Description

Technical Field

[0001] This invention belongs to the field of unmanned aerial vehicle (UAV) application and countermeasure technology, specifically relating to the field of UAV capture technology. More specifically, this invention relates to a UAV capture net projection device. Background Technology

[0002] In recent years, civilian and consumer-grade drone technology has developed rapidly, with costs continuously decreasing. Its applications have permeated numerous fields, including aerial photography, geographic surveying, agricultural and forestry protection, logistics and distribution, emergency rescue, and public safety. However, the widespread adoption of this technology has also brought significant security and management challenges. Incidents of unauthorized or maliciously operated drones intruding into sensitive airspace such as airport airspace, military control zones, government offices, nuclear facilities, large event venues, and critical infrastructure have occurred frequently, posing a real and urgent threat to aviation safety, public safety, personal privacy, and even national security.

[0003] To counter these threats, physical interception and capture technologies, particularly those that disable target drones by launching capture nets, have demonstrated unique advantages among various countermeasures. Compared to soft-kill or hard-kill methods such as radio signal jamming, GPS spoofing, or lasers, physical capture schemes have a direct mechanism of action, intuitive and controllable effects, and typically do not cause permanent damage to the target drone's electronic equipment. They also avoid secondary safety risks and property losses caused by the target crashing out of control. Therefore, they are widely considered an ideal choice for non-lethal disposal at close to medium range.

[0004] Currently, the implementation of drone-based net-capturing systems mainly relies on two technological approaches: First, as disclosed in Chinese patent document CN202323018045.5, a drone net-capturing system based on compressed air. The advantage of this technology is its ability to provide significant initial thrust and acceleration. However, its inherent limitations severely restrict its practicality on lightweight platforms, and the limited gas capacity severely restricts the number of launches (usually only a single launch or a few launches), resulting in poor rapid reloading capability.

[0005] Secondly, consider the centrifugal rotary projectile device scheme disclosed in Chinese patent application CN202410858323.8. To achieve sufficient centrifugal projectile force, the system must integrate a high-power motor, high-speed bearings, and a precision clutch or release mechanism, resulting in an exceptionally complex mechanical structure and high manufacturing and maintenance costs. The system requires a long acceleration preparation time from startup to reaching the rated projectile speed, exhibiting slow response and difficulty in dealing with sudden, rapid threats.

[0006] Existing technologies for deploying drone-to-hunt nets suffer from complex air circuits or high-speed rotating mechanisms, leading to numerous potential failure points, poor environmental adaptability, and difficult maintenance. High-value consumables or cumbersome reloading processes result in high costs per use and slow operational cycles. These long-standing technological bottlenecks severely hinder the large-scale deployment and application of efficient, low-cost drone countermeasure equipment. Summary of the Invention

[0007] Based on the aforementioned background technology, there is a need for a drone capture net deployment technology solution that features stable launch process, high reliability, low cost, and rapid reloading. This solution should achieve simplified device structure, high reliability, low cost, and convenient reusability, thus adapting to lightweight platforms such as drones and meeting the growing practical needs of applications in security patrols, key area defense, and other scenarios.

[0008] To address the aforementioned issues, this invention provides a drone-based net-capturing projection device: comprising a projectile, a guide channel, an energy storage component, and an excitation component. The projectile has a fixed terminal at its front end connected to the capture net and a locking component at its rear end that matches the excitation component. The projectile is nested within the energy storage component and placed within the guide channel, with the tail-end locking component locking to the excitation component. The projection device is deployed on the base at an angle to the plane of the base shell; this angle is adjustable. The excitation component of the projection device faces an excitation groove in the center of the base. An excitation disk is embedded in the excitation groove, and the excitation disk has an excitation end facing the excitation component within the excitation groove.

[0009] The projectiles are deployed on the substrate, with at least two projectiles projecting in different directions.

[0010] The excitation component and the guide channel are integrally formed, or the excitation component and the guide channel are connected by a detachable structure.

[0011] The outer contour of the projectile's front end is streamlined. The mating part between the projectile's end engagement component and the firing assembly consists of a set of grooves and flanges.

[0012] Energy storage components store and release energy through their own elastic deformation.

[0013] The above technical solution offers the following advantages: High system reliability and low cost: The power source utilizes extremely mature and reliable components such as mechanical springs, completely eliminating complex, leak-prone air passages, easily worn high-speed rotating parts, and high-precision valves. The entire system has a simple structure, fewer parts, strong environmental adaptability, and a low failure rate. Furthermore, it can be quickly recovered and reused hundreds of times, making the operating cost of a single interception operation far lower than existing technical solutions.

[0014] The entire process of using the device (loading, mounting, triggering, and recovery) is simple and intuitive, requiring no specialized tools or complex training. Reloading after launch is quick and easy, enabling the device to return to combat readiness in a short time, making it ideal for security applications that require continuous patrol and interception missions.

[0015] Basically, any device can be constructed to generate the launch action. Any elastic energy storage element can be used. In practice, elastic energy storage elements considered include one of the following: helical springs, leaf springs, torsion springs, elastic ropes, or energy storage elements made of elastic polymers.

[0020] The technical solution of the present invention will now be clearly and completely described with reference to the embodiments shown in the accompanying drawings.

[0021] Figures 1 to 4 The present invention provides an embodiment specifically equipped with four drone capture net projection devices.

[0022] The device is installed in four directions on the base. When the device is inserted and pushed all the way in, the locking mechanism at the tail end of the projectile locks itself to the excitation assembly. The excitation assembly, under its own elastic restoring force, makes a "click" to complete the locking. The energy storage assembly is compressed to the energy storage state. When the disc rotates, the four hemispherical protrusions on the excitation disk accurately press against the excitation assembly, applying a uniform radial outward thrust to the four excitation assemblies. This causes them to elastically bend and deform, unlocking the excitation assemblies on their inner sides, and the projectile is then ejected along the guide channel.

[0023] The moment the lock is released, the four compressed energy storage components are simultaneously released. The elastic potential energy is mainly converted into the kinetic energy of the projectiles. The four projectiles are launched synchronously at similar speeds along the pre-adjusted tilt angle, dragging the four corners of the capture net by the traction ropes. The net is completely pulled out in a very short time.

[0024] After a single launch, ground personnel can easily recover the landed projectile and capture net. The projectile can be reused after inspection; the capture net can be folded and reloaded after being organized. The energy storage components can be replaced if fatigued. The entire reloading process can be completed by a single person within 2 minutes, and the device will then be fully operational and ready to launch again.
