As shown in fig. 1 to 8, a dust-proof low-voltage switchgear 100 of the present application includes: the device comprises a cabinet body 10, a fan 11 arranged at the lower end of the cabinet body 10, a filter box 12 arranged at the upper end of the cabinet body 10, and a wind shield 13 arranged at the lower end of the cabinet body 10;

the fan 11 is a suction fan, the suction fan 11 is communicated with the bottom end of the cabinet body 10, a relatively sealed cavity is arranged in the cabinet body 10, and electronic devices are stored in the cabinet body 10; a filter screen 121 is arranged in the filter box 12, one end of the filter screen 12 is provided with an air inlet 122, and the other end of the filter screen 12 is communicated with the cabinet 10 through an air inlet pipe 123. So, after fan 11 opens, can be continuous take out the gas in the cabinet body 10 to blow off the external cabinet, and the air that gets into the internal cabinet 10 needs to get into the cabinet body 10 from this rose box 12, so, after filtering through filter screen 121, can play the dust removal effect.

In a general workshop, the dust at the lower end of the cabinet body 10 is more, and the dust entering the filter box 12 can be reduced by arranging the filter box 12 at the bottom end of the cabinet body 10, so that the service life of the filter screen 121 is prolonged. Further, in order to prevent the air blown out by the fan 11 from blowing on the bottom surface, which causes further dust emission, a wind shield 13 is disposed at the bottom end of the cabinet, and the air blown out by the fan 11 is guided by the wind shield 13.

Specifically, the lower extreme of the cabinet body 10 is provided with support 101, be connected with bottom plate 102 on the support 101, fan 11 sets up on the bottom plate 102, windshield 13 along the circumferential direction of support 101 arranges, wraps up the side of support 101, windshield 13 with the clearance has between the lower extreme of the cabinet body 10, its the tip of windshield 13 is loudspeaker form. In this way, the windshield 13 can direct the airflow from the fan 11 to direct the airflow upward.

The filter screen 121 is a key device for ensuring the dust removal effect, and thus the filter screen 121 needs to be replaced and cleaned regularly. For this purpose, the filter screen 121 and the filter box 12 are detachably connected.

Specifically, the filter box 12 is provided with guide blocks 211, a guide groove is formed between the two guide blocks 211, and the filter screen 121 is fixed by the filter plate holder 30.

Specifically, the filter plate frame 30 includes fixed frame 311, wears to establish guide shaft 312 on the fixed frame 311, the elastic component 313 of cover on receiving guide shaft 312, wherein fixed frame 311 sets up and is provided with two, and two fixed frames 311 can slide on guide shaft 312, and elastic component 313 is used for connecting two fixed frames 311 to elastic component 313 is used for exporting outside elasticity for two fixed frames 311, so under elastic component 313's effect, has the clearance between two fixed frames 311.

The side of the filter box 12 is provided with a slot 212, and the side wall of the slot 212 is provided with an arc block 2121, so that the filter plate holder 30 is inserted into the guide slot along the slot 212, the two fixing frames 311 can be clamped by the guide block 211 to fix the filter plates 11, and the gap between the fixing frames 311 and the filter screen 121 is sealed.

Further, when the filter box is used, it is necessary to prevent gaps from being formed between the fixing frame 311 and the filter net 121 and the fixing frame 311 as much as possible, and if the distance between the guide grooves is set too small, it is difficult to insert the fixing frame 311 into the guide grooves, so that the filter box 12 is further provided with a pressing device which can clamp the two fixing frames 311 after the fixing frame 311 is inserted into the guide grooves.

Specifically, the pressing device includes a top rod 221 penetrating through the guide block 211, a first inclined block 222 connected to the top rod 211, a second inclined block 223 arranged opposite to the first inclined block 222, a screw 224 rotatably connected to the second inclined block 223, and a first spring 225 sleeved on the top rod 221.

Wherein, one end of the first spring 225 is connected with the ring plate at the end of the top rod 221, and the other end is connected with the guide block 211. A groove 311a is provided in the fixing frame 311, the push rod 221 faces the groove 311a, and the push rod 221 is pulled to a position where it is in contact with the guide block 211 by the first spring 225.

Be provided with screw 2240 on rose box 12, screw 224 wears to establish on screw 2240, so through the mode of rotating screw 224, can push second sloping block 223 downwards, and then second sloping block 223 transversely pushes away first sloping block 222 to extrude the effect of fixed frame 311 through ejector pin 221 greatly.

Further, an ash collecting device is disposed on the filter box 12, and the ash collecting device is disposed at one side of the slot 212, and can collect dust on the filter screen 121 when the filter screen 121 is pulled out.

The ash collecting device comprises a first telescopic piece 41 connected with the filter box 12, a guide block 42 connected with the first telescopic piece 41, a second telescopic piece 43 connected with the guide block 42, a scraping plate 44 connected with the second telescopic piece 43, and a pressing plate 45 arranged on the guide block 42 in a sliding mode.

Wherein, the first and the second telescopic parts are springs. The guide block 42 is provided at one side of the arc block 2121 when it is desired to pull the filter plate out of the slot 211.

The guide block 42 of pulling, and then under the promotion of second extensible member 43, scraper blade 45 promotes to the position with arc piece 2121 tip butt, and the spacing first extensible member 41 of scraper blade 45 resets this moment, and the filter screen 121 that pulls out simultaneously will with scraper blade 45 butt, and then the dust will be scraped by scraper blade 45.

Further, a guide rail 120 is provided at the lower end of the filter box 12, and the guide rail 120 is disposed in an inclined manner, so that dust scraped by the scraper 45 will fall on the guide rail 120.
