Technical Field

[0001] This utility model relates to the field of laser interception and countermeasures against drones, specifically a laser interception and countermeasures device for drones. Background Technology

[0002] With the rapid advancement of drone technology, the explosive growth in the number of drones has also created a huge regulatory blind spot. Due to the relatively blurred lines between civilian drones and model aircraft, and the weak regulation of sales, unscrupulous individuals are able to fly them recklessly, posing a significant safety hazard.

[0003] Currently, existing drone capture and interception devices typically consist of a transmitter and a launch tube, and are mostly fixed. For example, Chinese patent application number 202323106284.6 discloses a fixed drone interception and countermeasure device. This patent relates to the field of drone interception and countermeasure device technology. Its structure includes a tripod, with the top of the tripod fixedly connected to the middle of the bottom of a support disk, and the top left side of the support disk fixedly connected to the bottom of a receiver controller. By setting a rotation mechanism, the drone interception and countermeasure device can rotate rapidly, and the rotation speed can be controlled. This allows the drone interception and countermeasure device to quickly rotate and aim at the drone for interception and countermeasure, improving the efficiency of drone interception and countermeasure. By setting an angle adjustment mechanism, the operation of the electric push rod in the angle adjustment mechanism will cause the drone interception and countermeasure device to tilt, allowing the drone interception and countermeasure device to be adjusted without manual control, improving the flexibility and practicality of the drone interception and countermeasure device.

[0004] Although the aforementioned patent allows the drone interception and countermeasures equipment to be adjusted without manual control, improving its flexibility and practicality, in actual use, the equipment needs to be moved to a designated location for deployment. Due to its heavy overall weight, the patent is inconvenient for users to move, making its use time-consuming and laborious, thus reducing its practicality to some extent.

[0005] Therefore, there is a need to provide a laser-based anti-drone device to solve this problem. Utility Model Content

Due to their heavy overall weight, it is inconvenient for users to move them, making the use of such devices time-consuming and laborious.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a laser interception drone countermeasure device, comprising a base, universal wheels fixedly connected to the four corners of the bottom of the base, an installation opening on the top of the base, an installation plate fixedly connected to the inner wall of the installation opening, an electric push rod fixedly connected to the top of the installation plate, the output end of the electric push rod penetrating the installation plate and fixedly connected to a brake plate, and the brake plate cooperating with the universal wheels, a support frame fixedly connected to the top of the base, a reduction motor fixedly connected to the bottom of the support frame, a rotating disk fixedly connected to the output end of the reduction motor penetrating the support frame, a mountain-shaped loading frame fixedly connected to the top of the rotating disk, loading openings symmetrically opened on both sides of the loading frame, a radio jammer body and a laser striker body symmetrically rotatably connected inside the two loading openings, a rotary motor fixedly connected to the top of the loading frame, and a detection radar body disposed on the top of the rotary motor.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, this utility model provides a laser interception drone countermeasure device, including a base 1. Universal wheels 2 are fixedly connected to the four corners of the bottom of the base 1. An installation opening 3 is provided at the top of the base 1. An installation plate 4 is fixedly connected to the inner wall of the installation opening 3. An electric push rod 5 is fixedly connected to the top of the installation plate 4. The output end of the electric push rod 5 passes through the installation plate 4 and is fixedly connected to a brake plate 6, which works in conjunction with the universal wheels 2. A support frame 7 is fixedly connected to the top of the base 1. A reduction motor 8 is fixedly connected to the bottom of the support frame 7. The output end of the reduction motor 8 passes through the support frame 7 and is fixedly connected to a rotating disk 9. A mountain-shaped loading rack 10 is fixedly connected to the top of the rotating disk 9. Loading openings 11 are symmetrically provided on both sides of the loading rack 10. A radio jammer body 12 and a laser striker body 13 are symmetrically rotatably connected inside the two loading openings 11. A rotary motor 14 is fixedly connected to the top of the loading rack 10. A detection radar body 15 is provided on the top of the rotary motor 14. The radio jammer body 12 and the laser striker body 13 are symmetrically rotatably connected inside the two loading openings 11. The main body 13 of the optical striker is a product of existing mature technology. The radio jammer generates interference signals with the same or similar communication frequency as the UAV, and uses the competition for electromagnetic spectrum resources to disrupt the normal communication and navigation of the UAV. The laser striker mainly uses a high-energy-density laser beam to damage the target UAV, causing it to lose its flight capability. Its core component is a laser generator, which usually uses a solid-state laser or a gas laser. The main body 12 of the radio jammer and the main body 13 of the laser striker are respectively equipped with a thermal imager and a visible light lens. The thermal imager detects the infrared radiation energy emitted by the object through its detector. The infrared radiation intensity emitted by the object is different at different temperatures. The higher the temperature, the greater the radiation intensity. The visible light lens is composed of multiple optical lenses. Its function is to collect and focus the light from the object onto the imaging element. By precisely designing the curvature, refractive index and other parameters of the lens, light from different directions can be accurately converged on the imaging element to form a clear image, thereby enabling the identification of the UAV.

[0023] refer to Figure 2 and Figure 3 Limiting openings 16 are provided at the four corners of the top of the mounting plate 4, and limiting posts 17 are fixedly connected at the four corners of the top of the brake plate 6, and the limiting posts 17 are slidably connected to the limiting openings 16.

[0024] As a technical optimization of this utility model, the setting of the limiting port 16 and the limiting post 17 plays a limiting and guiding role in the lifting and lowering of the brake plate 6, ensuring that the brake plate 6 can smoothly contact or separate from the universal wheel 2, thereby improving the reliability and stability of braking.

[0025] refer to Figure 1 and Figure 2 A battery 18 and a receiver controller 19 are symmetrically fixedly connected to the top of the base 1.

[0026] As a technical optimization of this utility model, the battery 18 provides power to the device, enabling it to work normally without an external power source, thus enhancing its independence and mobility. The receiver controller 19 can receive external commands and control the various components of the device, achieving intelligent operation and improving the device's efficiency.

[0027] refer to Figure 4 The inner wall of the loading frame 10 is symmetrically provided with adjustment slots. The two adjustment slots are fixedly connected to the deflection motors 20, and the output ends of the two deflection motors 20 are fixedly connected to the radio jammer body 12 and the laser striker body 13, respectively.

[0028] As a technical optimization of this utility model, by setting two deflection motors 20, the radio jammer body 12 and the laser striker body 13 can be deflected in the vertical direction respectively, so as to more accurately counter drones at different heights and angles and expand the coverage of the countermeasure.

[0029] refer to Figure 4 The output end of the rotary motor 14 is fixedly connected to the support plate 21, the top of the support plate 21 is fixedly connected to the bidirectional motor 22, the output end of the bidirectional motor 22 is fixedly connected to the connecting strip 23, and the top of the connecting strip 23 is fixedly connected to the detection radar body 15.

[0030] As a technical optimization of this utility model, by setting up the support plate 21, the bidirectional motor 22 and the connecting strip 23, the detection radar body 15 can rotate independently horizontally, and can also adjust its angle independently in the vertical direction, thereby more flexibly detecting UAVs in different positions and improving the accuracy and comprehensiveness of detection.

[0031] refer to Figure 3 The top of the support frame 7 is fixedly connected to a balance frame 24, and the bottom of the rotating disk 9 is fixedly connected to a balance ring 25, and the balance ring 25 is rotatably connected to the balance frame 24.

[0032] As a technical optimization of this utility model, the balance frame 24 and balance ring 25 play a balancing and stabilizing role when the rotating disk 9 rotates, reducing the vibration and shaking of the loading frame 10 and ensuring the working accuracy of components such as the radio jammer body 12, the laser striker body 13 and the detection radar body 15.

[0033] The working principle and usage process of this utility model are as follows: When using this laser-based anti-drone interception device, it is first moved by the casters 2 at the four corners of the bottom of the base 1, allowing the device to be easily transported to a designated location. When it is necessary to fix the device, the electric push rod 5 on the mounting plate 4 is activated. The output end of the electric push rod 5 pushes the brake plate 6 downward, causing the brake plate 6 to engage with the casters 2, restricting the rotation of the casters 2, thereby fixing the device in the current position. At the same time, the limiting posts 17 at the four corners of the top of the brake plate 6 slide within the limiting openings 16 at the four corners of the top of the mounting plate 4, which serves to limit and stabilize the brake plate 6. The reduction motor 8 at the bottom of the support frame 7 at the top of the base 1 is activated, driving the rotating disk 9 to rotate. The mountain-shaped loading rack 10 on top of the rotating disk 9 rotates accordingly, allowing for adjustment of its direction to better counter the drone. Simultaneously, a radio jammer body 12 and a laser striker body 13 are rotatably connected to the symmetrically opened loading ports 11 on both sides of the loading rack 10. The appropriate countermeasures (radio jammer body 12 and laser striker body 13) can be selected according to actual needs. The deflection motor 20 can adjust their angles, enabling more precise jamming or attack on the target drone. At the same time, the rotation motor 14 drives the support plate 21 to rotate, and the bidirectional motor 22 on the support plate 21, via the connecting strip 23, drives the detection radar body 15 to rotate and adjust its angle. This device enables scanning and monitoring of airspace in different directions. When operating in countermeasure mode, the detection radar 15 scans the surrounding airspace. After detecting the UAV target, it transmits the target information to the receiver controller 19. Based on the target information, the receiver controller 19 controls the radio jammer 12 or the laser striker 13 to operate. If the radio jammer 12 is activated, it will emit radio signals of a specific frequency to interfere with the communication link between the UAV and the remote controller, causing the UAV to lose control or be unable to fly normally. If the laser striker 13 is activated, it will emit a high-energy laser beam to irradiate the UAV's key components, such as sensors and batteries, causing the UAV to be damaged or crash.
