Description

Technical Field

[0001] This utility model relates to the field of communication cable bending radius detection technology, and in particular to a communication cable bending radius detection device. Background Technology

[0002] Communication cables are used to transmit telephone, telegram, fax documents, television and radio programs, data and other electrical signals. During the laying and use of communication cables, the bending radius is a key parameter affecting their transmission performance and lifespan. With the construction of 5G networks and the large-scale deployment of data centers, the requirements for the installation quality of communication cables are becoming increasingly stringent. Traditional testing methods can no longer meet the needs of high-precision and high-efficiency testing. Therefore, a communication cable bending radius testing device is needed.

[0003] A communication cable bending radius testing device is an instrument used to measure and evaluate whether the bending degree of communication cables meets the standard requirements, ensuring that the cable performance is not damaged, guaranteeing its service life, ensuring that cable installation complies with standard specifications, and improving construction efficiency and quality. In existing technologies, cable bending radius testing is generally carried out by manual visual inspection or simple measuring tools, which has the problems of high subjectivity and low accuracy. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a communication cable bending radius detection device, which aims to improve the problem of high subjectivity and low accuracy in the existing technology of manually visually inspecting or using simple measuring tools to detect bending radius.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a communication cable bending radius detection device, comprising a C-shaped frame, a slider slidably connected to the inner wall of the C-shaped frame, a connecting plate slidably connected to the inside of the slider, a rotating shaft rotatably connected to the inside of the connecting plate, a displacement sensor disposed inside the slider, a movable measuring wheel fixedly connected to the outer wall of the rotating shaft, a spring disposed inside the slider, one end of the spring fixedly connected to the inside of the slider, the other end of the spring fixedly connected to the outer wall of the connecting plate, an angle encoder disposed on the outer wall of the rotating shaft, a support frame fixedly connected to the lower surface of the C-shaped frame, a fixed measuring wheel disposed on the upper surface of the support frame, and a disassembly assembly disposed inside the support frame.

[0006] The above technical solution involves placing the cable between a movable measuring wheel and a fixed measuring wheel. The movable measuring wheel adheres tightly to the outer wall of the cable due to the elasticity of a spring. When the cable bends, the movable measuring wheel causes the slider to slide along the inner wall of the C-shaped frame. A displacement sensor can measure the offset change of the movable measuring wheel. As the movable measuring wheel moves, the outer wall slides and rotates along the outer wall of the cable. The rotation of the movable measuring wheel causes the rotating shaft to rotate. An angle encoder records the rotation angle of the movable measuring wheel in real time through the rotation of the shaft. The geometric relationship between the displacement and rotation angle of the movable measuring wheel measured by the displacement sensor and the angle encoder can be used to calculate the cable bending radius, thus achieving continuous dynamic detection of the cable bending radius.

[0007] As a further description of the above technical solution:

[0008] The disassembly assembly includes a fixed shaft, the outer wall of which is slidably connected to the inside of the support frame, the outer wall of which is slidably connected to the inside of the fixed measuring wheel, a limiting piece is engaged with the outer wall of the disassembly assembly, the upper surface of the limiting piece is fixedly connected to the inside of the support frame, one end of a second spring is fixedly connected to the outer wall of the limiting piece, and the other end of the second spring is fixedly connected to the inner wall of the support frame.

[0009] The above technical solution involves a groove on the lower side of the fixed shaft, and two protruding parts of the limiting plates forming a clamping point. The protruding parts of the limiting plates engage with the groove of the fixed shaft, thus clamping and limiting the fixed shaft and stabilizing it inside the support frame. At the same time, the fixed shaft clamps and fixes the fixed measuring wheel. When the fixed shaft is rotated to disengage the groove from the protruding parts of the limiting plates, the fixed shaft can be removed, achieving the function of quickly disassembling and replacing the fixed measuring wheel.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the C-shaped frame is fitted with a clamping block, the outer wall of the clamping block is fixedly connected to a sliding plate, the outer wall of the sliding plate is slidably connected to a support block, the outer wall of the sliding plate is slidably connected to a rotating disk, the outer wall of the rotating disk is fixedly connected to a connecting column, the outer wall of the connecting column is rotatably connected to the inside of the support block, and the inner wall of the clamping block is provided with a spring.

[0012] The above technical solution involves rotating the disc to move two sliding plates up and down, which in turn causes two clamping blocks to move up and down. When the two clamping blocks move in opposite directions, they achieve a clamping effect, and when they move in opposite directions, the clamping effect is released. By clamping and fixing or releasing the clamping blocks, the C-shaped frame can be replaced or disassembled, effectively reducing the size of the equipment and making it easier to carry. At the same time, the C-shaped frame can be replaced, reducing costs.

[0013] As a further description of the above technical solution:

[0015] The above technical solution provides a fixed support column for the support block, which further ensures the stable operation of the C-shaped frame. The wheels allow for movement, enabling the equipment to work more efficiently. Pushing the movement handle allows the equipment to be moved to the desired measurement location, saving manpower.

[0016] As a further description of the above technical solution:

[0017] The base is equipped with an industrial computer, which consists of a system self-test module, a data acquisition module, a radius calculation module, an alarm module, and a data storage management module.

[0018] Through the above technical solution: the system self-test module ensures system stability and reliability, the data acquisition module collects data, the radius calculation module calculates relevant radius parameters based on the data, the alarm module alarms when data is abnormal, and the data storage and management module is responsible for storing and managing various types of data. Through the collaborative work of each module, high-precision automatic detection, real-time alarm and data traceability of cable bending radius are achieved, ensuring that cable installation quality meets standards and improving project safety and efficiency.

[0019] As a further description of the above technical solution:

[0020] The data acquisition module consists of a displacement sensor and an angle encoder. The output signal of the system self-test module is connected to the input of the data acquisition module. The output signal of the data acquisition module is connected to the input of the radius calculation module. The output signal of the radius calculation module is connected to the input of the touch screen.

[0021] The above technical solution involves using a displacement sensor and an angle encoder to measure the geometric relationship between wheel displacement and rotation angle in real time, calculating the cable bending radius using a built-in algorithm in the radius calculation module, and sending the calculation result to a touch screen to display the cable bending radius, thereby achieving accurate detection and real-time monitoring.

[0022] As a further description of the above technical solution:

[0023] The output signal of the radius calculation module is connected to the input of the data storage management module.

[0024] Through the above technical solution: after the radius calculation module calculates the real-time bending radius value of the cable, it transmits the data to the data storage management module. The data storage management module can save the data for subsequent data traceability.

[0025] As a further description of the above technical solution:

[0026] The output signal of the radius calculation module is connected to the input signal of the alarm module, the output signal of the alarm module is connected to the input signal of the data storage management module, and the output signal of the data storage management module is connected to the data input signal of the touch screen, for transmitting the stored data to the touch screen for display.

Simultaneously, the alarm module feeds back the alarm information to the data storage management module, which stores the data and transmits it to the display screen, allowing staff to view the data.

[0040] 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.

[0041] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a communication cable bending radius detection device, including a C-shaped frame 1, a slider 2 slidably connected to the inner wall of the C-shaped frame 1, a connecting plate 3 slidably connected to the inside of the slider 2, a rotating shaft 4 rotatably connected to the inside of the connecting plate 3, a displacement sensor disposed inside the slider 2, a movable measuring wheel 5 fixedly connected to the outer wall of the rotating shaft 4, a spring 6 disposed inside the slider 2, one end of the spring 6 fixedly connected to the inside of the slider 2, the other end of the spring 6 fixedly connected to the outer wall of the connecting plate 3, an angle encoder 9 disposed on the outer wall of the rotating shaft 4, a support frame 7 fixedly connected to the lower surface of the C-shaped frame 1, a fixed measuring wheel 8 disposed on the upper surface of the support frame 7, and a disassembly assembly 10 disposed inside the support frame 7;

[0042] Specifically, the C-shaped frame 1 has a sliding groove inside, which limits and supports the slider 2, allowing it to move along the groove. The slider 2 supports and limits the sliding of the connecting plate 3, which can only move linearly within the slider 2. The connecting plate 3 supports the rotating shaft 4, which can rotate within it. The rotating shaft 4 fixes the movable measuring wheel 5, allowing it to rotate. Spring 6 supports the connecting plate 3, and its elasticity allows the movable measuring wheel 5 to return to its original position after being compressed. Therefore, the cable is placed between the movable measuring wheel 5 and the fixed... After the measuring wheels 8 are positioned, the movable measuring wheel 5 will be pressed tightly against the outer wall of the cable by the action of spring 6. When the cable bends, the movable measuring wheel 5 will move along the groove of the C-shaped frame 1, and the displacement of the wheel body will be measured by the displacement sensor built into the slider 2. The C-shaped frame 1 has a fixing effect on the support frame 7, the support frame 7 has a supporting effect on the fixed measuring wheel 8, and the rotating shaft 4 has a fixing support effect on the angle encoder 9. The angle encoder 9 can measure the displacement through the displacement sensor built into the slider 2 and record the wheel body rotation angle. The cable bending radius can be calculated by measuring the geometric relationship between the displacement of the wheel and the rotation angle, so as to realize the continuous dynamic detection of the cable bending radius.

[0043] Reference Figure 2 The disassembly assembly 10 includes a fixed shaft 1001. The outer wall of the fixed shaft 1001 is slidably connected to the inside of the support frame 7. The outer wall of the fixed shaft 1001 is also slidably connected to the inside of the fixed measuring wheel 8. A limiting piece 1002 is engaged with the outer wall of the disassembly assembly 10. The upper surface of the limiting piece 1002 is fixedly connected to the inside of the support frame 7. One end of a second spring 1003 is fixedly connected to the outer wall of the limiting piece 1002. The other end of the second spring 1003 is fixedly connected to the inner wall of the support frame 7.

[0044] Specifically, the support frame 7 has a limiting offset function on the fixed shaft 1001, allowing the fixed shaft 1001 to move up and down only inside the support frame 7. The lower outer wall of the fixed shaft 1001 has an inwardly folded L-shaped groove. When the fixed shaft 1001 slides from the inside of the fixed measuring wheel 8 into the inside of the support frame 7, the fixed shaft 1001 will press against the limiting plate 1002. The limiting plate 1002 is elastic, and after being pressed, it will press against the second spring 1003. When the lower groove of the fixed shaft 1001 slides to the protrusion of the limiting plate 1002, the pressing disappears, and the limiting plate 1002... 02 and spring 1003 will return to their original positions through elastic force. At this time, the protrusion of the limiting plate 1002 will be stuck in the groove of the fixed shaft 1001, limiting the fixed shaft 1001. When the fixed shaft 1001 is limited, the upper side of the fixed shaft 1001 will clamp the fixed measuring wheel 8. When the fixed measuring wheel 8 needs to be replaced, the fixed shaft 1001 is rotated 90 degrees. After the fixed shaft 1001 is rotated, it will squeeze the limiting plate 1002. The groove of the fixed shaft 1001 will disengage from the protrusion of the limiting plate 1002. At this time, the fixed shaft 1001 can be removed and the size of the fixed measuring wheel 8 can be replaced.

[0045] Reference Figure 1 and Figure 3 The outer wall of the C-shaped frame 1 is fitted with a clamping block 11, the outer wall of the clamping block 11 is fixedly connected to a sliding plate 12, the outer wall of the sliding plate 12 is slidably connected to a support block 13, the outer wall of the sliding plate 12 is slidably connected to a rotating disk 14, the outer wall of the rotating disk 14 is fixedly connected to a connecting column 15, the outer wall of the connecting column 15 is rotatably connected to the inside of the support block 13, and the inner wall of the clamping block 11 is provided with a spring 16.

[0046] Specifically, the outer wall of the sliding plate 12 has protruding posts, and the interior of the rotating disk 14 has an arc-shaped groove. The groove limits the movement of the protruding posts of the sliding plate 12. The connecting post 15 fixes the rotating disk 14, and the support block 13 supports the connecting post 15. When the connecting post 15 rotates, the rotating disk 14 rotates synchronously. The rotation of the rotating disk 14 drives the sliding plate 12 to move through the groove. The support block 13 limits the movement of the sliding plate 12, allowing it to move up and down only within the inner wall of the support block 13. The clamping block 11... The spring 16 provides support and connects the two clamping blocks 11. When the sliding plate 12 moves up and down, it drives the spring 16 to move synchronously. When the spring 16 moves, it exerts a squeezing and stretching effect. After the connecting column 15 is released, the contraction force generated by the stretching of the spring 16 will cause the clamping block 11 to return to its original position. The contraction force of the spring 16 will cause the clamping block 11 to clamp and fix the C-shaped frame 1. Conversely, the C-shaped frame 1 can be removed and replaced by stretching of the spring 16.

[0047] Reference Figure 1 The lower surface of the support block 13 is fixedly connected to a support column 17. The outer wall of the support column 17 is fixedly connected to a base 18. Wheels 19 are provided on the lower surface of the base 18. An operating handle 20 is fixedly connected inside the base 18. A touch screen 21 is provided on the outer wall of the operating handle 20.

[0048] Specifically, the support column 17 fixes the support block 13, the base 18 fixes the support column 17, the wheels 19 support the base 18. The base 18 can be moved by the wheels 19. The base 18 is in a "convex" shape. The base 18 fixes the operating handle 20, and the operating handle 20 fixes the touch screen 21. The device can be pushed to move through the operating handle 20. The measured data can be viewed through the touch screen 21.

[0049] Refer to Figure 1 、 Figure 4 and Figure 5 An industrial computer is provided inside the base 18. The industrial computer consists of a system self-check module, a data acquisition module, a radius calculation module, an alarm module, and a data storage and management module. The data acquisition module consists of a displacement sensor and an angle encoder 9. The output end of the system self-check module is signal-connected to the input end of the data acquisition module. The output end of the data acquisition module is signal-connected to the input end of the radius calculation module. The output end of the radius calculation module is signal-connected to the input end of the touch screen 21.

[0050] Specifically, when the device is powered on or restarted, the system self-check module is automatically started, and a calibration signal is sent to the displacement sensor to test whether it can correctly feedback displacement data. After the system self-check passes, the device enters the detection standby state. The displacement sensor is used to detect in real time the displacement change data of the movable measuring wheel 5 driving the slider 2 to move when the cable is bent. The data acquisition module converts the wheel body displacement ΔL measured by the displacement sensor and the wheel body rotation angle θ data recorded by the angle encoder 9 into electrical signals and transmits them to the radius calculation module. The radius calculation module receives real-time data signals through the main control CPU of the Intel Atom x6425E model, performs trigonometric function and division operations with hardware acceleration through the FPGA of the Xilinx Artix-7 model, and performs precision compensation through the DSP chip of the TI TMS320 model. Finally, the radius value is output according to the formula R=(ΔL / sinθ)+r. Finally, the radius calculation module transmits the calculated result to the touch screen 21. Through the touch screen 21, the current bending radius and threshold line can be displayed in real time, and at the same time, a trend curve of the radius changing with time can be drawn according to the calculation result, which is convenient for observing the bending stability.

[0051] Refer to Figure 4 and Figure 5The output signal of the radius calculation module is connected to the input of the data storage management module; the output signal of the radius calculation module is connected to the input of the alarm module; the output signal of the alarm module is connected to the input of the data storage management module; and the output signal of the data storage management module is connected to the data input of the touch screen 21, which is used to transmit the stored data to the touch screen 21 for display.

[0052] Specifically, the radius calculation module calculates the actual bending radius of the cable by using a built-in algorithm based on the real-time collected bending parameters. The calculated result is then transmitted to the storage module via the CAN controller. The data storage management module stores the data for historical records and data traceability. Simultaneously, the radius calculation module compares the calculated bending radius with a preset safety threshold. If the threshold is exceeded, an alarm trigger signal is sent to the alarm module. Upon receiving the alarm trigger signal, the alarm module issues a warning or alerts the operator via an audible and visual alarm or buzzer, reminding staff of the abnormal cable bending condition. Simultaneously, the alarm module feeds back relevant information about the alarm event to the data storage management module for recording alarm history. The data storage management module then organizes the real-time and historical data transmitted from the radius calculation module and the alarm module and transmits it to the touchscreen 21. Operators can view the current status, set parameters, or query historical data via the touchscreen 21, enabling monitoring and management of the equipment and providing human-machine interaction. Data can also be exported via the touchscreen 21, allowing data from the data storage management module to be exported to a USB drive.

[0053] Working principle: When the device is needed, push the movable handle 20 to move the device to the cable segment to be tested. Then, place the cable between the movable measuring wheel 5 and the fixed measuring wheel 8. The movable measuring wheel 5 will be pressed tightly against the outer wall of the cable by the action of spring 6. Then, push the touch screen 21 along the cable axis to move the device. When the cable bends, the movable measuring wheel 5 is displaced along the guide groove. The displacement sensor measures the wheel displacement ΔL, and the angle encoder 9 records the wheel rotation angle θ. The real-time bending radius is calculated using the formula R=(ΔL / sinθ)+r, thus realizing the bending of the cable. Continuous dynamic detection of radius: When it is necessary to measure cables of different diameters, rotate the fixed shaft 1001. The fixed shaft 1001 will rotate inside the support frame 7 and squeeze the limiting plate 1002. The limiting plate 1002 being squeezed will squeeze the spring 1003. At the same time, when the fixed shaft 1001 rotates and squeezes the limiting plate 1002, the fixed shaft 1001 and the limiting plate 1002 are no longer locked. At this time, the fixed shaft 1001 can be removed, and the fixed measuring wheel 8 can be replaced to adapt to the needs of measuring cables of different diameters.

[0054] By rotating the connecting column 15, the connecting column 15 will rotate inside the support block 13 and drive the rotating disk 14 to rotate. The outer wall of the rotating disk 14 is provided with a sliding groove. When the rotating disk 14 rotates, it will drive the sliding plate 12 to move up and down inside the support block 13 through the sliding groove. When the sliding plate 12 moves, it will drive the clamping block 11 to move up and down. When the two clamping blocks 11 open outward, the C-shaped frame 1 can be taken out. When the two clamping blocks 11 move inward, the C-shaped frame 1 can be clamped and fixed, which makes it easy to replace the C-shaped frame 1 and also allows for quick disassembly, reducing the size of the equipment and making it easy to carry.

[0055] After the data acquisition module obtains the displacement and rotation data of the movable measuring wheel 5 through the displacement sensor and angle encoder 9, it transmits the measured data to the radius calculation module. The radius calculation module calculates the bending radius value using the received data and transmits the data to the data storage management module for storage. Then, it compares the calculated bending radius value with a preset safety threshold. If the threshold is exceeded, an alarm trigger signal is sent to the alarm module. The alarm module will issue an alarm prompt through the alarm device and feed back the alarm information to the data storage management module for storage. The data storage management module will display the calculation results and alarm information on the touch screen 21 for easy viewing by the staff. This device can not only realize continuous dynamic detection of cable bending radius, but also has a simple structure, effectively reducing costs. At the same time, it can also record the detection data of cable bending radius in real time, realizing accurate detection and real-time monitoring.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
