[0020] The utility model provides a displacement alarm device for an electronic fence, comprising a fence 101, a support column 102, a mounting column 103 and a detection component 104, wherein the detection component 104 comprises a tension line 105, a slider 106, a first spring 107, a second spring 108, a gear 109, a rack 110, an alarm component 111, a guide rod 112, an encoder 113 and an audible and visual alarm 114, wherein the tension line 105 comprises a first steel wire rope 115, a tensioner 116 and a second steel wire rope 117, wherein the tension line 105 pulls the slider 106 to move when subjected to an external force, and the slider 106 drives the rack 110 to move, thereby causing the rack 110 to drive the gear 109 to rotate, and the rotation of the gear 109 is detected by the alarm component 111, and it can be understood that the aforementioned scheme can be used to avoid damage to the alarm component 111, and can also be used to improve the stability of the slider 106 when it moves.
[0021] According to this specific implementation, the support column 102 is installed on the fence 101 , and the installation column 103 is installed on the fence 101 . There are two support columns 102 , which are respectively located on both sides of the installation column 103 .
[0022] Wherein, the slider 106 is slidably connected to the mounting post 103 and is located inside the mounting post 103, the two ends of the first spring 107 are respectively abutted against the slider 106 and the mounting post 103, the first spring 107 is located inside the mounting post 103, the two ends of the second spring 108 are respectively abutted against the slider 106 and the mounting post 103, the second spring 108 is located inside the mounting post 103, the gear 109 is rotatably connected to the mounting post 103 and is located inside the mounting post 103, the rack 110 is fixedly connected to the slider 106, meshed with the gear 109, and is located on one side of the slider 106, and the alarm component 111 is arranged on the mounting post 103; the detection assembly 104 is provided with a plurality of, and two tension lines 105 are provided in one detection assembly 104, and the two tension lines 105 are respectively located on the left and right sides of the slider 106, and the alarm component 111 can detect the gear 10 9 is detected, and when the rotation angle of the gear 109 exceeds a threshold value, the alarm component 111 sounds an alarm; the plurality of tension wires 105 play a blocking role, and the first spring 107 and the second spring 108 exert an elastic force on the slider 106, so that the slider 106 is in the middle position of the mounting column 103. When the tension wire 105 is subjected to an external force, the tension wire 105 will drive the slider 106 to move left and right, and the slider 106 drives the rack 110 to move left and right, thereby causing the rack 110 to drive the gear 109 to rotate. At this time, the alarm component 111 detects the rotation of the gear 109 and sounds an alarm at the same time. When the tension wire 105 is not subjected to force, the slider 106 can be reset under the action of the first spring 107 and the second spring 108. The purpose of detecting the tension is achieved by detecting the rotation of the gear 109, thereby preventing the detection component 104 from being damaged due to excessive tension.

[0024] At the same time, the encoder 113 is connected to the mounting column 103 and is located inside the mounting column 103, and the input end of the encoder 113 is connected to the gear 109; the sound and light alarm 114 is fixedly connected to the mounting column 103, and is electrically connected to the encoder 113, and is located at one end of the mounting column 103; the rotation of the gear 109 is detected by the encoder 113, and when the rotation angle of the gear 109 exceeds a threshold value, the encoder 113 transmits a signal to the sound and light alarm 114, so that the sound and light alarm 114 is activated, thereby issuing a sound and light alarm.
[0025] In addition, the first steel wire rope 115 is connected to the slider 106 and is located on one side of the slider 106; the tensioner 116 is connected to the first steel wire rope 115 and is located at one end of the first steel wire rope 115; the two ends of the second steel wire rope 117 are respectively connected to the tensioner 116 and the support column 102, and the second steel wire rope 117 is arranged on the tensioner 116; the tension of the tension line 105 is adjusted by the tensioner 116, and then the tension of the tension line 105 located on both sides of the slider 106 is adjusted, so that the slider 106 can be located at the center position of the mounting column 103.
[0026] When using the displacement alarm device for electronic fence of this embodiment, when the tension line 105 is subjected to external force, the tension line 105 pulls the slider 106 to move, the slider 106 drives the rack 110 to move, and the rack 110 drives the gear 109 to rotate. The rotation angle of the gear 109 is detected by the encoder 113. When the rotation angle of the gear 109 exceeds the threshold, the encoder 113 transmits a signal to the sound and light alarm to start the sound and light alarm 114. In this process, the situation of the tension line 105 being subjected to external force is judged by detecting the angle of the gear 109. The encoder 113 is located inside the mounting column 103 to reduce the possibility of damage by external environmental factors. At the same time, the rotation of the gear 109 will not cause damage to the encoder 113, thereby avoiding the problem that the alarm component 111 is damaged and cannot work normally.
