Description

Technical Field

[0001] This utility model relates to the field of capture device technology, and in particular to a drone capture device that is easy to load. Background Technology

[0002] With the rapid development of drone technology, its applications in aerial photography, logistics, security, and inspection are becoming increasingly widespread. However, along with the rapid increase in the number of drones, problems such as illegal airspace intrusion, uncontrolled flight, and equipment malfunctions are becoming increasingly prominent, posing serious challenges to public safety and management. To address this, researchers both domestically and internationally have developed various drone interception and capture devices in recent years, aiming to effectively control and capture abnormal or unauthorized drones to prevent personal injury or property damage. Among these, mechanical capture devices based on capture nets have attracted widespread attention due to their non-contact operation, fast response speed, and high safety. These devices typically use pneumatic catapults, motor drives, or other methods to rapidly deploy the capture net to intercept the target drone.

[0003] Although existing technologies have achieved capture functionality to some extent, they still have many shortcomings in practical applications. First, most existing capture devices lack an effective cutting mechanism. When the capture net accidentally gets entangled in obstacles (such as tree branches or utility poles), it cannot automatically cut and detach the net, easily causing the device to jam or even be damaged, affecting subsequent operations. Second, most devices lack the ability to adjust the height of the capture net, making it difficult to flexibly adjust according to the terrain or obstacle distribution, limiting their applicability in complex environments. Third, some capture devices have unreasonable structural designs, are cumbersome to install and disassemble, and lack portability and modularity, hindering rapid deployment in emergency scenarios.

[0004] In summary, current drone capture technology still has certain shortcomings in obstacle avoidance response, terrain adaptability, and operational flexibility. This invention provides an easy-to-load drone capture device that, by incorporating a front and rear connecting seat and integrating key components such as a lead screw mechanism, capture net reel roller, guide roller, and cutting blade, specifically solves the problem of traditional capture devices failing to cut off and detach the capture net when it becomes entangled in obstacles, thus improving the system's emergency handling capabilities. Furthermore, the device can adjust its extension height by reeling in the capture net, avoiding obstacles and enhancing adaptability and ease of operation in complex terrain. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an easy-to-load drone capture device, comprising a front connecting seat and a rear connecting seat. A lead screw device is fixedly connected to the upper part of the front connecting seat, and a capture net roller is installed on the rear connecting seat. A capture net is wound on the capture net roller. A guide roller is rotatably connected to the front connecting seat, and a placement channel is provided between the guide roller and the lead screw device. A first motor is fixedly connected to one side of the rear connecting seat, and the first motor is connected to the capture net roller through a coupling. A cutting blade is drivenly connected to the lead screw device.

[0006] The lead screw device includes a housing, inside which a lead screw is provided. The lead screw is connected to a slider via a lead screw nut, and the slider is fixedly connected to the cutting blade.

[0007] A heightening block is fixedly connected to the front connecting seat, and a second motor is fixedly connected to the heightening block.

[0008] The front and rear connecting seats are respectively provided with mounting holes, and a first bolt is connected to the mounting hole. A rubber support foot is connected to the lower part of the first bolt.

[0009] A sleeve is fixedly connected to the front connecting seat and the rear connecting seat respectively. A locking bolt is connected to the sleeve. The sleeve is used to fit onto the end of the base connecting rod at the bottom of the drone. A lithium battery is installed on the lead screw device.

[0010] The output shaft of the second motor passes through the heightening block and is connected to the end of the lead screw. The end of the lead screw is connected to a lead screw bearing seat, and the rear connecting seat is provided with a blind mounting hole.

[0011] Compared with existing technologies, the advantages of this invention are as follows: by setting a net-catching roller on the rear connecting seat, and cooperating with the guide roller and screw device on the front connecting seat, the net can be partially rolled up according to the actual terrain requirements, thereby effectively reducing the extension height of the net. This design improves the applicability of the device in complex environments such as urban streets, forests, and densely built-up areas, and avoids the net from accidentally hitting obstacles or affecting the passage of pedestrians and vehicles due to excessive height.

[0012] During the capture process, if the capture net accidentally gets tangled in obstacles such as tree branches or utility poles, the cutting blades driven by the lead screw can quickly cut the net, allowing the device to detach from the obstacle and preventing damage or interruption of the operation due to jamming. This function significantly improves the device's ability to respond to emergencies and its overall stability.

[0013] The device adopts a modular design, with the front and rear connecting seats assembling quickly via standard connectors. Rubber feet and locking bolts ensure stable mounting. Furthermore, the use of sleeves and locking bolts facilitates connection with drones, improving ease of deployment and operability. Attached Figure Description

The lead screw 13 is connected to a slider 20 through a lead screw nut. The second motor 14 is used to drive the lead screw 13 to rotate and drive the slider 20 to move. A cutting blade 21 is connected to the lead screw device 5. The slider 20 is fixedly connected to the cutting blade 21 and is used to perform a cutting operation when it gets tangled in an obstacle.

[0025] A capture net roller 12 is installed on the rear connecting seat 3, and a capture net 2 is wound on the capture net roller 12. A guide roller 4 is rotatably connected to the front connecting seat 10. A placement channel 19 for the capture net 2 to pass through is provided between the guide roller 4 and the screw device 5.

[0026] A first motor 11 is fixedly connected to one side of the rear connecting seat 3. The first motor 11 is connected to the capture net roller 12 through a coupling. The first motor 11 can drive the capture net roller 12 to rotate, thereby adjusting the extension height of the capture net 2.

[0027] A heightening block 15 is fixedly connected to the front connecting seat 10, and a second motor 14 is fixedly connected to the heightening block 15. The second motor 14 is used to drive the lead screw 13 to rotate.

[0028] Mounting holes are provided on the front connecting seat 10 and the rear connecting seat 3 respectively. A first bolt 7 is connected to the mounting hole. The first bolt 7 passes through the mounting hole. A rubber support foot 17 is connected to the lower part of the first bolt 7 to play a buffering role.

[0029] A lithium battery 6 is installed on the lead screw assembly 5 to power the second motor 14.

[0030] The output shaft of the second motor 14 passes through the heightening block 15 and is connected to the end of the lead screw 13. The end of the lead screw 13 is connected to the lead screw bearing seat 16, which plays a role in stabilizing support. The rear connecting seat 3 is provided with a blind hole 18 for placing one end of the capture net roll 12 into the blind hole 18.

[0031] Working principle: This utility model provides an easy-to-load drone capture device, mainly composed of a front connecting seat 10 and a rear connecting seat 3. The two are fixed to the end of the base connecting rod 8 at the lower part of the drone 1 by a sleeve 9. The sleeve 9 is equipped with a locking bolt to ensure a stable installation. The entire device has a compact design and is easy to load and unload quickly.

[0032] When a drone capture mission is required, the capture net 2 passes through the placement channel 19 between the guide roller 4 and the lead screw device 5, the first motor 11 is started, and the capture net winding roller 12 is rotated through the coupling, releasing the capture net 2 wrapped on it. Finally, it unfolds to form a capture area for capturing unauthorized drones.

[0033] To adapt to targets of different heights or avoid obstacles, the extension and retraction of the capture net roller 12 can be controlled by adjusting the rotation direction and speed of the first motor 11, thereby adjusting the extension height of the capture net 2.

The second motor 14 is located on the heightening block 15 and passes through the heightening block 15 via its output shaft, directly driving the lead screw 13 to rotate. A lead screw nut is installed inside the lead screw 13, which is connected to the slider 20 in a transmission manner. As the lead screw 13 rotates, the slider 20 moves along the lead screw axis, thereby driving the cutting blade 21 to move and cut the capture net 2. A lead screw bearing seat 16 is provided at one end of the lead screw 13 to provide stable support.

[0035] In addition, a lithium battery 6 is installed inside the lead screw device 5 to power the second motor 14, ensuring timely response and execution of the cutting operation under any circumstances.

The front connecting seat 10 and the rear connecting seat 3 of the entire device are respectively provided with mounting holes, connected by the first bolt 7 and equipped with rubber feet 17, which serve as a buffer to prevent damage caused by collision.

[0036] In summary, this utility model, through ingenious design, realizes the height adjustment function of the capture net 2 and the automatic cutting capability when encountering obstacles, thereby improving the adaptability and reliability of the device in complex environments and making it suitable for various drone security and interception scenarios.
