[0002] "Underground" mentioned in the power industry usually refers to underground environments, including but not limited to mines, tunnels, underground pipelines, subway systems, etc. In cities and industrial areas, the ground space may be very crowded and unable to accommodate more infrastructure. Therefore, cables and other facilities are often placed underground to utilize limited space. When underground cables are used, displacement monitoring devices are usually used to monitor the cables to prevent the cables from being displaced or twisted due to external forces, which may affect the structural integrity and functionality of the cables.

[0003] As shown in the reference case "An underground cable settlement displacement monitoring device" announcement number "CN218238808U", the head end of the traction line is fixed to the underground cable to be detected, and the end is linked to the displacement detection module; when the underground cable to be detected settles and displaces, the displacement of the head end of the traction line is transmitted to the end, and the displacement detection module detects the movement of the end of the traction line to detect the displacement of the underground cable to be detected, so that the cable settlement can be monitored in time;

[0004] Although the existing underground displacement monitoring devices can implement basic displacement monitoring functions, due to the vibration and impact generated by geological activities, heavy machinery operations and other industrial activities, the sensitive electronic components in the underground monitoring devices are easily damaged by vibration and impact, resulting in reduced data reading accuracy.

[0005] Therefore, a displacement monitoring device for downhole cable monitoring is proposed to solve the above problems. Utility Model Content

Their purpose is to ensure the stability and functionality of the cable, while preventing potential damage caused by position changes. When the underground displacement monitor 2 is in use, the protective component 32 can absorb or reduce the direct impact of external impact on the displacement monitor 2 when it vibrates underground, thereby protecting the monitoring accuracy and operation stability of the monitor, and the contact component 33 can be used to buffer the impact when the protective shell 31 is received to reduce the impact strength.

[0024] like Figure 2 and Figure 3As shown, the protection assembly 32 includes a first support block 321 fixedly mounted on both sides of the protection shell 31, a second support block 322 is arranged at the bottom of the two first support blocks 321, the two second support blocks 322 are fixedly connected to the fixing frame 1, a piston rod 323 is fixedly mounted on one side of the second support block 322, one end of the piston rod 323 is slidably connected to the adjacent first support block 321, a storage chamber 325 is provided inside the piston rod 323, the storage chamber 325 is connected to the inside of the first support block 321 through a flow hole 324, the activity space of the piston rod 323 inside the first support block 321 and the inside of the storage chamber 325 are both stored with hydraulic oil, when the protection shell 31 is vibrated, the two first support blocks 321 are synchronously driven to slide on the corresponding piston rod 323, through which The piston rod 323 pushes the hydraulic oil to flow in the active space in the first support block 321, and the hydraulic oil flows into or out of the storage chamber 325 of the piston rod 323 through the narrow flow hole 324, thereby producing a buffering effect, effectively absorbing and dispersing the impact energy caused by external vibration, and reducing the impact force directly transmitted to the displacement monitor 2, thereby protecting sensitive monitoring equipment from damage. The protection component 32 also includes a piston plate 326 slidably mounted inside the storage chamber 325, and a first spring 327 is fixedly mounted on one side of the piston plate 326, and the other end of the first spring 327 is fixedly connected to the inner wall of the storage chamber 325. When the hydraulic oil enters the storage chamber 325, the piston plate 326 is synchronously squeezed to move, and the movement of the piston plate 326 causes The hydraulic oil on the other side is compressed, and the first spring 327 is also compressed, which can absorb the kinetic energy caused by the vibration synchronously. When the vibration stops, the reset of the first spring 327 pushes the piston plate 326 back to the initial position, and the hydraulic oil also returns to its original position to release the stored energy. A buffer plate 328 is slidably installed inside the protective shell 31, and the buffer plate 328 is located above the displacement monitor 2. A plurality of support rods 3210 are fixedly installed on the inner top wall of the protective shell 31, and one end of the plurality of support rods 3210 passes through the buffer plate 328. A second spring 3211 is sleeved through the surface of the support rod 3210, and the second spring 3211 is located at the bottom of the buffer plate 328. The other end of the second spring 3211 is fixedly connected to the buffer plate 328. When the protective shell 31 moves downward, The internal buffer plate 328 is synchronously driven to move downward. At this time, the second spring 3211 is compressed, so that the buffer plate 328 can provide buffering through the second spring 3211 when subjected to a downward force, thereby absorbing and reducing the force transmitted to the displacement monitor 2 due to external impact or vibration. When the external force disappears, the elastic force of the second spring 3211 resets the buffer plate 328, so that it is ready to cope with the next impact. Multiple rubber plates 329 are fixedly installed on both sides of the buffer plate 328. The multiple rubber plates 329 are all set in an arc shape. When the buffer plate 328 moves, the rubber plates 329 are synchronously driven to move.

The top volume of the contact plate 333 gradually increases from bottom to top. When the protective shell 31 is in use, the contact plate 333 can be used to contact the object on the top. The gradually increasing contact plate 333 from bottom to top can increase the contact area, thereby increasing the contact area, improving the contact stability and dispersing the force. The contact component 33 also includes a movable plate 332 fixedly mounted on the bottom of the contact plate 333, which is slidably connected to the guide frame 331. A plurality of third springs 334 are fixedly mounted inside the guide frame 331, and the other ends of the plurality of third springs 334 are fixedly connected to the movable plate 332. When the contact plate 333 is impacted, the movable plate 332 can be synchronously moved to squeeze the plurality of third springs 334, so that the plurality of third springs 334 can buffer the impact, thereby reducing the impact and vibration damage.

[0026] When the utility model is in use, when the protective shell 31 is subjected to vibration, it synchronously drives the two first support blocks 321 to slide on the corresponding piston rods 323. Through this sliding, the piston rod 323 pushes the hydraulic oil to flow in the active space inside the first support block 321, and the hydraulic oil flows into or flows out of the storage chamber 325 of the piston rod 323 through the narrow flow hole 324, thereby producing a buffering effect, effectively absorbing and dispersing the impact energy caused by external vibration, and reducing the impact force directly transmitted to the displacement monitor 2, thereby protecting sensitive monitoring equipment from damage. When the hydraulic oil enters the storage chamber 325, it synchronously squeezes the piston plate 326 to move. The movement of the piston plate 326 causes the hydraulic oil on the other side to be compressed, and the first spring 327 is also compressed, which can synchronously absorb the kinetic energy caused by the vibration. When the vibration stops, the reset of the first spring 327 pushes the piston plate 326 back to the initial position, and the hydraulic oil also returns to its original position, releasing the stored energy. When the protective shell 31 moves downward, it synchronously drives the internal buffer plate 328 to move downward. At this time, the second The spring 3211 is compressed, so that the buffer plate 328 can provide buffering through the second spring 3211 when it is subjected to downward force, thereby absorbing and reducing the force transmitted to the displacement monitor 2 due to external impact or vibration. When the external force disappears, the elastic force of the second spring 3211 resets the buffer plate 328, so that it is ready to cope with the next impact. When the buffer plate 328 moves, the rubber plate 329 is simultaneously driven to move. The rubber plates 329 on both sides contact the displacement monitor 2 and the top wall of the protective shell 31. The rubber plate 329 provides additional buffering and shock absorption. The arc-shaped rubber plate 329 enables it to distribute pressure more smoothly during the contact process. When the protective shell 31 is in use, it can contact the object on the top through the contact plate 333. The contact plate 333 gradually increases from bottom to top, so that the contact area can be increased, thereby increasing the contact stability and dispersing the force. When the contact plate 333 is impacted, multiple third springs 334 are used to buffer the impact, thereby reducing impact and vibration damage.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
