Detailed Implementation

[0018] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0019] like Figure 1-6 As shown, this embodiment provides a current-sensing power-harvesting luminous obstacle sphere, including a sphere shell 1, a light-emitting module 2, a current-sensing power-harvesting module 3, an energy storage buffer module 4, an intelligent control module 5, and a power transmission line conductor 6. The specific structure and connection relationship of each component are as follows: The spherical outer shell 1 is composed of two hemispherical shells joined together by bolts. A sealing ring is provided at the joint to enhance the sealing performance and prevent dust and moisture from entering the interior. The spherical outer shell 1 is injection molded in one piece and is made of a mixture of UV-resistant polycarbonate and glass fiber. It is lightweight, high-strength, and easy to install at high altitudes. Its surface is coated with a fluorocarbon weather-resistant anti-corrosion coating, which can resist ultraviolet radiation, rain and snow erosion, and strong wind impact, and adapt to the harsh environment of outdoor high-voltage transmission lines. The contact position between the spherical outer shell 1 and the transmission line conductor 6 is covered with an aluminum clip 13. The aluminum clip 13 is made of aluminum alloy material that has been insulated. It can not only enhance the fixing effect between the spherical outer shell 1 and the conductor, but also play an insulating role to prevent high voltage from damaging the internal components of the obstacle ball.

[0020] The top of the spherical shell 1 is provided with an inwardly extending box structure 11. The box structure 11 is integrally molded with the spherical shell 1. The intelligent control module 5 is installed in the box structure 11 by bolts. The bottom of the box structure 11 is provided with a detachable cover plate 12. The cover plate 12 is connected to the box structure 11 by buckles, which facilitates the installation, maintenance and replacement of the intelligent control module 5. At the same time, it can protect the intelligent control module 5 from dust, water and vibration.

[0021] The light-emitting module 2 includes a light strip 21 and a reflective strip 22. The light strip 21 is preferably a flexible LED light strip 21, with 2-6 strips evenly arranged along the meridian direction of the spherical shell 1. The flexible LED light strip 21 is attached to the inner surface of the spherical shell 1 with high-temperature resistant double-sided adhesive, ensuring a tight fit and better light transmission. The reflective strip 22 is preferably made of high-brightness reflective film, with the same width as the light strip 21. It is alternately arranged with the light strip 21, i.e., one reflective strip 22 is set between every two light strips 21. The reflective strip 22 can reflect sunlight during the day and reflect and diffuse the light emitted by the light strip 21 at night, expanding the warning range and ensuring that the aircraft can clearly see the warning light from different angles.

[0022] The current-sensing power extraction module 3 is clamped onto the transmission line conductor 6 and includes a base 31, a lower magnetic core shell 32, an upper magnetic core shell 37, an induction coil 30, a lower wire clamp 33, an upper wire clamp 35, a locking screw 36, a rubber pad 34, and a rectifier and voltage regulator circuit. The base 31 is made of aluminum alloy and is fixed to the inner wall of the spherical outer shell 1 by screws, located on one side of the box structure 11. The base 31 has an installation cavity inside, and the energy storage buffer module 4 is installed in the installation cavity. Both the lower magnetic core shell 32 and the upper magnetic core shell 37 are made of silicon steel sheets. The lower magnetic core shell 32 is fixed... The upper magnetic core shell 37 is fixed on the top of the base 31 and is hinged to the lower magnetic core shell 32 via a hinge. It can be opened and closed around the hinge. After the two are engaged, they form a closed annular magnetic circuit. The inner diameter of the annular magnetic circuit matches the outer diameter of the transmission line conductor 6, so that it can fit the conductor tightly. The induction coil 30 is made of copper core enameled wire wound on the magnetic circuit formed by the lower magnetic core shell 32 and the upper magnetic core shell 37. The number of turns is 1000-1500. When current flows through the transmission line conductor 6, an alternating magnetic field is generated. The induction coil 30 generates an induced current in the alternating magnetic field to realize current induction power extraction.

[0023] The lower clamp 33 is fixed to the bottom of the base 31. Both the lower clamp 33 and the upper clamp 35 have arc-shaped grooves on their opposite surfaces. The curvature of the arc-shaped grooves matches the curvature of the transmission line conductor 6, making it easy to fit the conductor. A rubber pad 34 is provided between the lower clamp 33 and the upper clamp 35. The rubber pad 34 is made of aging-resistant rubber and fits into the arc-shaped groove. It can increase the friction between the rubber pad and the conductor, improve the clamping firmness, and at the same time play a buffering role, reducing the impact of conductor vibration on the current sensing power extraction module 3. The locking screw 36 passes through the upper clamp 35 and the lower clamp 33 and is locked by a nut. When the nut is tightened, the upper clamp 35 and the lower clamp 33 move closer to each other, clamping and fixing the transmission line conductor 6, ensuring that there is no relative movement between the current sensing power extraction module 3 and the transmission line conductor 6, and ensuring the stability of power extraction.

[0024] The rectifier and voltage regulator circuit 310 is installed in the mounting cavity of the base 31 and electrically connected to the induction coil 30. It includes a rectifier and filter circuit 3101, an NMOS transistor 3102, an isolation diode 3103, a voltage sampling circuit 3104, and a pulse width modulation controller 3105. The rectifier and filter circuit 3101 uses a bridge rectifier circuit and a capacitor filter circuit to convert the alternating induced current generated by the induction coil 30 into direct current and remove noise from the current. The NMOS transistor 3102 is attached to the inner metal wall of the base 31, using the base 31 as a heat sink. The NMOS transistor 3102 is preferably of model IRFP260N, with its drain electrically connected to the positive output terminal of the rectifier and filter circuit 3101 and its source electrically connected to the power supply bus. The input terminal of the isolation diode 3103 is electrically connected to both the positive output terminal of the rectifier and filter circuit 3101 and the drain of the NMOS transistor 3102, and its output terminal is connected to the energy storage buffer module 4 and the intelligent control module 5. The electrical connection serves as isolation to prevent reverse current flow. The voltage sampling circuit 3104 uses a resistor divider circuit to collect the voltage signal at the output of the isolation diode 3103 in real time and transmit the collected voltage signal to the pulse width modulation controller 3105. The pulse width modulation controller 3105 is preferably an SG3525 model. Its input terminal is electrically connected to the second output terminal of the voltage sampling circuit 3104, and its output terminal is electrically connected to the gate of the NMOS transistor 3102. When the sampled voltage is higher than the preset value, the pulse width modulation controller 3105 outputs a pulse width modulation signal to control the NMOS transistor 3102 to conduct, consuming excess power in the NMOS transistor 3102 and the rectifier circuit. When the sampled voltage is lower than the preset value, it controls the NMOS transistor 3102 to turn off, stopping the return of power, thereby achieving stable control of the output voltage and ensuring that the output voltage is stable at 12V, providing a stable power supply for the energy storage buffer module 4 and the intelligent control module 5.

[0025] The energy storage buffer module 4 is preferably a supercapacitor, model 5.5V / 10F, installed in the mounting cavity of the base 31, and electrically connected to the output terminal of the rectifier and voltage regulator circuit. It stores electrical energy and stabilizes the output voltage. When the current in the transmission line conductor 6 is stable, part of the electrical energy output by the rectifier and voltage regulator circuit directly powers the intelligent control module 5 and the light-emitting module 2, while the other part is stored in the supercapacitor. When the conductor current fluctuates or there is a momentary power outage, the supercapacitor releases the stored electrical energy to maintain a stable power output, preventing the light-emitting module 2 from flashing or going out, and ensuring the continuity of the warning effect. In other embodiments, the energy storage buffer module 4 can also preferably be a rechargeable lithium battery with a capacity of 1000mAh, which can meet the needs of long-term backup power supply.

[0026] The intelligent control module 5 includes a light sensor, a control unit, and a communication unit, installed inside the housing structure 11, and electrically connected to the energy storage buffer module 4 and the light-emitting module 2, respectively. The light sensor is preferably a BH1750 model, used to detect ambient light intensity, with a detection range of 0-65535 lx, converting the detected light intensity signal into an electrical signal and transmitting it to the control unit. The control unit is preferably an STM32F103 microcontroller, with a preset light intensity threshold of 50 lx. When the light intensity detected by the light sensor is below 50 lx, the control unit outputs a control signal to control the light-emitting module 2 to turn on and emit warning light; when the light intensity is above 50 lx, the control unit controls the light-emitting module 2 to turn off, saving energy. The communication unit is preferably a GPRS module, model SIM800C, capable of establishing a wireless communication connection with a remote monitoring platform, reporting the obstacle ball's working status in real time, such as light emission status, power supply voltage, and fault information. It can also receive control commands sent by the remote monitoring platform, such as forced on / off, forced off, and adjustment of the light emission frequency, realizing remote monitoring and control of the obstacle ball.

[0027] In this embodiment, the working process of the current-sensing power-generating luminous obstacle ball is as follows: During installation, open the upper magnetic core shell 37 around the hinge, place the power transmission line conductor 6 in the arc-shaped groove of the lower magnetic core shell 32, close the upper magnetic core shell 37, and tighten the locking screw 36 so that the lower wire clamp 33 and the upper wire clamp 35 clamp and fix the conductor through the rubber pad 34. At the same time, the aluminum clip 13 covers the contact position between the ball shell 1 and the conductor, completing the installation and ensuring that there is no relative movement between the obstacle ball and the power transmission line conductor 6.

[0028] When current flows through the conductor 6 of the transmission line, an alternating magnetic field is generated. The induction coil 30 of the current sensing power extraction module 3 generates an induced current in the alternating magnetic field. The induced current is converted into DC power by the rectifier and filter circuit 3101 of the rectifier and voltage regulator circuit 310, and then output through the isolation diode 3103. The voltage sampling circuit 3104 collects the output voltage signal in real time and transmits it to the pulse width modulation controller 3105. The pulse width modulation controller 3105 controls the conduction and cutoff of the NMOS transistor 3102 according to the sampled voltage to achieve stable control of the output voltage.

[0029] The stable DC power output by the rectifier and voltage regulator circuit 310 is partly used to power the intelligent control module 5, and partly used to charge the energy storage buffer module 4. The energy storage buffer module 4 stores electrical energy and releases electrical energy to maintain a stable power supply when the current of the transmission line conductor 6 fluctuates or there is a momentary power outage.

[0030] The light sensor of the intelligent control module 5 detects the ambient light intensity in real time and transmits the signal to the control unit. The control unit automatically controls the start and stop of the light-emitting module 2 according to the light intensity: at night or when the light is insufficient, the LED light strip 21 of the light-emitting module 2 turns on to emit warning light, and the reflective strip 22 reflects and diffuses the light to expand the warning range; during the day when there is sufficient light, the light-emitting module 2 turns off to save energy.

[0031] The communication unit of the intelligent control module 5 interacts with the remote monitoring platform in real time, reports the working status of the obstacle ball, and sends a fault alarm in a timely manner if a fault occurs, such as abnormal power supply or abnormal light emission. At the same time, it receives control commands from the remote monitoring platform and executes corresponding operations.

[0032] Specific embodiments are provided below. These embodiments are intended to enable those skilled in the art to more fully understand the present invention, but do not limit the present invention in any way.

[0033] Example 1 like Figure 1-6 As shown, this embodiment provides a current-sensing power-harvesting luminous obstacle ball, which includes: a ball shell 1, a light-emitting module 2, a current-sensing power-harvesting module 3, an energy storage buffer module 4, and an intelligent control module 5.

[0034] The spherical outer shell 1 is preferably made of lightweight, high-strength materials (such as engineering plastics or composite materials), and is composed of two hemispherical shells joined together to form a sealed internal space to protect the internal electronic components from wind, rain, snow, and dirt. The surface of the outer shell is coated with a weather-resistant and corrosion-resistant coating to extend its service life in harsh outdoor environments. The contact point between the spherical outer shell 1 and the transmission line conductor 6 is covered with an aluminum clip 13. The aluminum clip 13 serves both as insulation and as an auxiliary fixing structure, stably securing the outer shell to the transmission line conductor 6.

[0035] The light-emitting module 2 includes light strips 21 arranged circumferentially along the inner surface of the spherical shell 1. In this embodiment, the light strips 21 are flexible LED light strips, which are uniformly arranged along the meridian direction of the spherical shell 1. Multiple light strips 21 emit light together, thus achieving 360-degree omnidirectional light emission. To enhance luminous efficiency and uniformity, the light-emitting module 2 also includes reflective strips 22 alternately arranged with the light strips 21. The reflective strips 22 can further reflect and diffuse the light emitted by the LEDs.

[0036] The current-sensing power extraction module 3 is clamped onto the transmission line conductor 6 and is used to extract electrical energy from the conductor current through electromagnetic induction. Figure 6 As shown, the module specifically includes: a base 31, a lower magnetic core shell 32, an upper magnetic core shell 37, an induction coil 30, a lower wire clamping block 33, and an upper wire clamping block 35.

[0037] The base 31 is installed inside the spherical outer shell 1, serving as the mounting foundation for the entire power extraction module. The lower magnetic core shell 32 and the upper magnetic core shell 37 are detachably fastened to the outside of the transmission line conductor 6, forming a closed magnetic circuit around the conductor when closed. The induction coil 30 is wound in the magnetic circuit formed by the lower magnetic core shell 32 and the upper magnetic core shell 37 (usually wound on a single magnetic core shell). When an alternating current flows through the transmission line conductor 6, the resulting alternating magnetic field induces an electromotive force in the closed magnetic circuit, thereby generating a current in the induction coil 30.

[0038] The lower clamp 33 and upper clamp 35 are located below and above the transmission line conductor 6, respectively, and are clamped and fixed to the transmission line conductor 6 by locking screws 36. This structure achieves two functions simultaneously: first, it firmly fixes the entire obstacle ball to the conductor 6, preventing it from sliding or swinging, thus achieving zero relative movement; second, it ensures that the lower magnet core shell 32 and the upper magnet core shell 37 can be tightly closed to form an efficient magnetic circuit. To increase the stability of the clamping, a rubber pad 34 is provided between the lower clamp 33 and the upper clamp 35. The rubber pad 34 can increase the friction with the conductor and buffer vibration.

[0039] like Figure 7 As shown, the current sensing power module 3 also includes a rectifier and voltage regulator circuit 310, which converts the unstable AC power output from the induction coil 30 into stable DC power to supply subsequent circuits. The rectifier and voltage regulator circuit 310 includes: a rectifier and filter circuit 3101, an NMOS transistor 3102, an isolation diode 3103, a voltage sampling circuit 3104, and a pulse width modulation controller 3105.

[0040] The AC output from the induction coil 30 is first converted to DC by a rectifier and filter circuit 3101 (such as a bridge rectifier and capacitor filter). The drain of the NMOS transistor 3102 is connected to the positive output of the rectifier and filter circuit 3101. The input of the isolation diode 3103 is connected to both the positive output of the rectifier and filter circuit 3101 and the drain of the NMOS transistor 3102. The input of the voltage sampling circuit 3104 is connected to the output of the isolation diode 3103 (i.e., on the power supply bus VCC) for real-time sampling of the output voltage. The input of the pulse width modulation controller 3105 is electrically connected to the second output (sampling signal) of the voltage sampling circuit 3104, and its output is electrically connected to the gate of the NMOS transistor 3102.

[0041] Its working principle is as follows: When the load is small or the input energy is too large, causing the VCC voltage of the power supply bus to rise, the voltage sampling circuit 3104 detects the voltage rise and transmits the signal to the pulse width modulation controller 3105. The pulse width modulation controller 3105 outputs a pulse width modulation signal to control the NMOS transistor 3102 to turn on, consuming the excess energy (equivalent to short-circuiting the output of the rectifier filter circuit) or returning it to the input (power supply bus), thereby maintaining the stability of the VCC voltage. When the voltage is normal, the NMOS transistor 3102 is turned off, without affecting normal power supply. This dynamic adjustment method can effectively cope with drastic fluctuations in conductor current.

[0042] The energy storage buffer module 4 is disposed inside the spherical outer shell 1 and is electrically connected to the output terminal of the rectifier and voltage regulator circuit 310. The energy storage buffer module 4 can be a supercapacitor or a rechargeable battery, used to store electrical energy and provide continuous power to the light-emitting module 2 and the intelligent control module 5 when the conductor current is zero or too low, thus achieving stable output. To save space, the energy storage buffer module 4 can be installed in the internal cavity of the base 31.

[0043] The intelligent control module 5 is housed inside the spherical outer shell 1, preferably within a separate box structure 11. The box structure 11 has a removable cover plate 12 at its bottom for easy installation and maintenance. The intelligent control module 5 is electrically connected to the energy storage buffer module 4 and the light-emitting module 2, respectively. Figure 8 As shown, the intelligent control module 5 includes: A light sensor is used to detect ambient light intensity; The control unit automatically controls the opening and closing of the light-emitting module 2 based on the signal from the light sensor, and selects a microcontroller; The communication unit is used to interact with the remote monitoring platform, report operating status (including voltage, current, and LED status), and receive control commands (including forced on / off and modification of flashing frequency). Communication methods can include wireless radio frequency, GPRS, 4G / 5G, etc.

[0044] During installation, first open the spherical outer shell 1, then open the lower magnetic core shell 32 and upper magnetic core shell 37 of the current sensing power extraction module 3. Next, place the entire device across the high-voltage transmission line conductor 6. Then, secure the upper wire clamp 35 and lower wire clamp 33 with the locking screw 36 to firmly fix the transmission line conductor 6, while simultaneously closing the upper and lower magnetic core shells tightly. Finally, close and seal the two hemispherical shells to complete the installation.

[0045] In summary, this invention provides a high-voltage line self-powered obstacle ball with ingenious structure, complete functions, and convenient installation, which solves many pain points in the prior art and has high practical value and broad application prospects.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art.
