Perimeter protection device with omega-shaped thorn belt and self-recovery sensor belt

Abstract

This utility model discloses a perimeter protection device that uses a dual-type Ω-shaped barbed tape and a self-recovering sensor tape in synergy. It includes: a basic Ω-shaped barbed tape, whose first Ω-shaped hollow cavity contains no information sensing wires, used to reinforce the perimeter and provide a base for the self-recovering sensor tape; a sensing Ω-shaped barbed tape, whose second Ω-shaped hollow cavity contains embedded information sensing wires, used to reinforce the perimeter and trigger an alarm when cut; and a self-recovering sensor tape, whose insulated third Ω-shaped hollow cavity has a flexible conductive strip at its top and bottom, normally non-contacting, and is adhered to the surface of the basic Ω-shaped barbed tape via a bottom insulated I-shaped support base. When the self-recovering sensor tape is pressed, the two conductive strips touch, causing a change in resistance and triggering an alarm. When cut, the flexible conductive strips disconnect, triggering an open-circuit alarm. The combination of these three components is suitable for security upgrades to existing wire mesh, solid walls, and multi-layered wire mesh, extending the time to breach and reducing the risk of missed or false alarms.

Description

Technical Field

[0001] This utility model belongs to the field of perimeter security technology, specifically involving a perimeter protection device that uses two types of Ω-shaped barbed tape and self-recovering sensor tape in synergy. It is suitable for the security upgrade and transformation of existing perimeter facilities such as wire mesh, solid walls, and multi-layered conical cage nets, realizing the deep integration of physical and technical security, significantly improving the protection capability of existing perimeters and eliminating false alarms and missed alarms. Background Technology

[0002] When enhancing the protective capabilities of existing perimeter facilities (barbed wire, solid walls, multi-layered corrugated wire mesh), technical security measures such as adding vibration fiber optic cables, radar, and video surveillance are commonly used, but these methods have the following drawbacks: Traditional technical security measures offer limited enhancement to physical protection: the technical security added to barbed wire does not overlap with physical security, making existing physical security facilities vulnerable to shearing and breaching; the technical security added to solid walls lacks sufficient climbing protection and cannot delay ladder or rope climbing intrusion; the horizontal support connectors of multi-layered coniferous wire mesh are made of ordinary iron wire or barbed wire, resulting in a weak structure, and the added technical security measures fail to fully cover the iron wire or barbed wire, thus failing to block the path of breaching the mesh by shearing the horizontal support connectors. Traditional technical security measures have a high false alarm rate: vibration fiber optic cables are easily interfered with by strong winds and animal contact, while radar and video are affected by ambient light and weather, resulting in frequent false alarms and the risk of missed alarms. Physical and technical security measures are disconnected: exposed technical security sensors are vulnerable to lightning strikes or human damage, resulting in high maintenance costs; physical damage and alarm signals lack real-time linkage, leading to low response efficiency. Utility Model Content

[0003] To achieve the above objectives, this utility model provides a perimeter protection device that combines a dual-type Ω-shaped barbed tape with a self-recovering sensor tape. Specifically, it includes: a basic Ω-shaped barbed tape (1), which has a first Ω-shaped hollow cavity (11) without information sensing wires; the basic Ω-shaped barbed tape (1) is used to be installed horizontally or vertically on existing wire mesh, solid walls, or multi-layered coniferous wire mesh to reinforce physical protection and provide a bonding base for the self-recovering sensor tape (3). The sensing Ω-shaped barbed strip (2) has a second Ω-shaped hollow cavity (21) and an information sensing line (23) embedded in the second Ω-shaped hollow cavity (21); the sensing Ω-shaped barbed strip (2) is used to be installed horizontally or vertically on existing wire mesh, solid walls or multi-layer snake belly wire mesh to reinforce physical protection, and to trigger an alarm by disconnecting through the information sensing line (23) when it is cut. The self-resetting sensing tape (3) includes an insulating I-shaped support base (32) and a self-resetting flexible structure located above the insulating I-shaped support base (32). The self-resetting flexible structure has an insulating third Ω-shaped hollow cavity (31). A flexible conductive strip (33) is provided at the top and bottom of the inner wall of the third Ω-shaped hollow cavity (31). The two flexible conductive strips (33) do not contact each other under normal conditions. The self-resetting sensing tape (3) is attached to the surface of the basic Ω-shaped protruding strip (1) through the insulating I-shaped support base (32). The basic Ω-shaped barbed strip (1), the sensing Ω-shaped barbed strip (2), and the self-recovering sensing strip (3) are used in combination to adapt to the upgrading and transformation of any of the existing perimeter facilities, such as existing wire mesh, solid walls, or multi-layered serpentine wire mesh.

[0004] Basic type Ω-shaped protruding barb band (1) Structure: The strip steel (thickness ≥ 0.4 mm) is stamped and formed with an Ω-shaped cross section. The diameter of the first Ω-shaped hollow cavity (11) is ≥ 2 mm. The wing surface is formed by cutting and folding or direct punching to form anti-climbing spikes (12). The spikes (12) are in the shape of trapezoid, triangle, or sawtooth. The spikes (12) formed by cutting and folding can be folded at an angle of 30°-180°. The spikes (12) formed by direct punching cannot be folded.

[0005] Functions: Pure physical protection to prevent cutting and breaking of nets and climbing intrusion, without alarm function; as a carrier for self-recovering sensor tape (3).

[0006] Horizontal installation: Pure physical protection function: Deployed in areas that only require physical protection reinforcement (such as weak points in barbed wire); Carrier function: Deployed as a bonding carrier in the area where the self-replicating sensor tape (3) needs to be bonded (such as the top or middle of the perimeter).

[0007] Vertical installation: Mesh construction: It intersects with the horizontally deployed Ω-shaped barbed strips to form a three-dimensional protective net; Independent physical defense: Deployed in low-risk areas to enhance the physical defense capabilities of existing perimeter facilities.

[0008] Sensory Ω-shaped protruding spikes (2) Structure: The difference between the basic Ω-shaped protruding barb (1) and the sensing Ω-shaped protruding barb (2) is that the information sensing line (23) is embedded in the second Ω-shaped hollow cavity (21).

[0009] Function: It retains all the functions of the basic Ω-shaped barb strip (1) and adds technical protection capabilities, triggering an alarm when the embedded information sensing line (23) is broken due to shearing damage.

[0010] Lateral installation: Deployed at locations where existing perimeter facilities require upgraded protection. When cut, it triggers an alarm. Its physical protection performance is consistent with the basic Ω-shaped barbed strip (1).

[0011] Vertical installation: Deployed in high-risk areas prone to shearing, such as wire mesh, the top perimeter of solid walls, and multi-layered wire mesh.

[0012] Self-repairing sensor band (3) Structure: It is a self-resetting flexible structure; the upper half of the cross section is a deformable self-resetting insulating third Ω-shaped hollow cavity (31), and a flexible conductive strip (33) is distributed at the top and bottom of the inner wall of the third Ω-shaped hollow cavity (31). The two flexible conductive strips (33) are normally not in contact; the lower half of the cross section is an insulating I-shaped support base (32).

[0013] Installation: The self-recovering sensor tape (3) is applied to the surface of the basic Ω-shaped barbed tape (1) after being bonded to the insulating I-shaped support base (32) with a weather-resistant adhesive layer.

[0014] Function: Climbing monitoring: When the self-recovery sensing strip (3) is touched, the two normally non-contact flexible conductive strips (33) on the inner wall of the third Ω-shaped hollow cavity (31) touch each other, causing a change in the resistance between the lines and triggering an alarm; Cut detection: When the self-recovery sensing strip (3) is cut, the conductive strip (33) on the inner wall of the third Ω-shaped hollow cavity (31) breaks, causing the conductive circuit to open and triggering an alarm.

[0015] Composite protection system The combination of basic Ω-shaped barbed strip (1), sensing Ω-shaped barbed strip (2), and self-repairing sensing strip (3) can be used to adapt to different perimeter facilities. Wire mesh renovation: Horizontally deploy sensing Ω-shaped barbed strips (2) to realize cut alarm, vertically and horizontally deploy basic Ω-shaped barbed strips (1) to build a physical protection grid, and attach self-recovering sensor strips (3) to the surface of basic Ω-shaped barbed strips (1) to realize climbing monitoring and cut alarm; Solid wall protection: The top horizontal deployment of basic Ω-shaped barbed strips (1) and sensing Ω-shaped barbed strips (2) upgrades the protection capability of the existing perimeter. Self-recovering sensor strips (3) are pasted on the surface of the basic Ω-shaped barbed strips (1) to monitor climbing and cutting intrusion behavior. Multi-layer rolling cage reinforcement: Horizontally deployed sensing Ω-shaped barbed strips (2) support the rolling cage, strengthen the physical protection of the rolling cage support connectors, and trigger an alarm after being cut to realize the technical protection of the rolling cage support connection; the top deployed basic Ω-shaped barbed strips (1) with self-recovering sensor strips (3) pasted on the surface are used to monitor climbing and crossing intrusion behavior.

[0016] The effective effects of this utility model are: Enhanced physical defense capabilities: The basic Ω-shaped barbed tape provides pure physical protection against shearing and climbing intrusion, extending the time for intrusion to break through; the sensing Ω-shaped barbed tape provides physical protection while also providing real-time alarm for shearing, blocking the intrusion path; Reduce the risk of false alarms and missed alarms: Only physical acts of damage will trigger the alarm. Cutting the sensing Ω-shaped barb strip will cause the embedded information sensing line to break and trigger the alarm; or climbing or cutting the self-recovering sensing strip will cause the two normally non-contact flexible conductive strips embedded to touch, causing a change in the resistance between the lines or the conductive strips to break and trigger the alarm, thus avoiding environmental interference with the technical protection. Achieving coordinated action: The basic Ω-shaped barbed tape can not only reinforce the physical protection of existing perimeter facilities, but also provide physical support for the self-recovering sensor tape to achieve climbing intrusion protection; the sensing Ω-shaped barbed tape enhances physical protection capabilities and embeds information sensor lines to achieve cut alarm; the three types of components can be combined as needed to build a real-time response system that deeply integrates physical and technical defenses, covering scenarios of cutting through fences and climbing over intrusion.

[0018] The basic Ω-shaped barbed strip (1) and the sensing Ω-shaped barbed strip (2) adopt the same Ω-shaped cross-section structure (strip thickness ≥ 0.4 mm, hollow cavity diameter ≥ 2 mm), the only difference being: Basic Ω-shaped protruding barb (1): The first Ω-shaped hollow cavity (11) has no embedded information sensing line and only provides physical protection; Sensing Ω-shaped barbed strip (2): It can provide physical protection and also achieve technical protection by embedding information sensing line (23) in the second Ω-shaped hollow cavity (21) to trigger a real-time alarm when it is cut; Self-resetting sensing strip (3): Two normally non-contact flexible conductive strips (33) are embedded in the third Ω-shaped hollow cavity (31) of the self-resetting flexible structure. When the self-resetting sensing strip (3) is used, it is pasted on the surface of the basic Ω-shaped spike strip (1) using an insulating I-shaped support base (32). When it is climbed, invaded, pressed or cut, the two normally non-contact conductive strips (33) inside will touch each other, causing a change in resistance or the conductive strips (33) will disconnect themselves to trigger an alarm. Its alarm function is not affected by the type of carrier.

[0019] Example 1: Modification of Wire Mesh Perimeter On the perimeter of the existing wire mesh, sensor-type Ω-shaped barbed strips (2) are installed horizontally at 200mm intervals, and basic Ω-shaped barbed strips (1) are installed vertically at 500mm intervals. The two types of Ω-shaped barbed strips, which are intersected in the longitudinal and transverse directions, form a three-dimensional protective net, which strengthens the physical protection of the existing wire mesh. The sensor-type Ω-shaped barbed strips (2) trigger an alarm when cutting intrusion, which adds technical protection. A basic Ω-shaped barbed band (1) is horizontally installed on the upper part and top of the existing wire mesh perimeter, and a self-resetting sensor band (3) is pasted on the surface of the basic Ω-shaped barbed band (1). When climbing, intruding, touching, or cutting the self-resetting sensor band (3), a resistance change or open circuit alarm is triggered, which improves the climbing protection capability of the existing wire mesh perimeter and effectively avoids false alarms caused by environmental interference.

[0020] Example 2: Upgrade of Solid Wall Protection Ω-shaped basic type Ω-shaped protruding barbs (1) and sensing type Ω-shaped protruding barbs (2) are installed horizontally on the top of the existing solid wall to strengthen the physical protection of the top of the existing solid wall. The sensing type Ω-shaped protruding barbs (2) will trigger an alarm when they are cut. Basic type Ω-shaped protruding barbs (1) with self-recovering sensor tape (3) is installed at the climbing intrusion path. The self-recovering sensor tape (3) will trigger an alarm when the climber touches or cuts the self-recovering sensor tape (3), thereby improving the climbing protection monitoring capability of the existing solid wall.

[0021] Example 3: Reinforced Protection with Roller Netting On the existing multi-layer rolling cage net protection body, a sensing Ω-shaped barbed strip (2) is installed horizontally at 350mm intervals as a horizontal support connector for the multi-layer rolling cage net. This not only strengthens the physical protection capability of the rolling cage net, but also adds a technical protection function to the horizontal support connector of the rolling cage net. A basic Ω-shaped barbed strip (1) is installed horizontally on the top of the existing multi-layer rolling cage net protection body, and a self-recovering sensor strip (3) is continuously pasted on the surface of the basic Ω-shaped barbed strip (1). When climbing intrusion touches or cuts the self-recovering sensor strip (3), an alarm is triggered, which improves the climbing protection monitoring capability of the existing perimeter and effectively avoids false alarms caused by environmental interference.
