Embodiment 1

[0032] Such as Figure 1 to Figure 7 As shown, a power cable deicing device includes a running mechanism and a frame 2 connected below the running mechanism through a mechanical arm 1. The road wheels 4 and the front road wheels 5 that are stuck on the ice-covered part of the power line 3 are not removed. The frame 2 is provided with a deicing mechanism, and the deicing mechanism is located between the rear road wheels 4 and the front road. Between the wheels 5, a wireless controller 6 is installed on the left side inside the frame 2, and the traveling mechanism is connected to the wireless controller 6 by electrical signals; the deicing mechanism includes an ice-coated crushing module 7 from left to right , Waterjet segmentation module 8 and pre-cutting module 9.

[0033] The ice-coated crushing module 7 includes a crushing module bracket 10 arranged on the frame 2, a semi-frame-shaped fixed jaw 11 with an opening on the left side of the upper end of the crushing module brac...

Embodiment 2

[0041] Such as Figure 8 As shown, the difference between it and Embodiment 1 is that: the top of the water tank 25 is provided with an opening, the opening is provided with a funnel 41 for receiving ice and snow, and the top of the frame 2 is provided with a gap corresponding to the position of the funnel 41 for receiving ice and snow 42 is used to install a heating module 43 at the bottom of the water tank 25 and the heating module 43 is electrically connected to the wireless controller 6 .

[0042] In this embodiment, an opening is set on the top of the water tank, and an ice and snow funnel is arranged on the opening, and a gap is provided at the top of the frame corresponding to the position of the ice and snow funnel to collect ice cubes falling from the power line, and the bottom of the water tank Set up a heating module and connect the heating module to the wireless controller with electrical signals, so that during the deicing process, some falling ice cubes can be co...

Embodiment 3

[0044] Such as Figure 9 As shown, the difference between it and Embodiment 2 is that: the center of gravity adjustment module is arranged at the bottom of the frame 2, and the center of gravity adjustment module includes a counterweight 47 that is slidingly arranged at the bottom of the frame 2 using a dovetail structure and is arranged on the bottom of the frame 2. The automatic telescopic rod 48 on the left side of the bottom of the frame 2, the free end of the automatic telescopic rod 48 is connected with the counterweight 47, and the automatic telescopic rod 48 is connected with the wireless controller 6 by electrical signals.

[0045] The automatic telescopic rod 48 is an electric telescopic rod.

[0046] In this embodiment, a center-of-gravity adjustment module is provided at the bottom of the frame to adjust the center of gravity of the device, so as to avoid the instability of the center of gravity from affecting the work of the device; The position of the block can ...

Abstract

The invention discloses a power cable deicing device. The power cable deicing device comprises a travel mechanism and a frame which is connected with the lower side of the travel mechanism through a robot arm. The travel mechanism comprises a rear travel wheel which is arranged at a part without icing on a power cable, and a front travel wheel which is arranged at a part with icing on the power cable. A deicing mechanism is arranged on the frame. The deicing mechanism is located between the rear travel wheel and the front travel wheel. A wireless controller is arranged on the left side of in the frame. The travel mechanism is in electrical signal connection with the wireless controller. The deicing mechanism comprises an icing breaking module, a water jet cutting module and a pre-cutting module in order from left to right. The water pressure of the water jet cutting module is adjusted according to the detected thickness of an icing layer. When icing on the surface is cut, deicing is efficiently carried out without the influence of the thickness of the icing layer, and a line is prevented from being damaged. The pre-cutting module is used to pre-cut the icing, and the icing is easily divided into small pieces when water jet cutting is carried out.

Description

technical field [0001] The invention belongs to the technical field of electric power maintenance, and in particular relates to a power cable deicing device. Background technique [0002] Faults caused by icing of power lines have always been one of the serious disasters in power systems at home and abroad. Internationally, the research on line icing is also very important. The International Large Power Grid Conference has organized experts from various countries to conduct special discussions. The International Electrotechnical Commission has specially formulated technical standards on power line icing. Northwest China and Northeast China are cold in winter, and high-voltage transmission lines are seriously icing. Although the anti-icing technology is used to suppress the formation and development of icing to a certain extent, avoiding or reducing accidents caused by icing, its potential hazards have always troubled Power sector. Some major ice disasters that have occurre...
