Problems solved by technology

The invention uses the cutting part to cut the ice coating first, and then knocks the cut ice coating through the knocking part, which can de-ice some ice coatings with a thicker ice layer, but the cutting part of the invention uses a cutting cutting the ice-covered sheet, this method has the disadvantages of unsatisfactory cutting effect, easy damage to the power line and inability to protect continuously

Embodiment 1

[0034] An on-line deicing device for power transmission lines, including a traveling mechanism and a frame 2 connected below the traveling mechanism through a mechanical arm 1. The wheel 3 and the front road wheel 4 stuck on the ice-covered part of the power transmission line 32, the deicing mechanism is set on the frame 2, and the deicing mechanism is located between the rear road wheel 3 and the front Between the walking wheels 4, a wireless controller 5 is arranged on the left side inside the frame 2, and the traveling mechanism is electrically connected to the wireless controller 5; the deicing mechanism includes ice-coated crushing modules in sequence from left to right 6 and the water knife division module 7; the frame 2 is provided with a drying mechanism for drying the power transmission line 32 and a spraying mechanism 33 arranged at the rear of the drying mechanism and used for spraying water-repellent agent.

[0035] The drying mechanism includes a drying module 34 ...

Embodiment 2

[0045] It differs from Embodiment 1 in that: the water tank 23 is provided with a water inlet, the water inlet is connected with a water pipe 25, and the lower end of the water pipe 25 is connected with a quick joint 26, and the quick joint 26 is used to connect to the water tank on the ground. A water pump is used to add water to the water tank 23.

[0046] In this embodiment, a water inlet is provided on the upper part of the water tank, and the water inlet is connected with a water pipe, and the lower end of the water pipe is connected to the water pump on the ground through a quick joint, so that the water tank can be filled through the water pipe as required, thereby increasing the online capacity of the trolley. Working hours; the water-repellent agent adopted in this embodiment pressurizes the material storage tank by an air pump, then the water-repellent agent in the material storage tank is delivered to the spray nozzle through the paint pipe at its lower part, and an ...

Embodiment 3

[0048] The difference between it and the second embodiment 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 30 that is slidingly arranged at the bottom of the frame 2 using a dovetail structure and a counterweight 30 that is arranged on the bottom of the frame 2. 2 The automatic telescopic rod 31 on the left side of the bottom, the free end of the automatic telescopic rod 31 is connected with the counterweight 30, and the automatic telescopic rod 31 is connected with the wireless controller 5 by electrical signals.

[0049] The automatic telescopic rod 31 is an electric telescopic rod.

[0050] 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 trolley, so as to avoid the instability of the center of gravity from affecting the work of the trolley; The position of the block can be used...

Abstract

The invention discloses an on-line de-icing device for a power transmission line. The on-line de-icing device comprises a walking mechanism and a rack which is connected to the lower portion of the walking mechanism through mechanical arms. The walking mechanism comprises a rear walking wheel and a front walking wheel, wherein the rear walking wheel is clamped on the de-iced portion of the power transmission line, and the front walking wheel is clamped on the icing portion of the power transmission line, a de-icing mechanism is arranged on the rack and located between the rear walking wheel and the front walking wheel, a wireless controller is arranged on the left side inside the rack, and the walking mechanism is connected with the wireless controller through electric signals; the de-icing mechanism comprises an ice cover crashing module and a water jet cutter dividing module in sequence from left to right. The water pressure of the water jet cutter dividing module can be adjusted according to the detected thickness of an ice cover layer, so that the on-line de-icing device efficiently carries out de-icing without being affected by the thickness of the ice cover layer when the surface ice cover is divided, and also will not damage the line.

Description

technical field [0001] The invention belongs to the technical field of electric power maintenance, and in particular relates to an online deicing device for power transmission lines. 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. So...
