    CAPSULE FOR FIRE PROTECTION AND PROCEDURE FOR CREATING A SAFETY STRIP

    DESCRIPTION
     5
    Object of the invention
    The present invention relates to a fire capsule that disperses an extinguishing product in a controlled manner over its environment, moisturizing it and reducing the intensity of a fire that could affect it. The capsule has an activation mechanism without electrical and / or electronic elements, so that its duration in an adverse environment, such as the field, is high, and that it can be installed in terrestrial environment and in an air environment interchangeably, additionally to this, the capsule object of the invention also lacks pyrotechnic means for expanding the extinguishing agent, making it a totally safe device.
    The capsule object of the invention is applicable in the fire prevention and extinguishing industry, more specifically of forest fires.

    Technical problem to solve and background of the invention
    Forest fires are one of the biggest problems affecting today's society, causing significant personal, material and environmental damage. Due to both climate change, and the increase in urban forest interface areas where the urban area is prioritized over forestry, its incidence is expected to be aggravated.

    There are multiple tools included in the activities of prevention and extinction of forest fires that are aimed at minimizing the number of 25 fires as well as reducing their effects. There are large devices for extinguishing forest fires, but further development of prevention measures is necessary, which allows extinction resources to work more safely and effectively.

    One of the main protection and prevention measures currently used is the creation of barriers to the passage of fire. These barriers are mainly executed by creating areas where the amount of fuel available to burn is reduced, with the aim of creating strips of land to reduce or stop the progress of the fire. Currently, two methodologies to create these infrastructures stand out, such as the elimination of fuel (such as a firewall area) or the creation of a wet line that prevents or limits the combustion of vegetation.
    These actions have a series of limitations that hinder their execution or limit their effectiveness. On the one hand, traditional firewalls, executed to create discontinuities in the forest mass, imply a high environmental impact, especially landscape, by subtracting surrounding vegetation, in addition to certain environmental regulations that may limit their execution, both spatially and temporarily. Similarly, many times it is complex to be able to achieve the availability of the land for execution. On the other hand, these infrastructures require a lot of time for their execution and continuous maintenance.

    Regarding the creation of wet lines, there are different forms of execution, such as 10 are by air means during extinction tasks, by pumper trucks, used both in prevention and extinction work or through the existence of a network of hydrants / sprinklers that allows you to generate this wet strip. These systems, which can be used in combination with a fuel disposal, have their limitations. fifteen

    Another problem, especially associated with the use of aerial means, is the irregular distribution of the retardant on the vegetation, which determines its effectiveness, as well as the inconveniences of application of the retarding products, mainly related to corrosion aspects. In the case of hydrant or cannon networks, they have a high installation cost, high energy requirements and little flexibility if they are fixed installation.

    Another way to create defense lines, used only in extinction, is through the use of explosion extinguishers (such as the one disclosed in document ES 2 026 393 A6), 25 although its use was limited by the risks associated with its use and collection .

    Document ES 2 414 304 A1 is also known, which discloses a self-protection system against forest fires in an urban forest interface, where a plurality of system provisions for protecting an urban area or individual buildings 30 are disclosed by creating a protection zone. around the area to protect.

    Preferred Embodiment of the Invention
    As already indicated, and as can be seen in the figures, the object of the invention is a fire capsule comprising a container (1) that houses at least one extinguishing agent, compressed gas and an activator (2) to activate the release of the extinguishing agent with characteristics of durability and stability that until now did not exist, and that lacks explosive elements for said release, being a totally safe system.

    The activator (2) of the capsule object of the invention comprises a valve (3), a diffuser (4) and a thermal sensor (5). 25

    The valve (3), in the preferred embodiment of the invention, comprises a body (6) with an inner chamber (7) with an upper stop (8), where a thermal actuator (9) is located that houses a liquid sensitive to the heat inside and a cylinder (10) attached to the thermal actuator (9), such that in the closed position, the thermal actuator (9) is in contact with the upper stop 30 (8), and such that the thermal actuator ( 9) is configured to break due to a temperature rise that affects the heat-sensitive liquid, and when the thermal actuator (9) is broken, the cylinder (10) is released, which moves inside the chamber (7) until the cylinder (10) contacts the upper stop (8) of the chamber (7), allowing the extinguishing agent to leave the container (1) and dispersing said extinguishing agent through the diffuser (4).

    The cylinder (10) of the valve (3) has a filling channel (11) which is a through hole along the cylinder itself (10) that allows, by connecting the capsule to a pressure line, to pressurize the capsule object of the invention introducing air through said filling channel (11). 5

    In the preferred embodiment of the invention the thermal actuator (9) is a glass thermal bulb that houses the heat sensitive liquid, so that this thermal actuator (9) has a high compressive strength and a calibrated breaking temperature . At the moment when the temperature in the vicinity of the thermal actuator (9) rises, the heat-sensitive fluid begins its expansion until the breakage of the bulb occurs by shear, at which time the cylinder (10) is free , it moves inside the chamber (7) and the opening of the valve (3) and the dispersion of the extinguishing agent occurs.

    Although the preferred embodiment of the thermal actuator (9) is the bulb, said thermal actuator 15 (9) can be any device or part that loses its mechanical characteristics due to the temperature, for example a plastic cylinder that by the temperature action It modifies its plasticity module and is broken by the pressure of the cylinder pressure (10).
     twenty
    The capsule object of the invention has an alternative embodiment in which the activation is manual, to perform that manual activation the valve (3) comprises a ring (12) around the thermal actuator (9) configured so that in an extraction movement of the ring (12), break the thermal actuator (9) and release the cylinder (10) to open the valve (3) manually. 25

    There are two embodiments of the activator (2):
    - a first embodiment in which the diffuser (4) is an independent part of the thermal sensor (5), and
    - a second embodiment in which the diffuser (4) forms a unit piece with the thermal sensor (5).

    The diffuser (4), in the two embodiments of the invention, comprises a plurality of openings (13) for dispersion of the extinguishing agent. Furthermore, with a view to correctly directing the dispersion of the extinguishing agent, in correspondence with the plurality of openings (13) of the diffuser (4), the capsule object of the invention has a plurality of
    diffusion mouths (14) placed in said openings (13).

    In addition, the valve (3) comprises a plurality of outlets (15) located in the perimeter of the chamber (7), to communicate the chamber (7) with the openings (13) of the diffuser (4) and, when the valve (3 ) it is open to allow the exit of the extinguishing agent from the container 5 (1), so that the exit of the extinguishing agent from the container (1) is produced only by the plurality of outlets (15) of the perimeter of the chamber (7).

    To ensure that, in case of fire, the heat generated by the fire is directed towards the thermal actuator (9), the activator (2) has the thermal sensor (5) which is a 10 element designed to capture and direct the air currents towards the thermal actuator (9) of the valve (3), thus the thermal collector (5) comprises a set of fins (16) to capture horizontal air currents and a concave surface (17) to capture a current of rising air (see figures 10 and 11).
     fifteen
    In the embodiment in which the diffuser (1) is an independent part of the thermal sensor (5), said diffuser (4) comprises a plurality of grooves (20) configured to accommodate the set of fins (16) of the thermal sensor ( 5) and thus fix the thermal sensor (5) on the diffuser (4).
     twenty
    To ensure the correct orientation of the thermal sensor (5) on the valve (3), the diffuser (4) has at least one flange (18) that has its corresponding housing (19) on the valve (3).

    The activator (2) comprises a unidirectional valve (21) located between the valve (3) and the container (1) configured to allow air to enter the container (1) and prevent its exit, that unidirectional valve (21) allows , collaborating with the filling channel (11) of the cylinder (10) pressurizing the capsule object of the invention by introducing air through said filling channel (11), and even using this filling channel (11) to fill the container (1 ) with the extinguishing agent. 30

    The container (1) of the capsule object of the invention houses inside it an extinguishing agent and compressed gas.

    The container (1) comprises a tube (22) comprising a mouth at the end of the tube 35 (22) located in correspondence with the bottom of the container (1), so that when
    produces the opening of the valve (3) the exit of the extinguishing agent occurs and not of the compressed gas, therefore the tube (22) is necessary when the capsule object of the invention is used in soil, however when the capsule object of The invention is used aerially, said tube (22) is not necessary.
     5
    The spray angle of the extinguishing agent is defined by the orientation of the diffusion mouth (14) with respect to the diffuser (4), so, depending on the type of diffuser that is placed in the capsule, a diffusion mouth ( 14) more or less inclined.

    In order to ensure that all the joints between the different elements of the activator (2) are 10 sealed joints, the activator (2) comprises a plurality of O-rings (23).

    The container (1), to facilitate fixing the activator (2) on the container (1), comprises a neck (24) which in turn comprises a thread (25) so that the valve (3) of the activator (2) ) it is threaded to the neck (24) and to seal the aforementioned union between the activator (2) 15 and the container (1) a flat gasket (26) and an adjustment piece (27) are used that is inserted into the neck ( 24) and fits the valve (3).

    Finally, since there are two ways of placing the capsule object of the invention, an aerial one, located hooked or hung on vegetation (or another element) and another, supported on the ground, the capsule object of the invention can comprise an element of hook in vegetation (28) in the form of a ring or similar, and to place the capsule on the ground and that is stable, it can also comprise legs (29) fixed to the container (1). In addition to transporting from one site to another, the capsule object of the invention comprises a handle (30) attached to the container (1) through an ear (33) located in the container (1), so that the handle (30) can be removed from the container (1) by means of a pin (31) inserted in the lug (33).

    The capsule object of the invention, by placing and orienting the diffusion nozzles (14) on the diffuser (4), optimizes the spray form of the extinguishing agent 30 on the fire, and creates barriers and screens to protect specific areas of the fire. In the capsule object of the invention according to the number of diffusion mouths (14) and the angles associated therewith, when activated, each capsule generates a certain footprint (32) of product on the ground, and to create a protective barrier the different capsules are arranged and a fingerprint (32) is generated, which is the sum of the fingerprints (32) of each 35 capsule. That is, by placing a plurality of capsules as defined.
    before, it is possible to create a zone or a strip of protection (36) around an area that one wishes to protect, since it is possible that the fingerprints (32) of some capsules are added to the prints (32) of other capsules, with overlap zones (35) between fingerprints (32) thus creating the said protection zone or strip (36).
     5
    Likewise, the device object of the invention can be used remotely, since it allows its use by remote launching with launchers such as those referred to in ES2326013B1, or throwing it from the air for which it incorporates a parachute (34) that allows to reduce its speed of drop.
