Description

Fire spread prevention and fire suppression apparatus for electric vehicle parking facility}

The present invention relates to a fire spread prevention and suppression device for electric vehicle parking facilities that can prevent the spread of fire and quickly extinguish the fire when a fire occurs in an electric vehicle being charged through an electric charging facility.

As environmental issues become increasingly important worldwide, the automobile industry is also releasing various types of vehicles incorporating eco-friendly technologies. Vehicles released by incorporating eco-friendly technology include hybrid cars, hydrogen cars, and electric cars, and among them, electric cars are receiving the most attention and are being widely sold.

In general, an electric vehicle refers to a vehicle that uses an electric motor as a power source instead of an internal combustion engine, unlike vehicles that run on an internal combustion engine such as a gasoline engine. At this time, in electric vehicles, the battery for charging and discharging electricity is mainly placed on the bottom of the vehicle. In this case, accidents frequently occur when the battery is shocked from the outside or suddenly overheats while charging at an electric charging station, leading to a fire.

In particular, in the case of electric vehicle fires, problems arise such as the fire taking a long time to extinguish, unlike general automobile fires, as fires occur continuously in multiple cells that make up the battery.

Therefore, there is a need for research and development on fire suppression systems specialized for electric vehicles rather than general automobile fire accidents.

Recently, as the use of electric vehicles increases, the incidence of electric vehicle fire accidents is also rapidly increasing.

Therefore, in the present invention, we will take a closer look at the device for preventing and suppressing the spread of fire in electric vehicle parking facilities, which is specialized for electric vehicle fires.

1 is a schematic diagram of a device for preventing and suppressing the spread of fire in an electric vehicle parking facility according to an embodiment of the present invention.

As shown in FIG. 1, the electric vehicle parking facility fire spread prevention and suppression device 100 according to an embodiment of the present invention includes a sensor unit 120, a control unit (not shown), a flame retardant fabric 140, and a water barrier wall 160. ) and a fire extinguishing water supply nozzle (180).

The sensor unit 120 is installed on the ceiling of the space where the vehicle electric charging facility (C) is installed, detects whether a fire occurs in the vehicle (V) being charged through the vehicle electric charging facility (C), and reports the detection result. Transmit to the control unit. This sensor unit 120 is disposed on the ceiling frame F installed along the vehicle, and includes at least one of a fire detection sensor, a smoke detection sensor, an oxygen concentration measurement sensor, and a temperature sensor.

The fire detection sensor detects heat or flame in the vehicle (V) and detects whether a fire has occurred in the vehicle (V).

A smoke detection sensor detects smoke generated from the vehicle (V). In the case of a fire in a vehicle, especially in the case of a battery fire, smoke may occur before heat or flames, so the occurrence of a fire in the vehicle can be detected at an early stage through the smoke detection sensor.

The oxygen concentration measurement sensor measures the oxygen concentration in the space surrounding the vehicle (V) after the inflow of air is blocked by the flame retardant cloth 140 installed around the vehicle (V). At this time, it can be determined whether the flame retardant fabric 140 is properly blocking the inflow of air into the surrounding space of the vehicle V through the oxygen concentration measured by the oxygen concentration measurement sensor.

The temperature sensor measures the internal temperature of the surrounding space of the vehicle V, where air inflow is blocked by the flame retardant fabric 140. At this time, the measured internal temperature information of the surrounding space of the vehicle V can be used to determine whether fire suppression is currently being performed smoothly and the possibility of additional fires occurring.

The control unit receives at least one sensing signal indicating whether a fire has been detected for the vehicle (V) from the sensor unit 120, and in response to the control signal for controlling the installation of the flame retardant fabric 140, the water barrier wall 160. A drive signal that controls the operation of the fire extinguishing water supply nozzle 180 and a turn-on signal that controls the on and off of the fire extinguishing water supply nozzle 180 are generated. In generating each signal, the control unit first generates and outputs a control signal for installing the flame retardant fabric 140, then generates and outputs a drive signal for driving the barrier wall 160, and finally, Turn-on signals for turning on and off the fire water supply nozzle 180 are generated and then output. In this way, the control unit generates each signal in the order of the control signal, the drive signal, and the turn-on signal, thereby preventing the spread of the fire and continuously extinguishing the fire.

The flame retardant fabric 140 is installed inside the frame (F) installed on the ceiling, and when the sensor unit 120 detects a fire in the vehicle (V), it descends from the ceiling to the floor, that is, in the vertical direction. Blocks air inflow into the surrounding space of the vehicle (V).

At this time, the frame (F) may include a suction fan (190) that sucks in smoke generated from the vehicle (V) and discharges it to the outside. A pipe may be formed inside this frame (F), one end of the pipe may be connected to the suction fan 190, and the other end of the pipe may be connected to the outside. Therefore, smoke sucked in through the suction fan 190 can be discharged to the outside along the pipe inside the frame.

The barrier wall 160 is embedded in the floor to surround the vehicle V, and when a fire occurs in the vehicle V, it protrudes from the embedded floor toward the ceiling at a predetermined height to protect the vehicle V. Seal the space around the lower part of the. At this time, the space around the lower part of the vehicle V may be, for example, a space around the wheels of the vehicle V.

The fire extinguishing water supply nozzle 180 is connected to an external fire hydrant and installed on the floor where the vehicle V is parked, and supplies fire extinguishing water to the space around the lower part of the vehicle V sealed by the water cutoff wall 160. Thus, the battery installed on the floor of the vehicle V is submerged.

Hereinafter, the flame retardant fabric 140 described above will be examined in more detail with reference to FIGS. 2 and 3.

That is, in normal cases in which a fire does not occur, the flame retardant fabric 140 is placed in a folded state inside the frame F installed on the ceiling, as shown in the area (a) on the right side of FIG. 2. However, when detecting a fire in the vehicle V, as shown in the area (b) on the left side of FIG. 2, the flame retardant fabric 140 disposed in a folded state inside the frame F is completely on the floor. By lowering it until it touches, the inflow of air into the surrounding space of the vehicle (V) is completely blocked. At this time, the portion indicated by a dotted line in the area of FIG. 2(b) indicates the height at which the barrier wall 160 protrudes from the trench T formed in the floor.

Figure 3 is a diagram illustrating the internal structure of a flame retardant fabric in a fire prevention and suppression device for an electric vehicle parking facility according to an embodiment of the present invention.

As shown in FIGS. 3(a) and 3(b), the flame retardant fabric 140 includes a substrate 142 and a cover 144.

The substrate 142 is made of a bellows-shaped support and has relatively high hardness.

The cover 144 is arranged to surround the front surface of the substrate 142 and is made of a flame-retardant material.

Therefore, when the flame retardant fabric 140 descends from the ceiling to the floor due to a fire in a vehicle and touches the floor, the base material 142 is installed so that the cover 144 of the flame retardant fabric 140 does not easily shake due to flame or smoke. can act as a support. Therefore, blocking air inflow of the flame retardant fabric 140 can be performed more effectively.

In addition, hereinafter, with reference to FIGS. 4 and 5, we will look in more detail at the water barrier among the devices for preventing and suppressing the spread of fire in an electric vehicle parking facility according to an embodiment of the present invention.

Figures 4 and 5 are cross-sectional views of the barrier wall of a fire prevention and suppression device for an electric vehicle parking facility according to an embodiment of the present invention.

As shown in “A” of FIGS. 4 and 5, the water cutoff wall 160 is buried inside the trench (T) formed at the bottom of the space where the vehicle (V) is usually parked. However, at this time, when the sensor unit 120 detects the occurrence of a fire in the vehicle V, as shown in “B” in FIG. 5, a pair of devices arranged to face each other at the entrance of the trench T The protrusion 10 rotates 90 degrees toward the bottom, and thus the water barrier wall 160 protrudes upward.

For example, the water blocking wall 160 may be connected to the bottom of the trench T through an elastic member. That is, the water blocking wall 160 whose protrusion is blocked by a pair of protrusions 10 disposed at the entrance of the trench (T) rotates toward the bottom of the trench (T) and at the same time, the elastic member It can protrude toward the ceiling due to elastic force.

Alternatively, the water barrier 160 may be formed in multiple stages inside the trench T. In this case, after the protrusion 10 is rotated 90 degrees toward the floor, the barrier wall 160 may be extended in multiple lengths to be equal to the wheel height of the vehicle V.

In this way, the barrier wall 160 protrudes to the same height as the wheel height of the vehicle (V) where the fire occurred, so that it is universal regardless of whether the vehicle (V) where the fire occurred is a general passenger car or SUV with different body heights. This can sufficiently submerge the battery mounted on the floor of the vehicle (V).

In addition, the water cutoff wall 160 includes a water level measurement sensor, and the water level measurement sensor can measure the water level of fire extinguishing water (W) supplied to the space around the lower part of the vehicle (V) in real time and transmit it to the outside. . Accordingly, the vehicle owner's mobile terminal can check the water level sensing information of the fire extinguishing water (W) measured by the water level measurement sensor from the outside, thereby confirming the fire suppression situation for the vehicle (V) in real time.

Hereinafter, with reference to FIG. 6, we will look at the cross-sectional structure of a device for preventing and suppressing the spread of fire in an electric vehicle parking facility according to an embodiment of the present invention.

Figure 6 is a cross-sectional view of a device for preventing and suppressing the spread of fire in an electric vehicle parking facility according to an embodiment of the present invention.

As shown in FIG. 6, when the sensor unit 120 formed on the ceiling frame (F) senses the occurrence of a fire in a charging vehicle, first, the flame retardant fabric 140 installed on the ceiling frame (F) is It descends in the vertical direction, blocking additional air inflow into the surrounding space of the vehicle (V). This flame retardant fabric 140 can prevent a fire occurring in the vehicle V from spreading to nearby people, other vehicles, or charging facilities.

Subsequently, the barrier wall 160 embedded along the periphery of the vehicle (V) where the fire occurred protrudes to seal the space around the lower part of the vehicle (V).

Afterwards, the fire extinguishing water supply nozzle 180 installed on the floor supplies the fire extinguishing water (W) to the space around the lower part of the vehicle (V) sealed by the water barrier wall (160), and the battery mounted on the floor of the vehicle (V) Extinguish the fire by flooding the area.

Therefore, as described above, the electric vehicle parking facility fire spread prevention and suppression device 100 according to an embodiment of the present invention uses the flame retardant fabric 140 to prevent the spread of fire occurring in the vehicle V to the surrounding area, and prevents the fire from spreading to the surroundings of the vehicle V, (160) The fire can be quickly extinguished by supplying fire extinguishing water (W) to the enclosed space.

In addition, the electric vehicle parking facility fire spread prevention and suppression device according to the present invention, when a fire occurs in the vehicle (V), extinguishes the fire suppression situation to the outside, that is, the driver's It can be checked in real time through the mobile terminal 300.

Hereinafter, with reference to FIG. 7, we will take a closer look at the device for preventing and suppressing the spread of fire in an electric vehicle parking facility according to another embodiment of the present invention.

Figure 7 is a schematic diagram of a device for preventing and suppressing the spread of fire in an electric vehicle parking facility according to another embodiment of the present invention.

As shown in FIG. 7, the device for preventing and suppressing the spread of fire in an electric vehicle parking facility according to another embodiment of the present invention includes the sensor unit 120, the control unit (not shown), and the flame retardant cloth 140 described in detail with reference to FIG. 1 previously. , In addition to the cutoff wall 160 and the fire water supply nozzle 180, it further includes a server 200 and a mobile terminal 300.

The server 200 senses from at least one of a water level measurement sensor included in the water barrier 160, a fire detection sensor, a smoke detection sensor, an oxygen concentration measurement sensor, and a temperature sensor included in the sensor unit 120 from the control unit. Receive information.

The mobile terminal 300 receives the sensing information from the server 200 and outputs it to the outside. At this time, the mobile terminal 300 may be the car owner's personal mobile terminal or a terminal placed inside the fire department. Accordingly, the car owner can determine the fire suppression status of the vehicle (V) covered by the flame retardant cloth (140) in real time by checking the sensing information output through his/her mobile terminal (300).

That is, the mobile terminal 300 can remotely determine whether a fire has occurred in the vehicle through fire detection information and smoke detection information among the sensing information received from the server 200. In addition, the mobile terminal 300 can know the current fire suppression situation in real time through oxygen concentration information and temperature information among the sensing information received from the server 200 even after the flame retardant fabric 140 and the barrier wall 160 are installed. . In addition, the mobile terminal 300 can check the flooding situation of the battery in the vehicle V in real time through water level measurement information among the sensing information received from the server 200.

In addition, the above-described electric vehicle parking facility fire spread prevention and suppression device 100 may have a different detailed configuration of the flame retardant fabric 140.

Figure 8 is a schematic diagram of a device for preventing and suppressing the spread of fire in an electric vehicle parking facility according to another embodiment of the present invention.

As shown in Figure 8, the electric vehicle parking facility fire spread prevention and suppression device according to another embodiment of the present invention includes a sensor unit 120, a control unit (not shown), a flame retardant fabric 140, a water barrier 160, and It includes a fire water supply nozzle 180, and this configuration is substantially the same as the configuration previously described with reference to FIG. 1, and the following will focus on the differences.

As shown in FIG. 8(a), the electric vehicle parking facility fire spread prevention and suppression device 100 has a side frame (SF) installed around the vehicle electric charging facility (C), and the inside of this side frame (SF) It includes a flame retardant fabric 140 disposed on.

At this time, when the sensor unit 120 detects a fire in the vehicle (V) being charged in the vehicle electric charging facility (C), it responds to the control signal generated from the control unit, as shown in FIG. 8(b). Accordingly, the flame retardant fabric 140 disposed inside the side frame SF protrudes in the horizontal direction to cover the vehicle V.

That is, a plurality of flame retardant fabrics 140 shown in FIG. 1 are installed inside the frame F installed on the ceiling, and when a fire in the vehicle V is detected, a plurality of flame retardant fabrics (140) are installed in response to a control signal. 140) simultaneously descends in a 90-degree direction to block the inflow of air into the surrounding space on all four sides of the vehicle (V).

However, one flame retardant fabric 140 shown in FIG. 8 is disposed inside the side frame (SF) installed around the vehicle electric charging facility (C). At this time, the flame retardant fabric 140 is formed in a structure in which the bottom surface and one end are open. At this time, when detecting a fire in the vehicle (V), the flame retardant fabric 140 protrudes from the side frame (SF) in the horizontal direction in a dome shape in response to a control signal to cover the front of the vehicle (V), Blocks the inflow of air into the surrounding space of the vehicle (V).

In this way, when the flame retardant cloth 140 protrudes in the horizontal direction to cover the front of the vehicle (V), compared to the case where the flame retardant cloth 140 descends in the vertical direction from the ceiling, the area of the vehicle (V) to be blocked is The surrounding space area can be significantly reduced. Accordingly, fire suppression for the vehicle V can be handled very quickly.
