Description

Technical Field

[0001] The present invention relates to a drone capturing device, and more particularly to an anti-drone device and method. Background Art

[0002] As a product of modern scientific and technological development, drones have been widely used in many fields. For example, in the field of aerial photography, drones have provided great convenience for industries such as film and television production, mapping, and environmental monitoring with their flexible flight capabilities and high-resolution camera equipment. In addition, in the military field, drones also play a vital role, performing various tasks such as reconnaissance and strike, greatly improving combat efficiency and safety.

[0003] However, as the number of drones continues to increase and their use continues to expand, their potential security risks are becoming increasingly prominent. When drones fly without authorization or constraints, they may pose a serious threat to people's daily lives, privacy security, and public safety. In order to meet this challenge, people have begun to explore and study various drone interception technologies to ensure the safety and order of the airspace.

[0004] Traditional methods of intercepting drones mainly include electronic jamming and shooting down. Electronic jamming usually interferes with the flight control system or communication system of the drone by emitting electromagnetic waves of a specific frequency, causing it to lose control or be unable to communicate normally. The shooting down method is more direct, mainly destroying the drone by using guns, throwing objects, etc.

[0005] Although the shooting down method is fast and effective in some cases, it still has many shortcomings in practical application. First of all, shooting down a drone requires a certain degree of accuracy and skill, otherwise it is difficult to successfully hit the target. Whether it is shooting with a gun or throwing something manually, the operator needs to have good judgment and aiming ability. Otherwise, not only may it be impossible to effectively intercept the drone. Summary of the invention

[0006] Therefore, in order to solve the above-mentioned shortcomings, the present invention provides an anti-UAV device and method. The anti-UAV device is used in conjunction with a firearm to intercept a UAV. The bullet shot by the firearm drives the cap to fly. During the flight, the cap balances the speed difference between the bullet and the cap by rotating the bearing. At the beginning of the flight, the hook is separated from the mounting part and the flying wire is pulled out. During the continuous flight, several hooks with flying wires form an umbrella-shaped net and fly towards the UAV, thereby intercepting the UAV.

[0007] Specifically, an anti-UAV device includes a cap cover, the cap cover includes a mounting portion and a cover body portion, the cover body portion is located in front of the mounting portion, and the cap cover is sleeved on an external driving device; A rotating bearing is installed in the installation part or the cover body; A plurality of hooks are evenly arranged on the periphery of the mounting portion, and the hooks are connected to the cap sleeve through flying wires, one end of the flying wire is fixedly connected to the mounting portion, and the other end is fixedly connected to the hook; The hook is fitted on the mounting portion.

[0008] Optionally, the outer ring of the rotating bearing is fixedly connected to the inner wall of the mounting portion or the cover body, and the inner wall of the inner ring of the rotating bearing is a conical surface that matches the outer circle of the bullet head, and the small diameter side of the conical surface is close to the cover body.

[0009] Optionally, an axial through groove is provided on the inner wall surface of the inner ring of the rotating bearing.

[0010] Optionally, the mounting portion is cylindrical or has a streamlined conical surface, and the cover body is conical.

[0011] Optionally, the hook is adhered to the outer wall surface of the mounting portion through an easy-to-peel layer.

[0012] Optionally, a plurality of the hooks are evenly arranged in a circular array with the center of the mounting portion as the center.

[0013] Optionally, the flying wire of the hook is wound around the inner wall of the hook or the mounting portion.

[0014] On the other hand, the present invention provides an anti-UAV method, which is implemented by the anti-UAV device, and the specific steps of the method are as follows: Mounting the assembled anti-UAV device on the drive device port; The driving device triggers the driving block, and the driving block is inserted into the rotating bearing; The anti-UAV device flies with the driving block fired by the strike, and the cap of the anti-UAV device suit detaches from the driving device port; After the cap is separated from the device port, during the flight, the hook is separated from the mounting part, and the flying wire is pulled out. During the continuous flight, several hooks with flying wires form an umbrella-shaped net and fly toward the drone; The scattered flying silk will destroy the drone's flight state after contacting it.

[0015] Optionally, the driving device is a firearm, and the driving block is a bullet fired by a gunshot.

[0016] The present invention has the following advantages: The anti-UAV device of the present invention is used in conjunction with a firearm to intercept a UAV. The bullet shot by the firearm drives the cap cover to fly. During the flight, the cap cover balances the speed difference between the bullet and the cap cover by rotating the bearing. In the initial stage of the flight, the hook is separated from the mounting portion, and the flying wire is pulled out. During the continuous flight, several hooks with flying wires rotate to form an umbrella-shaped net that flies toward the UAV. The cap cover may rotate during the flight, and the rotating cap cover will allow several hooks with flying wires to form a larger net, thereby expanding the area for intercepting the UAV. When the propeller of the UAV contacts the flying wire, the flying wire will immediately entangle with the propeller, causing the UAV to lose its flight capability, thereby ultimately intercepting the UAV.

DETAILED DESCRIPTION

[0018] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0019] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises", or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0020] As mentioned in the background technology, traditional drone interception methods mainly include electronic jamming and shooting down. Electronic jamming usually interferes with the flight control system or communication system of the drone by emitting electromagnetic waves of a specific frequency, causing it to lose control or unable to communicate normally. The shooting down method is more direct, mainly destroying the drone by using guns, throwing objects, etc.

[0021] Although the shooting down method is fast and effective in some cases, it still has many shortcomings in practical application. First of all, shooting down a drone requires a certain degree of accuracy and skill, otherwise it is difficult to successfully hit the target. Whether it is shooting with a gun or throwing something manually, the operator needs to have good judgment and aiming ability. Otherwise, not only may it be impossible to effectively intercept the drone.

[0022] Based on the above reasons, this embodiment provides an anti-UAV device, such as Figure 1-Figure 6 As shown, the anti-UAV device includes a cap cover 100, which includes a mounting portion 101 and a cover portion 102, wherein the cover portion 102 is located in front of the mounting portion 101, and the cap cover 100 is mounted on an external drive device 500. Optionally, the drive device may be a firearm, and the cap cover is mounted on the front end of the barrel of the firearm, such as Figure 7 As shown; A rotating bearing 400 is installed in the installation portion 101 or the cover 102; Several hooks 200 are evenly arranged on the periphery of the mounting portion, and the hooks are connected to the cap sleeve 100 through flying wires 300. One end of the flying wire 200 is fixedly connected to the mounting portion 101, and the other end is fixedly connected to the hook 200 (such as Fig. 9 shown); The hook is adhered to the outer wall surface of the mounting portion through an easy-to-peel layer, and the easy-to-peel layer bonding ensures that the hook and the mounting portion can be separated during the flight of the cap.

[0023] When the above-mentioned technical features are combined with firearms, the interception of drones can be realized. The bullet shot by the firearm drives the cap cover to fly. During the flight, the cap cover balances the speed difference between the bullet and the cap cover by rotating the bearing. During the continuous flight, the hook is separated from the mounting part and the flying wire is pulled out. During the continuous flight, several hooks with flying wires form an umbrella-shaped net and fly towards the drone. The cap cover may rotate during the flight. The rotating cap cover will allow several hooks with flying wires to form a larger net, thereby expanding the area for intercepting drones. When the propeller of the drone comes into contact with the flying wire, the flying wire will immediately entangle with the propeller, causing the drone to lose its ability to fly, and finally the drone is intercepted.

[0024] In order to better balance the speed difference between the bullet and the cap, a rotating bearing is installed in the cap, and in order to allow the bullet to enter the rotating bearing better, in one embodiment, Figure 6 and Figure 7 As shown, the outer ring of the rotating bearing is fixedly connected to the inner wall of the mounting portion or the cover body, and the inner wall of the inner ring 401 of the rotating bearing is a conical surface that matches the outer ring of the bullet, and the small diameter side of the conical surface is close to the cover body.

[0025] The above technical features enable the bullet to combine with the inner ring of the rotating bearing after entering the rotating bearing, and the inner ring of the rotating bearing moves with the bullet; the bullet can be limited by the conical surface, and after the bullet enters the conical surface, the bullet and the inner ring of the rotating bearing rotate coaxially. Since the inner ring and the cap sleeve can rotate relatively, this design can balance the speed difference between the bullet and the cap sleeve, thereby reducing the influence of the cap sleeve on the flight of the bullet.

[0026] In order to discharge the air in the cap sleeve when the bullet enters the cap sleeve, an axial through groove 402 is provided on the inner wall surface of the inner ring of the rotating bearing. The axial through groove can be used to discharge the air in the cap sleeve when the bullet enters the cap sleeve, thereby avoiding the reverse force on the bullet caused by the air in the cap sleeve being squeezed and unable to be discharged, which may cause the rotating bearing to be loosely in contact with the bullet, thereby allowing the bullet to have better contact with the inner ring.

[0027] In order to improve the flying ability of the cap cover, in one embodiment, the mounting portion is cylindrical, and the cover body is conical with closed ends.

[0028] In order to enable the cap to better form an umbrella-shaped net during flight, in one embodiment, a plurality of the hooks are evenly arranged in a circular array with the center of the mounting portion as the center.

[0029] In order to better store the flying threads, in one embodiment, the flying threads of the hook are wound around the inner wall of the hook or the mounting portion, and the winding method is required to ensure that the flying threads will be taken out after the hook is detached, and the problem of mutual entanglement will not occur.

[0030] In another embodiment, the present invention provides an anti-UAV method, which is implemented by the anti-UAV device, and the specific steps of the method are as follows: Mounting the assembled anti-UAV device on the drive device port; The driving device triggers the driving block to enter the rotating bearing; The anti-UAV device flies with the driving block fired by the strike, and the cap of the anti-UAV device suit detaches from the driving device port; After the cap is separated from the device port, during the flight, the hook is separated from the mounting part, and the flying wire is pulled out. During the continuous flight, several hooks with flying wires form an umbrella-shaped net and fly toward the drone; The scattered flying threads will affect the flight of the drone after coming into contact with it.

[0031] Optionally, the driving device is a firearm, and the driving block is a bullet fired by a gunshot.

[0032] This method intercepts drones by shooting. During the design process, the area for intercepting drones is increased by dispersing the nets, thereby improving the drone interception effect.

[0033] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
