Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4As shown, this utility model provides a metal-armored withdrawable switchgear, comprising: an armored cabinet 1, with slide rails 2 symmetrically fixedly connected to the inner walls of both sides of the armored cabinet 1 near the bottom; sliders 23 are slidably embedded in the interior of the slide rails 2 near the rear side; a crossbeam 24 is fixedly connected between the outer surfaces of the two sliders 23; a spring-loaded switch 25 is installed at the bottom of the crossbeam 24; a mounting bracket 3 is fixedly connected to the top of the crossbeam 24; multiple mounting cavities 31 are equidistantly formed on the front surface of the mounting bracket 3; a light panel 32 is installed at the top of the mounting cavity 31; and a trapezoidal block 15 is installed at the bottom of the armored cabinet 1. Block 15 and spring-loaded switch 25 cooperate with each other. Spring-loaded switch 25 and light panel 32 are electrically connected by a circuit. The front surface of armored cabinet 1 is connected to cabinet door 16 by hinge. The left surface of armored cabinet 1 is provided with heat dissipation groove 11. The right surface of armored cabinet 1 is equipped with heat dissipation fan 12. The left surface of armored cabinet 1 is fixedly connected to a second protective shell 14 outside the heat dissipation groove 11. The right side and bottom of the second protective shell 14 are open. The right surface of armored cabinet 1 is fixedly connected to a first protective shell 13 outside the heat dissipation fan 12. The left side and bottom of the first protective shell 13 are open.

[0024] The overall effect of Embodiment 1 is that the lamp panel 32, the spring-loaded switch 25, the transformer, and the internal power supply lines of the armored switchgear are connected in series. When the spring-loaded switch 25 is pressed, the lamp panel 32 will be energized and convert electrical energy into light energy. The mounting cavity 31 is mainly used to install electrical equipment, and the armored cabinet 1 is mainly used to provide protection for the internal electrical components. When the metal armored switchgear is inspected and maintained at night, the mounting frame 3 can be pulled forward after opening the cabinet door 16. At this time, the mounting frame 3, the crossbeam 24, and the slider 23 will move forward. Since the slider 23 is located at the rear side of the slide rail 2 and also at the bottom of the mounting frame 3 near the rear side, after the slider 23 moves to the frontmost position inside the slide rail 2, the outer part of the mounting frame 3 will move out of the armored cabinet 1, which facilitates the inspection and maintenance of the electrical components inside the mounting cavity 31. During the process, as the crossbeam 24 moves forward... The spring-loaded switch 25 is first triggered by the pressure of the rear inclined surface of the trapezoidal block 15. When the crossbeam 24 moves to the front, the spring-loaded switch 25 is continuously pressed by the top plane of the trapezoidal block 15, thereby putting the lamp board 32 inside the mounting cavity 31 into a power supply and lighting state. The overall structure is simple and reasonable, solving the problem of small internal space and poor lighting when the metal armored switch equipment is inspected at night, improving maintenance efficiency and effectively ensuring power safety. The heat dissipation grooves 11 and cooling fans 12 on both sides of the armored cabinet 1 accelerate the internal and external air circulation during the use of the armored cabinet 1, thereby achieving the heat dissipation effect and avoiding the internal temperature from being too high and causing electrical component failure. In addition, the specially shaped first protective shell 13 and second protective shell 14 can effectively prevent rainwater from entering the armored cabinet 1 through the heat dissipation grooves 11 and cooling fans 12 on rainy days and causing circuit failure. The structure is simple and highly practical.

[0025] Example 2: Figures 1-4 As shown, a handle groove 33 is provided on the inner bottom of the mounting bracket 3 near the front surface. A first magnetic block 21 is fixedly installed at the front end of the slide rail 2, and a second magnetic block 22 is fixedly installed at the rear end of the slide rail 2. The rear surface of the first magnetic block 21 and the front surface of the slider 23 are magnetically attracted to each other, and the front surface of the second magnetic block 22 and the rear surface of the slider 23 are magnetically attracted to each other.

[0026] The effect achieved by the entire embodiment 2 is that, during the maintenance process, the handle groove 33 set at the bottom of the mounting bracket 3 facilitates the pulling of the mounting bracket 3 outward. When the mounting bracket 3 moves to the front side, the slider 23 will be magnetically attracted to the first magnetic block 21 on the front side. When the mounting bracket 3 moves to the rear side, the slider 23 will be magnetically attracted to the second magnetic block 22 on the rear side. This design structure is simple and effectively improves the stability of the mounting bracket 3 when it is pulled out for maintenance and reset, further improving its practicality.

[0027] Working Principle: When performing maintenance on metal-clad switchgear at night, opening cabinet door 16 allows pulling the mounting bracket 3 forward. This causes the mounting bracket 3, crossbeam 24, and slider 23 to move forward. Since slider 23 is located at the rear of slide rail 2 and also at the bottom of mounting bracket 3 near the rear, after slider 23 moves to the frontmost position inside slide rail 2, the outer part of mounting bracket 3 moves out of the armored cabinet 1, facilitating maintenance of the electrical components inside mounting cavity 31. During this process, as crossbeam 24 moves forward, the spring-loaded switch 25 is first pressed and triggered by the rear inclined surface of trapezoidal block 15. When crossbeam 24 reaches the frontmost position, the spring-loaded switch 25 is continuously pressed by the top plane of trapezoidal block 15, thus activating the lighting panel 32 inside mounting cavity 31. The overall structure is simple and reasonable, solving the problem of limited internal space and poor lighting during nighttime maintenance of metal-clad switchgear, improving efficiency. To improve maintenance efficiency and effectively ensure power safety, the heat dissipation slots 11 and cooling fans 12 on both sides of the armored cabinet 1 accelerate the internal and external air circulation during use, thereby achieving heat dissipation and preventing electrical component failure due to excessive internal temperature. Furthermore, the specially shaped first protective shell 13 and second protective shell 14 effectively prevent rainwater from entering the armored cabinet 1 through the heat dissipation slots 11 and cooling fans 12, thus preventing circuit failure. The structure is simple and highly practical. During maintenance, the handle slot 33 at the bottom of the mounting bracket 3 facilitates pulling the mounting bracket 3 outwards. When the mounting bracket 3 is moved to the front, the slider 23 magnetically attracts the first magnetic block 21 on the front; when the mounting bracket 3 is moved to the rear, the slider 23 magnetically attracts the second magnetic block 22 on the rear. This simple design effectively improves the stability of the mounting bracket 3 during maintenance and resetting, further enhancing its practicality.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
