Description

  The present invention relates to a disaster prevention warehouse, and more particularly, to a disaster prevention warehouse having a configuration capable of storing relief supplies for a long period of time including foods and pharmaceuticals that are easily altered by the influence of ambient temperature.

There are various types of warehouses for storing relief supplies that are needed in the event of an earthquake or other disaster, such as assembly-type and fixed-type storage, and in either form, the supplies necessary for relief are stored in the internal storage space. The structure is provided (for example, patent document 1).
On the other hand, as a function of the disaster prevention warehouse, there is a case where it is necessary to secure electric power which is one of the lifelines, and as a configuration for this purpose, a configuration capable of supplying electric power with a private power generation function and a storage battery has been proposed. (For example, Patent Documents 2 and 3).

JP-A-11-350760 (paragraph "0002" column) JP 11-71939 A (paragraph "0008" column) JP 2000-17881 A (paragraph “0020” column)

However, some of the preserved goods include foods and medicines that change in quality due to the influence of ambient temperature. These goods are stored in the warehouse together with other relief supplies such as evacuation equipment. It is difficult. Therefore, although it is disclosed in Patent Document 1 that a structure that allows ventilation in the warehouse or a wall panel is formed of a heat insulating material, such a special structure causes an increase in cost, and public facilities However, it may be expensive to prepare for ordinary civilians.
In terms of securing the power source, liquid fuel for generators may be required for in-house power generation, which may increase maintenance costs and store liquid fuel for a long period of time. Then, it may deteriorate and it may become difficult to restart the generator engine.
Therefore, the use of natural energy such as sunlight has also been proposed in the above patent document, but the electromotive function is low only with natural energy, and when electric power generated with natural energy is used, it takes a long time to recharge. May not be reused immediately. In this way, all are premised on the use of in-house power generation and are not designed to use relatively low commercial power in terms of cost, so maintenance other than during disasters, when it is time to take out goods from the warehouse This results in increased costs. Moreover, in order to store materials that are difficult to store for a long time due to temperature, it may be possible to install a freezer or cold storage that is not easily affected by temperature separately from the warehouse and operate these devices for a long time using a commercial power supply. However, if a power failure occurs before the disaster occurs, the stored materials may deteriorate in quality.

In view of the problems in the conventional disaster prevention warehouse, the object of the present invention is to prevent the deterioration of the quality of materials that are difficult to store for a long time, as well as materials that are difficult to store for a long time due to the influence of temperature. It is to provide a disaster prevention warehouse with a possible configuration.
Furthermore, the objective of this invention is providing the disaster prevention warehouse provided with the structure which can suppress the maintenance cost rise except at the time of a disaster.

  The invention according to claim 1 is equipped with a power consuming device including at least a cold storage in the storage space in a disaster prevention warehouse having a storage space for relief goods by a wall member capable of shielding the inside from the outside, and the power consumption The power supply of equipment can be switched between commercial power supply and emergency power supply. Normally, the power supply to the above power consuming equipment is provided by the commercial power supply, and at least a generator with a gas engine is provided in the event of a power failure such as a disaster. It is characterized by using an emergency power supply.

  According to a second aspect of the present invention, in the disaster prevention warehouse according to the first aspect, in the event of a power failure such as a disaster, the power of the power consuming device is covered by an emergency power source comprising a generator with a gas engine and a generator using natural energy. It is characterized by that.

  According to a third aspect of the present invention, in the disaster prevention warehouse according to the first or second aspect, the power switching unit for the commercial power source and the emergency power source includes at least an emergency power consuming device such as a cooker, a communication device, and an emergency device. An output terminal capable of outputting electric power is provided.

  According to a fourth aspect of the present invention, in the disaster prevention warehouse according to any one of the first to third aspects, the commercial power supply and the emergency power supply are connected to a configuration capable of displaying a power usage status. It is said.

  According to the first aspect of the present invention, a power supply device including at least a cold storage is provided in the storage space for relief goods, and a commercial power source and an emergency power source are used as power sources for the cold storage as one of the power consumption devices. In order to prevent deterioration of the quality of stored materials in the refrigerator even during a power failure This makes it possible to store materials whose quality deteriorates due to temperature. Moreover, since the cold storage can be stored in the storage warehouse, it is possible to prevent breakage of the cold storage without being exposed to wind and rain without requiring preparation of an extra installation location. In addition, since at least a generator with a gas engine is used as an emergency power source, the deterioration of fuel is much less than that with a generator with an engine using liquid fuel, and it is possible to prepare for a disaster that cannot be understood when it occurs.

  According to the invention of claim 2, since the generator with a gas engine and the generator using natural energy are used as the emergency power source, the power supply time after switching from the commercial power source to the emergency power source can be extended, In addition, even if one of the above generators breaks down, power can be supplied, preventing deterioration of the quality of power consuming equipment, especially materials in the refrigerator that cannot be stored when the cold storage state stops. And long-term storage becomes possible.

  According to the third aspect of the present invention, the power switching unit for the commercial power supply and the emergency power supply is provided with power to the emergency power consuming equipment such as a cooking device and a communication device used in an emergency such as a disaster, and an emergency equipment. Since the output terminal is provided, it is possible not only to save materials prepared in the event of a disaster, but also to secure a power source for equipment that is required in the event of a disaster.

  According to the fourth aspect of the present invention, since the output part of the commercial power supply and the emergency power supply is provided with a configuration for displaying the power usage status, the type of the switched power supply or the remaining power consumption is identified. Therefore, it is possible to predict and cope with the power supply stoppage time by determining in advance whether the stockpile materials are stored or not and the state of power shortage.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the illustrated embodiments.

  1 and 2 are schematic views showing the inside and outside of a disaster prevention warehouse according to an embodiment of the present invention.

The storage space, which is composed of the internal space of the disaster prevention warehouse 1, is equipped with equipment shelves 3 for evacuation equipment and equipment necessary for relief, as well as relief that causes deterioration in quality due to the temperature of food, medicine, etc. A cold storage 4 for storing supplies is provided.
The cold storage 4 that is one of the power consuming devices is configured such that the internal space is maintained at a constant storage temperature by the freezer refrigeration machine 5, and other power consuming devices include a ventilation fan that ventilates the storage space. 6 or an electric lamp 7 (see FIG. 2) provided on the top of the door 2 is used. In addition to the electric lamp located at the upper part of the door 2, although not shown, lighting tools in the storage space are also prepared.

  In this embodiment, a commercial power source and an emergency power source are used as the power source for the power consuming device. As shown in FIG. 1, at least the generator 8 with the gas engine is provided outside the wall of the disaster prevention warehouse 1 as the emergency power source. Installed. Further, as an emergency power source, not only the above-described generator with a gas engine, but also a solar battery 9A and a wind power generator 9B, which are generators using natural energy, are provided on the ceiling surface of the disaster prevention warehouse 1 as shown in FIG. It has come to be used together.

FIG. 3 is a block diagram for explaining a power supply system using an emergency power source. In FIG. 3, a power source switching device 10 corresponding to a power source switching unit includes a commercial power source 11 and a gas engine on the input side. A controller 12 is provided which is connected to the generator 8 and can switch the power supply path. Further, a solar battery 9A and a wind power generator 9B, which are generators using natural energy other than the generator with a gas engine, are connected to the input side of the power supply switching device 10, respectively.
The controller 12 has a storage battery 13, a power consuming device 16, and an outlet 14 used as an output terminal for power to an emergency power consuming device such as a cooker or communication device used in an emergency such as a disaster, or an emergency device. Each is connected.

The controller 12 shown in FIG. 3 is a relay capable of switching a power supply path from a power source including a commercial power source 11, a generator 8 with a gas engine constituting an emergency power source, a solar battery 9A, a wind power generator 9B, and a storage battery 13. R, a DC converter CB, and an inverter IB are included. Normally, the power for storing electricity in the storage battery 13 is obtained by combining either the commercial power supply 11 and the solar battery 9A, or the wind power generator 9B, or a combination thereof. The obtained electric power is DC converted as necessary and stored.
Normally, the power of the commercial power supply 11 is directly supplied to the power consuming device 16 in the disaster prevention warehouse 1, and the power supply path is automatically switched by the relay R in the event of a power failure such as a disaster, and the power from the storage battery 13 is supplied. It is possible to supply power to the power consuming device 16 after AC conversion. The generator with the gas engine is started in response to switching of the power supply path to the storage battery 13 side.
Further, the controller 12 determines the amount of electricity stored in the storage battery 13, and when the amount of electricity stored reaches a predetermined amount, the controller 12 can directly supply power to the power consuming device 16 from the emergency power source even during normal times. It is possible to prevent damage to the storage battery due to overcharge and excessive consumption of the storage battery due to overdischarge.

In FIG. 4 and subsequent figures, the term “attached device” corresponds to the ventilation fan 6 and the electric lamp 7 described in FIGS.

In the controller 12, when the power supply from the commercial power supply 11 is stopped, for example, when a power failure occurs, the controller 12 is automatically switched to a power supply path that can supply power from the emergency power supply.
FIG. 5 shows this case. In this case, the power supply path is automatically switched by the relay R in the controller 12. In FIG. 5, “x” in the power supply path indicates a path in which power supply is not possible due to disconnection or power failure.
FIG. 6 shows another example in the normal time, which corresponds to a case where the power consumption of the accessory device is low, and power is always supplied from the emergency power source to the accessory device. In this example, the generator 8 with a gas engine is stopped normally, and the generator 8 with a gas engine is started at the same time when the power supply path is switched.

Next, another embodiment of the present invention will be described.
FIG. 7 is a block diagram showing the configuration of the main part of the power supply switching device 10. In the same figure, the output unit of the controller 12 includes the cool box 4 and the attached device 6 in the same manner as shown in FIGS. , 7 and a power usage status display unit 15 in addition to the outlet 14 as an output terminal to the emergency power consuming device.

In this embodiment, as shown in FIG. 2, a patrol light (for convenience, attached to the column of the wind power generator 9B). In FIG. 2, the light 15 is turned on, blinked, and turned off so that the commercial power supply operation, emergency power supply operation, and power supply stop states can be displayed. .
Furthermore, in addition to changes in the lighting state due to patrol lights, when an emergency power supply is used using a monitor screen (not shown), it is obtained from the remaining usage, that is, the output voltage of the storage battery and the current power consumption. It may be possible to display the remaining usable time.
In this configuration, it is possible to determine which of the commercial power supply 11 and the emergency power supply is being used, and in the case of an emergency power supply, it is possible to identify the time during which power can be supplied based on the power consumption with respect to the amount of power The power supply stop time can be predicted. As a result, the storage status of relief supplies can be managed in the event of an unexpected power outage other than during a disaster, and the time during which an emergency power supply can be supplied can be identified even during a power outage during a disaster, and information for relief can be conveyed. .
In addition, instead of the controller 12 having the relay R, for example, in the case of an earthquake disaster, a configuration that operates according to the seismic intensity of the earthquake may be used, or combined with a seismometer. It is also possible.

FIG. 8 is a diagram showing a configuration of a gas engine 8A for driving a generator 8 with a gas engine used as one of emergency power sources.
The gas engine 8A shown in the figure uses a low hydrocarbon such as propane gas or butane gas as a main component and has good storability as fuel, and is stored under pressure in the gas cylinder 8A1. In this embodiment, liquefied butane gas is used. The fuel is not limited to liquefaction, and vaporized fuel such as natural gas (CNG) that can be stored can also be used.
When a power failure occurs during a disaster, a valve (not shown) in the middle between the gas engine 8A and the connecting pipe 8A2 of the gas cylinder 8A1 is automatically opened to supply fuel to the gas engine 8A. At the same time, the gas engine 8A is started by a cell motor (not shown) with electric power from the storage battery 13.
The fuel supplied from the gas cylinder 8A1 is filtered by the regulator 8A3 and supplied to the vaporizer 8A4. Lubricating oil is also supplied to the carburetor 8A4, and a mixture of fuel, lubricating oil, and air is ignited by the plug 8A6 inside the cylinder 8A5, and the power shaft is driven through a piston (not shown). A generator body 8B is attached to the power shaft, and obtains power during a power failure.
If fuel can be supplied from the gas cylinder 8A1 to the gas cooker separately from the gas engine 8A, it is possible to prepare for securing a heat source that may be urgently needed in the event of a disaster.
