Abstract

Mobile barrier against fires.

The Mobile Barrier Against Fires is intended for fight fires like interposition and brake.

Formed by masts of resistant material temperature that are joined by means of flame retardant material creating a Physical barrier to fire. The masts are hollow, they have a system of pipes or inner hoses, or are used as large pipes for the passage of water. It has two functions: Create one first barrier of interposition to fire and a secondary, Cool the masts and flame retardant material.

In each mast, facing the fire, openings with water outlets allow to create water areas pulverized as a curtain.

A top pipe-like bridge joins the masts It has a series of openings oriented upwards by those that pressurized water comes out. This water forms a curtain that Raise several meters above the barrier.

Description

Mobile barrier against fires.

The present invention relates to a system that physically interposes between a fire and an area or property to be protected. This prevents this last catch fire, either by direct action of the flames that come to it, either by the incendiary action of leaves, sparks or any other element capable of creating a fire that travels by air or land.

Background of the invention

The following devices are known: Hoses, firewalls and manual fire extinguishers.

Description of the invention

The Mobile Barrier Against Fires is a device intended for fire fighting with a passive character as of interposition and brake to the advance.

It is formed by metal or other masts temperature resistant material that are joined by means of a flame retardant material (preferably flexible, although it may be also rigid) creating a physical barrier that fire cannot pass immediately. The masts are hollow and either have an internal pipe or hose system, or its entire volume It is used as a large pipe for the passage of water. This water It has two functions: A main one, which is the creation of a first barrier of interposition to fire and a secondary that It consists of cooling the masts and the material flame retardant On each mast and on the face of it facing the several openings are located in which exits of water that allows to create areas of water sprayed as a curtain and which together cover the total surface of the barrier. By Lastly, an upper pipe-like bridge joins the masts. This it has a series of openings oriented upwards (with regulation variable, depending on the intensity of the wind) pressurized water. This water forms a curtain that rises several meters above the barrier, preventing any particles incendiary reach the target area.

Each mast has some sockets for the connection of hoses, which mainly come from motor pump trucks of Fire or fire extinguishing units. They could also be used by civilian personnel in their own homes using compressors of water to get an effective water curtain.

The whole device can be detachable for be easily transported in modules. Also to protect a large area, several barriers can be joined together by the material flame retardant

A variant could be the lack of apply the flame retardant fabric and make the barrier only with the curtain and Water spray

Another could be that if you do not have enough water pressure to create the curtain, from the bridge upper water can flow from the flame retardant fabric as a refrigerant to retard the action of fire.

A third variant could be the use of two ascending water curtains starting from two parallel pipes located at different heights.

This device is intended to be used. mainly for firefighting equipment in the field forest, being interposed between fire and houses, stables, barns, pens, cultivation areas, areas of valuable value, firewalls, warehouses, gas stations or as a guide for fire conduction But it can also be used in the field urban, protecting fuel storage areas or explosives, isolate fire zones in houses or prevent spread a fire to a neighboring property.

Brief description of the drawings

For the best understanding of all that remains written here, are accompanied by drawings in which a practical case study is approximated of the Mobile Barrier Against Fires.

In said drawings Figure 1 is a representation of the device where the following are distinguished Elements: The supports or masts (1) that support the set of the barrier, in which the frontal water outlets (1a) are located pulverized (4). These are joined by flame retardant material (2) and by some bridges (3), parallel to the ground and where we find the exits for the pressurized water curtain (3a).

Figure 2 represents a side view of the barrier and its interaction with respect to a house (6). In this one distinguish the barrier supports (1) and the fire retardant material that unites them (2). In addition there is the upper bridge (3).

From the front exits (1a) water comes out sprayed (4) at different heights and the top bridge (3) comes out a curtain of pressurized water (5). This is at its highest, taller than the total height of the house (6).

Figure 3 is a representation of the area of Barrier protection from a front view. In her we distinguish the supports or masts (1), with their frontal exits (1a) and the approximate area of coverage of the sprayed water (4); he flame retardant material (2), the upper bridges (3) and their outlets adjustable (3a) pressurized water (5).

Description of a preferred embodiment

The Mobile Barrier Against Fires is formed by the following elements:

Masts or structural supports (1). They are hollow prism-shaped pieces with different possible bases, but preferably circular or hexagonal. They are made of material lightweight and high temperature resistant (some type of metal) and it placed perpendicular to the ground, covering the highest possible height.  Its size is variable, depending on the height or extent of the area to protect.

Inside each mast (1) are placed pipes or hoses that lead to the outlets facing the fire (1st). In these a piece that allows spraying is coupled water and create a large area of protection. Hoses or pipes join in a common water outlet that caters to all Departures; This water comes from a motor pump or similar.

The masts are joined at the top by some pieces similar to these, but placed horizontally as a bridge (3). This one is endowed with some water outlets (3a) (connect to the same hose circuit or pipes that the frontal exits (1a), or they can have a own water outlet), which can be oriented by turning the entire piece (to adapt to wind and fire conditions), and that produce a high-pressure water curtain (5) intended to prevent the passage of any incendiary material that moves by air.

Another element that joins the masts (1) is the flame retardant material (2) that can be cloth, since it can be transport occupying less space than rigid materials. its fundamental objective is to act as a physical barrier against fire, and is reinforced by the water spray that creates a first defense barrier and refrigerates in addition to this material (2), Masts (1).

The entire device can be disassembled in modules for easy transport, but must be able to be mounted Fast and convenient way to reach the operational area.

Claims (2)

1. Mobile Barrier Against Fires with the main feature of retaining the advance of a fire as well as its propagation by air or land when it intervenes physically between the objective to protect and the fire itself. Has a structure formed by several supports or masts that join each other by means of fire retardant material that creates a physical barrier and by means of upper bridges that are tubular pieces parallel to the ground. 2. Mobile Barrier Against Fires, according to claim 1, characterized in that it has an internal water circulation system, through pipes or hoses, which allows a curtain to be created by the part of the fire-oriented masts. Water spray that flows through specific devices, and at the top of the bridge, a curtain of pressurized water that rises considerably above the structure to prevent the passage of incendiary particles by air.
