Problems solved by technology
[0009] The purpose of the present invention is to solve the problem that in the preparation process of the existing power generation and transmission towers, the tensile strength is not high due to the lack of longitudinal fibers, or the preparation process is complicated, and molds with matching sizes are required, resulting in high mold costs and difficult demoulding. A series of problems, inventing a method to prepare a composite tower with axial fibers without a mold

Embodiment Construction
[0036] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0037] like figure 1 , 2 shown.
[0038] A coreless molded composite pole tower, the cross-sectional shape of which is circular tube or polygonal (such as square tube, rhombus or hexagonal), and the cross-sectional area is large at one end and small at the other end with a smooth transition. It consists of at least A layer of longitudinal composite material (such as carbon fiber, glass fiber, basalt fiber, etc., the same below) fiber layer 9 along the axial direction and at least one layer of oblique composite material fiber wound on each layer of longitudinal composite material fiber layer 9 The winding layer 10 is composed of the longitudinal fiber layer 9 and the oblique fiber winding layer 10 connected by thermosetting adhesive, such as figure 1 shown.

The invention relates to a coreless moulding composite material pole tower and a manufacturing method thereof. The coreless moulding composite material pole tower is characterized by comprising at least one longitudinal fiber layer (9), at least one slant fiber winding layer (10), wherein the longitudinal fiber layers (9) are along an axial line direction; the slant fiber winding layers (10) are wound on each longitudinal fiber layer (9); and the longitudinal fiber layers (9) and the slant fiber winding layers (10) are bonded and connected through thermosetting glues. With the manufacturing method disclosed by the invention, the key of manufacture lies in that the traditional mould is replaced with the support of a middle rotating support ring when the middle rotating support ring is usedfor slant winding after axial fibers are completely spread. The invention has the advantages of convenience for manufacture, low cost, high product strength, light weight and high cost performance.
Description
technical field [0001] The invention relates to a hollow tower rod for transmission lines, in particular to a wind power generator tower and a high-voltage transmission tower rod made of composite materials, in particular to a method for preparing a coreless molded composite material tower rod . Background technique [0002] At present, the most widely used towers in domestic and foreign transmission lines mainly include wooden towers, concrete or prestressed concrete towers, steel pipe concrete towers, steel pipe poles and iron towers. Therefore, traditional transmission towers generally have defects such as large quality, perishability, corrosion or cracking, poor durability, short service life, difficulties in construction, transportation, operation and maintenance, and are prone to various safety hazards. Wood poles will corrode and steel will rust, so regular inspections and repairs are required. The use of antirust compounds also has a detrimental effect on the envir...
