Definitions
- the invention concerns the construction realization of the automatic fire self- extinguishing device for extinguishing of fire and it also discloses method of stable fire protection of the objects.
- WO201 1092189 discloses a solution where after the burning through of the hose with the pressure medium a pyrotechnical element, which subsequently pushes the extinguishing medium through the opening in the hose to the seat of fire.
- This solution is complicated and space-consuming; it requires independent vessel for the extinguishing medium and it includes multiple elements of the system.
- the invention according to DE10163527 uses sensors and independent vessels of extinguishing medium, which leads to increased costs and demands on space of the system.
- Solution according to DE 10224505 uses a hose with two layers, whereby one layer is perforated and thermally stable and second layer is sensitive to heat and in a place of fire it melts and thereby allows the extinguishing medium to flow out of the hose at correct place.
- This solution requires complicated and specialized production of the hose which increases costs.
- the abovementioned deficiences of hitherto known fire extinguishing devices are significantly remedied by automatic self-extinguishing device according to this invention, which essence lies in the fact that the device comprises of closed hose, preferably polyamide hose, which is under pressure filled by extinguishing substance.
- the hose is dimensioned by its length and diameter in such a way that it forms the cache of the extinguishing substance and no independent pressure vessel with the extinguishing substance is necessary.
- the extinguishing substance or medium can be on the hexafluoropropane basis.
- An ending with pressure valve is pressed on one end of the hose; it is closed by the screw and protected by the shrinking PVC protector (also known as "heat-shrink tubing").
- An ending is pressed on the other hand of the hose, too; it is closed by the screw and protected by the shrinking PVC protector.
- the PVC protector functions as electrical insulator, so that during the placement of the hose to electric distribution or in the vicinity of electric devices (for example car battery in an engine) the metal endings of the hose cannot cause short- circuiting during random touch.
- the hose is produced from at least partially transparent material.
- the extinguishing devices are usually produced and distributed as colorless. In order to make extinguishing substance more visible it can be colored and during the check it sufficies to check the color of the hose.
- a control surface with the color corresponding to the color of the extinguishing substance inside the hose can be attached to the hose from the outside. This indirectly controls the pressure of the extinguishing substace; it even controls the slow decrease in the pressure cause by the leak of extinguishing substance; this leak can take a long time without being noticed.
- the hose according to this invention allows visual control of the extinguishing substance.
- a small floating body - for example of spherical shape and with strong, for example reflexive color - can be placed inside the transparent or at least partially transparent hose.
- the floater is in the highest fold of the hose.
- the floater descends, which can be easily visually checked.
- the use of at least partially transparent hose together with the coloring of the extinguishing substance or together with the floating body simplifies the functionality of the device. The transparency must be ensured at least to such a degree that the color or floating body can be seen by naked eye.
- the extinguishing hose has no corrosive effects on the metals; no destructive effects on the plastic; it does not harm eletric or electronic devices. There is no danger to the space and devices under the effects of the extinguishing substance. In case of use of the liquid extinguishing substance, this substance evaporates without remnants in case of fire, and there are no remnants of the extinguishing substance which could har persons or animals in the environment.
- the deficiencies in the prior state of the art are significantly remedied by the fire protection method of objects by a device according to this invention which essence lies in the fact that the hose with the pressurized extinguishing substance is attached in advance in the vicinity of the protected object and in case of fire the sealing and/or integrity of the hose is disrupted.
- the extinguishing substance leaks through this opening to the vicinity of the protected object, which extinguishes the fire. Even before the crash or failure itself the fire can increase the pressure of the extinguishing substance in the hose, which contributes to its quick release.
- the hose is disrupted at the temperature higher than 120 °C.
- the hose can be attached directly to the protected object, preferably by means of flexible stretching straps.
- the automatic fire extinguishing device does not need and does not have any electric or electronic component. This means that the moment of the opening of the hose cannot be communicated to the environment.
- the opening of the hose is accompanied by strong dynamic reaction; the leaking gas creates a force which tries to move the hose. In case the hose is not attached, it would have caused uncontrolled and in principle chaotic movement similar to the movement of free balloon with leaking air. Even in case of attachment of the hose a release of the extinguishing device, the hose moves and deforms in points of attachment during the release of the extinguishing substance.
- the pressurized hose can cause worries at the part of the personnel in the vicinity of the protected device.
- the hose is equipped by the thermometer. It is preferable of the thermometer without electronic assessment is used, for example a thermometer with thermochromic tinction (paint).
- the layer of the thermochromic tincion is applied onto the surface of the hose directly or by means of adhesive straps. Single- or multi-layer groupings of pigments from complex salts can be used.
- the change of the color points to the increased temperature which signals that the device may be activatd.
- the measuring of the temperature by means of a thermochromic tinction is reliable and does not require maintenance.
- the temperature is assessed on the surface of the hose, whereby it is precisely the surface of the hose which is necessary for the activation of the device.
- a pressure sensor can be attached to the hose, whose output is connected to the assessment unit, for example a panel of the fire protection unit. Sudden loss of pressure signals activation of the device; the hose therefore serves as a fire sensor, too.
- the device can be connected with electronic system, too.
- the hose can be equipped with the pyrotechnical element for sudden increase of the pressure.
- the hose has at least one place with weakened cross-section - for example, with suggested but incomplete perforation. After the manual start of the pyrotechnical element the hose is ripped up in the place with weakened cross-section and the extinguishing substance leaks to the environment.
- the hose can be equipped with outlet valve which is manually controlled, or with bimetal, or with memory metal (SMA) which at a give temperature opens the valve and the extinguishing substance is release to the outer space.
- SMA memory metal
- the invention has very simple and effective construction of the device where the coating of the hose itself forms not only a carrier and cover of the extinguishing substance, but it is also a detection element, whereby the detection of the presence of the flames results from the inherent features of the used material of the hose; thereby the detection ability of the device is unusually reliable and permanent.
- the device increases the efficacy of the fire protection.
- the automatic self-extinguishing fire device can be preferably used in transport technology. It can be placed in engine space where there is a risk of fire. The tests have proven that thanks to the dynamic effect during the ripping of the device even the small amount of extinguishing substance suffices to extinguish the fire.
- the hose is attached around the engine and in the vicinity of the components through which the fuel runs, or the hose can be simply attached to the engine bonnet.
- the advantage of the use of the automatic self-extinguishing fire device is its independence on the systems of the vehicle. Even in case of a crash, when the risk of fire increases and where the power supply is often disconnected, the automatic self-extinguishing fire device is still ready to extinguish.
- Automatic self-extinguishing fire device can be preferably used with electrical switchboards, server rooms, computer rooms and so on. In practice, the use proved advantageous mainly for spaces with available free volume smaller than 2m 3 .
- the device can be easily visually checked; the partially transparency of the hose allows to check the presence of the extinguishing substance which is a sign of its solidity and pressure. This prevents the unnoticed loss of pressure or leak of the extinguishing substance during the long-term presence of the hose at the place of the application.
- Figure 1 is a view of the automatic self-extinguishing device which has PVC protectors on its ends.
- Figure 2 is a hose with the remoed protecter; in the upper part there is a protector in the partial cross-section, in the lower part the protector is removed.
- Figure 3 is a detail of the hose with the ending which is pressed on the end of the hose and closed by the screw with a sealing.
- the automatic self-extinguishing fire device consists of polyamide hose 1 with a length at least 400 mm.
- the hose 1 can have such a length that it contains the necessary protected space and/or device.
- the polyamide hose 1. is partially transparent which allows to check the presence of the colored extinguishing substance 2 in it.
- the diameter of the hose in this example is 18 mm.
- the hose 1 there is an extinguishing substance 2 under pressure.
- On one end of the hose there is a tightly pressed ending 3 closed by the screw 4 and whole ending is equipped by heat- shrinking PVC protector.
- On the other end of the hose 1 hose there is a tightly pressed ending 3 closed by the screw 4 and whole ending is equipped by heat- shrinking PVC protector.
- These protectors ensure that small injuries related to manipulation with the device are avoided, and that the metal endings 3 do not harm sensitive objects in the vicinity of the mounting of the device.
- These protectors also indicate the integrity of the ends of the hose 1_.
- One end of the hose 1 is equipped by a pressure valve through which the extinguishing substance 2 is filled.
- Small manometer with the emergency pressure of the extinguishing substance 2 noted can be connected to the ending 3 in order to contorl the pressure.
- Manometer's diameter corresponds to the hose's 1. diameter.
- Automatic self-extinguishing fire device is attached horizontally or vertically or in other direction to the solid parts of the space or device which is to be protected from fire.
- the hose 1 cracks up and the extinguishing substance 2 gets to the seat of fire and it extinguishes the fire.
- the accesory to fire hose 1 is composed of 6 pieces of stretchable PVC straps thanks to which it is anchored at protected device and/or space.
- the softened polyamide wall of the hose 1 cracks up in the places of largest heat stress and it releases the extinguishing substance to the space. This effectively and reliably extinguishes even a budding fire.
- the extinguishing substance 2 can be solid, liquid or gas substance.
- the amount of the extinguishing substance 2 can be regulated by the length and diameter of the hose 1_. In the early stages the fire produces a heat which increases the pressure in the hose 1 which contributes to sudden punctual disruption of the integrity of the hose 1_.
- the outflowing extinguishing substance 2 has high flow rate and it targets large space.
- Automatic self-extinguishing fire device is placed in the engine of the bus.
- the hose 1. is attached in the vicinity of the device, it encircles its circumference and runs near the fuel pump and fuel filters.
- the automatic self-extinguishing fire device is placed in the electric switchboard of the flat house.
- the hose 1. of the automatic self-extinguishing fire device is inserted to the conveyor of the wooden pellets which transports the pellets into the boiler.
