Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV capture device. Background Technology

[0002] With the rapid development and popularization of drone technology, the drone market is currently experiencing explosive growth. However, while drones bring convenience to fields such as agriculture, photography, transportation, and rescue, their "double-edged sword" nature is becoming increasingly prominent. Specifically, the misuse of drones has posed a series of serious security threats. For example, drones can easily overcome traditional physical barriers, becoming tools for spying on personal privacy, obtaining trade secrets, and even conducting illegal surveying, posing a serious privacy and security threat. Furthermore, drones may also be used to deliver contraband, carry out terrorist attacks, or serve as espionage tools.

[0003] Therefore, drone capture technology has become a focus in the field of low-altitude security. Currently, hard-kill techniques are mainly used for physical interception of low-altitude drones. These hard-kill techniques include: ① Laser weapon interception: This involves using a high-energy laser beam to shoot at the drone to intercept it. While laser weapon interception has the advantage of precision, it is greatly affected by weather conditions (e.g., rain, fog, and dust significantly reduce its effectiveness) and is costly; ② Kinetic impact interception: This involves directly ramming the drone into the target. This is a lose-lose interception method, with the advantage of being less affected by weather conditions, but its accuracy and cost are high; ③ Net interception: This is currently the most common hard-kill technique, suitable for short-range drone capture. It involves using a capture device to project a net to wrap around the drone's rotor, disabling it and achieving interception. The advantage of this method is that it can capture the drone relatively intact. This method is beneficial for subsequent evidence collection and analysis with minimal collateral damage. However, most existing capture devices currently use electric drive or the gas generated by gunpowder combustion to drive the capture net projection. The electric drive method requires the installation of a power supply and coils on the capture device (such as patent CN218847031U), which leads to complex structure, heavy weight, and high cost. The gunpowder combustion method requires the inclusion of a combustion chamber and ignition device on the capture device (such as patent CN209889115U), which also leads to complex structure, heavy weight, and high cost. Furthermore, this method requires the constant loading of gunpowder during actual use, which is inconvenient and poses safety hazards. Utility Model Content

[0004] The purpose of this invention is to design a drone capture device to solve the aforementioned problems of existing capture devices.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: This utility model designs a drone capture device, which includes the following structural configuration: The capture device body has a sealed end and a jet end, and an inflation chamber is formed inside the body that communicates with the jet end. The outside of the capture device body is also provided with an inflation nozzle that communicates with the inflation chamber and a switch that is slidably provided for controlling the release of high-pressure gas in the inflation chamber from the jet end. The launch head has a connecting end and a launching end, and a gas launching chamber is formed inside it. The connecting end and the launching end are respectively provided with a connecting nozzle communicating with the gas launching chamber and a number of inclined launching holes. The connecting nozzle is connected to the jet end. A plurality of transmitting tubes are respectively connected and disposed in the transmitting hole, and adjacent transmitting tubes form an included angle α, satisfying 10°≤α≤30°; The capture structure includes a capture net and several traction heads connected to the capture net, the traction heads being movably loaded in a launch tube and ejected by released high-pressure gas.

[0006] Specifically, the drone capture device designed in this utility model is a device that uses high-pressure gas as a power source to drive the projection of the capture net (i.e., it uses a pneumatic method to drive the projection of the capture net). Unlike the existing capture net projection method, its working principle is as follows: high-pressure gas is injected into the inflation chamber through the inflation nozzle. After the switch is turned on, the high-pressure gas is released from the inflation chamber and enters the gas launch chamber through the jet end, which in turn pushes the traction head loaded in the launch tube to project out. The traction head carries the capture net out and opens to capture the target drone.

[0007] Specifically, an external inflation device connected to the inflation nozzle can inflate the inflation chamber to form high-pressure gas. Once inflation is complete, the conditions for projecting the capture net are met, and the net can be projected after the switch is turned on. Furthermore, this invention also features an angle α between the launching tubes. By changing angle α, the angle of the traction head after projection can be adjusted, thereby changing the projection distance of the capture net (a smaller angle α is beneficial for increasing the projection distance).

[0008] Furthermore, a drone capture device is provided: the capture device body is also equipped with a pressure gauge, which is used to monitor the air pressure in the inflation chamber.

[0009] Furthermore, a drone capture device includes an anti-recoil structure, which is detachably connected to the sealed end of the capture device body. The anti-recoil structure is used to resist the recoil force generated when the capture device is launched (i.e., it can resist the recoil force generated when high-pressure gas is released). At the same time, by pressing the anti-recoil structure against the operator's body, the shaking during the capture net projection process can be reduced, which is conducive to improving projection accuracy and enhancing the drone capture precision.

[0010] Furthermore, a drone capture device includes an inflation nozzle located near the sealing end on the side wall of the capture device body; and a switch located near the jet end and slidably fitted onto the outside of the capture device body.

[0011] Furthermore, a drone capture device includes a latching structure for assisting in driving the switch to achieve an on / off action; The fastening structure includes the following structural configuration: A mounting bracket, which is perpendicular to the main body of the catcher and connected to its exterior; A drive frame, which is connected to the outside of the switch; And a latch, the middle part of which is rotatably connected to the fixed frame and the end of which is hinged to the drive frame. After the latch is engaged, the switch is slid to realize the opening / closing action.

[0012] Specifically, the design of the latch structure makes it easier to open the switch on the main body of the catcher.

[0013] In actual use, the drone capture device can be held by hand with the trigger mechanism and the recoil mechanism against the chest or shoulder. The capture net can be launched by pulling the trigger.

[0014] Furthermore, a drone capture device includes an adapter, with the nozzle and jet nozzle respectively connected to the adapter to achieve a connection between the two. That is, the adapter connects the launch head to the main body of the capture device.

[0015] Furthermore, a drone capture device includes a gas emission chamber comprising a gas distribution chamber and several conical air passages communicating with the gas distribution chamber; wherein the volume of the gas distribution chamber accounts for 15-30% of the volume of the gas emission chamber, the gas distribution chamber is connected to the connecting nozzle, one end of the air passage is connected to the gas distribution chamber, and the other end is connected to the emission port.

[0016] Specifically, the gas distribution chamber in the gas launching chamber of this invention has a small proportion, which can reduce the pressure drop of high-pressure gas in the gas distribution chamber. At the same time, the conical air passage design helps the gas maintain a high pressure when entering the launching tube, thereby facilitating the projection of the traction head (capture net).

[0017] Furthermore, a drone capture device includes a funnel-shaped net cylinder, which is disposed in a space enclosed by a plurality of launch tubes and fixed to the launch tubes by straps. The capture net is movably loaded in the net cylinder, and the traction head is movably disposed in the launch tubes.

[0018] Furthermore, a drone capture device includes a detachable cover for sealing the net tube; a pin is provided at the bottom of the net tube, and a slot is provided on the launching end, with the pin inserted into the slot to further secure the net tube.

[0019] Specifically, when not using the drone capture device, the towing head and capture net can be stored in the net tube and the lid can be fastened to the net tube.

[0020] Furthermore, in a drone capture device, a slot for tightening the launch tube is provided at the end of the launch tube away from the launch hole.

[0021] The beneficial effects of this utility model are: The core advantage of this drone capture device lies in its use of high-pressure gas generated by inflation to provide the power for projecting the capture net, thus abandoning the traditional methods of electric drive or gunpowder combustion. This simplifies the device's structure and reduces operating costs, overcoming the problems of complex structure, heavy weight, and high cost associated with existing capture devices. Furthermore, this newly designed drone capture device allows for rapid inflation, making it ready to use immediately. The high-pressure gas released during inflation provides a more stable power output compared to the explosive power of gunpowder combustion, with less recoil and improved accuracy in net projection, making it easier to capture target drones. Additionally, the high-pressure gas power source generated by inflation is safer than power sources generated by gunpowder combustion.

[0022] This invention relates to a drone capture device that incorporates a locking mechanism and a recoil mechanism on the main body of the capture device. This allows the operator to project the capture net in a more effortless and easier-to-aiming manner during actual use, thereby improving the capture rate of the target drone.

[0023] The UAV capture device designed in this utility model also features a smaller gas distribution chamber, which can effectively reduce the pressure drop of high-pressure gas in the gas distribution chamber. At the same time, the conical air passage design allows the released gas to maintain a higher pressure when entering the launch tube, thus retaining more of the high-pressure gas's own power, which is beneficial for pushing the traction head to launch.

[0029] Example 1 like Figures 1-5 As shown in the figure, this embodiment 1 designs a drone capture device, which includes the following specific structural configuration: The capture device body 1 is cylindrical in shape, with a sealing end 11 and a jet end 2. An inflation chamber 13 communicating with the jet end 12 is formed inside. An inflation nozzle 14 communicating with the inflation chamber 13 is located on the outer sidewall of the capture device body 1 near the sealing end 11. A switch 15 for controlling the release or non-release of high-pressure gas in the inflation chamber 13 is slidably fitted on the outer side of the capture device body 1 near the jet end 12. A pressure gauge 16 is also located on the capture device body 1 near the sealing end 11 to monitor the inflation pressure in the inflation chamber 13. A recoil-resistant structure 5 is detachably connected to the sealing end 11 to resist the recoil force generated when high-pressure gas is released and to improve projection accuracy. An external fastening structure 6 is also provided on the body of the catcher 1, which is used to assist the drive switch 15 to slide on the body of the catcher 1 to realize the opening / closing action (that is, to control the release or non-release of high-pressure gas in the inflation chamber 13, similar to the existing structure of a switch sliding on the outside of the body of the catcher 1). The fastening structure 6 includes a fixed frame 61, a drive frame 62 and a fastening mechanism 63. The fixed frame 61 is connected to the outside of the catcher body 1 in a manner perpendicular to it, and the drive frame 62 is also connected to the outside of the catcher body 1 in a manner perpendicular to it. The middle part of the fastening mechanism 63 is rotatably connected to the fixed frame 61, and the end is hinged to the drive frame 62. At this time, by fastening the fastening mechanism 63, the switch 15 can be driven to slide on the body of the catcher 1, thereby realizing the opening / closing action. The launch head 2 has a connecting end 21 and a launching end 22, and a gas launching chamber 23 is formed inside it. The connecting end 21 and the launching end 22 are respectively provided with a connecting nozzle 24 communicating with the gas launching chamber 23 and a plurality of inclined launching holes 25. The connecting nozzle 24 is threadedly connected to one end of the adapter 7 and communicates with it. The other end of the adapter 7 is threadedly connected to the jet end 12 of the capture device body 1 and communicates with it. That is, the capture device body 1 and the launch head 2 are connected through the adapter 7. The gas launching chamber 23 includes a gas distribution chamber 231 and a plurality of conical air passages 232 communicating with the gas distribution chamber 231. The volume of the gas distribution chamber 231 accounts for 15 to 30% of the volume of the gas launching chamber 23. The gas distribution chamber 231 is connected to the connecting nozzle 24. The two ends of the air passages 232 are respectively connected to the gas distribution chamber 231 and the launching holes 25. A plurality of emitting tubes 3 are threadedly connected to and communicate with the emitting hole 25. An included angle α is formed between adjacent emitting tubes 3, and the angle α satisfies 10°≤α≤30°. A slot 31 is provided on the end of the emitting tube 3 away from the emitting hole 25. By inserting a tightening device (similar to a wrench) into the slot 31, the emitting tube 3 can be tightened into the emitting hole 25. The capture structure 4 includes a capture net 41 and several traction heads 42 connected to the capture net 41. The traction heads 42 are movably loaded in the launch tube 3 and are driven by the released high-pressure gas as a power source to eject the traction heads 42 out of the launch tube 3. And a net cylinder 8, which is configured as a trumpet-shaped structure, is set in a space surrounded by several launching tubes 3 and is fixed to the launching tubes 3 by straps 9. The net cylinder 8 is used to load a capture net 41. After the traction head 42 is sprayed out, it drives the capture net 42 placed in the net cylinder 8 to be projected together to capture the target drone. The net cylinder 8 is also detachably provided with a box cover 10 for sealing the net cylinder 8. The bottom of the net cylinder 8 is also provided with a pin 81, and the launching end 22 is provided with a slot 26. The pin 81 can be inserted into the slot 26 to further fix the net cylinder 8.

[0030] When using the drone capture device designed in Embodiment 1 above: First, gas is injected into the inflation chamber 13 through the inflation nozzle 14 to a predetermined pressure to form high-pressure gas. Then, the capture device is aimed at the target drone, and the latch 63 is pulled to open the switch 15. At this time, the high-pressure gas is released and enters the launch tube 3, which in turn pushes the traction head 42 loaded in the launch tube 3 to be launched. The traction head 42 carries the capture net 41 out and opens to capture the target drone.

[0031] When using the capture device again for drone capture, a new capture structure 4 (including capture net 41 and towing head 42) can be selected and loaded into the launch tube 3 and net tube 8. At the same time, high-pressure gas is refilled into the inflation chamber 13 for the next capture operation. The drone capture device designed in Example 1 can achieve rapid inflation, is ready to use immediately after inflation, and is more convenient to use. The captured net 41 can also be recovered and reused after deployment, further reducing the cost of use.

[0032] The above embodiment 1 also designs an angle α between the launch tubes 3. By changing the angle α, the angle after the traction head 42 is projected can be adjusted, thereby changing the projection distance of the capture net 41. A smaller angle α is beneficial to increasing the projection distance of the capture net 41. For target drones that are far away, different launch heads 2 can be selected so that the angle α of the launch tubes 3 connected to them is smaller, thereby dealing with the relatively far drone capture distance.

[0033] The above-described preferred embodiments of this utility model are for illustrative purposes only and are not intended to limit the scope of this utility model. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
