[0026] 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.

[0027] Please see Figure 1-6 This utility model provides a technical solution: a solar-powered cable tension monitoring device, comprising:

[0028] Housing 1, and tension sensor body 2 disposed on the top of housing 1;

[0029] The top of the tension sensor body 2 is equipped with a fastening mechanism 3 for cable placement;

[0030] Rectangular slots 4 are provided on both sides of the outer casing 1. Solar charging panels 5 are installed inside the two rectangular slots 4. A rotating mechanism 6 for adjusting the angle of the solar charging panels 5 is installed inside the rectangular slots 4.

[0031] Specifically, when monitoring cable tension, the cable is fixed at three points: the end clamps 11 and the middle clamp 12. Then, the middle clamp 12 fastening bolt 14 is tightened to ensure tight contact between the cable and the end clamps 11 and the middle clamp 12, creating a certain deformation in the cable. Different cable tensions result in different deformations, and the sensor calculates the cable tension based on this deformation. The tension sensor is connected to the AD sampling chip on the circuit board 18 via a cable to achieve real-time tension acquisition. The MCU chip in the core circuit reads and wirelessly transmits the data. When using a 4G network, the monitoring data is transmitted through the 4G antenna 15 of the data transmission unit; when using a LoRa network, the monitoring data is transmitted through the LoRa antenna 16 of the data transmission unit, ensuring compatibility with both wireless communication methods.

[0032] The rotating mechanism 6 includes two plates 61 fixedly installed on one side of the solar charging panel 5. A rod 62 is fixedly installed on one side of the two plates 61. Two seats 63 are rotatably installed on the surface of the rod 62. A mounting seat 64 is fixedly installed on one side of the two seats 63. A limiting component 60 for providing damping force to the rotation of the rod 62 is provided inside the mounting seat 64.

[0033] In this embodiment, the combination of plate 61, rod 62 and base 63 achieves stable rotational support for the solar charging panel 5. The structure is compact, easy to install and maintain. The rotational connection between rod 62 and base 63 allows the solar charging panel 5 to be adjusted at multiple angles to adapt to different lighting conditions and improve solar energy absorption efficiency. The mounting base 64 is fixed in the rectangular groove 4 to ensure the stability of the overall structure and prevent loosening or displacement. The groove 601 is larger than the solar charging panel 5, which enables the rotational adjustment of the solar charging panel 5.

[0034] The limiting component 60 includes a groove 601 formed in the mounting base 64. A spring 602 is attached to one side of the inner wall of the groove 601 via a retainer. A floating toothed plate 603 is attached to the other end of the spring 602 via a retainer. The surface of the floating toothed plate 603 is slidably installed with the inside of the groove 601. A gear 604 is fixedly installed on the surface of the rod 62. The gear 604 meshes with the teeth on the surface of the floating toothed plate 603.

[0035] It should be noted that rotating the solar charging panel 5 can drive the rod 62 to rotate, and the gear 604 on the surface of the rod 62 rotates. Since the gear 604 meshes with the floating toothed plate 603, and the spring 602 cooperates with the floating toothed plate 603, it provides adjustable damping force, so that the solar charging panel 5 can maintain its position stably after the angle is adjusted, avoiding displacement due to wind or vibration. The meshing structure of the gear 604 and the floating toothed plate 603 ensures a clear sense of gear position when rotating, which makes it convenient for users to adjust the angle accurately. The meshing of the floating toothed plate 603 and the gear 604 prevents the rod 62 from rotating freely, thus improving stability.

[0036] A guide rod 7 is fixedly installed on one side of the floating toothed plate 603. One end of the guide rod 7 passes through one side of the mounting base 64 and extends outward. The surface of the guide rod 7 is movably connected to the inside of the spring 602.

[0037] The guide rod 7 passes through the mounting base 64, restricting the movement direction of the floating toothed plate 603, preventing it from deviating or jamming, and ensuring the uniform application of damping force.

[0038] It also includes an extension mechanism 8 for stretching the solar charging panel 5. The extension mechanism 8 includes a connecting frame 81 that is fixedly installed at the bottom of the mounting base 64 and is concave. A support plate 82 is fixedly installed on the inner wall of the connecting frame 81. A support frame 83 is provided on the surface of the support plate 82. One side of the support frame 83 is fixedly installed on the inner wall of the groove 601. An adhesive layer seat 84 is fixedly installed on the surface of the support plate 82. The surface of the adhesive layer seat 84 is in close contact with the inner wall of the support frame 83.

[0039] Furthermore, the connecting frame 81 and the support plate 82 provide additional support to prevent the solar charging panel 5 from being deformed or damaged by external forces (such as strong winds). The adhesive layer seat 84 fits tightly with the support frame 83 to reduce vibration and friction and improve the service life of the solar charging panel 5.

[0040] Both sides of the solar charging panel 5 are provided with pull tabs 9, and one side of the support frame 83 is provided with a ventilation groove 10.

[0041] Among them, the ventilation groove 10 of the support frame 83 is used for the circulation of gas inside the support frame 83 to prevent the adhesive layer seat 84 from being unable to move inside the support frame 83, while the pull plate 9 is designed to allow users to manually adjust the angle of the solar charging panel 5 without additional tools.

[0042] The tension sensor body 2 has side bayonets 11 for fixing the two ends of the cable on both sides of the top. The tension sensor body 2 has a middle bayonet 12 for fixing the middle of the cable on the top. Two threaded rods 13 are slidably installed inside the middle bayonet 12. Fastening bolts 14 are provided on the surface of the two threaded rods 13. The two fastening bolts 14 are located on the top of the middle bayonet 12. A data transmission unit 4G antenna 15 and a data transmission unit LORA antenna 16 are provided on one side of the outer shell 1.

[0043] It is worth noting that when monitoring cable tension, after the cable is fixed at three points—the end clamps 11 and the middle clamp 12—the middle clamp 12 is tightened with the fastening bolt 14, ensuring tight contact between the cable and the end clamps 11 and the middle clamp 12. This creates a certain deformation in the cable. Different cable tensions result in different deformations, and the sensor calculates the cable tension based on this deformation. The tension sensor is connected to the AD sampling chip on the circuit board 18 via a cable, enabling real-time tension acquisition. The MCU chip in the core circuit reads and wirelessly transmits the data. When using a 4G network, the monitoring data is transmitted through the 4G antenna 15 of the data transmission unit; when using a LoRa network, the monitoring data is transmitted through the LoRa antenna 16 of the data transmission unit, thus ensuring compatibility with both wireless communication methods.

[0044] The interior of the housing 1 contains a lithium battery 17, a circuit board 18, and a sensor connecting bolt 19. The lithium battery 17 is electrically connected to two solar charging panels 5. A charging terminal electrically connected to the lithium battery 17 is installed on one side of the housing 1.

[0045] Specifically, the outer casing 1 is an all-metal casing with strong anti-electromagnetic interference and anti-aging capabilities. All components are tightly connected, supporting 4G and LoRa wireless communication functions, possessing multiple networking capabilities, adapting to various application scenarios, and powered by solar energy, enabling the monitoring device to operate continuously and realize online real-time monitoring of cables, providing a data foundation for intelligent operation and maintenance of railway contact networks and power grid cables. The tension monitoring device has a higher degree of integration, is easy to install, and has strong maintainability, which can greatly reduce the hardware and labor costs of engineering applications and operation and maintenance. The cable between the lithium batteries 17 of the solar charging panel 5 is relatively long, which can meet the rotation adjustment of the solar charging panel 5.

[0046] Rotating the solar charging panel 5 causes the rod 62 to rotate, which in turn rotates the gear 604 on the surface of the rod 62. Since the gear 604 meshes with the floating gear plate 603, and the spring 602 cooperates with the floating gear plate 603, it provides adjustable damping force, ensuring that the solar charging panel 5 can maintain its position stably after the angle is adjusted, preventing displacement due to wind or vibration. The meshing structure of the gear 604 and the floating gear plate 603 ensures a clear sense of rotation, facilitating precise angle adjustment by the user. The meshing of the floating gear plate 603 and the gear 604... To prevent the rod 62 from rotating freely and improve stability, when monitoring cable tension, the cable is fixed at three points: the end clamps 11 and the middle clamp 12. Then, the middle clamp 12 fastening bolt 14 is tightened to ensure tight contact between the cable and the end clamps 11 and the middle clamp 12, creating a certain deformation in the cable. Different cable tensions result in different deformations, and the sensor calculates the cable tension based on this deformation. The tension sensor is connected to the AD sampling chip on the circuit board 18 via a cable to achieve real-time tension acquisition. The MCU chip in the core circuit enables data reading and wireless transmission. When using a 4G network, the monitoring data is transmitted through the 4G antenna 15 of the data transmission unit; when using a LoRa network, the monitoring data is transmitted through the LoRa antenna 16 of the data transmission unit, ensuring compatibility with both wireless communication methods.
