Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Example 1, referring to Figure 1 - Figure 3 This is the first embodiment of the present invention, which provides a power distribution cabinet with insulation monitoring and safety interlock. The device includes: a power distribution cabinet 1, a locking unit 2 fixedly installed on the inner wall of the power distribution cabinet 1 for locking and unlocking the inside of the power distribution cabinet 1; an electrical device 3 fixedly installed on the inner wall of the power distribution cabinet 1 for normal operation inside the power distribution cabinet 1; and an insulation detector 4 fixedly installed on the inner wall of the power distribution cabinet 1, and the insulation detector 4 is fixedly connected to the electrical device 3 for real-time detection of the electrical device 3 inside the power distribution cabinet 1.

[0027] The locking unit 2 includes: a drive assembly 21 fixedly installed on the power distribution cabinet 1 for locking the power distribution cabinet 1; a locking assembly 22 fixedly installed on the drive assembly 21 for multi-functional unlocking of the power distribution cabinet 1; and a cabinet door assembly 23 slidably installed on the locking assembly 22, and the cabinet door assembly 23 is rotatably connected to the power distribution cabinet 1 for cooperating with the drive assembly 21 and the locking assembly 22 to complete the locking and unlocking operations.

[0028] During use, when the distribution cabinet 1 needs to be opened, the locking component 22 can be driven by the network control, which in turn cooperates with the drive component 21 to slide out of the cabinet door component 23, completing the network control unlocking. In the event of a network or power outage, the key is inserted into the drive component 21, which drives the locking component 22, causing it to slide out of the cabinet door component 23, completing the manual unlocking. At the same time, the insulation detector 4 connected to the electrical equipment 3 also monitors the electrical connection status inside the electrical equipment 3 in real time. This not only achieves quick locking and intelligent network control unlocking of the distribution cabinet 1, but also enables mechanical unlocking by key in the event of a power outage, power failure, or network control component failure. This solves the problem that existing distribution cabinets equipped with security network locks cannot be opened under special working conditions. It is convenient to operate and has a stable and reliable structure, which simplifies the switching process of the distribution cabinet 1, reduces the difficulty of operation and maintenance, and ensures the normal use of the equipment in various scenarios.

[0029] Example 2, refer to Figure 1 - Figure 6 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that the drive assembly 21 includes the following parts: a mounting shell 211 fixedly mounted on the distribution cabinet 1 for fixed connection to the distribution cabinet 1; a sliding groove 213 fixedly mounted on the inner wall of the mounting shell 211 for sliding with a T-block 214; a T-block 214 slidably mounted inside the sliding groove 213 for limiting the movement of the toothed plate 216; a toothed plate 216 fixedly mounted on the T-block 214 for meshing and driving gears 217 and 222; and a limiting member 215 fixedly mounted on the toothed plate 216, which is slidably connected to the mounting shell 211 and further cooperates with the T-block 214 to limit the movement of the toothed plate 216.

[0030] Compared to Embodiment 1, a support member 219 is further fixedly installed on the inner wall of the mounting shell 211 for rotating support of the gear 217; the gear 217 is rotatably mounted on the support member 219, and the gear 217 is meshed with the toothed plate 216 for driving the toothed plate 216 to mesh and move.

[0031] In addition, a key post 218 is fixedly installed on gear 217, and the key post 218 is rotatably connected to the support member 219 for rotating gear 217; a plug member 212 is fixedly installed on the mounting shell 211 for inserting into the U-shaped slot 232 for fixing.

[0032] Furthermore, the locking assembly 22 includes a drive member 221 fixedly installed on the inner wall of the mounting housing 211 for rotating the electric control gear 222; and a gear 222 rotatably installed on the output end of the drive member 221, wherein the gear 222 meshes with the gear plate 216 for moving the gear plate 216 while the electric control gear 222 rotates.

[0033] Furthermore, the bottom of gear 222 is meshed with a toothed plate 223, and the toothed plate 223 is slidably connected to the mounting shell 211 and the plug 212 for moving when gear 222 rotates; an adjusting member 224 is fixedly installed on the toothed plate 223, and the movement of the toothed plate 223 causes the locking block 226 to move as well; a pull rod 225 is rotatably installed on the adjusting member 224 for connecting the adjusting member 224 and the locking block 226.

[0034] In addition, a locking block 226 is rotatably installed on the other end of the pull rod 225, which is used to engage and lock with the U-shaped slot 232; a return spring 227 is fixedly installed on the locking block 226, and the locking block 226 is slidably connected to the plug 212, which is used to squeeze and retract the locking block 226 towards the middle when the toothed plate 223 moves.

[0035] Furthermore, the cabinet door assembly 23 includes a cabinet door body 231 rotatably mounted on the power distribution cabinet 1 for closing and opening the power distribution cabinet 1; and a U-shaped slot 232 fixedly mounted on the cabinet door body 231, wherein the U-shaped slot 232 is slidably connected to the plug 212 and slidably connected to the card block 226 for locking and unlocking in cooperation with the card block 226.

[0036] During use, when the power distribution cabinet 1 is in the closed state, it is unlocked through the network control system. At this time, by controlling the drive component 221, the drive component 221 drives the gear 222 to rotate. During the rotation of the gear 222, the gear plate 216 rotates to one side to engage, and the gear 217 also rotates synchronously inside the support component 219. Through the rotation of the gear 222, the meshing gear plate 223 begins to slide into the mounting shell 211, thereby causing the adjusting component 224 to move together. The pull rod 225 pulls the locking block 226 to retract into the plug component 212, and finally causes the locking block 226 to slide out of the U-shaped slot 232, completing the network control unlocking.

[0037] In the event of a power outage, inserting the key into the key post 218 and rotating it causes the gear 217 inside the support member 219 to rotate as well. Simultaneously, the gear plate 216 moves again with the cooperation of the T-block 214 and the limiting member 215. The gear plate 216 meshes with the gear 222 and rotates. The gear plate 223 also moves again under the meshing and rotation of the gear 222, causing the adjusting member 224 to drive the pull rod 225 to pull the locking block 226 out of the U-shaped slot 232 again, thus completing the manual unlocking. By employing both network-controlled and manual unlocking methods, the problem of existing power distribution cabinet 1 equipped with a security network lock being unable to be opened under special working conditions is solved. Its operation is convenient and its structure is stable and reliable. It simplifies the switching process of power distribution cabinet 1, reduces the difficulty of operation and maintenance, and ensures the normal use of the equipment in various scenarios. In addition, an insulation detector 4 is installed inside power distribution cabinet 1, which can effectively detect the internal circuit status in real time, effectively making up for the limitations of the existing equipment and significantly improving the practicality, reliability and adaptability of power distribution cabinet 1.

[0038] The remaining structure is the same as that in Example 1.
