[0029] The present application is further described in detail below through drawings and examples.

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 An embodiment of the present application provides an electric power box, comprising a cabinet 1, an induced draft fan 2 for pulling the wind direction, a dust removal assembly 3 and a filter screen 5, wherein a plurality of dust removal assemblies 3 are provided, and the plurality of dust removal assemblies 3 are respectively located on both sides of the induced draft fan 2, the dust removal assembly 3 comprises a dust removal net 32 ​​for dust filtering the air discharged from the cabinet 1, the dust removal assembly 3 is located on both sides of the inner wall of the cabinet 1, the induced draft fan 2 is located at the bottom of the inner wall of the cabinet 1, and the dust removal assembly 3 is installed in close contact with the induced draft fan 2.

[0031] Reference Figure 1 , Figure 2 and Figure 3 In one aspect of the present embodiment, the dust removal net 32 ​​is located on both sides of the cabinet 1, and a plurality of positioning holes are provided on the surface of the dust removal net 32, and fixing bolts 33 are connected to the internal threads of the positioning holes.

[0032] The dust removal assembly 3 also includes a bellows 30, which is located on one side of the inner wall of the cabinet 1. A plurality of exhaust fans 31 for exhausting air are fixedly installed inside the bellows 30, and the wind directions of the plurality of exhaust fans 31 are all to exhaust air outwards.

[0033] The filter screen 5 is located on the top of the cabinet 1 , and the filter screen 5 is connected to the cabinet 1 by magnetic adsorption.

[0034] When the wiring device is installed and used, air will enter through the filter 5 at the top of the cabinet 1. The filter 5 can not only achieve ventilation but also isolate some dust from entering the cabinet 1. At the same time, after the device has been running for a period of time, the induced draft fan 2 will start to absorb hot air while causing the dust scattered in the cabinet 1 to fall down until it reaches the bottom of the cabinet 1. At this time, the bellows 30 will start to run, and under the action of the exhaust fan 31, this part of the air will be discharged outward until it contacts the dust removal net 32 ​​and is discharged after the dust removal operation.

[0035] Reference Figure 3 and Figure 4 In one aspect of the present embodiment, a placement component 4 is fixedly installed inside the cabinet 1, and the placement component 4 includes a slide groove 40. A screw 41 is arranged inside the slide groove 40. A slider is slidably connected to the surface of the screw 41. A fixing plate 42 for placing a wiring device is fixedly connected to one side of the slider, and a large number of mounting holes are opened on the surface of the fixing plate 42.

[0036] The placement component 4 also includes a moving groove 43, which is located on the top of the fixed plate 42. A moving block is slidably connected inside the moving groove 43, and a mica board 44 for insulating effect is fixedly installed on one side of the moving block.

[0037] When the device is in use, the position of the fixed plate 42 is adjusted in the slide groove 40 according to the size of the wiring device until the wiring device can be placed in the cabinet 1. After the adjustment is completed, the device is installed on the fixed plate 42, and the position of the mica board 44 is adjusted in the movable groove 43 according to the installation position of the device, so that the mica board 44 can fit the device and play an effective insulation role.

[0038] All electrical equipment in this solution are powered by an external power supply.

[0039] Working principle: When in use, according to the size of the wiring device, adjust the position of the fixed plate 42 in the slide groove 40 until the wiring device can be placed in the cabinet 1. After the adjustment is completed, install the device on the fixed plate 42, and adjust the position of the mica board 44 in the movable groove 43 according to the installation position of the device, so that the mica board 44 can fit the device and play an effective insulation role. When the wiring device is installed and used, the top of the cabinet 1 will take in air through the filter 5. The filter 5 can not only play a ventilation effect but also isolate some dust from entering the interior of the cabinet 1. At the same time, after the equipment has been running for a period of time, the induced draft fan 2 is running, and while adsorbing hot air, it can make the dust scattered in the cabinet 1 fall down until it reaches the bottom of the cabinet 1. At this time, the bellows 30 is running, and under the action of the exhaust fan 31, this part of the air will be discharged outward until it contacts the dust removal net 32 ​​and is discharged after the dust removal operation.
