Description

Technical Field

[0001] This utility model relates to the field of bird deterrence equipment technology, and in particular to a bird deterrence drone. Background Technology

[0002] With the improvement of the environment and the increase in human awareness of bird protection, the types and numbers of birds are increasing day by day, leading to an increasing number of problems such as food problems caused by birds eating and destroying crops in farmland, and aviation safety problems caused by birds hitting aircraft.

[0003] To reduce the food problem caused by birds, various bird-repelling methods are commonly used. Classic methods include sound repelling and visual repelling. Common methods include: Manual bird repelling: Birds are most harmful in the early morning, midday, and evening. Arrive in the fields early and drive the birds away promptly. Check and drive them away again after 15 minutes, generally 3-5 times per period. This method is time-consuming and labor-intensive. Sound bird repelling: Record sounds such as knocking, firecrackers, hawk calls, and bird cries, and play them loudly in the fields at irregular intervals to repel birds. Sound devices should be placed around crops and at bird entry points to amplify the sound using wind direction and echoes. However, this will have a significant noise impact on nearby residents. Object bird repelling: Place mannequins, hawks, etc., in the fields. This prevents harmful birds from entering in the short term, but becomes ineffective in the long run.

[0004] Regarding aviation safety issues caused by birds, since bird strikes are defined by the International Civil Aviation Organization as one of the major hazards of Class A air accidents, airports have adopted various bird control measures to protect aviation safety and safeguard the property and lives of passengers. These measures include scarecrows, inflatable figures, automatic laser bird deterrents, bird-scaring falcons, bird-scaring vehicles, and bird-detecting radar. However, these solutions have drawbacks such as being easily limited by time and airspace and having poor bird control effects.

[0005] While some technologies have been developed to use mobile bird deterrence devices, such as those mimicking bird predators mounted on drones, in response to the fixed bird deterrence methods used to address food and aviation safety issues, these devices are often large, such as those mimicking eagles. Such large devices are easily affected by wind speeds and natural winds during flight, leading to severe ascents and descents, yaws, or even crashes, resulting in low reliability. Furthermore, they target only a limited range of bird species, thus failing to achieve the desired bird deterrence effect.

[0006] Therefore, there is an urgent need to provide a bird-repelling drone with high reliability and excellent bird-repelling effect. Utility Model Content

The base plate abuts against the bottom housing. The pair of elastic clamps are clamped to the outside of the pair of side housings. The fixing clamp is located above the top housing to connect the pair of elastic clamps. The fixing plate has a second fixing hole. The first fixing hole and the second fixing hole are connected and fixed by a fixing member.

[0009] Furthermore, the bottom shell is provided with a first positioning protrusion and a second positioning protrusion, and the bottom plate is provided with a first positioning hole and a second positioning hole. The first positioning protrusion and the second positioning protrusion are respectively positioned opposite to the first positioning hole and the second positioning hole, thereby positioning the bottom plate in a fixed position on the bottom shell. Each of the pair of side shells is provided with a third positioning protrusion, and each of the pair of elastic clamps is provided with a third positioning hole. The third positioning protrusion is respectively positioned opposite to the third positioning hole, thereby positioning the elastic clamp on a fixed position on the side shell.

[0010] Furthermore, multiple pairs of opposing reinforcing plates are provided on a pair of elastic clamps. Each reinforcing plate on each elastic clamp is arranged perpendicularly to the fixed plate. The first end of the reinforcing plate is connected to the fixed plate and extends from the first end to the second end in a direction perpendicular to the fixed plate.

[0011] Furthermore, both the base plate and the elastic clamping plate are designed as outwardly protruding arcs, the outer side of the reinforcing plate facing away from the elastic clamping plate is designed as a rounded surface, and the reinforcing plate gradually tapers from the second end relative to the first end.

[0012] Furthermore, multiple pairs of opposite openings are provided on a pair of elastic clamps. The extension lines of the vertical center lines of each opening on the elastic clamps are perpendicular to the intersection lines of the fixing plates on the elastic clamps. The openings are designed as waist-shaped holes, and a reinforcing plate is arranged between two adjacent openings.

[0013] Furthermore, a fixing groove is provided at the position of each of the pair of elastic clamps near their respective free ends, and a fixing clip passes through each fixing groove and applies a clamping force that approaches each other to the two fixing grooves. The fixing clip is a Velcro strap.

[0014] Furthermore, the flight drive includes a pair of first propellers and a pair of second propellers, both connected to the side shell of the aircraft. The two first propellers are on the same first horizontal plane, and the two second propellers are on the same second horizontal plane. In the horizontal flight direction of the bird-repelling drone, the first propellers are in front of the second propellers, and in the direction of gravity, the first horizontal plane is below the second horizontal plane.

[0015] Furthermore, a rechargeable battery is fixed in each cavity of the two sound-generating devices, and the two rechargeable batteries are arranged obliquely symmetrically with respect to the vertical symmetry plane of the casing.

[0016] Furthermore, one of the sound-emitting devices is used to emit ultrasonic waves, and the other sound-emitting device is used to emit speech. The frequency range of the ultrasonic waves is set to 12kHz-50kHz, and the sound pressure level of the speech is set to 90dB-120dB / meter.

[0028] refer to Figures 1 to 5 As an objective of this invention, a bird-repelling drone is provided, comprising a casing 1, a pair of sound-generating devices 3, and a fixing assembly 4. The casing 1 is equipped with a flight drive component 2; at least one of the sound-generating devices 3 operates to produce a bird-repelling sound. The fixing assembly 4 symmetrically fixes the pair of sound-generating devices 3 to both sides of the casing 1. Therefore, the bird-repelling drone provided by this invention, by incorporating the sound-generating devices 3 and fixing them to both sides of the casing 1 using the fixing assembly 4, not only has a small size for the sound-generating devices 3, making them less susceptible to the effects of flight wind speed and natural wind speed, thus preventing violent ascent and descent, yawing, or even crashes during flight, ensuring high reliability, but also allows the sound-generating devices 3 to flexibly utilize pre-stored sound information for different bird species, making it suitable for repelling various types of birds and resulting in excellent bird-repelling effects.

[0029] Please refer to the reference. Figures 2 to 4Specifically, the housing 1 includes a connected bottom housing 11, a top housing 12, and a pair of side housings 13. The two side housings 13 are opposite to each other and respectively connected between the bottom housing 11 and the top housing 12. The sound-generating device 3 includes a first housing 31 and a second housing 32 that are fixed to each other to form a cavity. The first housing 31 is provided with a first fixing hole 311, and the second housing 32 is provided with a sound-transmitting hole 321. The fixing assembly 4 includes a fixing frame 41 and a fixing clamp 42. The fixing frame 41 includes a base plate 411, a pair of fixing plates 412, and a pair of spaced-apart elastic clamps 4. 13. A pair of elastic clamping plates 413 extend from both sides of the fixed plate 412 away from the fixed plate 412. A fixed plate 412 on each of the elastic clamping plates 413 extends away from each other. The bottom plate 411 abuts against the bottom shell 11. The pair of elastic clamping plates 413 are clamped onto the outer sides of the pair of side shells 13. A fixing clip 42 connects the pair of elastic clamping plates 413 above the top shell 12. The fixed plate 412 has a second fixing hole 4121. The first fixing hole 311 and the second fixing hole 4121 are connected and fixed by a fastener. In this way, the fixing assembly 4 can reliably and securely fix the pair of sound-generating devices 3 to both sides of the side shell 13, ensuring high reliability of the bird-repelling drone.

[0030] Please refer to the reference. Figure 3 and Figure 5 Preferably, the bottom shell 11 is provided with a first positioning protrusion 111 and a second positioning protrusion 112, and the base plate 411 is provided with a first positioning hole 4111 and a second positioning hole 4112. The first positioning protrusion 111 and the second positioning protrusion 112 are respectively positioned opposite to the first positioning hole 4111 and the second positioning hole 4112, thereby positioning the fixed position of the base plate 411 on the bottom shell 11. Each of the pair of side shells 13 is provided with a third positioning protrusion 131, and each of the pair of elastic clamps 413 is provided with a third positioning hole 4131. The third positioning protrusion 131 is respectively positioned opposite to the third positioning hole 4131, thereby positioning the fixed position of the elastic clamp 413 on the side shell 13. In this way, the fixing frame 41 can be well positioned on all four shell parts of the shell 1, thereby ensuring that the pair of sound-generating devices 3 are symmetrically fixed on both sides of the shell 1, which not only ensures the flight balance of the bird-repelling drone, but also ensures good propagation symmetry when the two sound-generating devices 3 emit sound at the same time.

[0031] Please refer to reference 2 and... Figure 5Preferably, multiple pairs of opposing reinforcing plates 4132 are provided on a pair of elastic clamping plates 413. Each reinforcing plate 4132 on each elastic clamping plate 413 is arranged perpendicularly to the fixing plate 412. The first end of the reinforcing plate 4132 is connected to the fixing plate 412 and extends from the first end to the second end in a direction perpendicular to the fixing plate 412. Therefore, by symmetrically arranging multiple pairs of reinforcing plates 4132, the elastic clamping plates 413 have high structural strength and sufficient elastic restoring force, thereby ensuring that the elastic clamping plates 413 apply a sufficiently large elastic force to the side shell 13 to clamp the side shell 13, thereby ensuring that the pair of sound-generating devices 3 are reliably fixed in a well-positioned manner.

[0032] Please refer to the reference. Figure 5 Preferably, both the base plate 411 and the elastic clamping plate 413 are designed as outwardly protruding arcs, and the outer side of the reinforcing plate 4132 facing away from the elastic clamping plate 413 is designed as a rounded surface. The reinforcing plate 4132 gradually tapers from the second end relative to the first end. Therefore, the base plate 411 and the elastic clamping plate 413 with outwardly protruding arcs can better elastically abut against the bottom shell 11 and the side shell 13, respectively. The tapered reinforcing plate 4132 can enhance the fixed connection between the fixed plate 412 and the elastic clamping plate 413 and reduce wind resistance.

[0033] Please refer to the reference. Figure 5 Preferably, a plurality of pairs of opposing openings 4133 are provided on a pair of elastic clamping plates 413. The extension lines of the vertical center lines of each opening 4133 on the elastic clamping plate 413 intersect perpendicularly with the intersection lines of the fixing plate 412 on the elastic clamping plate 413. That is, the openings 4133 on each elastic clamping plate 413 are arranged parallel to each other in the horizontal direction. The openings 4133 are designed as oblong openings, and a reinforcing plate 4132 is arranged between two adjacent openings 4133. In this way, the oblong openings 4133 can increase the elastic restoring force of the elastic clamping plate 413 and reduce stress concentration, further enhancing the clamping effect of the elastic clamping plate 413 on the machine side shell 13.

[0034] Please refer to the reference. Figure 2 and Figure 5 Specifically, a fixing groove 4134 is provided at each of the pairs of elastic clamps 413 near their respective free ends. A fixing clip 42 passes through each fixing groove 4134 and applies a clamping force to the two fixing grooves 4134 in a mutually close manner. The fixing clip 42 is a Velcro strap. In this way, the Velcro strap is convenient to pass through each fixing groove 4134 and easy to apply and maintain the desired clamping force.

[0035] Please refer to the reference. Figure 1Specifically, the flight drive unit 2 includes a pair of first propellers 21 and a pair of second propellers 22, both connected to the side shell 13. The two first propellers 21 are on the same first horizontal plane, and the two second propellers 22 are on the same second horizontal plane. In the horizontal flight direction of the bird-repelling drone, the first propellers 21 are in front of the second propellers 22, and in the direction of gravity, the first horizontal plane is below the second horizontal plane. By setting the two pairs of propellers in this way, the bird-repelling drone has excellent flight stability and accuracy during ascent, descent, and forward flight, which is beneficial for applications in scenarios where precise tracking is used to continuously scare away birds.

[0036] Please refer to the reference. Figure 4 Preferably, each of the two sound-generating devices 3 has a rechargeable battery 33, such as a lithium battery, fixed in its respective cavity. The two rechargeable batteries 33 are arranged to be obliquely symmetrical with respect to the vertical symmetry plane of the housing 1. Since the rechargeable batteries 33 have a large weight, by being arranged in an obliquely symmetrical form, when birds are chased and accidentally collide with the bird-repelling drone, they can generate a certain anti-deflection force for the bird-repelling drone caused by the impact, which makes it easier for the bird-repelling drone to quickly regain its balance.

[0037] Please refer to the reference. Figure 1 and Figure 4 Specifically, one sound-emitting device 3 emits ultrasonic waves, and the other emits voice. The voice content is customizable and can be pre-recorded or real-time collected sounds such as bird predator calls, alarms, gunshots, and explosions, thereby startling birds. The ultrasonic frequency range is set to 12kHz-50kHz, and the voice sound pressure level is set to 90dB-120dB / meter. The ultrasonic bird-repelling mode and the voice bird-repelling mode can be switched as needed, or both modes can be activated simultaneously to achieve the best bird-repelling effect. It is known that the bird-repelling drone has a controller, and the controller, sound-emitting device 3, and flight drive 2 are all electrically connected to the rechargeable battery 33. The controller can receive control commands from a central control unit or a mobile app to control the flight drive 2 and sound-emitting device 3, thereby emitting targeted bird-repelling sounds along a predetermined flight path for different bird species.
