Description

Technical Field

[0001] This utility model relates to the technical field of remote opening and remote alarm devices for metering cabinets, specifically a remote locking and alarm device for an electricity metering cabinet. Background Technology

[0002] An electricity metering cabinet is a specialized cabinet for accurately measuring users' electricity consumption. By integrating devices such as electricity meters, current transformers, and voltage transformers, it measures and records parameters such as electricity consumption, voltage, and current, and serves as the core basis for electricity bill settlement between power companies and users.

[0003] For example, patent publication number "CN218728711U", entitled "A Remote Locking Device Based on Electrical Automation Control Cabinet", includes a PLC remote control cabinet body and a cabinet door. The cabinet door is hinged to the front facade of the PLC remote control cabinet body. The patent uses an inner frame, an outer frame, tempered glass, and a first electric push rod. The first electric push rod is remotely controlled through the PLC remote control cabinet body. During equipment operation, the operator can extend the first electric push rod through the PLC remote control cabinet body. The first electric push rod pushes the inner frame into the slot of the outer frame, sealing the control buttons located on the front facade of the cabinet door, thus blocking and locking the control buttons on the front facade of the cabinet door. This prevents accidents caused by operator misoperation during equipment operation and improves safety.

[0004] The aforementioned patent lacks direct and effective verification of the locking tongue's position during use, resulting in an inability to effectively identify the cabinet door's closed state. Therefore, a remote locking and alarm device for the power metering cabinet is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a remote locking and alarm device for an electricity metering cabinet to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a remote locking and alarm device for an electricity metering cabinet, comprising a cabinet body, a cabinet door rotatably connected inside the cabinet body, a locking component installed between the cabinet door and the cabinet body, a mutual inductance component installed between the cabinet door and the cabinet body, a control terminal electrically connected to the mutual inductance component, an alarm component electrically connected to the control terminal, a wireless communication device electrically connected to the control terminal, and the locking component and the control terminal electrically connected.

[0007] The mutual inductance assembly includes a first mutual inductance device and a second mutual inductance device. The first mutual inductance device includes an optical signal transmitter. The optical signal generator is fixedly installed on one side inside the cabinet. An optical signal receiver for receiving optical signals is fixedly connected to one side of the cabinet door. The optical signal transmitter and the control terminal are electrically connected. The optical signal receiver and the control terminal are also electrically connected.

[0008] Preferably, the locking assembly includes a first electric telescopic component, which is fixedly installed on one side of the cabinet door. A limiting rod is fixedly connected to the telescopic end of the first electric telescopic component. A limiting groove for matching the outer wall of the limiting rod is opened on one side inside the cabinet door. A light-shielding plate is fixedly connected to the outer wall of the limiting rod.

[0009] Preferably, the second mutual inductance device includes a first conductive component, which is fixedly installed on one side of the cabinet body, and the second conductive component is fixedly connected to one side of the cabinet body.

[0010] Preferably, a current detection device is provided between the first conductive component and the second conductive component for applying voltage and detecting whether there is current between the first conductive component and the second conductive component. The current detection device is electrically connected to the control terminal, and a connecting conductive component is fixedly connected to one side of the cabinet door.

[0012] Preferably, a first spring damper is fixedly connected inside the cabinet, and a compression block is fixedly connected to the telescopic end of the first spring damper.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The remote locking and alarm device for this energy metering cabinet, through the setting of mutual inductance components, when locked, connects the conductive parts to the first and second conductive parts, the current detection device identifies the current, and at the same time the light shield blocks the light signal, the light signal receiver has no signal, the dual signals confirm the locked state. When unlocked, the conductive parts separate, the current disappears, the limiting rod retracts and drives the light shield to move, the light signal is restored, and the cabinet door is clearly open, thus effectively identifying the cabinet door closed state.

[0015] Meanwhile, when "light signal recovery + current presence" is detected, the alarm component is triggered and the user is notified remotely, forming a safety closed loop of "status monitoring - anomaly identification - real-time alarm". The cabinet door can be remotely controlled to open and close via a wireless communication device, ensuring the convenience of the device. Attached Figure Description

[0020] 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.

[0021] like Figure 1 - Figure 3 As shown, this utility model provides a technical solution: a remote locking and alarm device for an electricity metering cabinet, including a cabinet body 1, a cabinet door 2 rotatably connected inside the cabinet body 1, a locking component 3 installed between the cabinet door 2 and the cabinet body 1, a mutual inductance component 4 installed between the cabinet door 2 and the cabinet body 1, a control terminal electrically connected to the mutual inductance component 4, an alarm component electrically connected to the control terminal, a wireless communication device electrically connected to the control terminal, and the locking component 3 electrically connected to the control terminal;

[0022] The mutual inductance assembly 4 includes a first mutual inductance device and a second mutual inductance device. The first mutual inductance device includes an optical signal transmitter 401. The optical signal transmitter 401 is fixedly installed on one side inside the cabinet 1. An optical signal receiver 402 for receiving optical signals is fixedly connected to one side of the cabinet door 2. The optical signal transmitter 401 is electrically connected to the control terminal, and the optical signal receiver 402 is electrically connected to the control terminal.

[0023] The locking assembly 3 includes a first electric telescopic component 301, which is fixedly installed on one side of the cabinet door 2. The telescopic end of the first electric telescopic component 301 is fixedly connected to a limiting rod 302. A limiting groove is provided on one side inside the cabinet door 2 to adapt to the outer wall of the limiting rod 302. A light shield 303 is fixedly connected to the outer wall of the limiting rod 302.

[0024] The second mutual inductor includes a first conductive component 403, which is fixedly installed on one side inside the cabinet 1, and a second conductive component 404 is fixedly connected to one side inside the cabinet 1.

[0025] A current detection device 406 is provided between the first conductive component 403 and the second conductive component 404 for applying voltage and detecting whether there is current between the first conductive component 403 and the second conductive component 404. The current detection device 406 is electrically connected to the control terminal. A connecting conductive component 405 is fixedly connected to one side of the cabinet door 2.

[0026] The control terminal is fixedly installed inside cabinet 1, and the alarm component is fixedly installed inside cabinet 1.

[0027] A first spring damper 5 is fixedly connected inside the cabinet 1, and a compression block 6 is fixedly connected to the telescopic end of the first spring damper 5.

[0028] The control terminal controls the extension and retraction of the telescopic end of the first electric telescopic component 301. When the telescopic end of the first electric telescopic component 301 extends, the limiting rod 302 moves, and contact is made between the outer wall of the limiting rod 302 and the inside of the limiting groove, thereby connecting the cabinet body 1 and the cabinet door 2, and thus closing the energy metering cabinet. When closed, the connecting conductive component 405 contacts the first conductive component 403 and the second conductive component 404. The connecting conductive component 405 allows current to pass between the first conductive component 403 and the second conductive component 404. At this time, the current detection device 406 can detect the current, and the control terminal will receive the signal from the current detection device 406. At the same time, since the light signal emitted by the light signal transmitter 401 is blocked by the light shield 303 on the limiting rod 302, the light signal receiver 402 will not receive the light signal. The control terminal will also receive the signal, thereby locking the energy metering cabinet, and judging whether the cabinet door 2 has been locked by the signal transmitted back by the mutual inductance component 4.

[0029] After cabinet door 2 is opened, the connecting conductive component 405 separates from conductive component 403 and conductive component 404 respectively. At this time, the telescopic end of the first electric telescopic component 301 retracts, and the limiting rod 302 and the light shield 303 move synchronously, allowing the light signal receiver 402 to receive the light signal. The control terminal analyzes the signal to determine that cabinet door 2 is open. If the light signal receiver 402 receives the light signal, the current detection device 406 will also receive the current and trigger an alarm. The control terminal controls the alarm component to activate the alarm. Simultaneously, the signal is transmitted remotely to the user terminal via a wireless communication device. When cabinet door 2 is opened, the first spring damper 5 applies elastic force to cabinet door 2 through the pressing block 6, thus facilitating the opening of cabinet door 2. With the mutual inductance component 4 in place, when locked, the connecting conductive component 405 contacts the first conductive component 403 and the second conductive component 404, and the current detection device 406 identifies the current. At the same time, the light shield 303 blocks the light signal, and the light signal receiver 402 receives no signal. The dual signals confirm the locked state. When unlocked, the conductive components separate, the current disappears, the limiting rod 302 retracts, and the light shield 303 moves, restoring the light signal and clearly indicating the open state of the cabinet door 2. This effectively identifies the closed state of the cabinet door 2. When "light signal restoration + current presence" is detected, the alarm component is triggered and the user is notified remotely, forming a safety closed loop of "status monitoring - anomaly identification - real-time alarm". Furthermore, the opening and closing of the cabinet door 2 can be remotely controlled via a wireless communication device, ensuring the convenience of the device.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
