Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, specifically a composite fire hose with a protective mechanism. Background Technology

[0002] In firefighting operations, fire hoses are key equipment for transporting water for firefighting. However, traditional fire hoses are easily damaged by external forces such as being scratched by sharp objects, exposed to high temperatures, and run over by vehicles, leading to leaks and cracks, which affect firefighting efficiency and even endanger the safety of firefighters. At the same time, existing protective structures are mostly single-function and cannot meet the comprehensive protection needs of complex rescue scenarios. There is an urgent need to develop composite protection mechanisms to improve the reliability and durability of fire hoses.

[0003] Most existing fire hoses are directly connected to water nozzles for use. During use, the hoses are left on the ground for extended periods. Due to the urgency of firefighting operations, hoses are prone to being stepped on or accidentally bumped by objects at the fire scene, causing scratches and damage to the hoses. This affects the firefighting operation and may eventually lead to hose ruptures and breaks. The overall service life is relatively short, which seriously affects the firefighting operation. Utility Model Content

[0004] The purpose of this invention is to provide a composite fire hose with a protective mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a composite fire hose with a protective mechanism, comprising a fire hose, a water nozzle connecting mechanism at the left end of the fire hose, a fire hose protective mechanism on the surface of the fire hose, and a water nozzle at the left end of the fire hose;

[0006] The fire hose protection mechanism includes an inner reinforcing layer fixedly connected to the inside of the fire hose. An abrasion-resistant protective sleeve is installed on the surface of the fire hose, and abrasion-resistant reflective strips are fixedly connected to the surface of the abrasion-resistant protective sleeve. A detachable Velcro strap is fixedly connected to the surface of the abrasion-resistant protective sleeve. A fixing protective ring is fitted onto the surface of the fire hose, and a wear-resistant elastic silicone strip is fixedly connected to the inner end of the fixing protective ring. The fire hose body is made of wear-resistant and cut-resistant polyurethane material. This material has a smooth surface and a low coefficient of friction, reducing wear when the hose is dragged on the ground. It also has good cut resistance, preventing sharp objects from scratching the hose. The inner reinforcing layer is woven from high-strength polyester fibers. Polyester fibers have high strength and high modulus, enabling them to withstand greater pressure. Before use, the fire hose... Firefighters can install an appropriate number of abrasion-resistant protective sleeves on the surface of the fire hose as needed. These sleeves are made of aramid fiber, which possesses ultra-high strength, high modulus, and high-temperature resistance, effectively resisting abrasion and cut from ground sand, gravel, and sharp objects. The sleeves are secured to the fire hose surface with detachable Velcro, facilitating easy removal and replacement. The inclusion of abrasion-resistant reflective strips enhances visibility in low-light conditions, aiding firefighter identification and operation. Abrasion-resistant elastic silicone strips are designed at the bends of the fire hose. This flexible silicone adapts to the hose's bending deformation, protecting the bends from abrasion. This design significantly extends the service life and lifespan of the fire hose, while also facilitating easy disassembly and maintenance.

[0007] Preferably, the inner reinforcing layer is woven from high-strength polyester fiber, and the inner reinforcing layer and the fire hose are formed by hot pressing.

[0008] Preferably, the wear-resistant reflective strips are spaced apart along the length of the wear-resistant protective sleeve, and the detachable Velcro includes a rough side and a hook side, and the wear-resistant protective sleeve can be opened and closed by sticking the rough side and the hook side together.

[0009] Preferably, the fixing protective collar and the wear-resistant elastic silicone strip are installed at the bend of the fire hose, and the wear-resistant elastic silicone strip is made of a flexible material.

[0010] Preferably, the water nozzle connection mechanism includes a water nozzle mounting base, which is fixedly connected to the right end of the water nozzle. The surface of the water nozzle mounting base has an external thread, and the right end of the water nozzle mounting base has a mounting seat. The mounting seat has an internal thread, and a sealing sleeve is fixedly connected to the top of the mounting seat. A first mounting flange is fixedly connected to the right end of the mounting seat, and a second mounting flange is fixedly connected to the left end of the fire hose. A hose sealing sleeve is fixedly connected to the right end of the second mounting flange. The water nozzle mounting base and the mounting seat are connected together by the external and internal threads, and the fire hose is connected by the first and second mounting flanges. During use, the sealing sleeve and the hose sealing sleeve ensure a tight seal. This mechanism improves the stability and sealing of the connection, and enhances overall efficiency.

[0011] Preferably, the external thread and the internal thread are matched, the water gun head mounting base and the mounting base are threaded together by the external thread and the internal thread, and the mounting base and the fire hose are connected by the first mounting flange and the second mounting flange.

Polyester fiber has high strength and high modulus, and can withstand considerable pressure. Before use, firefighters can install an appropriate number of abrasion-resistant protective sleeves on the surface of the fire hose as needed. These abrasion-resistant protective sleeves are made of aramid fiber material, which has ultra-high strength.
