Abstract
The invention discloses a super-strength composite material electric pole. The electric pole comprises a pole body, and the pole body comprises an inner layer, a middle layer and an outer layer; the inner layer is a fiber yarn spiral winding layer, the middle layer is a fiber yarn axial zero laying layer, and the outer layer is a fiber yarn spiral winding layer; and the electric pole is a hollow thin-wall tubular object with a taper, the fiber yarn axial zero laying layer is divided into multiple layers, and each layer is spirally wound and bound by single-bundle fiber yarn. The inner layer and the outer layer are each formed by uniform spiral winding of a plurality of bundles of resin-soaked fiber yarn. The laying thickness of the middle layer accounts for 1/5 to 4/5 of the wall thickness of the pole body. Due to the fact that axial zero fiber yarn is laid on the middle layer of the electric pole body, the bearing force and rigidity of the electric pole are greatly improved, and the specific strength of the electric pole is higher.
Description
Technical field
The present invention relates to a kind of electric pole, specifically a kind of superhigh intensity composite material electric pole。
Background technology
The shaft tower used in China's overhead transmission line has cement electric pole, steel pipe pole and lattice steel tower。Conventional cement bar, steel pipe pole and framework formula steel tower weight are big, it is easy to cracking, corrosion, conduction, transport mounting cost height；Composite material electric pole has the advantages such as lightweight, intensity is high, corrosion-resistant, the circulation of wet-heat resisting, freeze-thawing resistant destroys, fire-retardant, electrical insulation capability good, long service life, transport mounting cost are low, it is possible to improve and overcome the disadvantages mentioned above of tradition transmission tower。
Composite material electric pole intensity is very high, weight is very light, and the primary index therefore weighing composite material electric pole performance is specific strength；And cement electric pole is very heavy, the primary two indices weighing cement electric pole performance is bearing capacity and stiffness。In the body of rod of taper composite material electric pole, continuous lay axial zero degree silvalin is extremely difficult, the continuous lay of evenly distributed axial especially in the form of a ring zero degree silvalin is with fixing extremely difficult continuously, produce the commonly used silvalin winding process of taper composite material electric pole at present, Wiring apparatus and the intrinsic limitation of winding process cannot realize axially laying pure longitudinal direction along electric pole, i.e. axial zero degree silvalin, is wound around the winding angle of silvalin and electric pole axial line between 7 °-90 °。Realizing the axial zero degree lay of silvalin is improve composite material electric pole bearing capacity and stiffness the most effective method, the final specific strength improving composite material electric pole。
The electric pole wall thickness that winding process produces presents the situation that top end thickness butt is thin, and this defect can be amplified along with the increase of electric pole length and wall thickness。Electric pole is in use, buried depth point stress near butt is maximum, and the wall thickness of the composite material electric pole that winding process produces is that top end thickness butt is thin, the wall thickness phenomena of inversion of this electric pole top end and butt and can not the defect of axial zero degree lay down fibre yarn, make the composite material electric pole that silvalin winding process produces limit and hinder giving full play to of material property。This electric pole in use top end amount of deflection is big, and electric pole easily by the impact of wind and wire tension, causes waving, and rocking tendency is big。
It addition, silvalin pultrude process cannot produce tapered electric pole, therefore there is presently no the taper composite material electric pole of the axial zero degree silvalin of step lay。
Summary of the invention
It is an object of the invention to provide the superhigh intensity composite material electric pole that a kind of bearing capacity is big and rigidity is strong。
For achieving the above object, the technical solution adopted in the present invention is:
Superhigh intensity composite material electric pole, including the body of rod, the described body of rod includes internal layer, intermediate layer and outer layer, and internal layer is silvalin spiral winding lay layer, and intermediate layer is the axial zero degree lay layer of silvalin, and outer layer is silvalin spiral winding lay layer。
Further, the described electric pole body of rod is the hollow tubular body with tapering。
Further, the axial zero degree lay layer of described silvalin is divided into multilamellar, and every layer of axial zero degree silvalin having infiltrated resin is by single fiber-bundles yarn spiral winding colligation。
Further, described internal layer and outer layer are all be entwined by the silvalin uniform spiral of multi beam infiltration resin。
Further, the lay thickness in described intermediate layer accounts for the 4/5 1/5 of body of rod wall thickness。
Further, the axial zero degree silvalin in described electric pole body of rod intermediate layer is from electric pole butt toward top end from short to long successively step by step in step lay。
Further, described electric pole body wall thickness is that the thin butt of top end is thick, and the wall thickness of electric pole is from butt to the uniform gradual change of top end thickness。
Beneficial effects of the present invention: due to laies a large amount of in the electric pole body of rod is axial zero degree silvalin, greatly improves the specific strength of electric pole, and the bearing capacity and stiffness making electric pole is higher。
