Description

Technical Field

[0001] This utility model relates to the field of safety protection technology, specifically to a tension fence alarm function testing device. Background Technology

[0002] In key security areas such as airports, ammunition depots, high-level classified units, and nuclear power plants, isolation or protective facilities are generally used to ensure security. Among these, tension fences are frequently used, as they detect intrusions by changing the tension of steel wire ropes.

[0003] Tension fences are intelligent perimeter protection systems that detect intrusion by monitoring changes in the tension of metal cables in real time. When the tension of the tension fence changes, it triggers an alarm, alerting security personnel to an intrusion. However, tension fences may malfunction after a period of service, requiring regular or irregular on-site inspections by dedicated personnel to promptly determine the effectiveness of the alarm system. This results in significant manpower costs and low inspection efficiency. Therefore, there is an urgent need to design a new device to address these issues. Utility Model Content

[0004] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a tension fence alarm function testing device.

[0005] According to the present invention, a tension fence alarm function testing device includes a lifting mechanism, a linkage component and a controller, and a spiral rod is configured on the tension fence.

[0006] The lifting mechanism is disposed on the side of the screw rod, the upper end of the linkage is connected to the upper end of the lifting mechanism, and the lower end of the linkage extends to the lower end of the screw rod and contacts the lower end of the screw rod.

[0007] When the upper end of the lifting mechanism is lifted upward, the linkage is pushed upward by the lifting mechanism, which in turn causes the lower end of the screw rod to be lifted by the lower end of the linkage. At this time, the metal cable connected to the screw rod bends.

[0008] The controller is connected to the lifting mechanism.

[0009] Preferably, the linkage component is a plate-shaped structure.

[0010] Preferably, the linkage has a Z-shaped structure.

[0011] Preferably, the lifting mechanism is any one of an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder.

[0012] Preferably, the lifting mechanism is provided with a top rod, and the top of the linkage is welded to the top rod or detachably disposed on the top rod.

[0013] Preferably, the travel distance of the push rod is 10 to 150 mm.

[0014] Preferably, the lifting mechanism has a base, which is fixed to the ground by a fixing member.

[0015] Preferably, the fastener is an anchor bolt or an expansion bolt.

[0016] Preferably, the lower end of the screw rod is detachably disposed on or welded to the lower end of the linkage.

[0017] Preferably, the controller is connected to the lifting mechanism 1 via wires and / or communication protocols.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention, through the cooperation of a controller and a lifting mechanism, enables remote lifting action of the lifting mechanism. This, in turn, drives a screw rod to lift via a linkage, causing the metal cable connected to the screw rod to bend. This allows for testing whether the alarm sounds when the metal cable bends, eliminating the need for on-site inspections and saving significant manpower costs. It also offers high testing efficiency. This invention achieves remote testing of the alarm system connected to the tension fence without altering the original tension fence structure; it only requires the addition of a controller, lifting mechanism, and linkage. The structure is simple, easy to implement, and highly practical. Attached Figure Description

[0030] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0031] This utility model provides a tension fence alarm function testing device, such as... Figure 1 , Figure 2 As shown, the device includes a lifting mechanism 1, a linkage 2, and a controller. A spiral rod 3 is configured on the tension fence. Multiple metal cables 31 are vertically connected to the spiral rod 3. Tension sensors are connected to the metal cables 31. When the metal cables 31 bend, the tension sensors detect the bending force and trigger the alarm.

[0032] The lifting mechanism 1 is located on the side of the screw rod 3. The upper end of the linkage 2 is connected to the upper end of the lifting mechanism 1, and the lower end of the linkage 2 extends to the lower end of the screw rod 3 and contacts the lower end of the screw rod 3. When the upper end of the lifting mechanism 1 is lifted upward, the linkage 2 is pushed upward by the lifting mechanism 1, which in turn causes the lower end of the screw rod 3 to be lifted by the lower end of the linkage 2. At this time, the metal cable 31 connected to the screw rod 3 bends due to the lifting of the screw rod 3, so that the effectiveness of the alarm system of the tension fence can be detected by whether the alarm is triggered.

[0033] Specifically, the controller is connected to the lifting mechanism 1 via a wire, thereby facilitating remote control of the movement of the lifting mechanism 1 by the operator. In a preferred embodiment, existing wireless communication technology is employed, utilizing a communication protocol to enable the controller to control the lifting mechanism 1.

[0034] It should be noted that the lifting mechanism 1 in this application can be a drive device capable of linear reciprocating motion, such as an electric cylinder, pneumatic cylinder, or hydraulic cylinder. An electric cylinder is preferred in this application. The controller is a control device capable of controlling the start or stop of the electric cylinder, as is available in the prior art. In a preferred embodiment, the lifting mechanism 1 is provided with a push rod 11, and the top of the linkage 2 is welded to the push rod 11 or detachably mounted on the push rod 11. In this application, the stroke of the push rod 11 on the lifting mechanism 1 can move within the range of 10mm to 150mm. This utility model allows remote control of the lifting height of the lifting mechanism 1 via the controller, which in turn drives the screw rod 3 to lift via the linkage 2, thereby causing the metal cable 31 connected to the screw rod 3 to bend. This allows for remote testing of whether the alarm sounds when the metal cable 31 bends, eliminating the need for regular or irregular on-site inspections by dedicated personnel, saving significant labor costs, and offering the advantage of high testing efficiency.

[0035] like Figure 2 As shown, the linkage 2 is preferably a Z-shaped structure, and can be a plate-like structure. The lifting mechanism 1 has a base 12, which is fixed to the ground by a fixing member, preferably an anchor bolt or an expansion bolt.

[0036] It should be noted that the lower end of the screw rod 3 can be detachably configured or welded to the lower end of the linkage 2, and the specific configuration can be flexibly selected according to the actual application scenario.

[0037] This invention enables remote testing of the alarm system containing the tension fence by simply adding a controller, lifting mechanism 1, and linkage component 2 without altering the original tension fence structure. It is simple in structure, easy to implement, and highly practical.

[0038] The working principle of this utility model is as follows:

[0039] First, the controller controls the lifting mechanism 1's top rod 11 to extend upwards by a set length. This set length should be greater than the minimum length required to trigger the alarm. For example, if the alarm is triggered when the metal cable 31 deviates 30 mm from its axial direction, then the top rod 11 of the lifting mechanism 1 should extend upwards by at least 30 mm. For instance, if the set length is 35 mm, and the top rod 11 has extended to 35 mm but the alarm still does not sound, it should be determined that the alarm system of the tension fence is malfunctioning. This should be reported immediately, and maintenance personnel should be dispatched for repairs. If the top rod 11 has extended to 35 mm and the alarm sounds, it should be determined that the alarm system of the tension fence is operating normally. In practice, tests can be set to be conducted 1 to 3 times per day, or even more frequently, to promptly detect and eliminate faults.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0041] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various changes or modifications within the scope of the claims, which do not affect the substantive content of this utility model.
