Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and more specifically, to a device for driving away small animals. Background Technology

[0002] In recent years, the rapid development of technologies such as power distribution network structure optimization and equipment upgrades has made the power grid structure increasingly complex, posing unprecedented challenges to the safe operation of power systems. Small animals entering substations or distribution stations and accidentally triggering related electrical equipment can cause short circuits, grounding incidents, or malfunctions in relay protection devices, posing a significant risk to the safe operation of power systems.

[0003] Currently, various rodent-proof devices are installed in power systems, such as rodent-proof boards, rodent-proof strips, and rodent-proof barriers. However, these traditional devices mostly rely on physical barriers attached to the outside of equipment for rodent prevention. Their disadvantages include low efficiency, susceptibility to damage by small animals, and the need for regular maintenance and replacement by installers. To improve rodent control, infrared detectors can be configured to sense animal activity and immediately activate an alarm if a small animal enters the substation. However, these devices have the following drawbacks: the detection range of infrared detectors is limited, and they are easily obstructed by sunlight or dust, leading to a high false alarm rate; if the infrared detector is damaged, the equipment is vulnerable to animal intrusion, potentially causing power accidents. Therefore, it is necessary to design a new device that can effectively prevent small animal intrusion and provide timely alarms to reduce the risk of power safety accidents caused by small animals.

[0022] Combination Figure 1 As shown, according to a specific embodiment of this application, a device for repelling small animals is provided.

[0023] Specifically, a device for repelling small animals includes: a power-gathering unit 1, a power conversion unit 2, an ultrasonic unit 3, a light-emitting unit 4, and a protective cover 5. The power-gathering unit 1 is composed of two semi-circular structures spliced ​​together, which are used to fix cables. The power-gathering unit 1 has a built-in switchable current transformer that draws power from the cable. The switchable current transformer is electrically connected to the power conversion unit 2. The protective cover 5 is placed at the bottom of the power conversion unit 2. The light-emitting unit 4 and the ultrasonic unit 3 are arranged adjacent to each other. The power conversion unit 2 is electrically connected to the ultrasonic unit 3 and the light-emitting unit 4.

[0024] In this embodiment, as Figure 1 As shown, the device draws power from the cable via a power-taking unit, and a power conversion unit converts the power obtained by the power-taking unit into stable power suitable for use by other units. The ultrasonic unit and the light-emitting unit operate under the drive of the control unit to repel small animals, while the protective cover provides necessary external protection for the device. This design makes full use of the existing cable's power resources, and effectively repels small animals through multiple means of ultrasonic and light signals, while also exhibiting good environmental adaptability.

[0025] Power-taking unit 1 consists of two semi-circular structures that can be joined together to form a complete device that can surround the cable. The main function of power-taking unit 1 is to secure the cable and extract power from the current flowing through it. Power-taking unit 1 incorporates a switchable current transformer, a device that can induce current in the cable without cutting it and convert it into electrical energy usable by other electronic devices. This design allows the device to be easily installed on the cable without any modification to the cable or interruption of its power supply.

[0026] The power conversion unit 2 receives electrical energy from the power extraction unit 1 and converts it into a stable current and voltage suitable for the ultrasonic unit 3 and the light-emitting unit 4. The power conversion unit is the energy management center of the entire device, ensuring a stable power supply for other functional units, thereby achieving the purpose of repelling small animals.

[0027] The ultrasonic unit 3 is responsible for generating and emitting ultrasonic waves. Ultrasonic waves are sound waves with frequencies higher than the range of human hearing, which can effectively repel small animals such as mice and birds without interfering with humans. The ultrasonic unit 3 is electrically connected to the power conversion unit 2 and is driven by the electrical energy provided by the power conversion unit 2.

[0028] The light-emitting unit 4 is used to emit light signals, typically in nighttime or low-light environments, to enhance the repelling effect on small animals. The light-emitting unit 4 is electrically connected to and powered by the power conversion unit 2. The emission mode and color of the light signal can be set via the control unit to achieve the best repelling effect.

[0029] The protective cover 5 is located at the bottom of the power conversion unit 2. Its function is to protect the ultrasonic unit 3, the light-emitting unit 4, and the internal circuit of the power conversion unit 2 from the influence of the external environment, such as dust and water, so as to ensure the stable operation of the device for a long time.

[0030] Furthermore, the outer casing of the power supply unit 1 is equipped with a spring groove, one end of the spring 6 is fixed in the spring groove, and the other end of the spring 6 is in close contact with the cable. The spring 6 is made of stainless steel, and a metal telescopic contact 7 is provided at the end of the spring 6 that is in contact with the cable.

[0031] In this embodiment, the compression spring 6 is a key component in the power extraction unit 1, ensuring tight contact with the cable and improving power extraction efficiency. The stainless steel compression spring 6 offers advantages such as corrosion resistance, high strength, elasticity, and good conductivity. In outdoor and harsh environments, the stainless steel compression spring 6 maintains its structural integrity and functional stability, ensuring long-term reliable operation.

[0032] To accommodate the spring 6, the housing of the power-taking unit 1 is designed with a dedicated spring groove. The shape and size of this groove match the spring to ensure its stable installation inside the power-taking unit 1. One end of the spring 6 is fixed within the spring groove, typically through welding, screw fixing, or press-fitting. This fixation ensures a stable position for the spring 6, while the other end is fitted with a metal telescopic contact 7. The metal telescopic contact 7 contacts the surface of the cable. Due to the elastic force of the spring 6, the metal telescopic contact 7 presses firmly against the cable. Even if the cable experiences slight movement or vibration due to external factors such as wind or gravity, the spring 6 maintains good contact between the contact and the cable, thus ensuring the stability and effectiveness of power extraction. The metal telescopic contact 7 is typically made of a highly conductive metal material, such as copper or silver-plated copper, to ensure efficient power transmission.

[0033] Through the above design, the power extraction unit 1 can non-invasively draw power from the cable by using the compression spring 6 and the metal telescopic contact 7 to make close contact with the cable, thereby providing the necessary electrical energy for the entire device. At the same time, the choice of stainless steel compression spring 6 and the setting of metal telescopic contact 7 also ensure that the power extraction unit 1 can work stably and reliably under various environmental conditions.

[0034] Furthermore, the outer shell of the power supply unit 1 is made of insulating and flame-retardant material, and an anti-slip pad 8 is installed on the inner side of the power supply unit 1. The anti-slip pad 8 is made of PVC material.

[0035] In this embodiment, an anti-slip pad 8 is installed on the inner side of the power-taking unit 1. The function of the anti-slip pad 8 is to increase the friction between the power-taking unit 1 and the cable, preventing the cable from sliding inside the power-taking unit 1. When the power-taking unit 1 is fixed to the cable, the anti-slip pad 8 can ensure that the cable maintains a stable position even when affected by external factors such as wind and vibration, thereby ensuring close contact between the switchable current transformer and the cable and stable power intake.

[0036] Anti-slip mats are typically made of PVC (polyvinyl chloride) because PVC has excellent wear resistance, oil resistance, and anti-slip properties. At the same time, PVC also has a certain degree of flexibility, allowing it to adapt to irregular shapes on cable surfaces and form a good fit, improving the anti-slip effect. Furthermore, PVC is weather-resistant, able to withstand sun and rain in outdoor environments, maintaining the durability of the anti-slip mat.

[0037] By installing a PVC anti-slip pad 8 inside the power-gathering unit 1, the stability between the cable and the power-gathering unit 1 can be significantly enhanced, preventing the cable from sliding inside the device, thereby ensuring the reliability and efficiency of the power-gathering process. This is particularly important for the device in this application, because the outdoor environment is complex and variable, and the design and selection of the anti-slip pad 8 can effectively address these challenges. At the same time, the choice of PVC material also takes into account durability and economy.

[0038] Furthermore, the power conversion unit 2 has a built-in circuit board on which a voltage regulator circuit, a rectifier circuit, and a control chip are installed to provide power to the ultrasonic unit 3 and the light-emitting unit 4. The control chip is programmable.

[0039] In this embodiment, the power conversion unit 2 is the power management center of the entire device. It houses a circuit board integrating various electronic components and circuits, such as voltage regulator circuits, rectifier circuits, and control chips. This board processes the raw electrical energy obtained from the power extraction unit 1 and converts it into stable electrical energy suitable for use by other functional units. The main function of the voltage regulator circuit is to stabilize the input voltage within a preset range to ensure stable output voltage. This is crucial for sensitive electronic devices, such as the ultrasonic unit 3 and the light-emitting unit 4, as voltage fluctuations can lead to unstable operation or even damage to the devices.

[0040] Voltage regulator circuits typically include Zener diodes, voltage regulator ICs such as 7805 and 7812, or other voltage regulators, which convert voltage fluctuations into a stable output voltage. The rectifier circuit converts the alternating current (AC) induced from the cable into direct current (DC). Most electronic devices use DC as their power source; therefore, the rectifier circuit is a crucial component of the power conversion unit 2.

[0041] The rectifier circuit, implemented using a bridge rectifier or half-wave rectifier, converts alternating current (AC) into unidirectional pulsating direct current (DC). This DC power is then further processed by filtering and voltage regulation circuits to provide clean DC energy. The control chip is the core of the power conversion unit, responsible for coordinating and controlling the operation of the entire device. The control chip receives external signals or commands and adjusts the power conversion process accordingly, such as controlling the output voltage of the voltage regulator circuit and adjusting the efficiency of the rectifier circuit.

[0042] More importantly, the programmable nature of the control chip means that it can be customized and upgraded via software to adapt to different working environments or enhance the functionality of the device. For example, the control chip can be programmed to control the ultrasonic unit 3 to emit ultrasonic waves of different frequencies, or to control the light-emitting unit 4 to emit light signals in different modes and colors, thereby achieving more efficient repelling of small animals.

[0043] Overall, the power conversion unit 2 provides stable and controllable power to the ultrasonic unit 3 and the light-emitting unit 4 through its built-in circuit board, voltage regulator circuit, rectifier circuit and programmable control chip. It also has the ability to adjust and optimize according to the environment and needs, ensuring the operational stability and functional flexibility of the entire device.

[0044] Furthermore, the control chip is electrically connected to the ultrasonic unit 3, and the bottom of the ultrasonic unit 3 adopts an open-layout ventilation grid structure.

[0045] In this embodiment, the control chip establishes a signal transmission and control relationship with the ultrasonic unit 3 through an electrical connection. That is, the output terminal of the control chip is connected to the input terminal of the ultrasonic unit 3 through a wire, so that the control chip sends control signals to adjust the frequency, power and other parameters of the ultrasonic unit, so that it can emit a preset ultrasonic mode according to actual needs.

[0046] Because the ultrasonic unit 3 generates heat during operation, especially at high power, an open-type ventilation grille structure is designed at the bottom to prevent heat buildup that could overheat and affect its normal operation. This ventilation grille structure allows for free airflow, helping to effectively dissipate heat from the ultrasonic unit 3 and keeping the equipment within a safe operating temperature range. The ventilation grille structure also reduces the accumulation of dust and other impurities, improving the reliability and lifespan of the equipment.

[0047] Overall, the electrical connection between the control chip and the ultrasonic unit 3 ensures that the device can flexibly control ultrasonic transmission according to the external environment and internal logic, while the open ventilation grid structure at the bottom of the ultrasonic unit 3 ensures effective heat dissipation during long-term operation, preventing overheating and thus maintaining its stability and extending its service life. This design reflects a comprehensive consideration of both functionality and durability.

[0048] Furthermore, the control chip has a built-in first microprocessor, which transmits a first control signal, and the ultrasonic unit 3 transmits at least one frequency-converting ultrasonic wave within a preset frequency range according to the first control signal.

[0049] In this embodiment, the control chip has a built-in first microprocessor. The first microprocessor can generate and transmit a first control signal according to a preset program or algorithm. This control signal contains instructions from the microprocessor to the ultrasonic unit 3, such as parameters like the frequency, duration, and power of the ultrasonic waves emitted by the ultrasonic unit 3. The generation and transmission of the first control signal are based on the calculation results of the microprocessor and the current operating state of the device, which means that the device can flexibly adjust the ultrasonic wave transmission mode to cope with different environments and targets.

[0050] The ultrasonic unit 3 emits at least one frequency-modulated ultrasonic wave within a preset frequency range according to a first control signal. Frequency-modulated ultrasonic waves refer to ultrasonic waves whose frequency changes according to a preset pattern within a certain time period; this change can be periodic or non-periodic. By emitting at least one frequency-modulated ultrasonic wave within a preset frequency range, the ultrasonic unit 3 can prevent small animals from adapting to a fixed ultrasonic wave frequency, improving the repelling effect. Furthermore, it can utilize multiple frequencies of frequency-modulated ultrasonic waves to repel different types of animals.

[0051] By using a first microprocessor and a first control signal, the control chip can precisely and flexibly control the ultrasonic unit to emit frequency-converted ultrasonic waves. This design enables the device to respond more efficiently and intelligently to the intrusion of small animals.

[0052] Furthermore, the control chip is electrically connected to the light-emitting unit 4. The control chip emits a second control signal, and the light-emitting unit 4 emits light signals of multiple colors according to the second control signal. The second control signal controls the duration of each color light signal among the multiple color light signals and controls the interval between switching different colors of light signals among the multiple color light signals.

[0053] In this embodiment, the control chip establishes a communication connection with the light-emitting unit 4 via wires or other electronic connections, thereby sending a second control signal to the light-emitting unit 4 to control the operating state of the light-emitting unit, including parameters such as the emission, color, and duration of light signals. Upon receiving the second control signal, the light-emitting unit 4 emits preset light signals of various colors according to the instructions in the signal. These colors can be yellow, green, blue, etc., and by alternating or combining their emission, different light signals with different effects can be produced. For example, alternating emission of different colors of light can attract and distract the attention of small animals, thereby reducing their interference with the power grid.

[0054] The second control signal contains not only the color command for the emitted light signal but also the duration of each color signal. This means the control chip can set how long each color light signal is emitted; for example, a yellow light signal lasts for 3 seconds, a green light signal for 2 seconds, and a blue light signal for 1 second. This precise control allows for dynamic changes in the light signal. In addition to controlling the duration of each color light signal, the second control signal can also control the switching interval between different colors. For example, after the yellow light signal ends, there might be a 0.5-second interval before switching to the green light signal. This interval can be used to control the rhythm of the light signal or to achieve a specific light signal pattern.

[0055] In this way, the control chip can precisely control the emission of multiple colors of light signals from the light-emitting unit 4, as well as the duration and switching interval of these light signals, thereby achieving dynamic and intelligent control of the light signals. This control method enhances the attraction effect of the light signals, playing an important role in repelling small animals and protecting the normal operation of the power distribution network. Furthermore, by flexibly adjusting the parameters of the light signals, the effectiveness of their use can be optimized in different scenarios, improving the adaptability and efficiency of the animal-repelling alarm device.

[0056] Furthermore, an optical sensor for detecting light intensity is provided on the outside of the power conversion unit 2. The power conversion unit 2 is electrically connected to the optical sensor. The control chip receives the electrical signal from the optical sensor. The control chip has a built-in second microprocessor. The second microprocessor emits a third control signal based on the electrical signal. The light-emitting unit 4 emits light signals of various colors with different light intensities according to the third control signal.

[0057] In this embodiment, an optical sensor for detecting light intensity is disposed on the outside of the power conversion unit 2. Optical sensors can sense the light intensity of the surrounding environment and typically include photoresistors, photodiodes, phototransistors, etc. These sensors convert light intensity into electrical signals for reading and processing by electronic devices. Placing the optical sensor on the outside of the power conversion unit ensures it is in direct contact with ambient light, thereby enabling more accurate detection of light intensity. Through the electrical connection between the power conversion unit 2 and the optical sensor, the power conversion unit 2 can transmit the light intensity signal detected by the sensor to the control chip for further processing and analysis.

[0058] The control chip receives electrical signals from the optical sensor, reflecting the current ambient light intensity. The control chip converts this signal into data that can be processed by the second microprocessor to adjust the operating mode of the light-emitting unit 4 according to the ambient light intensity. The second microprocessor handles the control logic related to light intensity. Based on the electrical signals received from the optical sensor, the second microprocessor generates a third control signal. If the current ambient light intensity is low, the second microprocessor may generate a third control signal to increase the brightness of the light-emitting unit; if the ambient light is already strong, the second microprocessor may generate a third control signal to reduce the brightness of the light-emitting unit or turn off certain light colors to avoid wasting power or generating unnecessary light pollution.

[0059] The light-emitting unit 4 emits multiple colors of light signals with different illumination intensities according to the third control signal. Upon receiving the third control signal, the light-emitting unit 4 adjusts the intensity of the light signal according to the instructions of the third control signal. For example, if the third control signal indicates that brightness needs to be increased, the light-emitting unit 4 will increase the intensity of the light output; if the control signal indicates that brightness needs to be decreased, the light-emitting unit 4 will decrease the intensity of the light output. Simultaneously, the light-emitting unit 4 can still emit multiple colors of light signals, and through the control of the second microprocessor, the intensity of different colors of light signals can be independently adjusted.

[0060] In this way, the device can automatically adjust the intensity of the light signal emitted by the light-emitting unit 4 according to the light intensity of the surrounding environment, so that the light-emitting unit 4 can maintain the best light-emitting effect under various lighting conditions. This not only improves the energy efficiency of the device, but also reduces the interference to the environment, reflecting the design considerations of the device in terms of intelligence and environmental adaptability.

[0061] Furthermore, the protective cover 5 is transparent and made of insulating PVC material.

[0062] In this embodiment, the protective cover 5 is transparent, allowing light to pass through without blocking or absorbing it. For the light-emitting unit 4, the transparent protective cover 5 ensures that the light signal emitted by the light-emitting unit 4 can propagate unimpeded to the external environment, achieving optimal visual effect and warning range. The transparent protective cover 5 protects the internal components while ensuring the normal functioning of the device remains unaffected. The protective cover 5 is made of PVC (polyvinyl chloride), a material with excellent insulation properties, effectively preventing short circuits or leakage in the internal circuits of electrical equipment due to moisture, dust, or other external factors. PVC also has advantages such as good weather resistance, resistance to aging, and low cost, making it suitable for outdoor or harsh environments. Furthermore, PVC has a certain degree of flexibility, providing cushioning protection for internal components and reducing the impact of accidental impacts or vibrations on the internal circuits.

[0063] By using a transparent and insulating PVC protective cover 5, the normal propagation of the light signal from the light-emitting unit 4 is ensured, while also providing effective protection for the internal circuitry. This avoids the influence of the external environment on the circuitry, enhancing the stability and safety of the device. Furthermore, the choice of PVC material also considers a balance between cost and durability, making it more suitable for long-term outdoor use.

[0064] Furthermore, both the ultrasonic unit 3 and the light-emitting unit 4 receive remote working signals sent by the target terminal wirelessly.

[0065] In this embodiment, the ultrasonic unit 3 and the light-emitting unit 4 receive remote operating signals from the target terminal wirelessly, eliminating the need for physical connections such as wires. Instead, they receive control signals via wireless communication technologies such as Bluetooth, Wi-Fi, RFID, and infrared. This wireless receiving method offers greater flexibility and convenience, allowing users to remotely control the device's operation from anywhere, using a mobile phone, computer, or other target terminal with wireless communication capabilities. The target terminal refers to the device used by the user to send control signals; it can be a mobile phone, tablet, remote control, computer, etc. Through the target terminal, the user can send remote operating signals to the device, which include control commands such as turning the ultrasonic waves on or off, and adjusting the brightness and color mode of the light-emitting unit.

[0066] Both the ultrasonic unit 3 and the light-emitting unit 4 are equipped with wireless receiving modules, which can independently receive and analyze remote working signals. Upon receiving a signal, they will adjust their respective working states according to the instructions in the signal. For example, the ultrasonic unit 3 will adjust the transmission frequency and power of the ultrasonic waves according to the received signal, and the light-emitting unit 4 will adjust the color and brightness of the light signal according to the received signal.

[0067] By wirelessly transmitting remote operating signals, users can remotely control the ultrasonic unit 3 and the light-emitting unit 4 within the device, enabling flexible adjustments to its functions. This not only improves the ease of use and operational safety of the device but also allows for its application in a wider range of scenarios. For example, users can control the device's operation through a target terminal application without being near electrical equipment, avoiding potential electric shock risks. Simultaneously, the remote control function simplifies device maintenance and monitoring, allowing staff to remotely understand and adjust the device's status without frequent on-site visits, thus improving work efficiency and safety.
