Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet technology, and in particular to an explosion-proof electrical cabinet that is easy to maintain. Background Technology

[0002] During use, electrical cabinets often experience short circuits due to factors such as aging wire insulation, design defects, or human error. This generates a large current, which instantly produces high-temperature, high-pressure gas. However, because electrical cabinets are narrow, the generated high-pressure, high-temperature gas cannot be effectively released in a short time. Therefore, the cabinet can easily explode, endangering the safety of staff and damaging adjacent electrical cabinets. As a result, explosion-proof electrical cabinets have become widely used.

[0003] Currently, in actual use, explosion-proof electrical cabinets are mostly equipped with baffles at the edge where the safety door contacts the cabinet to prevent external water from entering the cabinet through the safety door seal. However, when cleaning the dust inside the cabinet, the dust swept off by the baffle will accumulate at the bottom of the cabinet and is difficult to clean, which brings inconvenience to subsequent maintenance. Utility Model Content

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Example 1, such as Figure 1-3 As shown, this utility model provides a technical solution for an explosion-proof electrical cabinet that is easy to maintain: it includes an electrical cabinet shell 1, and a drain port 11 is provided on the bottom surface of the electrical cabinet shell 1. The drain port 11 extends to the bottom of the electrical cabinet shell 1. A pull-out frame 12 is fixed to the bottom of the electrical cabinet shell 1. One side of the pull-out frame 12 is open, and the inner wall of the pull-out frame 12 is flush with the inner wall of the drain port 11. A sealing plate 10 slides between the inner walls of the pull-out frame 12 and is located directly below the drain port 11.

[0024] The effect achieved by the entire embodiment 1 is that, in actual use, by opening a drain port 11 on the inner bottom surface of the electrical cabinet shell 1 and extending the drain port 11 through to the bottom of the electrical cabinet shell 1, the dust swept off when cleaning the dust inside the electrical cabinet shell 1 falls to the inner bottom surface of the electrical cabinet shell 1 and can be discharged from the drain port 11.

[0025] Example 2, as Figure 1-3As shown, a lever 13 is fixed to the bottom of the sealing plate 10 near one side edge. The top of the sealing plate 10 is in contact with the bottom of the electrical cabinet shell 1. A baffle frame 3 is fixed to the inner wall of the electrical cabinet shell 1 near the front edge.
