Description

Technical Field

[0001] The 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, the existing cable theft prevention measures are generally to strengthen post-event accountability, so as to deter cable theft. Referring to the utility model patent with publication number CN217382328U, a highway cable theft prevention device is disclosed, which can monitor abnormal vibration of the cable in real time through external connection. The structure of the sensor can automatically activate the device to record the video when it is triggered by vibration, so as to preserve evidence of the theft process, thereby achieving the effect of 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 thief's 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 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, wherein the support ring block is arranged between the inner shell and the first outer shell, a convex arc groove is arranged on the inner side surface of the inner shell, and a through hole is opened on the support ring block;

[0009] The non-Newtonian fluid layer includes a second outer shell, a plurality of partition ring plates are fixedly connected to the inner side of the second outer shell, a plurality of through-thin tubes are arranged on the inner side of the second outer shell, and at least two filling ports are provided on the non-Newtonian fluid 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 threads, the filling port can be threadedly connected with a plug, and the outer side wall of the plug is also provided with threads.

[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 are arranged 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-hole, 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 inside the air layer around the central axis of the air layer.

[0020] Preferably, the second filling layer is coated on the outer side of the second shell, and the outer insulating layer is coated on the outer side of the second filling 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 outer shell is not easily compressed or damaged. At the same time, due to the provision of the air layer, not only the non-Newtonian fluid layer below the second filling layer is made 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 outer shell by a vibrating spring, the vibration generated during the theft process 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 promptly discover the abnormality 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 be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are 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 vibration optical cable 8, thereby preventing the vibration optical cable 8 from 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 ring plates 402 are fixedly connected to the inner side surface of the second outer shell 401. A plurality of through-tubes 403 are arranged on the inner side surface of the second outer shell 401. No less than two filling ports 404 are provided on the non-Newtonian fluid layer 4. It should be additionally 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 arranged inside the through-tube 403, and the extrusion needle 9 includes a needle head 901 arranged at the top end thereof, 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 one 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] It should be noted that the through-tube 403 is hollow inside, penetrates the second shell 401, and the bottom end of the through-tube 403 fits the outer side of the first shell 305. The inner wall of the canning port 404 is provided with a thread, and the canning port 404 can be threadedly connected with a plug 405, and the outer 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 305, the through-tube 403 is arranged at equal distances. The first and second shells 301 are arranged at equal distances in the extension direction of the shell 401, the inner side surface of the partition ring plate 402 is fitted with the outer side surface of the first shell 305, the vibration optical cable 8 and the through-hole 303 are sealed, and the vibration optical cable 8 is close to the convex arc groove 304, wherein the vibration optical cable 8 is located at the through-hole 303 and is sleeved with a rubber ring, and the outer side of the rubber ring is clamped on the inner side of the through-hole 303. Through such an arrangement, the local vibration of the vibration optical 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 behavior of stealing 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 coated on the outer side of the second shell 401, and the external insulating layer 6 is coated 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 insulating layer 6 and the second filling layer 5 will be destroyed first, and as the second filling layer 5 is continuously squeezed, the second outer shell 401 is also squeezed. Due to the setting of the non-Newtonian fluid layer 4, that is, the second outer shell 401 and the first outer shell 305 are filled with non-Newtonian fluid, the second outer shell 401 is not easily compressed or damaged because the non-Newtonian compressive resistance becomes stronger as the pressure increases.

[0041] During this process, the needle 901 is squeezed by the second filling layer 5, so that the extrusion needle 9 moves toward the air layer 3. Since the interior of the through capillary 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 capillary 403 to squeeze the first shell 305, causing the surface of the first shell 305 to become 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, which greatly increases the difficulty of cutting the cable.

[0042] In this process, due to the setting of the air layer 3 and the vibration optical cable 8 being fixed on the first shell 305 by the vibration spring 7, the vibration occurring during the theft of the cable is transmitted to the vibration optical cable 8. Since there are no obstacles or restrictions on its surroundings and under the action of the vibration spring 7, the vibration of the vibration optical cable 8 at this location is greatly amplified, thereby amplifying the vibration signal monitored by the vibration optical cable 8, making it easy for staff to detect abnormal vibrations and rush to the theft site in time to stop the theft, thus 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, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation 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.
