Description

Technical Field

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

[0002] With the increasing popularity of new energy vehicles, more and more people are using electric vehicles in their daily lives, which brings with it the issue of fire safety for electric vehicles. Electric vehicle batteries are prone to catching fire under conditions of high external temperatures or impacts. Battery fires are complex, spread rapidly, and are difficult to extinguish. Timely cooling of the battery is necessary to control the fire during extinguishing.

[0003] Since the battery packs of electric vehicles are mostly located under the vehicle body, and the traditional fire extinguishing method uses fire-fighting water to spray a large amount of water onto the entire vehicle, this method cannot accurately cool the batteries under the vehicle body, resulting in an unsatisfactory fire extinguishing effect. If a large vehicle or a vehicle with a low chassis catches fire, the fire extinguishing effect of the traditional fire extinguishing method will be further weakened, and it will not be able to effectively control the fire.

[0004] Most existing fire extinguishing devices for new energy vehicles are only designed for fixed fire suppression at the bottom of the vehicle. However, due to the different impact conditions of new energy vehicles, the ignition range of the fire point also varies. Existing fixed frames are sometimes unable to cover a large area of ​​fire, while large frames cannot enter the bottom of small new energy vehicles. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-7 A fire extinguishing device for new energy vehicles comprises a fire extinguishing frame 1 and a main rod 2. The fire extinguishing frame 1 consists of a main frame 3 and two secondary frames 4, which are slidably connected. The main rod 2 is rotatably mounted on the main frame 3. A pushing mechanism is provided between the main frame 3 and the main rod 2. Multiple nozzles 5 are installed on both the main frame 3 and the two secondary frames 4. When this device extinguishes fires in new energy vehicles, the ignition range of the fire point varies depending on the impact of the vehicle. This device achieves variability in the fire extinguishing range by telescopically cooperating between the main frame 3 and the two secondary frames 4. The pushing mechanism on the main rod 2 controls the deployment range of the two secondary frames 4, thereby regulating the fire extinguishing range.

[0027] As a preferred embodiment, the pushing mechanism includes a connecting sleeve 6, which is slidably disposed on the main rod 2. A threaded sleeve 7 is provided on the top of the connecting sleeve 6, and the threaded sleeve 7 is threadedly connected to the main rod 2. Extension tubes 8 are provided at both ends of the main frame 3, and the extension tubes 8 are slidably engaged with the two sub-frames 4. A connecting rod 9 is rotatably disposed on the two sub-frames 4, and the end of the connecting rod 9 away from the sub-frames 4 is rotatably connected to both sides of the connecting sleeve 6. A connecting component is provided between the connecting sleeve 6 and the threaded sleeve 7. During the use of this device, the connecting sleeve 6 is pushed to move on the main rod 2 by the pushing mechanism, which in turn pushes the extension of the two sub-frames 4 through the connecting rod 9. The threaded sleeve 7 is rotated, causing the threaded sleeve 7 to displace on the main rod 2, thereby driving the movement of the connecting sleeve 6.

[0028] As a preferred technical solution of this embodiment, the connecting component includes a rotating member 10, which is rotatably mounted on the bottom of the threaded sleeve 7. A locking sleeve 11 is rotatably mounted on the outside of the rotating member 10. A locking block 12 is provided at the bottom of the inner wall of the locking sleeve 11. A slot 13 is provided at the top of the connecting sleeve 6. Through grooves 14 are provided on both sides of the top of the connecting sleeve 6. The locking block 12 is adapted to the slot 13, and the through groove 14 matches the shape of the locking block 12. When this device is in use, in order to deal with emergencies, the connecting component can be used to contact the connection between the connecting sleeve 6 and the threaded sleeve 7. The connecting sleeve 6 can be moved directly by sliding, driving the two sub-frames 4 to unfold, so that the fire extinguishing frame 1 can be quickly unfolded to the maximum range. By rotating the locking sleeve 11, the locking block 12 of the locking sleeve 11 is disengaged from the slot 13 at the top of the connecting sleeve 6, so that the locking block 12 is in the position of the through groove 14. Pulling down the connecting sleeve 6 will disengage the connecting sleeve 6 from the locking sleeve 11.

[0029] As a preferred embodiment, the top of the locking sleeve 11 has four grooves 15 arranged in a cross shape. Four locking posts 16 are slidably installed on the side wall of the rotating member 10. The four locking posts 16 are adapted to the grooves 15. A spring 17 is fixedly installed between the locking posts 16 and the rotating member 10. The locking sleeve 11 can be rotated 90° to make the locking block 12 fit into the through groove 14. In order to ensure the accuracy of the rotation angle, the locking posts 16 arranged in a cross shape are used for judgment. After the locking sleeve 11 is rotated 90°, the locking posts 16 will engage with the grooves 15 again. The support of the locking posts 16 by the spring 17 makes the user feel a clear sense of jerk, so as to judge whether the locking block 12 is in the through groove 14.

[0030] As a preferred technical solution of this embodiment, a connector 18 is fixedly installed on the sub-frame 4, and a connecting piece 19 is rotatably installed on the connector 18. The connecting piece 19 and one end of the connecting rod 9 are rotatably connected. The rotation axis of the connecting piece 19 and the connector 18 is coaxial with the connection axis of the main rod 2 and the main frame 3 to adapt to the rotation of the main rod 2.

[0031] As a preferred technical solution in this embodiment, casters 20 are fixedly installed on the four corners of the two sub-frames 4; the casters 20 facilitate the movement of the entire fire extinguishing frame 1.
