Description

Technical Field

[0001] The present invention relates to the technical field of underground cable protection devices, in particular to an underground cable anti-external damage monitoring device. Background Art

[0002] Underground cable: Underground cable refers to a cable that is often buried underground compared to common overhead lines, so it is also called underground cable. Cables are made of one or more mutually insulated conductors covered with an insulating layer and a protective layer, and are used to transmit electricity or information from one place to another. After entering modern society, due to the shortage of urban land, heavy traffic pressure, urban appearance construction and other reasons, large cities generally adopt underground cable transmission methods. Compared with overhead lines, cables have the advantages of small footprint, reliable power transmission, and strong anti-interference ability. The construction plan, protective measures, survey procedures, basic requirements for direct buried cables and underground cable fault locators of underground cables are introduced in detail. The existing technology has the following problems when protecting underground cables:

[0003] 1. At present, some technologies for protecting underground cables mostly directly set up signboards on the ground above the underground cables to protect the underground cables. However, when urban infrastructure equipment is excavated, it is impossible to quickly respond to the alarm, resulting in poor protection of the underground cables.

[0004] 2. When fixing cables inside underground pipe corridors, existing technologies mostly use clamps to lock and fix the cables inside the underground pipe corridors. Since the installation process is relatively complicated, the fixing of the cables is relatively inconvenient and the fixing operation time of the cables is relatively long. In response to the above problems, the inventors proposed an underground cable anti-external damage monitoring device to solve the above problems. Summary of the Invention

[0005] In order to solve the problems of poor anti-destruction effect of underground cables and inconvenient fixation of underground cables, the purpose of the present invention is to provide an underground cable anti-external damage monitoring device.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: an underground cable anti-external breakage monitoring device, comprising a pipe gallery, the outer wall of the pipe gallery is fixedly installed with evenly distributed conical plug rods, the outer wall of the conical plug rods is fixedly installed with evenly distributed reinforcing ribs, the inner wall of the pipe gallery is fixedly installed with a U-shaped frame plate, the lower surface of the U-shaped frame plate is provided with a movable seat, the side of the movable seat away from the U-shaped frame plate is fixedly installed with a base plate, the side of the base plate away from the movable seat is detachably installed with a vibration monitor, the surface of the U-shaped frame plate is provided with a patrol monitoring mechanism for the vibration monitor, the surface of the base plate is provided with a disassembly and assembly mechanism for the vibration monitor, and the interior of the pipe gallery is provided with a limiting mechanism.

[0007] The cam is fixedly provided with two guide rails, and the inner wall of the U-shaped frame plate is provided with two first guide grooves, and the inner walls of the two first guide grooves are slidably connected to the first guide blocks, and the lower surfaces of the two first guide blocks are fixedly connected to the upper surface of the moving seat.

[0008] Preferably, the disassembly and assembly mechanism includes two L-shaped fixing plates, the inner walls of the two L-shaped fixing plates are fixedly installed with L-shaped protective pads, the inner walls of the two L-shaped protective pads are in movably contact with the outer wall of the vibration monitor, a second guide groove is provided on the side of the base plate away from the movable seat, the inner wall of the second guide groove is slidably connected to two second guide blocks, the lower surface of one second guide block is fixedly connected to the upper surface of the L-shaped fixing plate, a double-headed screw is rotatably installed on one side of the base plate, the double-headed screw passes through the second guide groove and is threadably connected to the two second guide blocks, and a handle is fixedly installed on one end of the double-headed screw.

[0009] Preferably, the limiting mechanism includes a limiting sleeve, two support rods are fixedly installed on the outer wall of the limiting sleeve, one end of the support rod away from the limiting sleeve is fixedly connected to the inner wall of the pipe gallery, the inner wall of the limiting sleeve is provided with two curved limiting plates, and the inner wall of the curved limiting plate is fixedly installed with a curved insulating pad.

[0010] Preferably, the inner wall of the limiting sleeve is fixedly installed with a uniformly distributed base, the surface of the base is fixedly installed with a telescopic rod, the outer wall of the arc-shaped limiting plate is fixedly installed with a uniformly distributed connecting plate, the piston end of the telescopic rod is fixedly connected to the connecting plate, the outer wall of the telescopic rod is movably sleeved with a telescopic spring, one end of the telescopic spring is fixedly connected to the base, and the end of the telescopic spring away from the base is fixedly connected to the connecting plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The cable to be fixed is passed through the limiting sleeve. A telescopic rod and a telescopic spring are arranged inside the limiting sleeve. The extension of the telescopic rod and the telescopic spring causes the two arc-surface limiting plates and the two arc-surface insulating pads to always be close to each other through the connecting plate. The two arc-surface limiting plates and the two arc-surface insulating pads fix the cable passing through the limiting sleeve, thereby conveniently fixing the cable, thereby effectively improving the convenience of fixing the cable, and at the same time, saving a lot of working time for fixing the cable;

[0013] 2. The transmission is carried out by driving the transmission belt. The transmission belt drives the driving rod to move back and forth through the moving block.

When the vibration monitor moves back and forth, when the pipe corridor is damaged by external force and causes vibration, the vibration monitor detects the vibration information and transmits the vibration information, and sends out an alarm message at the same time, thereby conveniently realizing the anti-destruction protection of the cable line, thereby effectively improving the anti-destruction protection effect of the cable line, and at the same time, avoiding damage to the cable line due to urban infrastructure excavation;

[0014] 3. By rotating the double-headed screw, the double-headed screw causes the two second guide blocks to slide in reverse along the inner wall of the second guide groove. The two second guide blocks separate the two L-shaped fixing plates and the two L-shaped protective pads in reverse. Then, the vibration monitor can be taken out from between the two L-shaped fixing plates to realize the disassembly of the vibration monitor, thereby facilitating the disassembly of the vibration monitor and effectively improving the convenience of the staff in maintaining the vibration monitor.

[0032] The patrol monitoring mechanism 2 includes two rotating rods 21, which pass through the U-shaped frame plate 13 and are rotatably connected to the U-shaped frame plate 13. One end of the two rotating rods 21 is fixedly installed with a transmission wheel 22, and a transmission belt 23 is connected between the two transmission wheels 22.

[0040] The disassembly and assembly mechanism 4 includes two L-shaped fixing plates 41, and the inner walls of the two L-shaped fixing plates 41 are fixedly installed with L-shaped protective pads 42. The inner walls of the two L-shaped protective pads 42 are in movable contact with the outer wall of the vibration monitor 16. When the two L-shaped fixing plates 41 are close to each other, the two L-shaped fixing plates 41 can fix the vibration monitor 16 through the two L-shaped protective pads 42. The L-shaped protective pads 42 can protect the outer shell of the vibration monitor 16 to prevent the outer shell of the vibration monitor 16 from being worn.

[0042] A second guide groove 43 is provided on one side of the base plate 15 away from the movable seat 14, and two second guide blocks 44 are slidably connected to the inner wall of the second guide groove 43. The second guide blocks 44 can slide horizontally along the inner wall of the second guide groove 43.

A handle 46 is fixedly installed at one end of the double-headed screw 45. By turning the knob handle 46, the handle 46 can rotate the double-headed screw 45.

[0043] By adopting the above technical solution, the knob handle 46 is used to rotate the double-headed screw 45, and the double-headed screw 45 drives the two second guide blocks 44 to slide toward or away from each other along the inner wall of the second guide groove 43, and the second guide blocks 44 cause the L-shaped fixing plate 41 to move horizontally.

[0044] The limiting mechanism 5 includes a limiting sleeve 51. When the cable needs to be installed, the cable is passed through the limiting sleeve 51. Two support rods 52 are fixedly installed on the outer wall of the limiting sleeve 51. The end of the support rod 52 away from the limiting sleeve 51 is fixedly connected to the inner wall of the pipe gallery 1. The support rod 52 can support and fix the limiting sleeve 51. The inner wall of the limiting sleeve 51 is provided with two curved limiting plates 53. The inner wall of the curved limiting plate 53 is fixedly installed with a curved insulating pad 54. The two curved limiting plates 53 can limit the cable passing through the limiting sleeve 51 through the two curved insulating pads 54, thereby realizing the fixation of the cable and improving the convenience of fixing the cable.

[0045] By adopting the above technical solution, a support rod 52 is set up, and the support rod 52 supports and fixes the limiting sleeve 51. When the cable needs to be installed, the cable is passed through the limiting sleeve 51. The two arc-surface limiting plates 53 limit the cable passing through the limiting sleeve 51 through two arc-surface insulating pads 54, thereby realizing the fixation of the cable and improving the convenience of fixing the cable.

[0046] The inner wall of the limiting sleeve 51 is fixedly installed with an evenly distributed base 55, and the surface of the base 55 is fixedly installed with a telescopic rod 56. The outer wall of the arc limit plate 53 is fixedly installed with an evenly distributed connecting plate 58. The piston end of the telescopic rod 56 is fixedly connected to the connecting plate 58. The outer wall of the telescopic rod 56 is movably sleeved with a telescopic spring 57. One end of the telescopic spring 57 is fixedly connected to the base 55, and the end of the telescopic spring 57 away from the base 55 is fixedly connected to the connecting plate 58. By arranging the telescopic rod 56 and the telescopic spring 57, the extension of the telescopic rod 56 and the telescopic spring 57 makes the two arc limit plates 53 and the two arc insulating pads 54 always close to each other through the connecting plate 58, so that the two arc limit plates 53 and the two arc insulating pads 54 fix the cable passing through the limiting sleeve 51.

[0047] By adopting the above technical solution, by setting up a telescopic rod 56 and a telescopic spring 57, the extension of the telescopic rod 56 and the telescopic spring 57 allows the two arc-surface limit plates 53 and the two arc-surface insulating pads 54 to always be close to each other through the connecting plate 58, so that the two arc-surface limit plates 53 and the two arc-surface insulating pads 54 can fix the cable passing through the limiting sleeve 51.

[0048] Working principle: When it is necessary to fix the cables, the staff first makes the multiple cables to be fixed pass through the interior of the multiple limiting sleeves 51 one by one. By arranging multiple telescopic rods 56 and multiple telescopic springs 57 inside the limiting sleeves 51, the multiple telescopic rods 56 and multiple telescopic springs 57 are extended through the corresponding connecting plates 58 to make the two arc-surface limiting plates 53 and the two arc-surface insulating pads 54 always close to each other. The two arc-surface limiting plates 53 and the two arc-surface insulating pads 54 fix the cables passing through the limiting sleeves 51, thereby conveniently achieving the fixation of the cables, thereby effectively improving the convenience of fixing the cables, and at the same time, saving a lot of working time for fixing the cables;

[0049] By turning on the servo motor 27, the driving shaft of the servo motor 27 causes the corresponding rotating rod 21 to rotate. At this time, the two rotating rods 21 transmit the transmission belt 23 through the two transmission wheels 22. The transmission belt 23 causes the driving rod 25 to move back and forth horizontally through the moving block 24. The driving rod 25 causes the moving seat 14 to move back and forth horizontally through the strip groove 26. The moving seat 14 causes the two first guide blocks 3 to slide back and forth horizontally along the inner walls of the two first guide grooves 29 and causes the vibration monitor 16 to move back and forth horizontally through the base plate 15. While the vibration monitor 16 moves back and forth horizontally, when the pipe gallery 1 is damaged by external force and causes vibration, the vibration monitor 16 detects the vibration information and transmits the vibration information, and at the same time issues an alarm message, thereby conveniently realizing the anti-destruction protection of the cable line, thereby effectively improving the anti-destruction protection effect of the cable line, and at the same time, avoiding damage to the cable line due to urban infrastructure excavation;

[0050] When it is necessary to maintain the vibration monitor 16, the staff turns the knob handle 46, and the handle 46 rotates the double-headed screw 45. While the double-headed screw 45 rotates, the two second guide blocks 44 slide backward along the inner wall of the second guide groove 43. The two second guide blocks 44 separate the two L-shaped fixing plates 41 and the two L-shaped protective pads 42 in their backward directions. Then, the vibration monitor 16 can be taken out from between the two L-shaped fixing plates 41 to realize the disassembly of the vibration monitor 16, thereby facilitating the disassembly of the vibration monitor 16 and effectively improving the convenience of the staff in maintaining the vibration monitor 16.

[0051] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
