in the working process of the self-starting closed fire extinguishing cabinet with internal and external air circulation uniform cooling, the cabinet is cooled by an indoor air conditioner in a non-fire state, air in a cabinet body 1 is extracted by an exhaust fan 4 and a cooling fire extinguishing pipeline 3, indoor air enters the cabinet body 1 through an air inlet switch filter 16 to achieve the purpose of replacing the air in the cabinet body 1, the air enters the cabinet body 1 through a conical filter screen 163, when more dust or sundries are filled outside the conical filter screen 163, a centrifugal motor 161 in the air inlet switch filter 16 drives the conical filter screen 163 to rotate, and sundries on the conical filter screen 163 are thrown out through centrifugal force to achieve the purpose of self-cleaning; when a fire occurs in the cabinet body 1, the sealing plate 1622 is opposite to the half of the conical filter screen 163 provided with the filter holes, the other end is opposite to the end provided with the conical filter screen 163 and provided with the switch closing plate 1631, the air inlet switch filter 16 is in a closed state, and by reducing the air inlet and keeping the exhaust fan 4 extracting the air in the cabinet body 1, the cabinet body 1 forms a negative pressure, the fire is extinguished by reducing the oxygen amount, the ambient temperature is detected by the temperature sensor, when the temperature is higher than the set value, the storage battery is communicated with the heating wire 1443 to enable the heating wire 1443 to generate heat, the gas in the glass hollow tube 1441 is heated to expand and finally crushed, the balancing weight 175 in the sealing starting mechanism 17 falls down, under the action of gravity, the counterweight 175 pulls the limiting rod 172 to contract, so that the laminated sealing sleeve 15 falls and expands to seal the cabinet body 11; in the electric starting gas cylinder 14, the opening of the bottle body 141 loses the sealing of the electric breaking glass tube 144, the internal carbon dioxide gas is filled in the cabinet body 11, thereby reducing the contact amount of oxygen and a fire point, and finally achieving the purpose of fire extinguishing, air is arranged in the glass hollow tube 1441, the breaking starting can be heating by a heating wire 1443 or flame starting through fire, when the cabinet body 1 catches fire, the electric breaking glass tube 144 is broken, the movable hinge lug 176 is separated from the fixed hinge lug, the balancing weight 175 falls under the action of gravity, the limiting rod 172 is pulled by the balancing weight 175 to contract towards the interior of the cabinet body 1, so that the limiting rod 172 is separated from the sleeve 151, the sleeve 151 falls under the action of gravity, and the purpose of sealing the cabinet body 1 is achieved through the matching of the sleeve 151 and the supporting platform 152.
According to the self-starting closed fire extinguishing cabinet with the internal and external air circulation and uniform cooling, air in the cabinet can be continuously updated by pumping the air in the cabinet through the cooling fire extinguishing pipeline 3 and the exhaust fan 4, the temperature in the cabinet and the temperature outside the cabinet can be quickly interacted, the air entering the cabinet can be filtered through the air inlet switch filter 16, the filtering mechanism can be self-cleaned, meanwhile, when a fire disaster happens, the filter can be closed, the air entering is reduced, when the fire disaster happens, the interior and the exterior of the cabinet are isolated through a plurality of measures such as the laminated sealing sleeve 15 and the electrically started gas cylinder 14, the fire is extinguished in an oxygen-deficient mode, the damage to electronic components of equipment is small, and the repair is convenient.
The above embodiments are illustrative of the present invention, and are not intended to limit the present invention, and any simple modifications of the present invention are within the scope of the present invention.
