Description

Technical Field

[0001] This invention belongs to the field of power pole technology, and in particular relates to an improved power pole. Background Technology

[0002] Power poles are widely used as part of power transmission lines. However, the assembly of existing power poles is troublesome. During assembly and after long-term use, the clamps may slip off, causing assembly trouble and safety hazards. Moreover, the clamps and clamp fixing screws are exposed and prone to rust, making subsequent maintenance and replacement quite inconvenient. The number of cables that existing power poles can carry at the same time is also relatively small.

[0003] CN209083133U discloses a portable segmented cement utility pole, comprising: multiple pole bodies and multiple pole sleeves. The multiple pole bodies are detachably connected end-to-end in a strip shape. Each pole body includes a frame and a bonding layer. The bonding layer includes a support section and a first connecting section and a second connecting section. The end of the first connecting section is provided with a connecting protrusion, and the second connecting section is provided with a connecting groove. The inner wall of the pole sleeve is provided with a first protrusion and a second protrusion corresponding to the fitting. The surface of the connecting section between the first pole body and the second pole body is provided with a first groove and a second groove. By manufacturing the cement utility pole as multiple segmented, splicable pole bodies, multiple pole bodies can be spliced ​​together into a whole at the required installation location before erection. This not only facilitates the transportation of cement utility poles but also improves the flexibility of the erection height, greatly facilitating the erection of utility poles.

[0004] CN213359556U discloses an assembled composite material self-supporting tower, solving the problems of complex molding and inconvenient connection in existing composite material self-supporting towers. It includes a base, main beams, a winding layer, and longitudinal ring structures. The longitudinal ring structure includes an inner support structure and longitudinal ring connectors. The inner support structure includes a winding profile and protrusions, with multiple winding profiles and protrusions arranged sequentially along the circumference. Each protrusion is fixedly connected to a longitudinal ring connector, which is a U-shaped structure including a connecting part, a clamping part, and a winding groove. The connecting part is fixedly connected to the protrusion, and the clamping part has a winding groove on its end face. The number of main beams is the same as the number of longitudinal ring connectors, and the main beams are fixedly connected to the clamping parts. The winding layer is disposed on the winding profile and winding groove. Multiple longitudinal ring structures are arranged vertically along the main beam, which is fixedly connected to the base. It is mainly used for composite material self-supporting towers.

[0005] Therefore, the aforementioned existing technologies cannot solve the existing technical problems. Summary of the Invention

[0006] To address the aforementioned problems, the present invention aims to disclose an improved power pole tower, which is achieved through the following technical solution.

[0007] An improved power pole tower comprises a power pole tower body, a crossarm, a cable-passing component, and a support rod. Its distinguishing feature is the addition of a covering component. The outer edge of the upper part of the power pole tower body has multiple circumferentially continuous and spaced-apart annular grooves. The covering component is a semi-circular arc-shaped cylindrical wall structure with a central covering cavity. Multiple external fixing holes penetrate the wall at its center. Internal fixing holes are located on both sides of the external fixing holes, with countersunk holes at their outer ends. The diameter of the countersunk holes is larger than the diameter of the internal fixing holes. A recessed portion is located at the center of the wall, and the wall thickness at the recessed portion is thinner than the wall thickness without the recessed portion. One end of the crossarm is fixed to the covering component, one end of the support rod is fixed to the covering component and located below one end of the crossarm, and the other end of the support rod is fixed to the lower surface of the crossarm. The cable-passing component is fixed to a surface near the other end of the crossarm. The covering component is inserted into the annular grooves and tightly adhered to and fixed to the power pole tower body.

[0012] The improved power pole described above is characterized in that all cable holes are parallel.

[0013] The improved power pole described above is characterized in that the power pole body is cylindrical.

[0014] The improved power pole described above is characterized in that the power pole body has crossarms distributed in at least a plurality of directions.

[0022] Figure 5 A three-dimensional structural diagram for implementing Example 2. Detailed Implementation

[0023] To enable those skilled in the art to better understand and implement this patent, the markings in the accompanying drawings are explained in detail below.

[0024] In the figure: 1—Power pole body, 11—Annular groove, 2—Covering component, 20—Covering cavity, 21—Outer fixing hole, 22—Inner fixing hole, 23—Recessed part, 24—Counterhole, 3—Crossarm, 4—Cable passage component, 41—Cable passage hole, 5—Cable.

[0025] Implementation Example 1: Please see Figures 1 to 4An improved power pole tower comprises a power pole tower body 1, a crossarm 3, a cable-passing component 4, and a support rod. Its distinguishing feature is the addition of a covering component 2. The outer edge of the upper part of the power pole tower body 1 has multiple circumferentially continuous and spaced-apart annular grooves 11. The covering component 2 is a semi-circular arc-shaped cylindrical wall structure. The center of the covering component 2 is a covering cavity 20. Multiple external fixing holes 21 penetrating the wall are located at the very center of the wall. Internal fixing holes 22 are located on both sides of the walls of the external fixing holes 21. The outer ends of the internal fixing holes 22 have countersunk holes 24. The diameter of the countersunk hole 24 is larger than the diameter of the inner fixing hole 22. The wall has a recess 23 at the center position. The wall thickness at the recess 23 is thinner than the wall thickness without the recess. One end of the crossarm 3 is fixed to the covering component 2. One end of the support rod is fixed to the covering component 2 and located below one end of the crossarm 3. The other end of the support rod is fixed to the lower surface of the crossarm 3. The cable-passing component 4 is fixed to the surface near the other end of the crossarm 3. The covering component 2 is inserted into the annular groove 11 and is tightly attached to and fixed to the power pole body 1.

[0026] During actual construction, the two covering components 2 are spliced ​​together to completely cover the power pole body 1 in the entire circumference. Since they are located in the annular groove 11, which is concave relative to the outer cylindrical surface of the power pole body 1, the protruding power pole body 1 below the annular groove 11 blocks the covering components 2. This allows the covering components 2 to be effectively supported during installation, making construction and fixing more convenient and faster, and preventing them from easily slipping off.

[0027] During assembly, fixing screws and the like pass through the outer fixing hole 21 from the covering cavity 20 and fix one end of the crossarm 3. Due to the presence of the recessed part 23, the fixing screws can be retracted after fixing. When the covering part 2 is attached to the power pole body 1, the fixing screws will not touch the surface of the power pole body 1 at the annular groove 11. The fixing part passes through the countersunk hole 24 and the inner fixing hole 22 and is fixed to the power pole body 1. The fixing part can be embedded in the countersunk hole 24 and blocked by the inner fixing hole 22.

[0028] The improved power pole described above is characterized in that the cable-passing component 4 is welded or spirally fixed to the crossarm 3.

[0029] The improved power pole described above is characterized in that the cable-passing component 4 is fixed on the upper or lower surface or both surfaces of the other end of the crossarm 3.

[0030] The improved power pole described above is characterized in that the cable-passing component 4 has a cable-passing hole 41.

[0031] The improved power pole described above is characterized in that all cable holes 41 are parallel.

[0032] The improved power pole described above is characterized in that the power pole body 1 is cylindrical.

[0033] The improved power pole described above is characterized in that the power pole body 1 has crossarms distributed in at least a plurality of directions.

[0034] for example Figure 2 In addition to the direction in the middle, it can also be perpendicular to it below, so that it can be used to erect lines in different directions; the above scheme can be implemented by setting screw holes in different directions on the power pole body 1 below the annular groove 11.

[0035] Figure 4 Cable 5 is laid in the cable hole 41.

[0036] Implementation Example 2: Please see Figure 5 and refer to Figures 1 to 4 An improved power pole is basically the same as Implementation Example 1, except that the power pole body 1 is in the shape of a frustum cylinder.

[0037] An improved power pole tower described in this application is characterized in that: the power pole tower body 1, the covering component 2, the crossarm 3, and the cable-passing component 4 are all made of iron or steel.

[0038] An improved power pole tower described in this application is characterized in that: the material of the power pole tower body 1 can also be a composite material.

[0039] The improved power pole described in this application is not limited to power transmission, but can also be used for signal transmission, such as for laying signal cables, optical cables, and integrated / composite optical / electrical cables.

[0040] In this application, the roots of fasteners, such as fixing screws, can be located inside the wall, which is not only aesthetically pleasing but also secure. Sealing components can be used, which makes the surface smooth and waterproof.

[0041] In this application, the support rods serve a supporting function, and multiple rods can be used. They can also be used to support the sides of the crossbeams, making the structure more robust, stable, and reliable.

[0042] This application has the following main beneficial technical effects: simple and convenient assembly; the covering component will not slide down during assembly and use, making it safer and more reliable; the fixing component is effectively protected, so it will not be difficult to maintain due to rust, and replacement is also quite convenient; there are cable-passing components at both the top and bottom of the crossarm, so it can carry more cables; since the covering component can be rotated during installation, cables transmitting in multiple directions can be placed on one power pole, effectively accommodating the erection of cables in different directions.

[0043] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
