Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for causing a fire hose to emit light, and particularly to a method for causing a fire hose to emit light so that the fire hose can be easily seen when performing fire extinguishing activities at night.
[0002]
[Prior art]
When performing fire extinguishing activities in the event of a fire, it is widely practiced to use a fire hose to discharge water. It was an obstacle.
[0003]
The fire hose on the ground is difficult to see especially at night, and it is not uncommon for firefighters to trip or fire engines to step on the fire hose and stop water supply. It was rare.
[0004]
In addition, when performing a fire fighting operation indoors, a firefighter may be wrapped in smoke and may be dangerous to the body. At that time, the fire hose is an effective display means for indicating an escape route.
[0005]
As a means for making the fire hose easily visible in this way, it has been proposed to apply a phosphorescent paint or a fluorescent paint to the fire hose. One example is the invention described in Japanese Patent Laid-Open No. 2000-140146.
[0006]
[Problems to be solved by the invention]
However, in order for the phosphorescent paint to emit light, it is necessary to store the light by applying light for a considerable period of time, but usually the fire hose is housed in a containment vessel, and light is used to prevent fiber and rubber deterioration due to light. Stored in a non-hit state. Therefore, even if it is pulled out from the storage container, it does not emit light immediately.
[0007]
In addition, there is no time to shine light for a long time in a fire scene that is contested for a long time. In the daytime, the light is stored to some extent by natural light during use. However, especially at night when light needs to be emitted, the light is not stored unless a very strong illumination is applied, and the light is practically hardly emitted.
[0008]
It has also been proposed to apply a reflective paint to a fire hose or attach a reflective tape to the surface so that it can be easily seen by reflecting light. Is to reflect the irradiated light in the direction of irradiation, and has no effect unless the viewer has a strong light source and illuminates the fire hose. Fluorescent paints also fluoresce when irradiated with light, and do not emit light without light irradiation.
[0009]
This invention is made | formed in view of this situation, Comprising: When using a fire hose in a fire spot, it aims at making a fire hose light-emit quickly and reliably as needed.
[0010]
[Means for Solving the Problems]
Thus, the present invention is characterized in that a luminescent solution that chemically emits light by mixing is attached to the surface of the fire hose immediately before use of the fire hose.
[0011]
As a method of attaching the luminescent liquid to the fire hose, the luminescent liquid can be attached to the surface of the fire hose while pulling out the fire hose from the hose storage container.
[0012]
Moreover, a luminescent liquid can also be made to adhere to the surface of a fire hose by spraying the said luminescent liquid on the said fire hose in the state accommodated in the hose storage container.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, a luminescent liquid is attached to the surface of a fire hose. As the fire hose, a commercially available fire hose that has been widely used can be used as it is, and it is not necessary to perform any treatment in advance.
[0014]
The luminescent liquid is a liquid that emits light chemically by mixing two kinds of liquids, and a liquid that emits light mainly by mixing an oxalate and an aqueous hydrogen peroxide solution is widely commercially available.
[0015]
This type of luminescent liquid is filled with a hydrogen peroxide solution in a transparent plastic container, a glass ampule filled with oxalate is placed in the plastic container, and the oxalic acid is broken by breaking the ampule from the outside of the plastic container. A mixture of an ester and an aqueous hydrogen peroxide solution that emits light is widely marketed as an optical signal device or a production tool at an event venue, and it is possible to use the chemicals used for these as they are.
[0016]
Various emission durations are available for the luminescent liquid, but in general fire extinguishing activities are most active in the first hour, after which the fire is generally extinguished, otherwise the building Since it is in a burned-out state, it is sufficient if it can sustain light emission for about 1 hour.
[0017]
Thus, in the present invention, these two-component mixed type luminescent liquid is adhered to the surface of the fire hose. The luminescent liquid may be a mixture of two liquids previously attached to the fire hose, or the two liquids may be separately attached and mixed on the surface of the fire hose to emit light.
[0018]
In addition, as a means for attaching the luminescent liquid to the fire hose, a method of applying by a coating means such as a roller, a method of passing or immersing the fire hose in the luminescent liquid, a method of spraying by a spray, For example, a method of spraying a luminescent solution on a fire hose.
[0019]
Further, it is preferable that the luminescent liquid adheres to the fire hose uniformly throughout the entire length of the fire hose, but this is not necessarily a requirement in the present invention.
[0020]
Only a part of the fire hose in the circumferential direction may be attached linearly in the length direction, and also in the length direction, the continuity in the length direction of the fire hose can be recognized by light emission, You may make it adhere intermittently.
[0021]
Hereinafter, a state in which the present invention is implemented will be described with reference to the drawings. FIG. 1 shows an embodiment of the present invention. In FIG. 1, a fire hose 2 folded flat in a hose storage container 1 is further folded in a zigzag manner. A drawer port 3 is formed in the upper portion of the hose storage container 1, and the fire hose 2 is pulled out from the drawer port 3.
[0022]
Reference numeral 4 denotes a coating device formed outside the drawer port 3 of the hose storage container 1. In the coating device 4, a luminescent liquid 6 is accommodated in a liquid container 5, an application roller 7 is provided on the upper part of the liquid container 5, a part of the application roller 7 is immersed in the luminescent liquid 6, and the upper part emits light. It is exposed from the liquid 6.
[0023]
Thus, the fire hose 2 protruding from the drawer port 3 is in contact with the application roller 7, and when the fire hose 2 is pulled out from the hose storage container 1, the application roller 7 in contact with the fire hose 2 rotates. The luminescent liquid 6 attached to the surface is attached to the lower surface of the fire hose 2.
[0024]
FIG. 2 shows another embodiment of the apparatus for carrying out the present invention, in which a liquid container 5 containing a luminescent liquid 6 is provided on the top of a lid 8 that covers the top of the hose storage container 1. A spray tube 9 is attached to the lower surface of the lid 8. The luminescent liquid 6 in the liquid container 5 is sprayed from the spray tube 9 onto the fire hose 2 in the hose storage container 1.
[0025]
In this state, the luminescent liquid 6 adheres only to the fire hose 2 housed in the upper part of the hose storage container 1, but by spraying a sufficient amount of the luminescent liquid 6, the luminescent liquid 6 becomes the fire hose 2. The luminescent liquid 6 can be attached to at least the folded ear of the lower fire hose 2.
[0026]
[Action]
In the present invention, a luminescent solution that chemically emits light by mixing is attached immediately before use of the fire hose. Therefore, the fire hose to which the luminescent liquid is attached emits light with a sufficient amount of light immediately without storing light and without requiring a light source that reflects light or generates fluorescence.
[0027]
【The invention's effect】
Therefore, according to the present invention, when a fire hose is used at a fire site, the fire hose can be made to emit light quickly and reliably as necessary. Therefore, the presence of fire hoses can be easily seen even during nighttime fire fighting activities, and when firefighters are wrapped in smoke during indoor fire fighting activities, the fire hoses emit a strong light and escape routes. Show.
[0028]
Further, in the present invention, a chemically emitting luminescent liquid is attached to the fire hose, so that it is not necessary to store light in advance to emit light like a phosphorescent paint, and like a fluorescent paint or reflective paint. Since it emits light without a special light source, it is extremely effective for fire fighting activities at night and indoors.
[0029]
Further, according to the present invention, the luminescent liquid can be attached to the fire hose by applying the present invention only when the fire hose needs to emit light, such as at night or indoor fire extinguishing. In addition, it is not necessary to prepare a special fire hose for causing the fire hose to emit light, and the present invention can be implemented as needed while using the fire hose that has been used conventionally.
[0030]
Moreover, the luminescent liquid used in this invention can use the cheap thing which consists of an oxalate ester and hydrogen peroxide aqueous solution widely used as an optical signal tool or a production tool as it is.
[0031]
These luminescent liquids are harmless to the human body and to the fibers and linings that make up fire hoses, and can be easily removed by washing with water after use. Can do.
