Description

Technical Field

[0001] The invention relates to the technical field of bird-repelling devices, and in particular to an ultrasonic physical bird-repelling device. Background Art

[0002] Due to the enhanced environmental awareness in Hainan Prefecture in recent years, the bird damage situation in the line channels is severe. The bird-proof spikes and bird repellers on the existing lines can no longer meet the bird prevention requirements under the new situation. Bird-damage failures still occur from time to time in the line channels under its jurisdiction, and prevention and control are relatively difficult. The bird-proof needle plates installed on the lines in recent years have not been able to completely prevent the occurrence of bird-damage failures on the lines, which has brought new challenges to the safe operation of power lines.

[0003] Traditional bird deterrents, such as installing bird spikes and bird repellents, have reduced interference and damage to power lines to a certain extent. However, faced with the increasingly severe bird infestation, these measures are gradually showing their limitations. Specifically, while bird spikes can prevent birds from directly contacting wires, prolonged use can easily cause casualties and birds can easily adapt and circumvent them. Ultrasonic bird repellents and reflectors are also available, but their effectiveness is often limited by the operating environment, weather conditions, and the adaptability of the bird species. A single method of repelling birds can make it difficult for highly adaptable birds to adapt to frequency variations, making it difficult to maintain long-term effectiveness.

[0004] Due to the inadequacy of these bird prevention measures, bird-related failures within power line corridors in Hainan Prefecture remain frequent. These failures not only increase the operational and maintenance costs of power companies but also threaten the safe and stable operation of the power grid, impacting the reliability and stability of power supply. Furthermore, bird-related failures can cause serious accidents such as fires and short circuits, posing potential threats to the surrounding environment and the safety of residents.

[0005] In summary, developing a new, comprehensive bird-prevention device is an urgent need to address bird damage to power lines in Hainan Prefecture. This device can not only effectively reduce bird-damaged faults and improve line safety, but also address environmental protection and ecological balance, achieving harmonious coexistence between humans and nature. Summary of the Invention

[0006] The present invention aims to address the technical defects of the existing technology and provide an ultrasonic physical bird-repellent device and a method of use. It uses millimeter-wave radar to detect the approach of birds and combines ultrasound and physical knocking to scare the birds, so as to improve the bird-proofing ability of the line, reduce the incidence of bird-damaged faults in the line channel, improve the safety level of line operation, and ensure the power quality of the line.

[0007] The present invention provides the following technical solution: an ultrasonic physical bird-repelling device, comprising a bird repeller and a solar module, wherein the solar module comprises a solar panel, a solar panel bracket and a control module, and the output end of the solar panel is connected to the bird repeller;

[0008] The bird repeller comprises a shell, an ultrasonic component, a millimeter-wave radar and a knocking device. The ultrasonic component is arranged on the outside of the shell, and the millimeter-wave radar and the knocking device are arranged inside the shell.

[0009] Preferably, the ultrasonic component includes a detection module, a microprocessor, a power amplifier and a driving speaker. The microprocessor realizes detection, storage, effect comparison and frequency generation. The microprocessor adopts the RKNN model.

[0010] Preferably, the knocking device includes a second mounting bracket, a reduction motor is fixed on one side of the second mounting bracket, the output shaft of the reduction motor passes through the other side of the second mounting bracket and is connected to a flange coupling, a cam follower is fixed at the circumferential edge of the flange coupling, the middle of the flange coupling is connected to one end of the first connecting rod through a bearing, the other end of the first connecting rod is movably connected to one end of the second connecting rod, the other end of the second connecting rod is connected to the impact shaft, the impact shaft passes through the bottom of the second mounting bracket and is provided with a spring, and a self-lubricating copper sleeve is provided on the outside of the impact shaft.

[0011] Preferably, a radar fixing bracket is provided on the top of the second mounting bracket, and the millimeter wave radar is fixed on both sides of the radar fixing bracket.

[0012] Preferably, the control module includes a mainboard, a power supply and a power adapter module.

[0013] Preferably, the bird repeller further comprises a first mounting bracket, the upper side of the first mounting bracket is connected to the second mounting bracket, and the first mounting bracket is provided with a circular hole corresponding to the position of the impact axis.

[0014] Preferably, a fuse is provided at the bottom of the reduction motor.

[0015] Preferably, the microprocessor includes an ultrasonic generator, the bird-repelling ultrasonic wave frequency range generated by the ultrasonic generator is 20 to 30 kHz, and the random frequency conversion output sound pressure is ≥100 dB.

[0016] To use the ultrasonic physical bird repellent device, follow these steps:

[0017] Step 1: When the millimeter-wave radar detects a bird approaching, the bird repeller emits ultrasonic waves of different frequencies at regular intervals and stores the number of bird activities. If the millimeter-wave radar detects multiple bird activities within a period of time, the control module controls the microprocessor to change the bird repeller frequency, records the number of bird activities again, detects the number of bird activities corresponding to each frequency, screens out the bird repeller frequency range, and generates the corresponding frequency to drive the birds away.

[0018] Step 2: When the millimeter-wave radar detects a bird approaching, the reduction motor drives the impact shaft to strike the surface of the mounting object to drive the bird away.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The ultrasonic physical bird repellent device of the present invention is a device that uses a combination of ultrasonic waves and physical knocking to repel birds. The device includes a solar module, which is composed of a solar panel, a solar panel bracket, and a control module. The output end of the solar panel is connected to the bird repellent. The bird repellent itself includes a housing, an ultrasonic module, a millimeter-wave radar, and a knocking device. The ultrasonic module is installed on the outside of the housing, while the millimeter-wave radar and knocking device are installed inside the housing.

[0021] The invention works as follows: millimeter-wave radar is used to detect the approach of birds. Once a bird is detected, the ultrasonic component and the knocking device are activated. The ultrasonic component emits sound waves that are unpleasant to the birds, while the knocking device creates a frightening effect through physical knocking, forcing the birds to leave. This combination of ultrasonic and physical knocking can effectively improve the bird-repelling effect, especially in power lines and other scenarios where bird repelling is required.

[0022] The use of solar panels ensures that the bird scarer can operate without an external power source, which is especially important for bird scarers installed in remote areas or areas with difficulty in accessing power. The solar panels provide power to the bird scarer under sufficient sunlight conditions, while the control module is responsible for managing the charging and discharging process of the solar panels, ensuring that the bird scarer has enough energy to operate when needed.

[0023] The ultrasonic output frequency of ultrasonic bird repellers is usually above 20kHz. Sound waves of this frequency are invisible to humans and therefore do not cause interference to people. The bird repelling effect of ultrasonic bird repellers may not be immediately apparent, but long-term use can effectively worsen the living environment of birds, thereby achieving the purpose of bird repelling. In addition, the power of ultrasonic bird repellers usually does not cause harm to the human body, so it is considered a safe and environmentally friendly bird repellent method.

[0024] In practical applications, ultrasonic physical bird repellent devices can significantly reduce the incidence of bird damage in line channels, improve the safety level of line operation, and ensure the quality of line power. The installation and maintenance of this device are relatively simple, and due to its eco-friendly characteristics, it is becoming increasingly popular. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0042] like Figures 1 to 11 As shown, it shows a specific embodiment of the present invention: Figures 1 to 11 As shown, the ultrasonic physical bird-repelling device disclosed in the present invention includes a bird repellent 1 and a solar module 2. The solar module 2 includes a solar panel 2-1, a solar panel bracket 2-2 and a control module 2-3. The output end of the solar panel 2-1 is connected to the bird repellent 1.

[0043] The bird repeller 1 includes a shell 1-1, an ultrasonic component 1-2, a millimeter-wave radar 1-3 and a knocking device. The ultrasonic component 1-2 is arranged on the outside of the shell 1-1, and the millimeter-wave radar 1-3 and the knocking device are arranged inside the shell 1-1.

[0044] Preferably, the ultrasonic component 1-2 includes a detection module, a microprocessor, a power amplifier and a driving speaker. The microprocessor realizes detection, storage, effect comparison and frequency generation, and the microprocessor adopts the RKNN model.

[0045] like Figure 10 As shown, the ultrasonic frequency generator inside the system randomly generates a frequency. After power amplification, it drives a speaker to emit sound, activates a strong light, simulates gunshots, and even eagle calls to repel birds. The frequency counts are also stored. If multiple bird movements are detected over a period of time, the frequency generator is controlled to change the frequency, and the number of bird movements is recorded again. By continuously changing the frequency and detecting the number of bird movements corresponding to each frequency, the most suitable ultrasonic frequency for repelling birds can be selected. As birds adapt to the frequency, or if other birds enter the protected area, the number of bird movements detected by radar will increase, and the above process can be repeated to find the most suitable frequency for effective repelling.

[0046] This process uses the existing RKNN model and adjusts the frequency of the ultrasonic generator based on the model's predictions. The RKNN model includes: data collection and preprocessing, feature extraction, and model training. The model is trained using historical data, and prediction performance is optimized by adjusting model parameters (such as weights and learning rates). Real-time prediction data is input into the trained model to predict the most effective ultrasonic frequency under current conditions. Based on the model's predictions, the control unit adjusts the ultrasonic generator frequency. If the results are not satisfactory, new data is collected and the model is retrained to adapt to changes in bird behavior or new bird species.

[0047] At the same time, bird repellent devices periodically emit ultrasonic waves of varying frequencies. These frequencies are beyond the human hearing range and are generally imperceptible to humans. However, birds, with hearing nearly 10 times that of humans, are highly sensitive to sound. The primary purpose of using this timing method is to create an ultrasonic environment that degrades the birds' habitat and makes them uncomfortable.

[0048] Preferably, Figures 5-7 As shown, the knocking device includes a second mounting bracket 1-14, and a reduction motor 1-13 is fixed on one side of the second mounting bracket 1-14. The output shaft of the reduction motor 1-13 passes through the other side of the second mounting bracket 1-14 and is connected to the flange coupling 1-5. A cam follower 1-6 is fixed at the circumferential edge of the flange coupling 1-5. The middle of the flange coupling 1-5 is connected to one end of the first connecting rod 1-7 through a bearing. The other end of the first connecting rod 1-7 is movably connected to one end of the second connecting rod 1-8. The other end of the second connecting rod 1-8 is connected to the impact shaft 1-10. The impact shaft 1-10 passes through the bottom of the second mounting bracket 1-14 and is provided with a spring 1-11. A self-lubricating copper sleeve 1-9 is provided on the outside of the impact shaft 1-10.

[0049] When the device radar detects a bird approaching, the motor drives the knocking component to knock on the surface of the installation object (such as the angle steel of the tower), making a violent knocking sound, thereby scaring the bird away.

[0050] The knocking device is a component of a physical bird-repelling device. It is designed to produce a knocking sound through mechanical action when radar detects a bird approaching, thereby scaring the birds and driving them away from a specific area, such as a power tower or communication tower. The following is a description of the knocking device:

[0051] 1. Second mounting bracket 1-14: This is the fixed part of the striking device, used to mount the entire striking assembly to the bird repeller.

[0052] 2. Reducer motor 1-13: fixed on one side of the second mounting bracket, used to provide power. The speed of the motor can be adjusted through the reduction mechanism to meet the working requirements of the knocking device.

[0053] 3. Output shaft: The output shaft of the reduction motor passes through the other side of the second mounting bracket to transmit power to other parts of the knocking device.

[0054] 4. Flange coupling 1-5: The flange coupling is locked with the motor main shaft and rotates with the motor. It is connected to the end of the output shaft of the reduction motor and is used to transmit torque. The cam follower is fixed on its circumferential edge and is connected to the first connecting rod through a bearing in the middle.

[0055] 5. Cam followers 1-6: Installed on the circumferential edge of the flange coupling, the cam followers are fixed and locked on the flange coupling and move together with the flange coupling.

[0056] 6. First connecting rod 1-7: One end is connected to the middle of the flange coupling through a bearing, and the other end is movably connected to one end of the second connecting rod. It transmits the reciprocating motion of the cam follower to the second connecting rod.

[0057] 7. Second connecting rod 1-8: One end is movably connected to the other end of the first connecting rod, and the other end is connected to the impact shaft. It transmits the movement of the first connecting rod to the impact shaft.

[0058] 8. Impact shaft 1-10: passes through the bottom of the second mounting bracket, and a self-lubricating copper sleeve is provided on its outside to provide a guide for the impact shaft. One end of the impact shaft is connected to the second connecting rod, and the other end extends out of the bottom of the bracket to knock on the surface of the installation object.

[0059] 9. Spring 1-11: Set at the bottom of the second mounting bracket, used to support the impact shaft and provide a reset force during the knocking process.

[0060] 10. Self-lubricating copper sleeve 1-9: It is set on the outside of the impact shaft to provide a guide for the impact shaft, so that the impact shaft can knock the surface of the installation object up and down in the copper sleeve. At the same time, it is set to self-lubricating to reduce the friction between the impact shaft and the bracket, ensuring that the impact shaft can reciprocate smoothly.

[0061] When the radar detects an approaching bird, the reduction motor rotates clockwise, causing the cam follower to rotate the first connecting rod, which in turn drives the second connecting rod clockwise. The second connecting rod then drives the impact shaft upward, compressing the spring. When the first connecting rod is driven to rotate beyond the critical point (12 o'clock), the spring instantly releases pressure, causing the impact shaft to strike downward at high speed against the surface of the mounting object. For example, if mounted on a tower, it strikes the tower angle steel, not the device's mounting bracket. This process drives the impact shaft in reciprocating motion, with one end of the impact shaft striking the surface of the mounting object, producing a knocking sound. This knocking sound scares birds, prompting them to fly away. The entire striking device is designed to achieve the purpose of bird repelling through physical means, rather than chemical or harmful methods, and is therefore considered an environmentally friendly and eco-friendly solution.

[0062] Preferably, Figure 7 As shown, a radar fixing bracket 1-4 is set on the top of the second mounting bracket 1-14, and the millimeter wave radar 1-3 is fixed on both sides of the radar fixing bracket 1-4.

[0063] A radar fixing bracket 1-4 is specially provided on the top of the second mounting bracket 1-14 to fix the millimeter wave radar 1-3 to ensure that the radar can accurately and stably detect bird activities in the surrounding environment;

[0064] The millimeter-wave radars 1-3 are fixed on both sides of the radar fixing bracket 1-4. This layout realizes dual-radar bird detection, that is, the two radars detect the opposite two areas respectively, and the detection direction of the millimeter-wave radars 1-3 is the opposite two sides. This design enables the bird-repelling device to monitor bird activities in all directions and from multiple angles, effectively improving the coverage and accuracy of detection. The maximum detection distance of each millimeter-wave radar can reach 15 meters, which means that the bird-repelling device can detect birds at a longer distance, providing sufficient time for timely adoption of repellent measures.

[0065] Working Principle: Millimeter-wave radar detects bird activity in the surrounding environment by transmitting and receiving millimeter-wave signals. When a bird enters the radar's detection range, the radar receives the reflected signal and calculates the bird's position, speed, and other parameters. The control module then activates repellent devices such as ultrasonic components or knocking devices based on these parameters and a preset repelling strategy to repel the bird.

[0066] Radar is a detector that combines microwave transmitters and receivers. Its operating principle is based on the Doppler effect. Microwaves have very short wavelengths, ranging from 1mm to 1000mm, making them easily reflected by objects. When microwave signals reflect off moving objects, the Doppler effect occurs, causing a slight shift in frequency between the reflected microwave signal and the transmitted signal. This signals an object entering the defense zone.

[0067] Using the principles of Doppler radar, the microwave transmitting and receiving antennas are integrated. A field-effect transistor (FET) serves as a solid-state microwave oscillator, combined with a waveguide to form a compact microwave signal transmitter. A Schottky detector in the probe and the same waveguide form a single-tube waveguide mixer, acting as a receiver. This mixer mixes the signal coupled back from the transmitting source, generating a frequency difference that is then processed by a low-frequency amplifier and controls the alarm output. Due to their short wavelength, microwave electromagnetic waves have strong penetrating power and can penetrate non-metallic materials such as glass, wood, and brick walls.

[0068] This design constitutes an efficient and accurate bird detection system, providing strong support for the intelligent control of bird repellent devices.

[0069] Preferably, Figures 8-9 As shown, the control module 2-3 includes a mainboard 2-3-1, a power supply 2-3-3 and a power adapter module 2-3-2.

[0070] The control module is not only responsible for managing the charging and discharging process of the solar panel to ensure that the bird repeller can work stably even when there is insufficient sunlight or at night, but also includes a control circuit for the knocking device to achieve a precise physical repeller effect. The device can be powered by solar energy and AC 220V.

[0071] The power module is responsible for converting the electrical energy converted by the solar panels or the electrical energy stored in the battery into the voltage and current required by the control module and the various components of the bird repeller. It includes voltage stabilization circuits, filtering circuits, etc. to ensure the stability and reliability of power supply.

[0072] The power adapter module bridges the gap between the solar panel and the motherboard. It's responsible for initial processing of the solar panel's output (such as voltage conversion and current limiting) before safely supplying it to the motherboard. It may also have a charging management function, automatically charging the battery when excess solar panel power is generated and automatically switching to battery power when solar power is insufficient.

[0073] Control module charging and discharging management:

[0074] Monitor the output status of the solar panels in real time and adjust the charging current and voltage as needed to ensure safe and efficient charging of the battery.

[0075] When needed, it automatically switches to battery power supply mode to provide stable power support for the bird repeller.

[0076] Percussion device control:

[0077] The control circuit of the integrated knocking device accurately controls the working timing and strength of the knocking device according to the detection results of the millimeter-wave radar and the preset expulsion strategy.

[0078] The sudden sound and vibration produced by physical knocking will have a strong scaring effect on approaching birds, forcing them to stay away from the bird-proof area.

[0079] In summary, the control module plays a vital role in the ultrasonic physical bird repellent device. It not only ensures the stable operation and efficient work of the entire system, but also achieves effective bird repellent through precise control logic and strategy.

[0080] Preferably, Figure 5 As shown, the bird repeller 1 further includes a first mounting bracket 1-12, the upper side of the first mounting bracket 1-12 is connected to the second mounting bracket 1-14, and a circular hole corresponding to the position of the impact axis 1-10 is opened on the first mounting bracket 1-12.

[0081] In the bird repellent 1 of the present device, the first mounting bracket 1-12 and the second mounting bracket 1-14 play a key role in fixing and mounting.

[0082] 1. The second mounting bracket 1-14: This bracket is the fixed part of the striking device. Its main function is to firmly mount the entire striking assembly to the bird repeller.

[0083] 2. The first mounting bracket 1-12: Its main function is to install the entire bird repeller on the iron tower angle steel. The first mounting bracket 1-12 is provided with a circular hole corresponding to the position of the impact shaft 1-10. The design of this circular hole is very critical because it allows the impact shaft to directly hit the iron tower angle steel, generating sound and vibration to drive away birds.

[0084] The design of the bird repeller takes into account the convenience and practicality of installation. Through the use of two mounting brackets, the bird repeller can be easily installed on the iron tower. Through the sound and vibration generated by the impact shaft hitting the iron tower angle steel, the bird repeller can effectively drive away birds without harming them.

[0085] Preferably, Figure 7 As shown, a fuse is provided at the bottom of the reduction motor 1-13.

[0086] The practice of providing a fuse at the bottom of the reduction motor 1-13 is mainly for the consideration of motor protection and circuit safety.

[0087] A fuse is a safety device in an electrical circuit. Its primary function is to automatically blow when an overcurrent occurs, thereby shutting off the circuit and preventing damage to the motor or other electrical equipment caused by excessive current. For geared motors, fuses can quickly respond to abnormal conditions such as motor overload and short circuits, protecting the motor from damage. Fuses also have a certain load-carrying capacity, meaning they can withstand normal current fluctuations and transient pulses in the circuit. During the operation of a geared motor, current fluctuations and pulses are generated in the circuit due to load changes, start-up and stop operations, and other factors. Fuses need to have a certain pulse-withstanding capability to ensure they do not accidentally blow under these conditions.

[0088] Mounting the fuse at the bottom of the geared motor is a reasonable option. This ensures the fuse can directly monitor the current in the motor circuit and quickly cut off the circuit when necessary. Bottom mounting also facilitates heat dissipation and maintenance.

[0089] In summary, installing a fuse at the bottom of the geared motor 1-13 is an effective motor protection measure. By properly selecting and installing the fuse, you can ensure that the geared motor is protected in an abnormal situation, preventing the fault from escalating and damaging the device.

[0090] Preferably, the microprocessor includes an ultrasonic generator, the bird-repelling ultrasonic wave frequency range generated by the ultrasonic generator is 20 to 30 kHz, and the random frequency conversion output sound pressure is ≥100 dB.

[0091] The ultrasonic generator integrated into the microprocessor is responsible for generating high-frequency ultrasonic waves. The frequency range of these ultrasonic waves is set to 20-30kHz, a range that is based on a comprehensive consideration of bird hearing characteristics and bird repellent effectiveness. Under the control of the microprocessor, the ultrasonic generator can precisely adjust the frequency and output sound pressure of the ultrasonic waves to suit different bird repellent needs and environmental conditions.

[0092] The ultrasonic generator's frequency range is set at 20-30kHz, based on extensive experimental data and research on bird hearing characteristics. Ultrasonic waves within this range are inaudible to humans, but have a significant repelling effect on birds.

[0093] Random Frequency Variable: In addition to the base frequency range, the ultrasonic generator also features random frequency variable. This means the ultrasonic frequency varies randomly within a certain range, preventing birds from adapting to a single frequency. This random frequency variable feature further enhances the bird repellent effect, making it difficult for birds to adapt to and become accustomed to the ultrasonic repellent.

[0094] The experiment passed Figure 11 The bird repelling time comparison chart of different frequency bands records data and qualitatively compares the bird repelling effects of ultrasonic waves in different frequency bands. Figure 11 In the comparison of bird-repelling time at different frequency bands, the horizontal axis represents the order in which sparrows appeared in the experiment, and the vertical axis represents the bird-repelling time. Figure 11 From the comparison chart of bird-repelling time in different frequency bands, it can be seen that the bird-repelling time of 30kHz and random frequency ultrasonic waves is significantly lower than that of other frequency bands, so these two methods have better bird-repelling effects.

[0095] The output sound pressure of the ultrasonic generator is set to ≥100dB. This is to ensure that the ultrasonic wave has sufficient strength and penetration to cover a wider area and effectively repel birds. High output sound pressure can also increase the intensity of the ultrasonic wave stimulation to birds, improving the repelling effect.

[0096] Frequency Effect Comparison: Experimental results show that 30kHz ultrasonic waves and random frequency ultrasonic waves are more effective in repelling birds. This is because ultrasonic waves in these frequency ranges can more effectively interfere with the birds' auditory systems, causing them to feel uncomfortable and stay away from the target area.

[0097] Comprehensive effect evaluation: In addition to frequency selection, factors such as ultrasonic output sound pressure, duration, and waveform also affect bird repellent effectiveness. Therefore, in actual application, comprehensive evaluation and adjustment are required based on the specific environment and bird repellent needs to achieve the best bird repellent effect.

[0098] In summary, the ultrasonic generator in the microprocessor effectively repels birds by generating ultrasonic waves of a specific frequency and output sound pressure, combined with random frequency conversion characteristics. This physical bird repellent method has the advantages of being environmentally friendly, harmless, and long-lasting.

[0099] To use the ultrasonic physical bird repellent device, follow these steps:

[0100] Step 1: When the millimeter-wave radar 1-3 detects a bird approaching, the bird repellent 1 regularly emits ultrasonic waves of different frequencies and stores the number of bird activities. When the millimeter-wave radar 1-3 detects multiple bird activities within a period of time, the control module 2-3 controls the microprocessor to change the bird repelling frequency, records the number of bird activities again, detects the number of bird activities corresponding to each frequency, screens out the bird repelling frequency range, and generates the corresponding frequency to repel the birds;

[0101] Step 2: When the millimeter wave radar 1-3 detects a bird approaching, the reduction motor 1-13 drives the impact shaft 1-10 to strike the surface of the mounting object to drive away the bird.

[0102] The ultrasonic physical bird repellent device uses millimeter-wave radar to detect the approach of birds, and combines ultrasound and physical knocking to scare the birds, so as to improve the line's bird-proofing ability, reduce the incidence of bird-damaged faults in line channels, improve the safety level of line operation, and ensure the quality of line power.

[0103] Step 1: Ultrasonic Bird Repellent and Intelligent Frequency Adjustment

[0104] When the millimeter-wave radar detects birds approaching the preset protection area, the system will be activated immediately. Due to its high precision and high penetration, the millimeter-wave radar can effectively identify and track the flight path of birds. The bird scarer will then emit ultrasonic waves of different frequencies at regular intervals. These ultrasonic frequencies are usually selected within the auditory sensitivity range of birds, but are harmless to humans and most other animals. At the same time, the system will store the number of bird activities detected to provide a data basis for subsequent analysis.

[0105] Intelligent frequency adjustment: If the millimeter-wave radar continuously detects multiple bird activities over a period of time, it means that the currently used ultrasonic frequency may not be effective enough or the birds have gradually adapted. At this time, the control module will receive the signal and instruct the microprocessor (built into the control module) to adjust the frequency. The microprocessor will change the ultrasonic frequency emitted by the bird repeller and record the number of bird activities again. Through multiple attempts and adjustments, the system is able to detect and record the number of bird activities corresponding to each frequency, thereby screening out the most effective bird-repelling frequency range. Once the most effective frequency range is determined, the system will automatically generate and continuously emit ultrasonic waves of these frequencies to effectively repel birds.

[0106] Step 2: Mechanical impact assisted bird repellent

[0107] If ultrasonic bird repellent alone is not effective, or if you encounter particularly stubborn birds, the system will also activate a mechanical impact-assisted bird repellent mechanism.

[0108] When the millimeter-wave radar detects a bird approaching again, the reduction motor will be activated. Through its stable rotation and deceleration function, the reduction motor drives the impact shaft to perform precise and powerful knocks.

[0109] The impact shaft strikes the surface of the mounting object, producing a noticeable sound and vibration. This sudden sound and vibration can further scare birds and force them to fly away from the area.

[0110] The combination of mechanical impact and ultrasonic bird repellent creates a double repellent effect, greatly improving the efficiency of bird repellent.

[0111] This ultrasonic physical bird repellent device combines advanced millimeter-wave radar detection technology, intelligent frequency adjustment technology, and a mechanical impact-assisted mechanism to achieve efficient and non-harmful bird repellency. Its simple and convenient operation, coupled with the ability to flexibly adjust its strategy based on actual conditions, makes it an ideal choice for protecting specific areas from bird infestations.
