Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) device technology, and in particular relates to a UAV device with sound wave deterrence function. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are intelligent flight systems that integrate technologies from multiple disciplines and are widely used in civilian, industrial, and military fields.

[0003] A drone-based bird deterrent device (publication number: CN211407434U) disclosed in the public notice includes a drone body with a three-axis gimbal at its bottom. The gimbal is equipped with an acoustic deterrent component, a visual deterrent component, and a thermal imaging component. The acoustic deterrent component consists of an ultrasonic generator and a high-frequency speaker, while the visual deterrent component consists of an LED light and a laser generator. This invention uses a combination of sound waves, ultrasonic waves, LED lights, and high-brightness lasers to deter birds and animals, achieving good deterrent effects. Furthermore, equipped with a thermal imaging component, it can be controlled via the drone's flight control system or an independent radio control system, enabling manual or automatic deterrent actions.

[0004] The aforementioned application, through the cooperation of the acoustic repelling component and the three-axis gimbal, makes it difficult to achieve precise directional propagation and flexible control of the coverage area when using acoustic waves to drive away birds and animals. This results in the acoustic waves easily spreading indiscriminately to non-target areas, causing a significant waste of acoustic energy due to scattering, reducing the repelling intensity in the target area, and easily leading to ecological problems such as complaints about disturbing residents or accidentally driving away beneficial birds. Therefore, we propose a drone device with acoustic repelling function. Utility Model Content

[0005] The purpose of this invention is to provide a drone device with a sound wave deterrent function, which solves the problem of flexible switching of coverage range by manually turning the baffle.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a drone device with sound wave driving function, including: a landing gear, an organism fixedly connected to the side of the landing gear, a battery installation compartment opened on the inner side wall of the organism, a bracket fixedly connected to the side of the organism, a motor fixedly connected to the top of the bracket, a propeller blade rotatably connected to the top of the motor, and an adjustable baffle device provided at the bottom of the organism. The adjustable baffle device includes a mounting block, the top of which is fixedly connected to the bottom of the machine body, and an annular mounting bracket is fixedly connected to the bottom of the mounting block. A rotating shaft is rotatably connected to the bottom of the annular mounting bracket, and a plastic baffle is fixedly connected to the circumferential surface of the rotating shaft.

[0007] Furthermore, the inner wall of the plastic baffle is provided with reflective textures. These reflective textures on the inner wall of the plastic baffle can reflect and focus the sound waves emitted by the sound wave transmitter, reducing the scattering of sound waves in non-target directions and enhancing the propagation effect of the sound waves.

[0008] Furthermore, the number of plastic baffles and rotating shafts is four, and they are distributed in a circumferential array at the bottom of the annular mounting frame. With four plastic baffles and four rotating shafts, the four plastic baffles can collaboratively adjust the sound wave propagation range from different directions, while the four rotating shafts each drive one of the four plastic baffles, allowing for more flexible adjustment and adapting to the sound wave coverage requirements in different scenarios.

[0009] Furthermore, the plastic baffle is arc-shaped, and a sound wave transmitter is fixedly connected to the bottom of the annular mounting bracket. The arc-shaped plastic baffle is more likely to form a sound wave focusing channel than a planar structure, further reducing sound wave leakage and enhancing the directional propagation effect. The sound wave transmitter, as the sound wave source, is installed in a position corresponding to the plastic baffle, ensuring that the sound wave can directly achieve directional propagation through the adjustment of the plastic baffle.

[0010] Furthermore, the top of the sound wave transmitter is provided with a sound wave amplification device, which includes a connecting rod. One end of the connecting rod is fixedly connected to the bottom of the annular mounting bracket, and the other end of the connecting rod is fixedly connected to a reflector plate. The top of the reflector plate is provided with micro-honeycomb holes.

[0011] Furthermore, the number of micro-honeycomb holes is set to several, and they are arranged in a circumferential array on the top of the reflector. The several micro-honeycomb holes can uniformly constrain the sound waves in different areas of the reflector. The distribution of the circumferential array is adapted to the circumferential distribution of the annular mounting bracket and the plastic baffle, ensuring that the sound waves can still maintain uniform propagation in the circumferential direction after reflection.

[0012] Furthermore, the reflector is arc-shaped. The curved surface of the arc-shaped reflector can better fit the propagation path of the sound wave, increasing the reflection area of ​​the sound wave. Compared with a flat reflector, it can more fully reflect the sound waves emitted by the sound wave transmitter.

[0013] This utility model has the following beneficial effects: 1. The adjustable baffle device of this utility model can flexibly switch the coverage area by manually turning it. Combined with the sound wave recovery of the arc-shaped reflector and the directional constraint of the micro honeycomb holes in the sound wave enhancement device, it can not only make the sound waves act precisely on the target area, but also prevent the sound waves from drifting to the surrounding residential areas or bee farms. It is suitable for environmental protection and shooing needs in many scenarios such as farmland, airports, and the surrounding areas of residential communities.

[0014] 2. The micro-honeycomb holes on the top of the reflector in the sound wave enhancement device of this utility model can further constrain the reflected sound waves, reduce sound wave diffusion, and form a double-converging effect in combination with the plastic baffle, significantly improving the directionality and intensity of the sound waves and extending the effective driving distance of the sound waves.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5This utility model is a drone device with sound wave driving function, including: a landing gear 1, an organism 2 fixedly connected to the side of the landing gear 1, a battery installation compartment 3 opened on the inner side wall of the organism 2, a bracket 4 fixedly connected to the side of the organism 2, a motor 5 fixedly connected to the top of the bracket 4, a propeller blade 6 rotatably connected to the top of the motor 5, and an adjustable baffle device 7 provided at the bottom of the organism 2. The adjustable baffle device 7 includes a mounting block 701, the top of which is fixedly connected to the bottom of the body 2, and an annular mounting bracket 702 is fixedly connected to the bottom of the mounting block 701. A rotating shaft 703 is rotatably connected to the bottom of the annular mounting bracket 702, and a plastic baffle 704 is fixedly connected to the circumferential surface of the rotating shaft 703.

[0021] As shown in the figure, the inner wall of the plastic baffle 704 has reflective textures 705. The reflective textures 705 on the inner wall of the plastic baffle 704 can reflect and concentrate the sound waves emitted by the sound wave transmitter 9, reduce the scattering of the sound waves in non-target directions, and enhance the propagation effect of the sound waves.

[0022] As shown in the figure, there are four plastic baffles 704 and four rotating shafts 703, which are arranged in a circumferential array at the bottom of the annular mounting bracket 702. The four plastic baffles 704 can collaboratively adjust the sound wave propagation range from different directions, while the four rotating shafts 703 drive the four plastic baffles 704 respectively, allowing for more flexible adjustment and adapting to the sound wave coverage requirements in different scenarios.

[0023] As shown in the figure, the plastic baffle 704 is arc-shaped, and the bottom of the annular mounting bracket 702 is fixedly connected to the sound wave transmitter 9. The arc-shaped structure of the plastic baffle 704 makes it easier to form a sound wave focusing channel compared to a planar structure, further reducing sound wave leakage and enhancing the directional propagation effect. The sound wave transmitter 9, as the sound wave source, is installed in a position corresponding to the plastic baffle 704, ensuring that the sound wave can propagate directly through the adjustment of the plastic baffle 704.

[0024] As shown in the figure, the top of the sound wave transmitter 9 is provided with a sound wave amplification device 8. The sound wave amplification device 8 includes a connecting rod 801. One end of the connecting rod 801 is fixedly connected to the bottom of the annular mounting bracket 702, and the other end of the connecting rod 801 is fixedly connected to a reflector plate 802. The top of the reflector plate 802 is provided with micro honeycomb holes 803.

[0025] As shown in the figure, the number of micro-honeycomb holes 803 is set to several, and they are arranged in a circumferential array on the top of the reflector 802. The number of micro-honeycomb holes 803 can uniformly constrain the sound waves in different areas of the reflector 802. The circumferential array distribution is adapted to the circumferential distribution of the annular mounting bracket 702 and the plastic baffle 704, ensuring that the sound waves can still maintain uniform propagation in the circumferential direction after reflection.

[0026] As shown in the figure, the reflector 802 is arc-shaped. The curved surface of the reflector 802 can better fit the propagation path of the sound wave, increasing the reflection area of ​​the sound wave. Compared with the flat reflector 802, it can more fully reflect the sound waves emitted by the sound wave transmitter 9.

[0027] One specific application of this embodiment is as follows: When the device is started, the four small arc-shaped baffles are in a semi-open position by default, connected to the ring mounting bracket 702 via the pivot 703. The overall design is lightweight and does not add extra weight to the drone. At this time, the curvature of the baffles naturally conforms to the sound wave propagation path, and the plastic material has minimal impact on sound wave penetration, ensuring that the sound waves can propagate outward normally through the baffles. When it is necessary to adjust the sound wave coverage area, no parts need to be disassembled; simply turn the adjustment knob on the edge of the baffle by hand. If it is necessary to narrow the range, turn the knob clockwise, and the four plastic baffles 704 will simultaneously close towards the center, reducing the opening angle. At this time, the sound wave channel formed by the baffles is narrowed, and the sound waves are constrained, only covering the target area to drive away birds, such as a flock of birds in the middle of a farmland. If it is necessary to expand the range... When the knob is turned counterclockwise, the baffle opens outward, increasing the opening angle and widening the sound wave channel, thus expanding the sound wave coverage to cover a larger target area. After the sound wave transmitter 9 is activated, the curved structure of the plastic baffle 704 guides and concentrates the sound waves. When the baffle is closed, the inner side of the curved surface converges the sound waves towards the center, reducing scattering to both sides. When the baffle is open, the curved surface guides the sound waves to diffuse at a wider angle, but still limits excessive dispersion through the curvature. At the same time, the low barrier properties of the plastic material ensure that the sound wave energy is not lost.

[0028] One end of the connecting rod 801 is rigidly connected to the bottom of the annular mounting bracket 702, and the other end is vertically fixed to the reflector 802, ensuring that the reflector 802 is directly above the sound wave transmitter 9, with the curved surface of the reflector 802 facing downwards. The micro-honeycomb holes 803 on the top of the reflector 802 remain naturally open, without obstruction or deformation. The overall device is lightweight, does not add extra weight to the drone, and does not affect the manual adjustment of the adjustable baffle device 7. The sound waves emitted by the sound wave transmitter 9 will spread in four directions: up, down, left, and right. The upward-spreading sound waves will directly hit the curved surface of the reflector 802. Because the reflector 802 is curved and the curved surface faces the sound wave transmitter 9, the sound waves will be reflected by the mirror to the target area below, rather than drifting into the high altitude. At the same time, the curved surface can gather the dispersed upward sound waves into a beam, avoiding single beams. After a sound wave is reflected and diffuses again, it is equivalent to redirecting the previously wasted energy back to the target, increasing the overall intensity of the sound wave. The sound wave reflected by the reflector 802 may still diverge slightly during its downward propagation. At this time, the micro honeycomb holes 803 on the top of the reflector 802 will play a role: each micro honeycomb hole 803 is equivalent to a small sound waveguide, which can confine the sound wave within the channel, forcing the sound wave to propagate vertically downward and not deviate to the sides. Several honeycomb holes are arranged in a circular array along the top circumference of the reflector 802, which can uniformly constrain the reflected sound wave, ensuring that the sound wave in different areas can maintain directional propagation. In conjunction with the adjustable baffle device 7 below, a double redirection effect is formed. The direction is constrained by the honeycomb holes above, and the range is adjusted by the baffle below, allowing the sound wave to accurately cover the target area and not drift towards residential areas or bee farms.
