Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Example 1
Referring to fig. 1-4, an isolated fire-proof power distribution cabinet comprises a cabinet body 1 for mounting an electric device, a liquid storage tank 2 for filling fire extinguishing agent is arranged at the upper end of the cabinet body 1, the fire extinguishing agent adopts high-pressure carbon dioxide gas, sliding grooves 3 are symmetrically arranged at the upper end of the side wall of the cabinet body 1, a sliding block 4 is elastically connected in each sliding groove 3 through a return spring 8, each slide block 4 is connected with the corresponding slide groove 3 in a sealing and sliding way, the groove wall of each slide groove 3 is symmetrically provided with a vent 5 which communicates the slide groove 3 with the outside and the inside of the cabinet body 1, each slide block 4 is provided with a plurality of through holes 6 which are matched with the vent 5, the upper end of the groove wall of each slide groove 3 is provided with an air inlet pipe 9 which communicates the slide groove 3 with the inside of the cabinet body 1, each air inlet pipe 9 is positioned above the plurality of ventilation openings 5, and fire extinguishing pipes 7 are communicated between the top groove wall of each sliding groove 3 and the liquid storage tank 2;
a plurality of first control grooves 10 communicated with the fire extinguishing pipe 7 are symmetrically formed in the inner top wall of the cabinet body 1, a heat conducting block 12 is fixedly connected to the groove opening of each first control groove 10 in a sealing mode, the upper end face of each heat conducting block 12 is elastically connected with a heat insulating block 11 through a first memory spring 13, the first memory spring 13 can be made of a thermal deformation metal material with the metamorphic temperature of about two hundred degrees centigrade, each heat insulating block 11 is connected with the corresponding first control groove 10 in a sealing and sliding mode, the sealing space of each first memory spring 13 is a driving area, heat conducting oil is filled in each driving area, heat inside the cabinet body 1 can be quickly conducted to the position of the first memory spring 13 through the heat conducting oil and the heat conducting block 12, a circulation groove 14 matched with the fire extinguishing pipe 7 is formed in each heat insulating block 11, and conduction of the heat in the circulation groove 14 to the first memory spring 13 can be reduced through the heat insulating blocks 11, thereby avoiding that the fire extinguishing agent cools down the first memory spring 13 quickly when flowing in the circulation groove 14, thereby influencing the flow of the fire extinguishing agent in the circulation groove 14.
The invention can be illustrated by the following operating modes: initially, notches at two ends of a circulation groove 14 on the heat insulation block 11 under the limiting action of a first memory spring 13 are staggered with the fire extinguishing pipe 7, the fire extinguishing pipe 7 is in a blocked state, the air inlet pipe 9 is blocked by the slide block 4, openings at two ends of a through hole 6 in the slide block 4 are opposite to ventilation openings 5 at two sides of the slide groove 3, and the ventilation openings 5 are in a conduction state, so that heat dissipation in the cabinet body 1 can be assisted;
when a fire breaks out in the cabinet body 1, the temperature in the cabinet body 1 rises rapidly, the temperature in the driving area rises rapidly to reach the metamorphosis temperature of the first memory spring 13, the first memory spring 13 extends and pushes the heat insulation block 11 to move upwards, the circulation groove 14 on the heat insulation block is communicated with the fire extinguishing pipe 7 relatively, high-pressure carbon dioxide gas in the liquid storage tank 2 sequentially passes through the fire extinguishing pipe 7 and the circulation groove 14 to enter the sliding groove 3 and pushes the sliding block 4 to move downwards until the fire extinguishing pipe 7 is communicated with the air inlet pipe 9 through the sliding groove 3 and is sprayed into the cabinet body 1 through the air inlet pipe 9, and therefore the fire behavior in the cabinet body 1 can be controlled;
it is worth noting that, this moment because the removal of slider 4, through-hole 6 on the slider 4 misplaces with a plurality of vents 5 that correspond, and a plurality of vents 5 all are in by the shutoff state to can keep apart the high-pressure carbon dioxide gas of avoiding through vent 5 escape to the external world with the cabinet body 1 is inside, make the carbon dioxide gas of the internal packing of the cabinet body can be in the cabinet body 1 in save time more for a specified time, be convenient for thoroughly extinguish the flame.
Example 2
Referring to fig. 5 to 6, the present embodiment is different from embodiment 1 in that: second control tank 15 has been seted up to 1 lateral wall lower extreme symmetry of the cabinet body, all there is piston plate 17 through second memory spring 16 elastic connection on the diapire in every second control tank 15, and every piston plate 17 lateral wall all with the sealed sliding connection of cell wall of the second control tank 15 that corresponds, second memory spring 16 can adopt the metamorphosis temperature to make at the thermal deformation metal material about two hundred degrees centigrade, it is equipped with communicating pipe 18 all to communicate between the drive area that every second control tank 15 top cell wall and position correspond, the confined space that piston plate 17 up end and second control tank 15 are constituteed is the control area, every control area all fills with the communicating pipe 18 that corresponds has the conduction oil.
When the lower part of the cabinet body 1 is on fire, because the upper end of the side wall of the cabinet body 1 is provided with the plurality of ventilation openings 5, the heat is difficult to be transferred to the first memory springs 13 in time, for the embodiment, because the plurality of second memory springs 16 are all positioned at the lower side of the cabinet body 1, when the lower side of the cabinet body 1 is on fire, the heat conducting oil in the second control groove 15 can rapidly transfer the heat in the cabinet body 1 to the second memory springs 16, when the temperature of the second memory springs 16 reaches the abnormal temperature, the second memory springs 16 extend and push the piston plates 17 to extrude the control area, the heat conducting oil in the control area enters the corresponding driving area through the communicating pipes 18, so as to push the corresponding heat insulation blocks 11 to move upwards and stretch the first memory springs 13, so that the circulation grooves 14 on the corresponding heat insulation blocks 11 are communicated with the fire extinguishing pipes 7 to extinguish the fire inside the cabinet body 1, and the device can effectively treat the fire at each position inside the cabinet body 1 in time, the use effect is good.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention and the equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
