Abstract

The invention discloses a cable mechanical de-icing device. Two hanging frames of the traveling mechanism are fixed on the top surface of a main body frame, and traveling wheels and traveling wheels of V type groove wheel are respectively on the hanging frames. A traveling chain wheel is fixedly mounted on the outside of the rear traveling wheel. A rear end of an H shaped bracket of the de-icing device is articulated with the main body chassis; a de-icing wheel shaft, a double-couple de-icing device, and a de-icing chain wheel; and the outer edge of the de-icing wheel is a de-icing tooth. A middle transverse rod of the H shaped bracket is supported by upper and lower support rods connected with a screw assembly in an inclined manner, so that the pitch angle of the de-icing wheel can be adjusted. An outer end of a hub of the de-icing wheel is provided with a convex ram. An ice scoop is mounted in front of the front hanging frame. Motors and a storage battery are fixed at the bottom of the main body frame. The power is transmitted by the chain wheels and the chains. The control mechanism is a control box, and a servo controller therein is connected with two motors to adjust the traveling speed of the device and the rotation speed of the de-icing wheel. An obstacle sensor connected with the control box is arranged in front of the bracket. The device is adapted to the de-icing work of the circular-section common high voltage transmission line below 110kV. The device has simple structure, easy operation and convenient portability.

Description

(1) Technical field

[0001] The invention relates to auxiliary equipment technology for electric power transmission lines, in particular to a cable mechanical deicing device. (2) Background technology

[0002] Ice and snow on transmission lines often cause accidents such as line tripping, disconnection, pole down, conductor galloping, insulator flashover, and communication interruption. Russia, Canada, the United States, Japan, the United Kingdom, Finland, Iceland and my country have all caused safety accidents due to icing of transmission lines, which have brought huge economic losses. Therefore, ice and snow disasters have become a common problem faced by power grids in many countries around the world.

[0003] The short-circuit electrothermal deicing method is a relatively mature and effective means of deicing the power grid under current circumstances. However, there are many drawbacks in the short circuit ice melting method.

[0004] First of all, it is necessary to ad...
