Abstract
Description
Technical Field
[0001] This utility model relates to the field of utility pole technology, specifically to a composite material utility pole. Background Technology
[0002] Composite material poles are poles made of materials such as glass fiber reinforced plastic. Compared with traditional poles, they have advantages such as being lightweight and corrosion resistant, as well as good insulation and shock resistance. They are mainly used in urban power grids, highways and other places.
[0003] To reduce space occupation and facilitate storage and transportation, some composite material poles are divided into multiple sections. These sections can be spliced together during installation and stacked for storage, reducing space occupation. However, during the use of multi-section composite material poles, the inventors discovered that rainwater easily seeps into the joints of existing poles after splicing and assembling, causing rust or corrosion at the joints and affecting the structural strength of the composite material poles. Utility Model Content
[0004] Based on the above description, this utility model provides a composite material pole to solve the problem that rainwater easily seeps into the joints of existing multi-segment composite material poles during use, causing rust or corrosion and affecting the connection strength of the poles.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A composite material pole includes a lower pole body and an upper pole body. The two ends of the lower pole body and the upper pole body that are close to each other are both tapered. The tapered end of the lower pole body is threadedly connected to the tapered end of the upper pole body and overlaps with it. A sealing element is installed between the tapered end of the lower pole body and the tapered end of the upper pole body.
[0006] Based on the above technical solution, the present invention can be further improved as follows.
[0007] Furthermore, one end of the lower rod is tapered and extends outward from the lower rod, and a threaded opening is provided in the center of the tapered end of the lower rod.
[0008] Furthermore, a tapered groove is provided at one end of the upper rod, with the smaller end of the tapered groove facing the inside of the upper rod, and the size of the tapered groove is the same as the size of the tapered end of the lower rod.
[0009] Furthermore, the sealing element includes a gasket, a through hole, and an extension. The gasket is conical, with the outer conical end of the gasket installed inside the conical groove and engaging with it. The inner conical end of the gasket is installed outside the conical end of the lower rod and engaging with it.
[0010] Furthermore, the through hole is formed on the surface of the gasket, the axis of the through hole coincides with the axis of the threaded opening, and the diameter of the through hole is equal to the diameter of the threaded opening.
[0011] Furthermore, the extension is arranged in a ring at equal intervals on the outer side of the pad and extends toward both sides of the pad. The extension is arc-shaped and its axis coincides with the axis of the upper rod and the lower rod. The inner side of the extension is in contact with the surface of the upper rod and the lower rod.
[0012] Furthermore, a threaded rod is provided at the center of the inner side of the tapered groove, the threaded rod passes through the through hole and is threadedly connected to the threaded opening.
[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:
[0014] This utility model, through the conical groove and the conical end of the lower pole, allows the connection between the upper and lower poles to bulge outwards in a conical shape towards the upper pole during assembly, forming a certain angle of inclination. Combined with the sealing element installed between the upper and lower poles, this effectively prevents rainwater from seeping into the lower and upper poles, avoiding rust and corrosion at the connection point and ensuring the structural strength of the composite material pole assembly.

[0021] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.
[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0023] Please see Figure 1-4 The present invention relates to a composite material pole, comprising a lower pole body 1 and an upper pole body 3. The two ends of the lower pole body 1 and the upper pole body 3 that are close to each other are tapered. The tapered end of the lower pole body 1 is threadedly connected to the tapered end of the upper pole body 3 and overlaps with it. A sealing element 2 is installed between the tapered end of the lower pole body 1 and the tapered end of the upper pole body 3.
[0024] Please see Figure 2 One end of the lower rod 1 is tapered and extends outward. A threaded opening 11 is provided in the center of the tapered end of the lower rod 1. One end of the upper rod 3 is provided with a tapered groove 31. The smaller end of the tapered groove 31 faces the inside of the upper rod 3. The size of the tapered groove 31 is the same as the size of the tapered end of the lower rod 1. The tapered end of the lower rod 1 can engage with the tapered groove 31 of the upper rod 3 and form a certain tilt angle towards the upper rod 3. In rainy weather, due to the influence of the tilt angle of the connection between the upper rod 3 and the lower rod 1, rainwater cannot flow backward into the space between the upper rod 3 and the lower rod 1, effectively preventing rainwater from causing rust and corrosion to the connection between the upper rod 3 and the lower rod 1, and ensuring the structural strength of the spliced assembly of the upper rod 3 and the lower rod 1.
[0025] Please see Figure 2 The sealing element 2 includes a gasket 21, a through hole 22, and an extension 23. The gasket 21 is conical. The outer conical end of the gasket 21 is installed inside the conical groove 31 and fits into the conical groove 31. The inner conical end of the gasket 21 is installed outside the conical end of the lower rod 1 and fits into the conical end of the lower rod 1. The through hole 22 is opened on the surface of the gasket 21. The axis of the through hole 22 coincides with the axis of the threaded opening 11. The diameter of the through hole 22 is equal to the diameter of the threaded opening 11. The gasket 21 is mated between the conical groove 31 of the upper rod 3 and the conical end of the lower rod 1, which can increase the sealing between the upper rod 3 and the lower rod 1 and effectively prevent rainwater from entering the conical groove 31. The opening of the through hole 22 provides a path for the connection between the threaded rod 4 and the threaded opening 11. When the gasket 21 is sealed between the upper rod 3 and the lower rod 1, the threaded rod 4 can pass through the gasket 21 and form a connection and fixation with the lower rod 1.
[0026] Please see Figure 1 The extension 23 is arranged in a ring at equal intervals on the outside of the gasket 21 and extends toward both sides of the gasket 21. The extension 23 is arc-shaped and its axis coincides with the axis of the upper rod 3 and the lower rod 1. The inner side of the extension 23 is in contact with the surface of the upper rod 3 and the lower rod 1. The extension 23 can simultaneously contact the surface of the upper rod 3 and the lower rod 1, increasing the contact area and friction. This makes it less likely for the upper rod 3 or the lower rod 1 to loosen after being threaded together by the threaded rod 4, thus increasing the structural strength and stability of the upper rod 3 and the lower rod 1 after being threaded together.
[0027] Please see Figure 4 A threaded rod 4 is provided in the center of the inner side of the tapered groove 31. The threaded rod 4 passes through the through hole 22 and is threadedly connected to the threaded opening 11. The upper rod body 3 is fixed to the lower rod body 1 by threaded connection through the threaded rod 4 and the threaded opening 11. The sealing element 2 is clamped and fixed during the threaded connection between the upper rod body 3 and the lower rod body 1. This connection method is simple to operate and facilitates the installation and disassembly of the upper rod body 3, the lower rod body 1 and the sealing element 2 by the staff.
