[0029] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a cable anti-theft alarm device based on wireless sensing, comprising:

[0031] The clamping block 2 is fastened to the cable 1. The clamping block 2 is equipped with an anti-theft alarm mechanism. It should be noted that when the cable 1 is stolen, it can quickly and efficiently trigger an alarm.

[0032] The burglar alarm mechanism includes an assembly block 3, a steel rope 4, a placement tube 5, an inner frame 8, a movable plate 9, a disc 10, a magnetic induction sensor 12, a magnet 13, and a wireless magnetic induction alarm 15.

[0033] Assembly block 3 is fixedly connected to clamping block 2, steel rope 4 is fixedly connected to assembly block 3, and inner frame 8 is fixedly installed inside placement cylinder 5. It should be noted that placement cylinder 5 can be buried in shallow soil.

[0034] The movable plate 9 is vertically slidably installed on the inner frame 8. The movable plate 9 is fixedly connected to the disc 10. The magnetic induction sensor 12 is fixedly installed on the top of the inner frame 8. The magnet 13 is fixedly installed on the bottom of the disc 10. The magnetic induction sensor 12 and the magnet 13 are attracted to each other. The wireless magnetic induction alarm 15 is fixedly installed on the top of the disc 10.

[0035] With the above structure, the magnetic induction sensor 12 and the magnet 13 attract each other. When they are attracted, the wireless electromagnetic induction alarm 15 does not sound. When the cable 1 is stolen, the cable 1 will move the clamping block 2, which in turn will cause the assembly block 3 to move the steel rope 4. The steel rope 4 will move the disc 10, which will move the magnet 13, causing the magnet 13 to separate from the magnetic induction sensor 12. At this time, the wireless electromagnetic induction alarm 15 will sound, allowing the wireless electromagnetic induction alarm 15 to provide alarm reminders to staff through wireless transmission, enabling fast and efficient alarm handling.

[0036] Specifically, the burglar alarm mechanism also includes a base plate 11 and a spring 14. The base plate 11 is fixedly installed at the bottom of the movable plate 9, and the spring 14 is fixedly installed between the base plate 11 and the inner frame 8.

[0037] With the above structure, when the disk 10 moves upward, the moving plate 9 can drive the base plate 11 to move upward, thereby causing the base plate 11 to compress the spring 14.

[0038] Specifically, a threaded cap 7 is threaded onto the top of the outer side of the placement cylinder 5, and multiple stabilizing rods 16 are fixedly installed at the bottom of the placement cylinder 5. It should be noted that the stabilizing rods 16 can be inserted into the soil to improve the stability of the placement cylinder 5.

[0039] Specifically, assembly blocks 3 have assembly holes. It should be noted that the two assembly blocks 3 are locked and fixed by bolts.

[0040] Specifically, the top of the inner frame 8 has a movable hole, and the movable plate 9 is vertically slidably installed in the movable hole. It should be noted that this allows the movable plate 9 to move stably in the vertical direction.

[0041] Specifically, the placement cylinder 5 has a rope hole 6, the steel rope 4 is in contact with the inner wall of the rope hole 6, and a guide rod is fixedly installed inside the placement cylinder 5. The steel rope 4 is in contact with the outer side of the guide rod. It should be noted that the steel rope 4 can be guided.

[0042] Working principle:

[0043] S1: First, bury the placement cylinder 5 in shallow soil near the cable 1. Multiple stabilizing rods 16 fixed at the bottom of the placement cylinder 5 are inserted into the soil to improve the installation stability of the placement cylinder 5. Next, fasten the clamping block 2 onto the cable 1. Through the assembly holes on the assembly block 3, use bolts to lock and fix the two assembly blocks 3, ensuring a firm connection between the clamping block 2 and the cable 1. One end of the steel rope 4 is fixedly connected to the assembly block 3, and the other end passes through the rope hole 6 on the placement cylinder 5 and is associated with the disc 10. The guide rod inside the placement cylinder 5 guides the steel rope 4. To ensure smooth transmission of the steel rope 4, the magnetic induction sensor 12 at the top of the inner frame 8 and the magnet 13 at the bottom of the disc 10 attract each other. Under the action of gravity and attraction, the moving plate 9 is positioned at the top of the inner frame 8. The spring 14 between the bottom plate 11 and the inner frame 8 is in a naturally extended state. The wireless magnetic induction alarm 15 does not emit an alarm signal due to the attraction state of the magnetic induction sensor 12 and the magnet 13. The device enters the monitoring standby state. Finally, the threaded cover 7 is threaded onto the top of the outer side of the placement cylinder 5 to protect the internal components of the placement cylinder 5.

[0044] S2: When cable 1 is not stolen, cable 1 remains stationary, clamping block 2, assembly block 3 and steel rope 4 do not move. Due to the stable attraction force between magnetic induction sensor 12 and magnet 13, the positions of components such as disc 10 and moving plate 9 remain unchanged, and wireless magnetic induction alarm 15 remains in a non-alarm state. At the same time, the buried installation of placement cylinder 5 and the protection of threaded cover 7 reduce the interference of external environment on internal components.

[0045] S3: When cable 1 is stolen and shifted, cable 1 moves clamping block 2 synchronously. Clamping block 2 pulls steel rope 4 through assembly block 3. After being stressed, steel rope 4 moves disc 10 upward. Disc 10 moves moving plate 9 vertically within the moving hole of inner frame 8. At the same time, magnet 13 at the bottom of disc 10 moves together and gradually separates from magnetic induction sensor 12 at the top of inner frame 8. When moving plate 9 moves, it moves base plate 11 upward. Base plate 11 compresses spring 14 to make it contract. When magnet 13 is completely separated from magnetic induction sensor 12, the sensing signal of magnetic induction sensor 12 is interrupted, triggering wireless magnetic induction alarm 15 fixedly installed on top of disc 10. Wireless magnetic induction alarm 15 sends alarm signal to staff through wireless transmission, realizing timely alarm of cable theft. If maintenance of internal components of the device is required later, threaded cover 7 can be removed for operation.

[0046] The foregoing has provided a detailed description of the wireless sensing-based cable anti-theft alarm device provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
