Description

A kind of assembling type composite material wire pole molded through pultrusion

Technical field

The present invention relates to a kind of electric pole, especially a kind of lightweight, high-strength, corrosion resistant assembling type composite material wire pole molded through pultrusion are particularly useful for mountain area, area such as coastal, high and cold, also can be used for the column structure of advertisement bar, light pole etc.

Background knowledge

The electric pole that uses in the at present domestic and international overhead transmission line mainly contains wooden stick, steel pole and concrete frame.It is wooden stick and steel pole that American-European countries uses more, and what use mainly is concrete frame and China is a large amount of, in 220KV and above circuit, adopts lattice iron tower and sectional type steel pipe pole at present more.But the concrete frame quality is heavier, inconvenient, easy to crack, the poor durability of transportation, and is difficult to reach certain height.And steel pole deadweight is bigger, and tower height does not increase, and not only weight is big and cost is too high again if adopt high-strength steel.Also there are problems such as easy-to-rust, construction transportation and operation maintenance difficulty in steel pole and iron tower simultaneously.In addition, lightning strike accident and pollution flashover accident almost respectively account for 50% in the transmission line of electricity tripping operation accident in every year, a large amount of composite insulators that use still can not thoroughly solve thunder and lightning and pollution flashover accident, therefore the national economy loss that is caused is bigger, therefore employs new technology, that new material is made electric pole is extremely urgent.

Fibrous composite has high-strength light, corrosion-resistant, weatherability and the good remarkable advantage of electrical insulation capability.Pultrude process is that fiber bundle or fabric are fed continuously by creel, process resin glue groove is with fiber impregnation, enter withdrawal mechanism after passing hot forming tool again, can be made into continuous composite product by this flow process, pultrude process can be produced the continuous section bar of cross sectional shape complexity.Therefore the pultrusion molding process that can adopt serialization to produce prepares composite material electric pole or composite material electric pole parts, electric pole will promptly be formed after the composite material component assembly unit, than conventional concrete bar, steel pole, not only on weight, alleviate greatly, be easy to install and construction, especially be fit to the area, mountain area.Simultaneously composite material electric pole has good electric insulation, performance such as corrosion-resistant, is suitable for areas such as coastal, high and cold.The present invention proposes a kind of assembling type composite material wire pole, its main innovation is its assembly type double-walled construction, can significantly strengthen the anti-flexing unstability performance of cylinder, composite material component adopts the pultrusion molding process serialization to produce, after being assembled into the double-walled cylinder, be used for column structures such as electric pole, advertisement bar, light pole.

Summary of the invention

The objective of the invention is to develop a kind of novel composite material electric pole in order to adapt to electric pole high-strength light, insulation, requirement such as corrosion-resistant.

Purpose of the present invention can reach by following measure:

A kind of assembling type composite material wire pole molded through pultrusion, mainly comprise the cylindrical of cylindrical wall components composition and the interior circle that the inner round wall parts are formed, one end of described cylindrical wall components is the outer wall termination, the other end is provided with the outer wall bayonet slot that can fasten with the outer wall termination, the inwall of cylindrical wall components is provided with wild card and attaches together and put, one end of inner round wall parts is the inwall termination, the inwall bayonet slot of the other end for fastening with the inwall termination, the outer wall of inner round wall parts are provided with to attach together with wild card puts the interior clamping close device that matches.

Described wild card attaches together that to put with interior clamping close device be bayonet slot, the termination of matching, or the cloudy tongue and groove that matches, positive tongue and groove.

Described outer wall bayonet slot and outer wall termination or cloudy tongue and groove, positive tongue and groove for matching.

Described inwall bayonet slot and inwall termination or cloudy tongue and groove, positive tongue and groove for matching.

Described cylindrical wall components and inner round wall parts are for adopting the whole continuously shaped section bar of composite material pultrusion technology.

Described cylindrical wall components and inner round wall parts are that fiber bundle or fabric and resin solidification form, and fiber bundle or fabric comprise: glass fiber, basalt fibre, aramid fiber or carbon fiber; Resin comprises: unsaturated polyester (UP), vinylite, epoxy resin or phenolic resins, and also can be in pultrusion molding process at the peripheral compound chopped mat of fiber bundle or fabric.

Described cylindrical wall components and inner round wall parts can adopt thermoplastic to make by extruder, and material is preferably plastics.

The quantity of described cylindrical wall components and inner round wall parts is preferably each 8.

The present invention has following advantage:

Compare with other products with composite material electric pole of the present invention, its maximum characteristics are: in light weight, the intensity height, anti-flexing unstability performance is good, corrosion-resistant, convenient transport, assembling construction are simple, convenient and rapid, can be used for mountain area, area such as coastal, high and cold, also can be used for column structures such as advertisement bar, light pole.But this composite material electric pole suitability for industrialized production simultaneously can be by the electric pole of height and load bearing requirements production different size.
