Description
Technical Field
[0001] The utility model belongs to the technical field of electric control cabinets, and particularly relates to a mine electric control cabinet. Background Art
[0002] As an important electrical equipment, electric control cabinets are widely used in many fields such as industrial automation, power control, intelligent buildings, transportation, and coal mine and metal mine production. The mine electric control cabinets used in mine production such as coal mines and metal mines integrate the functions of monitoring, protecting, and controlling mine production equipment. They can real-time monitor the operating status, temperature, current, voltage and other parameters of mine production equipment, providing timely and accurate information for mine production management personnel.
[0003] Most mine electric control cabinets are installed indoors. In indoor installation, ventilation and heat dissipation are crucial factors. Impurities such as dust are likely to adhere to the electronic components inside the electric control cabinet, affecting the heat dissipation effect and even causing faults such as short circuits and electric leakage. In addition, if the heat generated by the electronic components during operation is not dissipated in time, it will cause the equipment temperature to be too high, affecting the performance and even damaging the equipment. Generally speaking, for dust prevention, a dust-proof net or filter is set at the air inlet of the electric control cabinet. In this method, the dust cleaning is frequent. For heat dissipation, heat dissipation holes are increased and the heat dissipation effect is improved by a heat dissipation fan. In this method, the increased ventilation through holes facilitate the entry of external dust into the interior of the electric control cabinet, increasing dust accumulation.

A connecting pipe 211 is provided on the side surface of the base 21, and the connecting pipe 211 communicates the base 21 and the dust-proof cover 41 to facilitate air flow. An air inlet hole 231 is provided on the side surface of the boss 23 to facilitate external gas to enter the inside of the boss 23 from the air inlet hole 231 and then enter the inside of the electric control cabinet body 1; an air flow circulation component is provided on the surface of the base 21, including a circulation fan 31 installed on the base 21, an air delivery pipe 32 communicating with the air inlet of the circulation fan 31, a collecting pipe 33 installed between the opposite surfaces of the air delivery pipe 32, and a manifold pipe 34 communicating the electric control cabinet body 1 and the collecting pipe 33. The circulation fan 31 is bolted to the base 21, and the circulation fan 31, the air delivery pipe 32, the collecting pipe 33, the manifold pipe 34, and the electric control cabinet body 1 are connected in sequence. The circulation fan 31 operates to suck air, and the hot air formed by the heat generated by the internal components of the electric control cabinet body 1 is sucked. The hot air passes through the manifold pipe 34, the collecting pipe 33, and the air delivery pipe 32 in sequence and is discharged into the inside of the base 21 by the circulation fan 31. Finally, it enters the dust-proof cover 41 along the connecting pipe 211 and is sprayed out from the first jet dust removal nozzle 42 and the second jet dust removal nozzle 43 to clean the dust on the surface layer of the flow guiding protrusion 5; a flow guiding protrusion 5 installed on the side surface at the bottom end of the boss 23, the flow guiding protrusion 5 is screwed to the boss 23, and a dust blocking pad 51 is provided on the surface of the flow guiding protrusion 5. The dust blocking pad 51 is adhesively bonded to the flow guiding protrusion 5. The flow guiding protrusion 5 plays a role in changing the air flow direction, so that the air flow flows along the direction of the air flow channel a; a dust-proof cover 41 installed on the side surface at the top end of the boss 23 and on the same side as the flow guiding protrusion 5. The inner surface of the dust-proof cover 41 is provided with a first jet dust removal nozzle 42 and symmetrically distributed second jet dust removal nozzles 43. The dust-proof cover 41 is screwed to the boss 23. After the hot air inside the base 21 enters the dust-proof cover 41, it is sprayed out from the first jet dust removal nozzle 42 and the second jet dust removal nozzle 43 to clean the dust on the surface layer of the flow guiding protrusion 5, so that the air flow containing dust is discharged from the gap between the end of the dust-proof cover 41 and the boss 23.

The dust blocking pad 51 and the blocking net 511 can block dust impurities, and the gas filtered by dust enters the cavity C of the boss 23. In addition, a dust-proof filter screen can be additionally added inside the boss 23 as needed to further prevent dust.
[0029] In this embodiment, the top end of the housing 22 is flush with the body 1 of the electric control cabinet, the bottom end of the housing 22 is flush with the top surface of the base 21.

The hot air passes through the manifold 34, the collecting pipe 33, and the air delivery pipe 32 in sequence, and is discharged into the cavity B inside the base 21 by the circulation fan 31. Finally, it enters the cavity C inside the dust-proof cover 41 along the connecting pipe 211, and is sprayed out from the first jet dust removal nozzle 42 and the second jet dust removal nozzle 43 to clean the dust on the surface of the diversion protrusion 5.

[0036] The hot air sequentially passes through the header pipe 34, the collecting pipe 33, and the air delivery pipe 32, and is discharged into the cavity B inside the base 21 by the circulation fan 31;
[0037] Finally, the hot air enters the cavity C inside the dust-proof cover 41 along the connecting pipe 211, and is ejected from the first jet dust-removing nozzle 42 and the second jet dust-removing nozzle 43 to clean the dust on the surface of the diversion protrusion 5, and timely clean the dust on the surface of the diversion protrusion 5, so as to avoid the situation where the dust accumulates and adheres firmly and finally cannot be blown away by the gas;
[0038] The second jet dust-removing nozzle 43 is in an inclined state tending to block the plate, and the gas ejected from the second jet dust-removing nozzle 43 flows towards the end of the dust-proof cover 41, so that the gas can be discharged to both sides;
[0039] The external air passes through the air inlet hole 231 along the air flow channel a and enters the inside of the boss 23. The dust-blocking pad 51 and the blocking net 511 can block dust impurities, and the gas filtered by the dust enters the cavity C of the boss 23.
