Description

Technology Field

[0001] The present invention relates to a parking container installed in a parking lot to store and park vehicles, and in particular to a parking container system equipped with a fire suppression function. Background Technology

[0002] Recently, as the use of electric vehicles (EVs) has been steadily increasing, controversy regarding the risks of EV fires is also growing. The level of risk varies depending on the type of battery installed in the vehicle; however, lithium iron phosphate (LFP) batteries are relatively safe because their chemically stable structure prevents explosive combustion and primarily generates heat.

[0003] However, in the case of NCM (ternary) lithium-ion batteries, which are installed in most electric vehicles and aim for high performance and long driving range, if a certain critical point is exceeded, they cause thermal runaway, in which combustion occurs at an explosive speed until the energy is depleted and the temperature instantly rises to over 1,000°C.

[0004] To prepare for fire, electric vehicle battery packs are collections of thousands of cells, each separated by partitions and independently packaged, so even if a part ignites, it takes time for the flames to spread to the entire pack.

[0005] However, in the case of a fire triggered by damage caused by external forces such as traffic accidents rather than a fire caused by errors such as overcharging, there is a high possibility that these bulkheads will also be damaged, so there are limitations to the protective capacity of the bulkheads.

[0006] Furthermore, because electric vehicle batteries are structurally located directly beneath the seats, they inevitably have a fatal impact on passenger safety in the event of a fire; additionally, since batteries are sensitive to fire and react violently, passengers must escape within a very short period of time.

[0007] Furthermore, fire suppression in electric vehicles is significantly more difficult than in internal combustion engine vehicles, and flammable gases harmful to the human body are generated during the fire. While fires in internal combustion engine vehicles can be extinguished within a short time by spraying water and fire extinguishing agents, fires in electric vehicles require much more time to extinguish even with such methods, making it inefficient.

[0008] Meanwhile, although electric vehicle chargers are mostly installed in underground parking lots of apartment buildings or other structures unaffected by external weather conditions, making charging convenient, there is a risk that the fire could spread to the apartment building or structure in the event of a fire. Furthermore, since ventilation is poor underground, toxic gases cannot escape, raising concerns about increased casualties.

[0009] Accordingly, the inventors have conducted research on a parking container technology that allows vehicles to be stored and parked in a parking lot, and which enables efficient fire suppression even if a fire occurs inside or outside the parking container by linking with an existing fire hydrant system or sprinkler system, thereby minimizing the spread of fire.

[0027] On the other hand, when it is stated that one component is "directly connected" or "directly coupled" to another component, it should be understood that no other component exists in between.

[0028] FIG. 1 is a diagram illustrating the configuration of an embodiment of a parking container system equipped with a fire suppression function according to the present invention. As shown in FIG. 1, the parking container system (100) equipped with a fire suppression function according to this embodiment is linked with an existing fire hydrant system or sprinkler system (200) and includes a parking container (110), a camera (120), a network hub (130), a control unit (140), a door driving unit (150), a branch pipe (160), an opening / closing valve (170) for the branch pipe, an upper nozzle (180), and a lower nozzle (190).

[0029] At least one parking container (110) is installed in a parking lot to store and park a vehicle, and at least one of the front or rear is equipped with an openable screen door (111). At this time, the screen door (111) may be implemented to open and close by sliding from top to bottom, or may be implemented to open and close by sliding from bottom to top.

[0030] Meanwhile, the screen door (111) may be implemented in the form of a waterproof fabric made of a waterproof material and may be implemented to be folded in a folding manner or rolled up in a rolling manner, but is not limited thereto.

[0031] Meanwhile, the upper surface, lower surface, both sides, and rear surface of the parking container (110) may each be assembled by connecting unit plates (110a) of a certain size to an intermediate connecting frame (110b) with screws (110c), and the unit plates (110a), intermediate connecting frame (110b), screws (110c), and screen door (111) may be made of a metal material that is resistant to heat, but is not limited thereto.

[0032] FIG. 2 is an external view illustrating an embodiment of a parking container of a parking container system equipped with a fire suppression function according to the present invention, and FIG. 3 is a drawing illustrating an embodiment of a parking container coupling structure of a parking container system equipped with a fire suppression function according to the present invention. As shown in FIG. 3, unit plates (110a) of a certain size are coupled by screws (110c) through a coupling frame (110b), so that a prefabricated parking container (110) as shown in FIG. 2 can be seen to be realized.

[0033] At least one camera (120) is installed in the parking lot and captures video of the parking lot interior in real time. At this time, the camera (120) may be a CCTV camera or an IP camera, and if the parking lot is very large, it may be installed in each parking area and may be installed in a direction facing the parking space of each parking area.

[0034] The network hub (130) connects the camera (120) to the network. At this time, the network hub (130) may be a wireless network hub that supports wireless networks such as WiFi, Bluetooth, Zigbee, etc., or a wired network hub that supports wired networks such as Ethernet.

[0035] The control unit (140) receives real-time video of the parking lot interior captured by the camera (120) through the network hub (130), analyzes the real-time video of the parking lot interior to detect a fire in real time, and generates a fire response signal when a fire is detected. The fire response signal generated by the control unit (140) can be transmitted to the door drive unit (150), the opening and closing valve (170) for branch piping, the pump of the fire hydrant system or sprinkler system, and the pre-action valve, which will be described later.

[0036] The door drive unit (150) drives the opening and closing of a screen door (111) mounted on at least one of the front or rear of a parking container (110), and closes the screen door (111) upon receiving a fire response signal generated from the control unit (140). For example, although not shown in the drawing, the door drive unit (150) may include a motor that provides rotational driving force and a power conversion means such as a gear or rope that converts the rotational force from the motor into vertical reciprocating force and applies it to the screen door (111).

[0037] At this time, as illustrated in FIG. 2, the door drive unit (150) can be implemented to completely close at least one of the front or rear of the parking container (110) by sliding the screen door (111), which is mounted on at least one of the front or rear of the parking container, from the top to the bottom of the container.

[0038] Alternatively, as illustrated in FIG. 4, the door drive unit (150) may be implemented to partially close at least one of the front or rear of the parking container (110) by sliding the screen door (111), which is mounted on at least one of the front or rear of the parking container, from the bottom to the top to a specific height.

[0039] FIG. 4 is a drawing illustrating an embodiment of a screen door opening and closing structure of a parking container system equipped with a fire suppression function according to the present invention, and can be seen that a screen door (111) mounted on at least one of the front or rear of a parking container (110) slides from the bottom to the top to a specific height, partially closing at least one of the front or rear of the parking container (110).

[0040] At this time, the parking container (110) may be implemented without an upper surface, and the two sides may be formed only up to a specific height so that water can be filled from the bottom to the top.

[0041] The branch pipe (160) branches and transports water pumped by a pump of the fire hydrant system or sprinkler system (200). At this time, the branch pipe (160) can be implemented such that one end is connected to the primary main pipe or secondary main pipe of the fire hydrant system or sprinkler system (200) described later, and the other end is connected to the upper nozzle (180) installed on the upper side of the parking container and the lower nozzle (190) installed on the lower side of the parking container, respectively.

[0042] The branch pipe opening / closing valve (170) is installed in the branch pipe (160) and opens upon receiving a fire response signal generated from the control unit (140). At this time, the branch pipe opening / closing valve (170) may be implemented in the form of an electronic check valve that allows water to flow only in the direction of the upper nozzle (180) installed on the upper side of the parking container (110) and the lower nozzle (190) installed on the lower side of the parking container (110), but is not limited thereto.

[0043] At least one upper nozzle (180) is installed on the upper inner side of the parking container (110), and water branched by the branch pipe (160) is sprayed on the upper inner side of the parking container (110) where the screen door (111) is closed.

[0044] At least one lower nozzle (190) is installed in the lower inner side of the parking container (110), and water branched by the branch pipe (160) is sprayed in the lower inner side of the parking container (110) where the screen door (111) is closed.

[0045] The fire suppression operation of the parking container system (100) equipped with a fire suppression function implemented in this manner is described. When the video of the parking lot interior captured in real time by the camera (120) is received by the control unit (140) through the network hub (130), the control unit (140) analyzes the video of the parking lot interior to detect a fire in real time and generates a fire response signal when a fire is detected.

[0046] A fire response signal generated by the control unit (140) is transmitted to the door drive unit (150), and the screen door (111) mounted on at least one of the front or rear of the parking container (110) is closed by the door drive unit (150). Additionally, a fire response signal generated by the control unit (140) is transmitted to the branch pipe opening / closing valve (170), and the branch pipe opening / closing valve (170) is opened.

[0047] Meanwhile, a fire response signal generated by the control unit (140) is transmitted to the pump and pre-action valve of the fire hydrant system or sprinkler system (200), and the pump and pre-action valve are driven. Water pumped by the pump is retained in a state filled in the primary side of the pre-action valve, and when the pressure on the secondary side of the pre-action valve becomes lower than that on the primary side due to the opening of the branch pipe shut-off valve (170), water is transferred to the secondary side of the pre-action valve.

[0048] At the same time, water is transferred through the branch pipe (160) to the upper nozzle (180) installed on the upper inner side of the parking container (110) and the lower nozzle (190) installed on the lower inner side of the parking container (110), respectively, so that water is sprayed simultaneously from the upper and lower inner sides of the parking container (110) and filled into the parking container (110) with the screen door (111) closed.

[0049] Accordingly, when a fire occurs inside the parking lot outside the parking container (110), the spread of fire to the electric vehicle parked inside the parking container (110) is prevented, and when a fire occurs inside the parking container (110), the fire in the electric vehicle parked inside the parking container (110) with the screen door (111) closed is efficiently suppressed.

[0050] By implementing it in this way, the present invention enables a vehicle to be stored and parked in a parking container installed in a parking lot, and by linking it with an existing fire hydrant system or sprinkler system, efficient fire suppression is possible even if a fire occurs inside or outside the parking container, thereby minimizing the spread of fire, so that even if a fire occurs in the parking lot, damage to life and property can be minimized.

[0051] Meanwhile, according to an additional aspect of the present invention, a parking container system (100) equipped with a fire suppression function may further include an internal fire detector (192). At least one internal fire detector (192) is installed inside the parking container (110) to detect a fire inside the parking container (110). For example, the internal fire detector (192) may be implemented to detect a fire by detecting temperature, gas, or heat, but is not limited thereto.

[0052] The signal detected by the internal fire detector (192) is transmitted to the control unit (140) through the receiving panel of the fire hydrant system or sprinkler system. At this time, the control unit (140) can be implemented to generate a fire response signal when a fire is detected by the internal fire detector (192).

[0053] A fire response signal generated by the control unit (140) is transmitted to the door drive unit (150), and the screen door (111) mounted on at least one of the front or rear of the parking container (110) is closed by the door drive unit (150). Additionally, a fire response signal generated by the control unit (140) is transmitted to the branch pipe opening / closing valve (170), and the branch pipe opening / closing valve (170) is opened.

[0054] Meanwhile, a fire response signal generated by the control unit (140) is transmitted to the pump and pre-action valve of the fire hydrant system or sprinkler system (200), and the pump and pre-action valve are driven, and the water pumped by the pump is retained in a state filled in the primary side of the pre-action valve, and then the water is transferred to the secondary side of the pre-action valve.

[0055] At the same time, water is transferred through the branch pipe (160) to the upper nozzle (180) installed on the upper inner side of the parking container (110) and the lower nozzle (190) installed on the lower inner side of the parking container (110), respectively, so that water is sprayed simultaneously from the upper and lower inner sides of the parking container (110) and filled into the parking container (110) with the screen door (111) closed.

[0056] Accordingly, when a fire occurs inside the parking lot outside the parking container (110), the spread of fire to the electric vehicle parked inside the parking container (110) is prevented, and when a fire occurs inside the parking container (110), the fire in the electric vehicle parked inside the parking container (110) with the screen door (111) closed is efficiently suppressed.

[0057] Meanwhile, according to an additional aspect of the present invention, a parking container system (100) equipped with a fire suppression function may further include a fire hydrant system or a sprinkler system (200). The fire hydrant system or sprinkler system (200) may include a fire extinguishing water tank (210), a pump (220), a pre-action valve (230), a primary side main pipe (240), a secondary side main pipe (250), and a pressure chamber (260).

[0058] The fire extinguishing tank (210) stores water. At this time, the fire extinguishing tank (210) may be installed underground or on a rooftop, and it is desirable that it be earthquake-resistant. In addition, the fire extinguishing tank (210) may be constructed integrally with or separately from a water supply tank that stores various types of domestic water.

[0059] The pump (220) is driven upon receiving a fire response signal to pump water in the fire extinguishing tank (210). At this time, it is preferable that the pump (220) be operated by receiving power from a main power source, but be implemented to receive power from an auxiliary power source in the event of a failure of the main power source.

[0060] The pre-action valve (230) holds water pumped by the pump (220) in a state filled in the primary side and is actuated upon receiving a fire response signal to transfer the water held in the primary side to the secondary side.

[0061] The primary side main pipe (240) is connected between the pump (220) and the primary side of the pre-action valve (230) to transfer water pumped from the pump (220) to the primary side of the pre-action valve. At this time, at least one valve for opening and closing the primary side pipe may be installed on the primary side main pipe (240).

[0062] The secondary side main pipe (250) is connected between the secondary side of the pre-action valve (230) and a fire hydrant or sprinkler, and transfers water transferred to the secondary side of the pre-action valve (230) to the fire hydrant or sprinkler. At this time, at least one valve for opening and closing the secondary side pipe may be installed on the secondary side main pipe (250).

[0063] The pressure chamber (260) maintains the pressure of the primary side main pipe (240) at a constant level. The pressure chamber (260) maintains the pressure of the primary side main pipe (240) at a constant level to prevent the pre-action valve (230) from malfunctioning due to a decrease in the primary side pressure of the pre-action valve (230) caused by leakage, etc.

[0064] When looking at the operation of the fire hydrant system or sprinkler system (200) implemented in this way, the pump (220) is first driven and the primary main pipe (240) is filled with water, and the pressure of the primary main pipe (240) is maintained at a constant level by the pressure chamber (260).

[0065] In this state, if a fire occurs, the pre-action valve (230) operates to transfer water held in the primary side to the secondary side. At the same time, the pump (220) operates to pump water stored in the water tank (210) and transfer it to the primary side main pipe (240), and the water transferred to the primary side main pipe (240) is transferred to the secondary side main pipe (250) by the pre-action valve (230) and transferred to a fire hydrant or sprinkler through the secondary side main pipe (250).

[0066] At the same time, the opening / closing valve (170) for the branch pipe, which is installed on the branch pipe (160) branched from the primary main pipe (240) or the secondary main pipe (250), is opened, and water is transferred through the branch pipe (160) to the upper nozzle (180) installed on the upper side of the parking container (110) and the lower nozzle (190) installed on the lower side of the parking container (110), respectively, and water is sprayed simultaneously from the upper and lower surfaces inside the parking container (110) and filled into the parking container (110) with the screen door (111) closed.

[0067] Accordingly, when a fire occurs inside the parking lot outside the parking container (110), the spread of fire to the electric vehicle parked inside the parking container (110) is prevented, and when a fire occurs inside the parking container (110), the fire in the electric vehicle parked inside the parking container (110) with the screen door (111) closed is efficiently suppressed.

[0068] As described above, the present invention enables a vehicle to be stored and parked in a parking container installed in a parking lot, and by linking with an existing fire hydrant system or sprinkler system, efficient fire suppression is possible even if a fire occurs inside or outside the parking container, thereby minimizing the spread of fire, so that even if a fire occurs in the parking lot, damage to life and property can be minimized.
