The outer surface of the pressure-resistant layer 31 is coated and bonded with a heat-insulating layer 32. The heat-insulating layer 32 is made of glass fiber, which has good heat-insulating performance to reduce the impact of high temperature in the fire scene on the rubber lining 1. A detachable protective layer 33 is arranged on the outside of the heat-insulating layer 32.

[0024] To further explain, the outer surface of the thermal insulation layer 32 is coated with a weather-resistant layer 321 . The weather-resistant layer 321 is made of silicone rubber coating. The weather-resistant layer 321 has the characteristics of high strength, high temperature resistance, high corrosion resistance, good weather resistance, and wear resistance, which effectively improves the weather resistance of the thermal insulation layer 32 .

[0025] See also Figure 3-4In the present invention, the two sides of the detachable protective layer 33 are respectively provided with a hook surface 331 and a fleece surface 332. The hook surface 331 and the fleece surface 332 are Velcro structures in the prior art. The hook surface 331 can be bonded to the surface of the fleece surface 332, so that the detachable protective layer 33 is rolled into a tube shape. The detachable protective layer 33 is sleeved and covered on the outside of the heat insulation layer 32. The detachable protective layer 33 is more easily worn and consumed as the outer protective structure of the fire hose. After the durability of the detachable protective layer 33 is exhausted, It can be removed and replaced separately to reduce replacement costs. The surface layer of the removable protective layer 33 is a wear-resistant layer 333. The wear-resistant layer 333 is made of nylon fiber material, which has excellent wear resistance and tear resistance, so that the fire hose is not easy to wear and break when dragged on the ground. The inner layer of the removable protective layer 33 is a puncture-proof layer 334. The puncture-proof layer 334 is made of aramid fiber material, which has excellent impact resistance, cut resistance and puncture resistance, and prevents the rubber lining 1 from being scratched or punctured by sharp objects on the ground to cause leakage.

[0026] See also Figure 5 In the present invention, a positioning mechanism 34 is provided on the outer surface of the heat insulating layer 32 and the inner wall surface of the removable protective layer 33, and the positioning mechanism 34 includes a strap 341, a binding strap 342, a sub-button 343 and a female buckle 344.

[0027] It is further explained that the number of positioning mechanisms 34 is not less than 2, and the positioning mechanisms 34 are equidistantly distributed on the outer surface of the insulation layer 32 and the inner wall of the removable protective layer 33 to ensure the positioning effect of the removable protective layer 33, so that the removable protective layer 33 is not easy to slide away from the outside of the insulation layer 32 by itself.

[0028] Here’s how it works:

[0029] First, by coating the inner wall of the rubber lining 1 with the water-resistant layer 2 , the water-resistant layer 2 can enhance the waterproof and corrosion resistance of the rubber lining 1 , thereby improving the durability of the rubber lining 1 .

[0030] Second, a multifunctional protective structure 3 is provided on the outside of the rubber lining 1, and a pressure-resistant layer 31 is coated and bonded on the outer surface of the rubber lining 1. The pressure-resistant layer 31 is made of polyester fiber, which has high strength and stability to improve the pressure resistance of the rubber lining 1.

[0031] Third, a detachable protective layer 33 is provided outside the heat-insulating layer 32, and the surface layer of the detachable protective layer 33 is a wear-resistant layer 333. The wear-resistant layer 333 is made of nylon fiber material, which has excellent wear resistance and tear resistance, so that the fire hose is not easy to wear and break when dragged on the ground. The inner layer of the detachable protective layer 33 is a puncture-proof layer 334. The puncture-proof layer 334 is made of aramid fiber material, which has excellent impact resistance, cut resistance and puncture resistance, and prevents the rubber lining 1 from being scratched or punctured by sharp objects on the ground to cause leakage. In addition, the detachable protective layer 33 as the outer protective structure of the fire hose is more susceptible to wear and consumption. After the durability of the detachable protective layer 33 is exhausted, it can be removed and replaced separately to reduce the replacement cost.

[0032] Fourth, when installing the removable protective layer 33, first wrap the removable protective layer 33 around the surface of the thermal insulation layer 32, then pass the end of the binding strap 342 through the drawstring 341 and fasten and fix it with the sub-buckle 343 and the female buckle 344, so that the binding strap 342 and the drawstring 341 fit together, thereby fastening the removable protective layer 33 to prevent it from slipping by itself, and then the two side edges of the removable protective layer 33 are fitted together through the hook surface 331 and the fur surface 332, so that the removable protective layer 33 is wrapped around the surface of the thermal insulation layer 32, and the installation of the removable protective layer 33 is completed.

The abrasion resistance and tear resistance make the fire hose not easily worn and broken when dragged on the ground. The inner layer of the detachable protective layer 33 is the anti-puncture layer 334. The anti-puncture layer 334 is made of aramid fiber material, which has excellent impact resistance, cut resistance and puncture resistance, and prevents the rubber lining 1 from being scratched or punctured by sharp objects on the ground to cause leakage. A positioning mechanism 34 is set on the outer surface of the insulation layer 32 and the inner wall of the detachable protective layer 33. The end of the strap 342 is passed through the strap 341 and fastened and fixed with the female buckle 344 through the sub-buckle 343, so that the strap 342 and the strap 341 are fitted together, so as to tie the detachable protective layer 33 to prevent it from slipping by itself.
