Description

Technical Field

[0001] This utility model relates to the field of electrical control cabinet technology, and in particular to an anti-theft device for electrical control cabinets. Background Technology

[0002] As a critical control device in a power system, the electrical control cabinet must be designed in strict accordance with electrical wiring requirements, integrating switching equipment, measuring instruments, protective devices, and auxiliary equipment into a closed or semi-closed metal cabinet or panel. This layout must not only ensure the stability and reliability of the power system under normal operating conditions but also consider the convenience of maintenance and the safety of operators and surrounding equipment. The electrical control cabinet connects and disconnects circuits through manual or automatic switches. In case of faults or abnormalities, protective devices can quickly cut off the circuit or trigger an alarm mechanism, while measuring instruments display operating parameters in real time, providing decision-making support for maintenance personnel and allowing for necessary adjustments to electrical parameters to ensure the system is always in optimal working condition. It is widely used in various power applications, including power generation, distribution, and substation systems.

[0003] However, current electrical control cabinets still have significant shortcomings in terms of security. Most cabinets are only equipped with a single fixed-position camera for theft monitoring. This method of theft prevention can only serve as a means of post-incident investigation. Thieves may not even notice the presence of the camera, making it a weak deterrent. Thus, even if accountability can be pursued afterward, economic losses have already occurred. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide an anti-theft device for electrical control cabinets, so as to improve the deterrent effect and reduce the possibility of theft.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An anti-theft device for an electrical control cabinet includes a cabinet body. Doors are hinged to both sides of an operating opening on the side wall of the cabinet body. A limit frame is fixedly installed on the inner wall of the cabinet body at the operating opening. The limit frame and the inner wall of the cabinet body form a limit groove, which is adapted to the door. A proximity switch, a camera assembly, and a voice broadcast assembly are installed on the limit frame. When the door leaves the limit frame, the proximity switch activates the camera assembly and the voice broadcast assembly, and the voice broadcast assembly plays an anti-theft prompt.

[0007] Preferably, the voice broadcast component is an MP3 player, which is equipped with a rechargeable battery.

[0008] Preferably, the anti-theft prompts include warnings about anti-theft measures and warnings about the consequences of theft.

[0009] Preferably, the camera assembly includes a high-definition camera with night vision function disposed on the top of the limiting frame, and hidden pinhole cameras disposed on both sides of the limiting frame.

[0010] Preferably, the camera component is connected to a wireless transmission module, which communicates with external monitoring equipment via the Internet.

[0011] Preferably, the wireless transmission module is a 5G network communication module.

[0012] Preferably, the external monitoring device is one or more of a personal computer, smartphone, and tablet.

[0013] Preferably, the lens of the pinhole camera is provided with protective glass.

[0014] Preferably, the limiting frame is provided with an LED light on one side of the high-definition camera.

[0015] Preferably, the proximity switch is an inductive proximity switch with an adjustable detection distance.

[0016] This utility model has the following beneficial effects:

[0017] I. Enhanced Anti-theft Deterrence: Traditional electrical control cabinets are equipped with only a single fixed-position camera, offering little deterrent effect against thieves. This utility model's electrical control cabinet anti-theft device incorporates a voice broadcast component on the limit frame. When the cabinet door leaves the limit frame, the voice broadcast component plays anti-theft prompts, including warnings about anti-theft measures and the consequences of theft. This real-time voice warning directly deters thieves, making them aware of the potentially serious consequences of their actions, thus effectively reducing the likelihood of theft. Compared to traditional methods, this shifts from simply investigating after the fact to proactive deterrence, significantly improving the anti-theft security of the electrical control cabinet.

[0018] II. Comprehensive Monitoring and Recording: The camera system includes a high-definition camera with night vision capabilities mounted on top of the limiting frame, and hidden pinhole cameras on both sides of the limiting frame. The high-definition camera can clearly record the situation above and in front of the control cabinet's operating port, and its night vision function allows it to work normally at night. The hidden pinhole cameras are not easily detected by thieves and can record theft from different angles, avoiding the problem of blind spots caused by a single camera failing to fully record the theft process, and providing more comprehensive and accurate evidence for subsequent accountability.

[0019] III. Real-time Remote Monitoring: The camera module is connected to a wireless transmission module that communicates with external monitoring equipment via the internet. This module utilizes a 5G network, and the external monitoring equipment can be one or more personal computers, smartphones, or tablets. Leveraging the high speed and stability of 5G networks, the images captured by the camera module can be transmitted in real-time to these devices. This allows maintenance personnel to monitor the electrical control cabinet anytime, anywhere, without needing to be on-site, enabling them to promptly detect anomalies and take appropriate action, thus improving the timeliness and convenience of monitoring.

[0020] IV. Ensuring Normal Equipment Operation: The pinhole camera lens is equipped with protective glass to prevent dust, moisture, etc., from entering the lens, avoiding scratches or damage. This ensures the pinhole camera can operate stably for a long time, continuously providing clear monitoring images. An LED light is installed on one side of the high-definition camera within the limiting frame. In low-light conditions, the LED light provides sufficient illumination for the high-definition camera, ensuring clear visibility of the captured images and preventing lighting issues from affecting the monitoring effect. This guarantees the normal operation of the camera component in the entire anti-theft device.

[0021] V. Precise Detection and Flexible Adjustment: The proximity switch is an inductive proximity switch with an adjustable detection distance. The inductive proximity switch can accurately detect whether the cabinet door has left the limit frame. When the door moves to the set detection distance, the camera and voice broadcast components are activated promptly. The adjustable detection distance allows the anti-theft device to flexibly adjust the detection range of the proximity switch according to different usage scenarios and needs, improving the device's applicability and flexibility.

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] First embodiment

[0029] like Figures 1 to 2 As shown, an anti-theft device for an electrical control cabinet includes a cabinet body 1. Doors 101 are hinged to both sides of the operating opening on the side wall of the cabinet body 1. A limit frame 2 is fixedly installed on the inner wall of the cabinet body 1 at the operating opening. The limit frame 2 and the inner wall of the cabinet body 1 form a limit groove, which is adapted to the door 101. A proximity switch 3, a camera component, and a voice broadcast component 5 are installed on the limit frame 2. When the door 101 leaves the limit frame 2, the proximity switch 3 activates the camera component and the voice broadcast component 5, which plays an anti-theft prompt.

[0030] like Figures 1 to 2As shown, cabinet 1 is the main structure of the entire anti-theft device for the electrical control cabinet. Doors 101 are hinged to both sides of the operating opening on the side wall of cabinet 1. Under normal conditions, doors 101 are in the closed position, embedded in a limiting groove formed by a limiting frame 2 fixed to the inner wall of cabinet 1 at the operating opening and the inner wall of cabinet 1. At this time, doors 101 and limiting frame 2 are tightly fitted and in a relatively stable position. A proximity switch 3, a camera component, and a voice broadcast component 5 are installed on the limiting frame 2. When doors 101 are not removed from the limiting frame 2, these components are in standby mode and do not perform their respective functions. When theft occurs and doors 101 are opened and removed from the limiting frame 2, the relative position between doors 101 and the limiting frame 2 changes. At this time, the proximity switch 3 on the limiting frame 2 detects this change (the proximity switch 3 determines the state by sensing the distance between the object and the switch; it is triggered when doors 101 move a certain distance beyond its set detection range). When proximity switch 3 is triggered, it sends a start signal to voice broadcast component 5. Upon receiving the signal, voice broadcast component 5 begins operation, playing pre-set anti-theft prompts, including warnings about anti-theft measures and the consequences of theft, thus deterring thieves. Simultaneously, proximity switch 3 also sends a start signal to camera component, which begins operation, recording images of the area around the control cabinet's operating port to provide visual evidence for potential future incident investigations.

[0031] like Figures 1 to 2 As shown, the voice broadcast component 5 uses an MP3 player and is equipped with a rechargeable battery. The rechargeable battery provides continuous and stable power to the MP3 player, ensuring it can function normally when needed, eliminating the need for frequent battery replacements, thus improving ease of use and the device's sustainable operation. When the proximity switch 3 triggers the start signal, the MP3 player begins playing pre-stored anti-theft prompts, including warnings about anti-theft measures and the consequences of theft. By playing these warning messages in real time, potential thieves are psychologically deterred, making them aware of the potentially serious consequences of theft, thereby reducing the likelihood of theft.

[0032] like Figures 1 to 2 As shown, the camera assembly consists of a high-definition camera 401 with night vision capability mounted on top of the limiting frame 2 and hidden pinhole cameras 402 on both sides of the limiting frame 2. The high-definition camera 401 can clearly record the situation above and in front of the control cabinet's operating port. Its night vision function allows it to record normally at night or in low-light environments, ensuring all-weather monitoring. The hidden pinhole cameras 402 are difficult to detect and can record theft from different angles, avoiding the problem of blind spots caused by a single camera preventing the comprehensive acquisition of information about the theft process, and providing comprehensive and accurate video evidence for subsequent accountability.

[0033] The pinhole camera 402 has a protective glass at the lens, which can effectively block dust, moisture and other impurities from entering the lens, prevent the lens from being scratched or damaged, and ensure that the pinhole camera 402 can work stably for a long time and continuously provide clear monitoring images.

[0034] like Figures 1 to 2 As shown, the camera component is connected to a wireless transmission module 403, which communicates with an external monitoring device 404 via the Internet.

[0035] The wireless transmission module 403 uses a 5G network communication module, which features high speed, low latency, and large capacity. This allows the images captured by the camera component to be transmitted quickly and stably over the internet, ensuring the real-time performance and smoothness of the monitoring footage without any stuttering or delay.

[0036] The wireless transmission module 403 communicates with external monitoring devices 404 (one or more of a personal computer, smartphone, and tablet) via the internet. Maintenance personnel can use these external monitoring devices 404 to receive images transmitted from the camera components anytime, anywhere, enabling real-time remote monitoring of the electrical control cabinet. Once an anomaly is detected, appropriate measures can be taken promptly, improving the timeliness and convenience of monitoring.

[0037] The proximity switch 3 is an inductive proximity switch. It utilizes the fact that when a conductive object approaches the proximity switch 3, which generates an electromagnetic field, eddy currents are induced within the object. These eddy currents react with the proximity switch 3, causing changes in the internal circuit parameters, thereby detecting the presence or absence of a conductive object and controlling the switch's on / off state. Its detection distance is adjustable, allowing the anti-theft device to flexibly adjust the detection range of the proximity switch 3 according to different usage scenarios and actual needs. For example, in environments with larger spaces or varying requirements for detection accuracy, adjusting the detection distance ensures that the proximity switch 3 can accurately detect whether the door 101 has left the limit frame 2, and promptly trigger the camera component and voice broadcast component 5, improving the device's applicability and flexibility.

[0038] Second embodiment

[0039] like Figure 3 As shown, the limiting frame 2 has an LED light 405 installed on one side of the high-definition camera 401. In the actual environment where the electrical control cabinet is located, there may be insufficient light, such as at night, in basements or other poorly lit scenes, or in rainy weather when natural light is weak. When the cabinet door 101 is opened and the proximity switch 3 is triggered, and the high-definition camera 401 starts working, if the ambient light is too dark, the image captured by the camera will be blurry, noisy, and lack detail, making it impossible to accurately record key information about the theft, affecting the monitoring effect and subsequent accountability work.

[0040] An LED light 405, mounted on one side of the high-definition camera 401, activates synchronously with the camera 401 after the cabinet door 101 leaves the limiting frame 2 and triggers the proximity switch 3. The LED light 405 emits bright and stable light, directly illuminating the area around the control cabinet's operating port, providing ample light compensation for the high-definition camera 401's recording. Through the supplementary lighting provided by the LED light 405, the high-definition camera 401 can still capture clear, highly color-accurate, and detailed images even in low-light conditions. This ensures that crucial information, such as the thief's physical characteristics, actions, and changes in the status of equipment inside the control cabinet, can be accurately recorded, providing strong and reliable video evidence for subsequent security management and incident investigation, effectively improving the monitoring efficiency of the entire anti-theft device under different lighting conditions.

[0041] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
