Description
Technical Field
[0001] The present invention relates to the technical field of network accessories detection, in particular to an optical fiber breakage detection device for computer networks. Background Art
[0002] As a vital medium for data transmission, the quality and stability of optical fiber cables are crucial to the reliability of the entire network system. During the production process, optical fibers may develop minor breaks due to various factors. If these breaks are not detected and addressed promptly, they can severely impact the normal operation of the network. Therefore, it is particularly important to perform break detection on produced optical fibers.
[0003] Currently, data continuity testing is widely used to detect broken optical fibers. This method uses a test instrument to connect optical fibers and measure optical signal parameters to determine whether the fiber is connected or broken.
[0004] However, existing data continuity testing technology still has some shortcomings. First, while it can detect the continuity and disconnection of optical fibers, it often cannot simulate the various bending conditions that optical fibers experience in actual use, particularly the changes in optical fiber performance at different bend angles. Therefore, existing technology may not be able to effectively detect subtle breaks in optical fibers that may occur at specific bend angles.
[0005] Therefore, it is necessary to provide an optical fiber break detection device for computer networks, which will help improve the accuracy and reliability of optical fiber break detection and provide strong guarantee for the stable operation of computer networks. Summary of the Invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] In the present invention, an infrared laser generated by a light source is used to illuminate the surface of the optical fiber, and a laser sensor is used to receive and analyze the reflected signal. The light transmission detection component can accurately determine whether the optical fiber is broken or damaged. This non-contact detection method not only avoids physical damage to the optical fiber, but also can detect tiny defects inside the optical fiber, thereby improving the sensitivity and reliability of detection.
[0020] In this invention, the bending assembly simulates the bending state of an optical fiber in actual use by forcing it through an S-bend, thereby detecting fiber breakage in this state. The curvature and arc length of the bend can be adjusted based on the fiber's diameter, deflection, and usage scenario. The bonding assembly, on the other hand, bonds to the fiber surface for testing, applying a vibration signal and receiving a feedback signal to determine the fiber's integrity. The combination of these functions enables this device to achieve greater accuracy and reliability in detecting fiber breakage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0026] See also Figure 1 In an embodiment of the present invention, a device for detecting optical fiber breakage for a computer network includes a base 1. A pay-off reel 2 is rotatably provided at the front end of the base 1. A light transmission detection component 3 is provided behind the pay-off reel 2. A guide cylinder 4 is provided behind the light transmission detection component 3. Two bending components 6 are provided behind the guide cylinder 4. A fitting component 7 is provided on one side of each of the two bending components 6. A take-up reel 10 is provided at the rear end of the base 1.
[0027] The optical fiber to be inspected is wound onto the payout reel 2, passing through the light transmission detection assembly 3 and the guide drum 4, and then around two bending assemblies 6 before being wound onto the take-up reel 10. The take-up reel 10 can be driven by a motor to actively rotate to continuously reel in the optical fiber. The light transmission detection assembly 3 can detect internal defects in the optical fiber by transmitting light. The two bending assemblies 6 can bend the optical fiber into an S-bend to detect the bent optical fiber. The bonding assembly 7 can be bonded to the surface of the optical fiber for inspection.
[0028] In this embodiment, the guide cylinder 4 is pivotally connected to the base 1. An hourglass-shaped guide wheel 5 supports the guide cylinder 4 from below. A guide telescopic cylinder is connected to one side of the guide wheel 5. By adjusting the position of the guide wheel 5, the guide cylinder 4 can be swung, adjusting the entry point of the optical fiber in the guide cylinder 4 into the bending assembly 6.
[0029] In this embodiment, a heating tube is provided in the guide tube 4 so as to heat the optical fiber to a certain temperature in the guide tube 4 to improve the bending ability of the optical fiber.
[0030] See also Figure 2 In this embodiment, the light transmission detection assembly 3 includes a sealed box 31 with a through hole in the center thereof through which an optical fiber can pass. A light source 32 and a laser sensor 34 are respectively provided on either side of the through hole. The light source 32 generates an infrared laser, which is then irradiated onto the surface of the optical fiber to be detected. The laser interacts with the optical fiber surface, causing some of the light energy to be reflected, scattered, or absorbed. The laser sensor 34 is used to receive the signal generated by the optical fiber surface after being irradiated by the laser and analyze the received signal. When the optical fiber is in a normal state, the received signal should be stable. However, when the optical fiber is broken, bent, or damaged, the received signal will change. Such changes may include changes in the intensity of the reflected signal, a shift in the signal frequency, or a time delay.
[0031] A fixed cylinder 33 is fixed to the side of the housing 31 away from the light source 32. The laser sensor 34 is disposed within the fixed cylinder 33. A sliding cylinder 35 is provided on the other side of the housing 31, slidably and rotationally restricted, surrounding the fixed cylinder 33. A focusing lens 36 is secured within the sliding cylinder 35. Lens 36 focuses the laser beam onto the surface of the optical fiber, ensuring that the optical fiber effectively receives the laser signal and generates corresponding feedback. The focal length of the lens can be adjusted based on parameters such as the optical fiber diameter and distance to ensure that the laser beam covers the optical fiber without spilling.
[0032] The outer wall of the sliding cylinder 35 is threadedly connected to a rotating sleeve 37, which is rotatably connected to the housing 31. A bevel gear ring 38 is fixed to the rotating sleeve 37. A bevel gear 39 is provided at the top of the housing 31, meshing with the bevel gear ring 38. The bevel gear 39 can be driven for rotation by a drive motor 310. In other words, the drive motor 310 can rotate the rotating sleeve 37, causing the sliding cylinder 35 to slide, thereby changing the distance between the lens 36 and the light source 32.
[0033] In this embodiment, one of the two bending assemblies 6 is slidably connected to a slideway 8 via a slide 9. A sliding and telescopic cylinder is connected between the slide 9 and the base 1. By sliding the slide 9, the offset position of the two bending assemblies 6 can be changed, thereby adjusting the arc length of the optical fiber passing through the two bending assemblies 6.
[0034] See also Figure 3 In this embodiment, the bending component 6 includes a connecting disk 61, and a plurality of radially extending sliding grooves 63 are distributed on the connecting disk 61, and a leaf 62 is slidably connected to each sliding groove 63.
[0035] Each leaf 62 is hingedly connected to a connecting rod 64 on one side near the axis of the connecting disk 61. Each connecting rod 64 is hingedly connected to a hinge disk 65. A lifting cylinder 66 is provided at the axis of the connecting disk 61, and the piston rod of the lifting cylinder 66 is fixed to the hinge disk 65. In other words, the lifting cylinder 66 raises and lowers the hinge disk 65, synchronously driving each leaf 62 to slide, changing the radius of the ring formed by the leaves 62, thereby adjusting the curvature of the optical fiber passing through the two bending assemblies 6.
[0036] See also Figure 4 In this embodiment, the fitting component 7 includes two symmetrically arranged rotatable clamping arms 71, and a gear 72 is fixed at the rotating shaft of the clamping arms 71. The gears 72 of the two clamping arms 71 are meshed with each other.
[0037] A push cylinder 75 is hinged between one of the clamping arms 71 and the base 1 or the slide 9. The two clamping arms 71 can be driven by the push cylinder 75 to adjust the clamping radius.
[0038] One of the clamping arms 71 is provided with a vibration generator 73 at one end near the bending assembly 6, and the other clamping arm 71 is provided with a signal receiver 74 at one end near the bending assembly 6. When the clamping arm 71 clamps the optical fiber attached to the bending assembly 6, a vibration signal is applied to the optical fiber via the vibration generator 73, and a feedback signal caused by the vibration signal is received by the signal receiver 74 at another location on the optical fiber. When the optical fiber is intact, the vibration signal should propagate in a certain manner. However, when the optical fiber is broken, the propagation path of the vibration signal will be affected, causing the received feedback signal to change. By analyzing the changes in the feedback signal, the approximate location of the optical fiber break can be determined by measuring parameters such as the signal strength, frequency, or time delay.
[0039] When implementing:
[0040] First, the optical fiber to be tested is wound into the pay-out reel 2. The optical fiber passes through the light transmission detection component 3 and the guide drum 4 in sequence, and bypasses the two bending components 6, and is finally wound into the take-up reel 10. The ends of the optical fibers in the pay-out reel 2 and the take-up reel 10 are respectively connected to the optical fiber signal generator and the receiver. During the whole process, the take-up reel 10 is actively rotated by the motor to ensure that the optical fiber can be wound continuously and stably.
[0041] The light transmission detection component 3 uses the infrared laser generated by the light source 32 to irradiate the surface of the optical fiber. After the laser interacts with the surface of the optical fiber, the laser sensor 34 will receive a corresponding feedback signal. When the optical fiber is in a normal state, the received signal is stable; when the optical fiber is broken, bent or damaged, the received signal will change. These changes will be captured and analyzed by the light transmission detection component 3 to determine the state of the optical fiber.
[0042] By adjusting the position of the guide wheel 5, the swing angle of the guide cylinder 4 can be changed, thereby adjusting the entry point of the optical fiber into the bending assembly 6; in addition, a heating tube is provided in the guide cylinder 4, which can heat the optical fiber to a certain temperature, thereby improving the bending ability of the optical fiber and reducing damage caused by bending during the detection process.
[0043] The bending assembly 6 makes the optical fiber bypass an S-bend to detect whether there is any breakage in the optical fiber in the bent state. The offset position of the two bending assemblies 6 can be adjusted by sliding the slide 9, thereby changing the arc length of the optical fiber bypass; each bending assembly 6 is composed of a connecting disk 61 and a plurality of leaves 62. By driving the lifting cylinder 66, the radius of the ring formed by the leaves 62 can be changed, thereby adjusting the curvature of the optical fiber bypass.
[0044] The bonding component 7 is used to bond to the surface of the optical fiber for testing. By pushing the cylinder 75, the two clamping arms 71 can be driven to adjust the clamping radius to adapt to optical fibers of different diameters. The clamping arms 71 are also provided with a vibration generator 73 and a signal receiver 74. By applying a vibration signal to the optical fiber and receiving a feedback signal, it can be determined whether the optical fiber has defects.
[0045] During the entire detection process, the light transmission detection component 3, the bending component 6 and the bonding component 7 work together to comprehensively and accurately detect the status of the optical fiber. Once the optical fiber is detected to be broken or otherwise damaged, the equipment will immediately issue an alarm to remind the operator to handle it.
[0046] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
