Technical field
Trie technical solution concerns the construction layout of the decentralised fire-fighting device with gradual extinguishing agent release option.
Background Art
Many different types of fire-extinguishing systems are known today, such as portable fire- extinguishers, centralised fire-extinguishing systems, mobile fire-extinguishing systems and many other fire protection systems.
Other known systems are automatic self-extinguishing fire devices, which are installed in vessels containing the described extinguishing agent and trigger mechanism, for instance, in UV " 21264. A further option is a system in which the extinguishing agent vessel is replaced by a hose with closable ends that contains the extinguishing agent, which is activated by heat in such a manner that the hose pipe is disrupted and thereby results in the one-off release of the extinguishing mixture. This principle is described in the Slovak utility models 7684 and 7760.
The disadvantage of the above-mentioned solution is the fact that the decentralised fire- extinguishing principle cannot be applied to older systems with a power supply. However, the disadvantage of the newest solutions that do not require a power supply is the fact that activation of the decentralised fire extinguishing devices releases all the extinguishing agent at once, which reduces the quality of fire-extinguishing. In the case of the described utility models 7684 and 7760, the disadvantage in addition to the fact that the extinguishing agent is fully released is also the fact that the material of the hose containing the extinguishing agent is not temperature stable and the extinguishing agent can be prematurely released without the presence of flames.
Disclosure of the invention
The above-stated disadvantages are to a greater extent eliminated by the decentralised fire- fighting device according to this technical solution, the principle of which lies in that the extinguishing agent is contained in a hollow multi-layer profile made of gas-tight, mechanically and thermally resistant material, which has end cap sealing at both ends, where at least one end cap has a filling valve, and the blinds are protected by a dielectric sleeve. The valve has a through hollow profile comprising a multi-layer non-homogeneous material filled with a fire-extinguishing substance. The hollow profile contains at least one additional layer against mechanical and/or thermal damage. The interior of the hollow profile contains at least one decelerating barrier, which divides the hollow profile into individual chambers, and also has the advantage that it contains a thermal conductor, which is attached to both end caps and ensures the distribution of the heat in the extinguishing agent, both passively and actively in case of connection of a power supply, and at least one end cap has an indicator of the presence and eventually also the quantity of the extinguishing agent. The outer layer of the multi-layer hollow profile need not be permanently bonded with the profile, respectively, the rrmlti-layer profile may be covered with a protective sleeve.
Upon action of heat above 80 ° C, the integrity of the hollow multi-layer profile or the protective sleeve is disrupted and the extinguishing agent is gradually released through the individual partitions (one or more partitions) for better and longer flooding of the given area with extinguishing agent. The heat conductor in the profile is used for uniform heating and activation of the extinguishing agent and may also serve as a safety device for the ends.
Brief Description of the drawings
The details of the technical solution shall be clarified by means of a drawing, where Figure 1 shows the cross-section of the decentralised fire extinguishing system.
Modes for carrying out the invention
The decentralised fire-fighting device consists of the hollow multi-layer profile 1 filled with extinguishing agent that is made of gas-tight, mechanically and thermally resistant material, which has end caps at both ends 2 and where at least one end cap has a filling valve 3, whereas the end caps are protected by a dielectric sleeve 4. The interior of the hollow multilayer profile I has at least one deceleration partition 5, which divides the hollow multi-layer profile I into individual chambers. Further, the interior of the hollow multi-layer profile i has a heat conductor 6, which is connected to the end caps. One of the end caps has an attached indicator 7 of the presence of extinguishing agent. The hollow multi-layer profile (1) is disrupted at temperatures above 80° C. The heat conductor 6 ensures uniform distribution of heat, both passively and actively if connected to a power source.
Industrial applicability
This technical solution is applicable in places where it is not possible or difficult to use power supplies or in places where it is necessary to apply a decentralised or fully automatic fire protection system.
