Electric transmission line deicer

Abstract

The invention discloses an electric transmission line deicer. The electric transmission line deicer comprises at least two deicing machines arranged on an electric transmission cable, and each two adjacent deicing machines are connected with each other through a rope or a connecting plate. Every deicing machine comprises a deicing mechanism, a power mechanism, a feeding mechanism and a shell, the deicing mechanism and the feeding mechanism are connected with the power mechanism, the deicing mechanism comprises a deicing wheel and a deicing drive mechanism, the deicing wheel is in the shape of a ring less than 360 degrees, a minimum distance at a notch of the deicing wheel is greater than a diameter of the electric transmission cable, and a deicing knife is arranged on the deicing wheel. Every deicing drive mechanism comprises a power wheel A, two intermediate wheels and four planet wheels, wherein the four planet wheels mesh with the deicing wheel, each intermediate wheel meshes with two of the four planet wheels, the power wheel A meshes with the two intermediate wheels and is connected with the power mechanism, and a meshing area of the deicing wheel and the planet wheels is greater than 180 degrees. The notches of the deicing wheels can allow the electric transmission cables to pass through, and the electric transmission line deicer can clamp the external portions of the electric transmission cables.

Description

technical field [0001] The invention relates to a power transmission line deicer, in particular to a device that can be snapped in from the outside of the cable to clean the ice on the cable. Background technique [0002] In 2008, a snow disaster occurred in southern China, and an important electricity transmission channel from Yichang to Shanghai for the Three Gorges Project of the State Grid was interrupted due to the severe snow disaster for several days. A person from the State Grid Corporation of China said that the main reason for the accident was that the section of the line involved in the accident was covered with ice that was too thick, with a maximum thickness of 50 to 60 millimeters. According to the perennial climate in the south of the Yangtze River, the designed ice thickness is only 10 millimeters. The air in the south is humid, and it is easier to freeze once encountering low temperature weather. [0003] With the influence of the greenhouse effect, climate...
