[0002] Electronic fence is the most advanced perimeter anti-theft alarm system. The system mainly consists of three parts: electronic fence host, front-end accessories, and back-end control system. Usually, the electronic fence host is installed outdoors along the original fence (such as brick wall, concrete wall or iron fence). The pulse electronic fence host is also usually outdoors. The alarm signal is transmitted to the control keyboard of the back-end control center through the signal transmission equipment, which displays the working status of the defense zone and remotely controls the deployment and withdrawal of the external pulse host.

DETAILED DESCRIPTION

[0024] Please refer to Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 This is a schematic diagram of the overall structure of the electronic fence early warning device of the utility model; Figure 2 This is a schematic diagram of the internal structure of the fence pole of the electronic fence early warning device of the utility model; Figure 3 The electronic fence early warning device comprises: a base 1, a fence rod 2 is fixedly connected to the top surface of the base 1, and a plurality of fence wires 3 are connected to the outer surface of the fence rod 2, and the fence wires 3 are provided with a protective mechanism and an early warning mechanism:

[0025] The protective mechanism includes a take-up box upper cover 4, a connecting rod 5, a take-up drum 6, a coil spring 7, a limit column 8 and a take-up box lower cover 9, wherein the take-up box upper cover 4 is threadedly mounted on the inner surface of the fence rod 2, the connecting rod 5 is rotatably mounted on the take-up box upper cover 4, the take-up drum 6 is fixedly sleeved on the connecting rod 5, the fence line 3 is wound on the take-up drum 6, the coil spring 7 is snap-connected to the other end of the connecting rod 5, the limit column 8 is snap-connected to the other end of the coil spring 7, and the take-up box lower cover 9 is fixedly connected to the other end of the limit column 8;

[0026] The pre-alarm mechanism includes a fixed plate 10, an alarm 11, a trigger ring 12 and a discharge device 13. The fixed plate 10 is fixedly connected to the inner surface of the fence rod 2, the alarm 11 is fixedly installed on the top of the fixed plate 10, the trigger ring 12 is fixedly sleeved on the fence line 3, the fixed plate 10 and the trigger ring 12 are movably sleeved on the fence line 3, and the discharge device 13 is fixedly installed on the inner wall of the fence rod 2.

[0027] like Figure 3 As shown, a mounting plate 14 is fixedly connected to the top of the fence rod 2, an infrared thermal imaging sensor 15 is fixedly mounted on one end of the mounting plate 14, and a buzzer 16 is mounted on the other end of the mounting plate 14;

[0028] The infrared thermal imaging sensor 15 and the buzzer 16 can detect the livestock and drive them away.

[0029] like Figure 3 As shown, the size of the take-up drum 6 matches the size of the fence line 3, and the upper cover 4 of the take-up box, the connecting rod 5, the take-up drum 6 and the coil spring 7 are located on the same horizontal line;

[0030] By matching the size of the take-up drum 6 with the size of the fence wire 3 , the possibility of the fence wire 3 getting stuck when being wound up can be reduced.

[0031] like Figure 3 As shown, the thickness of the coil spring 7 is matched with the spacing between the wire take-up drum 6 and the lower cover 9 of the wire take-up box.

[0032] By matching the thickness of the coil spring 7 with the spacing between the take-up drum 6 and the lower cover 9 of the take-up box, the coil spring 7 can be confined in the lower cover 9 of the take-up box, so that the coil spring 7 can operate normally.

[0033] like Figure 1 As shown, the plurality of fence wires 3 are distributed on the fence pole 2 at equal distances, and the fence wires 3 in the fence pole 2 are all covered with an insulating layer;

[0034] By distributing a plurality of fence lines 3 at equal distances on the fence pole 2, it is possible to reduce the problem of livestock passing smoothly due to the large distance between the fence lines 3.

[0035] like Figure 1 As shown, four expansion bolts 17 are also installed on the top surface of the base 1, and the four expansion bolts 17 are symmetrically distributed about the vertical center line of the fence rod 2;

[0036] By symmetrically installing four expansion bolts 17 on the fence rod 2, the stability of the fence rod 2 can be enhanced.

[0037] The working principle of the electronic fence pre-alarm device provided by the utility model is as follows:

[0038] Step 1: When in use, first stably wind the fence wire 3 on the take-up drum 6, then snap-fit ​​and install both ends of the coil spring 7, close the lower cover 9 of the take-up box, and then thread it on the inner wall of the fence rod 2, and then install the fence rod 2 in a suitable position;

[0039] The second step: when livestock approach the electronic fence, the infrared thermal imaging sensor 15 senses it and starts the buzzer 16 to make a sound to drive the livestock away. When the infrared thermal imaging sensor 15 fails or the livestock forcibly passes through and touches the fence line 3, the weak current of the fence line 3 drives the livestock away. When the livestock quickly touches the fence line 3, the weak current driving capacity of the fence line 3 will be insufficient. At this time, the protective mechanism will force the stored fence line 3 to extend to reduce accidents caused by the fence line 3 entangled with the livestock. At the same time, after the fence line 3 is fully extended, the trigger ring 12 is pulled to contact the alarm 11, and the alarm 11 sends a warning signal to prompt the staff to deal with it as soon as possible.
