Abstract
The utility model provides a fire prevention electric cabinet, includes electric cabinet body (1), the door and each arris of electric cabinet (1) are airtight, and it has a protruding portion (11), and a ventilative stopper (3) is connected to the bottom surface of this protruding portion (11), and there is a ventilated membrane (31) that drains in the bottom surface of this ventilative stopper (3), the internal surface on the top of protruding portion (11) is located and is fixed with a temperature sensing box (2) directly over ventilative stopper (3), is equipped with sodium acetate trihydrate (21) in this temperature sensing box (2), and the bottom surface of this temperature sensing box (2) is screen cloth (22). When fire breaks out in the electric cabinet, the temperature rises, the sodium acetate trihydrate with the melting point of only one degree is quickly converted into a liquid state, and the sodium acetate trihydrate is dripped into the ventilating plug, so that the ventilating film in the ventilating plug is invalid, the inside and outside air of the electric cabinet is isolated, the fire is restrained, and finally flame is extinguished.
Description
Technical Field
The invention relates to a fireproof electric cabinet, in particular to an electric cabinet which can extinguish fire by isolating the air inside and outside the electric cabinet.
Background
At present, electronic components are widely used in enterprise production. However, the problem of electronic component ignition is always passive for enterprises, and firstly, the problem is difficult to find, and secondly, the fire spread is fast, and the loss is large. Particularly, for an electric cabinet with concentrated electronic components or a room with concentrated electronic components, the electronic components are worn and ignited after being used for a long time, and related parts are ignited due to the problems of short circuit and the like. Further, since flame retardant materials are often used for electronic components to reduce loss, it is very difficult to detect fire because of the small amount of smoke in the materials themselves when a smoke alarm is used to detect fire in a small area.
Disclosure of Invention
The invention aims to provide an electric cabinet which can quickly isolate the air inside and outside the electric cabinet and give an alarm after a fire breaks out in the electric cabinet.
In order to achieve the purpose, the electric cabinet comprises an electric cabinet body, a door and each edge of the electric cabinet are air-tight and provided with a protruding portion, the bottom surface of the protruding portion is connected with a vent plug, the bottom surface of the vent plug is provided with a waterproof vent film, a temperature-sensitive box is fixed on the inner surface of the top end of the protruding portion, which is positioned right above the vent plug, sodium acetate trihydrate is filled in the temperature-sensitive box, the bottom surface of the temperature-sensitive box is a screen, two sides of the vent plug, which are close to the bottom surface, are respectively provided with a lead, and the leads are connected with an alarm. When the liquid sodium acetate trihydrate contacts the lead, the lead is electrified, the alarm works, and workers are quickly informed.
When fire breaks out in the electric cabinet, the temperature rises, the sodium acetate trihydrate with the melting point of only 58 ℃ is quickly converted into liquid state, and the liquid sodium acetate trihydrate is dripped into the ventilating plug, so that the ventilating film in the ventilating plug is invalid, and therefore the inside and outside air of the electric cabinet is isolated to inhibit the fire behavior, and finally the flame is extinguished.
The electrical cabinet may be provided with a plurality of projections with temperature sensitive cells and venting plugs. The device can be arranged at any position where fire is likely to happen, so that the sensitivity is improved.
Drawings
FIG. 1 is a schematic of the present invention.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings.
As shown in the figure, the fireproof electric cabinet comprises an electric cabinet body 1, wherein the door and each edge of the electric cabinet 1 are hermetically sealed and are provided with a protruding portion 11, the bottom surface of the protruding portion 11 is connected with a vent plug 3, the bottom surface of the vent plug 3 is provided with a waterproof breathable film 31, a temperature sensing box 2 is fixed on the inner surface of the top end of the protruding portion 11 and is positioned right above the vent plug 3, sodium acetate trihydrate 21 is filled in the temperature sensing box 2, the bottom surface of the temperature sensing box 2 is a screen 22, two sides of the vent plug 3 close to the bottom surface are respectively provided with a lead 4, and the leads are connected with an alarm 41.
The electrical cabinet may be provided with a plurality of projections 11 with temperature sensitive cells 2 and venting plugs 3. Once a fire breaks out in the electric cabinet, the temperature rises, and the flame can be quickly extinguished, and the staff is informed to check the fire.
When fire breaks out in the electric cabinet, the temperature rises, the sodium acetate trihydrate with the melting point of only 58 ℃ is quickly converted into liquid state, and the liquid sodium acetate trihydrate is dripped into the ventilating plug, so that the ventilating film in the ventilating plug is invalid, and therefore the inside and outside air of the electric cabinet is isolated to inhibit the fire behavior, and finally the flame is extinguished.
