Description

Technical Field

[0001] This utility model relates to the field of fire hose technology, specifically a high-strength wear-resistant composite fire hose. Background Technology

[0002] Fire hoses are flexible pipes specifically designed for firefighting, used to transport high-pressure water or extinguishing agents such as foam. They are a crucial component of firefighting systems, connecting fire pumps (or fire hydrants) to fire nozzles (or other spraying devices) to rapidly and efficiently deliver extinguishing agents to the fire scene.

[0003] In the prior art, Chinese patent application number CN202120783450.8 discloses a high-pressure resistant fire hose, including a fire hose body, a hose connector fixedly connected to a hose connector head by a connecting clamp, an annular groove on the hose connector head, the connecting clamp engaging inside the annular groove, rubber sealing rings fixedly installed on the left and right sides of the annular groove, an upper clamp and a lower clamp connected by a fastening device, multiple protrusions fixedly installed on the upper clamp and the lower clamp on the side corresponding to the hose connector head, an inner lining layer inside the fire hose body, a fireproof layer outside the inner lining layer, a braided layer outside the fireproof layer, a pressure-resistant layer outside the braided layer, and a protective layer outside the pressure-resistant layer.

[0004] Based on the above information, it can be seen that existing fire hoses are generally made of multi-layered composite materials (such as fireproof layers, pressure-resistant layers, etc.). However, in actual use, firefighters need to move to extinguish fires, which causes severe friction between the fire hose and the ground. Ordinary fire hoses have poor wear resistance, which shortens their overall service life. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength, wear-resistant composite fire hose to solve the problem of poor wear resistance mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength wear-resistant composite fire hose, comprising a hose body, with connectors with buckle structures fixedly installed at both ends of the hose body; longitudinal reinforcing strips and transverse reinforcing strips fixedly arranged on the inner wall of the hose body, and the longitudinal reinforcing strips and transverse reinforcing strips forming a mesh structure; and a wear-resistant pad fixedly arranged on the outer surface of the hose body, and the wear-resistant pad is made of soft rubber.

[0007] Preferably, both the longitudinal reinforcing strips and the transverse reinforcing strips are made of composite polyester fiber, and the longitudinal reinforcing strips and the transverse reinforcing strips are woven into an integral structure with the main body of the hose.

[0008] Preferably, the wear-resistant pad has weight-reducing grooves distributed at equal intervals inside.

[0009] Preferably, the outer surfaces of the front and rear ends of the hose body are fixedly installed with Velcro fasteners, and the Velcro fasteners are adhesively connected to the outer surfaces of the hose body.

[0010] Preferably, anti-slip blocks with equal spacing are fixedly installed on the outer surfaces of the front and rear ends of the water hose body.

[0011] Preferably, the main body of the water hose comprises four parts: an impermeable layer, a braided layer, a filling layer, and an anti-corrosion layer, and the impermeable layer, braided layer, filling layer, and anti-corrosion layer are sequentially pressed and bonded together.

[0012] Preferably, the impermeable layer is made of polyethylene film, the woven layer is made of nylon fiber, the filling layer is made of flame-retardant acrylic fabric, and the anti-corrosion layer is made of polytetrafluoroethylene composite fabric.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-strength wear-resistant composite fire hose adopts a novel structural design, the specific details of which are as follows:

[0014] 1. Wear-resistant pads are fixedly installed on the outer surface of the water hose body. The wear-resistant pads are made of soft rubber material. Rubber material has good wear resistance. When it rubs against the ground during use, the wear-resistant pads are rubbed first, thereby achieving the purpose of protecting the water hose body and extending the overall service life. In addition, weight-reducing grooves are opened inside the wear-resistant pads to prevent the added wear-resistant pads from significantly increasing the overall weight of the water hose body.

[0015] Furthermore, an integrated longitudinal reinforcing strip and a transverse reinforcing strip are fixedly installed on the inner side of the water hose body. The longitudinal and transverse reinforcing strips provide a certain tensile force to the water hose body, thereby improving the overall high pressure resistance of the water hose body.

[0016] Furthermore, the front and rear ends of the hose body are equipped with fastening Velcro and anti-slip blocks. The fastening Velcro is used to attach and secure the front and rear ends after the hose body is rolled up, preventing it from becoming loose. The anti-slip blocks provide friction for the hands during use, reducing the risk of slipping out.

[0017] 2. The main body of the water hose is divided into four parts: an impermeable layer, a braided layer, a filling layer, and an anti-corrosion layer. The impermeable layer prevents internal water from seeping out during use. The flame-retardant material in the filling layer achieves the purpose of flame retardancy. The anti-corrosion layer prevents the water hose from being corroded and damaged by long-term contact with water and air. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1 , Figures 3-4 In order to improve the wear resistance and strength of the hose, this embodiment provides the following technical solution, which specifically discloses: a hose body 1, with connectors 2 with buckle structures fixedly installed at both ends of the hose body 1, longitudinal reinforcing strips 3 and transverse reinforcing strips 4 fixedly arranged on the inner wall of the hose body 1, and the longitudinal reinforcing strips 3 and transverse reinforcing strips 4 forming a grid structure, both the longitudinal reinforcing strips 3 and transverse reinforcing strips 4 being made of composite polyester fiber, and the longitudinal reinforcing strips 3 and transverse reinforcing strips 4 being woven into the hose body 1 as an integral structure, and wear-resistant pads 7 being fixedly arranged on the outer surface of the hose body 1, and the wear-resistant pads 7 being made of soft rubber, with weight-reducing grooves 8 evenly distributed inside the wear-resistant pads 7.

[0026] When using the hose, first take out the main body 1 of the hose and lay it out. Then connect one end of the connector 2 to the fire water supply device (fire hydrant or fire truck) and the other end to the nozzle structure. The fire water is delivered to the nozzle through the main body 1 to achieve the purpose of extinguishing the fire. During use, the grid structure formed by the longitudinal reinforcing strips 3 and transverse reinforcing strips 4 inside the main body 1 provides a certain tensile force to the main body 1, thereby improving the overall strength of the main body 1 and allowing the main body 1 to collect better water pressure. When the firefighter operates the main body 1, friction occurs at the point where the main body 1 contacts the ground. At this time, the wear-resistant pad 7 on the outer surface of the main body 1 is rubbed first. The wear-resistant pad 7 protects the main body 1 and extends its overall service life. The wear-resistant pad 7 has a weight-reducing groove 8 inside to prevent the overall weight from being excessive.

[0027] Example 2: Please refer to Figure 2 In order to prevent the water hose from coming loose after winding, this embodiment provides the following technical solution, which specifically discloses that: the outer surfaces of the front and rear ends of the water hose body 1 are fixedly installed with fastening hook and loop fasteners 6, and the fastening hook and loop fasteners 6 are glued to the outer surfaces of the water hose body 1; and the outer surfaces of the front and rear ends of the water hose body 1 are fixedly installed with anti-slip blocks 5 that are evenly distributed at equal intervals.

[0028] When firefighters operate the main body of the hose 1, they hold the nozzle with one hand and the anti-slip block 5 with the other hand. The anti-slip block 5 provides a certain friction to prevent the hose from drying out. After the main body of the hose 1 is used, it is rolled up as a whole. After the hose is rolled up, the fastening Velcro 6 at both ends of the main body of the hose 1 is used to attach it to the outer surface of the main body of the hose 1 to achieve the purpose of fixing it and prevent the main body of the hose 1 from coming loose after being rolled up.

[0029] Example 3: Please refer to Figure 5 In order to achieve the purpose of corrosion prevention and flame retardancy, this embodiment provides the following technical solution, which specifically discloses that: the main body 1 of the water hose includes four parts: a seepage-proof layer 101, a braided layer 102, a filling layer 103 and an anti-corrosion layer 104, and the seepage-proof layer 101, the braided layer 102, the filling layer 103 and the anti-corrosion layer 104 are pressed and bonded in sequence. The seepage-proof layer 101 is made of polyethylene film, the braided layer 102 is made of nylon fiber, the filling layer 103 is made of flame-retardant acrylic fabric, and the anti-corrosion layer 104 is made of polytetrafluoroethylene composite fabric.
