Description

Technical Field

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

[0002] Countermeasures against drones were developed to address the security threats posed by drones. Through detection, identification, electronic jamming, and physical interception, it effectively manages and controls drone activity, ensuring airspace security, privacy protection, and legal flight. With the increasing prevalence of drone technology, the importance of countermeasures has become increasingly prominent, making it one of the key technologies for maintaining national security and social stability.

[0003] Existing technologies for countering drones have the following drawbacks: Inappropriate power system layout: In existing UAV designs, the power system layout often suffers from insufficient symmetry, resulting in uneven thrust distribution. This can easily lead to inaccurate attitude control during high-speed flight, affecting flight stability and maneuverability.

[0004] Structural strength and lightweight design are difficult to balance: In the design of traditional drones, either lightweight design is sacrificed to ensure structural strength, increasing energy consumption; or structural strength is reduced to achieve lightweight design, leading to decreased flight safety and reliability. This balance is difficult to achieve, limiting the performance improvement of drones.

[0005] High air resistance: Most drones have a non-streamlined design, which fails to effectively reduce air resistance. This not only reduces flight speed but also increases energy consumption, affecting the drone's endurance and flight efficiency. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a countermeasure against drones.

[0007] To achieve the above objectives, this utility model provides a countermeasure drone, including a fuselage. Multiple arms are fixed to the outer side of the middle portion of the fuselage. Each arm includes a main arm fixed to the fuselage and an arm shell covering the outer side of the main arm. A rotary motor is fixed to the lower outer end of the main arm. A motor cover is provided at the outer end of the arm shell. The rotary motor is housed within the motor cover, with its lower shaft positioned outside the lower end of the motor cover. A propeller is fixed to the lower end of the rotary motor's shaft. The upper end of the motor cover is conical. A camera and a GNSS antenna are mounted on the fuselage. The rotary motor, camera, and GNSS antenna are all connected to a main control board located within the fuselage. The main control board is connected to a battery located within the fuselage.

The upper end of the motor cover 23 is conical, and the arm shell 22 is also sickle-shaped. This design effectively reduces air resistance and can increase flight speed. Preferably, several vents 24 are provided at the upper end of the motor cover 23 to allow some air to enter the motor cover 23 during operation to dissipate heat from the rotary motor 3. A camera 5 and a GNSS antenna 6 are installed on the fuselage 1. The camera can capture images and videos to achieve real-time monitoring and data acquisition. The GNSS antenna 6 receives positioning signals to ensure that the UAV can accurately locate itself.

The camera 5 can be mounted on the first mounting plate 111. An opening is provided at the corresponding position of the housing 12 and the camera 5, allowing the camera 5 to extend beyond the housing 12 through the opening, thus avoiding interference with the camera 5's shooting. The main control board and battery are preferably fixed to the upper sides of the second mounting plate 112 and the fifth mounting plate 115, respectively. It is also preferable to provide a gimbal 7 between the camera 5 and the first mounting plate 111 to adjust the shooting angle of the camera 5.
