Electric vehicle battery fire monitoring and suppression system using an elevating drill lance device

[0001] The present invention relates to an electric vehicle battery fire monitoring and suppression system using an elevating drill lance device, and more specifically, to an electric vehicle battery fire monitoring and suppression system using an elevating drill lance device, which can determine in advance the possibility of a fire outbreak by detecting abnormal heating, smoke generation, or flame detection conditions at the bottom of an electric vehicle, and, when a fire occurs, automatically and immediately elevates and closes a drill lance device buried in the ground at the bottom of an electric vehicle to the bottom of the electric vehicle battery to initiate fire suppression, thereby enabling a rapid response to a fire outbreak.

[0002] Recently, as the number of electric vehicles registered in Korea continues to increase, safety measures to respond to electric vehicle fires are emerging as an urgent issue, as fires are frequent and electric vehicle batteries are difficult to extinguish due to their characteristics.

[0003] Electric vehicles have batteries that store high-capacity energy placed at the bottom of the vehicle. If the battery starts to catch fire due to an accident or other reasons, the temperature of the point of combustion is very high, and the high-density integrated form causes continuous heat transfer, which can lead to reignition, making it difficult to extinguish the fire.

[0004] If an electric vehicle catches fire and its battery catches fire, it is difficult to extinguish and easily reignites until completely combusted. This necessitates the continued application of large volumes of firefighting water over a prolonged period of time. The most effective method for suppressing this problem is to lift the burning electric vehicle with a crane and place it in a water tank. However, this method requires lifting the electric vehicle with a crane or other similar device, and the installation (fabrication) of a large tank on-site is therefore highly impractical.

[0005] Currently, the ownership rate of electric vehicles is rapidly increasing, and at the same time, electric vehicle fires are also on the rise. Due to the unique nature of electric vehicle fires, proactive response methods are needed, and technologies that can secure the safety of firefighters and effectively suppress fires to secure the golden time are required.

[0006] The present invention is intended to solve the above-mentioned problems, and to provide an electric vehicle battery fire monitoring and suppression system using an elevating drill lance device that can determine the possibility of a fire in advance by detecting abnormal heating, smoke generation, or flame detection conditions at the bottom of an electric vehicle, and when a fire occurs, automatically and immediately elevates and closes a drill lance device buried in the ground at the bottom of the electric vehicle to the bottom of the electric vehicle battery to begin extinguishing the fire, thereby enabling a rapid response to the fire.

[0013] In one embodiment, a cylinder (331) connected to one side of the lifting lift (320) can be accommodated within the cylinder portion (330).

[0014] In one embodiment, the drill module (340) may include a housing (341) into which fire extinguishing water is injected, an impeller (342) provided within the housing (341) and rotated by the injected water to generate rotational force, a hole cutter (343) connected to the impeller (342) and configured to bore a fire extinguishing hole for injecting water into the electric vehicle battery through the rotational force of the impeller (342) while in close contact with the electric vehicle battery, and an elastic body (344) provided below the hole cutter (343).

[0052] Hereinafter, preferred examples are presented to aid in understanding the present invention. However, the following examples are provided solely to facilitate a better understanding of the present invention, and the scope of the present invention is not limited by the examples.

[0053]

[0054] FIG. 1 is a drawing showing the configuration of an electric vehicle battery fire monitoring and suppression system (1) using an elevating drill lance device according to one embodiment of the present invention.

[0055] Referring to FIG. 1, an electric vehicle battery fire monitoring and suppression system (1) using an elevating drill lance device according to one embodiment of the present invention is largely configured to include a plurality of fire detection means (100), a fire occurrence detection unit (200), and a drill lance device (300) that is buried in the ground of a plurality of electric vehicle parking areas and is lifted to come into close contact with the lower part of the electric vehicle to suppress the fire.

[0056] Fire detection means (100) can be installed in multiple numbers in an electric vehicle parking lot, and can be individually installed at the top of each parking area within the electric vehicle parking lot. Accordingly, in the event of a fire in an electric vehicle within each parking area, each fire detection means (100) is responsible for fire detection in that parking area.

[0057] This fire detection means (100) is installed on the floor of an electric vehicle parking area and can be linked to a camera device (general camera device, thermal imaging camera device, etc.) that collects shooting data by shooting the heating state of the lower part of the electric vehicle, whether a flame has occurred, or whether smoke has occurred.

[0058] In addition, the fire detection means (100) can be connected to a camera device installed on the top of the electric vehicle to collect shooting data by shooting the state of heat generation, whether a flame is generated, or whether smoke is generated on the top of the electric vehicle.

[0059] Additionally, the fire detection means (100) may be a detection sensor installed on the top of the electric vehicle that detects smoke, heat or flames flowing into the top of the electric vehicle and collects detection data.

[0060] In this way, the electric vehicle lower photographing data, upper photographing data, or detection data collected through the fire detection means (100) are provided to the fire occurrence detection unit (200).

[0061]

[0062] The fire occurrence detection unit (200) receives detection data from the fire detection means (100) to identify the location of the fire occurrence, and based on this, it raises and closes the drill module (340) of the drill lance device (300) described later to the bottom of the electric vehicle battery to automatically inject fire extinguishing water to extinguish the fire.

[0063] More specifically, the fire occurrence detection unit (200) receives detection data on the electric vehicle heating status, whether a flame is generated, whether smoke is generated, etc. from the fire detection means (100) installed in each electric vehicle parking area, and based on this, can identify at least one of the abnormal heating status, smoke generation status, and flame detection status of the lower part of the electric vehicle.

[0064] Here, the fire occurrence detection unit (200) does not simply check the heating of the lower battery of the electric vehicle from the moment the electric vehicle is parked, but detects an abnormal heating state after a certain cooling period based on the electric vehicle parking start time. For example, since the lower battery of an electric vehicle is already considerably heated when it is first parked, if an abnormal heating state is detected immediately in this state, it may be misjudged as an abnormal heating state of the electric vehicle. Therefore, the fire occurrence detection unit (200) can detect an abnormal heating state after a certain cooling period (e.g., 10 minutes, etc.) based on the electric vehicle parking start time.

[0065] In one embodiment, the fire occurrence detection unit (200) can determine a shooting spot where abnormal heating occurs easily depending on the type of electric vehicle in the process of detecting an abnormal heating state of a battery at the bottom of an electric vehicle, and can also focus more on shooting the shooting spot.

[0066] For example, since the type of battery applied may be different for each electric vehicle model, the fire occurrence detection unit (200) can learn the point where heat generation is particularly high for each type of parked electric vehicle, and when an electric vehicle of the same type as the vehicle in question is parked later, the abnormal heat generation state can be intensively detected for the point where heat generation is particularly high based on the results learned in advance. In this case, the fire occurrence detection unit (200) can designate the point as a shooting spot so that the point can be more intensively photographed using a dual video camera and a flame detection camera.

[0067] The fire occurrence detection unit (200) determines an abnormality in the electric vehicle based on the collected battery status information, and if it determines that an abnormality such as abnormal heat generation, flames or smoke has occurred, fire suppression can be initiated using the drill lance device (300).

[0068]

[0069] The drill lance device (300) is installed embedded in the ground of multiple electric vehicle parking spaces within an electric vehicle parking lot, and functions to suppress fires by ascending and descending to contact the underside of the electric vehicle. A more detailed description of this is as follows.

[0070] FIG. 2 is a drawing showing the configuration of the drill lance device (300) in more detail, and FIG. 3 is a drawing showing the drill module (340) shown in FIG. 2 in a state where it is raised upward.

[0071] Looking at FIGS. 2 and 3, the drill lance device (300) is configured to include a landfill housing (310), an elevating lift (320), a cylinder part (330), and a drill module (340).

[0072] The embedded housing (310) is installed embedded in a guide groove engraved on the ground of an electric vehicle parking area, and a lifting lift (320) and a drill module (340) are accommodated inside. In addition, a cylinder part (330) is provided on one side of the embedded housing (310). A cylinder (331) connected to the lifting lift (320) on one side is accommodated inside the cylinder part (330).

[0073] Since this landfill housing (310) is installed to have the same height as the ground, there is no interference at all with the bottom of the electric vehicle even when the vehicle is moving.

[0074] On the upper side of the landfill housing (310), an opening / closing door (311) is provided that opens / closes in the left / right directions under the control of the fire detection unit (200) to allow the lifting lift (320) to protrude upward. The opening / closing door (311) is normally kept closed, but under the control of the fire detection unit (200) discussed above, if it is determined that a fire has occurred, it is immediately opened so that the fire at the bottom of the electric vehicle battery can be quickly extinguished.

[0075] The opening door (311) can be made of steel or tempered glass that can sufficiently withstand the load of an electric vehicle. In addition, the opening door (311) is designed to be replaced with a new one from the embedded housing (310) at any time in case of emergency.

[0076] The elevation lift (320) is housed within the built-in housing (310) and its height is adjusted in the vertical direction under the control of the fire detection unit (200) discussed above. This elevation lift (320) is connected to the cylinder rod of the cylinder unit (330).

[0077] The cylinder section (330) houses a cylinder (331) therein, and the cylinder rod at the end of the cylinder (331) is connected to the lifting lift (320) while the cylinder is installed horizontally. The cylinder (331) performs an operation of withdrawing or retracting the cylinder rod under the control of the fire occurrence detection section (200) discussed above, and accordingly, the upper plate of the lifting lift (320) is raised and lowered in the vertical direction.

[0078] The cylinder part (330) is connected to a supply hose for the lift on one side, and serves to protrude and pull out the cylinder rod through water supplied through the supply hose for the lift, thereby allowing the upper plate of the elevator lift (320) to rise upward.

[0079]

[0080] The drill module (340) is installed on a top plate provided on the upper side of the elevator (320), and functions to adhere to the electric vehicle battery, drill a hole in the electric vehicle battery using fire extinguishing fluid, and spray fire extinguishing fluid into the electric vehicle battery through the drilled hole. A more detailed description of this is as follows.

[0081] FIG. 4 is a drawing showing the drill module (340) in more detail, FIG. 5 is a drawing showing the rotary trigger (345), FIG. 6 is a drawing showing the state in which the slide plate (341b), the connecting rod (341c), and the elastic body (341d) within the drill module (340) are connected, and FIG. 7 is a drawing showing the open / closed state of the slide plate (341b).

[0082] Referring to FIGS. 4 to 7, the drill module (340) is installed on the lower side of the upper plate provided on the upper side of the elevator lift (320), and is brought into close contact with the lower side of the electric vehicle battery as its height is adjusted upward by the elevator lift (320) connected to the cylinder (331). A more detailed description of this is as follows.

[0083] The drill module (340) is connected to the upper plate provided on the upper side of the elevator lift (320) and rises and closes to the lower part of the electric vehicle battery.

[0084] In this state, the fire extinguishing water supplied through the fire extinguishing water supply hose connected to one side of the drill module (340) is injected and the drilling of the lower part of the electric vehicle battery begins automatically.

[0085] The drill module (340) is configured to include a housing (341) into which water is injected, an impeller (342) provided within the housing (341) and rotated by water injected through a fire extinguishing water supply hose to generate rotational force, a hole cutter (343) connected to the impeller (342) and drilling a fire extinguishing hole for injecting water into the electric vehicle battery through the rotational force of the impeller (342), and an elastic body (344) provided below the hole cutter (343).

[0086] An impeller (342), a hole cutter (343), and an elastic body (344) are accommodated inside the housing (341). In addition, a water inlet is provided on one side of the housing (341) for injecting fire extinguishing water into the interior, and the impeller (342) inside is rotated by the hydraulic pressure of the fire extinguishing water injected through the water inlet. The rotational force of the impeller (342) is directly transmitted to the hole cutter (343), and as a result, the hole cutter (343) pierces the lower part of the electric vehicle battery by the hydraulic pressure. The fire extinguishing water injected through the water inlet provided in the housing (341) rotates along the inner wall of the housing (341), thereby rotating the impeller (342). The impeller (342) is rotated by the hydraulic pressure to generate rotational force, and the rotational force rotates the hole cutter (343).

[0087] The hole cutter (343) rotates through the rotational force of the impeller (342) and perforates a fire extinguishing hole in the lower part of the electric vehicle battery. Accordingly, a large amount of fire extinguishing water is injected into the electric vehicle battery through the fire extinguishing hole, enabling more effective fire extinguishment.

[0088] At this time, the hole cutter (343) has a hollow pipe shape inside, and a fire extinguishing water discharge port is provided at the end and side to discharge the fire extinguishing water injected through the water injection port into the electric vehicle battery through the perforated fire extinguishing hole.

[0089] The elastic body (344) is compressed when the hole cutter (343) is pressed against the lower part of the electric vehicle battery, and the elastic force causes the housing (341) to always face upward, thereby allowing the hole cutter (343) to always be pressed against the lower part of the electric vehicle battery.

[0090] As the impeller (342) rotates due to water pressure while the hole cutter (343) is in close contact with the lower surface of the electric vehicle battery, the hole cutter (343) rotates, and as a hole is gradually drilled in the electric vehicle battery, the hole cutter (343) penetrates the lower part of the electric vehicle battery. This is possible because the elastic body (344) constantly pushes the housing (341) toward the electric vehicle battery through elastic force.

[0091] Meanwhile, water injected through the water injection port must be discharged to the outside before the hole is drilled by the hole cutter (343). For this purpose, a drain hole (341a) may be formed on the side of the housing (341).

[0092] The drain hole (341a) serves as a kind of water discharge port that allows injected water to be discharged to the outside before the hole is perforated by the hole cutter (343). At this time, after the hole is perforated by the hole cutter (343), a slide plate (341b) is provided on one side of the housing (341) to prevent water injected through the water injection port from being discharged to the outside through the drain hole (341a). This will be examined in more detail as follows.

[0093] Inside the housing (341), a connecting rod (341c) connected to a slide plate (341b) and an elastic body (341d) provided on the connecting rod (341c) are provided, and a rotation trigger (345) that rotates around a central rotation axis to change the open / close state of the slide plate (341b) is provided on the upper plate of the elevator lift (320). Basically, since one side of the slide plate (341b) and the connecting rod (341c) are connected to each other, when the connecting rod (341c) rises, the slide plate (341b) rises and opens the drain hole (341a), and when the connecting rod (341c) moves downward, the slide plate (341b) moves downward and closes the drain hole (341a).

[0094] At this time, the lower end of the connecting rod (341c) is connected to the slide plate (341b), and the upper end is connected to the lower surface of the upper plate connected to the hydraulic cylinder (340). That is, in the present invention, the housing (341) has a structure in which a plurality of bolts are tightly coupled to the lower surface of the upper plate of the elevator lift (320), and the upper end of the connecting rod (341c) has a structure in which a portion thereof passes through the upper plate and is exposed to the outside. A narrow-diameter catching protrusion (341c-1) is formed in the middle of the connecting rod (341c) exposed in this way.

[0095] When the slide plate (341b) is raised upward and the drain hole (341a) is opened, the catch (341c-1) of the connecting rod (341c) is raised upward from the upper plate and exposed. At this time, one side of the rotary trigger (345) is caught on the catch (341c-1), thereby maintaining the current state of the slide plate (341b) (state in which the drain hole (341a) is opened).

[0096] More specifically, the rotation trigger (345) is connected to the upper plate through a rotation axis, thereby rotating clockwise or counterclockwise around the rotation axis at the center.

[0097] At this time, a push transmission part (345a) is provided at one end of the rotary trigger (345). When the hole cutter (343) gradually rises, the push transmission part (345a) comes into contact with the side of the hole cutter (343) and is gradually pushed back. In this case, the rotary trigger (345) is rotated by the rotation axis, and the other end of the rotary trigger (345) is rotated in the opposite direction to the pushing. A catch means (345b) is provided at the other end of the rotary trigger (345) to enable catch engagement with the catch jaw (341c-1) of the connecting rod (341c) described above.

[0098] That is, when the slide plate (341b) rises upward and opens the drain hole (341a), the engaging jaw (341c-1) of the connecting rod (341c) rises above the upper plate and is caught by the engaging means (345b). In this state, as long as the engaging means (345b) is not separated from the engaging jaw (341c-1), the slide plate (341b) maintains the state in which the drain hole (341a) is opened.

[0099] In the current state, an elastic body (341d) is provided on the connecting rod (341c). When the slide plate (341b) is raised upward by the connecting rod (341c), the elastic body (341d) is compressed by the portion connecting the slide plate (341b) and the connecting rod (341c) to each other and the upper plate, thereby generating a compressive force.

[0100] In the current state, when the hole cutter (343) rises, the push transmission unit (345a) that comes into contact with the side of the hole cutter (343) is gradually pushed back. To this end, the side diameter of the hole cutter (343) has a structure in which it gradually widens. Accordingly, when the hole cutter (343) gradually rises, the side diameter also gradually widens, and as a result, the push transmission unit (345a) is gradually pushed back, and accordingly, the rotation trigger (345) itself rotates around the rotation axis.

[0101] By this rotation, the engaging means (345b) is separated from the engaging jaw (341c-1), and as the elastic body (341d) previously compressed by the compressive force pushes the portion connecting the slide plate (341b) and the connecting rod (341c), the slide plate (341b) is lowered, thereby closing the drain hole (341a).

[0102] Accordingly, when the hole cutter (343) completely perforates the lower part of the electric vehicle battery, the slide plate (341b) can block the drain hole (341a) so that the fire extinguishing fluid injected into the housing (341) is not discharged through the drain hole (341a) but is injected into the electric vehicle battery through the fire extinguishing hole.

[0103]

[0104] Next, we will examine the process of fire detection, fire location identification, and fire entry in sequence when a fire occurs through an electric vehicle battery fire monitoring and suppression system (1) using the elevating drill lance device discussed above.

[0105] Figure 8 is a drawing showing the entire process of manually or automatically extinguishing an electric vehicle battery fire using an electric vehicle battery fire monitoring and extinguishing system (1) using an elevating drill lance device in a series of sequential steps.

[0106] Referring to FIG. 8, the electric vehicle battery fire monitoring and suppression system (1) using the elevating drill lance device according to the present invention is designed to enable manual operation through manual operation by a worker, or to detect an electric vehicle fire and automatically suppress the fire through automatic operation.

[0107] First, looking at manual operation, the operator operates a button in a separate junction box (not shown) connected to the drill lance device (300) to open the opening / closing door (311) of the landfill housing (310). In this state, the operation button is operated to open the valve of the supply hose for the lift, thereby supplying water to the cylinder (331) of the cylinder part (330), and accordingly, the cylinder rod of the cylinder part (331) is withdrawn, increasing the height of the lifting lift (320), and the drill module (340) is brought into close contact with the lower part of the electric vehicle battery.

[0108] In this state, the valve of the fire extinguishing water supply hose is opened by operating the operation button to supply fire extinguishing water to the housing (341) of the drill module (340), thereby starting the perforation of the lower part of the electric vehicle battery.

[0109] In the case of autonomous driving, if a fire occurs in an electric vehicle parking lot, the fire is detected by a fire detection device (100) installed in the electric vehicle parking area. The detection data detected by the fire detection device (100) is provided to a fire occurrence identification unit (200), and the fire occurrence identification unit (200) identifies and specifies the exact location of the fire occurrence.
