Composite pole tower with vertical skeleton and preparation method thereof

Abstract

The invention discloses a composite pole tower with a vertical skeleton and a preparation method of the composite pole tower. The composite pole tower comprises the vertical skeleton, a foam inner core and a composite outer layer; the vertical skeleton is formed by a plurality of sections of hollow cylinders which are sequentially connected in a sleeved mode; the vertical skeleton is filled with the foam inner core; and the outer surface of the vertical skeleton is wrapped with the composite outer layer. The composite pole tower and the preparation method thereof have the advantages that the vertical skeleton is additionally arranged in the pole tower, thus the strength of the pole tower is improved, and the pole tower is not prone to being broken; the vertical skeleton is formed by the multiple hollow cylinders which are movably connected in the sleeved mode, the hollow cylinders are simple in forming process, small in size and convenient to transport, during assembling, no any auxiliary connection piece is needed, the hollow cylinders can be automatically formed only by being pulled to be suspended after being stacked, and the production efficiency can be improved; a process omits a demoulding working procedure; and the foam inner core is directly formed in the vertical skeleton, through the foaming process of the foam inner core, a certain expansion extrusion effect on the vertical skeleton can be generated, thus the vertical skeleton is shaped, and the vertical skeleton can be protected from being corroded.

Description

technical field [0001] The invention relates to the technical field of composite material towers, in particular to a vertical skeleton composite material tower and a preparation method thereof. Background technique [0002] Transmission line tower structure is a special support structure in power overhead line facilities, and its structural performance directly affects the safety, economy and operational reliability of the line. At present, there are many composite towers on the market, which have the advantages of light weight, good corrosion resistance, and reduced demand for mineral resources and environmental pollution, and are gradually being popularized and used. [0003] However, the existing composite material towers have the following two disadvantages: (1) Since the composite material towers are mostly produced by the process of fiber helical winding, the composite material towers manufactured in this way are easy to break, and if they are broken, they cannot be br...
