Description

  The present invention relates to disaster support equipment, and more particularly to an electric power supply system that can supply electric power from an external power source (for example, an automobile battery) in the event of a power failure caused by a natural disaster or accident.

  In recent years, many technologies relating to an external power source that supplements commercial power in the event of a power failure due to a natural disaster such as an earthquake or a typhoon have been disclosed. These generate electricity using solar light or wind power and store electric power in a storage battery or the like, and required a large amount of money for initial investment.

  Therefore, a power supply system has been proposed in which a direct current supplied from a power supply terminal of a vehicle is converted into alternating current by an inverter and supplied to a power strip, and power can be supplied from the power strip (see Patent Document 1). . In addition, there is an evacuation guidance column during a power failure in which evacuation guidance information is drawn with a paint containing a phosphorescent material (see Patent Document 2).

  The technique proposed in Patent Document 1 is intended for securing power sources in retail stores and the like, and is effective when the arrangement of a switchboard or the like to which power can be connected is known in advance. In public facilities such as, the distribution of power distribution panels that require power is unspecified, and in the case of a power outage at night, there is a problem that power connection work cannot be performed without an external light (such as a portable light) there were. Further, the technique described in Patent Document 2 has a problem that a sufficient amount of accumulated light cannot be secured only by light emitted from a streetlight.

  In view of the above problems, the present inventors can easily find the position of a power distribution panel or the like that requires power when supplying power from an external power source (such as a car battery) in the event of a power failure such as a disaster. We have come to provide a power supply system that allows easy power connection work without an external light (portable light, etc.).

  For this reason, the power supply system of the present invention is attached to the outer wall of a building or a pole of a streetlight, and includes a cable that is connected to an external power source, a DC / AC converter, a power source switch, and an outlet, A first feature is that a phosphorescent plate is provided on the surface and the inner surface of the housing to facilitate power supply work from an external power source when commercial power is not supplied due to a power failure.

  The second feature is that the external power source is a generator or a battery mounted on a vehicle such as an automobile.

  And the said phosphorescent board is further equipped with the light storage illumination means which uses a commercial power supply, and it is set as the 3rd characteristic to store light by this illumination means.

  The light storage illumination means is preferably a light emitting diode capable of emitting light including ultraviolet light.

  According to the power supply system of the present invention, the power supply system includes a housing that is attached to an outer wall of a building or a streetlight pole, and is connected to an external power source, a DC / AC converter, a power switch, and an outlet. It has an effect that power can be supplied from an external power source when commercial power is not supplied due to a power failure such as a disaster.

  The external power supply has an effect that a generator or a battery mounted on a vehicle such as an automobile can be used.

  Furthermore, since the phosphorescent plate is further equipped with a phosphorescent illumination means that uses a commercial power supply, there is no external light (such as a portable light) due to light emission from the phosphorescent plate even during a sudden power outage at night. In addition, it is possible to easily check the installation location of the housing, and it has an excellent effect that connection work can be performed.
