Description

Technical Field

[0001] This utility model belongs to the field of optical cable inspection technology, specifically a hook-type overhead optical cable inspection device. Background Technology

[0002] During daily operation, OPGW fiber optic composite overhead ground wires (O-cables) are susceptible to damage to the fiber cores caused by external factors such as tension, vibration, and lightning strikes, affecting internal power communication. Accurate fault location and repair are the two main factors affecting repair time during the entire maintenance process. Current methods requiring power outages for fault location are time-consuming. A solution combining drones and fiber optic cable identification devices can achieve accurate fault location without power interruption, significantly reducing fault location time.

[0003] The existing hook-type overhead optical cable verification device has several drawbacks during use. First, the simple hook structure is not securely fixed to the optical cable and is prone to falling off due to external factors such as wind, which cannot guarantee the continuity of the verification work. Second, the friction between the device and the optical cable is insufficient, and it is prone to slippage under external interference, affecting the accuracy of the verification.

[0004] Therefore, a hook-type overhead optical cable inspection device is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a hook-type overhead optical cable inspection device, which has the advantages of effectively resisting external interference such as wind, significantly reducing the risk of accidental drop of the device, significantly improving the stability of use, and effectively preventing the inspection device from sliding on the optical cable, thereby improving the stability and accuracy of the inspection process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hook-type overhead optical cable calibration device, comprising a calibration device body, the calibration device body being hook-shaped, a mounting frame installed at the top of the calibration device body for connecting a drone, an identification device body installed below the calibration device body, and two clamping rods slidably connected to both sides of the inner surface of the calibration device body, one end of each clamping rod penetrating one side of the inner wall of the calibration device body and extending to the outside of the calibration device body, two mirror-distributed brackets fixedly connected to the outer surface of the calibration device body, the inner surfaces of the two brackets slidably sleeved with the two clamping rods respectively, top plates fixedly sleeved on the outer surfaces of the two clamping rods outside the calibration device body, and return springs wound around the outer surfaces of the two clamping rods outside the calibration device body, one end of each return spring fixedly connected to one end of each of the two top plates, and the other end of each return spring fixedly connected to one side of the inner wall of each of the two brackets respectively.

[0007] Preferably, a limiting plate is fixedly connected to one end of each of the two clamping rods facing away from each other, and the two limiting plates are respectively attached to one end of the two brackets.

[0008] Preferably, ball bearings are installed at the corresponding ends of the two clamping rods.

[0009] Preferably, the outer surfaces of both balls are coated with a lubricating layer.

[0010] Preferably, the outer surfaces of the two clamping rods are provided with two guide grooves, and the inner surfaces of the two brackets are fixedly connected with guide blocks that cooperate with the two guide grooves. The cross-sections of the two guide blocks and the two guide grooves are rectangular.

[0011] Preferably, the inner arc surface of the calibration device body is provided with anti-slip texture.

[0012] Preferably, the anti-slip texture consists of regularly arranged serrations.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model features a reset spring, which allows for easy installation by snapping the device in from top to bottom and easy removal by pulling it upwards. The spring force of the reset spring keeps the clamping rod in a stable locked state, effectively resisting external interference such as wind, greatly reducing the risk of the device falling accidentally, and significantly improving its stability.

[0015] 2. This utility model provides anti-slip textures composed of regularly arranged serrations on the inner arc surface of the calibration device. When the anti-slip textures come into contact with the optical cable, the friction between the device and the optical cable is increased, effectively preventing the calibration device from sliding on the optical cable and improving the stability and accuracy of the calibration process.

[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] like Figures 1 to 5 As shown, this utility model provides a hook-type overhead optical cable verification device, including a verification device body 1, which is hook-shaped. A mounting frame 2 is installed at the top of the verification device body 1, which is used to connect a drone. By connecting the drone to the mounting frame 2, no manual high-altitude operation is required, improving the convenience and safety of operation. An identification device body 3 is installed below the verification device body 1. The identification device body 3 can receive the wireless signal from the ground remote controller and generate a specific frequency and pattern of jogging or continuous vibration as needed. The vibration is transmitted to the optical cable through the device. In this way, in conjunction with an optical cable survey instrument to capture the vibration signal, the device can perform verification work such as locating the optical cable and identifying the optical cable and ground wire in the case of double circuit on the same tower. Two clamping rods 41 are slidably connected to both sides of the inner surface of the verification device body 1. One end of each clamping rod 41 penetrates one side of the inner wall of the verification device body 1 and extends... Extending out of the calibration device body 1, two mirror-shaped brackets 4 are fixedly connected to the outer surface of the calibration device body 1. The inner surfaces of the two brackets 4 are slidably sleeved with two clamping rods 41. Top plates 44 are fixedly sleeved on the outer surfaces of the two clamping rods 41 outside the calibration device body 1. Return springs 42 are wound around the outer surfaces of the two clamping rods 41 outside the calibration device body 1. One end of the two return springs 42 is fixedly connected to one end of the two top plates 44, and the other end of the two return springs 42 is fixedly connected to one side of the inner wall of the two brackets 4. With the cooperation of the return springs 42 and the clamping rods 41, the device can be easily fixed by snapping it in from top to bottom and removed by pulling it upward. At the same time, the elasticity of the return springs 42 can keep the clamping rods 41 in a stable locked state, effectively resisting external interference such as wind, greatly reducing the risk of the device falling accidentally, and significantly improving the stability of use.

[0028] Specifically, each of the two clamping rods 41 has a limiting plate 43 fixedly connected to one end of its back-to-back. The two limiting plates 43 are respectively attached to one end of the two brackets 4. The attachment of the limiting plates 43 to the brackets 4 can effectively limit the sliding stroke of the clamping rods 41, prevent the clamping rods 41 from slipping off the brackets 4 due to excessive sliding, ensure the integrity of the elastic fixing structure formed by the clamping rods 41 and the return spring 42, further ensure the stable locking state of the device, and enhance the anti-falling effect.

[0029] like Figures 1 to 5 As shown, each of the two clamping rods 41 has a ball bearing 412 installed at one end. The ball bearing 412 at the end of the clamping rod 41 transforms the sliding friction between the clamping rod 41 and the optical cable into rolling friction. During the installation, fixing and adjustment of the device, the frictional damage of the clamping rod 41 to the surface of the optical cable is reduced, and the movement of the clamping rod 41 is made smoother, improving the ease of operation.

[0030] Furthermore, the outer surfaces of both balls 412 are coated with a lubricating layer. The lubricating layer on the outer surface of the balls 412 further reduces the rolling friction coefficient, making the balls 412 roll more flexibly and smoothly, reducing the resistance of the clamping rod 41 during the sliding process under force, which not only improves the convenience of device installation and disassembly, but also further reduces the wear on the surface of the optical cable.

[0031] like Figures 1 to 5 As shown, two guide grooves 411 are formed on the outer surface of each of the two clamping rods 41, and guide blocks 45 that cooperate with the two guide grooves 411 are fixedly connected to the inner surface of each of the two brackets 4. The cross-sections of the two guide blocks 45 and the two guide grooves 411 are rectangular. The cooperation between the rectangular guide grooves 411 and the guide blocks 45 can accurately limit the sliding direction of the clamping rods 41, prevent the clamping rods 41 from rotating or deviating under the action of the return spring 42 or when subjected to external interference, and ensure that the clamping rods 41 always slide stably along the preset trajectory, thus ensuring the accuracy and stability of the clamping rods 41 in engaging the optical cable.

[0032] It is worth noting that the inner arc surface of the calibration device body 1 is provided with anti-slip texture 11. The anti-slip texture 11 on the inner arc surface of the calibration device body 1 increases the friction between the device and the optical cable, which can effectively prevent the calibration device from sliding on the optical cable due to external factors such as wind and vibration, improve the stability of the relative position between the device and the optical cable during the calibration process, and ensure the accuracy of the calibration.

[0033] like Figures 1 to 5 As shown, the anti-slip texture 11 is composed of regularly arranged serrations. Compared with ordinary anti-slip structures, the anti-slip texture 11 composed of regularly arranged serrations can form a more effective mechanical engagement, significantly enhancing the friction with the surface of the optical cable, further improving the anti-slip performance of the device, ensuring that the device can remain stable in complex environments, and providing a more reliable guarantee for the accuracy of the calibration.

[0034] Working principle and process: The hook-type overhead optical cable calibration device is connected to the UAV via the mounting frame 2 and carried by the UAV to the overhead optical cable. During installation, the hook-shaped calibration device body 1 is inserted into the optical cable from top to bottom. During the process, the clamping rod 41 is subjected to force, causing the return spring 42 to undergo elastic deformation. After the device is in place, the elastic force of the return spring 42 causes the clamping rod 41 to return to its original position. The elastic force of the return spring 42 can keep the clamping rod 41 in a stable locked state, which can effectively resist external interference such as wind. The limiting plate 43 restricts the excessive sliding of the clamping rod 41, the guide groove 411 and the guide block 45 ensure the stable sliding of the clamping rod 41, and the ball bearing 412 and the lubrication layer reduce friction and wear during operation. The serrated anti-slip texture 11 on the inner arc surface of the calibration device body 1 increases the friction with the optical cable and prevents the device from sliding. Once fixed, the identification device 3 below will work, working in conjunction with the optical cable survey instrument to verify the optical cable; during disassembly, the drone can pull the device upward to overcome the spring force of the reset spring 42 and open the clamp 41 to complete the removal.
