Description

Technical Field

[0001] The utility model belongs to the field of power transmission equipment, and more specifically, relates to a combined insulated electric pole. The utility model also relates to a power transmission system, which is provided with the combined insulated electric pole. Background Art

[0002] As the name suggests, electric poles are poles used to support overhead wires. In terms of materials, common poles include cement poles, steel structure towers and fiberglass poles.

[0003] In terms of use and structural form, existing utility poles can be roughly divided into the following six types: (1) Straight poles (also called intermediate poles), which are used to support the conductors that transmit electrical energy and are relatively common. (2) Tension poles (also called load-bearing poles), which are tall and large fixed facilities that mainly bear longitudinal tension and control the range of pole collapse. (3) Corner poles, which are used to support the conductors that transmit electrical energy in the power system. They are mainly used at the bends of the line and are usually tension poles. If the angle of the turn is too large, double cross arms are generally installed to ensure the safe distance between the conductors. (4) Terminal poles, which are tension pole towers that bear unilateral tension and are used to support power lines or communication lines. They are mainly used in power or communication line systems. (5) Crossing poles are used when crossing is required. If the line passes above the object being crossed, the pole should be as close to the object as possible (but outside the range of the pole fall). If the line passes below the object being crossed, the crossing point should be placed between the spans as much as possible. When crossing railways, roads, navigable rivers, etc., the crossing pole should be a tension pole or a reinforced straight pole with a guy wire. (6) Branch poles (also called divergence poles) are poles installed at the branching point of the line conductor. The pole is a tension type in the branching direction and should be able to withstand the full tension of the branch line conductor. Usually a guy wire is added.

[0004] In the above-mentioned uses, the corner poles, tension poles and branch poles are subjected to relatively large tensile forces. Although the overall strength of the steel structure electric tower can meet the use requirements, the existing steel structure electric tower has the disadvantage of high cost. The strength of electric poles made of other materials except steel structure electric towers cannot meet the requirements during use, and improvement is urgently needed. Utility Model Content

[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. 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 3 The combined insulated electric pole provided by the utility model is now described. The combined insulated electric pole comprises an electric pole body 1, a connecting assembly 2 and a first cross bar 3. There are two electric pole bodies 1 and two connecting assemblies 2, and they correspond to each other. The two electric pole bodies 1 are arranged side by side along the first horizontal direction. The two connecting assemblies 2 are respectively arranged on the corresponding electric pole bodies 1 and at the same height. The two ends of the first cross bar 3 are respectively connected to the two connecting assemblies 2, and the first cross bar 3 is perpendicular to the electric pole body 1. The connecting assembly 2 comprises a connecting sleeve 21, a second cross bar 22, a first diagonal brace 23 and a second diagonal brace 24. The connecting sleeve 21 is coaxially sleeved on the electric pole body 1. The outer periphery of the pole body 1, and the inner wall of the connecting sleeve 21 is in close contact with the outer periphery of the pole body 1; the second cross bar 22 is perpendicular to the first cross bar 3 and the pole body 1, one end of the second cross bar 22 is fixedly connected to the outer wall of the connecting sleeve 21, and the first cross bar 3 is overlapped on the second cross bar 22; one end of the first diagonal brace 23 is connected to the first cross bar 3 and is located between the two pole bodies 1, and the other end of the first diagonal brace 23 is connected to the bottom of the outer periphery of the connecting sleeve 21; one end of the second diagonal brace 24 is connected to the middle of the first diagonal brace 23, and the other end is connected to the second cross bar 22.

[0032] It should be noted that, in a specific implementation process, it is necessary to make the first horizontal direction coincide with the direction of the resultant force of the wire pulling force as much as possible, so as to enhance the tensile strength of this embodiment.

[0033] Compared with the prior art, the combined insulated utility pole provided in this embodiment can share the tension of the conductor through two side-by-side utility pole bodies 1, thereby solving the technical problem of insufficient anti-toppling ability of the existing single utility pole. In addition, the first cross bar 3 in this embodiment can be combined with the two utility pole bodies 1 into a frame structure, and the connecting assembly 2 can enhance the stability of the connection between the first cross bar 3 and the utility pole body 1, further enhancing the structural rigidity of the combined insulated utility pole in this embodiment, so that the structural strength of the combined insulated utility pole in this embodiment can meet the use requirements; in addition to the above-mentioned beneficial effects, this embodiment can not only support the second cross bar 22 through the combined assembly of the first diagonal brace 23 and the second diagonal brace 24, but also reinforce it when the utility pole body 1 has a tendency to fall over, thereby enhancing the anti-toppling ability of this embodiment.

[0034] Based on the above embodiment, the connecting assembly 2 further includes a third diagonal brace 27, the top end of which is connected to the second cross bar 22, and the bottom end of which is hinged to the bolt member 213. In this embodiment, the provision of the third diagonal brace 27 can enhance the structural strength of the second cross bar 22, and the bolt member 213 can also connect the third diagonal brace 27 while fixing the connecting sleeve 21, so as to achieve a technical effect of one piece for multiple uses.

[0035] Based on the above embodiment, preferably, the connecting sleeve 21 includes two half shells 211 arranged in a mirror image with its own axis as the center, and the two half shells 211 are symmetrically arranged along the first horizontal direction, and the two half shells 211 are detachably connected by bolts 213. Compared with the prior art, in this embodiment, the connecting assembly 2 can be assembled on the pole body 1 by snapping the two half shells 211 on the pole body 1, and the assembly process is simple and convenient. In addition to the above feasible implementation, in order to prevent the connection between the connecting sleeve 21 and the pole from loosening, in another feasible embodiment, the connecting sleeve 21 also includes a rubber lining 212 provided on the inner wall of the half shell 211. With such arrangement, when the two half shells 211 are tightened by the bolts 213, the rubber lining 212 is tightly attached to the outer wall of the pole body 1, and thus the present embodiment can utilize the friction between the rubber lining 212 and the pole body 1 to prevent the connecting assembly 2 from falling off the pole body 1. At the same time, since the rubber lining 212 has a certain elastic deformation ability, when the connecting sleeve 21 in the present embodiment is adapted to the outer periphery of the pole body 1 with different tapers, the connecting sleeve 21 can be tightly fitted on the outer periphery of the pole body 1.

[0036] In some embodiments, the axial end surface of the half shell 211 is provided with a flange 214 extending in the direction facing the pole body 1, and the width of the flange 214 is less than the thickness of the rubber lining 212. In this way, the flange 214 can protect the edge of the rubber lining 212, prevent the rubber lining from being directly corroded by the outside world, and improve the weather resistance of the connecting sleeve 21 in this embodiment.

[0037] In some embodiments, the outer peripheral surface of the semi-shell 211 is parallel to the up-down direction, and the thickness of the rubber lining 212 gradually decreases from top to bottom. In this embodiment, the connecting sleeve 21 with a consistent outer diameter up and down facilitates the positioning and installation of the first diagonal support 23 and the second crossbar 22. Further setting of the thickness of the rubber lining 212 can make the inner surface shape of the connecting sleeve 21 more closely fit the taper of the pole. Based on the above embodiments, preferably, the thickness of the semi-shell 211 gradually decreases from top to bottom. This setting is based on the consideration that in the process of the connecting sleeve 21 clamping the pole, the internal extrusion force is concentrated toward the top. Further setting of the thickness of the semi-shell 211 in this embodiment can save the material of the semi-shell 211 and reduce the overall weight of the connecting assembly 2.

[0038] In the specific implementation process of the above embodiment, in order to further enhance the tensile strength of the combined insulated electric pole in the first horizontal direction of the utility model, the connection assembly 2 also includes a pull rope 25. Along the first horizontal direction, the pull rope 25 is located on any one side of the two opposite sides of the two electric pole bodies 1. The pull rope 25 is connected with a fixing hoop 251, a thread 252 and a pull plate 253 in sequence from top to bottom. The fixing hoop 251 is coaxially sleeved on the outer periphery of the electric pole body 1, and the fixing hoop 251 is located above the first cross bar 3. The pull rope 25 is connected to the end of the first cross bar 3 through the thread 252, and the pull plate 253 is buried below the ground surface. As set above, under the pulling of the pull rope 25, the pulling force of the pull rope 25 can balance the combined force of the wire pulling the electric pole, so that the structure of the combined insulated electric pole in the utility model is more stable.

[0039] Based on the above embodiment, the connection assembly 2 further includes an adjustment member 26. Corresponding to the adjustment member 26, the pull rope 25 has a first connection section and a second connection section. The fixing hoop 251 and the thread 252 are connected to the first connection section, and the pull plate 253 is connected to the second connection section. The adjustment member 26 includes a first adjustment rod 261, an adjustment sleeve 262, and a second adjustment rod 263 arranged in sequence along the up-down direction. One end of the first adjustment rod 261 is provided with a first hook connected to the first connection section, and the outer periphery of the other end is formed with a first external thread. One end of the second adjustment rod 263 is provided with a second hook connected to the second connection section, and the outer periphery of the other end is formed with a second external thread. The two ends of the adjustment sleeve 262 are thread-matched with the first adjustment rod 261 and the second adjustment rod 263, respectively, and the first external thread and the second external thread have opposite rotation directions. Compared with the prior art, the tension of the pull rope 25 can be adjusted by rotating the adjustment sleeve 262 in this embodiment, so that the tension of the pull rope 25 can be adaptively adjusted according to the tension of the wire.

[0040] Compared with the prior art, the combined insulated utility pole provided by the utility model can share the tension of the conductor through two side-by-side utility pole bodies 1, thereby solving the technical problem of insufficient anti-tilting ability of the existing single utility pole. In addition, the first cross bar 3 in the utility model can be combined with the two utility pole bodies 1 into a frame structure, and the connecting assembly 2 can enhance the stability of the connection between the first cross bar 3 and the utility pole body 1, further enhancing the structural rigidity of the combined insulated utility pole in the utility model, so that the structural strength of the combined insulated utility pole in the utility model can meet the use requirements; in addition to the above-mentioned beneficial effects, the utility model can not only support the second cross bar 22 through the combined assembly of the first diagonal brace 23 and the second diagonal brace 24, but also reinforce it when the utility pole body 1 has a tendency to fall over, thereby enhancing the anti-tilting ability of the utility model.

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

[0042] Compared with the prior art, the power transmission system in the present invention has all the advantages of the above-mentioned combined 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.
