Abstract
Description
- This invention refers to fire fighting system field for the use in railway carriages.
- Actually the fire fighting safety in railway carriages is not fulfilled by any fixed extinguishing system. This situation, joined to the situation related to practical lack of fixed systems installed along the circulation railway, owing to its extension, can cause the obligation of using alternative safety systems that are greatly onerous for the collectivity such as, for example and not limited to this situation, the legal obligation of making a second parallel gallery used for emergency cases in tunnels having great lengths.
- The system forming the object of this description is a fixed system for fire fighting protection based on the delivery of nebulized water, specifically projected for the control, cutting off or extinguishing of fire in the field of railway carriages.
- For a better comprehension of this invention and for showing how the same can be applied, it shall be made reference, as an example, to the annexed drawings, in which:
- Figure 1 shows a functional scheme of the various parts of the system and of its various components;
- Figure 2 shows a typical layout of a real installation, that can be made economically.
- The Figure 1 shows schematically the layout of the various parts of fire fighting system in a railway carriage, joined by quick coupling flexible pipes to the adjacent carriages, so that the systems normally used in these carriages can be employed.
- With reference to the typical scheme (see Figure 1) and to the typical layout scheme (see Figure 2), the system is made-up of a series of
bombs 1 holding drinkable and/or demineralized water, a nitrogen bomb for pressurizing and delivering water into theline 2, aspecial device 3, that can be remotely controlled, for spraying water in the zones in which it is required the delivery, a pipe network 4 and finally a series ofdelivery nozzles 5. Thedelivery nozzles 5 are normally concealed into the internal bulkheads for the carriage completing and, during the intervention, they are automatically extracted from the bulkheads using a telescopic mechanism. The nozzles are made in different types: some thereof have the aim of suppressing and extinguishing fires, other ones, located in suitable positions, have the aim of separating smoke zones and shielding the heat transmitted by thermal irradiation and convection. Using a series of 3-way shunting valves 3, it is possible to select the delivery zone, as in the front side of the carriage, in the rear side or in one of the two carriage halves, in which the bombs are installed, or in a third half of adjacent carriage using a high pressure flexible pipe quick coupling. In this manner it is possible to avoid the water delivery where it is not necessary, but delivering it only in the whished fire zone and then being able to double the autonomy in each carriage half and, then, to reduce to a half the weights and overall dimensions of the bomb series keeping constant the autonomy and costs related to it. - The
nozzles 5 cannot be removed, as they are concealed by a control inside the internal carriage wall. A hydraulic telescopic mechanism allows the ejection of nozzles for operation and return to rest position after having used the system. - The control mechanisms for the nitrogen bomb and water bombs are well-known, and then they are not discussed in further details.
- The carriage ceiling has a double bottom with thermosensitive cable that detects the presence of excessive temperature higher than a certain danger threshold and with control circuits that, in relation to this temperature signal, control automatically the delivery start-up in the fire zone. As an alternative the control can be started manually by other controls, under the control of chief conductor or other service controller.
- Figure 2 shows a typical layout of a real installation, that can be made economically. This figure shows the
water bombs 1 A andnitrogen bombs 2A, thedistribution valves 3A that shunt the water in the carriage holding the bomb series or in the adjacent carriage joined by thequick coupling 7A. The line 4A distributes the water into thenozzles 5A and in detail also in the central carriage zone into the nozzles 6A for generating an anti-smoke curtain. - The fire fighting system can be operated by remote control in the inside of railway train or by the manual control from the carriage. The remote control, on its turn, can be piloted in automatic manner by a suitable detection system (e.g., but not solely, thermal detection systems, smoke, flame detection systems, etc...) or in manual manner by an operator, eventually after that he has received an alarm signal using proper pushbuttons, by closed circuit television (TVCC) or by automatic detectors. The action of fire fighting system is to deliver thin water particles, no dangerous for the people or for things, which cuts off or extinguish á fire by the following mechanisms:
- Thermal absorption and following temperature reduction,
- Dilution of oxygen percentage near the flame by steaming and following production of water steam,
- Reduction of energy irradiation heat transmission owing to the numerous water drops that are produced.
- These fire fighting systems are normally offered on the market, but they are not provided on railway carriages owing to various problems, mainly to related costs.
- The system advantages with respect to the actual solution applied in railway carriages are the following ones:
- 1. Safety for persons. The carriage is supplied with a fire extinguishing system that is not dangerous for persons and can increase notably the survival probability in the case of this event;
- 2. Safety for things;
- 3. Localized and immediate protection, that is to say it is present where it occurs, on the train, and not externally to it on the circulation railway.
This causes a spare in the costs of safety systems; - 4. Further spare applying the passive structural safety rules (e.g. in tunnel parallel to the one of normal use for traffic).
- The main advantages of the invention system with respect to normal known systems are:
- 1. Separation of zones holding smokes and zones at high temperatures, made-up in the middle of carriage owing to innovative water blade spraying nozzles.
- 2. "Selective" delivery system in many zones. Thanks to a new shunting three-way valve it is possible to select the delivery zone, or one of the two halves of carriage, in which bombs are contained or a third half of adjacent carriage owing to a high pressure flexible pipe quick coupling. In this manner it is possible to double the autonomy of each half carriage and, then, to reduce to a half the weights and overall dimensions of bomb series, keeping constant the autonomy and costs thereof.
- 3. The nozzles cannot be tampered as they disappear in the inside of internal carriage wall. A new hydraulic telescopic mechanism allows its ejection for the operation and return to the rest position after operation.
Although this invention was described with reference to its particular embodiments, many other variants and modifications and other uses shall be evident to the people skilled in the technics.
