Description

Technical Field

[0001] The present invention relates to the technical field of de-icing devices, and in particular to a cable de-icing device and method. Background Art

[0002] In a wet and cold environment, cables will frost and ice up. When the weight of the ice and frost exceeds the bearing capacity of the cable or the cable support structure, it will cause damage to the cable or collapse of the support structure; there are existing devices that combine multi-rotor drones for de-icing, such as the power distribution transmission line maintenance device disclosed in the patent with the application number 202223016775.7.

[0003] When the de-icing device de-ices, it needs to hold the cable to be de-iced tightly; the main lift of a multi-rotor drone comes from the rotation of multiple propellers, and the lift direction is always perpendicular to the fuselage plane (i.e., perpendicular to the propeller rotation plane); when in a hovering state, the total lift generated by multiple propellers is equal to the gravity, and the direction is vertically upward. At this time, the drone remains horizontal and has no translational movement; when in translational movement, to make the drone move in a certain direction, the fuselage must be actively tilted to deflect the lift direction so that it generates a horizontal component force to push the drone to move; this results in the de-icing device being unable to move when in a tightened state. Each time it moves, the cable must be released, and then tightened again after moving, which requires frequent loosening and tightening of the cable, with complex operations and low efficiency. Summary of the Invention

[0004] The main purpose of the present invention is to provide a cable de-icing device and method to solve the problem in the above-mentioned prior art that the de-icing device cannot move when in a tightened state, and each time it moves, the cable must be released and then tightened again after moving, which requires frequent loosening and tightening of the cable, with complex operations and low efficiency.

[0005] To achieve the above purpose, the present invention provides a cable de-icing device, including a multi-rotor drone and two relatively arranged heating devices; each heating device is connected to the multi-rotor drone through two connecting frames; a bottom rod is provided at the bottom of the multi-rotor drone, and a first chute is provided on the bottom rod along the up and down direction; a second chute is provided on the heating device along the front and back direction; the connecting frame includes a steering gear joint, the top of the steering gear joint is fixedly connected with a first slider slidably connected to the first chute, and the bottom is rotatably connected with a second slider slidably connected to the second chute, and the steering gear joint can rotate back and forth relative to the second slider.

[0006] Furthermore, a convex block is fixedly provided at the top of the first slider, and a stop block for preventing the first slider from sliding out of the first chute is fixedly provided on the bottom rod; the second chute is a dovetail groove, and the second slider is a dovetail block.

[0007] Further, the rudder joint includes a first steering gear fixedly connected to the first slider. A first rod is fixedly connected to the output shaft of the first steering gear.

[0009] Further, a distance sensor is fixedly connected to the inner side of the heating plate housing.

[0010] The present invention also provides a method for removing ice from a cable. Using the above-mentioned cable ice removal device, it includes the following steps: S1.

Adjust the positions of the heating devices through the first steering gear and the second steering gear to make the heating devices hold the cable tightly; S3. Start the heating device to heat and remove ice; S4.
