Description

Technical Field

[0001] This invention relates to an electric vehicle battery fire monitoring and extinguishing system applicable to a mobile robot-type drill gun device. In particular, it relates to a system that can detect the possibility of a fire in advance by identifying abnormal heating, smoke generation, or flame detection status at the bottom of the electric vehicle, and can automatically move the drill gun device configured on one side to the bottom of the electric vehicle and start extinguishing the fire when a fire occurs, thereby quickly responding to the occurrence of a fire. Background Technology

[0002] With the increasing number of electric vehicle registrations in South Korea, there is an urgent need for safety measures to address electric vehicle fire problems such as frequent fires and the difficulty in extinguishing fires due to the characteristics of electric vehicle batteries.

[0003] In electric vehicles, high-capacity energy storage batteries are placed on the underside of the vehicle. When the battery catches fire due to an accident or other reasons, the extremely high temperature of the heat source and the high-density integrated form cause continuous heat transfer and reignition, making it difficult to extinguish the fire.

[0004] When an electric vehicle battery catches fire due to a fire, it is very difficult to extinguish and reignition is likely before the fire is fully burned. Therefore, extinguishing the fire requires a prolonged and continuous injection of large amounts of fire-fighting water. The most effective fire-fighting method to address these problems is to use a crane to lift the burning electric vehicle and place it into a water-filled tank. However, to place the electric vehicle into the tank, a crane must be used to lift it and a large water tank must be installed (fabricated) on-site, making this method practically impossible.

[0005] Currently, with the rapid increase in the ownership of electric vehicles, there is also a growing trend of electric vehicle fires. Due to the unique characteristics of electric vehicle fires, proactive measures are needed, and there is an urgent need for a technology that can ensure the safety of firefighters and preserve the golden rescue time through effective firefighting methods. Summary of the Invention

[0006] The present invention aims to solve the problems mentioned above, and its purpose is to provide an electric vehicle battery fire monitoring and extinguishing system that can detect the possibility of fire in advance by identifying abnormal heating, smoke generation or flame detection status under the electric vehicle, and can automatically move a drill gun device configured on one side to the underside of the electric vehicle and start extinguishing the fire immediately when a fire occurs, thereby quickly responding to the occurrence of fire.

[0007] According to one embodiment of the present invention, an electric vehicle battery fire monitoring and extinguishing system 1 using a mobile robot-type drill gun device may include: a plurality of fire detection components 100 installed in an electric vehicle parking lot; a fire occurrence identification unit 200 that identifies the location of the fire when a fire is detected by the fire detection components 100; a mobile robot-type drill gun device 300 that moves from one side of the electric vehicle parking lot across the electric vehicle parking area in a width direction and extinguishes the fire by moving to the underside of the electric vehicle; and a drill gun control box 400 for storing the mobile robot-type drill gun device 300.

[0008] According to one embodiment of the present invention, the fire detection component 100 can collect at least one of the following detection data: photographing the heating state of the lower part of the electric vehicle, photographing whether flames occur at the lower part of the electric vehicle, photographing whether smoke occurs at the upper part of the electric vehicle, and detecting smoke or hot air flowing into the upper part of the electric vehicle, and provide it to the fire occurrence identification unit 200.

[0009] According to one embodiment of the present invention, the fire occurrence identification unit 200 can determine the fire occurrence location based on the location of the fire detection component 100 that provides the corresponding detection data when the detection data is provided from one of a plurality of fire detection components 100, and move the mobile robot-type drill gun device 300 to the corresponding determined fire occurrence location.

[0010] According to one embodiment of the present invention, the mobile robot-type drill gun device 300 may include: a robot trolley housing 310; moving rollers 320 disposed on the lower part of the robot trolley housing 310; a drive motor 330 that drives the moving rollers 320 to rotate by means of a driving force, thereby causing the robot trolley housing 310 to move to the lower part of the electric vehicle; a position recognition sensor 340 disposed on one side of the robot trolley housing 310, which moves the robot trolley housing 310 to the fire location identified by the fire occurrence recognition unit 200 by recognizing the position; and a drill gun device 350 disposed at the center of the robot trolley housing 310, which is pressed against the lower part of the electric vehicle battery by water pressure and performs drilling and water spraying on the lower part of the electric vehicle battery.

[0011] According to one embodiment of the present invention, the drill gun device 350 moves to the lower part of the electric vehicle in a state of being received inward at the center of the robot trolley housing 310, and can protrude upward toward the upper side of the robot trolley housing 310 by water pressure, thereby fitting tightly against the lower part of the electric vehicle battery.

[0012] According to one embodiment of the present invention, the drill gun device 350 may include: a plurality of hydraulic cylinders 351, which use water supplied by a lifting supply hose to push or retract the plunger in the vertical direction; and a drill module 352, which is mounted on an upper plate provided on the upper side of the hydraulic cylinders 351, is attached to the electric vehicle battery and uses water to drill a hole in the electric vehicle battery, and then uses the hole formed by the drill to spray water into the electric vehicle battery.

[0013] According to one embodiment of the present invention, the drill control box 400 may include: a fire extinguishing water supply hose reel 410; a fire extinguishing water supply hose 420, configured to be wound onto the fire extinguishing water supply hose reel 410, and wound up when the drill tool module 352 moves to supply fire extinguishing water to the drill tool module 352; a fire extinguishing water supply connecting pipe 430, for supplying fire extinguishing water to the fire extinguishing water supply hose 420; and a junction box 440.

[0014] One aspect of this invention is that it can detect the possibility of a fire in advance by identifying abnormal heating, smoke generation, or flame detection status at the bottom of an electric vehicle, and it can also automatically move a drill gun device located on one side to the bottom of the electric vehicle and start extinguishing the fire when a fire occurs, thereby quickly responding to the occurrence of a fire.

[0015] In particular, the present invention has the advantage of being able to drill holes in the lower part of the electric vehicle and inject fire extinguishing water directly into the battery inside in order to effectively extinguish electric vehicle battery fires, thereby quickly extinguishing the fire and preventing reignition.

However, the present invention is not limited to the embodiments disclosed below, but can be implemented in many different forms. These embodiments are provided merely to make the invention more complete and to more fully explain the scope of the invention to those skilled in the art.

Furthermore, unless explicitly stated in the context as plural, plural expressions also include singular meanings. Throughout the specification, when a part is described as including a certain constituent element, unless otherwise expressly stated to the contrary, this does not mean the exclusion of other constituent elements, but rather that other constituent elements may be included.

[0030] Figure 1 This is a schematic diagram illustrating the overall structure of an electric vehicle battery fire monitoring and extinguishing system 1 using a mobile robot-type drill gun device according to an embodiment of the present invention. Figure 2 yes Figure 1 The diagram shows the upper part of an electric vehicle battery fire monitoring and extinguishing system 1 applicable to mobile robot-type drill gun devices.

[0031] See Figure 1 as well as Figure 2 According to one embodiment of the present invention, an electric vehicle battery fire monitoring and extinguishing system 1 using a mobile robot-type drill gun device may generally include: a plurality of fire detection components 100; a fire occurrence identification unit 200; a mobile robot-type drill gun device 300 that moves to the lower part of the electric vehicle and extinguishes the fire; and a drill gun control box 400 for storing the mobile robot-type drill gun device 300.

[0032] Multiple fire detection units 100 can be installed in an electric vehicle parking lot, or individually above each parking area within the parking lot. This allows each fire detection unit 100 to be specifically responsible for detecting the fire in its respective parking area when an electric vehicle fire occurs in that area.

[0033] The fire detection component 100 described above can be linked with a camera device (general camera device and thermal imaging camera device, etc.) that takes pictures and collects data on the heating status, whether flames or smoke are generated under the electric vehicle by installing it on the ground in the electric vehicle parking area.

[0034] In addition, the fire detection component 100 can also be linked with a camera device that is installed on the upper part of the electric vehicle to capture and collect data on the heating status of the upper part of the electric vehicle, whether flames or smoke are generated.

[0035] In addition, the fire detection component 100 can also be a detection sensor that is installed on the upper part of the electric vehicle to detect smoke, heat or flames flowing into the upper part of the electric vehicle and collect detection data.

[0036] The data collected by the fire detection component 100, including the lower part of the electric vehicle, the upper part of the vehicle, or the monitoring data, will be provided to the fire detection unit 200 as described above.

[0037] The fire detection unit 200 can identify the location of a fire by receiving detection data from the fire detection component 100, and based on this, apply a control signal to move the mobile robot drill gun device 300 to the corresponding fire location. After the mobile robot drill gun device 300 moves to the corresponding fire location, it extinguishes the fire by automatically injecting fire extinguishing water.

[0038] More specifically, the fire detection unit 200 can receive detection data related to the heating status of electric vehicles, whether flames occur, and whether smoke occurs from the fire detection components 100 installed in each electric vehicle parking area, and then identify one or more of the abnormal heating status, smoke generation status, and flame detection status of the lower part of the electric vehicle based on this data.

[0039] The fire detection unit 200 does not simply start checking the heat of the battery under the electric vehicle from the moment the electric vehicle stops, but rather starts identifying abnormal heating states after a certain cooling time, based on the time the electric vehicle stops.

[0040] For example, because the battery at the bottom of an electric vehicle is significantly hot immediately after it stops, identifying an abnormal heating state immediately in this state could lead to a misjudgment that the electric vehicle has overheated. Therefore, the fire detection unit 200 can identify an abnormal heating state starting from a point after a certain cooling time (e.g., 10 minutes) based on the time the electric vehicle stops.

[0041] In one embodiment, the fire detection unit 200 can determine the shooting points that are prone to abnormal heating based on the model of the electric vehicle during the process of detecting the abnormal heating state of the battery under the electric vehicle, and shoot the corresponding shooting points more concentratedly.

[0042] For example, since the type of battery used may differ depending on the electric vehicle model, the fire detection unit 200 can learn which locations are particularly prone to overheating based on the electric vehicle model. If an electric vehicle of the same model is parked there in the future, the system can use the learned data to focus on identifying abnormal overheating at these locations. In this scenario, the fire detection unit 200 can designate these locations as shooting points and use a dual-imaging camera and a flame detection camera to capture images more effectively.

[0043] The fire detection unit 200 can determine the abnormal symptoms of the electric vehicle based on the collected battery status information. If abnormal symptoms such as abnormal heating, flames, or smoke are detected, the mobile robot-type drill gun device 300 will start extinguishing the fire.

[0044] The mobile robotic drill bit device 300 moves from one side of the electric vehicle parking lot, traversing the parking area, and can move under the electric vehicles to extinguish fires. This will be described in detail below.

[0045] Figure 3This is a schematic diagram illustrating the mobile robot-type drill gun device 300 in detail. Figure 4 This is a schematic diagram illustrating the general structure of the mobile robot-type drill gun device 300 and the drill gun control box 400.

[0046] See Figure 3 as well as Figure 4 The mobile robot-type drill gun device 300 can generally be composed of a robot trolley shell 310, moving rollers 320, drive motor 330, position recognition sensor 340 and drill gun device 350.

[0047] The robot trolley shell 310 is a compact structure with a low overall height that can be inserted into the lower part of the electric vehicle. The inner side can accommodate the moving rollers 320, the drive motor 330 and the position recognition sensor 340, and the drill gun device 350 can be accommodated inward in the center.

[0048] The movable rollers 320 are located on the lower part of the robot trolley housing 310 and can rotate by the driving force of the drive motor 330. Therefore, by means of the rotation of the movable rollers 320, the robot trolley housing 310 can be quickly moved to the location of the fire.

[0049] The drive motor 330 can drive the moving rollers 320 to rotate by means of driving force, thereby moving the robot trolley housing 310 to the lower part of the electric vehicle. As described above, the drive motor 330 can be configured in a manner corresponding to the number of moving rollers 320. For example, the drive motors 330 can be configured in pairs, one on each side, inside the robot trolley housing 310; in one embodiment, they can also be configured in pairs, one at the front and one at the back, inside the robot trolley housing 310.

[0050] The driving force of the drive motor 330 as described above can be sufficient to move the overall load of the robot trolley shell 310, the drive motor 330, the position recognition sensor 340, and the drill gun device 350.

[0051] In addition, in one embodiment, the drive motor 330 can always receive power via a wired connection by being connected to a separate external power supply cable; in another embodiment, the drive motor 330 can also receive power by being equipped with a separate battery.

[0052] The position recognition sensor 340 can be configured on one side of the robot trolley housing 310, facing the ground. The position recognition sensor 340 can move the robot trolley housing 310 to the fire location identified by the fire occurrence recognition unit 200 by recognizing the position.

[0053] As described above, the location identification sensor 340 can accurately identify the location of a fire by scanning the ground. In some cases, the location identification sensor 340 can accurately identify the location of a fire based on coordinate values.

[0054] Furthermore, in one embodiment, the position recognition sensor 340 can be linked with the drive motor 330. This allows the drive motor 330 to be driven based on the accurate distance to the location of the fire calculated by the position recognition sensor 340, enabling the mobile robot-type drill rig 300 to accurately move to the underside of the burning electric vehicle battery.

[0055] The drill gun assembly 350 moves to the lower part of the electric vehicle in a state of being housed inward at the center of the robot trolley housing 310, and can protrude upward toward the upper part of the robot trolley housing 310 by water pressure, thereby fitting snugly against the lower part of the electric vehicle battery.

[0056] More specifically, the drill gun assembly 350 may include: a plurality of hydraulic cylinders 351 that use water supplied via a lifting supply hose to push or retract the plunger in the vertical direction; and a drill module 352 that is mounted on an upper plate provided on the upper side of the hydraulic cylinders 351, is attached to the electric vehicle battery and uses water to drill a hole in the electric vehicle battery, and then uses the hole formed by the drill to spray water into the electric vehicle battery.

[0057] The hydraulic cylinder 351 can be operated manually or automatically. The hydraulic cylinder 351 uses the water pressure supplied through the lifting hose to push the plunger upwards or retract it downwards, thereby raising or lowering the height of the drill module 352.

[0058] The drilling module 352 is installed on the lower side of the upper plate equipped with the hydraulic cylinder 351. Its height can be adjusted upward by the water pressure of the hydraulic cylinder 351, so that it can be close to the lower part of the electric vehicle battery.

[0059] More specifically, when the drill module 352 initially moves, it is in a state where its height is lowered to the maximum extent by retracting towards the inside of the robot trolley housing 310, and then switches to a state where it can move to the lower part of the electric vehicle as described above.

[0060] Next, with the moving roller 320 rotating under the drive force of the drive motor 330 to successfully move the drill module 352 to the lower part of the electric vehicle battery, the plunger will be pushed out and pressed against the lower part of the electric vehicle battery by means of water supplied through the lifting supply hose.

[0061] In the state described above, drilling will automatically begin on the lower part of the electric vehicle battery while fire extinguishing water is injected through the fire extinguishing water supply hose 420 extending from the drill gun control box 400.

[0062] Figure 5 This is a schematic diagram illustrating the structure of the drill module 352.

[0063] See Figure 5 The drilling module 352 includes: a housing 352-1 for injecting water into it; an impeller 352-2 disposed within the housing 352-1 and rotated by means of water injected through a fire extinguishing water supply hose 420 to generate rotational force; a drilling cutter 352-3 connected to the impeller 352-2 and drilling through the rotational force of the impeller 352-2 to form a fire extinguishing hole for injecting water into the electric vehicle battery; and an elastomer 352-4 disposed at the lower part of the drilling cutter 352-3.

[0064] The impeller 352-2, the drilling tool 352-3, and the elastomer 352-4 are housed inside the outer casing 352-1. Furthermore, a water inlet for injecting fire extinguishing water into the inner part of the outer casing 352-1 is provided on one side, and the impeller 352-2 rotates using the water pressure of the fire extinguishing water injected through the inlet. The rotational force of the impeller 352-2 is directly transmitted to the drilling tool 352-3, which then drills a hole in the lower part of the electric vehicle battery using the water pressure. The water injected through the water inlet on the outer casing 352-1 rotates along the inner wall of the outer casing 352-1, causing the impeller 352-2 to rotate. The impeller 352-2 rotates using the water pressure, generating rotational force, which in turn drives the drilling tool 352-3 to rotate.

[0065] The drill bit 352-3 rotates under the rotational force of the impeller 352-2, thereby drilling a hole in the lower part of the electric vehicle battery to form a fire extinguishing hole. This allows a large amount of water to be injected into the electric vehicle battery through the fire extinguishing hole, thus more effectively extinguishing a fire.

[0066] At this time, the drill bit 352-3 adopts a hollow tubular shape, and is equipped with a fire extinguishing water outlet at the end and side, which allows the fire extinguishing water injected through the water inlet to be discharged into the electric vehicle battery through the fire extinguishing hole formed by the drill.

[0067] The elastomer 352-4 can be compressed when the drill bit 352-3 is pressed against the lower part of the electric vehicle battery, and the elastic force keeps the outer shell 352-1 facing upward, so that the drill bit 352-3 is always pressed against the lower part of the electric vehicle battery.

[0068] With the drill bit 352-3 pressed against the lower surface of the electric vehicle battery, the impeller 352-2 rotates under water pressure, driving the drill bit 352-3 to rotate as well. This gradually forms a hole in the electric vehicle battery, allowing the drill bit 352-3 to penetrate into the lower part of the battery. The principle behind achieving the above-mentioned effect is that the elastic body 352-4 uses elastic force to continuously push the outer casing 352-1 towards the electric vehicle battery.

[0069] In addition, before drilling with the help of the drill bit 352-3, it is necessary to drain the water injected through the water inlet to the outside. For this purpose, a drain hole 352-1a can be formed on the side of the housing 352-1.

[0070] The drain hole 352-1a serves as a drain outlet to expel injected water to the outside before a hole is formed by the drill bit 352-3. To prevent water injected through the water inlet from being discharged to the outside through the drain hole 352-1a after a hole has been formed by the drill bit 352-3, a sliding plate 352-1b is provided on one side of the housing 352-1. This will be explained in detail below.

[0071] Figure 6 This is a schematic diagram illustrating the rotary trigger A. Figure 7 This is a schematic diagram illustrating the connection state of the sliding plate 352-1b, connecting rod 352-1c, and elastic body 352-1d within the drill module 352. Figure 8 This is a schematic diagram illustrating the opening and closing states of the sliding plate 352-1b.

[0072] See Figures 6 to 8 Inside the outer casing 352-1, there is a connecting rod 352-1c connected to the sliding plate 352-1b and an elastic body 352-1d mounted on the connecting rod 352-1c. A rotary trigger A is mounted on the upper plate, rotating about a central axis to change the opening and closing state of the sliding plate 352-1b. Essentially, by connecting one side of the sliding plate 352-1b and the connecting rod 352-1c, when the connecting rod 352-1c moves upward, the sliding plate 352-1b rises accordingly, thereby opening the drain hole 352-1a; conversely, when the connecting rod 352-1c moves downward, the sliding plate 352-1b falls accordingly, thereby closing the drain hole 352-1a.

[0073] At this time, the lower end of the connecting rod 352-1c is connected to the sliding plate 352-1b, while the upper end is connected to the lower surface of the upper plate connected to the hydraulic cylinder 351. That is, the housing 352-1 of the present invention is a structure that is tightly attached to the lower surface of the upper plate connected to the hydraulic cylinder 351 by multiple bolts, while the upper end of the connecting rod 352-1c is equivalent to a structure that passes through the upper plate and is partially exposed to the outside. A small-diameter retaining sill 352-1c' is formed in the middle of the exposed connecting rod 352-1c as described above.

[0074] When the sliding plate 352-1b moves upward and opens the drain hole 352-1a, the locking tab 352-1c' of the connecting rod 352-1c moves upward and is exposed compared to the upper plate. At this time, one side of the rotary trigger A is locked by the corresponding locking tab 352-1c', thereby keeping the sliding plate 352-1b in its current state (the state with the drain hole 352-1a open).

[0075] More specifically, the rotary trigger A is connected to the upper plate via a rotating shaft, thereby rotating clockwise or counterclockwise with the central rotating shaft as a reference.

[0076] At this time, a thrust transmission part A-1 is provided at one end of the rotary trigger A. As the drill bit 352-3 gradually rises, the thrust transmission part A-1 contacts the side of the drill bit 352-3 and gradually retracts. Under the conditions described above, the rotary trigger A will rotate by means of the rotating shaft, and the other end of the rotary trigger A will rotate in the opposite direction to the direction it is pushed. A snap-fit ​​assembly A-2 is provided at the other end of the rotary trigger A, which can snap onto the snap-fit ​​tab 352-1c' of the connecting rod 352-1c as described above.

[0077] That is, when the sliding plate 352-1b moves upward and opens the drain hole 352-1a, the locking tab 352-1c' of the connecting rod 352-1c will rise to the upper side of the upper plate and lock into the locking assembly A-2. In the state described above, unless the locking assembly A-2 separates from the locking tab 352-1c', the sliding plate 352-1b will remain in the state of opening the drain hole 352-1a.

[0078] In the current state, an elastic body 352-1d is provided on the connecting rod 352-1c. When the sliding plate 352-1b moves upward with the help of the connecting rod 352-1c, the elastic body 352-1d is compressed by the part that connects the sliding plate 352-1b and the connecting rod 352-1c and the upper plate, thereby having a compressive force.

[0079] In the current state, as the drill bit 352-3 rises, the thrust transmission part A-1, which contacts the side of the drill bit 352-3, will gradually retract. Therefore, a structure is adopted in which the side diameter of the drill bit 352-3 gradually increases. Thus, as the drill bit 352-3 gradually rises, its side diameter also increases, causing the thrust transmission part A-1 to gradually retract, thereby causing the rotary trigger A to rotate around its rotation axis.

[0080] By means of the rotation as described above, the snap-fit ​​assembly A-2 will separate from the snap-fit ​​retainer 352-1c', and the elastic body 352-1d, which was previously compressed by the compressive force, will push the part that connects the sliding plate 352-1b and the connecting rod 352-1c to each other, thereby causing the sliding plate 352-1b to move in the downward direction and thereby closing the drain hole 352-1a.

[0081] Therefore, when the drill bit 352-3 completely drills through the lower part of the electric vehicle battery, the sliding plate 352-1b will close the drain hole 352-1a. As a result, the fire extinguishing water injected into the outer casing 352-1 will not be discharged through the drain hole 352-1a, but will instead be induced to be injected into the electric vehicle battery through the fire extinguishing hole.

[0082] The drill gun control box 400 is located on one side of the electric vehicle parking lot and serves to store the drill gun device 350. Inside, it houses the fire extinguishing water supply hose reel 410, the fire extinguishing water supply hose 420, the fire extinguishing water supply connecting pipe 430, and the junction box 440.

[0083] A fire extinguishing water supply hose 420 is wound in the fire extinguishing water supply hose reel 410. When the drill module 352 moves, the fire extinguishing water supply hose 420 is wound out at the same time, and the fire extinguishing water is supplied to the outer shell 352-1 of the drill module 352.

[0084] In addition, the drill gun control box 400 is equipped with a pair of opening and closing doors that open to both sides to move the drill tool module 352 that is being stored to the outside. Each opening and closing door can be opened to an angle of more than 120 degrees.

[0085] The preferred embodiments of the present invention have been described above with reference to them. However, those skilled in the art will understand that the present invention can be modified and altered in various ways without departing from the spirit and scope of the invention as set forth in the appended claims.

[0086] Industry availability This invention can detect the possibility of a fire in advance by identifying abnormal heating, smoke generation, or flames at the bottom of an electric vehicle.
