A multi-functional fire hose

Abstract

This utility model discloses a multifunctional fire hose, including a hose. The hose features a continuous array of arched protrusions in its anti-slip layer, periodically arranged along the hose's axis, providing multidirectional and continuous friction. This effectively reduces slippage when firefighters push, pull, or twist the hose, making the operation more reliable. The vents in the protective layer ensure good air permeability while preventing dust and debris from entering, providing reliable protection for the load-bearing layer. The first color-changing zone in the load-bearing layer, relying on an activated carbon adsorption layer and chemically sensitive capsules, can promptly indicate the presence of toxic gases. The second color-changing zone, aided by a conductive tape and a heat-sensitive capsule, can quickly indicate high-temperature areas. These two color-changing zones are staggered along the hose and, with the separation of spacers, achieve independent responses, avoiding interference between signals. This allows firefighters to quickly and accurately assess on-site risks, significantly improving the safety and overall efficiency of firefighting operations.

Description

Technical Field

[0001] This utility model relates to the field of fire hose technology, specifically a multifunctional fire hose. Background Technology

[0002] Fire hoses are key flexible pipes used in fire rescue to transport high-pressure water or flame-retardant liquids. They have a high-strength braided layer as the skeleton and are lined with water-resistant and pressure-resistant materials. They are flexible enough to be laid out flexibly and can withstand the impact of high-pressure water flow. They can efficiently deliver water to fire extinguishing equipment and build a life-saving and safe water supply channel at various fire scenes. They are important equipment for firefighters to quickly extinguish fires and control the spread of fire.

[0003] In existing technologies, when firefighters carry water hoses to carry out operations at a fire rescue scene, if they encounter a situation where there is no open flame and the core cause of the fire is not yet clear, they are prone to misjudgment due to the ambiguity of the fire information. Such misjudgment may lead to a mismatch between the rescue method and the actual fire situation. For example, they may mistakenly treat a fire involving reactive metals as an ordinary fire and directly inject water, which may trigger a violent chemical reaction that releases hydrogen and intensifies the combustion. Or, when faced with the combustion of organic peroxides and other chemicals that require special extinguishing agents, they may still insist on conventional water extinguishing. In the end, they may not only miss the golden time to choose the best solution to control the fire, but may also exacerbate the danger and increase the rescue risk. Utility Model Content

[0004] The purpose of this utility model is to provide a multifunctional fire hose to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional fire hose, comprising a hose, a first connecting pipe, a second connecting pipe, and a composite component. The first connecting pipe and the second connecting pipe are respectively connected to the front and rear ends of the hose. The composite component is disposed on the surface of the hose and includes an anti-slip layer, a protective layer, and a load-bearing layer. The load-bearing layer is attached to the surface of the hose, and a protective layer is disposed on the outside of the load-bearing layer. An anti-slip layer is disposed on the outside of the protective layer.

[0006] Preferably, the protective layer is provided with air vents evenly, and the air vents are distributed in an array along the circumferential direction of the water belt.

[0007] Preferably, the anti-slip layer adopts a continuous arched protrusion array design, which is periodically arranged along the water belt axis.

[0008] Preferably, the bearing layer includes a response layer, which is in close contact with the surface of the water hose. The response layer is provided with at least two sets of first color-changing areas, second color-changing areas and spacers inside, and the first color-changing areas and the second color-changing areas are separated by spacers to form independent response units. The tops of the first color-changing areas and the second color-changing areas are connected to the protective layer.

[0009] Preferably, the first and second color-changing zones in each group are staggered along the circumferential array of the water zone.

[0010] Preferably, each group of first color-changing zones is provided with an adsorption layer and a chemically sensitive capsule, while each group of second color-changing zones is provided with a heat-conducting tape and a thermochromic capsule.

[0011] Preferably, the materials of each adsorption layer and the heat-conducting tape are activated carbon and nylon, respectively, and they are respectively attached to the surface of the chemically sensitive capsule and the thermochromic capsule.

[0012] Preferably, the cross-section of each set of spacers is rectangular, and the width is consistent with that of the response layer.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model is equipped with an anti-slip layer. By adopting a continuous arched protrusion array and periodically arranging it along the axial direction of the hose, its structural design can significantly improve the operational stability during firefighting operations. The arched protrusions can provide multi-directional friction force. Whether firefighters are pushing, pulling or twisting the hose, the contact between their hands and the curved surface of the protrusions can form a stable force point, effectively reducing slippage.

[0015] This utility model is equipped with a protective layer. The air vents on the protective layer allow for ventilation while the small pores prevent dust and debris from entering the supporting layer, thus avoiding contamination or damage to the internal chemically sensitive capsules, thermochromic capsules, and spacers. This ensures the integrity of the main structure of the protective layer and maintains support and wear resistance for the supporting layer, preventing external abrasions from directly damaging the internal functional units, thus achieving a balance between ventilation and protection.

[0016] This invention features a support layer. The activated carbon adsorption layer in the first color-changing zone can quickly capture surrounding toxic gases, and the color-changing reaction of the chemical-sensitive capsule provides direct feedback on the risk of chemical leaks. The nylon conductive tape in the second color-changing zone can efficiently conduct ambient heat. The color change of the thermochromic capsule promptly indicates high-temperature danger areas. Combined with the full-width separation structure of the rectangular partition, the two color-changing zones are staggered along the hose, enabling independent responses and effectively avoiding mutual interference between thermal and chemical signals. This ensures the accuracy of the warning information, allowing firefighters to quickly assess on-site risks without relying on additional equipment, providing timely information for operational decisions, and further improving the safety and efficiency of firefighting operations.

Detailed Implementation

[0022] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0023] Please see Figures 1-3 This utility model provides a multifunctional fire hose, including a hose 1, a first connecting pipe 2, a second connecting pipe 3, and a composite component 4. The first connecting pipe 2 and the second connecting pipe 3 are respectively bolted to the front and rear ends of the hose 1. The composite component 4 is disposed on the surface of the hose 1 and includes an anti-slip layer 41, a protective layer 42, and a load-bearing layer 43. The load-bearing layer 43 is bonded to the surface of the hose 1 with hot melt adhesive. The protective layer 42 is disposed on the outside of the load-bearing layer 43, and the protective layer 42 is evenly provided with vent holes, which are distributed in an array along the circumference of the hose 1. This allows chemical substances and heat to be better transferred to the interior of the load-bearing layer 43 through the vent holes, and can prevent wear on the chemically sensitive capsule 4322 and the heat-discoloring capsule 4332. The anti-slip layer 41 is bonded to the outside of the protective layer 42, and the anti-slip layer 41 adopts a continuous arched protrusion array design, which is periodically arranged along the axial direction of the hose 1. This can increase the friction between the hand and the surface of the hose 1, effectively reduce slippage, and improve operational stability.

[0024] Please see Figure 4In this utility model, the bearing layer 43 includes a response layer 431, which is bonded to the surface of the water hose 1. The response layer 431 has at least two sets of first color-changing areas 432, second color-changing areas 433, and spacers 434 inside. The first color-changing areas 432 and the second color-changing areas 433 are separated by spacers 434 to form independent response units. The cross-section of each set of spacers 434 is rectangular, and the width is the same as that of the response layer 431. The purpose is to prevent the materials of the two areas from interfering with each other due to contact or diffusion, ensuring that their respective response signals are clear and independent, and improving the accuracy of risk judgment. The spacers 434 are made of PE, which has high rigidity and chemical resistance, and is lightweight. The tops of the first color-changing areas 432 and the second color-changing areas 433 are connected to the protective layer 42.

[0025] In this configuration, the first color-changing zone 432 and the second color-changing zone 433 of each group are staggered along the circumferential array of the water belt 1, so that the water belt 1 can respond quickly through the corresponding color-changing zone no matter which direction it comes into contact with toxic gas or high temperature environment, thus avoiding monitoring blind spots.

[0026] Each of the first color-changing zones 432 contains an adsorption layer 4321 and a chemical-sensitive capsule 4322, while each of the second color-changing zones 433 contains a heat-conducting layer 4331 and a thermochromic capsule 4332. The adsorption layer 4321 and the heat-conducting layer 4331 are made of activated carbon and nylon, respectively, and are attached to the surfaces of the chemical-sensitive capsule 4322 and the thermochromic capsule 4332. The activated carbon efficiently adsorbs toxic gases from the surrounding environment, allowing the gases to quickly come into contact with the chemical-sensitive capsule 4322 and trigger its color-changing reaction, thereby accurately reflecting the risk of chemical leakage. The nylon can quickly conduct ambient heat to the thermochromic capsule 4332, allowing the capsule to promptly indicate high-temperature areas through color changes.

[0027] Among them, the chemically sensitive capsule 4322 contains an acid-base indicator that reacts chemically upon contact with toxic gases, turning red in color. The thermochromic capsule 4332 contains a thermochromic material that changes its molecular structure and turns orange in color when exposed to high temperatures. The two capsules present distinctly different colors of red and orange, allowing users to quickly distinguish between toxic gases and high-temperature risks, intuitively perceive dangers in complex environments, and improve the efficiency and safety of emergency response.

[0028] Working principle:

[0029] First, when firefighters are carrying out firefighting tasks, they need to grab the water hose 1 and rush to the area that needs to be rescued. As the water hose 1 will inevitably get wet when spraying water, the continuous arched protrusion array of its anti-slip layer 41 is arranged circumferentially along the axis of the water hose 1, which effectively increases the friction between the hand and the surface of the water hose, reduces slippage, and improves the stability of operation.

[0030] Secondly, in the working environment, if there is a risk of toxic gases or high temperatures, the vents on the protective layer 42 allow chemicals and heat to be transferred to the interior of the supporting layer 43. At this time, the first color-changing zone 432 captures toxic gases through activated carbon, triggering the acid-base indicator reaction in the chemically sensitive capsule 4322, turning the color red. At the same time, the second color-changing zone 433 conducts ambient heat through nylon, causing the molecular structure of the thermochromic capsule 4332 to change due to high temperature, turning the color orange. Since the two sets of color-changing zones are distributed in an alternating array along the circumference of the hose and separated by rectangular spacers 434 to form independent response units, it is ensured that the two risk signals do not interfere with each other. Firefighters can quickly distinguish between toxic gas and high-temperature areas by the color change on the hose surface and take corresponding protective measures in a timely manner, improving the efficiency and safety of emergency response.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
