Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical cable monitoring technology, and in particular to a monitoring device for preventing external damage to optical cables. Background Technology
[0002] Underground installation has become the mainstream method for laying optical cables and electrical cables. Traditional methods for monitoring optical cables and electrical cables mainly rely on manual, timed, and fixed-point inspections. However, in more remote locations, there are few inspectors, resulting in the failure to detect external forces that are damaging the cables in a timely manner. Existing research shows that vibrations in optical cables caused by external forces will cause changes in the optical signal. Therefore, by monitoring changes in the optical signal of the optical cable, the location of the current external force damage can be determined. As a result, various optical cable-based external force damage monitoring devices have begun to appear on the market.
[0003] Currently, the internal optoelectronic components of fiber optic cable-based anti-damage monitoring equipment typically include modules such as a laser emitter, a fiber optic cable detection device, a power supply, and a main control unit. Among these, the components constituting the laser emitter and fiber optic cable detection device are relatively delicate, making them susceptible to damage when the equipment is dropped or subjected to other external forces. Existing fiber optic cable-based anti-damage monitoring equipment has a relatively simple structure and lacks external protective features. This makes the internal precision components vulnerable to damage, and its poor shock resistance hinders the creation of a stable working environment, thus affecting detection accuracy. Utility Model Content
[0004] The present invention aims to overcome at least one of the defects of the prior art and provide a fiber optic cable-based monitoring device for preventing external damage, thereby solving the problem of poor protection.
[0005] To achieve the above objectives, the optical cable-based external force damage monitoring device of this utility model includes a base, a main housing, and a protective plate. The main housing is equipped with a laser emitting device, an optical cable detection device, and a power supply device. The laser emitting device and the optical cable detection device are both powered by the power supply device. The laser emitting device is connected to the optical cable detection device and is used to provide a laser light source for the optical cable detection device.
[0006] The main housing is connected to the top of the base via a first buffer mechanism. The bottom of the protective plate is provided with multiple buffer grooves around its perimeter. A second buffer mechanism is provided in each buffer groove and is movably connected to the main housing.
[0007] In this design, the base is connected to the bottom of the housing via a first buffer mechanism, which prevents the bottom of the fiber optic cable-based anti-external force monitoring device from making hard contact with the outside when it is dropped. The protective plate is connected to the top of the housing via a second buffer mechanism, which prevents external objects or forces from acting directly on the monitoring device from above. This protects the internal components such as the laser emitting device and the fiber optic cable detection device. Furthermore, the first and second buffer mechanisms enhance the vibration resistance of the device, thereby providing a stable working environment for the internal components and helping to improve monitoring accuracy.
[0008] In some embodiments, the first buffer mechanism includes a plurality of damping shock absorbers, both ends of which are respectively connected to the top of the base and the bottom of the main housing.
[0009] In some embodiments, the base is provided with multiple mounting slots for placing the damping shock absorber.
[0010] In some embodiments, the second buffer mechanism includes a slide rod, a slider, and an elastic element. The slide rod is arranged radially inside the buffer groove along the base. The slider is slidably sleeved on the slide rod. The two ends of the elastic element abut against the slider and the inner wall of the buffer groove, respectively. The slider is movably connected to the main housing through a transmission rod.
[0011] In this design, the elastic element always tends to push the slider against the inner wall of the buffer groove. Thus, when the protective plate moves towards the main housing under the action of external force, the elastic element can buffer the slider and prevent the transmission rod hinged to the slider from swinging excessively. As a result, the protective plate and the top of the main housing can always maintain a gap to prevent the main housing from making hard contact with the outside.
[0012] In some embodiments, the first end of the elastic element abuts against the slider, and the second end of the elastic element abuts against the inner wall of the buffer groove on the inner side.
[0013] In this solution, the second buffer mechanism can provide a buffering effect when the protective plate is subjected to external force in the horizontal direction, thus avoiding hard contact between the fiber optic cable-based anti-external force damage monitoring equipment and the device.
[0014] In other embodiments, the first end of the elastic element abuts against the inner wall of the buffer groove on the outer side, and the second end of the elastic element abuts against the slider.
[0015] In this design, the second buffer mechanism can provide a buffering effect when the protective plate is subjected to a vertical external force, thus preventing hard contact between the protective plate and the main shell.
[0016] In some embodiments, the elastic element is a spring sleeved on the slide rod, with both ends of the spring abutting against the inner walls of the slider and the buffer groove, respectively.
[0017] In some embodiments, the main housing is provided with an air inlet and an air outlet, and a cooling fan is provided inside the main housing to drive air from the air inlet to the air outlet.
[0018] In some embodiments, the air inlet is located at the top of the main housing, the protective plate has multiple air inlet holes at positions corresponding to the air inlet, and the air outlet is located at the bottom of the main housing.
[0019] In some embodiments, a controller is also provided inside the main housing, and the laser emitting device and the optical cable detection device are both electrically connected to the controller, which is electrically connected to the power supply device.
[0020] This solution facilitates the simultaneous operation of the laser emitting device and the optical cable detection device via a controller, thereby improving monitoring efficiency.
[0021] In some embodiments, a temperature sensor is also provided inside the main housing, and the temperature sensor is electrically connected to the controller.
[0022] Since ambient temperature affects the operating status of laser emitting devices and optical cable detection devices, this solution can use a controller to obtain temperature data and then adjust the laser emitting devices and optical cable detection devices to appropriate operating parameters.
[0023] In some embodiments, a communication module is also provided inside the main housing, and the communication module is electrically connected to the controller.
[0024] In some embodiments, a positioning module is also provided inside the main housing, and the positioning module is electrically connected to the controller.
[0025] This solution can obtain the current location information through the positioning module, which facilitates the acquisition of relevant optical cable information.
[0026] In some embodiments, the side of the main housing is provided with an installation port communicating with the interior of the main housing, and a baffle is rotatably connected inside the installation port.
[0027] Compared with the prior art, the present invention has the following beneficial effects:
[0028] In this invention, the main housing can be protected from at least two directions, top and bottom, by the first buffer mechanism and the base, and the second buffer mechanism and the protective plate, reducing the damage of external forces to the optical cable-based anti-external force monitoring device. Furthermore, the buffering effect of the first and second buffer mechanisms enhances the vibration resistance of the optical cable-based anti-external force monitoring device, providing a stable working environment for the laser emitting device and the optical cable detection device, thereby improving the monitoring accuracy.

Detailed Implementation
[0032] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this utility model. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions; it is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Clearly, the described embodiments are only a portion of the embodiments of this utility model, and not all of them.
[0033] Example 1
[0034] refer to Figure 1-2 This utility model discloses a monitoring device for preventing external damage based on optical cables, including a base 100, a main housing 200, and a protective plate 300. The main housing 200 is equipped with a laser emitting device 400, an optical cable detection device 500, and a power supply device 600. The laser emitting device 400 and the optical cable detection device 500 are both powered by the power supply device 600. The laser emitting device 400 is connected to the optical cable detection device 500 and is used to provide a laser light source for the optical cable detection device 500.
[0035] The top of the main housing 200 is connected to the base 100 via a first buffer mechanism 700. Multiple buffer grooves 310 are provided around the bottom of the protective plate 300, and a second buffer mechanism 800 is installed within each buffer groove 310. The second buffer mechanism 800 is movably connected to the main housing 200. In specific implementations, the laser emitting device 400, the optical cable detection device 500, and the power supply device 600 can be fixedly mounted inside the main housing 200 using a support frame, or they can be directly fixed to the inside of the main housing using bolts or other fasteners to achieve a stable connection with the housing.
[0036] In use, the base 100 is connected to the bottom of the housing via the first buffer mechanism 700, which prevents the bottom of the fiber optic cable-based anti-external force monitoring device from making hard contact with the outside when it is dropped. The protective plate 300 is connected to the top of the housing via the second buffer mechanism 800, which prevents external objects or forces from acting directly on the monitoring device from above. In this way, the laser emitting device 400, fiber optic cable detection device 500 and other internal components of the fiber optic cable-based anti-external force monitoring device can be protected. Furthermore, the first buffer mechanism 700 and the second buffer mechanism 800 can improve the vibration resistance of the fiber optic cable-based anti-external force monitoring device, thereby providing a stable working environment for the internal components and helping to improve monitoring accuracy.
[0037] The laser emitting device 400 may include a laser emitting device 400 and a mounting box, which is installed inside the main housing 200 and serves as the mounting box for the laser emitting device 400. The optical cable testing device 500 includes at least one of an OTDR (optical time domain reflectometer) module, a distributed acoustic sensing module, and a distributed vibration sensing module. The laser emitting device 400 provides a light source to the OTDR module, the distributed acoustic sensing module, or the distributed vibration sensing module. After processing, the OTDR module, the distributed acoustic sensing module, or the distributed vibration sensing module sends a laser beam to the optical cable under test and receives and analyzes the reflected light signal returned by the optical cable under test, thereby monitoring the optical cable under test. If the optical cable under test or its associated facilities (such as cables, nearby ground facilities, etc.) is damaged by external forces, it will cause changes in the optical signal. The operator can obtain the optical signal information through the optical cable detection device 500, and then promptly inspect the location through which the optical cable passes, so as to stop the external damage in time.
[0038] In addition, the optical cable detection device 500 also includes several optical cable interfaces 510, which are exposed on the surface of the main housing 200 through several first exposure ports provided on the main housing 200. The power supply device 600 can be implemented in the form of a built-in battery, power adapter, etc. In a specific implementation, a power interface 610 is also provided, which is exposed through a second exposure port provided on the surface of the main housing 200.
[0039] In specific implementation, the first buffer mechanism 700 includes multiple damping shock absorbers 710, with both ends of the damping shock absorber 710 connected to the top of the base 100 and the bottom of the main housing 200, respectively.
[0040] In practice, the base 100 is provided with multiple mounting slots 110 for placing the damping shock absorber 710, which can improve the connection strength between the damping shock absorber 710 and the base 100.
[0041] In specific implementation, the second buffer mechanism 800 includes a slide rod 810, a slider 820, and an elastic element 830. The slide rod 810 is arranged radially inside the buffer groove 310 along the base 100. The slider 820 is slidably sleeved on the slide rod 810. The two ends of the elastic element 830 abut against the slider 820 and the inner wall of the buffer groove 310, respectively. The slider 820 is movably connected to the main housing 200 through the transmission rod 840.
[0042] During operation, the elastic element 830 always maintains a tendency to push the slider 820 against the inner wall of the buffer groove 310. Therefore, when the protective plate 300 moves towards the main housing 200 under external force, the elastic element 830 can buffer the slider 820, preventing excessive swinging of the transmission rod 840 hinged to the slider 820. This ensures that a gap is always maintained between the protective plate 300 and the top of the main housing 200, preventing hard contact between the main housing 200 and the outside. The elastic element 830 is a spring sleeved on the slider 810, with both ends abutting against the slider 820 and the inner wall of the buffer groove 310, respectively.
[0043] refer to Figure 1 In some embodiments, the first end of the elastic element 830 abuts against the slider 820, and the second end of the elastic element 830 abuts against the inner wall of the buffer groove 310 located on the inner side. When the second buffer mechanism 800 is subjected to an external force in the horizontal direction, it can provide a buffering effect to avoid hard contact between the equipment.
[0044] In other embodiments, the first end of the elastic member 830 abuts against the inner wall of the buffer groove 310 on the outer side, and the second end of the elastic member 830 abuts against the slider 820. When the second buffer mechanism 800 is subjected to a vertical external force, it can provide a buffering effect to prevent the protective plate 300 from making hard contact with the main housing 200.
[0045] like Figure 1 As shown, the main housing 200 has an air inlet 210 and an air outlet 220. A cooling fan 230 is installed inside the main housing 200, driving air from the air inlet 210 to the air outlet 220. In a specific implementation, since the four sides of the main housing 200 need to accommodate various interfaces and mounting openings 240, the air inlet 210 is located at the top of the main housing 200, and the protective plate 300 has multiple air inlet holes 320 corresponding to the air inlet 210. The air outlet 220 is located at the bottom of the main housing 200. To prevent dust from entering the equipment, a first filter 211 and a second filter 221 are respectively installed on the air outlet 220 and the air inlet 210.
[0046] refer to Figure 1-2 To facilitate operation, a controller 900 is also installed inside the main housing 200. The laser emitting device 400 and the optical cable detection device 500 are both electrically connected to the controller 900, which is also electrically connected to the power supply device 600. The controller 900 can operate the laser emitting device 400 and the optical cable detection device 500, improving monitoring efficiency. The controller 900 is connected to a data interface 910, which is exposed on the side of the main housing 200 through a third exposure port.
[0047] refer to Figure 1-2 In some embodiments, a temperature sensor 250 is also provided inside the main housing 200. The temperature sensor 250 is electrically connected to the controller 900. It is understood that since the ambient temperature will affect the operating status of the laser emitting device 400 and the optical cable detection device 500, the temperature sensor 250 can obtain temperature data with the help of the controller 900, and then adjust the laser emitting device 400 and the optical cable detection device 500 to the appropriate operating parameters.
[0048] In a preferred embodiment, the cooling fan 230 is electrically connected to the controller 900. The controller 5 controls the start / stop or adjusts the power of the cooling fan 230 according to a preset temperature threshold. This reduces energy consumption and improves the performance of the fiber optic cable-based anti-external force damage monitoring equipment.
[0049] In some embodiments, a communication module 260 is also provided inside the main housing 200. The communication module 260 is electrically connected to the controller 900. Through the communication module 260, it is convenient for the fiber optic cable-based anti-external force damage monitoring equipment to import or export data with external devices, thereby improving work efficiency. In specific implementations, the communication module 260 can be implemented in the form of Wi-Fi, Bluetooth, 4G module, 5G module, etc.
[0050] In some embodiments, a positioning module 270 is also provided inside the main housing 200. The positioning module 270 is electrically connected to the controller 900. The positioning module can accurately obtain the current location information, which facilitates the retrieval of the corresponding optical cable information by the controller 900. In specific implementations, the positioning module can be a GPS navigation module or a Beidou navigation module.
[0051] refer to Figure 1 In some embodiments, one end of the main housing 200 is provided with an installation port 240 that communicates with the interior of the main housing 200. A baffle 241 is rotatably connected inside the installation port 240. Personnel can install, remove and repair the devices inside the fiber optic cable-based anti-external force damage monitoring equipment through the installation port 240. The baffle 241 can provide protection for the devices inside the main housing 200.
[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
