AI Technical Summary
The locking mechanism of traditional grounding management cabinets needs to be executed separately from the grounding wire retrieval and placement operations. This creates a gap in the operation logic, making it impossible to detect and correct any missing locking mechanisms, which poses a risk of misoperation. This could lead to safety accidents, especially during emergency or continuous operations.
By employing a sloping slider and spring reset device, combined with motor drive, threaded transmission and timing reset module, the ground wire is plugged in to trigger the lockout. The timer ensures that the locking lever automatically resets within a preset time, forming a complete control chain of "plug in → trigger lockout → timeout self-reset" to prevent lockout omission.
It effectively prevents interlock failure caused by operators forgetting to lock the interlock, reduces electrical misoperation, ensures the safety of power grid equipment and personnel, and improves the reliability and safety of operation.

Description
Technical Field
[0001] This utility model relates to the field of grounding management cabinet technology, and in particular to a grounding management cabinet that prevents misoperation. Background Technology
[0002] Traditional grounding management cabinets mainly consist of a cabinet body, partitions, and grounding wire storage compartments. Their locking function relies on mechanical latches or manual knobs. Operators need to manually trigger the locking mechanism (such as rotating the latch or moving the locking plate) to fix the grounding terminal after taking or placing the grounding wire. Although some improved devices have added physical limit structures, manual intervention is still required to complete the locking operation, and there is a lack of an active monitoring mechanism for the locking status. The core control logic of such devices is entirely based on the operator's self-awareness.
[0003] Power work sites are often complex environments (e.g., under pressure from emergency repairs, multiple tasks running concurrently), and operators are prone to forgetting interlocking procedures due to fatigue or negligence. More importantly, the existing interlocking mechanisms require separate execution of the interlocking action from the ground wire handling operation, resulting in a logical gap in operation. Once an interlock is missed, the system cannot detect and correct it autonomously. These deficiencies are particularly prominent in the following operating conditions: In emergency operations: Operators rush to work in order to shorten the power outage time, and the locking procedure is skipped; During continuous operation: Frequent removal and placement of ground wires leads to operational inertia, and single interlocking omissions cannot be detected in time; The above problems directly lead to the accumulation of interlocking failure risks: uninterlocked grounding terminals may fall off during cabinet door vibration or handling, causing grounding wire to be pulled out or interlocking failure accidents; in high-voltage electrical systems, such misoperation may cause serious accidents such as closing the circuit with the grounding wire connected or accidentally entering a live compartment, seriously threatening the safety of power grid equipment and personnel.
[0004] Therefore, to address the aforementioned issues, a ground wire management cabinet designed to prevent misoperation is proposed. This cabinet utilizes a sloping slider and spring reset device to implement a mandatory interlocking mechanism triggered upon ground wire insertion, eliminating the risk of human error. By integrating a motor drive, threaded transmission, and timing reset module, a complete control chain of "insertion in place → trigger locking → timeout self-reset" is established. This prevents interlocking failures caused by operators forgetting to lock after removing or placing the ground wire, reducing electrical misoperation and ensuring the safe and reliable operation of the unit. Utility Model Content
[0005] To overcome the problems that exist in the daily use of traditional grounding management cabinets, where the locking action of the existing grounding management cabinet's locking mechanism needs to be executed separately from the grounding wire retrieval and placement operations, resulting in a break in the operation logic; and that the system cannot automatically detect and correct any missed locking, the problem is that the locking mechanism of the existing grounding management cabinet needs to be executed separately from the grounding wire retrieval and placement operations, resulting in a break in the operation logic; and that the system cannot automatically detect and correct any missed locking.
[0006] The technical solution of this utility model is as follows: a ground wire management cabinet to prevent misoperation, comprising a cabinet body, a partition plate, a ground wire main body, a locking component, a connecting component, a control component, a support component, and an identification component. A partition plate is provided on the inner side of the cabinet body, and the ground wire main body is also provided on the inner side of the cabinet body. A locking component is provided on one side of the partition plate, and two sets of locking components are provided, located on opposite sides of the partition plate. A connecting component is provided on the inner side of the cabinet body, and a control component is provided on the inner side of the cabinet body.

The timer has a card holder on one side of the partition plate, a locking accessory on one end of the ground wire body, a slotted structure on the side of the locking accessory, a fixing plate below the card holder, a telescopic rod on one side of the fixing plate, a slider on one end of the telescopic rod, a beveled structure on one side of the slider, a spring on the outside of the telescopic rod, with the two ends of the spring connected to the slider and the fixing plate respectively, a trigger block on one side of the slider, a contact button on one side of the fixing plate, a motor on one side of the card holder, a threaded rod at the output end of the motor, a moving block on the outside of the threaded rod, the moving block and the threaded rod being threadedly connected, a locking rod on one side of the moving block, a slotted structure corresponding to the locking rod on the side of the card holder, and a timer on one side of the motor.
[0007] Preferably, by inserting the locking accessory at one end of the ground wire body into the card holder, with one end of the locking accessory contacting the inclined surface of the slider, the slider moves linearly along the direction of the telescopic rod. A spring is used to reset the slider position. The linear movement of the slider drives the trigger block to move linearly.

[0014] The beneficial effects of this utility model are: By inserting the locking accessory at one end of the ground wire body into the card slot, and having one end of the locking accessory in contact with the inclined surface of the slider, the slider moves linearly along the direction of the telescopic rod. The spring is used to reset the slider position. The linear movement of the slider drives the trigger block to move linearly. Pressing the contact button by the linear movement of the trigger block starts the motor. The motor drives the threaded rod to rotate. The rotation of the threaded rod drives the moving block to move linearly. The linear movement of the moving block drives the locking rod to move linearly. The locking rod moves linearly and embeds into the slot structure of the locking accessory, locking the ground wire body. A timer is used to preset the retraction time of the locking rod. When the retraction time of the locking rod exceeds the preset value of the timer, the motor is started to drive the threaded rod to rotate and reset the locking rod to the locked position, thereby preventing the locking failure caused by the operator forgetting to lock after picking up or putting down the ground wire.
