Immediately after the evacuation is released, it is necessary to completely drain the human waste, wash it with water, thoroughly disinfect it, and use it again. The rainwater storage tank and the toilet tank may be formed of concrete other than steel, and the inner surface may be finished with waterproof mortar. Concrete is strongly alkaline and the water stored inside does not rot. If the alkalinity is lowered and the water purifier is used, the rainwater becomes emergency drinking water. This example is
The underground warehouse is described as a toilet tank 40 and a rainwater storage tank 50,
It may be a toilet tank and a warehouse. Initially, emergency equipment is stored as a warehouse, and emergency equipment is taken out of the warehouse and switched to a toilet tank in an emergency. Further, the underground warehouse may be used as a toilet tank from the beginning. In this case, the capacity of the toilet tank is twice as large as that of the embodiment. Furthermore, if the underground warehouse is deep, it may be divided into upper and lower parts with a floor material interposed, and the lower layer may be a place for installing a toilet tank and the upper layer may be a place for installing a toilet.

Next, the operation of the present invention will be described for each embodiment. First, the independent power supply system of the first embodiment will be described. The electric power obtained by converting the sunlight into electric energy by the solar cell 3 is sent to the charge controller 5 via the charging cable 18, and is controlled by the charge controller 5 to distribute the electric power evenly to a small capacity and to distribute the electric power to each battery 6. And is accumulated so as to be uniform.
When the power capacity of the battery 6 is small, the charge controller 5 charges and accumulates the power from the solar cell 3 regardless of the capacity. When the battery 6 is fully charged, the power from the solar cell 3 is automatically stopped to prevent overcharging. Then, the battery 6 is in a state of being filled with electric power and supplied at any time. If there is a need to supply electric power from the output part B of the inverter 7 to external electric equipment and power tools, plug the electric equipment and power tools into the outlet and turn on the switch P. Automatically operates to stably supply a required amount of power from the inverter 6. When the capacity of the battery 6 is not full, the charge controller 5 controls the battery 6 to output uniformly and supply power stably. Also charge controller 5
Controls the electric devices and the electric tools in a stable state by controlling not to overdischarge to the output units A and B. The interior light 8 is connected from the output section A of the inverter 7 via the wiring 19 and can be turned on and off by the switch P. Therefore, regardless of the size of the capacity from the solar cell 3, the output power is always stored in the battery and stored with the stored power of the battery larger than the output power of the solar cell. At least 2-3 days can be secured. In addition, as a practical example of this power supply system, a total of three units, a high-speed cutter of 15 A and two submersible pumps of 400 W, can be used at the same time.

Next, an independent power supply system according to a second embodiment will be described. Parts common to the first embodiment are omitted. The air in the underground warehouse 2 is discharged from the air vent hole 17 above, and outside air enters, and the air in the warehouse 2 is circulated. Warehouse 2
Since, except for the connecting portion 27, is buried under the ground, it is not affected by the temperature of the ground surface and maintains a constant temperature, so that the food can be stored for a long time without changing its taste. In the house 1, foodstuffs and the like are stored underground, and the power supply device 4 is arranged under the floor, so that the floor is flat and the entire floor can be used as a living space for evacuees to sleep. Even at night, the stored electric power is supplied from the output units A and B of the inverter 7 and the illumination lamps (electric lamps) are turned on, so that the fear of the infant at night can be eliminated. In addition, if a television, a radio, or the like is used, the disaster situation can be grasped by news. Furthermore, since well water can be pumped up and used via a pump, it is possible to secure water when electric power, pools and wells are installed outside the disaster prevention house. In addition, an underground warehouse integrated with the house is provided under the house for disaster prevention, the lid provided on the floor is opened, and foods and the like can be taken out through a ladder.

In the third embodiment, the power supply device 4 is disposed in the step portion 30 below the ladder 16, so that the floor material 1 of the house 1 is provided.
No. 0 does not require a concave portion, and the space between the upper part of the underground warehouse 2 and the floor can be reduced, so that the upper surface and the upper part of the side surface of the underground warehouse 2 can be exposed from underground.

In the fourth embodiment, since the disaster prevention house is provided with a common toilet for refugees, not only the power supply but also the worry of defecation is solved. The toilets are not flush type but pump type, but are available to many people in case of emergency.

[0040]

Since the present invention is configured as described above, the following effects can be obtained.

Since the power supply system is an independent power supply, even if the power supply from the power company is cut off due to a disaster such as an earthquake, fire, or tsunami, the minimum power required for daily life is normally used in the disaster prevention house used as an evacuation destination. Can be used with confidence. If there are pools and wells around the house as a water source, the landing pump can be driven by electricity to draw water and secure drinking water.

At night, the stored electric power is supplied from the output section of the inverter, and the lighting equipment is turned on. It is also convenient for lighting the passage of defecation in the middle of the night, such as for the elderly.

The output part of the inverter of the power supply unit is an outlet or a plug, and is easily connected to general electric appliances and electric tools.
