Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] Such as figure 1 , figure 2 As shown, four bearings can be used to install the main shaft 8 and the connecting shaft 9 in parallel on the two side plates of the frame housing 1 in this embodiment; the spring 2 and the first gear 3 are fixed and arranged side by side on the main shaft 8. Other suitable springs such as coil springs or torsion springs, extension springs, etc., the purpose is to make it generate tension that can drive the first gear 3 to rotate. In this embodiment, a planar scroll spring is used, and the planar scroll The inner end hook of the spring is connected in the groove of the main shaft 8, and the outer end hook is connected and fixed with the spring fixing shaft 11 on the frame housing 1; the sheave 4, the third gear 6 and the middle The second gear 5 of the one-way clutch 12 is provided, wherein the sheave 4 can be any suitable sheave s...

Abstract

The invention relates to a wire icing preventer for overhead power transmission lines in the field of power transmission equipment. The wire icing preventer comprises a framework shell, a main shaft, a coupling shaft, a spring, a first gear, a sheave, a second gear, a third gear, a flexible coupling part, an insulator and a wire; the main shaft and the coupling shaft are rotatably mounted in parallel on both side plates of the framework shell; the spring and the first gear are mounted side by side on the main shaft, the outer end of the spring is connected with a fixed shaft on the framework shell, and the inner end of the spring is connected with the main shaft; the sheave, the second gear and the third gear are mounted side by side on the coupling shaft, the second gear and the third gear are engaged with the first gear, and a one-way clutch is arranged at the middle of the second gear; the upper part of the external diameter of the third gear does not have teeth; the flexible coupling part is fixed on the sheave; and the insulator and the wire are connected with the flexible coupling part. The wire icing preventer can remove ice on a power transmission line, so that supporters for the power transmission line can operate under safe load, and thereby, the power transmission line can safely operate under the freezing environment.

Description

technical field [0001] The invention relates to the technical field of transmission line power supply equipment, in particular to a wire anti-icing device for overhead transmission lines. Background technique [0002] According to the erection code of transmission lines in my country, the design standard for the thickness of icing on transmission lines stipulates a standard value. The icing of the power grid brought about by continuous rain, snow and freezing weather is the chief culprit of power grid accidents. When the temperature is around plus or minus 3 degrees Celsius, it is very easy to freeze the power grid equipment under such conditions. Rain and snow adhere to the surface of the power grid wires to continuously form ice coatings. When the freezing is severe, the thickness of the ice coating increases by 1 mm per hour. Transmission lines designed according to the standard are difficult to withstand icing above 60 mm. [0003] There are three main types of ice da...
