Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a low-voltage power distribution cabinet with anti-theft alarm function. Background Technology

[0002] Because power distribution cabinets contain precision electrical components and metal casings, they are often targeted by thieves. Cases of complete theft and violent dismantling are frequent, causing not only direct economic losses but also a chain of risks such as power outages and equipment failures.

[0003] Existing low-voltage distribution cabinets with anti-theft alarm functions still have significant limitations in their protection methods. To facilitate the relocation of distribution cabinets, they are usually installed in specific locations using a detachable installation method. Traditional distribution cabinets are mostly fixed directly to the ground with anchor bolts or limited by simple metal frames. The exposed fixing structure of such designs is easily damaged by thieves' tools. Bolts and frames can be pried open with crowbars, making them difficult to withstand strong dismantling by multiple people working together or mechanical tools. Some outdoor distribution cabinets are not even equipped with effective fixing devices and rely solely on their own weight to prevent movement. When thieves use tools such as crowbars and jacks to lift them, there is a high risk of overall displacement and theft. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a low-voltage distribution cabinet with an anti-theft alarm function. It solves the technical problem that existing technologies use simple metal frames and bolts for fixing and limiting, making the exposed fixing structure vulnerable to damage by thieves. Bolts and frames can be pried open with crowbars, making it difficult to withstand strong dismantling by multiple people or mechanical tools, and posing a high risk of overall displacement and theft. This new design achieves the goal of both directly preventing theft through physical fixing and promptly detecting potential risks through dynamic monitoring, reducing the risk of the entire distribution cabinet being stolen, and providing more comprehensive and reliable anti-theft protection for the distribution cabinet.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a low-voltage distribution cabinet with anti-theft alarm function, including a distribution cabinet body set on the top of the ground, mounting parts connected to the ground are fixedly installed on the four corner outer walls of the distribution cabinet body, an anti-theft frame is set in the recessed area of ​​the ground, an anti-theft component is set inside the anti-theft frame, a limit frame is fixedly installed on the inner top of the anti-theft frame, and a fixed base with a limit plugged into the limit frame is fixedly installed on the bottom of the distribution cabinet body; The anti-theft component includes an alarm fixedly installed on the top of the main body of the distribution cabinet, and a locking rod slidably connected to both sides of the limiting frame to fix the limiting frame and the fixed base. Pressure springs are fixedly installed at the four corners of the bottom of the limiting frame. A limiting plate that contacts the fixed base is fixedly installed on the top of the pressure spring. A control button that is electrically connected to the alarm is provided at the bottom of the limiting plate. The control button is disconnected to trigger the alarm by the deformation of the pressure spring.

[0006] Preferably, a support base for supporting the fixed base is fixedly installed at the inner bottom of the limiting frame, and the top end face of the support base is lower than the top end face of the limiting plate.

[0007] Preferably, a trigger that contacts the control button and cuts off power is fixedly installed at the bottom of the limiting plate.

[0008] Preferably, each of the four inner bottom corners of the limiting frame is fixedly installed with a support column located inside the pressure spring, and the control button is fixedly installed on the top of the support column.

[0009] Preferably, the multiple sets of locking rods on both sides are evenly distributed along the length of the fixed base, and the outer walls of the multiple sets of locking rods on each side are fixedly connected by a set of fixing plates.

[0010] Preferably, a fixed frame is fixedly installed at the bottom of the limiting frame, and a bidirectional screw is rotatably connected inside the fixed frame to drive the locking rods on both sides to move and is inserted into the fixed base. A rotary motor that drives the bidirectional screw to rotate is fixedly installed on the outer peripheral wall of the fixed frame.

[0011] Preferably, the outer peripheral walls on both sides of the bidirectional screw are threaded with driving components that are slidably connected to the fixed frame, and the top of the driving component passes through the fixed frame and is fixedly connected to the fixed plate.

[0012] By employing the above technical solution, this utility model provides a low-voltage distribution cabinet with anti-theft alarm function, which has at least the following beneficial effects: 1. This utility model installs a fixed base at the bottom of the distribution cabinet and a hidden anti-theft component below the ground. The anti-theft component combines mechanical fixing with dynamic monitoring to form a dual anti-theft system. The combination of the two forms an active defense plus passive alarm anti-theft measure. It can directly prevent theft through physical fixing and timely detect potential risks through dynamic monitoring, reducing the risk of the distribution cabinet being stolen as a whole. It provides more comprehensive and reliable anti-theft protection for distribution cabinets, and is especially suitable for the security protection of distribution cabinets in unattended and high-risk scenarios.

[0013] 2. This utility model uses the deformation of multiple sets of pressure springs to trigger the control switch, avoiding false alarms caused by minor collisions, environmental vibrations, or normal maintenance operations. The pressure spring triggering mechanism is specifically designed to address the core theft behavior of the distribution cabinet being lifted or moved as a whole. This design can accurately distinguish between normal operation and illegal handling, avoiding false alarms caused by non-theft behaviors such as slight shaking of the cabinet or external impact, thus improving the reliability of the anti-theft system.

Detailed Implementation

[0017] 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.

[0018] Example 1 Based on existing technologies that use simple metal frames and bolts for fixing and limiting, the exposed fixing structure of this type of design is easily damaged by thieves' tools. Bolts and frames can be pried open with crowbars, making it difficult to withstand forceful dismantling by multiple people or mechanical tools. This poses a significant risk of the entire cabinet shifting and being stolen. This embodiment provides a low-voltage distribution cabinet with an anti-theft alarm function. It can directly prevent theft through physical fixing and also detect potential risks in a timely manner through dynamic monitoring, reducing the risk of the entire distribution cabinet being stolen and providing more comprehensive and reliable anti-theft protection. Please refer to... Figure 1 - Figure 5 The low-voltage distribution cabinet with anti-theft alarm function includes a main body 1 installed on the top of the ground. Mounting parts 11 connected to the ground are fixedly installed on the four corners of the outer wall of the main body 1. An anti-theft frame 2 is set in the recessed area of ​​the ground. An anti-theft component 3 is set inside the anti-theft frame 2. A limit frame 4 is fixedly installed on the inner top of the anti-theft frame 2. A fixed base 5 with a limit plug is fixedly installed at the bottom of the main body 1 and inserted into the limit frame 4. During use, the fixed base 5 is fixedly locked inside the limit frame 4, which can increase the risk of the main body 1 being stolen. At the same time, the possibility of the main body 1 being stolen can be further increased by setting multiple sets of pressure springs 33.

[0019] To facilitate the relocation of distribution cabinets, existing distribution cabinets are typically designed as a single unit for easy transport. However, when installing these cabinets in locations requiring power distribution, traditional physical protection methods, such as anchor bolt fixation, are prone to failure due to insecure installation or bolt damage. Furthermore, the exposed components make the cabinet body vulnerable to theft. By employing concealed anti-theft components, the risk of theft can be reduced. Figure 1 - Figure 4 As shown, the anti-theft component 3 includes an alarm 31 fixedly installed on the top of the main body 1 of the power distribution cabinet. The alarm 31 is also connected to the relevant management personnel's equipment via the Internet of Things to remind relevant personnel to take corresponding measures. It also includes a locking rod 32 that is slidably connected to both sides of the limit frame 4 to fix the limit frame 4 and the fixed base 5. Pressure springs 33 are fixedly installed at the four corners of the bottom of the limit frame 4. A limit plate 34 that contacts the fixed base 5 is fixedly installed on the top of the pressure spring 33. A control button 35 that is electrically connected to the alarm 31 is provided at the bottom of the limit plate 34. The control button 35 is deactivated by the deformation of the pressure spring 33. Before the main body 1 of the power distribution cabinet is installed, the alarm 31 is in a non-working state. When the fixed base 5 at the bottom of the main body 1 of the power distribution cabinet is installed inside the limit frame 4, the administrator connects the alarm 31 to the network to prevent the alarm 31 from being in a continuous whistling state when the main body 1 of the power distribution cabinet is not installed.

[0020] Since the pressure of gravity applied to the main body 1 of the distribution cabinet after installation is required to deform the pressure spring 33 to cut off the power to the alarm 31, and the stability of the support for the main body 1 of the distribution cabinet needs to be ensured, the top of the support base 6 is now lower than the top of the top limiting plate 34 of the pressure spring 33, such as... Figure 4 As shown, a support base 6 is fixedly installed at the bottom of the inner side of the limiting frame 4 to support the fixed base 5. The top end face of the support base 6 is lower than the top end face of the limiting plate 34. When the main body of the power distribution cabinet 1 is not installed inside the limiting frame 4, multiple sets of pressure springs 33 are in the open state. The top of the limiting plate 34 is higher than the top of the support base 6. When the main body of the power distribution cabinet 1 is supported on the top of the support base 6, the weight of the main body of the power distribution cabinet 1 deforms the multiple sets of pressure springs 33, thereby enabling the trigger 36 at the bottom to contact the control button 35. The control button 35 controls the alarm 31 to cut off the power.

[0021] Since any anti-theft measure can be cracked, when a thief accidentally steals the password of the control locking lever 32, causing multiple locking levers 32 to become ineffective, the cabinet's displacement is no longer directly restricted by the mechanical structure. The bottom of the limit plate 34 is fixedly equipped with a trigger 36 that contacts the control button 35 to cut off power. The four corners of the bottom of the limit frame 4 are all fixedly equipped with support columns 351 located inside the pressure spring 33. The control button 35 is fixedly installed on the top of the support column 351. When a thief attempts to lift or move the distribution cabinet (causing the distribution cabinet to separate from the spring or the pressure to drop suddenly), the pressure spring 33 will restore its deformation, separate from the control button 35, disconnect the switch, and trigger the alarm. Even if the cabinet is not completely moved, and only a brief lifting occurs, such as prying the cabinet so that the bottom is off the ground, the slight change in the spring deformation can be detected, achieving early warning and preventing further theft.

[0022] Example 2 Based on Example 1, such as Figure 3 - Figure 6 As shown, the device is also equipped with a locking rod 32 that is easy to insert into the fixed base 5, which firmly fixes the bottom of the main body 1 of the power distribution cabinet and hides it inside the underground anti-theft frame 2. Multiple sets of locking rods 32 are evenly distributed along the length of the fixed base 5 on both sides, and the outer walls of multiple sets of locking rods 32 on each side are fixedly connected by a set of fixing plates 321. The multiple sets of locking rods 32 are inserted into the fixed base 5, which firmly locks the bottom of the power distribution cabinet in the limiting frame 4 in the ground recess. The mechanical structure directly restricts the displacement of the cabinet, increasing the difficulty of theft from the source. Thieves need to destroy the locking rods 32 or the limiting frame 4 before they can carry out the move, which takes a long time, thus buying time for subsequent intervention.

[0023] A fixed frame 7 is fixedly installed at the bottom of the limiting frame 4. A bidirectional screw 9 is rotatably connected inside the fixed frame 7, which drives the locking rods 32 on both sides to move and is inserted into the fixed base 5. A rotary motor 8 that drives the bidirectional screw 9 to rotate is fixedly installed on the outer peripheral wall of the fixed frame 7. A drive component 10 that is slidably connected to the fixed frame 7 is threaded onto the outer peripheral wall of both sides of the bidirectional screw 9. The top of the drive component 10 passes through the fixed frame 7 and is fixedly connected to the fixed plate 321. The control button of the rotary motor 8 is operated by the management personnel. The output end of the rotary motor 8 is fixedly connected to the bidirectional screw 9. When the rotary motor 8 is working, the drive components 10 on both sides drive the fixed plates 321 on both sides to slide closer to each other, thereby driving multiple sets of locking rods 32 to be inserted into the fixed base 5 to lock the main body 1 of the power distribution cabinet.
