Self-obstruction type transmission line deicing device

Abstract

The invention discloses a self-obstacle-crossing power transmission line deicing device. The self-obstacle-crossing power transmission line deicing device comprises a frame, a deicing mechanism and awalking mechanism, and the deicing mechanism and the walking mechanism are arranged in the frame; the frame comprises a base plate and a vertical plate which is arranged on one end of the base plate and has adjustable length, and a pressure plate is provided with a power supply mechanism; the walking mechanism comprises a walking wheel driven by a power mechanism, and a compaction wheel I and a compaction wheel II, and the walking wheel, the compaction wheel I and the compaction wheel II form a concentric cavity; the walking wheel is hinged to one end, of the vertical plate, being far from thepressure plate through a shaft rod by means of a horizontal support; the compaction wheel I and the compaction wheel II are hinged to the base plate through shaft rods by means of vertical supports;each shaft rod is provided with a torsion spring; the base plate is provided with a control mechanism and a signal transmitting and receiving mechanism connected with the control mechanism, and the vertical plate achieves length adjustment when being driven by the power mechanism. The self-obstacle-crossing power transmission line deicing device can automatically climb over obstacles in the horizontal and vertical directions, and the deicing device is installed and recovered through an unmanned plane.

Description

technical field [0001] The invention relates to the technical field of deicing power transmission lines, in particular to a self-obstacle-over-obstacle deicing device for power transmission lines. Background technique [0002] Icing transmission lines in winter is one of the biggest natural disasters in power systems. Rime is formed when freezing rain falls on objects with a temperature below freezing. If it is condensed on the wire, it forms wire icing. The icing of wires will cause great damage to lines, iron towers, etc., and the repair of accidents such as power supply interruptions caused by icing is difficult and takes a long time. [0003] At present, for 220KV transmission lines, double-split conductors are generally arranged. In order to prevent the double-split sub-conductors from attracting each other, colliding, and twisting together under the action of wind, a two-split spacer is installed between the two conductors. To better prevent breeze vibration and imp...

Problems solved by technology

When the clamping obstacle-crossing device encounters the spacer, the front and rear travel wheels contact the upper part of the spacer, and the clamping wheel matched with the front and rear travel wheels contacts the lower part of the spacer. Under the further action of the driving force, the spacer forces the slider to Move downwards in the vertical chute to further compress the elastic member. When the obstacle-crossing device is clamped to complete the obstacle-crossing of the spacer bar, the distance between the front and rear traveling wheels and the corresponding clamping wheels decreases, and the shape of the spring in the vertical chute The variable is reduced accordingly, and the deformation of the initial working state is restored, but the clamping obstacle climbing device cannot automatically climb over obstacles in the vertical direction

[0006] When the above deicing device is installed, personnel need to go up to the corresponding iron tower for high-altitude installation, and high-altitude climbing in ice-covered weather is very dangerous
