The proposed self-propelled fire extinguishing device according to the concept of the proposed utility model includes a housing 1 inside which an explosive device is placed (not shown in FIG.), Connected to the outside through a hole 6 in the housing 1 by a fire-resistant cord (not shown in FIG.) And a fire extinguishing agent (on Fig. not indicated).

The body 1 of the fire extinguishing device is made of foam.

The hole 6 for the flame-retardant cord passes through a recess 5 closed around the housing 1, a width made on its outer side that exceeds the width of the flame-retardant cord, the outer part of which (the flame-retardant cord) is laid in it (recess 5).

On the inside of the housing 1, grooves 8 are made, facilitating its destruction when the explosive device is triggered.

The housing 1 can have various forms of execution including a ball, cube, ellipse, cylinder, prism, pyramid, cone or polyhedron, barrel-shaped, egg-shaped, cigar-shaped, needle-shaped, etc.

In the presented embodiment, the housing 1 is collapsible and consists of two parts 1 and 2, there is also a filling hole 4 for the extinguishing agent and a cover 7 of the filling hole 4.

Case 1 is safe to break and will not be harmful if it breaks when it enters a person.

The size of the housing 1 and its other parameters, as well as the volume of the explosive, the volume of the extinguishing agent are selected depending on the complexity of the fire and the area of the extinguishing zone.

When assembling a fire extinguishing device, an explosive (atomizer) is connected to a fire-retardant cord and then parts of the body 2 and 3 are connected using a thorn-groove connection.

The fire-resistant cord passes through the hole 6, fits into the recess 5 and is securely fixed in it.

The extinguishing agent is poured through the filling hole 4, then the lid 7 is inserted and glued.

Next, two layers of thermal film are applied to the housing 1 to prevent moisture from entering.

The proposed self-propelled fire extinguishing device operates as follows.

The principle of operation of the proposed self-actuating fire extinguishing device consists in ignition brought to the outer surface of the housing 1 and laid in the corresponding recess 5 of the fire-resistant cord from an open flame with the subsequent initiation of an explosive device located inside the housing 1, which leads to the destruction of the housing 1 and the uniform distribution of the extinguishing agent over the area or volume of combustion.

Two uses of the proposed fire extinguishing device are preferred.

As a result of the fact that the housing 1 on the inside contains grooves 8, which facilitate its rupture when the explosive device is triggered, its relatively uniform destruction is additionally provided, allowing the extinguishing agent to be sprayed freely in all directions in the required place, correspondingly increasing the degree of application efficiency and, accordingly, reliability use, in addition, the execution of the housing 1 of the foam promotes easy and safe for the environment gap, not requiring large to the amount of explosive, which comprehensively enhances efficiency and increases the reliability of the device during its operation.

The hole 6 for the flame-retardant cord passing through a recess 5 closed around the body, a width made on its outer side, which exceeds the width of the flame-retardant cord, allows its outer part to be laid into it (recess 5), creating a structure along the entire length of the surface (around the perimeter), which a fire-retardant cord is equipped, which increases the likelihood of tripping and reduces the expected response time of the device, thereby increasing the reliability and efficiency of extinguishing fires and localizing fire sources.

Thus, the solved technical problem (task) and, accordingly, the given technical result, are achieved thanks to the formulated set of essential features, which is graphically presented below:

- a self-actuating fire extinguishing device contains a foam plastic case 1 inside, which contains an explosive device connected to the outward through the hole 6 in the housing 1 with a fire-resistant cord and a fire extinguishing agent;
