[0023] Please refer to Figure 1 and Figure 2As shown, in one aspect, this utility model embodiment provides a mobile fire extinguishing device for fixing a fire extinguisher. The fire extinguisher includes a cylinder 910, a handle 920, and a nozzle 930. The nozzle 930 is connected to the opening of the cylinder 910, and the handle 920 is adapted to open and close the opening. The mobile fire extinguishing device includes a transport vehicle 100, a cylinder fixing mechanism 200, a nozzle fixing mechanism 300, a handle pressing mechanism 400, and a fire source identification module 500. The cylinder fixing mechanism 200 is connected to the transport vehicle 100. The cylinder fixing mechanism 200 includes a cylinder fixing seat 210 and a cylinder fixing member 220. The cylinder fixing seat 210 is provided with a cylinder limiting groove 211. The cylinder 910 is pre-positioned in the cylinder limiting groove 211. The cylinder fixing member 220 is adapted to switch between a locked state and an unlocked state. The cylinder 910 is in the state where the cylinder fixing member 220 fixes the cylinder 910, and the unlocked state is when the cylinder fixing member 220 releases the cylinder 910 from the cylinder limiting groove 211. The nozzle fixing mechanism 300 is connected to the carrier vehicle 100, and the nozzle fixing mechanism 300 is detachably connected to the nozzle 930. The pressure lever pressing mechanism 400 is connected to the carrier vehicle 100. The pressure lever pressing mechanism 400 includes a pressing drive member 410 and a pressing part 420. The pressing part 420 can press the pressure lever 920 under the drive of the pressing drive member 410 to switch the opening and closing state of the cylinder 910. The fire source identification module 500 is connected to the carrier vehicle 100. The fire source identification module 500 is suitable for identifying fire sources. The fire source identification module 500 is communicatively connected to the pressing drive member 410.

[0024] According to the mobile fire extinguishing device of this utility model embodiment, when there is a fire extinguishing need, the operator places the fire extinguisher in the cylinder limiting groove 211 for pre-positioning, switches the cylinder fixing member 220 to the locked state to fix the cylinder 910 of the fire extinguisher, then fixes the nozzle 930 to the nozzle fixing mechanism 300, starts the transport vehicle 100 to transport the fire extinguisher to the vicinity of the fire source, the fire source identification module 500 identifies the fire source and sends an identification signal and triggers the pressure driving member 410 to drive the pressure part 420 to move, the pressure part 420 presses against the handle 920, so that the opening of the cylinder 910 is opened, and the fire extinguishing agent in the cylinder 910 is sprayed out from the nozzle 930 to the fire source.

[0025] It should be noted that the batteries of new energy vehicles are highly susceptible to fire upon impact, and manual firefighting is extremely dangerous, as extinguishing agents often fail to reach the battery area, making effective fire control difficult. To address this, existing technologies propose mobile fire extinguishing devices. These devices utilize a mobile cart carrying extinguishing agents and a fire source identification module 500 on the cart to identify the fire source for targeted suppression. However, the extinguishing agents in this solution are typically pre-stored in tanks on the mobile cart, requiring frequent replenishment. This results in poor timeliness and effectiveness in extinguishing sudden fires (such as those involving new energy vehicles).

[0026] According to the embodiments of the present invention, the mobile fire extinguishing device, by detachably connecting the fire extinguisher to the transport vehicle 100, greatly improves the efficiency of fire extinguishing agent replenishment, and enhances the timeliness and effectiveness of fire extinguishing. Furthermore, using the transport vehicle 100 to transport the fire extinguisher keeps operators away from the fire source, significantly improving operator safety, especially when facing a fire source with a potential explosion risk. Simultaneously, the fire source identification module 500 on the transport vehicle 100, in conjunction with the pressure handle mechanism 400, allows the cylinder 910 to open only when a fire source is detected, effectively reducing the waste of fire extinguishing agent in the cylinder 910 and extending the range of a single fire extinguishing cycle of the mobile fire extinguishing device.

[0027] In this embodiment, the transport vehicle 100 can be a Bluetooth remote-controlled vehicle that can be operated by an operator to move to the vicinity of the fire source, or it can be an automatic obstacle avoidance vehicle that uses ultrasonic modules, infrared sensing modules, image recognition modules, etc. carried by the automatic obstacle avoidance vehicle itself to enable the transport vehicle 100 to move automatically to the vicinity of the fire source.

[0028] In this embodiment, the communication connection between the fire source identification module 500 and the pressure drive 410 can be in the form of a controller (such as a microcontroller). The detection result of the fire source identification module 500 is in the form of a high level (fire source identified) and a low level (fire source not identified). The pressure drive 410 can move forward based on the high level signal and retreat based on the low level signal.

[0029] In this embodiment, the pressing drive 410 can be a motor, cylinder, lead screw module, slide module, etc., to realize the movement of the pressing part 420 and the pressing handle 920.

[0030] In this embodiment, the cylinder fixing seat 210 is provided with two cylinder limiting grooves 211, each cylinder limiting groove 211 can hold a fire extinguisher. Of course, the number of cylinder limiting grooves 211 can be adjusted based on the actual carrying capacity of the transport vehicle 100 and the volume adaptability of the cylinder fixing seat 210.

[0031] In some embodiments, combined with Figure 1 As shown, the cylinder fixing base 210 includes a support plate assembly, which includes multiple support plates 212. These support plates 212 are sequentially arranged along the cylinder fixing mechanism 200 towards the nozzle fixing mechanism 300. The edges of the support plates 212 are recessed towards their centers to form limiting notches 2121. These limiting notches 2121 constitute a cylinder limiting groove 211. By using multiple support plates 212 for support, the structural volume required to form the cylinder limiting groove 211 is reduced, significantly reducing the load on the transport vehicle 100 and correspondingly increasing the load capacity (number or weight) of the fire extinguisher.

[0032] In this embodiment, multiple support plates 212 are placed horizontally to form a horizontally extending cylinder limiting groove 211. Of course, multiple support plates 212 can also be placed vertically to form a vertically extending cylinder limiting groove 211.

[0033] In this embodiment, the support plate assembly includes two support plates 212, each of which has two limiting notches 2121. The limiting notches 2121 on different support plates 212 together constitute the cylinder limiting groove 211. Of course, the number of limiting notches 2121 on a single support plate 212 can be adjusted based on the actual fire extinguisher placement requirements.

[0034] In some embodiments, combined with Figure 1 As shown, the surface of the support plate 212 is perpendicular to the horizontal direction (XY plane), and multiple support plates 212 are parallel to each other; this facilitates the formation of a horizontally placed cylinder limiting groove 211, lowers the overall center of gravity of the mobile fire extinguishing device, and improves the stability of movement.

[0035] In this embodiment, combined with Figure 1 and Figure 3 As shown, the cylinder fixing component 220 includes a pressure cap 221, which is detachably connected to the cylinder fixing seat 210. The pressure cap 221 covers the cylinder fixing seat 210 to prevent the cylinder 910 from disengaging from the cylinder limiting groove 211. The cylinder 910 is fixed by the pressure of the pressure cap 221, and during fire extinguishing, the pressure cap 221 can effectively isolate the heat of the fire source, ensuring the operational stability of the mobile fire extinguishing device. The detachable connection between the pressure cap 221 and the cylinder fixing seat 210 can be a snap-fit ​​connection, a bolt connection, a magnetic connection, etc.

[0036] In this embodiment, combined with Figure 1 and Figure 3 As shown, the cylinder fixing component 220 also includes an electromagnet 222. The bottom edge of the limiting notch 2121 is arc-shaped. The horizontal height of the top of the electromagnet 222 in the vertical direction is less than or equal to the horizontal height of the bottom of the limiting notch 2121. In the locked state, the electromagnet 222 is energized to attract the cylinder 910. In the unlocked state, the electromagnet 222 is de-energized.

[0037] In this embodiment, the arc-shaped limiting notch 2121 ensures that any fire extinguisher with a diameter smaller than the opening of the limiting notch 2121, when placed in the cylinder limiting groove 211 formed by the limiting notch 2121, will move to the bottom of the limiting notch 2121 and be fixed in place by generating a magnetic force through energizing the electromagnet 222. This allows the portable fire extinguishing device of this application to be adapted to fix fire extinguishers of different diameters, greatly improving the adaptability of the portable fire extinguishing device.

[0038] In other embodiments, the cylinder fastener 220 can also be a physical form, such as using a bandage, pressure plate, etc.

[0039] In this embodiment, the electromagnet 222 can be switched on and off by setting an independent switch, such as setting an on / off button for manual operation. Alternatively, a pressure sensor can be set to detect whether the cylinder fixing seat 210 is carrying the fire extinguisher, and the electromagnet 222 can be switched on and off based on the detection result.

[0040] In some embodiments, combined with Figure 1 As shown, the cylinder fixing mechanism 200 also includes a pressure handle positioning component 230. The pressure handle positioning component 230 is connected to one end of the cylinder fixing base 210 near the nozzle fixing mechanism 300. The pressure handle positioning component 230 includes two pressure handle positioning plates 231 arranged opposite to each other. A pressure handle positioning groove is formed between the two pressure handle positioning plates 231. The extending direction of the pressure handle positioning groove is the same as the direction from the bottom of the cylinder limiting groove 211 to the opening of the groove.

[0041] In this embodiment, while the cylinder 910 is placed in the cylinder limiting groove 211, the handle 920 enters the handle positioning groove. The handle positioning groove ensures that the angle of each fire extinguisher is basically the same when it is placed, which makes it easier for the nozzle fixing mechanism 300 to fix the nozzle 930.

[0042] In some embodiments, combined with Figure 1 As shown, the pressure handle positioning plate 231 has an observation hole 2311, and the observation area of ​​the observation hole 2311 covers at least part of the movement path of the pressure handle 920. By observing through the observation hole 2311 whether the pressing part 420 moves normally to press the pressure handle 920, it is convenient to check for abnormal functions of related components during the pressing of the pressure handle pressing mechanism 400 to the pressure handle 920.

[0043] In some embodiments, combined with Figure 1 and Figure 2 As shown, the nozzle fixing mechanism 300 includes a support column 310, a reduction motor 320, and an extension tube 330. The reduction motor 320 is connected to the transport vehicle 100 through the support column 310. The extension tube 330 is connected to the output shaft of the reduction motor 320. The axis of the extension tube 330 is perpendicular to the axis of the output shaft of the reduction motor 320. The first end of the extension tube 330 is detachably connected to the nozzle 930, and the second end of the extension tube 330 is provided with a nozzle. The reduction motor 320 is communicatively connected to the fire source identification module 500.

[0044] In this embodiment, the operator fixes the cylinder 910 to the cylinder limiting groove 211 and connects the nozzle 930 to the first end of the extension tube 330. When the mobile fire extinguishing device moves to the fire source identification module 500 and identifies the location of the fire source, the fire source identification module 500 triggers the pressure drive 410 and the reduction motor 320. The reduction motor 320 drives the extension tube 330 to rotate to adjust the nozzle angle and height. The fire extinguishing agent in the cylinder 910 flows through the nozzle 930 and the extension tube 330 and is sprayed from the nozzle to the fire source.

[0045] In this embodiment, the extension tube 330 expands the spray angle and height of the extinguishing agent, adapting to more fire source locations, and in conjunction with the reduction motor 320, increases the output torque, making it easier to drive the extension tube 330 to rotate; when not in use, the extension tube 330 can be stored parallel to the cylinder 910, reducing the space required to place the mobile fire extinguishing device.

[0046] In this embodiment, the communication connection between the geared motor 320 and the fire source identification module 500 is the same as the communication connection between the fire source identification module 500 and the pressure drive component 410 described above, and will not be repeated here.

[0047] In some embodiments, combined with Figure 1 and Figure 2 As shown, the nozzle fixing mechanism 300 also includes a position detection component 340. The output shaft of the reduction motor 320 is provided with a trigger part 321 that rotates with the output shaft. The trigger area of ​​the position detection component 340 is located within the stroke range of the trigger part 321. The position detection component 340 is communicatively connected to the reduction motor 320.

[0048] In this embodiment, the output shaft of the reduction motor 320 synchronously drives the extension tube 330 and the trigger part 321 to rotate. When the trigger part 321 rotates to the trigger area of ​​the position detection element 340, the position detection element 340 triggers the reduction motor 320 to stop, thereby stopping the rotation of the extension tube 330. By setting the positional relationship between the position detection element 340 and the trigger part 321, the reduction motor 320 can be stopped when the extension tube 330 rotates to the required angle, thus adjusting the position of the extension tube 330 while preventing the extension tube 330 from overtraveling.

[0049] In this embodiment, the communication connection between the position detection component 340 and the reduction motor 320 can be referred to the communication connection between the fire source identification module 500 and the pressure drive component 410 described above, and will not be repeated here.

[0050] In this embodiment, two coaxially arranged output shafts extend from both sides of the geared motor 320. Each output shaft is provided with a trigger part 321, and the two trigger parts 321 are located at different positions in the circumferential direction of the output shaft. A position detection element 340 is provided below each trigger part 321. The two trigger parts 321 correspond to the extension tube 330 being in a horizontal position and a vertical position, respectively. Of course, more trigger parts 321 can be provided to correspond to various angles based on the angle that the extension tube 330 needs to be adjusted.

[0051] In this embodiment, the trigger part 321 is a screw, and the position detection element 340 is a limit switch; in other embodiments, the position detection element 340 may also be a photoelectric switch (the trigger part 321 corresponds to a light shield), a pressure sensor (the trigger part 321 is the physical structure of a pressure sensor, such as a screw), etc.

[0052] In some embodiments, combined with Figure 3 As shown, the fire source identification module 500 includes at least one of a vision camera 510, a millimeter-wave radar (not shown in the figure), and an infrared temperature sensor (not shown in the figure).

[0053] In this embodiment, the visual camera 510 can not only be used to identify the fire source, but also record the entire fire extinguishing process in real time. When the visual camera 510 is connected to the operator's terminal (mobile phone, remote sensing, etc.), it can transmit image information of the location of the mobile fire extinguishing device in real time, which is convenient for the operator to move the transport vehicle 100.

[0054] In this embodiment, although millimeter-wave radar cannot directly "see" the fire source, it can detect strongly moving targets driven by hot air currents near the fire source (such as flying burning debris, ash, and violently disturbed smoke particles). By identifying these abnormal movement areas and their movement vectors (velocity and direction), combined with changes in radar echo intensity, the approximate location and spread direction of the fire source or high-temperature core area can be indirectly inferred. Furthermore, millimeter-wave radar can effectively penetrate media such as dense smoke and water vapor, and can work continuously in environments with extremely low visibility, detecting the location and outline of static obstacles at the fire scene in real time, constructing a spatial map of the fire scene, and improving the mobility efficiency of the transport vehicle 100.

[0055] In this embodiment, the infrared temperature sensor can quickly identify the high-temperature area where the fire source is located.

[0056] The above, combined with a vision camera 510, millimeter-wave radar and infrared temperature sensor, can form a mobile fire extinguishing device that can move in environments with extremely low visibility, quickly identify the location of the fire source, and record the fire extinguishing process.

[0057] In some embodiments, combined with Figure 3As shown, the mobile fire extinguishing device also includes a fireproof cover 600, which is connected to the top of the transport vehicle 100, and the edge of the fireproof cover 600 extends downward to cover the skirt of the transport vehicle 100. The fireproof cover 600 can reduce the heat transferred from the fire source to the transport vehicle 100, ensuring the stable operation and service life of the transport vehicle 100. Especially when the transport vehicle 100 uses pneumatic tires, it can effectively reduce the risk of tire blowout.

[0058] Furthermore, the aforementioned millimeter-wave radar, infrared temperature sensor, controller, etc., can be installed inside the fireproof cover 600 to reduce their own temperature and improve operational stability.

[0059] In some embodiments, the transport vehicle 100 is a tracked vehicle. Compared to the transport vehicle 100 with pneumatic tires, the tracked vehicle has advantages such as superior chassis passability to adapt to complex terrain, a larger ground contact area to distribute loads and improve load capacity, and high temperature resistance without the risk of tire blowout.

[0060] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
