FIG. 1 is a schematic view showing a part of a fire fighting hose for disaster countermeasures according to an embodiment of the present invention. 2 is a schematic perspective view of an end of the hose body shown in FIG. FIG. 3 is a perspective view when the joint portion is removed from both ends of the disaster countermeasure fire hose and wound in a roll shape.

Hereinafter, preferred embodiments (examples) of the present invention will be described with reference to the drawings.
FIG. 1 shows a fire fighting hose 2 for disaster countermeasures according to an embodiment of the present invention.

  The belt-like hose body 2a of the fire fighting hose 2 for disaster countermeasures is the same as the conventional one. For example, a synthetic resin is formed on the inner surface of a cylindrical jacket in which a cylindrical fabric is woven with warp and weft by a loom. A lining layer made of, for example, is formed with a lining.

  The structure of the hose body 2a is not limited to this embodiment. That is, although this fire extinguishing hose was described as a “disaster countermeasure fire extinguishing hose”, it is not limited to a so-called fire fighting hose, and can be applied to a simple water supply hose.

  In the disaster countermeasure fire hose 2 of this embodiment, the electric power wire 4 made of a flexible substrate and the flexible substrate are arranged along the inner surface of the pipe line extending in the axial direction of the hose body 2a. The two communication wires 6 and 8 are attached with an adhesive or the like in a state of being spaced apart from each other by a predetermined distance.

  Note that the power wire 4 and the communication wires 6 and 8 made of such a flexible substrate have sufficient water resistance. Further, the number of communication wires 6 and 8 is not limited to two, and may be one.

  Furthermore, in the central region excluding both ends of the hose body 2a, the power wire 4 and the communication wires 6 and 8 are attached to the inner peripheral surface in a state of being spaced apart from each other by a predetermined distance. Further, in both end regions of the hose body 2a to which the metal joint portions A and B are attached, the power wire 4 and the two communication wires 6 and 8 are separated from the inner surface of the hose body 2a and are piped. It extends around the axial core side of the road, and is further gathered into a state where it is gathered into one connecting hardware 10. Note that a male or female socket (not shown) or the like is attached to the connection hardware 10.

  As described above, the connecting portions 4a, 6a, and 8a extended away from the inner surface of the hose body 2a and extending toward the axial core side of the pipe line take into account the fluid resistance inside the hose body 2a. If so, it may be formed of a metal wire having a small cross-sectional area.

When a plurality of disaster countermeasure fire extinguishing hoses 2 formed in this way are prepared in advance and these multiple disaster countermeasure hoses 2 are extended, the upstream hose located on the water supply side and the fire site side Prior to performing a watertight connection between the extended hose and the downstream hose, the pair of connecting hardware 10 and 10 facing each other at the connecting portion is set to be connected by, for example, socket fitting. For example, between the power wire 4 disposed on the upstream side and the power wire 4 disposed on the downstream side, or the communication wire 6 disposed on the upstream side and the communication wire 6 disposed on the downstream side. Further, the communication wire 8 disposed on the upstream side and the communication wire 8 disposed on the downstream side can be electrically connected to each other.
In addition, it is also possible to set so that these electrical connections can be performed simultaneously with a watertight connection operation.

  Therefore, by extending the hose body 2a for supplying water one by one in this way, the power supply wire 4 and the communication wires 6 and 8 are extended near the site where fire fighting activities are performed. be able to. Note that the outlet for the power supply wire 4 and the outlet for the communication wires 6 and 8 are preferably provided on the outer peripheral surface of the cylindrical structure of the joint portions A and B of the disaster countermeasure hose 2.

  With this setting, for example, even if a wildfire occurs in a remote place where the radio wave environment is poor, a communication function can be provided between the fire site and near the water supply. Moreover, even if the power source is not secured at the site where the fire fighting is performed, the power source can be secured.

  Furthermore, in a fire site such as a forest fire, a forest fire robot may be dispatched to carry the fire hose 2 or other materials. When such a wildfire robot is arranged, the wildfire robot is remotely operated by using another communication wire 8 for communication 6 and 8 provided in the fire hose 2 for disaster countermeasures. It is also possible to do.

On the other hand, if such a disaster countermeasure fire hose 2 is housed as a roll body as shown in FIG. 3 when not in use, the electric power wire 4 and the communication wires 6 and 8 attached therein are provided. Since both are formed from a flexible substrate, the hose body 2a is not bulky. Therefore, it can be easily wound into a roll. Thereby, the roll body of the hose body 2a can be stored compactly.
As mentioned above, although one Example of this invention was described, this invention is not limited to the said Example at all.

  For example, in the above embodiment, the electric power wire 4 made of a flexible substrate and the communication wires 6, 8 made of a flexible substrate are attached to the inner surface 2b of the hose body 2a. These electric wires 4, 6, and 8 can be attached to the outer surface of the hose body 2a in a state of being spaced apart from each other by a predetermined distance. Also in such a case, since the electric power wire 4 and the communication electric wires 6 and 8 are thinly formed by the flexible substrate, the bulk does not become bulky when accommodated as a roll body.

  In the above embodiment, the fire fighting hose for disaster countermeasures for fire fighting activities has been described by taking an example of a forest fire as an example. However, the fire hose for disaster countermeasures according to the present invention is also effective for other disasters. Available to: For example, it can be used as a discharge hose for discharging water at a site where a landslide disaster occurs. It can also be used for water supply in other disaster areas.
