Description

Technical Field

[0001] This invention relates to the field of insulator technology, and in particular to a de-icing system for porcelain insulators. Background Technology

[0002] Porcelain insulators, widely used insulating components in power systems, play a crucial role in ensuring the safe and stable operation of power transmission. However, in cold regions during winter or in severe weather such as freezing rain, ice easily accumulates on the surface of porcelain insulators. The presence of ice not only increases the weight of the porcelain insulators, leading to a significant increase in their mechanical load and potentially causing mechanical failures such as breakage, but also alters their electrical properties, reduces their insulation level, and increases the probability of electrical accidents such as flashover, seriously threatening the safe operation of the power system. To solve this problem, porcelain insulator de-icing systems have emerged. These systems aim to remove the ice layer from the surface of porcelain insulators in a timely and effective manner using specific technical means, restoring their normal mechanical and electrical properties and ensuring reliable power supply from the power system. Currently, there are various types of porcelain insulator de-icing systems, including mechanical de-icing, thermal de-icing, and electronic de-icing, each based on different principles to achieve its de-icing function.

[0003] While existing porcelain insulator de-icing systems can meet basic de-icing needs to a certain extent, they still exhibit numerous limitations in practical applications. Taking mechanical de-icing systems as an example, they typically remove ice by manual tapping or vibration using mechanical devices. While relatively simple to operate, this method is inefficient, requiring significant manpower and time, especially when dealing with large groups of porcelain insulators, making rapid and comprehensive de-icing difficult. Furthermore, the quality of manual operation is difficult to guarantee, potentially damaging the porcelain insulators due to uneven tapping force. Thermal de-icing systems use heating elements to heat the porcelain insulators, melting the ice. However, this system consumes a lot of energy, and the heating process may generate thermal stress on the internal structure of the porcelain insulators, potentially affecting their lifespan in the long run. Electronic de-icing systems utilize high-frequency electric fields or pulsed currents to break and remove the ice, but this system has high equipment requirements, high technical complexity, and relatively high cost. Moreover, it may be affected by electromagnetic interference during actual operation, impacting the de-icing effect.

[0004] In order to at least solve one of the above-mentioned technical problems, the present invention aims to provide a porcelain insulator de-icing system to further improve the de-icing effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A porcelain insulator de-icing system includes a drone platform. A horizontally positioned first telescopic component is mounted on the drone platform. A mounting base is fixedly connected to the movable part of the first telescopic component. Clamping arc plates are fixedly connected to both sides of the mounting base via horizontally positioned second telescopic components. A heating groove is formed on the side of the clamping arc plate facing the insulator, and the heating groove is adapted to a partial side of the insulator. An electric heating mesh is provided on the inner wall of the heating groove, and a closed heat-conducting layer is provided on the outer surface of the electric heating mesh. A horizontally positioned ice-crushing mechanism is provided on the side of the mounting base facing the insulator. The ice-crushing mechanism includes a third telescopic component connected to the mounting base, and ice blocks are connected to the movable part of the third telescopic component via a spring telescopic rod.

[0007] Preferably, the first telescopic component, the second telescopic component, and the third telescopic component are all configured as electric cylinders driven by servo motors.

[0008] Preferably, the ice crushed blocks are spherical, hemispherical, or conical.

[0009] Preferably, the spring telescopic rod includes a fixed tube fixedly connected to the third telescopic component, a movable rod slidably connected to the inner wall of the fixed tube, the bottom of the movable rod being connected to the bottom of the fixed tube by a buffer spring, and one end of the movable rod being fixedly connected to the crushed ice.

[0010] Preferably, the clamping arc plate has an internal airflow channel, and an air supply component is fixedly installed on the back of the clamping arc plate. The air outlet of the air supply component is connected to the airflow channel. The clamping arc plate has multiple hot air nozzles evenly distributed on the outside of the heating groove. The hot air nozzles are connected to the airflow channel, and one side of the airflow channel is the back of the electric heating grid. The airflow passes sequentially through the air supply component, the airflow channel, the electric heating grid, and the hot air nozzles, with the hot air nozzles facing the insulator.

[0011] Preferably, the air supply component is an electric air pump.

[0012] Preferably, the air inlet of the air supply component and the outlet of the hot air nozzle are provided with dustproof nets.

[0013] Preferably, the unmanned aerial vehicle platform is equipped with landing gear at the bottom for stable flight.

[0014] Preferably, the outer surface of the sealed thermally conductive layer is coated with an anti-slip coating.

[0015] The present invention has the following beneficial effects:

[0016] I. Improved De-icing Efficiency and Effectiveness: This porcelain insulator de-icing system utilizes a drone platform equipped with a de-icing device, enabling rapid access to the porcelain insulators. Especially for large groups of porcelain insulators or areas difficult to reach manually, it achieves rapid and comprehensive de-icing operations, overcoming the shortcomings of low efficiency and incomplete coverage of mechanical de-icing. Through the coordinated operation of the first, second, and third telescopic components, the positions of the clamping arc plate and the ice-crushing mechanism can be precisely adjusted, ensuring a tight fit between the heating groove of the clamping arc plate and the local side of the insulator. The electric heating network melts the ice layer, while the ice-crushing mechanism uses ice blocks connected by spring-loaded telescopic rods to break up the ice. This combination of multiple de-icing methods significantly improves the de-icing effect, more promptly and effectively removing the ice layer from the surface of the porcelain insulators, restoring their normal mechanical and electrical properties, and ensuring reliable power supply to the power system.

[0017] II. Reduced Damage to Porcelain Insulators: Mechanical de-icing methods often damage porcelain insulators due to uneven manual striking force. This system employs a gentler and more precise de-icing method. The clamping arc plate uses heating grooves adapted to the side of the insulator for heating and de-icing. The ice-crushing mechanism, under the action of a spring-loaded telescopic rod, can flexibly adjust the impact force according to the ice layer, avoiding mechanical damage to the porcelain insulator due to excessive force. Furthermore, the outer surface of the sealed heat-conducting layer is coated with an anti-slip coating, increasing friction with the insulator during clamping and preventing slippage and scratches on the insulator surface, further protecting the porcelain insulator.

[0018] III. Reducing Energy Consumption and Thermal Stress Impact: Thermal de-icing systems consume a lot of energy and may cause thermal stress to the internal structure of porcelain insulators, affecting their service life. In this system, an airflow channel is set inside the clamping arc plate. The air supply component blows airflow sequentially through the airflow channel, the electric heating grid, and hot air nozzles onto the insulator. This hot air-assisted heating method can improve thermal energy utilization efficiency and reduce energy consumption to a certain extent compared to relying solely on electric heating grid heating. At the same time, the hot air acts evenly on the ice layer, reducing thermal stress caused by local overheating, reducing damage to the internal structure of the porcelain insulator, and extending the service life of the porcelain insulator.

[0019] IV. Adaptability to Complex Electromagnetic Environments and Cost Reduction: Electronic de-icing systems have high equipment requirements, complex technology, high costs, and are susceptible to electromagnetic interference. This system mainly relies on mechanical structures and thermal methods for de-icing, without depending on electronic means such as high-frequency electric fields or pulsed currents. Therefore, it is unaffected by electromagnetic environments and can operate stably in various complex electromagnetic environments. Moreover, the overall technology is relatively simple, and the equipment cost is lower, reducing the cost investment in de-icing porcelain insulators.

[0020] V. Combination of Telescopic Components and Ice Crushing Mechanism: The first, second, and third telescopic components are all driven by servo motors and electric cylinders. This combination makes the adjustment of the entire de-icing device more precise and flexible. Through the precise control of the electric cylinders, the positions of the clamping arc plate and the ice crushing mechanism can be quickly and accurately adjusted, enabling effective removal of ice layers of different locations and shapes, thus improving the adaptability and accuracy of the de-icing operation.

[0021] VI. Combination of Heating, Ice Crushing, and Hot Gas Assistance: The system employs a combination of three methods: electric heating grid heating, ice crushing, and hot gas-assisted heating. The electric heating grid first heats and melts the ice layer, reducing its hardness; then, the ice crushing blocks break up the softened ice, accelerating its removal; and the hot gas assists in the heating process, improving thermal efficiency and ensuring more even heating of the ice layer, further enhancing the de-icing effect. This synergistic combination of multiple methods is key to the system's high de-icing efficiency.

[0022] VII. Combination of Dustproof Net and Air Supply Component: Dustproof nets are installed at the air inlet and hot air nozzle outlet of the air supply component. This ensures normal air intake and hot air output while effectively preventing dust and other impurities from entering the airflow channel and adhering to the insulator surface. Dust entry can affect the heating efficiency of the electric heating network and the unobstructed flow of hot air nozzles. The dustproof nets ensure the stable operation and effective de-icing of the de-icing system, while also reducing dust contamination of the insulators, thus helping to maintain their electrical performance.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figures 1 to 3 As shown, a porcelain insulator de-icing system includes a drone platform 1. A horizontally positioned first telescopic component 2 is mounted on the drone platform 1. A mounting base 3 is fixedly connected to the movable part of the first telescopic component 2. Clamping arc plates 402 are fixedly connected to both sides of the mounting base 3 via horizontally positioned second telescopic components 401. A heating groove is provided on the side of the clamping arc plate 402 facing the insulator. The heating groove is adapted to a partial side of the insulator. An electric heating mesh 403 is provided on the inner wall of the heating groove. A closed heat-conducting layer 404 is provided on the outer surface of the electric heating mesh 403. A horizontally positioned ice-crushing mechanism is provided on the side of the mounting base 3 facing the insulator. The ice-crushing mechanism includes a third telescopic component 501 connected to the mounting base 3. Ice blocks 503 are connected to the movable part of the third telescopic component 501 via a spring telescopic rod 502.

[0030] like Figures 1 to 3 As shown, utilizing the flexible flight capabilities of the UAV platform 1, the de-icing device it carries is quickly transported to the vicinity of the porcelain insulator requiring de-icing. Through the UAV's own attitude adjustment and flight control, the de-icing device is brought as close as possible to the target porcelain insulator, preparing for subsequent precise de-icing operations. The first telescopic component 2 begins to operate, its movable part driving the mounting base 3 to move laterally, adjusting the horizontal position of the mounting base 3. When the mounting base 3 has roughly reached the appropriate position, the second telescopic component 401 activates, pushing the clamping arc plates 402 on both sides towards the center, so that the heating grooves on the clamping arc plates 402 are tightly fitted with the local side of the porcelain insulator. Because the heating grooves are adapted to the local side of the insulator, this fit ensures that the de-icing device is stably fixed to the insulator during operation, providing stable support for subsequent heating and ice-breaking operations.

[0031] The electric heating mesh 403 installed on the inner wall of the heating tank begins to heat up after being energized. The heat generated by the electric heating mesh 403 is evenly transferred to the ice layer in contact with the heating tank through the sealed heat-conducting layer 404 on its outer surface. The sealed heat-conducting layer 404 not only conducts heat efficiently but also provides a certain degree of insulation and protection, preventing excessive heat loss and avoiding potential short circuits caused by direct contact between the electric heating mesh 403 and the ice layer. As heat continues to be transferred, the ice layer gradually absorbs heat and begins to melt, reducing its hardness and creating conditions for subsequent ice-breaking operations.

[0032] While the electric heating network 403 is heating, the third telescopic component 501 is activated, and its moving part drives the spring telescopic rod 502 and the ice crushed block 503 to move laterally. During this movement, the ice crushed block 503 comes into contact with the softened ice layer. Due to the elasticity of the spring telescopic rod 502, when the ice crushed block 503 impacts the ice layer, it can automatically adjust the impact force according to the hardness and thickness of the ice layer, avoiding damage to the porcelain insulator due to excessive impact force, while effectively breaking the ice layer. The broken ice layer, under the action of gravity and subsequent possible airflow (if there is relevant airflow auxiliary design), falls off the surface of the porcelain insulator, thus achieving the purpose of de-icing.

[0033] Based on the above-described operating principle, this porcelain insulator de-icing system can achieve efficient, safe, and precise de-icing operations. The use of the drone platform 1 allows the de-icing device to quickly reach any porcelain insulator requiring de-icing, making it particularly suitable for large groups of porcelain insulators or areas difficult to access manually, significantly improving the efficiency and coverage of de-icing operations. The tight fit between the clamping arc plate 402 and the porcelain insulator ensures stability during the de-icing process, preventing any impact on the de-icing effect due to device shaking. The combination of heating by the electric heating network 403 and crushing by ice blocks 503, first reducing the hardness of the ice layer through heating and then using ice blocks 503 for crushing, allows for faster and more thorough removal of the ice layer compared to single heating or mechanical crushing methods, while reducing the risk of damage to the porcelain insulators.

[0034] like Figures 1 to 3As shown, the first telescopic component 2, the second telescopic component 401, and the third telescopic component 501 are all configured as electric cylinders driven by servo motors. The electric cylinder is a modular product integrating the servo motor and the lead screw, converting the rotational motion of the servo motor into linear motion. When the servo motor starts, its output shaft drives the lead screw to rotate, and the nut on the lead screw moves linearly along the lead screw. Since the moving part of the electric cylinder is connected to the nut, the linear movement of the nut drives the moving part of the electric cylinder to telescopically extend and retract. This method of converting rotational motion into linear motion has advantages such as compact structure, high transmission efficiency, and smooth movement, making it very suitable for use in scenarios requiring precise linear motion, such as de-icing of porcelain insulators. The first, second, and third telescopic components 501 enable this porcelain insulator de-icing system to achieve highly precise and controllable de-icing operations. The high-precision control capability of the servo motor allows each telescopic component to move accurately according to a preset program, ensuring the positioning accuracy of the mounting base 3, the clamping force of the clamping arc plate 402, and the impact effect of the ice-crushing mechanism. The linear motion characteristics of the electric cylinder ensure the smoothness and reliability of the extension and retraction process, reducing the impact of mechanical vibration on de-icing operations. Overall, this design improves the efficiency and quality of de-icing operations, effectively and safely removing ice from the surface of porcelain insulators and ensuring the stable operation of the power system.

[0035] The ice crusher 503 is designed in spherical, hemispherical, or conical shapes. By designing the ice crusher 503 in these three different shapes, the porcelain insulator de-icing system can flexibly select the appropriate ice crusher 503 for de-icing operations based on the actual thickness and hardness of the ice layer, thus significantly improving the efficiency and effectiveness of de-icing. For thinner and softer ice layers, using spherical ice crushers 503 can uniformly break the ice layer, avoiding unnecessary damage to the porcelain insulator; for ice layers of medium thickness and hardness, hemispherical ice crushers 503 can balance breaking effect and safety; and for thicker and harder ice layers, conical ice crushers 503 can exert their strong local breaking ability to quickly and effectively remove the ice layer. This diverse ice crusher 503 design allows the de-icing system to adapt to various complex ice layer conditions, ensuring the safe operation of porcelain insulators in severe weather.

[0036] like Figures 1 to 3As shown, the spring telescopic rod 502 includes a fixed tube fixedly connected to the third telescopic component 501. A movable rod is slidably connected to the inner wall of the fixed tube. The bottom of the movable rod is connected to the bottom of the fixed tube via a buffer spring, and one end of the movable rod is fixedly connected to the ice crush 503. Through this structural design of the spring telescopic rod 502, the porcelain insulator de-icing system can achieve buffering and adaptive adjustment of the ice crush 503 during the de-icing process. When impacting the ice layer, the buffer spring can effectively absorb the reaction force of the ice layer, avoiding damage to the device caused by rigid collisions and extending the service life of the de-icing device. Simultaneously, according to the hardness and thickness of the ice layer, the buffer spring can automatically adjust the impact force of the ice crush 503, enabling the ice crush 503 to break the ice layer with appropriate force, improving the efficiency and effect of de-icing. Furthermore, the fixed connection between the movable rod and the ice crush 503 ensures the accuracy of de-icing, ensuring that the ice crush 503 can accurately target and break the ice layer, providing a strong guarantee for the safe operation of the porcelain insulator.

[0037] like Figures 1 to 3 As shown, an airflow channel 603 is provided inside the clamping arc plate 402. An air supply component 601 is fixedly installed on the back of the clamping arc plate 402. The air outlet of the air supply component 601 is connected to the airflow channel 603. Multiple hot air nozzles 602 are evenly opened on the outside of the heating groove of the clamping arc plate 402. The hot air nozzles 602 are connected to the airflow channel 603. One side of the airflow channel 603 is the back of the electric heating grid 403. The airflow passes through the air supply component 601, the airflow channel 603, the electric heating grid 403 and the hot air nozzles 602 in sequence. The hot air nozzles 602 face the insulator direction.

[0038] The air supply component 601, acting as the source of the airflow, is responsible for generating and delivering airflow with a certain pressure and flow rate. When the air supply component 601 is activated, the airflow enters the airflow channel 603 inside the clamping arc plate 402, which is connected to it, through its outlet. The airflow channel 603 has a specific layout inside the clamping arc plate 402, providing a path for stable airflow and ensuring that the airflow can smoothly reach the subsequent heating and spraying stages. An electric heating grid 403 is located on one side of the airflow channel 603. When the airflow passes through the electric heating grid 403, the grid is energized and heats up, converting electrical energy into heat energy to heat the passing airflow. The electric heating grid 403 has high heating efficiency, capable of heating the airflow to a suitable temperature in a short time, turning it into hot air. This heating method can quickly increase the temperature of the airflow, providing sufficient heat for subsequent de-icing operations. Multiple hot air nozzles 602, evenly distributed on the outer side of the clamping arc plate 402, are connected to the airflow channel 603. Hot air, heated by the electric heating mesh 403, is sprayed towards the insulator through these nozzles 602. Because the hot air nozzles 602 are evenly distributed, the hot air can uniformly cover the insulator surface, subjecting the ice layer on the insulator surface to comprehensive heating. Upon contact with the ice layer, the hot air transfers heat to the ice layer, raising its temperature. When the ice layer reaches its melting point, it begins to melt, thus achieving the de-icing effect.

[0039] By implementing the above technical solution, the ice layer on the surface of the insulator can be heated and melted efficiently and uniformly. The air supply component 601 continuously provides a stable airflow, ensuring the supply of hot air; the electric heating network 403 rapidly heats the airflow, giving the hot air a sufficient temperature to melt the ice layer; the evenly distributed hot air nozzles 602 ensure that the hot air can fully cover the surface of the insulator, avoiding the problem of incomplete de-icing caused by uneven local heating. Compared with traditional mechanical de-icing methods, this hot air heating de-icing method has the advantages of less damage to the insulator, high de-icing efficiency, and simple operation, and can effectively ensure the normal operation of the insulator under harsh weather conditions.

[0040] like Figures 1 to 3As shown, the air supply component 601 is an electric air pump. Dust filters 604 are installed at the air inlet and the outlet of the hot air nozzle 602 of the air supply component 601. The electric air pump, as the air supply component 601, operates on the principle of using an electric motor to drive internal pistons or impellers to reciprocate or rotate, thereby creating a negative pressure inside the pump. This draws in outside air, which is then compressed and discharged from the outlet at a certain pressure and flow rate, providing a stable air source for subsequent airflow heating and injection. The dust filter 604 at the air inlet prevents dust, particles, and other impurities from entering the pump when it draws in outside air. If these impurities enter the pump, they may wear down internal components, affecting its normal operation and service life. A dustproof net 604 is installed at the outlet of the hot gas nozzle 602 to prevent external dust and other impurities from flowing back into components such as the airflow channel 603 and the electric heating net 403 after the hot gas stops spraying, thus avoiding these components from being blocked or contaminated by dust and ensuring the smooth and normal operation of the entire hot gas supply system.

[0041] The electric air pump provides a stable airflow, ensuring the continuity and stability of hot air injection and providing a reliable air source for insulator de-icing operations. The 604 dustproof mesh effectively reduces damage to the air pump and hot air supply system caused by dust and other impurities, extending the service life of the equipment, reducing maintenance costs, and ensuring the quality and effect of hot air injection, avoiding problems such as uneven hot air injection or reduced flow rate due to impurities clogging the system.

[0042] like Figures 1 to 3 As shown, the drone platform 1 has a landing gear 7 at its bottom for stable flight. The landing gear 7 is an important support and stabilizing component during drone flight. During takeoff and landing, the landing gear 7 contacts the ground, bears the weight of the drone, and provides stable support to prevent the drone from tipping over or being damaged due to instability during takeoff and landing. During drone flight, the landing gear 7 plays a certain role in balance and stability, especially when encountering air turbulence. The landing gear 7 increases the contact area between the drone and the air, and by adjusting its attitude and stress conditions, helps the drone maintain flight stability.

[0043] like Figures 1 to 3As shown, the outer surface of the sealed thermally conductive layer 404 is coated with an anti-slip coating to achieve efficient de-icing. The anti-slip coating serves two purposes: firstly, when a drone carrying de-icing equipment approaches the insulator for de-icing operations, the anti-slip coating increases the friction between the equipment and the insulator, preventing the equipment from slipping and failing to hold accurately upon contact, ensuring stable contact between the equipment and the insulator surface and improving de-icing efficiency. Secondly, during the de-icing process, some ice chips or water droplets may adhere to the surface of the equipment; the anti-slip coating prevents these ice chips or water droplets from making the surface smooth, further ensuring stable contact between the equipment and the insulator.

[0044] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
