DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a security room,
More specifically, the present invention relates to a security room having a fire prevention function used in a building for displaying and storing important articles such as art museums and museums, valuable articles, and the like.

[0002]

2. Description of the Related Art In order to protect valuable and expensive works and exhibits which cannot be replaced from fire in the art museums and museums described above, the walls are made of fire-resistant and heat-insulating materials having a sufficient thickness, The wall is made thicker than the building.

[0003]

However, in the case of the above-mentioned conventional fire protection system, it can be said that it has a considerable fire protection function as compared with a normal building, but it cannot be said that it is sufficient and it has been once generated. There is no resistance to fire. In this case, it is not preferable to use water for fire extinguishing because the work may be damaged. Therefore, the present invention provides a sufficient heat insulating effect by maintaining the wall surface at a low temperature at all times, and in the event of a fire, flushing the hollow walls, doors and windows, and further deaeration of the room. It is an object of the present invention to provide a security room capable of extinguishing a fire by extinguishing the fire, thereby ensuring that the exhibited works and the like can be reliably protected from fire.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a vacuum fire door and a fire vacuum window door are provided at openings such as doorways and windows to hermetically close them, and a vacuum is applied to make the interior of the room vacuum. An exhaust device is installed, and the fireproof vacuum door, the fireproof vacuum window door and the wall are hollowed and communicated,
Further, means for detecting an abnormal situation such as a fire is provided in the room.
The fire prevention vacuum based on a detection signal from the detection means.
The door and the fire prevention vacuum window door can be automatically closed and
The room is evacuated, and based on the detection signal,
The above-mentioned problem has been solved by a security room in which water can flow through a fireproof vacuum door, a fireproof vacuum window door, and a wall surface in a communicating state . Preferably, means for supplying nitrogen gas is provided in the room.

[0005]

[Operation] When an abnormal situation such as a fire occurs, the fire prevention vacuum door and the fire prevention vacuum window door close to close the room, and at the same time, water enters the hollow walls, the fire prevention vacuum door, and the fire prevention vacuum window door. Flow and they are kept cool. Further, the vacuum exhaust device operates to evacuate the inside of the room. Further, when nitrogen gas is supplied, the inside of the room is cooled and the fire is reliably extinguished.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan view showing the configuration of a security room 1. A plurality of security rooms 1 are provided in series via a fireproof vacuum door 2 for maintaining airtightness. The security room 1 is provided with windows 3 as appropriate, and each window 3 is provided with a fireproof vacuum window door 4 of a vertical sliding type which maintains airtightness. Each of the fire prevention vacuum door 2 and the fire prevention vacuum door 4 in FIG. 3 is lowered and closed.

The wall 5 of the security room 1 is a watertight hollow wall. The wall 5 is entirely in communication so that water can circulate. Fire protection vacuum door 2
Also, the fire prevention vacuum window doors 4 are hollow, and
Are connected to each other by a flexible tube 6 (see FIG. 2), so that water flowing in the wall surface 5 also flows to the fire-resistant vacuum door 2 and the fire-resistant vacuum window door 4.

Reference numeral 7 denotes a water tank, and water in the water tank 7 is pumped to a water supply passage 9 by a pump 8. The water supply passage 9 is connected to the inside of the wall surface 5 through a water supply port 10 provided in each security room 1. Each security room 1 is provided with a drainage port 11 in which water flowing through the wall 5 is collected and returned to the water tank 7 through a drainage channel.

Reference numeral 12 denotes a nitrogen gas tank. The nitrogen gas stored therein is introduced into each security room 1 through a pressure regulating valve 13 and a solenoid valve 14. In addition, an evacuation device 15 is installed in each security room 1 so that the inside of the room can be evacuated. A heat exchanger 16 for flowing water collected at the drain port 11 is attached to the evacuation device 15.

Further, a humidity controller 17 and an air conditioner 18 are provided in each security room 1, respectively.
Humidity and temperature within the room are maintained within predetermined ranges.

Although the security room 1 having the above structure may be provided only in one room, it is usually provided in a plurality through a fireproof vacuum door 2 and is used for an art museum or a museum. In a normal state, the inside of the room 1 is maintained at an appropriate temperature and an appropriate humidity by a humidity controller 17 and an air conditioner 18.
All the wall surfaces 5 and the fireproof vacuum doors 2 and the fireproof vacuum window doors are hollow.

When the temperature inside the room 1 becomes abnormally high due to the occurrence of a fire or the like, or when smoke is generated, the occurrence of such an abnormal situation is detected by a sensor disposed in the room 1. Is detected, the fire-prevention vacuum door 2 and the fire-prevention vacuum window door 4 are lowered to close the openings in an airtight state,
Seal the room 1. At the same time, the vacuum evacuation device 15 operates to evacuate the interior of the room 1 to a vacuum state.

If there is nitrogen gas supply means, the solenoid valve 14 is opened at the same time, and nitrogen gas is supplied into each room 1 to cool the inside of the room 1. In addition, water starts to flow simultaneously with the occurrence of fire in the wall surface 5, the fireproof vacuum door 2, and the fireproof vacuum window door 4, and the low temperature state is maintained.

As described above, when a fire or the like occurs, the interior of the room 1 is immediately rendered anaerobic and cooled, so that the fire is immediately extinguished. Even when there is no fire or the like, if the room air and the nitrogen gas are replaced by vacuum (the interior is evacuated and the nitrogen gas is supplied), it is effective for preservation of works of art and the like.

[0015]

The present invention is as described above. Even if an abnormal situation such as a fire occurs in the room, the room is automatically and immediately evacuated and cooled. In addition, the fire can be instantly extinguished, and the exhibits in the room can be protected from the fire without any damage. This is a security suitable for use in museums and museums. -Room is obtained.
