Description

[Technical Field]

[0001] The present invention relates to a fire extinguishing water spraying device, and more particularly to a water pressure-activated fire extinguishing water spraying device that not only reduces the complexity and expense of preparing a separate drive device for activation by being activated by water pressure, but also enables the direction of fire extinguishing water to be changed, thereby discharging fire extinguishing water according to the location of a fire outbreak on a vehicle, thereby enabling smooth fire suppression. [Background technology]

[0002] Conventional automobiles are powered by internal combustion engines, which causes problems such as air pollution due to exhaust fumes.

[0003] For these reasons, electric vehicles have been attracting attention in recent years.

[0004] Electric vehicles are driven by a motor powered by a battery, which means that they do not emit exhaust gases and therefore prevent air pollution, they also emit minimal noise while driving, which helps reduce driver fatigue, and they have fewer parts, which means that maintenance costs can be reduced.As a result, electric vehicles are rapidly becoming more popular than ordinary cars that use internal combustion engines.

[0005] However, electric vehicles have a problem in that if a fire occurs, it is difficult to extinguish.

[0006] In other words, if a fire breaks out in the battery pack of an electric vehicle due to an external impact or an internal short circuit, it is difficult to extinguish the fire in the early stages due to thermal runaway phenomena, and the fire spreads to surrounding vehicles, causing greater damage.

[0007] In particular, when the produced electric vehicles are transported by ship, the vehicles are placed adjacent to each other to make efficient use of space, which creates the problem that if a fire breaks out in one vehicle, the fire can quickly spread to surrounding vehicles, causing even greater damage.

[0008] Meanwhile, when a fire breaks out in an electric vehicle, the fire is usually extinguished using a "fire-extinguishing water spraying device" as disclosed in Korean Patent Publication No. 10-2023-0146361.

[0009] However, because conventional fire-extinguishing water spraying devices only spray water forward, it is difficult for the water to reach the battery packs located in the floor of electric vehicles, making it difficult to extinguish the fire if it breaks out in the battery pack of an electric vehicle.

[0010] In addition, typical fire extinguishing water spraying devices are usually moved by workers pushing or pulling them, which makes them difficult to move to the fire site and poses a risk to worker safety.

[0011] For this reason, some fire extinguishing water spraying devices are provided with a separate driving device such as a motor.

[0012] However, in the case of a fire extinguishing water spraying device that is activated by a separate drive device, there is the problem of the complexity and expense involved in preparing a separate drive device.

[0013] For the above reasons, attempts have been made in the field to develop a fire extinguishing water spraying device that can be started smoothly without a separate drive unit, and that can more effectively extinguish a fire by spraying fire extinguishing water in accordance with the location of the fire on the vehicle. However, the reality is that no satisfactory results have been achieved at present. [Prior art documents] [Patent documents]

[0014] [Patent Document 1] Republic of Korea Patent Publication No. 10-2023-0146361 Summary of the Invention [Problem to be solved by the invention]

[0015] The present invention has been proposed to solve the problems of the prior art as described above, and aims to provide a fire extinguishing water spraying device that can be smoothly started without a separate drive device, and can also spray fire extinguishing water according to the location of the fire outbreak on the vehicle. [Means for solving the problem]

[0016] In order to achieve the above object, the present invention provides a fire extinguishing device comprising: a support part having a plurality of support pieces arranged at intervals in the front and rear directions; a fire extinguishing water spray part hinged to one of the support pieces of the support part and having a plurality of nozzles arranged at intervals on an upper surface thereof; a first starting part connected between one end and the other end of the support pieces of the support part and having a plurality of wheels that come into contact with the ground on one side; a second starting part connected between the other end and the other end of the support pieces of the support part and having a plurality of wheels that come into contact with the ground on one side; and a control part spaced from the support part and having one end connected to a fire hydrant, for controlling and interrupting the flow of fire extinguishing water in each of a first fire extinguishing water supply pipe that extends from the other end to the fire extinguishing water spray part, a second fire extinguishing water supply pipe that extends from the other end to the first starting part, and a third fire extinguishing water supply pipe that extends from the other end to the second starting part, The present invention proposes a water-pressure-activated fire extinguishing water spraying device, characterized in that the first and second starting units rotate the wheels due to the water pressure caused by the flow of water supplied through the second and third water supply pipes inside the units.

[0017] The extinguishing water spraying unit includes a rotation module that is operated by the hydraulic action of the extinguishing water supplied through the first extinguishing water supply pipe, and can rotate forward and backward within a certain angle range by the operation of the rotation module.

[0018] The rotation module may be a cylinder in which the rod moves in and out under the hydraulic action of fire extinguishing water.

[0019] The wheels of the first and second starting units include water wheels connected to their respective rotation shafts, and can rotate due to the rotation of the water wheels caused by the hydraulic action of the fire extinguishing water supplied through the second and third fire extinguishing water supply pipes.

[0020] The first and second starting units each include an outlet for discharging the extinguishing water supplied through the second and third extinguishing water supply pipes to the outside.

[0021] The control unit can interrupt the flow of fire extinguishing water in each of the first fire extinguishing water supply pipe, the second fire extinguishing water supply pipe, and the third fire extinguishing water supply pipe by opening and closing valves provided in each of the first fire extinguishing water supply pipe, the second fire extinguishing water supply pipe, and the third fire extinguishing water supply pipe.

[0022] At least one of the multiple nozzles arranged in the fire extinguishing water spraying unit is arranged on a drilling member that moves up and down and rotates by hydraulic pressure, and the drilling member that moves up and down and rotates forms a hole in the bottom of the electric vehicle where a fire has occurred, allowing fire extinguishing water to be sprayed directly onto the battery pack attached to the bottom of the electric vehicle.

[0023] The present invention may further include a camera disposed in either the support section or the fire extinguishing water spray section to capture images in front; and a monitor disposed in the control section to display images captured by the camera. [Effects of the Invention]

[0024] The water discharge device activated by water pressure according to the present invention includes a first activation unit and a second activation unit each having a plurality of wheels that come into contact with the ground. The wheels of the first activation unit and the second activation unit rotate due to the water pressure acting on the inside of the device as the water supplied through the second and third water supply pipes flows through the first and second activation units. Therefore, the device can be activated without a separate drive unit by the rotation of the wheels of the first and second activation units due to the water pressure, thereby reducing the complexity and expense of preparing a separate drive unit for activation.

[0025] The water pressure-activated fire extinguishing water spraying device according to the present invention includes a rotation module whose water spraying unit is operated by the water pressure of the extinguishing water supplied through the first water supply pipe, and the rotation module can rotate forward and backward within a certain angle range by operating it. As a result, the water can be sprayed in both a lying and standing position by rotating forward and backward by operating the rotation module. In particular, by spraying the water upward in a lying position, the water can be smoothly delivered to the battery pack located at the bottom of the electric vehicle where the fire has occurred, thereby smoothly extinguishing the fire in the electric vehicle.

[Figure 6]10 is an exemplary view showing the operation of a rotation module of the fire extinguishing water spraying unit in the fire extinguishing water spraying device activated by water pressure according to the present invention; FIG. DETAILED DESCRIPTION OF THE INVENTION

[0027] The present invention will be described in detail below with reference to the accompanying drawings.

[0028] As shown in FIG. 1, the fire extinguishing water spraying device (A) activated by water pressure according to the present invention includes a support part (100), a fire extinguishing water spraying part (200), a first activation part (300), a second activation part (400), and a control part (500).

[0029] The support portion (100) of the present invention includes a plurality of support pieces (110) spaced apart from one another in the front and rear directions.

[0030] Therefore, the support piece (110) can support the fire extinguishing water spraying unit (200), the first starting unit (300) and the second starting unit (400).

[0031] Such a support part (100) only supports the fire extinguishing water spray part (200), the first starting part (300) and the second starting part (400) via the support piece (110) and does not have any other special functions, so a detailed description of the support part (100) will be omitted.

[0032] The fire extinguishing water discharge unit (200) of the present invention includes a plurality of nozzles (210) spaced apart in the longitudinal direction on the upper surface.

[0033] Therefore, the extinguishing water flowing into the extinguishing water spraying unit (200) can be sprayed to the outside by the plurality of nozzles (210).

[0034] The fire extinguishing water spraying unit (200) is hinged to one of the support pieces (110) of the support unit (100), thereby allowing the fire extinguishing water spraying unit (200) to rotate on the support unit (100).

[0035] At this time, the fire extinguishing water spraying unit 200 includes a rotation module 220, and can rotate by operating the rotation module 220.

[0036] Here, the rotary module 220 can be operated by the hydraulic action of the fire extinguishing water supplied through the first fire extinguishing water supply pipe 230, which will be described later.

[0037] That is, the rotation module (220) can be a cylinder (symbol omitted) in which a rod (symbol omitted) moves in and out due to the hydraulic action of the extinguishing water, and by connecting the tip of the rod that moves in and out due to the hydraulic action to the extinguishing water spraying unit (200), the extinguishing water spraying unit (200) can rotate forward and backward within a certain angle range as the rod moves in and out due to the hydraulic action of the extinguishing water.

[0038] Meanwhile, a branch pipe (231) branching off from the first fire extinguishing water supply pipe (230) is connected to the rotation module (220), more specifically the cylinder, and the rod can move in and out by the hydraulic action when a portion of the fire extinguishing water flowing along the first fire extinguishing water supply pipe (230) flows along the branch pipe (231).

[0039] At this time, the flow of the fire extinguishing water through the branch pipe (231) can be controlled by the control unit (500).

[0040] That is, the flow of fire extinguishing water passing through the branch pipe (231) can be controlled by opening and closing a valve (not shown in the drawing) provided in the branch pipe (231) by the control unit (500).

[0041] In addition, in the fire extinguishing water spraying unit (200), at least one of the multiple nozzles (210) is arranged on a drilling member (not shown in the drawing) that moves up and down and rotates by hydraulic pressure, and this drilling member that moves up and down and rotates forms a hole in the bottom of the electric vehicle (symbol omitted in the drawing) where a fire has occurred, so that fire extinguishing water can be sprayed directly onto the battery pack (not shown in the drawing) attached to the bottom of the electric vehicle.

[0042] The first actuation part (300) of the present invention is connected and installed between one end and the other end of the support piece (110) of the support part (100), and has a plurality of wheels (310) on one side that come into contact with the ground.

[0043] Therefore, the rotation of the wheel (310) of the first activation part (300) can activate the fire extinguishing water spraying device (A) activated by water pressure according to the present invention.

[0044] At this time, the wheels (310) of the first actuation part (300) rotate due to the action of water pressure caused by the flow of the fire extinguishing water in the first actuation part (300).

[0045] That is, a water wheel (311) is connected to the rotating shaft (reference numeral omitted) of the wheel (310) of the first starting part (300), and the water wheel (311) rotates due to the hydraulic action of the fire extinguishing water supplied through the second fire extinguishing water supply pipe (330) described later, thereby rotating the wheel (310). Therefore, the fire extinguishing water spraying device (A) activated by water pressure according to the present invention can be started without a separate driving device.

[0046] Meanwhile, the first starting unit (300) includes an outlet (320), and the extinguishing water supplied through the second extinguishing water supply pipe (330) is discharged to the outside through the outlet (320). As the extinguishing water is supplied through the second extinguishing water supply pipe (330), the flow of the extinguishing water continues within the first starting unit (300), thereby allowing the waterwheel (311) and the wheel (310) connected thereto to rotate continuously.

[0047] The second starting part (400) of the present invention is installed between one end and the other end of the support piece (110) of the support part (100) and has a plurality of wheels (410) on one side that come into contact with the ground.

[0048] Therefore, the rotation of the wheel (410) of the second activation part (400) can activate the water pressure activated fire extinguishing water spraying device (A) according to the present invention.

[0049] At this time, the wheels (410) of the second starting part (400) rotate due to the action of water pressure caused by the flow of the fire extinguishing water in the second starting part (400).

[0050] That is, a water wheel (411) is connected to the rotating shaft (reference numeral omitted) of the wheel (410) of the second starting unit (400), and the rotation of the wheel (410) is caused by the rotation of the water wheel (411) due to the hydraulic action of the fire extinguishing water supplied through the third fire extinguishing water supply pipe (430) described later, so that the fire extinguishing water spraying device (A) activated by water pressure according to the present invention can be started without a separate driving device.

[0051] Meanwhile, the second starting unit (400) includes an outlet (420), and the extinguishing water supplied through the third extinguishing water supply pipe (430) is discharged to the outside through the outlet (420). As the extinguishing water is supplied through the third extinguishing water supply pipe (430), the flow of the extinguishing water is continuously performed within the second starting unit (400), thereby allowing the water wheel (411) and the wheel (410) connected thereto to rotate continuously.

[0052] The control unit (500) of the present invention is separated from the support unit (100) and has one end connected to a fire hydrant (symbol omitted in the drawing) and the other end connected to the first fire extinguishing water supply pipe (230) which continues to the fire extinguishing water spray unit (200), the other end connected to the second fire extinguishing water supply pipe (330) which continues to the first starting unit (300), and the other end connected to the third fire extinguishing water supply pipe (430) which continues to the second starting unit (400).

[0053] Therefore, by interrupting the flow of fire extinguishing water by the control unit (500), not only is it possible to prevent unintentional spraying of fire extinguishing water in the fire extinguishing water spray unit (200), but it is also possible to prevent unintentional rotation of the wheels (310) in the first starting unit (300) and the second starting unit (400).

[0054] At this time, the control unit (500) can interrupt the flow of extinguishing water in each of the first extinguishing water supply pipe (230), the second extinguishing water supply pipe (330), and the third extinguishing water supply pipe by opening and closing the valves provided in each of the first extinguishing water supply pipe (230), the second extinguishing water supply pipe (330), and the third extinguishing water supply pipe.

[0055] The control unit (500) may be of any ordinary structure and type as long as it can interrupt the flow of fire extinguishing water in each of the first fire extinguishing water supply pipe (230), the second fire extinguishing water supply pipe (330), and the third fire extinguishing water supply pipe, and therefore a detailed description of the control unit (500) will be omitted.

[0056] In addition, the fire extinguishing water spraying device (A) activated by water pressure according to the present invention may further include a camera (not shown) disposed in either the support part (100) or the fire extinguishing water spraying part (200) and a monitor (not shown) disposed in the control part (500) for displaying images captured by the camera.

[0057] Therefore, when the fire extinguishing water spraying device (A) activated by water pressure according to the present invention moves by remote control to extinguish a fire, it can check the image captured by the camera on the monitor and identify the area in front, especially the source of the fire, and move toward the source of the fire, thereby smoothly spraying fire extinguishing water toward the source of the fire.

[0058] At this time, a monitor (not shown) is provided in the control unit (500), and the images captured by the camera are displayed on the monitor provided in the control unit, allowing the images captured by the camera to be easily checked at the fire extinguishing scene.

[0059] Next, a detailed description will be given of fire extinguishing using the water pressure-activated fire extinguishing water spraying device (A) according to the present invention.

[0060] The present invention includes a fire extinguishing water spraying unit (200) having a plurality of nozzles (210) arranged at intervals on its upper surface, and a first fire extinguishing water supply pipe (230) is connected to one end of the fire extinguishing water spraying unit (200), and fire extinguishing water supplied from the first fire extinguishing water supply pipe (230) flows into the fire extinguishing water spraying unit (200) and can be sprayed to the outside through the plurality of nozzles (210).

[0061] Therefore, the fire is extinguished by discharging the fire extinguishing water through the nozzles (210) of the fire extinguishing water discharge unit (200) toward the vehicle in which the fire has occurred.

[0062] At this time, the fire extinguishing water spraying unit (200) includes a rotation module (220) that is operated by the hydraulic action of the fire extinguishing water supplied through the first fire extinguishing water supply pipe (230), and the operation of the rotation module (220) allows it to rotate forward and backward within a certain angle range and to be able to lay down or stand up, so that fire extinguishing water can be sprayed forward or upward through each nozzle (210).

[0063] That is, the rotation module (220) of the present invention may be a cylinder in which a rod moves in and out due to the hydraulic action of the extinguishing water, as shown in FIG. 6, and by connecting the tip of the rod that moves in and out due to the hydraulic action of the extinguishing water to the extinguishing water spraying part (200), the extinguishing water spraying part (200) can rotate forward and backward within a certain angle range due to the movement of the rod in and out due to the hydraulic action of the extinguishing water.

[0064] Here, a branch pipe (231) branching off from the first fire extinguishing water supply pipe (230) is connected to the cylinder, and the rod can move in and out due to the hydraulic action when a portion of the fire extinguishing water flowing along the first fire extinguishing water supply pipe (230) flows along the branch pipe (231).

[0065] Therefore, when a fire breaks out in a general vehicle (not shown), the fire extinguishing water can be sprayed forward from the front, rear, or side of the general vehicle where the fire has broken out, as shown in FIG. 4, thereby applying the fire extinguishing water to the front, rear, or side of the vehicle, thereby smoothly extinguishing the fire in the general vehicle. In particular, when a fire breaks out in the battery pack of an electric vehicle, the fire extinguishing water can be sprayed upward as shown in FIG. 5 while being placed under the electric vehicle where the fire has broken out, thereby applying the fire extinguishing water in a concentrated manner to the battery pack located at the bottom of the electric vehicle, thereby smoothly extinguishing the fire in the electric vehicle.

[0066] However, the process of extinguishing a fire requires movement, i.e., maneuvering, to approach the vehicle in which the fire has occurred, which can be inconvenient.

[0067] However, the present invention includes a first mobile unit (300) and a second mobile unit (400) each having a plurality of wheels (310, 410) that contact the ground on one side, and as shown in Figure 2, each wheel (310, 410) of the first mobile unit (300) and the second mobile unit (400) rotates in contact with the ground, allowing for easy maneuvering, thereby reducing the hassle of maneuvering.

[0068] At this time, the wheels (310, 410) of the first and second mobile units (300, 400) rotate due to the hydraulic action caused by the internal flow of the extinguishing water supplied through the second and third extinguishing water supply pipes (330, 430). The rotation of the wheels (310, 410) of the first and second mobile units (300, 400) due to the hydraulic action enables mobility without a separate drive device, thereby reducing the complexity and cost associated with preparing a separate drive device for mobility.

[0069] That is, the water wheels (311, 411) are connected to the rotation shafts of the wheels (310, 410) of the first and second moving parts (300, 400), and as shown in FIG. 3, the wheels (310, 410) are rotated by the rotation of the water wheels (311, 411) due to the hydraulic action of the fire extinguishing water supplied through the second and third fire extinguishing water supply pipes (330, 430). Therefore, the fire extinguishing water spraying device (A) activated by water pressure according to the present invention can be started without a separate driving device.

[0070] On the other hand, in the present invention, the flow of extinguishing water in each of the first extinguishing water supply pipe (230) continuing to the extinguishing water spraying unit (200), the second extinguishing water supply pipe (330) continuing from the other end to the first mobile unit (300), and the third extinguishing water supply pipe (430) continuing from the other end to the second mobile unit (400) is controlled by the control unit (500), so that the control of the flow of extinguishing water by the control unit (500) not only prevents unintentional spraying of extinguishing water in the extinguishing water spraying unit (200), but also prevents unintentional rotation of the wheels (310, 410) in the first mobile unit (300) and the second mobile unit (400).

[0071] At this time, the control unit (500) can control the flow of extinguishing water in each of the first extinguishing water supply pipe (230), the second extinguishing water supply pipe (330) and the third extinguishing water supply pipe (430) by opening and closing the valves installed in each of the first extinguishing water supply pipe (230), the second extinguishing water supply pipe (330) and the third extinguishing water supply pipe (430), so that the flow of extinguishing water in each of the first extinguishing water supply pipe (230), the second extinguishing water supply pipe (330) and the third extinguishing water supply pipe (430) can be stably controlled.

[0072] The present invention as described above is not limited to the above embodiments, and modifications can be made without departing from the spirit of the present invention as set forth in the claims, and such modifications are included in the scope of protection of the present invention as defined by the following claims.
