Description

Technical Field

[0001] This invention belongs to the field of optical fiber testing technology, specifically relating to a modular distributed optical fiber testing device. Background Technology

[0002] Optical fiber, a high-precision transmission medium, is a fiber made of glass or plastic that serves as a means of light transmission. At one end of the fiber, a transmitting device uses a light-emitting diode or a laser beam to transmit light pulses, while at the other end, a receiving device uses a photosensitive element to detect the pulses. Because the transmission loss of light in optical fibers is much lower than that of electricity in wires, optical fibers are frequently used for long-distance information transmission. Their high-quality transmission rates have led to their increasingly widespread use in communications and home applications.

[0003] If cracks, delamination, or uneven stress distribution occur inside special pipelines during production, it will affect their subsequent use. Therefore, it is necessary to monitor and detect internal defects in special pipelines during production. However, existing detection devices rely solely on external observation or internal lighting, which is not convenient for real-time detection of internal defects in pipelines, leading to breakage or leakage during subsequent use. Utility Model Content

[0004] The purpose of this invention is to provide a modular distributed optical fiber detection device. By fixing the optical fiber inside the pipe and applying external force to the pipe through the detection mechanism to cause the pipe to deform, the device can effectively monitor whether cracks and breaks occur inside the pipe by recording the signal peak transmitted by the optical fiber.

[0005] The specific technical solution adopted by this utility model is as follows: A modular distributed optical fiber detection device includes a support platform, a slide rail fixed to the top of the support platform, the slide rail being slidably connected to a drive block, the drive block being fixedly connected to a fixing plate, a fixing groove being provided on the fixing plate, and a pressure plate being rotatably connected above the fixing groove. The testing mechanism includes a port connector and a signal receiver. The port connector is slidably connected to one side of the top of the support platform, and the port connector has multiple connection ports on the side near the fixed plate. The signal receiver is slidably connected to the other side of the top of the support platform, and the signal receiver has a receiving port on the side near the fixed plate. The upper part of the receiving port is rotatably connected to one end of the clamping plate.

[0006] Furthermore, a sliding groove is provided on one side of the top of the support platform. The sliding groove is slidably connected to the bottom of the port connector, and a drive push rod is fixed in the sliding groove. The output end of the drive push rod is fixedly connected to the port connector.

[0007] Furthermore, the detection mechanism also includes a test plate, which is fixedly connected to one side of the fixed plate and located on the side of the fixed plate closer to the signal receiver, and multiple detection rods are slidably connected to the test plate.

[0008] Furthermore, the bottoms of the plurality of detection rods are respectively fixedly connected to the tops of the plurality of sliding racks, and the plurality of sliding racks are slidably connected inside the test plate.

[0009] Furthermore, multiple sliding racks are engaged with drive teeth, which are rotatably connected to the interior of the test plate. The bottom of each drive tooth is fixedly connected to the output end of a drive motor, which is fixed inside the support platform.

[0010] Furthermore, a display screen and indicator lights are fixed to the top of the signal receiver.

[0011] The technical effects achieved by this utility model are as follows: This utility model discloses a modular distributed optical fiber detection device. Through the test rod set in the detection mechanism, it can effectively apply external force to the pipeline, causing the pipeline to bend and deform. At the same time, by recording the peak value of the optical fiber signal, it can effectively detect whether the pipeline has broken or cracked. When the pipeline has broken or cracked inside, the optical fiber located in the pipeline will break due to micro-bending, causing the optical fiber signal to reflect peak or light intensity to attenuate, thus accurately identifying the crack inside the pipeline.

[0012] This utility model discloses a modular distributed optical fiber detection device that monitors the real-time signal transmitted by light to effectively determine whether the internal performance of a pipeline is stable under stress. By applying pressure to different locations in the pipeline, it can effectively assess the bending sensitivity of the pipeline. Attached Figure Description

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figures 1 to 4 As shown, a modular distributed optical fiber detection device includes a support platform 10, a slide rail 11 fixed on the top of the support platform 10, the slide rail 11 being slidably connected to a drive block 111, the drive block 111 being fixedly connected to a fixing plate 12, a fixing groove 121 being provided on the fixing plate 12, and a pressure plate being rotatably connected above the fixing groove 121. The testing mechanism 20 includes a port connector 21 and a signal receiver 22. The port connector 21 is slidably connected to one side of the top of the support platform 10, and the port connector 21 has multiple connection ports 211 on the side near the fixing plate 12. The signal receiver 22 is slidably connected to the other side of the top of the support platform 10, and the signal receiver 22 has a receiving port 221 on the side near the fixing plate 12. The upper part of the outer side of the receiving port 221 is rotatably connected to one end of the clamping plate.

[0017] In this embodiment, it should be noted that the slide rail 11 has a scale line on the side fixed to the support platform 10. The position of the scale line corresponds to the connection port 211 on the port connector 21. The drive block 111 is an axial drive element that can effectively move above the slide rail 11. This is a conventional technical means and will not be described in detail here. Specifically, by fixing the pipe to the optical fiber interface, when the optical fiber interface is located inside the fixing groove 121 on the fixing plate 12, it is fixed by using a pressure plate. Subsequently, the drive block 111 drives the fixing plate 12 and the pipe. The fiber optic interface is moved to the corresponding connection port 211. The connection port 211 is moved by controlling the port connector 21 to effectively connect the connection port 211 to the fiber optic port, thereby completing the transmission of signals from the fiber optic cable. In particular, by connecting the interface at the other end of the pipe to the receiving port 221 on the signal receiver 22, and fixing the pipe by the clamping plate at the receiving port 221, it can be ensured that the signal receiver 22 can effectively receive the signal transmitted by the fiber optic cable, and test the peak value of the fiber optic signal transmission when the pipe is deformed, so as to monitor whether there are defects inside the pipe in real time.

[0018] like Figure 3 , Figure 4 As shown, a sliding groove 101 is provided on one side of the top of the support platform 10. The sliding groove 101 is slidably connected to the bottom of the port connector 21, and a drive push rod 102 is fixed in the sliding groove 101. The output end of the drive push rod 102 is fixedly connected to the port connector 21. The drive push rod 102 can effectively drive the port connector 21 to move in the sliding groove 101, so that the connection port 211 can be effectively connected to the optical fiber interface at the pipe port, ensuring the stability of optical fiber signal transmission.

[0019] like Figure 2 As shown, the testing mechanism 20 also includes a test plate 23, which is fixedly connected to one side of the fixed plate 12 and located on the side of the fixed plate 12 closer to the signal receiver 22. Multiple testing rods 24 are slidably connected on the test plate 23.

[0020] Preferably, the bottom of the plurality of detection rods 24 is fixedly connected to the top of the plurality of sliding racks 241, and the plurality of sliding racks 241 are slidably connected to the inside of the test plate 23. Specifically, the detection rods 24 can effectively apply external force to the pipeline, effectively drive the pipeline to bend and deform, test whether the pipeline breaks or cracks when subjected to force, and at the same time, can effectively determine the bending radius of the pipeline, thereby avoiding excessive bending of the pipeline during use, which may lead to pipeline breakage.

[0021] like Figure 3 , Figure 4 As shown, multiple sliding racks 241 are meshed with drive teeth 25, drive teeth 25 are rotatably connected to the inside of test plate 23, and the bottom of drive teeth 25 is fixedly connected to the output end of drive motor 251, drive motor 251 is fixed inside support platform 10; it should be noted that multiple sliding racks 241 are arranged in a central array along drive teeth 25.

[0022] In the above embodiment, based on the previous embodiment, it should be noted that an elastic element is assembled between the signal receiver 22 and the support platform 10 on the side away from the receiving port 221. When the optical fiber interfaces at both ends of the pipe are connected to the port connector 21 and the signal receiver 22 respectively, the drive motor 251 is controlled to drive the drive teeth 25 to mesh with the sliding racks 241 on both sides, thereby driving the sliding racks 241 and the detection rod 24 to move, applying force to both sides of the pipe, causing the pipe to bend and deform. When the pipe bends and deforms, it can drive the signal receiver 22 to move, and at the same time stretch the elastic element, causing elastic deformation. After the bending detection is completed, the signal receiver 22 is not subjected to external force, and through the rebound action, it can drive the signal receiver 22 to reset.

[0023] Preferably, a signal light and a display screen are fixed on the top of the signal receiver 22. It should be noted that when the fiber optic signal transmission is connected, the signal light will light up, and the display screen can effectively record the peak value and data fluctuation of the fiber optic signal transmission. The signal receiver 22 has an internal effective conversion module that can effectively convert the output signal of the fiber optic cable. This is a conventional technical means and will not be described in detail here.

[0024] The working principle of this utility model is as follows: When pipeline inspection is required, the fiber optic interface at one end of the pipeline is connected to the receiving port 221 on the signal receiver 22. The clamping plate then effectively fixes the pipeline to the connection port 211. Next, the interface at the other end of the pipeline is placed in the fixing groove 121 on the fixing plate 12. The pressure plate then fixes the pipeline and interface within the fixing groove 121. The driving block 111 moves the fixing plate 12 to the connection port 211 corresponding to the fiber optic port. Then, the drive push rod 102 moves the port connector 21, connecting the connection port 211 to the fiber optic cable at the end of the pipeline. The port is connected to transmit signals to the optical fiber. Then, the drive motor 251 is controlled to drive the drive gear 25, which meshes with the sliding racks 241 on both sides, causing the detection rod 24 to slide on the test plate 23 and apply force to the pipeline. This can effectively test whether the pipeline will break or crack when it is deformed and bent by external force. The peak value of the optical fiber signal can be effectively recorded on the display screen on the signal receiver 22. When the pipeline breaks or cracks inside, the optical fiber inside the pipeline will break due to micro-bending, causing the optical fiber signal to reflect peaks or light intensity to attenuate, thus accurately identifying cracks inside the pipeline.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
