Description

[Detailed explanation of the invention] [Field of industrial application] The present invention relates to a nuclear shelter, and more specifically, the invention is a nuclear shelter that is equipped with a main air chamber leading to the entrance/exit and an emergency exit, and an emergency air chamber leading to the emergency exit. This study concerns improvements to the nuclear sierra that attempted to protect the ward from nuclear contaminants from the outside.

[Conventional technology]

In addition to the main entrance and exit for normal use, nuclear siertas are equipped with emergency escape exits, and these entrances and exits are naturally equipped with airtight doors to ensure safety until it is possible to escape after nuclear contamination. Closed.

By the way, if the above-mentioned entrances and exits are connected directly to the living area, evacuees who enter the living area from outside after nuclear contamination will enter the living area in a contaminated state and cause secondary contamination of the living area. To prevent this, a main aerospace chamber and an emergency aerospace chamber are usually provided with an airtight door interposed between the entrance/exit and the living area.

In other words, due to the existence of the main aerospace chamber, evacuees from outside are first placed in this main aerospace chamber and isolated from the outside, ensuring safety quickly, and
In this situation, a proposal has been made to remove contaminants from evacuees before entering their rooms, thereby making the living area double-sealed.

Such a double-sealed nuclear silter, for example,
It is disclosed in Japanese Patent Application Laid-open No. 174569/1983.

Since the main aerodynamic chamber and the emergency aerodynamic chamber are provided, an escape port opening to the ground is provided above them.

[Problems to be solved by the invention] As mentioned above, it was hoped that the provision of the main airlock chamber and the emergency airlock chamber would be effective in preventing secondary contamination, but the following problem arose.

First of all, since the entrances and exits are double-sealed, it is not desirable for safety reasons to open the emergency exit directly into the living area.

Therefore, the first thing to do was to open the escape exits of the main aerospace chamber and the emergency aerospace chamber onto the ground, but these airtight doors would be heated by the high heat generated by the nuclear explosion. There is a high risk that the door will melt, deform, or seize, making it impossible to open or close it even if you operate it from the inside during the time when it is possible to escape after the bombing.

Second, the airtight door at the top of the main airlock room, which leads to the entrance for evacuation after an atomic bombing, is heated, and the air inside is heated to a high temperature through this airtight door. When a contaminated person enters the living area from the outside, there is no time for the body to remove the contaminant from the main air chamber.

That is, they are unable to remain in the main air chamber in hot air at all, or at least not for the sufficient amount of time necessary to clean themselves.

As a result, evacuees enter the living quarters immediately from the main aerospace room, which defeats the purpose of providing a main aerospace room.

In view of the above-mentioned conventional technology, the present invention has been developed to allow evacuees to sufficiently clean their bodies in the main air chamber leading to the entrance and exit, to prevent secondary contamination in the living area, and to provide a main air chamber that opens to the ground. The purpose is to ensure the function of the airtight door of the escape exit of the emergency aerospace room.

[Means to solve the problem]

In order to solve the problems of the prior art described above and achieve the objective, the nuclear shelter according to the present invention has a main aerospace chamber 2 connected to one side of a living area 1 provided with at least a living room 5 via a partition wall 12. , the partition wall 12 is provided with a communication port 16 leading to the living room 5 and an airtight door 19 for opening and closing the communication port 16; an entrance 21 is provided in the main air compartment 2;
An airtight door 22 that opens and closes the main airlock chamber 2 is provided, and an escape port 23 that exits to the ground is provided above the main airlock chamber 2, and the escape port 23 has an airtight door 25 that opens upward.
is provided, and a partition wall 1 is provided on the other side of the living area 1.
The emergency airlock chamber 4 is connected to the emergency airlock chamber 4 through the partition wall 10, and the partition wall 10 is provided with a communication port 14 leading to the living room 5, and an airtight door 18 for opening and closing the communication port 14. In the nuclear shelter, an emergency exit 24 is provided on the upper side leading to the ground, and the emergency exit 24 is provided with an upwardly opening airtight door 26. Water storage tanks 31 and 32 are installed above the airtight door 26 leading to the aerodynamic chamber 4, respectively.
In this case, the airtight doors 25 and 26 are constantly submerged in water.

[Effect]

With the above configuration, even if the upper part of the nuclear shelter is heated to a high temperature during an atomic bombing, the escape port 2 of the main aerospace chamber 2
It is a theory that the airtight door 25 of No. 3 and the airtight door 26 of the escape port 24 of the emergency airlock chamber 4 are directly protected by the water in the water tanks 31 and 32, and the airtight door is protected by heating and evaporation of the water. The temperature rise of 25 and 26 itself can be suppressed.

This prevents the airtight doors 25, 26 from melting, deforming, or burning, ensuring their functionality, and allowing them to be opened and closed easily from the inside afterwards.

In the main airlock chamber 2, heating of the airtight door 25 is suppressed, so that even when an evacuee enters the main airlock chamber 2, the indoor air does not reach high temperature and there is sufficient time for the evacuee to enter the main airlock chamber 2. The nuclear contaminants can then be cleaned and removed before entering the residential area.
