Description

  The present invention is installed in indoor parking lots, outdoor parking lots, automobile maintenance factories, machine factories, dangerous goods storages, etc., and is equipped with a pressure-accumulation or pressure-type powder fire extinguisher storage container and a radiation hose in a storage box Improvement of mobile powder fire extinguishing equipment in which a person moves to a fire source with a radiation hose when a fire breaks out and extinguishes by extinguishing the powder fire extinguisher in a powder fire extinguisher storage container by accumulating or applying pressure. In particular, it is possible to reduce the weight of the radiation hose without reducing the strength of the radiation hose that radiates the powder fire extinguishing agent by using a static elimination type shape retaining hose that has a function of discharging static electricity to the radiation hose. Mobile powder fire extinguishing equipment that can reduce the frictional resistance of the hose surface during handling of the hose and improve the extensibility, and can eliminate static electricity charged to the radiation hose and static electricity charged to the user. It relates.

  In general, mobile powder fire extinguishing equipment installed in parking lots and maintenance factories, for example, has a storage container for powder storage fire extinguishers, a radiation hose, a radiation nozzle, a discharge valve, etc. When the user opens the discharge valve at the time of occurrence, moves to the fire source with the tip of the radiation hose and the radiation nozzle, and then opens the radiation nozzle, the powder fire extinguisher in the accumulator powder extinguisher storage container accumulates pressure. Is radiated from the radiation nozzle through the radiation hose and can be extinguished (see, for example, Patent Document 1).

  By the way, synthetic rubber hoses have been used as radiation hoses for mobile powder fire extinguishing equipment. In this synthetic rubber hose, a synthetic rubber excellent in fire resistance is used on the inner surface, and a synthetic rubber excellent in weather resistance is used on the outer surface.

  However, when using the synthetic rubber hose for the radiation hose of mobile powder fire extinguishing equipment, it is necessary to make the hose structure a three-layer structure of an outer rubber layer, a reinforcing layer, and an inner rubber layer in order to ensure pressure resistance. In addition, the weight of the hose inevitably tends to be heavy, and there is a problem that the handleability is inferior.

  In addition, when using mobile powder fire extinguishing equipment, the radiation hose is greatly deformed when the powder fire extinguishing agent is pressurized, and the radiation hose is disturbed, causing the radiation hose to protrude from the hose storage part of the containment box. There was a problem.

  Furthermore, the radiation hose using a synthetic rubber hose has a high frictional resistance on the hose surface, so when pulling out the radiation hose from the storage box, a corresponding pulling force is required and the radiation hose can be pulled out. In some cases, the radiating hose was greatly violated, causing kinks and tangles. Further, when storing such a radiation hose after use, it may not be possible to store it in the storage box unless the radiation hose is wound in order. In addition, in a cold region, there is a problem that the radiation hose is hardened and handling and operability are further deteriorated.

JP 2004-194950 A

  The present invention has been made in view of such problems, and its purpose is to use a static elimination type shape retaining hose having a function of discharging static electricity to a radiation hose that radiates a powder fire extinguisher, and to extinguish a powder. The radiation hose can be reduced in weight without reducing the strength of the radiation hose that radiates the agent, and the frictional resistance of the hose surface can be reduced and the extensibility improved when handling the radiation hose. It is an object of the present invention to provide a mobile powder fire extinguishing equipment that can neutralize static electricity charged to a hose and static electricity charged to a user.

In order to achieve the above object, the invention of claim 1 of the present invention is provided with an accumulating or pressurizing powder extinguishing agent storage container, a radiation hose, a radiation nozzle and a discharge valve in a storage box, and a powder extinguishing agent. In the mobile powder fire extinguishing equipment that radiates the powder fire extinguisher in the storage container from the radiation nozzle through the radiation hose by accumulating or applying pressure, the radiation hose has a function of discharging static electricity to the radiation hose. Using a shape retaining hose, the static elimination shape retaining hose includes a jacket formed by weaving a plurality of synthetic fiber yarns and warp yarns made of one or more conductive fiber yarns and weft yarns made of synthetic fiber yarns into a cylindrical shape, consisting an inner synthetic resin lined on the circumferential surface or rubber cylindrical lining layer of the jacket, the one or warps composed of a plurality of conductive yarns in the longitudinal direction of the jacket on the outer peripheral surface of the jacket Along it is characterized in that a structure which appears in a spiral.

  The mobile powder fire extinguishing equipment of the present invention uses a static-retaining shape holding hose instead of a synthetic rubber-based hose for the radiation hose that radiates the fire extinguishing powder agent, so it is lightweight without reducing the strength of the radiation hose. Can be achieved.

  In addition, since the mobile powder fire extinguishing equipment of the present invention uses a static elimination type shape retaining hose whose friction resistance on the hose surface is smaller than that of a synthetic rubber-based hose, the handling of the radiation hose is improved, and the radiation hose is pulled out. The burden on the user can be reduced at the time of storing the radiation hose.

  Furthermore, since the mobile powder fire extinguishing equipment of the present invention uses a static elimination type shape retention hose, it is not said that it is cured like a synthetic rubber hose even when used in a cold region. Sex does not deteriorate.

In addition, since the mobile powder fire extinguishing equipment of the present invention uses a static elimination type shape retaining hose having a function of discharging static electricity in the radiation hose, a powder fire extinguishing agent is generated between the inside of the radiation hose. Therefore, it is possible to eliminate the frictional charge and the charge when the charged user holds the radiation hose, and the user is not uncomfortable.
In particular, the static elimination type shape retaining hose is twisted in the circumferential direction of the jacket in the processing step of the jacket, and the warp made of conductive fiber yarn spirals on the outer peripheral surface of the jacket along the longitudinal direction of the jacket. Because of the configuration that appears, even if only one warp made of conductive fiber is used, a part of the warp made of conductive fiber is reliably grounded to the ground, so that static elimination can be performed reliably.

Thus, since the mobile powder fire extinguishing equipment of the present invention uses a static elimination type radiation hose for the hose that radiates the powder fire extinguisher, it is possible to reduce the weight while having the necessary strength. In addition, since the frictional resistance on the surface of the radiation hose is small, the handleability of the hose is greatly improved.
As a result, the mobile powder fire extinguishing equipment of the present invention can reduce the burden on the user when the radiating hose is pulled out and stored, thereby improving workability and contributing to quick fire fighting activities. A radiation hose that is easy to handle even under conditions can be obtained.

It is a front view of the mobile powder fire extinguishing equipment in a state where the mobile powder fire extinguishing equipment according to the embodiment of the present invention is shown, the door of the storage box is omitted, and the static elimination type shape retaining hose is wound and stored in the storage box. . The static elimination type | mold shape retention hose used for the mobile powder fire extinguishing equipment of this invention is shown, (A) is sectional drawing which abbreviate | omitted a part of static elimination type shape retention hose, (B) is XX line enlarged of (A). It is sectional drawing.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a mobile powder fire extinguisher according to an embodiment of the present invention, and the mobile powder fire extinguisher is housed and installed in a storage box 1 having a door that can be opened and closed on the front side. A pressure-accumulating powder extinguishing agent storage container 2 for storing powder extinguishing agent, an openable / closable release valve 3 attached to the pressure-accumulating powder extinguishing agent storage container 2, and connected to the release valve 3. A static elimination shape retaining hose 4 that is housed in a wound state and serves as a radiation hose through which a powder extinguisher flows, a radiation nozzle 5 with an opening / closing valve provided at the tip of the neutralization shape retention hose 4, and the inside of the storage box 1 The pressure gas container 6 for pressurizing the pressure-accumulating powder extinguishing agent storage container 2, the cleaning gas container 7 stored in the storage box 1, and the cleaning gas in the cleaning gas container 7 are pressure-accumulated. -Type powder extinguishing agent storage container 2 and static elimination type shape retention hose 4 And a cleaning valve 8 or the like flowing in, the accumulated pressure of the dry chemical powder fire extinguishing agent storage vessel 2 the accumulator type, and is configured to emit a radiation nozzle 5 through neutralization formula shape retaining hose 4.

  The static eliminating shape retaining hose 4 serving as the radiation hose includes a jacket 12 formed by weaving synthetic warp yarns 9 and 10 (warp yarn) made of synthetic fiber and conductive fiber and weft yarn 11 (weft yarn) made of synthetic fiber into a cylindrical shape, It is composed of a synthetic resin or rubber cylindrical lining layer 13 lined on the inner peripheral surface of the jacket 12.

That is, as shown in FIG. 2, the jacket 12 uses a plurality of synthetic fiber warps 9 and one conductive fiber warp 10 for the warp, and one synthetic fiber weft 11 for the weft. The warp yarns 9, 10 and the weft yarn 11 are woven into a cylindrical shape. In this embodiment, the jacket 12 has a cylindrical twill structure.
Further, the jacket 12 is intentionally processed by twisting in the circumferential direction of the jacket 12 in the processing step, and one warp 10 made of conductive fibers is placed on the outer peripheral surface of the jacket 12. It is comprised so that it may appear spirally along the longitudinal direction of 12 (refer FIG. 3).

In this embodiment, a polyester warp is used for a plurality of synthetic fiber warps 9 and a polyester weft is used for one synthetic fiber weft 11.
In addition, for one warp 10 made of conductive fiber, warp made of conductive synthetic fiber, carbon fiber, metal-plated fiber, or metal fiber kneaded with a conductive substance is used.

  On the other hand, the lining layer 13 is formed by lining a lining material made of a light and strong polyurethane resin on the inner peripheral surface of the jacket 12 in a cylindrical shape.

  Next, the case where fire extinguishing activity is performed by the mobile powder fire extinguishing equipment using the above-mentioned static elimination type shape retaining hose 4 will be described.

  In the event of a fire, the user first opens the door of the storage box 1 and opens the release valve 3 attached to the pressure-accumulating powder extinguishing agent storage container 2. Then, the fire extinguishing powder in the pressure accumulating powder extinguishing agent storage container 2 passes through the discharge valve 3 by the accumulated pressure and enters the static elimination type shape retaining hose 4 which is a radiation hose.

Next, the user moves the radiant hose from the storage box 1 to the fire source while holding the tip of the radiant hose (static charge-retaining shape hose 4) and the radiant nozzle 5.
At this time, because the radiation hose is not a synthetic rubber-based hose, but uses the static elimination type shape retaining hose 4, the radiation hose is reduced in weight without reducing the strength of the radiation hose, The friction resistance on the surface of the radiation hose is smaller than that of the synthetic rubber hose. As a result, the handleability of the radiation hose is improved, and the burden on the user can be reduced when the radiation hose is pulled out.

  When the user moves to the fire source, the user opens the on-off valve of the radiation nozzle 5. If it does so, a powder fire extinguisher will be radiated | emitted from the radiation nozzle 5 with a stored pressure, and fire extinguishing will be performed.

In this mobile powder fire extinguishing equipment, since the static elimination type shape retaining hose 4 having a function of discharging static electricity is used for the radiation hose, a powder fire extinguisher is generated between the inside of the radiation hose. Friction electrification and electrification when the charged user holds the radiation hose can be eliminated, and the user is not uncomfortable.
In particular, the static elimination type shape retaining hose 4 is twisted in the circumferential direction of the jacket 12 in the processing step of the jacket 12, and the warp yarn 10 made of conductive fibers is placed on the outer circumferential surface of the jacket 12 in the longitudinal direction of the jacket 12. As shown in FIG. 4, even if only one conductive fiber warp 10 is used, a part of the conductive fiber warp 10 is surely grounded to the ground. , The charge removal can be performed reliably.
Further, the warp 10 made of conductive fiber can discharge static electricity into the air even if it is not in contact with the ground.

On the other hand, after the fire extinguishing operation is completed, the user closes the open / close valve of the radiation nozzle 5 and the discharge valve 3 and stores the radiation hose in the storage box 1 in a wound state.
At this time, since the static elimination hose 4 is used for the radiation hose, the radiation hose is reduced in weight and the frictional resistance on the surface of the radiation hose is reduced. It is possible to reduce the burden on the user when storing the radiation hose.

  Thus, since the above-mentioned mobile powder fire extinguishing equipment uses the static elimination type shape retaining hose 4 for the radiation hose that radiates the powder fire extinguishing agent, the weight of the radiation hose having the required strength is reduced. In addition, since the frictional resistance of the surface of the radiation hose is small, the handleability of the hose is improved. As a result, this mobile powder fire extinguishing equipment can reduce the heavy load on the user during fire fighting activities, improve workability, and is useful for quick fire fighting activities. Moreover, by using the static elimination type shape retaining hose 4, a radiation hose that is easy to handle under any weather conditions can be obtained.

  In the above-described embodiment, the jacket 12 of the static elimination type shape retaining hose 4 has a cylindrical twill structure. However, in other embodiments, the jacket 12 has a cylindrical plain weave structure. Also good.

  In the above-described embodiment, one conductive fiber warp 10 is woven into the jacket 12, but in another embodiment, the jacket 12 is made of a plurality of conductive fibers. The warp yarn 10 may be woven. In this case, the warp yarns 10 made of conductive fibers are woven so as to be arranged at equal angles in the circumferential direction of the jacket 12 and twisted in the circumferential direction of the jacket 12 in the processing step of the jacket 12. To process.

  Furthermore, in the above-described embodiment, the jacket 12 is processed by twisting in the circumferential direction of the jacket 12, but in the other embodiments, the jacket 12 is processed. In the 12 processing steps, processing may be performed without adding twist processing. In this case, a single conductive fiber warp 10 may be woven into the jacket 12, but if possible, a plurality of conductive fiber warps 10 may be arranged at equal angles in the circumferential direction of the jacket 12. It is preferable to weave warp yarns 10 made of conductive fibers. Then, any one of the plurality of conductive fiber warps 10 is installed on the ground for extending the radiation hose, so that the discharge can be reliably performed.

  Further, in the above embodiment, one weft 11 made of a synthetic fiber is used as the weft 11 forming the jacket 12, but in the other embodiments, the jacket 12 is formed. Two wefts 11 (hard weft and soft weft) made of synthetic fibers may be used as the weft 11 to be used, and the jacket 12 may have a cylindrical horizontal double twill structure.
