[0015] (III) Beneficial Effects
[0016] This utility model provides a throwing device for rescue drones, which has the following beneficial effects:
[0017] 1. The throwing device of this rescue drone, through the setting of sliding block, sliding shaft, rectangular plate and drive motor, allows the equipment to place the materials to be thrown into the throwing placement box before throwing. Then, the throwing placement box is pushed inward, and the sliding buckle is locked onto the surface of the controllable pushing block. Then, the drive motor is started to drive the transmission rod to rotate, so that the angle of the rotating plate can be adjusted. This allows the equipment to adjust the angle according to the actual needs, thus effectively avoiding the possibility that the angle and height of the equipment before throwing may be inaccurate, resulting in deviation of the throwing location.
[0018] 2. The throwing device of this rescue drone, through the setting of a throwing placement box, a sliding buckle, and a controllable push block, first places the materials to be thrown inside the throwing placement box, then pushes the throwing placement box inward, and the sliding buckle is locked onto the surface of the controllable push block to fix the items. When the device moves to a suitable position, a push command is given to the controllable push block, causing the controllable push block to push back the sliding buckle. The push back of the sliding buckle allows the throwing placement box to move freely, thereby enabling the device to throw the items more effectively. This effectively avoids the situation where, when the device reaches the throwing location, the items are not easily thrown out and get stuck inside the device. Attached Figure Description

Through the arrangement of the sliding block 4, the sliding round shaft 8, the rectangular plate 7, and the drive motor 12, before the device throws materials, the materials to be thrown are first placed inside the throwing placement box 15, then the throwing placement box 15 is pushed inward, the sliding buckle 16 is locked onto the surface of the controllable pushing block 17, and then the drive motor 12 is started to drive the transmission rod to rotate, causing the rotating plate 9 to adjust its angle. Thus, the device can adjust the angle according to the actual needs, thereby achieving... This effectively avoids the possibility of inaccurate angle and height before the device throws, which could lead to deviations in the throwing location. A rotating plate 9 is fixedly connected to the surface of the sliding shaft 8, and a pushing plate 10 is fixedly connected inside the rotating plate 9. With the setting of the throwing placement box 15, the sliding buckle 16, and the controllable pushing block 17, the material to be thrown is first placed inside the throwing placement box 15, and then the throwing placement box 15 is pushed inward. The sliding buckle 16 is locked onto the surface of the controllable pushing block 17 to fix the item. When the device moves to the appropriate position, a pushing command is given to the controllable pushing block 17, causing the controllable pushing block 17 to push back the sliding buckle 16. The push back of the sliding buckle 16 allows the throwing placement box 15 to move freely, thereby enabling the device to throw the item more effectively. This effectively avoids the possibility that the item may not be thrown out easily and may get stuck inside the device when it reaches the throwing location.
