Description

Electric vehicle battery fire suppression device equipped with a mobile robotic drill lance combined with an automated transport vehicle

[0001] The present invention relates to an electric vehicle battery fire suppression device incorporating a mobile robot-type drill lance device combined with an automated transport vehicle. More specifically, the invention relates to an electric vehicle battery fire suppression device incorporating a mobile robot-type drill lance device combined with an automated transport vehicle that enables rapid response to a fire by automatically moving to the location of the fire via remote operation when a fire occurs in the lower part of the electric vehicle, and then automatically and immediately moving a drill lance device housed inside to the lower part of the electric vehicle via a mobile robot to initiate fire suppression.

[0002] Recently, as the number of registered electric vehicles in Korea continues to increase, the need to establish safety measures to address electric vehicle fires is emerging as an urgent issue, as fires occur frequently and are difficult to extinguish due to the characteristics of electric vehicle batteries.

[0003] Electric vehicles place high-capacity energy-storing batteries at the bottom of the vehicle. If a fire starts in the battery due to an accident or other various reasons, fire suppression is difficult because the temperature of the heat source is very high and continuous heat transfer occurs due to the high-density concentration, leading to re-ignition.

[0004] When a fire occurs in an electric vehicle and ignites the battery, it is difficult to put out and easily reignites until it is completely burned, making it difficult to extinguish without continuously pouring large amounts of water over a long period. The most effective method to resolve this is to lift the burning electric vehicle with a crane and place it into a water-filled tank; however, this method is practically very difficult because it requires lifting the vehicle using a crane and installing (or fabricating) a large tank on-site.

[0005] Currently, as electric vehicle ownership is rapidly increasing, the number of electric vehicle fires is also on the rise. Due to the unique characteristics of electric vehicle fires, proactive response measures are required, and there is a need for technology that can ensure the safety of firefighters and secure the golden time through effective fire suppression.

[0006] The present invention aims to solve the aforementioned problems by providing an electric vehicle battery fire suppression device that utilizes a mobile robot-type drill lance device combined with an automated transport vehicle, which enables rapid response to a fire by automatically moving to the location of the fire via remote operation when a fire occurs in the lower part of the electric vehicle, and then automatically and immediately moving a drill lance device housed inside to the lower part of the electric vehicle via a mobile robot to initiate fire suppression.

[0007] An electric vehicle battery fire suppression device (100) equipped with a mobile robot-type drill lance device combined with an automatic transport vehicle according to one embodiment of the present invention may include an automatic transport vehicle (110) that waits on one side of an electric vehicle parking lot and moves to the location of the fire occurrence through remote operation of a manager terminal when an electric vehicle fire occurs, a fire extinguishing water tank (120) mounted on the automatic transport vehicle, a fire extinguishing water pump (130) connected to the fire extinguishing water tank (120), a mobile robot-type drill lance device (140) stored in the automatic transport vehicle (110) and pulled out from the automatic transport vehicle (110) to move to the underside of the electric vehicle to suppress the fire, and a fire extinguishing water supply hose (150) that connects the fire extinguishing water pump (130) and the mobile robot-type drill lance device (140) to each other and is unwound when the mobile robot-type drill lance device (140) moves while in a wound state.

[0008] According to one embodiment of the present invention, the automated transport vehicle (110) can be moved to the location where the fire occurred through any one of the AGV (Automated Guided Vehicle) method, AMR (Autonomous Mobile Robots) method, or remote control method.

[0009] According to one embodiment of the present invention, the automatic transport vehicle (110) may include a communication module (111) that receives a remote signal for automatic movement to automatically move to the location where the fire occurred from the manager terminal or receives a remote operation signal for remote operation from the manager terminal, a camera device (112) that captures the surroundings and transmits the captured image to the manager terminal in real time through the communication module (111), and a sensor device (113) that scans the surroundings and transmits scan data to the manager terminal in real time through the communication module (111).

[0010] According to one embodiment of the present invention, the mobile robot-type drill lance device (140) may include a robot trolley housing (141), a moving wheel (142) positioned at the bottom of the robot trolley housing (141), a driving motor (143) that rotates the moving wheel (142) based on driving force to move the robot trolley housing (141) to the bottom of the electric vehicle, a position recognition sensor (144) positioned on one side of the robot trolley housing (141) and detects the position so that the robot trolley housing (141) can be positioned at the bottom of the electric vehicle, and a drill lance device (145) positioned at the center of the robot trolley housing (141) and closes to the bottom of the electric vehicle battery through water pressure to perform drilling and water spraying at the bottom of the electric vehicle battery.

[0011] According to one embodiment of the present invention, the drill lance device (145) is moved to the lower part of the electric vehicle while being received inwardly from the center of the robot trolley housing (141), and can protrude upward from the robot trolley housing (141) so as to be in close contact with the lower part of the electric vehicle battery through hydraulic pressure.

[0012] The drill lance device (145) according to one embodiment of the present invention may include a plurality of hydraulic cylinders (145-1) that extend or retract a plunger in an up-and-down direction through water supplied through a supply hose for a lift, and a drill module (145-2) that is installed on an upper plate provided on the upper side of the hydraulic cylinders (145-1), is in close contact with the electric vehicle battery to drill a hole in the electric vehicle battery through water, and sprays water into the electric vehicle battery through the drilled hole.

[0013] According to one embodiment of the present invention, the fire extinguishing water pump (130) and the mobile robot-type drill lance device (140) may be driven by receiving power from a battery mounted within the automatic transport vehicle (110), or by receiving power from a separate battery mounted separately on the automatic transport vehicle (110).

[0014] According to one aspect of the present invention, when a fire occurs in the lower part of an electric vehicle, the device automatically moves to the location of the fire through remote operation, and then automatically moves a drill lance device housed inside to the lower part of the electric vehicle via a mobile robot to initiate fire suppression, thereby having the advantage of being able to respond quickly to the fire.

[0015] In particular, according to the present invention, an automatic transport vehicle is equipped with a fire extinguishing water tank, a fire extinguishing water pump, a mobile robot-type drill lance device, etc., thereby providing the advantage of being able to quickly suppress electric vehicle fires regardless of location, even in places where separate fire extinguishing facilities are not provided.

[0016] In addition, according to the present invention, by using an automated transport vehicle, it is possible to enter as close as possible to narrow spaces where large fire trucks have difficulty entering, thereby having the advantage of being able to quickly perform initial suppression.

[0017] In addition, according to the present invention, in order to effectively suppress an electric vehicle battery fire, the lower part of the electric vehicle is perforated and fire extinguishing water is directly injected into the internal battery, thereby providing the advantage of rapid extinguishing and preventing re-ignition.

[0055]

[0056] FIG. 1 is a drawing showing the overall configuration of an electric vehicle battery fire suppression device (100) that applies a mobile robot-type drill lance device combined with an automatic transport vehicle according to one embodiment of the present invention.

[0057] Referring to FIG. 1, an electric vehicle battery fire suppression device (100) equipped with a mobile robot-type drill lance device combined with an automatic transport vehicle according to one embodiment of the present invention may be largely composed of an automatic transport vehicle (110), a fire extinguishing water tank (120), a fire extinguishing water pump (130), a mobile robot-type drill lance device (140), and a fire extinguishing water supply hose (150).

[0058] The automatic transport vehicle (110) may refer to a means of transportation that waits at one side of the electric vehicle parking lot and can move to the location of the fire through remote operation of a manager terminal in the event of an electric vehicle fire. A more detailed examination of this is as follows.

[0059] FIG. 2 is a diagram showing the process of an automatic transport vehicle (110) moving to a fire location via remote operation.

[0060] Looking at FIG. 2, the automatic transport vehicle (110) may be equipped with a fire extinguishing water tank (120), a fire extinguishing water pump (130), a mobile robot-type drill lance device (140), and a fire extinguishing water supply hose (150). In the event of a fire in an electric vehicle, the vehicle may be moved to the location of the fire through remote operation of a manager terminal located at a remote location, so that the fire extinguishing water tank (120), the fire extinguishing water pump (130), the mobile robot-type drill lance device (140), and the fire extinguishing water supply hose (150) can be positioned as close as possible to the electric vehicle.

[0061] To this end, the automatic transport vehicle (110) may include a communication module (111) that receives a remote signal for automatic movement to automatically move to the location where a fire occurred from a manager terminal or receives a remote operation signal for remote operation from a manager terminal, a camera device (112) that captures the surroundings and transmits the captured image to the manager terminal in real time through the communication module (111), and a sensor device (113) that scans the surroundings and transmits the scan data to the manager terminal in real time through the communication module (111).

[0062] In one embodiment, the automated transport vehicle (110) can be moved to the location of the fire through any one of the following methods: an AGV (Automated Guided Vehicle) method, an AMR (Autonomous Mobile Robots) method, or a remote control method.

[0063] For example, when the AGV method is applied to an automated transport vehicle (110), markings to indicate the path may be provided in advance on the floor of the parking lot passageway using magnetic tape or paint lines of a specific color. Additionally, a unique identification number, such as a serial number, may be assigned to each parking space.

[0064] In this case, if a fire occurs, the automatic transport vehicle (110) scans the magnetic tape or paint line through the sensor device (113) and automatically moves along a fixed path, and after recognizing the serial number assigned to each parking space, it can automatically move along the path to the corresponding parking space.

[0065] In another example, when the AMR method is applied to an automatic transport vehicle (110), the automatic transport vehicle (110) recognizes the serial number of the parking space where a fire occurred through the sensor device (113), and then, when an obstacle appears while moving to the parking space using the camera device (112) and the sensor device (113), it can autonomously search for an optimal alternative path and move to the corresponding parking space in an autonomous driving manner accordingly.

[0066] In another example, if a remote control method is applied to the automatic transport vehicle (110), the automatic transport vehicle (110) transmits the video captured in real time through the camera device (112) to the manager terminal in real time so that the surroundings can be monitored in real time, and the manager can move the automatic transport vehicle (110) to the location of the fire by directly controlling it remotely through the manager terminal or the central control room monitor through the sensor device (113).

[0067]

[0068] The fire extinguishing water tank (120) is mounted on the automatic transport vehicle (110) and can store a large amount of fire extinguishing water to be sprayed onto an electric vehicle that has caught fire. At this time, the fire extinguishing water tank (120) can be connected to a fire extinguishing water pump (130). Meanwhile, the fire extinguishing water in the fire extinguishing water tank (120) can be loaded at a maximum capacity within a range that does not exceed the permissible load capacity of the automatic transport vehicle (110).

[0069]

[0070] The fire extinguishing water pump (130) is connected to the fire extinguishing water tank (120) and can generate sufficient water pressure to discharge the fire extinguishing water stored in the fire extinguishing water tank (120) in the direction of the mobile robot-type drill lance device (140) described later, and can perform the function of discharging the fire extinguishing water in the direction of the mobile robot-type drill lance device (140) with the generated water pressure.

[0071] At this time, the fire extinguishing water pump (130) may be equipped with an electric motor and may be driven by receiving power from a vehicle battery that is mounted on the automatic transport vehicle (110), or by receiving power from a separate battery that is mounted on the automatic transport vehicle (110).

[0072] Additionally, in one embodiment, the fire water pump (130) may be exposed to the outside or stored in a storage box that can be opened and closed from the outside for ease of maintenance. In this case, the fire water pump (130) may be stored with dustproof and waterproof treatment to prevent electric shock accidents caused by the fire water.

[0073]

[0074] A fire water supply hose (150) may be connected to the fire water pump (130), and a mobile robot-type drill lance device (140) may be connected to the end of the fire water supply hose (150).

[0075] At this time, the fire extinguishing water supply hose (150) is stored in a wound state on the automatic transport vehicle (110), and can be extended in length as it is automatically unwound when the mobile robot-type drill lance device (140) moves from the fire source toward the electric vehicle.

[0076] The fire extinguishing water supply hose (150) serves to supply fire extinguishing water supplied through the fire extinguishing water pump (130) to the mobile robot-type drill lance device (140), and can be automatically wound up and organized when the fire is extinguished and the mobile robot-type drill lance device (140) is received back into the automatic transport vehicle (110).

[0077]

[0078] The mobile robot-type drill lance device (140) is stored in the automatic transport vehicle (110), and when the automatic transport vehicle (110) arrives at a location adjacent to the fire occurrence site, it can be withdrawn from the automatic transport vehicle (110) and moved to the underside of the electric vehicle to proceed with fire suppression. This is described in more detail as follows.

[0079] FIG. 3 is a drawing showing the mobile robot-type drill lance device (140) in more detail, and FIG. 4 is a drawing showing the process of the mobile robot-type drill lance device (140) moving to the lower part of an electric vehicle in the state of FIG. 2.

[0080] Looking at FIGS. 3 and 4, the mobile robot-type drill lance device (140) can be largely composed of a robot trolley housing (141), a moving wheel (142), a driving motor (143), a position recognition sensor (144), and a drill lance device (145).

[0081] The robot trolley housing (141) is a compact structure with a low overall height that can enter the lower part of the electric vehicle, and can accommodate a moving wheel (142), a driving motor (143), and a position recognition sensor (144) on the inside, and can accommodate a drill lance device (145) in the center in the inward direction.

[0082] The moving wheel (142) is positioned at the bottom of the robot trolley housing (141) and can be rotated based on the driving force of the drive motor (143). Thus, the robot trolley housing (141) can be quickly moved to the fire location by the rotation of the moving wheel (142).

[0083] The drive motor (143) can rotate the moving wheel (142) based on driving force to move the robot trolley housing (141) to the bottom of the electric vehicle. Such drive motors (143) may be arranged to correspond to the number of moving wheels (142). For example, the drive motors (143) may be arranged in pairs, one on the left and one on the right, within the robot trolley housing (141), or in one embodiment, one on the front and one on the back within the robot trolley housing (141).

[0084] The driving force of such a drive motor (143) can have a force sufficient to move the entire load of the robot trolley housing (141), the drive motor (143), the position recognition sensor (144), and the drill lance device (145).

[0085] Additionally, in one embodiment, the drive motor (143) may be driven by receiving power from a vehicle battery mounted on the automatic transport vehicle (110), or by receiving power from a separate battery mounted separately on the automatic transport vehicle (110). Alternatively, the drive motor (143) may be driven by receiving power from a separate battery mounted separately on the mobile robot-type drill lance device (140).

[0086] The position recognition sensor (144) can be positioned on one side of the robot trolley housing (141) so as to face the ground. The position recognition sensor (144) can serve to determine the position so that the robot trolley housing (141) can be accurately positioned at the location where the fire occurred.

[0087] This location recognition sensor (144) can scan the ground to accurately determine the location of the fire, and in some cases, the location recognition sensor (144) can accurately determine the location of the fire based on coordinate values.

[0088] Additionally, in one embodiment, the position recognition sensor (144) may be coupled with the drive motor (143). Through this, the position recognition sensor (144) calculates the exact distance to the location where the fire occurred, and then drives the drive motor (143) based on this, thereby allowing the mobile robot-type drill lance device (140) to be accurately positioned at the bottom of the electric vehicle battery where the fire occurred.

[0089] The drill lance device (145) is moved to the lower part of the electric vehicle while being received inwardly from the center of the robot trolley housing (141), and can protrude upward from the robot trolley housing (141) so as to be in close contact with the lower part of the electric vehicle battery through hydraulic pressure.

[0090] More specifically, the drill lance device (145) may include a plurality of hydraulic cylinders (145-1) that extend or retract a plunger in an up-and-down direction through water supplied through a supply hose for a lift, and a drill module (145-2) that is installed on a top plate provided above the hydraulic cylinders (145-1), is in close contact with the electric vehicle battery to drill a hole in the electric vehicle battery through water, and sprays water into the electric vehicle battery through the drilled hole.

[0091] The hydraulic cylinder (145-1) functions to raise or lower the height of the drill module (145-2) by pulling the plunger upward or retracting it by the water pressure of the fire extinguishing water supplied through the lift supply hose.

[0092] The drill module (145-2) is installed on the lower side of the upper plate provided in the hydraulic cylinder (145-1), and is in close contact with the lower part of the electric vehicle battery as its height is adjusted upward through the hydraulic pressure of the hydraulic cylinder (145-1).

[0093] More specifically, the drill module (145-2) is retracted into the inner direction of the robot trolley housing (141) during the initial movement, so that its height is lowered to the maximum extent, and in this state, it is prepared to move to the lower part of the electric vehicle.

[0094] Subsequently, as the moving wheel (142) rotates by the driving force of the drive motor (143), the drill module (145-2) is moved to the bottom of the electric vehicle battery, and the plunger is withdrawn through the fire extinguishing water supplied through the lift supply hose, thereby adhering to the bottom of the electric vehicle battery.

[0095] In this state, as fire extinguishing water supplied through the fire extinguishing water supply hose (150) is injected, the lower part of the electric vehicle battery is automatically started to be perforated.

[0096]

[0097] FIG. 5 is a drawing showing the structure of the drill module (145-2) in more detail.

[0098] Referring to FIG. 5, the drill module (145-2) is configured to include a housing (145-2a) into which fire extinguishing water is injected, an impeller (145-2b) provided within the housing (145-2a) and which generates rotational force by rotating through water injected via a fire extinguishing water supply hose (420), a hole cutter (145-2c) connected to the impeller (145-2b) and which drills a fire extinguishing hole for injecting water into the electric vehicle battery through the rotational force of the impeller (145-2b), and an elastic body (145-2d) provided below the hole cutter (145-2c).

[0099] An impeller (145-2b), a hole cutter (145-2c), and an elastic body (145-2d) are housed inside the housing (145-2a). Additionally, a fire extinguishing water inlet is provided on one side of the housing (145-2a) for injecting fire extinguishing water into the interior, and the impeller (145-2b) inside rotates due to the water pressure of the fire extinguishing water injected through the inlet. The rotational force of the impeller (145-2b) is transmitted directly to the hole cutter (145-2c), and as a result, the hole cutter (145-2c) penetrates the lower part of the electric vehicle battery due to the water pressure. The fire extinguishing water injected through the inlet provided in the housing (145-2a) rotates along the inner wall of the housing (145-2a), and at this time, the impeller (145-2b) rotates. The impeller (145-2b) rotates by water pressure to generate rotational force, and through this rotational force, the hole cutter (145-2c) is rotated.

[0100] The hole cutter (145-2c) rotates through the rotational force of the impeller (145-2b) and drills a fire extinguishing hole in the lower part of the electric vehicle battery. Therefore, a large amount of fire extinguishing water is injected into the electric vehicle battery through the fire extinguishing hole, allowing the fire to be extinguished more effectively.

[0101] At this time, the hole cutter (145-2c) has a hollow pipe shape, and a fire extinguishing water discharge port is provided at the end and side so that fire extinguishing water injected through the fire extinguishing water injection port is discharged into the electric vehicle battery through the perforated fire extinguishing hole.

[0102] The elastic body (145-2d) is compressed when the hole cutter (145-2c) is in close contact with the bottom of the electric vehicle battery, and by using elastic force to ensure that the housing (145-2a) always faces upward, the hole cutter (145-2c) can always be in close contact with the bottom of the electric vehicle battery.

[0103] With the hole cutter (145-2c) in close contact with the lower surface of the electric vehicle battery, the impeller (145-2b) rotates due to water pressure, causing the hole cutter (145-2c) to rotate and gradually drill a hole in the electric vehicle battery, thereby causing the hole cutter (145-2c) to penetrate the lower surface of the electric vehicle battery. This is made possible because the elastic body (145-2d) pushes the housing (145-2a) toward the electric vehicle battery at all times through elastic force.

[0104] Meanwhile, until a hole is perforated by the hole cutter (145-2c), the fire extinguishing water injected through the fire extinguishing water inlet must be discharged to the outside, and for this purpose, a drain hole may be formed on the side of the housing (145-2a).

[0105] The drain hole serves as a type of fire extinguishing water outlet that allows the injected fire extinguishing water to be discharged to the outside before the hole is perforated by the hole cutter (145-2c). At this time, after the hole is perforated by the hole cutter (145-2c), a slide plate is provided on one side of the housing (145-2a) to prevent the water injected through the fire extinguishing water inlet from being discharged to the outside through the drain hole. This is described in more detail as follows.

[0106]

[0107] FIG. 6 is a drawing showing a rotary trigger (A), FIG. 7 is a drawing showing the state in which a slide plate, a connecting rod, and an elastic body are connected within a drill module (145-2), and FIG. 8 is a drawing showing the open / closed state of the slide plate.

[0108] Referring to FIGS. 6 to 8, a connecting rod connected to a slide plate and an elastic body provided on the connecting rod are provided inside the housing (145-2a), and a rotary trigger (A) is provided on the top plate to change the open / closed state of the slide plate by rotating around a central axis of rotation. Basically, as one side of the slide plate and the connecting rod are connected to each other, when the connecting rod goes up, the slide plate goes up and opens the drain hole, and when the connecting rod goes down, the slide plate goes down and closes the drain hole.

[0109] At this time, the lower end of the connecting rod is connected to the slide plate, and the upper end is connected to the lower surface of the top plate connected to the hydraulic cylinder (145-1). That is, in the present invention, the housing (145-2a) is structured to be tightly coupled to the lower surface of the top plate connected to the hydraulic cylinder (145-1) with a plurality of bolts, and the upper end of the connecting rod passes through the top plate and is partially exposed to the outside. A narrow-diameter stopper is formed in the middle of the exposed connecting rod.

[0110] When the slide plate is raised upward to open the drain hole, the locking projection of the connecting rod rises above the top plate and is exposed. At this time, one side of the rotating trigger (A) engages with the locking projection, thereby maintaining the current state of the slide plate (the state with the drain hole open).

[0111] More specifically, the rotation trigger (A) is connected to the top plate through a rotation axis, so that it rotates clockwise or counterclockwise with respect to the rotation axis at the center.

[0112] At this time, a sliding transmission part (A-1) is provided at one end of the rotary trigger (A). When the hole cutter (145-2c) gradually rises, the sliding transmission part (A-1) comes into contact with the side of the hole cutter (145-2c) and is gradually pushed backward. In this case, the rotary trigger (A) rotates by the rotation axis, and the other end of the rotary trigger (A) rotates in the opposite direction of the pushing. A locking means (A-2) is provided at the other end of the rotary trigger (A) to enable a locking connection with the locking projection of the connecting rod described earlier.

[0113] That is, when the slide plate is raised upward and the drain hole is opened, the locking projection of the connecting rod rises above the top plate and gets caught on the locking means (A-2). In this state, unless the locking means (A-2) is separated from the locking projection, the slide plate maintains the state of having the drain hole opened.

[0114] In the current state, an elastic body is provided in the connecting rod, and when the slide plate moves upward by the connecting rod, the elastic body acquires compressive force as it is compressed by the part connecting the slide plate and the connecting rod and the top plate.

[0115] In the current state, when the hole cutter (145-2c) rises, the sliding transmission part (A-1) that comes into contact with the side of the hole cutter (145-2c) is gradually pushed backward. To this end, the side diameter of the hole cutter (145-2c) has a structure that gradually widens. Therefore, as the side diameter also gradually widens when the hole cutter (145-2c) rises, the sliding transmission part (A-1) is gradually pushed backward, and accordingly, the rotation trigger (A) itself rotates around the rotation axis.

[0116] Due to this rotation, the locking means (A-2) is separated from the locking jaw, and as the elastic body that was previously compressed by the compressive force pushes the part connecting the slide plate and the connecting rod, the slide plate moves downward, and accordingly, the drain hole is closed.

[0117] Therefore, when the hole cutter (145-2c) completely pierces the bottom of the electric vehicle battery, the slide plate blocks the drain hole, so that the fire extinguishing water injected into the housing (145-2a) is not discharged through the drain hole but is instead injected into the electric vehicle battery through the fire extinguishing hole.
