Description

Technical Field

[0001] This utility model relates to the field of electronic fence technology, and in particular to an electronic fence with a remote alarm and monitoring device. Background Technology

[0002] An electronic fence is a type of active intrusion prevention fence. It counteracts intrusion attempts, repels intruders without threatening human lives, and transmits intrusion signals to security monitoring equipment, ensuring that management personnel can promptly understand the situation in the alarm area and take swift action. An electronic fence system mainly consists of three parts: the electronic fence host, front-end accessories, and the back-end control system. Typically, the electronic fence host is installed outdoors along the existing fence. Pulse electronic fence hosts are also usually located outdoors, transmitting alarm signals to the back-end control center via signal transmission equipment. Electronic fences are widely used in substations, power plants, water plants, residential areas, villa areas, schools, airports, military facilities, prisons, detention centers, and other locations with or requiring fencing.

[0003] Because electronic fence systems require remote alarm and monitoring systems, and monitoring probes have blind spots, multiple monitoring probes are typically installed in the same area to create overlapping fields of view to ensure complete coverage of the electronic fence. However, deploying overlapping cameras in every area of ​​a long-distance electronic fence would significantly increase equipment costs and reduce the utilization rate of the camera devices. Utility Model Content

[0004] To address the problem that deploying cross-view cameras in every area of ​​a long-distance electronic fence would significantly increase equipment costs and reduce the utilization rate of the camera devices, this invention provides an electronic fence with remote alarm and monitoring capabilities to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is:

[0006] An electronic fence with a remote alarm and monitoring device includes a lower support plate, double-arm support rods, wire clamping plate, bidirectional bolts, and fixing device;

[0007] Two double-arm support rods are fixed to the upper end face of the lower support plate. Each double-arm support rod is equipped with a wire pressure plate. The wire pressure plate is provided with a limiting protrusion, which is slidably connected in the gap between the double-arm support rods. Each wire pressure plate is provided with a threaded hole. The two wire pressure plates are threadedly connected to the threads at both ends of the bidirectional bolt through the threaded holes. The bidirectional bolt presses the two wire pressure plates onto the corresponding double-arm support rods by adjusting the distance between the two wire pressure plates. The fixing device is fixedly connected to the lower end face of the lower support plate.

[0008] Furthermore, multiple wire clamps are installed on both of the double-arm support rods.

[0009] Furthermore, the bidirectional bolt causes the two wire pressure plates to move away from each other, pressing the two wire pressure plates against the inner sides of the two double-arm support rods respectively.

[0010] Furthermore, the bidirectional bolt causes the two wire pressure plates to tend to move closer to each other, pressing the two wire pressure plates onto the outside of the two double-arm support rods respectively.

[0011] Furthermore, the fixing device includes a connecting plate, an arc-shaped fixing plate, a guide box, a slider, a conductive cylinder, and a spring. The connecting plate is fixed to the lower end face of the lower support plate. The arc-shaped fixing plate is detachably fixed on the connecting plate. The guide box is fixed on the connecting plate. The slider is slidably connected inside the guide box. The conductive cylinder is fixedly connected to the slider. One end of the conductive cylinder passes through the guide box, and the other end of the conductive cylinder passes through the connecting plate. A spring is installed inside the guide box. The spring causes the slider to have a tendency to move towards the connecting plate.

[0012] Furthermore, the end of the conductive cylinder that passes through the connecting plate is set to be tapered.

[0013] Furthermore, an upper support plate is fixed to the upper end face of the two double-arm support rods, and a camera device is installed on the upper end of the upper support plate.

[0014] Furthermore, the upper support plate is detachably fixed to the upper end of the two double-arm support rods by bolts.

[0015] Furthermore, the connecting plate is provided with an arc-shaped fixing part.

[0016] Furthermore, the wire pressure plate has two wire pressing holes.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. An electronic fence with a remote alarm and monitoring device, comprising two double-arm support rods and multiple sets of wire clamping plates. The spacing between the two wire clamping plates is adjusted by rotating a bidirectional bolt, pressing the metal wire clamping plates onto their respective double-arm support rods. The density of the electric grid within the electronic fence can be adjusted by changing the number and spacing of the wire clamping plates.

[0019] 2. It is equipped with two double-arm support rods, which can clamp two rows of electric grids. By rotating a two-way bolt, two conductor pressure plates are locked at the same time to fix the two rows of electric grids, which simplifies the installation steps and improves installation efficiency.

[0020] 3. This electronic fence is equipped with two sets of electric grids, which can separately identify short-circuit signals between metal wires and short-circuit signals between metal wires and ground in the two sets of electric grids to determine whether an intruder has climbed over the fence or has been repelled. When both the outer and inner electric grids of the electronic fence in the same area generate contact signals, that is, when an intruder touches the outer electric grid and then the inner electric grid, the intruder is marked as having climbed over the fence, and an alarm is triggered at the control center.

[0021] 4. The system includes conductive cylinders for communication with the metal fence. After installing this electronic fence on the top of the metal fence, the conductive cylinders connect to the metal fence, integrating the metal fence into the detection system and making it part of the electronic fence. When a short-circuit signal is received between the metal fence and the ground, it is determined that an intruder has touched the electronic fence. The camera is then adjusted to face the alarm area, completing the monitoring and recording function. Attached Figure Description

Detailed Implementation

[0033] Specific implementation method one: See Figure 1-6 As shown, an electronic fence with a remote alarm and monitoring device is provided in this embodiment, which includes a lower support plate 101, a double-arm support rod 102, a wire pressure plate 103, a bidirectional bolt 105, and a fixing device 2.

[0034] Two double-arm support rods 102 are fixed to the upper end face of the lower support plate 101. A wire pressure plate 103 is installed on each of the two double-arm support rods 102. A limiting protrusion 104 is provided on the wire pressure plate 103. The limiting protrusion 104 is slidably connected in the gap between the double-arm support rods 102. A threaded hole is opened on each of the two wire pressure plates 103. The two wire pressure plates 103 are respectively threaded to the threads at both ends of the bidirectional bolt 105 through the threaded holes. The bidirectional bolt 105 presses the two wire pressure plates 103 onto the corresponding double-arm support rods 102 by adjusting the distance between the two wire pressure plates 103. The fixing device 2 is fixedly connected to the lower end face of the lower support plate 101.

[0035] Specific Implementation Method Two: See Figure 1-3 As shown, in this embodiment, multiple wire pressure plates 103 are installed on both double-arm support rods 102.

[0036] Specific implementation method three: See Figure 6 As shown, the wire pressure plate 103 of this embodiment has two wire pressing holes.

[0037] Furthermore, the double-arm support rod 102 consists of two vertically fixed square columns, forming a sliding gap between them. The limiting protrusion 104 on the wire clamping plate 103 is a square protrusion, and the width of the gap between the double-arm support rods 102 is the same as the width of the limiting protrusion 104, allowing the limiting protrusion 104 to slide within the gap between the double-arm support rods 102. The limiting protrusion 104 restricts the degree of freedom of the wire clamping plate 103, ensuring that the wire clamping plate 103 can only slide up and down along the centerline of the double-arm support rods 102, preventing the wire clamping plate 103 from rotating on the double-arm support rods 102 and affecting installation efficiency. The bidirectional bolt 105 is used to simultaneously drive the two wire clamping plates 103 to move towards the center or separate to both sides, realizing the fixing and disassembly of the metal wire. During the installation of the electronic fence, the density of the electric grid within the fence can be adjusted by changing the number and spacing of the wire pressure plates to adapt to different usage environments and deter or drive away people or other animals. Both the double-arm support rods 102 and the wire pressure plates 103 are made of insulating material, ensuring that each metal wire is insulated from the others. Short circuit signals between metal wires and between metal wires and the ground are monitored to determine if anyone is touching the electronic fence.

[0038] Furthermore, multiple wire clamps 103 are installed on a double-arm support rod 102. Each wire clamp 103 can fix two metal wires, and the multiple metal wires fixed on the same double-arm support rod 102 form an electric grid. This electronic fence is equipped with two sets of electric grids, which can respectively identify the mutual short circuit signals between metal wires in the two sets of electric grids and the short circuit signals between metal wires to ground to determine whether an intruder has climbed over the fence or has been repelled. When both the outer and inner electric grids of the electronic fence in the same area generate contact signals, that is, when an intruder touches the outer electric grid and then the inner electric grid, the intruder is marked as having climbed over the fence, and an alarm is triggered at the control center.

[0039] Detailed Implementation Method Four: See [link] Figure 1 and 10 As shown, the bidirectional bolt 105 in this embodiment causes the two wire pressure plates 103 to move away from each other, pressing the two wire pressure plates 103 onto the inner sides of the two double-arm support rods 102 respectively.

[0040] Specific implementation method five: See Figure 3 and 9 As shown, the bidirectional bolt 105 in this embodiment causes the two wire pressure plates 103 to move closer to each other, pressing the two wire pressure plates 103 onto the outside of the two double-arm support rods 102 respectively.

[0041] Furthermore, when the two wire clamping plates 103 are pressed against the inner sides of the two double-arm support rods 102, the two sets of electric fences are fixed to the inner sides of the two double-arm support rods 102 respectively. This installation occupies less space and is suitable for installation on the upper part of relatively narrow fences. When the two wire clamping plates 103 are pressed against the outer sides of the two double-arm support rods 102, the two sets of electric fences are fixed to the outer sides of the two double-arm support rods 102 respectively, thereby increasing the distance between the two sets of electric fences and creating a greater obstacle for people climbing over the electronic fence.

[0042] Specific implementation method six: See Figure 7 and 8 As shown, the fixing device 2 in this embodiment includes a connecting plate 201, an arc-shaped fixing plate 202, a guide box 203, a slider 204, a conductive cylinder 205, and a spring 206. The connecting plate 201 is fixed to the lower end face of the lower support plate 101. The arc-shaped fixing plate 202 is detachably fixed on the connecting plate 201. The guide box 203 is fixed on the connecting plate 201. The slider 204 is slidably connected inside the guide box 203. The conductive cylinder 205 is fixedly connected to the slider 204. One end of the conductive cylinder 205 passes through the guide box 203, and the other end of the conductive cylinder 205 passes through the connecting plate 201. The spring 206 is installed inside the guide box 203. The spring causes the slider 204 to have a tendency to move towards the connecting plate 201.

[0043] Furthermore, after the electronic fence is installed on the upper part of the metal fence, the conductive cylinder 205 is used to conduct electricity with the metal fence. One end of the conductive cylinder 205 passes through the connecting plate 201 and contacts the metal fence, and the spring 206 is used to push the conductive cylinder 205 to press firmly against the metal fence. The conductive cylinder 205 is connected to the electronic fence's control system through a wire, connecting the metal fence to the detection system, making the metal fence part of the electronic fence. When a short circuit signal between the metal fence and the ground is received, it is determined that an intruder has contacted the electronic fence, and the camera device is adjusted to turn towards the alarm area to complete the monitoring and recording function.

[0044] Detailed implementation method seven: See Figure 8 As shown, in this embodiment, the end of the conductive cylinder 205 that passes through the connecting plate 201 is set to be tapered.

[0045] Furthermore, the tapered end of the conductive cylinder 205 is used to pierce the surface oxide layer and anti-rust paint of the metal fence to reduce the resistance between the conductive cylinder 205 and the metal fence. During installation, the conductive cylinder 205 can be pulled and quickly released. The conductive cylinder 205 is pushed by the spring 206 and hits the metal fence, making it easier for the conductive cylinder 205 to pierce the surface oxide layer and anti-rust paint of the metal fence.

[0046] Detailed Implementation Method Eight: See also Figure 1As shown, in this embodiment, an upper support plate 301 is fixed to the upper end face of the two double-arm support rods 102, and a camera device 302 is installed on the upper end of the upper support plate 301.

[0047] Furthermore, the camera device 302 is a 360° rotating camera probe, and its rotation is driven by the electronic fence's control system. The electronic fence's electric grid uses a zoned access control system, which can determine the location where an intruder touches the grid. When an intruder touches the grid, the electronic fence control system identifies the intruder's location and rotates the camera device 302 to the corresponding area to achieve monitoring and recording. This function reduces the number of camera devices 302 required in the same area, achieves full coverage of the electronic fence by rotating the camera device 302, and improves the utilization rate of the camera device 302.

[0048] Detailed Implementation Method Nine: See also Figure 1 As shown, in this embodiment, the upper support plate 301 is detachably fixed to the upper ends of the two double-arm support rods 102 by bolts. This facilitates the installation and removal of the wire clamping plate 103, and also facilitates the feeding of the metal wire between the two double-arm support rods 102 to fix the metal wire.

[0049] Detailed Implementation Method Ten: See [link / details] Figure 7-8 As shown, the connecting plate 201 in this embodiment is provided with an arc-shaped fixing part. The arc-shaped fixing part and the arc-shaped fixing plate 202 are spliced ​​together to form a ring shape for fixing to the metal fence.
