Description

Technical Field

[0001] This utility model belongs to the field of intelligent lock technology for power control cabinets, and specifically relates to an intelligent locking device for power system control cabinets. Background Technology

[0002] In existing power systems, the anti-misoperation interlocking function of control cabinet locking devices is a crucial element in ensuring equipment safety and operational compliance. However, when the anti-misoperation interlocking fails due to mechanical or electrical malfunctions, maintenance personnel are often forced to use master keys for unlocking. While this emergency measure can temporarily solve the problem, it poses several hidden dangers. First, manual unlocking with a master key lacks necessary logical verification, potentially leading to the erroneous unlocking of non-target equipment and causing operational errors. Second, relying on human judgment is susceptible to the influence of operator experience and condition, increasing safety risks. The root cause of these problems lies in the limitations of traditional mechanical interlocking systems and the lack of standardized management of emergency unlocking mechanisms. Conventional solutions include strengthening operator training, improving unlocking approval processes, and adding double checks after unlocking. However, while these methods can reduce risks to some extent, they cannot fundamentally eliminate misoperation, and the cumbersome procedures may delay processing time and even cause greater economic losses. Therefore, we aim to design a novel intelligent locking device for power system control cabinets to address this issue. Utility Model Content

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.

[0024] As the first embodiment of this utility model:

[0025] Please see Figures 1 to 5 A smart locking device for a power system control cabinet includes: a control cabinet body 100, an electronic lock assembly 200 for locking the cabinet door installed at the cabinet door position of the control cabinet body 100, and a barcode scanning module 120 for providing a static QR code installed on the front surface of the front cabinet door of the control cabinet body 100.

[0026] The electronic lock assembly 200 includes a tongue sleeve 210 and a lock body 220. The tongue sleeve 210 is installed on the door frame of the control cabinet body 100, and the lock body 220 is installed on the cabinet door of the control cabinet body 100 near the tongue sleeve 210. In actual use, a Hall sensor is installed inside the tongue sleeve 210 to detect the position of the lock tongue 223 in real time and feed it back to the main control chip. At the same time, an anti-pry sensor is installed inside the lock body 220 to cut off the motor power supply when there is abnormal vibration, trigger a local alarm and push a mobile phone notification. When the network / power is cut off, Bluetooth communication is automatically switched or the backup mechanical key is used to open the mechanical lock 110.

[0027] The control cabinet body 100 has a latch outlet 130 on one side of the cabinet door where the lock body 220 is installed for the latch 223 to enter and exit. The latch outlet 130 is directly opposite the latch sleeve 210, and the latch sleeve 210 has a latch insertion port near the latch outlet 130 for the latch 223 to enter the interior of the latch sleeve 210.

[0028] The lock body 220 includes a lock box 221, inside which a lock cylinder 222 is installed. A lock tongue 223 is installed at the end of the lock cylinder 222 near the tongue sleeve 210. The size and structure of the lock tongue 223 match the size and structure of the lock tongue insertion opening on the tongue sleeve 210.

[0029] The lock body 220 has a rotating component 224 installed inside for driving the bolt 223 to rotate. It includes a gear set and a micro motor. The output shaft of the micro motor is connected to the gear set for transmission. The end of the gear set near the bolt 223 is fixedly connected to the bolt 223 through a rotating shaft.

[0030] A static QR code is embedded and fixed on the front surface of the scanning module 120, and a transparent glass plate is fixed on the front surface of the scanning module 120.

[0031] The lock body 220 is equipped with a control board with a main control chip. The main control chip interacts with the cloud server through a WiFi / 4G module to complete remote authorization. In actual use, the lock head 222 and the rotating part 224 can move inside the lock box 221, thereby allowing the lock tongue 223 to move freely in and out of the lock. An electromagnetic block and a matching spring are installed inside the lock box 221 to adjust the movement of the lock head 222 and the rotating part 224 inside the lock box 221.

[0033] Specifically, by setting up a barcode scanning module 120, in conjunction with the electronic lock assembly 200 installed on the control cabinet body 100, the main control chip installed inside the module works in conjunction with the barcode scanning module 120. In actual use, the user scans the QR code on the barcode scanning module 120 with their mobile phone. The built-in software on the mobile phone scans the static QR code on the barcode scanning module 120 and reads the encrypted data (after scanning the static QR code, the information of the control cabinet body 100 can also be read to facilitate the operator to confirm whether the control cabinet body 100 needs to be opened). Then, a cloud verification signal is sent to the main control chip via WiFi / 4G. After receiving the verification signal and completing the verification, the main control chip controls the current of the dry cell battery to move to the lock body 220, thereby driving the micro motor to start. This enables the electronic lock assembly 200 to be unlocked and locked, realizing the purpose of intelligently locking the control cabinet body 100. This effectively solves the problem that manual unlocking with a master key may lead to the wrong unlocking of non-target devices due to the lack of necessary logical verification, thus causing misoperation accidents. It fundamentally eliminates misoperation and simplifies the operation process to avoid delays in processing time.

[0034] As a second embodiment of this utility model:

[0035] Please see Figures 1 to 5 The lock body 220 also has a Bluetooth module installed inside to support offline temporary unlocking command transmission.

[0036] Based on the first embodiment described above, further, by installing a Bluetooth module inside the lock body 220, in actual use, if a power outage, network outage, or forgetting to bring the key to the mechanical lock 110 occurs, the user can use the Bluetooth module built into the lock body 220 to transmit an offline temporary unlocking command. After transmitting the unlocking command using the Bluetooth module, the micro motor is activated, thereby realizing unlocking or locking, avoiding the problem of not being able to open the cabinet door in the event of a power outage, network outage, or forgetting to bring the key to the mechanical lock 110.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
