Description

Technical Field

[0001] The utility model relates to the technical field of fire hoses, in particular to a highly flame-retardant and fireproof fire hose. Background Art

[0002] A fire hose is a flexible pipe used to transport high-pressure water or flame-retardant liquids such as foam. Traditional fire hoses are lined with rubber and covered with woven linen. Advanced fire hoses are made of polymer materials such as polyurethane. Both ends of the fire hose have metal connectors that can be connected to another hose to extend the distance or to a nozzle to increase the pressure of the liquid spray.

[0003] At present, fire hoses are usually dragged on the ground during use. Since the hose is in direct contact with the ground, on the one hand, the bottom of the hose is severely worn. On the other hand, the friction between the hose and the ground is large, making it difficult for firefighters to drag the hose, affecting the firefighting work.

[0004] Therefore, it is necessary to provide a new high flame retardant fireproof fire hose to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a highly flame retardant and fireproof fire hose.

[0006] The highly flame-retardant and fire-resistant fire hose provided by the utility model comprises:

[0007] belt body, and

[0008] An elastic bottom bag is fixedly embedded in the bottom of the belt body, and both sides of the elastic bottom bag are provided with an integrally formed elastic stretchable pleated section. The bottom of the elastic bottom bag is fixedly embedded with a flame-retardant polyester braided layer, and the bottom of the flame-retardant polyester braided layer is opened and installed with a number of evenly distributed and rotatably connected plastic balls;

[0009] A one-way water inlet valve and a one-way water drain valve communicated with the elastic bottom bag are respectively installed on both sides of the belt body.

[0010] Preferably, a plurality of equally spaced arc-shaped elastic sheets are fixedly embedded on the upper belt surface of the belt body.

[0011] Preferably, both ends of the belt body are fixedly embedded with connecting pipe heads.

[0012] Preferably, the belt body includes a rubber layer, an extended braided layer is fixedly embedded on the outer surface of the rubber layer, an asbestos flame retardant layer is fixedly embedded on the extended braided layer, a heat-resistant layer is fixedly embedded on the outer surface of the asbestos flame retardant layer, and a wear-resistant layer is fixedly compounded on the heat-resistant layer.

[0013] Preferably, the heat-resistant layer is composed of a cross-linked polyethylene layer and a low-smoke halogen-free flame-retardant polyolefin layer of an inner and outer composite structure.

[0014] Preferably, the wear-resistant layer is made of toughened aluminum oxide material.

[0015] Compared with related technologies, the highly flame-retardant and fire-resistant fire hose provided by the present invention has the following beneficial effects:

[0016] In the present invention, when water enters the belt body, part of the water enters the elastic bottom bag through the one-way water inlet valve, so that the elastic stretchable pleated sections on both sides of the elastic bottom bag are extended and the elastic bottom bag is expanded. Since the expanded elastic bottom bag is an elastic structure, the elastic bottom bag improves the pressure bearing capacity of the belt body on the one hand, and reduces the wear of the bottom of the belt body on the other hand. The plastic balls arranged at the bottom of the flame-retardant polyester braided layer greatly reduce the friction between the belt body and the ground, which not only makes it easier for firefighters to drag the belt body toward the flame, but also further reduces the wear between the belt body and the ground.

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0025] See also Figures 1 to 5 The embodiment of the present invention provides a highly flame-retardant and fire-proof fire hose, which includes a belt body 1 and an elastic bottom bag 2.

[0026] In the embodiments of the present invention, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The bottom of the belt body 1 is fixedly embedded with an elastic bottom bag 2, and the bag surfaces on both sides of the elastic bottom bag 2 are provided with integrally formed elastic telescopic pleated sections 21. The bottom of the elastic bottom bag 2 is fixedly embedded with a flame-retardant polyester woven layer 22, and the bottom of the flame-retardant polyester woven layer 22 is opened and installed with a number of evenly distributed and rotatably connected plastic balls 3. A one-way water inlet valve 5 and a one-way drain valve 6 connected to the elastic bottom bag 2 are respectively installed on both sides of the belt body 1, and connecting pipe heads 7 are fixedly embedded at both ends of the belt body 1.

[0027] It should be noted that when in use, the connecting pipe head 7 on the belt body 1 adjacent to the one-way water inlet valve 5 is connected to the fire hydrant connection end, and the connecting pipe head 7 on the belt body 1 adjacent to the one-way drain valve 6 is connected to the fire extinguishing spray gun, so that water can enter the elastic bottom bag 2 through the one-way water inlet valve 5 and flow back to the other side of the belt body 1 through the one-way drain valve 6 on the elastic bottom bag 2;

[0028] When water enters the belt body 1, part of the water enters the elastic bottom bladder 2 through the one-way water inlet valve 5, thereby extending the elastic and retractable pleated sections 21 on both sides of the elastic bottom bladder 2 and causing the elastic bottom bladder 2 to expand. Since the expanded elastic bottom bladder 2 has an elastic structure, the elastic bottom bladder 2 not only improves the pressure bearing capacity of the belt body 1, but also directly avoids wear on the bottom of the belt body 1.

[0029] The plastic balls 3 provided at the bottom of the flame-retardant polyester braided layer 22 greatly reduce the friction between the belt body 1 and the ground, which not only makes it easier for firefighters to drag the belt body 1 toward the flames, but also further reduces the wear between the belt body 1 and the ground.

[0030] The upper surface of the belt body 1 is fixedly embedded with a plurality of equally spaced arc-shaped elastic sheets 4, which effectively protect the belt body 1.

[0031] In the embodiments of the present invention, please refer to Figure 1 and Figure 5 The belt body 1 includes a rubber layer 101, and the outer surface of the rubber layer 101 is fixedly embedded with an extended braided layer 102, and the extended braided layer 102 is woven from nylon, cotton, and polyester materials, and an asbestos flame retardant layer 103 is fixedly embedded on the extended braided layer 102, and the outer surface of the asbestos flame retardant layer 103 is fixedly embedded with a heat-resistant layer 104, and the heat-resistant layer 104 is composed of an inner and outer composite structure of a cross-linked polyethylene layer and a low-smoke halogen-free flame retardant polyolefin layer, and a wear-resistant layer 105 is fixedly composited on the heat-resistant layer 104, and the wear-resistant layer 105 is made of toughened aluminum oxide material.

[0032] It should be noted that the provided extended braided layer 102 greatly improves the connection strength of the belt body 1, the provided heat-resistant layer 104 effectively enhances the flame retardancy and high temperature resistance of the belt body 1, and the asbestos flame retardant layer 103 further enhances the flame retardancy of the belt body 1, and the wear-resistant layer 105 greatly improves the wear resistance of the belt body 1.

[0033] The working principle of the highly flame-retardant fire-proof fire hose provided by the utility model is as follows:

[0034] The extended braided layer 102 provided on the belt body 1 greatly improves the connection strength of the belt body 1. The heat-resistant layer 104 effectively enhances the flame retardancy and high temperature resistance of the belt body 1. The asbestos flame retardant layer 103 further enhances the flame retardancy of the belt body 1. The wear-resistant layer 105 greatly improves the wear resistance of the belt body 1.

[0035] When using the belt body 1 to extinguish a fire, the connecting pipe head 7 adjacent to the one-way water inlet valve 5 on the belt body 1 is connected to the fire hydrant connection end, and the connecting pipe head 7 adjacent to the one-way drain valve 6 on the belt body 1 is connected to the fire extinguishing spray gun, so that water can enter the elastic bottom bag 2 through the one-way water inlet valve 5 and flow back to the other side of the belt body 1 through the one-way drain valve 6 on the elastic bottom bag 2;

[0036] When the water enters the belt body 1, part of the water enters the elastic bottom bag 2 through the one-way water inlet valve 5, so that the elastic telescopic pleated sections 21 on both sides of the elastic bottom bag 2 are extended and the elastic bottom bag 2 is expanded. Since the expanded elastic bottom bag 2 is an elastic structure, the elastic bottom bag 2 improves the pressure bearing capacity of the belt body 1 on the one hand, and reduces the wear on the bottom of the belt body 1 on the other hand. The plastic ball 3 arranged at the bottom of the flame-retardant polyester braided layer 22 greatly reduces the friction between the belt body 1 and the ground, which not only makes it easier for firefighters to drag the belt body 1 towards the flame, but also further reduces the wear between the belt body 1 and the ground.

[0037] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0038] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
