Description

Composite material hollow electric pole

Technical Field

The invention relates to the technical field of electric pole devices, in particular to a composite material hollow electric pole.

Background

The pole is the bridge of electricity, lets the electricity transmit to all places, and we common pole has wooden pole, mixes earth pole and iron pole etc.. Wherein, wooden pole has advantages such as the quality is light, insulating, and the shortcoming is that structural strength is lower, not fire prevention, not corrosion-resistant. The concrete pole has high structural strength, can bear larger weight, and has the defects of large volume and weight and inconvenient installation and transportation. The ferroelectric rod has the advantages of high mechanical strength, long service life and the like, and has the defects of no insulation and weak resistance to atmosphere, water, acid, alkali, salt with common concentration and various oils and solvents.

At present, there are also composite poles made of materials, which refer to a composite pole (CN108049692A) with a clamping structure disclosed in chinese patent, and disclose poles made of glass fiber, of course, there are also some poles made of polyurethane in the prior art; the electric pole structure is more portable and convenient to transport, but most of the installation or splicing structures of the electric pole are connected by adopting the traditional flange;

the flange connection has the advantages of stable structure and good compression resistance; however, there are certain disadvantages: for example, the flange needs special connecting tools, welding (the welding process may also cause damage to the electric pole itself), painting and other processes; the operation is more tedious, and more importantly, the relevant connecting pieces of the flange cannot form a complete set of components with the electric pole in production, additional purchase is needed, and then the assembly of standard parts is carried out, so that the cooperation is lacked.
