[0028] The above scheme is adopted: by setting the filter cover 302, the debris entering the interior of the electrical cabinet is blocked, and the air sucked by the fan 309 is kept relatively clean; by setting the support plate 304 and the support frame 305, the drive motor 306 can be fixed and supported in the working state; by setting the drive motor 306 as the power source of the ventilation mechanism 3, by rotating the drive shaft 308, the fan 309 is rotated to generate wind force to provide ventilation inside the electrical cabinet; by setting the drive shaft 308, the driving force is transmitted to rotate the fan 309; by setting the fan 309, through the transmission action of the drive shaft 308, strong wind is generated to achieve the effect of ventilation and keep the air circulation inside the electrical cabinet. Example

[0029] refer to Figure 1 and Figure 2A dustproof mechanism 4 is provided on the top of the electrical cabinet body 1, and the dustproof mechanism 4 includes a support column 401 and a dustproof plate 402. The support column 401 is fixedly installed on the top of the electrical cabinet body 1, and the dustproof plate 402 is fixedly installed on the top of the support column 401. A glass window 5 is installed on the top of the front of the electrical cabinet body 1, and a controller 6 is installed on the bottom of the front of the electrical cabinet body 1. An inspection plate 7 is fixedly connected to the back of the electrical cabinet body 1, and a sealing cotton is provided on the contact surface between the inspection plate 7 and the electrical cabinet body 1. The outer sides of the inspection plate 7 are threadedly connected with cover bolts 8, and the cover bolts 8 are threadedly connected to the electrical cabinet body 1.

[0030] The above scheme is adopted: through the setting of the support column 401, the dustproof plate 402 can be fixed and supported. Through the setting of the dustproof plate 402, the opening on the top of the electrical cabinet is blocked to prevent dust, rainwater and other debris from entering the interior of the electrical cabinet, thereby protecting the safe operation of the electrical equipment. Through the setting of the glass window 5, a visual operation interface is provided to facilitate observation of the operating status of the electrical equipment. Through the setting of the controller 6, the operating mode and parameters of the electrical equipment are controlled to ensure the normal operation of the equipment. Through the setting of the inspection panel 7 and the cover bolts 8, it is convenient for personnel to enter the interior of the electrical cabinet to inspect and maintain the equipment.

[0031] Working principle:

[0032] When in use, the electrical cabinet is installed at a corresponding position outdoors, and the supporting legs at the bottom help to stably place the electrical cabinet body 1 on the site. The controller 6 controls the electric hydraulic rod 204 to drive the waterproof plate 203 to rise and fall, and a good sealing effect is formed between the waterproof plate 203 and the circular groove 301 of the electrical cabinet body 1 through the sealing ring 205 to prevent rainwater and other liquids from entering the interior of the electrical cabinet. When ventilation and heat dissipation are required, the electric hydraulic rod 204 is used again to drive the waterproof plate 203 to expand outward, and the drive motor 306 is started at the same time. The drive motor 306 generates a driving torque to drive the drive shaft 308 to rotate, and the drive shaft 308 drives the fan 309 to work. The operation forms air flow, so that the hot air inside the electrical cabinet is discharged through the circular groove 301, so as to achieve the purpose of ventilation and heat dissipation. At the same time, the filter cover 302 can prevent some dust and debris from entering the interior. The dustproof plate 402 is used to prevent dust, leaves and other debris from falling into the top of the electrical cabinet, so as to protect the internal components from pollution. The operating status of the internal equipment can be visually viewed through the glass window 5 located on the top of the front of the electrical cabinet. If inspection or maintenance is required, the inspection panel 7 on the back can be removed through the cover bolts 8. Since the inspection panel 7 is equipped with sealing cotton, reinstalling the inspection panel after the maintenance work is completed can ensure the sealing of the electrical cabinet.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
