Description

Technical Field

[0001] The invention relates to the technical field of power line deicing, and in particular to an electromagnetically driven power line deicing device. Background Art

[0002] Electromagnetically driven power line de-icing devices are often referred to as "electromagnetic de-icers" or "electromagnetic de-icing devices". They use the action of electromagnetic force to remove ice and snow from power lines to avoid line failure or breakage caused by ice and snow accumulation. By periodically powering on and off, mechanical vibrations can be generated in the power lines. This vibration can break the structure of the ice layer and cause the ice and snow to fall off the surface of the wires.

[0003] The patent with the patent publication number CN117996671A discloses a jet deicing device for power lines. The electric push rod drives the translation block to translate, so that the electric wheel one, the electric wheel two and the electric wheel three are close to the power line for extrusion deicing. The rubber sleeve covers the power line, and the jet pipe performs jet deicing on the power line to reduce residual crushed ice. After the deicing is completed, the electric push rod can be controlled to disassemble the device, and the installation is automated. It can also de-ice three power lines at the same time, with high deicing efficiency and good deicing effect.

[0004] The prior art has the following defects: Limited applicable environment: Devices equipped only with electromagnetic vibrations are usually effective under certain conditions, such as when the ice layer is thin or has not yet completely frozen. However, for thick ice layers or ice-snow mixtures formed in extreme weather, the electromagnetic-driven de-icing effect is not ideal. Ice-snow mixtures are usually composed of multi-layer structures, such as snow layers, freezing rain layers and ice layers. These different layers of materials respond differently to electromagnetic forces, making it difficult for a single electromagnetic drive to effectively clear all layers at once. Therefore, an auxiliary ice-cutting device is required to break up the thick ice layer and promote the effect of electromagnetic de-icing.

[0005] Lack of protection for power lines during de-icing: The electromagnetic de-icing device will generate induced current during operation. If the current is too large, it will interfere with the normal current transmission of the line, causing malfunction of the power equipment or signal transmission failure. Therefore, it is necessary to reduce the current as much as possible and use mechanical de-icing to assist. When using mechanical methods for de-icing, if the force is too large or the operation is improper, it will directly cause mechanical damage to the wires, insulators or other components of the power line, such as scratches, bending or even breakage. Therefore, it is necessary to set up a structure that maintains a constant distance from the power line so that the mechanical de-icing only acts on the ice layer to reduce damage to the power line.

[0006] Placing and removing the device is more troublesome: power lines are usually located at high altitudes, requiring special high-altitude working tools and technicians to operate, which increases the difficulty and risk of installation. Common methods for placing and removing de-icing devices include drone mounting method, manual climbing method, robotic arm installation method, suspended pulley method, etc. The manual climbing method is more dangerous, the robotic arm installation method is more affected by environmental conditions, and the fixing and maintenance of the pulley system in the suspended pulley method is more complicated. Therefore, the drone mounting method is more applicable, but the existing drone mounting method is relatively simple to place and more troublesome to remove. Therefore, it is necessary to set up a simplified structure for drones to simply remove the de-icing device to save construction time and improve efficiency. Summary of the invention

[0007] In view of the problems of the prior art such as limited applicable environment, lack of protection and placement of power lines during deicing, and troublesome removal of the device, an electromagnetically driven power line deicing device is proposed.

When the rotating column 31 extends into the docking column 35, it first contacts the limiting groove 36 and rotates due to the blocking of the limiting groove 36, and finally snaps into the clamping door 37. Then the rotating column 31 is rotated to fix it. When the clamping column 33 extends into the docking column 35, it also squeezes the positioning semi-ring 38. A signal sensor is provided at the bottom of the positioning semi-ring 38. When the bottom of the positioning semi-ring 38 contacts the power line, it is triggered, indicating that the power line is in the middle of the device housing 1.

In addition, the supporting spring 47 is provided to support and limit the rotating cylinder 46.

[0051] Then, the rotating column 31 at the bottom of the drone 2 is inserted into the docking column 35 on the docking horizontal plate 34, and the positioning half ring 38 is squeezed out of the docking column 35. The clamping column 33 contacts the limiting groove 36 and expands outward, and is clamped into the clamping doors 37 on both sides. Then, the rotating column 31 is rotated to make the clamping column 33 clamped into the groove of the L-shaped movable groove 32 to complete the docking.

[0052] Operate the drone 2 to move the device to the top of the middle section of the power line. The positioning semi-ring 38 at the bottom of the docking cross plate 34 contacts the power line and sends a signal. Rotate the rotating column 31 to disconnect the rotating column 31 from the docking column 35, and retract the drone 2. At the same time, the positioning semi-ring 38 is retracted into the docking column 35 by the rebound force of the contraction spring 39. At the same time, start the rotating cylinder 46 to rotate the ice-breaking bracket 51 in the device housing 1 by 90° and place the ice-breaking bracket 51 below the power line.

[0053] During de-icing, the servo motor 52 is operated in the de-icing direction, and the servo motor 52 drives the ice cutting wheel 551 to rotate through the transmission shaft 53. At this time, the ice cone breaking baffle 54 first contacts the ice cone and breaks the ice cone, and then the anti-skid wheel plate 552 contacts the ice layer under the power line and is squeezed and compressed into the embedding groove 555. The ice cutting plate 553 leaks out of the ice cutting groove 554 to cut the ice layer. The anti-skid wheel plate 552 contacts the ice layer in turn and cuts the ice layer as it rotates, so that the ice layer breaks. The anti-skid wheel plate 552 that is not in contact with the ice layer is reset under the rebound of the compressed spring 556. After the ice layer breaks, the electromagnetic vibrators 6 on both sides of the ice layer perform electromagnetic de-icing operations.

[0054] The power line is in a curved shape between the power towers. When the de-icing device climbs or descends on the power line, the auxiliary running wheel 41 will move in the vertical movable groove 43 with the ups and downs of the power line, and drive the ice cutting wheel 551 to move through the adjustment rod 452, so that the distance between the ice cutting wheel 551 and the auxiliary running wheel 41 is always constant, avoiding the situation where the ice layer is not cut or the ice is cut too deep, reducing damage to the power line and improving the de-icing efficiency.

[0055] After the de-icing of the power line in one direction is completed, the device is operated in the reverse direction to perform secondary de-icing, and the power line in the other direction is de-iced. Finally, the device returns to the middle section of the power line, and the drone 2 is used to remove the device through the docking component 3 to complete the operation.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
