Description

Technical Field

[0001] This utility model relates to the field of metal isolation mesh wall technology, specifically a metal isolation mesh wall with automatic alarm function. Background Technology

[0002] Isolation mesh is generally divided into guardrail mesh, protective mesh, fence mesh, highway guardrail mesh, railway guardrail mesh, railway protective fence, airport guardrail mesh, highway and municipal guardrail mesh, isolation fence, stadium fence, factory site guardrail mesh, wrought iron fence, iron horse, etc. In some special areas, isolation mesh is used to form isolation walls, and sensor alarm devices (infrared alarm, vibration alarm) are installed on the isolation walls for monitoring.

[0003] Chinese patent CN205637841U discloses a metal isolation fence with automatic alarm function. It uses a gravity sensor as an alarm activation device to monitor various phenomena involving gravity changes in the fence and can automatically send alarm signals in a timely manner to prevent illegal intrusion. This utility model has a low false alarm rate and does not require frequent personnel patrols, making it superior to existing infrared alarm and vibration alarm devices.

[0004] The aforementioned solution uses a suspension method to fix the mesh wall to the gravity sensor via connecting rods. However, because there is a certain space between the frame and the ground, and the mesh wall triggers an alarm based on changes in gravity, unauthorized personnel can place hard blocks between the frame and the ground to secure the mesh wall, thereby evading detection by the gravity sensor, posing a certain safety hazard. Therefore, we provide a metal isolation mesh wall with an automatic alarm function to solve the above problems. Utility Model Content

[0005] 1) Technical problems to be solved

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a metal isolation fence with an automatic alarm function.

[0007] (ii) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a metal isolation mesh wall with automatic alarm function, comprising:

[0009] The mounting bracket includes a mounting base, which has an installation cavity and an installation groove connected to each other. A weight sensor is installed in the installation cavity. Columns are fixedly connected to both sides of the mounting base, and limit grooves are provided on both columns.

[0010] The mesh wall structure includes a protective plate, the two ends of which are inserted into two limiting grooves, and the bottom end of which passes through the mounting groove and abuts against the weight sensor.

[0011] A fixing plate is detachably installed on the column, and the fixing plate is provided with connecting components for fixing the guard plate.

[0012] Furthermore, the mounting base is provided with multiple through holes, and an alarm is installed on the column, which is electrically connected to the weight sensor.

[0013] Furthermore, the protective plate is inlaid with an isolation mesh.

[0014] Furthermore, connecting plates are fixedly connected to both sides of the fixing plate, threaded holes are opened on the column, locking bolts are installed on the connecting plates, and one end of the locking bolt is threaded into the threaded hole.

[0015] Furthermore, a Y-shaped frame is fixedly connected to the fixing plate.

[0016] Furthermore, the connecting assembly includes a guide frame fixedly connected to the fixed plate, a linkage plate slidably connected inside the guide frame, an extension rod fixedly connected to the linkage plate, an assembly groove provided on the guard plate, the bottom end of the extension rod passing through the guide frame and the guard plate and extending into the assembly groove, and a fixing nut threadedly connected to the extension rod, and the fixing nut abutting against the inner wall of the assembly groove.

[0017] Furthermore, a spring is fitted onto the extension rod, and the two ends of the spring abut against the linkage plate and the guide frame, respectively.

[0018] (iii) Beneficial effects:

[0019] Compared with existing technologies, this metal isolation fence with automatic alarm function has the following advantages:

[0020] I. This utility model utilizes the coordinated arrangement of a fixed frame, a fixed plate, and connecting components, and employs a weight sensor to detect the weight of the mesh wall structure in real time. In the event of illegal intrusion, damage, or abnormalities in the mesh wall structure (such as climbing or dismantling), the weight sensor can quickly detect changes in gravity and promptly issue an alarm signal. Furthermore, when the protective plate is subjected to external forces, it can still generate a dynamic response that can be captured by the weight sensor, thereby effectively preventing attempts to evade detection by using hard supports.

[0021] II. This utility model forms a stable support structure through the fixed base and the column. The two ends of the guard plate are inserted into the limiting groove, and the bottom end abuts against the weight sensor, ensuring that the overall structure is firm and easy to disassemble and maintain. At the same time, the guard plate is linked with the fixed plate through the connecting component, which not only enhances the overall stability of the wire mesh wall, but also provides convenience for subsequent expansion and installation of additional protective measures such as barbed wire, thereby improving the protection level and scope of application.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-3 As shown, this utility model provides a technical solution: a metal isolation mesh wall with automatic alarm function, including a fixing frame, a mesh wall structure and a fixing plate 9.

[0028] The fixing frame includes a fixing base 1, on which a mounting cavity 2 and a mounting groove 4 are provided, and the mounting cavity 2 and the mounting groove 4 are connected. Both the mounting cavity 2 and the mounting groove 4 are horizontally connected grooves. A weight sensor 3 is installed in the mounting cavity 2. The weight sensor 3 is an existing structure that can detect the weight of the mesh wall structure itself and transmit a warning signal after a change in weight occurs.

[0029] Both sides of the fixed base 1 are fixedly connected with columns 5. Each column 5 has a limiting groove 6. The limiting groove 6 is connected to the mounting cavity 2 and the mounting groove 4. The columns 5 can be fixed to the fixed base 1 by welding. The fixed base 1 also has multiple through holes. An alarm is installed on the column 5. The alarm is electrically connected to the weight sensor 3. The through holes are used to discharge the liquid in the mounting cavity 2 and connect the weight sensor 3 to the alarm circuit. After the alarm signal is transmitted to the alarm, the alarm will emit a buzzing sound to warn the user.

[0030] The mesh wall structure includes a protective plate 7, with both ends of the protective plate 7 inserted into two limiting grooves 6. The bottom end of the protective plate 7 passes through the mounting groove 4 and abuts against the weight sensor 3. An isolation mesh 8 is embedded in the protective plate 7. When installing the protective plate 7, the bottom of the protective plate 7 is inserted into the mounting groove 4, and both ends of the protective plate 7 are respectively in the two limiting grooves 6.

[0031] The fixing plate 9 is detachably installed on the column 5. The fixing plate 9 is provided with a connecting component for fixing the guard plate 7. The fixing plate 9 is fixedly connected to the connecting plate 10 on both sides. The column 5 is provided with a threaded hole 12. The connecting plate 10 is provided with a locking bolt 11, and one end of the locking bolt 11 is threaded into the threaded hole 12.

[0032] After the protective plate 7 is installed, the bottom surface of the fixing plate 9 is placed against the two columns 5, and the connecting plate 10 is placed against the columns 5. The fixing plate 9 and the columns 5 are then connected by locking bolts 11 and threaded holes 12.

[0033] A Y-shaped frame 13 is fixedly connected to the fixed plate 9, which can install the barbed wire on the fixed plate 9 through the Y-shaped frame 13, thereby forming another shield above the fixed plate 9.

[0034] The connecting assembly includes a guide frame 15 fixedly connected to the fixed plate 9, a linkage plate 16 slidably connected inside the guide frame 15, an extension rod 17 fixedly connected to the linkage plate 16, an assembly groove 14 opened on the guard plate 7, the bottom end of the extension rod 17 passes through the guide frame 15 and the guard plate 7 and extends into the assembly groove 14, and a fixing nut 19 is threadedly connected to the extension rod 17, and the fixing nut 19 abuts against the inner wall of the assembly groove 14.

[0035] After fixing the fixing plate 9, insert the extension rod 17 into the assembly slot 14 and connect the extension rod 17 to the guard plate 7 by fixing the nut 19. When the guard plate 7 has longitudinal displacement, it will drive the linkage plate 16 to slide inside the guide frame 15.

[0036] A spring 18 is fitted on the extension rod 17, and the two ends of the spring 18 abut against the linkage plate 16 and the guide frame 15 respectively. The spring 18 on the extension rod 17 provides elastic support for the guard plate 7, so as to prevent the guard plate 7 from squeezing the weight sensor 3 too much.
