Description

DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application> The present invention relates to a disaster prevention shelter that can be used as an office during normal times and as a shelter during emergencies.

<Conventional technology> In recent years, evacuation centers, i.e. shelters, have been developed in anticipation of disasters such as nuclear war.
Various types of shelters have been developed, and shelters are being devised and becoming more popular so that they can be used not only during disasters, but also as housing during emergencies.

However, because current shelters are essentially designed to be airtight, they are extremely hot in the summer, making them unsuitable for use as residences unless an air conditioner is installed inside, and even in the winter, due to heavy snowfall, There were some unsatisfactory factors, such as an increase in load and the design as it was, making it uncomfortable to use as a residence.

<Problems to be Solved by the Invention> Therefore, the present invention was made to solve the above-mentioned drawbacks of the conventional shelters.The first purpose is to maintain the functions of the conventional shelters, while also making them suitable for living quarters. The purpose of the present invention is to provide a shelter that can be used as an office, which is cool in the summer at all times, and can sufficiently cope with the load of snowfall in the winter. To provide a shelter that can also be used as an office, in which, in an emergency when radioactivity is generated, the shelter, that is, the capsule body covered with radioactive contamination, ie, the capsule body covered with so-called dead ashes, can be cleaned.

Means for Solving the Problems> The present invention has been made to achieve the above object, and its gist is to provide radiation-resistant and gas-resistant steel capsule bodies in various forms; , an entrance section provided with an airtight protective door that communicates the inside and outside of the capsule body;
Water supply and sewage equipment including valves, piping, and toilets for supplying and draining drinking water inside the capsule body, electrical appliances such as irradiation equipment and outlets, air purification equipment such as filters and ventilation, and a desk. and office equipment such as chairs, and is equipped with a sprinkler on the roof of the shelter that communicates with a water tank via a valve, and the sprinkler can be operated manually or by controlling temperature, pressure, etc. This is a disaster prevention shelter that can also be used as an office and has the valves opened and closed by the sensors.

Therefore, the capsule body and the protective wall constitute one shelter body, and office furniture such as water supply and sewage equipment, electrical appliances, air purification equipment, and office equipment are arranged within this one shelter body. . Here, water supply and sewage equipment is an external water supply system or a water supply tank that is previously supplied from an external water supply system, and this tank supplies drinking water to sinks, etc., and also drains water from sinks or sewage from toilets, etc. Electrical equipment refers to equipment that is configured to discharge water to the outside through a valve, and electrical appliances include generators installed inside the shelter or various electrical appliances that supply electricity from outside the shelter and are connected to outlets, lighting equipment, etc. Also, air purification equipment refers to equipment such as filters for filtering outside contaminated air and ventilation for air supply in emergencies, and office equipment refers to desks, chairs, etc., as well as office sets and other equipment as necessary. Refers to information appliances such as television receivers or radio receivers.

Furthermore, although the fire detector and valve that operate the sprinkler according to the present invention must be placed indoors within the main body of the shelter, water from the sprinkler is connected to a water supply tank inside the shelter. It is also possible to use an external water supply tank, external water supply, reservoir, etc. Of course, the valve must be operated manually in the event of an emergency such as a nuclear explosion, or by a temperature sensor that detects when the temperature inside the shelter body rises above a certain level and sends out a signal. Watering may be started automatically using a pressure sensor that detects the amount of water or a detector such as a Geiger counter that detects radioactivity above a certain amount.

<Embodiment> An embodiment of the present invention will be described based on the accompanying drawings. FIG. 1 is a front view of the office-cum-disaster prevention shelter of the present invention installed on the ground, and FIG. 2 is the same as FIG. 1. FIG. 3 is a longitudinal sectional side view of FIG. 1 bt. In the figure, 1 is approximately 911I with a special hill stone spray coating to prevent condensation on the inner surface and a board or wallpaper pasted if necessary.
The main body of the capsule is made of stainless steel and has a cylindrical shape, and the entire body is airtight, making it possible to shield radiation dust, bacteria, and other toxic gases. In addition, when both ends of the capsule body 1 are used as an office, transparent materials such as glass are installed as lighting windows 9, but in the event of an emergency such as an earthquake or nuclear explosion, steel plates such as iron or stainless steel are installed. This makes it possible to seal it tightly. Furthermore, in the center of the front of the capsule body, a protective door 2 with a thickness of 20 mm, a height of 180 aa, and a width of 80 aa is installed in a structure similar to that of a submarine hatch so that it can be opened and closed for access from the outside. . It should be noted that it is highly productive to manufacture the shelter consisting of the capsule body 1, the lighting window 9, and the protective door 2 in advance in a factory, and transport it on a trailer or the like to the planned installation location and place it on the ground 3. A concrete base 4 with embedded reinforcing bars is installed in a ring shape at predetermined intervals, and the capsule body mounting plate provided below the capsule body is placed on the capsule mounting plate on the base, and the capsule is fixed with bolts and nuts. I am trying to fix the shelter. In front of the shelter, a landing 6 is installed in the middle with reinforced concrete, etc., and a staircase 7 with handrails 7' and 7' on both sides is built on this, and a suspension is provided to the protective door 2. There is. In addition,
19 in FIG. 1 is used when the capsule body 1 is placed on the base 4 using a crane or the like.

This is a hanging bracket for hanging with wire.

In addition, a sprinkler 8 is installed at the upper center of the roof of the capsule body 1, and this sprinkler is connected to a water supply tank located indoors or outdoors or to an outdoor water supply via an indoor valve. The valves disposed within the shelter are opened and closed manually or automatically by sensors such as temperature or pressure when the temperature exceeds a certain level or the pressure exceeds a certain level. By arranging the water supply tank on the floor of the capsule body 1, since water has the ability to shield radioactivity, radioactivity can be shielded at the location where the tank is disposed.

Further, in FIG. 2, reference numeral 11 is a sink for supplying drinking water, and reference numeral 12 is a toilet connected to a sewage pipe for discharging outside the capsule via a valve or the like. Further, 13 is a lighting fixture that is lit by a generator outside or inside the shelter, 14 is a table as office equipment, and 15 is a chair.

Furthermore, a reception set 16 is installed inside the capsule body 1, and together with the chairs, desk, books, etc., constitutes office equipment. Furthermore, 17 is an air purification facility that filters contaminated air supplied from the outside with a filter and takes in air through ventilation in the event of an emergency such as a nuclear explosion or earthquake. Note that 18 is a cooler for use when the temperature inside the capsule body rises during summer or the like. Furthermore, since the radiation dose is inversely proportional to the square of the distance, by installing the capsule body 1 on the base 4, not only can radiation from the ground 3 be prevented, but also the lower part of the capsule body 1 can be used effectively as a parking lot, etc. can be achieved. In addition, by placing a ballast at the bottom of the capsule body 1, the radiation method can be immersed underground with water sprinkled from the sprinkler, and the ballast can have a radiation shielding effect. The present invention allows the shelter to be used as an office by opening the daylighting window 9 and using the protective door 2 as an entrance/exit part in normal times, and when the temperature inside the capsule body reaches a certain temperature (1, for example, 28 degrees Celsius or more in the summer), the temperature sensor 20 works to open a valve (not shown) from the water supply tank 10 to allow the sprinkler 8 to spray water from the roof of the capsule body to cool it.
During snowfall in winter, the pressure sensor 20 is activated when the snowfall exceeds a certain degree and the sprinkler sprinkles water to melt the snow on the capsule body.

On the other hand, in the event of an emergency due to an earthquake or nuclear explosion, the steel plates on the outside of the protective door 2 and the lighting window 9 are closed, thereby withstanding the external pressure caused by the nuclear explosion, and an automatic valve is activated by a pressure sensor based on a certain explosive force or a Geiger counter that detects radioactivity. It is possible to clean the capsule body of contaminated dust such as radioactive ash after the explosion so that it does not accumulate on the capsule body by opening the capsule or by sprinkling water from the water supply tank using a manual valve.

As an example of the specific function of the above-mentioned shelter, withstand pressure 0

However, children are calculated as 172 rn of adults)>
4 hours 20 minutes, filtration saturation power 99.998 against poisonous gases, germs, bacteria and radioactive substances.
% weight method. To explain filtration filters here, there are pre-filters with pressure-resistant valves and gas filters.Firstly, with pre-filters with pressure-resistant valves, the lid closes due to sudden external pressure such as an explosion, avoiding unnecessary pressure inside the capsule. It is designed to prevent damage to various equipment, and can filter not only particles of about 25 microns that can be seen with the naked eye, but also fine atmospheric debris and bacteria of about 3 microns with an efficiency of 85% by gravimetric method. The gas filter, which is the main material, removes 99.995% of light and fine particles, from cigarette smoke of 0.3 to 1 micron, to bacterial particles of 3 micron or less, metal welding smoke, and most poisonous gases.
It is possible to remove up to % weight method.

<Effects of the Invention> The shelter of the present invention can be used not only as an office in normal times, but also as a disaster prevention shelter in emergencies, and can also be used as a disaster prevention shelter with sprinklers installed on the roof of the capsule body. - allows the inside of the capsule body to be cooled by sprinkling water or the like in the summer, and also prevents loads due to snow accumulation or the like in the winter to avoid overloading the capsule body.

Further, in the present invention, a sprinkler can be activated in the event of a nuclear explosion, etc., and can function as a conventional sprinkler, such as cleaning and extinguishing dust such as radioactive ash.
