Description

The technical solution relates to the design of a self-extinguishing automatic fire extinguishing device and also describes a method of stable fire protection of objects.

BACKGROUND OF THE INVENTION

Existing fire equipment such as. Portable fire extinguishers, mobile fire extinguishers, fixed fire extinguishers do not allow effective extinguishing of exposed areas, premises and equipment that are not controlled and fire-protected nonstop.

Important items require stable fire extinguishing systems to ensure constant and prompt readiness to release the extinguishing agent into the fire compartment. Stable systems are installation and operationally complex, requiring regular inspection. Various sensors are used to detect a fire, the reliability of which fundamentally affects the speed of the intervention, as well as the risk of a false trigger. For smaller buildings or various mass-produced items, such as engines of vehicles or electrical switchboards, classic fixed fire extinguishing systems are useless, take up a lot of space, are complicated and expensive.

It is desired and not known a solution that is light, simple and allows flexible installation in various conditions.

The essence of the technical solution

The aforementioned drawbacks of the prior art firefighting devices and apparatuses are largely overcome by the self-extinguishing automatic firefighting device according to the present invention, which consists in that the device consists of a closed hose, preferably a polyamide hose, in which the extinguishing agent is pressurized. The self-extinguishing automatic fire-fighting device consists of a hose, the ends of which are closed by means of firmly press-on terminals, inside the hose there is an extinguishing agent, the hose being adapted to disrupt its tightness by the fire. Preferably, the hose is at least partially flexible, which is achieved, for example, by using said polyamide hose. The extinguishing agent is under pressure in the hose, or the pressure is exerted or increased by fire.

For technological reasons it is advantageous if at least one hose end has a screw plug. At one end of the hose there is a fitting with a pressure valve for filling the extinguishing agent. The hose is closed by a screw at the end and protected by a shrink PVC protector. The other end of the hose is also crimped with a screw cap and protected with a shrink PVC protector. The use of a heat shrink PVC protector simplifies the final hose closure.

The extinguishing agent may be in the solid state and / or in the liquid state, and / or in the gaseous state. In order to achieve a sufficient volume of extinguishing agent, it is suitable that the hose has a length of at least 400 mm. A diameter of 18 mm has proved to be an optimal cross-section of the hose.

The fire hose has no corrosive effects on metals, destructive effects on plastics, nor does it damage electrical or electronic equipment. There is no danger to the space and equipment due to the extinguishing agent. If a liquid extinguishing agent is used, it will evaporate without residues in the event of a fire and there will be no extinguishing agent left in the area that could endanger persons or animals in the vicinity. The method of fire protection of objects by means of the device according to the invention, which consists in the fact that the hose with pressurized extinguishing agent is pre-fastened in the vicinity of the protected object and in case of fire, and / or hose integrity. As soon as a hole in the hose is created through the hole, the extinguishing agent escapes into the vicinity of the protected object, thus extinguishing the fire. Even before a fault occurs, a fire can increase the pressure of the extinguishing agent in the hose, which also contributes to its rapid release.

The hose will usually break at a temperature above 120 ° C. The hose may be attached directly to the object to be protected, preferably by means of flexible cable ties.

The technical solution provides a very simple and efficient construction of the device, where the hose jacket itself constitutes the carrier and the extinguishing agent envelope, the function of the envelope being the result of the inherent property of the hose material used. The device streamlines and increases the effectiveness of fire protection.

BRIEF DESCRIPTION OF THE DRAWINGS

The technical solution is explained in more detail with the help of Figures 1 to 3. The scale used and the ratio of the sizes of the individual elements to the length of the hose may not correspond to the description in the examples and these measures and sizes cannot be explained as a narrowing scope.

Figure 1 shows a view of a self-extinguishing automatic fire extinguisher. FIG. 2 shows a press-fit terminal with a pressure valve which is closed by a screw. FIG. 3 shows a press-fit crimped terminal.

Example

In this example of Figures 1 to 3, the self-extinguishing automatic fire-fighting device consists of a polyamide hose X having a length of at least 400 mm. The hose X may be long enough to contain the necessary protected space and / or equipment. The diameter of hose X in this example is 18 mm. In hose X, the extinguishing agent 2 is pressurized. At one end of the hose X there is a tightly crimped terminal 3 closed by a screw 4 and the entire end is provided with a heat shrink PVC protector. At the other end of the hose X there is a tightly crimped terminal 3 closed by a screw 4 and the entire end is fitted with a heat shrink PVC protector. These protectors ensure that minor injuries are avoided when handling the device and that any metal objects may not damage any sensitive objects when installing the device. At the same time, these protectors indicate the integrity of hose ends X. One hose end X is provided with a pressure valve 5 through which the extinguishing agent 2 is filled.

The self-extinguishing automatic fire-fighting equipment shall be mounted horizontally or vertically or in another direction on a fixed part of the space or equipment to be protected.

In case of fire, direct flame and temperature above 120 ° C, hose X bursts and extinguishing agent 2 enters the fire and extinguishes the flame. Fire hose X is supplied with 6 PVC cable ties to secure it securely to the protected area and / or equipment.

The softened polyamide wall of hose X ruptures precisely at the points of greatest thermal stress and releases extinguishing agent 2 into the space. The extinguishing agent 2 may be in a solid, liquid or gaseous state. The amount of extinguishing agent 2 can be controlled by the length and diameter of hose X. In the initial stages, the fire generates heat which increases the pressure in the hose X, which also contributes to sudden point disturbance of hose integrity X. .

Industrial usability

Industrial applicability is obvious. According to this technical solution, it is possible to produce and use self-extinguishing automatic fire-fighting equipment for the protection of objects and premises.
