Problems solved by technology

[0002] Traditional reinforced concrete poles and iron towers have the problems of bulkiness, difficulty in installation, and short service life. As for iron towers, metal is an excellent conductor and has a high thermal conductivity. In addition to many problems such as ice, anti-corrosion and anti-rust treatment must be done every year, and the risk of anti-theft is also very high. The power grid requires a lot of manpower and material resources to maintain

Embodiment Construction

[0010] figure 1 The composite material transmission tower shown in the figure has a conical tubular structure, using thermosetting resin as the matrix, continuous glass fiber yarn as the reinforcement material, and a layer of glass fiber yarn soaked in resin is used for composite material winding process. One layer is wound on the surface of the tapered tubular mandrel. After the whole is solidified, the tapered tubular structure is formed by demolding, which is used in the field of power transmission towers. The above-mentioned glass fiber yarns are wound on the surface of the mandrel layer by layer. The angle A between a part of the glass fiber yarn 1 and the rotation axis 3 of the mandrel is 0°≤A≤15°, and the angle B between the glass fiber yarn 2 wound on the other part and the rotation axis 3 of the mandrel is 30°≤B≤ 90°, the thermosetting resin is unsaturated polyester resin, vinyl resin, epoxy resin or polyurethane resin.

Abstract

The invention discloses a composite material transmission tower, which has a conical tubular structure. Thermosetting resin serves as a matrix, continuous glass fiber yarns serve as a reinforcing material, and the glass fiber yarns impregnated with the resin are wound on the surface of a conical tubular core mold layer by layer through a composite material winding process, wherein an included angle (A) between one part of the glass fiber yarns and a rotating axis of the core mold is more than or equal to 0 degree and less than or equal to 15 degrees, and after the whole is cured, the conical tubular structure is formed through demolding. The composite material transmission tower has high axial strength, high axial modulus and high flexural strength; and during outdoor use, the transmission tower has high acid resistance, alkali resistance and ageing resistance, and the service life is 25 to 100 years.

Description

technical field [0001] The invention relates to a power transmission pole and tower in the field of power transmission, in particular to a composite material power transmission pole and tower. Background technique [0002] Traditional reinforced concrete poles and iron towers have the problems of bulkiness, difficulty in installation, and short service life. As for iron towers, metal is an excellent conductor and has a high thermal conductivity. In addition to many problems such as ice, anti-corrosion and anti-rust treatment must be done every year, and the risk of anti-theft is also very high. The maintenance of the power grid requires a lot of manpower and material resources. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a utility pole that uses composite pipes to replace traditional concrete and iron towers, and has the characteristics of corrosion resistance and high axial strength. [0004] In order to so...
