Fiberglass reinforced plastic telegraph pole

Abstract

The invention provides a fiberglass reinforced plastic telegraph pole. The telegraph pole comprises a pole body, a cross arm, lead wire seats, hardware fittings, a clamp, an end cap and a sleeve, wherein the cross arm is arranged on the upper part of the pole body through the clamp; the end cap is arranged on the top end of the pole body; three lead wire seats and the hardware fittings are fixed at two ends of the cross arm and the end cap respectively through bolts; the sleeve is sleeved on the lower part of the pole body; lead wires are fixed between the lead wire seats and the hardware fittings; the pole body is of a hollow conical structure with a uniformly thickened wall, wall thickness variation delta is between 0.15 and 0.2 percent, the wall thickness variation dmax is the maximum wall thickness of the pole body, namely the wall thickness of the lowest end of the pole body, the wall thickness variation dmin is the minimum wall thickness of the pole body, namely the wall thickness of the top end of the pole body, and l is the bus length of the pole body. By adopting the design with a special variable thickness pole body structure, the materials play the best carrying function, and the manufacture cost is reduced; and in the pole body, the fiberglass reinforced plastic flange at the root of the pole body is integrally molded by adopting a winding method, while the telegraph pole is convenient to assemble with the ground, the mechanical performance requirement is met; and the pole body, the cross arm and the lead wire seats are produced by adopting different materials and molding processes, the designable performance, weight reduction and other function requirements are met while corrosion resistance and electric insulation of the telegraph pole are fulfilled.

Description

technical field [0001] The invention relates to a utility pole, in particular to a glass fiber reinforced plastic utility pole, which belongs to the technical field of composite material and utility pole manufacturing. Background technique [0002] At present, the poles and towers widely 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, perishability, corrosion or cracking. Difficult to operate and maintain, prone to various safety hazards. [0003] Glass fiber reinforced resin-based composite materials have the characteristics of high strength, light weight, corrosion resistance, fatigue resistance, durability and electrical insulation performance, and are very suitable for manufacturing transmission towers. The main purposes of research on composite towers at this stage are as follows: [0...

Problems solved by technology

[0014] It can be seen from the literature and patents at home and abroad that both at home and abroad have introduced the mechanical calculation, molding process, and failure analysis of the composite pole body. And the structure, mechanical analysis and molding process of each connecting piece have not been found.
