Referring to fig. 4, in the embodiment of the present invention, when the cover plate 5 is rotated to the vertical state, the bayonet 52 just can pierce the elastic sealing film 102 on the gas storage tank 101.
When the cover plate 5 is opened, the bayonet 52 on the balancing weight 51 moves to the position of the gas storage tank 101, and the elastic sealing film 102 on the gas storage tank 101 pierces, so that the carbon dioxide compressed gas in the gas storage tank 101 can be sprayed out to further extinguish the fire.
Embodiment three differs from embodiment one in that:
referring to fig. 4, in the embodiment of the present invention, a baffle plate 53 is vertically disposed on one side of the cover plate 5 near the limiting cylinder 91, the baffle plate 53 is made of iron, a magnet block 103 is embedded in the top side of the interior of the cabinet body 1, the lower portion of the magnet block 103 is flush with the top side of the interior of the cabinet body 1, the magnet block 103 is located at one side of the limiting cylinder 91, and when the baffle plate 53 is in a horizontal state, one side of the baffle plate 53 far from the cover plate 5 is exactly lapped on the magnet block 103 and seals the opening of the lower portion of the limiting cylinder 91.
When the fire extinguishing device is used, after the cover plate 5 is opened, the cover plate 5 can rotate downwards, meanwhile, the cover plate 5 can drive the baffle plate 53 to rotate upwards, when the cover plate 5 moves to a vertical state, the baffle plate 53 can rotate to a horizontal state, and as the baffle plate 53 is made of iron, the magnet block 103 can adsorb the baffle plate 53 and fix the baffle plate 53, at the moment, the baffle plate 53 can seal and block the opening at the lower end of the limiting cylinder 91, so that the effect of isolating air is achieved, and the fire disaster can be extinguished rapidly.
Working principle: when a fire disaster occurs in a circuit in the cabinet body 1, smoke is generated, the smoke enters the limiting cylinder 91, the smoke pushes the piston plate 99 to move along with the increase of the smoke, the piston plate 99 moves upwards, when the piston plate 99 moves to the upper part of the smoke outlet 98, the smoke is discharged from the smoke outlet 98, and when the piston plate 99 moves upwards, the moving shaft 92 moves downwards under the gravity of the moving shaft 92, the limiting rope 7 is cut off by the cutting knife 910 at the lower end of the moving shaft 92, after the limiting rope 7 is cut off under the gravity of the balancing weight 51, the cover plate 5 is opened, and the dry powder agent 8 above the cover plate 5 falls down to extinguish the fire disaster;
when the cover plate 5 is opened, the bayonet 52 on the balancing weight 51 moves to the position of the gas storage tank 101, and the elastic sealing film 102 on the gas storage tank 101 is pierced, at the moment, the compressed carbon dioxide gas in the gas storage tank 101 is sprayed out to further extinguish the fire;
after the apron 5 is opened, apron 5 can rotate downwards, and apron 5 can drive baffle 53 again and rotate upwards simultaneously, and when apron 5 moved to vertical state, baffle 53 can rotate the horizontality, and because baffle 53 is the iron material, consequently magnet piece 103 can adsorb baffle 53, holds baffle 53 for fixed, and baffle 53 will give the shutoff with the opening of spacing section of thick bamboo 91 lower extreme this moment, plays the effect of isolated air for the conflagration is quick to be put out.
And all that is not described in detail in this specification is well known to those skilled in the art.
