Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage power distribution cabinets, in particular to a GCK-type intelligent low-voltage power distribution cabinet based on automatic entry and exit and anti-falling of drawers. Background Art

[0002] In power systems, the GCK intelligent low-voltage distribution cabinet is an important distribution device. Its safety and reliability are crucial to the stable operation of the power system. However, the existing technology has some shortcomings in the drawer design of the distribution cabinet, especially in terms of anti-drop protection. Therefore, the GCK intelligent low-voltage distribution cabinet with anti-drop protection has appeared on the market.

[0003] For example, Chinese Patent Publication No. CN211930042U discloses a GCK low-voltage drawer-type distribution cabinet with an anti-fall mechanism. This existing device, when the cabinet door is opened, extends a spring to push a movable plate outward. The movable plate, restrained by the slider and the slide groove, prevents it from separating from the support plate. When the drawer is pulled out, a movable rod at the top of the movable plate supports the drawer, reducing the possibility of the drawer falling. However, this existing device still presents certain safety hazards in practical applications. On the one hand, the elastic force of the spring and the supporting force of the movable plate are often difficult to precisely control, causing the drawer to wobble or tilt due to uneven force during withdrawal or insertion, increasing the risk of the drawer falling. On the other hand, due to the limited contact area between the movable plate and the drawer and the relatively single support point, the drawer is prone to losing balance when subjected to external forces, further increasing the possibility of the drawer falling. Furthermore, when the drawer is pulled out, the lack of a position limiter makes it easy for the drawer to fall out of the distribution cabinet. Utility Model Content

[0031] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Example 1: Please refer to Figures 1-8 The utility model provides a technical solution: a GCK type intelligent low-voltage distribution cabinet based on automatic entry and exit and anti-fall of drawers, including a support base 1, an intelligent low-voltage distribution cabinet body 2 is arranged on the top of the support base 1, nine drawers 31 are slidingly arranged in the intelligent low-voltage distribution cabinet body 2, and a cabinet door 32 is hinged on the intelligent low-voltage distribution cabinet body 2.

[0033] Each drawer 31 corresponds to a cabinet door 32, and each cabinet door 32 is equipped with a control panel 33. This one-to-one correspondence between cabinet doors 32 and drawers 31, combined with the control panel 33 located outside the cabinet door 32, enables independent operation of multiple circuits. The operator can precisely control the opening and closing of the desired drawer 31 through the control panel 33, eliminating the risk of misoperation and simplifying the maintenance process of complex power distribution systems.

[0034] A slide groove 511 is provided in the cabinet body 2 of the intelligent low-voltage distribution cabinet. A movable plate 512 is slidably provided in the slide groove 511 . The top end of the movable plate 512 is fixedly connected to the bottom rear end of the drawer 31 .

[0035] The intelligent low-voltage power distribution cabinet body 2 is provided with a driving component 52 for driving the movable plate 512 to slide in the sliding groove 511 .

[0036] Furthermore, the driving assembly 52 includes a connection frame 521 fixed outside the intelligent low-voltage distribution cabinet body 2 and a screw rod 523 rotatably set in the slide groove 511.

[0037] A drive motor 522 is secured to the connecting frame 521. The output shaft of the drive motor 522 is in driving connection with one end of a screw rod 523. The other end of the screw rod 523 extends through the movable plate 512 and is threadedly connected thereto. The drive motor 522 is rigidly connected to the screw rod 523 via its output shaft, converting rotational motion into linear motion of the movable plate 512. This design replaces traditional manual push-pull methods, ensuring smooth and repeatable push-pull motion and positioning of the drawer 31 through the high-precision transmission characteristics of the screw rod 523.

[0038] Furthermore, the drive assembly 52 includes a control button 524 located on the outside of the cabinet door 32. This control button 524 is connected to the drive motor 522 for signal communication. The control button 524 on the outside of the cabinet door 32 and the internal control panel 33 form a dual access point. In an emergency, the operator can quickly activate the drive motor 522 using the nearest control button 524, significantly shortening emergency response time.

[0039] Furthermore, a connecting plate 532 is provided on the side of the drawer 31, and a strip groove 531 is provided in the intelligent low-voltage distribution cabinet body 2 for the connecting plate 532 to slide. The connecting plate 532 slides within the strip groove 531, providing bidirectional support for the drawer 31. The rigid guiding effect of the strip groove 531, combined with the limiting function of the connecting plate 532, effectively prevents the drawer 31 from drifting or tilting during movement.

[0040] Furthermore, both sets of connecting plates 532 are located at the rear end of the drawer 31. This centralized placement of the two connecting plates 532 at the rear end of the drawer 31 optimizes force distribution through the principle of leverage. This design reduces the number of moving parts while enhancing the balance of the front end of the drawer 31, preventing the risk of tipping due to a forward shift in the center of gravity.

[0041] Furthermore, mounting slots 541 are provided at the front and rear ends of the intelligent low-voltage distribution cabinet body 2 .

[0042] A first plunger-type travel switch 542 is provided in the installation groove 541 at the front end, and a second plunger-type travel switch 543 is provided in the installation groove 541 at the rear end.

[0043] The first plunger type limit switch 542 and the second plunger type limit switch 543 are both connected to the drive motor 522 for signal signals.

[0044] Furthermore, when the drawer 31 is in a closed state, the connecting plate 532 on its side is in contact with the second plunger-type travel switch 543 .

[0045] When the drawer 31 is open, the connecting plate 532 on its side abuts the first plunger-type limit switch 542. When the connecting plate 532 on the drawer 31 reaches its limit position, it physically abuts the first plunger-type limit switch 542 or the second plunger-type limit switch 543. This design replaces purely electronic detection with a mechanical trigger, avoiding false triggering caused by signal interference.

[0046] Example 2: Please refer to Figure 1-Figure 3 In combination with Example 1, it is further understood that ventilation grilles 4 are provided on the sides of the intelligent low-voltage distribution cabinet body 2. The ventilation grilles 4 on both sides of the intelligent low-voltage distribution cabinet body 2 form a continuous air convection channel. As the drawer 31 is pushed and pulled, the gap between the ventilation grilles 4 changes, further enhancing heat exchange efficiency and effectively reducing the operating temperature of the internal electrical components.

[0047] The GCK intelligent low-voltage power distribution cabinet operates as follows: When an operator needs to inspect or operate equipment within the cabinet body 2, they first issue a command via the control panel 33 on the outside of the cabinet door 32 or the independently located control button 524. Upon receiving the signal, the drive motor 522 activates, and its output shaft rotates the screw rod 523 within the chute 511. This causes the movable plate 512, which is threadedly engaged with the screw rod 523, to move linearly along the chute 511. Because the movable plate 512 is fixed to the bottom rear end of the drawer 31, this motion is directly translated into the drawer 31 being ejected, allowing the drawer 31 to slide smoothly out of the cabinet body 2.

[0048] During the movement of the drawer 31, the two sets of connecting plates 532 arranged at the rear end of the side thereof slide synchronously in the strip groove 531. This structure provides two-way support for the drawer 31 and ensures the vertical stability of the movement trajectory. When the drawer 31 is fully expanded to the working position, the front connecting plate 532 abuts against the second plunger-type limit switch 543 installed at the front end of the intelligent low-voltage distribution cabinet body 2, triggering the drive motor 522 to stop running immediately, preventing the drawer 31 from falling due to excessive outward movement. After the maintenance is completed, the operator starts the drive motor 522 again through the control device, and the screw rod 523 rotates in the opposite direction to drive the movable plate 512 to retract, and the drawer 31 then moves toward the inside of the intelligent low-voltage distribution cabinet body 2. When the drawer 31 is fully closed, the rear connecting plate 532 contacts the first plunger-type limit switch 542 at the rear end of the intelligent low-voltage distribution cabinet body 2, and the drive motor 522 stops again to ensure that the drawer 31 is accurately reset.

[0049] During operation, ventilation grilles 4 on both sides of the intelligent low-voltage distribution cabinet 2 continuously create air convection channels, assisting in dissipating heat from the internal electrical components. This device, through the linkage control of a screw drive mechanism and a limit switch, enables the electric push-pull operation of the drawer 31. This simplifies manual operation and effectively prevents the risk of the drawer 31 accidentally falling due to a mechanical limiter structure.

[0050] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
