As shown in fig. 1-6, embodiment 1 is an alarm device for preventing cable from being cut, which comprises a fixed box 10, wherein a plurality of connecting frames 11 symmetrically distributed are fixedly connected to the fixed box 10, vibration monitoring modules are arranged in the fixed box 10, a protection box 12 fixedly connected to one side, far away from the fixed box 10, of the connecting frames 11, a cable 1 passes through the protection box 12, a fixing frame 13 fixedly connected to the inside of the protection box 12, a first conductive piece 14 arranged in the protection box 12, an alarm module 15 arranged in the protection box 12 and electrically connected with the first conductive piece 14, an alarm module 15 used for sending out alarm information under a preset abnormal condition or emergency state, a power supply 16 arranged in the protection box 12, the power supply 16 used for providing power for the alarm module 15, the alarm module 15 electrically connected with the power supply 16, an elastic piece 17 fixedly connected to the part, located in the protection box 12, of the elastic piece 17 electrically connected with the power supply 16, fixedly connected to one side, far away from the cable 1, of the elastic piece 17, of the second conductive piece 18 in contact fit with the first conductive piece 14, the inside of the fixed box 10, and the fixed assembly 18 used for fixing the second conductive piece 18.
As shown in fig. 3-6, the fixing assembly comprises a C-shaped frame 20 fixedly connected to one side of a fixing frame 13, an umbrella-shaped member 21 arranged on one side of the C-shaped frame 20 far away from the fixing frame 13, a sliding rod 22 slidably connected to the C-shaped frame 20, the sliding rod 22 slidably matched with the first conductive member 14, a plurality of magnetic attraction members 23 arranged in the umbrella-shaped member 21 and electrically connected with a power supply 16, a third conductive member 24 fixedly connected to the second conductive member 18 through an insulating member, and the third conductive member 24 magnetically matched with the magnetic attraction members 23.
This device monitors cable 1 through the vibration monitoring module in the fixed box 10 in the in-process of placing, when birds fall on to cable 1, cable 1 can take place the vibration, first drive elastic component 17 and second electrically conductive piece 18 vibrate when cable 1 receives the vibration influence, the first time of vibration monitoring module in the fixed box 10 receives the signal, but the vibration frequency of cable 1 can't make elastic component 17 and second electrically conductive piece 18 swing to when second electrically conductive piece 18 contacted with first electrically conductive piece 14 this moment, first electrically conductive piece 14 can not form the passageway with second electrically conductive piece 18, and can not trigger the alarm of alarm module 15, prevent that vibration monitoring module in the fixed box 10 from receiving the signal after, make alarm module 15 send the alarm, thereby the surprise is to birds, cause birds to keep away from cable 1 rapidly, make cable 1 take place vibration once more, so reduce the probability of misjudgement.
