Problems solved by technology

However, the rigidity of this kind of composite pole is insufficient. When encountering strong winds, the top of the pole will swing back and forth, which will easily damage the wires erected on it. In places where strong winds often occur such as the seaside or mountain passes, this The shortcomings are particularly obvious
The electric pole produced by the above method has poor surface flatness and needs to be polished. Therefore, the electric pole produced by the above method is 2-5mm thicker than the design requirement, and then the thick part is polished to make the surface of the electric pole Flattening, but this wastes raw materials and increases production costs

Abstract

The invention provides a composite pole formed by winding fiber and having high strength and rigidity, good surface finish and low cost. The composite pole comprises the components as follows: 50 to 65 parts of glass fiber, 25 to 35 parts of polyurethane multi-base resin, and 10 to 15 parts of inorganic filling material. The manufacturing method of the composite pole comprises the following steps: the polyurethane multi-base resin and the inorganic filling material are mixed uniformly; the glass fiber is wound on a mould after being steeped with the mixture; and heating and curing are performed to form the composite pole. Under the premise of ensuring the strength of the pole, the inorganic filling material is added in the raw materials; particularly, quartz sand is added to increase the rigidity of the pole, reduce the oscillation angle at the top end of the pole in gale weather and improve the safety of electric wires on the pole; and the method that the glass fiber is steeped with the mixture of the inorganic filling material and the polyurethane multi-base resin through a fiber reinforced plastic winding forming glue injection system instead of a steeping vat improves the strength and the rigidity of the pole and endows the pole with high surface finish.

Description

technical field [0001] The invention relates to the technical field of electric pole manufacturing, in particular to a composite material electric pole and a manufacturing method thereof. Background technique [0002] At present, the poles and towers used in domestic overhead transmission lines mainly include concrete poles, steel pipe poles, steel pipe concrete poles, lattice iron towers, etc. Traditional transmission poles and towers generally have defects such as heavy weight, no insulation, easy to rust, easy to crack, and short service life. , construction, transportation, operation and maintenance are difficult, and various safety hazards are prone to occur. Glass fiber reinforced resin-based composite materials have the characteristics of high strength, light weight, corrosion resistance, good electrical insulation performance, long service life, convenient transportation and construction, and are very suitable for manufacturing transmission line towers. Therefore, c...
