The utility model also relates to an electric power transmission system, which is provided with the segmented insulated electric pole. Background Art

[0002] At present, heavy cement poles and steel poles are commonly used in infrastructure projects for the erection of power lines, such as electricity and telecommunications. Such poles are heavy, especially in construction in complex terrains such as mountainous areas and hills. The complex terrain makes it difficult to transport poles to the set positions even with two-wheeled vehicles, and the labor intensity of power workers is very high. In addition, cement poles are weak and easy to break during transportation. In order to improve the various shortcomings of traditional concrete poles, existing manufacturers generally use fiber winding molding technology to produce fiberglass poles. Fiber winding molding is a method in which continuous fiber roving or cloth tape is impregnated with resin glue under the conditions of controlling fiber tension and predetermined linear shape, and continuously wound on a core mold or lining corresponding to the inner cavity size of the product, and then solidified at room temperature or under heating conditions to form a product of a certain shape.

[0003] However, the wires of the power transmission system often need to be laid in mountainous areas. Although the existing fiberglass poles are light in weight, it is still extremely inconvenient to erect the poles in harsh construction environments. Not only that, some of the existing poles are too long and special vehicles need to be used during transportation, which is in urgent need of improvement. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] Please also read Figures 1 to 4The utility model provides a segmented insulated electric pole. The segmented insulated electric pole includes an electric pole body whose diameter gradually decreases along a first direction. The electric pole body is a cylinder, and the electric pole body includes a first connecting section 1, a second connecting section 2 and a connecting portion 3. The first connecting section 1 and the second connecting section 2 are sequentially arranged along the first direction. The end with a smaller diameter of the first connecting section 1 is coaxially extended along the first direction with a cylindrical plug-in section 11. The inner side of the end with a larger diameter of the second connecting section 2 is coaxially provided with a cylindrical avoidance groove 21. The plug-in section 11 is plugged into the avoidance groove 21. Adaptation: The connecting part 3 includes a connecting sleeve 31 and a heating unit. Optionally, the connecting sleeve 31 is cylindrical and can be sleeved on the outer periphery of the plug-in section 11 or the inner wall of the avoidance groove 21. Of course, providing the connecting sleeve 31 on the outer periphery of the plug-in section 11 and the inner wall of the avoidance groove 21 is also a feasible implementation method; the connecting sleeve 31 is made of hot melt adhesive, and the heating unit includes a heating wire 32 arranged in the connecting sleeve 31 and a conducting wire 33 located outside the connecting sleeve 31, and the conducting wire 33 is conductively connected to the heating wire 32.

[0032] Compared with the prior art, firstly, the present embodiment can assemble the first connection section 1 and the second connection section 2 into a whole through the plug-in adaptation of the plug-in section 11 and the avoidance groove 21, which is conducive to the segmented transportation and assembly of the electric pole, thereby helping to solve the technical problem that the existing electric poles are inconvenient to carry due to their large size and heavy weight; at the same time, the present embodiment can also heat the connecting sleeve 31 through the electric heating wire 32 to bond the first connection section 1 and the second connection section 2 into one, and the bonding connection method makes the connection between the first connection section 1 and the second connection section 2 more secure, thereby improving the structural strength of the electric pole body in the present embodiment; not only that, the connecting sleeve 31 in the present embodiment is integrated into the electric pole body, and the first connection section 1 and the second connection section 2 can be connected as a whole by simply connecting the wire 33 to the external power supply. The operation is convenient and quick, and no additional parts are required.

[0033] In the specific implementation, the gap between the plug-in section 11 and the avoidance groove 21 is adapted, and the thickness of the connecting sleeve 31 is greater than the spacing of the gap. In this way, during the plug-in process, the first connecting section 1 and the second connecting end can squeeze out some of the excess hot melt adhesive, so that the hot melt adhesive can be fully filled in the gap to prevent the formation of a cavity at the connection point between the first connecting section 1 and the second connecting section 2. In addition, the squeezed hot melt adhesive can be scraped off with a spatula or other tool, so that the connection point between the first connecting section 1 and the second connecting section 2 can have a smooth transition, thereby improving the integrity of the utility pole body in the utility model.

[0034] Based on the above embodiment, preferably, a possible implementation is proposed. Specifically, the heating wire 32 is embedded in the connecting sleeve 31 in a mesh shape. In this way, the mesh heating wire 32 distributed in the connecting sleeve 31 can heat the connecting sleeve 31 more evenly, and the mesh heating wire 32 can also enhance the connection strength of the connecting portion 3 between the first connecting section 1 and the second connecting section 2.

[0035] In some embodiments, in order to ensure the connection strength between the plug-in section 11 and the first connecting section 1, the plug-in section 11 and the first connecting section 1 are integrally formed, and the maximum outer diameter of the plug-in section 11 is smaller than the minimum outer diameter of the first connecting section 1, and the outer diameter of the larger diameter end of the second connecting section 2 is the same as the outer diameter of the smaller diameter end of the first connecting section 1. In this way, the outer circumferential surfaces of the first connecting section 1 and the second connecting section 2 are more smoothly connected, which is convenient for coating the subsequent external protective paint.

[0036] Preferably, in a specific implementation process, in order to facilitate the insertion of the second connection section 2 on the first connection section 1, a plug-in protrusion 111 is provided on the outer periphery of the plug-in section 11, and a plug-in groove 211 adapted to the plug-in protrusion 111 is provided on the inner wall of the avoidance groove 21. Compared with the prior art, this embodiment can position the connection between the first connection section 1 and the second connection section 2 through the plug-in adaptation of the plug-in protrusion 111 and the plug-in groove 211, so that the assembly of the first connection section 1 and the second connection section 2 is more portable. Furthermore, there are multiple plug-in protrusions 111, and the number of plug-in grooves 211 corresponds to each plug-in protrusion 111 one by one. Each plug-in protrusion 111 is evenly distributed on the outer periphery of the plug-in section 11 around the axis of the main body of the electric pole, and the length direction of the plug-in protrusion 111 and the length direction of the plug-in groove 211 are both parallel to the first direction.

[0037] In a possible implementation, a closing opening 212 is formed inwardly at one end of the avoidance groove 21 away from the first direction, and a ring groove 112 corresponding to the closing opening 212 is coaxially formed at the root of the plug section 11. In this embodiment, after the hot melt adhesive is solidified, the closing opening 212 and the ring groove 112 can clamp the first connection section 1 and the second connection section 2 under the action of the closing opening 212 and the ring groove 112, even if the hot melt adhesive is separated from the first connection section 1 or the second connection section 2, so that the overall structural strength of the pole body is effectively guaranteed.

[0038] Optionally, in order to facilitate heating of the connecting sleeve 31, one end of the wire 33 is connected to the heating wire 32, and the other end is located outside the pole body and can be connected to an electrical circuit disposed outside the pole body.

[0039] In summary, compared with the prior art, the utility model has the following beneficial effects:

[0040] Firstly, the utility model can assemble the first connection section 1 and the second connection section 2 into a whole through the plug-in adaptation of the plug-in section 11 and the avoidance groove 21, so as to split the existing large-sized electric pole into two or more relatively small combined electric poles, so as to facilitate the transportation of the electric poles; at the same time, the utility model can also heat the connecting sleeve 31 through the electric heating wire 32, and bond the first connection section 1 and the second connection section 2 into one, and the bonding connection method makes the connection between the first connection section 1 and the second connection section 2 more secure, thereby improving the structural strength of the electric pole body in the utility model; and the utility model only needs to connect the wire 33 to the external power supply to connect the first connection section 1 and the second connection section 2 into a whole, which is convenient and quick to operate, and does not require additional parts, making the assembly of the electric pole more convenient and quick.

[0041] Based on the same inventive concept, the utility model also proposes a power transmission system, which includes the above-mentioned segmented insulated utility pole.

[0042] Compared with the prior art, the power transmission system in the present invention has all the advantages of the above-mentioned segmented insulated utility poles, which will not be described in detail here.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
