Description

Electric bus fire suppression device capable of loading and unloading via hydraulic cylinders

[0001] The present invention relates to an electric bus fire suppression device capable of loading and unloading via a hydraulic cylinder, and more specifically, to an electric bus fire suppression device capable of loading and unloading via a hydraulic cylinder, which enables easy loading and unloading from a transport vehicle via a hydraulic cylinder, and which enables rapid extinguishment of 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 above-mentioned problem, and provides an electric bus fire suppression device capable of loading and unloading through a hydraulic cylinder, which enables easy loading and unloading from a transport vehicle through a hydraulic cylinder, and which enables rapid extinguishment of 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) capable of loading and unloading through a hydraulic cylinder according to one embodiment of the present invention includes a rotation auxiliary plate (110) installed at the rear of a loading box of a transport vehicle, a hydraulic cylinder (120) arranged in the loading box of the transport vehicle, a folding frame (130) that is opened or closed by hydraulic pressure, a stand (140) arranged on one side of the folding frame (130) and configured to be hooked to an end of a cylinder rod (121) that is drawn out from the hydraulic cylinder (120), and a fire extinguishing water spraying lance (150) arranged on the folding frame (130) and that sprays fire extinguishing water supplied from a fire extinguishing water tank mounted on the transport vehicle into the battery after piercing a battery arranged on the upper part of the electric bus, and the stand (140) is secured to the rotation auxiliary plate (110) in a state of being hooked to an end of the cylinder rod (121) so as to be maintained in a state of being loaded on the transport vehicle, and the cylinder rod (121) When unloading, the holder (140) is moved toward the ground through a sliding motion while in close contact with the rotation auxiliary plate (110), and the end of the cylinder rod (121) is released from the engaging connection, thereby separating the holder (140) and the rotation auxiliary plate (110) from each other, so that unloading can be completed.

[0008] According to one embodiment of the present invention, the rotation auxiliary plate (110) may include a base plate (111) arranged at the rear of the bottom surface of the loading box, a mounting rod (112) arranged on the upper side of the base plate (111) and on which the stand (140) is mounted, and a hooking means (113) arranged at a predetermined distance from the mounting rod (112) on the upper side of the base plate (111) and for hooking and connecting one side of the stand (140) when the stand (140) is mounted on the mounting rod (112).

[0009] According to one embodiment of the present invention, the folding frame (130) comprises: a lower frame (131), an upper frame (132) connected by a hinge so that one side of the lower frame (131) can rotate; a folding cylinder (133) connected between the lower frame (131) and the upper frame (132) to control the rotation of the upper frame (132) through hydraulic pressure; an upper fixed frame (134) connected by a hinge so that one side of the upper frame (132) can rotate and is in close contact with the upper surface of the electric bus; an upper fixed cylinder (135) connected between the upper frame (132) and the upper fixed frame (134) to control the rotation of the upper fixed frame (134) through hydraulic pressure; a lower fixed frame (136) connected by a hinge so that one side of the lower frame (131) can rotate and is in close contact with the lower surface of the electric bus; a folding cylinder (133) connected between the lower frame (131) and the lower fixed frame (136) to control the rotation of the upper fixed frame (134) through hydraulic pressure. It may include a lower fixed cylinder (137) that controls the rotation of the lower fixed frame (136) and a perforation cylinder (138) that is positioned at the end of the upper fixed frame (134) and pushes the extinguishing water injection lance (150) located on the upper part of the electric bus toward the battery.

[0010] According to one embodiment of the present invention, the folding cylinder (133), the upper fixed cylinder (135), the lower fixed cylinder (137), and the perforation cylinder (138) 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.

[0011] According to one embodiment of the present invention, the stand (140) is placed on one side of the lower frame (131), has a certain length, and can slide along the mounting rod (112) while being mounted on the mounting rod (112).

[0012] According to one embodiment of the present invention, the stand (140) may include a rotational hooking jaw (141) for rotating at a 90-degree angle by hooking one side of the mounting hook (112) while sliding along the mounting hook (112) while being mounted on the mounting hook (112) during unloading, and a rotation-limiting hook (142) for engaging with the hooking engaging means (113) during loading to limit rotation.

[0013] According to one embodiment of the present invention, the extinguishing water injection lance (150) can be connected to a extinguishing water pump (300) disposed on one side of the extinguishing water tank through a extinguishing water supply line to supply extinguishing water.

[0014] The fire extinguishing lance (150) according to one embodiment of the present invention includes a lance head (151) that pierces the upper part of the battery through hydraulic pressure and a fire extinguishing nozzle (152) that is formed on the side of the fire extinguishing lance (150) body and sprays the fire extinguishing water outward, and the lance head (151) can be connected in a replaceable form from the fire extinguishing lance (150) body.

[0015] According to one embodiment of the present invention, the body of the extinguishing water injection lance (150) is formed in multiple stages, and the extinguishing water nozzle (152) can be respectively arranged in each stage.

[0016] According to one embodiment of the present invention, the perforation cylinder (138) and the extinguishing water injection lance (150) can be configured to be directionally changed by releasing a bolt from the end of the upper fixed frame (134).

[0017] According to the present invention, there is an advantage in that loading and unloading from a transport vehicle is easily accomplished through a hydraulic cylinder.

[0018] In addition, according to the present invention, the direction of the perforation cylinder and the extinguishing water injection lance can be easily switched by releasing the bolt, so that the fire can be quickly extinguished by hydraulically drilling the battery placed on the side of the overturned electric bus and injecting extinguishing water.

[0019] In addition, according to the present invention, there is an advantage in that the fire can be quickly extinguished by hydraulically piercing the battery placed on the upper part of the electric bus while in close contact with the electric bus where the fire has occurred and injecting fire extinguishing water.

[0020] 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.

[0021] 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 suppress a fire.

[0061] Hereinafter, specific details for implementing the present invention will be described in detail with reference to the attached drawings. However, in the following description, specific descriptions of widely known functions or configurations will be omitted if they may unnecessarily obscure the gist of the present invention.

[0062]

[0063] FIG. 1 is a drawing schematically showing the overall configuration of an electric bus fire suppression device (100) capable of loading and unloading through a hydraulic cylinder 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) capable of loading and unloading through the hydraulic cylinder illustrated in FIG. 1 is loaded onto a transport vehicle.

[0064] Looking at FIGS. 1 and 2, an electric bus fire suppression device (100) capable of loading and unloading through a hydraulic cylinder according to one embodiment of the present invention may largely include a rotation auxiliary plate (110), a hydraulic cylinder (120), a folding frame (130), a stand (140), and a lance for spraying fire extinguishing water (150).

[0065] Here, a fire extinguishing tank can be installed in the loading area of ​​a transport vehicle (e.g., a truck, etc.).

[0066] The fire extinguishing tank 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 and transported to the fire scene together with a folding frame (130).

[0067] These fire extinguishing tanks can be applied in any size or volume depending on the loading capacity of the transport vehicle, and for example, a tank with a capacity of 1 ton can be applied.

[0068] Additionally, in one embodiment, a fire pump (300) may be placed on one side of the fire tank. The fire pump (300) supplies fire water contained in the fire tank to a fire water spray lance (150), and can generate sufficient water pressure to powerfully spray the fire water into the battery located on the upper side of the electric bus.

[0069] Additionally, in one embodiment, the fire extinguishing tank, the fire extinguishing pump (300), and the fire extinguishing lance (150) 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 (150) from the fire extinguishing tank.

[0070] 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.

[0071] 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 (130) described later is separated from the transport vehicle and transported by an electric bus.

[0072]

[0073] The rotation auxiliary plate (110) is installed at the rear of the loading compartment of the transport vehicle, and can serve to secure the folding frame (130) so that it does not separate during transport by the transport vehicle, and can serve as a guide for the mounting and rotation of the stand (140) during unloading. This will be discussed as follows.

[0074] Figure 3 is a drawing showing the configuration of the rotation auxiliary plate (110) in more detail.

[0075] Referring to FIG. 3, the rotation auxiliary plate (110) may include a base plate (111) arranged at the rear of the bottom surface of the loading box, a mounting rod (112) arranged on the upper side of the base plate (111) and on which a stand (140) is mounted, and a mounting rod (112) arranged at a certain distance from the upper side of the base plate (111), and a hooking connection means (113) for hooking one side of the stand (140) while the stand (140) is mounted on the mounting rod (112).

[0076] The base plate (111) can be firmly installed on the rear of the bottom of the loading box of the transport vehicle, and a fixing ring (112) and a hooking means (113) can be arranged at regular intervals on the upper side.

[0077] At this time, the mounting ring (112) can serve as a mounting space for the mounting stand (140) described later to be mounted, and as a rotation axis for the mounting stand (140) to be rotated at a 90-degree angle during the unloading or loading process.

[0078] The hooking connection means (113) is formed to have a cross-section in the shape of the letter 'L' so that one side of the stand (140) described later can be hooked, and when the folding frame (130) is loaded onto the transport vehicle, the stand (140) is hooked by the hooking connection means (113), so that it can be firmly fixed without being separated from the rotation auxiliary plate (110). This will be described later.

[0079]

[0080] The folding frame (130) 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 hydraulically unfolded. A more detailed description of this is as follows.

[0081] Figure 4 is a drawing showing the configuration of the folding frame (130) in more detail.

[0082] Looking at Figure 4, the folding frame (130) can be largely divided into a lower frame (131) that is mounted on the floor surface, and an upper frame (132) that is connected to the lower frame (131) by a hinge so as to be rotatable.

[0083] More specifically, the lower frame (131) is fixed to the floor surface and serves to support the folding frame (130) itself so that it does not fall over, and a plurality of wheels may be arranged on the lower side of the lower frame (131) to facilitate movement.

[0084] In addition, in one embodiment, a hinge is arranged on the upper side of the lower frame (131) for the upper frame (132) to rotate, so that the upper frame (132) can be rotated from the lower frame (131) through the hinge to be upright in the upward direction. This is to minimize the volume by folding the upper frame (132) during normal or foldable frame (130) transportation, and to rotate the upper frame (132) from the lower frame (131) to become as high as the height of the electric bus during the process of preparing for fire suppression.

[0085] The upper frame (132) is shorter than the lower frame (131) discussed above or has a length corresponding to the length of the lower frame (131), and has a structure in which it rotates upward from the lower frame (131) through a hinge to unfold or rotates downward to fold.

[0086] This upper frame (132) can be rotated hydraulically from the lower frame (131) through a folding cylinder (133), which will be described below.

[0087] Figure 5 is a drawing showing a state in which the upper frame (132) is rotated from the lower frame (131) by the folding cylinder (133).

[0088] Referring to Fig. 5, the lower frame (131) and the upper frame (132) are connected to each other through a hinge, and furthermore, the lower frame (131) and the upper frame (132) are connected through a folding cylinder (133). The folding cylinder (133) is applied with a hydraulic cylinder, and the cylinder length can be reduced through hydraulic pressure to pull the upper frame (132) to be upright, or the cylinder length can be extended to push the upper frame (132) to be folded downward. This folding cylinder (133) 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.

[0089] Here, the hydraulic pump (200) is connected to the folding cylinder (133) through a high-pressure hydraulic supply line, and by adjusting the cylinder rod length of the folding cylinder (133) through hydraulic pressure, the upper frame (132) can be pulled to be upright, or the upper frame (132) can be pushed to be folded downward.

[0090] On the upper side of the upper frame (132), an upper fixed frame (134) is arranged so that one side can rotate from the upper frame (132) by a hinge and is in close contact with the upper surface of the electric bus.

[0091] The upper fixed frame (134) may be connected to the upper frame (132) 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 (132). The lower surface of the upper fixed frame (134) may be in close contact with the upper surface of the electric bus, and the length may be formed to be sufficient to reach the center of the battery placed on the upper part of the electric bus.

[0092] In addition, the upper fixed frame (134) can be rotated up and down from the upper frame (132) via the upper fixed cylinder (135), which will be described below.

[0093]

[0094] Figure 6 is a drawing showing a state in which the upper fixed frame (134) and the lower fixed frame (136) are rotated from the upper frame (132) and the lower frame (131), respectively, by the upper fixed cylinder (135) and the lower fixed cylinder (137) and are in close contact with the upper and lower parts of the electric bus.

[0095] Referring to Fig. 6, the upper fixed frame (134) is connected to the upper frame (132) through a hinge, and the upper fixed frame (134) and the upper frame (132) are connected through an upper fixed cylinder (135). The upper fixed cylinder (135) is equipped with a hydraulic cylinder, and the length of the cylinder is reduced through hydraulic pressure to pull the upper fixed frame (134) and slightly lift it upward, or the length of the cylinder is extended to push the upper fixed frame (134) and lower it downward, so that it can be brought into close contact with the upper surface of the electric bus.

[0096] That is, by slightly lifting the upper fixed frame (134) upward and positioning the upper fixed frame (134) on the upper surface of the electric bus, and then lowering the upper fixed frame (134) downward through the upper fixed cylinder (135), the frame is brought into close contact with the upper surface of the electric bus, thereby serving to fix the folding frame (130) 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 (150) described later.

[0097] This upper fixed cylinder (135) 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.

[0098] The hydraulic pump (200) is connected to the upper fixed cylinder (135) through a high-pressure hydraulic supply line, and by adjusting the cylinder rod length of the upper fixed cylinder (135) through hydraulic pressure, the upper fixed frame (134) can be slightly raised by pulling it, or the upper fixed frame (134) can be lowered downward by pushing it so that the lower surface of the upper fixed frame (134) is in close contact with the upper surface of the electric bus.

[0099] In addition, a fire extinguishing lance (150) for spraying fire extinguishing water, which will be described later, can be installed upright facing downward at the end of the upper fixed frame (134). The fire extinguishing lance (150) can extinguish a fire by piercing a battery placed on the upper part of the electric bus through hydraulic pressure and then spraying high-pressure fire extinguishing water into the battery when the upper fixed frame (134) is in close contact with the upper surface of the electric bus.

[0100] In addition, the lower fixed frame (136) is connected to the lower side of the lower frame (131) through a hinge, and the lower fixed frame (136) and the lower frame (131) are connected through a lower fixed cylinder (137). The lower fixed cylinder (137) is applied with a hydraulic cylinder, so that the cylinder length is reduced through hydraulic pressure to pull the lower fixed frame (136) and lower the end in a downward direction, or the cylinder length is extended to push the lower fixed frame (136) and raise the end upward, thereby allowing it to be in close contact with the lower surface of the electric bus.

[0101] That is, by slightly lowering the lower fixed frame (136) downward and positioning the lower fixed frame (136) on the lower surface of the electric bus, and then raising the lower fixed frame (136) upward through the lower fixed cylinder (137), the lower fixed frame (136) is brought into close contact with the lower surface of the electric bus, thereby serving to secure the folding frame (130) 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 (150) described later.

[0102] These lower fixed cylinders (137) 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.

[0103] In addition, in one embodiment, the upper fixed cylinder (135) and the lower fixed cylinder (137) 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 (135) and the lower fixed cylinder (137), the upper fixed frame (134) connected to the upper fixed cylinder (135) is lifted upward, and the lower fixed frame (136) connected to the lower fixed cylinder (137) is lowered downward, so that the upper fixed frame (134) and the lower fixed frame (136) are separated from each other.

[0104] In this state, when the hydraulic direction of the hydraulic pump (200) is switched in the opposite direction while the folding frame (130) is moved so as to be adjacent to the side of the electric bus where the fire occurred, the upper fixed frame (134) connected to the upper fixed cylinder (135) is pressed against the upper surface of the electric bus while descending, and the lower fixed frame (136) connected to the lower fixed cylinder (137) is pressed against the lower surface of the electric bus while rising.

[0105] That is, since the upper fixed frame (134) and the lower fixed frame (136) are in a state of being narrowed from being apart from each other, as a result, the folding frame (130) can be firmly fixed to the electric bus by tightening the upper and lower parts of the electric bus.

[0106] In addition, a perforation cylinder (138) may be placed at the end of the upper fixed frame (134) discussed above to perforate the battery by pushing a lance (150) 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.

[0107] Figure 7 is a drawing showing a state in which a lance (150) for injecting fire extinguishing water is inserted toward the inside of the battery by a perforation cylinder (138) to perforate the battery.

[0108] Looking at Figure 7, in a state where the upper fixed frame (134) examined above is completely attached to the upper surface of the electric bus through the upper fixed cylinder (135), the lower end of the fire extinguishing water injection lance (150) placed upright at the end of the upper fixed frame (134) is attached to the upper surface of the electric bus.

[0109] In this state, by lowering the extinguishing water injection lance (150) through the perforation cylinder (138), the extinguishing water injection lance (150) is pushed downward by hydraulic pressure, thereby piercing the battery. This perforation cylinder (138) 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.

[0110] At this time, the hydraulic pressure applied from the hydraulic pump (200) to the perforation cylinder (138) may be sufficient pressure to pierce the upper surface of the electric bus and the battery located inside through the extinguishing water injection lance (150).

[0111] In this way, when the battery on the top of the electric bus is pierced by the hydraulic pressure of the perforation cylinder (138), fire extinguishing begins as fire extinguishing water is sprayed into the battery through the lower side of the fire extinguishing water spray lance (150).

[0112] In addition, in one embodiment, a hooking ring (131-1) for hooking a hooking ring (121-1) provided at the end of a cylinder rod (121) of a hydraulic cylinder (120) may be placed on one side of the lower frame (131), more specifically, on the upper side of the position where the stand (140) described later is installed.

[0113] The hook-type ring (131-1) can be hooked by a hook ring (121-1) provided at the end of the cylinder rod (121) of the hydraulic cylinder (120), and can be a point that is pulled during the process of loading onto a transport vehicle through the hook-type connection, or conversely, can be a point that is pushed during the process of unloading from the transport vehicle.

[0114]

[0115] The stand (140) is installed on one side of the lower frame (131) discussed above, and can slide along the mounting ring (112) when unloading while being mounted on the mounting ring (112) discussed above. This will be examined in more detail as follows.

[0116] FIG. 8 is a drawing showing the configuration of the stand (140) in more detail, FIG. 9 is a drawing showing the process of unloading the folding frame (130) from the transport vehicle through the withdrawal of the cylinder rod (121), and FIG. 9 is a drawing showing the process of loading the folding frame (130) onto the transport vehicle through the introduction of the cylinder rod (121).

[0117] Looking at Fig. 8, the stand (140) can be positioned on the lower side of the hanging rod (131-1) in the lower frame (131).

[0118] This stand (140) can be mounted on one side of the mounting ring (112) of the rotation auxiliary plate (110), and as shown in FIG. 9, when the cylinder rod (121) is pulled out by hydraulic pressure, the hook (121-1) provided at the end of the cylinder rod (121) pushes the mounting ring (131-1), so that the stand (140) is pushed toward the rear of the transport vehicle while mounted on the mounting ring (112).

[0119] In addition, a rotational catch (141) is formed on one side of the stand (140) so that one side is caught on the mounting ring (112) and rotated at a 90-degree angle during the process of sliding along the mounting ring (112) while mounted on the mounting ring (112).

[0120] The pivoting catch (141) has a structure that catches the mounting ring (112) when the stand (140) is pushed out as much as possible while being mounted on the mounting ring (112), and at this time, the stand (140) naturally rotates at a 90-degree angle with the mounting ring (112) as the rotation axis due to the load of the folding frame (130).

[0121] At this time, since the hook (121-1) provided at the end of the cylinder rod (121) is hooked to the hook ring (131-1), the folding frame (130) does not rotate rapidly, but rather slowly rotates at a 90-degree angle, and the lower side becomes closer to the ground.

[0122] After the rotation is completed, the hanging ring (121-1) is separated from the hanging rod (131-1), thereby completing the unloading of the folding frame (130).

[0123]

[0124] Conversely, when the folding frame (130) is loaded onto a transport vehicle, the lower frame (131) is positioned adjacent to the rear of the transport vehicle, and the hook (121-1) is hooked to the hooking rod (131-1). As the cylinder rod (121) of the hydraulic cylinder (120) is pulled in, the hook (121-1) pulls the hooking rod (131-1), and the pivoting hook (141) is hooked to the fixing rod (112), and the stand (140) rotates upward again at a 90-degree angle.

[0125] In addition, as the hook (121-1) continues to pull the hooking ring (131-1), the stand (140) slides inward toward the loading compartment of the transport vehicle while being secured to the securing ring (112).

[0126] At this time, a rotation limiting ring (142) may be placed on one side of the stand (140) to limit rotation by being hooked to the hooking connection means (113).

[0127] The rotation limiting ring (142) is naturally caught and connected to the catch-joining means (113) having an ‘ㄱ’ shaped cross-section during the sliding movement process while the stand (140) is secured to the securing ring (112).

[0128] At this time, since the hook ring (121-1) is maintained in a hooked state with the hook ring (131-1), the holder (140) is firmly fixed without being separated or rotated from the rotation auxiliary plate (110) unless the hook ring (121-1) is separated from the hook ring (131-1).

[0129]

[0130] The lance (150) for spraying fire extinguishing water can be installed vertically at the end of the upper fixed frame (134) among the folding frames (130) discussed above, and the perforation cylinder (138) discussed above is arranged on the upper side, so that when the perforation cylinder (138) is operated by hydraulic pressure applied from the hydraulic pump (200), it can come down in a downward direction, forcibly pierce the battery located on the upper part of the electric bus, and then spray fire extinguishing water into the interior. This will be discussed as follows.

[0131] Figure 10 is a drawing showing a lance (150) for injecting digestive fluid in more detail.

[0132] Referring to FIG. 10, the extinguishing water injection lance (150) may include a lance head (151) that penetrates the inside by perforating the upper part of the battery through hydraulic pressure, and a extinguishing water nozzle (152) that is formed on the side of the body of the extinguishing water injection lance (131) and sprays extinguishing water outward.

[0133] More specifically, the lance head (151) 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 (151) can be connected so as to be replaceable from the extinguishing water spray lance (150), so that when the function of the lance head (151) deteriorates, such as when the end of the lance head (151) becomes dull or partially damaged or dented, making it difficult to penetrate the upper part of the battery, it can be configured to be replaced with a new lance head (151) from the extinguishing water spray lance (150).

[0134] In addition, a fire extinguishing water supply line may be connected to the side of the body of the fire extinguishing water injection lance (150), and the fire extinguishing water supply line may be connected to a fire extinguishing water pump (300) connected to the fire extinguishing water tank discussed above. Accordingly, the fire extinguishing water can be strongly sprayed through the fire extinguishing water nozzle (152) by the water pressure applied by the fire extinguishing water pump (300).

[0135] At this time, as shown in Fig. 11(b), the body of the extinguishing water injection lance (150) can be formed in multiple stages, and a extinguishing water nozzle (152) can be placed on the side of each stage.

[0136] Additionally, an internal supply line may be formed inside the extinguishing water injection lance (150) to inject extinguishing water supplied through the extinguishing water supply line.

[0137]

[0138] In addition, in one embodiment, the perforation cylinder (138) and the extinguishing water injection lance (150) are configured to be directionally changed by releasing the bolt from the end of the upper fixed frame (134), so that when the battery of the electric bus to be perforated is located on the side rather than the upper side due to the electric bus overturning, the battery of the electric bus can be perforated from the side. This will be described as follows.

[0139] Figure 11 is a drawing showing a state in which a lance (150) for spraying fire extinguishing water is inserted toward the inside of the battery from the side of an overturned electric bus to perforate the battery.

[0140] Referring to Fig. 11, if an electric bus on fire overturns and the battery faces the side instead of the top, the bolts at the end of the upper fixed frame (134) can be released to turn the direction of the perforation cylinder (138) and the fire extinguishing lance (150) 180 degrees so that the fire extinguishing lance (150) faces the battery of the electric bus. In this state, the fire extinguishing lance (150) is pushed downward by hydraulic pressure to pierce the battery, and with the battery located on the side of the electric bus pierced by hydraulic pressure, the fire extinguishing is initiated as the fire extinguishing lance (150) sprays fire extinguishing water into the battery through the lower side of the fire extinguishing lance (150).

[0141]

[0142] While the present invention has been described in connection with certain embodiments herein, it should be understood that various modifications and variations can be made without departing from the scope of the invention as understood by those skilled in the art. Furthermore, such modifications and variations should be considered to fall within the scope of the claims appended to this specification.

[0143] According to the present invention, a fire can be quickly extinguished by hydraulically piercing a battery placed on top of an electric bus and injecting fire extinguishing water while in close contact with the electric bus where a fire has occurred. The present invention is a technology that can be widely used in the electric bus and firefighting industries to realize its practical and economic value.
