Description

The 20th century was a century in which material civilization was greatly developed, but on the other hand, it was a century of mass weapons killed by the emergence of modern weapons, especially nuclear weapons, and the subsequent threat of human death due to nuclear proliferation. Despite knowing that the threat of nuclear proliferation will stop in the 21st century, terrorists are now trying to get nuclear weapons. The present invention relates to a nuclear shelter for protecting life against such threats.

Japanese Patent Publication No. 2-42992 JP-A-8-112373 JP 11-336373 A Japanese Patent No. 2919111 JP 2000-54666 A Japanese Utility Model Publication No. 2-118571

The present invention is equipped with a neutron shielding function for protecting a life from a large amount of neutrons generated in a fission reaction in a low pressure chamber that can be used not only by a decompression training facility for specific athletes but also by general users on a daily basis. Relates to a low-pressure chamber with a nuclear shelter.

The present invention is the low-pressure chamber with a nuclear shelter function that covers the periphery of the low-pressure chamber housing with a mantle, fills the mantle with water, and shields neutrons generated in the fission reaction. It is characterized by.

According to a second aspect of the present invention, there is provided a water filtration and water supply function so that water filled in a jacket around the low-pressure chamber housing can be used as emergency drinking water or domestic water in an emergency. It is a low-pressure chamber with a nuclear shelter function.

The invention according to claim 3 is the low-pressure chamber with a nuclear shelter function according to claims 1 and 2, wherein a high-performance filter is connected to the outside air inlet of the low-pressure chamber to filter contaminants such as dead ash. .

Conventionally, the low-pressure chamber has been used only for the purpose of realizing a high-pressure atmosphere on a flat ground, but in the present invention, the low-pressure chamber casing is covered with a mantle and the mantle is filled with water for fission reaction. It has a water filtration and water supply function to shield generated neutrons and use the water filled in the mantle as emergency drinking water or domestic water, and a high performance filter is connected to the outside air inlet of the low pressure chamber. It is equipped with a function to filter out contaminants such as dead ash, so when a evacuation order is issued based on the outbreak of nuclear war and nuclear attack information while using the low pressure chamber for the original purpose of use in the low pressure chamber, By evacuating to the low pressure chamber, neutron exposure due to fission reaction can be avoided, and then the contaminated air due to death ash fall etc. can be filtered with a high performance filter, and the water filled in the mantle is filtered to be used as drinking water and domestic water Since it use, it is possible to maintain the precious life over a long period of time.

The best mode for carrying out the invention will be described. FIG. 1 is an elevational sectional view of a low pressure chamber with a nuclear shelter function to which the present invention is applied, FIG. 2 is a left side view of a low pressure chamber with a nuclear shelter function to which the present invention is applied, and FIG. 4 is a right side view of the low pressure chamber with a shelter function, FIG. 4 is a plan view of the low pressure chamber with a nuclear shelter function to which the present invention is applied, and FIG. 5 is a right elevation sectional view of the low pressure chamber with a nuclear shelter function to which the present invention is applied. FIG. 6 shows a piping system diagram of a low pressure chamber with a nuclear shelter function to which the present invention is applied.

In the embodiment of the low-pressure chamber with a nuclear shelter function of the present invention, a main structure is made up of a casing (2) having a strength capable of withstanding low pressure and a mantle (3) covering the periphery of the casing (2), Outer end plates (4a) and (4b) are tightly coupled to both ends of the housing (2). End plates openings (5a) and (5b) are respectively provided in the jacketed end plates (4a) and (4b), and the jacketed airtight doors (6a) are provided in the end plate openings (5a) and (5b). ), (6b) are provided so as to be airtight and openable and closable, and the end plates (4a), (4b) with the cloak and the airtight doors (6a), (6b) with the cloak are the airtight doors (6a) with the cloak, An airtight structure is formed by arranging packing (not shown) around (6b) and bringing it into close contact with the jacketed end plates (4a) and (4b).

Next, the neutron shielding means will be described. A jacket (3) covering the periphery of the low-pressure chamber casing (2), a jacket of the end plates (4a), (4b) with the jacket, and a jacket of the hermetic doors (6a), (6b) with the jacket. Is filled with drinking water (not shown) in advance, and the neutron shielding function of the water allows the person entering the low pressure chamber to avoid neutron exposure that occurs during fission.

After the above fission reaction, it can be easily estimated that the infrastructure will be destroyed and the lifeline will not be secured. At this time, the jacket covering the low pressure chamber (1) casing (2) is covered. (3) In order to be able to use the water filled in the outer cover of the outer plate with the outer cover (4a), (4b) and the outer cover of the outer cover with the outer cover (6a), (6b) as drinking water and domestic water, The jacket is connected to an emergency power supply facility (43) and a water supply pump (44) equipped with a water filtering device (45) at the discharge port, respectively.

In addition, after the fission reaction, air pollution due to death ash fall or the like can be easily estimated, but the outside air intake ports (19) to (23) provided in the low pressure chamber (1) casing (2) have high performance. Since the activated carbon filter (30) and the HEPA filter (31) are connected, contaminants in the air can be completely filtered, and the resident in the low-pressure chamber can ensure safety from above the air.

In terms of industrial applicability, it is expected to be widely used not only for general households, but also for schools, gyms, hotels, hot springs, golf rest houses, hospitals, osteopaths, nursing homes, professional athletes, low-pressure room service shops, etc. The However, this is an extreme measure of life support, and we must make every effort to bring together a permanent peace where such devices do not need to function.
