Description

Technical Field

[0001] This utility model relates to the field of overhead insulated conductor technology, and more specifically, it relates to an overhead insulated conductor that is wind-resistant and tension-resistant. Background Technology

[0002] Overhead cables (full name: overhead insulated cables) are overhead conductors equipped with insulation layers and protective sheaths. They are a special type of cable manufactured using a process similar to that of cross-linked cables. They represent a new power transmission method between overhead conductors and underground cables. Overhead cables are all single-core and can be classified according to their structure into hard aluminum wire structure, hard drawn copper wire structure, aluminum alloy wire structure, steel core or aluminum alloy core support structure, and self-supporting three-core composite structure (the core can be hard aluminum or hard copper wire), etc.

[0003] Overhead insulated cables require the installation of damping wires or vibration dampers on the conductors to enhance their wind resistance. Damping wires reduce the vibration amplitude of the conductor by consuming vibration energy, while vibration dampers absorb and consume the vibration energy of the conductor, effectively reducing fatigue damage caused by wind vibration. To increase the tensile strength of overhead insulated cables, high-strength steel wires or other tensile layers can be installed on the outer layer of the conductors. These layers can withstand greater tensile forces and resist external forces such as strong winds, reducing conductor breakage or loosening caused by tensile forces.

[0004] While fixing a high-strength steel wire or other tensile-resistant layer to the outside of wind-resistant and tension-resistant overhead insulated conductors can increase tensile strength, the need to customize high-strength steel wire or other tensile-resistant layers of different diameters is often required due to the diverse specifications of overhead insulated conductors and the demands of power systems. This results in wasted costs, the inability to quickly install and lock them onto conductors of different diameters, and poor versatility. Therefore, in order to solve the above technical problems, this application proposes a wind-resistant and tension-resistant overhead insulated conductor. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wind-resistant and tension-resistant overhead insulated conductor, so as to solve the technical problem that the tensile layer of the existing wind-resistant and tension-resistant overhead insulated conductor cannot be quickly installed on conductors of different diameters and has poor versatility.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wind-resistant and tension-resistant overhead insulated conductor, comprising an overhead insulated conductor body;

[0007] A tensile layer, wrapped around the outer wall of the overhead insulated conductor body, includes a tensile mesh, wherein the outer wall of the tensile mesh is provided with a number of insertion holes at equal intervals in a straight line, and a metal ring is installed on the inner wall of the insertion holes;

[0008] A one-way locking assembly includes a one-way locking seat, wherein an installation component is mounted on the outer wall of the one-way locking seat and is detachably mounted on the end of the tensile layer through the installation component and the insertion hole, and a one-way locking strip is detachably installed inside the one-way locking seat;

[0009] The one-way locking seat includes a seat frame, a lever is fixed in the middle of the inner side wall of the seat frame, the lever is "J" shaped and the end of the hook section is fixed to the inner side wall of the seat frame, and a pawl is fixed in the outer side wall of the lever;

[0010] The one-way locking strip includes a flexible strip with one end located in the middle of the outer wall of the tensile layer. A ratchet is installed on the outer wall of the flexible strip, which can cooperate with a pawl. The other end of the flexible strip is chamfered.

[0011] Preferably, the tensile layer is a flexible mesh woven from yarns with excellent tensile strength.

[0012] Preferably, there is a gap between the vertical section of the break piece and the inner sidewall of the seat frame, and the end of the vertical section of the break piece extends through the seat frame.

[0013] Preferably, the mounting assembly includes a stud, which is fixed to the outer wall of the one-way locking seat, and a nut is detachably mounted on the outer wall of the stud.

[0014] Preferably, the nut is hemispherical and has symmetrical grooves on its outer side wall.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model discloses a wind-resistant and tension-resistant overhead insulated conductor with an outer tensile layer. One end of the unidirectional locking strip is located in the middle of the tensile layer, and the other end of the unidirectional locking strip is movable. A unidirectional locking seat is detachably installed at the end of the tensile layer. The long side area of ​​the overlapping tensile layer can be adjusted according to the overhead insulated conductor body of different diameters, which can quickly adapt to the overhead insulated conductor body of different diameters. It has strong versatility. When the movable end of the unidirectional locking strip is inserted into the unidirectional locking seat, it is limited by the pawl and the ratchet. Under normal conditions, it can only be tightened in one direction, which has a good locking effect. When disassembly is required, the pry bar is pried to separate the pawl and the ratchet, and the unidirectional locking strip is pulled out, which is convenient and quick to disassemble. This solves the problem that the tensile layer of the existing wind-resistant and tension-resistant overhead insulated conductors cannot be quickly installed and locked on conductors of different diameters, resulting in poor versatility.

[0027] like Figure 1-4 As shown, this utility model provides a wind-resistant and tension-resistant overhead insulated conductor, including an overhead insulated conductor body 1;

[0028] Tensile layer 3, which wraps around the outer wall of the overhead insulated conductor body 1, includes tensile mesh 301. The outer wall of tensile mesh 301 is provided with a number of insertion holes 302 at equal intervals in a straight line. A metal ring 303 is installed on the inner wall of the insertion hole 302 to facilitate the insertion of stud 501 into the metal ring 303 for installation.

[0029] One-way locking assembly 2 includes a one-way locking seat 4. An installation component 5 is mounted on the outer wall of the one-way locking seat 4 and is detachably mounted to the end of the tensile layer 3 via the installation component 5 and the insertion hole 302. A one-way locking strip 6 is detachably installed inside the one-way locking seat 4. The one-way locking strip 6 includes a flexible band 601 with one end located in the middle of the outer wall of the tensile layer 3. A ratchet 602 is mounted on the outer wall of the flexible band 601, which can cooperate with a pawl 403. The other end of the flexible band 601 has a chamfer for easy and quick insertion into the inner wall of the seat frame 401. One end of the tensioning strip 6 can be fixed with a stud 501. It can be detachably installed on the middle of the outer wall of the tensile layer 3 through the cooperation of the stud 501 and the nut 502. At this time, several insertion holes 302 need to be opened in a straight line equidistant array at the corresponding position of the middle of the outer wall of the tensile layer 3, and a metal ring 303 is installed on the inner side wall of the insertion hole 302 to adapt to the overhead insulated conductor body 1 of different lengths. When it is necessary to adjust the length of the tensile layer 3, it can be directly cut to the required length. Then, the one-way locking seat 4 and the one-way locking strip 6 can be detachably installed on the tensile layer 3 through the installation component 5.

[0030] The one-way locking seat 4 includes a seat frame 401. A lever 402 is fixed in the middle of the inner side wall of the seat frame 401. The lever 402 is "J" shaped and the end of the hook section is fixed to the inner side wall of the seat frame 401. A pawl 403 is fixed in the outer side wall of the lever 402. There is a gap between the vertical section of the lever 402 and the inner side wall of the seat frame 401. The end of the vertical section of the lever 402 extends through the seat frame 401. When the movable end of the one-way locking bar 6 is inserted into the one-way locking seat 4, it is limited by the pawl 403 and the ratchet 602. Under normal conditions, it can only be tightened in one direction, and the locking effect is good. When it needs to be disassembled, the lever 402 is pried to separate the pawl 403 from the ratchet 602 and pull out the one-way locking bar 6.

[0031] Furthermore, the tensile layer 3 is a flexible mesh woven from yarns with excellent tensile strength. The flexible mesh can be a steel wire woven mesh, a carbon fiber woven mesh, or an aramid fiber woven mesh.

[0032] Furthermore, the mounting component 5 includes a stud 501, which is fixed to the outer wall of the one-way locking seat 4. A nut 502 is detachably mounted on the outer wall of the stud 501. The nut 502 is hemispherical and has symmetrical grooves 503 on its outer wall. The hemispherical shape of the nut 502 reduces the gap between the tensile layers 3. The symmetrical grooves 503 on the outer wall of the nut 502 facilitate gripping for installation or removal.

[0033] Working principle: The wind-resistant and tension-resistant overhead insulated conductor disclosed in this utility model is wrapped with a tension layer 3. One end of the one-way locking strip 6 is set in the middle of the tension layer 3, and the other end of the one-way locking strip 6 is movable. One end of the one-way locking strip 6 can fix the stud 501. Through the cooperation of the stud 501 and the nut 502, it can be detachably installed in the middle of the outer wall of the tension layer 3. At this time, the corresponding position of the middle of the outer wall of the tension layer 3 needs to be provided with a number of insertion holes 302 with metal rings 303 installed on the inner side wall in a straight and equidistant array to adapt to the overhead insulated conductor body 1 of different lengths;

[0034] When the length of the tensile layer 3 needs to be adjusted, it is directly cut to the required length, and then the one-way locking seat 4 and the one-way locking strip 6 are detachably installed on the tensile layer 3 through the installation component 5.

[0035] The end of the tensile layer 3 is detachably fitted with a one-way locking seat 4. The long side area of ​​the overlapping tensile layer 3 can be adjusted according to the different diameters of the overhead insulated conductor body 1, so that it can be quickly adapted to the different diameters of the overhead insulated conductor body 1, and has strong versatility.

[0036] First, attach one side of the long side of the tensile layer 3 to the overhead insulated conductor body 1, while making the one-way locking strip 6 face outward. Then, wrap the other side of the long side of the tensile layer 3 around the overhead insulated conductor body 1, insert the movable end of the one-way locking strip 6 into the one-way locking seat 4, and the other end of the flexible strip 601 is chamfered to facilitate quick insertion into the inner wall of the seat frame 401, and limit the position by the pawl 403 and the ratchet 602.

[0037] Under normal conditions, it can only be tightened in one direction, with good locking effect. It can be quickly adapted to overhead insulated conductors of different diameters, and has strong versatility.

[0038] When disassembly is required, since the pry bar 402 is "J" shaped and the hook end is fixed to the inner wall of the seat frame 401, there is a gap between the vertical section of the pry bar 402 and the inner wall of the seat frame 401. The end of the vertical section of the pry bar 402 extends through the seat frame 401. By holding the vertical end of the pry bar 402, pry the pry bar 402 towards the gap, so that the pawl 403 separates from the ratchet 602, and the one-way locking bar 6 is pulled out from the one-way locking seat 4, which facilitates quick disassembly.

Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
