Description

Technical Field

[0001] This utility model relates to the field of drone countermeasures technology, and in particular to a net-catching drone countermeasure device based on a drone platform. Background Technology

[0002] With the rapid development and widespread application of drone technology, drones play a vital role in civilian and military fields. However, the misuse and illegal intrusion of drones have also brought serious security risks. Various types of "black flight" drones pose a significant threat to public safety, military facilities, and privacy. "Black flight" of drones refers to the use of drones in no-fly zones without registration and approval, thereby interfering with air traffic and endangering public safety. In my country, any unauthorized flight in a protected airspace without permission from air traffic control is prohibited, and serious cases will incur corresponding legal liabilities. However, with the popularization of drone technology, black flight phenomena are commonplace, posing a significant challenge to public safety. Therefore, research into drone countermeasure technologies is needed to solve the problem of black flight drones.

[0003] Existing drone countermeasures technologies mainly include electromagnetic interference, laser strikes, and net launchers. Electromagnetic interference technology interferes with the drone's communication link by emitting radio frequency signals in the same frequency band as the drone's communication, causing it to lose control or reduce its communication quality. This technology has advantages such as low cost, good effect, and ease of implementation. However, it may accidentally damage legitimate drones and is ineffective against autonomous navigation drones. Laser strike technology uses high-energy laser beams to irradiate drones, destroying key components or structures through the thermal effect or shock wave effect of the laser. This technology has advantages such as high precision and good damage effect, but it is costly, requires highly skilled operators, and poses safety hazards. Net launchers use specially designed net objects to entangle or trap drones, rendering them unable to fly. This technology is suitable for intercepting low-altitude, slow-flying drones and is fast and effective. However, net launchers typically have a range of 30-50 meters, a slow response speed, and are difficult to deal with high-altitude or high-speed drones.

[0004] Therefore, there is an urgent need to research a low-cost, high-success-rate, safe and reliable anti-drone device to solve the problem of countering unauthorized drone flights. Utility Model Content

[0005] The purpose of this invention is to provide a drone countermeasure device that is low in cost, highly mobile, has a high success rate in interception, and is highly secure.

[0006] The technical solution to achieve the purpose of this utility model is: a net-catching drone countermeasure device based on a drone platform, including a drone platform, a pneumatic net-catching launcher, and a net-catching projectile;

[0007] The drone platform is used to install the pneumatic net launching device and net projectiles, to provide a launching platform for the pneumatic net launching device, and to transport the pneumatic net launching device and net projectiles to a location near the target drone.

[0008] The pneumatic net launching device is installed on the UAV platform and is used to launch net projectiles to capture the target UAV.

[0009] The net-catching projectile is launched by a pneumatic net-catching launcher and unfolds to form a three-dimensional interception net to intercept the target drone.

[0010] As a specific example, the drone platform includes a drone, a mounting bracket, a base plate on the mounting bracket, and an information acquisition device;

[0011] The upper base plate of the bracket is fixed to the support frame at the bottom of the UAV with screws.

[0016] As a specific example, the net is stored in a star-shaped folding manner inside the netting projectile. The edge of the net is connected to the arc-shaped projectile body, which acts as a counterweight. After launch, the net unfolds due to inertia, forming a three-dimensional interception net.

[0017] As a specific example, the pneumatic net launching device adopts a sliding rail suspension and is connected to the UAV platform through a quick-release structure, which facilitates the rapid replacement of high-pressure gas cylinders and nets.

[0032] like Figure 1As shown, this utility model discloses a net-catching drone countermeasure device based on a drone platform, including a drone platform 1, a pneumatic net-catching launcher 2, and a net-catching projectile 3.

[0033] The UAV platform 1 is used to install the pneumatic net launching device 2 and the net projectile 3, to provide a launching platform for the pneumatic net launching device 2, and to transport the pneumatic net launching device 2 and the net projectile 3 to a location near the target UAV.

[0034] The pneumatic net launching device 2 is installed on the UAV platform 1 and is used to launch net projectiles 3 to capture the target UAV.

[0035] The net-catching projectile 3 is launched by the pneumatic net-catching launcher 2 and unfolds to form a three-dimensional interception net to intercept the target drone.

[0036] As a specific example, the unmanned aerial vehicle (UAV) platform 1 includes a UAV 1-1, a mounting bracket 1-2, a base plate 1-3 on the mounting bracket, and an information acquisition device 1-4, such as... Figure 1 As shown;

[0037] The upper base plate 1-3 of the bracket is fixed to the support frame at the bottom of the UAV 1-1 with screws. The upper part of the bracket 1-2 has an I-shaped structure and is spliced ​​with the groove at the bottom of the upper base plate 1-3. The lower part of the bracket 1-2 has a groove structure for installing the pneumatic net-catching launcher 2. An information acquisition device 1-4 is set at the front end of the UAV 1-1, including a camera and an infrared sensor, for identifying the target UAV and providing information data of the target UAV for the pneumatic net-catching launcher 2 to launch the net-catching projectile 3.

[0038] As a specific example, the pneumatic net launching device 2 includes a launching chamber 2-1, a connecting ring 2-2, a solenoid valve 2-3, a gas cylinder chamber 2-4, a T-shaped workpiece 2-5, a high-pressure gas cylinder 2-6, and a high-pressure gas cylinder plug 2-7, such as... Figure 2 As shown;

[0039] The surface of the gas cylinder compartment 2-4 is provided with a T-shaped workpiece 2-5, which is spliced ​​with the groove structure at the bottom of the bracket 1-2 to install the pneumatic net-catching launcher 2 at the bottom of the UAV platform 1; the launch compartment 2-1 and the gas cylinder compartment 2-4 are connected by threads through a connecting ring 2-2, the high-pressure gas cylinder 2-6 is installed in the gas cylinder compartment 2-4, and the high-pressure gas cylinder plug 2-7 is installed at the front end of the high-pressure gas cylinder 2-6, which is connected to the solenoid valve 2-3; the net-catching projectile 3 is placed in the launch compartment 2-1, and the tail fin of the net-catching projectile 3 is fixed into the launch compartment 2-1 through the guide groove in the launch compartment 2-1 to ensure that the shape of the net-catching projectile 3 is fixed; the tail end of the net-catching projectile 3 is connected to the solenoid valve 2-3.

[0040] As a specific example, the net-catching projectile 3 includes a net 3-1, an arc-shaped projectile body 3-2, and a clamp 3-3, such as Figure 3 As shown;

[0041] Four arc-shaped projectiles 3-2 are combined to form the outer shell of the net-catching projectile 3, and the front end is fixed by a clamp 3-3; a net 3-1 is installed inside the net-catching projectile 3, which is placed in a star shape and connected to the four arc-shaped projectiles 3-2 at its four corners respectively.

[0042] As a specific example, the net 3-1 is stored in a star-shaped folding manner inside the net-catching projectile 3. The edge of the net 3-1 is connected to the arc-shaped projectile body 3-2, which acts as a counterweight. After launch, the net 3-1 unfolds due to inertia, forming a three-dimensional interception net. Figure 4 As shown.

[0043] As a specific example, the pneumatic net launching device 2 adopts a sliding rail suspension and is connected to the UAV platform 1 through a quick-release structure, which facilitates the rapid replacement of the high-pressure gas cylinder 2-6 and the net 3-1.

[0044] As a specific example, the high-pressure gas cylinders 2-6 can support 5-8 launches with a single filling.

[0045] As a specific example, the net 3-1 is recyclable and refillable.

[0046] As a specific example, the response time of the pneumatic net launching device 2 is ≤2 seconds, and the entire process from target identification to net launch is ≤2 seconds.

[0047] As a specific example, the pneumatic net launching device 2 poses no risk of explosion and complies with the specifications for low-altitude security equipment.

[0048] The method of using the net-catching drone countermeasure device based on the drone platform of this utility model is as follows: After the information acquisition device 1-4 set at the front end of the drone platform 1 identifies the target drone, the operator remotely controls the opening of the solenoid valve 2-3. The high-pressure gas in the high-pressure gas cylinder 2-6 connected to it pushes the net-catching projectile 3 at the other end out of the launch chamber 2-1 through the solenoid valve 2-3. The net-catching projectile 3 is launched towards the target drone by the thrust of the high-pressure gas. After leaving the launch chamber 2-1, the clamps 3-3 that fix the four arc-shaped projectiles 3-2 are broken by air resistance. Since the rear of the arc-shaped projectiles 3-2 is not fixed... The four arc-shaped projectiles 3-2 are completely dispersed, and the net 3-1 placed inside the net-catching projectile 3 unfolds in the air. The four arc-shaped projectiles 3-2 connected to the four corners of the net 3-1 act as counterweights, driving the net 3-1 to fully unfold in the air and fly towards the target drone in a three-dimensional net shape. After the net 3-1 contacts the target drone, the arc-shaped projectiles 3-2 continue to fly forward due to inertia, so that the net 3-1 completely covers and wraps around the target drone, making it unable to continue flying. Under the action of the gravity of the arc-shaped projectiles 3-2, it falls to the ground, thus achieving the purpose of intercepting the target drone.

[0049] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
