[0032] In order to enable those skilled in the art to better understand, the technical solutions of the present application are further described below in combination with the drawings and embodiments. Embodiment one

[0033] As Figure 1 And Figure 2As shown, a composite material communication pole includes a communication pole body 1, with a central through hole 2 inside the communication pole body 1. The outer contour of the cross-section of the communication pole body 1 is a regular hexagon. Three reinforcing plates 3 are arranged in a Y-shape along the length direction of the communication pole body 1 inside the central through hole 2. The inner ends of the three reinforcing plates 3 are connected together at the center of the central through hole 2, and the outer ends are connected to the corners of the regular hexagon on the inner wall of the communication pole body 1 at a distance of one corner. The inner wall of the communication pole body 1 has rounded corners 5 at the corners of the regular hexagon. Reinforcing steel bars 4 are pre-embedded at the corners of the regular hexagon along the extension direction of the communication pole body 1. The communication pole body 1 and the reinforcing plates 3 are integrally manufactured, and an injection-molded skeleton 6 is provided inside the communication pole body 1 and the reinforcing plates 3 along the length direction of the communication pole body 1.

[0034] By incorporating multiple reinforcing plates 3 inside the communication pole body 1, the strength of the communication pole can be greatly enhanced. Furthermore, the rounded corners 5 at the edges of the regular polygonal shape on the inner wall of the communication pole body 1 can increase the thickness at the corners, thereby increasing the strength of the corners and making them less prone to breakage and damage. The pre-embedded reinforcing steel bars 4 can further enhance the strength of the communication pole, making it safer to use and extending its service life. This arrangement of reinforcing plates 3 and communication pole body 1 results in a more symmetrical structure, uniform stress distribution, and structural stability. The integrated manufacturing process of the communication pole body 1 and reinforcing plates 3 is also simpler. Example 2

[0035] like Figure 3 As shown, the only difference between Embodiment 2 and Embodiment 1 is that the cross-section of the communication pole body 1 is a regular quadrilateral, and there are two reinforcing plates 3 arranged in an X-shape on the diagonal of the regular quadrilateral of the communication pole body 1.

[0036] This arrangement of the communication pole body 1 and the reinforcing plate 3, where the reinforcing plate 3 divides the cross-section of the communication pole body 1 into four triangles, utilizes the stability of triangles to increase the strength of the communication pole.

[0037] like Figure 4 As shown, a method for manufacturing a composite material communication pole includes the following steps:

[0038] 001. Set up inner mold 7, which is a solid column. Divide inner mold 7 into petals along the length direction according to the polygonal cross-section we need and leave space between each adjacent petal. Attach fiber cloth to the outer surface of inner mold 7.

[0039] 002. Construct a frame by making polyurethane resin into long strips and evenly distributing them along the length of the communication pole body 1 on the outer surface of the inner mold 7 and in the space between adjacent inner molds 7 to form an injection molded frame 6, and fixing the injection molded frame 6 to prevent them from contacting each other tightly.

[0040] 003.Setting up the reinforcing steel 4, the reinforcing steel 4 is arranged at the corner of the polygonal communication pole body 1 along the length direction of the communication pole body 1 and is fixed;

[0041] 004.Covering the outer mold 8, the outer mold 8 is installed outside the inner mold 7 and is closed so that the injection molded framework 6 and the reinforcing steel 4 are located in the space between the outer mold 8 and the inner mold 7, and the fiber cloth is pasted on the inner surface of the outer mold 8;

[0042] 005.Injection molding, injecting the melted polyurethane resin into the space between the outer mold 8 and the inner mold 7, and waiting for it to solidify;

[0043] 006.Demolding, pulling out the communication pole body 1 after solidification from the space between the outer mold 8 and the inner mold 7;

[0044] 007.Cutting, cutting the molded product according to the length of the communication pole body 1 we need.

[0045] The original composite communication pole is made by winding the long strip-shaped composite material on the inner mold 7 along the circumference of the communication pole body 1, and then injection molding, and now our method is to arrange the long strip-shaped composite material on the circumferential surface of the inner mold as the injection molded framework 6 along the axial direction of the communication pole body, which can reduce one winding step and one winding device, and the manufactured communication pole can also prevent transverse fracture, and the internal injection molded framework 6 can also play a role of connecting broken silk, and will not directly break, and is more solid.
