Description

Technical Field

[0001] The present invention relates to the technical field of cable anti-theft, and in particular to a vibration monitoring anti-theft cable. Background Art

[0002] Cables are widely used in many aspects of life, such as power systems, information transmission and instrumentation systems. In the process of using cables in the field of power systems, extra attention should be paid to anti-theft. This is because the metal materials contained in the cables have certain value, and the cables in the field of power systems are generally placed outdoors. The theft of cables will bring serious economic losses and affect the normal life of users.

[0003] At present, existing cable theft prevention measures generally focus on strengthening post-event accountability to deter cable theft. Referring to the utility model patent with publication number CN217382328U, a highway cable theft prevention device is disclosed. The device can monitor abnormal vibrations of the cable in real time through an external connection. The sensor structure can automatically activate the device to record video when triggered by vibration, thereby preserving evidence of the theft process and achieving unmanned automatic monitoring.

[0004] However, more efficient post-event accountability can prevent cable theft to a certain extent, but the effect is not good, and the thieves' ability to compensate is limited. However, the economic losses caused by cable theft are very high and greatly affect the normal production and life of users. For this reason, the present invention provides a vibration monitoring anti-theft cable, which greatly increases the difficulty of cable theft and creates time for managers to stop the theft in time. Summary of the Invention

[0005] The object of the present invention is to provide a vibration monitoring anti-theft cable to solve the problems raised in the above background technology.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0008] The air layer includes an inner shell, a support ring block and a first outer shell. The support ring block is arranged between the inner shell and the first outer shell. The inner side surface of the inner shell is provided with a convex arc groove. The support ring block is provided with a through hole.

[0009] The non-Newtonian fluid layer includes a second outer shell, the inner side of the second outer shell is fixedly connected to a plurality of partition ring plates, the inner side of the second outer shell is provided with a plurality of through-tubes, and the non-Newtonian fluid layer is provided with no less than two filling ports;

[0010] An extrusion needle is provided inside the through tube, and the extrusion needle includes a needle head provided at the top end thereof, and the needle head is placed in the second filling layer;

[0011] A plurality of vibration springs are fixedly connected to the inner side surface of the first shell, and a vibration optical cable is fixedly connected to one end of the vibration spring away from the first shell, and the vibration optical cable passes through the through opening.

[0012] Preferably, the interior of the through-tube is hollow, the through-tube passes through the second shell, and the bottom end of the through-tube is in contact with the outer side surface of the first shell.

[0013] Preferably, the inner side wall of the filling port is provided with a thread, the filling port can be threadably connected to a plug, and the outer side wall of the plug is also provided with a thread.

[0014] Preferably, a plurality of the vibration springs are arranged at equal distances, and the arrangement direction is the extension direction of the first shell.

[0015] Preferably, the through tubes are arranged at equal distances around the central axis of the second shell and at equal distances in the extension direction of the second shell.

[0016] Preferably, the inner side surface of the partition ring plate is in contact with the outer side surface of the first shell.

[0017] Preferably, a seal is provided between the vibration optical cable and the through opening, and the vibration optical cable is close to the convex arc groove.

[0018] Preferably, the vibration optical cable is sleeved with a rubber ring at the through-hole, and the outer side of the rubber ring is clamped on the inner side of the through-hole.

[0019] Preferably, the first conductive wire, the second conductive wire and the third conductive wire are arranged at equal distances around the central axis of the air layer inside the air layer.

[0021] Beneficial effects of the present invention: The present invention utilizes the property that the greater the pressure a non-Newtonian fluid is subjected to, the stronger its pressure resistance is, through the provision of a non-Newtonian fluid layer, so that the second shell is not easily compressed or damaged. At the same time, due to the provision of the air layer, not only does the non-Newtonian fluid layer below the second filling layer become thicker under the extrusion of the extrusion needle, but it also makes it more difficult for external damage to break through the non-Newtonian fluid layer. In this process, since the vibrating optical cable is fixed to the first shell by a vibrating spring, the vibration generated during the theft is transmitted to the vibrating optical cable. Since there are no obstacles on all sides, the vibration signal of the vibrating optical cable will be amplified under the action of the vibrating spring, thereby prompting the staff to discover the abnormality in time and stop it in time to avoid further damage to the cable, thereby greatly improving the anti-theft performance of the cable.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] Reference Figure 1-9 As shown, the present invention is a vibration monitoring anti-theft cable, including an air layer 3, a first conductor 1, a second conductor 101 and a third conductor 102 are arranged inside the air layer 3, the air layer 3 is filled with a first filling layer 2, a non-Newtonian fluid layer 4 is arranged outside the air layer 3, a second filling layer 5 is arranged outside the non-Newtonian fluid layer 4, and an external insulating layer 6 is arranged outside the second filling layer 5.

[0035] Furthermore, the air layer 3 includes an inner shell 301, a support ring block 302 and a first outer shell 305. The support ring block 302 is arranged between the inner shell 301 and the first outer shell 305. The inner side surface of the inner shell 301 is provided with a convex arc groove 304, and the support ring block 302 is provided with a through-hole 303. It should be supplemented that the setting of the convex arc groove 304 increases the vibration space of the vibrating optical cable 8, thereby avoiding the vibrating optical cable 8 being stuck when the cable is compressed and bent, thereby affecting its full vibration.

[0036] Furthermore, the non-Newtonian fluid layer 4 includes a second outer shell 401, and a plurality of partition plates 402 are fixedly connected to the inner side surface of the second outer shell 401. A plurality of through-tubes 403 are provided on the inner side surface of the second outer shell 401. There are no less than two filling ports 404 on the non-Newtonian fluid layer 4. It should be noted that the space between the second outer shell 401 and the first outer shell 305 is filled with non-Newtonian fluid, and the non-Newtonian fluid is filled through the filling port 404.

[0037] Furthermore, an extrusion needle 9 is provided inside the through-tube 403, and the extrusion needle 9 includes a needle head 901 arranged at its top end, and the needle head 901 is placed in the second filling layer 5. A plurality of vibration springs 7 are fixedly connected to the inner side surface of the first shell 305, and a vibration optical cable 8 is fixedly connected to the end of the vibration spring 7 away from the first shell 305, and the vibration optical cable 8 passes through the through-hole 303.

[0038] Among them, it should be supplemented that the interior of the through-tube 403 is hollow, the through-tube 403 passes through the second shell 401, the bottom end of the through-tube 403 is in contact with the outer side of the first shell 305, the inner side wall of the canning port 404 is provided with a thread, the canning port 404 can be threadedly connected to a plug 405, the outer side wall of the plug 405 is also provided with a thread, a plurality of vibration springs 7 are arranged at equal distances, and the arrangement direction is the extension direction of the first shell 305, the through-tube 403 is arranged at equal distances around the central axis of the second shell 401, and in the second shell The outer side of the rubber ring 403 is clamped on the inner side of the through-hole 303. Through such an arrangement, the local vibration of the vibration cable 8 is transmitted to the surrounding area at a lower degree, which is convenient for the staff to further accurately determine the vibration position, thereby more timely discovering and stopping the theft of cables.

[0039] Among them, it should be supplemented that the first wire 1, the second wire 101 and the third wire 102 are arranged at equal distances around the central axis of the air layer 3 inside the air layer 3. Through such an arrangement, the first wire 1, the second wire 101 and the third wire 102 can dissipate heat evenly, avoiding the local temperature inside the first filling layer 2 being too high due to two of the wires being close to each other, thereby affecting the heat dissipation. The second filling layer 5 is covered on the outer side of the second shell 401, and the external insulating layer 6 is covered on the outer side of the second filling layer 5.

[0040] The working principle of the cable is now explained through its working process: when the cable is being stolen, that is, when it is cut, the outer insulation layer 6 and the second filling layer 5 will be destroyed first. As the second filling layer 5 continues to be squeezed, the second shell 401 is also squeezed. Due to the setting of the non-Newtonian fluid layer 4, that is, the second shell 401 and the first shell 305 are filled with non-Newtonian fluid, the non-Newtonian compressive resistance becomes stronger as the pressure increases, making the second shell 401 not easily compressed or destroyed.

[0041] During this process, the needle 901 is squeezed by the second filling layer 5, causing the extrusion needle 9 to move toward the air layer 3. Since the interior of the through-tube 403 is hollow, the extrusion needle 9 does not need to pass through the non-Newtonian fluid. The extrusion needle 9 passes through the through-tube 403 to squeeze the first shell 305, causing the surface of the first shell 305 to be concave. Since the air layer 3 is squeezed, it begins to flatten, and then the non-Newtonian fluid filled between the second filling layer 5 is pushed to the concave part of the first shell 305, so that the non-Newtonian fluid layer 4 below the second filling layer 5 will be thicker, making the non-Newtonian fluid layer 4 more difficult to be destroyed, greatly increasing the difficulty of cutting the cable.

[0042] During this process, due to the setting of the air layer 3 and the vibration optical cable 8 being fixed to the first shell 305 by the vibration spring 7, the vibration generated during the theft of the cable is transmitted to the vibration optical cable 8. Since there are no obstacles or restrictions on its four sides, and under the action of the vibration spring 7, the vibration of the vibration optical cable 8 at this location is greatly amplified, and then the vibration signal monitored by the vibration optical cable 8 is amplified, making it easy for staff to detect abnormal vibrations, and then rush to the theft site in time to stop it, avoiding further damage to the cable, and greatly improving the anti-theft performance of the cable.

[0043] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
