Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of fire fighting equipment, and in particular relates to an intelligent fire fighting hose. Background Art
[0002] Fire hoses are commonly used firefighting equipment for large and medium-sized fires. Both ends of the fire hose have interfaces, which are connected to fire hydrants and water guns respectively. Ordinary fire hoses are used to spray the fire source with a water gun to extinguish the fire until the fire is completely extinguished. When extinguishing a fire, the fire source is generally sprayed with a water gun while holding the hose. When the fire source near the outside is extinguished, the fire source moves to a deeper position and continues to extinguish the fire inside. However, when firefighters or firefighters walk inside to extinguish the fire, the previously extinguished fire source outside may reignite, resulting in a failure in extinguishing the fire. In addition, the reignited flames will cut off the firefighters' retreat route, seriously threatening the lives of the firefighters. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0028] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.
[0029] Please refer to Figure 1-5 This embodiment provides an intelligent fire hose, including a hose 1, joints are provided at both ends of the hose 1, and a guide pipe 2 is provided on the outer pipe wall of the hose 1.
[0030] The wall of the guide pipe 2 is provided with a plurality of water spray holes 7, and the water spray holes 7 of the guide pipe 2 are provided with an atomizing device 5. The outer wall of the water hose 1 is provided with a sensing device. In this embodiment, the guide pipe 2 is made of thermoplastic polyester elastomer, which has excellent elasticity and heat resistance. TPEE can quickly recover to its original state after being stressed, and has good tensile and tearing strength. It can maintain its physical properties and elasticity in a high temperature environment.
[0031] The outer layer of the fire hose 1 is provided with a smooth layer, and the material of the smooth layer is polytetrafluoroethylene, which is a polymer material with an ultra-low friction coefficient. Due to its very smooth surface characteristics, objects are subject to very little resistance when moving on its surface. Therefore, using polytetrafluoroethylene to make the smooth layer of the fire hose 1 can reduce the friction between the fire hose 1 during use, thereby preventing the fire hose 1 from being entangled and knotted due to improper operation or unreasonable storage methods during use.
[0032] In this embodiment, the guide pipe 2 is connected to the water hose 1 by gluing, and the sensing device is connected to a control device 6 arranged on the outer wall of the water hose 1, and the control device 6 includes a power supply and a control circuit. In this embodiment, the sensing device includes a temperature sensor 8 and a buzzer 9, and an atomizing device 5 is arranged at the water spray hole 7. The atomizing device 5 can atomize the liquid in the guide pipe 2 into water mist, and this water mist has a strong heat absorption and cooling ability. This is because the surface area of the water mist is large, the time required for vaporization is short, and the heat absorption efficiency is high, so it can quickly absorb and take away the heat from the surface of the burning material or the fire area, so that the surface temperature of the material drops rapidly, thereby interrupting thermal decomposition and terminating combustion.
[0033] Secondly, water mist can also produce the effect of oxygen isolation and suffocation. The small mist droplets vaporize to form a large amount of water vapor after being heated, which can repel and squeeze out the air in the fire scene to the maximum extent, reduce the oxygen content around the burning objects, and inhibit or interrupt the combustion due to lack of oxygen.
[0034] In addition, water mist fire extinguishing has good insulation properties and can extinguish electrical fires, etc. Water mist evaporates when it encounters fire, leaving little water stains and no effect on electronic components. At the same time, the characteristics of water mist can be used to clean and flush toxic gases such as smoke, improve visibility at the fire scene, and facilitate personnel evacuation and firefighting and rescue by firefighters.
[0035] Please refer to Figure 2 In this embodiment, there are two joints, wherein the first joint 3 corresponds to the guide pipe 2, and the second joint 4 corresponds to the water hose 1. During the firefighting operation, the second joint 4 is connected to the fire hydrant. The first joint 3 is connected to the water gun, wherein the joint and the water gun are standard parts in the firefighting field, and the specific installation process is not described here.
[0036] The utility model provides a guide pipe 2 on the outer pipe wall of the water hose 1. During the process of unfolding and reeling the water hose 1, the guide pipe 2 will play a directional role to ensure that the water hose 1 moves along a predetermined path, thereby avoiding crossing or entanglement.
[0037] The utility model can monitor the temperature near the water hose 1 in real time during the fire extinguishing process by arranging a sensor and an alarm device on the outer wall, and turn on the buzzer 9 to alarm when the external temperature is too high, so as to ensure the personal safety of the fire extinguishers.
[0038] The utility model provides an atomizing device 5 at the water spray hole 7 to generate water mist near the water hose 1 to reduce the temperature around the water hose 1 during the fire extinguishing process, and can also exclude and squeeze out the air in the fire scene to the maximum extent, reduce the oxygen content around the burning object, and suppress or interrupt the combustion due to lack of oxygen, so as to ensure the normal progress of the fire extinguishing operation and the safety of the rescue personnel's return journey.
[0039] The utility model reduces the friction force on the surface of the water hose 1 by arranging a smooth layer on the surface of the water hose 1, thereby avoiding the situation where entanglement and knotting due to improper operation or unreasonable storage method seriously affects the rescue efficiency.
