Description

Technical Field

[0001] The utility model relates to the technical field of electronic fences, in particular to an electronic fence with an alarm function. Background Art

[0002] An electronic fence is an advanced perimeter anti-theft alarm system, which mainly consists of three parts: an electronic fence host, front-end accessories, and a rear-end control system.

[0003] An electronic fence is a hidden restraint. Since it has no posts and no wires and is very simple to operate, it is widely used. It is mainly installed on a wall with a certain height. When the existing electronic fence alarms, it generally sends the alarm information directly to the control terminal or the bound mobile phone. However, in the face of untimely information reception, it is impossible to give an early warning by lighting a warning light and sounding an alarm at the faulty location, which limits the way for staff to receive early warning information and cannot accurately locate the faulty location, affecting preventive and maintenance measures.

[0004] Therefore, we provide an electronic fence with an alarm function. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an electronic fence with an alarm function for the above-mentioned existing technical problems, so as to achieve the effect of having an alarm function.

[0006] In view of this, the utility model provides an electronic fence with an alarm function, including a support cylinder, and a connecting rod fixedly arranged inside the support cylinder. There are several support cylinders, and several connecting wires are inserted into the support cylinders. One side of the connecting wire extending into the support cylinder is fixedly connected with a connecting column, and the connecting column is fixedly connected with the connecting rod. An equivalent resistance block is arranged between every two connecting wires, and the equivalent resistance block is fixedly connected with the connecting rod. A current detector is arranged between every two connecting rods. The current detector is located below the connecting wire, and a warning lamp and a warning horn are arranged on one side of the current detector.

[0007] Preferably, a detection wire is fixedly connected to the lower end of the connecting rod, and an auxiliary wire is fixedly connected to the lower end of the connecting rod. The auxiliary wire is located below the detection wire.

[0008] Preferably, an insulating column is arranged between the detection wire and the auxiliary wire, and the insulating column is fixedly arranged outside the connecting rod.

[0009] Preferably, the detection wire is fixedly connected to the auxiliary wire through a closed connecting wire, and the closed connecting wire is fixedly connected to the detection wire.

[0010] Preferably, the closed connection line is fixedly connected to the current detector, and the current detector is fixedly connected to a support plate.

[0011] Preferably, an active switch is arranged between the current detector and the support plate. The alarm lamp and the alarm horn are fixedly arranged on one side of the support plate, and the alarm horn is located between the two alarm lamps.

[0012] Preferably, the closed connection line is inserted into a protective housing. The protective housing is fixedly connected to a support wall. The support wall is fixedly connected to the support cylinder. The upper end of the support cylinder is connected with a closed top in a clamping manner. The connecting rod is connected with the connecting rod in a clamping manner, and the connecting rod is inserted into the support wall.

[0013] Compared with the prior art, the utility model provides an electronic fence with an alarm function, having the following beneficial effects:

[0014] 1. In the utility model, the current detector detects the current of a plurality of connecting lines between adjacent two connecting rods. The current flows under the support of the connecting rods, and its outer side is connected with an equivalent resistance block through a plurality of connecting columns, and a parallel circuit is formed under the connection of the connecting lines between the two connecting rods on both sides. When one of the connecting lines is disconnected, when the current in the parallel circuit flows, it will cause the magnitude of the current passing through the resistor to change, thereby causing the magnitude of the current detected by the current detector to change, making the actual detected value of the current detector inconsistent with the current magnitude under the preset normal operation condition. Thus, the current detector will automatically turn on the alarm lamp and the alarm horn.

[0015] 2. In the utility model, through the flashing of the alarm lamp and the sounding of the alarm sound of the alarm horn, the staff can hear the alarm sound in time and quickly find the fault location, thereby improving the warning function of the device and being able to quickly locate the fault location, and improving the security effect when the device is used.

[0016] 3. In the utility model, when the current detector detects a change in the current, the current detector, under the connection of the support plate, operates the alarm lamp and the alarm horn, making the two alarm lamps light up and the alarm horn emit an alarm sound, improving the speed for the staff to hear and see. When repairing the fault, by turning on the active switch, the connection between the current detector and the support plate is disconnected. By closing the active switch, it can be detected whether the fault repair is completed.

[0017] The parts not involved in the device are the same as the prior art or can be implemented by using the prior art. The utility model has a simple structure and is convenient to operate. Description of the Drawings

[0025] Embodiment 1

[0026] An electronic fence with an alarm function, such as Figures 1-4As shown in the figure, it includes a support cylinder 1 and a connecting rod 4 fixedly arranged inside the support cylinder 1. There are several support cylinders 1, and several connecting wires 2 are inserted into the support cylinders 1. One side of the connecting wire 2 extending into the support cylinder 1 is fixedly connected with a connecting column 5, and the connecting column 5 is fixedly connected with the connecting rod 4. An equivalent resistance block 6 is arranged between every two connecting wires 2, and the equivalent resistance block 6 is fixedly connected with the connecting rod 4. A current detector 11 is arranged between every two connecting rods 4. The current detector 11 is located below the connecting wire 2. An alarm lamp 14 and an alarm horn 15 are arranged on one side of the current detector 11. When the device is running, the current detector 11 detects the current of multiple connecting wires 2 between two adjacent connecting rods 4. The current flows to multiple connecting columns 5 and equivalent resistance blocks 6 outside the connecting rod 4 under the support of the connecting rod 4, and forms a parallel circuit under the connection of the connecting wires 2 between the two side connecting rods 4. When one of the connecting wires 2 is disconnected, when the current in the parallel circuit flows, it will cause the magnitude of the current passing through the resistor to change, thereby causing the magnitude of the current detected by the current detector 11 to change, making the actual detected value of the current detector 11 inconsistent with the preset current magnitude under normal operation. Therefore, the current detector 11 will automatically turn on the alarm lamp 14 and the alarm horn 15. Through the flashing of the alarm lamp 14 and the sounding of the alarm sound of the alarm horn 15, the staff can hear the alarm sound in time and quickly find the fault location, thereby improving the early warning function of the device and being able to quickly locate the fault location, and improving the security effect when the device is used.

[0027] As Figures 1-4 shown, the lower end of the connecting rod 4 is fixedly connected with a detection wire 7, and the lower end of the connecting rod 4 is fixedly connected with an auxiliary wire 9. The auxiliary wire 9 is located below the detection wire 7. An insulating column 8 is arranged between the detection wire 7 and the auxiliary wire 9. The insulating column 8 is fixedly arranged outside the connecting rod 4. Through the supporting and flowing effect of the current by the detection wire 7 and the auxiliary wire 9 between two adjacent connecting rods 4, and the insulating isolation effect of the insulating column 8 on the detection wire 7 and the auxiliary wire 9 on the same connecting rod 4, the stability of the current flow is ensured, and the safe operation of the detection wire 7 and the auxiliary wire 9 during their respective work is ensured, preventing the current between the two from affecting each other.

[0028] As Figures 1-4 shown, the detection wire 7 is fixedly connected with the auxiliary wire 9 through a closed connecting wire 10. The closed connecting wire 10 is fixedly connected with the detection wire 7. By arranging the closed connecting wire 10 between the detection wire 7 and the auxiliary wire 9, the integrity of the closed loop is ensured, thereby improving the stability and accuracy of the detection of the flowing current.

[0029] Embodiment 2

[0030] An electronic fence with an alarm function, as Figures 1-4As shown, the closed connection line 10 is fixedly connected to the current detector 11. The current detector 11 is fixedly connected to a support plate 12. An active switch 13 is arranged between the current detector 11 and the support plate 12. An alarm lamp 14 and an alarm horn 15 are fixedly arranged on one side of the support plate 12, and the alarm horn 15 is located between the two alarm lamps 14. When the current detector 11 detects a change in current, the current detector 11, under the connection of the support plate 12, causes the alarm lamp 14 and the alarm horn 15 to operate, making the two alarm lamps 14 light up and the alarm horn 15 emit an alarm sound, improving the speed at which the staff can hear and see. When repairing a fault, by opening the active switch 13, the connection between the current detector 11 and the support plate 12 is disconnected. By closing the active switch 13, it is possible to detect whether the fault repair is completed.

[0031] As Figures 1-4 shown, the closed connection line 10 is inserted into a protective housing 16. The protective housing 16 is fixedly connected to a support wall 17. The support wall 17 is fixedly connected to a support cylinder 1. The upper end of the support cylinder 1 is clamped and connected to a closed top 3. The connecting rod 4 is clamped and connected to the connecting rod 4. The connecting rod 4 is inserted into the support wall 17. Under the support of the support wall 17, the support cylinder 1 and the connecting rod 4 are stably placed. And under the clamping effect of the closed top 3, the safety inside the support cylinder 1 is ensured and the position of the connecting rod 4 is stably supported. At the same time, under the protection of the protective housing 16 for the closed connection line 10, its stability and safety during operation are ensured.

[0032] Working principle: The current detector 11 detects the current of the multiple connection lines 2 between two adjacent connecting rods 4. The current flows to the multiple connection posts 5 and equivalent resistance blocks 6 outside it under the support of the connecting rod 4, and a parallel circuit is formed under the connection of the connection lines 2 between the two connecting rods 4 on both sides. When one of the connection lines 2 is disconnected, when the current flows through the parallel circuit, it will cause a change in the magnitude of the current passing through the resistor, thereby causing a change in the magnitude of the current detected by the current detector 11, making the actual detected value of the current detector 11 inconsistent with the preset normal operating current magnitude. Thus, the current detector 11 will automatically turn on the alarm lamp 14 and the alarm horn 15. Through the flashing of the alarm lamp 14 and the sounding of the alarm sound of the alarm horn 15, the staff can timely hear the alarm sound and quickly find the fault location, thereby improving the warning function of the device and being able to quickly locate the fault location, and improving the security effect when the device is used.

[0033] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
