Description

Technical Field

[0001] The present invention relates to the technical fields of structural mechanics and explosion mechanics, and particularly relates to a dual-mode UAV countermeasure device. Background Technique

[0002] There are various methods for UAV countermeasures, mainly including: interference means including radio frequency interference guns and electromagnetic interference, physical interception means including capture nets, laser destruction and missile strikes, and software defense means including deception control. Among them, physical interception is widely concerned as one of the main countermeasure means. On the one hand, fire weapons can be used to strike UAVs. Rockets, ground-based light missiles, and air-to-air light missiles can achieve destructive strikes on target UAVs. This method can generally be used to implement emergency countermeasures and strikes on important suspicious UAVs in the peripheral areas of relatively important large-scale event security and government head escort scenarios. However, this interception and strike method is costly and poses a safety hazard to ground targets. Under non-emergency situations, this method should be used with caution.

[0003] To capture small UAVs with a flying net, CN102374826A discloses an anchor-hanging drag parachute type interception aircraft equipment without collateral damage. The anchor-hanging drag parachute type interception aircraft equipment without collateral damage includes small streamers, parachutes, parachute tying buckles, pins, a wire shaft with a central shaft hole, fiber filament bundles, interception anchors, and streamers. There is a through hole at the end of the pin. The interception anchor includes a tether hole, an anchor hook, and a ring. Each end of the anchor hook of the interception anchor is provided with a plurality of spikes, and the anchor hook can be a curved hook or a straight hook. After the control system issues an ignition command, the electric igniter is powered on and the ignition charge ignites, igniting the gas generating agent. The gas generating agent burns to produce a large amount of gas. After the large amount of gas passes through the primary homogenization and secondary homogenization of a specially designed pressure equalization structure, it reaches the cavity of the driving device with a film. When the pressure reaches the film-breaking pressure, the film ruptures, and the driving pressure acts on the bottom of the driving device structure. After adjusting the pressure through the bottom structure, the capture net is driven to fly out. This invention has the advantages of small size, light weight, and reliable operation, etc. However, the countermeasure means for UAVs is single, the gas driving force is relatively weak, and the speed of generating high-pressure gas by burning the agent is slow and the response time is long, which will affect the success rate of capturing the target UAV. Summary of the Invention

[0004] The purpose of the present invention is to provide a dual-mode UAV countermeasure device to solve the problems raised in the above background technique.

[0005] To achieve the above object, the present invention adopts the following technical solutions: A dual-mode UAV countermeasure device, comprising: a bottom case, a connecting member is installed inside the bottom case, an explosive transmission network board is installed inside the bottom case, a panel is installed inside the explosive transmission network board, a first prefabricated groove is formed on the surface of the panel, a second prefabricated groove is formed on the surface of the panel, a first charge groove is equidistantly formed on the bottom circumference of the inner wall of the explosive transmission network board, a second charge groove is equidistantly formed on the bottom circumference of the inner wall of the explosive transmission network board, and a flying net is arranged at the bottom of the explosive transmission network board.

[0006] As a preferred embodiment, the shape of the first prefabricated groove is a circular groove, and the shape of the second prefabricated groove is a linear groove.

[0007] As a preferred embodiment, a first charge hole is formed on the inner wall of the first charge groove, and a second charge hole is formed on the inner wall of the first charge groove.

[0008] As a preferred embodiment, a charge port is formed on the surface of the first charge groove.

[0009] As a preferred embodiment, the shape of the second charge groove is a linear groove, and a third charge hole is formed at the middle position of the second charge groove.

[0010] As a preferred embodiment, mass blocks are equidistantly installed on the circumference of the surface of the explosive transmission network board, and mounting blocks are fixedly installed at the bottoms of the mass blocks.

[0011] As a preferred embodiment, an included angle is formed between the mass block and the normal direction of the explosive transmission network board.

[0012] As a preferred embodiment, the other end of the mounting block is installed with a connecting wire through a bolt, and the other end of the connecting wire is fixedly installed on the surface of the flying net.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In the present invention, by exciting the charges inside the first charge groove and the second charge groove, the panel installed inside the explosive transmission network board is opened. Through the first prefabricated groove and the second prefabricated groove formed on the surface of the panel, the panel forms high-speed fragments flying in a specific direction to strike and counter the UAV, making the device more perfect.

[0014] 2. In the present invention, the mass blocks are evenly installed on the outer circumference of the detonation transfer network board. The mounting blocks at the bottoms of the mass blocks are connected to the flying net through connecting wires. When the detonation signal is transmitted to the outer circumference of the detonation transfer network board, the mass blocks pull the flying net out to capture the unmanned aerial vehicle (UAV), enabling the device to achieve the dual countermeasure effects of striking and capturing. When facing a single target UAV, the flying net can capture the UAV that has not been shot down by the fragments, improving the countermeasure efficiency. When facing a group of UAVs, the flying net can also capture the subsequent UAVs after the front UAV has been shot down by the fragments, expanding the countermeasure target range and making the device more perfect.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-4 , the present invention provides a technical solution: a dual-mode UAV countermeasure device, including: a bottom shell 1, a connecting piece 2 is installed inside the bottom shell 1, a detonation transfer network board 3 is installed inside the bottom shell 1, a panel 4 is installed inside the detonation transfer network board 3, a first prefabricated groove 401 is provided on the surface of the panel 4, a second prefabricated groove 402 is provided on the surface of the panel 4, a first charge groove 5 is equidistantly provided on the bottom circumference of the inner wall of the detonation transfer network board 3, a second charge groove 6 is equidistantly provided on the bottom circumference of the inner wall of the detonation transfer network board 3, and a flying net 10 is provided at the bottom of the detonation transfer network board 3.

[0019] Specifically: When the device is in use, charges are loaded into the charge grooves 1 - 5 and 2 - 6 formed inside the detonating network board 3. Then, when the device receives a countermeasure signal, the charges installed inside the charge grooves 1 - 5 and 2 - 6 are electrically excited through the connecting piece 2 installed inside the bottom case 1, so that the charges transfer the detonation energy, causing the panel 4 installed inside the detonating network board 3 to open, forming high - speed fragments that scatter in a directional manner. When the fragments are formed, they crack through the pre - formed grooves 1 - 401 and 2 - 402 on the surface of the panel 4, causing the fragments to scatter along a preset path, forming damage elements with directional killing effects to counter the UAV. The UAV is captured by the fly net 10 arranged at the bottom of the detonating network board 3, enabling the device to achieve the dual - mode UAV countermeasure effect of superimposing strikes and captures, making the device more perfect.

[0020] In one embodiment, the shape of the pre - formed groove 1 - 401 is a circular groove, and the shape of the pre - formed groove 2 - 402 is a linear groove.

[0021] Specifically: Since the shape of the pre - formed groove 1 - 401 is a circular groove and the pre - formed groove 2 - 402 is a linear groove, the panel 4 can scatter better when broken, counter the UAV better, and make the device more perfect.

[0022] In one embodiment, a charge hole 1 - 501 is formed on the inner wall of the charge groove 1 - 5, a charge hole 1 - 502 is formed on the inner wall of the charge groove 1 - 5, and a charge port 503 is formed on the surface of the charge groove 1 - 5.

[0023] Specifically: Through the charge holes 1 - 501 and 1 - 502 formed on the surface of the charge groove 1 - 5, the charges can be loaded into the device through the charge holes 1 - 501 and 1 - 502. Through the charge port 503 formed on the surface of the charge groove 1 - 5, the charges loaded through the charge holes 1 - 501 and 1 - 502 can enter the interior of the charge groove 1 - 5 where the charge holes 1 - 501 and 1 - 502 are not formed, making the charging effect better and making the device more perfect.

[0024] In one embodiment, the shape of the charge groove 2 - 6 is a linear groove, and a charge hole 2 - 601 is formed at the middle position of the charge groove 2 - 6.

[0025] Specifically: Through the charge hole 2 - 601 formed at the middle position of the charge groove 2 - 6, the charges can enter the interior of each charge groove 2 - 6 during charging, making the charging more convenient and making the device more perfect.

[0026] In one embodiment, mass blocks 7 are equidistantly installed on the circumferential surface of the booster network board 3. An installation block 8 is fixedly installed at the bottom of the mass block 7. The mass block 7 forms an angle with the normal direction of the booster network board 3. The other end of the installation block 8 is installed with a connecting wire 9 through a bolt, and the other end of the connecting wire 9 is fixedly installed on the surface of the flying net 10.

[0027] Specifically: by evenly installing the mass blocks 7 on the outer circumference of the booster network board 3, the installation block 8 fixedly installed at the bottom of the mass block 7 is installed at one end of the connecting wire 9 through a bolt, and the other end of the connecting wire 9 is fixedly installed on the surface of the flying net 10. When the detonation signal continues to be transmitted to the outer circumference of the booster network board 3, the mass block 7 can quickly pull the flying net 10 out to capture the drone affected by fragments, enabling the device to achieve the dual countermeasure effects of striking and capturing, and making the device more perfect.

[0028] Working principle: Charge the inside of the first charge slot 5 through the first charge hole 501 and the second charge hole 502 opened on the inner wall of the first charge slot 5. Through the charge port 503 opened on the surface of the first charge slot 5, the charges loaded through the first charge hole 501 and the second charge hole 502 can enter the inside of the first charge slot 5 where the first charge hole 501 and the second charge hole 502 are not opened, making the charging effect better. Charge the inside of the second charge slot 6 through the third charge hole 601 opened at the middle position of the second charge slot 6 during charging. Then, energize and excite the agents loaded inside the first charge slot 5 and the second charge slot 6 through the connecting piece 2 installed inside the bottom shell 1, enabling the charge to transfer detonation energy and opening the panel 4 installed inside the booster network board 3. Through the first prefabricated groove 401 and the second prefabricated groove 402 opened on the surface of the panel 4, high-speed fragments flying in a specific direction are formed to form damage elements with directional killing effect to counter the drone, enabling the device to achieve the strike on the drone. By evenly installing the mass blocks 7 on the outer circumference of the booster network board 3, the installation block 8 fixedly installed at the bottom of the mass block 7 is installed at one end of the connecting wire 9 through a bolt, and the other end of the connecting wire 9 is fixedly installed on the surface of the flying net 10. When the detonation signal continues to be transmitted to the outer circumference of the booster network board 3, the mass block 7 can quickly pull the flying net 10 out to capture the drone affected by fragments, enabling the device to achieve the dual countermeasure effects of striking and capturing, and making the device more perfect.
