Description

Technology Field

[0001] The present invention relates to a fire spread prevention device for an electric vehicle parking lot, and more specifically, to a fire spread prevention device for an electric vehicle parking lot that can prevent the spread of fire by independently extinguishing individual parking spaces when a fire occurs in a plurality of parking spaces where electric vehicles are parked. Background Technology

[0002] With the recent rapid spread of electric vehicles, concerns regarding fire safety in electric vehicle parking lots are increasing.

[0003] Due to the characteristics of lithium-ion batteries, electric vehicles may exhibit different behaviors compared to conventional internal combustion engine vehicles in the event of a fire; in particular, battery thermal runaway can cause fires to persist for extended periods and pose a high risk of spreading to adjacent vehicles.

[0004] In particular, in the case of electric vehicle parking lots located underground, a method is adopted to suppress fires through the supply of firefighting water and fire detection functions detected by fire detectors installed in the underground parking lot.

[0005] As such, in fire spread prevention systems that collectively control the entire underground parking lot, there is a serious problem in that even if a fire occurs in only a specific parking space, firefighting water is unnecessarily supplied to the entire parking space, leading to a waste of resources and potentially causing water damage to normally parked vehicles.

[0006] To solve these problems, a method is known in which a perimeter cover is installed on a single parking space, raised to form a water tank, and then firefighting water is supplied.

[0007] However, conventional perimeter cover lifting methods for preventing fire spread are structured to handle only a single parking space, which leads to spatial and economic inefficiency in large parking lots where multiple parking spaces are arranged consecutively, as an independent system must be installed for each parking space.

[0008] In addition, conventional perimeter cover lifting methods have the problem that the fixed perimeter structure occupies a significant amount of space even during normal operation, which reduces the space utilization of the parking lot and can act as an obstacle when vehicles enter or exit.

[0009] Accordingly, in the case of a parking lot where multiple parking spaces are arranged continuously in one direction, there is a need for a fire spread prevention device for electric vehicle parking lots that can efficiently manage multiple parking spaces while enabling independent fire response for each individual parking space, minimize space occupation during normal times, and implement a rapid and accurate fire blocking function when necessary.

[0012] In addition, another objective of the present invention is to provide a fire spread prevention device for electric vehicle parking lots that can save space during normal operation and form an effective water tank in the event of a fire through an efficient installation structure utilizing a common partition and a telescopic multi-stage extension mechanism.

[0029] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0030] Before proceeding with the explanation, it should be noted in advance that the technical concept according to the present invention is not limited to fire spread prevention devices for electric vehicle parking lots and can also be applied to fire spread prevention devices for general automobile parking lots.

[0031] In addition, in the various embodiments of the present invention below, components having the same configuration are described using the same reference numerals, and in the other embodiments, configurations different from the one embodiment are described.

[0032] FIGS. 1 to 6 illustrate a fire spread prevention device for an electric vehicle parking lot according to one embodiment of the present invention.

[0033] As illustrated in these drawings, a fire spread prevention device (1) for an electric vehicle parking lot according to one embodiment of the present invention includes a parking base (10), a barrier wall (50), a barrier wall extraction means (60), and a control unit (100).

[0034] A fire spread prevention device (1) for an electric vehicle parking lot according to one embodiment of the present invention has a series of processes from fire detection to deployment of a barrier wall (50) automated, and each component can perform a rapid and effective fire spread prevention function by organically interacting.

[0035] The parking base (10) has a plurality of rectangular parking spaces (20a, 20b, 20c) where electric vehicles are parked, arranged continuously in one direction.

[0036] Multiple parking spaces (20a, 20b, 20c) are arranged continuously in one direction to form a structure that enables efficient parking space utilization and systematic fire response.

[0037] A partition section (30) is provided to partition the parking spaces (20a, 20b, 20c) along the perimeter of each parking space (20a, 20b, 20c) of the parking base (10).

[0038] These compartments (30) form the basis of the overall fire isolation system, enabling independent fire response for each individual parking space (20a, 20b, 20c), while also enabling efficient coordinated response with adjacent parking spaces (20a, 20b, 20c).

[0039] Additionally, the partition section (30) further includes a joint partition section (30ab, 30bc) ​​that simultaneously partitions a pair of mutually adjacent parking spaces (20a, 20b, 20c).

[0040] The common compartment (30ab, 30bc) ​​enables effective fire response between adjacent parking spaces (20a, 20b, 20c) while maximizing the efficiency of the installation space.

[0041] For convenience of explanation, the parking space located on the left side of FIG. 2 is referred to as the first parking space (20a), the parking space adjacent to the first parking space (20a) is referred to as the second parking space (20b), and the parking space adjacent to the second parking space (20b) is referred to as the third parking space (20c). Additionally, the partitioning section that partitions the first parking space (20a) is called the first partitioning section (30a), the partitioning section that partitions the second parking space (20b) is called the second partitioning section (30b), the partitioning section that partitions the third parking space (20c) is called the third partitioning section (30c), the partitioning section that partitions the first parking space (20a) and the second parking space (20b) is called the first joint partitioning section (30ab), and the partitioning section that partitions the second parking space (20b) and the third parking space (20c) is called the second joint partitioning section (30bc).

[0042] Meanwhile, the partition (30) includes a housing (41) and a door (45).

[0043] The housing (41) is embedded to a certain depth along the longitudinal direction of the partition (30) so as not to protrude from the upper surface of the parking base (10), and the interior of the housing (41) forms a space for accommodating a barrier wall (50) and a barrier wall extraction means (60).

[0044] Additionally, an outlet (43) is formed at the top of the housing (41) through which a barrier wall (50) is drawn out from the housing (41).

[0045] It is hinged to the housing (41) of the door (45) to open and close the outlet (43).

[0046] The door (45) can be automatically opened by driving the barrier wall withdrawal means (60), thereby enabling the barrier wall (50) to be deployed. Here, an elastic member (not shown) is provided on the hinge shaft (47) to which the door (45) is hinge-connected, so that the door (45) can be automatically opened by the pressure generated when the barrier wall (50) is withdrawn, and the door (45) can be automatically closed when the barrier wall (50) is received.

[0047] The barrier wall (50) is received in the partition (30) and is withdrawn from the partition (30) to form a water tank on the parking surface (20a, 20b, 20c). The barrier walls (50) forming a single water tank are connected to each other to form a continuous wall surface.

[0048] For convenience of explanation, as shown in FIG. 2, the barrier wall for forming a water tank on the first parking surface (20a) is referred to as the first barrier wall (50a), the barrier wall for forming a water tank on the second parking surface (20b) is referred to as the second barrier wall (50b), and the barrier wall for forming a water tank on the third parking surface (20c) is referred to as the third barrier wall (50c).

[0049] Here, the barrier wall (50) may be made of flame-retardant fabric, which can provide heat resistance capable of withstanding high temperatures in the event of a fire, as well as flexibility. The flame-retardant fabric material may include, for example, silicone-coated glass fiber fabric, aramid fiber, or ceramic fiber, but is not limited thereto.

[0050] Additionally, the barrier wall (50) has a foldable structure, and in a standby state before the barrier wall (50) is withdrawn from the partition (30), the barrier wall (50) can be folded and received in the partition (30), and in a withdrawal state when the barrier wall (50) is withdrawn from the partition (30), it can be unfolded and withdrawn. The folding method of the barrier wall may include, for example, an accordion method, a zigzag method, or a rolling method, but is not limited thereto.

[0051] Meanwhile, one end of the barrier wall (50) can be supported by the free end of the rod (61) of the barrier wall extraction means (60) to be described later, and the other end of the barrier wall (50) can be supported by the cylinder body (65). Through this dual-end support structure, the barrier wall (50) can be stably deployed and maintained, and structural strength capable of withstanding the pressure of firefighting water can be secured.

[0052] The barrier wall extraction means (60) supports the barrier wall (50) and is received in the partition (30) to extract the barrier wall (50).

[0053] In one embodiment of the present invention, the barrier extraction means (60) comprises a rod (61) that extends and contracts in length in stages and is formed in multiple stages, and a cylinder body (65) that telescopically accommodates the rod (61) and extends the rod (61) in multiple stages by means of fluid provided from an external pipe (70).

[0054] The rod (61) has a telescopic structure, for example, a structure that is pulled out in multiple stages.

[0055] The diameter of each stage of the rod (61) has a size that decreases in stages, and the stepwise decrease in diameter of the rod (61) can provide sufficient structural strength while ensuring smooth sliding between each stage.

[0056] The three-stage rod (61) illustrated in this embodiment includes a first rod (61a) located at the top, a second rod (61b) and a third rod (61c) whose diameters gradually increase.

[0057] Here, although the present embodiment is illustrated as having a structure in which the rod is withdrawn in three stages, the rod may have a structure in which it is withdrawn in two or four or more stages.

[0058] The cylinder body (65) can telescopically accommodate the rod (61) and includes a chamber in which fluid is contained.

[0059] The inner diameter of the cylinder body (65) has a size larger than the maximum diameter of the rod (61).

[0060] The cylinder body (65) is connected to an external pipe (70), and the working fluid supplied from the external pipe (70) to the cylinder body (65) may be water or compressed air and may be selected according to the requirements of the firefighting system.

[0061] Independent pressure chambers may be formed inside the cylinder body (65) for each stage, thereby enabling stepwise load extension.

[0062] For example, for the first stage of extension of the rod (61), a pressure of 4 bar may be required, for example, for the second stage of extension of the rod (61), a pressure of 5 bar, for example, and a pressure of 6 bar, for example, for the third stage of extension of the rod (61) may be applied sequentially, but are not limited thereto. In addition, the extension of each stage may be monitored by a pressure sensor, and the extension height of the rod (61) may be precisely controlled by measuring the pressure inside the cylinder body (65) in real time.

[0063] Accordingly, the withdrawal height of the barrier wall (50) can be controlled according to the extension of each stage of the load (61).

[0064] The control unit (100) analyzes temperature information and fire spread speed from the fire detector (200) to determine the optimal height of the barrier wall (50), and can control the extension of the rod (61) so that, for example, in the case of an initial fire (temperature 60-100℃), it extends in one stage (600mm), in the case of an intermediate fire (temperature 100-200℃), it extends in two stages (900mm) as shown in FIG. 5, and in the case of a large fire (temperature 200℃ or higher), it extends in three stages (1500mm) as shown in FIG. 4.

[0065] Meanwhile, multiple barrier wall extraction means (60) can be independently connected to an external pipe (70) for each barrier wall extraction means (60) corresponding to a single parking space (20a, 20b, 20c), thereby enabling selective control for each individual parking space (20a, 20b, 20c).

[0066] For example, a plurality of barrier wall extraction means (60) corresponding to the first parking surface (20a) is connected by a first external pipe (70a), a plurality of barrier wall extraction means (60) corresponding to the second parking surface (20b) is connected by a second external pipe (70b), and a plurality of barrier wall extraction means (60) corresponding to the third parking surface (20c) is connected by a third external pipe (70c).

[0067] However, as illustrated in FIG. 2, the barrier wall extraction means (60) located in the first common section (30ab) and simultaneously supporting the first barrier wall (50a) and the second barrier wall (50b) is connected to the first external pipe (70a) and the second external pipe (70b). Likewise, the barrier wall extraction means (60) located in the second common section (30bc) ​​and simultaneously supporting the second barrier wall (50b) and the third barrier wall (50c) is connected to the second external pipe (70b) and the third external pipe (70c).

[0068] Meanwhile, a plurality of barrier wall extraction means (60) disposed in a common partition (30ab, 30bc) ​​in a fire spread prevention device (1) for an electric vehicle parking lot according to one embodiment of the present invention can simultaneously support a pair of barrier walls corresponding to each of the adjacent parking surfaces. That is, a single barrier wall extraction means (60) has a structure in which it simultaneously supports a pair of barrier walls that block each of the adjacent pair of parking surfaces.

[0069] As an example, as illustrated in FIGS. 2 and 6, if a fire is detected in the first parking space (20a) among the adjacent first parking space (20a) and second parking space (20b), the first barrier wall (50a) and the second barrier wall (50b) can be deployed simultaneously in the first common compartment (30ab). This can provide a preventive effect of blocking the spread of fire in advance, and is particularly effective when considering the possibility of rapid spread in the case of electric vehicle fires.

[0070] In addition, a fire spread prevention device (1) for an electric vehicle parking lot according to one embodiment of the present invention may include an external pipe (70) and a control valve (80) for controlling the flow of fluid flowing through the external pipe (70), as a fluid supply system for supplying an operating fluid to a barrier wall extraction means (60).

[0071] The fluid supply system may include a pressure control function and may adjust the supply pressure according to the intensity of the fire or the height of the deployment of the barrier wall (50). For example, when responding to an initial fire, the barrier wall (50) may be partially deployed at a low pressure by receiving a signal from the control unit (100), and when the fire spreads, the barrier wall (50) may be fully deployed at a high pressure.

[0072] Here, the control valve (80) may include a solenoid valve, a ball valve, or a butterfly valve.

[0073] When the control unit (100) receives a fire detection signal from any one of the fire detectors (200) that detect heat, temperature, or smoke of each of the plurality of parking spaces (20a, 20b, 20c), it analyzes the signal and controls the barrier wall withdrawal means (60) to drive the barrier wall (50a, 50b, 50c) so that the barrier wall of the corresponding parking space (20a, 20b, 20c) is withdrawn. The control unit (100) may include, for example, a microprocessor, memory, an input / output interface, a communication module, etc., and can monitor and respond to the fire situation in real time.

[0074] Additionally, the control unit (100) may analyze the intensity or spread of the fire and adjust the deployment height of the barrier wall (50). For example, in the case of an initial fire, the rod (61) of the barrier wall withdrawal means (60) may be extended only one or two stages, and in the case of fire spreading, the rod (61) may be extended to the maximum height.

[0075] With this configuration, for example, if a fire occurs in the first parking space (20a) adjacent to the second parking space (20b), when the control unit (100) receives a fire detection signal from the fire detector (200) of the first parking space (20a), the control unit (100) controls the control valves (80) provided in the first external pipe (70a) to open, thereby simultaneously supplying fluid to the barrier wall extraction means (60) corresponding to the first parking space (20a) through the first external pipe (70a).

[0076] Accordingly, the rod (61) of each barrier wall extraction means (60) extends in length and opens the door (45) and is extracted from the partitions (30a, 30ab), so that the first barrier wall (50a) rises to a maximum height as shown in FIG. 6 and forms a water tank of a certain depth along the perimeter of the first parking surface (20a). At this time, the second barrier wall (50b) located in the first common partition (30ab) also rises together with the first barrier wall (50a).

[0077] And, at the same time as a water tank is formed in the first parking space (20a) through the first barrier wall (50a), firefighting water is continuously sprayed through a sprinkler nozzle (210) located above the first parking space (20a) to suppress the fire of the electric vehicle parked in the first parking space (20a) and collect in the water tank formed in the first parking space (20a), thereby preventing the fire that occurred in the first parking space (20a) from spreading to the second parking space (20b) and adjacent areas.

[0078] Accordingly, when a fire occurs in a plurality of consecutively arranged parking spaces (20a, 20b, 20c), individual parking spaces (20a, 20b, 20c) can be independently controlled to enable independent fire response, thereby preventing the spread of fire and simultaneously securing space efficiency and installation cost-effectiveness, and reducing unnecessary energy consumption in parking spaces (20a, 20b, 20c) where no fire has occurred.

[0079] In addition, the fire spread prevention device (1) for an electric vehicle parking lot according to one embodiment of the present invention further includes an inclined plate (90) provided on one side of the parking base (10) for parking and exiting the parking base (10).

[0080] The ramp plate (90) can perform the function of connecting the height difference between the ground and the parking base (10), and enables the smooth entry and exit of the electric vehicle.

[0081] The surface of the inclined plate (90) may be treated with anti-slip treatment, such as a non-slip coating, groove processing, or the installation of an anti-slip mat.

[0082] Additionally, drainage facilities such as side drains and drainage holes may be applied to the inclined plate (90), thereby preventing rainwater or car wash water from flowing into the parking base (10).

[0083] Here, the unexplained reference numeral 220 is a fire water pipe that supplies fire water to the sprinkler nozzle (210).

[0084] Meanwhile, in FIGS. 7 and 8, a fire spread prevention device for an electric vehicle parking lot according to another embodiment of the present invention, unlike the previously described embodiment, a plurality of barrier wall extraction means (60) disposed in a common partition (30ab, 30bc) ​​individually support the barrier walls (50a, 50b, 50c) of the corresponding parking spaces (20a, 20b, 20c) and are arranged crosswise along the common partition (30ab, 30bc).

[0085] For example, as illustrated in FIG. 7, in the first common section (30ab), a barrier wall extraction means (60) corresponding to the first parking surface (20a) and a plurality of barrier wall extraction means (60) corresponding to the second parking surface (20b) are arranged intersectingly along the first common section (30ab). Likewise, in the second common section (30bc), a barrier wall extraction means (60) corresponding to the second parking surface (20b) and a plurality of barrier wall extraction means (60) corresponding to the third parking surface (20c) are arranged intersectingly along the second common section (30bc).

[0086] Thus, each common section (30ab, 30bc) ​​is provided with an independent barrier withdrawal means (60) for each parking space (20a, 20b, 20c), while also enabling efficient utilization of the space of the common section (30ab, 30bc).

[0087] For example, if a fire occurs in the first parking space (20a), the control unit (100) controls the control valves (80) provided in the first external pipe (70a) to open, thereby simultaneously supplying fluid through the first external pipe (70a) to the barrier extraction means (60) corresponding to the first parking space (20a).

[0088] Accordingly, the rod (61) of each barrier wall extraction means (60) extends in length and opens the door (45) and is extracted from the partitions (30a, 30ab), so that the barrier wall (50a) rises to a maximum height as shown in FIG. 8 and forms a water tank of a certain depth along the perimeter of the first parking surface (20a). At this time, the second barrier wall (50b) located in the first common partition (30ab) does not rise together.

[0089] And, at the same time as a water tank is formed in the first parking space (20a) through the first barrier wall (50a), firefighting water is continuously sprayed through a nozzle located above the first parking space (20a) to suppress the fire of the electric vehicle parked in the first parking space (20a) and collect in the water tank formed in the first parking space (20a), thereby preventing the fire that occurred in the first parking space (20a) from spreading to the second parking space (20b) and adjacent areas.

[0090] Here, although not illustrated, as another embodiment of the fire spread prevention device for an electric vehicle parking lot according to the present invention, the barrier wall withdrawal means may be disposed in each of the four corner areas of the partition for each parking space, and the barrier wall may be withdrawn to form the parking space into a rectangular tank.

[0091] Thus, according to the present invention, when a fire occurs in a plurality of parking spaces arranged continuously, individual parking spaces can be independently extinguished to enable independent fire response, thereby preventing the spread of fire, simultaneously securing space efficiency and installation cost-effectiveness, and reducing unnecessary energy consumption in parking spaces where no fire has occurred.

[0092] In addition, through an efficient installation structure utilizing a shared compartment and a telescopic multi-stage extension mechanism, it is possible to save space during normal operation and form an effective water tank in case of fire.

[0093] Meanwhile, in the aforementioned embodiments, the fire spread prevention device for an electric vehicle parking lot according to the present invention is illustrated as having a parking base provided at a certain height from the ground, but is not limited thereto, and the parking base is provided on the ground, in which case the barrier wall and the barrier wall extraction means may be installed embedded in the ground.
