when the ultrasonic switch cabinet is in use, because the upper filter plate 112 is made of metal material, the lower filter plate 113 is made of plastic material, and the resonance block 116 is positioned on the lower filter plate 113, after the ultrasonic generator 4 is started and the resonance block 116 vibrates, the resonance block 116 can drive the lower filter plate 113 to move relative to the upper filter plate 112, meanwhile, because the first through hole 114 on the upper filter plate 112 and the second through hole 115 on the lower filter plate 113 are staggered, when the lower filter plate 113 moves relative to the upper filter plate 112, the first through hole 114 and the second through hole 115 are overlapped, so that the passing area reaches the maximum, at the moment, dust on the filter screen passes through the filter screen and is discharged out of the switch cabinet, meanwhile, in the use process, a certain shearing effect exists between the first through hole 114 and the second through hole 115 through the relative movement between the upper filter plate 112 and the lower filter plate 113, can carry out certain shearing to the dust of card in the hole on the filter screen when passing the filter screen, promote the dust to pass through the filter screen, avoid the external dust that enters into in the cabinet body 1 of part to reunite each other, lead to passing the filter screen smoothly, make the dust gather in the cabinet body 1, influence the normal operating of the interior electric elements 15 of cubical switchboard.
The specific working process is as follows:
when the switch cabinet is in work, the electric element 15 installed in the switch cabinet comprises various sensors and is used for monitoring the running state of equipment in the switch cabinet and the environment in the switch cabinet, transmitting monitoring data to the remote control end through a network, adjusting or remotely controlling the running parameters of the equipment in the switch cabinet through the remote control end, and monitoring the running environment in the switch cabinet; meanwhile, in the operation process of the switch cabinet, the operation of the fan 3 is controlled by the controller, so that the air with lower external temperature enters the cabinet body 1 from the air inlet 12 at the bottom of the cabinet body 1, then the air entering the cabinet body 1 moves upwards in the cabinet body 1, is discharged to the outside of the cabinet body 1 from the air outlet 11 through the fan 3, and discharges the heat in the cabinet body 1, meanwhile, the air in the cabinet body 1 circulates with the outside, when the temperature in the cabinet body 1 is reduced, impurities such as dust and the like in the external environment enter the cabinet body 1, in addition, the impurities are accumulated in the cabinet body 1 under the influence of an electric field and a magnetic field generated when the electric element 15 in the cabinet body 1 operates, meanwhile, the ultrasonic generator 4 is controlled by the controller to be started to generate ultrasonic waves, the ultrasonic waves are continuously reflected in the cabinet body 1, so that the film 22 on the inner wall of the cabinet body 1 and the surface in the electric element 15 generate tiny vibration, the impurities such as dust and the like attached to the inner wall of the cabinet body 1 or the surface of the electric element 15 are shaken off, so that the impurities move along with the airflow caused by the fan 3 and are discharged to the outside of the cabinet body 1 through the filter screen;
