It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0018] Example: Reference Figures 1 to 4 This application specifically includes the structures of two embodiments: First embodiment: Reference Figure 1 and Figure 2 The device for airdropping and receiving satellites by drone in this embodiment includes a cross rope frame structure, a drone device 1, a rope 2 and a hook 3, and a frame assembly for placing a satellite station is connected below the cross rope frame structure. The two ends of the rope 2 are respectively connected to the drone device 1 and the hook 3; The frame assembly includes a frame base 4 and connecting rods 5. The connecting rods 5 are located at both ends of the frame base 4, which is used to place the satellite station. The cross rope frame structure includes a fixing component, a rope frame component, and a connecting rope 6. The fixing component includes a first fixing rod 7 and a first connecting seat 8. The first connecting seat 8 is located on the side of the first fixing rod 7. The first fixing rod 7 and the first connecting seat 8 are provided with hinged connection parts. The two ends of the first fixing rod 7 are respectively connected to the connecting rod 5 to realize the connection between the cross rope frame structure and the frame component. There are two rope frame assemblies. Each rope frame assembly includes a reset member 9 and a rope frame rod 10. There are two rope frame rods 10, which are arranged opposite to each other. One end of the rope frame rod 10 is hinged to the hinged connection part. The other ends of the two rope frame rods 10 in the same rope frame assembly are connected to each other. The connecting ropes 6 at the two rope frame assemblies are arranged in a cross pattern. The specific structure of the rope frame assembly located within the fixed assembly is as follows: The rope frame rod 10 of one rope frame assembly is hinged to the first fixed rod 7 through a hinged connection part, and the rope frame rod 10 of another rope frame assembly is hinged to the first connecting seat 8 through a hinged connection part. A reset member 9 is provided between the rope frame rod 10 and the first fixed rod 7, and a reset member 9 is provided between the two rope frame rods 10 of the first connecting seat 8. As the other ends of the two rope frame rods 10 of the rope frame assembly approach each other, the reset member 9 is in a stretched state. When the reset member 9 is in a natural state, the other ends of the two rope frame rods 10 of the rope frame assembly are in a state of being far apart, and the connecting rope 6 is in an open state. According to the above structure, the UAV device 1 hovers close to the cross rope frame structure, and the hook 3 is close to the cross rope frame structure. The connecting ropes 6 on the cross rope frame structure are arranged in a crisscross pattern, increasing the contact area between the connecting ropes 6 and the hook 3, thereby increasing the capture probability. During retrieval, the hook 3 grabs any position on the connecting rope 6, the UAV device 1 takes off and lifts the hook 3, and under the action of tension, it pulls the tension rope to drive the two rope frame rods 10 of the rope frame assembly to close together, that is, the other ends of the two rope frame rods 10 approach each other to form a bundle structure. At this time, the hook point of the hook 3 and the cross rope frame structure automatically center. Finally, the UAV device 1 hovers, the hook 3 lifts the satellite station into the air, and the UAV device 1 flies away.

[0019] Second embodiment: Reference Figure 3 and Figure 4 The difference between this embodiment and the first embodiment is that a cover assembly 11 for placing a satellite station is connected below the cross rope frame structure. At the same time, according to the structural characteristics of the cover assembly 11, the fixing assembly includes a first fixing seat 12 and a second connecting seat 13. The second connecting seats 13 are evenly distributed on the side of the first fixing seat 12 with the central axis of the first fixing seat 12 as the center. The rope frame rod 10 is hinged to the second connecting seat 13, and a reset member 9 is provided between the rope frame rod 10 and the second connecting seat 13.

[0020] The reset components in the two embodiments described above can specifically be reset structures that utilize the elastic potential energy of a spring, or they can be reset by a motor drive.

[0021] In summary, the structural design of this application is reasonable. The connecting ropes of the cross-rope frame structure are arranged in a crisscross pattern, which increases the contact area with the hook and facilitates the capture of satellite stations. During the recovery operation, after the hook grabs the connecting rope, the UAV takes off and pulls, and the pulling force causes multiple rope frame rods to close together to form a bundle structure. The hook and the attachment point of the cross-rope frame structure automatically center, eliminating the need for precise aiming at a single target point. This allows the UAV to capture and recover satellites even when there is a large range of error between the UAV and the target point. This application is mainly used in emergency communication and disaster relief scenarios. The technical problem it solves is to reduce the aiming accuracy requirements of UAVs in capturing satellite equipment and allow for capture and recovery even when there is a large range of error between the distance between the UAV and the target.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way.
