Description

Fire suppression apparatus for vehicle}

The present invention relates to a fire suppression device for a vehicle, and more particularly, by transferring the explosion-proof case provided on the bogie to the fire vehicle side and then covering the exterior of the fire vehicle, blocking the inflow of air flowing into the explosion-proof case when a fire occurs It relates to a fire suppression device for a vehicle that can effectively extinguish a fire by doing so.

In general, a high-voltage battery is mounted on a vehicle that uses electric power as a driving source or one of the driving sources, such as an electric vehicle (EV), a hybrid electric vehicle (HEV), and a plug-in hybrid electric vehicle (PHEV).

In the high voltage battery, a plurality of battery cells are stacked to form a battery pack, and very high power is generated. The biggest problem in using a high-voltage battery is that measures against overcurrent are required. Typically, a BMS (Battery Management System) is installed in an electric vehicle to cool itself when the battery pack heats up to a high temperature, and to cut off the power supply when an overcurrent occurs. Nevertheless, vehicle fire accidents due to heat from the battery pack often occur.

In particular, since electric vehicles contain the risk of explosion in case of fire, there is a need to develop an unmanned fire suppression system capable of quickly extinguishing a vehicle fire.

1 is a block diagram of a fire suppression apparatus for a vehicle according to an embodiment of the present invention, and FIG. 2 is a diagram illustrating an example of use of the fire suppression apparatus for a vehicle shown in FIG. 2 .

1 to 2, the vehicle fire suppression device 100 is for suppressing a fire vehicle 10 located outdoors such as an outdoor parking lot or road, and an explosion-proof case 110, a bogie 120, It may include a transfer unit 130 , a spray nozzle 140 , and a camera module 150 .

The vehicle 10 to be evolved in this embodiment includes a vehicle using fossil fuel as an energy source, a battery pack, and an electric vehicle using electricity as an energy source, electricity and fossil fuel together. It can be applied in various ways, such as a hybrid vehicle.

The explosion-proof case 110 covers the outside of the fire vehicle 10 to block the inflow of air. An accommodating space may be formed in the . For example, the explosion-proof case 110 may be formed using high-strength steel or a composite material having good heat resistance. In addition, a coupling part 111 for coupling with a transfer part 130 to be described later may be provided on the upper portion of the explosion-proof case 110 .

The lower portion of the explosion-proof case 110 may be fixed to the ground through a separation preventing member. For example, the explosion-proof case 110 may be fixed to the ground in a way that presses the explosion-proof case 110 using a spike-type wedge-fitting device (hydraulic type), a clamp member 233 of the transfer unit 130 to be described later, etc. have. In this way, as the explosion-proof case 110 is fixed to the ground, it is possible to prevent the explosion-proof case 110 from being separated from the fire vehicle 10 by the high-pressure extinguishing agent used when extinguishing a fire, and the ground and the explosion-proof case By minimizing the gap between the 110 , it is possible to more effectively block the air flowing into the explosion-proof case 110 .

The bogie 120 is movably formed in a state in which the explosion-proof case 110 is accommodated, and a fire extinguishing agent storage tank 121 may be provided on one side. For example, the bogie 120 may be provided as a wheel type or a caterpillar type formed to be drivable by a plurality of tires, and a storage space may be provided on the upper portion so that the explosion-proof case 110 can be accommodated. .

The transfer unit 130 is for lifting the explosion-proof case 110 from the bogie 120 and transferring it to the fire vehicle 10 side, and includes a boom body 131, a boom stand 132, and a fastening member 133. can

The boom body 131 may be coupled to the bogie 120 , and an accommodating space may be formed therein so that a plurality of booms 132 can be drawn in and out. For example, the boom 132 may be stretched and contracted using a hydraulic power pack (HPU), and may be manufactured using high-strength steel for vehicles.

The boom stand 132 is provided in plurality and may be provided in a folded state in the receiving space of the boom body 131 , and may be provided with a variable length in one direction. That is, according to the distance between the fire vehicle 10 and the bogie 120 , the boom body 131 is drawn out from the boom body 131 so that it can be located close to the fire vehicle 10 side. On the other hand, although not shown, the end of the boom stand 132 may be further provided with a link structure articulated boom. In this case, since the upper portion of the explosion-proof case 110 can be pressed by using a refraction boom when extinguishing a fire, it can serve as the above-described separation preventing member.

The fastening member 133 is to be coupled to the explosion-proof case 110 , and may be connected in a tension-controlled manner by a wire 134 provided at the end of the boom stand 132 . For example, the fastening member 133 may be provided as a hook or a winch, and may be directly connected to the explosion-proof case 110 using a coupling pin if necessary. And, the wire 134 coupled to the fastening member 133 is wound around the driving wheel, so that the tension of the wire 134 can be adjusted by unwinding or winding the wire 134 according to the rotational direction of the driving wheel.

Accordingly, when the boom 132 is extended while the fastening member 133 is caught on the coupling part 111 of the explosion-proof case 110, the explosion-proof case 110 is moved to the fire vehicle 10 side, and in this state If the wire 134 is released and the explosion-proof case 110 is moved to the lower side, the explosion-proof case 110 can cover the fire vehicle 10 (see FIG. 2 ).

As such, as the fire vehicle 10 is covered by the explosion-proof case 110 , the inflow of air into the explosion-proof case 110 is blocked, thereby preventing the fire from spreading. In addition, it is possible to prevent human accidents due to the explosion of the fire vehicle 10 .

A plurality of injection nozzles 140 are installed inside the explosion-proof case 110 to receive the extinguishing agent from the extinguishing agent storage tank 121 and to be positioned so that the extinguishing agent can be sprayed toward the ignition point of the fire vehicle 10 . can be

For example, the plurality of spray nozzles 140 may be installed to be spaced apart from each other, and may be connected in communication with the fire extinguishing agent storage tank 121 by the first pipeline 160 . In addition, an extinguishing agent control valve 161 for controlling the supply amount of the extinguishing agent may be installed in the first pipeline 160 . Accordingly, it is possible to control the supply amount of the extinguishing agent according to the degree of fire by adjusting the opening rate of the extinguishing agent control valve 161 .

Meanwhile, the bogie 120 may further include at least one of a water storage tank 122 and an inert gas storage tank (not shown), and at least one injection nozzle 140 by the second pipeline 170 . may be connected in communication with the water storage tank 122 or the inert gas storage tank.

For example, when the bogie 120 includes both the water storage tank 122 and the inert gas storage tank, the second pipeline 170 includes a water supply line 171 and an inert gas supply line 172 . can do. In addition, the water storage tank 122 is communicatively connected to at least one of the plurality of injection nozzles through the water supply line 171 , and the inert gas storage tank is connected to the remaining injection nozzles through the inert gas supply line 172 . It can be communicatively connected. Here, the water stored in the water storage tank 122 may be provided as cooling water, and the inert gas stored in the inert gas storage tank is helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon ( Xe), radon (Rn), may be provided as one selected from nitrogen (N2).

As such, when cooling water or an inert gas is provided along with the extinguishing agent, the fire suppression can be more easily performed by lowering the inside of the explosion-proof case 110 to a temperature below the ignition point or removing oxygen. In this case, the first pipeline 160 and the second pipeline 170 may be connected to each other in communication with the plurality of spray nozzles 140 through the distributor.

The camera module 150 may be installed in the explosion-proof case 110 to photograph the fire vehicle 10 . For example, a plurality of camera modules 150 may be installed on the inner upper portion of the explosion-proof case 110 to photograph the fire vehicle 10 , and the user may monitor the image captured by the camera module 150 and perform suppression work. can In this way, the fire site can be quickly identified through the captured image, so that the suppression operation can be performed efficiently. In this case, the camera module 150 may further include an LED module to illuminate the inside of the dark explosion-proof case 110 .

On the other hand, although not shown, the explosion-proof case 110 may further include a smoke exhaust device capable of discharging the harmful gas inside when the fire is suppressed through the spray nozzle 140 to the outside. As such, as harmful gas is discharged to the outside through the exhaust device, it is possible to solve the difficulty of photographing due to harmful gas when photographing the inside of the explosion-proof case 110 using the camera module 150, and later, the explosion-proof case 110 ), it is possible to prevent in advance the accident of poisoning by the harmful gas leaking out all at once.

Figure 3 is a side view of the spray nozzle provided in the explosion-proof case of Figure 1;

Referring to FIG. 3 , the injection nozzle 140 may include a link member 141 formed to be articulated so that the position can be adjusted. Specifically, the link member 141 may include a fixing bar 41 and a link bar 42 .

The fixing bar 41 may be formed in a bar shape having a hollow therein, and may be coupled to the upper portion of the explosion-proof case 110 .

The link bar 42 may be hollow inside to communicate with the fixing bar 41 , and may be hinged to one side of the fixing bar 41 to be movable toward the fire vehicle 10 . For example, a rotary motor, a hydraulic cylinder, a pneumatic cylinder, etc. are installed between the fixed bar 41 and the link bar 42 , and the link bar 42 may be rotatably connected from the fixed bar 41 . That is, the link bar 42 can be rotated upward or downward from the fixed bar 41 by the rotating motor or cylinder, and by controlling the rotation angle, the fire extinguishing agent can be sprayed to a desired site.

On the other hand, the injection nozzle 140 may be provided with a sharp end so that the fire extinguishing agent can be directly sprayed into the fire vehicle 10 by puncturing the cover of the fire vehicle 10 . That is, in the case of electric vehicles, most of the fires occur in battery packs or hydrogen tanks. When the cover of the fire vehicle 10 is punctured through the injection nozzle 140, the fire is extinguished directly in a local area such as a battery pack or a hydrogen tank. Since it is possible to spray the chemical, it is possible to proceed with fire suppression more effectively.

4 is a block diagram of a vehicle fire suppression apparatus according to another embodiment of the present invention, FIG. 5 is a diagram illustrating an example of use of the vehicle fire suppression apparatus illustrated in FIG. 4 , and FIG. 6 is a vehicle fire suppression apparatus illustrated in FIG. 4 It is a diagram schematically showing a fire suppression process using a fire suppression device. In this embodiment, the difference from the previous embodiment will be mainly described.

4 to 6 , the vehicle fire suppression device 200 is for suppressing the fire vehicle 10 located in a limited space such as an underground parking lot, and a track formed to be drivable by a pair of crawlers It may include a bogie 220 of a tracked type. In addition, an opening 110a for allowing the fire vehicle 10 to enter and exit is formed on one side of the explosion-proof case 110 accommodated in the bogie 220 , and the opening 110a may be shielded by the shutter 112 . have.

Due to the limited height of the space in which the fire vehicle 10 is located, the transfer unit 230 provided in the vehicle fire suppression device 200 may have difficulty in withdrawing the boom 132 when it is of the boom 132 type. Accordingly, in the case of the fire vehicle 10 located in a limited space, it is preferable to include a crane type transfer unit 230 .

The crane type transfer unit 230 may include a support unit 231 , a moving member 232 , and a clamp member 233 .

The support part 231 may be formed in the shape of a bar having a length in one direction, and may be vertically coupled to the upper portion of the bogie 120 .

The movable member 232 may be formed to be withdrawn from the support 231 and may be linked to a joint movement. For example, the moving member 232 may move vertically from the support 231 by a hydraulic cylinder or a rotary motor.

The clamp member 233 may be coupled to the distal end of the moving member 232 to grip a portion of the explosion-proof case 110 . For example, the clamp member 233 may pull out the explosion-proof case 110 from the bogie 120 by holding the coupling part 111 provided on the upper part of the explosion-proof case 110 , and move the bogie 120 . Then, the explosion-proof case 110 can be moved toward the fire vehicle 10 by pushing the rear end of the explosion-proof case 110 (refer to FIG. 6(b) ). At this time, the shutter 112 provided on one side of the explosion-proof case 110 may be in an open state. Accordingly, when the explosion-proof case 110 moves toward the fire vehicle 10 through the clamp member 233 , the fire vehicle 10 passes through the opening 110a to be positioned inside the explosion-proof case 110 . (see Fig. 6(c)). Thereafter, if the fire extinguishing operation is performed after the opening 110a is blocked using the shutter 112 , it is possible to safely extinguish the fire in the vehicle 10 without introducing air.

The clamp member 233 may be formed to press the upper portion of the explosion-proof case 110 in order to prevent the explosion-proof case 110 from being separated by the extinguishing agent provided at high pressure when the fire is suppressed through the spray nozzle. Accordingly, the explosion-proof case 110 can be in close contact with the ground by the self-weight of the explosion-proof case 110 itself and the pressing force of the clamp member 233, which more effectively prevents airtightness and separation inside the explosion-proof case 110 can be implemented.

On the other hand, when the fire suppression of the vehicle 10 is completed, the vehicle 10 together with the explosion-proof case 110 may be loaded on the bogie 220 through the transfer unit 230 and towed outside the parking lot.

As described above, the vehicle fire suppression apparatus 100 covers the outside of the fire vehicle 10 by using the explosion-proof case 110 when the fire vehicle 10 is suppressed, thereby blocking the inflow of air to prevent a fire in the vehicle. can be suppressed more effectively.

In addition, depending on the indoor or outdoor, the explosion-proof case 110 is lifted using the boom 132 or the explosion-proof case 110 is lifted using a crane and transferred to the fire vehicle 10 side. There is an advantage that it can be used without any restrictions on the location.

In addition, as the injection nozzle 140 is provided with the link member 141 formed to allow joint movement and is formed so that the position can be adjusted, it is possible to spray the extinguishing agent according to a desired position.

In addition, as the tip of the injection nozzle 140 is sharply provided and formed so that the cover of the fire vehicle 10 can be perforated, the fire extinguishing agent can be directly sprayed on the local area such as the battery pack or hydrogen tank where the fire first occurred. This allows for more efficient fire suppression.

In addition, by having a release preventing member capable of fixing the explosion-proof case 110 to the ground, it is possible to prevent the explosion-proof case 110 from being separated from the fire vehicle 10 by the extinguishing agent provided at high pressure.

Although the present invention has been described with reference to one embodiment shown in the accompanying drawings, it will be understood that this is merely exemplary, and that various modifications and equivalent other embodiments are possible therefrom by those skilled in the art. will be able Accordingly, the true scope of protection of the present invention should be defined only by the appended claims.
