Embodiment 1

[0032] Such as Figures 1 to 5 As shown, a power transmission cable ice and snow removal device includes a running mechanism and a frame 2 connected below the running mechanism through a mechanical arm 1. The rear traveling wheel 4 and the front traveling wheel 5 stuck on the ice-coated unremoved part on the transmission line 3, a deicing mechanism is arranged on the frame 2, and the deicing mechanism is located between the rear traveling wheel 4 and the described Between the front traveling wheels 5, a wireless controller 6 is arranged on the left side inside the frame 2, and the traveling mechanism is electrically connected to the wireless controller 6; Module 7 and water knife segmentation module 8; Said water knife segmentation module 8 comprises the water knife support 9 that is arranged on the said frame 2, two jet cutting heads 10 that are arranged on the described water knife support 9, are arranged on The water tank 11 inside the frame 2 and the high-pressure pump 12...

Embodiment 2

[0039] Such as Image 6 , Figure 7 with Figure 8 As shown, the difference between it and Embodiment 1 is that an ice hanging removal module is set on the frame 2, and the ice hanging removal module is located between the water knife segmentation module 8 and the front road wheel 5, so The ice hanging removal module includes a removal module support 29 arranged on the frame 2 , a removal motor 30 arranged on the upper part of the removal module support 29 and a removal member arranged on the output shaft of the removal motor 30 .

[0040] Described clearing part comprises the rod body 31 that is arranged on the output shaft of described removal motor 30, and blind hole 32 is set on the both ends of described rod body 31, and end cover 33 is threadedly connected with described rod body 31 two ends, on described end cover 33 A through hole 34 is provided at a position corresponding to the position of the blind hole 32 , a block 35 is slidably arranged in the blind hole 32 , a...

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 provided at the bottom of the frame 2, and the center of gravity adjustment module includes a counterweight 42 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 43 on the left side of the bottom of the frame 2, the free end of the automatic telescopic rod 43 is connected with the counterweight 42, and the automatic telescopic rod 43 is connected with the wireless controller 6 by electrical signals.

[0045] The automatic telescopic rod 43 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 an ice and snow removing apparatus for a power transmission line. The ice and snow removing apparatus comprises a walking mechanism and a rack connected below the walking mechanism through mechanical arms, wherein the walking mechanism comprises a back walking wheel which is clamped at a part, where icing is removed, of the power transmission line, and a front walking wheel which is clamped at a part, where icing is not removed, of the power transmission line; the rack is provided with a de-icing mechanism; a wireless controller is arranged on the left side of the interior of the rack; the de-icing mechanism comprises an icing smashing module and a water jet cutter cutting module from left to right in sequence; an opening is formed in the top of a water tank; an ice and snow receiving funnel is arranged on the opening; notches are formed in a position, corresponding to the ice and snow receiving funnel, of the top of the rack, and used for collecting ice blocks falling from the power transmission line; and a heating module is arranged at the bottom of the water tank and is in electric signal connection with the wireless controller. Water pressure of the water jet cutter cutting module can be adjusted according to the detected thickness of an icing layer, so that efficient de-icing can be realized during cutting the surface icing without being affected by the thickness of the icing layer, and a line is not damaged either.

Description

technical field [0001] The invention belongs to the technical field of electric power maintenance, and in particular relates to a power transmission cable ice and snow removal device. Background technique [0002] Faults caused by icing on transmission 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 for transmission 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. S...
