Problems solved by technology

[0004] The object of the present invention is to address the above problems, to provide a power transmission line anti-icing device to solve the problem of power transmission line icing, suitable for overhead ground wires and single conductors without joints in the stalls, so that the power transmission and distribution lines are protected during the icing season. There is no icing phenomenon, so as to avoid the accidents of power transmission and distribution lines being broken due to severe icing, and greatly improve the operation stability and reliability of power transmission and distribution lines

Embodiment Construction

[0017] As shown in the figure, a transmission line anti-icing device mainly includes a base (1), a support frame (2) and a rain cover (15), and is characterized in that the support frame (2) is equipped with vertical The transmission shaft (3), the top of the transmission shaft (3) is connected with three wind cups (4) with the same interval angle on the horizontal plane through a rod, and the wind cup (1) is hemispherical, used to collect wind force and surround the transmission shaft (3) Perform rotation.

[0018] The upper transmission gear (5) and the lower transmission gear (6) are fixedly installed in the middle of the transmission shaft (3). The upper transmission gear (5) and the lower transmission gear (6) are opposite helical gears. When the transmission shaft (3) When rotating, the upper transmission gear (5) and the lower transmission gear (6) also rotate thereupon.

[0019] The lower end of the transmission shaft (3) is connected to the steering guide device (13)...

Abstract

The invention discloses an anti-icing device for power transmission lines. The anti-icing device mainly comprises a base, a support frame and a rain cover, wherein a drive shaft in the vertical direction is arranged on the support frame, the top of the drive shaft is connected with a wind cup for collecting wind power by a rod, an upper drive gear and a lower drive gear are fixedly arranged at the middle part of the drive shaft, the lower end of the drive shaft is connected with a steering guide device, an upper roller compound gear is arranged on the support frame on one side between the upper drive gear and the lower drive gear, and the upper roller compound gear is driven by the upper drive gear or the lower drive gear under the control of the steering guide device. The anti-icing device can travel on overhead ground wires by means of wind power without other power and travel positively and negatively by means of the steering guide device, and when the anti-icing device travels, a brush clears frozen rain, soft rime and flying snow attached to the overhead ground wires, so that the overhead ground wires are prevented from icing.

Description

technical field [0001] The invention relates to a power supply line device, in particular to a power line anti-icing device. Background technique [0002] The ice disaster in 2008 has left a deep impression on many power grid personnel. In the southern region, especially in high-altitude mountainous areas, most of the lines have been downed and disconnected, causing many large-scale power outages. Afterwards, the State Grid gradually increased the power grid construction, improved the design standards, and implemented differentiated anti-freezing designs for some lines and local sections. In order to prevent the line from being iced and cause another accident of wire breakage, a variety of wire AC and DC ice melting technologies have been studied at home and abroad and used in actual operation, and the technology is becoming more and more mature. The anti-icing and deicing measures for overhead ground wires are mainly current melting ice (that is, transforming overhead grou...
