[0018] 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.

[0019] Reference Figure 1 This utility model provides an embodiment of an electrical engineering distribution cabinet, including a cabinet body 1. The cabinet body 1 serves as the main frame of the distribution cabinet, carrying internal electrical equipment and components. A cabinet door 3 is rotatably connected to the front side of the cabinet body 1. The cabinet door 3 can rotate around the front side of the cabinet body 1 to realize the opening and closing of the interior of the cabinet body 1, which facilitates equipment maintenance and operation. An observation window 4 is provided on the inner wall of the cabinet door 3. The observation window 4 is made of transparent glass, which allows observation of the operating status of the equipment inside the cabinet body 1 without opening the cabinet door 3. The observation window 4 is made of transparent glass.

[0020] Reference Figures 2-4An installation strip 5 is fixedly connected to the inner wall of the cabinet 1. The installation strip 5 is fixed to the inner wall of the cabinet 1, providing a support structure for the installation and positioning of the mounting plate 6. Two symmetrical installation strips 5 are provided, symmetrically distributed on both sides of the inner wall of the cabinet 1, ensuring the balance and stability of the mounting plate 6 during installation. Multiple slots are evenly distributed on the inner wall of the installation strip 5, along the length of the installation strip 5, facilitating adjustment of the installation height of the mounting plate 6 to adapt to the installation requirements of different equipment. The dimensions of the slots in the installation strip 5 are the same as the cross-sectional dimensions of the locking block 10. The card slot and the card block 10 are sized to match, ensuring that the card block 10 can be stably inserted into the card slot, thereby limiting and fixing the mounting plate 6. A fixing post 11 is fixedly connected to the inner wall of the cabinet 1. The fixing post 11 is fixed to the inner wall of the cabinet 1 to provide guidance for the sliding of the mounting plate 6 and ensure the straightness of the mounting plate 6 when it moves. The mounting plate 6 is slidably connected to the outer wall of the fixing post 11. The mounting plate 6 can slide along the fixing post 11 and is used to install electrical equipment. It is the support platform for the equipment. A limiting post 7 is fixedly connected to the rear side of the mounting plate 6. The limiting post 7 is fixed to the rear of the mounting plate 6. On the side, the sliding of the movable plate 9 is limited to prevent it from shifting. The movable plate 9 is elastically connected to the rear side of the mounting plate 6 via a spring 8. The spring 8 connects the mounting plate 6 and the movable plate 9, providing elastic restoring force to the movable plate 9, facilitating the engagement and disengagement of the locking block 10. The movable plate 9 passes through and is slidably connected to the outer wall of the limiting post 7. One end of the spring 8 is fixedly connected to the rear side of the mounting plate 6, and the other end is fixedly connected to the front side of the movable plate 9. The locking block 10 is fixedly connected to the front side of the movable plate 9. On the side, it cooperates with the slot of the mounting strip 5 to realize the fixed positioning of the mounting plate 6. The outer wall of the locking block 10 is locked onto the inner wall of the mounting plate 6. There are two locking blocks 10, and the two locking blocks 10 correspond to the slots of the mounting strips 5 on both sides respectively to ensure that the force on both sides of the mounting plate 6 is balanced. The two locking blocks 10 are symmetrically arranged. A ventilation component 2 is provided on the inner wall of the right side of the cabinet 1. The ventilation component 2 is installed on the inner walls of both sides of the cabinet 1 to realize ventilation and air exchange inside the cabinet 1, reduce the temperature, and ensure the normal operation of electrical equipment. The ventilation component 2 is used for ventilation of the distribution cabinet.

[0021] Reference Figure 1 and Figure 5The ventilation component 2 includes an isolation barrier 21, which is fixed to the inner wall of the cabinet 1 to prevent larger debris from entering the cabinet 1, providing initial protection. The isolation barrier 21 is fixedly connected to the inner wall of the cabinet 1. A fixing plate 25 is fixedly connected to the inner wall of the cabinet 1, providing mounting support for the motor 26 and ensuring stable installation. The motor 26 is fixedly connected to the left side of the fixing plate 25, providing power for the rotation of the shaft 22. A filter plate 24 is fixedly connected to the inner wall of the cabinet 1, filtering dust and other impurities from the air entering the cabinet 1 to ensure adequate air intake. For cleaning, a rotating shaft 22 is rotatably connected through the inner wall of the filter plate 24. The rotating shaft 22 passes through the filter plate 24 and can rotate, providing a mounting carrier for the cleaning strip 23 and transmitting power to the motor 26. The cleaning strip 23 is fixedly connected to the outer wall of the rotating shaft 22. The cleaning strip 23 is fixed to the outer wall of the rotating shaft 22 and rotates with the rotating shaft 22 to clean the dust on the surface of the filter plate 24, preventing the filter plate 24 from clogging and ensuring ventilation efficiency. There are two cleaning strips 23. The two cleaning strips 23 clean both sides of the filter plate 24 respectively, improving the cleaning effect and avoiding incomplete cleaning on one side. The two cleaning strips 23 are respectively set on both sides of the filter plate 24. The left inner wall of the rotating shaft 22 is fixedly connected to the output shaft of the motor 26.

[0022] Working principle: In terms of overall protection and observation, cabinet 1 serves as the main frame, supporting all internal electrical equipment and components. Cabinet door 3 opens and closes via a rotating connection to the front of cabinet 1—when closed, it seals the interior of cabinet 1, providing dustproof, moisture-proof, and safety protection; when open, it facilitates the inspection and operation of the internal equipment. The transparent glass observation window 4 on the inner wall of cabinet door 3 allows operators to directly observe the operating status of the electrical equipment inside cabinet 1 without opening cabinet door 3, improving operational convenience.

[0023] In terms of electrical equipment installation and adjustment, the mounting strips 5 are symmetrically fixed to the inner wall of the cabinet 1, and their evenly distributed slots provide adjustable installation positioning points for the mounting plate 6. The mounting plate 6, as the equipment support platform, can slide along the fixed posts 11 on the inner wall of the cabinet 1 to achieve height adjustment. During adjustment, the operator can push the movable plate 9 forward, causing it to slide along the limiting post 7 on the rear side of the mounting plate 6. At this time, the spring 8 connecting the mounting plate 6 and the movable plate 9 is compressed, and the locking block 10 on the front side of the movable plate 9 disengages from the slot of the mounting strip 5. After the mounting plate 6 is adjusted to the target height, the movable plate 9 is released, the spring 8 elastically resets, and pushes the movable plate 9 backward, causing the locking block 10 to re-engage into the corresponding height slot. The two symmetrically arranged locking blocks 10 respectively cooperate with the slots of the mounting strips 5 on both sides, ensuring that the mounting plate 6 is evenly stressed and firmly fixed, thereby achieving flexible adjustment of the electrical equipment installation height.

[0024] The ventilation component 2 on the inner right wall of cabinet 1 enables ventilation and heat dissipation inside cabinet 1: after being initially filtered by the isolation barrier 21, outside air enters cabinet 1 through the filter plate 24, achieving internal air circulation and heat dissipation. At the same time, when the motor 26 on the fixed plate 25 is working, its output shaft drives the rotating shaft 22 that passes through the filter plate 24 to rotate. The two cleaning strips 23 on the outer wall of the rotating shaft 22 rotate synchronously with the rotating shaft 22, and the two cleaning strips 23 are located on both sides of the filter plate 24, which can simultaneously clean the dust on both sides of the filter plate 24, avoid the filter plate 24 from being blocked, ensure ventilation efficiency, and ensure that the electrical equipment inside cabinet 1 operates stably in a suitable temperature environment.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
