Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing technology, and in particular to a fire extinguishing device for new energy vehicles in underground garages. Background Technology

[0002] Fires in new energy vehicles are typically caused by short circuits due to external impacts, or thermal runaway due to overcharging or overheating. The electrolyte inside the battery decomposes, producing a large amount of gas. When the internal gas pressure reaches a certain level and breaches the battery pack casing, the electrolyte gas is released at an extremely high speed and explodes upon contact with oxygen. Battery fires usually occur rapidly, burning and exploding within tens of seconds or even a few seconds, producing large amounts of dense smoke and toxic gases.

[0003] Because underground parking garages have a single-lane width of 3-3.8 meters, a net height of 2.2-2.5 meters, and a minimum turning radius of 6.0 meters for driveways, they can only be used for small vehicles for rescue. Currently available equipment is limited by space and has difficulty entering underground parking garages to extinguish fires. In addition, battery fires produce a lot of dense smoke. Therefore, there is an urgent need to design a new energy vehicle fire extinguishing device for underground parking garages to address the special fire environment. Utility Model Content

[0010] Preferably, the guide rail frame is installed on the outer peripheral wall of the rotating ring. The guide rail frame includes a fixed rail plate, a middle rail plate, and an end rail plate. The fixed rail plate is fixedly installed on the outer peripheral wall of the rotating ring. The middle rail plate is installed in the rail groove of the fixed rail plate. The end rail plate is installed in the rail groove of the middle rail plate. Adaptive rails are provided on both sides of the middle rail plate and the end rail plate. The drive wheels installed at the ends of the rail grooves of the fixed rail plate and the middle rail plate can change the horizontal position of the middle rail plate and the end rail plate by rotation, thereby realizing the extension and retraction of the guide rail frame.

[0011] Preferably, the retraction assembly includes two autonomous moving blocks and a central support rod and a tail support rod respectively mounted on the autonomous moving blocks.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Example 1

[0025] Reference Figure 1-4The fire extinguishing device for new energy vehicles in underground parking garages includes a smoke exhaust assembly 1 and a fire extinguishing assembly 2 installed on the body of an off-road vehicle 500. The smoke exhaust assembly 1 includes a smoke exhaust fan 11 installed at the front of the front of the off-road vehicle 500 and a smoke exhaust pump 12 installed in the rear compartment. The front of the off-road vehicle 500 is also equipped with a thermal imaging camera 3. When heading to a fire scene, firefighters can drive to the burning vehicle under the guidance of the thermal imaging camera 3. During the advance, the smoke exhaust fan 11 can draw out the dense smoke in front of the vehicle and exhaust it to the rear of the vehicle to maintain a clear view for the driver.

[0026] The fire extinguishing assembly 2 includes a rotating platform 21, a spraying device 22, and a guide rail frame 23 installed on the roof of the cab of the off-road vehicle 500. The rotating platform 21 includes a fixed base 211 and a rotating ring 212. The fixed base 211 is fixedly installed on the roof of the cab of the off-road vehicle 500. A mounting base 213 is fixedly installed on the top of the fixed base 211. The rotating ring 212 is installed around the mounting base 213. A rotating wheel driven by a motor is provided on the outer peripheral wall of the mounting base 213. The inner peripheral wall of the rotating ring 212 has an annular groove that is just enough for the rotating wheel to be inserted, so that the rotating wheel rotating in the annular groove can also drive the rotating ring 212 to rotate axially.

[0027] The outer periphery of the rotating ring 212 is symmetrically provided with a liquid inlet connector 221 and a telescopic spray pipe 222. A pipe is installed inside the rotating ring 212 to connect the liquid inlet connector 221 and the telescopic spray pipe 222. A liquid supply connector 223 is installed on the rotating platform 21 facing the rear compartment. The liquid supply connector 223 is installed on a lifting seat 225 controlled by a translation push rod 224. The translation push rod 224 controls the lifting seat 225 to move towards or away from the rotating platform 21. The lifting seat 225 can drive the liquid supply connector 223 installed on it to move vertically up and down. The liquid supply connector 223 is connected to a perfluoroethyl ketone (PFO) fire extinguishing agent tank installed inside the rear compartment. The rotating ring 212 is in a forward position... Normally, the telescopic spray pipe 222 faces the rear of the vehicle while the liquid supply connector 223 faces the front. At this time, the lifting seat 225 lowers so that the liquid supply connector 223 is below the telescopic spray pipe 222. During fire extinguishing operations, the rotating ring 212 rotates the telescopic spray pipe 222 to the front of the vehicle. The lifting seat 225 rises so that the liquid supply connector 223 is at the same height as the liquid inlet connector 221. Then, the translation push rod 224 pushes the lifting seat 225 toward the rotating platform 21 so that the liquid supply connector 223 aligns with the liquid inlet connector 221. In this way, the extinguishing agent in the perfluoroethyl ketone extinguishing agent tank can be pumped to the telescopic spray pipe 222, thereby spraying the extinguishing agent onto the burning vehicle to extinguish the fire.

[0028] Example 2

[0029] Reference Figure 1-4The difference between this embodiment and Embodiment 1 is that the guide rail frame 23 is installed on the outer peripheral wall of the rotating ring 212. The guide rail frame 23 includes a fixed rail plate 231, a middle rail plate 232, and an end rail plate 233. The fixed rail plate 231 is fixedly installed on the outer peripheral wall of the rotating ring 212. The middle rail plate 232 is installed in the rail groove of the fixed rail plate 231. The end rail plate 233 is installed in the rail groove of the middle rail plate 232. Adaptive tracks are provided on both sides of the middle rail plate 232 and the end rail plate 233. The drive wheels installed at the ends of the rail grooves of the fixed rail plate 231 and the middle rail plate 232 can change the horizontal position of the middle rail plate 232 and the end rail plate 233 by rotation, thereby realizing the extension and retraction of the guide rail frame 23. The telescopic spray pipe 222 is located below the guide rail frame 23, and its end is connected to the end rail plate 233 so that the telescopic spray pipe 222 can extend and retract synchronously with the guide rail frame 23.

[0030] The upper surface of the mounting base 213 is provided with a docking rail groove 201. A retraction assembly 24 is installed in the docking rail groove 201. The retraction assembly 24 includes two autonomous moving blocks 241 and a central support rod 242 and a tail support rod 243 respectively installed on the autonomous moving blocks 241. The upper surface of the end rail plate 233 is provided with a guide rail corresponding to the docking rail groove 201, so that after the rotating ring 212 rotates to the position where the guide rail frame 23 faces the front of the vehicle, the autonomous moving block 241 set in the docking rail groove 201 can move to the guide rail of the end rail plate 233 and move horizontally on the guide rail of the end rail plate 233. A battery and a communication controller are installed in the autonomous moving block 241, so that it can work independently according to the signal command after receiving a wireless control signal without external power supply. A charging port that can be connected to the battery charging head of the autonomous moving block 241 is provided in the docking rail groove 201 to charge the autonomous moving block 241 in a timely manner.

[0031] The autonomous moving block 241 is provided with moving wheels that can move within the docking rail groove 201 but cannot disengage from it, so that the autonomous moving block 241 can move freely within the docking rail groove 201 and continue to move on the guide rail of the end rail plate 233 after moving to the end rail plate 233.

[0032] The rear end support rod 243 is mounted on the autonomous moving block 241 located at the front, and the central support rod 242 is mounted on the autonomous moving block 241 located at the rear. A pair of fire extinguishing components 2 are parallel to each other on the roof of the 500-ton cab of the off-road vehicle. The central support rod 242 and the rear end support rod 243 of the two fire extinguishing components 2 are arranged facing each other to place a fire blanket 4 between the two fire extinguishing components 2. A counterweight head 41 is installed at each of the four corners of the fire blanket 4. A hexagonal groove 401 is installed at the center of each counterweight head 41. Hexagonal telescopic shafts are installed at the ends of the central support rod 242 and the rear end support rod 243. The counterweight heads 41 at the four corners of the fire blanket 4 are connected to the hexagonal... The telescopic shaft is installed in conjunction with two pairs of central support rods 242 and tail support rods 243 that can be separated and laid flat on the guide rails of the end rail plate 233. The hexagonal telescopic shaft can be retracted into the ends of the central support rods 242 and tail support rods 243, so that the counterweight head 41 is separated from the central support rods 242 and tail support rods 243, and thus falls from the end rail plate 233 under the action of the gravity of the counterweight head 41. Preferably, the end of the central support rod 242 is provided with a motor that can drive the hexagonal telescopic shaft to rotate axially, so that after the new fire blanket 4 is installed in a flat state, the hexagonal telescopic shaft can roll up the fire blanket 4 by rotation and store it on the roof of the cab of the off-road vehicle 500.

[0033] After the fire is extinguished by spraying fire extinguishing agent onto the burning vehicle, the retraction assembly 24, which carries the fire blanket 4, moves to the end rail 233. Then, the guide rail 23 extends to cover the entire roof of the burning vehicle, while the autonomous moving block 241 moves in opposite directions to unfold the fire blanket 4 over the burning vehicle. After the unfolded fire blanket 4 detaches from the guide rail 23, it falls to cover the body of the burning vehicle to isolate it from the air and prevent reignition. Preferably, the off-road vehicle body 500 is also equipped with a vehicle-moving fire extinguishing robot. The connecting hose of the vehicle-moving robot sprays perfluoroacetone fire extinguishing agent onto the battery pack at the bottom of the burning vehicle for rapid cooling and extinguishing of the battery fire. The off-road vehicle body 500 is also equipped with a rescue lighting line and a robot dog for on-site lighting rescue and fire scene reconnaissance.
