This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Figure 1 This is a side view of a mobile vehicle fire-fighting spray device 1000 according to an embodiment of this application. Figure 2 This is a partial enlarged view of a mobile vehicle fire-fighting spray device 1000 according to an embodiment of this application.

[0025] refer to Figure 1 and Figure 2The mobile vehicle-mounted fire-fighting spray device 1000 includes a mobile trolley 1100. Preferably, the mobile trolley 1100 is equipped with drive wheels and a steering mechanism, enabling it to autonomously move to a predetermined working position near the burning vehicle. The proximal end of the telescopic assembly 1200 is hinged to the mobile trolley 1100, allowing the telescopic assembly 1200 to adjust its pitch within a certain angle range and adapt to fire points at different heights and positions. A first lead screw 1310 is provided on the telescopic assembly 1200, and a first slider 1320 is threadedly connected to the first lead screw 1310. The proximal end of a first connecting rod 1330 is hinged to the first slider 1320, and a second lead screw 1410 is provided on the first connecting rod 1330, with the second slider 1420 threadedly connected to the second lead screw 1410. The spray head 1510 of the air supply pipe 1500 is drivenly connected to the second slider 1420 to achieve position control.

[0026] Preferably, the air supply duct 1500 can be made of metal flexible hose or segmented telescopic composite material pipe, so that the air supply duct 1500 can flexibly switch between extended and retracted states to adapt to the fire extinguishing needs of different distances and complex spaces.

[0027] Preferably, the first lead screw 1310 is connected to a first drive motor (not shown in the figure) for driving the first lead screw 1310 to rotate in both directions, thereby causing the first slider 1320 to move along the axial direction of the first lead screw 1310. Similarly, the second lead screw 1410 is connected to a second drive motor (not shown in the figure) for driving the second lead screw 1410 to rotate in both directions, thereby causing the second slider 1420 to move along the axial direction of the second lead screw 1410. Further, the first drive motor and the second drive motor can be stepper motors or servo motors.

[0028] Through the aforementioned transmission structure, when the first slider 1320 moves along the first lead screw 1310, it will drive the first connecting rod 1330 and the second lead screw 1410 mounted thereon to move as a whole; at the same time, the second slider 1420 moves along the second lead screw 1410 to further adjust the position of the spray head 1510, thereby realizing the multi-degree-of-freedom positioning of the spray head 1510 in the two-dimensional plane, and realizing the spraying of fire extinguishing materials onto the burning vehicle.

[0029] To further improve the directional adaptability of the mobile vehicle fire-fighting spray device 1000, the mobile vehicle fire-fighting spray device 1000 also includes a rotating mechanism 1440, which is located at the distal end of the first connecting rod 1330. A second lead screw 1410 is mounted on the rotating mechanism 1440 and can rotate about a vertical axis in the horizontal plane. Therefore, the spray head 1510 can rotate horizontally, expanding its coverage area.

[0030] In one embodiment of this application, the first slider 1320 is initially located at the middle position of the first lead screw 1310. When the first slider 1320 moves along the first axis, it drives the rotary mechanism 1440 to rotate via the first connecting rod 1330, thereby causing the spray head 1510 to deflect in a second axis direction perpendicular to the first axis. Conversely, when the first slider 1320 moves in the opposite direction to the first axis, the spray head 1510 deflects in the opposite direction to the second axis.

[0031] Furthermore, the mobile vehicle fire-fighting spray device 1000 is also equipped with a second connecting rod 1430. The proximal end of the second connecting rod 1430 is hinged to the second slider 1420, and the distal end is hinged to the spray head 1510 of the air supply pipe 1500. When the second slider 1420 moves along the second lead screw 1410, the second connecting rod 1430 pushes or pulls the spray head 1510, thereby adjusting its pitch angle.

[0032] Specifically, the second slider 1420 is initially located at the middle position of the second lead screw 1410. When the second slider 1420 moves along the first axis, the injection head 1510 rises. Conversely, when the second slider 1420 moves in the opposite direction along the first axis, the injection head 1510 lowers.

[0033] Figure 3 This is a structural diagram of the mobile vehicle fire-fighting spray device 1000 in the hidden storage tank 1700 state.

[0034] refer to Figure 2 and Figure 3 The telescopic assembly 1200 also includes a fixed rail 1210 and a sliding rail 1220. The near end of the fixed rail 1210 is hinged to the moving trolley 1100, and the sliding rail 1220 is nested within the fixed rail 1210 and can slide along its axial direction. The first lead screw 1310 is fixedly mounted on the sliding rail 1220. The extension and retraction of the sliding rail 1220 can drive the air supply pipe 1500 and the nozzle 1510 to extend or retract as a whole, adapting to different fire conditions at near and far distances.

[0035] Furthermore, a telescopic drive motor is provided between the sliding rail 1220 and the fixed rail 1210 to drive the sliding rail 1220 to extend or retract relative to the fixed rail 1210. The telescopic drive motor can be a hydraulic cylinder or an electric push rod.

[0036] Specifically, as the sliding rail 1220 slides along the first axis, the air supply pipe 1500 extends, and the nozzle 1510 covers the far end of the moving trolley 1100. Conversely, as the sliding rail 1220 slides in the opposite direction along the first axis, the air supply pipe 1500 retracts, and the nozzle 1510 covers the near end of the moving trolley 1100.

[0037] To ensure that the mobile vehicle fire-fighting spray device 1000 can meet the fire-fighting needs of vehicles burning at different heights, the mobile vehicle fire-fighting spray device 1000 is also equipped with a lifting arm 1600. The proximal end of the lifting arm 1600 is hinged to the mobile trolley 1100, and the distal end is hinged to the distal end of the fixed rail 1210. Furthermore, the lifting arm 1600 is driven by a hydraulic cylinder or an electric push rod, which can achieve smooth lifting and lowering, thereby enabling the telescopic assembly 1200 and the air supply pipe 1500 to make a wide range of adjustments in vertical height.

[0038] Specifically, the mobile vehicle fire-fighting spray device 1000 is particularly suitable for scenarios with limited space and complex structures, such as garages. In the non-working state, the lifting arm 1600 can be fully retracted, allowing the air supply pipe 1500 and the spray head 1510 to be retracted above the mobile trolley 1100, thereby significantly reducing the overall size and facilitating movement and parking in limited spaces.

[0039] According to this application, the mobile vehicle fire-fighting spray device 1000 also includes a storage tank 1700, which stores fire extinguishing materials. Given that the power of new energy vehicles is mainly provided by ternary lithium batteries and lithium iron phosphate batteries, these batteries have a high risk of reignition and are difficult to extinguish after catching fire. Therefore, the fire extinguishing material is preferably a high-molecular organic foam developed specifically for lithium-ion battery fires. This high-molecular organic foam has high heat insulation and high adhesion, and can quickly cover the surface of the battery pack, effectively isolating oxygen and terminating the chain chemical reaction.

[0040] Furthermore, the nozzle 1510 is connected to the storage tank 1700 via the transmission pipe 1800 to ensure that the extinguishing material can be stably delivered to the nozzle 1510.

[0041] The mobile vehicle fire-fighting spray device 1000 also includes a fan 1900, with the near end of the air supply duct 1500 fixedly connected to the fan 1900. Furthermore, the ventilation opening of the fan 1900 is located at the bottom of the mobile trolley 1100.

[0042] Preferably, the fans 1900 can be installed on both sides of the bottom of the mobile trolley 1100, with their openings facing vertically downwards. This design forms an effective dustproof structure, significantly reducing the risk of ground dust, fire-borne particles, and liquids (such as fire extinguishing foam) being sucked into the air supply duct 1500.

[0043] Furthermore, a filter screen can be integrated inside the ventilation opening of the 1900 fan to ensure a continuous supply of clean airflow to the internal drive motor, thereby ensuring the equipment can operate stably for a long time in high-temperature and high-dust environments.

[0044] In one embodiment of this application, while the high-speed airflow generated by the fan 1900 is delivered through the air supply pipe 1500, the fire extinguishing material is delivered to the nozzle 1510 through the transmission pipe 1800. With the help of the airflow, the material is sprayed to the fire source, achieving a long-distance and high-efficiency fire extinguishing effect.
