Power transmission electric pole and manufacture method thereof

Abstract

The invention relates to the field of power transmission devices, and more specifically, relates to a power transmission electric pole and a manufacture method thereof. The manufacture method comprises following steps: a bended pole can be used to produce the power transmission electric pole, polyurethane and fiber are adopted as raw materials, and a pole production mold is adopted as the mold; two ends of the pole production mold are fixed and the mold is made to rotate; the polyurethane and the glass fiber are made to cover the surface of the pole production mold during rotation until the raw materials uniformly cover the pole production mold; then the pole production mold and the raw materials are baked; then the pole production mold and the raw materials are taken out and the method is finished. The provided bended power transmission electric pole can be used in corners of electric transmission lines. Furthermore, electric poles with different degrees of bending can be manufactured according to different angles of different corners. By use of the power transmission electric pole with certain curvature, a resultant force of pulling forces at two sides of the electric pole around a corner is offset so that pulling lines of traditional power transmission electric poles can be saved, and as a result the cost of wiring is saved.

Description

technical field [0001] The invention relates to the field of power transmission equipment, more specifically, to a power transmission pole and a production and preparation method thereof. Background technique [0002] Electric poles are bridges for electricity, allowing electricity to be transported to various places. The common electric poles we have are wooden poles and concrete poles. They are of different heights. There are many general types of poles, such as: concrete pole, which is a pole made of concrete and steel bars or steel wires. Iron pole: a pole made of pig iron. There are two types of concrete poles: prestressed and non-prestressed. The cross-section of the pole has square, octagonal, I-shaped, circular or other special-shaped cross-sections. The most commonly used are circular section and square section. The length of the pole is generally 4.5 to 20 meters. There are two kinds of ring-shaped poles: tapered pole and equal-diameter pole. The tip diameter o...

Problems solved by technology

[0003] When erecting transmission lines, it is necessary to arrange the direction of the lines according to the transmission site and the terrain between the two places. In the process of line layout, many lines usually cannot be arranged in a straight line throughout the entire process, and there will be corners or arcs. This is why often appear as figure 1 As shown in the "<" arrangement, in this way, the transmission pole at the corner will bear the pulling force of the transmission lines on both sides. If things go on like this, coupled with strong winds, the transmission pole at the corner will be skewed In severe cases, it will fall down, causing great damage to the transmission line.

[0004] Moreover, traditional power transmission poles are mostly made of cement or metal frames, which have a large weight, high transportation costs, and are very troublesome when planted (especially in places where the terrain is more complicated such as mountainous areas); and, For traditional power transmission poles, metal power transmission poles are easy to corrode or weather in the harsh outdoor environment, and need regular surface treatment on them, such as brushing protective paint, etc., while cement power transmission poles are used for a long time or When encountering strong winds, cracks, cracks or even fragments will appear, which intensifies its own damage process, and frequent replacement of transmission poles will greatly increase transmission costs
