Abstract
Description
Technical Field
[0001] This invention belongs to the field of drone capture technology, and more specifically, it relates to a capture and interception device for aerial drones and its usage method. Background Technology
[0002] In recent years, consumer and industrial drones have rapidly gained popularity, playing a vital role in aerial surveying, logistics, and agricultural protection. However, the phenomena of unauthorized and reckless drone flights have also become increasingly prominent. Illegal drones intruding into sensitive areas such as airport airspace, military restricted areas, and security airspace for large-scale events not only disrupt the normal takeoff and landing of civil aviation flights and leak classified information, but may also cause collisions, crashes, and other safety accidents, posing a serious challenge to public safety and airspace management.
[0003] Traditional physical capture solutions often employ a "high-flying net" model, where a capture net is mounted on a drone, and operators manually approach and release the net to the target. However, this approach suffers from several technical drawbacks: First, the recoil generated during net launch can easily cause the drone to become unstable, deviating from its aiming trajectory and reducing the capture success rate. Second, the lack of an effective retraction and control mechanism after release makes the net prone to entanglement with the drone's rotor, posing a flight safety hazard. Third, traditional capture nets have a simple structure and insufficient restraint on the drone's propellers, allowing the target to easily escape or fall and be damaged. Fourth, the fixed size of the device makes it difficult to flexibly adapt to different operational scenarios such as narrow streets and open airspace, resulting in poor versatility.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a capture and interception device for aerial drones and its usage method, in order to achieve a more practical and valuable purpose. Summary of the Invention

A winding roller is fixedly installed at the front end of the winding motor. An isolation plate is provided through the middle of the winding roller. An inlet through-hole partition is fixedly connected to the end of the isolation plate. The inlet through-hole partition is in contact with the rubber base.
[0012] In a further technical solution, the turret device includes an extension base fixedly installed below the rotating base, an equipment mounting seat fixedly connected to the end of the extension base, a visual inspection device provided at the connection between the extension base and the equipment mounting seat, and a spraying assembly fixedly connected to the lower end of the extension base.

The hanging rope is connected to the winding roller and realizes lifting and winding.
[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention discloses an aerial capture and interception device for unmanned aerial vehicles (UAVs). By integrating a UAV net capture and attitude stabilization module with a venting nozzle, it achieves a closed-loop collaborative mechanism from launch to attitude stabilization to depressurization. The device synchronously triggers the capture net collection and launch unit and the high-pressure gas attitude stabilization unit via a flight control linkage module. At the moment the capture net is launched at high speed, a reverse airflow is precisely injected to counteract the recoil, preventing pitch and roll deviations and ensuring stable aiming trajectory and flight attitude. Simultaneously, after launch, the venting nozzle is immediately activated to release residual high-pressure gas within the module. This avoids high-pressure buildup that could damage launch valves, gas tanks, and other components, extending equipment lifespan, and eliminates residual gas interference to ensure continuous execution of multiple interception missions. Ultimately, this achieves the dual effect of deep coupling between core interception functions and flight attitude stabilization, and significantly improved launch operation reliability.
[0017] This invention discloses a capture and interception device for aerial drones. It establishes a coordinated system from attitude sensing to dynamic winding and then to precise restraint using an attitude sensor and a winding mechanism. The attitude sensor collects real-time flight data of the drone and provides feedback on environmental and equipment statuses such as wind speed and aircraft tilt. This data is simultaneously transmitted to the winding mechanism control module, driving the winding motor to flexibly adjust its speed and achieve dynamic winding of the lanyard. This avoids tangling and knotting of the lanyard due to uneven winding speed, ensuring smooth operation of the winding mechanism. Furthermore, the real-time fine adjustment of the winding tension helps balance the aircraft's attitude, echoing the previous attitude stabilization effect. Simultaneously, the winding mechanism's winding action pulls a hexagonal rectangular net to precisely cover the target. Circular holes on the net's surface guide the unauthorized drone's propeller into the restraint area, while the flexible filaments on the inner side form multiple layers of entanglement. This, in conjunction with the lanyard winding tension, strengthens the restraint on the target, preventing escape. The coordinated force between the net and the lanyard also prevents secondary interference from target swaying on the aircraft's attitude. Ultimately, this results in a deep synergy between flight attitude control and target capture actions, significantly improving capture success rate and stability.

The capture net assembly 5 is used to capture illegal drones in the air. The winding device 3 achieves dynamic adjustment of flight attitude and tightening in the air by winding the capture net assembly 5. This can effectively avoid the risk of the capture net assembly 5 getting tangled in the rotor of the drone due to slack. At the same time, by real-time control of the winding tension, the drone's flight attitude is kept stable, and the control precision during the capture process is improved. The turret device 4 is used to launch the capture net assembly 5. The turret device 4 is equipped with a jet assembly 6. The jet assembly 6 is used to counteract the impact force in the opposite direction when launching the capture net assembly 5, so as to ensure the stable flight attitude of the UAV body 1.

An extension push rod 24 slides within the fixed sleeve 28, and the end of the extension push rod 24 is fixedly connected to a brushless motor 25. The telescopic motor 27 drives the extension push rod 24, which in turn drives the brushless motor 25 and the extension arm 23 to extend and retract, allowing for flexible adjustment of the UAV's unfolded dimensions. During takeoff, the UAV's size is reduced for easier storage and transport; during interception, the size is increased to improve flight stability and capture coverage, achieving a multi-functional design.

A winding mechanism 7 is fixedly installed inside the fixing cylinder 31. The rubber base 33 can buffer the vibration of the winding mechanism 7 during operation, reduce equipment noise and mechanical wear, extend the service life of the device, and at the same time avoid the risk of breakage caused by hard friction between the hanging rope 56 and the opening of the fixing cylinder 31 during the winding process.
[0033] Preferred options are shown in the appendix. Figure 10The winding mechanism 7 includes a winding motor 71, which is fixedly installed inside the fixed cylinder 31.

The coordinated design of the compensating nozzle 62 and the venting nozzle 64 allows for precise control of the injection direction and flow rate of the high-pressure gas, effectively counteracting the recoil during net launch. The venting nozzle 64 can quickly release residual gas, preventing high-pressure gas buildup from affecting subsequent launch actions.
[0036] Preferred options are shown in the appendix. Figure 9 and appendix Figure 10The integrated UAV net capture and attitude stabilization module includes a net storage and launch unit and a high-pressure gas attitude stabilization unit. The net storage and launch unit includes a storage compartment, a launch valve, a guide nozzle, and a folding net. The high-pressure gas attitude stabilization unit includes a high-pressure gas tank, an electrically controlled pressure reducing valve, a solenoid valve assembly, a directional compensation nozzle, and a pressure sensor. This integrated module combines capture and attitude stabilization functions. Through precise control of the electrically controlled pressure reducing valve and pressure sensor, it achieves a constant output of high-pressure gas. The coaxial symmetrical layout of the directional compensation nozzle ensures uniform thrust. Combined with the linkage control of the flight control system, it achieves synchronous triggering of net launch and attitude compensation, increasing the interception success rate by over 80%.
[0037] Preferred options are shown in the appendix. Figure 11 The capture net assembly 5 includes a hanging rope 56, on which a ball 54 is slidably mounted. The ball 54 has hanging holes 55, and a hexagonal rectangular net 51 is fixedly installed between the balls 54. The surface of the hexagonal rectangular net 51 has a rectangular array of several sets of circular holes 52, and the inner side of each circular hole 52 has flexible filaments 53. The hanging rope 56 is connected to the winding roller 73 and can achieve lifting and winding. The structural design of the hexagonal rectangular net 51 can improve the structural strength and deployment stability of the capture net. The circular holes 52, combined with the flexible filaments 53, can form multiple entanglements and restraints on the propellers of illegal drones, preventing them from escaping. The balls 54 can increase the launch weight of the capture net, improve the stability of the flight trajectory, and effectively avoid capture deviation caused by wind interference. Simultaneously, the lifting and winding design of the hanging rope 56 allows for length adjustment after capture to prevent the illegal drone from falling and being damaged.
[0038] Specific usage of this invention: When using this device to intercept and capture illegal drones in the air, the operator first establishes a stable connection with the satellite communication module 13 on top of the drone body 1 via a handheld communication terminal. This module supports dual-mode communication via satellite and Wi-Fi, ensuring real-time transmission of control commands and accurate feedback of equipment status even in harsh environments such as urban high-rise buildings blocking the way or complex electromagnetic interference, thus avoiding the risk of mission failure due to signal interruption. Before takeoff, the device's size can be flexibly adjusted according to the actual operational scenario, such as deployment in confined spaces or long-distance, large-area interception. By activating the telescopic motor 27 inside the equipment component box 21, its output end drives the extension push rod 24 inside the fixed sleeve 28 to extend forward, thereby pushing the extension arm 23 to slide along the fixed arm 22, so that the brushless motor 25 at the end and the winding device 3 expand outward synchronously. At this time, the unfolding range of the machine body is expanded. Combined with the hexagonal container-shaped equipment housing 11 and the rectangular extension part 12 on the outer side of the hexagon, the flight stability and the coverage area of the capture net can be significantly improved. For portable storage or takeoff in confined spaces, the retractable motor 27 can be controlled to retract, which in turn drives the extension arm 23, extension push rod 24, and brushless motor 25 to retract, reducing the size of the aircraft and achieving the effect of "one machine adapting to multiple scenarios". After the size adjustment is completed, the brushless motor 25 starts, driving the propeller blades 26 at the output end to rotate at high speed to generate lift. Since the brushless motor 25 and the winding device 3 adopt a counter-oriented structural design, the weight load of the winding device 3 can be effectively balanced, avoiding flight tilt caused by unilateral weight imbalance. At the same time, the high power density of the brushless motor 25 can quickly respond to the takeoff and landing commands, enabling the device to take off smoothly and quickly reach the preset interception airspace.
[0039] After the device is launched, the operator activates the interception mode via a handheld communication terminal. At this time, the rotating base 41 at the bottom of the turret device 4 begins to operate, driving the extension base 42 and the equipment mounting base 43 at the end to achieve a 360° omnidirectional rotation. Combined with the visual detection device 44 at the connection between the extension base 42 and the equipment mounting base 43, it can perform an all-round scan of the surrounding airspace, identify and accurately locate illegal drones, solving the technical pain points of traditional fixed turrets, such as limited interception angles and low target acquisition efficiency. Once the visual detection device 44 locks onto the illegal drone and completes aiming calibration, the operator issues a launch command, and the integrated drone netting and attitude stabilization module inside the filling sleeve 63 immediately enters working mode. As the core execution unit, this module seamlessly integrates the capture net storage and launch unit with the high-pressure gas attitude stabilization unit through a flight control linkage module and power supply control circuit, ensuring synchronized actions. In the capture net storage and launch unit, the launch valve opens rapidly upon receiving a command, and the high-pressure gas instantly propels the folded capture net inside the storage compartment out at high speed along the guide nozzle. The net rapidly unfolds under the action of air resistance. At the same time, the high-pressure gas attitude stabilization unit responds synchronously. The pressure sensor monitors the gas pressure data in the high-pressure gas tank in real time and feeds it back to the electronically controlled pressure reducing valve for precise regulation to ensure that the output gas pressure is constant. Under the control of the flight control linkage module, the solenoid valve group drives the directional compensation nozzle and the compensation jet nozzle 62 in the jet assembly 61 to spray high-pressure gas in the opposite direction of the capture net, forming a uniform and stable reverse thrust, which accurately counteracts the recoil generated when the net is launched, and completely solves the problem of drone instability and deviation from the aiming trajectory caused by recoil in traditional capture devices.
[0040] After launch, the vent nozzle 64 at the front end of the filling sleeve 63 quickly releases the residual gas inside the tank, preventing high-pressure gas buildup from damaging internal components of the module and reserving a safe space for possible secondary launches. During the flight and target contact of the capture net, the attitude sensor inside the device housing 11 monitors the device's flight dynamics in real time and transmits the data synchronously to the flight control system. The flight control system then activates the winding mechanism 7 within the winding device 3. The winding motor 71 adjusts its operating speed according to the posture data, driving the front winding drum 73 to rotate at a constant speed, and winding the hanging rope 56 connected to the drum in real time. The partition plate 72 in the middle of the winding drum 73 divides the drum into two independent winding sections, which can respectively correspond to the multiple sets of hanging ropes 56 of the capture net assembly 5, effectively preventing the hanging ropes from crossing, tangling, or knotting; the wire inlet through hole partition plate 74 fits against the rubber base 33 at the bottom of the fixed cylinder 31, which not only guides and limits the hanging ropes 56 to ensure that the tension is evenly distributed during the winding process, but also reduces the vibration and noise of the winding mechanism during operation through the buffer characteristics of the rubber base, reduces mechanical wear, and extends the service life of the equipment.
[0041] When the hexagonal rectangular net 51 reaches the location of the illegal drone under the traction of the hanging rope 56, the circular holes 52 distributed in a rectangular array on the surface of the net first guide the propeller of the illegal drone into the net area. Then, the flexible filaments 53 inside the circular holes 52 quickly wrap around the propeller blades to form a multi-binding structure. Compared with the traditional single hanging net, this design can greatly improve the binding firmness and effectively prevent the illegal drone from breaking free by the high-speed rotation of the propeller. Meanwhile, the rolling ball 54, which slides on the hanging rope 56, plays a role in increasing the weight and stabilizing the trajectory during the net launching process. It can resist interference from medium and low wind speeds, avoid deviation of the net's flight trajectory, and ensure accurate hit on the target.
[0042] Once the illegal drone is stably entangled and bound, its flight power is completely restricted by the flexible filaments 53 and the hexagonal rectangular net 51. At this time, the operator can observe the status of the equipment in real time through a handheld communication terminal. Based on the weight of the illegal drone and the wind conditions in the current airspace, the operator can dynamically adjust the operating speed of the winding motor 71, thereby controlling the length of the hanging rope 56: if the wind is strong or the illegal drone is too heavy, the length of the hanging rope can be shortened appropriately, and the connection stability between the device and the target can be improved by the winding tension to prevent the target from swaying and causing the device to lose its attitude; if stable transportation is required, the hanging rope should be kept moderately slack to avoid excessive tension causing additional damage to the illegal drone.
[0043] Throughout the transportation process, the real-time winding of the reeling device 3 and the attitude control of the flight control system work in concert. The dynamic balance of the lanyard tension counteracts the impact of the target weight on the device's flight. Combined with the continuous power output of the brushless motor 25 and the fine-tuning of the propeller blades 26, the device maintains stable flight, ultimately safely transporting the captured illegal drone to the designated recovery area, completing the entire process from "target identification – precise interception – stable capture – safe recovery." Throughout this process, the coordinated operation of all components not only solves the problems of attitude instability, low capture success rate, and poor scene adaptability inherent in traditional interception devices, but also achieves efficient, safe, and flexible aerial interception and capture effects through integrated design and precise control.
