DETAILED DESCRIPTION
[0014] The embodiment first provides an unmanned aerial vehicle fire attack device, as shown in Figures 1-4 The unmanned aerial vehicle 1 (four wings, and with a detachable power module), a gimbal 2 is installed at the front end of the unmanned aerial vehicle 1, and a photoelectric reconnaissance load 3 is installed below the gimbal 2, which is used to obtain the picture in the forward direction of the unmanned aerial vehicle 1. At the same time, an obstacle avoidance radar 4 for detecting obstacles in the forward direction of the unmanned aerial vehicle 1 is also installed at the front end of the unmanned aerial vehicle 1. The obstacle avoidance radar 4 and the photoelectric reconnaissance load 3 are located above and below respectively to prevent interference, and both of them are mature components in the art, and their structures will not be described here. The person skilled in the art can purchase them from the market as needed.
[0015] An ammunition mounting and releasing mechanism is installed at the bottom of the unmanned aerial vehicle 1. The mechanism includes a pod 5, the tail of the pod 5 forms a downward extending wing, the head of the pod 5 forms a downward opening notch, and a downward opening concave plate 6 is installed outside the head of the pod 5. A plug-in joint 7 is vertically installed on the concave plate 6, one end of the joint 7 is connected with the power module of the unmanned aerial vehicle 1.
[0016] The pod 5 has a mounting plate 8 installed inside its cabin, and a servo motor 9 is mounted on the mounting plate 8 (the servo motor 9 is located near the middle section of the total length of the pod 5 and the concave plate 6). In practical applications, the electro-optical reconnaissance payload 3, the obstacle avoidance radar 4, and the servo motor 9 are all connected to the controller of the UAV 1 and the power module of the UAV 1. The controller of the UAV 1 interacts with an external handheld control terminal via wireless communication (this method is existing technology and will not be described in detail here). The handheld control terminal directly controls the flight status and trajectory of the UAV 1, displays key information of the UAV 1 in real time, such as battery level, altitude, and speed, and receives real-time reconnaissance images transmitted by the electro-optical reconnaissance payload 3 and obstacle information sensed by the obstacle avoidance radar 4.
[0017] The actuator of the servo motor 9 is equipped with a follower sleeve 10 that passes through one side wall of the pod 5 and is rotatably connected to the side wall. The end of the follower sleeve 10 forms a boss 11 with a gradually decreasing diameter from the inside to the outside, and a latch 12 is provided at the end of the boss 11 with one end extending radially outward along the follower sleeve 10. The two ends of the mounting plate 8 are provided with two downward-facing protective wings 14. In actual application, a top plate 15 connected to the mounting plate 8 is also provided below the two protective wings 14 (extending upward on both sides and fixed to the mounting plate 8). The ammunition is hung in the pod 5 along the length direction of the pod 5 through straps 13 (the straps 13 are required to have sufficient width and mechanical properties to support the ammunition). The side plates of the protective wings 14 abut against the side wall of the ammunition, the top plate 15 abuts against the top surface of the ammunition, and the tail of the ammunition abuts against the protective plate. The head of the ammunition passes through the slot of the head of the pod 5 and is inserted into the slot of the concave plate 6. The connector 7 located in the concave plate is inserted into the fuse interface of the ammunition to supply power to the fuse.
[0018] One end of the strap 13 is fixed to one side of the mounting plate 8, and the other side is provided with a retaining ring 16. When loading ammunition, the retaining ring 16 is hung on the boss 11 (the retaining state can be ensured by holding the retaining ring 16 by hand). Then, the external handheld operating terminal controls the servo motor 9 to rotate at a fixed angle to drive the follower sleeve 10 and the locking buckle 12 at the end to rotate so that the locking buckle 12 rotates to face upward (in the initial state, the locking buckle 12 faces vertically downward, and when loading, the locking buckle 12 passes through the retaining ring 16). At this time, due to the restriction of the locking buckle 12, the retaining ring 16 cannot slip off the boss 11, thereby realizing the loading of ammunition. When the ammunition needs to be released, the servo motor 9 is controlled by an external handheld operating terminal to rotate at a fixed angle, which drives the follower sleeve 10 and the locking buckle 12 at the end to rotate, so that the locking buckle 12 rotates to face downward. At this time, the locking buckle 12 no longer restricts the retaining ring 16. Under the weight of the ammunition and the action of the boss 11, the retaining ring 16 will slide off the boss 11. At the same time, the connector 7 will directly disengage from the ammunition fuse interface (due to the gravity of the ammunition), thereby realizing the release of the ammunition.
[0019] The embodiment also provides a fire attack method based on the unmanned plane. S1, after receiving the instruction, going to the combat site, then assembling the photoelectric detection load and the obstacle avoidance radar to the unmanned plane, and mounting the ammunition to the unmanned plane to form the unmanned plane fire attack device; S2, starting the unmanned plane for self-checking, and performing path planning according to the task target position information; S3, after the self-checking is completed, the operator controls the unmanned plane to fly towards the target point through the handheld operation terminal, and detects the ground along the way according to the real-time picture returned by the photoelectric detection load; S4, when reaching the target area, the unmanned plane flies at a low speed and searches and confirms the target; S5, after confirming the target, the unmanned plane is adjusted to be directly above the target, and the ammunition is released (i.e., the ammunition is released); then the unmanned plane climbs and observes the damage effect, and decides whether to attack again according to the damage effect; if the second attack is needed, the unmanned plane returns to load the ammunition and continues the fire attack; otherwise, after returning, the operator recovers the unmanned plane and returns to the assembly place.
[0020] The fire attack method reduces the physical consumption of soldiers during long-distance raids or continuous combat, and ensures that the soldiers always maintain high combat effectiveness. Whether it is jungle navigation, urban street fighting or mountain raiding, the soldiers can respond to changes in the battlefield more quickly and take the initiative in complex environments. After completing the ammunition release task, the unmanned plane can be accurately recovered and reloaded with ammunition, so that it can be used in different combat scenes for many times, greatly reducing the use cost and being suitable for long-term and continuous combat deployment requirements.
[0021] The above only describes the preferred embodiments of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be regarded as the protection scope of the present application.
