[0032] When a fire breaks out at the bottom of a vehicle, it is difficult for fire hoses to directly spray water onto the chassis, making cooling and fire control challenging. Therefore, this embodiment provides a vehicle fire extinguishing device, such as... Figures 1 to 4 As shown, it includes a liquid supply device 1 and a first liquid outlet device 2 disposed on the liquid supply device 1. The liquid supply device 1 and the first liquid outlet device 2 are connected. The first liquid outlet device 2 is used to extend into the vehicle chassis under the drive of the liquid supply device 1 and receive the liquid supplied by the liquid supply device 1 to output liquid flow to the vehicle chassis. The first liquid outlet device 2 has a first liquid outlet area 211 and a second liquid outlet area 221. The liquid flow shapes output by the first liquid outlet area 211 and the second liquid outlet area 221 are different.

[0033] The vehicle fire extinguishing device provided in this embodiment can extend into the vehicle chassis, quickly reach the fire location under the chassis, and directly spray the fire source beneath the chassis. This device can accurately locate the fire source, allowing the extinguishing liquid to more effectively cover it, improving extinguishing efficiency, reducing extinguishing time and liquid consumption, thereby reducing damage to the vehicle chassis and surrounding components and lowering maintenance costs. Furthermore, the vehicle fire extinguishing device can flexibly extend into the chassis of different vehicles, making it widely applicable to various vehicles, demonstrating strong practicality and versatility.

[0034] The vehicle fire extinguishing device provided in this embodiment can output liquid streams of different shapes through the first liquid outlet area 211 and the second liquid outlet area 221, achieving different fire extinguishing effects. It can more effectively reduce the temperature of the fire source, isolate oxygen, and disrupt combustion conditions. Furthermore, this embodiment can output liquid streams of different shapes, adapting to the constantly changing location, size, and shape of the fire source during actual fire extinguishing, demonstrating strong adaptability.

[0035] like Figures 1 to 4 As shown, in one embodiment, the first liquid outlet device 2 includes a frame-shaped body 21 and a first strip-shaped body 22. The first strip-shaped body 22 is disposed on the frame-shaped body 21, and a first liquid outlet area 211 is formed on the frame-shaped body 21. A second liquid outlet area 221 is formed on the first strip-shaped body 22. The frame-shaped body 21 is composed of a plurality of second strip-shaped bodies 212 arranged sequentially, wherein each of two opposing second strip-shaped bodies 212 is provided with one or more first strip-shaped bodies 22.

[0036] In this embodiment, a first strip 22 is provided on both opposite sides of the frame 21, and a second liquid outlet area 221 is provided on both opposite sides of the first liquid outlet area 211, so that the extinguishing liquid is sprayed from multiple directions at the same time, thereby greatly increasing the coverage of the fire extinguishing.

[0037] Furthermore, by simultaneously spraying extinguishing liquid from multiple outlet areas, this embodiment can reduce the temperature around the fire source more quickly, disrupt combustion conditions more rapidly, reduce the possibility of fire spread, and improve extinguishing efficiency.

[0038] Furthermore, this embodiment is particularly suitable for situations where there are multiple fire sources under the vehicle chassis or where the location of the fire sources is uncertain. This embodiment can ensure that the extinguishing liquid covers all possible fire sources, thereby improving the fire extinguishing effect.

[0039] In one embodiment, the frame 21 and the first strip 22 are integrally formed.

[0040] In one embodiment, there are four second strips 212, which are arranged sequentially to form a quadrilateral frame 21, wherein each of the two opposite second strips 212 is provided with one or more first strips 22.

[0041] like Figures 1 to 4 As shown, in one embodiment, a plurality of circular through holes 2111 are provided on the second strip body 212. The plurality of circular through holes 2111 are arranged sequentially along the length direction of the second strip body 212. The circular through holes 2111 on each second strip body 212 constitute a first liquid outlet region 211, so that the first liquid outlet region 211 outputs a columnar liquid flow with a circular cross section.

[0042] The first liquid outlet region 211 in this embodiment has a clear spray direction and a concentrated spray range, enabling it to act more precisely on the ignition source. The cylindrical liquid stream with a circular cross-section has strong penetrating power, allowing it to quickly penetrate the flame and directly act on the burning material.

[0043] like Figures 1 to 4As shown, in one embodiment, a plurality of strip-shaped through holes 2211 are provided on the first strip body 22. The plurality of strip-shaped through holes 2211 are arranged sequentially along the length direction of the first strip body 22. The plurality of strip-shaped through holes 2211 constitute a second liquid outlet region 221, so that the second liquid outlet region 221 outputs a columnar liquid flow with a strip-shaped cross section.

[0044] The second liquid outlet area 221 in this embodiment can increase the spray range and cover a larger fire source area. Furthermore, the second liquid outlet area 221 is particularly suitable for extinguishing long or linear fire sources, as it can spray along the length of the fire source, achieving effective flame extinguishing.

[0045] like Figures 1 to 4 As shown, in one embodiment, the vehicle fire extinguishing device further includes a three-way pipe 7, which has a first input end 71, a second input end 72 and an output end 73. The first input end 71 is used to input fire water, the second input end 72 is used to input fire water containing abrasive, and the output end 73 is connected to the end of the first liquid supply device 1 that is away from the first liquid outlet device 2.

[0046] In this embodiment, by setting a three-way pipe 7, fire water source and fire water source containing abrasive can be introduced at the same time. The abrasive increases the cutting force and penetrating force of the water flow, which helps the fire extinguishing liquid penetrate the flame more quickly and destroy the combustion conditions.

[0047] like Figures 1 to 4 As shown, in one embodiment, the vehicle fire extinguishing device further includes a second liquid dispensing device 6, and the output terminal 73 of the liquid supply device 1 is connected to the first liquid dispensing device 2 and the second liquid dispensing device 6 respectively. This embodiment, by providing the second liquid dispensing device 6, enables the vehicle fire extinguishing device to be flexibly adjusted according to the actual fire situation, improving the flexibility of fire extinguishing.

[0048] Specifically, the second liquid outlet device 6 includes, but is not limited to, an ultra-high pressure spray gun.

[0049] like Figures 1 to 4 As shown, in one embodiment, the output end 73 of the liquid supply device 1 is detachably connected to the first liquid dispensing device 2 via a first connecting structure 3. This embodiment facilitates the rapid transfer and deployment of the vehicle fire extinguishing device between different locations by allowing the industrial device and the first liquid dispensing device to be detachably connected. It also facilitates replacement and maintenance.

[0050] Specifically, the first connecting structure 3 includes a snap-fit ​​connecting structure, but is not limited to this.

[0051] like Figures 1 to 4As shown, in one embodiment, the liquid supply device 1 includes two or more sub-liquid supply devices 11, which are arranged sequentially, and adjacent sub-liquid supply devices 11 are detachably connected through a second connection structure 4.

[0052] In this embodiment, the liquid supply device 1 is divided into multiple sub-liquid supply devices 11. Each sub-liquid supply device 11 is an independent module, and adjacent sub-liquid supply devices 11 are detachably connected, allowing the user to increase or decrease the number of sub-liquid supply devices 11 according to actual needs. For example, when the firefighting task increases or the firefighting area expands, new sub-liquid supply devices 11 can be added to expand the capacity and coverage of the vehicle fire extinguishing system. Furthermore, dividing the liquid supply device 1 into multiple sub-liquid supply devices 11 can reduce the size and weight of individual components, thereby facilitating transportation and installation.

[0053] Specifically, the second connecting structure 4 includes, but is not limited to, a snap-fit ​​connecting structure.

[0054] like Figures 1 to 4 As shown, in one embodiment, a control device 5 is provided on the sub-liquid supply device 11 located at the first end. The control device 5 is used to control the opening and closing of the pipeline of the sub-liquid supply device 11 located at the first end. This embodiment enables the operator to quickly cut off or open the pipeline of the sub-liquid supply device 11 at the first end through the control device 5 in case of emergency, such as in the event of a fire, so as to respond quickly to changes in the fire situation.

[0055] In one embodiment, the sub-liquid supply device 11 located at the end is connected to the first liquid outlet device 2.

[0056] like Figures 1 to 4 As shown, in one embodiment, the length of the sub-liquid supply device 11 is between 0.5m and 2m. This embodiment makes the length of the sub-liquid supply device 11 between 0.5m and 2m, which facilitates the transportation of the sub-liquid supply device 11 and also makes it easier for the user to assemble the sub-liquid supply device 11.
