Description

Technical Field

[0001] This utility model relates to the technical field of flame-retardant fire hoses with good high-temperature resistance, and in particular to a flame-retardant fire hose with good high-temperature resistance. Background Technology

[0002] Fire hoses are flexible tubes used to transport high-pressure water or flame-retardant liquids such as foam. Traditional fire hoses have a rubber inner lining and an outer layer covered with woven linen. Advanced fire hoses are made of polymer materials such as polyurethane. Both ends of a fire hose have metal connectors, allowing connection to another hose to extend the distance or to nozzles to increase the liquid spray pressure.

[0003] The inventor discovered during daily use of fire hoses that water remains inside the hose after use. This necessitates frequently lifting one end of the hose to expel the water during winding, which slows down the winding process and makes it inconvenient to wind up the used hose, thus causing problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flame-retardant fire hose with good high-temperature resistance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a flame-retardant fire hose with good high-temperature resistance, comprising a hose, with connectors fixedly connected to both ends of the hose, and a compression device provided on the surface of the hose. The compression device includes a rectangular plate disposed on the surface of the hose, a screw rotatably connected to the top of the rectangular plate, and a pressure plate threadedly connected to the surface of the screw.

[0006] The effect achieved by the above components is as follows: under the action of the screw, the pressure plate is pressed against the surface of the rectangular plate, thereby squeezing out the water inside the hose, thus achieving the squeezing effect. When the hose needs to be used, the connectors are connected together, allowing water to enter the hose to extinguish the fire source, thereby achieving the fire-fighting function.

[0007] Preferably, a sliding rod is fixedly connected to the top of the rectangular plate, and a pressure plate is slidably connected to the surface of the sliding rod.

[0008] The effect achieved by the above components is that, under the action of the slide bar, the pressure plate will not rotate with the rotation of the screw.

[0009] Preferably, a triangular plate, which is a rubber plate, is fixedly connected to the side of the pressure plate.

[0010] The effect achieved by the above-mentioned components is that, under the action of the triangular plate, the water inside the water hose can be squeezed out when the hose is wound up, thereby facilitating the squeezing out.

[0011] Preferably, the bottom of the rectangular plate is fixedly connected with casters.

[0012] The effect achieved by the above components is that, under the action of the casters, the rectangular plate can move smoothly, thereby squeezing out the water inside the water hose.

[0013] Preferably, a round strip, which is a rubber strip, is fixedly connected to the top of the rectangular plate and the bottom of the pressure plate.

[0014] The effect achieved by the above components is as follows: under the action of the round bar, the water inside the hose is squeezed out. When the hose is used and needs to be wound up, the hose is placed on the surface of the rectangular plate, and the screw is turned by hand. Under the action of the sliding rod, the pressure plate does not rotate with the screw, causing the pressure plate to move down and squeeze the surface of the hose. Under the action of the round bar, the water inside the hose is squeezed out. When the hose is wound up, the hose is squeezed on the surface of the triangular plate. Under the action of the casters, the rectangular plate can move smoothly, thereby squeezing out the water inside the hose, thus achieving the function of discharge and squeezing.

[0015] Preferably, the surface of the water hose is provided with a fireproof device, which includes a fireproof woven bag disposed on the surface of the water hose, and the fireproof woven bag is made of PC material.

[0016] The effect achieved by the above components is that the fireproof woven bag prevents the water hose from burning, thus achieving the fireproof function. Since the fireproof woven bag is made of PC material, it can also achieve the fireproof function.

[0017] Preferably, the surface of the water hose is provided with an annular groove, and the surface of the fireproof woven bag is provided with a rubber band, which is inserted into the annular groove.

[0018] The effect achieved by the above components is that, under the action of the rubber band and the ring groove, the fireproof woven bag is fixed to the surface of the water hose, thereby achieving the function of fixation.

[0019] Preferably, a film is fixedly connected to the surface of the water hose, and the film is connected to the fireproof woven bag.

[0020] The effect achieved by the above components is as follows: under the action of the film, the fireproof woven bag is fixed to the surface of the water hose. When fireproofing of the water hose is required, the fireproof woven bag is placed on the surface of the water hose. Under the action of the film, the fireproof woven bag is fixed to the surface of the water hose. The rubber band is placed on the surface of the water hose. Under the action of the ring groove, the rubber band is inserted into the inside of the ring groove, thereby fixing the fireproof woven bag to the surface of the water hose, thus achieving the fireproofing effect.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting up a squeezing device, when the water hose is used and needs to be wound up, the water hose is placed on the surface of a rectangular plate. By turning the screw by hand, the pressure plate is prevented from rotating with the screw due to the action of the sliding rod, causing the pressure plate to move down and squeeze the surface of the water hose. Under the action of the round bar, the water inside the water hose is squeezed out. When the water hose is wound up, the water hose is squeezed on the surface of the triangular plate. Under the action of the universal wheel, the rectangular plate can move smoothly, thereby squeezing out the water inside the water hose and achieving the function of discharge. This solves the problem that when winding up a used water hose, it is necessary to frequently lift one end of the water hose to drive out the water inside the hose. Because it is necessary to lift it frequently, the winding speed is reduced, which makes it inconvenient to wind up the used water hose. Attached Figure Description

[0030] Working principle: When the water hose 1 is being wound up, it is placed on the surface of the rectangular plate 21. The screw 22 is turned by hand, and under the action of the sliding rod 24, the pressure plate 23 does not rotate with the screw 22. This causes the pressure plate 23 to move down and press against the surface of the water hose 1. Under the action of the round bar 25, the water inside the water hose 1 is squeezed out. When the water hose 1 is wound up, it is pressed against the surface of the triangular plate 27. Under the action of the caster wheel 26, the rectangular plate 21 can move smoothly, thereby squeezing out the water inside the water hose 1, thus achieving the function of discharge and squeezing.

[0032] Working principle: When fireproofing of water hose 1 is required, fireproof woven bag 31 is placed on the surface of water hose 1. Under the action of film 33, fireproof woven bag 31 is fixed to the surface of water hose 1. Rubber band 34 is placed on the surface of water hose 1. Under the action of ring groove 32, rubber band 34 is inserted into the inside of ring groove 32, thereby fixing fireproof woven bag 31 to the surface of water hose 1, thus achieving the fireproofing effect.
