Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0027] like Figure 1-5 As shown, the protective box of the electric intelligent segmentation device of this utility model is characterized by comprising a box body 1, a mounting frame 2 connected to the side of the box body 1, a partition 3 provided inside the box body 1, a plurality of mounting holes 4 opened on the partition 3, a bottom plate 5 installed at the bottom of the box body 1, a first inspection frame 6 connected to the side of the box body 1, a second inspection frame 7 provided on the bottom plate 5, and an explosion-proof cover 8 provided on the top of the box body 1; a first observation glass 9 is provided on both the first inspection frame 6 and the second inspection frame 7, and a second observation glass 10 is provided on the explosion-proof cover 8.
[0028] In this utility model's technical solution, a housing 1 provides space for internal components, a mounting frame 2 allows for the installation of switch components, and a partition 3 is installed inside the housing 1. Multiple mounting holes 4 on the partition 3 are used to fix various components of the device, achieving spatial separation and orderly layout, avoiding interference between components. A first inspection frame 6 and a second inspection frame 7 are respectively installed on the side and bottom plate of the housing 1, and are detachably connected to the housing 1 by first bolts 19 and second bolts 20, providing multi-directional inspection access for easy maintenance of components at different locations within the housing. A first observation glass 9 on the inspection frame allows observation of the internal component's operating status without disassembly, reducing unnecessary maintenance operations and improving efficiency. An explosion-proof cover 8 is detachably connected to the top of the housing by a third bolt 21, and a second observation glass 10 is installed on the top. The detachable top design facilitates maintenance of the upper components of the housing 1, and the second observation glass 10 allows for easy observation of the top components. This provides convenient inspection access and visual observation, reducing maintenance time, improving maintenance efficiency, and lowering the risk of component damage due to frequent disassembly.

[0034] The bottom of the box 1 is equipped with a fixing frame 23; the fixing frame 23 at the bottom of the box 1 can be used to securely install the protective box and enhance its stability in the outdoor environment.
[0035] Working Principle: The enclosure 1 provides space for internal components. The mounting frame 2 allows for the installation of switch components. A partition 3, installed inside the enclosure 1, has multiple mounting holes 4 for securing various components, achieving spatial separation and orderly layout, preventing interference between components. A first inspection frame 6 and a second inspection frame 7 are respectively located on the side and bottom plate of the enclosure 1, and are detachably connected to the enclosure 1 by first bolts 19 and second bolts 20, providing multi-directional access for maintenance. This facilitates maintenance of components in different locations within the enclosure. A first observation glass 9 on the inspection frame allows for observation of the internal components' operating status without disassembly, reducing unnecessary maintenance operations and improving efficiency. An explosion-proof cover 8 is detachably connected to the top of the enclosure by a third bolt 21. A second observation glass 10 is installed on the top; the detachable top design facilitates maintenance of components on the upper part of the enclosure 1, and the second observation glass 10 allows for easy observation of these components. This provides convenient access and visual observation, reducing maintenance time, improving efficiency, and lowering the risk of component damage due to frequent disassembly.
