Description

Technical Field

[0001] The present invention relates to the technical field of power line deicing equipment, and in particular to a method and device for deicing an overhead line. Background Art

[0002] In cold regions and areas with varying terrain and climate conditions, ice accumulation on overhead power lines poses a significant threat to the safe operation of power grids. Traditional de-icing technologies primarily include mechanical scraping, thermal de-icing, and manual de-icing. Manual de-icing is inefficient and carries a high risk of falling. Thermal de-icing also suffers from high energy consumption and slow response times. Mechanical vibration de-icing equipment generally adopts a fixed frequency mode and cannot adapt to the dynamic changes of different ice thicknesses. For example, the existing Chinese patent document with application number 201610413341.4 discloses a distribution network overhead line de-icing device, which specifically discloses an insulating rod and a shell arranged on the insulating rod, a drive shaft is provided in the shell, a de-icing shovel extending out of the shell and moving up and down is provided on the shell, an eccentric wheel is provided on the drive shaft to drive the de-icing shovel to move up and down, a de-icing guide line protection machine is provided on the shell, and the de-icing guide line protection mechanism includes a connecting rod provided on the shell and a rotating shaft provided at the free end of the connecting rod, a rotating drum is mounted on the rotating shaft, a roller is mounted on the rotating drum, a groove is provided on the circumference of the roller to match the frozen wire, and the rotating drum is connected to the drive shaft through a transmission mechanism. The de-icing mechanism works as follows: The operator, seated, pedals, which rotates the drive shaft, which in turn rotates the lower transmission rod, which in turn rotates the upper transmission rod, which in turn rotates the rotating drum, which in turn rotates the roller, thereby moving the device over the wire. The drive shaft rotates the eccentric, which in turn drives the de-icing blade up and down, knocking and removing ice. This ensures that the de-icing blade's up-and-down motion is the same each time, striking with the same force regardless of ice thickness. However, wires covered in thin ice may be subjected to excessive force, which can damage the wire surface during the de-icing process. Summary of the Invention

The overhead line deicing method of this embodiment is performed using an overhead line deicing device. The overhead line deicing device includes a configuration mechanism 1, a knocking lever 2, a cam 3, and a control module. The configuration mechanism 1 is used to be configured on the overhead line. The middle part of the knocking lever 2 is rotatably arranged on the configuration mechanism 1, and a torsion spring 4 is provided between the configuration mechanism 1 and the configuration mechanism 1. The cam 3 is rotatably arranged on the configuration mechanism 1 and is used to push the knocking lever 2 to swing. The rotation center of the cam 3 can be moved and adjusted relative to the rotation center of the knocking lever 2. The configuration mechanism 1 is provided with an ice thickness detection mechanism 5 for detecting the thickness of the ice layer on the overhead line, a first drive mechanism 6 for driving the cam 3 to rotate, and a second drive mechanism 7 for driving the cam 3 to move relative to the rotation center of the knocking lever 2. The ice thickness detection mechanism 5, the first drive mechanism 6, and the second drive mechanism 7 are all electrically connected to the control module. The overhead line deicing method includes the following steps: Y1. Place the configuration mechanism 1 on the overhead line; Y2. The control module calculates the required movement adjustment amount of the rotation center of the cam 3 based on the detection value of the ice thickness on the overhead line by the ice thickness detection mechanism 5, and controls the second driving mechanism 7 to operate so that the rotation center of the cam 3 moves to the corresponding position; Y3. The control module controls the first driving mechanism 6 to operate, causing the cam 3 to rotate, and the knocking lever 2 swings back and forth under the push of the cam 3 and the elastic force of the torsion spring 4 to knock the ice on the overhead line.

[0030] In this overhead line deicing method, on the one hand, the ice thickness detection mechanism 5 detects the thickness of the ice layer on the overhead line, and the control module calculates the required movement adjustment amount of the rotation center of the cam 3 based on the detection value of the ice thickness detection mechanism 5, and controls the second drive mechanism 7 to operate, so that the rotation center of the cam 3 moves to the corresponding position. At this position, the cam 3 pushes the knocking lever 2 to swing, and the swing angle of the knocking lever 2 will not be too large. In this way, the energy storage of the torsion spring 4 will not be too high, and after the knocking lever 2 is separated from the cam 3, the force of knocking the ice layer under the action of the torsion spring 4 will not be too large, so that the ice layer can be knocked off without damaging the surface of the overhead line. On the other hand, during the knocking process, the ice thickness detection mechanism 5 detects the thickness of the ice layer on the overhead line in real time, and the control module controls the operation of the second drive mechanism 7 in real time based on the detection value of the ice thickness detection mechanism 5, so that the rotation center of the cam 3 is always at a position where the knocking lever 2 will not damage the overhead line, thereby ensuring that the overhead line is not damaged during the entire deicing process.

The functional relationship can accurately adjust the position of the cam 3 to ensure that the position of the cam 3 will not cause the knocking lever 2 to damage the surface of the overhead line and can also knock off the ice.

[0034] Furthermore, in this embodiment, the cam 3 rotates one circle to make the knocking lever 2 swing back and forth once, and the swing angle of the knocking lever 2 is Displacement of cam 3's rotation center relative to point A Satisfies the functional relationship:
