Embodiment 1

[0020] In the deicing device, it includes two semi-cylinders that can be opened freely and have lightening holes, 3 sets of guide members C-C that are evenly arranged in the radial direction of the cylindrical support 1, and 3 sets of guide members C-C that are evenly arranged in the radial direction of the cylindrical support 1. A set of deicing components B-B, and three sets of positioning components A-A evenly arranged in the radial direction of the cylindrical support 1.

[0021] By setting the cylindrical bracket 1 of Φ300×300×10, the guide wheel 14 of the expansion and contraction range can be adjusted in real time according to the uneven ice coating, and the deicing wheel 15 can freely adjust the ice cutting depth, so as to prevent the axis line of the ice-coated ground wire from colliding with the The positioning wheel 23 is offset from the axis line of the deicing device. Guide wheel 14, deicing wheel 15, positioning wheel 23 are arranged radially along cylindrical su...

Embodiment 2

[0024] The guide wheel 14 adopts polytetrafluoroethylene material, which has the characteristics of small thermal expansion coefficient and large sliding friction. Considering the non-uniform ice coating on the ground wire, a set of springs 9 with a diameter of Φ2.5 are installed on the third set of rods 11. During the deicing process, no matter how the thickness of the ice coating changes, the bite force of the guide wheels 14 is always the same. Keep equal, and will not cause failure of cooperation with the positioning wheel 23 due to uneven ice thickness, so as to ensure that the deicing wheel 15 has sufficient ice cutting depth and does not cut the ground wire.

Embodiment 3

[0026] Adopt the deicing wheel 15 of ratchet ice blade as deicing device. The ratchet skates are improved by using rotating skates instead of fixed skates. At the same time, considering the non-uniform ice coating thickness of the ground wire and the different hardness of the ice coating, ordinary circular rotating skates are still prone to jamming during travel. , Therefore, the ratchet ice blade is changed into a gear shape with a certain inclination angle. Since the ice covering of the ground wire is actually a cylinder that wraps the ground wire, it is easier to destroy its stable structure when a force is applied laterally. Therefore, in this example, the edge of the ratchet ice skate is changed from longitudinal cutting to lateral destruction. Considering the different types of ground wires, the ratchet skates need to be effective in deicing on the one hand, and on the other hand, they need to be suitable for various types of ground wires. Before the deicing device is re...

The power transmission line ground wire defroster has the characteristics of simple structure, high deicing efficiency and easy operation.

Description

technical field [0001] The invention relates to the field of deicing electric wires, in particular to a deicing device for ground wires of power transmission lines. Background technique [0002] When encountering ice and snow weather, many high-voltage electric wires and cables are easily broken, resulting in damage to the power line, which has a great impact on production and life. At home and abroad, in addition to manual beating and aircraft spraying deicing agent, there are gunshots, coating special materials on the outside of high-voltage wires and other methods, but these methods are unsafe, low in efficiency, and high in cost. If there is a mechanical method to allow the machine to efficiently remove ice on the wires or wires, and the staff only need to simply install it to start working, then the deicing work will become simple and easy. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a deicing device fo...
