Description

Technical Field

[0001] The present invention relates to a fire extinguishing device for electric vehicles. Specifically, when a fire occurs in an electric vehicle, not only can the fire of the electric vehicle itself be quickly extinguished in the shortest possible time and the fire spread be prevented, but the fire extinguishing device can also be easily installed with a simpler structure, thereby saving installation costs and shortening time. The fire extinguishing device can be installed in an existing parking area to solve the problem of occupying a large installation space for the fire extinguishing device for electric vehicles. Background Art

[0002] Electric vehicles are vehicles that use electric motors to replace internal fuel engines to generate power, and in most cases use lithium-ion batteries to store energy. Such electric vehicles generally use charging equipment (Charger) available at charging stations or parking lots to charge the batteries, and during the battery charging process, there may be a risk of fire due to battery overheating, electrical shock, overcharging, internal short circuits, poor contact, etc.

[0003] At present, parking lots or charging stations for electric vehicles generally do not have special fire-fighting devices to extinguish fires in the event of a fire in an electric vehicle. Therefore, once a fire occurs in an electric vehicle, there is no direct countermeasure that can be taken. Not only is it easy to burn the charging vehicle, but the fire will also spread to surrounding vehicles, parking lots, and charging equipment, causing damage to life and property. Therefore, it is urgent to formulate relevant safety countermeasures, and various technologies related to extinguishing electric vehicle fires are also being developed.

[0004] For example, Korean Patent Publication No. 10-2022-0130440 (Electric Vehicle Fire Fighting Device) (published on September 27, 2022), Korean Patent Publication No. 10-2023-0123542 (Fire Fighting Water Tank at Electric Vehicle Charging Station) (published on August 24, 2023), etc. disclose a technology of injecting water into a water tank around the electric vehicle to stabilize the battery and extinguish the fire when a fire occurs in the electric vehicle. Korean Registered Patent Publication No. 10-2491008 (Electric Vehicle Fire Fighting Device) (published on January 27, 2023) etc. disclose a technology of using a fire extinguishing cloth covering the electric vehicle to block oxygen to extinguish the fire when a fire occurs in the electric vehicle.

[0005] However, the problems with previous fire fighting devices for electric vehicles are high installation costs, insufficient installation space, and difficulty in quickly controlling the fire and preventing the fire from spreading to the surrounding areas when a fire occurs in the electric vehicle.

[0006] Furthermore, the existing fire fighting devices using water tanks or fire extinguishing cloths need to be installed around the vehicle, and additional construction must be carried out on the existing parking lot, which not only increases the installation cost, but also occupies more installation space than the original parking area. In addition, the existing fire fighting devices using water tanks or fire extinguishing cloths have the problem that fires in electric vehicles caused by abnormal conditions such as batteries will quickly cause thermal runaway, but since temporary walls and water tanks must be set up and water must be refilled inside, it is difficult to achieve the effect of rapid fire fighting in the first place, resulting in the fire spreading to surrounding vehicles, parking lots and charging equipment.

[0007] Therefore, there is a need for a fire extinguishing device for electric vehicles, which, when a fire occurs in the electric vehicle, can not only quickly extinguish the fire of the electric vehicle itself in the shortest time and prevent the fire from spreading, but also can be easily installed with a simpler structure, thereby greatly saving installation costs and time, and can be installed in existing parking areas, solving the problem of occupying a large installation space. Summary of the invention

[0008] The object of the present invention is to solve the above-mentioned problems and provide a fire extinguishing device for electric vehicles, which is equipped with multiple fire extinguishing nozzles for spraying fire extinguishing fluid in the direction of the electric vehicle when a fire occurs while the electric vehicle is being charged, and multiple water curtain forming nozzles for spraying blocking fluid to form a front, back and left and right sides of the electric vehicle. The overall fire extinguishing device can be moved to a parking area or can be simply installed. Therefore, when a fire occurs in the electric vehicle, the fire of the electric vehicle itself can be quickly extinguished in the shortest time, and the fire can be prevented from spreading to surrounding vehicles, parking lots, electric vehicle charging equipment and other parking areas. In addition, with a simpler structure, it does not need to occupy more space, and can also be directly installed in an existing small parking area. It is easy to install without additional construction in the existing parking area, thereby greatly saving the installation cost and time of the fire extinguishing device.

[0037] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that those skilled in the art can easily implement the present invention.

[0038] When describing the embodiments, the description of technical contents that have been widely disclosed in the technical field to which the present invention belongs and are not directly related to the present invention is omitted. The purpose is to avoid blurring the gist of the present invention by omitting unnecessary descriptions and to explain it more clearly.

[0039] For the same reason, in the drawings, some components are exaggerated, omitted or simplified. In addition, the size of each component does not fully reflect the actual size. The same reference numerals are given to the same or corresponding components in each drawing.

[0040] In addition, it can be seen that the expressions and terms used in this article regarding the direction of devices or elements (such as "front", "back", "up", "down", "top", "bottom", "left", "right", "lateral") are only used to simplify the description of the present invention and do not mean that the relevant devices or elements must have a specific direction.

[0041] The present invention will be described below with reference to the accompanying drawings which illustrate a fire extinguishing device 100 for an electric vehicle according to an embodiment of the present invention.

[0042] Figure 1 is a schematic diagram showing a state where a fire extinguishing device for an electric vehicle according to an embodiment of the present invention is arranged in a parking area, Figure 2is a perspective view briefly showing a fire extinguishing device for an electric vehicle according to an embodiment of the present invention, Figure 3 is a front view showing the structure of a fire extinguishing device for an electric vehicle according to an embodiment of the present invention, Figure 4 The diagram is a schematic diagram showing a state where a fire extinguishing device for an electric vehicle according to an embodiment of the present invention is installed in a plurality of adjacent parking areas.

[0043] like Figures 1 to 3 As shown in the figure, a fire extinguishing device 100 for an electric vehicle according to an embodiment of the present invention includes a base 100 , at least one fire sensor 200 , a plurality of fire extinguishing nozzles 300 , and a plurality of water curtain forming nozzles 400 .

[0044] The base 100 constitutes the overall frame of the fire extinguishing device 100 for electric vehicles according to an embodiment of the present invention, is arranged in the parking area 11, and can accommodate the electric vehicle 10 that needs to be parked in the parking area 11 for parking or charging. In the present invention, the parking area 11 refers not only to the so-called parking lot, but also to the parking area 11 in the charging station for charging the electric vehicle 10. In addition, at least one fire sensor 200, a plurality of fire extinguishing nozzles 300, and a plurality of water curtain forming nozzles 400 can be arranged inside and outside the base 100.

[0045] like Figure 2 As shown, the base 100 may include a pair of first bases 110 that are spaced apart from each other and arranged facing each other across the electric vehicle 10. The specific structure of the base 100 will be described later in conjunction with Figure 5 and Figure 6 Detailed description.

[0046] The fire sensor 200 is mounted on the base 100 facing the electric vehicle 10, and can sense whether a fire occurs in the electric vehicle 10 when the electric vehicle 10 is being charged. Figure 3 As shown, the fire sensor 200 may be installed at the lower portion of the electric vehicle 10 , and more precisely, may be installed on the base 100 toward a battery pack (not shown) of the electric vehicle 10 .

[0047] In the present invention, the fire sensor 200 includes not only spark sensors and heat sensors that can sense sparks or heat in the electric vehicle 10, but also a broad concept of various sensing devices such as thermal imaging cameras that obtain thermal images formed by sensing infrared rays emitted from the electric vehicle 10. It is obvious that the type, quantity, and arrangement of such fire sensors can be completely changed by ordinary technicians in this field.

[0048] The fire extinguishing nozzle 300 is mounted on the base 100 and faces the battery pack located at the bottom of the electric vehicle 10. When the fire sensor 200 determines that a fire occurs in the electric vehicle 10, the fire extinguishing fluid W1 can be sprayed in the direction of the electric vehicle 10. Here, the fire extinguishing fluid W1 can be not only common water, but also various fluids (including gas) such as liquid medicines used for fire extinguishing. Figure 2 As shown, a plurality of fire extinguishing nozzles 300 can be installed on the side of the base 100 facing the electric vehicle 10. For this fire extinguishing nozzle 300, it will be described later in conjunction with Figure 5 and Figure 7 Detailed description.

[0049] A plurality of water curtain forming nozzles 400 are installed on the base 100. When a fire occurs in the electric vehicle 10 and the fire extinguishing nozzle 300 sprays the fire extinguishing fluid W1 toward the electric vehicle 10, a water curtain (water wall, water curtain) can be formed to wrap around the electric vehicle 10 in order to prevent the fire occurring in the electric vehicle 10 from spreading to the surrounding area. In this state, common water can be used as the blocking fluid W2.

[0050] Preferably, a plurality of water curtain forming nozzles 400 can be installed on the base 100 adjacent to at least one of the front, back, and left and right sides of the electric vehicle 10, and when a fire occurs in the electric vehicle 10, a blocking fluid W2 is sprayed to form a water curtain covering the front, back, and left and right sides of the electric vehicle 10. Figure 5 , Figure 8 and Fig. 9 Describe in detail.

[0051] In addition, if Figures 1 to 3 As shown in the figure, the fire fighting device 100 for electric vehicles according to an embodiment of the present invention can be directly installed in the parking area 11 corresponding to an electric vehicle in an existing parking lot. Furthermore, the fire fighting device 100 for electric vehicles according to an embodiment of the present invention is manufactured in a finished product form at other places and then moved to the parking area 11 for arrangement. After the base 100 forming the overall frame is first arranged in the parking area 11, at least one fire sensor 200, a plurality of fire fighting nozzles 300 and a plurality of water curtain forming nozzles 400 can be installed inside and outside the base 100.

[0052] Therefore, the fire extinguishing device 100 for electric vehicles according to an embodiment of the present invention is characterized in that it is easy to install and does not require additional construction on the existing parking area 11. Moreover, when one fire extinguishing device 100 is installed, it only occupies a space equivalent to that of one parking area 11. Figure 4The middle figure shows an example in which three fire extinguishing devices 1A, 1B, 1C are provided in three parking areas 11A, 11B, 11C.

[0053] Combine the following Figure 5 and Figure 6 The base 100 constituting the fire extinguishing device 100 for an electric vehicle according to an embodiment of the present invention is described in detail.

It is obvious that a person skilled in the art can arbitrarily change the shape, quantity, layout, etc. of the first fire-extinguishing fluid supply pipe 113 and the first blocking fluid supply pipe 114.

[0063] like Figure 6 As shown in the figure, the heat insulating member 115 can be arranged in the accommodating space 111a to cover the first fire extinguishing fluid supply pipe 113 and the first blocking fluid W2 supply pipe. The heat insulating member 115 can be selected from at least one of the group consisting of mineral wool, glass wool, ceramic wool, biocerak wool, rock wool and ceramic wool.

[0066] like Figure 5As shown, a plurality of fire extinguishing nozzles 300 may be arranged at predetermined intervals along the length direction of a pair of first bases 110 on the inner sides of each pair of first bases 110 toward the battery pack located at the lower portion of the electric vehicle 10 .

[0067] Preferably, if Figure 7 As shown, the plurality of fire extinguishing nozzles 300 may each spray the fire extinguishing fluid W1 in a cone shape toward the battery pack located at the lower portion of the electric vehicle 10 .

[0068] Furthermore, each fire fighting nozzle 300 sprays the fire extinguishing fluid W1 in a cone shape, and the cone-shaped fire extinguishing fluid W1 sprayed from the plurality of fire fighting nozzles 300 overlap, and can extinguish the entire fire-occurring portion of the electric vehicle 10. Here, the cone shape of the fire extinguishing fluid W1 sprayed by the fire fighting nozzle 300 (i.e., the spraying angle θ of the cone shape, the spraying distance) can be adjusted by the pressure, flow rate, etc. of the fire extinguishing fluid W1.

[0069] Figure 5 The figure shows an example in which multiple fire fighting nozzles 300 are arranged along the first base body 111 at the same intervals and facing the same direction, but is not limited to this.
