As shown, the fire extinguishing system 100 of the present invention includes at least one pillar portion 120 made of a flexible material and provided with at least one through hole 124; and a rim 130 that is supported between the pillars 120 and surrounds the vehicle, wherein the pillar 120 is a hollow shape whose shape is changed by fire extinguishing fluid or water, and is located on the side or side of the vehicle. A flexible fire extinguishing system (100) for fire in a vehicle is provided, characterized in that it acts as a supply medium for supplying fire extinguishing liquid or water to the upper part.

The fire extinguishing system 100 of the present invention is transportable, so it is easy to install around the vehicle when the vehicle is ignited. In addition, when it is fixedly installed at a gas station, parking lot, etc., it can be maintained seated inside the rim of the fire extinguishing system 100 even before the vehicle ignites, and can be activated when ignited. That is, the fire extinguishing system 100 of the present invention can be of a mobile type or a fixed type. When the fire extinguishing system 100 is fixedly installed, it may further include a bottom 110, and the bottom 110 forms a part of the fire extinguishing system 100 and supports the fire extinguishing system 100 from the bottom. Alternatively, the bottom portion 110 may form part of the floor surface on which the fire extinguishing system 100 is fixed. Alternatively, the fire extinguishing system 100 is configured to be embedded and may be part of a border surrounding a parked vehicle.

For example, the pillar portion 120 may be formed at each vertex of a square so that the fire extinguishing system 100 has an overall square plane, or may be arranged to form a circle. That is, the arrangement method of the pillar portion 120 is not particularly limited, and the number of pillar portions 120 is also not limited.

The edge portion 130 is connected between the pillar portions 120. Only the pillar portion 120 may be manufactured in a hollow shape, and the edge portion 130 may also be manufactured in a hollow shape. However, since it takes time for the edge portion 130 to be filled with fire extinguishing fluid or water, in an emergency situation, it is preferable to fill only the pillar portion 120 with fire extinguishing fluid or water.

Since the fire extinguishing system 100 of the present invention has overall flexibility, it can be made of various deformable materials such as artificial leather, leather, polymer, silicon, etc. There are no restrictions on the material, but since it is used for vehicle fires, It must be a flame retardant material. It is desirable that the flame retardant material is a product that has obtained KFI (Korea Fire Industry & Technology Institute) certification. The reason it has flexibility is that it normally maintains a contracted state because there is no digestive fluid, but when digestive fluid or water is injected into the hollow interior of the pillar portion 120, the pillar portion 120 gradually expands and forms a shape with the edge portion 130. This is because they are configured to grow together to exceed the height of the top of the vehicle.

In order to deform the column portion 120 by water pressure, an injection path for fire extinguishing fluid or water is required. A distribution port 140 through which fire extinguishing fluid or water enters and exits is further formed at least on one lower side of the column portion 120. . Extinguishing liquid or water may be injected or discharged through the distribution port 140. It is advantageous for the pillar portion 120 to take shape if possible if installed at the bottom.

The distribution port 140 may be equipped with a stopper to enable opening and closing. In addition, the distribution port 140 may be formed at the bottom of the edge portion 130, for example. That is, the edge portion 130 has a hollow shape, and its shape is changed by fire extinguishing fluid or water, and a through hole 124 is formed on one side to allow fire extinguishing fluid or water to be supplied from it, thereby forming the edge portion ( In addition to supporting the pillar portion 120 and confining fire extinguishing fluid or water, 130) may also play a role of actively participating in extinguishing a ignited vehicle. However, as described above, it is more advantageous to have a non-hollow shape so that fire extinguishing liquid or water is supplied only to the pillar portion 120, in that it allows rapid fire extinguishing.

Meanwhile, a ventilation hole 150 is further formed in the pillar part 120, and the ventilation hole 150 serves to enable the pillar part 120 to stand upright at a faster speed. When erecting the pillar 120 by injecting fire extinguishing liquid or water through the distribution port, the injection speed of the liquid is slower than the injection speed of the gas, so in an emergency situation requiring rapid fire extinguishment, it is necessary to erect the pillar 120 first. . In this case, the pillar part 120 is first erected, and then the distribution port 140 is immediately opened to inject fire extinguishing liquid or water, so that the fire extinguishing liquid is immediately sprayed. As shown, the distribution port 140 is located in the lower part of the pillar part 120, but may be formed in the upper part of the pillar part 120 (not shown). In this case, the through hole is formed in the upper part of the pillar part 120. When 124 is formed, fire extinguishing liquid or water supplied from the top may be discharged through the through hole 124 at the top.

The pillar part 120 is bent or curved so that when fire extinguishing liquid or water is filled inside, the upper end is located inside the boundary of the base compared to the lower end. In this case, the fire extinguishing liquid is released from the upper end of the pillar part 120. Alternatively, the hole 124 through which water is discharged is directed toward the vehicle. Therefore, it is possible to more accurately and sufficiently supply fire extinguishing fluid or water to the vehicle.

The pillar part 120 is further provided with a partition wall 122 therein, and the upper end of the partition wall 122 is preferably spaced apart from the upper inner wall of the pillar part 120 at a predetermined distance. This is so that the partition wall 122 forms an injection path for extinguishing liquid or water. That is, the fire extinguishing liquid or water is first supplied and filled to the outside of the partition wall 122 at a position far from the vehicle relative to the vehicle, and after the fire extinguishing liquid or water is completely filled on the outside of the partition wall 122, the partition wall 122 is discharged through the space separated from the vehicle. It moves inward, and since a through hole 124 is formed inside the partition wall 122, the fire extinguishing liquid or water is supplied to the vehicle through the through hole 124. The reason why the fire extinguishing liquid or water is first supplied to the outside of the partition wall 122 is to ensure that the pillar part 120 maintains its shape. The shape of the pillar part 120 must be maintained so that the fire extinguishing liquid or water can be supplied to the vehicle more easily. The importance of the upper partition 122 is great because it can be done effectively. If there is no partition wall 122, it may take more time for the pillar portion 120 to achieve the desired shape.

At this time, a backflow prevention film 123 is formed between the top of the partition 122 and the top inner wall of the pillar 120, and the fire extinguishing liquid or water filling the outside of the partition 122 reaches the top of the partition 122. Then, the fire extinguishing liquid or water is filled inside the partition wall 122 located close to the vehicle via the backflow prevention membrane 123. The entire amount of fire extinguishing liquid or water supplied to the inside of the partition 122 is not discharged through the through hole 124, and the remaining amount is discharged from the vehicle through the lower through hole 125 formed at the lower part of the pillar portion 120 toward the vehicle. Water is supplied from the bottom.

In other words, the fire extinguishing system 100 of the present invention can be expected to have the effect of quickly extinguishing the vehicle by supplying fire extinguishing liquid or water from both the upper and lower sides.

In addition, the present invention may have the partition wall 122 formed in this way, but can be operated even when the partition wall 122 is not formed as shown in FIG. 2(a). The pillar portion 120 can be operated only by the presence of the partition wall 122. ) is not limited.

In addition, the stomach reflux prevention film may also be formed in the distribution port 140 and the ventilation hole 150, and in this case, the reflux prevention film is designated by

reference numerals

141 and 151, respectively. Since the operating principles of the

backflow prevention films

123, 141, and 151 are all the same, additional explanation will be omitted below.

Meanwhile, by adjusting the diameter of the through hole 124, it can be used to extinguish a ignited vehicle differently as needed. If the diameter of the through hole 124 gradually decreases from the top to the bottom of the pillar portion 120, In this case, ignition occurs largely at the top of the vehicle. This means that increasing the amount of water supplied from the top is more helpful in extinguishing the fire when the ignition occurs in the mid-term or higher, and stronger water pressure is applied at the bottom and the water outlet distance can be increased. In this regard, there is an advantage in that water can be supplied further from the bottom of the vehicle. Therefore, among the solutions presented in FIG. 3, it would be more preferable to have a larger upper through hole 124 as shown in (b), but to implement a relatively smaller size of the upper through hole 124 as shown in (a). It is not excluded.

The through hole 124 is formed only at the upper part centered on the pillar portion 120, and supplies fire extinguishing fluid or water from the lower distribution port 140 to the lower part of the vehicle to trap the fire extinguishing fluid or water in the edge portion 130. This is advantageous when the upper part of the vehicle is responsible for extinguishing fire only at the upper part of the pillar 120, and water needs to be supplied from the lower part of the vehicle to the rest.

Among the edge portions 130, a water level adjuster 131 is further provided at a height lower than the height of the top of the driver's seat of the vehicle, and the water level adjuster 131 is formed at a height such that the driver's respiratory tract is not submerged in digestive juice or water. do. This is to prevent drowning accidents of the driver and passengers that may occur during the process of extinguishing the vehicle. This is preferably formed mainly on the edge portion 130.

The fire extinguishing system 100 is preferably connected to a receiving unit and a control unit so as to be interlocked with a fire detector. This is to enable the fire extinguishing system 100 to operate at the same time when the fire detector determines that it is a fire due to smoke, heat, etc. and issues a fire alarm. To this end, the control unit connected to the fire extinguishing system 100 and the fire detector must be able to communicate. It's good to connect. Communication methods are diverse and are known technologies, so there is no limitation to a specific method.

As described above, the present invention has been described in detail based on preferred embodiments. However, the above embodiments are only examples provided to explain the present invention in technical detail and do not represent the scope of the patent claims, so the patent claims of the present invention It will be obvious that the scope should not be construed as limited by these examples.
