[0002] For the ignition points in dangerous places such as high-rise buildings, forests, chemical plants, etc., using aircraft such as UAVs to drop bombs for fire fighting has the advantages of fast response speed, high accuracy, safety of firefighters, and the ability to handle long-distance fires. For fire-fighting UAVs, it is necessary to carry fire extinguishing agents such as dry powder and drop them into the fire scene. To be suitable for the dropping of UAVs, these fire extinguishing agents are often packaged into special fire bombs.

[0003] At present, most of the fire bombs on the market are of three types: launch-type fire bombs, direct-drop fire bombs, and gliding fire bombs. Due to the different projection methods of the three fire bombs, they are respectively applied to different fire-fighting scenarios. In the prior art, the three fire bombs cannot be mutually universal. When the inventory of one type of fire bomb is insufficient, it is necessary to separately purchase the out-of-stock fire bomb, and the practicability is poor. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0025] Refer to Figures 1 - 5 As shown, the present utility model provides a fire bomb with a glider wing kit, including a fire extinguishing warhead 1, a warhead upper cover 2 and a tail control rudder 5. A docking part 16 is provided at the tail of the fire extinguishing warhead 1. A docking groove 15 adapted to be inserted into the docking part 16 is provided at the front end of the tail control rudder 5. And a bolt connecting member 3 for fixing the tail control rudder 5 is provided at the docking part 16. Four uniformly distributed rudder panels 6 are provided at the tail of the tail control rudder 5. U-shaped fixing rings 9 are provided on both sides of the bottom of the warhead upper cover 2. And the two U-shaped fixing rings 9 and the warhead upper cover 2 cooperate to surround the outside of the fire extinguishing warhead 1. Through holes 14 for sleeving the U-shaped fixing rings 9 are provided through both sides of the bottom of the warhead upper cover 2. Adjusting components 4 for driving the two ends above the U-shaped fixing rings 9 to approach or move away from each other are provided on both sides inside the warhead upper cover 2. Two rotating seats 7 are fixedly connected to the upper side of the warhead upper cover 2. Glider wing plates 8 are horizontally rotatably connected to the upper ends of the two rotating seats 7. And elastic torsion members for driving the glider wing plates 8 to rotate to the side perpendicular to the axis direction of the warhead upper cover 2 are provided on both of the two rotating seats 7. It is worth mentioning that the tail control rudder 5 receives the target coordinates transmitted by the drone and the pre-input target coordinates through a data link to control the gliding bomb to fly towards the target. A Beidou satellite positioning and GPS hybrid positioning system is installed inside the tail rudder. A direction control servo motor mechanism is installed on the tail wing to adjust the direction. The control method of the tail control rudder 5 is a prior art and can be realized by simple programming by those skilled in the art. The present application mainly protects the connection mode of the components, and the specific control method of the tail control rudder 5 will not be elaborated here.

[0026] Refer to Figure 2 As shown, the bolt connecting member 3 includes fixing holes 3a provided on both sides of the end of the tail control rudder 5. And the two fixing holes 3a are distributed at 180 degrees and are both communicated with the docking groove 15. Bolts 3b are inserted into both of the two fixing holes 3a. Threaded holes 3c for threaded connection with the bolts 3b are provided on the side wall of the docking part 16. After the docking part 16 is inserted into the docking groove 15, the bolts 3b are inserted into the fixing holes 3a and the threaded holes 3c at the same time and rotated, and the connection between the fire extinguishing warhead 1 and the tail control rudder 5 can be completed.

[0027] Specifically, the U-shaped fixing ring 9 is made of elastic metal. A rubber pad (not shown in the figure) that abuts and fits with the outer wall of the fire extinguishing warhead 1 is provided on the bottom surface of the warhead cover 2. When the opening ends of the U-shaped fixing ring 9 made of elastic metal are relaxed, it can loosen through its own elasticity. At the same time, the rubber pad can improve the fit between the warhead cover 2 and the fire extinguishing warhead 1, making the installation more firm.

[0028] Refer to Figure 4 As shown, the adjusting assembly 4 includes a bidirectional screw 4a rotatably connected inside the warhead cover 2. Threaded sleeves 4b are threadedly connected to both sides of the bidirectional screw 4a. The bottom surfaces of the two threaded sleeves 4b are respectively connected to the opening ends of the U-shaped fixing ring 9 through connecting bands 4c. The bidirectional screw 4a can be rotated by a hex wrench. At this time, the two threaded sleeves 4b threadedly connected to it approach each other. The opening ends of the U-shaped fixing ring 9 are pulled closer through the connecting bands 4c to complete the contraction of the U-shaped fixing ring 9, so that the warhead cover 2 is fixed on the fire extinguishing warhead 1 through the tightening fit of the U-shaped fixing ring 9. When the two threaded sleeves 4b move away from each other, the U-shaped fixing ring 9 is also relaxed, and at this time, the warhead cover 2 can be removed from the fire extinguishing warhead 1.

[0029] Specifically, the connecting band 4c is made of plastic. When the two threaded sleeves 4b move away from each other, the U-shaped fixing ring 9 can be pushed to open and relax through the characteristics of the plastic material.

[0030] Refer to Figure 3 As shown in FIG. 4 or 5, the elastic torsion member includes a component groove 10 opened at the upper end of the rotating seat 7. A spiral spring 11 is wound in the component groove 10, and both ends of the spiral spring 11 are respectively connected to the inner wall of the component groove 10 and the gliding wing plate 8. And a limiting component for fixing the rotation angle of the gliding wing plate 8 is provided on the rotating seat 7. The limiting component includes a convex rod 13 fixedly connected to the bottom surface of the gliding wing plate 8. A C-shaped clamping ring 12 that is clamped and adapted to the convex rod 13 is fixedly connected to the upper end of the side wall of the rotating seat 7. When used as a gliding fire extinguishing bomb, the two gliding wing plates 8 are in a contracted state. At this time, the orientations of the two gliding wing plates 8 are consistent with the axis direction of the fire extinguishing warhead 1. At the same time, the spiral spring 11 is in an elastically deformed state. When the fire extinguishing warhead 1 is ejected from the unmanned aerial vehicle, under the elastic force of the spiral spring 11, the two gliding wing plates 8 are respectively rotated horizontally by 90 degrees to unfold, and at the same time, the convex rod 13 is rotated and clamped into the C-shaped clamping ring 12 to complete the fixation after the gliding wing plates 8 are extended.

[0031] With the above structure, by placing the tail control rudder 5 at the tail of the fire extinguishing warhead 1, the docking part 16 and the docking groove 15 of the two are assembled and connected and fixed by the bolt connecting piece 3. Then, the warhead upper cover 2 and the U-shaped fixing ring 9 are sleeved around the fire extinguishing warhead 1. Subsequently, the adjusting assembly 4 drives the open ends of the U-shaped fixing ring 9 to approach each other. At this time, the U-shaped fixing ring 9 gradually tightens under the fire extinguishing warhead 1 to complete the fixation of the warhead upper cover 2. The two gliding wing plates 8 above the warhead upper cover 2 are extended by the elastic torsion members. At this time, the fire extinguishing warhead 1 can be used as a gliding fire extinguishing bomb. On the contrary, after disassembling the assembled components, the fire extinguishing warhead 1 can be used as an ordinary fire extinguishing bomb, and at the same time, the effect of upgrading and transforming the old inventory fire extinguishing bombs can be achieved.

[0032] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
