[0005] To address the aforementioned problems, this utility model provides an online cable monitoring device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an online cable monitoring device, comprising a protective box and a moving mechanism disposed on the protective box for driving the protective box to move, a lifting frame slidably disposed inside the protective box, a vertical rod fixed to the top of the lifting frame, a mounting frame rotatably mounted on the upper end of the vertical rod, an infrared detector fixed to the upper horizontal section of the mounting frame being disposed through the horizontal section, the detection end of the infrared detector being located between two sets of horizontal sections of the mounting frame, a connecting through hole being disposed through the top of the protective box for inserting and cooperating with the upper horizontal section of the mounting frame, a lifting mechanism for driving the lifting frame to rise and fall on the protective box, and a rotating mechanism for driving the mounting frame to rotate being disposed on the vertical rod and the mounting frame.

[0007] By adopting the above technical solution, when monitoring cables within the tunnel is required, a lifting mechanism drives the lifting frame upwards, causing the vertical rod connected to the lifting frame, the mounting bracket connected to the vertical rod, and the infrared detector connected to the mounting bracket to all rise until the monitoring end of the infrared detector is outside the protective box. At this point, the cables around the tunnel can be monitored. Simultaneously, the coordination of the lifting and rotating mechanisms allows for monitoring at multiple heights and angles. After the infrared detector has completed monitoring the cables around the tunnel, the lifting mechanism drives the lifting frame downwards and resets, causing the vertical rod, mounting bracket, and infrared detector to all descend and reset. At this point, the infrared detector is located inside the protective box, which protects it. This eliminates the interference issues associated with adjusting the height of the infrared detector found in existing technologies, ensuring the monitoring range of the camera.

[0008] Furthermore, the bottom of the lifting frame is provided with a threaded groove, and the lifting mechanism includes a lifting assembly. The lifting assembly includes a threaded rod rotatably mounted on the inner bottom wall of the protective box and threadedly connected to the threaded groove, a horizontal plate fixed on the lifting frame, and a sliding rod fixed between the inner bottom wall and the inner top wall of the protective box. The sliding rod passes through the horizontal plate and slides in fit. The lifting mechanism also includes a transmission assembly for driving the threaded rod to rotate.

[0009] By adopting the above technical solution, the threaded rod is driven to rotate by the transmission component. Due to the limiting of the horizontal plate by the slide bar, the threaded rod is threadedly connected to the lifting frame, thereby causing the lifting frame to drive the vertical rod to rise or fall, thus achieving the purpose of adjusting the height of the infrared detector.

[0010] Furthermore, the transmission assembly includes a fixed plate fixed to the bottom wall of the protective box, a transmission motor fixed to the fixed plate, a main synchronous pulley fixedly sleeved on the output end of the transmission motor, a driven synchronous pulley fixedly sleeved on the threaded rod, and a synchronous belt for connecting the driven synchronous pulley and the main synchronous pulley, wherein the synchronous belt meshes with both the main synchronous pulley and the driven synchronous pulley.

[0011] By adopting the above technical solution, the drive motor drives the main synchronous pulley to rotate after it starts working. Since the synchronous belt meshes with both the main and slave synchronous pulleys, the slave synchronous pulley and the threaded rod connected to it rotate, ensuring the normal lifting and lowering operation of the infrared detector.

[0012] Furthermore, the moving mechanism includes a moving component, which includes a mounting base fixed to the bottom of the protective box, a first rotating rod that passes through the mounting base and is rotatably connected to it, a second rotating rod that passes through the mounting base and is rotatably connected to it, two first moving wheels that are respectively fixed to both ends of the first rotating rod, and two second moving wheels that are respectively fixed to both ends of the second rotating rod. The moving mechanism also includes a drive component for driving the first rotating rod to rotate.

[0013] By adopting the above technical solution, the first rotating rod is driven to rotate by the driving component, which in turn causes the first moving wheel connected to the first rotating rod to rotate. Since the second rotating rod is rotated and mounted on the mounting base, and the second moving wheel is fixed on the second rotating rod, the purpose of moving the mounting base and the protective box as a whole can be achieved.

[0014] Furthermore, the drive assembly includes a drive motor fixed inside the protective box, a drive rod fixedly sleeved on the output end of the drive motor, a drive sprocket fixedly sleeved on the drive rod, a driven sprocket fixedly sleeved on the first rotating rod, and a chain for connecting the driven sprocket and the drive sprocket. The inner bottom of the protective box is provided with a rectangular through hole communicating with the inner bottom shell of the mounting base. The chain passes through the rectangular through hole, and the chain meshes with both the drive sprocket and the driven sprocket.

[0015] By adopting the above technical solution, after the installation of the bottom shell, the drive rod is driven to rotate, so that the driving sprocket connected to the drive rod, the chain meshing with the driving sprocket, the driven sprocket meshing with the chain, and the first rotating rod connected to the driven sprocket all rotate, ensuring the purpose of moving the entire device.

[0016] Furthermore, a through hole is provided on the side wall of the protective box, an air intake pipe is fixed in the through hole, and a fan blade located inside the air intake pipe is fixedly sleeved on the drive rod.

[0017] By adopting the above technical solution, during the rotation of the drive rod, the fan blades connected to the drive rod rotate. When the horizontal section of the mounting bracket is separated from the connecting through hole, the outside air is discharged into the protective box through the air intake pipe, and then discharged into the protective box through the connecting through hole, which has a heat dissipation effect on the components inside the protective box.

[0018] Furthermore, a dustproof plate is internally threaded into the mounting through hole, and the side wall of the dustproof plate near the air intake pipe is in contact with the air intake pipe.

[0019] By adopting the above technical solution and installing the dustproof panel, the probability of dust entering the protective box is reduced.

[0020] Furthermore, the horizontal sections on both the upper and lower sides of the mounting bracket are provided with multiple filter holes.

[0021] By adopting the above technical solution, when the horizontal section of the mounting bracket is connected to the connecting through hole, the hot air inside the protective box will be discharged through the filter hole, ensuring normal heat dissipation of the device.

[0022] Furthermore, the rotating mechanism includes a rotating motor fixed on the horizontal section below the mounting bracket, a drive gear fixedly sleeved on the output end of the rotating motor, and a driven gear fixedly sleeved on the vertical rod and meshing with the drive gear.

[0023] By adopting the above technical solution, the rotating motor drives the drive gear to rotate after it starts working. Since the mounting bracket is rotated and installed at the upper end of the vertical rod, the mounting bracket fixed to the rotating motor rotates, thus achieving the purpose of monitoring multiple angles with the infrared detector.

[0024] In summary, this utility model has the following beneficial effects: In this application, by setting up a lifting frame, a vertical rod, a mounting frame, a connecting through hole, and a lifting mechanism, the interference of the existing technology in the height adjustment of the infrared detector is eliminated, thus ensuring the monitoring range of the camera.

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] like Figure 1-5 As shown in the figure, this application discloses an online cable monitoring device, including a protective box 1, a lifting mechanism 8, a moving mechanism 2, and a rotating mechanism 9. A lifting frame 3 is slidably disposed inside the protective box 1. A threaded groove is formed at the bottom of the lifting frame 3, and a vertical rod 4 is fixed to the top of the lifting frame 3. A mounting bracket 5 is rotatably mounted on the upper end of the vertical rod 4. An infrared detector 6, fixed to the upper horizontal section of the mounting bracket 5, is disposed through the upper horizontal section of the mounting bracket 5. The detection end of the infrared detector 6 is located between the two sets of horizontal sections of the mounting bracket 5. A connecting through hole 7 is disposed through the top of the protective box 1, which is inserted and mated with the upper horizontal section of the mounting bracket 5.

[0033] When monitoring of cables within the tunnel is required, the lifting mechanism 8 drives the lifting frame 3 to rise, causing the vertical rod 4 connected to the lifting frame 3, the mounting frame 5 connected to the vertical rod 4, and the infrared detector 6 connected to the mounting frame 5 to all rise until the monitoring end of the infrared detector 6 is outside the protective box 1. At this point, the cables around the tunnel can be monitored. Simultaneously, the cooperation of the lifting mechanism 8 and the rotating mechanism 9 allows for monitoring at multiple heights and angles. After the infrared detector 6 has completed monitoring of the cables around the tunnel, the lifting mechanism 8 drives the lifting frame 3 to descend and reset, causing the vertical rod 4, the mounting frame 5, and the infrared detector 6 to all descend and reset. At this point, the infrared detector 6 is located inside the protective box 1, which protects the infrared detector 6 and eliminates the interference issues associated with adjusting the height of the infrared detector 6 found in existing technologies, thus ensuring the monitoring range of the camera.

[0034] A lifting mechanism 8 is mounted on the protective box 1 and is used to drive the lifting frame 3 to rise and fall. The lifting assembly 81 includes a threaded rod 811, a cross plate 812, and a sliding rod 813. The threaded rod 811 is rotatably mounted on the inner bottom wall of the protective box 1 and threadedly connected to the threaded groove. The sliding rod 813 is fixed to the cross plate 812 on the lifting frame 3 and fixed between the inner bottom wall and the inner top wall of the protective box 1. The sliding rod 813 passes through the cross plate 812 and slides in engagement with it.

[0035] The transmission assembly 82 drives the threaded rod 811 to rotate. The transmission assembly 82 includes a fixed plate 821, a drive motor 822, a main synchronous pulley 823, a driven synchronous pulley 824, and a synchronous belt 825. The fixed plate 821 is fixed to the inner bottom wall of the protective box 1, and the drive motor 822 is fixed to the fixed plate 821. The main synchronous pulley 823 is fixedly sleeved on the output end of the drive motor 822, and the driven synchronous pulley 824 is fixedly sleeved on the threaded rod 811. The synchronous belt 825 connects the driven synchronous pulley 824 and the main synchronous pulley 823, and the synchronous belt 825 meshes with both the main synchronous pulley 823 and the driven synchronous pulley 824.

[0036] After the drive motor 822 starts working, it drives the main synchronous pulley 823 to rotate. Since the synchronous belt 825 is engaged with both the main synchronous pulley 823 and the driven synchronous pulley 824, the driven synchronous pulley 824 and the threaded rod 811 connected to the driven synchronous pulley 824 rotate. Due to the limiting of the horizontal plate 812 by the slide rod 813, the threaded rod 811 is threadedly connected to the lifting frame 3, thereby causing the lifting frame 3 to drive the vertical rod 4 to rise or fall, so as to achieve the purpose of adjusting the height of the infrared detector 6.

[0037] A moving mechanism 2 is mounted on the protective case 1 and is used to drive the protective case 1 to move. The moving mechanism 2 includes a moving component 21 and a driving component 22. The moving component 21 includes a mounting base 211, a first rotating rod 212, a second rotating rod 213, a first moving wheel 214, and a second moving wheel 215. The mounting base 211 is fixed to the bottom of the protective case 1. The first rotating rod 212 passes through the mounting base 211 and is rotatably connected. The second rotating rod 213 passes through the mounting base 211 and is rotatably connected. The first moving wheel 214 is fixed to the first rotating rod 212, and two of the first moving wheels 214 are respectively located at both ends of the first rotating rod 212. The second moving wheel 215 is fixed to the second rotating rod 213, and two sets of the second moving wheels 215 are respectively fixed at both ends of the second rotating rod 213.

[0038] The drive assembly 22 is used to drive the first rotating rod 212 to rotate. The drive assembly 22 includes a drive motor 221, a drive rod 222, a drive sprocket 223, a driven sprocket 224, and a chain 225. The drive motor 221 is fixed inside the protective housing 1, and the drive rod 222 is fixedly sleeved on the output end of the drive motor 221. The drive sprocket 223 is fixedly sleeved on the drive rod 222, and the driven sprocket 224 is fixedly sleeved on the first rotating rod 212. The chain 225 is used to connect the driven sprocket 224 and the drive sprocket 223, and the chain 225 meshes with both the drive sprocket 223 and the driven sprocket 224. A rectangular through hole 226 communicating with the inside of the mounting base 211 is provided through the inner bottom of the protective housing 1, and the chain 225 passes through the rectangular through hole 226. After the mounting base 211 is in operation, it drives the drive rod 222 to rotate, causing the drive sprocket 223 connected to the drive rod 222, the chain 225 meshing with the drive sprocket 223, the driven sprocket 224 meshing with the chain 225, the first rotating rod 212 connected to the driven sprocket 224, and the first moving wheel 214 connected to the first rotating rod 212 to all rotate. Since the second rotating rod 213 is rotatably mounted on the mounting base 211 and the second moving wheel 215 is fixed on the second rotating rod 213, the purpose of moving the mounting base 211 and the protective box 1 as a whole can be achieved.

[0039] A mounting through hole 10 is provided through the side wall of the protective box 1. An air intake pipe 11 is fixed inside the mounting through hole 10, and a fan blade 12 located inside the air intake pipe 11 is fixedly sleeved on the drive rod 222. During the rotation of the drive rod 222, the fan blade 12 connected to the drive rod 222 rotates. When the horizontal section of the mounting frame 5 is separated from the connecting through hole 7, the outside air is discharged into the protective box 1 through the air intake pipe 11, and then discharged into the protective box 1 through the connecting through hole 7, which has a heat dissipation effect on the components inside the protective box 1.

[0040] A dustproof plate 13 is internally threaded into the mounting hole 10, and the side wall of the dustproof plate 13 near the air intake pipe 11 is in contact with the air intake pipe 11. The dustproof plate 13 reduces the probability of dust entering the protective box 1.

[0041] Multiple filter holes are provided through the horizontal sections on both the upper and lower sides of the mounting bracket 5. When the horizontal section of the mounting bracket 5 is connected to the connecting through hole 7, hot air inside the protective box 1 will be discharged through the filter holes, ensuring normal heat dissipation of the device.

[0042] The rotating mechanism 9 is mounted on both the vertical rod 4 and the mounting bracket 5. The rotating mechanism 9 includes a rotating motor 91, a driving gear 92, and a driven gear 93. The rotating motor 91 is fixed to the horizontal section below the mounting bracket 5. The driving gear 92 is fixedly sleeved on the output end of the rotating motor 91. The driven gear 93 is fixedly sleeved on the vertical rod 4 and meshes with the driving gear 92. When the rotating motor 91 operates, it drives the driving gear 92 to rotate. Since the mounting bracket 5 is rotatably mounted on the upper end of the vertical rod 4, the mounting bracket 5, which is fixed to the rotating motor 91, rotates, thus achieving the purpose of multi-angle monitoring by the infrared detector 6.
