Description

Technical Field

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

[0002] Forest fires typically occur in mountainous areas with complex terrain and difficult access, making firefighting extremely challenging. Currently, long-range deployment of forest fire extinguishing bombs has become an effective firefighting method. By launching these bombs from a distance, firefighters can avoid close contact with the fire, reducing casualties. Furthermore, the bombs are easy to carry and deploy quickly, enabling a rapid response to suppress the fire in its initial stages and control its spread, buying time for further action. Consequently, fire extinguishing bomb launching devices, due to their efficient and rapid initial fire suppression capabilities, have gradually become an important research direction in the field of firefighting equipment. However, existing fire extinguishing bomb launching devices generally suffer from the following drawbacks, severely limiting their applicability and widespread application:

[0003] 1. Existing projectile devices have unreasonable structural designs and poor portability: Traditional fire extinguishing projectile projectile devices mostly adopt fixed frames or rigid integrated structures, which are bulky and cannot be folded. For example, the main support of some devices is welded from metal pipes, and the launch rail is fixed to the base with bolts, resulting in a large overall space occupation of the device. During transportation and storage, special vehicles or large warehouse space are required, which increases transportation or storage costs.

[0004] 2. Lack of projectile angle adjustment function and insufficient adaptability: Traditional fire extinguishing bomb projectile devices use a fixed frame or integrated structure, which means that the projectile angle is preset to a single angle (such as 30° or 45°) at the factory. It cannot be dynamically adjusted according to the fire situation, making it difficult for the fire extinguishing bomb projectile device to cope with the differentiated needs of fire sources at different distances, resulting in uneven coverage of fire extinguishing agent or waste of resources.

[0031] A fire extinguishing grenade launching device includes a bottom support 1 and a grenade support plate 2 for holding fire extinguishing grenades; a grenade holder 3 disposed on the grenade support plate 2 to support the bottom of the fire extinguishing grenade, wherein the grenade holder 3 is rotatably connected to one side of the bottom support 1 to drive the grenade support plate 2 to rotate and adjust the launching direction of the fire extinguishing grenade; and a support assembly 4 hinged to the other side of the bottom support 1, the free end of the support assembly 4 being movably connected to the side of the grenade support plate 2 away from the grenade holder 3, the support assembly 4 for supporting the grenade support plate 2 and for adapting and adjusting the launching angle of the fire extinguishing grenade.

[0032] With the above configuration, the ammunition holder 3 and the ammunition support plate 2 are rotatably mounted on the bottom support 1 and supported by the support assembly 4. The three form a triangular structure, allowing the ammunition holder 3 and the ammunition support plate 2 to be adjusted accordingly. Since the fire extinguishing ammunition is placed on the ammunition support plate 2, the launch angle of the fire extinguishing ammunition can also be adjusted. This allows the fire extinguishing ammunition launching device to meet the different needs of fire sources at different distances, avoiding uneven coverage of extinguishing agent or waste of resources. During transportation and storage, the ammunition holder 3 and the ammunition support plate 2 can be rotated and folded onto the bottom support 1 first, and then the support assembly 4 can be rotated and folded onto the ammunition support plate 2, thereby reducing the space occupied by the fire extinguishing ammunition launching device and saving transportation or storage costs.

[0033] Specifically, in this embodiment, the support assembly 4 includes a rotating rod 401 and a telescopic rod 402. One end of the rotating rod 401 is hinged to the bottom support 1, and the other end of the rotating rod 401 is slidably connected to the telescopic rod 402. Specifically, the telescopic rod 402 has a plurality of positioning holes 403 evenly distributed along its axial direction. The rotating rod 401 has a mounting hole and also includes a positioning pin 404. The telescopic rod 402 is controlled to pass into the rotating rod 401, and at the same time, one of the positioning holes 403 is aligned with the mounting hole. At this time, the positioning pin 404 passes through the mounting hole and the positioning hole 403, so that the length of the support assembly 4 can be controlled and adjusted so that the support assembly 4 matches the rotation angle of the spring tray 3 and the spring support plate 2.

[0034] Meanwhile, a limiting frame 5 is hinged to the telescopic rod 402. The limiting frame 5 is used to support the free end of the flare-following plate 2. At the same time, the limiting frame 5 is used to cooperate with the flare-following plate 2 to restrain the fire extinguishing projectile. Specifically, the limiting frame 5 includes a lower half limiting ring 501 connected to the telescopic rod 402 and an upper half limiting ring 502 hinged to one end of the lower half limiting ring. The limiting frame 5 fixes the position of the fire extinguishing projectile and prevents it from moving during launch.

[0035] The lower half of the limiting ring 501 is provided with a latch 503 at the other end, and the upper half of the limiting ring 502 is provided with a hook 504 for engaging with the latch 503 at its free end. The latch 503 and the hook 504 achieve closure to restrain the upper end of the fire extinguishing bomb. The structure is simple and easy to operate.

[0036] The fire extinguishing plate 2 is a component with a circular arc cross-section, which fits the shape of the fire extinguishing bomb to increase stability and prevent the fire extinguishing bomb from detaching.

[0037] The extinguishing bomb holder 3 has a support groove 301 through which the lower end of the extinguishing bomb can be inserted. The side wall of the extinguishing bomb holder 3 is provided with a locking mechanism for locking the bottom of the extinguishing bomb. Specifically, the locking mechanism includes a stop pin 302. One end of the stop pin 302 extends out of the support groove 301 and is connected to a pull ring. A compression spring 303 is sleeved on the stop pin 302. The compression spring 303 acts on the stop pin 302 so that the axis of the stop pin 302 has an initial state of being inserted into the support groove 301. When placing the extinguishing bomb, first pull the pull ring to move the stop pin 302 outward. At this time, the lower end of the extinguishing bomb is inserted into the support groove 301. Then, the pull ring is released. At this time, the stop pin 302 moves into the support groove 301 under the action of the compression spring 303 and abuts against the side wall of the lower end of the extinguishing bomb, thereby achieving axial fixation of the extinguishing bomb.

[0038] In addition, the ammunition holder 3 has at least one mounting hole, which is connected to the bearing groove 301. In this embodiment, there are two mounting holes, one of which is used to install an ignition contact 305, and the other is used to install a grounding contact 304.
