Description

Technical Field

[0001] This invention relates to the field of snow removal devices for power transmission lines, specifically a power transmission line anti-icing device based on unmanned aerial vehicles (UAVs). Background Technology

[0002] In extreme weather conditions, snow and ice accumulation can increase the weight of overhead power lines, causing them to bear excessive loads. This can lead to power line breakage or the downing of power poles, resulting in power outages. Therefore, it is necessary to remove ice from the cable surface to prevent damage to the lines and power outages.

The connecting frame contains a fixed frame, a first connecting arm, and a second connecting arm. Rollers are connected to opposite sides of both the first and second connecting arms. A drive telescopic push rod is connected to the lower end of the fixed frame. Two inclined plates are connected to the lower end of the drive telescopic push rod. Elimination components are provided at opposite ends of the two inclined plates. The two elimination components are slidably connected to the first and second connecting arms, respectively. Vertical grooves are provided on both the first and second connecting arms, and the elimination components are slidably connected to the vertical grooves. Each elimination component includes an upper arc-shaped cleaning block. A lower arc-shaped cleaning block is hinged to the lower end of the upper arc-shaped cleaning block via a hinge shaft. An elastic spring is provided on one side of the hinge shaft. The lower ends of the two lower arc-shaped cleaning blocks are connected to the two inclined plates via a third connecting arm, respectively. A heating plate is connected to the lower end of the two inclined plates. Impact rods are evenly spaced on the lower surface of the heating plate.

[0004] This device facilitates the removal of ice and snow from power transmission lines, improving work efficiency. However, it is troublesome to disassemble and maintain, and it is difficult to guarantee the stability of the equipment during operation, which leads to low work efficiency. Therefore, a UAV-based anti-icing device for power transmission lines is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to solve the problems mentioned in the background art, and thus proposes a UAV-based anti-icing device for power transmission lines. This invention utilizes the coordinated operation of a connecting plate, a first fixing plate, a motor, a second fixing plate, a rotating rod, a first gear, a second gear, a pulley, a rotating device, a locking shaft, a locking plate, a bracket, a movable hook lock, and a mounting mechanism. During installation, a UAV is used to hook up the movable hook lock, and then the UAV suspends the mounting mechanism onto the power line. This allows the device to be suspended to different positions by the UAV, further improving its adaptability to the external working environment. It also makes maintenance faster for workers, saving installation time. When the device needs to be disassembled, the UAV can directly remove the mounting mechanism from the power line, making device replacement quicker and more convenient, rapidly responding to emergency snow removal needs, and minimizing the impact of disasters on the power system. By setting up the mounting mechanism, multiple sets of internal limit wheels work together to ensure the device is securely attached to the cable and facilitates installation and removal from the cable.

[0006] The technical solution adopted by this invention to solve its technical problem is: A drone-based anti-icing device for power transmission lines includes a connecting plate. A first fixing plate is fixedly connected to the bottom of the connecting plate. A motor is fixedly connected to the rear side of the first fixing plate, and a gear is fixedly connected to the output end of the motor. A second fixing plate is fixedly connected to the bottom of the connecting plate. A rotating rod is rotatably connected to the inner wall of the second fixing plate, and a gear is fixedly connected to the circumferential surface of the rotating rod. A pulley is fixedly connected to the rear end of the rotating rod, and a rotating device is installed at the rear end of the pulley. A locking shaft is fixedly connected to the rear end of the pulley. A locking plate is installed at the bottom of the connecting plate, and a bracket is fixedly connected to the bottom of the connecting plate. A mounting mechanism is fixedly connected to the top of the connecting plate, and a movable hook is fixedly connected to the top of the mounting mechanism. Cables pass through the mounting mechanism. During installation, a drone is used to hook the movable hook, and the drone then suspends the mounting mechanism onto the power line. This allows the device to be suspended at different locations by the drone during use, further improving performance. The heightened equipment allows for better adaptation to the external working environment, while also enabling faster maintenance by staff and saving installation time. The mounting mechanism includes a C-shaped outer frame, with a movable hook lock installed on the top surface of the C-shaped outer frame. An inner C-shaped frame is installed inside the outer frame, and two sets of side supports are installed within the inner frame. These side supports are rotatably mounted within the inner frame via a pivot. Two sets of limiting wheels are fixedly installed at the upper and lower ends of the inner side of each side support. An A-shaped frame is installed within each of the two sets of side supports, with four sets of upper limiting wheels contacting the top surface of the A-shaped frame. Two sets of limiting wheels are installed on the left and right sides of the bottom surface of the A-shaped frame. A telescopic rod is installed on the top surface of the A-shaped frame, with its top end passing through and securing the inner and outer C-shaped frames. When the equipment needs to be disassembled, the mounting mechanism can be directly removed from the power line using a drone, making equipment replacement quicker and more convenient, rapidly responding to emergency snow removal needs, and minimizing the impact of disasters on the power system.

[0007] Preferably, the circumferential surface of the bracket is provided with a shaking mechanism to assist in snow removal, and the circumferential surface of the bracket is provided with an antifreeze mechanism to prevent the equipment from freezing.

[0008] Preferably, the front side of the second fixing plate is fixedly connected to the motor, the first gear meshes with the second gear, the pulley is rotatably connected to the end of the rotating rod, the circumferential surface of the snap-fit ​​shaft contacts the rotating device, and the snap-fit ​​plate contacts the top of the rotating device.

[0009] Preferably, the shaking mechanism includes a counterweight, and a rotating plate is rotatably connected to the top of the counterweight. During operation, the pulley will drive the rotating plate through the belt to clear the snow, preventing the conductor from swinging or shifting due to the imbalance of the counterweight, reducing the risk of phase-to-phase short circuits and discharge to ground, and improving the stability during operation. A second positioning block is fixedly connected to the top of the rotating plate, and a telescopic hinge rod is rotatably connected to the inner wall of the second positioning block. A first positioning block is fixedly connected to the bottom of the connecting plate.

Rollers are fixedly connected to both ends of the reciprocating screw, and a scraper is movably connected to the circumferential surface of the reciprocating screw. When the rotating plate flips, the rotation of the rotating plate drives the scraper to move back and forth to scrape the snow on the rotating plate, which further improves the cleaning effect on the rotating plate, makes the operation of the equipment more stable, reduces the failure rate of the equipment, and improves the service life of the equipment.

[0011] Preferably, the circumferential surface of the bracket is slidably connected to the inner wall of the counterweight, the inner wall of the positioning block is hinged to the telescopic hinge rod, the circumferential surface of the roller is in contact with the arc rod, and the bottom of the scraper is in contact with the top of the rotating plate.

[0012] Preferably, the antifreeze mechanism includes a movable plate, the inner wall of which is slidably connected to a striking block via a spring. While cleaning the hammer, the scraper moves, causing the striking block to strike the surface of the hammer, shaking off the accumulated snow and preventing surface icing during cleaning. This further improves the stability of the equipment, making cleaning of power transmission lines faster and increasing overall equipment efficiency. A protrusion is fixedly connected to the top of the rotating plate, and an antifreeze box is fixedly connected to the circumference of the support. A rotating plate is rotatably connected to the inner wall of the antifreeze box via a torsion spring.

A round rod is fixedly connected to the rear end of the pulley. During snow removal, the pulley rotates, causing the rotating plate to flip, and the antifreeze in the antifreeze box flows out intermittently, providing indirect antifreeze protection for the support. This avoids waste of antifreeze, improves the stability of the equipment during operation, prevents the equipment from jamming at low temperatures, and extends the equipment's service life.

[0013] Preferably, the outer surface of the scraper is fixedly connected to the moving plate, the bottom of the striking block is in contact with the rotating plate, the inner wall of the liquid outlet device is in contact with the circumferential surface of the support, the top of the L-shaped rod is in contact with the bottom of the rotating plate, and the bottom of the L-shaped rod is in contact with the circumferential surface of the round rod.

This invention utilizes the coordinated operation of a connecting plate, a first fixing plate, a motor, a second fixing plate, a rotating rod, a first gear, a second gear, a pulley, a rotating device, a snap-fit ​​shaft, a snap-fit ​​plate, a bracket, a movable hook lock, and a mounting mechanism. During installation, a drone is used to hook the movable hook lock, and then the drone suspends the mounting mechanism onto the power line. This allows the device to be suspended in different positions by the drone, further improving its adaptability to the external working environment. It also makes maintenance faster for workers, saving installation time. When the device needs to be disassembled, the drone can directly remove the mounting mechanism from the power line, making device replacement quicker and more convenient. This allows for rapid response to emergency snow removal needs, minimizing the impact of disasters on the power system. The mounting mechanism, with multiple sets of internal limit wheels working together, ensures the device is securely attached to the cable and facilitates easy installation and removal from the cable.

[0015] 2. This invention utilizes the coordinated operation of the counterweight, rotating plate, positioning block one, telescopic hinge rod, and positioning block two. During operation, the pulley drives the rotating plate to clear the snow, preventing the conductor from swaying or shifting due to the imbalance of the counterweight, reducing the risk of phase-to-phase short circuits and ground discharge, and improving the stability during operation.

[0016] 3. This invention utilizes the coordinated operation of the arc rod, roller, reciprocating screw, and scraper to clean the snow accumulated on the rotating plate as it flips. This further improves the cleaning effect on the rotating plate, making the equipment more stable, reducing the failure rate, and extending the service life of the equipment.

[0017] 4. This invention utilizes the coordinated operation of the moving plate, the striking block, and the protrusion. While cleaning the heavy hammer, the moving scraper drives the striking block to strike the surface of the heavy hammer, which can shake off the snow on the surface and prevent the surface from freezing during cleaning. This further improves the working stability of the equipment, makes cleaning power transmission lines faster, and increases the overall working efficiency of the equipment.

[0018] 5. This invention utilizes the coordinated operation of the antifreeze box, rotating plate, liquid outlet device, L-shaped rod, and round rod.

[0021] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0022] like Figures 1-10As shown, a UAV-based anti-icing device for power transmission lines includes a connecting plate 1. A fixing plate 2 is fixedly connected to the bottom of the connecting plate 1. A motor 3 is fixedly connected to the rear side of the fixing plate 2. A gear 6 is fixedly connected to the output end of the motor 3. A second fixing plate 4 is fixedly connected to the bottom of the connecting plate 1. A rotating rod 5 is rotatably connected to the inner wall of the second fixing plate 4. A gear 7 is fixedly connected to the circumferential surface of the rotating rod 5. A pulley 10 is fixedly connected to the rear end of the rotating rod 5. A rotating device 11 is installed at the rear end of the pulley 10. A snap-fit ​​shaft 12 is fixedly connected to the rear end of the pulley 10. A snap-fit ​​plate 13 is installed at the bottom of the connecting plate 1. A bracket 14 is fixedly connected to the bottom of the connecting plate 1. A mounting mechanism 16 is fixedly connected to the top of the connecting plate 1. A movable hook lock 15 is fixedly connected to the top of the mounting mechanism 16. A cable 17 passes through the mounting mechanism 16. During installation, a drone is used to hook up the movable hook lock 15 and then use the drone to install and suspend the mounting mechanism 16 onto the line. This allows the device to be suspended to different positions by the drone during use, further improving the device's adaptability to the external working environment. It also makes it easier for staff to maintain the device and saves installation time. The mounting mechanism 16 includes a C-shaped outer frame 161, a movable hook lock 15 disposed on the top surface of the C-shaped outer frame 161, a C-shaped inner frame 162 disposed inside the C-shaped outer frame 161, two sets of side supports 163 disposed inside the C-shaped inner frame 162, the two sets of side supports 163 being rotatably disposed inside the C-shaped inner frame 162 via a rotating shaft 164, two sets of limiting wheel sets 165 being fixedly disposed at the upper and lower ends of the inner side of the side supports 163, an A-shaped frame 166 disposed inside the two sets of side supports 163, four sets of upper limiting wheel sets 165 respectively contacting the top surface of the A-shaped frame 166, and two sets of limiting wheels 165 being disposed on the left and right sides of the bottom surface of the A-shaped frame 166. The device has a wheel assembly 165. A telescopic rod 167 is provided on the top surface of the A-frame 166. The top end of the telescopic rod 167 passes through and fixes the inner C-frame 162 and the outer C-frame 161. When the device is attached to the cable 17, the cable 17 first contacts the limiting wheel assembly 165 below the A-frame 166. Under the action of the device's own weight, the cable 17 and the A-frame 166 move upward, the telescopic rod 167 retracts, and the A-frame 166 moves upward while driving the side support 163 to rotate around the pivot 164. The limiting wheel assembly 165 below the side support 163 is located below the cable 17, and at the same time clamps and lifts the cable 17, so that the device is stably installed on the cable 17.

[0023] like Figure 1 , Figure 3 and Figure 4As shown, the circumferential surface of the bracket 14 is provided with a swaying mechanism 8 for assisting snow removal, and the circumferential surface of the bracket 14 is provided with an antifreeze mechanism 9 to prevent the equipment from freezing. The front side of the second fixing plate 4 is fixedly connected to the motor 3, the first gear 6 meshes with the second gear 7, the pulley 10 is rotatably connected to the end of the rotating rod 5, the circumferential surface of the snap-fit ​​shaft 12 contacts the rotating device 11, and the snap-fit ​​plate 13 contacts the top of the rotating device 11. When the equipment needs to be disassembled, the mounting mechanism 16 can be directly removed from the line by a drone, making equipment replacement faster and more convenient, quickly responding to emergency snow removal needs, and minimizing the impact of disasters on the power system.

[0024] like Figure 6 and Figure 7 As shown, the shaking mechanism 8 includes a weight 81, a rotating plate 82 rotatably connected to the top of the weight 81, a positioning block 85 fixedly connected to the top of the rotating plate 82, a telescopic hinge rod 84 rotatably connected to the inner wall of the positioning block 85, and a positioning block 83 fixedly connected to the bottom of the connecting plate 1. During operation, the starting motor 3 drives gear 6 to rotate. The rotation of gear 6 drives gear 7 to rotate via its circumferential surface. The rotation of gear 7 drives pulley 10 to rotate, and pulley 10 drives the weight 81 to move via a belt. The movement of the weight 81 drives the rotating plate 83 to rotate. The movement of the movable plate 82 will drive the positioning block 85 to move. The movement of the positioning block 85 will drive the telescopic hinge rod 84 to move through the hinge point. The movement of the telescopic hinge rod 84 will drive the rotating plate 82 to rotate through the positioning block 83 at the bottom of the connecting plate 1, thus turning over the snow on the surface. After turning over, the rotating plate 82 will be reset by rising, which will facilitate the next use and avoid working failures caused by snow residue when working in snowy weather. It will also prevent the conductor from swinging or deviating due to the imbalance of the counterweight 81, reduce the risk of phase-to-phase short circuits and discharge to ground, and improve the stability during operation.

[0025] An arc rod 86 is fixedly connected to the top of the hammer 81, and a reciprocating screw 88 is rotatably connected to the top of the rotating plate 82. Rollers 87 are fixedly connected to both ends of the reciprocating screw 88, and a scraper 89 is movably connected to the circumferential surface of the reciprocating screw 88. When the rotating plate 82 flips, the rotation of the rotating plate 82 drives the reciprocating screw 88 to rotate, which in turn drives the rollers 87 to rotate. When the rollers 87 rotate, they come into contact with the arc rod 86, thereby causing the rollers 87 to rotate on their own axis. The rotation of the rollers 87 drives the reciprocating screw 88 to rotate. The rotation of the reciprocating screw 88 drives the scraper 89 to move back and forth through the reciprocating groove to scrape the snow on the rotating plate 82, further improving the cleaning effect on the rotating plate 82, making the equipment work more stably, reducing the equipment failure rate, and increasing the service life of the equipment.

[0026] The circumferential surface of the bracket 14 is slidably connected to the inner wall of the counterweight 81, the inner wall of the positioning block 83 is hinged to the telescopic hinge rod 84, the circumferential surface of the roller 87 is in contact with the arc rod 86, and the bottom of the scraper 89 is in contact with the top of the rotating plate 82.

[0027] Working principle: After snowfall in winter, snow accumulates on power transmission lines. A drone is used to install and suspend the mounting mechanism 16 onto the line. During use, the drone can suspend it in different positions, further improving the equipment's adaptability to the external working environment. This also makes maintenance faster and saves installation time. While reinforcing the equipment, when the equipment needs to be disassembled, the drone can directly remove the mounting mechanism 16 from the line, making equipment replacement quicker and more convenient. This allows for rapid response to emergency snow removal needs and minimizes the impact of disasters on the power system. When the device is attached to the cable 17, the cable 17 first contacts the limiting wheel group 165 below the A-frame 166. Under the action of the device's own weight, the cable 17 and the A-frame 166 move upward, the telescopic rod 167 retracts, and the A-frame 166 moves upward, driving the side bracket 163 to rotate around the pivot 164. The limiting wheel group 165 below the side bracket 163 is located below the cable 17, clamping and supporting the cable 17, so that the device is stably installed on the cable 17.

[0028] During operation, starting motor 3 drives gear 6 to rotate, which in turn drives gear 7 to rotate. Gear 7 rotates pulley 10, which in turn drives counterweight 81 via a belt. The movement of counterweight 81 moves rotating plate 82, which in turn moves positioning block 85. Positioning block 85 moves telescopic hinge rod 84 via hinge point, which in turn moves rotating plate 82 via positioning block 83 at the bottom of connecting plate 1, thus turning over the snow on the surface. After turning over the snow, rotating plate 82 is then reset by rising, making it easy to use next time and preventing work malfunctions caused by snow residue. The system prevents the conductor from swaying or shifting due to the imbalance of the counterweight 81, reducing the risk of phase-to-phase short circuits and ground discharge, and improving operational stability. When the rotating plate 82 flips, the rotation of the rotating plate 82 drives the reciprocating screw 88 to rotate, which in turn drives the roller 87 to rotate. When the roller 87 rotates, it contacts the arc rod 86, thereby causing the roller 87 to rotate on its own axis. The rotation of the roller 87 drives the reciprocating screw 88 to rotate, and the rotation of the reciprocating screw 88 drives the scraper 89 to move back and forth through the reciprocating slide groove to scrape the snow on the rotating plate 82, further improving the cleaning effect of the rotating plate 82, making the equipment work more stably, reducing the equipment failure rate, and increasing the service life of the equipment.

[0029] like Figures 1-10As shown, in another embodiment of the present invention, based on the above embodiments, the antifreeze mechanism 9 includes a movable plate 91. A striking block 92 is slidably connected to the inner wall of the movable plate 91 via a spring. A protrusion 93 is fixedly connected to the top of the rotating plate 82. While cleaning the hammer 81, the scraper 89 moves, driving the movable plate 91 to move. The movement of the movable plate 91 drives the striking block 92 to move. Simultaneously, the striking block 92 moves by contacting the top of the protrusion 93 with its bottom. After leaving the protrusion 93, the striking block 92 is reset by the spring, thereby striking the surface of the hammer 81. This shakes off the accumulated snow, preventing surface icing during cleaning, further improving the stability of the equipment, making cleaning of power transmission lines faster, and improving the overall efficiency of the equipment. The circumferential surface of the bracket 14 is fixed... An antifreeze box 94 is fixedly connected to the support frame 14. A rotating plate 95 is rotatably connected to the inner wall of the antifreeze box 94 via a torsion spring. A liquid outlet device 96 is installed at the bottom of the antifreeze box 94. An L-shaped rod 97 is slidably connected to the inner wall of the antifreeze box 94 via a torsion spring. A round rod 98 is fixedly connected to the rear end of the pulley 10. During snow removal, the pulley 10 rotates, causing the round rod 98 to rotate. The rotation of the round rod 98 causes the L-shaped rod 97 to move. The movement of the L-shaped rod 97 causes the rotating plate 95 to rotate through the top contact surface. The rotating plate 95 flips open, and antifreeze drips through the liquid outlet device 96, thus preventing the support frame 14 from freezing. When the round rod 98 is removed, the rotating plate 95 returns to its original position via the torsion spring. This achieves indirect antifreeze protection for the support frame 14, avoiding waste of antifreeze, improving the stability of the equipment during operation, preventing the equipment from jamming at low temperatures, and extending the service life of the equipment.

[0030] The outer surface of the scraper 89 is fixedly connected to the moving plate 91, the bottom of the striking block 92 is in contact with the rotating plate 82, the inner wall of the liquid outlet device 96 is in contact with the circumferential surface of the bracket 14, the top of the L-shaped rod 97 is in contact with the bottom of the rotating plate 95, and the bottom of the L-shaped rod 97 is in contact with the circumferential surface of the round rod 98.

[0031] Working Principle: While cleaning the hammer 81, the scraper 89 moves, driving the moving plate 91 to move. The moving plate 91 then moves the striking block 92. As the striking block 92 moves, it contacts the top of the protrusion 93 at its bottom, causing the striking block 92 to move as well. After leaving the protrusion 93, the striking block 92 is reset by a spring, thus striking the surface of the hammer 81. This shakes off the accumulated snow, preventing surface icing during cleaning and further improving the stability of the equipment. This makes cleaning power transmission lines faster and improves the overall working efficiency of the equipment. With improved efficiency, while removing snow, the pulley 10 rotates, driving the round rod 98 to rotate. The rotation of the round rod 98 drives the L-shaped rod 97 to move. The movement of the L-shaped rod 97 drives the rotating plate 95 to rotate through the top contact surface. The rotating plate 95 opens, and antifreeze drips through the liquid outlet device 96, thus preventing the bracket 14 from freezing. When the round rod 98 moves away, the rotating plate 95 will be reset by the torsion spring, thereby achieving indirect antifreeze protection for the bracket 14, avoiding waste of antifreeze, improving the stability of the equipment during operation, preventing the equipment from jamming when operating at low temperatures, and extending the service life of the equipment.
