Problems solved by technology

The pole material produced by this method has a low density, about 1.4-1.7g / cm 3 , and there are few longitudinal fibers, and the winding fibers have a certain angle, so when the force is applied, the fiber first changes the direction of the force and does not fully bear the resistance, so the bending resistance is low, the elastic modulus is small and the deformation is large, and it cannot withstand large Therefore, it can only be used in power distribution lines, street light lines, road signs, etc., the application range is limited and the production efficiency is low

Embodiment Construction

[0040] see figure 1 , 2 , in a preferred embodiment of the present invention, the tapered pole is assembled by eight trapezoidal slats 7 in a single buckle mode, wherein each of the mother board 8 and the daughter board 9 has 4, the surface of the tapered pole of the present invention The resin-rich fiber tape is radially wound to form a fastening layer, which can enhance the anti-ultraviolet ability, and fasten the tapered utility poles formed by assembling to ensure the proper design strength. The outer surface of the tapered pole is impregnated with an anti-ultraviolet coating 3 to improve the ability to resist atmospheric erosion. The upper end and the lower end of the tapered electric pole all leave the grounding wire inlet and outlet holes 2,5, the upper end grounding wire inlet and outlet hole 2 prevents rainwater from entering, and the lower end grounding wire inlet and outlet hole 5 can drain accumulated water to prevent the pole from ice swelling and rupture. Both ...

Abstract

The invention relates to a tapered pole and a production method thereof. The tapered pole is formed by assembling a plurality of tapered or ladder-shaped strips between mother plates and daughter plates, wherein the mother plates and the daughter plates respectively have the quantity corresponding to the tapered or ladder-shaped strips and are mutually buckled, overlapped surfaces of the strips are adhered, a reinforcing ring is arranged around the inner wall of the taped pole and a fastening layer is radially wound on the outer surface. By using the tapered pole formed by the fastening and the assembling through the combination of a single-double buckling mode of the tapered pole, the rigidity of the assembled tapered pole is improved, and the reinforcing ring can meet the double requirements for the process and the section rigidity; in addition, the surface of the tapered pole is subjected to the resin enriched fiber band radial winding treatment, thus the uvioresistant capacity is enhanced, the tapered pole is fastened and assembled and the deserved design strength is further ensured.

Description

technical field [0001] The invention relates to a tapered electric pole and a production method thereof. Background technique [0002] The poles of overhead power transmission and distribution lines are mostly tapered poles. This kind of pole has a low center of gravity, reasonable distribution of moment at the bending point, relatively light weight and low manufacturing cost compared to equal-diameter poles. However, this kind of pole is mostly reinforced concrete. Electric poles or iron poles are heavy and difficult to transport. [0003] In recent years, foreign countries have vigorously used FRP composite materials to make conical poles. Its advantages are light weight and convenient transportation. It is especially suitable for mountainous areas and areas with inconvenient transportation. Require. [0004] The current production methods of FRP composite poles are mostly formed by impregnating fiber materials with epoxy resin, winding and curing, and also useful for wi...
