect the distortion, deformation, etc. of the photovoltaic cable. Through the electrical connection with the detection component, the optical fiber sensor 3 can transmit data in real time, so that the verticality change of the photovoltaic cable can be monitored in time, thereby improving safety and reliability. By monitoring the verticality of the photovoltaic cable, it is possible to detect excessive cable tension or abnormal conditions in a timely manner, which helps to avoid safety accidents in the photovoltaic system. The device adopts a detachable connection design, which is convenient for daily maintenance and extends the service life of the device. Compared with traditional cable tension detection devices, this device is less expensive, which not only improves the safety and reliability of the photovoltaic system, but also reduces maintenance costs.

[0025] In this embodiment, a mounting groove 11 is provided on the outside of the cavity, and the optical fiber sensor 3 is mounted in the mounting groove 11. The mounting groove 11 provides a fixed position so that the optical fiber sensor 3 can be firmly mounted on the outside of the cavity. This ensures that the performance and accuracy of the optical fiber sensor 3 will not be affected by movement or loosening during use. The mounting groove 11 can effectively protect the optical fiber sensor 3 from the influence of the external environment, such as wind and rain erosion, dust, particles, etc. This helps to extend the service life of the optical fiber sensor 3 and reduce maintenance and replacement costs. The mounting groove 11 provides an accurate position and direction so that the optical fiber sensor 3 can be correctly installed on the outside of the cavity. This helps to ensure that the position and direction of the optical fiber sensor 3 are aligned with the photovoltaic cable, and improves the accuracy and reliability of the detection. The optical fiber sensor 3 is mounted in the mounting groove 11, making the installation process simpler and faster. At the same time, if the optical fiber sensor 3 needs to be replaced or maintained, it can also be easily operated, reducing the time and cost of maintenance work. The mounting groove 11 is reasonably designed, which not only ensures the stability and accuracy of the optical fiber sensor 3, but also makes the overall appearance of the device more beautiful, increasing the practicality and ornamental value of the device.

[0026] In this embodiment, the mounting groove 11 extends along the length direction of the cavity. Since the mounting groove 11 extends along the length direction of the cavity, the surface of the photovoltaic cable can be covered in a larger range. This ensures that the optical fiber sensor 3 can fully contact different parts of the photovoltaic cable, improving the comprehensiveness and accuracy of the detection. The extended design of the mounting groove 11 enables the optical fiber sensor 3 to be evenly stressed, avoiding excessive stress concentration at a specific position. This helps to protect the optical fiber sensor 3 from being easily damaged and prolong its service life. The mounting groove 11 extends along the length direction of the cavity, making the device more flexible and adaptable. Regardless of how the length of the photovoltaic cable changes, the mounting groove 11 can meet the needs and ensure that the optical fiber sensor 3 can be effectively mounted and operated. Since the mounting groove 11 extends along the entire length of the cavity, there is no need to consider a specific position when installing the optical fiber sensor 3, which simplifies the installation process. This reduces the complexity and difficulty of installation and improves the convenience of operation. The mounting groove 11 extends along the length direction of the cavity, making the optical fiber sensor 3 more firmly and stably fixed on the cavity. This helps to keep the position and direction of the sensor unchanged and improve the stability and accuracy of the detection.

[0027] In this embodiment, the mounting groove 11 is provided on any one of the mounting member 1 and the fixing member 2. The position of the mounting groove 11 is not fixed, and it can be set on the mounting member 1 or the fixing member 2 according to the specific situation. This design enhances the flexibility of the device, and the best installation position can be selected according to actual needs and installation environment. Both the mounting member 1 and the fixing member 2 can be used as the position of the mounting groove 11, so it has a wider applicability. It is not limited by specific components and can be applied to photovoltaic cables of different types and specifications, which improves the versatility of the device. Installing the mounting groove 11 on any component makes the maintenance of the device more convenient. If the mounting groove 11 needs to be replaced or repaired, a more convenient component can be selected according to the actual situation to operate, saving maintenance time and cost. The mounting groove 11 can be set on the mounting member 1 or the fixing member 2 as needed, avoiding unnecessary waste of materials. This flexible design can make the best use of raw materials, reduce production costs and waste of resources. Limited by the fixed position, the design is more concise and clear. The position of the mounting groove 11 can be freely set according to the overall layout and functional requirements of the device, making the design more flexible and efficient.

[0028] In this embodiment, the cavity is tubular, and the cavity is clamped in the middle section of the photovoltaic cable. As a supporting structure of the flexible photovoltaic cable, the cavity is tubular to distribute the force more evenly. Installing the photovoltaic cable in the middle section can make the cable force more balanced, reduce the concentration of local stress, and help improve the stability and safety of the device. As a protective device, the cavity is clamped in the middle section of the photovoltaic cable, which can effectively protect the photovoltaic cable from the influence and damage of the external environment. The middle section position is more stable than the two ends, which can reduce the shaking and vibration of the photovoltaic cable during the installation process, thereby extending the service life of the photovoltaic cable. Installing the cavity in the middle section of the photovoltaic cable makes installation easier. Compared with the device installed at both ends, the middle section position is easier to control and adjust, which reduces the complexity of the installation process and improves the construction efficiency. The tubular cavity design is more in line with the structural characteristics of the photovoltaic cable and can better cooperate with the bending and deformation of the photovoltaic cable. This design optimizes the structural layout, improves the stability and reliability of the device, and reduces the maintenance cost of the photovoltaic system. By installing the cavity in the middle section of the photovoltaic cable, the stress on the photovoltaic system under severe weather conditions can be effectively reduced, the safety and reliability of the system can be improved, and the probability of accidents can be reduced.

The design of the plurality of tenons 4 and mortises 5 makes the connection more flexible and can be combined and adjusted according to actual conditions. This design allows the tenons 4 and mortises 5 to be installed at different positions to accommodate photovoltaic cables of different shapes and sizes, thereby improving the versatility and applicability of the device. The mutual matching of the tenons 4 and mortises 5 ensures the stability and firmness of the connection. Through the cooperation of the tenons and mortises, the connection between the mounting member 1 and the fixing member 2 can be effectively fixed to prevent it from loosening or falling off, thereby ensuring the safety and stability of the entire device. The design of the tenons 4 and mortises 5 makes the installation process simpler and faster. The installer only needs to insert the tenons 4 into the mortises 5 at the corresponding positions to complete the connection, without the need for complex tools or professional skills, thereby improving the efficiency and convenience of installation. The design of the tenon 4 and the mortise 5 makes the connector detachable, which is convenient for daily maintenance and replacement. If the device needs to be adjusted or parts need to be replaced, only the corresponding tenon 4 and mortise 5 need to be removed and the corresponding operation needs to be performed without reinstalling the entire device, thus saving maintenance costs and time. Due to the simple design and easy processing of the tenon 4 and the mortise 5, the manufacturing cost is relatively low. At the same time, its detachability and flexibility also reduce the maintenance cost and the cost of replacing parts, making the total cost of the overall device more economical.

[0030] In this embodiment, the connection assembly also includes a binding belt 6, which is fastened to both ends of the cavity. The use of the binding belt 6 can increase the stability of the device. By fastening the binding belt 6 to both ends of the cavity, the entire device can be effectively fixed and reinforced to prevent it from shaking or shifting under the external environment or external force, thereby improving the stability and safety of the device. The binding belt 6 can play a role in protecting the device. It can fix the cavity and fit it tightly on the surface of the photovoltaic cable to prevent the cavity from being damaged by external impact or extrusion. This can extend the service life of the device and reduce the cost of maintenance and repair. The design of the binding belt 6 makes the installation process simpler and faster. The installer only needs to fix the binding belt 6 on both ends of the cavity to complete the fixing of the device, without complex tools or professional skills, thereby improving the installation efficiency and convenience. The binding belt 6 can make the appearance of the entire device neater and more beautiful. It can firmly fix the cavity on the surface of the photovoltaic cable, avoid loose or protruding parts, make the device look more concise and delicate, and enhance the visual effect. The use of the binding belt 6 can adapt to photovoltaic cables of different shapes and sizes. Since the binding belt 6 has certain elasticity and adjustability, it can be adjusted according to the actual situation of the photovoltaic cable to ensure a close connection between the device and the photovoltaic cable, thereby improving the versatility and applicability of the device.
