Description

The hollow electric pole of compound enhancing

Technical field

The utility model relates to the hollow electric pole of a kind of compound enhancing, belongs to the electric power facility technology.

Background technology

Existing hollow electric pole is that reinforced concrete pole is commonly called as cement electric pole mostly, or the steel electric pole

Existing this electric pole is owing to heavy the transportation installed inconvenience; Because be easy to corrode weathering, and Acceptable life is limited, and because it belongs to the electric conductor electric pole, and the service condition harshness, the insulation measures strictness that matches with it.

The researcher is owing to after the reason that material factor caused, begin research and development and adopt compound enhancing resin material in many deficiencies of recognizing existing electric pole, comes instead of steel reinforced concrete or steel, prepares hollow electric pole.Be called " electric force pole tower of making of composite material " disclosed technological process of production such as Chinese patent publication number CN1350024A name: by the cementing agent that resin and additives mixed are produced, be applied to glass fabric or carbon cloth two sides, the Wrapping formed then mould that is inserted in again pushed one hour, and preparation finished product composite electrical shaft tower.Though this patent application has overcome many deficiencies of existing cement electric pole and steel electric pole, but also be not difficult to understand, the axial mechanics poor-performing of this patent application finished product electric pole, thereby, physical properties such as its tensile strength, compressive strength, moment of flexure, amount of deflection, shaft moment of torsion, all can not get certain assurance, particularly big at body of rod height, use the big and shaft of on-the-spot pole clearance stressed big and under strong convective weather environment such as storm, said electric force pole tower still exists hidden danger such as bending even fracture.

Summary of the invention

The purpose of this utility model is to provide physical properties such as a kind of tension compressive strength and shaft moment of torsion better, and the hollow electric power bar of the compound enhancing of longer service life is to overcome the deficiency of prior art.

The utility model realizes that the technical scheme of its purpose is

The hollow electric pole of a kind of compound enhancing, its body of rod is frustum; The body of rod by several layers along its radially continued circling arrange around fibrage, and be in adjacent ring around between the fiber and adjacent 2 layers form around the resin tack coat between the fibrage, its improvement is: in the skin of the body of rod, along the circumferential direction be provided with some along the axial arranged fiber bundle of the body of rod, and said fiber bundle layering is located at adjacent ring between fibrage.

Can understand that by above given technical scheme the utility model is owing in the body of rod outer and arranged fiber bundle vertically, effectively strengthened the axial mechanical property of the body of rod, and the while has effectively been improved the radial mechanical performance of the body of rod.Thereby realized the purpose of this utility model.

The further improvement of the utility model point is:

Around the fibrolaminar number of plies in 10～40 layers of scope; The axial direction fibre bundle divides 2～5 layers of layout, and adjacent 2 layers fiber bundle staggers mutually and along the circumferential direction evenly arranges.That is to say that the sidewall thickness of the utility model hollow rod body is in 10～100mm scope.This is that the utility model is according to electric power bar gauge lattice at present commonly used and load thereof, through preferred after the repetition test.Certainly, the utility model is not subjected to said restriction around fibrage number of plies scope.

Said resin tack coat is the resin tack coat that includes quartz sand.The utility model advocates that the particle diameter of quartz sand is in 0.1～2mm scope.Because the existence of quartz sand will further improve mechanical property of the present utility model undoubtedly.And used quartz sand, can blending in resin, by said fiber impregnation blending the resin of quartz sand is arranged after, Wrapping formed again.Also can in dipping resin fiber winding process, adopt funnel to compose material or gas blowout mode, the quartz sand tax is sprayed on the dipping resin fiber.

At the inner chamber of the body of rod, also be filled with expanded material, and said expanded material is rigid foamed or foam cement.Its purpose obviously is further to improve mechanical property of the present utility model, especially further improves the shaft moment of torsion, moment of flexure and compressive strength.

At the inwall of the body of rod, be provided with the chopped strand tree resin layer.Said chopped strand, what the utility model was advocated especially is short glass fiber.Because body of rod inwall has been set up the weak point of thickness in 5～20mm scope by centrifugal casting and cut tree resin layer, and the chopped strand layer is arranged in such the utility model, and the axial direction fibre bundle is arranged in the skin, its mechanical property will be optimized more.

At the inner chamber of chopped strand tree resin layer, also be filled with expanded material, and said expanded material is rigid foamed or foam cement.

The body of rod can be divided into plurality of sections and constitute an integral body by tapered section grafting inside and outside several respectively; The axial length of inserting section is in 1～2 times of scope in plugging position bar footpath; And be provided with tack coat in plugging position, perhaps be provided with radially riveting component or be provided with tack coat and riveting component radially.Because can implement the segmentation manufacturing according to the height or the title length of the body of rod, this can simplify its production technology equipment undoubtedly and make things convenient for its transportation to install.Because pegging graft is the grafting of inside and outside tapered section, thereby socket connection is reliable and stable.Why will be provided with tack coat or be provided with riveting component in plugging position, its purpose be to prevent the relative rotary motion of plugging position.Said riveting component, what the utility model was recommended is expansion bolt.

The used resin of the utility model is epoxy resin, unsaturated polyester (UP) resin and phenolic resin.Advocate in said resin, to add pigment, fire retardant, age resister, ultraviolet (UV) resistant agent and curing compound simultaneously.

After technique scheme was implemented, what the utility model had was in light weight, and mechanical property is good, easy transportation and installation, and the operating period limit for length, anti-aging, fire-retardant, insulation, anti-environmental corrosion, characteristics such as non-maintaining maintenance and cost of production are low are self-evident.
