Description

Electric bus fire suppression device

[0001] The present invention relates to an electric bus fire suppression device, and more specifically, to an electric bus fire suppression device that is easy to transport via a vehicle through a foldable structure, and that can quickly extinguish a fire by hydraulically piercing a battery placed on the upper part of an electric bus while in close contact with the electric bus where a fire has occurred and injecting fire extinguishing water.

[0002] Recently, the number of registered electric vehicles in Korea has been steadily increasing, and major public transportation such as taxis and buses are also changing to electric vehicles. However, 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] In particular, in the case of electric buses, batteries storing high-capacity energy are placed on the top of the bus, and if the battery starts to catch fire due to an accident or other various reasons, the temperature of the point of combustion is very high, and continuous heat transfer occurs due to the densely packed form, which can lead to reignition, making it difficult to extinguish the fire.

[0004] If the battery of an electric bus catches fire, it is difficult to extinguish and can easily reignite until it is completely burned, making it difficult to extinguish the fire by continuously pouring in a large amount of firefighting water for a long time.

[0005] The most effective fire suppression method to solve this problem is to lift the burning electric vehicle with a crane and place it in a water tank to suppress it, but this method is difficult to apply to electric buses due to their weight and size.

[0006] The present invention is intended to solve the aforementioned problems, and to provide an electric bus fire suppression device that is easy to transport via a vehicle through a foldable structure, and that can quickly extinguish a fire by hydraulically piercing a battery placed on the upper part of an electric bus while in close contact with the electric bus where a fire has occurred and injecting fire extinguishing water.

[0007] An electric bus fire suppression device (100) according to one embodiment of the present invention includes a fire extinguishing tank (110) provided on a transport vehicle, a folding frame (120) that is opened or closed by hydraulic pressure, and a fire extinguishing lance (130) that is disposed on the folding frame (120) and sprays fire extinguishing water supplied from the fire extinguishing tank (110) into the inside of the battery after piercing a battery disposed on the upper part of the electric bus, and the fire extinguishing lance (130) is positioned adjacent to the side of the electric bus in an unfolded state, and in a state where the folding frame (120) is fixed to the side of the electric bus, the fire extinguishing lance (130) pierces the battery disposed on the upper part of the electric bus by hydraulic pressure and then sprays fire extinguishing water into the inside of the battery to extinguish a fire.

[0008] According to one embodiment of the present invention, the folding frame (120) comprises: a lower frame (121), an upper frame (122) connected by a hinge so that one side of the lower frame (121) can rotate; a folding cylinder (123) connected between the lower frame (121) and the upper frame (122) to control the rotation of the upper frame (122) through hydraulic pressure; an upper fixed frame (124) connected by a hinge so that one side of the upper frame (122) can rotate and is in close contact with the upper surface of the electric bus; an upper fixed cylinder (125) connected between the upper frame (122) and the upper fixed frame (124) to control the rotation of the upper fixed frame (124) through hydraulic pressure; a lower fixed frame (126) connected by a hinge so that one side of the lower frame (121) can rotate and is in close contact with the lower surface of the electric bus; a folding cylinder (123) connected between the lower frame (121) and the lower fixed frame (126) to control the rotation of the upper fixed frame (124) through hydraulic pressure. It may include a lower fixed cylinder (127) that controls the rotation of the lower fixed frame (126) and a perforation cylinder (128) that is positioned at the end of the upper fixed frame (124) and pushes the extinguishing water injection lance (130) located on the upper part of the electric bus toward the battery.

[0009] The folding frame (120) according to one embodiment of the present invention is formed so that its height can be adjusted up and down while connected to the side of the lower frame (121), and may further include a mounting portion (129) that is mounted on the transport vehicle through a hook-and-loop connection on one side.

[0010] According to one embodiment of the present invention, the mounting portion (129) may include a mounting hook means (129-1) having a ring shape that is mounted on the transport vehicle, and a mounting cylinder (129-2) that is connected between the lower frame (121) and the mounting hook means (129-1) and adjusts the vertical height of the mounting hook means (129-1) through hydraulic pressure.

[0011] According to one embodiment of the present invention, the folding cylinder (123), the upper fixing cylinder (125), the lower fixing cylinder (127), the perforation cylinder (128) and the mounting cylinder (129-2) are connected to a hydraulic pump (200) disposed on one side of the transport vehicle through a hydraulic supply line and can be controlled hydraulically.

[0012] According to one embodiment of the present invention, the folding cylinder (123), the upper fixed cylinder (125), the lower fixed cylinder (127), the perforation cylinder (128), and the mounting cylinder (129-2) can each be independently controlled by the hydraulic pressure supplied from the hydraulic pump (200).

[0013] According to one embodiment of the present invention, the fire extinguishing water injection lance (130) is connected to a fire extinguishing water pump (300) disposed on one side of the fire extinguishing water tank (110) through a fire extinguishing water supply line to receive fire extinguishing water.

[0014] The fire extinguishing lance (130) according to one embodiment of the present invention includes a lance head (131) that pierces the upper part of the battery through hydraulic pressure and a fire extinguishing nozzle (132) that is formed on the side of the fire extinguishing lance (130) body and sprays the fire extinguishing water outward, and the lance head (131) can be connected in a replaceable form from the fire extinguishing lance (130) body.

[0015] According to one embodiment of the present invention, the body of the extinguishing water injection lance (130) is formed in multiple stages, and the extinguishing water nozzle (132) can be respectively arranged in each stage.

[0016] According to the present invention, there is an advantage in that a fire can be quickly extinguished by hydraulically piercing a battery placed on the upper part of an electric bus in close contact with the electric bus where a fire has occurred and injecting fire extinguishing water.

[0017] In addition, according to the present invention, the volume can be minimized during storage and transportation through the folding structure, and it has the advantage of being able to be easily and conveniently transported to a fire scene by being mounted on the rear of a transport vehicle (e.g., truck, etc.).

[0018] In addition, according to the present invention, since it is firmly fixed in close contact with the upper and lower surfaces of the electric bus, the lance for spraying fire extinguishing water does not fall out or become separated during the process of spraying high-pressure fire extinguishing water into the battery by piercing the battery through hydraulic pressure, thereby having the advantage of being able to stably extinguish a fire.

[0055]

[0056] FIG. 1 is a drawing schematically showing the overall configuration of an electric bus fire suppression device (100) according to one embodiment of the present invention, and FIG. 2 is a drawing showing a state in which the electric bus fire suppression device (100) illustrated in FIG. 1 is mounted on a transport vehicle.

[0057] Looking at FIGS. 1 and 2, an electric bus fire suppression device (100) according to one embodiment of the present invention may largely include a fire extinguishing tank (110), a folding frame (120), and a fire extinguishing lance (130).

[0058] The fire extinguishing tank (110) is a tank that stores fire extinguishing water to extinguish a fire that has occurred in the battery of an electric bus. It is not limited by storage capacity and can be loaded onto a transport vehicle (e.g., a truck, etc.) and transported to the fire scene together with a folding frame (120).

[0059] The size and volume of the digestion tank (110) can be changed as much as desired according to the loading capacity of the transport vehicle, and for example, a tank with a capacity of 1 ton can be applied.

[0060] Additionally, in one embodiment, a fire pump (300) may be placed on one side of the fire tank (110). The fire pump (300) supplies fire water contained in the fire tank (110) to a fire water spray lance (130) described later, and can generate sufficient water pressure to strongly spray the fire water into the battery located on the upper side of the electric bus.

[0061] Additionally, in one embodiment, the fire extinguishing tank (110), the fire extinguishing pump (300), and the fire extinguishing lance (130) described below may be connected to each other via a fire extinguishing supply line. The fire extinguishing supply line may be formed to have a sufficient length (e.g., 10 m) to reach the fire extinguishing lance (130) from the fire extinguishing tank (110).

[0062] Additionally, in one embodiment, the fire extinguishing water supply line may be made of a heat-dissipating material or may be treated with a heat-dissipating coating on the outside to prevent it from melting due to the high temperature generated from the battery located on the upper side of the electric bus.

[0063] In addition, although not shown in the drawing, in one embodiment, the fire extinguishing water supply line may be transported in a circular coiled state using a winch or the like, and may be automatically unwound when the folding frame (120) described later is separated from the transport vehicle and transported by an electric bus.

[0064]

[0065] The folding frame (120) can be transported to the fire scene while mounted on a transport vehicle, then detached from the transport vehicle and attached to the electric bus. It can basically remain folded until it is unfolded hydraulically. A more detailed description of this is as follows.

[0066] Figure 3 is a drawing showing the configuration of the folding frame (120) in more detail.

[0067] Looking at Figure 3, the folding frame (120) can be largely divided into a lower frame (121) that is mounted on the floor surface, and an upper frame (122) that is connected to the lower frame (121) by a hinge so that it can rotate.

[0068] More specifically, the lower frame (121) is fixed to the floor surface and serves to support the folding frame (120) itself so that it does not fall over, and a plurality of wheels may be arranged on the lower side of the lower frame (121) to facilitate movement.

[0069] In addition, in one embodiment, a hinge is arranged on the upper side of the lower frame (121) for the upper frame (122) to rotate, so that the upper frame (122) can be rotated from the lower frame (121) through the hinge to be upright in the upward direction. This is to minimize the volume by folding the upper frame (122) during normal or foldable frame (120) transportation, and to rotate the upper frame (122) from the lower frame (121) to become as high as the height of the electric bus during the process of preparing for fire suppression.

[0070] The upper frame (122) is shorter than the lower frame (121) discussed above or has a length corresponding to the length of the lower frame (121), and has a structure in which it rotates upward from the lower frame (121) through a hinge to unfold or rotates downward to fold.

[0071] This upper frame (122) can be rotated hydraulically from the lower frame (121) through a folding cylinder (123), which will be described below.

[0072] Figure 4 is a drawing showing a state in which the upper frame (122) is rotated from the lower frame (121) by the folding cylinder (123).

[0073] Referring to Fig. 4, the lower frame (121) and the upper frame (122) are connected to each other through a hinge, and furthermore, the lower frame (121) and the upper frame (122) are connected through a folding cylinder (123). The folding cylinder (123) is applied with a hydraulic cylinder, and the cylinder length can be reduced through hydraulic pressure to pull the upper frame (122) to be upright, or the cylinder length can be extended to push the upper frame (122) to be folded downward. This folding cylinder (123) is connected to a hydraulic pump (200) arranged on one side of the transport vehicle through a hydraulic supply line, and can be controlled through hydraulic pressure.

[0074] Here, the hydraulic pump (200) is connected to the folding cylinder (123) through a high-pressure hydraulic supply line, and by adjusting the cylinder rod length of the folding cylinder (123) through hydraulic pressure, the upper frame (122) can be pulled to be upright, or the upper frame (122) can be pushed to be folded downward.

[0075] On the upper side of the upper frame (122), an upper fixed frame (124) is arranged so that one side can rotate from the upper frame (122) by a hinge and is in close contact with the upper surface of the electric bus.

[0076] The upper fixed frame (124) can be connected to the upper frame (122) via a hinge so as to have a certain length in the forward direction (in the direction toward the electric bus) based on the upright state of the upper frame (122). The lower surface of the upper fixed frame (124) can be in close contact with the upper surface of the electric bus, and the length can be formed to be long enough to reach the center of the battery placed on the upper part of the electric bus.

[0077] In addition, the upper fixed frame (124) can be rotated up and down from the upper frame (122) via the upper fixed cylinder (125), which will be described below.

[0078] Figure 5 is a drawing showing a state in which the upper fixed frame (124) is rotated from the upper frame (122) by the upper fixed cylinder (125) and is pressed against the upper part of the electric bus.

[0079] Referring to Fig. 5, the upper fixed frame (124) is connected to the upper frame (122) through a hinge, and the upper fixed frame (124) and the upper frame (122) are connected through an upper fixed cylinder (125). The upper fixed cylinder (125) is equipped with a hydraulic cylinder, and the cylinder length is reduced through hydraulic pressure to pull the upper fixed frame (124) and slightly lift it upward, or the cylinder length is extended to push the upper fixed frame (124) and lower it downward, so that it can be brought into close contact with the upper surface of the electric bus.

[0080] That is, by slightly lifting the upper fixed frame (124) upward and positioning the upper fixed frame (124) on the upper surface of the electric bus, and then lowering the upper fixed frame (124) downward through the upper fixed cylinder (125), the frame is brought into close contact with the upper surface of the electric bus, thereby serving to secure the folding frame (120) so that it does not move or slide during the process of pushing through the battery placed on the upper surface of the electric bus or spraying high-pressure fire extinguishing water through the fire extinguishing water spray lance (130) described later.

[0081] This upper fixed cylinder (125) is connected to a hydraulic pump (200) placed on one side of the transport vehicle through a hydraulic supply line, and can be controlled through hydraulic pressure.

[0082] The hydraulic pump (200) is connected to the upper fixed cylinder (125) through a high-pressure hydraulic supply line, and by adjusting the cylinder rod length of the upper fixed cylinder (125) through hydraulic pressure, the upper fixed frame (124) can be slightly raised by pulling it, or the upper fixed frame (124) can be lowered by pushing it so that the lower surface of the upper fixed frame (124) is in close contact with the upper surface of the electric bus.

[0083] In addition, a fire extinguishing lance (130) for spraying fire extinguishing water, which will be described later, may be installed upright facing downward at the end of the upper fixed frame (124). The fire extinguishing lance (130) can pierce the battery placed on the upper part of the electric bus through hydraulic pressure and then spray high-pressure fire extinguishing water into the battery to extinguish a fire when the upper fixed frame (124) is in close contact with the upper surface of the electric bus. This will be described later.

[0084] Meanwhile, in order to correspond to the upper fixed frame (124), a lower fixed frame (126) that is in close contact with the lower surface of the electric bus is also provided on the lower frame (121). This will be examined as follows.

[0085]

[0086] Figure 6 is a drawing showing a state in which the lower fixed frame (126) is rotated from the lower frame (121) by the lower fixed cylinder (127) and is in close contact with the lower part of the electric bus.

[0087] Referring to Fig. 6, the lower fixed frame (126) is connected to the lower side of the lower frame (121) through a hinge, and the lower fixed frame (126) and the lower frame (121) are connected through a lower fixed cylinder (127). The lower fixed cylinder (127) is applied with a hydraulic cylinder, so that the length of the cylinder is reduced through hydraulic pressure to pull the lower fixed frame (126) and lower the end in a downward direction, or the length of the cylinder is extended to push the lower fixed frame (126) and raise the end upward, thereby allowing it to be in close contact with the lower surface of the electric bus.

[0088] That is, by slightly lowering the lower fixed frame (126) downward and positioning the lower fixed frame (126) on the lower surface of the electric bus, and then raising the lower fixed frame (126) upward through the lower fixed cylinder (127), the frame is brought into close contact with the lower surface of the electric bus, thereby serving to secure the folding frame (120) so that it does not move or slide during the process of pushing through the battery placed on the upper part of the electric bus or spraying high-pressure fire extinguishing water through the fire extinguishing water spray lance (130) described later.

[0089] These lower fixed cylinders (127) are connected to a hydraulic pump (200) placed on one side of the transport vehicle through a hydraulic supply line, and can be controlled through hydraulic pressure.

[0090] In addition, in one embodiment, the upper fixed cylinder (125) and the lower fixed cylinder (127) may be controlled simultaneously. For example, when hydraulic pressure is applied from the hydraulic pump (200) through the hydraulic supply line connected to each of the upper fixed cylinder (125) and the lower fixed cylinder (127), the upper fixed frame (124) connected to the upper fixed cylinder (125) is lifted upward, and the lower fixed frame (126) connected to the lower fixed cylinder (127) is lowered downward, so that the upper fixed frame (124) and the lower fixed frame (126) are separated from each other.

[0091] In this state, when the hydraulic direction of the hydraulic pump (200) is switched in the opposite direction while the folding frame (120) is moved so as to be adjacent to the side of the electric bus where the fire occurred, the upper fixed frame (124) connected to the upper fixed cylinder (125) is pressed against the upper surface of the electric bus while descending, and the lower fixed frame (126) connected to the lower fixed cylinder (127) is pressed against the lower surface of the electric bus while rising.

[0092] That is, since the upper fixed frame (124) and the lower fixed frame (126) are in a state of being narrowed from being apart from each other, as a result, the folding frame (120) can be firmly fixed to the electric bus by tightening the upper and lower parts of the electric bus.

[0093] In addition, a perforation cylinder (128) may be placed at the end of the upper fixed frame (124) discussed above to perforate the battery by pushing a lance (130) for injecting fire extinguishing water, which will be described later, toward the battery located on the upper part of the electric bus. This will be discussed as follows.

[0094] Figure 7 is a drawing showing a state in which a lance (130) for injecting fire extinguishing water is inserted toward the inside of the battery by a perforation cylinder (128) to perforate the battery.

[0095] Looking at Figure 7, in a state where the upper fixed frame (124) examined above is completely attached to the upper surface of the electric bus through the upper fixed cylinder (125), the lower end of the fire extinguishing water injection lance (130) placed upright at the end of the upper fixed frame (124) is attached to the upper surface of the electric bus.

[0096] In this state, by lowering the extinguishing water injection lance (130) through the perforation cylinder (128), the extinguishing water injection lance (130) is pushed downward by hydraulic pressure, thereby piercing the battery. This perforation cylinder (128) is connected to a hydraulic pump (200) arranged on one side of the transport vehicle through a hydraulic supply line, and can be controlled by hydraulic pressure.

[0097] At this time, the hydraulic pressure applied from the hydraulic pump (200) to the perforation cylinder (128) may be sufficient pressure to penetrate the upper surface of the electric bus and the battery located inside through the extinguishing water injection lance (130).

[0098] In this way, when the battery on the upper part of the electric bus is pierced by the hydraulic pressure of the perforation cylinder (128), fire extinguishment begins as fire extinguishing water is sprayed into the battery through the lower part of the fire extinguishing water spray lance (130).

[0099] In addition, in one embodiment, a mounting portion (129) is formed on one side of the folding frame (120) so as to be height-adjustable up and down, and is mounted on a transport vehicle through a hook-and-loop connection. This will be described as follows.

[0100] Figure 8 is a drawing showing a state in which the height of the mounting hook (129-1) is adjusted up and down from the lower frame (121) by the mounting cylinder (129-2).

[0101] Looking at Figure 8, the side of the lower frame (121) is provided with a plurality of hinges to enable height adjustment up and down, and a mounting portion (129) is arranged so that one side can be mounted on a transport vehicle through a hook-and-loop connection.

[0102] The mounting portion (129) may include a mounting hook means (129-1) having a ring shape that can be mounted on the rear side of a transport vehicle (e.g., a truck), and a mounting cylinder (129-2) that adjusts the vertical height of the mounting hook means (129-1).

[0103] The hanging means (129-1) for mounting is connected to the side of the lower frame (121) in a form that allows for height adjustment up and down through multiple hinges, and is connected to the mounting cylinder (129-2) and has a structure that is pulled upward or lowered depending on the change in the cylinder length of the mounting cylinder (129-2).

[0104] Accordingly, when the mounting cylinder (129-2) is pulled upward by the hydraulic pressure of the hydraulic pump (200) and the mounting hook means (129-1) is pressed against the rear of the transport vehicle, as the hydraulic pressure of the hydraulic pump (200) is applied in the opposite direction, the cylinder length of the mounting cylinder (129-2) increases, and the mounting hook means (129-1) is lowered and hooked to the rear of the transport vehicle to be mounted. Through this, the electric bus fire suppression device (100) can be mounted on the transport vehicle and transported.

[0105] Conversely, in order to separate the electric bus fire suppression device (100) from the transport vehicle, the mounting hook means (129-1) connected to the mounting cylinder (129-2) is pulled upward by the hydraulic pressure of the hydraulic pump (200), and then the electric bus fire suppression device (100) can be separated from the rear of the transport vehicle.

[0106]

[0107] The lance (130) for spraying fire extinguishing water can be installed vertically at the end of the upper fixed frame (124) among the folding frames (120) discussed above, and the perforation cylinder (128) discussed above is arranged on the upper side, so that when the perforation cylinder (128) is operated by hydraulic pressure applied from the hydraulic pump (200), it descends downwards and forcibly pierces the battery located on the upper part of the electric bus, and then sprays fire extinguishing water into the interior. This will be discussed as follows.

[0108] Figure 9 is a drawing showing a lance (130) for injecting digestive fluid in more detail.

[0109] Referring to FIG. 9, the extinguishing water injection lance (130) may include a lance head (131) that penetrates the inside by perforating the upper part of the battery through hydraulic pressure, and a extinguishing water nozzle (132) that is formed on the side of the body of the extinguishing water injection lance (131) and sprays extinguishing water outward.

[0110] More specifically, the lance head (131) has a shape in which the lower end protrudes sharply, and a material (e.g., alloy, etc.) having a strength that can easily penetrate not only the upper outer wall of the electric bus but also the upper part of the battery through the hydraulic pressure of the hydraulic pump (200) can be applied. In addition, in one embodiment, the lance head (131) can be connected so as to be replaceable from the extinguishing water spray lance (130), so that when the end of the lance head (131) becomes dull or partially damaged or dented, causing a deterioration in its function such that it cannot penetrate the upper part of the battery well, it can be configured to be replaced with a new lance head (131) from the extinguishing water spray lance (130).

[0111] In addition, a fire extinguishing water supply line can be connected to the side of the body of the fire extinguishing water injection lance (130), and the fire extinguishing water supply line can be connected to a fire extinguishing water pump (300) connected to the fire extinguishing water tank (110) discussed above. Accordingly, the fire extinguishing water can be strongly sprayed through the fire extinguishing water nozzle (132) by the water pressure applied by the fire extinguishing water pump (300).

[0112] At this time, as shown in Fig. 9(b), the body of the extinguishing water injection lance (130) can be formed in multiple stages, and a extinguishing water nozzle (132) can be placed on the side of each stage.

[0113] Additionally, an internal supply line may be formed inside the extinguishing water injection lance (130) to inject extinguishing water supplied through the extinguishing water supply line.

[0115] Next, we will examine in order the entire process of transporting the electric bus fire suppression device (100) examined above to the electric bus fire scene via a transport vehicle and extinguishing the fire.

[0116] Figure 10 is a drawing showing the process of extinguishing a fire in an electric bus battery in sequence using an electric bus fire extinguishing device (100).

[0117] Referring to Fig. 10, with an electric bus fire suppression device (100) mounted on a transport vehicle, the transport vehicle moves near an electric bus where a fire has broken out (S1001), and a mounting hook means (129-1) connected to a mounting cylinder (129-2) is pulled by hydraulic pressure of a hydraulic pump (200), and then the folding frame (120) is separated from the transport vehicle (S1002).

[0118] In this state, the hydraulic pump (200) applies hydraulic pressure to the folding cylinder (123) to unfold the upper frame (122) from the lower frame (121) and stand upright (S1003). At the same time, the hydraulic pump (200) applies hydraulic pressure to the upper fixed frame (124) and the lower fixed frame (126) to pull them, thereby causing the ends of the upper fixed frame (124) and the lower fixed frame (126) to spread apart (S1004).

[0119] Next, when the folding frame (120) itself is pressed against the side of the electric bus where a fire has occurred (S1005), the hydraulic pump (200) applies hydraulic pressure in opposite directions to the upper fixed frame (124) and the lower fixed frame (126), thereby narrowing the ends of the upper fixed frame (124) and the lower fixed frame (126), thereby firmly fixing the folding frame (120) to the electric bus and preventing it from moving (S1006).

[0120] In this state, the hydraulic pump (200) applies hydraulic pressure to the perforation cylinder (128) to push the extinguishing water injection lance (130) downward, thereby piercing the battery (meaning a battery in a state of thermal runaway) provided on the upper side of the electric bus (S1007).

[0121] Next, the fire pump (300) supplies the fire extinguishing water contained in the fire extinguishing water tank (110) to the fire extinguishing water spraying lance (130), so that the fire extinguishing water is sprayed into the battery through the fire extinguishing water nozzle (132) of the fire extinguishing water spraying lance (130) through strong water pressure, thereby extinguishing the fire (S1008). After the fire extinguishing is complete, the steps S1001 to S1008 discussed above are performed in reverse order so that the battery can be transported again via a transport vehicle.
