Provide fire extinguishing hose that is attached to the machine and does not miss the digestion timing.
SOLUTION: A flexible tubular body 1 and a cushion layer 2 on a wall of the tubular body are included, and luminous indicator lines 140, 146 are provided in an axial direction on an outer surface of the flexible tubular body, and a plurality of cushion lines are formed on the surface of the cushion layer. The flow path 21 is provided, and these flow paths project or dent from the cushion layer surface, and these flow paths are installed in parallel to the axial direction of the flexible tube. When the high-pressure water stream flows in the pipe by the crest, it is guided to the pipe outlet along the axial direction.

Description

  The present invention relates to a kind of fire hose, and more particularly, to a fire hose that can be used for transportation of a high-pressure water flow and can clearly indicate a position in a dark place.

  In general, fire prevention equipment such as fire alarms, smoke sensors, fire automatic sprinklers, etc. are installed in buildings, and these fire fighting equipments are used to extinguish fire and achieve the purpose of protecting safety in the event of a fire emergency. Yes. However, these fire-fighting facilities are usually placed in inconspicuous places of buildings, such as stair landings, entrances or corners of the lobby, which can attract people's attention when it is bright, In an emergency situation where a fire panic occurs, the room is dark, smoke is trapped in the environment, and high heat is filled, it is not possible to know where the fire fighting equipment is located, and it is impossible to extinguish the fire. For this reason, the timing of effective fire suppression is lost, and not only do we lose the household property due to the intense fire, but the safety of people's lives is threatened. For this reason, it is an important key for the application of fire fighting equipment to make it possible to clearly identify fire fighting equipment in the event of a power outage.

  In general, most water for firefighting is used as a source of high-pressure and high-speed water. When such high-pressure and high-speed water flows through a fire hose, the impact force of a huge water stream repels the fire hose. It becomes difficult to control the fire, the fire extinguishing efficiency is deteriorated, and further, the person may be injured by the disturbed movement of the hose. Therefore, it is desirable to be able to prevent the turbulent movement of the fire hose during water feeding.

  The purpose of the present invention is to provide a kind of fire hose, which installs a plurality of flow conduits inside the hose tube, guides the high-pressure water flow inside the tube, reduces the impact force, and extinguishes the fire. This prevents the turbulent movement of the hose during water supply and solves the drawbacks that make it difficult to control the fountain direction.

  The present invention also aims to provide a kind of fire hose, which is equipped with a nocturnal marking line on the surface of the hose, which can clearly indicate the position of fire fighting equipment at night and in confused fire sites, so that the user can instantly Can be used to extinguish fire and enhance the fire fighting effect.

  According to the present invention, a fire hose includes a flexible tube and a cushion layer provided on the wall of the tube.

  The outer surface of the flexible tube is provided with one or more nightlight marking lines in the axial direction, and these nightlight marking lines are exactly above when the flexible tube is compressed and flattened. It is located at the lower ridge line portion, and most preferably, the above-mentioned nocturnal marking line is formed by integrally knitting the fibers of the phosphorescent material directly on the tube body.

  These cushion layers are provided on the wall surface of the tubular body, and a plurality of flow guiding paths are provided on the surface of the cushion layer, and these flow guiding paths protrude or dent about 0.5 mm to 2 mm from the cushion layer surface. . Most preferably, these flow paths are installed in parallel along the axial direction of the flexible tube.

  With the above-described installation, when the high-pressure water flow flows in the pipe by the flow guide path on the cushion layer, it is guided to the pipe outlet along the axial direction, so that the hose does not move turbulently when water is supplied, And it is easy to control the direction of the fountain. In addition, the luminous sign line of the flexible tube releases the fluorescence and can be used or attached promptly, so that the fire fighting timing is not missed.

  In the fire hose of the present invention, the flexible tube 1 and the cushion layer 2 are configured together. As shown in FIG. 1, normally, a quick female connector 12 and a quick male connector 13 are pivotally connected to two ends of the flexible tube 1, and the quick female connector 12 (or the quick male connector 13) is another one. Two quick male connectors 13 (or quick female connectors 12) of the same structure can be pivoted, thereby extending the length of the fire hose indefinitely.

  The flexible tubular body 1 is made of a material such as plain woven or twilled linen or synthetic fiber cloth, and has characteristics such as high strength, abrasion resistance, fire resistance and high temperature resistance. It can be compressed into a flat band shape and wound into a cylindrical shape for storage. As shown in FIGS. 1 and 2, the outer surface of the flexible tube 1 is provided with two luminous indicator lines 14a and 14b along the axial direction, and the luminous indicator lines 14a and 14b are exactly the same. When the flexible tube 1 is flatly compressed and positioned on the upper and lower ridge lines, and is wound and stored in a cylindrical shape, the luminous indication lines 14a and 14b are formed on the upper and lower end surfaces of the reel. Appears (FIG. 3). Moreover, the above-mentioned nocturnal marking line most preferably solves the fault that the phosphor of the phosphorescent material is directly mixed to form a tubular body, whereby the known nocturnal marking line is easily dropped. The aforementioned phosphorescent material is a sulfide or rare earth compound of Zns: Cu (green light emission), ZnCds: Cu (yellow light emission), and has a high luminance and a long light emission time. The nocturnal marking line can emit bright fluorescence for a long time in the dark, and achieves the purpose of marking the target article position. As a result, the fire hose can be clearly marked and used even in the dark or in a confused disaster environment.

  As shown in FIG. 2, the cushion layer 2 is bonded to and covers the inner wall surface of the flexible tube 1, and a plurality of flow guiding paths 21 are provided on the surface of the cushion layer 2. The flow guiding paths 21 are installed in parallel along the axial direction of the tubular body, and these flow guiding paths protrude from the surface of the cushion layer 2 by about 0.5 to 2 mm or are recessed. The high pressure water flow in the pipe is directed forward by the flow guiding path 21 on the cushion layer 2 to relieve the impact force, and the disadvantage that the fire hose is disturbed at the time of water supply and the fountain direction is difficult to control is prevented. Is done.

  The present invention is not limited to the above-described form, and many improvements and modifications can be made with reference to the above description. For example, the effect of guiding the high-pressure water flow in the pipe in the forward direction can be achieved even when the protruding guiding path 21 on the cushion layer of the above-described embodiment is a guiding path that is recessed from the cushion layer surface.

It is a three-dimensional view of the present invention. It is a pipe body sectional view of the present invention. It is the external appearance three-dimensional view wound by the cylinder shape of this invention.
