Description

Technical Field

[0001] This invention relates to a method for identifying and dispersing wild animals, belonging to the field of forestry technology. Background Technology

[0002] Wild animals refer to animals that live in their natural environment and have not been domesticated. The term "wild animals" can be broadly or narrowly defined. Broadly, it includes mammals, birds, reptiles, amphibians, fish, mollusks, and insects. Narrowly, it refers to all of the above-mentioned animals except fish and invertebrates, including mammals, birds, reptiles, and amphibians. Based on the degree of their relationship with humans, wild animals can also be divided into wild animals in their natural habitat and captive-bred wild animals.

[0003] In the forestry sector, wildlife migration is usually taken into consideration, and protective measures for key facilities in the field (including dispersing gathered wildlife) are typically taken into account. Dispersing wildlife is not only beneficial to improving the security of key facilities, but also poses a significant safety hazard, especially for wildlife near railways and other areas where gatherings can create serious problems.

[0004] In the field of dispersal, directional acoustic dispersants are commonly used for dispersing people. However, these devices primarily utilize sound waves that are harmful to the human auditory organs, causing the corresponding organs to resonate and shift or deform, resulting in severe discomfort such as dizziness, nausea, and vomiting, thereby achieving the purpose of dispersal. However, our company's research has found that because human auditory organs differ from those of animals, current directional acoustic dispersants are not very effective at dispersing animals and require further improvement.

[0005] In addition, how to accurately identify wild animals in order to precisely disperse them is also a challenge.

[0006] Based on this, the present invention is proposed. Summary of the Invention

[0007] This invention addresses the shortcomings of existing technologies by providing a method for identifying and dispersing wild animals. The specific technical solution is as follows:

[0008] A method for identifying and dispersing wild animals includes the following steps:

[0009] Step S1: Obtain original video data by capturing videos of wild animals through a camera; use an image recognition and classification module to identify, classify, and record wild animals in the original video data to obtain classification data; use a motion capture module to capture motion of the classification data to generate motion model data; perform deep learning on the motion model data and write unique label parameters for the wild animal based on its behavioral knowledge; integrate the label parameters to build a unique action behavior label database for each wild animal.

[0010] Step S2: Capture passing animals with a camera to obtain real-time video data. Classify the animals in the real-time video data using an image classification module to obtain unknown species data. Use a motion capture module to capture the unknown species data to generate action tag data to be identified. Use an image comparison module to compare the action tag data to be identified with the action behavior tag data in the action behavior tag database. When the comparison result is greater than or equal to the threshold, the passing animal is determined to be a wild animal.

[0011] Step S3: When a passing animal is identified as a wild animal, the image tracking and counting module tracks and counts the number of wild animals within the camera's field of view, and calculates the density of wild animals within the camera's field of view.

[0012] Step S4: When the density of wild animals is greater than or equal to the set value, activate the wild animal sonic deterrent device to disperse the wild animals.

[0013] Step S5: The density of wild animals within the camera's field of view is recalculated using the image tracking and counting module. When the density of wild animals is less than the set value, the wild animal sonic disperser is turned off.

[0014] Further optimization of the above technical solution: the wildlife acoustic deterrent includes an acoustic deterrent body, a first vertical plate fixedly installed at the lower part of the acoustic deterrent body, an inclined metal plate, a second vertical plate, a protrusion fixedly installed on the outside of the metal plate, and a high-frequency striking drive mechanism for striking the protrusion at high frequency. The upper end of the metal plate is fixedly connected to the lower end of the first vertical plate, and the upper end of the second vertical plate is fixedly connected to the lower end of the metal plate. The protrusion has a semi-ellipsoidal structure and is located between the upper end of the metal plate and the middle part of the metal plate.

[0015] The high-frequency striking drive mechanism includes an outer casing, a turntable, a connecting shaft coaxially connected to the turntable, a motor, a reducer, and striking components. The end of the connecting shaft is rotatably connected to the outer casing via a bearing. The turntable, motor, and reducer are all located inside the outer casing. The motor drives the connecting shaft to rotate through the reducer. An annular groove is provided on the outer side of the turntable. The annular groove includes an arc groove segment with a superior arc structure. A V-shaped groove segment is provided at the arc opening of the arc groove segment. The V-shaped groove segment includes two inclined grooves with an obtuse angle between them. A smooth first transition segment connects the end of the inclined groove to the arc groove segment, and a smooth second transition segment connects the beginnings of the two inclined grooves. The striking assembly includes a spherical slider with a clearance fit to the annular groove, a first connecting rod integrally connected to the spherical slider, a first connecting plate perpendicularly connected to the first connecting rod, an optical shaft, a sleeve sleeved outside the optical shaft, a second connecting plate, a U-shaped connecting seat, and a metal ball for striking the protrusion. A circular shaft passes through the metal ball, and the metal ball is rotatably connected to the circular shaft. The circular shaft is fixedly connected to the end of the U-shaped connecting seat. The first end of the second connecting plate is fixedly connected to the end of the U-shaped connecting seat. One end of the sleeve is fixedly connected to the tail end of the second connecting plate, and the other end of the sleeve is fixedly connected to the first connecting plate. The sleeve is rotatably connected to the optical shaft, and the optical shaft is fixedly connected to the outer casing. The axial direction of the first connecting plate is perpendicular to the axial direction of the sleeve.

[0016] In a further optimization of the above technical solution, the wildlife acoustic deterrent also includes a limiting mechanism for limiting the movement trajectory of the upper end of the metal plate. The limiting mechanism includes a side plate, and a rotating shaft is connected between the upper end of the metal plate and the lower end of the first vertical plate. The rotating shaft is rotatably connected to the connection between the upper end of the metal plate and the lower end of the first vertical plate. The outer side of the side plate is provided with an arc-shaped groove that matches the rotating shaft. The arc-shaped groove has an arc-shaped structure.

[0017] In a further optimization of the above technical solution, the distance between the protrusion and the upper end of the metal plate is a, and the distance between the protrusion and the lower end of the metal plate is b, where 0.15≤a / (a+b)≤0.35.

[0018] Further optimization of the above technical solution results in an included angle of 155°~158° between the two inclined sections.

[0019] In a further optimization of the above technical solution, a side hole is provided on one side of the outer box for the second connecting plate to move, and a sealing bag is used to cover and seal the side hole; the metal ball and the U-shaped connecting seat are both located on the outside of the outer box; a support rod is fixedly connected to the lower part of the outer box, and a third connecting plate is fixedly installed between the side plate and the outer box.

[0020] In a further optimization of the above technical solution, the angle between the metal plate and the horizontal plane is λ, where 15°≤λ≤45°.

[0021] In a further optimization of the above technical solution, a water tank is installed on the outside of the acoustic wave diffuser body, and a solenoid valve is installed at the bottom of the water tank. The input end of the solenoid valve is connected to the inner cavity of the water tank; an electronic level gauge is installed inside the water tank.

[0022] A further optimization of the above technical solution is that, when the wild animal is a bird, the sound wave signal input to the input module inside the sound wave disperser body is a triangular wave signal.

[0023] When the wild animal is a large mammal, the sound wave signal input to the input module in the body of the sound wave disperser is a composite wave signal of bell wave and sine wave. Large mammals refer to mammals with a body length of more than 75cm or a body height of more than 75cm.

[0024] When the wild animal is a small mammal, the sound wave signal input to the input module in the body of the sound wave disperser is a composite wave signal of sharp pulse wave and sine wave. Small mammals refer to mammals with a body length of less than 75cm and a body height of less than 75cm.

[0025] Further optimization of the above technical solution: when the wild animal is a bird, the body of the acoustic wave disperser vibrates at a high frequency of 26~31Hz.

[0026] When the wild animal is a large mammal, the acoustic diffuser body vibrates at a high frequency of 33~35Hz.

[0027] When the wild animal is a small mammal, the body of the acoustic diffuser vibrates at a high frequency of 41-43 Hz.

[0028] The beneficial effects of this invention are:

[0029] The described wildlife identification and dispersal method can accurately identify wild animals, and then accurately disperse them using a specially designed wildlife sonic dispersal device. The dispersal effect is good, the application value is high, and it is worth promoting. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Example

[0040] A method for identifying and dispersing wild animals includes the following steps:

[0041] Step S1: Obtain original video data by capturing videos of wild animals through a camera. Use an image recognition and classification module to identify, classify, and record the wild animals in the original video data to obtain classification data. Use a motion capture module to capture motion data from the classification data to generate motion model data. Perform deep learning on the motion model data and write unique label parameters for each wild animal based on its behavioral knowledge. Integrate the label parameters to build a unique action behavior label database for each wild animal, which will facilitate accurate identification in the future.

[0042] Step S2: Real-time video data is obtained by filming passing animals with a camera. The animals in the real-time video data are classified by the image classification module to obtain unknown species data. The motion capture module captures the motion of the unknown species data to generate action tag data to be identified. The action tag data to be identified is compared with the action behavior tag data in the action behavior tag database by the image comparison module. When the comparison result is greater than or equal to the threshold, the passing animal is determined to be a wild animal. The main purpose is to accurately identify wild animals and distinguish between ordinary animals and wild animals.

[0043] Step S3: When a passing animal is identified as a wild animal, the image tracking and counting module tracks and counts the number of wild animals within the camera's field of view, and calculates the density of wild animals within the camera's field of view. This is to facilitate subsequent determination of whether wild animals are gathering, because only when there is a large-scale gathering phenomenon is it necessary to disperse them, and in other cases, it is generally not necessary to disperse them.

[0044] Step S4: When the density of wild animals is greater than or equal to the set value, activate the wild animal sonic disperser to disperse the wild animals.

[0045] Step S5: The density of wild animals within the camera's field of view is recalculated using the image tracking and counting module. When the density of wild animals is less than the set value, the wild animal sonic disperser is turned off.

[0046] Wildlife sonic deterrents can accurately disperse wild animals, thus effectively preventing large-scale gatherings of wild animals. Example

[0047] like Figures 1-5 As shown, the wildlife acoustic deterrent includes an acoustic deterrent body 10, a first vertical plate 11 fixedly installed at the lower part of the acoustic deterrent body 10, an inclined metal plate 12, a second vertical plate 13, a protrusion 14 fixedly installed on the outside of the metal plate 12, and a high-frequency striking drive mechanism 30 for striking the protrusion 14 at high frequency. The upper end of the metal plate 12 is fixedly connected to the lower end of the first vertical plate 11, and the upper end of the second vertical plate 13 is fixedly connected to the lower end of the metal plate 12. The protrusion 14 has a semi-ellipsoidal structure and is located between the upper end of the metal plate 12 and the middle part of the metal plate 12.

[0048] The high-frequency striking drive mechanism 30 includes an outer casing 31, a turntable 33, a connecting shaft 331 coaxially connected to the turntable 33, a motor 312, a reducer 310, and a striking assembly. The end of the connecting shaft 331 is rotatably connected to the outer casing 31 via a mounting bearing 311. The turntable 33, motor 312, and reducer 310 are all located inside the outer casing 31. The motor 312 drives the connecting shaft 331 to rotate through the reducer 310. A ring is provided on the outer side of the turntable 33. The annular groove includes an arc groove segment 332, which has a superior arc structure. A V-shaped groove segment 333 is provided at the arc opening of the arc groove segment 332. The V-shaped groove segment 333 includes two inclined grooves 3331, with an obtuse angle between them. The ends of the inclined grooves 3331 and the arc groove segment 332 are connected by a smooth first transition section 3333, and the beginnings of the two inclined grooves 3331 are connected by a smooth second transition section. 3332 transition; the striking assembly includes a spherical slider 37 with a clearance fit to the annular groove, a first connecting rod 371 integrally connected to the spherical slider 37, a first connecting plate 34 perpendicularly connected to the first connecting rod 371, an optical axis 361, a sleeve 36 sleeved outside the optical axis 361, a second connecting plate 39, a U-shaped connecting seat 38, and a metal ball 35 for striking the protrusion 14. A circular shaft 351 passes through the metal ball 35, and the metal ball 35 rotates with the circular shaft 351. The circular shaft 351 is fixedly connected to the port of the U-shaped connecting seat 38, the first end of the second connecting plate 39 is fixedly connected to the end of the U-shaped connecting seat 38, one end of the sleeve 36 is fixedly connected to the tail end of the second connecting plate 39, the other end of the sleeve 36 is fixedly connected to the first connecting plate 34, the sleeve 36 is rotatably connected to the optical axis 361, the optical axis 361 is fixedly connected to the outer box 31, and the axial direction of the first connecting plate 34 is perpendicular to the axial direction of the sleeve 36.

[0049] In this embodiment, the semi-ellipsoidal structure is half of an ellipsoid, which is cut along the major axis of the ellipse; the arc opening is the opening of the arc-shaped structure.

[0050] First, when the inclined metal plate 12 strikes the protrusion 14 at high frequency, it causes the acoustic wave disperser body 10 above it to vibrate at high frequency. The angle between the metal plate 12 and the horizontal plane is λ, where 15°≤λ≤45°. Preferably, during vibration, 39°≤λ≤41°, thus ensuring that the beam angle deviation of the acoustic wave disperser body 10 during vibration does not exceed 1.3°. If λ is too small, the metal plate 12 must be too long, resulting in an excessively large offset amplitude from the vibration, and the final beam angle deviation is likely to exceed 5°. If λ is too large, the closer the metal plate 12 is to being vertical, the worse the beam superposition effect becomes, which is also detrimental to improving the dispersing effect.

[0051] Secondly, the distance between the protrusion 14 and the upper end of the metal plate 12 is 'a', and the distance between the protrusion 14 and the lower end of the metal plate 12 is 'b', where 0.15 ≤ a / (a+b) ≤ 0.35. The smaller 'a' is, the greater the vibration amplitude of the acoustic wave disperser body 10 at the same striking frequency of the high-frequency striking drive mechanism 30, and the easier it is for the beam angle deviation to exceed 5°. The larger 'a' is, the worse the beam superposition effect is at the same striking frequency of the high-frequency striking drive mechanism 30, which is also detrimental to improving the dispersing effect. Therefore, most preferably, a / (a+b) = 0.21.

[0052] If the protrusion 14 is a spherical structure, the metal ball 35, due to the limitation of its movement trajectory, will easily wear down after a single impact on the protrusion 14 over a long period of time. Tests have shown that after a cumulative 1000 impacts, the spherical protrusion 14 is prone to wear, causing the vibration frequency of the acoustic wave diffuser body 10 to fall below 26Hz, necessitating replacement. However, the protrusion 14 of this invention, with a semi-ellipsoidal structure, does not easily wear down even after a cumulative 3300 impacts, and the vibration frequency of the corresponding acoustic wave diffuser body 10 can still reach 26Hz.

[0053] The specific process of the high-frequency striking drive mechanism 30 is as follows:

[0054] Motor 312 drives connecting shaft 331 and turntable 33 to rotate via reducer 310. The annular groove on the side of turntable 33 rotates continuously, causing spherical slider 37 to move along the trajectory of the annular groove. Spherical slider 37 drives sleeve 36 to rotate along optical axis 361 via first connecting rod 371 and first connecting plate 34, thereby causing second connecting plate 39, U-shaped connecting seat 38 and metal ball 35 to perform corresponding actions. Due to the special shape of the annular groove, the metal ball 35 remains stationary while spherical slider 37 moves along the arc groove segment 332. Once spherical slider 37 moves to the V-shaped groove segment 333, the metal ball 35 will exhibit varying degrees of knocking action, especially when spherical slider 37 moves to the second transition segment 3332, the knocking amplitude of the corresponding metal ball 35 is the largest.

[0055] In this invention, the high-frequency striking drive mechanism 30 has a simple structure, is easy to control, and can achieve a striking frequency of 50Hz. In contrast, existing striking structures driven by pneumatic cylinders, electric cylinders, hydraulic cylinders, etc., typically cannot easily reach a striking frequency of 50Hz, or have particularly complex structures; therefore, they are unsuitable for the application scenarios of this invention. Furthermore, because the equipment of this invention is intended for use in the field, overly complex equipment is prone to damage or requires maintenance, making it unsuitable for field use.

[0056] The included angle between the two inclined grooves 3331 is 155°~158°. This included angle cannot be too large, otherwise the metal ball 35 will not be able to strike the protrusion 14 better; this included angle cannot be too small, otherwise, during the rotation of the turntable 33, more serious wear will easily occur at the V-shaped groove section 333.

[0057] The acoustic wave disperser body 10 adopts an existing long-range directional acoustic wave disperser (such as the M series from Jining Yuze Industrial Technology Co., Ltd.). This device achieves its dispersal effect by emitting high-intensity, stimulating sound waves. Within a certain coverage angle, it emits a powerful, loud, and extremely high-decibel piercing noise with high sound pressure level, strong directionality, clear sound, and long range, causing discomfort to listeners and thus having a deterrent effect, thereby achieving the purpose of dispersal. Specific parameters are as follows:

[0058] Rated power: 70W; Frequency response (-10dB): 300Hz-5kHz; Maximum sound pressure level: 141dB; Effective dispersal distance (to people) greater than 100 meters.

[0059] However, current long-range directional acoustic dispersers are designed for dispersing crowds. Human anatomy differs greatly from that of animals, especially birds. Therefore, experiments using existing long-range directional acoustic dispersers to disperse animals have yielded unsatisfactory results.

[0060] Animal Sound Wave Dispersion Experiment

[0061] Experiment A: at 600m 2 Twenty cattle were grazed in an experimental field, fed concentrated forage to encourage them to congregate within the field. A disperser (the existing long-range directional sonic disperser, M series from Jining Yuze Industrial Technology Co., Ltd.) was used to disperse the cattle. The experiment showed an effective dispersion distance (for cattle) of 15 meters (assuming a dispersion rate exceeding 90%). The dispersion rate was calculated as 1 - the number of remaining cattle / 20, and the effective dispersion distance refers to the distance from the experimental field. Similarly, experiments with sheep showed an effective dispersion distance of 30 meters, and experiments with pigs showed an effective dispersion distance of 10 meters.

[0062] Experiment B: at 100m 2Thirty pigeons were released into an experimental field, and pigeon feed was used to encourage them to gather within the field. A dispersing device (existing long-range directional sonic dispersing device, M series from Jining Yuze Industrial Technology Co., Ltd.) was used to disperse the pigeons. The re-gathering rate was also monitored. Specifically, if the pigeons re-gathered in the experimental field, a gathering rate exceeding 80% was considered a valid gathering. The gathering rate was calculated as the number of pigeons after gathering / 30. Dispersing device A was then activated again to disperse the pigeons. The number of valid gatherings was counted within one hour. The re-gathering rate was calculated as the number of valid gatherings / 1. Only when the re-gathering rate was less than or equal to 1 was the dispersal at that distance considered valid. Therefore, the experiment found that the effective dispersal distance (for pigeons) was 8 meters (calculated with a dispersal rate exceeding 90% and a re-gathering rate less than or equal to 1).

[0063] In practice, it has been found that while sound waves can usually disperse birds such as pigeons from a distance of 100 meters, causing them to fly away, most birds quickly regroup. Even after repeated sound wave dispersals, the birds quickly regroup again, indicating a very poor dispersal effect. Therefore, it is necessary to calculate the regrouping rate.

[0064] The wildlife acoustic wave disperser uses a high-frequency striking mechanism 30 to strike the protrusion 14 at a high frequency, thereby enabling the acoustic wave disperser body 10 to vibrate at a frequency of 26~43Hz, which effectively improves the focusing effect, directionality and precise dispersal effect of the sound waves.

[0065] As a supplement to existing technologies, sound is usually a sine wave signal, and currently available long-range directional acoustic wave dispersers also typically use sine wave signals. When installing the acoustic wave disperser body 10, the safe distance between the dispersed target and the acoustic wave disperser body 10 is preferably 50m, thereby effectively protecting the acoustic wave disperser body 10 and facilitating its later maintenance and repair.

[0066] In this invention, a specially designed wildlife acoustic repellent is used. While the acoustic repellent body 10 vibrates at a high frequency of 30Hz, the acoustic signals input to the input module within the acoustic repellent body 10 are all sinusoidal signals. After being input through the input module, the sinusoidal signals are amplified by the acoustic amplifier within the acoustic repellent body 10. According to the "Animal Acoustic Repellent Experiment," the effective repelling distance for cattle is increased to 52 meters (previous technology: 15 meters), an increase of over 247%. The effective repelling distance for sheep is increased to 77 meters (previous technology: 30 meters), an increase of over 157%. The effective repelling distance for pigs is increased to 55 meters (previous technology: 10 meters), an increase of over 450%. The effective repelling distance for pigeons is increased to 63 meters (previous technology: 8 meters), an increase of over 687%. The effective repelling distance for crows is increased to 87 meters (previous technology: 19 meters), an increase of over 358%.

[0067] Therefore, it can be seen that by subjecting the body 10 of the acoustic wave disperser to high-frequency vibration, its dispersal effect on animals can be significantly improved, thereby extending the effective dispersal distance.

[0068] When the wild animal is a bird, the sound wave signal input to the input module within the sound wave disperser body 10 is a triangular wave signal. The sound wave disperser body 10 vibrates at a high frequency of 26-31Hz. Multiple field trials have shown that the effective dispersal distance for crows is increased to 151 meters, for magpies to 123 meters, for quails to 105 meters, and for cuckoos to 109 meters. If the sound wave signal input to the input module is a square wave signal, the effective dispersal distance for crows is 92 meters, and for quails to 79 meters. If the sound wave signal input to the input module is a sawtooth wave signal, the effective dispersal distance for crows is 88 meters, and for quails to 62 meters. Therefore, it can be concluded that the triangular wave signal has the best dispersal effect for wild birds. If the acoustic wave disperser body 10 vibrates at a high frequency of 33Hz or higher, although the acoustic wave signal input by the input module inside the acoustic wave disperser body 10 is a triangular wave signal, it has been found through multiple field practices that it cannot effectively disperse crows, quails and magpies. Even with continuous dispersal operations, the birds will still gather again, and the re-gathering rate is greater than 6%.

[0069] When the wild animal is a large mammal, the acoustic signal input to the input module within the acoustic wave dispersor body 10 is a composite wave signal of a bell wave and a sine wave. Large mammals are defined as mammals with a body length exceeding 75cm or a body height exceeding 65cm. The acoustic wave dispersor body 10 vibrates at a high frequency of 33~35Hz. The composite wave signal of the bell wave and the sine wave is as follows: Figure 7 As shown, this is a sine wave with a bell-shaped wave signal superimposed at the crest. Multiple field trials revealed an effective dispersal distance of 114 meters for wild boars, 97 meters for yaks, and 190 meters for wild goats. If the input signal to the module is a trapezoidal wave, the effective dispersal distance is 71 meters for wild boars and 80 meters for yaks. If the input signal is a stepped wave, the effective dispersal distance is 63 meters for wild boars and 83 meters for wild goats. If the input signal is a bell-shaped wave, the effective dispersal distance is 56 meters for wild boars and 55 meters for yaks. Therefore, for large mammals, the composite wave signal of bell-shaped and sine waves provides the best dispersal effect. If the acoustic wave disperser body 10 vibrates at a high frequency of 40Hz or higher, even if the acoustic wave signal input by the input module in the acoustic wave disperser body 10 is a composite wave signal of bell wave and sine wave, the effective dispersal distance for wild boars will not exceed 70 meters.

[0070] When the wild animal is a small mammal, the acoustic signal input to the input module within the acoustic wave dispersor body 10 is a composite wave signal of a sharp pulse wave and a sine wave. Small mammals are defined as mammals with a body length less than 75cm and a body height less than 65cm. The acoustic wave dispersor body 10 vibrates at a high frequency of 41~43Hz. The composite wave signal of the sharp pulse wave and the sine wave is as follows: Figure 8As shown, this is a sine wave with a spike wave superimposed at the crest. Through repeated testing, it was found that the effective dispersal distance for wild dogs is 97 meters, for wild cats 125 meters, and for mice 83 meters. If the input signal to the module is a triangular wave, the effective dispersal distance for wild dogs is 41 meters, for wild cats 57 meters, and for mice 29 meters. If the input signal is a sawtooth wave, the effective dispersal distance for wild dogs is 47 meters, for wild cats 49 meters, and for mice 35 meters. If the input signal is a spike wave, the effective dispersal distance for wild dogs is 33 meters, for wild cats 41 meters, and for mice 20 meters. Therefore, for small mammals, the composite wave signal of a spike wave and a sine wave has the best dispersal effect. If the acoustic repellent body 10 vibrates at a high frequency of 35-36Hz, even if the acoustic signal input to the input module within the acoustic repellent body 10 is a composite signal of a sharp pulse wave and a sine wave, the effective repelling distance for mice is 29 meters. If the acoustic repellent body 10 vibrates at a high frequency of 50Hz or higher, even if the acoustic signal input to the input module within the acoustic repellent body 10 is a composite signal of a sharp pulse wave and a sine wave, the effective repelling distance for mice will not exceed 32 meters. Example

[0071] The wildlife acoustic deterrent also includes a limiting mechanism for limiting the movement trajectory of the upper end of the metal plate 12. The limiting mechanism includes a side plate 20. A rotating shaft 15 is connected between the upper end of the metal plate 12 and the lower end of the first vertical plate 11. The rotating shaft 15 is rotatably connected to the connection between the upper end of the metal plate 12 and the lower end of the first vertical plate 11. An arc-shaped groove 21 adapted to the rotating shaft 15 is provided on the outer side of the side plate 20. The arc-shaped groove 21 has an arc-shaped structure.

[0072] To ensure that the movement trajectory of the acoustic wave diffuser body 10 is more controllable, a limiting mechanism is set up. When the upper end of the metal plate 12 vibrates at high frequency, the rotating shaft 15 limits the movement trajectory of the upper end of the metal plate 12 along the direction defined by the arc groove 21. The rotating shaft 15 adopts a rotating connection to further reduce friction and improve the flexibility of movement. Example

[0073] The outer casing 31 has a side hole on one side for the second connecting plate 39 to move, and the side hole is covered and sealed with a sealing bag; the metal ball 35 and the U-shaped connecting seat 38 are both located on the outside of the outer casing 31; a support rod 32 is fixedly connected to the lower part of the outer casing 31, and a third connecting plate 40 is fixedly installed between the side plate 20 and the outer casing 31.

[0074] The sealing bag is preferably a wear-resistant plastic bag, primarily serving a sealing function. The sealing bag can employ a multi-pleated design, allowing it to move along with the second connecting plate 39. The sealing bag mainly serves a dustproof function. Example

[0075] like Figure 6 As shown, a water tank 50 is installed on the outside of the acoustic wave diffuser body 10, and a solenoid valve 51 is installed at the bottom of the water tank 50. The input end of the solenoid valve 51 is connected to the inner cavity of the water tank 50. An electronic level gauge is installed inside the water tank 50.

[0076] Practical experience has shown that in rainy weather, the impact of rainwater can affect the accuracy of dispersion, especially the noise generated by the impact, which can affect the dispersion effect. Multiple tests have revealed that by installing a water tank 50 on the outside of the acoustic disperser body 10 and controlling the water volume within the tank 50, the impact of noise can be reduced to some extent, thereby mitigating the impact of rainwater.

[0077] Specifically, taking the dispersal of mice as an example, on a rainy day with rainfall of 3-6 mm per hour, a rain shelter was set up at the test site for the dispersal experiment of mice. The sound wave signal input to the input module in the sound wave disperser body 10 was a composite wave signal of sharp pulse wave and sine wave. The sound wave disperser body 10 vibrated at a high frequency of 41-43 Hz. It was found that if the water tank 50 was not used to store water, the effective dispersal distance decreased to 69 meters (83 meters when there was no rain). By controlling the water volume in the water tank 50 to 1 / 3 of the volume of the water tank 50 through the solenoid valve 51 and the electronic level gauge, the effective dispersal distance would increase to 78 meters.

[0078] Therefore, the water volume in the tank 50 can be controlled by the solenoid valve 51 and the electronic level gauge, thereby meeting the need for remote dispersal of different types of animals.

[0079] In Example 2 above, m = a / (a+b), where m varies from 0.05 to 0.5. Mice are remotely dispersed according to the method described in Example 2, and the effective dispersal distance is h. The trend between the change in the value of m and the effective dispersal distance h is shown below. Figure 9 ,Depend on Figure 9 It can be seen that the optimal value of m is 0.21.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
