Description

Technical Field

[0001] This invention relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to an aerial network opening device and method for UAVs. Background Technology

[0002] Drones are characterized by their low cost, which has led to their widespread use but also made their management difficult. This has spurred the development of various counter-drone solutions to deal with unauthorized drone flights, including electromagnetic interference, kinetic energy impact, and netting for capture. While net-based capture methods offer a high success rate against various types of drones due to their large capture area, anti-drone drones carrying large-area net structures are subject to significant interference during takeoff, target locking, and pursuit maneuvers. This interference reduces the performance of the anti-drone drone and limits its capture success rate.

[0003] Based on existing net-trapping anti-drone technology, there are still a series of technical challenges, such as the bulky net-trapping structure, large structural size, and inability to quickly replace the net-trapping structure. Summary of the Invention

The inner rope ring 8 is provided at the root of the sixth section of carbon tube 38, and an outer spring sleeve is provided at the tip of the sixth section of carbon tube 10. The spring 4 is provided outside the telescopic carbon tube 10. The net opening mechanism consists of a net opening actuator 15, an inner hook 16, a hook disc 17, and a net opening angle control plate 18. The net opening mechanism 2 is located inside the main body mechanism 1. The hook rope 32 passes through the inner rope ring 8 and is finally locked on the upper part of the inner hook 16 of the net opening mechanism 2. The aforementioned net box body 12 and net box cover 13 are connected by a snap-fit, and the net box cover 13 is equipped with a capture net inside. The reinforcing rib 14 is integrally set with the main structure 6. The net box body 12 is connected to the main structure 6 by screws. The bottom of the outer spring sleeve 9 is provided with a protrusion 19, and the protrusion 19 is provided with a through hole.

The net opening actuator 15 is located below the hook plate 17, and the net opening actuator 15 and the hook plate 17 are connected by a net opening angle control plate 18. The inner hook 16 is installed on the hook plate 17, and the hook plate 17 is installed on the symmetrical plane above and below the telescopic structure 3. When the net opening actuator drives the net opening angle control plate 18, the inner hook 16 releases the hook rope 32 and simultaneously releases the net pulling rope 7. Under the action of the spring 4, the capture net is pulled out from the net box cover 13 and the net is opened.

[0020] The main structure 6 of this invention includes a body mounting interface 20, a reinforcing rib 14, a telescopic mechanism mounting interface, a net-opening mechanism mounting interface 11, a net-opening actuator mounting interface 21, and a net box mounting interface 22.

The net-opening mechanism mounting interface 11 is located on the second transverse positioning plate 24 and is used to install the hook plate 17. The area of ​​the second transverse positioning plate 24 is smaller than the area of ​​the first transverse positioning plate 23. A partition 25 is provided between the main structure 6 and the net box body 12, and the net box mounting interface 22 is located on the partition 25.

[0021] like Figure 5 As shown, the opening angle control plate 18 is located above the opening actuator 15. The opening angle control plate 18 consists of four opening hooks 16 arranged on the circumference. The hook plate 17 has a double-layer structure with a cavity between the upper and lower layers. Four locking slots 26 are evenly spaced on the outer circumference of the hook plate 17, and the locking slots 26 cooperate with the inner hooks 16. The locking slots 26 and the inner hooks 16 cooperate with each other to ensure the rotation and relaxation of the inner hooks 16. At the same time, the thickness and width of the upper and lower layers are matched with the locking slots 26. When the thickness of the hook plate 17 is large, the locking slots 26 are set relatively large. At the same time, it is necessary to ensure the efficient installation of the locking slots 26 and ensure that they can rotate.

[0022] The top of the aforementioned inner hook 16 is inclined, and a limiting groove is provided at the bottom of the inclined part. The limiting groove is not marked in the figure. The hook rope 32 is hooked and fixed on the limiting groove for limiting. Both side walls of the locking groove 26 are provided with threaded through holes. The middle part of the inner hook 16 is provided with a positioning rotating hole that matches the threaded through hole. The middle part of the inner hook 16 is rotated and fixed under the action of the bolt. During installation, the pulling rope 7 should be fixed on the capture net first. Then, the inner hook 16 should be in a vertical state. Ensure that the pulling rope 7 is tensioned and fixed on the inner hook 16. The locking groove 26 on the inner hook 16 is the same size as the locking groove 26 on the hook plate, which ensures the tensioning, pulling out and releasing of the capture net.

[0023] In this embodiment, the fuselage mounting interface 20, the net-opening actuator mounting interface 21, and the net box mounting interface 22 respectively fix the net-opening mechanism, the net-opening actuator 15, and the net box cover 13 with bolts. The net box cover 13 has four pieces and is located on the side of the net box body 12. At the same time, the fuselage mounting interface 20, the net-opening actuator mounting interface 21, and the net box mounting interface 22 facilitate the installation of components with the help of bolts.

[0024] The aforementioned net-opening actuator 15 is a servo motor, and the output shaft of the net-opening actuator 15 is fixedly connected to the net-opening angle control plate 18. The net-opening angle control plate 18 is fixed above the net-opening actuator 15, and above the net-opening angle control plate 18 is the hook plate 17. When the inner hook 16 is fixed by bolts, the inner hook 16 can rotate around the axis of the threaded hole on the snap-fit ​​groove 26 in the snap-fit ​​groove 26 of the hook plate 17. When the net-opening angle control plate 18 rotates under the drive of the net-opening actuator 15, when the bottom of the inner hook 16 engages with the snap-fit ​​groove 26 on the net-opening angle control plate 18, the top of the inner hook 16 tilts backward, thereby releasing the hook rope 32. The spring 4 returns to its shape and pushes the end cap of the spring 4 to move outward, thereby pulling the net rope 7 and pulling the capture net out of the net box 5, ensuring the storage and unfolding effect of the capture net. like Figure 6 As shown, the inside of the net box cover 13 is provided with a connector installation interface 27, and both sides of the installation connector 27 are provided with net fixing holes 28 to fix the net. The bottom of the net box cover 13 is provided with a circular top plate 29, the main body 6 is provided with a partition 25, and the net box 13 also has a corresponding partition 25. The partition 25 is located at the top of the net box 13. During assembly, the two partitions 25 are fitted together, and the screws pass through the two partitions 25 to connect the main body 6 and the net box 5 together. The circular top plate 29 is provided with four mounting holes 30 and two positioning pin holes 31. The mounting holes 30 are used to reserve holes for screwdrivers, and the positioning pin holes 31 are used to insert positioning pins. The mounting holes 30 and positioning pin holes 31 are provided with at least two sizes to meet the installation and deployment of nets of different sizes.

[0025] In the method for opening a net using an aerial net-opening device for unmanned aerial vehicles (UAVs) according to the present invention, the net-opening actuator 15 drives the net-opening angle control plate 18 to press against the lower part of the inner hook 16, so that the inner hook 16 is in a vertical state; and tensions the hook rope 32, thereby fixing the capture net to the net box cover 13. The telescopic hook rope 32 hooks the upper part of the inner hook 16 under the action of the spring 4, so that the inner hook 16 becomes a lever mechanism in a force balance state to achieve the function of locking the rope mechanism; when the net-opening actuator 15 receives the net-opening command issued by the flight control computer, the net-opening actuator 15 drives the net-opening angle control plate; when the net-opening angle control plate 18 rotates to the bottom of the inner hook 16, the inner hook 16 tilts backward, thereby releasing the hook rope 32; after the hook rope 32 is released, the net-pulling rope 7 pulls the capture net open under the action of the spring 4 and unfolds the net, thereby completing the unfolding of the capture net.
