Description

PERFORATED FIRE HOSE TECHNICAL SECTOR The present invention falls within the field of safety and fire protection engineering, specifically in the sector of equipment and accessories intended for the conduction and distribution of water for firefighting, such as fire hoses. BACKGROUND OF THE INVENTION Fixed water curtain fire suppression systems are widely known in the state of the art, usually installed in infrastructure and buildings, which use rigid pipes and sprinklers to create a water barrier intended to limit the spread of fire. However, no perforated flexible hoses, configured for rapid deployment by emergency response teams to establish mobile control, defense, or self-protection lines for firefighters or other fire responders against fire spread, are known to exist. Likewise, no mobile systems have been identified that replicate the effect of a water curtain using a flexible hose designed to halt fire spread. In response to existing limitations in the field of technology, the present invention focuses on improving the existing state of the art, which lacks mobile, lightweight and adaptable solutions that allow responders to immediately generate a water barrier on the ground, especially in forest or structural fire scenarios where the mobility, speed and safety of fire responders in deployment are critical. EXPLANATION OF THE INVENTION The present invention introduces a perforated fire hose, comprising: a) an inner layer of rubber, b) an intermediate textile layer, c) an outer layer of rubber, where the hose has a plurality of through holes successively passing through the inner layer, the intermediate layer, and the outer layer. The hose of the present invention significantly improves firefighting techniques for firefighters and other fire responders. The extinguishing agent, such as water, can exit through the hose's orifices, forming a continuous, linear curtain that moistens the surrounding environment. This curtain acts, firstly, as a moist barrier that reduces the temperature of the fuel and protects the hose itself; secondly, it creates a moisture screen that hinders the spread of flames and their heat radiation; and finally, it creates a containment line that impedes or prevents the fire's advance. Furthermore, the hose of the invention offers additional advantages over traditional methods, as it does not require constant handling by the personnel involved, maintains uniform and continuous humidity, and allows covering a length equivalent to that of the hose itself, which can reach up to 25 m. Thus reducing the risk to the personnel involved. The hose of the invention, by having three layers instead of the four currently used by fire services, is lighter and can be deployed even by ground robots or aerial drones, thus creating a protection or defense zone on facades, garages or hazardous goods incidents, among others. BRIEF DESCRIPTION OF THE DRAWINGS To complement the description being made and in order to help a better understanding of the characteristics of the invention, a drawing is included as an integral part of said description, in which, for illustrative and non-limiting purposes, the following has been represented: Figure 1.- Shows a three-dimensional view of the perforated fire hose. PREFERRED EMBODIMENT OF THE INVENTION A detailed explanation of an example of a preferred embodiment of the semi-automatic turnstile of the present invention is then provided with the help of the figure referred to above. Figure 1 shows a perforated fire hose (1), comprising: a) an inner layer (2) of rubber, b) an intermediate textile layer (3), c) an outer layer (4) of rubber, where the hose (1) has a plurality of through holes (5) that successively pass through the inner layer (2), the intermediate layer (3) and the outer layer (4). If it had more layers, it would pass through all of them, since the goal is for the water to come out through the holes to create a curtain of water. In a preferred embodiment, the through holes (5) have a diameter between 0.5 mm and 3 mm, and are spaced between each other at a distance of between 30 cm and 60 cm. Fire hoses can be 20 to 25 m long with hose diameters of 25 mm and 45 mm respectively. In a preferred embodiment, the holes (5) are oriented radially with respect to the longitudinal axis of the hose (1). In a preferred embodiment, the holes (5) are arranged following a helical line around the surface of the hose (1). With these hole distribution options (5) along the hose, a uniform arrangement of holes is achieved. This allows for the uniform formation of a water or liquid extinguishing agent curtain when connected to a pressurized source of said agent, which is generally water. The materials used in the manufacture of the hose exhibit high fire resistance, as well as remarkable tolerance to exposure to hydrocarbons and excellent abrasion resistance, guaranteeing its structural integrity and reliable operation even in extreme conditions typical of fire scenarios. Thus, in a preferred embodiment, the inner layer (2) is made of nitrile rubber. This is highly advantageous because it minimizes pressure loss due to friction of the liquid extinguishing agent used. In another preferred embodiment, the intermediate layer (3) is a polyester or polyamide fabric, such as polyamide 66 (PA66), more commonly known commercially as nylon 66. In a final preferred embodiment, the outer layer (4) is made of nitrile rubber (NBR) or a mixture of nitrile rubber (NBR) and polyvinyl chloride (PVC). It may incorporate longitudinal grooves on its outer surface, which facilitate the movement of the hose (1) over uneven terrain, such as rocks or overgrown areas. Furthermore, this outer layer (4) may have a specific abrasion-resistant treatment with protective agents against ozone and ultraviolet rays.
