Abstract

PROBLEM TO BE SOLVED: To provide a highly-foaming fire extinguisher which miniaturizes a device and effectively and safely extinguishes a fire. SOLUTION: A highly-foaming fire extinguisher 5 manufacturing equipment is provided with mixed liquor manufacturing equipment 5a which stores a highly- foaming fire extinguishing liquor to feed a mixed liquor of this fire extinguishing liquor and water to an extinguishing object place where a fire occurs at the time of a fire and a foaming means 8 for feeding the mixed liquor fed by the equipment 5a to the extinguishing object place after highly foaming it. The extinguisher 5 is communicated with sections 2 (2n1 to 2n11) desired to ventilate with outside through blowing ducts 7 (7A1 to 7A11) for ventilation. Each of these ducts 7 is provided with a blower 6. The ducts 7 are normally used for ventilating these sections 2. Air path switching means 9 (9A1 to 9A11) are provided insides of the ducts 7. At the time of a fire, the means 9 send air sent from a blower to the side of the means 8 (8A1 to 8A11). Thus highly-foamed foam can be supplied to the extinguishing object place. Since the ducts 7 can be used for ventilation and extinguishing in common, the area of the duct required for extinguishing can be miniaturized.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a foam fire extinguishing apparatus which performs high foaming. More specifically, the present invention uses the ventilation blowing means for normally ventilating a predetermined section of the storage space also as the blowing means for foaming air, and when the fire occurs, the foaming air is supplied by the ventilation blowing means. The present invention relates to a high-foaming fire extinguishing apparatus that can be supplied.

2. Description of the Related Art Generally, an automobile or a container provided with a refrigeration system generates exhaust gas, flammable gas, and heat. Therefore, when storing or transporting the same, a space for storing these devices is required. Need to ventilate. On the other hand, when storing or transporting these devices, a fire may occur, so it is necessary to provide a fire extinguishing system.

For example, in a car carrier or a container carrier, a ventilation device for ventilating a storage space and a fire extinguishing system are provided. In such a ship type ship, as a fire extinguishing system, conventionally, a carbon dioxide gas extinguishing system was equipped, but as described above, the carbon dioxide gas extinguishing system is
Since people who were left at the fire site were more likely to die from the fire than from the fire, they were more likely to die of asphyxiation by carbon dioxide gas. And a technique for effectively transporting the foamed foam to a fire extinguishing target place has been proposed (Japanese Patent Laid-Open No.
No. 4904), application of such technology to ships having a special hull form is expected.

FIG. 11 is a view showing an example of a ship to which the above-mentioned conventional high foam fire extinguishing system is applied. In FIG. 11, a ship 101 is provided with an engine room 102, and the engine room 102 can be extinguished by a high-foaming fire extinguishing device 111. That is, the high foam fire extinguisher 111
Is a fire extinguishing liquid tank 112 for storing a fire extinguishing liquid, a water pump 113 for feeding water mixed with the fire extinguishing liquid, a mixing device 114 for mixing the fire extinguishing liquid and water, and a fire extinguishing liquid for sending the fire extinguishing liquid from the fire extinguishing liquid tank 112. It has a liquid pump 115, a blower duct 117 including a blower 116 for sending air for generating foam, and a foam generator 118 for generating a high expansion foam for extinguishing a fire extinguishing liquid and a mixture of water. .

[0005] Further, the place to be extinguished is communicated with the outside by the blower duct 117, and the blower 116 is disposed at an opening on the outside of the blower duct 117.
Reference numeral 18 is arranged at the opening of the ventilation duct 117 on the fire extinguishing target side. Further, the foam generator 118 is provided with the nozzle 1
19 and a foam net 120. This nozzle 119
Is connected to the mixing device 114 via a pipe 121.

According to the high-foaming fire extinguisher 111, a ventilation duct 117 in which a fire extinguishing target area and its outside are specially provided.
A foaming machine 118 for generating a foam of the fire extinguishing liquid is disposed near the opening of the blow duct 117 on the side of the fire extinguishing target, and air is blown by using a blower 116 provided at an external opening of the blow duct 117. The foaming machine 118 causes the foaming machine 118 to perform high foaming by using the fire extinguishing liquid and the fire generated by sending the foamed foam to the place where the fire occurs by the pressure generated by the blower 116.

According to such a conventional apparatus, the moving distance of the foam can be reduced, and the foam can be effectively sent to the place where the fire has occurred. Further, since the speed at which the air is sent by the blower can be made relatively high, the cross-sectional area of the opening of the blower can be reduced.

[0008]

However, the above-mentioned high-foaming fire extinguisher has two types of blowers, a normal ventilation blower (blower and blower duct) and a fire extinguishing blower (blower and blower duct). Such a configuration is not preferable because it requires the installation area of the device, which inevitably reduces the load.
Further, the ventilation blower and the fire extinguishing blower, in principle, when no fire occurs, the fire extinguishing blower is not required, only the ventilation blower is used, in the event of a fire,
Conversely, only a fire extinguisher blower is used, and a ventilation blower is not required. Therefore, there is no problem even if these devices for the purpose of blowing air are also used.
An object of the present invention is to provide a high-foaming fire extinguishing device that solves the above-mentioned disadvantages, reduces the size of the device, and enables effective and safe fire extinguishing.
