Description

Closed box body with active fire extinguishing function

Technical Field

The utility model relates to a closed box body, in particular to a closed box body with good active fire extinguishing performance.

Background

Some cable testing bridges, junction boxes, switch boxes, patch boards and the like are used for laying and fixing wires and cables and are closed box bodies of air-opening sockets, and the fireproof performance inside the box bodies is high in requirement, so that the cables are prevented from being burnt out when encountering fire. However, this type of box body only possesses the fire prevention function at present, and does not possess the function of putting out a fire, if the condition of a fire lasts long-time burning and does not put out a fire, can lead to the box body inside high temperature and cause the cable to damage, the conflagration spreads even.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problems, the utility model provides a closed box body with an active fire extinguishing function, which can actively extinguish fire when a fire occurs in the box body, so that a cable is prevented from being burnt out and a fire disaster is prevented from spreading.

In order to achieve the purpose, the utility model adopts the technical scheme that: the utility model provides a closed box body of function initiatively puts out a fire, includes the box body, the coating has put out a fire dope layer on the top inner wall of box body, put out a fire dope layer including meeting the cracked nanocapsule of high temperature, the parcel has the fire extinguishing agent in the nanocapsule.

As a further improvement of the utility model, the top end of the box body is a cover body which can be opened and closed, and the fire extinguishing coating layer is coated on the inner wall of the cover body.

As a further improvement of the utility model, the four side inner walls of the box body are also coated with fire-extinguishing coating layers.

As a further improvement of the utility model, the inner wall of the bottom of the box body is also coated with a fire-extinguishing coating layer.

As a further improvement of the utility model, the rupture temperature of the nano-capsules is 100-120 ℃.

The utility model has the beneficial effects that: according to the utility model, the top inner wall of the box body is coated with the fire extinguishing coating layer, when a fire occurs in the box body, the fire extinguishing coating layer above the fire point automatically breaks and releases the fire extinguishing agent when meeting high temperature, and the fire extinguishing coating layer can cover the fire point by scattering from top to bottom, so that fire is actively, effectively and accurately extinguished to protect the cable from being burnt out.

Drawings

FIG. 1 is a schematic view of the overall structure of the present invention;

FIG. 2 is a schematic view of the structure of a fire extinguishing coating layer;

description of the labeling: 1-box body, 2-cover body, 3-fire extinguishing coating layer, 4-nanocapsule and 5-fire extinguishing agent.

Detailed Description

The utility model is further described with reference to the following specific embodiments and the accompanying drawings.

As shown in figure 1, a closed box body with an active fire extinguishing function comprises a box body 1, wherein the top end of the box body 1 is provided with a cover body 2 which can be opened and closed, a fire extinguishing coating layer 3 is coated on the inner wall of the cover body 2, the fire extinguishing coating layer 3 comprises a plurality of nanocapsules 4 which are broken when meeting high temperature, and fire extinguishing agents 5 are wrapped in the nanocapsules 4. When the condition of a fire takes place inside box body 1, fire point top fire extinguishing coating layer 3 meets high temperature automatic break and releases fire extinguishing agent 5, and this fire extinguishing agent 5 has very high fire extinguishing performance to the mode release of gas or smog, from the top scatter and can cover the ignition point, can make 1 inside rapid cooling of box body, break the chain reaction free radical of burning, play the effect of putting out a fire, thereby initiatively, effectively, accurately put out a fire, do not burnt out with the protection cable. The nanocapsules 4 contained in the fire extinguishing coating layer 3 can be stored for a long time without going bad, but automatically break to release the fire extinguishing agent 5 when the open fire temperature reaches 100-120 ℃. Because each nanocapsule 4 contains the fire extinguishing agent 5, each time the fire extinguishing agent is triggered to release the fire extinguishing agent 5, the fire extinguishing agent is only locally released, and is partially broken first, and the rest of the fire extinguishing agent is broken subsequently, so that the effect of repeatedly and continuously breaking and releasing the fire extinguishing agent 5 is achieved, and the effect of repeatedly and continuously extinguishing fire is achieved.

Furthermore, the fire-extinguishing coating layers 3 are also coated on the inner walls of the four sides and the inner wall of the bottom of the box body 1, so that the fire-extinguishing action range and effect are improved.

The above-mentioned embodiments are only for convenience of illustration and not intended to limit the utility model in any way, and those skilled in the art will be able to make equivalents of the features of the utility model without departing from the technical scope of the utility model.
