CZ12775U1 - Fire-extinguishing systems for conveyances, particularly for road, rail, caterpillar, suspended and water conveyances - Google Patents

Description

The technical solution concerns fire extinguishing systems for vehicles.

BACKGROUND OF THE INVENTION

At present, means of transport, in particular wheeled, rail, tracked, suspended and water vehicles, are equipped in the engine and / or transmission compartment, in the crew compartment and, in some cases, in the passenger compartment with a single-circuit fire extinguishing system. system with the possibility of manual initiation of the extinguishing process. In case of initiation of this system, the entire protected area is filled with extinguishing agent. The crew and passenger compartments are always equipped with at least one portable hand fire extinguisher.

The disadvantage of this solution is in case of manual and automatic start of the fire extinguishing system, especially in case of a small local fire, unnecessary use of extinguishing agent in the whole protected area, ie also in places where the fire would not spread in a timely intervention. Ultimately, the fire extinguishing action is unnecessarily expensive and the extinguishing medium also has an unnecessary effect on technological equipment not directly affected by the fire.

The essence of the technical solution

To a large extent, the proposed solution is based on the fact that, in a vehicle, each space which is wholly or even partially separated and contains devices that can potentially fire, is equipped with its own dual circuit fire extinguishing system, with one circuit it consists of fixed wiring with nozzles and the second circuit consists of a heat-sensitive hose with pressurized extinguishing medium, which is routed in the vicinity of those devices that can potentiate a possible fire.

Smoke and / or temperature sensors with initiation elements are located in each space.

These dual-circuit systems have a common control, control and evaluation unit and a central control and signaling panel located in the crew compartment.

In addition to the system, crew and passenger areas are equipped with at least one hand-held portable fire extinguisher.

In the event of a fire, the heat-sensitive hose reacts by melting, bursting and extinguishing the locally occurring fire at its origin. This fact is signaled through a signaling system on the panel in the crew compartment.

In the event of a fire spread, the fire is evaluated and signaled to the crew who manually initiate or, with a specified time delay, automatically initiate the extinguishing process using a circuit of fixed wiring and nozzles located in the area affected by the fire.

Exemplary embodiment

In a passenger transport vehicle with three separate compartments, engine and transmission compartment, crew compartment and passenger compartment, there are three extinguishing containers in the crew compartment, with one extinguishing container for one guarded area. The extinguishing vessels are fitted with pressure valves with electrical transmission.

Into each separate area is separately separated from its own extinguishing container, both a non-flammable distribution system with nozzles placed to cover the entire guarded area by its dispersion and also a distribution from heat-sensitive tubing, which is routed in places where devices that can potentiate fire.

Smoke and temperature sensors with initiation elements are located in each space.

These dual circuit systems have a common control, control and evaluation unit and a central control and signaling panel, which are located in the crew compartment.

Passenger and crew compartments are also equipped with one portable hand fire extinguisher.
